ENVIRONMENTAL RISK MANAGEMENT AUTHORITY DECISION Date Signed: 21 February 2007 Application code: NOC06011 Application category: Import into Containment any New Organism under section 40(1)(a) of the Hazardous Substances and New Organisms (HSNO) Act 1996 Applicant: Hamilton Zoo Purpose: Importation of fishing cats (Prionailurus viverrinus, Bennett 1833) into containment at Hamilton Zoo, and potentially other zoos in the future, to aid conservation through display and captive breeding Date application received: 11 January 2007 Date of consideration 21 February 2007 Considered by: A Committee of the Authority 1 Summary of Decision 1.1 The application to import into containment fishing cats Prionailurus viverrinus (Bennett 1833) (Family: Felidae) is approved, with controls, having being considered in accordance with the relevant provisions of the Hazardous Substances and New Organisms Act 1996 (the Act) and the HSNO (Methodology) Order 1998 (the Methodology). 2 Legislative Criteria Legislative Criteria for Application 2.1 The application was lodged pursuant to section 40(1)(a) of the Act. The application was determined in accordance with section 45, having regard to the matters specified in section 44 and 37 and other matters relevant to the purpose of the Act, as specified in Part II of the Act. Unless otherwise stated, references to section numbers in this decision refer to sections of the Act. 2.2 Consideration of the application followed the relevant provisions of the Methodology, as specified in more detail below. Unless otherwise stated, references to clause numbers in this decision refer to clauses of the Methodology. 3 Application Process Application Receipt 3.1 Application NOC06011 was determined to be in compliance with section 40(2) of the Act and was formally received on 11 January 2007. Environmental Risk Management Authority Decision: Application NOC06011 Page 1 of 25 Notification 3.2 Under section 53(2) of the Act the Environmental Risk Management Authority (the Authority) has discretion as to whether to publicly notify an application to import into containment any new organism. In this case the application was not publicly notified (following ERMA New Zealand guidelines) because the importation into containment for public display and captive breeding of conventional vertebrate zoo animals is not expected to be of significant public interest. The fishing cats meet this criterion and no exceptional circumstances exist. 3.3 In accordance with section 58(1)(c) of the Act and clauses 2(2)(e) and 5 of the Methodology, the Department of Conservation (DoC) and the Ministry of Agriculture and Forestry (MAF) Biosecurity New Zealand were notified and provided with an opportunity to comment on the application. Neither of the agencies raised any issues with the application. Decision Making Committee 3.4 The application was considered by a sub-Committee of the New Organism (Non GMO) Committee of the Authority appointed in accordance with section 19(2)(b) of the Act. The Committee comprised of the following members: Dr Max Suckling (Chair), Dr Manuka Henare and Helen Atkins. Information Available for Consideration 3.5 The documents available for the consideration of the application by the Committee were: Application NOC06011 (Form NO2N). Appendices attached to the application. Notes for the Committee to assist and support the Committee’s decision making. 3.6 Recognised techniques were used in identifying, assessing, and evaluating the relevant information, as required under clause 24 of the Methodology. Techniques for identifying and preparing information on risks, costs and benefits were based on internal procedures as specified in the ERMA New Zealand Technical Guide publications. 4 Sequence of the Consideration 4.1 In accordance with clause 24 of the Methodology, the approach to the consideration adopted by the Committee was to first examine the scope and purpose of the application, and the organisms applied for, then to look sequentially at identification, assessment and evaluation of risks, costs and benefits. Those risks identified as potentially significant were assessed in accordance with clause 12 of the Methodology. Costs and benefits were assessed in accordance with clause 13 of the Methodology. Qualitative scales used by the Committee to measure likelihood and magnitude of risks, costs and benefits are provided in Appendix 2 of this decision. Environmental Risk Management Authority Decision: Application NOC06011 Page 2 of 25 4.2 Interposed with the assessment of risks, costs and benefits was the consideration of the adequacy of the proposed containment regime, and the ability of the organisms to escape and establish self-sustaining populations (as required by sections 37 and 44 and clause 10(e)). Management techniques were considered in relation to the identified risks. The containment regime was considered in the context of a risk management regime for controlling the identified risks and costs (clauses 12(d) and 24). In doing so, the Committee set controls to satisfactorily provide for the matters in the Third Schedule (Part II) of the Act and additional controls were considered in relation to residual risks that required further consideration. 4.3 Benefits associated with this application were considered in accordance with clauses 9, 10, 13 and 14 of the Methodology and section 6(e) of the Act. 4.4 Finally, taking account of the risk characteristics established in accordance with clause 33 of the Methodology, the combined impact of risks, costs and benefits was evaluated in accordance with clause 34. The approach to the consideration follows the decision path outlined in Appendix 3 of this decision. 5 Purpose of the Application 5.1 Hamilton Zoo wishes to import fishing cats Prionailurus viverrinus (Bennett 1833) (Family: Felidae) into containment for public display and for captive breeding. Fishing cats are CITES Appendix II1 species and the importation of such animals will allow Hamilton Zoo to contribute to international conservation efforts by: participating in international captive breeding programmes; enhancing staff skills in felid husbandry; and enhancing public awareness of the conservation programmes for vulnerable, endangered or at risk animals. The increased gate revenues expected from increased numbers of visitors will also enable the zoo to contribute towards other conservation programmes for endangered or native animals. 