The project comprised two distinct phases. Due to cessation of the Stormwater Trust, a draft final report was submitted to the NSW Department of Environment and Conservation (DEC) on 19 December 2004, prior to completion of some components of Stage 2. The purpose of this report is to supplement information, evaluation and materials contained within the draft final report and advise DEC on outcomes of the final program components which are now completed. Further samples of publications and promotional materials contained within the draft Final Report and this supplementary report are available upon request. Recent Components Components of the Blackwattle Bay program which have been completed since submission of the draft final report 19 December 2004 are presented below. For information on business programs, local schools as well as more information on the categories listed below, please refer to the draft final report submitted 19 December 2004. Local community program The remaining actions aimed at improving knowledge and reducing stormwater pollution by the local community consisted of a poster campaign, commitment agreement, educational stormwater grates and written information. An updated evaluation of the local community program is included in Appendix 1. Based upon 100 surveys conducted at gathering places pre, during and post education campaigns being implemented, it was shown that there was a general increase in awareness of the causes of stormwater pollution by the general community. The surveys indicated the need for ongoing education in the catchment to reinforce messages of the program, and also indicated that the community acknowledge actions they take impact upon the catchment. 3 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Posters During the months of January and February 2005, thirty large “City Lights” posters were displayed on street furniture located in the catchment. Smaller “timetable” size posters have also been installed on the rear of bus shelters in the catchment and these will be displayed for a total of 6 to 12 months. The graphic used for the posters is shown under Promotional Materials. A photo taken from a bus stop is shown under Visual Documentation. Postcard prize giveaway Approximately 22,000 postcards were distributed to all residences within the catchment containing information on ways for residents to help improve Blackwattle Bay. A sample was included within the draft final report. By signing a commitment to help improve Blackwattle Bay and returning the card, residents went in the draw to win one of five $200 seafood vouchers from the Sydney Fish Market. Since the draft final report was submitted, over 1,500 commitments were returned to the City, which is a great result. “Fish” stormwater grates In January 2005 the City of Sydney completed installation of 43 "fish grates" in the catchment. See articles under Media Coverage. The anecdotal feedback has been very supportive. Unfortunately however in April, 9 of the 43 grates were stolen and the City was required to reinstate the original grates. It is not known why the grates were stolen, but the matter has been reported to the police. The grates are the only ones in Australia, so identification in another location would be quite noticeable. The grates do have a locking mechanism, however the drainage department are reluctant to use a lock in the event that it would be difficult to locate and remove during a flooding event. Accordingly, whilst the grates are visually pleasing and provide a very good and cost effective environmental educational message, it is unknown at this stage whether Council would continue to install new grates. Information flyers Due to high demand 4,000 extra information flyers were printed as shown under Visual Documentation. These were made available to the public from the Glebe and City One Stop Shops and information counters. 4 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Council services and training Operations staff training One of the key target groups for the Blackwattle Bay Project was Council Operational Personnel. They were selected because of the broad range of potentially polluting activities they complete every day. The City has ISO 14001 accreditation for an Environmental Management System (EMS) which guides the work of it’s operational personnel. In order to ensure any activities offered to operational personnel would fit in with the requirements of the EMS, detailed discussions were held with the EMS Coordinator and the managers of the operational teams. It was decided the most effective way of getting the key environmental messages through to all operational personnel was to offer face to face training sessions for all 420 operational team members. The training was conducted at a range of venues in order to minimise the time operational personnel had to be away from their work. It was also conducted at times to suit the needs of the operational teams. Some sessions were conducted at night while two sessions were conducted in the early morning i.e. a 12.30 am start followed by a 3.00 am start. The Training was conducted over 23 sessions. The objectives of the training were to ensure that through participating in the program operational staff, their managers and other relevant council personnel would: • Understand and acknowledge the potential environmental impact of their work • Know what they need to do in order to minimise that impact • Understand and acknowledge their community, organisational and legal environmental responsibilities • Understand the concept of environmental due diligence and what they need to do in order to ensure they meet their environmental due diligence responsibilities • Know how to identify environmental risks at their job sites and what to do to minimise those risks • Know who the Appropriate Regulatory Authority (ARA) is for their job sites and how to respond to a site visit from a representative of the ARA • Understand and acknowledge the need for an ongoing internal environmental review program. 5 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 The course had five main components as listed below. For more information on the course content, see Appendix 3. 1. Introduction The course opens with a discussion on the personal benefits of a better protected environment. All participants are required to complete the following statement: “I think it is important to protect the environment because ……” Gaining some type of personal commitment from all participants at the beginning of the session provides an excellent platform for the rest of the training program. The issue of “what difference can one person really make” is also dealt with. 2. Identifying and managing Council’s environmental impact Participants select one or two typical jobs they complete and identify the potential environmental impact of those jobs. Participants usually work in small functional groups for this exercise. Parks and gardens staff could select refuelling, spraying or lawn mowing. Road construction staff could select concrete cutting, footpath construction or hot mix spreading, while water and sewer staff could select pipe laying or dealing with sewer overflows. Each group then explains to the rest of the class the potential impacts of their jobs. The trainer asks each group the type of questions a DEC inspector might ask if they were to visit their job sites. This helps to identify basic issues which could require attention e.g. protection of downstream drains, cleaning of tools after a cementing job or the availability of materials safety data sheets. 3. What the laws require Participants are taken through a brief history of environmental law, including the fact that people found guilty of polluting the air in 16th century England were hung. Participants are then provided with a scenario where they apply their own logic to prepare a basic environmental law. Their logical environmental law is then compared to the main elements of the POEO Act. This is a far more effective way of teaching people about what laws require. 6 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 The key concept of due diligence and what it means to every single council employee is also covered in detail. Appropriate Regulatory Authorities are also explained, as are the power of the DEC, the new notices associated with the POEO Act and the way council officers should respond if they have an incident on their site or a visit from an DEC officer. 4. Identifying environmental risk Through this component participants complete a basic desk top review/audit of one of their typical projects. They are asked to identify what would be the worst possible thing that could go wrong on their job sites and how well placed they are to deal with something going wrong. Within this component a series of council case studies are reviewed and the learners are asked to identify what should have been done differently. During this component a series of real time council prosecutions are also examined. 5. Conclusion The course concludes with each participant being asked to nominate what they will do differently, if anything, as a result of completing the work and what they need to do in order to ensure that they act at all times with due diligence and all reasonable care. All participants were asked to complete an evaluation sheet at the beginning and at the conclusion of the training. A detailed summary of the evaluation sheets is included as Appendix 4 of this report. The increase in the level of awareness and commitment to the EMS was heartening. Clearly those responsible for the development and implementation of this system have done a very good job in explaining what the system is all about, the role individuals can play in the system and the benefits that will accrue over the medium to long term through the implementation of that system. There were few if any serious concerns expressed by personnel within the training. Overall it was a worthwhile exercise. 7 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Authorised officer training One of the objectives of the building and development project was to improve erosion and sediment control practices on building and development sites in the catchment. As a part of the initial project, training sessions were offered to Council enforcement personnel on the POEO Act (1997) and how it could be used to encourage better onsite practices. It became clear during those training sessions that enforcement personnel were not that confident in their abilities to identify good and poor quality erosion and sediment control practices. It was therefore decided to develop an erosion and sediment control awareness course for enforcement personnel. A course framework was developed in consultation with Council enforcement team leaders. A copy of that framework which includes course objectives and learning outcomes is included as Appendix 5 of this report. A copy of the Participant’s Manual for this training course is included as Appendix 6 of this report. The course covered: • Environmental impact of sediment • The laws in relation to erosion and sediment control • Erosion and sedimentation – what causes it? • Erosion and sediment control – the tools and systems • Common problems on building and development sites • A site visit A total of six training sessions were offered with 67 people attending the courses. They were a mix of Rangers, Environmental Health Officers and Building Surveyors. The training program was delivered by Mr Chris Gray and Ms Sharon Gaudry of GEMS Pty Ltd. Both have extensive experience in the development and delivery of training programs for the building and development sector. All participants were encouraged to complete an evaluation sheet. A summary of the responses to that evaluation sheet are included as Appendix 7 of this report. Highlights of the evaluation included: 8 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 • Around 85% of participants “strongly agreed” or “agreed” they had a better understanding of the law in relation to erosion and sediment control, which is an exceptional result given that all participants were authorised officers • 90% of participants “strongly agreed” or “agreed” they would be more confident in providing advice to builders on erosion and sediment control • 90% of participants “strongly agreed” or “agreed” they would be more confident in using enforcement on building and development sites in relation to erosion and sediment control matters A number of participants suggested future courses should also include a visit to a site that has poor erosion and sediment control systems in place. Participants would then be asked to identify what improvement the builder should make in order to improve the systems. This will be included in future courses. A number of participants also suggested more focus on city sites. These will also be included in future courses. The long term success of the course will be measured in relation to improved practices on building and development sites in the city area. Information about the course has already been circulated to a number of Councils within NSW and there has been a reasonable amount of interest in the course. There certainly appears to be a need for this type of training program. As a consequence of the authorised officers training, information cards were developed that can be issued to builders and developers as a quick reference to what sediment and erosion controls are required. These cards are included under Promotional Materials. Planning provisions One of the objectives of the program was to develop standard conditions and procedures for planners to check off erosion and sediment control plans submitted with development applications. A significant challenge was the fact that the City of Sydney is now trying to merge the planning requirements of three different Councils i.e. Leichhardt, City of Sydney and South Sydney Councils. While there is a commitment to the development of a single planning process, implementation of that planning process will take some time. A number of fruitful meetings were held with Council’s senior planning staff and authorised officers. There was general agreement that the current standard conditions as applied by the City were unwieldy and needed attention. 9 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 The planners have therefore formed a working party to work with officers from the Blackwattle Bay program. That working party has examined the standard conditions of approval from a number of Councils. They have also held discussions with representatives of the Master Builders Association and a number of leading developers in the area. The City has also recently employed an environmental planner who has been allocated responsibility for this task. Up until someone was allocated responsibility it was an added extra for a number of people and therefore did not receive the attention it required. We are now extremely confident that the draft standard Conditions of Approval will be moulded into a system that is acceptable to all key stakeholders and will be effectively implemented. Those Conditions of Approval are also likely to include the need for Erosion and Sediment Control Plans and Soil and Water Management Plans as part of an application for development in the City. In order to support the people required to prepare those documents, the City will be applying to the DEC to seek permission to use relevant components of their recently completed Erosion and Sediment Control Guideline for local Councils. It is intended to put together an information package for applicants to allow them to better complete Erosion and Sediment Control Plans and Soil and Water Management Plans. It is also intended to adopt the sample checklist that was included in the Department of Environment and Conservation’s draft document. This will then be used by specialist checkers in the Planning Department of the City of Sydney. The City recognises that this type of change to a system that in the past has been less structured will take some time and cause some angst among some of the stakeholders. It is recognised, however, that this sort of system needs to be implemented in order to provide a rigor to the all-important environmental management requirements on building and development work in the local government area. In conclusion, a great deal of time has been spent on this component of the project, and the product will now evolve a lot more easily. The appointment of a specialist officer to this project will also ensure its completion. 10 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Builders and developers program Master Builders Association trial environmental training The purpose of this component was to develop an Environmental Management Plan Training Program for the Building and Construction sector. Recently, the Department of Fair Trading introduced amendments to the licensing of building and construction professionals. All professionals are now required to accumulate 100 Professional Development Points (PDP) every three years in order for their license to be renewed. These points can be accumulated in a broad range of areas including Occupation Health and Safety, Site Management and Environmental Management. The industry PDP program is managed by the Construction Industry and Training Advisory Board (CITAB). Discussions with that Board indicated the need for effective short term training programs for the Building and Construction Industry, concentrating in particular on the development of basic Environmental Management Plans (EMP). CITAB have indicated for example a well planned course could accumulate up to 35 Professional Development Points for licensed builders. This offered an excellent opportunity to both the DEC and the City of Sydney to encourage more effective environmental management on building and development sites. It was therefore proposed that part of the Blackwattle Bay funding was allocated to develop a training program on the development of EMPs on Building and Construction Sites. This training was then trailed with 16 building and construction professionals who have or will operate within the Blackwattle Bay area. The training covered erosion and sediment controls, waste management, EMS and other environmental issues faced by the industry. The training manual Towards Effective Environment Environmental Management on Building and Development Sites is included as Appendix 8. An evaluation of responses by course participants is included as Appendix 9. The main outcome of the evaluation was the strong support for training of this nature. As the course contained a range of information, it was also suggested that the components on erosion and sediment controls be developed as a stand alone package. Accordingly, a training manual was developed and is included as Appendix 10. 11 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Information materials Due to the successful uptake of materials developed as part of the Blackwattle Bay program since December 2004, the following resources were re/printed: • Sets of "Keep the Soil on Site" erosion and sediment control brochures for trades x 2,000 • Spiral bound “Keep the Soil on Site” information booklets for erosion and sediment controls on building sites x 1,500 • Summary information cards on erosion and sediment controls that Rangers can distribute to builders Sydney Fish Market program The purpose of this component was to develop an education program with the Sydney Fish Market and its retailers. A communication strategy for the Sydney Fishmarket has now been implemented. A series of meetings were held with senior market management, who acknowledged the need for an ongoing communications plan. Within those meetings, key stakeholder groups were identified which included: • Fishermen • Wholesalers • Retailers • Commercial customers of wholesalers • The general public Communication strategies were developed and implemented for each of these groups. The first phase of the communication strategy for the fishermen and wholesalers was a series of letters from Fish Market management and follow up articles in their internal newsletters. The purpose of these letters and newsletters was to put all participants on notice that they all had an individual responsibility to ensure the local environment was protected. Meetings were also held with the fishermen to identify the strategies that needed to be put into place in order to ensure the fishermen were aware of their environmental responsibilities and worked hard to meet them. Outcomes from each of the groups are outlined below: 12 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 1. Fishermen These people will require ongoing attention. It was clear from the meetings and other discussions that the fishermen, while acknowledging the need to work harder to protect the local environment, did not see that they had much of an impact on it themselves. Practices like the leaving of full drums of oil on the wharf for someone else to pick up, and the tossing of refuse off the wharf after net cleaning were not seen as too much of an issue. Meetings with the unofficial “managers” of the fishing fleet have, however, been reasonably fruitful. These “managers” have agreed to pass on the need for more effective environmental protection to the other participants. One of the real bonuses of the fishermen program was the successful application by the City of Sydney and the Sydney Fish Market for a waste oil recycling tank. A tank has now been delivered and should lead to significant reductions in the potential for oil spills from the fishing fleet. 2. Wholesalers One of the more unusual aspects of management of the Fish Market is the issue that wholesalers are also the owners of the market, so therefore the Sydney Fish Market team, while having to do some regulatory work, are in fact regulating the work of their bosses. The wholesalers recognised this challenge in a series of meetings and made commitments to do what they can to help protect the local environment. Key issues for wholesalers include: • Trade waste disposal • Waste management • Clean up of wash down areas As part of the communications strategy, a series of checklists are being developed with the wholesalers. These will then become an agreed practice for all wholesalers on the site. The wholesalers as managers of the site have also agreed to encourage their implementation. 3. Retailers Many of their wholesalers have a retail operation. There are also a number of independent retailers. The main issues for the retailers are: • Trade waste disposal • Waste management • Clean up of wash down areas 13 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 A similar strategy has been implemented for the independent retailers. They have also agreed to adopt and implement the checklists when they have been signed off. 4. Commercial customers of wholesalers Approximately 350-500 commercial customers of retailers visit the auction floor of the Fish Market to purchase their product directly from onsite wholesalers. The main issues with these stakeholders are: • Waste disposal • Clean up of wash down areas A simple note has been developed and is being distributed to all commercial customers of wholesalers when they pay their accounts on the auction floor. A copy of that note is also being translated into a number of community languages. Signage is also being developed and will be placed at various sites around the auction floor to reinforce positive environmental messages of the Blackwattle Bay program. Rangers from the City of Sydney have also been encouraged to attend the Fish Market for the early morning auctions. Rangers will write infringement notices for any visitors to the markets who inappropriately dispose of waste from either their motor vehicles or any of the wholesale and retail outlets throughout the premises. The Fish Market is also planning a significant crackdown on people bringing waste onto the site and dumping it in the markets disposal system. They have broad video camera coverage of all corners of the site. They have issued information to all visitors to the site that they are being video taped and warned that if people are identified dumping waste illegally they will be prosecuted. They anticipate the first prosecution to take place within the next couple of months and they are keen to get high levels of promotion through their existing communication networks for that prosecution. 5. The general public An average of 5,000-8,000 people visit the Fish Market every weekend. During peak periods this can rise to more than 50,000. The main environmental impact of these visitors is waste disposal. Officers of the Sydney Fish Market have applied to be trained as authorised litter spotters and be able to complete “Littering from Motor Vehicles” information forms that then get turned into prosecution notices. 14 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 The market has also encouraged Rangers from the Council to visit the site on the weekends and issue infringement notices to anyone disposing of material inappropriately onsite. The Fish Market is also reviewing their bin placement and signs policy. A weekend litter blitz was also convened. The purpose of the blitz was not to issue tickets but to inform people of the importance of disposing of their waste properly. While the blitz seemed to be successful on the day, a review of practices on the following weekend indicated that little had changed. The Fish Market is now considering regular blitzes including enforcement activities. The installation of the litter trap fence separating the Fishmarket from the bay has also been successful in reducing the amount of litter finding its way into Blackwattle Bay. Probably the major benefit for this part of the program has been establishing a good quality relationship between the City of Sydney and the Fish Market. The site is destined for significant development over the coming years and it is important for the City and the Fish Market to maintain this positive working relationship using all aspects of environmental education and enforcement to encourage appropriate onsite behaviour. 15 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Visual Documentation Bus stop poster (shown here on Glebe Point Road and Bridge Road, Glebe). Thirty of these large size posters were mounted for one to two months in high profile locations around the catchment. Smaller posters are also still being displayed on the sides of bus shelters. 16 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 A total of 43 “fish grates” were installed in locations around the catchment to reinforce the message that stormwater drains to local waterways. The grates contain the wording: “Drains to Blackwattle Bay” and “The Drain is Just for Rain”. 17 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Media Coverage Following submission of the draft final report there have been 5 articles in local newspapers about the Blackwattle Bay program. These include: 1. The Inner West Courier - 4 January 2005 2. The Glebe - 6 January 2005 3. The Glebe - 24 February 2005 4. The Inner West Courier - 8 February 2005 5. The Glebe - 14 April 2005 18 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Promotional Materials The following materials were either developed or reprinted since submission of the draft final report: 1. Bus posters 2. Information flyer reprint x 1,000 3. “Keep the Soil on Site” trades brochures reprint x 2,000 4. “Keep the Soil on Site” spiral guideline reprint x 1,500 5. Erosion and sediment control information cards x 4,000 19 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 20 City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Ongoing Commitment The City of Sydney is committed to providing ongoing support to a number of the program elements from the Blackwattle Bay activity. These include: • City of Sydney Rangers, Environmental Health Officers and Planning staff will continue to provide education material to builders and developers not just within the Blackwattle Bay Catchment but throughout the City of Sydney. • The City of Sydney will also continue to offer training from time to time to builders and developers who need advice on implementing effective environmental management. • The City of Sydney has agreed to continue to support the Sydney Fish Market in both their education and enforcement activities. • City of Sydney operational personnel will continue to be provided with opportunities to have input to the ISO 14001 program. The operational training provided in the program ensured a high level of awareness of ISO 14001 and the role operational personnel can play in its implementation. The communication channels identified through the program will now be utilised by Council on a regular basis. • Based on the success of the business assessments, Council will look to conduct similar assessments in other areas, particularly those adjacent to waterways. • There is commitment to apply protocol developed for the review of Erosion and Sediment Control Plans and Soil and Water Management Plans as a part of this project. • Principles of Water Sensitive Urban Design will be applied to new City of Sydney projects and refurbishments where possible. • Pending review of the trials, the City will use the fish grate designs and biofiltration street tree pits in other areas of the local government area. 21 Appendices City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 Appendices Appendices Appendices City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 1. Evaluation report - local community program Appendices Evaluation Report Local Community Program Prepared by February 2005 Blackwattle Bay Community Program Local Environment Survey Evaluation ___________________________________________________________________________ Purpose The purpose of the surveys was to identify whether there was a change in peoples knowledge and attitudes within the Blackwattle Bay area, towards stormwater issues. Process 100 surveys were completed in the pre, post and final program surveys. The surveys were conducted at community gathering places like bus stops and coffee shops throughout the catchment. The pre program surveys were completed before any program activity was undertaken. The post program surveys were completed within three weeks of the conclusion of the postcard distribution and the bus advertising campaign. The final program survey was completed in February 2005. The purpose of the final program survey was to identify whether the messages had been retained despite no program activity for the previous 4-5 months. The outcomes of all three surveys are outlined below. Analysis of Survey Responses Question 1 What suburb do you live in? This question was asked to identify whether the respondent lived inside the Blackwattle Bay Catchment. The following table outlines the percentage of respondents who live in each suburb. The of people who were from ‘other’ suburbs either worked or visited the area frequently. Suburb Glebe Chippendale Pre Program Survey 37% 20% Post Program Survey 80% 0 Final Program Survey 74% 5% Other Newtown Darlington Pyrmont Broadway Forest Lodge Ultimo Question 2 16% 11% 6% 4% 2% 2% 2% 10% 0 0 0 0 5% 5% 8% 6% 0 0 0 3.5% 3.5% Do you know where the streets and gutters of your suburb eventually discharge stormwater flows? This question was asked in order to identify whether people knew that stormwater flowing from the Catchment ended up in Blackwattle Bay. The table below shows the percentage of respondents that answered for each option in both the pre and post surveys. Answer Blackwattle Bay Don’t Know Other Parramatta River The sewerage system Pre Program Survey 7% 73% 13% 2% 5% Post Program Survey 55% 24% 21% 0% 0% Final Program Survey 50% 28% 22% 0 0 Preliminary Analysis The vast majority of people didn’t know where stormwater in their area ended up in the pre survey. The post survey showed an excellent improvement in the knowledge of people living in the Catchment with 55% of people identifying that stormwater flows ended up in Blackwattle Bay. Many respondents indicated that they had received the postcard. In the final survey, recollections of the Postcard were still quite strong, although the power of the message had started to wane. These survey responses indicate the need for ongoing education throughout the catchment in order to reinforce the messages of the program. Question 3 What things can you do to help improve the quality of stormwater flowing down your gutters? Respondents could offer more than one answer to this question. The purpose of this question was to identify whether people saw a link to simple environmental improvement actions and the quality of stormwater. (Please note that percentages do not equal to 100% as respondents could chose more than one option) Answer Pre Program Survey Post Program Survey Not littering 73% 86% Final Program Survey 90% Cleaning up after pet dog 17% 52% 64% Sweeping footpaths and collecting material in bins Disposing of cigarette butts thoughtfully Washing car on the grass or at a car wash Other 30% 39% 32% 17% 25% 28% 17% 33% 20% 19% 17% 10% Preliminary Analysis There appears to be high level of understanding of the importance of not littering within the Catchment. Therefore the program strategies concentrated mostly on the other actions the community can take in order to improve stormwater flows. There was an improvement in understanding that all the other actions were important to improving water quality in the area. The final program survey indicated a slight growth in knowledge of littering and the importance of cleaning up after a pet dog. This could be attributed to the ongoing community interest and local media coverage of these issues. There was a slight drop off in other behaviours that people could adopt. Again, this reinforces the message of ongoing communication in order to achieve positive environmental results. Question 4 In your opinion, do these environmental issues affect water quality in Blackwattle Bay? Can you please identify whether you think the issues have no impact, a little impact or a lot of impact, or if you don’t know. The purpose of this question was to identify whether people saw a link between the following environmental issues and the quality of stormwater. Don’t know Environmental Issue No impact A little A lot Pre Program Survey Littering 3% 1% 6% 90% Post Program Survey Littering 3% 3% 4% 90% 2% 4% 4% 90% 7% 11% 34% 44% 10% 11% 14% 65% 6% 5% 14% 75% 13% 9% 37% 37% 8% 5% 30% 57% 10% 5% 20% 65% 10% 8% 12% 70% 5% 0% 38% 57% Final Program Survey Littering Pre Program Survey Dog Droppings Post Program Survey Dog Droppings Final Program Survey Dog Droppings Pre Program Survey Run off From Parks and Gardens Post Program Survey Run off From Parks and Gardens Final Program Survey Run off From Parks and Gardens Pre Program Survey Building Sites Post Program Survey Building Sites Final Program Survey Building Sites 4% 0% 25% 71% 9% 9% 25% 57% 19% 5% 30% 46% 10% 4% 15% 71% 8% 2% 13% 77% 13% 5% 20% 62% 5% 4% 25% 71% Pre Program Survey Council Works Post Program Survey Council Works Final Program Survey Council Works Pre Program Survey Run off from industrial sites Post Program Survey Run off from industrial sites Final Program Survey Run off from industrial sites Preliminary Analysis The response here links back to the previous question in that people recognise the impact of litter with 90% both in pre and post program surveys suggesting it has a lot of impact on local waterways. Two of the actions targeted in the community program i.e. cleaning up after dogs and attempting to minimise fertiliser and other losses from parks and gardens generated a significant increase in recognition of their impact. While actions not targeted in the community program i.e. building sites, council works and industrial sites were not seen as significant in the post program survey. This appears to indicate that the community is willing to accept that the actions that they can control are also the actions that have the most impact. This can now be built on by Council in all their education programs. The final survey reinforces the information gathered from the previous question which indicates an increase of awareness of the impact of dog droppings in the area. Recent publicity about the fines for builders in relation to inappropriate erosion and sediment control could also be the main reason for an increase in community concern about the environmental impact on building and development works. Question 5 Do you think the water quality, in recent times, in your local waterways has? Declined Stayed the same Improved Don't know Pre Program Survey Post Program Survey 11% 27% 21% 41% 14% 7% 49% 30% Final Program Survey 10% 12% 51% 27% Preliminary Analysis Respondents also had a better understanding of the improvements in water quality in recent times. This is important for people to understand so they are able to see that they can make a difference. There has been very little variation from the post program survey to the final program survey. The fact that the numbers have held up even though there has been very little program activity for the last couple of months is a positive indicator of the impact of educational activites. Question 6 Do you think there is enough information about what people can do to help improve their local environments? not enough enough More than enough Don't know Pre Program Survey Post Program Survey 65% 25% 7% 3% 70% 22% 4% 4% Final Program Survey 60% 25% 10% 5% Preliminary Analysis Results from both surveys were fairly similar in that respondents would like there to be more information about what they can do to help their local environment. This is very positive as it shows a high community interest in the protection of the environment. The final survey is in line with the data gathered from both the pre and post program survey work. This reinforces the importance of Council running a broad range of educational activities and utilising all the available education sources for the delivery of their messages. Question 7 What do you think would be the best ways to get information to you and your neighbours about Council and community environmental programs? Respondents could offer more than one answer to this question. (Please note that percentages do not equal to 100% as respondents could chose more than one option) Pre Program Survey Local newspapers Council newsletters Information in your letterbox Billboards Websites Public seminars Public displays Local Radio Other 50% 10% 47% 14% 13% 5% 6% 10% 12% Post Program Survey 47% 8% 64% 6% 11% 6% 11% 8% 10% Final Program Survey 52% 12% 63% 8% 10% 5% 10% 8% 4% Preliminary Analysis The increase in the value of information in the letterbox is probably indicative of the effectiveness of the postcard. A high regard for local papers also should be taken into account when councils planning any other environmental educational activities. The final survey reinforced the importance of local newspapers. Environmental issues have featured rather heavily in the last few months in local newspapers. The community recognition and potential impact of local newspapers on environmental matters has probably been reinforced by this level of reporting. Question 8 Other Comments In the post survey many people indicated that they had received the postcard in the mail and that they had read it. Members of the community also approached our surveyors to show their interest in the program. Through the final survey, many local residents expressed support for Council’s level of activity in environmental management. The bus stop advertising, the post card, and other targeted information materials had found their mark. Community members were also willing to identify the actions they could take to help protect and preserve Blackwattle Bay which was quite heartening.

