New Zealand is proposing to amend Schedule 2A of the Hazardous Substances and New Organisms Act (HSNO Act) to include three new chemicals: Methoxychlor, Dechlorane Plus, and UV-328. These chemicals were added to Annex A of the Stockholm Convention on Persistent Organic Pollutants (POPs) in May 2023 and must be restricted in New Zealand to comply with international obligations. A public consultation on these proposed amendments is now open and submissions are invited until 4 September 2024.
Background
The Stockholm Convention aims to eliminate or restrict the production and use of POPs, which are highly toxic chemicals that persist in the environment and human bodies, bioaccumulate in the food chain and are transported over long distances. New Zealand implements the Stockholm Convention through the HSNO Act, which lists POPs and any specific exemptions in Schedule 2A.
Proposal: Chemicals to be Restricted
Below are details of the three substances and their proposed restriction, as well as the consultation questions for each substance.
Methoxychlor
Uses: Historically used as an agricultural, veterinary, and domestic insecticide.
Status in New Zealand: No current approvals or registered products. Not listed in the New Zealand Inventory of Chemicals (NZIoC).
Specific Exemptions: None.
Consultation Questions
Do you agree with the proposal to include methoxychlor in Schedule 2A of the HSNO Act?
Do you have information on the use, stockpiles, contamination, imports or exports of methoxychlor in New Zealand?
Dechlorane Plus
Uses: Flame retardant in adhesives, sealants and polymers. Mainly used in motor vehicles, aerospace, defence, electronics and medical devices.
Status in New Zealand: Listed in the NZIoC but no specific approvals under the HSNO Act.
Specific Exemptions: Aerospace, space and defence applications, medical imaging and radiotherapy devices, and replacement parts for specific applications until end of life or 2044.
Consultation Questions
Do you agree with the proposal to include Dechlorane Plus in Schedule 2A of the HSNO Act?
Do you have information on the current use, products, imports, exports, stockpiles, waste, or contaminated sites of Dechlorane Plus in New Zealand?
Should New Zealand register for specific exemptions for Dechlorane Plus? Which applications should be considered for exemptions?
Do you have information on articles in use that contain Dechlorane Plus?
UV-328
Uses: UV absorber in automotive paints, coatings, adhesives, plastics, rubbers and various other materials.
Status in New Zealand: Listed in the NZIoC but no specific approvals under the HSNO Act.
Specific Exemptions: Motor vehicle parts, industrial coating applications, mechanical separators in blood collection tubes, TAC film in polarizers, photographic paper and replacement parts for specific applications until end of life or 2044.
Consultation Questions
Do you agree with the proposal to include UV-328 in Schedule 2A of the HSNO Act?
Do you have information on the current use, products, imports, exports, stockpiles, waste or contaminated sites of UV-328 in New Zealand?
Should New Zealand register for specific exemptions for UV-328? Which applications should be considered for exemptions?
Do you have information on articles in use that contain UV-328?
Imports and Exports (Restrictions) Prohibitions Order (No 2) 2004
In order to align with the Stockholm Convention, methoxychlor, Dechlorane Plus and UV-328 need to be included in Schedule 1 of the Imports and Exports (Restrictions) Prohibition Order (No 2) 2004 to regulate their export and ensure compliance with international obligations.
Consultation Questions:
Do you agree with the proposal to include Methoxychlor, Dechlorane Plus, and UV-328 in Schedule 1 of the Imports and Exports (Restrictions) Prohibition Order (No 2) 2004?
Do you have any general comments regarding the inclusion of these chemicals in Schedule 1 of the Imports and Exports (Restrictions) Prohibition Order (No 2) 2004?
Best International Practices, Costs, and Benefits
Including these chemicals in Schedule 2A of the HSNO Act will bring New Zealand into line with international best practices, reduce exposure to these toxic chemicals, ensure compliance with international obligations, and support New Zealand's primary exports. The costs are considered low due to the global phase-out production and use of these chemicals and the availability of alternatives.
Next Steps
The public is invited to comment on the proposals by 5 pm on Wednesday 4 September 2024. The Environmental Protection Authority (EPA) will review the submissions, prepare a report and seek Cabinet approval to amend Schedule 2A of the HSNO Act. The amendments are intended to come into force on 26 February 2025.