5.2 In accordance with section 45(1)(a)(i) of the Act, the Committee determined that this application was for a valid purpose within the scope of section 39(1)(e) of the Act being the public display of any organism including, but not limited to, display in a circus or zoological garden. 6 Adequacy of Containment Regime 6.1 In carrying out its consideration the Committee considered the adequacy of containment in accordance with section 45(1)(a)(iii) of the Act, and the magnitude and likelihood of the risks, costs and benefits alongside each other and in an integrated fashion. This is because the former interact with the latter and this is recognised in clause 12(d) of the Methodology and in section 45(1)(a)(ii) of the Act. For convenience in setting out the decision the adequacy of containment is discussed first. CITES Appendix II includes vulnerable species in which trade must be controlled in order to avoid utilisation incompatible with their survival. 1 Environmental Risk Management Authority Decision: Application NOC06011 Page 3 of 25 Ability to adequately contain the organisms 6.2 In considering the adequacy of the containment regime and the ability of the organisms to escape from containment, the Committee considered the following: i. the biological characteristics of the organisms; ii. the containment regime; and iii. potential pathways for escape of the organisms from the containment facility. i. Biological characteristics of the organism 6.3 Fishing cats are powerful sturdily built cats that are brownish grey in colour with black spots on their bodies that can merge to form stripes on the face, neck and back. The average length and weight of a fishing cat is 67cm, 6 kg for females and 72cm, 15 kg for males respectively. Fishing cats reach adult size at approximately 8 months and sexual maturity at 18 months. 6.4 Fishing cats are native to specific regions of Asia including India and Nepal. Fishing cats are adapted to the wetland environment and are typically found in areas of dense vegetation near slow-moving water for example small streams, marshy thickets and swamp margins. Unlike most felines, fishing cats are not fearful of water and are strong swimmers in deep water and over long distances. Fishing cats have been known to dive into the water while hunting and have been known to remain submerged to capture surface-dwelling prey such as water fowl. Fishing cats have not been observed to have notable climbing or jumping abilities. 6.5 The diet of the fishing cat primarily consists of fish but these animals will also feed on other water-based species such as birds. Fishing cats are opportunistic hunters and on land can hunt small mammals such as rats, wild pigs and goats. ii. Containment regime 6.6 The MAF/ERMA New Zealand Standard 154.03.04: Containment Facilities for Zoo Animals has a specific schedule (Carnivores C1: Felids and Ursidae (excluding cheetah)) in Schedule 1, which details the physical containment and operational procedure required to contain the animal given its physical abilities and behavioural factors. The standard requires the facility’s containment manual to be updated to demonstrate how the physical construction of the facility and the operational procedures will contain the new species, and contingency plans for recovery should any escapes occur. The Committee notes that fishing cats have been successfully kept in containment in overseas zoos. The Committee also notes that Hamilton Zoo currently holds other felids, including the Asiatic golden cat, leopard cat and bobcat in similar enclosures with no breaches of containment at this time. iii. Potential pathways for escape of organisms from the containment facility 6.7 The Committee considered the potential pathways of escape of fishing cats as: escape during transport to containment facilities; accidental or deliberate escape from enclosure within the containment facility; Environmental Risk Management Authority Decision: Application NOC06011 Page 4 of 25 6.8 escape due to accidental/unintentional or deliberate removal by people (during their containment at the zoo); and escape from containment following natural disaster (such as flood, earthquake) or fire. The Committee concluded that escape of the organism via any of these pathways is highly improbable. This conclusion was formed on the basis of the provisions of the containment standard 154.03.04 which requires measures to be taken to prevent escape by any of these pathways. No additional controls were considered necessary to ensure the containment of the fishing cats. Conclusion on adequacy of the containment regime 6.9 The Committee has considered the ability of the fishing cats to escape containment given its biological characteristics, the proposed containment regime and the potential pathways of escape. Taking all of these considerations into account the Committee concludes that it is highly improbable that fishing cats would be able to escape from containment. 6.10 In order to ensure that any subsequent users of the approval have adequate containment regimes, additional control 6.1 (Appendix 1) has been included requiring any person using this approval for the first time to notify ERMA New Zealand and the MAF Inspector responsible for supervision of the facility of their intention to do so in writing. 7 Ability of the Organism to Establish a Self-Sustaining Population 7.1 In accordance with sections 44 and 37 and clause 10(e) the Committee considered the ability of the fishing cats to form self-sustaining populations should they escape containment, and the ease of eradication of such populations. 7.2 In the event of an escape from containment, it is likely that a fishing cat would attempt concealment on the zoo site and this natural caution would assist in the early recapture of any escapees. As captive animals, the fishing cats will be conditioned to approach the keepers for food and would be expected to show high affinity to their enclosure. Therefore, in the highly improbable event of an escape, the escapee could be easily retrieved by zoo staff and returned to containment. 7.3 As fishing cats are adapted to wetland environments, it is expected that these animals may not readily thrive outside of such environments. In the New Zealand environment, wetlands cover less than 2% of New Zealand’s land area (Statistics New Zealand 2006). Therefore even in the highly improbable event of escape from containment, due to the limited availability of this favoured wetland habitat in New Zealand it is highly improbable that an escaped fishing cat would find an appropriate habitat to survive and thrive. 