EPA to consider EDN, a methyl bromide alternative
Draslovka, a Czech-based firm, has applied for approval to import ethanedinitrile (EDN) into New Zealand as an alternative to the fumigant methyl bromide which is used for export logs and timber at New Zealand ports.
EDN has been identified as a possible substitute following an international review of alternative treatments.
In 2018, 22 percent of all exported logs were treated with methyl bromide. According to the Ministry for Primary Industries, fumigation of logs and timber exports accounts for 92 percent of methyl bromide use in New Zealand.
An EPA Decision-making Committee is considering the EDN application.
The timeline for this application process has been extended to enable additional information to be considered. You can see what's happened so far, and related documents for this application, on the timeline.
On 23 August 2021, we released an updated staff report and updated science memorandum prepared by the EPA in light of the Decision-making Committee’s (DMC) Direction and Minute 11.
These documents have been provided as advice to the DMC considering the EDN application, and address:
- changing previous HSNO hazard classifications to GHS hazard classifications
- developments since the first staff report, including those during the hearing adjournment
- draft Safe Work Instrument(s) developed by WorkSafe that have been agreed in principle.
The updated staff report should be read alongside the 2018 staff report and the 2019 addendum. The updated science memo should be read alongside the 2018 science memorandum.
On 31 August 2021, the Decision-making Committee (DMC) released Direction and Minute 12 in response to the release of the updated EPA Staff Report 2021 and updated EPA Science Memorandum 2021.
