ENVIRONMENTAL RISK MANAGEMENT AUTHORITY DECISION Amended under Section 67A of the HSNO Act on 22 December 2008 14 August 2008 Application Code HSR08024 Application Type To import or manufacture for release any hazardous substance under Section 28 of the Hazardous Substances and New Organisms Act 1996 (“the Act”) Applicant Elanco Animal Health Date Application Received 31 March 2008 Submission Period 21 April 2008 to 04 June 2008 Consideration Date 6 August 2008 To be considered by A Committee of the Authority (“the Committee”) Purpose of the Application To import and manufacture NZCA4222 as an insecticide tablet to treat and prevent ectoparasites on dogs. (Category A). 1 Summary of decision 1.1 The application to import or manufacture NZCA4222 for release is approved with controls in accordance with the relevant provisions of the Act, the HSNO Regulations and the HSNO (Methodology) Order 1998 (“the Methodology”). 1.2 The substance has been given the following unique identifier for the ERMA New Zealand Hazardous Substances Register: NZCA4222 2 Legislative criteria for application 2.1 The application was lodged pursuant to section 28. The decision was determined in accordance with section 29, taking into account matters to be considered in that section and additional matters specified under 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. Unless otherwise stated, references to clauses in this decision refer to clauses of the Methodology. 3 Application process 3.1 The application was formally received on 31 March 2008. 3.2 In accordance with sections 53(1) and 53A, and clauses 2(2)(b) and 7, public notification was made on 21 April 2008. 3.3 Submissions closed on 4 June 2008. 3.4 Various Government departments, Crown Entities and interested parties, including the New Zealand Food Safety Authority (Agricultural Compounds and Veterinary Medicines (ACVM) Group), the Ministry of Health and the Department of Labour Work Place Group, which in the opinion of the Authority would be likely to have an interest in the application, were notified of the receipt of the application (sections 53(4) and 58(1)(c), and clauses 2(2)(e) and 5) and provided with an opportunity to comment or make a public submission on the application. 3.4.1 No submissions were received. 3.5 The Agency was commissioned to prepare an Evaluation and Review Report (“the E&R Report”) to aid the Committee in its decision making process. The E&R Report consists of the Agency’s review of the application and available data regarding the substance and/or its constituent components. In the E&R Report, the Agency proposed a suite of controls considered suitable to manage the risks associated with the release of NZCA4222 and has assessed the potential risks the substance may pose to the environment, human health, Māori, community and to the market economy. 3.6 The ACVM Group, the Ministry of Health, the Department of Labour and the applicant were given the opportunity to comment on the Agency’s Evaluation and Review Report (“the E&R Report”) and the controls proposed therein. The applicant indicated that they did not believe any of the controls to be impracticable or inappropriate. 3.7 No external experts were used in the consideration of this application (clause 17). 3.8 Due to delays in completing the E&R Report, the Authority, with the applicant’s consent, postponed the consideration of the application until 6 August 2008. 3.9 The following members of the Authority considered the application (section 19(2)(b)): Dr Deborah Read(Chair), Dr Kieran Elborough and Dr Shaun Ogilvie . 3.10 The information available to the Committee comprised: the application; and the E&R Report including confidential appendices( with full formulation data). ERMA New Zealand Decision: Application HSR08024 Page 2 of 14 4 Consideration Purpose of the application 4.1 The purpose of the application is to import or manufacture NZCA4222 as an insecticide tablet to treat and prevent ectoparasites on dogs. NZCA4222 contains an active ingredient that is contained in currently approved veterinary medicine and pesticide formulations 4.2 The product is formulated as a tablet and is administered orally. The dose rate is one tablet monthly. Sequence of the consideration. 