The Department of Environment and Conservation (DEC) has been conducting wide ranging community environmental awareness surveys for more than ten years. These have show a steady growth in community commitment and interest in environmental protection. In the 2004 survey the community nominated environmental protection as their 3rd most important issue behind family and friends. Environmental Training Program © 2004 Gems Pty Limited City of Sydney Page 4 How Does Your Work Affect the Local Environment? • Every day you complete tasks that have the potential to impact on the local environment. • Using “Worksheet 1” list two of the jobs you do, identify the tasks involved in completing each of those jobs and identify the possible environmental impacts of each of those tasks.

It is up to all of us to do what we can to minimise that effect _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 7 Section 2 - It is important to Protect the Environment because we have to. The specific laws in relation to Environment Management have changed a number of times over the past few years. The basic principles have not. All Reasonable Care All environmental laws require everyone involved in Council operations to act with “due diligence” or “all reasonable care” to protect the environment at all times. Every single person is responsible for ensuring their activities are carried out in a way that minimises environmental harm. _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 8 What the Laws Require The main law that impacts on the activities of Council field staff is the Protection of the Environment Operation Act (1997). This act pulls together all the old pieces of environmental protection legislation. The principles of what those laws require, however, has remained unchanged. Air Pollution You can’t allow fumes, dust or smoke to escape into the atmosphere Water Pollution You cannot allow any material to run from your premises into street gutters, drains or waterways either on or outside your properties You cannot place any chemicals in the sewer system without a licence _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 9 Noise Pollution You cannot make disturbing noise at any time Waste and Litter You must, when disposing of hazardous or dangerous chemicals, make sure you are using a licensed waste contractor. You must keep your site tidy at all times You must store your wastes in a way that they will not cause pollution Chemicals All chemicals must be stored in appropriate protected and bunded areas These are the main areas where the environmental laws could impact on your activity. If you have some concerns about something you are doing and the laws in relation to it, contact your Supervisor or members of the Environment Team _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 10 What Happens if the Law is broken? There are three tiers of penalty for breaking the law. Tier 3 For minor offences that lead to minimal environmental harm. The penalties for these minor breaches are specified in the law. Penalties are issued as Penalty Infringement Notices or ‘on the spot’ fines. The penalties include: Problem Penalty Penalty (individual) (company) Polluting waters $750 $1500 Causing air pollution $750 $1500 Cause emission of noise $200 $400 Waste dumping $750 $1500 Permit land to be unlawfully used as a waste facility $750 $1500 Littering (including from vehicles) $200 $400 Failing to comply with a clean-up notice $750 $1500 Failing to comply with a prevention notice $750 $1500 _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 11 Tier 2 The same offences as for Tier 3 but have more serious impact. The penalties for Tier 2 offences are: Individuals: Corporations: maximum $125,000 fine maximum $250,000 fine Tier 1 For incidents that lead to serious environmental harm. The penalties for Tier 1 offences are: Individuals: maximum $250,000 fine plus maximum of 7 years goal plus clean up costs, frozen assets and damages Corporations: maximum $1,000,000 fine plus clean up costs, frozen assets and damages _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 12 Who’s In Charge? • POEO Act makes council clearly responsible for managing the environmental impact of most of the industry in their area. They are what is called the Appropriate Regulatory Authority (ARA) for their area. • ARA for Councils is the DEC. That means the DEC officers can come onto your job sites and require you to more effectively control the environmental impact of those job sites. _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 13 What Powers do Council and the DEC have? Under the POEO Act, Council and the DEC have powers to issue special notices to control the pollution impacts of industry. These notices include: Clean Up Notice • Can be issued when a pollution incident has occurred or is likely to occur. • Can require immediate action • Must specify a period in which the clean up must be taken • No right of appeal - ignoring a notice is against the law • Recipient required to pay a fee for receiving the notice $320.00 • ARA keeps the money _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 14 Prevention Notice • Can be issued when an activity is being carried on in an environmentally unsatisfactory manner. • Should specify actions required to ensure activity is carried on in an environmentally satisfactory manner • Cannot require action within 21 days • Can be appealed • Recipient required to pay a fee for receiving the notice $320.00 _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 15 Other Notices Noise Control Notices Usually technical. Specify noise levels that must be adhered to. Penalty Infringement Notice (PIN) Penalty infringement notices are used when people have broken the law. Compliance Cost Notices Are to enable councils to recover the costs of ensuring compliance with clean up and prevention notices. Other Issues Failure to notify The bottom line is that Government now has the power to stop pollution before it happens. _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 16 Environmental Laws Are Not Just About Controlling Pollution Local Government Act 1993 Under the Local Government Act (1993) for example, Council is required to: • be environmentally responsible; • act in an ecologically sustainable manner • maintain ecosystem function. _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 17 Case Studies _________________________________________________________________ Environment Training Program © 2004 Gems Pty Limited City of Sydney Page 18 Section 3 - It is important to Protect the Environment because Council says so. The City of Sydney has a broad ranging commitment to protecting the environment that commitment is supported by a quality / EMS policy. Key components of that policy declare We will identify the activities, products and services that can interact with the environment, whether adverse or beneficial. We will prepare environmental improvement plans to improve the effects of these aspects on the environment. Our aim is to be regarded by our customers as the provider of choice by a commitment to compliance with all relevant environmental and general legislation and regulations, and with other requirements to which the organisation subscribes.

Evaluation report - operations staff Appendices Backwattle Bay Project Operations Development Program Evaluation Report March 2005 Council Operational Training The training has had an immediate impact on the knowledge and understanding of Council Operational personnel. A comparison of the responses to each of the key questions is outlined below. 1. What do you think you can do to help minimise your impact on the environment in your job? Pre Training Nothing 8% A little 37% Fair Bit 40% A lot 15% A little 15% Fair Bit 54% A lot 31% Post Training Nothing 0% There was a significant increase in awareness among learners about what they could do to help minimise their impact on the environment. This can now be built on by further information from management particularly in relation to standard work methods and links to environmental protection. 2. In your position, how would you describe your level of understanding of environmental responsibilities in accordance with the law? Pre Training Nothing 11% A little 55% Fair Bit 26% A lot 8% A little 30% Fair Bit 47% A lot 21% Post Training Nothing 2% The number of Council personnel who have a “fair bit” or high level of understanding of their environmental responsibilities in accordance with the law almost doubled as a result of the training program. This is an excellent result. 3. How does your job affect the environment? Pre Training Not at all 9% A little 48% A significant amount 43% A little 37% A significant amount 61% Post Training Not at all 2% Prior to the training more than 9% of Council operational personnel did not believe their work could effect the environment. That was reduced to 2% at the conclusion of the training which is a good result. 4. If there is anything that you should be doing to help minimise the environmental impact of your work, please describe it Pre Training 78% of respondents offered a response. Responses varied. A sample of the responses is below • • • • • Be aware Contain all spills and dispose of all rubbish Minimise noise Use unleaded petrol Don’t know Post Training 77% of participants nominated a response. Responses varied. A sample of the responses is below • • • • Water Contamination Greater care More knowledge Better management of what we do The general response was that more care and awareness should be taken with actions that can potentially impact the environment. While there was no significant change in the number of officers nominating what they should be doing to help minimise the environmental impact of the work, there was an improvement in the quality of responses in post training evaluations which indicates a better understanding of the differences Council officers can make if they manage their job sites properly. 5. If you want advice on environmental matters, who in Council would you speak to? Pre Training 75% of participants nominated a response. The main responses were • • • • Don’t Know Supervisor Environmental Officer Quality Manager Post Training 88.5% of participants nominated a response. • • • • • Nik Midlam Swati Metha Supervisor Manager Environment Officer Even though there was an increase in the number of people nominating who they would speak to in relation to environmental matters, there was still not a clear level of understanding as to who would be the best person to contact. To that end it is recommended a note be prepared to all operational personnel listing the key environmental contact numbers for both advice and emergency response. 6. Current environmental laws require everyone to act with “due diligence”. Please describe what that means. Pre Training 53% of respondents nominated a response. Responses varied. A sample of the responses are below • • • • • • • To be aware of the impact our work has on the local environment and attempt to do as little damage as possible Keeping on top of things Donk Know Use common sense To follow OH&S guidelines Common sense Do the right and smart thing Post Training 78% of participants nominated a response. Responses varied. A sample of the responses are below • • • • • Systems in place to ensure all care is taken to prevent incident Taking reasonable efforts to protect the environment Be aware To implement reasonable amount of care Do your best A comparison of the quality of comments in pre and post training surveys indicates a much better understanding of the concept of due diligence as a result of the training. The remaining questions were only asked as a part of the post training evaluation process 7. How relevant was the course to you in your day-to-day work? Very relevant 49% Relevant 48% Not relevant 3% 97% found the course very relevant or relevant to their everyday work. 8. Have you got a better understanding of the Protection of the Environment Operations Act? Yes 84% A little 13% No 3% 9. Do you think it would be worthwhile for your staff to attend this training? Yes 99% No 1% 10. What will you do differently (if anything) as a result of participating in this training course? 65% of participants offered a response. Responses varied. A sample of the responses are below • • • • • • More awareness of prevention Cleaning up waste and disposal of Take more care Think more about general house keeping on work sites A lot more than what I am doing now Increased awareness of my responsibilities This willingness to change practice as a result of the training is an indicator of the enthusiasm with which the training was greeted by some Council personnel. It is very important, however, that Council management recognise the new interest of Council personnel and looks to respond to it wherever appropriate. 11. General Comments 27% of participants offered a response. Responses varied. A sample of the responses are below • Very informative • • • • This has been very educational Good course Course done very well by Chris Gray Well informed and structured course Summary The surveys indicated significant improvement in the level of knowledge, understanding and commitment on the part of Council personnel in minimising the environmental impact of their work. The challenge is now how to build on that new commitment. Appendices City of Sydney Addendum to Final Report NSW Stormwater Trust Grant No: ST/G 3026 5.

Authorised Officer Training © 2005 Gems Pty Limited City of Sydney 3 Section 2 – The Laws The main laws that govern the management of erosion and sediment control on building and development sites are: 1.Environmental Planning and Assessment Act (1979) • Development applications – builders/developers are often required to submit erosion and sediment control plans or soil and water management plans with applications. • Development consent – Council usually includes erosion and sediment control conditions on development consent. A number of sections of the EP&A Act give Councils authority to act against builders or developers who breech their conditions of consent. The tools that can be used in the relevant sections of the Act include: • PIN – Section 127a: most often used for non-compliance with development consent and conditions; • Other sections include 125(1) 125b, and Section 123. Authorised Officer Training © 2005 Gems Pty Limited City of Sydney 4 2. Protection of Environment Operations Act (1997) Basic thrust of this law is the concept of due diligence. The law also introduces new enforcement tools: • Clean Up Notices (Section 91); - Can be issued when a pollution incident has occurred or is likely to occur; - Can require immediate action; - Must specify a period in which the clean up must be taken; - No right of appeal - ignoring a notice is against the law; - Recipient required to pay a fee for receiving the notice - $320.00; - ARA keeps the money.

Authorised Officer Training © 2005 Gems Pty Limited City of Sydney 8 Section 4: The Tools and Systems Minimising Erosion 1. Minimising Impact of Flowing Water • Diversion of upslope water where practical. Upslope water should be diverted around the site. • Small turf or geotextile lined catch drains or diversion banks can be used. • Diverted stormwater should be discharged onto stable areas, and should not be diverted into neighbouring properties; • Connect downpipes to stormwater as soon as gutter is fixed; • Diversion of water around onsite stockpiles; • Designated rubbish areas 2. Minimising Raindrop Impact • Maintain as much vegetation on site as is practical; • Encourage mulching of cleared areas; A range of tools available for mulching, including: • Plant material • Fabrics. Authorised Officer Training © 2005 Gems Pty Limited City of Sydney 9 3. Minimising movement on site • Established stockpile areas; • Established waste minimisation areas; • Established stabilised exit/entry point – usually required by Council’s Standard Conditions of Approval.

