LIST OF BACKGROUND PAPERS: 1. Main Relevant Policies Structure Plan – Policies M1, M2, M5, W1, W2 and W3; Minerals Local Plan - Policies 3,4,6,7,8,18 and 20; Waste Local Plan - Policies WLP1 , 2,3,4,11, 25,26, 27 and 30; and Local Plan 2. GB1 and GB2 Previous Relevant Decisions There are no previous relevant decisions on the application site, although applications for minerals extraction on land to the east of the site have been approved as follows: 470508 - the extraction of sand and gravel with restoration to a lake was approved in 1998; and 02/882570 - the extraction of sand and gravel with restoration to a lake on land to south of approved 470508 was also approved in 2003. An application for the retention of the existing processing plant and the formation of a new access at Poyle Quarry (all within Slough Borough) is currently before Slough Borough Council. 3. The Highway Authority The Highway Officer’s response is awaited. reported as Late Observations. 4. Any response will be Neighbour Notification Responses Only one response has been received expressing concerns over added disturbance and noise in the area; the increase of lorry traffic on the local roads; possible health impacts from dust; that part of the site should be left in its agriculture state; and that they would actively discourage any development for a quarry. 5. Horton Parish Council 6. Horton Parish Council raise no objection subject to the approval by Slough Borough Council of the application for the retention of the existing processing plant and the formation of a new access (all within Slough Borough and currently before Slough Borough Council), and the transportation of any material between this site and the Kingsmead Quarry, through Horton village, being prevented (the two sites would be worked by the same operator). . Berkshire Archaeology Berkshire Archaeology have considered the results of an archaeological evaluation report, including trial trenching) that was commissioned by the applicant from Wessex Archaeology. Berkshire Archaeology advise that the report confirms that a number of archaeological remains dating to the later Prehistoric period (the Bronze Age, Iron Age and the Romano-British periods) survive on the site, representing the managed landscape that may include settlement, agriculture and ritual use. Berkshire Archaeology further advise that these important remains will require a detailed mitigation strategy to ensure that they are either preserved in situ where possible or by recording. This matter can be covered by condition. 7. BAA (Heathrow Airport (safeguarding) ) BAA raise no objections subject to a condition. 8. English Nature English Nature object as no assessment has been made of the potential impact of the proposal on the SW London Waterbodies Special Protection Area, nor on the Wraysbury and Hythe End Gravel Pits and Wraysbury No1 Gravel Pit SSSI’s. 9. Environment Agency The Environment Agency object as insufficient information has been provided with the application. 10 Joint Strategic Planning Unit The JSPU raise no objection subject to conditions. 11 Ramblers Association The Ramblers Association emphasise the need for the highest standards of restoration and after use recreation provision. Some detailed suggestions are made. 12. Slough Borough Council Slough Borough Council raise concerns relating to a range of drainage, hydrological and hydrogeological issues; the omission of part of Preferred Area 12 from the application (a part which is in Slough Borough); impacts on footpath users; and impacts on residential properties in parts of nearby Colnbrook. 13 Three Valleys Water Three Valleys Water object over the potential impact of the proposal on an underground water supply tunnel. 14. RBWM Drainage The Drainage Officer raises concern over possible increase to risks of flooding in the area, or downstream And advises that no dewatering should take place during flooding events in the lower Colne catchment area. 15. Environmental Protection Unit The Environmental Protection Unit raise no objection subject to conditions. 16 Landscape The Landscape Officer comments on the apparent absence of a tree survey and of identified landscape benefits arising from the proposal. 17 Rights of Way The Rights of Way Officer objects as the proposal would be detrimental to the character and enjoyment of the new footpath alongside the Colne Brook and of Horton Bridleway No. 4. No attempt has been made to address the impact of the haul route on the new footpath and the Minerals Local Plan requirements for restoration have not been met. 18 Ecology Advisers (Jacobs Babtie) Detailed ecological comments are made over matters omitted from the applicants’ ecological assessment; the lack of measures for ensuring protection of the site’s ecological value; and the need for an Environmental Management Plan. It has however been established that there is no need for the applicant to undertake a survey of the site to establish the presence or otherwise of Greta Crested Newts. REMARKS Note: Members are advised that a weighty submission of documents were received just prior to this report being written and that there is likely to be some considerable Late Observations to make at the Panel meeting as there was insufficient time to digest the contents of the submission prior to the closing deadline for the agenda. This is unfortunate timing, particularly given the length of time that the applicant’s have had to respond to the Council’s requests for further information. However, it is considered beneficial that both this application and those on the adjoining site and at Kingsmead are considered on the same agenda. 1. The Site and Surroundings The application site is a flat generally open area of 21. 