4.3 In accordance with clause 24, the approach to the consideration adopted by the Committee was to: establish the hazard classifications for the substances and derive the default controls that are prescribed under section 77 for each classification. identify potentially non-negligible risks, costs, and benefits. assess the potentially non-negligible risks and costs. Risks were assessed in accordance with clause 12, and costs in accordance with clause 13. consider the adequacy of the default controls, prescribed under section 77, and exposure limits alongside the assessment of risks and costs to determine whether those controls or limits should be varied or set and identify where additional controls need to be applied, under section 77A, to mitigate any unacceptable risks. vary and add controls in accordance with sections 77 and 77A. undertake a combined consideration of all the risks and costs and determine whether the combined risks and costs are negligible or nonnegligible. The combined risks and costs for this application were determined to be negligible. consider the cost-effectiveness of the application of controls in accordance with clause 35 and sections 77 and 77A. determine whether it was evident that the identified potential benefits outweighed the costs. confirm and set the controls. approve or decline the application under section 29 and clause 26 Hazard classification 4.4 The Agency has classified NZCA4222 as follows: Hazardous Property NZCA4222 Target Organ Toxicity 6.9B Aquatic Ecotoxicity 9.1A Ecotoxicity to terrestrial invertebrates 9.4A ERMA New Zealand Decision: Application HSR08024 Page 3 of 14 Default controls 4.5 In the E&R Report, the Agency assigned default controls for NZCA4222 based on its hazardous properties as set out in the HSNO Regulations. The default controls were used as a reference for evaluation of the application in the E&R Report. The default controls are listed in section 8 of the E&R Report and have not been reproduced here. Identification of the potentially non-negligible risks, costs and benefits of the substance 4.6 In its evaluation of NZCA4222 the Agency identified potentially significant, and therefore non-negligible, risks, costs and benefits associated with the substance. Potentially non-negligible risks 4.7 The Agency considers that the risks associated with NZCA4222 that are potentially non-negligible relate to the substance’s toxic and ecotoxic properties. Potentially non-negligible costs 4.8 A “cost” is defined in Regulation 2 of the Methodology as “the value of a particular adverse effect expressed in monetary or non-monetary terms”. Accordingly, the costs were assessed in an integrated fashion together with the risks in the Agency’s assessment. Potentially non-negligible benefits 4.9 A “benefit” is defined in Regulation 2 of the Methodology as “the value of a particular positive effect expressed in monetary or non-monetary terms”. Benefits that may arise from any of the matters set out in clauses 9 and 11 were considered in terms of clause 13. 4.10 The Committee considers that NZCA4222 will provide greater choice for consumers when choosing flea control for dogs and contribute to an improvement in public health through the control of ectoparasites on pets. 4.11 Overall, the Committee considers the benefits to be derived from the use of NZCA4222 are potentially non-negligible. Assessment of the potentially non-negligible risks and costs of the substance 4.12 Taking into account the Agency’s assessment of the potentially non-negligible risks and costs associated with NZCA4222 in New Zealand, the Committee considers that the risks to the environment are negligible because: 4.12.1 The solid tablet formulation of NZCA4222 will limit the spread of any spillage and assist in easy recovery of the spilt material during any stage of the lifecycle. ERMA New Zealand Decision: Application HSR08024 Page 4 of 14 4.12.2 4.13 Contamination of the environment with NZCA4222 as metabolised or unmetabolised components in the treated animals excreta will be minimised because: It will be localised to the site of excretion; Only small quantities will be involved ( small quantities will be administered monthly); and The substance is not classified as being ecotoxic to birds or mammals. Taking into account the Agency’s assessment of the potentially non-negligible risks and costs associated with NZCA4222 in New Zealand, the Committee considers that the risks to the health and safety are negligible because: 4.13.1 It is highly improbable that repeated or prolonged exposure will occur as a consequence of an incident occurring where unprotected people are present. 4.13.2 Workers likely to be in contact with large quantities of NZCA4222 will be required to use personal protective clothing and equipment. 4.13.3 Dog owners in the home are unlikely to wear protective clothing while handling the substance but their contact will be brief and infrequent (once monthly). 4.13.4 Disposal by dog owners will involve small quantities of packaging and it will be easy to dispose of safely in accordance with label recommendations. 4.14 Significant adverse impacts on the relationship of Maori to the environment, the market economy and to society and the community are not anticipated with the controlled use of NZCA4222. 