DECISION 29 June 2012 1. Summary Substance DAPI Application code APP201371 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”) Application sub-type Category A Applicant Bayer New Zealand Limited Purpose of the application To import DAPI for use as a raw material in the manufacture of veterinary medicines for cattle. Date application formally received 17 May 2012 Consideration date 29 June 2012 Considered by The Chief Executive of the Environmental Protection Authority (EPA) Decision Approved with controls Approval code HSR100708 Hazard classifications 6.1C, 6.8C, 6.9A (refer to Table 1, Section 4) 9.1A, 9.2A, 9.3A, 9.4A 2. Background 2.1. DAPI is intended for use as an active ingredient in veterinary formulations for the treatment of parasites in cattle. DAPI is in the form of a white crystalline powder. The applicant has stated DAPI has similarities with the substance abamectin, as both substances belong to the macrocylic lactone family and share similar chemical structures. 2.2. The applicant has described the lifecycle of DAPI as follows: The substance will be sourced and imported from abroad. The substance will be transported to New Zealand either by sea or air freight. Page 2 of 18 Application for approval to import DAPI for release (APP201371) The substance will be used in the manufacture of veterinary medicines according to Good Manufacturing Practice (GMP). The substance will normally be disposed of by use in the manufacture of other substances. In all other cases of disposal, the substance will be disposed of in accordance with the requirements of the Hazardous Substances (Disposal) Regulations 2001 and the Resource Management Act 1991. 2.3. The lifecycle and use of DAPI is expected to be similar to other veterinary medicine active ingredients currently available in New Zealand. DAPI is currently present as an active ingredient in a number of approved formulated veterinary medicines available in New Zealand. 3. Process, consultation and reasons for non-notification 3.1. The application was lodged pursuant to section 28 of the Act. 3.2. The application contained sufficient information for the staff of the EPA (“the staff”) to undertake a full assessment of the substance from a scientific and technical perspective. 3.3. The Department of Labour, the Ministry for Primary Industries (ACVM Group) and the Ministry of Health were advised of the application on 25 May 2012 and invited to comment on it by 1 June 2012. No comments were received. 3.4. In accordance with section 53(2) of the Act, the application was not publicly notified as the staff considered that there was unlikely to be significant public interest in it. This is because there are formulations that contain DAPI as an active ingredient that are already approved for use in New Zealand. In addition, the lifecycle of the substance is restricted to use within a manufacturing facility where exposure to people and the environment will be limited. 4. Hazardous properties 4.1. The staff determined the hazard classification of DAPI based on the information provided by the applicant and other available information as documented in Appendix A. The classifications determined by the staff differ to those submitted by the applicant, as shown in Table 1 below. The difference in the classifications occurred because the applicant used data for abamectin to classify DAPI, whereas the staff used data for DAPI itself. Table 1 Hazard classifications of DAPI as proposed by the applicant and the EPA staff Hazard Endpoint Applicant classification EPA classification Subclass 6.1 Acute toxicity (oral) 6.1B 6.1C Subclass 6.8 Reproductive/ developmental toxicity 6.8B No www.epa.govt.nz Page 3 of 18 Application for approval to import DAPI for release (APP201371) Subclass 6.8 Reproductive/ developmental toxicity (via lactation) 6.8C 6.8C Subclass 6.9 Target organ systemic toxicity 6.9A 6.9A Subclass 9.1 Aquatic ecotoxicity 9.1A 9.1A Subclass 9.2 Soil ecotoxicity 9.2A 9.2A Subclass 9.3 Terrestrial vertebrate ecotoxicity 9.3A 9.3B Subclass 9.4 Terrestrial invertebrate ecotoxicity 9.4A 9.4A 5. Risk and benefit assessment Assessment of risks to human health and the environment 5.1. The lifecycle of DAPI is restricted to use within a manufacturing facility where exposure to people and the environment will be limited. Therefore, the assessment of the risks to human health and the environment has been limited to a qualitative risk assessment. 5.2. The identification and qualitative assessment of the risks to human health and the environment associated with DAPI are set out in Tables 2 and 3 respectively. More information is detailed in Appendix B. Relationship of Māori to the environment 5.3. The staff note that DAPI triggers a number of hazardous properties giving rise to the potential for cultural risk, including the deterioration of the mauri of taonga flora and fauna species, the environment and the general health and well-being of individuals and the community. 5.4. In general, the introduction and use of hazardous substances has the potential to inhibit the ability of iwi/Māori to fulfil their role as kaitiaki, particularly in relation to the guardianship of waterways, given the ecotoxic nature of some substances to aquatic species, and potential risks to the mauri ora of human health under prolonged exposure to some substances. 5.5. The staff consulted with Kaupapa Kura Taiao1(KKT). Based on the information provided, including the limited use pattern and default controls for DAPI, KKT consider that the risks to Māori culture or traditional relationships with ancestral lands, water, sites, wāhi tapu, valued flora and fauna or other taonga are likely to be negligible. 