5 Ha of agricultural land lying to the north east of Horton. It is bounded by the south by the farm complex of buildings at Berkyn Manor Farm, to the east by areas of recent mineral extraction (now restored to lakes), to the north by the Borough boundary with Slough, and to the west by the Colne Valley Way. A small strip of land across the worked mineral area is also included as part of the application site to provide a haul route as far as the RBWM’s administrative boundary. Mineral extracted from the site would be taken via this haul route to an existing processing plant in Slough Borough Council’s administrative boundary and out through a new site access on to Poyle Road (also in Slough). A separate application, that is as yet undetermined, has been submitted to Slough Borough Council for the retention of the processing plant and the formation of the new site access onto Poyle Road. 2. The southern boundary of the site is some 400m at its closed point from the Stanwell Road. Apart from the dwellings at Berkyn Manor Farm, the nearest houses to the site within the RBWM are in Foundary Lane, some 300m to the south. The north-west corner of the site adjoins the southern end of Drift Road in Colnbrook with Slough at a distance of some 20-30m from the nearest dwelling. 3. Land immediately to the west of the site is subject to a current application 06/00588 for mineral extraction, the subject of a separate report on this agenda. These two sites are in two different ownerships and would be worked by two different mineral operators. 4. The application site forms part of Preferred Area 12 in the Minerals Local Plan (MLP) and of Preferred Area 25 in the Waste Local Plan (WLP). The MLP designation has established the extent of the site and the principle of the gravel extraction from the site subject to various detailed requirements being satisfied. The WLP identifies the site for engineered landfill (this is a landfill site whose sides are made impermeable so that it can be used for the tipping of non-inert waste). 5. The site is not the subject of any landscape or nature conservation designations. Approximately 60% of the agriculture land within the application site is classified as best and most versatile land, Grade 3a, with the remainder being Grade 3b. The Proposal 6. The proposal seeks permission for the extraction of approximately 800,000 tonnes of sand and gravel, to be worked at an average rate of some 150,000 tonnes per year. All extracted material would be taken to the existing processing plant at Poyle Quarry and would then leave the quarry via the proposed new access on to Poyle Road. Following extraction the site would be filled with inert waste and would be progressively restored to agriculture of the same clarification as exists as present. 7. To facilitate drainage the restored land would take the form of a small dome with its summit towards the northern end of the site. The summit height would be around 21.25m AOD, sloping to just under 20m on the northern edge of the boundary and toaround 19m on the southern edge. Current levels on the site range between 18 and 20m AOD. 8. It is proposed to work the site in a series of phases, starting in the north-eastern part of the site and moving generally anti-clockwise to finish in the south. Phase 2 would involve extraction in the area closest to the houses in Colnbrook where the extraction works would be pulled back from the boundary so that it would take place no closer than 80m from the nearest dwelling in Drift Way. A 3m high soil bund would be erected around the north-west corner of the working area to provide visual and noise screening to nearby residents. This bund would be extended approximately halfway along the western boundary of the site (alongside the Colne Valley Way) whilst a similar bund would also be erected along the northern boundary of the site (roughly along the RBWM /Slough boundary). Although the proposed bund does not extend the full length of the site’s western boundary (alongside the Colne Valley Way as there is insufficient soils within the site to allow this), the submitted plans indicate that no working would take place within approximately 20m of the Colne Valley Way at any point. 9. The applicant advises that the proposed restoration scheme has been designed to ensure that the site can be returned to agricultural use in a similar fashion to that which is currently employed using imported inert infill materials and the re-spreading of the stored soils. No areas of new planting are shown in the restoration scheme. The applicant further advises that the creation of any new nature conservation features has been rejected following consultation with the British Airports Authority. 10. The application is supported by an Environmental Statement. Main Planning Issues 11. The main planning issues in determining the application are considered to be (in no particular order of priority): (i) the policy issues deriving from the Minerals and Waste Local (ii) the availability of the inert filling material proposed in the quantities and at the time required for the phased restoration of the site; Plans; 12. (iii) the cumulative impact of potentially three minerals workings (land to the east of Horton Road, Kingsmead Quarry and this application site) operating simultaneously; (iv) the drainage of the site, including the impact of any changes to the groundwater, and the impact on flooding in the area; (v) the impact of noise, dust and other potential sources of pollution on local residential amenity; and (vi) planting and restoration issues. Members are advised that traffic generation issues are not identified as a main issue because the site access is in Slough BC. This is because minerals extracted from the site would be taken via a haul route across the administrative boundary between the RBWM and Slough Bourough Council, on to an existing processing plant in Slough Borough Council’s administrative boundary and out through a new site access on to Poyle Road (also in Slough). A separate application, that is as yet undetermined, has been submitted to Slough Borough Council for the retention of the processing plant and the formation of the new site access onto Poyle Road. The issue of the suitability of the access to serve the traffic generated, the environmental impacts of that traffic generation, and the routing of HGV’s is therefore a matter that is more properly dealt with in that application. Appraisal of Main Planning Issues (i) Policy issues 13. 