Should be designed and signposted to ensure it is common entry and exit point for all movements on and off site. Construction notes – see green booklet. Authorised Officer Training © 2005 Gems Pty Limited City of Sydney 10 Sediment Control Sediment control is about putting in place systems that slow the flow of sediment laid water in order for sediment to settle out and be captured. A range of tools are available for sediment control, including: • Sediment fencing; • Sediment socks; • Straw Bales; • Sandbags; • Sand or gravel sausages; • Sediment traps; • Turf strips. See Appendix 2: “Basic Erosion and Sediment Control Tools – Advantages and Disadvantages” for more information. Authorised Officer Training © 2005 Gems Pty Limited City of Sydney Section 5 – Common Problems Typical Problems Include… • No systems or tools at all; • Right systems of tools but in the wrong place or poorly fitted; • Wrong systems; • Poorly maintained systems. • Sediment fence not dug in 150mm; • Stakes in sediment fence too wide apart; • Sediment fence constructed across the contour, no turn backs; • Sediment fence fitted in areas of concentrated flow; • No stabilised entry; • No upslope drain controls; • No diversion around stockpiles; • Stockpiles above 2m high; Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 12 • Downpipes not connected as soon as roof is completed; • Hay bales used in the wrong place; • Removal of all vegetation from site when it’s not necessary; • Removal if potential filter strips, i.e. bushland or turf, before any construction occurs; • Poor management of subcontractors on site. See Appendix 3 – Onsite Erosion and Sediment Control Audit Tool Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 13 Summary Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 14 Appendix 1: Summary of the Laws Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 15 An Overview of the Laws relating to the management of erosion and sediment control on Council and other building and development sites There are general laws that outline Councils broad environmental responsibilities and specific laws that outline Council operational and management enforcement responsibilities. Outlined below is the summary of the requirements of those laws. The Local Government Act 1993 (as amended 1997) The Local Government Act outlines overarching responsibilities for Council in terms of ensuring the local environment is effectively managed. The first stated purpose of the NSW Local Government Act (section 7a) is ‘to provide the legal framework for an effective, efficient environmentally responsible open system of local government in NSW.’ Another stated purpose of the Act (section 7e) is to ‘require Council’s, Councillors and Council employees to have regard to the principal of ecologically sustainable development in carrying out their responsibilities.’ The Local Government Act 1993 (as amended 1997) (section 8) sets out the charter of a local Councils in NSW and includes the requirements for a Council to ‘properly manage, develop, protect, restore, enhance and conserve the environment of the area for which it is responsible.’ Section 402 of The Local Government Act (1997) sets out the contents of a Council’s draft management plan and also requires that the statement of principal activities must include particulars with respect to ‘activities to properly manage, develop, protect, restore and conserve the environment.’ So the Local Government Act sets a broad agenda for Council. Specific links could then be made from this act to Councils erosion and sediment control responsibilities in all areas of activity. It should be noted that Council does have power to issue enforcement notices under Section 124 of the Local Government Act but the general view of Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 16 Councils identified through the research was that the Protection of the Environment Operations Act (1997) was a much more useful and flexible enforcement tool. Protection of the Environment Operations Act (1997) This is the main environmental protection law in NSW. This law can be used by the Department of Environment and Conservation (DEC (NSW)) to deal with inappropriate practice on Council sites. It can also be used by Council to deal with inappropriate practice on building and development sites in their area. This Act requires any individual or organisation carrying out any activity to ensure that activity is completed with ‘due diligence’ or ‘all reasonable care’ in order to ensure the environment is protected. The DEC (NSW) has indicated in a number of publications that ‘due diligence’ means: • taking all reasonable steps to prevent pollution and protect the environment • promoting action to prevent or minimise potential environmental damage • showing that all that could have reasonably been done to prevent an incident from occurring has been done • ensuring that all precautionary and control measures are in place and are regularly checked and maintained to minimise the risk of an environmental incident. As well as the broad due diligence requirements, the Act also provides the DEC (NSW) and Council with some specific enforcement tools. These tools include a) Clean Up Notices (Section 91). Under Section 91 of the Act, authorised officers do not have to wait for the environment to be harmed before they can take action. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 17 Authorised officers from both the DEC (NSW) and Council can issue Clean Up Notices at sites where they are of the view that an incident has occurred or is likely to occur. The Clean Up Notice is a direction notice and not a penalty notice in that its purpose is to direct the person or organisation receiving it to take action in order to minimise environmental harm. The Notice must outline the actions required in broad terms and must specify a deadline for those actions to be taken. A Clean Up Notice can require immediate action. A Clean Up Notice can also be served verbally but must be followed up in writing within 72 hours. Clean Up Notices are also not appealable and so any person receiving a Clean Up Notice must do what it says. If a person receiving a Clean Up Notice decides not to take the nominated actions, they can receive a Penalty Infringement Notice (PIN) for a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 000 for individuals and $250 000 for corporations. Councils and the DEC (NSW) can also charge an administrative fee of $320 for the issue of a Clean Up Notice. Failure to pay this fee can also attract a fine for up to $1000. Councils and the DEC (NSW) can decide not to impose the fee. Clean Up Notices appear to be the most widely used enforcement tool for minimising erosion and sediment loss on building and development sites. Clean Up Notices can be used for example on building sites with no or poorly maintained erosion and sediment control in place even if it’s not raining. Councils have also used Clean Up Notices to require developers to sweep the streets around their development sites at the end of every day. There is also authority within this Act for Councils to take the clean up action themselves if the person receiving the notice chooses not to within the designated time. Councils can recover the costs associated with completing this work from the person or organisation who received the original notice (see Part C – Compliance Cost Notices). Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 18 b) Prevention Notices (Section 96). Prevention Notices are for more systematic environmental challenges. They are used in response to ‘environmentally unsatisfactory behaviour.’ Prevention Notices are appealable and so cannot require action within 21 days. A Prevention Notice also outlines the actions a person is required to take and provides a deadline for those actions to be completed. If a Prevention Notice is not appealed or upheld on appeal and a person chooses not to carry out the actions outlined in the prevention notice it is a breach of the POEO Act and will attract a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 000 for individuals and $250 000 for incorporations. The DEC (NSW) and Council can also charge an administrative fee of $320 for serving the notice. Given the need to allow 21 days for any action to be implemented, it is unlikely that many Prevention Notices will be used to encourage more effective erosion and sediment control on Council or privately operated building and development sites. c) Compliance Cost Notice (Section 104) Compliance Cost Notices enable Councils to recover the costs of ensuring compliance with Clean Up and Prevention Notices. These costs can include the cost of monitoring action taken under a Clean Up or Prevention Notice and the cost of a Council doing a clean up voluntarily or under direction from the DEC (NSW). For example if Council issues a Clean Up Notice to a developer requiring them to sweep the streets at the end of every day and upon investigation finds this action has not been taken, and Council is within their rights to bring the Councils street sweeper to the site in order to carry out the Clean up Action. The cost of the street sweeper as well as the cost associated with the Council officer visiting the site can all be included in a Compliance Cost Notice. Council is also within their rights to fine the developer for non compliance with a Clean Up Notice. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 19 d) Penalty Infringement Notices (PIN). (A range of Sections) Most erosion and sediment control breaches will be dealt with through the issue of a Penalty Infringement Notice. The Penalty Infringement Notice operates like an ‘on the spot fine.’ The fines attached to Penalty Infringement Notices are set in the Act. A sample of those are outlined in the table below. Examples of Offences from POEO Regulations failing to comply with a clean-up notice failure to pay a clean-up notice fee failing to comply with a prevention notice failure to pay a prevention notice fee polluting waters causing air pollution Proposed Penalty (individual) $750 $500 $750 $500 $750 $750 Proposed Penalty (corporation) $1500 $1000 $1500 $1000 $1500 $1500 Section of Act 91 94 97 100 120 124 – 8 Penalty Infringement Notices are appealable. It is imperative therefore when issuing a Penalty Infringement Notice that all care and attention is taken to the gathering of appropriate evidence to support your case for the issue of a PIN. e) Other Penalties The POEO Act has a three tier offensive system. Tier Three offences (minor offences) are dealt with through the issue of a Penalty Infringement Notice. Tier Two offences can attract penalties of up to $250 000 for corporations and $120 000 for individuals. Tier One offences are the most serious environmental offences. They can attract fines of up to $1 million for a corporation, clean up costs, frozen assets and damages while for individuals the penalty can be up to $250 000 and/or seven years imprisonment as well as clean up costs, frozen assets and damages The POEO Act is a very flexible and useful piece of legislation. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 20 Environmental Planning and Assessment Act (1979) The Environmental Planning and Assessment Act (EP&A) (1979) gives Councils responsibility for the management of their land. That management responsibility operates over a number of levels including • • Land use planning (Part 3). Through the EP&A Act Councils are required to prepare and manage land use plans. These land use plans also impose development controls Development assessment (Part 4). Through this part of the Act Councils are required to assess the suitability or otherwise of all developments in their area. Councils can exclude certain types of activities from the formal assessment process yet these are usually only very minor. Councils can also require specific erosion and sediment control plans or soil or water management plans at the development assessment phase. Councils across the state have different approaches to the process of development assessment. Some have a common approach of requiring an Erosion and Sediment Control Plan for developments up to 2500 square meters and a more detailed Soil and Water Management Plan on developments over that size. Other councils decide on their erosion and sediment control requirements on an ‘application by application’ basis. If the applications do not meet Councils requirements it can be rejected. • Development consent. Councils usually impose erosion and sediment control conditions on development consent. These conditions can vary from basic requirements through the use of standard conditions to more detailed job specific requirements. A number of sections of the EP&A Act give Councils authority to act against builders or developers who breach their conditions of consent. The tools that can be used in the relevant sections of the Act include o PIN – Section 127a o CAN – Section 125(1) through local court prosecution o Summons – Section 125(1) through Land and Environment Court prosecutions o Order 15 – through Section 121b Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 21 o Application for Land and Environment Court orders – Through Class 4 Section 123 Through this Act Councils have the authority to minimise the potential of erosion and sediment control of the planning and application phases as well as through the construction phase. Different councils across the state used the key parts of the legislation differently. Many have found the EP&A Act to be successful in ensuring local environments are protected. Others have found the POEO Act to be more helpful. Other Legislation While the three main laws outlined above are the main ones that Councils need to be aware of, there are many other pieces of legislation that Councils need to comply with, including for example: • National Parks and Wildlife Act (1974) • Threatened Species and Conservation Act (1995) • Coastal Protection Act (1979) • NSW Heritage Act (1977) • Fisheries Management Act (1994).

Sediment control measures aim to capture eroded soil particles by either slowing the velocity of water flow so that soil particles can settle out by gravity or by chemical treatment to flocculate suspended soil particles. As sediment is only generated when soil erosion occurs, installation or construction of erosion control measures should be the first priority. Erosion control is also easier and cheaper than sediment control. Although the list of measures is comprehensive it is not exhaustive. New erosion and sediment control technologies are being developed all the time. The measures described are proven and are known to work if designed and implemented correctly. Permanent erosion and sediment control measures require formal design. Failure to undertake formal design in most instances is an unacceptable risk. Erosion and sediment control is not rocket science, however, inappropriate or poorly designed or installed control measures can often cause more problems than they solve. When in doubt seek independent expert advice. Many self proclaimed erosion and sediment control experts are product suppliers and therefore have a vested interest in promoting their product over what is right for the sight. Be aware of this when seeking erosion and sediment control advice from salesmen. Expert advice can be obtained from Certified Professionals in Erosion and Sediment Control (CPESC) through the International Erosion Control Association (Australasia) (IECA). The Government guideline “Managing Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 24 Urban Stormwater – Soils & Construction” or also known as the “Blue Book” is a great reference book that can assist with selection of products. b) EROSION & SEDIMENT CONTROL MEASURES Surface Roughening – Track Walking Description: A technique that leaves the soil surface in a roughened state to increase water infiltration, decrease and slow down run-off and to encourage sediment retention and vegetation establishment. It also discourages vehicular traffic across the soil surface. Application: For any slope that is safe for the use of machinery. For trackwalking maximum 1(v):2(h). Installation Aspects: Upslope run-off should be diverted away from the slope to be treated. Problems: Upslope stormwater is not diverted around area and rill erosion will occur. Turf Description: Refers to a layer of topsoil and grass harvested from the field by specialist machinery. Rolls can be supplied up to 5 m wide by 9m long. Reinforced turf in similar to conventional turf except that grass is grown through an artificial 2 dimensional poly-propylene grid to provide additional strength. Application: Turf and Reinforced Turf can be used in both sheet flow and concentrated flow situation to provide erosion protection. It is often used as a “softer” alternative to “hard” channel linings such as rock and concrete in urban situations. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 25 Design/Construction Aspects: Turf is only capable of withstanding relatively low flow velocities. Reinforced Turf can withstand flow velocities a lot higher than turf. Deposited sediment can kill turf. For this reason upstream erosion protection and sediment detention measures must be installed before the turf can be placed. As turf and reinforced turf rely on the grass root system for strength, the substrate on to which the turf is being placed must be suitable for vegetation establishment. The edges of the turf/reinforced turf must be installed flush with the existing soil surface so that erosion along the turf/soil interface does not occur. Problems: Deposited sediment can kill turf. Due to the way reinforced turf is grown, the roots can become “root bound” and therefore the time for the roots to bind into the soil surface is increased thus increasing the erosion/failure potential. Turf must be watered until adequately established. Erosion Mats and Blankets Description: A rolled matt or blanket made from jute, coconut fibre, wool, nylon and poly-propylene that is placed on the soil surface to protect it from raindrop impacts and low velocity sheet and concentrated flows. Application: Erosion control blankets are used on batters and embankments and other sheet flow environments to protect the soil from erosion and promote vegetation. Blankets are generally temporary measures and are designed to biodegrade. Typically these products are made from wood fibre, wool and jute. Erosion control matts are designed to be used in concentrated flow environments and are therefore made from more durable materials such as jute, coconut fibre, nylon and polypropylene. Design/Construction Aspects: Due to the vast range of proprietary products available, independent advice should be sought on the appropriate matt/blanket for a particular situation. Manufactures supply product specifications and installation guidelines. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 26 Problems: When blankets are placed in concentrated flow areas. A blanket is designed to cover the ground from raindrop impact and a matt is a heavier product designed for concentrated flow. Remember B is for blanket as in Batter. Rock Check Dams Description: A small temporary rock weir structure. constructed from sandbags and logs. Can also be Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. The middle of the Check Dam must have a spillway to stop water running around the ends. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. Surface Mulching Description: Mulching is the placement of a protective cover over the soil surface to protect it from the erosive effects of raindrop impact and shallow Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 27 sheet flows. Common mulch materials include wood chip, straw, wood fibre, paper pulp, bagasse, brush matt and bitumen emulsion. Application: The type of mulch to be used in dependant on the type of environment to be protected, climatic conditions, location and available mulch material. Design/Construction Aspects: Common to most situations where mulches are to be used, divert flows away from the area to be protected. The application of mulch material should be even and uniform. Problems: Mulch washed away due to failure to divert flows away from mulched area. Erosion due to insufficient quantity of mulch or tackifier. Weed infestation due to weed contaminated mulch (eg hay instead of clean straw). Vegetation Description: For erosion purposes vegetation includes native and introduced grasses, ground covers, shrubs and trees. Application: Any erosion control program will benefit from temporary and permanent vegetation covers. The above ground vegetative material provides protection from raindrop impact slows flow velocities and traps eroded soil particles. Roots help bind the soil surface thus minimising erosion. Problems: Weed infestation due to the use of contaminated seed. Difficulty in maintaining an adequate vegetative cover due to climatic/soil constraints. Sediment Fence Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 28 Description: A sediment fence is a temporary barrier of permeable geotextile, partially installed in a trench and supported by posts. Design/Construction Aspects: Not to be used in concentrated flow. Silt fence should be installed on the contour with the ends turned up so that the turn-up ground level is equal to the top fabric level at its lowest point. Sediment fence must be anchored in a 150mm deep compacted backfilled trench. The sediment fence posts must be on the downslope side of the fabric otherwise the fabric will come away from the peg when put under pressure. Problems: Not installed with a turnback at either end causing water to run around the ends. Not trenched in deep enough causing fabric to pull out of the ground. Not compacting the trench after installation causing water to tunnel under the sediment control fence. (you only need to compact the ground with you boots no need for a compactor to be brought in) Check Dams Description: A small temporary rock weir structure. constructed from sandbags and logs. Can also be Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 29 Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. Straw Bales Description: A small temporary dam. Straw bales are suitable for low flows of water. It is only recommended that these be used in limited applications. They maybe used to reduce the flow velocity of water. Design/Construction Aspects Not to be used in concentrated flow. Straw bales should be installed on the contour with the ends turned up so that the turn-up ground level is equal to the top of the middle bale. Straw bales should be anchored into the ground 100mm with a star picket post to secure. The minimum number of straw bales to be used is four. You can not make a dam with one or two straw bales. Problems: Erosion around the edge of the straw bale dam due to insufficient spillway depth and insufficient number of bales used. Remember minimum number of bales to be used is four. Erosion immediately downslope of the straw bale dam to insufficient rock protection. Sand Bags Description: Sand bags are used to make a temporary sediment trap and are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally do not have an outlet they form a pond. Application: Their function is to trap coarse sediments in both concentrated and sheet flow situations. They should be located immediately downstream of disturbed areas. Authorised Officer Training City of Sydney © 2005 Gems Pty Limited Page 30 Design/Construction Aspects: Sediment traps can be formed by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include not building the structure large enough to contain the amount of water that will be washed from the site. Difficulty in cleaning out sediment, due to poor location and design. Sediment Traps Description: Sediment traps are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally consist of a stable inlet and outlet, and some form of pond. Application: Their function is to trap coarse sediments in concentrated flow situations. They should be located immediately downstream of disturbed areas. Design/Construction Aspects: Formal design of sediment traps is required. Sediment traps can be formed by excavating an earthen pond, or by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include inlet and outlet erosion due to inadequate erosion protection. Difficulty in cleaning out sediment due to poor location and design.