4.15 There is no evidence to suggest that the controlled use of NZCA4222 will provide significant risks to New Zealand’s international obligations. 5 Controls 5.1 A number of variations to the default controls for NZCA4222 were proposed in the E&R Report in accordance with clause 35 and sections 77 and 77A. These variations and the setting of exposure limits and applications rates are discussed below. 5.2 Control T1 relates to the requirement to limit public exposure to toxic substances by the setting of Tolerable Exposure Limits (TELs), which are derived from Acceptable Daily Exposure (ADE) values. NZCA4222 does not contain any components that meet the requirement of Regulation 11(1)(a). Therefore, ADEs are not required to be set for any component of this substance, and subsequently no TELs are set. The Committee determines that this control is deleted. ERMA New Zealand Decision: Application HSR08024 Page 5 of 14 5.3 Control T2 relates to the requirement to limit worker exposure to toxic substances by the setting of Workplace Exposure Standards (WESs). The Committee notes that Department of Labour WES values have been set for components F and G and an overseas WES value has been set for component E. However, the conditions of regulation 29(1)(a)1 are not met due to the physical form of the substance as a tablet, therefore the substance is unlikely to become airborne and disperse in air in the form of inspirable or respirable dusts, mists, fumes, gases, or vapours under the temperature and pressure it will be used in. Consequently, the Committee determines that this control is deleted. 5.4 Control E1 relates to the requirements to limit exposure of non-target organisms in the environment through the setting of Environmental Exposure Limits (EELs). However, the use pattern for NZCA4222 means that it is extremely unlikely that the substance will enter the environment in quantities sufficient to present a risk to the environment. To be consistent with control modifications to veterinary medicines at transfer, the Committee determines this control is deleted. 5.5 Control E2 relates to restrictions on use of substances in application areas. The Committee does not consider this control to be relevant to NZCA4222 as it is intended for use as a veterinary medicine. As animals are not included within the definition of application area (land, air, water) and to be consistent with modifications to controls of veterinary medicines at transfer, the Committee therefore considers that this control does not apply. Proposed additional controls 5.6 Under section 77A, the Authority may impose as controls any obligations and restrictions as the Authority thinks fit. Under section 77A(4), the Authority must be satisfied that, against any other specified controls that apply to the substance, (a) the proposed control is more effective in terms of its effect on the management, use and risks of the substance; or (b) the proposed control is more cost-effective in terms of its effect on the management, use and risks of the substance; or (c) the proposed control is more likely to achieve its purpose. 5.7 The Committee notes that the risk assessment has been based solely upon the substance being used as a veterinary medicine but none of the specified (default) controls limit how the substance may be used. Accordingly, the Committee considers that the following control should be applied to NZCA4222 as it will be more effective than the specified controls in terms of their effect on the management, use and risks of the substance (section 77A(4)(a)): “NZCA4222 shall only be used as a veterinary medicine” Proposed modification of controls 5.8 1 Under section 77, the default controls triggered for the substance may be varied. Under section 77(3), controls may be substituted or added. Under section 77(4), Hazardous Substances (Classes 6, 8 and 9 Controls) Regulations 2001 ERMA New Zealand Decision: Application HSR08024 Page 6 of 14 controls may be substituted or deleted. Under section 77(5), where a substance triggers more than one hazard classification, controls may be combined. 5.9 The following modifications are proposed to the default controls for NZCA4222: 5.9.1 Controls T4 and E6 relate to the proper management of equipment used to handle toxic and ecotoxic substances. To be consistent with modifications to controls of veterinary medicines at transfer, the Committee determines that these controls be deleted in accordance with section 77(4)(a) as NZCA4222 is in solid form as a tablet and applied directly to the animal, and consequently the risk of exposure to people or the environment is not considered to be significant. 