7.4 Taking into account the ease of recapture and the limited availability of suitable habitats, in event of escape the Committee considers the establishment of a selfsustaining population is highly improbable. Environmental Risk Management Authority Decision: Application NOC06011 Page 5 of 25 8 Identification and assessment of potentially significant adverse effects (risks and costs) 8.1 In accordance with clause 9(c) the Committee has categorised potential adverse effects into environmental, human health, Māori culture, market economy and social categories. These adverse effects have been considered in terms of the requirements of clauses 12, 13, and 14 including the probability of occurrence and the magnitude of adverse effects, whether or not they are monetary, and the distribution of costs and benefits over time, space and groups in the community. Risk characteristics are considered in terms of clause 33. The degree of uncertainty attached to evidence is taken into account, as required under clauses 25, 29 and 30. The Environment 8.2 Fishing cats are a wetland species whose diet primarily consists of water-based organisms such as fish and birds. In the highly improbable event of an escape and equally highly improbable event of a self-sustaining population establishing in the wild, local adverse effects on the New Zealand biota as well as the immediate ecosystem is possible. However, due to the limited availability of the favoured wetland habitat in New Zealand and taking into account the ease of recapture, any effects are likely to be localised and of short term duration. The magnitude of effect is therefore considered to be minimal to minor, and the long term establishment of an undesirable self sustaining population in the wild is considered highly improbable. The Committee concludes the potential adverse effects on the environment are negligible. Human Health and Safety 8.3 The Committee noted that although small felids generally avoid direct confrontation, fishing cats may show aggression to humans when feeling threatened. As the general public will not have direct access to the fishing cats and the handling procedures by staff with the animals is detailed in the containment manual, the Committee concludes the potential adverse effects on public and occupational human health and safety to be negligible. Māori and their Culture and Traditions 8.4 The Committee has considered the potential Māori cultural effects in accordance with clauses 9(b)(i) and 9(c)(iv) and sections 6(d) and 8 of the Act using the assessment framework contained in the ERMA New Zealand User Guide “Working with Māori under the HSNO Act 1996” in assessing this application. 8.5 Fishing cats would need to first escape from containment and then successfully establish a self sustaining population before any negative impacts upon the native biota could occur. If this chain of events did eventuate then fishing cats could have adverse effects on the mauri of native ecosystems. However, as concluded previously it is highly improbable that these species of fishing cats will escape containment and/or establish a population without detection. In the short time that escaped fishing cats remain at large the magnitude of any impact on mauri is considered to be negligible. Environmental Risk Management Authority Decision: Application NOC06011 Page 6 of 25 8.6 Therefore, due to the highly improbable nature of possible escape the Committee considers the potential adverse effect on the mauri of native ecosystems and therefore to Māori from the importation into containment of fishing cats into Hamilton Zoo and/or similar containment facilities in New Zealand to be negligible. The Market Economy 8.7 The Committee considered the information available and did not identify any adverse effects to the market economy. Society and Communities 8.8 The Committee considered the information available and did not identify any adverse effects to society and the community. 9 Identification and assessment of potentially significant beneficial effects 9.1 The Committee considered the potential beneficial effects associated with the application, in accordance with sections 5 and 6(e) of the Act and clauses 9(c), 10, 13, and 14 of the Methodology. The Committee identified the following beneficial effects: The Environment 9.2 The development of a self-sustaining population will maintain fishing cats in captivity which will aid in the conservation of this vulnerable species. The Committee considered this benefit of minor to moderate value and likely to be realised and therefore non-negligible. Society and communities The increased numbers of visitors to zoos will result in the education of the public and enhanced generation of revenue which can be used for additional conservation efforts. The enhancement of felid husbandry skills of staff. 9.3 The Committee considered these benefits of minor to moderate value and likely to be realised and therefore non-negligible. 10 Establishment of the Approach to Risk in the Light of Risk Characteristics 10.1 Clause 33 of the Methodology requires the Authority to have regard for the extent to which a specified set of risk characteristics exist when considering applications. This provides a route for determining how cautious or risk averse the Authority should be in weighing up risks and costs against benefits. In the present application clause 33 is influenced by the organisms being “in containment” and the conclusion that the containment provisions and other controls will reduce most biological and physical risks to a low level. Environmental Risk Management Authority Decision: Application NOC06011 Page 7 of 25 10.2 The Committee determined that all identified risks and costs (adverse effects) were individually and collectively assessed as being negligible. Therefore additional caution was not warranted. 11 Associated Approvals 11.1 The Committee noted the need for the applicant to obtain the following associated approvals: An import permit from the Ministry of Agriculture and Forestry which will require adherence to the Import Health Standard to mitigate the risk of any associated organisms. As fishing cats are classed as a CITES Appendix II species, appropriate permits from the country of export are required. 