MBA Environmental Training Course 7 iii) Your staff will welcome it (eventually) • Gold Coast City Council • Orica iv) What happens if we don’t? • Reduced quality of life. • Impacts on health. • Impacts on economic returns. • Impacts on our future. MBA Environmental Training Course 8 Section 2 – What the Environmental Laws Require MBA Environmental Training Course 9 2.1 Enforcement as a tool for behaviour change The two main tools available for Councils and the DEC to encourage appropriate environmental behaviours are education and enforcement. For many groups, education is all that is required. For others, a mix of education and enforcement is essential, while for a small group, the only effective tool they will respond to is enforcement. Any DEC or Council program will include elements of both. The use of a mix of education and enforcement has proven very successful in a number of environmental programs including the DEC’s “Don’t Be A Tosser” campaign. 2.2 The Environmental Planning and Assessment Act (1979) (the planning law) The Law Operates at three levels: i) Land Use Planning (Part III) Identifies what can be built where. Within this part of the Act, State Environmental Plans (SEP), Local Environmental Plans (LEP) and Development Control Plans (DCP) are developed. These plans identify in broad terms the controls on any building and development work in a particular area. MBA Environmental Training Course 10 ii) Development Assessment (Part IV) Requires Councils and other determining authorities to assess the suitability or otherwise of all developments in their area. Councils can require: • Statements of Environmental Effects; • Erosion and Sediment Control Plans; • Soil and Water Management Plans; • Waste Minimisation Plans. Most Councils will provide you with a list of what is required when submitting a development application. iii) Development Consent Through the Development Consent powers of the Act, Councils can impose conditions on any development. All Councils will impose conditions of consent. Most use a set of standard conditions as a base and then add extra conditions if they deem it necessary. One of the common standard conditions of consent requires appropriate erosion and sediment control on jobsites. The Standard conditions may also outline what Council’s expect to be included in Erosion and Sediment Control Plans. Not all the conditions of consent are the same for all Councils. Some Councils, for example, require an Erosion and Sediment Control Plan to be submitted with the DA, while others require it to be developed prior to the beginning of construction. MBA Environmental Training Course 11 It is important, therefore, that you read through the conditions of consent for each project. The most common infringement with this law is for “non-compliance with conditions of consent”. iv) Enforcement provisions Councils have a broad range of enforcement provisions they can apply under the Act. They include: • PIN – Section 127A; • CAN – Section 125(1) through Local Court; • Summons – Section 125(1) through Land and Environment Court; • Order 15 – Section 121B, application for local environmental control order – Class 4, Section 727 A detailed explanation of the Environmental Planning and Assessment Act and its requirements are included in Appendix 1 of this manual. 2.3 Protection of Environment Operations Act (1997) (the pollution control law) This Law is built around the concept of “Due Diligence” or “All Reasonable Care”. The DEC has defined due diligence in a number of publications as: • Promoting action to environmental damage. MBA Environmental Training Course prevent or minimise potential 12 • Showing all that could have been reasonably done to prevent an incident from occurring has been done. • Taking all reasonable steps to prevent pollution and protect the environment. • Ensuring that all precaution and control measures are in place and are regularly checked and maintained to minimise the risk of environmental incident. i) Who’s in charge? The PoEO Act makes it clear who’s responsible for enforcing the pollution control laws on building and development sites. The law identifies who is the Appropriate Rogatory Authority (ARA) for each situation. For nearly all building and development sites, the ARA will be the loca Council. That means they are responsible for implementing the requirements of the PoEOAct. The DEC is the ARA for all local Council works, all scheduled works, and the activities of all government agencies. If, for example, you were completing work for the Department of Housing or Landcom, the DEC would be the group responsible for ensuring environmental compliance on those sites. ii) What powers do they have? The PoEO Act gives broad powers to authorised officers to protect their local environments. Authorised officers have, for example, equal powers of entry to the police if they reasonably suspect pollution is occurring at a premises. Any Council officer who visits your site must be provided access to MBA Environmental Training Course 13 the site if they are the ARA. The Council officer must obey all occupational health and safety rules when on that site. Authorised officers also have the power to issue both control notices and Penalty Infringement Notices (PINs). These control notices are a unique feature of the PoEO Act. They have been used very broadly by local Council officers on building and construction sites. The range of notices that can be issued under the Act include: Clean Up Notice • Can be issued when a pollution incident has occurred or is likely to occur. • Can require immediate action. • Must specify a period in which the clean up must be taken. • No right of appeal - ignoring a notice is against the law. • Recipient required to pay a fee for receiving the notice - $320.00. • ARA keeps the money Prevention Notice • Can be issued when an activity is being carried on in an environmentally unsatisfactory manner • Should specify actions required to ensure activity is carried on in an environmentally satisfactory manner. • Cannot require action within 21 days. • Can be appealed. MBA Environmental Training Course 14 • Recipient required to pay a fee for receiving the notice - $320.00. Other Notices • Noise Control Notices - usually technical. Specify noise levels that must be adhered to. • Penalty Infringement Notices - used when people have broken the law. • Compliance Cost Notices - are to enable councils to recover the costs of ensuring compliance with clean up and prevention notices. iii) What are the penalties? There are three tiers of penalty for breaking the law. Tier 3 For minor offences that lead to minimal environmental harm. The penalties for these minor breaches are specified in the law. Penalties are issued as Penalty Infringement Notices or ‘on the spot’ fines. The penalties include: Problem Penalty (individual) Penalty (company) Polluting waters $750 $1500 Causing air pollution $200 $400 Cause emission of noise $750 $1500 Waste dumping $750 $1500 MBA Environmental Training Course 15 Permit land to be unlawfully used as a waste facility $200 $400 Littering (including from vehicles) $750 $1500 Failing to comply with a clean-up notice $750 $1500 Tier 2 The same offences as for Tier 3 but have more serious impact. The penalties for Tier 2 offences are: Individuals: Corporations: maximum $120,000 fine maximum $250,000 fine Tier 1 For incidents that lead to serious environmental harm. The penalties for Tier 1 offences are: Individuals: Maximum $250,000 fine plus maximum of 7 years jail plus clean up costs, frozen assets and damages Corporations: Maximum $1,000,000 fine plus clean up costs, frozen assets and damages. A detailed explanation of the PoEO Act is included as Appendix 1 of this manual. MBA Environmental Training Course 16 2.4 Local Government Act (1997) (as amended 1999) (the catch-all act) Section 8 of this Act requires Councils to “Properly manage, develop, protect, restore, enhance and conserve the environment of the area for which it is responsible”. It is used as a “catch-all” Act by some Councils A detailed explanation of the Local Government Act and its requirements are included in Appendix 1 of this manual. MBA Environmental Training Course 17 Section 3 – Statement of Environmental Effects/Environmental Management Plans MBA Environmental Training Course 18 3.1 Statement of Environmental Effects Many Councils now require a Statement of Environmental Effects, even for minor developments. This usually has to be submitted with the DA. Some Councils provide a framework outlining what should be considered. Most don’t. For developments that are “Designated” under the EP&A Act or developments that in the opinion of the determining authority (usually Council) have the potential to cause significant environmental harm an Environmental Impact Statement (EIS) will be required. If your development requires a detailed Statement of Environmental Effects or an EIS, you should get specialist advice. If the requirement is, however, only for a basic document, you may wish to complete it yourself. The Law, for example, outlines what should be included in a Statement of Environmental Effects. A framework for a basic Statement of Environmental Effects is also provided within this manual. Clause 4 Part 1.2 of Schedule 1 of the EP&A Act declares a Statement of Environmental Effects must indicate the following matters: • The environmental impacts of the development; • How the environmental impacts of the development have been identified; • The steps to be taken to protect the environment or to lessen the expected harm to the environment; • Any matter required to be indicated by any guidelines issued by the Director General for the purposes of this Clause. MBA Environmental Training Course 19 If the DA relates to residential flat development to which State Environmental Planning Policy Number 65 – Design Quality of Residential Flat Development applies, the Statement of Environmental Effects should include: • An explanation of the design in terms of the design quality principles set out in Part 2 of State Environmental Planning Policy No 65 – Design Quality of Residential Flat Development; • Drawings of the proposed development in the context of surrounding development, including the streetscape; • Development compliance with building heights, building height planes, setbacks and building envelope controls (if applicable), marked on plans, sections and elevations; • Drawings of the proposed landscape area, including species selected and material to be used, presented in the context of the proposed building or buildings, and the surrounding development and its context; • If the proposed development is within an area in which the built form is changing, statements of the existing and likely future context; • Photomontages of the proposed development in the context f surrounding development; • A sample board of the proposed materials and colours of the façade; • Detailed selections of the proposed facades; • If appropriate, a model that includes the context. A framework for a basic Statement of Environmental Effects is outlined on the following pages. MBA Environmental Training Course 20 Framework – Statement of Environmental Effects Project description _______________________________________________________ _______________________________________________________ _______________________________________________________ Potential Environmental Impacts Actions to Minimise Impacts Water pollution – from i) Site runoff – erosion and sediment control site runoff, chemical systems will be established on site. They will spills, soils onto include where appropriate: roadways and litter • diversion of upslope water; blowing off site. • minimising extent and duration of land disturbance; • controlling stormwater flows onto, through and from the site; • using erosion control, like mulching, maintenance of onsite vegetation and common entry/exit point, to prevent onsite damage; • using sediment controls, like sediment fences, sandbags, sediment sausages or hay bales to prevent offsite damage, where appropriate; • stabilising disturbed areas progressively; • inspecting and maintaining control measures every day. MBA Environmental Training Course 21 ii) Porta-loo management. Potential impacts from a porta-loo onsite will be minimised by ensuring: • porta-loos positioned where possible overflows will be captured; • porta-loo is serviced in line with industry requirements. iii) Chemical spill. The potential impact of chemicals running off site will be minimised by: • adopting a policy of immediate cleanup of all chemical spills; • ensuring all chemical containers, paint tins and other wastes are disposed of appropriately. iv) Litter management. The impact of litter blowing off site will be minimised through: • ensuring the site is kept clean at all times; • providing appropriate litter bins onsite for trade and personal waste; • ensuring that everyone on site is aware that it is the individual’s responsibility to manage their waste. Waste – site generated i) Waste minimisation. In order to minimise waste or waste created the amount of waste generated on this by employees and building project, we are committed to: subcontractors. • developing a site that incorporates waste operations; • making all subcontractors responsible for their waste; • clearly labelling all waste MBA Environmental Training Course 22 containers; • ensuring that offcuts are used; • ensuring that materials are not damaged or contaminated so that they can be reused; • identifying local markets before setting up a recycling system on site, where appropriate; • establishing and maintaining systems, separating materials onsite for recycling, where appropriate; • reinforcing workers for positive waste minimisation actions; • buying wherever possible materials with minimal packaging; • requiring suppliers to accept their packaging back. Noise – from onsite i) Onsite activities. In order to minimise the activities and vehicle impact of onsite activities, we will: movements on and • build only during the hours offsite. permitted by Council; • maintain all our machinery regularly; • if required, fit noise suppressors; • avoid the use of loud radios ii) On and offsite movement. In order to minimise the impact of on and offsite movement, we will ensure: • all deliveries and loading and unloading of trucks only takes place during the hours permitted by Council; • encourage all of our suppliers to ensure their delivery and MBA Environmental Training Course 23 Hazardous materials – could include soil contamination, air pollution, water pollution, chemical spills and inappropriate waste disposal. loading and unloading equipment is properly maintained; • encourage all of our suppliers to accept the role they have to play minimising noise impact in building and development work i) Onsite activities. In order to minimise the impact of hazardous chemicals we will: • ensure all employees and subcontractors are aware of our policy of immediate cleanup of any spill; • ensure all employees and subcontractors are aware of appropriate spill response procedures; • provide where appropriate spill response equipment, e.g. material to prevent spills flowing into drains and material to absorb spills; • put waste solvents, cleaners and paints in sealed containers for hazardous waste collection in line with Council requirements; • ensure all cleanups of equipment including painting and concreting equipment takes place in line with Council requirements. ii) Asbestos (if appropriate). An asbestos management plan will be developed for the site in line with the requirements of Council and Work Cover. MBA Environmental Training Course 24 Air pollution - from dust, smoke and chemical overspray. Subcontractor impact – from poor onsite practices iii) Lead-based paint (if appropriate). If working with lead-based paint on a renovation or restoration project, all work will be carried out in line with the requirements of Australian standard AS4361.2 “Guide to Lead Paint Management – Part 2: Residential and Commercial Buildings (1998)” i) In order to minimise air pollution on site, we will, where appropriate: • cover stockpiles; • fit dust catchers to equipment; • place sweepings in a bag or cardboard box before putting into a box before putting into a skip to prevent the dust from becoming airborne when the bin is emptied; • when excavating, keep the surface moist to minimise dust; • when sanding or abrasive glassing, use low dust emitting abrasives; • ensure no burning off takes place onsite; • ensure no chemical spraying activity takes place on high wind days. i) In order to minimise the potential environmental impact of subcontractors, we will: • ensure all subcontractors are aware of our organisation’s commitment to minimising environmental impact; • place appropriate signs around the site to remind subcontractors MBA Environmental Training Course 25 of our commitments to protecting local environments; • incorporate, where appropriate, conditions in contracts reminding subcontractors of their individual environmental responsibilities; • distribute, where appropriate, relevant information to subcontractors. Flora and fauna – from i) All vegetation protected by Council orders poor onsite practices will be protected through the use of barriers. The barriers will prevent equipment or subcontractor impact. They will also prevent stockpiles being established underneath protected trees. ii) If some trees are to be removed and others protected, all trees to be removed will be appropriately marked. All onsite employees will be informed of the meaning of those markings. Community – from water pollution, waste, soil contamination, noise and air pollution iii) Through implementing all of the other methods outlined in this statement of environmental effects, the impact on local flora and fauna will be minimal. i) When all of the protection methods outlined in this statement of environmental effects are implemented, environmental impact of this activity on the local community will be minimised. MBA Environmental Training Course 26 3.2 Environmental Management Plans Along with a Statement of Environmental Effects, some Councils will require the builder to develop an Environmental Management Plan (EMP) to be applied during the life of the project. A Project EMP reinforces the commitments made through the Statement of Environmental Effects. It also provides specific details on the controls that will be implemented, and who is responsible for managing those controls. An EMP should be an active document, i.e., it can change during the life of the project as different challenges are identified. Typical contents on an EMP A Typical EMP will include: • Introduction; • Approvals and conditions; • Site plans; • Environmental safeguards; • Allocation of responsibilities; • Incident management procedures; • Reference checks (audit sheets). MBA Environmental Training Course 27 Sample EMP framework EMPs can vary from very straightforward documents of a few pages to detailed descriptions of onsite environmental management that run to several hundred pages. Whereas a Statement of Environmental Effects can include a number of generic statements in relation to potential environmental impact, an EMP must be related specifically to the particular project. A sample EMP has been developed on the following pages to provide an outline of the information that should be included. You should consider preparing basic EMPs yourself. More detailed EMPs may require specialist advice. Environmental Management Plan (EMP) for (description of job) _______________________________________________________ _______________________________________________________ Site supervisor: Name: _______________________ Contact No: _______________ Job Address: ____________________________________________ _______________________________________________________ MBA Environmental Training Course 28 Introduction This section should briefly describe the project including the location and expected duration of the works. In point form it should include a summary of the major environmental issues addressed within the body of the EMP. Approvals and Conditions This part of the EMP should identify the approvals and conditions that have been imposed on the job. It should list, for example, Council’s consent number. It should then refer to the conditions of consent, a copy of which should be attached to this EMP. On some projects it may also be necessary to gain approval from other authorities, including, for example: Sydney Water; Department of Environment and Conservation for works requiring pollution control approvals or licences; • other agencies. • • Most Councils will inform you if you require approval from other agencies. Site Planning Every EMP should have a map that indicates the key environmental features and identifies where environmental safeguards will be implemented. For smaller projects and non-sensitive settings, a sketch map of the site with just essential features will suffice. However, for major projects, the EMP site map should include: typographic features including slopes, waterways, drains, lines, high points; vegetation covering, including any high conservation habited areas, areas of intact native vegetation cover, and lower-grade weed infested areas, MBA Environmental Training Course 29 important landscape items; location of any special items of environmental heritage sensitivity; location of existing areas of disturbance, such as compacted areas; roads and proposed access ways for vehicles and movements of staff and equipment; proposed sites of disturbance such as sites for sheds, workers amenity areas, workers vehicles, equipment stockpiles, etc,; proposed active worksites; location and extent of water pollution control, runoff and silt control devices such as detention bases, silt control fencing, staked, hay bales, bunts, etc. (Erosion and Sediment Control Plans); location of any other devices or equipment associated with environmental safeguards required for the project. Safeguards Safeguards are usually best presented in a table. A sample of a safeguard table is outlined on the following pages: MBA Environmental Training Course 30 Potential Impacts Water pollution Safeguards Responsibility Site supervisor 1. Erosion and sediment control The impact of erosion and sediment loss will be minimised through the implementation of the Erosion and Sediment Control Plan. Details of the plan are included in the site plan associated with this EMP. Along with the installation of erosion and sediment control we will: • check the erosion and sediment controls every day and keep them in good working condition; • inform subcontractors of our commitment to protecting local environments and the role they play in maintaining erosion and sediment control systems; • sweep the road and footpath every day and put soil behind the sediment controls; • ensure all deliveries and movements on and offsite are through the common access point. MBA Environmental Training Course 31 Site supervisor and • ensure all subcontractors are aware of our requirement to clean up all subcontractors. chemical spills immediately; • ensure all concretors, painters and gyprockers use a designated cleaning area for their equipment. Site supervisor 3. Porta-loo management 2. Chemical spills inspect the porta-loo and surrounding area as part of a routine environmental inspection. Site supervisor 4. Litter management • establish designated waste management area; ensure the lids are kept down on skip bins most of the time, but especially overnight; • encourage all subcontractors to play their role in minimising litter onsite. • • MBA Environmental Training Course 32 Waste management We will ensure all of the requirements as outlined in the Waste Management Site supervisor Plan (WMP) (if required) will be implemented. These actions include: • • • Noise establishing designated waste areas onsite; establishing separate bins for landfill waste and recyclable material; encourage the reuse of materials onsite wherever appropriate. We will ensure that we: Site supervisor build only during the hours permitted by Council; maintain all our machinery regularly; if required, fit noise suppressors; avoid the use of loud radios.