5.9.2 Control T5 specifies that personal protective clothing and equipment must be employed when NZCA4222 is being handled. The Committee determines that, as the substance is in tablet form, this control should be varied (in accordance with variations made to the transferred veterinary medicines) so as to apply during all stages of the lifecycle with the exception of use. This variation is proposed in accordance with section 77(4)(b). 5.9.3 Control E3 relates to the protection of terrestrial invertebrates (e.g. beneficial insects). As NZCA4222 is in solid form as a tablet and is applied directly to the animal, the Committee considers the risk of exposure to the environment is not significant and proposes that this control not be applied to NZCA4222. This is consistent with modifications to controls of veterinary medicines at transfer. 5.9.4 Control E5 relates to the requirements for keeping records of use of very ecotoxic substances if 3 kg or more is applied within 24 hours in a place where the substance is likely to enter air or water and leave the place. The Committee considers that the oral administration of NZCA4222 is not consistent with these requirements and therefore determines that control E5 is deleted in accordance with section 77(4)(a). 5.9.5 Controls I3 and I11 relate to requirements for priority and secondary identifiers for ecotoxic substances. Control EM7 describes the information which must be provided with ecotoxic substances when held in certain quantities. The Committee considers that these controls should be deleted in accordance with section 77(4)(a) as the substance is administered directly to the animal as a tablet and environmental exposure is very unlikely to occur. 5.9.6 Controls D4 and D5 may be combined in accordance with section 77(5) as they both relate to requirements for disposal of NZCA4222. 5.9.7 Approved handler requirements (control E7 and AH1) have been triggered for NZCA4222 as a result of its 9.1A and 9.4A classifications. The outcome of the ecological risk assessment (refer Appendix 3 and ERMA New Zealand Decision: Application HSR08024 Page 7 of 14 Section 9 of the E&R Report) indicates that it is unlikely there will be any adverse environmental effects from the proposed use of this substance. The Committee therefore determines that the approved handler controls is deleted as provided by section 77(4)(b). 5.10 5.9.8 Tracking requirements (control TR1) have been triggered for NZCA4222 as a result of its 9.1A and 9.4A classifications. However, for substances where the tracking control has been triggered solely as a result of ecotoxicity, it is considered that any risk that may arise during its lifecycle are adequately managed by other controls such as packaging, labeling and emergency management requirements. The Committee therefore determines that the tracking control can be deleted as provided by section 77(4)(b). 5.9.9 Control I16 relates to the requirements for secondary identifiers for toxic substances (Regulation 25 of the Hazardous Substances (Identification) Regulations 2001). The applicant wished to modify this control so that target organ information was not required on labeling. The Committee considers that NZCA4222 is packaged in quantities small enough that a human would have to have repeated access to multiple packets over a long period of time to suffer chronic effects. The Committee therefore determines that Clauses 25(a) to 25(d) of the Hazardous Substances (Identification Regulations 2001) are deleted in accordance with section 67A (under the category of minor in effect as there is no increase in residual risk). Control I16 (Regulation 25 of the Hazardous Substances (Identification) Regulations 2001) includes a requirement to identify certain toxic components on product labels. The Committee, consistent with the guidance provided by the Global Harmonised System (GHS), considers that regulation 25(e) should be varied such that the concentration cut-offs that apply to a component with a hazard classification of 6.5, 6.6, 6.7, 6.8 or 6.9, for the purpose of triggering this requirement, should be as follows: HSNO Classification 6.5A, 6.5B, 6.6A, 6.7A 6.6B 6.7B 6.8A, 6.8C 6.8B 6.9A, 6.9B Cut-off for label (% w/w) 0.1 1 1 0.3 3 10 Cut-off for SDS (% w/w) 0.1 1 0.1 0.1 0.1 1 5.11 The applicant was given an opportunity to comment on the proposed controls as set out in the E&R Report (clause 35(b)). 5.12 In response, the applicant indicated that they did not believe any of the controls to be impracticable or inappropriate. ERMA New Zealand Decision: Application HSR08024 Page 8 of 14 6 Overall evaluation of risks and costs 6.1 On the basis of the risk assessment, and taking into account the controls imposed, including the additional controls set under section 77A, the Committee considers that NZCA4222 poses negligible risks to the environment and to human health. 