12 Overall Evaluation of Risks, Costs and Benefits 12.1 The overall evaluation of risks, costs and benefits set out below was carried out in accordance with section 45 of the Act and clause 26 of the Methodology, having regard to clauses 22 and 34 of the Methodology. 12.2 The Committee has assessed the potential adverse effects (risks and costs) of importing these organisms into containment as being negligible. 12.3 The Committee considers that the beneficial effects (benefits) are non-negligible. 12.4 The Committee has concluded that the establishment of self-sustaining populations of fishing cats in New Zealand, should they escape, is highly improbable. The proposed containment regime, based on the MAF/ERMA Standard 154.03.04 is considered to be adequate considering the risks posed by the organisms. Additionally, it is considered highly improbable that the organisms would be able to escape from containment. 12.5 The Committee was unable to find common units of measurement with which to combine risks, costs, and benefits in accordance with clause 34(a). There were no dominant sources of risk (clause 34(b)). Because the risks as a whole are negligible the decision is made in accordance with clause 26 (not clause 27) of the Methodology. 12.6 The Committee considered all of the controls, set out in Appendix 1, taking into account the cost effectiveness of the controls in preventing the escape of the organisms and effectively managing any risks. The Committee, having regard to these matters, is satisfied that the organisms can be adequately contained, and that it is evident that the (beneficial effects) benefits of the application outweigh the adverse effects (risks and costs). 13 Decision 13.1 Pursuant to section 45(1)(a)(i) of the Act, the Committee is satisfied that this application is for one of the purposes specified in section 39(1) of the Act, being Environmental Risk Management Authority Decision: Application NOC06011 Page 8 of 25 section 39(1)(e): public display of any organism including, but not limited to, display in circus or zoological garden. 13.2 Having considered all the possible effects in accordance with sections 45(1)(a)(ii), 45(4) and 44 and pursuant to clause 26 of the Methodology, and based on consideration and analysis of the information provided and taking into account the application of risk management controls specified in this decision, the view of the Committee is that the adverse effects (risks and costs) associated with the importation into containment of fishing cats Prionailurus viverrinus (Bennett 1833) are outweighed by the beneficial effects (benefits). 13.3 The Committee is satisfied that the containment regime, as set out in Appendix 1, will adequately contain the organisms as required by section 45(1)(a)(iii) of the Act. 13.4 In accordance with clause 36(2)(b) of the Methodology the Committee records that, in reaching this conclusion, it has applied the balancing tests in section 45 of the Act and clause 26 of the Methodology and has relied in particular on the criteria set out in the following sections of the Act: 13.5 section 44 additional matters to be considered; section 45 determination of application; section 37 additional matters to be considered; and the Third Schedule-Part II, matters to be addressed by containment controls for new organisms. The Committee has also applied the following criteria in the Methodology: clause 9 - equivalent of sections 5, 6 and 8; clause 10 - equivalent of sections 36 and 37; clause 12 – evaluation of assessment of risks; clause 13 – evaluation of assessment of costs and benefits; clause 20 – information produced from other bodies; clause 21 – the decision accords with the requirements of the Act and regulations; clause 22 – the evaluation of risks, costs and benefits – relevant considerations; clause 24 – the use of recognised risk identification, assessment, evaluation and management techniques; clause 25 – the evaluation of risks; clause 26 - the risks are negligible and it is evident benefits outweigh costs; clause 29 and 32 – considering uncertainty; Environmental Risk Management Authority Decision: Application NOC06011 Page 9 of 25 13.6 clause 33 – the risk characteristics; and clause 34 – the aggregation and comparison of risks, costs and benefits. The application to import into containment: fishing cats Prionailurus viverrinus (Bennett 1833) (Family: Felidae) is approved, with controls, in accordance with section 45(1)(a) of the Act. As required under section 45(2) the approval is subject to the controls listed in Appendix 1 of this decision. ___________________________ 21 February 2007 Dr Max Suckling Date Chair, Decision-making Committee of the Authority Approval code: NOC002486 References Statistics New Zealand 2006. http://www.stats.govt.nz/analytical-reports/monitoringprogress/envmt-ecosystem-resilience/land.htm Retrieved January 2007. Environmental Risk Management Authority Decision: Application NOC06011 Page 10 of 25 Appendix 1: Controls Required by this Approval In order to satisfactorily address the matters detailed in the Third Schedule Part II: Containment controls for new organisms excluding genetically modified organisms2, of the Act, and other matters in order to give effect to the purpose of the Act, the approved organisms are subject to the following controls: 1 To limit the likelihood of any accidental release of any organism or any viable genetic material3: 1.1 The construction, operation, and management of the zoo animal containment facility shall be in accordance with the MAF/ERMA New Zealand Standard 154.03.044: Containment Facilities for Zoo Animals. 1.2 The person responsible for the operation of the containment facility shall inform all personnel involved in handling the approved organisms of the Authority’s controls. 1.3 The containment facility and operator shall be approved by Ministry of Agriculture (MAF), in accordance with section 39 of the Biosecurity Act and the MAF/ERMA New Zealand Standard 154.03.04: Containment Facilities for Zoo Animals. 2 To exclude unauthorised people from the facility: 2.1 The identification of entrances, numbers of and access to entrances, and the security requirements for the entrances and the facility shall be in compliance with the standard listed in control 1.1 of this decision. 3 To control the effects of any accidental release or escape of an organism: 3.1 Construction and operation of the containment facility shall comply with the requirements of the standard listed in control 1.1 relating to the control of the effects of any accidental release or escape of an organism. 