14. Preferred Area 12 was designated as such in the MLP following a lengthy Public Inquiry in 1993 at which the issues of the principle and overall suitability of the site for the extraction of sand and gravel were considered. Under MLP Policy 8, there is a presumption in favour of allowing mineral extraction at the site so long as: (a) an acceptable balance is struck between the need for the extraction and all relevant environmental, agricultural, amenity and other relevant planning considerations; (b) the details of the proposal requirements of the Plan; and (c) the proposal has full regard to the detailed requirements for the individual Preferred Areas as set out in the MLP. satisfy the other detailed The JSPU has raised no objection to the need to extract the minerals from the application site. Their comments on application 06/00588 (also reported on this agenda) indicate that there is a need for further planning permissions for mineral extraction in the Berkshire area in order to maintain the land bank at the appropriate level derived from national and regional policies. This same argument would also apply to the present application site. 15. The MLP contains an extensive set of detailed requirements for Preferred Area 12 that are designed to ensure that proper account is taken of all the relevant environmental and other issues relating to the extraction of sand and gravel from the site. They are grouped under headings that approximately match the list of main planning issues identified above. 16. The policy issues include consideration of those designed to minimise the wider impact of mineral extraction in an area where other permitted extraction sites already exist. In particular, the MLP seeks to ensure that working does not take place simultaneously on land within Preferred Area 12 which lies immediately south of the village; that working of Preferred Area 12 would not unreasonably prolong extraction and restoration operations at the existing Kingsmead site; and that not more than one active mineral extraction operation will be permitted within Preferred Area 12 at any one time. 17. None of these three issues is directly addressed in the current submission. Potentially the most significant may be the last of the three, given that the Council is now currently faced with two separate new applications for working within Preferred Area 12, and both looking to commence extraction without delay. These two applications are from separate mineral companies and reflect the differences in land ownership within Preferred Area 12. It is understood from discussion with the applicants that they consider the two applications to be capable of being worked independently of one another and that there is no realistic prospect at this time of securing a unified scheme for the working of Preferred Area 12 as a single scheme. 18. The applicant has been invited to make submissions as to why they consider that the MLP provisions regarding only one active working in Preferred Area 12 should be set aside, or alternatively why extraction from their part of the site should be given precedence over extraction from the other. The same invitation has also been made to the applicant in the eastern part of Preferred Area 12 on land to the east of Horton Road under application ref. 06/00588. To date no such submissions have been received from either applicant and therefore the Council needs to make a judgement, if it is able to, on whether the cumulative impact of two separate minerals workings operating concurrently would have a significantly harmful impact. 19. The Joint Strategic Planning Unit has raised no issue concerning the proposal to restore the site using inert waste, rather than using noninert waste, which could be allowed under the provision of the WLP. (ii) The availability of inert infill material 20. With increasing pressure to recycle inert wastes (such as construction and demolition wastes) that might be suitable for infilling the site after the sand and gravel has been extracted, difficulties have been experienced elsewhere in maintaining progressive restoration at rates that keep apace with the progress of extraction. The result can be that the un-restored areas within a mineral site can get ever larger with the progress of site restoration, and hence the period of disturbance to the local environment and to local residents, lagging behind and lasting considerably longer than was originally envisaged. The applicants have therefore been asked to give details of the availability of inert infill material in the quantities needed to ensure that restoration of this site can be maintained at a satisfactory rate. (iii) 21. Cumulative impact The application as submitted does not address in detail the potential cumulative impacts of the scheme when taken together with the potential extraction from the land immediately to the west on land to the east of Horton Road and the permitted extraction at Kingsmead to the south. (iv) Drainage and flooding issues 22. The Environment Agency has raised an objection to the proposal on the grounds that insufficient information has been provided to allow them to assess it fully. In addition, Slough Borough Council has raised an extensive list of concerns relating to drainage, hydrololgical and hydrogeological matters and the RBWM Drainage Officer has also expressed concerns on certain matters under this heading. 