Poor Erosion and Sediment Control Planning and management by builders has generated a significant portion of environmental fines received by builders in the past 4-5 years. This is a significant environmental management issue. What harm does a little bit of dirt do, anyway? There are a number of reasons why dirt, soil or sediment needs to be kept out of our waterways. These include 1. Most soils contain some ‘plant food’ or nutrients like phosphorous or nitrogen. These nutrients are water soluble. When water gets on the soil they are dissolved. Plants then draw these dissolved nutrients into their root system. That’s how plants eat. If you then take a bucket full of soil with these water soluble nutrients in it and dump it into a water way then all the water soluble nutrients will dissolve. In every waterway in Australia there are different types of algae. Algae are very simple plants. When there is extra plant food or nutrient in a waterway the algae will eat it and multiply. So when there is a lot of extra nutrient around in a waterway we get algal blooms. Other major sources of nutrient in our waterways include agricultural fertilisers, sewerage overflows and contaminated ground water 2. Soils running off building sites can also be contaminated with paints and other chemicals. These paints and other chemicals can contain heavy metals and other poisons which will harm our waterways. MBA Environmental Training Course 36 3. Sediment washed from building and development sites affect the way our rivers flow by building up on the bottom of the rivers or near the banks. This change to flow patterns in a waterway can affect the biological systems in that waterway. 4. Sediment washed from building sites can block local drains. These drains are designed to carry water away from a particular area. If the drains are blocked local flooding could occur. Clearing blocked drains is also an extra expense for either developers or the local Council rate payers. 5. Increased sediment in waterways can affect the amount of light penetrating in to that waterway which affects the way algae grows and expands. 6. Increased sediment in waterways can also cover the plant and animal communities that live on the bottom of the waterway as well as reduce visibility in the waterway which affects the animal life. Soil can also scratch the gills of fish So there are lots of good reasons for wanting to keep sediment out of our waterways. What is erosion? Erosion is the wearing away of the land by action of rainfall, running water, wind, moving ice or gravitational creep. Soil detachment (erosion) occurs when the erosive forces from raindrop impact and/or flowing water exceed the soil’s resistance. We can minimise erosion on building and development sites by protecting the soil’s surface from the erosive forces of raindrop impact and by conveying water in a non-erosive manner, e.g., through the use of mulch, rock, grass, and slowing the running water down. MBA Environmental Training Course 37 Complete details of the recommended strategies for minimising erosion on building and development sites are included on the following pages. What is sediment and sedimentation? Sediment is the bi-product of erosion, the small soil particles that have been detached. Sedimentation occurs when the transportation of detached soil particles ceases and soil particles settle and fall out suspension. Sediment control measures slow the velocity of water so that soil particles can settle out by gravity or chemically treat sediment laden water to promote settlement of very fine suspended soil particles. You could say that sediment control means to catch and contain sediment before it makes its way into our waterways. How much sediment is lost from building and development sites? It is impossible to identify specifically the amount of sediment that could be lost from a building and development site because of the number of variables involved, including, for example: • area of exposure; • time of exposure; • amount of vegetation on the site; • type of soil; • slope of the site; • amount of water running through the site; • amount of water falling on the site; Most Department of Infrastructure, Planning and Natural Resources and Department of Environment and Conservation studies show, MBA Environmental Training Course 38 however, that sediment from building and development sites is still a significant threat to local waterways all over the state. 4.2 Principles of Erosion and Sediment Control Planning Prepare an Erosion and Sediment Control Plan for your site before works start and submit it with your building application. The plan should show how you will prevent stormwater pollution throughout the construction phase and until the site landscaping has been completed, i.e., the erosion hazard has been reduced to an acceptable level. Different controls might be necessary at different stages over the construction phase as the nature of the site changes, e.g., changing drainage patterns, moving stockpiles to different places, etc. If such changes are likely, these must be shown on the Plan. Installation of Controls Before works start, set up the erosion and sediment controls and install a sign warning everyone of the penalties of pollution (this may be provided by Council). Make sure that all site workers understand their individual responsibilities in preventing pollution. A recommended sequence for setting up controls is: i) ii) iii) iv) establish a single stabilised entry/exit point to the site; install sediment fences along the low side of the site; divert upslope water around the site and, if necessary, stabilise the channels and outlet; clear only those lands which need to be disturbed during the building works. Put up a barrier fence around areas where the vegetation is to not be disturbed; MBA Environmental Training Course 39 v) ensure that any stockpiles are on your land – not the footpath of the next-door neighbour’s land. Where necessary, seek approval from the Council or your neighbour(s) for any offsite stockpiles. Ensure stockpiles have appropriate erosion and sediment controls; vi) install onsite waste receptacles, such as skips or bins, and wind-proof litter receptacles; vii) start building works; viii) install and connect roof downpipes to the stormwater then the roof is completed; and ix) stabilise and exposed earth banks when the building works are completed. Maintenance of Controls All erosion and sediment control works should be checked at least once a week and after each rainfall event to ensure they are working properly. Maintenance might include: i) ii) iii) Removing sediment trapped in sediment fences, catch drains or other areas; Topping up the gravel on the stabilised access; repairing any erosion of drainage channels; and Repairing damage to sediment fences. Remember that the erosion and sediment control works might need to change as the slope and drainage paths change during the development phase. Best practice includes anticipation of the likely risks and being prepared for unusual circumstances, e.g., having spare sediment fence material on the site. Finalisation of Works Ensure that 75% of the site is stabilised before removing the erosion and sediment controls. If landscaping is not completed before handing over the site to the owners, ensure they are aware of their responsibilities under the PoEO Act to prevent pollution. MBA Environmental Training Course 40 Four Basic Principles i) ii) iii) iv) Make sure everyone working on the site understands how important it is not to pollute stormwater. Do not disturb more of the site than you have to. Install erosion and sediment controls before starting work. Maintain your erosion and sediment control works throughout the construction phase. 4.3 Erosion and Sediment Control Plans Nearly every Council across the state is now requiring builders/developers to prepare an Erosion and Sediment Control Plan or a Soil and Water Management Plan showing how they will minimise soil erosion and trap sediment that may be eroded from the site during the construction phase. The complexity of the plan depends upon the nature and scale of any particular development, but especially the amount of land likely to be disturbed. Small scale development such as house extension and the construction of small driveways will not require a plan, but should still be undertaken in a manner which reduces pollution risk. The plan should be a stand alone document consisting of both drawings and a commentary that can be understood easily by all site workers. Outlined on the following pages is a model Erosion and Sediment Control Plan developed by Landcom for a single lot residential building. It contains all lead key components, i.e., the drawing, the commentary and the standard drawings. MBA Environmental Training Course 41 A Model Erosion and Sediment Control Plan The Drawing MBA Environmental Training Course 42 Inclusions for Drawing It is essential that the following information at the very least represented on the drawing: Location of site boundaries and adjoining roads; Appropriate grades and indications of directions of fall; Approximate location of trees and other vegetation showing items for removal or retention (consistent with other plans attached to the application); • Location of site access, proposed roads and other impervious areas, (e.g., parking areas and site facilities), existing and proposed drainage patterns for stormwater discharge points; • North point and scale. • • • The Commentary The Commentary is usually provided with a drawing. The Commentary usually outlines the sequence of events that will take place onsite. Below is a sample commentary provided as a guideline. 1. Site works will not start until the erosion and sediment controls outlined in clauses 2 to 4, below, are installed and functional. 2. The entry/exit of vehicles from the site will be confined to one stabilised point. Sediment or barrier fencing will be used to restrict all vehicular movements to that point. Stabilisation will be achieved by either: - constructing a sealed (e.g. concrete or asphalt) driveway to the street - constructing a stabilised site access following Standard Drawing SD 6-14 or other suitable technique approved by the Council. MBA Environmental Training Course 43 3. Sediment fences (SD 6-8) and barrier fences will be installed as shown on the attached drawing. 4. Topsoil from the work’s area will be stripped and stockpiled (SD 4-1) for later use in landscaping the site. 5. All stockpiles will be placed in the location shown on the ESCP and at least 2 metres clear of all areas of possible areas of concentrated water flow, including driveways. 6. Lands to the rear of the allotment and on the footpath will not be disturbed during works except where essential, e.g. drainage works across the footpath. Where works are necessary, they will be undertaken in such a way to minimise the occurrence of soil erosion, even for short periods. They will be rehabilitated (grassed) as soon as possible. Stockpiles will not be placed on these lands and they will not be used as vehicle parking areas. 7. Approved bins for building waste, concrete and mortar slurries, paints, acid washings and litter will be provided and arrangements made for regular collection and disposal. 8. Guttering will be connected to the stormwater system or the rainwater tank as soon as practicable. 9. Topsoil will be re-spread and all disturbed areas will be stabilized within 20 working days of the completion of works. 10. All erosion and sediment controls will be checked at least weekly and after rain to ensure they are maintained in a fully functional condition. MBA Environmental Training Course 44 Standard Drawings The Soils and Construction (Vol 1) (4th Ed. March 2004) – Managing Urban Stormwater (the Blue Book) is the definitive guide to erosion and sediment control for all types of works. The Blue Book contains standard drawings for the more common features of erosion and sediment control activities. It is not unusual to attach standard drawings to an Erosion and Sediment Control Plan. Outlined on the following pages are the standard drawings included in the sample Landcom document. MBA Environmental Training Course 45 MBA Environmental Training Course 46 MBA Environmental Training Course 47 MBA Environmental Training Course 48 MBA Environmental Training Course 49 4.4 Soil and Water Management Plans Soil and Water Management Plans are often required when a development is large (a common rule of thumb used by planners is for developments over 2500m2) or for sites that have the potential to impact on environmentally significant features of local communities. Soil and Water Management Plans are much more detailed than Erosion and Sediment Control Plans. They are usually prepared by people with expertise in erosion and sediment control. These would include those personnel approved by the Consent Authority or those certified by: the Institution of Engineers, Australia, for engineering and hydrology matters; • the International Erosion Control Association CPESC Program for soil conservation matters; • The Australian Society of Soil Science, for collection or analysis of soil data. • Along with all the information provided in an Erosion and Sediment Control Plan, the “Managing Urban Stormwater – Soils and Construction, Vol. 1 (March 2004) (the Blue Book) suggests Soil and Water Management Plans should also include: • the location of lots, public open space, stormwater drainage systems, schools, shopping community centres; • the location of land designated or zoned for special used; • the location and general diagrammatic representations of all necessary erosion and sediment control BMP; • the location and engineering details of supporting design calculations for all necessary sediment bases; MBA Environmental Training Course 50 • location of basic details of any other facilities proposed to be included as part of the development, works such as constructed work lands, gross pollutant traps, or trash racks or trash collection separator units. The plan should also specify the scale, type, operation and maintenance of all soil and water management devices in the soil and water management program. 4.5 What Council Personnel May Look for on Erosion and Sediment Control Plans/Soil and Water Management Plans Outlined below is a table that may be considered by Councils for reviewing Erosion and Sediment Control and Soil and Water Management Plans. This may provide some useful guidance to the sort of matters that should be included in Plans.

Sediment control measures aim to capture eroded soil particles by either slowing the velocity of water flow so that soil particles can settle out by gravity or by chemical treatment to flocculate suspended soil particles. As sediment is only generated when soil erosion occurs, installation or construction of erosion control measures should be the first priority. Erosion control is also easier and cheaper than sediment control. Although the list of measures is comprehensive it is not exhaustive. New erosion and sediment control technologies are being developed all the time. The measures described are proven and are known to work if designed and implemented correctly. Permanent erosion and sediment control measures require formal design. Failure to undertake formal design in most instances is an unacceptable risk. Erosion and sediment control is not rocket science, however, inappropriate or poorly designed or installed control measures can often cause more problems than they solve. When in doubt seek independent expert advice. Many self proclaimed erosion and sediment control experts are product suppliers and therefore have a vested interest in promoting their product over what is right for the MBA Environmental Training Course 57 sight. Be aware of this when seeking erosion and sediment control advice from salesmen. Expert advice can be obtained from Certified Professionals in Erosion and Sediment Control (CPESC) through the International Erosion Control Association (Australasia) (IECA). The Government guideline “Managing Urban Stormwater – Soils & Construction” or also known as the “Blue Book” is a great reference book that can assist with selection of products. EROSION & SEDIMENT CONTROL MEASURES Surface Roughening – Track Walking Description: A technique that leaves the soil surface in a roughened state to increase water infiltration, decrease and slow down run-off and to encourage sediment retention and vegetation establishment. It also discourages vehicular traffic across the soil surface. Application: For any slope that is safe for the use of machinery. For track-walking maximum 1(v):2(h). Installation Aspects: Upslope run-off should be diverted away from the slope to be treated. Problems: Upslope stormwater is not diverted around area and rill erosion will occur. Turf MBA Environmental Training Course 58 Description: Refers to a layer of topsoil and grass harvested from the field by specialist machinery. Rolls can be supplied up to 5 m wide by 9m long. Reinforced turf in similar to conventional turf except that grass is grown through an artificial 2 dimensional polypropylene grid to provide additional strength. Application: Turf and Reinforced Turf can be used in both sheet flow and concentrated flow situation to provide erosion protection. It is often used as a “softer” alternative to “hard” channel linings such as rock and concrete in urban situations. Design/Construction Aspects: Turf is only capable of withstanding relatively low flow velocities. Reinforced Turf can withstand flow velocities a lot higher than turf. Deposited sediment can kill turf. For this reason upstream erosion protection and sediment detention measures must be installed before the turf can be placed. As turf and reinforced turf rely on the grass root system for strength, the substrate on to which the turf is being placed must be suitable for vegetation establishment. The edges of the turf/reinforced turf must be installed flush with the existing soil surface so that erosion along the turf/soil interface does not occur. Problems: Deposited sediment can kill turf. Due to the way reinforced turf is grown, the roots can become “root bound” and therefore the time for the roots to bind into the soil surface is increased thus increasing the erosion/failure potential. Turf must be watered until adequately established. Erosion Mats and Blankets MBA Environmental Training Course 59 Description: A rolled matt or blanket made from jute, coconut fibre, wool, nylon and poly-propylene that is placed on the soil surface to protect it from raindrop impacts and low velocity sheet and concentrated flows. Application: Erosion control blankets are used on batters and embankments and other sheet flow environments to protect the soil from erosion and promote vegetation. Blankets are generally temporary measures and are designed to biodegrade. Typically these products are made from wood fibre, wool and jute. Erosion control mats are designed to be used in concentrated flow environments and are therefore made from more durable materials such as jute, coconut fibre, nylon and poly-propylene. Design/Construction Aspects: Due to the vast range of proprietary products available, independent advice should be sought on the appropriate matt/blanket for a particular situation. Manufactures supply product specifications and installation guidelines. Problems: When blankets are placed in concentrated flow areas. A blanket is designed to cover the ground from raindrop impact and a matt is a heavier product designed for concentrated flow. Remember B is for blanket as in Batter. Rock Check Dams Description: A small temporary rock weir structure. Can also be constructed from sandbags and logs. Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as MBA Environmental Training Course 60 perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. The middle of the Check Dam must have a spillway to stop water running around the ends. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. Surface Mulching Description: Mulching is the placement of a protective cover over the soil surface to protect it from the erosive effects of raindrop impact and shallow sheet flows. Common mulch materials include wood chip, straw, wood fibre, paper pulp, bagasse, brush matt and bitumen emulsion. Application: The type of mulch to be used in dependant on the type of environment to be protected, climatic conditions, location and available mulch material. Design/Construction Aspects: Common to most situations where mulches are to be used, divert flows away from the area to be protected. The application of mulch material should be even and uniform. MBA Environmental Training Course 61 Problems: Mulch washed away due to failure to divert flows away from mulched area. Erosion due to insufficient quantity of mulch or tackifier. Weed infestation due to weed contaminated mulch (eg hay instead of clean straw). Vegetation Description: For erosion purposes vegetation includes native and introduced grasses, ground covers, shrubs and trees. Application: Any erosion control program will benefit from temporary and permanent vegetation covers. The above ground vegetative material provides protection from raindrop impact slows flow velocities and traps eroded soil particles. Roots help bind the soil surface thus minimising erosion. Problems: Weed infestation due to the use of contaminated seed. Difficulty in maintaining an adequate vegetative cover due to climatic/soil constraints. Sediment Fence Description: A sediment fence is a temporary barrier of permeable geotextile, partially installed in a trench and supported by posts. Design/Construction Aspects: Not to be used in concentrated flow. Silt fence should be installed on the contour with the ends turned up so that the turn-up ground level is equal to the top fabric level at its lowest point. MBA Environmental Training Course 62 Sediment fence must be anchored in a 150mm deep compacted backfilled trench. The sediment fence posts must be on the downslope side of the fabric otherwise the fabric will come away from the peg when put under pressure. Problems: Not installed with a turnback at either end causing water to run around the ends. Not trenched in deep enough causing fabric to pull out of the ground. Not compacting the trench after installation causing water to tunnel under the sediment control fence. (You only need to compact the ground with you boots no need for a compactor to be brought in.) Check Dams Description: A small temporary rock weir structure. Can also be constructed from sandbags and logs. Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. Straw Bales MBA Environmental Training Course 63 Description: A small temporary dam. Straw bales are suitable for low flows of water. It is only recommended that these be used in limited applications. They maybe used to reduce the flow velocity of water. Design/Construction Aspects Not to be used in concentrated flow. Straw bales should be installed on the contour with the ends turned up so that the turn-up ground level is equal to the top of the middle bale. Straw bales should be anchored into the ground 100mm with a star picket post to secure. The minimum number of straw bales to be used is four. You can not make a dam with one or two straw bales. Problems: Erosion around the edge of the straw bale dam due to insufficient spillway depth and insufficient number of bales used. Remember minimum number of bales to be used is four. Erosion immediately downslope of the straw bale dam to insufficient rock protection. Sand Bags Description: Sand bags are used to make a temporary sediment trap and are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally do not have an outlet they form a pond. Application: Their function is to trap coarse sediments in both concentrated and sheet flow situations. They should be located immediately downstream of disturbed areas. MBA Environmental Training Course 64 Design/Construction Aspects: Sediment traps can be formed by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include not building the structure large enough to contain the amount of water that will be washed from the site. Difficulty in cleaning out sediment, due to poor location and design. Sediment Traps Description: Sediment traps are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally consist of a stable inlet and outlet, and some form of pond. Application: Their function is to trap coarse sediments in concentrated flow situations. They should be located immediately downstream of disturbed areas. Design/Construction Aspects: Formal design of sediment traps is required. Sediment traps can be formed by excavating an earthen pond, or by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include inlet and outlet erosion due to inadequate erosion protection. Difficulty in cleaning out sediment due to poor location and design. MBA Environmental Training Course 65 4.7 Common Erosion and Sediment Control Problems on Building and development sites Typical Problems Include… • No systems or tools at all; • Right systems of tools but in the wrong place or poorly fitted; • Wrong systems; • Poorly maintained systems. • Sediment fence not dug in 150mm; • Stakes in sediment fence too wide apart; • Sediment fence constructed across the contour, no turn backs; • Sediment fence fitted in areas of concentrated flow; • No stabilised entry; • No upslope drain controls; • No diversion around stockpiles; • Stockpiles above 2m high; • Downpipes not connected as soon as roof is completed; • Hay bales used in the wrong place; • Removal of all vegetation from site when it’s not necessary; MBA Environmental Training Course 66 • Removal if potential filter strips, i.e. bushland or turf, before any construction occurs; • Poor management of subcontractors on site. MBA Environmental Training Course 67 Section 5 – Waste Management MBA Environmental Training Course 68 Waste disposal costs have increased dramatically in the last few years. That trend is certain to continue. Recent studies have suggested about 10-15kg of waste is produced per square metre (gross floor area) in building a typical brick veneer house in Sydney. The largest waste components are timber, plaster, board and bricks. The amount of construction waste has become a concern for three main reasons: most of the resources used to make construction materials are finite and will run out one day – recent levels of waste production are unsustainable; • many landfill sites in or near metropolitan areas (where most building occurs) are full or nearly full. Creating new ones is a waste of productive land; • proper landfilling to avoid environmental consequences is very expensive. • In order to encourage the building and construction sector to reduce their waste, the Sydney Regional Organisations of Councils in 1996 produced a “Waste Not Development Control Plan” (DCP). The purpose of this DCP was to ensure a responsible approach to waste management in the construction and demolition industry. Around 60% of Councils in the greater Sydney, Hunter and Illawarra areas have formally adopted the Waste Not DCP. This means that many Councils will require builders and developers to prepare a Waste Minimisation Plan as part of their approval or consent process. The Waste Not guidelines included a framework Waste Management Plan. MBA Environmental Training Course 69 Outlined on the following pages is a copy of that framework. Examples have been included within that framework to provide guidance to builders on how Councils will expect it to be completed. These examples have only been provided in Sections 1 and 2, which are the parts that builders and developers will mostly be required to complete. MBA Environmental Training Course 70 Waste Management Plan Demolition, Construction and Use of Premises The applicable sections of this table must be completed and submitted with your Development Application. Completing this table will assist you in identifying the type of waste that will be generated and in advising Council now you intend to reuse, recycle or dispose of the waste. The information provided on the form (and on your plans) will be assessed against the objectives of the DCP.

Perhaps the first thing that applicants should consider is whether it is possible to re-use existing buildings, or parts thereof, for the proposed use. With careful onsite sorting and storage and by staging work programs it is possible to re-use many materials, either on-site or off-site. In other words, Council is seeking to move from the attitude of straight demolition to a process of selected deconstruction i.e. from “trashing the building”, to “total reuse and recycling both off-site and on-site”. This could require a number of colour-coded or clearly labelled bins on-site (rather than one size fits all). Applicants should demonstrate project management that seeks to: re-use excavated material on-site and dispose of any excess to an approved site; process and re-use green waste as mulch in landscaping on-site or taken off-site for processing; re-use bricks, tiles and concrete on-site as appropriate, or recycle offsite; re-use framing timber on-site or recycled elsewhere; recycle windows, doors and joinery off-site; recycle plumbing, fittings and metal elements off-site; dispose of all asbestos, hazardous and/or intractable wastes in accordance with WorkCover Authority and EPA requirements; MBA Environmental Training Course 72 indicate the location of on-site storage facilities for material to be reused on-site and a separate storage area nominated for materials to be recycled off-site; and nominate the destination and transportation routes of all materials to be either recycled or disposed of off-site.

MBA Environmental Training Course 75 The following table is to be completed by applicants proposing any demolition work. The following details are to be shown on your plans • location of on-site storage space for: i) materials for re-use on-site; ii) container for materials to be recycled off-site; and iii) container for materials to be sent for disposal/landfill. • vehicle access to the site and to the above storage and container areas. MBA Environmental Training Course 76 Please explain: • How will waste be separated and/or stored onsite for reuse and recycling? • How will site operations be managed to ensure minimal waste creation and maximum reuse and recycling? {e.g. Staff training, selected deconstruction v. straight demolition, waste management requirements stipulated in contracts with sub-contractors, ongoing checks by site supervisors, separate area set aside for sorted wastes, clear signage of waste areas etc}. Note: Details of the site area to be used for on-site separation, treatment and storage (including weather protection) should be provided on plan drawings accompanying your application. MBA Environmental Training Course 77 Stage 2 - Construction Potential for Waste Minimisation During Construction Stage You should consider the following measures that may also save resources and minimise waste at the construction stage. • Purchasing Policy – considering measures such as ordering the right quantities of materials and prefabrication of materials where possible; • Reusing formwork ; • Minimising site disturbance, limiting unnecessary excavation; • Careful source separation of off-cuts to facilitate re-use, resale or efficient recycling; • Co-ordination/sequencing of various trades. How do I Estimate Quantities of Waste? There are many simple techniques you can use to help you estimate volumes of construction and demolition waste. The information below can be used as a guide by builders, developers & homeowners when completing a waste management plan: To Estimate Your Waste: a. Quantify materials for the project b. Use margin normally allowed in ordering c. Copy these amount of waste into you waste management plan MBA Environmental Training Course 78 When estimating your waste the following percentages are building “rule of thumb” and relate to renovations and small home building: Material Waste as a Percent of the Total Material Ordered 5-7% 5-20% 3-5% 5-10% 2-5% Timber Plasterboard Concrete Bricks Tiles Converting Volume into Tonnes – A Guide for Conversion Timber: Concrete: Bricks: Tiles: Steel: = 0.5 tone per m3 = 2.4 tone per m3 = 1.0 tone per m3 = 0.75 tone per m3 = 2-4 tone per m3 To improve your “guesstimates” and provide more reliable figures: • • • • • Compare your projected waste quantities with actual waste produced Conduct waste audits of current projects Note waste generated and disposal methods Look at past waste disposal receipts Record this information to help you estimate future waste management plans On a waste management plan, amounts of waste may be stated in - m2 or m3 or tonnes (T).