3.2 If a breach of containment occurs, the facility operator must ensure that the MAF Inspector responsible for supervision of the facility has received notification of the breach within 24 hours. 3.3 In the event of any breach of containment of the organism, the contingency plan for the attempted retrieval or destruction of any viable material of the organism that has escaped Bold heading refer to matters to be addressed by containment controls for new organisms excluding genetically modified organisms, specified in the Third Schedule (Part II) of the HSNO Act 1996. 2 Viable genetic material is biological material that can be resuscitated to grow into tissues or organisms. It can be defined to mean biological material capable of growth even though resuscitation may be required, eg when organisms or parts thereof are sublethally damaged by being frozen, dried, heated, or affected by chemical. 3 Any reference to this standard in these controls refers to any subsequent version approved or endorsed by ERMA New Zealand. 4 Environmental Risk Management Authority Decision: Application NOC06011 Page 11 of 25 shall be implemented immediately. The contingency plan shall be included in the containment manual in accordance with the requirements of standard listed in control 1.1. 3.4 The applicant shall comply with the requirements of the standard listed in control 1.1 above relating to the maintenance of records demonstrating compliance with the standard, as required by the quality assurance programme, and documented in the containment manual. 4 Inspection and monitoring requirements for containment facilities: 4.1 The inspection and monitoring requirements for the containment facility shall be in compliance with the standard listed in control 1.1. 4.2 The Authority, or its authorised agent or properly authorised enforcement officers, may inspect the facilities at any reasonable time. 4.3 The containment manuals should be updated, as necessary, to address the implementation of the controls imposed by this approval, in accordance with the standard listed in control 1.1. 5 Qualifications required of the persons responsible for implementing these controls: 5.1 The training of personnel working in the facility shall be in compliance with the standard listed in control 1.1. 6 Additional controls: 6.1 Any person using this approval for the first time shall notify ERMA New Zealand and the MAF Inspector responsible for supervision of the facility of their intention to do so in writing. Environmental Risk Management Authority Decision: Application NOC06011 Page 12 of 25 Appendix 2: Qualitative scales for describing adverse effects Qualitative Risk Assessment Risks and benefits are assessed by estimating the magnitude of the possible effects and the likelihood of their occurrence. For each effect, the combination of these two components determines the level of that effect, which is a two dimensional concept. Risk assessment may be qualitative or quantitative. Qualitative assessment is informed by quantitative data where this is available. Qualitative matrices are used to prioritise risks (and benefits), and to identify any risks that are unacceptable. The measure of the level of risk (combination of magnitude and likelihood) is specific to the application therefore measures of level of risk should not be compared between applications. However, the measures (descriptors) for different types of risk (human health, ecological etc) should be established so that they represent relative orders of magnitude. Magnitude of effect The magnitude must be a measure of the endpoint (specified by the Act and the Methodology), and is described in terms of the element that might be affected. The magnitude of the effect is not the same as the effect itself. The qualitative descriptors for magnitude of effect are surrogate measures that should be used to gauge the end effect or the ‘what if’ element. Tables 1 and 2 contain generic descriptors for magnitude of adverse effects (risks and costs) and beneficial effects (benefits). These descriptors are examples only, and their generic nature means that it may be difficult to use them in some particular circumstances. They are included here simply to illustrate how qualitative tables may be used to represent levels of risk. Environmental Risk Management Authority Decision: Application NOC06011 Page 13 of 25 Table 1 Magnitude of adverse effect Descriptor Minimal Examples of descriptions Mild reversible short term adverse health effects to individuals in highly localised area Highly localised and contained environmental impact, affecting a few (less than ten) individuals members of communities of flora or fauna, no discernible ecosystem impact Low dollar cost of containment/cleanup/repair (<$5,000) No social disruption5 Minor Mild reversible short term adverse health effects to identified and isolated groups6 Localised and contained reversible environmental impact, some local plant or animal communities temporarily damaged, no discernible ecosystem impact or species damage Dollar cost of containment/cleanup/repair in order of $5,000$50,000 Potential social disruption (community placed on alert) Moderate Minor irreversible health effects to individuals and/or reversible medium term adverse health effects to larger (but surrounding) community (requiring hospitalisation) Measurable long term damage to local plant and animal communities, but no obvious spread beyond defined boundaries, medium term individual ecosystem damage, no species damage Dollar cost of containment/cleanup/repair in order of $50,000$500,000, Some social disruption (e.g. people delayed) 5 The concept of social disruption includes both physical disruption, and perceptions leading to psychological disruption. For example, some chemicals may have nuisance effects (through odour) that result in communities feeling threatened. Note that the reference to ‘groups’ and ‘communities’ in the context of human health effects includes the notion of groups defined by health status. 