23. The applicants have offered to address the concerns raised and in February 2006 they submitted a response to the matters raised by the Environment Agency. It was agreed with the applicants that this response would not be put to the Environment Agency until further clarification had been provided by the applicants regarding the related matters raised by Slough Borough Council and the RBWM Drainage Officer. To date this further clarification has not been received. (v) Noise, dust, pollution and other impacts on Horton and Colnbrook residents 24. The proximity of the site to Horton and Colnbrook means that it is important that the interests of residents and others in the village are appropriately safeguarded. The Environment Protection Officer has raised no objection to the application subject to the imposition of conditions to address noise and dust issues. A number of other issues have also been raised with the applicants, notably concerning visual and landscape matters, but also over dust controls. The applicants have agreed in principle to supply additional information on these matters but to date they have not done so. (vi) 25. Planting and restoration Issues have also been raised with the applicant concerning the details of the proposed planting and restoration, including the scope for planting additional hedgerows and trees at appropriate locations on the western and northern boundaries of the site both before extraction takes place and as part of the restoration of the site. The applicant has in addition been advised of the comments made by consultees concerning the provision of new rights of way as part of the restoration scheme and to the possible need for contingency restoration measures if it lags behind extraction. However, no further information on these matters has been forthcoming from the applicant. Other matters 26. Whilst this application was submitted in December 2004, it was not until August 2005 that the final response was received from the statutory consultees. It was at this time point the applicant was advised of all the issues raised by the consultees so that these could be addressed through the submission of further information. In September 2005 the applicant responded and indicated that they were willing of supply further information on the wide range of issues raised. Their letter included the following statement: “In conclusion, I note that there are a number of issues upon which further information and clarification is required but, in principle, none of these issues appear to be incapable of being addressed via the submission of further information to supplement the existing ES (Environmental Statement). That information can be provided in advance of the determination of the current application ….I will therefore revert to you when the additional information has been assembled.” 27. Little more was heard from the applicant until February 2006 when a hydrological report was submitted. A meeting with the applicants on 8th February 2006 reviewed the matters on which further information was awaited (which included hydrological matters that were not covered in the submitted report), and at which the applicants again indicated their willingness to supply that information. A letter from the applicant dated 24 March 2005 confirmed this. 28. At the time of drafting this report, apart from establishing that a survey for the presence or otherwise of Great Crested Newts is not required, none of the matters raised with the applicant has been advanced. 29. The application has therefore been before this Council for some 18 months but there has been very little progress in resolving the numerous outstanding issues that were notified to the applicant some 10 months ago (in August 2005) or in progressing matters in the manner agreed by the applicant 4 months ago (in February 2006). Given this absence of progress and the inclusion of application 06/00588 on this agenda, together with the common issues with the applications, it was considered that both applications ought to be determined together. Conclusions 30. This report reveals that there remain a large number of important issues on which the applicant’s have failed to satisfy the Council as to the acceptability of the application. 31. In the circumstances, the applicants have been invited to withdraw the application in its present form, to allow time for all the outstanding issues to be fully addressed before a revised version of the application is prepared. At the time of preparing this report the application had not been withdrawn. It is therefore concluded that the appropriate way forward is to refuse the application as currently submitted on the basis of the inadequacy of the information provided. Recommendation: That, subject to the additional comments of the Highway Officer, the application be refused for the following reason: Conditions and Reasons ^CR;; 1 In the opinion of the Local Planning Authority insufficient information has been submitted to demonstrate that the proposal accords with relevant development plan policies, and in particular Policies M2 and M5 of the Berkshire Structure Plan 2001-2016 (Adopted in July 2005) and Policy 8 of the Minerals Local Plan for Berkshire 2001, such that (a) the Local Planning Authority is not convinced that more than one active mineral extraction operation in Preferred Area 12 ought to be permitted at any one time as the cumulative environmental impacts, including consideration of those in connection with the operation of the mineral extraction at the land to the east of Horton Road under planning application 06/00588, and the permitted extraction at Kingsmead, have not been addressed in the Environmental Statement and remain uncertain (b) the Local Planning Authority is not convinced that the provision of sufficient quantities of inert waste for infilling the site after the sand and gravel has been extracted has been demonstrated to enable progressive restoration of the site at a rate that would keep apace with the progress of extraction from the site. This could result in the period of disturbance to the local environment and to local residents lasting considerably longer than is envisaged in the application the Local Planning Authority is not convinced that the proposal will not have a significant adverse impact on drainage, groundwater levels and flooding in the area, and on an underground water supply tunnel routed across the site; and (c) (d) the Local Planning Authority is not convinced that sufficient consideration has been given to the visual and landscape screening of the proposal and to the impact of dust in the area.
