Reassessment of methyl bromide

Stakeholders in Methyl Bromide Reduction Inc (STIMBR) have applied for a reassessment of methyl bromide.

The application, formally received on 9 April 2019, is to amend the controls on the use of methyl bromide, particularly the control that required that operators recapture methyl bromide from October 2020.

A remote hearing for this application was held from 11 to 17 August 2020. It was adjourned so that the Decision-making Committee (DMC) could deliberate their decision, based on the information presented before and during the hearing.

Latest update – 6 April 2021

In Direction and Minute WGT031 on 8 March 2021, the DMC directed the EPA to provide a summary of the modelling that had been received since the hearing were adjourned, and how that modelling relates to any potential buffer zones.

The EPA’s Update Report provides this information to support the DMC in its deliberations. The Update Report also provides an indication of the hazard classification when the impending changes to New Zealand’s classification system goes live later this month.