6 Environmental Risk Management Authority Decision: Application NOC06011 Page 14 of 25 Major Significant irreversible adverse health effects affecting individuals and requiring hospitalisation and/or reversible adverse health effects reaching beyond the immediate community Long term/irreversible damage to localised ecosystem but no species loss Dollar cost of containment/cleanup/repair in order of $500,000$5,000,000 Social disruption to surrounding community, including some evacuations Massive Significant irreversible adverse health effects reaching beyond the immediate community and/or deaths Extensive irreversible ecosystem damage, including species loss Dollar cost of containment/cleanup/repair greater than $5,000,000 Major social disruption with entire surrounding area evacuated and impacts on wider community The economic effects category has been given a surrogate magnitude. This is for demonstration as a means of illustrating the type of magnitudes that might be encountered. Table 2 Magnitude of beneficial effect Descriptor Minimal Examples of descriptions Mild short term positive health effects to individuals in highly localised area Highly localised and contained environmental impact, affecting a few (less than ten) individuals members of communities of flora or fauna, no discernible ecosystem impact Low dollar benefit (<$5,000) No social effect Minor Mild short term beneficial health effects to identified and isolated groups Localised and contained beneficial environmental impact, no discernible ecosystem impact or species damage Dollar benefit in order of $5,000-$50,000 Minor localised community benefit Moderate Minor health benefits to individuals and/or medium term health impacts on larger (but surrounding) community and health status groups Measurable benefit to localised plant and animal communities Environmental Risk Management Authority Decision: Application NOC06011 Page 15 of 25 expected to pertain to medium term.

Major Significant beneficial health effects to localised community and specific groups in wider community Long term benefit to localised ecosystem(s) Dollar benefit in order of $500,000-$5,000,000 Substantial social benefit to surrounding community, and individuals in wider community. Massive Significant long term beneficial health effects to the wider community Long term, wide spread benefits to species and/or ecosystems Dollar benefit greater than $5,000,000 Major social benefit affecting wider community Likelihood of effect occurring Likelihood in this context applies to the composite likelihood of the end effect, and not either to the initiating event, or any one of the intermediary events. It includes: the concept of an initiating event (triggering the hazard), and the exposure pathway that links the source (hazard) and the area of impact (public health, environment, economy, or community). The likelihood term applies specifically to the resulting effect or the final event in the chain, and will be a combination of the likelihood of the initiating event and several intermediary likelihoods7. The frequency or probability solely of the initial incident or hazard event should not be used (as it sometimes is in the safety discipline). The best way to determine the likelihood is to specify and analyse the complete pathway of the “chain of events” from source to the final environmental impact or effect. Each event in the chain is dependent upon the previous event occurring in the first place. Likelihood may be expressed as a frequency or a probability. While frequency is often expressed as a number of events within a given time period, it may also be expressed as the number of events per head of (exposed) population. As a probability the likelihood is dimensionless and refers to the number of events of interest divided by the total number of events (range 0-1). 7 Qualitative event tree analysis may be a useful way of ensuring that all aspects are included. Environmental Risk Management Authority Decision: Application NOC06011 Page 16 of 25 Table 3 Likelihood (adverse effect) Descriptor Description 1 Highly improbable Almost certainly not occurring but cannot be totally ruled out 2 Improbable (remote) Only occurring in very exceptional circumstances. 3 Very unlikely Considered only to occur in very unusual circumstances 4 Unlikely (occasional) Could occur, but is not expected to occur under normal operating conditions. 5 Likely A good chance that it may occur under normal operating conditions. 6 Very likely Expected to occur if all conditions met 7 Extremely likely Almost certain Table 3 provides an example of a set of generic likelihood descriptors for adverse and beneficial effect. Note that when estimating these likelihoods, the impact of default controls should be taken into account. The table is not symmetrical. This is to allow for classification of very low probability adverse effects. In practical terms, where the exposure pathway is complex, it may be conceptually difficult to condense all the information into a single likelihood. For any risk where the likelihood is other than ‘highly improbable’ or ‘improbable’, then an analysis of the pathway should include identifying the ‘critical points’; the aspects that are the most vulnerable, and the elements where controls might be used to ‘cut’ the pathway. Calculating the level of risk Using these qualitative descriptors for magnitude of effect and likelihood of the event occurring, an additional two-way table representing a level of risk (combined likelihood and measure of effect) can be constructed as shown in Table 4, where six levels of effect are allocated: A, B, C, D, E and F. These terms have been used to emphasise that the matrix is a device for determining which risks (benefits) require further analysis to determine their significance in the decision making process. Avoiding labels such as ‘low’, ‘medium’, and ‘high’ removes the aspect of perception. The lowest level (A) may be deemed to be equivalent to ‘insignificant’. In this table ‘A’ is given to three combinations; minimal impact and an occurrence of improbable or highly improbable, and minor impact with a highly improbable occurrence. In some cases where there is high Environmental Risk Management Authority Decision: Application NOC06011 Page 17 of 25 uncertainty it may be preferable to split this category into A1 and A2, where only A1 is deemed to equate to insignificant. For negative effects, the levels are used to show how risks can be reduced by the application of additional controls. Where the table is used for positive effects it may also be possible for controls to be applied to ensure that a particular level of benefit is achieved, but this is not a common approach.