Note: Details of site area to be used for on-site separation, treatment and storage (including weather protection) must be provided on plan drawings accompanying your application. MBA Environmental Training Course 82 Stage Three – Design Facilities The following details should be shown on your plans: • Location of temporary waste storage space within each dwelling unit; • Location of external Waste Storage and Recycling Area(s), per dwelling unit or located communally on site. In the latter case this could be a Garbage and Recycling room or bin bay; • Details of design for Waste and Recycling Storage Area(s) / Facilities and any conveyance or volume reduction equipment; • Location of communal composting area; and • Access for waste collection vehicles. Every building shall be provided with a Waste Storage and Recycling Area that is flexible in size and layout to cater for future changes in use. The size is to be calculated on the basis of waste generation rates and proposed bin sizes.

MBA Environmental Training Course 84 Stage 4 – Ongoing Management: Final Use/Occupation of Site This section will enable you to describe how you intend to ensure adequate ongoing management of waste on-site when final occupation takes place (eg. lease conditions, care-taker/manager on site). Describe how you intend to ensure adequate on-going management of waste on-site (eg. individual residents/occupants are responsible, body corporate, caretaker or manager on site, lease conditions etc.). MBA Environmental Training Course 85 For a copy of the Western Sydney Recycling Directory or for assistance with completing your waste management plan, please contact Council’s Waste Project Officer on Ph (02) 9843 – 0505. Thank you for the information. MBA Environmental Training Course 86 5.3 Who Takes the Waste? Many Councils have produced local construction and demolition waste recycling directories. The DEC has also produced a construction and demolition waste recycling directory. A copy is included as Appendix 2 of this manual. If you can’t find what you need in the directory, you should approach the local Council and see if they can provide you with some advice or support. You may also wish to call the Pollution Line: 131 555. They may also be able to let you know who collects and disposes of different types of construction and demolition waste in your area. 5.4 Encouraging Waste Minimisation Onsite Waste minimisation can be achieved if we follow the key principles of: • reducing the use of materials; • reusing materials wherever we can; • recycling whatever is appropriate; • only disposing of what’s left. Getting everyone onsite to play their part in waste minimisation can, however, be very challenging. In order to achieve this, there needs to be, in some organisations and in some trades, a significant cultural shift. In order to encourage that cultural shift, some of the strategies used by builders and developers have included: MBA Environmental Training Course 87 • making all subcontractors responsible for their waste; • clearly labelling all waste containers; • training all workers to practice waste minimisation; • ensuring that offcuts are used; • ensuring that materials are not damaged or contaminated so they cannot be reused; • setting up systems to separate materials onsite for recycling; • giving positive feedback to workers; • requiring suppliers to accept their packaging back, particularly with large white goods; • buying materials with minimal packaging; • putting up signs telling workers of collecting and recycling goals. The Master Builder’s Association also has an excellent video “Not Another ?*!!*? Form!”. MBA Environmental Training Course 88 Section 6 – Noise, Hazardous Chemicals and Air Pollution Management MBA Environmental Training Course 89 6.1 Noise Management You can minimise the noise generated by your building and construction work through: • reducing machinery noise by fitting noise suppressors and maintaining the machinery regularly; • building only during the hours permitted by Council. Legislation limits the amount of noise permitted and when it is permitted; • scheduling noisy trucks so as to minimise annoyance to neighbours; • avoiding the use of loud radios; • wearing earplugs to protect your hearing. The broad requirements of the noise control laws are outlined in the “Neighbourhood Noise” leaflet, which is included as Appendix 3 of this manual. 6.2 Hazardous Chemical Management Most materials can be hazardous or dangerous to the environment if handled or stored inappropriately. Many hazardous substances such as chemical products are commonly used on building sites. Some hazardous substances, such as lead paint and asbestos, may have been used in the past. All require special precautionary practices to protect both the environment and your health. Builders must also have in place practices and procedures to prevent accidental leaks and spills of potentially hazardous materials. Correct MBA Environmental Training Course 90 handling helps prevent pollution of the ground, stormwater drains and local waterways. Material Safety Datasheets (MSDS) Any organisation using or storing chemicals is required to have Material Safety Datasheet (MSDS) for these chemicals onsite. MSDS outline the procedures for dealing with spills of that chemical, the disposal of that chemical and its container when it is utilised and how to deal with any poisonings that may occur. Site supervisors must know where the MSDS are stored onsite and the requirements of that sheet, in particular in relation to poisoning and spill response. Ground Contamination Solvents, paints and other chemicals must not be allowed to soak into the ground. Contaminants can enter the ground water and eventually reach rivers or our drinking water. They can also make sites unusable. Asbestos Work Cover has very clear guidelines for checking, managing and removing asbestos. It is imperative that your site supervisors are aware of those guidelines and their requirements. Disposal of asbestos also requires special treatment. Waste Service NSW ((02) 9934 7000) can provide advice on appropriate disposal techniques for asbestos. MBA Environmental Training Course 91 Most recycling directories will also list organisations that are licensed to take asbestos. Lead Paint Lead paint was used extensively in houses and buildings until 1970. If you are involved in renovating or demolishing a building built before then, you should be aware of the potential impacts of lead. Lead dust from old paint, ceiling cavities or wall cavities can be a major hazard. If you are dealing with lead paint, some basic strategies should be considered. These are outlined in “Lead Safe: A Renovators Guide to the Dangers of Lead” (EPA 1998) and “Australian Standard AS436 1.2 “Guide to Lead Paint Management Part 2: Residential and Commercial Buildings” (1998). Managing Chemicals Onsite It is important that you store paints, stains and other chemicals in a lock-up cabinet that has an impervious floor and is bunded so that it will hold at least 110% of the contents of the largest container stored in the area. Put waste solvents, cleaners and paints in sealed containers for hazardous waste collection. Find out from your local Council where and how to dispose of hazardous materials safely. Take care not to spill materials such as solvents, paints and other chemicals. Clean up all spills immediately to prevent contamination of the ground and stormwater. MBA Environmental Training Course 92 Emergency Response Procedures As a part of your due diligence responsibilities it is essential that you develop emergency response procedures. The basic requirements of the spill procedure are: • stop the source of the spill immediately if it is safe to do so; • contain the spill and control its flow; • stop the spill from entering any stormwater drains by blocking the drain inlets; • clean up the spill promptly by following the relevant material safety datasheet (MSDS). It is important to clean up all spills quickly, even small ones, as they can easily flow into stormwater drains or be washed in by the rain. You should include a copy of your emergency spill procedure with your Environmental Management Plan. It is also essential that all your staff members are aware of your organisation’s spill response requirements. Signs around the building site should also remind subcontractors that it is a requirement of your organisation that all spills be cleaned up immediately. 6.3 Air Pollution Management Some of the activities on your site can affect local air quality and also contribute to the bigger problems of urban air pollution. Air pollution can be caused by dust, fumes, gases or smoke coming from your activities or from the equipment you use. MBA Environmental Training Course 93 Reduce wind-blown dust from your site. Dust can cause health problems for workers and neighbours. You should: • Cover materials and stockpiles. • Fit dust catchers to equipment. • Place sweepings in a bag or cardboard box before putting it into a skip to prevent dust from becoming airborne when the bin is emptied. • Put up dust screens around the edges of the site. • Wear facemasks and respirators to protect your health when creating dust. • If you are sanding or abrasive-blasting use low-dust-emitting abrasives. Consider wet, hydro or vacuum blasting as alternative to dry blasting. It is generally against the law to burn off. Place all rubbish that cannot be reused or recycled in your waste disposal skip. Weld in well ventilated areas, as the fumes can cause metal fume fever and severe headaches, particularly if the galvanising zinc has not been removed first. MBA Environmental Training Course 94 Section 7 – Managing Subcontractors MBA Environmental Training Course 95 Plumbers, electricians, gyprockers, excavators, landscapers, bricklayers and delivery drivers are just some of the subcontractors who move on and off building and development sites on a regular basis. The challenge for the builder and developer is to ensure each of the subcontractors comply with environmental requirements while they are working onsite. Ultimately the builder or developer is responsible for the site and for the most part the builder or developer is held responsible for any environmental infringements that occur onsite. A number of Councils are indicating that if they identify poor practice on the part of subcontractors they will, however, act in the first instance against the subcontractor, particularly if the builder or developer con demonstrate due diligence in the management of that site. 7.1 Due Diligence with Subcontractors In order to ensure subcontractors are managed with due diligence, you need to make sure all contractors are: • aware of their environmental responsibilities when on your site; • aware of environmental systems that have been put in place to minimise environmental impact, e.g., designated waste areas, stockpile areas, sediment and erosion control systems and waste management systems; • understanding of the consequences of breaking environmental laws. MBA Environmental Training Course 96 7.2 Contract Conditions A number of builders and developers have begun inserting environmental conditions into their subcontracts. Essentially the builders and developers establish a set of site rules that are listed in the subcontract and the subcontractor is asked to sign that they understand and acknowledge the rules and will keep to them. A sample of those rules are outlined below. Site Rules Set out below is a list of requirements you are expected to maintain at all times while working on (name of company) building sites. 1. The sediment barriers are to remain intact. If it is necessary for you to remove the barrier, it must be reinstated before you leave that day. When reinstating the barrier it must be trenched into the ground at least 150mm. 2. All building rubbish and waste is to be placed in the designated area each day. 3. All food scraps, lunch wrappings, newspapers and drink containers are to be taken off site each day and disposed of responsibly. 4. Do not wash within 3 metres of the street gutter. Where it is necessary to wash out you must ensure that waste water does not travel towards the street gutter. 5. Where it is necessary for your vehicle to leave the roadway to unload any material or tools you must use the stabilised (road base) access entry point only. MBA Environmental Training Course 97 6. Any mud or dirt on the roadway or on the street gutter must be removed and swept clean before you leave that day. 7. Be aware of Councils’ allowable working hours for building sites when either working on site or delivering materials. 8. Be considerate of adjoining neighbours when having radios playing onsite. You and others in your business should be aware of the law and penalties and take all reasonable care not to harm the environment. You need to be aware that the Department of Environment and Conservation (DEC) as well as local Council inspectors are empowered to monitor the industry and issue penalty infringement notices. Under the PoEO Act, on-the-spot fines of $1500 will be imposed. On top of this fine you may also be charged a $320 administration fee. The law does not recognise: • whether or not the site is difficult; • problems that might be encountered in implementing the plan; • whether or not you are familiar with good soil and water standards. If you plan to insert these types of conditions into your subcontracts, you should first of all seek appropriate legal advice. A number of builders have found them very handy in focusing the attention of subcontractors on their responsibilities and to encourage them to support the builder and developer’s environmental management systems. MBA Environmental Training Course 98 7.3 Subcontractor Education A number of educational resources can be utilised to make sure subcontractors are aware of their responsibilities. These include: • site inductions – most builders and developers provide a site induction to their subcontractors in order to meet the requirements of the OH&S legislation. Site environmental management requirements should be incorporated into those site inductions; • onsite signage – many Councils these days are requiring builders to display environmental warning signs on their erosion and sediment control systems. Builders may consider bringing the intent of those signs to the notice of their subcontractors. Some builders have also developed other signs they place around the site to support their waste, recycling and their chemical spill response practices onsite; • leaflets – a number of Councils have prepared leaflets targeting particular trades. A sample of those leaflets are included as Appendix 4 of this document. You may wish to include copies of these leaflets with your contracts. 7.4 Onsite Audits You need to conduct regular basic audit checks of your sites as part of your due diligence responsibilities (see Section 8 for more details). A number of companies are now developing formal onsite “Corrective Action” notices that are served on the subcontractor. Within that Corrective Action notice you should identify: • what the problem is; MBA Environmental Training Course 99 • when you want it fixed (e.g., immediately/within the week/close down work area) • who is responsible for implementing the requested changes; • how they will report back when those changes have been implemented. Some local courts have found diary notes to be sufficient while others have required a more formal notification to be delivered to the subcontractor. 7.5 Conclusion Subcontractors are a critical part of building and development work. They can be a challenging group to manage. If, however, you work with good quality subcontractors and explain to them your commitment to environmental protection and the benefits that will be generated for them as well, and the possible fines that could be incurred if they don’t take any notice of the laws, you should be able to encourage their support. MBA Environmental Training Course 100 Section 8 – Self Audits MBA Environmental Training Course 101 One of the key components of due diligence is regular checks or audits of your onsite environmental management systems. Council enforcement personnel regularly express concern about builders who put a great deal of time, money and effort into establishing excellent environmental management systems at the beginning of a project only to see them fall apart as the project progresses. These builders have already spent the money they need to on hardware. Simple maintenance would make sure they would be meeting their environmental responsibilities and therefore not be fined. 8.1 How Often Should Systems be Checked? Erosion and sediment control systems should be checked at the end of every day. Chemical storage, waste recycling and designated cleaning areas should also be checked on a regular basis. 8.2 What Should you Look For? In order to guide builders and developers identifying what should be looked for on a building site, we have included a sample checklist that is used for Council officers for visiting building sites. This is outlined on the following pages.

It’s not just about environmental protection or management. It’s about the social and economic wellbeing of our communities. Sustainability as a philosophy is gaining more and more support throughout the professional and general community. The NSW Government’s “Our Environment – It’s A Living Thing” is all about sustainable living and sustainable lifestyles. Most professional building and development organisations including the Master Builder’s Association have made policy commitments to the promotion of sustainable management of building and development sites through all phases. A number of industry awards are also recognising building and development companies for their sustainable management practices. 9.1 Sustainability Development Sector and the Building and Sustainability in the building and development sector is all about: • planning; • design; • efficient resource use at all stages; • ongoing use. MBA Environmental Training Course 110 Over the past few years, a number of practives that were once considered different in the bilding sect6or have now become mainstream. These include: • use of solar power; • water reuse; • energy efficient appliances; • water sensitive urban design on major developments; • waste minimisation initiatives. 9.2 Encouraging Sustainability The most effective way of encouraging sustainable practices in the building and development sector is to get all the professions in that sector working together. Certainly builders can implement sustainable practices during the demolition and construction of a project. These practices will have far more impact, however, if they are being implemented through a sustainable design and on a sustainably managed piece of land. It is important, therefore, for builders and developers to talk to their designers and their development colleagues. Talk to your suppliers, talk to your customers. Sustainable management is the way to a better future for all of us. It is up to all of us, however, to find out what role we can play in the implementation of our sustainable management program. MBA Environmental Training Course 111 9.3 More Information Two very useful websites to start with are: • DEC website – www.environment.nse.gov.au • Department of Energy, Utilities and Sustainability (DEUS) – www.deus.nsw.gov.au MBA Environmental Training Course 112 Appendix 1 - An Overview of the Environmental Laws relating to the management of erosion and sediment control on Council and other building and development sites MBA Environmental Training Course 113 There are general laws that outline Councils broad environmental responsibilities and specific laws that outline Council operational and management enforcement responsibilities. Outlined below is the summary of the requirements of those laws. The Local Government Act 1993 (as amended 1997) The Local Government Act outlines overarching responsibilities for Council in terms of ensuring the local environment is effectively managed. The first stated purpose of the NSW Local Government Act (section 7a) is ‘to provide the legal framework for an effective, efficient environmentally responsible open system of local government in NSW.’ Another stated purpose of the Act (section 7e) is to ‘require Council’s, Councillors and Council employees to have regard to the principal of ecologically sustainable development in carrying out their responsibilities.’ The Local Government Act 1993 (as amended 1997) (section 8) sets out the charter of a local Councils in NSW and includes the requirements for a Council to ‘properly manage, develop, protect, restore, enhance and conserve the environment of the area for which it is responsible.’ Section 402 of The Local Government Act (1997) sets out the contents of a Council’s draft management plan and also requires that the statement of principal activities must include particulars with respect to ‘activities to properly manage, develop, protect, restore and conserve the environment.’ So the Local Government Act sets a broad agenda for Council. Specific links could then be made from this act to Councils erosion and sediment control responsibilities in all areas of activity. It should be noted that Council does have power to issue enforcement notices under Section 124 of the Local Government Act but the general view of Councils identified through the research was that the Protection of the Environment Operations Act (1997) was a much more useful and flexible enforcement tool. Protection of the Environment Operations Act (1997) MBA Environmental Training Course 114 This is the main environmental protection law in NSW. This law can be used by the Department of Environment and Conservation (DEC (NSW)) to deal with inappropriate practice on Council sites. It can also be used by Council to deal with inappropriate practice on building and development sites in their area. This Act requires any individual or organisation carrying out any activity to ensure that activity is completed with ‘due diligence’ or ‘all reasonable care’ in order to ensure the environment is protected. The DEC (NSW) has indicated in a number of publications that ‘due diligence’ means: • taking all reasonable steps to prevent pollution and protect the environment • promoting action to prevent or minimise potential environmental damage • showing that all that could have reasonably been done to prevent an incident from occurring has been done • ensuring that all precautionary and control measures are in place and are regularly checked and maintained to minimise the risk of an environmental incident. As well as the broad due diligence requirements, the Act also provides the DEC (NSW) and Council with some specific enforcement tools. These tools include a) Clean Up Notices (Section 91). Under Section 91 of the Act, authorised officers do not have to wait for the environment to be harmed before they can take action. Authorised officers from both the DEC (NSW) and Council can issue Clean Up Notices at sites where they are of the view that an incident has occurred or is likely to occur. The Clean Up Notice is a direction notice and not a penalty notice in that its purpose is to direct the person or organisation receiving it to take action in order to minimise environmental harm. The Notice must outline the actions required in broad terms and must specify a deadline for those actions to be taken. A Clean Up Notice can require immediate action. A Clean Up Notice can also be served verbally but must be followed up in writing within 72 hours. MBA Environmental Training Course 115 Clean Up Notices are also not appealable and so any person receiving a Clean Up Notice must do what it says. If a person receiving a Clean Up Notice decides not to take the nominated actions, they can receive a Penalty Infringement Notice (PIN) for a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 000 for individuals and $250 000 for corporations. Councils and the DEC (NSW) can also charge an administrative fee of $320 for the issue of a Clean Up Notice. Failure to pay this fee can also attract a fine for up to $1000. Councils and the DEC (NSW) can decide not to impose the fee. Clean Up Notices appear to be the most widely used enforcement tool for minimising erosion and sediment loss on building and development sites. Clean Up Notices can be used for example on building sites with no or poorly maintained erosion and sediment control in place even if it’s not raining. Councils have also used Clean Up Notices to require developers to sweep the streets around their development sites at the end of every day. There is also authority within this Act for Councils to take the clean up action themselves if the person receiving the notice chooses not to within the designated time. Councils can recover the costs associated with completing this work from the person or organisation who received the original notice (see Part C – Compliance Cost Notices). b) Prevention Notices (Section 96). Prevention Notices are for more systematic environmental challenges. They are used in response to ‘environmentally unsatisfactory behaviour.’ Prevention Notices are appealable and so cannot require action within 21 days. A Prevention Notice also outlines the actions a person is required to take and provides a deadline for those actions to be completed. If a Prevention Notice is not appealed or upheld on appeal and a person chooses not to carry out the actions outlined in the prevention notice it is a breach of the POEO Act and will attract a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 000 for individuals and $250 000 for incorporations. MBA Environmental Training Course 116 The DEC (NSW) and Council can also charge an administrative fee of $320 for serving the notice. Given the need to allow 21 days for any action to be implemented, it is unlikely that many Prevention Notices will be used to encourage more effective erosion and sediment control on Council or privately operated building and development sites. c) Compliance Cost Notice (Section 104) Compliance Cost Notices enable Councils to recover the costs of ensuring compliance with Clean Up and Prevention Notices. These costs can include the cost of monitoring action taken under a Clean Up or Prevention Notice and the cost of a Council doing a clean up voluntarily or under direction from the DEC (NSW). For example if Council issues a Clean Up Notice to a developer requiring them to sweep the streets at the end of every day and upon investigation finds this action has not been taken, and Council is within their rights to bring the Councils street sweeper to the site in order to carry out the Clean up Action. The cost of the street sweeper as well as the cost associated with the Council officer visiting the site can all be included in a Compliance Cost Notice. Council is also within their rights to fine the developer for non compliance with a Clean Up Notice. d) Penalty Infringement Notices (PIN). (A range of Sections) Most erosion and sediment control breaches will be dealt with through the issue of a Penalty Infringement Notice. The Penalty Infringement Notice operates like an ‘on the spot fine.’ The fines attached to Penalty Infringement Notices are set in the Act. A sample of those are outlined in the table below. Examples of Offences from POEO Regulations failing to comply with a clean-up notice failure to pay a clean-up notice fee failing to comply with a prevention notice failure to pay a prevention notice fee polluting waters causing air pollution Proposed Penalty (individual) $750 $500 $750 $500 $750 $750 Proposed Penalty (corporation) $1500 $1000 $1500 $1000 $1500 $1500 Section of Act 91 94 97 100 120 124 – 8 MBA Environmental Training Course 117 Penalty Infringement Notices are appealable. It is imperative therefore when issuing a Penalty Infringement Notice that all care and attention is taken to the gathering of appropriate evidence to support your case for the issue of a PIN. e) Other Penalties The POEO Act has a three tier offensive system. Tier Three offences (minor offences) are dealt with through the issue of a Penalty Infringement Notice. Tier Two offences can attract penalties of up to $250 000 for corporations and $120 000 for individuals. Tier One offences are the most serious environmental offences. They can attract fines of up to $1 million for a corporation, clean up costs, frozen assets and damages while for individuals the penalty can be up to $250 000 and/or seven years imprisonment as well as clean up costs, frozen assets and damages The POEO Act is a very flexible and useful piece of legislation. Environmental Planning and Assessment Act (1979) The Environmental Planning and Assessment Act (EP&A) (1979) gives Councils responsibility for the management of their land. That management responsibility operates over a number of levels including • • Land use planning (Part 3). Through the EP&A Act Councils are required to prepare and manage land use plans. These land use plans also impose development controls Development assessment (Part 4). Through this part of the Act Councils are required to assess the suitability or otherwise of all developments in their area. Councils can exclude certain types of activities from the formal assessment process yet these are usually only very minor. Councils can also require specific Erosion and Sediment Control Plans or soil or water management plans at the development assessment phase. Councils across the state have different approaches to the process of development assessment. Some have a common approach of requiring an Erosion and Sediment Control Plan for developments up to 2500 square MBA Environmental Training Course 118 meters and a more detailed Soil and Water Management Plan on developments over that size. Other councils decide on their erosion and sediment control requirements on an ‘application by application’ basis. If the applications do not meet Council's requirements it can be rejected. • Development consent. Councils usually impose erosion and sediment control conditions on development consent. These conditions can vary from basic requirements through the use of standard conditions to more detailed job specific requirements. A number of sections of the EP&A Act give Councils authority to act against builders or developers who breach their conditions of consent. The tools that can be used in the relevant sections of the Act include o PIN – Section 127a o CAN – Section 125(1) through local court prosecution o Summons – Section 125(1) through Land and Environment Court prosecutions o Order 15 – through Section 121b o Application for Land and Environment Court orders – Through Class 4 Section 123 Through this Act Councils have the authority to minimise the potential of erosion and sediment control at the planning and application phases as well as through the construction phase. Different councils across the state used the key parts of the legislation differently. Many have found the EP&A Act to be successful in ensuring local environments are protected. Others have found the POEO Act to be more helpful. Other Legislation While the three main laws outlined above are the main ones that Councils need to be aware of, there are many other pieces of legislation that Councils need to comply with, including for example: • National Parks and Wildlife Act (1974) MBA Environmental Training Course 119 • Threatened Species and Conservation Act (1995) • Coastal Protection Act (1979) • NSW Heritage Act (1977) • Fisheries Management Act (1994).