5.6. In addition, there is no evidence to suggest that the controlled use of DAPI will breach the principles of the Treaty of Waitangi 1 Kaupapa Kura Taiao are the EPA’s Maori Policy & Operations Group www.epa.govt.nz Page 4 of 18 Application for approval to import DAPI for release (APP201371) Table 2: Qualitative assessment of human health risks Lifecycle Description Likelihood Magnitude Matrix Comment Level of risk Importation, transport, storage Acute toxicity (oral) Highly improbable Moderate Negligible Workers and bystanders will only be exposed to the substance during this part of the lifecycle in isolated incidents where spillage occurs. HSNO controls (e.g. labels, Safety Data Sheets (SDS)) and adherence to the Land Transport Rule 45001, Civil Aviation Act 1990 and Maritime Transport Act 1994 (as applicable) will apply. Negligible Use Acute toxicity (oral) Highly improbable Moderate Negligible This lifecycle phase will be subject to HSNO requirements for personal protective equipment, packaging, identification, approved handlers and emergency management. In addition the operation of the manufacturing facilities will be subject to the requirements of the Health and Safety in Employment Act 1992 and the manufacturing processes will comply with Good Manufacturing Practice (GMP). Negligible Reproductive/ developmental toxicity via lactation Highly improbable Major Low The staff consider that whilst the chronic toxic properties of this substance could cause major adverse effects, the approved handlers using the substance will have the necessary skills and knowledge to reduce the level risk from low to negligible Negligible Acute toxicity (oral) Highly improbable Moderate Negligible The staff consider that the substance is most likely to be disposed of by use in the formulation of veterinary medicines. In all other cases of disposal, the substance will be disposed of in accordance with the requirements of the Hazardous Substances (Disposal) Regulations 2001 and the Resource Management Act 1991. Negligible Reproductive/ developmental toxicity via lactation Highly improbable Major Low The staff consider that whilst the chronic toxic properties of this substance could cause major adverse effects, the approved handlers disposing of the substance will have the necessary skills and knowledge to reduce the level risk from low to negligible. Negligible Target organ systemic toxicity Disposal Target organ systemic toxicity www.epa.govt.nz Page 5 of 18 Application for approval to import DAPI for release (APP201371) Table 3: Qualitative assessment of risks to the environment Lifecycle Description Likelihood Magnitude Matrix Comment Level of risk Importation, transport and storage Death or adverse effects to aquatic or terrestrial organisms. Highly improbable Minor Negligible The staff consider that given adherence to the HSNO controls (e.g. packaging, identification and emergency management) and the Land Transport Rule 45001, Civil Aviation Act 1990 and Maritime Transport Act 1994 (as applicable) any spill would involve small quantities which would lead to localised effects only. Negligible Use Death or adverse effects to aquatic or terrestrial organisms. Highly improbable Minor Negligible The use of DAPI will be restricted to use within manufacturing facilities. These facilities will be subject to a number of HSNO controls such as emergency management. Negligible Disposal Death or adverse effects to aquatic or terrestrial organisms. Highly improbable Minor Negligible The staff consider that the substance is most likely to be disposed of by use in the formulation of veterinary medicines. In all other cases of disposal, the substance will be disposed of in accordance with the requirements of the Hazardous Substances (Disposal) Regulations 2001 and the Resource Management Act 1991. Negligible www.epa.govt.nz Page 6 of 18 Application for approval to import DAPI for release (APP201371) Assessment of risks to society and the community and the market economy 5.7. The staff did not identify any risks associated with the approval of DAPI to society, communities or the market economy. New Zealand’s international obligations 5.8. The staff did not identify that the approval of DAPI would impact any of the New Zealand international obligations. Overall assessment of risks 5.9. The staff consider that, with controls in place, the risks associated with DAPI are negligible. Identification of benefits 5.10. The ability to import DAPI into New Zealand will provide benefits to the veterinary medicine industry and New Zealand in that it will enable: the manufacture of new products in New Zealand that would have potential for export earnings; the manufacture of products in New Zealand, thus providing manufacturers with financial benefits and a competitive advantage over imported products; and the production of lower cost products that would be of benefit to farmers. The effects of the substance being unavailable 5.11. The staff consider that the likely effects of the substance being unavailable are the inability to manufacture veterinary medicines containing this substance in New Zealand. This causes reliance on imported veterinary medicines that contain this active ingredient which may be more expensive for end-users. Overall assessment of benefits 5.12. The staff are satisfied that the availability of DAPI will provide benefits to New Zealand, as it is likely that it will provide beneficial effects for the veterinary medicine sector. www.epa.govt.nz Page 7 of 18 Application for approval to import DAPI for release (APP201371) 6. Controls 6.1. Based on the hazard classification determined for DAPI (Table 1, Section 4), a set of associated default controls specified by regulations under the Act has been identified by the staff as being applicable to DAPI. The default controls form the basis of the controls set out in Appendix C. Based on the risk assessment, it is considered that the following exposure limits are relevant and that the additional controls set out below should be applied to DAPI. The setting of exposure limits 6.2. Tolerable Exposure Limits (TELs) can be set to control hazardous substances entering the environment in quantities sufficient to present a risk to people. No TELs have been set for DAPI at this time as the level of risk to bystanders is considered negligible. 