Impact of uncertainty in estimates Uncertainty may be taken into account in two ways. Firstly, when describing a risk a range of descriptors may be used. For example, a risk may be allocated a range of very unlikely- improbable, and minor-major. This would put the range of the risk as B through E. Alternatively, the level of risk (or benefit) may be adjusted after it has been estimated on the grounds of uncertainty.

In both of these cases the organisms having similar risk profiles should be grouped into categories. Each category should be considered separately via the path below. Items 1, 2 & 3: The information that should be reviewed includes the application, the E&R Report and supporting documentation. In addition there may in some cases be information provided by experts and submitters. The review of information should occur in terms of section 40(2) of the Act and the following clauses of the Methodology – 8 (relevance and appropriateness of information), 15 and 16 (submissions), 20 (information from other jurisdictions), and 23 (further information). Additional information may need to be sought under section 52 or 58 of the Act. Item 4: If the applicant is unable to provide sufficient information for consideration then the application is not approved. In these circumstances the Authority may choose to decline the application, or the application may lapse. Item 5: Section 39(1) of the Act specifies the purposes for which the Authority may approve importation of a new organism. Item 6: Clearly identify the scope of the organism description with particular reference to whether the application is generic, or refers to a number of organisms. Item 7: i. Identify risks, costs and benefits The range of risks, costs and benefits to be identified should be that covered by clauses 9 and 10 of the Methodology (sections 5 and 6 of the Act). There are two steps within this part of the process: Step 1: Identify all risks, costs and benefits (adverse and beneficial effects) that can be thought of, to provide a starting position that is as comprehensive as possible. For adverse effects this will require identifying the hazards and pathways. For beneficial effects, this will require identifying the nature, sources, and pathways. Environmental Risk Management Authority Decision: Application NOC06011 Page 20 of 25 Step 2: Undertake a preliminary evaluation of all risks, costs and benefits and remove from further consideration all those that can be readily concluded to be not potentially significant, having regard to the characteristics of the organism and the circumstances of the application. All risks, costs and benefits that are not judged to be potentially significant and which are not carried through to assessment should be documented and a record of why they have not been carried through to assessment maintained. Item 8: Section 45(2) requires the application of controls for all applicable matters specified in the 3rd Schedule. The Authority may consider other controls to give effect to the purpose of the Act. The impact of these controls also needs to be considered. Item 9: Assess risks (and costs) Assess all risks (and costs) identified in Item 7 as being potentially significant. Most of these risks and costs will relate to matters in sections 5 & 6 of the Act. In undertaking this assessment the Authority must take into account the principles of the Treaty of Waitangi (section 8, and clause 9(c)(iv)). The assessment should also consider the following matters listed below that have particular relevance for these types of applications. The ability of the organism to escape from containment (section 44) Although strictly speaking, this requirement applies only to field test applications and not to import or development applications (see section 45(1)(a)(ii)), it is prudent and good practice to consider it anyway. This element must be considered in an integrated way in the assessment process because the ability to escape depends on the containment controls set. Self-sustaining population (section 37). Section 37 of the Act requires the consideration to have regard to the ability of the organism to establish an undesirable self sustaining population and the ease of eradication if it were to establish such a population. Undesirable means (in effect) able to create significant risks. Additional matters Other matters to be considered in the assessment are: the extent to which the risk will be mitigated by the setting of containment and other controls, including the mandatory controls in Environmental Risk Management Authority Decision: Application NOC06011 Page 21 of 25 the Act; and the extent to which the risk will be mitigated by the ability to eradicate the organism if it becomes established. The Methodology The assessment of risks (and costs) should be carried out in accordance with the following clauses of the Methodology - 22 (risks, costs and benefits), 25 (scientific information, uncertainty and other values), 29 to 32 (scientific and technical uncertainty), 12 to 14 (assessment of risks, costs and benefits and relevant risks, costs and benefits), 24 (recognised techniques) and 33 (approach to risk). Each risk (and associated cost) should be assessed individually, considering also the level of risk if containment or other controls fail, as well as the probability of such a failure. The approach to risk and the approach to uncertainty are addressed separately. Although the issue of how risk averse to be and that of dealing with uncertainties are different, in practical terms they are often addressed using similar approaches. The following three steps are not sequential and must be taken together for each risk: Estimate magnitude and likelihood (probability) Estimate the magnitude of the identified adverse effect if it should occur, and the likelihood of it occurring (pathway). In estimating the magnitude of the adverse effect take into account the extent to which the risk might be mitigated by how or whether it might be possible to eradicate the organism if a significant adverse effect eventuated (section 37). The risk characteristics listed below under ‘approach to risk’ will affect the estimate of the magnitude of the effect. When estimating the likelihood of the effect occurring, consider the full pathway, that is, all the possible steps that must occur before the final identified effect is realised. Estimating the likelihood requires combining (multiplying) all of the individual likelihoods for each link in the chain of events. Environmental Risk Management Authority Decision: Application NOC06011 Page 22 of 25 Approach to risk (clause 33) When considering