NAME: Ray Carden RESPONSE: Environmental Management Plan NAME: Oscar Andereazza RESPONSE: Topics were well structured and delivered by the presenters in easily understood language supported by an excellent reference document. NAME: Antonia Krali RESPONSE: All components were extremely helpful, but especially the erosion and sedimentation control as it was very perceptive. The speed & length of the course was also ideal in keeping us moving along whilst giving us the information relevant to primary contractors. NAME: Paul Caristo RESPONSE: Chris – very good presenter Sharon – good to be taught by someone with that background NAME: Tom Peters RESPONSE: The Law and Waste Minimisation NAME: Dan Naidoo RESPONSE: All areas covered within this course were beneficial which can be applied at my workplace, home and within my community. NAME: Andrew Summons RESPONSE: Erosion and Sediment Control (the drain is just for rain, not pollution). Please identify any components of the course that you found least worthwhile and why. NAME: Iliga Ilcesin RESPONSE: Noise, Air Pollution, Haz. Substances – felt it was a little rushed. NAME: Trevor Smith RESPONSE: 1) Pictures in slides not readily clear (due to distance – maybe one slide per photo) 2) Less time on sediment control examples. NAME: Dale Anderson RESPONSE: From what I saw I liked the entire course. NAME: Allan Starkey RESPONSE: N/A – every component of the course was excellent NAME: Ray Carden RESPONSE: The second video NAME: Oscar Andereazza RESPONSE: I could not identify any weaknesses. However, MBA video on Waste Minimisation referred to obtaining clean fill from a townhouse development site which was a factory building – unlikely. NAME: Antonia Krali RESPONSE: All were worthwhile – I wouldn’t change/eliminate any, but I would like more time given to contractor management and auditing with particular strategies to encourage/achieve compliance. NAME: Paul Caristo RESPONSE: All important. NAME: Tom Peters RESPONSE: Sediment control, only because it seemed to monopolise time. The % ratio that was devoted to it was too high. I feel other matters could have been expanded – the pm session. NAME: Dan Naidoo RESPONSE: None. NAME: Andrew Summons RESPONSE: Managing Subcontractors (hard to control). Please identify any aspect of environmental management on building and development sites that you believe should have been covered by the course and were not dealt with. NAME: Iliga Ilcesin RESPONSE: Role of Environmental Consultants and Private Certifiers. NAME: Trevor Smith RESPONSE: Possibly link some examples to “Basix” with regard to some landscaping elements being installed earlier in project – to save double production for diversion/catchment. NAME: Dale Anderson RESPONSE: The information was clear and I believe the folder will help to fill in any gaps. NAME: Allan Starkey RESPONSE: Tree preservation. NAME: Ray Carden RESPONSE: Nil. NAME: Oscar Andereazza RESPONSE: Management of small/minor works and job sites (focus tended to be on major sites). NAME: Antonia Krali RESPONSE: The course outlined different types of controls, but be more specific about which circumstances require which types of control and how each control works; i.e. I was a little lost on the way straw bales work. NAME: Paul Caristo RESPONSE: - Individual case specific examples - Cultural/language barriers - Advances in technology NAME: Tom Peters RESPONSE: Practical approaches to tight sites – practice examples, not just goals. NAME: Dan Naidoo RESPONSE: Pollution and energy rating. NAME: Andrew Summons RESPONSE: Nil. Would you recommend the course to any of our colleagues? Why/why not? NAME: Iliga Ilcesin RESPONSE: Yes, although recommend the course start at 8am and finish around 5pm as the second half of the course was too rushed. NAME: Trevor Smith RESPONSE: Yes – filling a need for information that is loosely sought. Amalgamation of processes usually seen as separate. NAME: Dale Anderson RESPONSE: Yes – because it should become common knowledge to all people involved in the building industry. NAME: Allan Starkey RESPONSE: Yes – the course is very educational and awareness of penalties and fines NAME: Ray Carden RESPONSE: Yes – to learn more about Environment Management of Building Industry. NAME: Oscar Andereazza RESPONSE: Yes – but due to the pace of the presentation they would need to have some understanding of laws and concepts. NAME: Antonia Krali RESPONSE: Absolutely – it was a very well timed course (i.e. 5 hours) and provides all the information required for future review (which is necessary if any real change is to be affected) but is very successful in introducing the issues and concepts and thus introducing awareness. NAME: Paul Caristo RESPONSE: Yes – all builders/ head contractors should do this course. NAME: Tom Peters RESPONSE: Yes – with regard to obligations; management more so than mid level due to its predominately goal oriented focus. Site level staff would be served better with more practical details. NAME: Dan Naidoo RESPONSE: Yes – this will better educate all to understand the benefits to the environment. NAME: Andrew Summons RESPONSE: Yes – informative. Any other comments NAME: Iliga Ilcesin RESPONSE: Could you please send me some contact details for Councils that the MBA can call re. organising 1-2 week seconolments for our staff (so they can learn more about Environmental Compliance, inspections, hazards, legislation, etc.). NAME: Trevor Smith RESPONSE: List of websites with further information. NAME: Dale Anderson RESPONSE: I thank the presenters in helping me to understand the method ideas and challenges in site management. NAME: Allan Starkey RESPONSE: Very professional presentation. NAME: Ray Carden RESPONSE: Room too large. NAME: Oscar Andereazza RESPONSE: Excellent course that was well presented. NAME: Antonia Krali RESPONSE: Excellent presentation – really kept up our interest and the mix of tasks vs videos vs slides was excellent. AND – thanks for the CD, will also be very helpful. NAME: Paul Caristo RESPONSE: Should be more focused in construction industry on contents of course. Large construction companies producing waste should factor the control into time programs and budgets. NAME: Tom Peters RESPONSE: Both facilitators seemed very passionate. Chris especially had a no nonsense approach, which I liked. Thanks for the opportunity. Didn’t really need to bring plan.