7 Review of controls for cost-effectiveness 7.1 The Committee considers that the proposed controls are the most cost-effective means of managing the identified potential risks and costs associated with this application in accordance with clause 35(a) and sections 77 and 77A. 7.2 The applicant was given an opportunity to comment on the proposed controls as set out in the E&R Report (clause 35(b)). The applicant’s comments were taken into account during the consideration of the application 8 Comparison of risks, cost and benefits 8.1 As the Committee considers that the risks to the environment and human health are negligible with the controls in place, clause 26 applies and the Committee may approve the manufacture or import for release of NZCA4222 if it is evident that the benefits associated with the substances outweigh the costs. 8.2 As there are potentially non-negligible benefits associated with the import or manufacture of NZCA4222, the Committee is satisfied that it is evident that the benefits associated with the substances outweigh the costs 9 Recommendations 9.1 The Committee recommends that, should inappropriate or accidental use, transport or disposal of NZCA4222 result in the contamination of waterways, the appropriate authorities, including the relevant iwi authorities in the region, should be notified. This action should include advising them of the contamination and the measures taken in response. 10 Environmental User Charges 10.1 The Committee considers that the application of controls to NZCA4222 will provide an effective means of managing risks associated with this substance. At this time no consideration has been given to whether or not environmental charges should be applied to this substance as an alternative or additional means of achieving effective risk management. 11 Decision 11.1 The Committee determines that NZCA4222 should be classified as follows: • 6.9B target organ toxicity ERMA New Zealand Decision: Application HSR08024 Page 9 of 14 • • 9.1A aquatic toxicity 9.4A terrestrial invertebrate ecotoxicity. 11.2 Pursuant to section 29 and clause 26, the Committee is satisfied that the positive effects (benefits) of the substance outweigh the adverse effects (risks and costs). 11.3 The application for importation or manufacture and release of the hazardous substance NZCA4222, is thus approved with controls as listed in Appendix 1. 11.4 In accordance with clause 36(2) (b), the Committee records that, in reaching this conclusion, it has applied the balancing tests in section 29 and clause 26. 11.5 It has also applied the following criteria in the Methodology: clause 9 – equivalent of sections 5, 6 and 8; clause 11 – characteristics of substance; clause 12 – evaluation of assessment of risks; clause 13 – evaluation of assessment of costs and benefits; clause 14 – costs and benefits accruing to New Zealand clause 21 – the decision accords with the requirements 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 33 – risk characteristics; clause 34 – the aggregation and comparison of risks, costs and benefits; and clause 35 – the costs and benefits of varying the default controls. signed Date: 14 August 2008 Chair Dr Deborah Read ERMA NZ Approval Code: HSR007957 ERMA New Zealand Decision: Application HSR08024 Page 10 of 14 Amendment December 2008 Control I16 applies Regulation 25 of the Hazardous Substances (Identification) Regulations 2001 to a substance. This control relates to secondary identifiers for toxic substances and required the applicant to have target organ information on labelling. Control I16 has been modified for NZCA4222 so that target organ information on labelling is not required. Paragraph 5.9.9 has been added to the decision and reads as follows: Control I16 relates to the requirements for secondary identifiers for toxic substances (Regulation 25 of the Hazardous Substances (Identification) Regulations 2001). The applicant wished to modify this control so that target organ information was not required on labeling. The Committee considers that NZCA4222 is packaged in quantities small enough that a human would have to have repeated access to multiple packets over a long period of time to suffer chronic effects. The Committee therefore determines that Clauses 25(a) to 25(d) of the Hazardous Substances (Identification Regulations 2001) are deleted in accordance with section 67A (under the category of minor in effect as there is no increase in residual risk). This change has been completed under section 67A as the change is considered minor in effect as there is no increase in residual risk.