6.3. The EPA typically adopts Workplace Exposure Standard (WES) values (listed in the Department of Labour’s Workplace Exposure Standards document2) to control exposure in places of work. No WES values have been set by the Department of Labour for DAPI at this time. 6.4. The default controls allow the setting of Environmental Exposure Limits (EELs) to control hazardous substances entering the environment. No EELs are set for DAPI at this time as the level of risk to the environment is considered negligible. The default EEL values have been deleted. 6.5. The default controls require the setting of an application rate for an ecotoxic substance that is to be sprayed on an area of land (or air or water) and for which an EEL has been set. As DAPI is not intended for application to an area of land and no EEL has been set, this control has been deleted. Additional controls 6.6. The staff note that the risk assessment for DAPI has been limited to the intention to use the substance to formulate veterinary medicines. The staff note that none of the default controls limit how the substance may be used. Accordingly, the staff consider that the approval should be restricted to the use of the substance to the manufacture of veterinary medicines. A control has been added under section 77A of the Act to limit the use of DAPI. Variation and deletion of controls 6.7. The default controls for DAPI include a requirement for keeping records of use for substances that are applied for the purpose of causing biocidal action in places where members of the public may be lawfully present or where the substances are likely to enter the air or water and leave the place. The 2 http://www.osh.govt.nz/publications/booklets/wes-dec-2010/wes-dec-2010.pdf www.epa.govt.nz Page 8 of 18 Application for approval to import DAPI for release (APP201371) staff consider this control is not applicable to the intended use pattern of DAPI and therefore can be deleted. 6.8. Given the highly toxic nature of DAPI, the staff consider that it is appropriate to retain the approved handler requirements for the substance, and provide an exception for the transportation of packaged substances by way of a variation to this control. The revised controls are shown in Appendix C. 6.9. The default controls for DAPI include requirements to protect beneficial terrestrial invertebrates (e.g. bees). The staff note that the substance is intended for use in manufacturing facilities where bees and other beneficial terrestrial invertebrates are unlikely to be present. Therefore, this control can be deleted. Review of controls for cost-effectiveness 6.10. The staff consider that the proposed controls are the most cost-effective means of managing the identified potential risks and costs associated with this application. The applicant was given an opportunity to comment on the proposed controls as set out in this decision. The applicant indicated that they accept the proposed controls for the substance. 7. Environmental user charges 7.1. The staff consider that use of controls on DAPI is an effective means of managing risks associated with this substance. It is considered that it is not necessary to apply environmental user charges to this substance as an alternative or additional means of achieving effective risk management. Accordingly, no report has been made to the Minister for the Environment. 8. Conclusion 8.1. Taking into account the staff’s assessment of the potential risks, costs and benefits associated with DAPI (see Section 5), I consider that, with controls in place: the risks to human health and the environment arising from the hazardous properties (see Table 1, Section 4) of DAPI are negligible; significant adverse impacts on the social or economic environment with DAPI are not anticipated; it is unlikely that DAPI could have a significant impact on Māori culture or traditional relationships with ancestral lands, water, sites, wāhi tapu, valued flora and fauna or other taonga or will breach the principles of the Te Tiriti o Waitangi/Treaty of Waitangi; and benefits will be derived for New Zealand by allowing the use of DAPI. www.epa.govt.nz Page 9 of 18 Application for approval to import DAPI for release (APP201371) 9. Decision 9.1. Pursuant to section 29 of the Act, I have considered this application to import a hazardous substance for release made under section 28 of the Act and have applied the relevant sections of the Act and clauses of the Hazardous Substances and New Organisms (Methodology) Order 1998 (“the Methodology”) as detailed in the decision path and explanatory notes available from our website3. 9.2. I am satisfied with the hazard classifications identified by the staff in Table 1 (Section 4) and accordingly confer them on DAPI. 9.3. I consider that, with controls in place, the risks to human health and to the environment are negligible, and there will be benefits associated with the release of DAPI. Therefore, I consider that the application may be approved in accordance with clause 26, with the controls proposed by the staff and documented in Appendix C. 9.4. The import the hazardous substance, DAPI, is thus approved with controls as listed in Appendix C.