Builder Developer Training Program © 2005 Gems Pty Limited 3 Section 2 – The Laws in Relation to Erosion and Sediment Control: An Overview The main laws that govern the management of erosion and sediment control on building and development sites are: 1.Environmental Planning and Assessment Act (1979) • Development applications – builders/developers are often required to submit erosion and sediment control plans or soil and water management plans with applications. • Development consent – Council usually includes erosion and sediment control conditions on development consent. A number of sections of the EP&A Act give Councils authority to act against builders or developers who breech their conditions of consent. The tools that can be used in the relevant sections of the Act include: • PIN – Section 127a: most often used for non-compliance with development consent and conditions; • Other sections include 125(1) 125b, and Section 123. Builder Developer Training Program © 2005 Gems Pty Limited 4 2. Protection of Environment Operations Act (1997) Basic thrust of this law is the concept of due diligence. The law also introduces new enforcement tools: • Clean Up Notices (Section 91); - Can be issued when a pollution incident has occurred or is likely to occur; - Can require immediate action; - Must specify a period in which the clean up must be taken; - No right of appeal - ignoring a notice is against the law; - Recipient required to pay a fee for receiving the notice - $320.00; - ARA keeps the money. NB: Direction notice, not a penalty notice. • Prevention Notices (Section 96); - Can be issued when an activity is being carried on in an environmentally unsatisfactory manner; - Should specify actions required to ensure activity is carried on in an environmentally satisfactory manner; - Cannot require action within 21 days; - Can be appealed; - Recipient required to pay a fee for receiving the notice - $320.00; Builder Developer Training Program © 2005 Gems Pty Limited 5 • Compliance Cost Notices (Section 104); - Enable Councils to recover the costs of ensuring compliance with Clean Up and Prevention Notices; - Costs con include costs for monitoring action and costs for Council doing the clean up voluntarily or under direction from DEC. • Penalty Infringement Notices (PIN) (range of Sections); - Operate like an on-the-spot fine; - Fines attached are set in the act; - A sample of those is outlined in the table below: Examples of Offences from POEO Regulations Proposed Penalty (individual) Proposed Penalty (corporation) Section of Act failing to comply with a clean-up notice failure to pay a clean-up notice fee failing to comply with a prevention notice failure to pay a prevention notice fee polluting waters causing air pollution $750 $1500 91 $500 $750 $1000 $1500 94 97 $500 $750 $750 $1000 $1500 $1500 100 120 124 – 8 Builder Developer Training Program © 2005 Gems Pty Limited 6 3. Local Government Act (1993) (as amended 1997) • Outlines overarching responsibilities for Council in terms of ensuring the local environment is effectively managed. • Section 8 requires Councils to “Properly manage, develop, protect, restore, enhance and conserve the environment of the area for which it is responsible”. • Section 124a allows Councils to issue Enforcement Notices under the Act; a useful catch Law. Section 3 – Erosion and Sedimentation: What Causes It? • Erosion is the wearing away of the land by the action of rainfall, running water, wind, moving ice or gravitational creep. • Soil detachment (erosion) occurs when the erosive forces from rain drop impact and/or flowing water exceeds the soils resistance. • Sediment is the bi-product of erosion; the small soil particles that have been detached. • Sedimentation occurs when the transportation of detached soil particles ceases and soil particles settle or fall out of suspension. Builder Developer Training Program © 2005 Gems Pty Limited 8 Section 4 – Principles of Erosion and Sediment Control on Building and Development Sites Planning Prepare an Erosion and Sediment Control Plan for your site before works start and submit it with your building application. The plan should show how you will prevent stormwater pollution throughout the construction phase and until the site landscaping has been completed, i.e., the erosion hazard has been reduced to an acceptable level. Different controls might be necessary at different stages over the construction phase as the nature of the site changes, e.g., changing drainage patterns, moving stockpiles to different places, etc. If such changes are likely, these must be shown on the Plan. Installation of Controls Before works start, set up the erosion and sediment controls and install a sign warning everyone of the penalties of pollution (this may be provided by Council). Make sure that all site workers understand their individual responsibilities in preventing pollution. A recommended sequence for setting up controls is: i) establish a single stabilised entry/exit point to the site; ii) install sediment fences along the low side of the site; iii) divert upslope water around the site and, if Builder Developer Training Program © 2005 Gems Pty Limited 9 necessary, stabilise the channels and outlet; iv) clear only those lands which need to be disturbed during the building works. Put up a barrier fence around areas where the vegetation is to not be disturbed; v) ensure that any stockpiles are on your land – not the footpath of the next-door neighbour’s land. Where necessary, seek approval from the Council or your neighbour(s) for any offsite stockpiles. Ensure stockpiles have appropriate erosion and sediment controls; vi) install onsite waste receptacles, such as skips or bins, and wind-proof litter receptacles; vii) start building works; viii) install and connect roof downpipes to the stormwater then the roof is completed; and ix) stabilise and exposed earth banks when the building works are completed. Maintenance of Controls All erosion and sediment control works should be checked at least once a week and after each rainfall event to ensure they are working properly. Maintenance might include: i) Removing sediment trapped in sediment fences, catch drains or other areas; ii) Topping up the gravel on the stabilised access; repairing any erosion of drainage channels; and iii) Repairing damage to sediment fences. Remember that the erosion and sediment control works might need to change as the slope and drainage paths Builder Developer Training Program © 2005 Gems Pty Limited 10 change during the development phase. Best practice includes anticipation of the likely risks and being prepared for unusual circumstances, e.g., having spare sediment fence material on the site. Finalisation of Works Ensure that 75% of the site is stabilised before removing the erosion and sediment controls. If landscaping is not completed before handing over the site to the owners, ensure they are aware of their responsibilities under the PoEO Act to prevent pollution. Four Basic Principles i) Make sure everyone working on the site understands how important it is not to pollute stormwater. ii) Do not disturb more of the site than you have to. iii) Install erosion and sediment controls before starting work. iv) Maintain your erosion and sediment control works throughout the construction phase. Builder Developer Training Program © 2005 Gems Pty Limited 11 Section 5 – Erosion and Sediment Control: the Tools and Systems Minimising Erosion 1. Minimising Impact of Flowing Water • Diversion of upslope water where practical. Upslope water should be diverted around the site. • Small turf or geotextile lined catch drains or diversion banks can be used. • Diverted stormwater should be discharged onto stable areas, and should not be diverted into neighbouring properties; • Connect downpipes to stormwater as soon as gutter is fixed; • Diversion of water around onsite stockpiles; • Designated rubbish areas 2. Minimising Raindrop Impact • Maintain as much vegetation on site as is practical; • Encourage mulching of cleared areas; A range of tools available for mulching, including: • Plant material • Fabrics. Builder Developer Training Program © 2005 Gems Pty Limited 12 3. Minimising movement on site • Established stockpile areas; • Established waste minimisation areas; • Established stabilised entry/exit point – usually required by Council’s Standard Conditions of Approval. Should be designed and signposted to ensure it is a common entry and exit point for all movements on or off site. The standard drawing for stabilised drawing for entry/exit points from the “Blue Book” is outlined on the next page. Builder Developer Training Program © 2005 Gems Pty Limited 13 Builder Developer Training Program © 2005 Gems Pty Limited 14 Sediment Control Sediment control is about putting in place systems that slow the flow of sediment laid water in order for sediment to settle out and be captured. A range of tools are available for sediment control, including: • Sediment fencing (the construction notes for sediment fencing from the “Blue Book” are outlined below); EMS Training © 2005 Gems Pty Limited Waverley Municipal Council Other sediment control devices include: • Sediment socks; • Hay Bales; • Sandbags; • Sand or gravel sausages; • Sediment traps; • Turf strips. See Appendix 2: “Basic Erosion and Sediment Control Tools – Advantages and Disadvantages” for more information. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 16 Section 6 – Erosion and Sediment Control Plans/Soil and Water Management Plans Nearly every Council across the state is now requiring builders/developers to prepare an Erosion and Sediment Control Plan (ESCP) or a Soil and Water Management Plan (SWMP) showing how they will minimise soil erosion and trap sediment that may be eroded from the site during the construction phase. Some Councils require this plan to be submitted with the development application, while others require it to be submitted before they issue a construction certificate. The complexity of the plan depends upon the nature and scale of any particular development, but especially the amount of land likely to be disturbed. Small scale development such as house extension and the construction of small driveways will not require a plan, but should still be undertaken in a manner which reduces pollution risk. The plan should be a stand alone document consisting of both drawings and a commentary that can be understood easily by all site workers. Outlined on the following pages is a model Erosion and Sediment Control Plan developed by Landcom for a single lot residential building. It contains all lead key components, i.e., the drawing, the commentary and the standard drawings. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 17 A Model Erosion and Sediment Control Plan The Drawing EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 18 Inclusions for Drawing It is essential that the following information at the very least represented on the drawing: • • • • • Location of site boundaries and adjoining roads; Appropriate grades and indications of directions of fall; Approximate location of trees and other vegetation showing items for removal or retention (consistent with other plans attached to the application); Location of site access, proposed roads and other impervious areas, (e.g., parking areas and site facilities), existing and proposed drainage patterns for stormwater discharge points; North point and scale. The Commentary The Commentary is usually provided with a drawing. The Commentary usually outlines the sequence of events that will take place onsite. Below is a sample commentary provided as a guideline. 1. Site works will not start until the erosion and sediment controls outlined in clauses 2 to 4, below, are installed and functional. 2. The entry/exit of vehicles from the site will be confined to one stabilised point. Sediment or barrier fencing will be used to restrict all vehicular movements to that point. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 19 Stabilisation will be achieved by either: - constructing a sealed (e.g. concrete or asphalt) driveway to the street constructing a stabilised site access following Standard Drawing SD 6-14 or other suitable technique approved by the Council. 3. Sediment fences (SD 6-8) and barrier fences will be installed as shown on the attached drawing. 4. Topsoil from the work’s area will be stripped and stockpiled (SD 4-1) for later use in landscaping the site. 5. All stockpiles will be placed in the location shown on the ESCP and at least 2 metres clear of all areas of possible areas of concentrated water flow, including driveways. 6. Lands to the rear of the allotment and on the footpath will not be disturbed during works except where essential, e.g. drainage works across the footpath. Where works are necessary, they will be undertaken in such a way to minimise the occurrence of soil erosion, even for short periods. They will be rehabilitated (grassed) as soon as possible. Stockpiles will not be placed on these lands and they will not be used as vehicle parking areas. 7. Approved bins for building waste, concrete and mortar slurries, paints, acid washings and litter will be provided and arrangements made for regular collection and disposal. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 20 8. Guttering will be connected to the stormwater system or the rainwater tank as soon as practicable. 9. Topsoil will be re-spread and all disturbed areas will be stabilized within 20 working days of the completion of works. 10. All erosion and sediment controls will be checked at least weekly and after rain to ensure they are maintained in a fully functional condition. Standard Drawings The Soils and Construction (Vol 1) (4th Ed. March 2004) – Managing Urban Stormwater (the Blue Book) is the definitive guide to erosion and sediment control for all types of works. The Blue Book contains standard drawings for the more common features of erosion and sediment control activities. It is not unusual to attach standard drawings to an Erosion and Sediment Control Plan. Outlined on the following pages are the standard drawings included in the sample Landcom document. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 21 EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 22 EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 23 Soil and Water Management Plans Soil and Water Management Plans are often required when a development is large (a common rule of thumb used by planners is for developments over 2500m2) or for sites that have the potential to impact on environmentally significant features of local communities. Soil and Water Management Plans are much more detailed than Erosion and Sediment Control Plans. They are usually prepared by people with expertise in erosion and sediment control. These would include those personnel approved by the Consent Authority or those certified by: • • • the Institution of Engineers, Australia, for engineering and hydrology matters; the International Erosion Control Association CPESC Program for soil conservation matters; The Australian Society of Soil Science, for collection or analysis of soil data. Along with all the information provided in an Erosion and Sediment Control Plan, the “Managing Urban Stormwater – Soils and Construction, Vol. 1 (March 2004) (the Blue Book) suggests Soil and Water Management Plans should also include: • the location of lots, public open space, stormwater drainage systems, schools, shopping community centres; EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 24 • the location of land designated or zoned for special used; • the location and general diagrammatic representations of all necessary erosion and sediment control BMP; • the location and engineering details of supporting design calculations for all necessary sediment bases; • location of basic details of any other facilities proposed to be included as part of the development, works such as constructed work lands, gross pollutant traps, or trash racks or trash collection separator units. The plan should also specify the scale, type, operation and maintenance of all soil and water management devices in the soil and water management program. On larger sites (where more than 2500m2 of land is disturbed), identify all items listed above, as well as: (i) (ii) the following information: • the location of lots, public open space, stormwater drainage systems, schools, shopping/community centres • the location of land designated or zoned for special uses • existing site contours; the location and general diagrammatic representations of all necessary: • erosion and sediment control BMPs; EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 25 (iii) (iv) location and engineering details with supporting design calculations for all necessary: • sediment basins; and location and basic details of any other facilities proposed to be included as part fo the development or works, such as: • constructed wetlands • grass pollutant traps • trash racks or trash collection/separator units. Detailed design criteria for these latter facilities should be sourced from other manuals/reports and are not an integral part of a construction phase SWMP. Usually they are considered as a separate function of the development approval process. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 26 Section 7 – Common Problems on Building and Development Sites Typical Problems Include… • No systems or tools at all; • Right systems of tools but in the wrong place or poorly fitted; • Wrong systems; • Poorly maintained systems. • Sediment fence not dug in 150mm; • Stakes in sediment fence too wide apart; • Sediment fence constructed across the contour, no turn backs; • Sediment fence fitted in areas of concentrated flow; • No stabilised entry; • No upslope drain controls; • No diversion around stockpiles; • Stockpiles above 2m high; EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 27 • Downpipes not connected as soon as roof is completed; • Hay bales used in the wrong place; • Removal of all vegetation from site when it’s not necessary; • Removal if potential filter strips, i.e. bushland or turf, before any construction occurs; • Poor management of subcontractors on site. See Appendix 3 – Onsite Erosion and Sediment Control Audit Tool EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 28 Section 8 – Summary EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 29 Appendix 1: Summary of the Laws EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 30 An Overview of the Laws relating to the management of erosion and sediment control on Council and other building and development sites There are general laws that outline Councils broad environmental responsibilities and specific laws that outline Council operational and management enforcement responsibilities. Outlined below is the summary of the requirements of those laws. The Local Government Act 1993 (as amended 1997) The Local Government Act outlines overarching responsibilities for Council in terms of ensuring the local environment is effectively managed. The first stated purpose of the NSW Local Government Act (section 7a) is ‘to provide the legal framework for an effective, efficient environmentally responsible open system of local government in NSW.’ Another stated purpose of the Act (section 7e) is to ‘require Council’s, Councillors and Council employees to have regard to the principal of ecologically sustainable development in carrying out their responsibilities.’ The Local Government Act 1993 (as amended 1997) (section 8) sets out the charter of a local Councils in NSW and includes the requirements for a Council to ‘properly manage, develop, protect, restore, enhance and conserve the environment of the area for which it is responsible.’ Section 402 of The Local Government Act (1997) sets out the contents of a Council’s draft management plan and also requires that the statement of principal activities must include particulars with respect to ‘activities to properly manage, develop, protect, restore and conserve the environment.’ So the Local Government Act sets a broad agenda for Council. Specific links could then be made from this act to Councils erosion and sediment control responsibilities in all areas of activity. It should be noted that Council does have power to issue enforcement notices under Section 124 of the Local Government Act but the general view of Councils identified through the research was that the Protection of the Environment Operations Act (1997) was a much more useful and flexible enforcement tool. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 31 Protection of the Environment Operations Act (1997) This is the main environmental protection law in NSW. This law can be used by the Department of Environment and Conservation (DEC (NSW)) to deal with inappropriate practice on Council sites. It can also be used by Council to deal with inappropriate practice on building and development sites in their area. This Act requires any individual or organisation carrying out any activity to ensure that activity is completed with ‘due diligence’ or ‘all reasonable care’ in order to ensure the environment is protected. The DEC (NSW) has indicated in a number of publications that ‘due diligence’ means: taking all reasonable steps to prevent pollution and protect the environment promoting action to prevent or minimise potential environmental damage showing that all that could have reasonably been done to prevent an incident from occurring has been done ensuring that all precautionary and control measures are in place and are regularly checked and maintained to minimise the risk of an environmental incident. As well as the broad due diligence requirements, the Act also provides the DEC (NSW) and Council with some specific enforcement tools. These tools include Clean Up Notices (Section 91). Under Section 91 of the Act, authorised officers do not have to wait for the environment to be harmed before they can take action. Authorised officers from both the DEC (NSW) and Council can issue Clean Up Notices at sites where they are of the view that an incident has occurred or is likely to occur. The Clean Up Notice is a direction notice and not a penalty notice in that its purpose is to direct the person or organisation receiving it to take action in order to minimise environmental harm. The Notice must outline the actions required in broad terms and must specify a deadline for those actions to be taken. A Clean Up Notice can require immediate action. A Clean Up Notice can also be served verbally but must be followed up in writing within 72 hours. Clean Up Notices are also not appealable and so any person receiving a Clean Up Notice must do what it says. If a person receiving a Clean Up Notice decides not to take the nominated actions, they can receive a Penalty Infringement Notice (PIN) for a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 32 000 for individuals and $250 000 for corporations. Councils and the DEC (NSW) can also charge an administrative fee of $320 for the issue of a Clean Up Notice. Failure to pay this fee can also attract a fine for up to $1000. Councils and the DEC (NSW) can decide not to impose the fee. Clean Up Notices appear to be the most widely used enforcement tool for minimising erosion and sediment loss on building and development sites. Clean Up Notices can be used for example on building sites with no or poorly maintained erosion and sediment control in place even if its not raining. Councils have also used Clean Up Notices to require developers to sweep the streets around their development sites at the end of every day. There is also authority within this Act for Councils to take the clean up action themselves if the person receiving the notice chooses not to within the designated time. Councils can recover the costs associated with completing this work from the person or organisation who received the original notice (see Part C – Compliance Cost Notices). Prevention Notices (Section 96). Prevention Notices are for more systematic environmental challenges. They are used in response to ‘environmentally unsatisfactory behaviour.’ Prevention Notices are appealable and so cannot require action within 21 days. A Prevention Notice also outlines the actions a person is required to take and provides a deadline for those actions to be completed. If a Prevention Notice is not appealed or upheld on appeal and a person chooses not to carry out the actions outlined in the prevention notice it is a breach of the POEO Act and will attract a fine of $750 for an individual and $1500 for a corporation per day. The maximum penalty that may be imposed upon conviction for non compliance with a notice (Section 97) is $120 000 for individuals and $250 000 for incorporations. The DEC (NSW) and Council can also charge an administrative fee of $320 for serving the notice. Given the need to allow 21 days for any action to be implemented, it is unlikely that many Prevention Notices will be used to encourage more effective erosion and sediment control on Council or privately operated building and development sites. Compliance Cost Notice (Section 104) Compliance Cost Notices enable Councils to recover the costs of ensuring compliance EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 33 with Clean Up and Prevention Notices. These costs can include the cost of monitoring action taken under a Clean Up or Prevention Notice and the cost of a Council doing a clean up voluntarily or under direction from the DEC (NSW). For example if Council issues a Clean Up Notice to a developer requiring them to sweep the streets at the end of every day and upon investigation finds this action has not been taken, and Council is within their rights to bring the Councils street sweeper to the site in order to carry out the Clean up Action. The cost of the street sweeper as well as the cost associated with the Council officer visiting the site can all be included in a Compliance Cost Notice. Council is also within their rights to fine the developer for non compliance with a Clean Up Notice. Penalty Infringement Notices (PIN). (A range of Sections) Most erosion and sediment control breaches will be dealt with through the issue of a Penalty Infringement Notice. The Penalty Infringement Notice operates like an ‘on the spot fine.’ The fines attached to Penalty Infringement Notices are set in the Act. A sample of those are outlined in the table below. Examples of Offences from POEO Regulations failing to comply with a clean-up notice failure to pay a clean-up notice fee failing to comply with a prevention notice failure to pay a prevention notice fee polluting waters causing air pollution Proposed Penalty (individual) $750 $500 $750 $500 $750 $750 Proposed Penalty (corporation) $1500 $1000 $1500 $1000 $1500 $1500 Section Act of 91 94 97 100 120 124 – 8 Penalty Infringement Notices are appealable. It is imperative therefore when issuing a Penalty Infringement Notice that all care and attention is taken to the gathering of appropriate evidence to support your case for the issue of a PIN. Other Penalties The POEO Act has a three tier offensive system. Tier Three offences (minor offences) are dealt with through the issue of a Penalty Infringement Notice. Tier Two offences can attract penalties of up to $250 000 for corporations and $120 000 for individuals. Tier One offences are the most serious environmental offences. They can attract fines of up to $1 million for a corporation, clean up costs, frozen assets and damages while for EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 34 individuals the penalty can be up to $250 000 and/or seven years imprisonment as well as clean up costs, frozen assets and damages The POEO Act is a very flexible and useful piece of legislation. Environmental Planning and Assessment Act (1979) The Environmental Planning and Assessment Act (EP&A) (1979) gives Councils responsibility for the management of their land. That management responsibility operates over a number of levels including Land use planning (Part 3). Through the EP&A Act Councils are required to prepare and manage land use plans. These land use plans also impose development controls Development assessment (Part 4). Through this part of the Act Councils are required to assess the suitability or otherwise of all developments in their area. Councils can exclude certain types of activities from the formal assessment process yet these are usually only very minor. Councils can also require specific erosion and sediment control plans or soil or water management plans at the development assessment phase. Councils across the state have different approaches to the process of development assessment. Some have a common approach of requiring an Erosion and Sediment Control Plan for developments up to 2500 square meters and a more detailed Soil and Water Management Plan on developments over that size. Other councils decide on their erosion and sediment control requirements on an ‘application by application’ basis. If the applications do not meet councils requirements it can be rejected. Development consent. Councils usually impose erosion and sediment control conditions on development consent. These conditions can vary from basic requirements through the use of standard conditions to more detailed job specific requirements. A number of sections of the EP&A Act give Councils authority to act against builders or developers who breach their conditions of consent. The tools that can be used in the relevant sections of the Act include PIN – Section 127a CAN – Section 125(1) through local court prosecution Summons – Section 125(1) through Land and Environment Court prosecutions Order 15 – through Section 121b EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 35 Application for Land and Environment Court orders – Through Class 4 Section 123 Through this Act Councils have the authority to minimise the potential of erosion and sediment control af the planning and application phases as well as through the construction phase. Different councils across the state used the key parts of the legislation differently. Many have found the EP&A Act to be successful in ensuring local environments are protected. Others have found the POEO Act to be more helpful. Other Legislation While the three main laws outlined above are the main ones that Councils need to be aware of, there are many other pieces of legislation that Councils need to comply with, including for example: National Parks and Wildlife Act (1974) Threatened Species and Conservation Act (1995) Coastal Protection Act (1979) NSW Heritage Act (1977) Fisheries Management Act (1994).

Sediment control measures aim to capture eroded soil particles by either slowing the velocity of water flow so that soil particles can settle out by gravity or by chemical treatment to flocculate suspended soil particles. As sediment is only generated when soil erosion occurs, installation or construction of erosion control measures should be the first priority. Erosion control is also easier and cheaper than sediment control. Although the list of measures is comprehensive it is not exhaustive. New erosion and sediment control technologies are being developed all the time. The measures described are proven and are known to work if designed and implemented correctly. Permanent erosion and sediment control measures require formal design. Failure to undertake formal design in most instances is an unacceptable risk. Erosion and sediment control is not rocket science, however, inappropriate or poorly designed or installed control measures can often cause more problems than they solve. When in doubt seek independent expert advice. Many self proclaimed erosion and sediment control experts are product suppliers and therefore have a vested interest in promoting their product over what is right for the sight. Be aware of this when seeking erosion and sediment control advice from salesmen. Expert advice can be obtained from Certified Professionals in Erosion and Sediment Control (CPESC) through the International Erosion Control Association (Australasia) (IECA). The Government guideline “Managing Urban Stormwater – Soils & Construction” or also known as the “Blue Book” is a great reference book that can assist with selection of products. EROSION & SEDIMENT CONTROL MEASURES EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 38 Surface Roughening – Track Walking Description: A technique that leaves the soil surface in a roughened state to increase water infiltration, decrease and slow down run-off and to encourage sediment retention and vegetation establishment. It also discourages vehicular traffic across the soil surface. Application: For any slope that is safe for the use of machinery. For trackwalking maximum 1(v):2(h). Installation Aspects: Upslope run-off should be diverted away from the slope to be treated. Problems: Upslope stormwater is not diverted around area and rill erosion will occur. Turf Description: Refers to a layer of topsoil and grass harvested from the field by specialist machinery. Rolls can be supplied up to 5 m wide by 9m long. Reinforced turf in similar to conventional turf except that grass is grown through an artificial 2 dimensional poly-propylene grid to provide additional strength. Application: Turf and Reinforced Turf can be used in both sheet flow and concentrated flow situation to provide erosion protection. It is often used as a “softer” alternative to “hard” channel linings such as rock and concrete in urban situations. Design/Construction Aspects: Turf is only capable of withstanding relatively low flow velocities. Reinforced Turf can withstand flow velocities a lot higher than turf. Deposited sediment can kill turf. For this reason upstream erosion protection and sediment detention measures must be installed before the turf can be placed. As turf and reinforced turf rely on the grass root system for strength, the substrate on to which the turf is being placed must be suitable for vegetation establishment. The edges of the turf/reinforced turf must be installed flush with the existing soil surface so that erosion along the turf/soil interface does not occur. Problems: Deposited sediment can kill turf. Due to the way reinforced turf is EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 39 grown, the roots can become “root bound” and therefore the time for the roots to bind into the soil surface is increased thus increasing the erosion/failure potential. Turf must be watered until adequately established. Erosion Matts and Blankets Description: A rolled matt or blanket made from jute, coconut fibre, wool, nylon and poly-propylene that is placed on the soil surface to protect it from raindrop impacts and low velocity sheet and concentrated flows. Application: Erosion control blankets are used on batters and embankments and other sheet flow environments to protect the soil from erosion and promote vegetation. Blankets are generally temporary measures and are designed to biodegrade. Typically these products are made from wood fibre, wool and jute. Erosion control matts are designed to be used in concentrated flow environments and are therefore made from more durable materials such as jute, coconut fibre, nylon and poly-propylene. Design/Construction Aspects: Due to the vast range of proprietary products available, independent advice should be sought on the appropriate matt/blanket for a particular situation. Manufactures supply product specifications and installation guidelines. Problems: When blankets are placed in concentrated flow areas. A blanket is designed to cover the ground from raindrop impact and a matt is a heavier product designed for concentrated flow. Remember B is for blanket as in Batter. Rock Check Dams Description: A small temporary rock weir structure. Can also be constructed from sandbags and logs. Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. The middle of the Check Dam must have a spillway to stop water running EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 40 around the ends. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. Surface Mulching Description: Mulching is the placement of a protective cover over the soil surface to protect it from the erosive effects of raindrop impact and shallow sheet flows. Common mulch materials include wood chip, straw, wood fibre, paper pulp, bagasse, brush matt and bitumen emulsion. Application: The type of mulch to be used in dependant on the type of environment to be protected, climatic conditions, location and available mulch material. Design/Construction Aspects: Common to most situations where mulches are to be used, divert flows away from the area to be protected. The application of mulch material should be even and uniform. Problems: Mulch washed away due to failure to divert flows away from mulched area. Erosion due to insufficient quantity of mulch or tackifier. Weed infestation due to weed contaminated mulch (eg hay instead of clean straw). Vegetation Description: For erosion purposes vegetation includes native and introduced grasses, ground covers, shrubs and trees. Application: Any erosion control program will benefit from temporary and permanent vegetation covers. The above ground vegetative material provides protection from raindrop impact, slows flow velocities and traps eroded soil particles. Roots help bind the soil surface thus minimising erosion. Problems: Weed infestation due to the use of contaminated seed. Difficulty in maintaining an adequate vegetative cover due to climatic/soil constraints. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 41 Sediment Fence Description: A sediment fence is a temporary barrier of permeable geotextile, partially installed in a trench and supported by posts. Design/Construction Aspects: Not to be used in concentrated flow. Silt fence should be installed on the contour with the ends turned up so that the turnup ground level is equal to the top fabric level at its lowest point. Sediment fence must be anchored in a 150mm deep compacted backfilled trench. The sediment fence posts must be on the downslope side of the fabric otherwise the fabric will come away from the peg when put under pressure. Problems: Not installed with a turnback at either end causing water to run around the ends. Not trenched in deep enough causing fabric to pull out of the ground. Not compacting the trench after installation causing water to tunnel under the sediment control fence. (you only need to compact the ground with you boots no need for a compactor to be brought in) Check Dams Description: A small temporary rock weir structure. Can also be constructed from sandbags and logs. Application: Used as temporary erosion protection and limited coarse sediment retention in concentrated flow environments such as perimeter and table drains by limiting flow velocity. Not to be used major flow lines or streams. Design/Construction Aspects: Rock check dams are temporary measures and therefore do not require formal design. Check dams should be installed so that the toe of the upslope check dam is the same level as the crest of the immediate downslope dam. Problems: Erosion around the edge of the dams due to insufficient spillway depth. Erosion immediately downslope of the check dam to insufficient rock protection. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 42 Straw Bales Description: A small temporary dam. Straw bales are suitable for low flows of water. It is only recommended that these be used in limited applications. They maybe used to reduce the flow velocity of water. Design/Construction Aspects: Not to be used in concentrated flow. Straw bales should be installed on the contour with the ends turned up so that the turnup ground level is equal to the top of the middle bale. Straw bales should be anchored into the ground 100mm with a star picket post to secure. The minimum number of strawbales to be used is four. You can not make a dam with one or two strawbales. Problems: Erosion around the edge of the straw bale dam due to insufficient spillway depth and insufficient number of bales used. Remember minimum number of bales to be used is four. Erosion immediately downslope of the strawbale dam to insufficient rock protection. Sand Bags Description: Sand bags are used to make a temporary sediment trap and are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally do not have an outlet they form a pond. Application: Their function is to trap coarse sediments in both concentrated and sheet flow situations. They should be located immediately downstream of disturbed areas. Design/Construction Aspects: Sediment traps can be formed by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include not building the structure large enough to contain the amount of water that will be washed from the site. Difficulty in cleaning out sediment, due to poor location and design. EMS Training ESC Builder/Developer Training City of Sydney © 2005 Gems Pty Limited Page 43 Sediment Traps Description: Sediment traps are measures that capture eroded sediments by slowing the velocity of water so that the soil particles settle out. They generally consist of a stable inlet and outlet, and some form of pond. Application: Their function is to trap coarse sediments in concentrated flow situations. They should be located immediately downstream of disturbed areas. Design/Construction Aspects: Formal design of sediment traps is required. Sediment traps can be formed by excavating an earthern pond, or by constructing some form of structure to form a pond using materials such as rocks, logs, sandbags and rock-filled wire baskets. Problems: Common problems include inlet and outlet erosion due to inadequate erosion protection. Difficulty in cleaning out sediment due to poor location and design.