applications, the Authority must have regard to the extent to which the following risk characteristics set out in clause 33 exist: a) Exposure to the risk is involuntary: b) The risk will persist over time: c) The risk is subject to uncontrollable spread and is likely to extend its effects beyond the immediate location of incidence: d) The potential adverse effects are irreversible: e) The risk is not known or understood by the general public and there is little experience or understanding of possible measures for managing the potential adverse effects. Consider each risk in terms of the factors listed and decide whether to be risk averse by giving additional weight to that risk. This may be done as part of estimating the magnitude of the effect or where this is not relevant, it may be done separately. Where the Authority chooses to be risk averse, and there is uncertainty as well, the approach to risk may be consolidated with the approach to uncertainty by adopting a conservative approach such as the worst feasible case scenario. Approach to uncertainty (section 7 and clauses 29-32) Uncertainty For each component (magnitude and likelihood) consider the degree of uncertainty associated with the estimation of each component. In some cases it may be clear that the uncertainty could be reduced by gathering further information (undertaking more scientific tests, or extending the literature search). Before requesting or seeking further information it is important to consider how important the uncertainty is in terms of the decision (clause 29(a) – materiality), and to essentially consider the cost-effectiveness of gathering further information. Environmental Risk Management Authority Decision: Application NOC06011 Page 23 of 25 Another approach to addressing uncertainty is to look at a range of scenarios and consider a best feasible-worst feasible scenario range. However, where there is a large degree of uncertainty, this may not be particularly meaningful for calculating the level of risk. In other cases, calculating the level of risk for each end of the range may result in a fairly similar level of risk. Where this does not occur, rather than presenting a wide range in the level of risk it may be better to concentrate on analysing why the uncertainty occurs and whether or not there is any obvious way of resolving it. Section 7 of the Act requires the Authority to be cautious where there is scientific and technical uncertainty. Caution may be applied by adopting a conservative approach in assessing risks, for example, adopting the worst feasible case scenario in calculating the level of risk. Additional controls Controls additional to those mandated in section 45(2) of the Act (see item 8) will need to be considered, in order to mitigate risks to whatever level is considered to be appropriate, and to provide adequate containment. Controls need to provide for the matters set out in the 3rd Schedule as well as providing for any other matters that are required to give effect to the purpose of the Act. Item 10: Consider each of the assessed risks in turn and determine whether it is negligible. Take into account the particular characteristics of the organism and the context of the application. Consider also the cumulative effect of the assessed risks. If each of the risks is considered to be negligible, but the risks cumulatively are not negligible, then take the clause 27 path. This may not be relevant to containment applications. At this point the decision path branches. Where all risks are negligible, and the cumulative effect of the risks is considered to be negligible then take the clause 26 option and move to item 11. If one or more of the risks is considered to be non-negligible, or the cumulative sum of the risks is non-negligible, then take the clause 27 option and move to item 13. Item 11: If risks are negligible and there are no external non-negligible costs, then the fact that the application has been submitted is deemed to demonstrate existence of benefit, and no further benefits need be considered. The application can then be approved under clause 26 (via item 12). If risks are negligible, but there are non-negligible external costs then the decision must be made under clause 27 (via items 13 and 14). Environmental Risk Management Authority Decision: Application NOC06011 Page 24 of 25 Item 12: If the organism description was revised in item 15, the considerations in this item should relate to the revised organism description. If, as a result of this consideration, further revision of the organism description is required, the determination as to whether the organism can be adequately contained should be repeated for the new organism description. Item 13: If some of the risks or external costs are non-negligible, or the cumulative sum of the risks and costs is non-negligible then assess the benefits in terms of clause 13 of the Methodology. Estimate the benefits in terms of the magnitude of the beneficial effect if it should occur, and the likelihood of it occurring. As for risks, there may be uncertainty about the benefits and this should be addressed in a similar manner to that described in item 9. Item 14: Weigh up the adverse and beneficial effects (costs, risks and benefits), applying clause 34 of the Methodology (aggregation and dominant effects). While the approach to risk has been considered for each individual risk it should also be applied to a review of the aggregate effect with respect to all risks. A similar approach should be taken to uncertainty, with reference to clause 29(b) (materiality), and section 7 (caution). Item 15: At this step the scope of the organism description for generic applications should be reviewed. If changes are made to the organism description, items 6 to 14 above should be repeated for the revised organism description. Then the weighing up process in this item for the revised organism description should also be repeated. The scope of the organism description has been identified in item 6. This step in the decision-making process confirms the scope of the organism description in such a way that the risk boundaries are defined. Controls have been considered at the earlier stages of the process (items 8, 9, and 12). However, this step confirms and sets the controls. Controls flow from, but are considered in conjunction with, the organism description. If controls are changed at this point, the previous steps from item 7 onwards need to be repeated.
