Key issues – International – EU Ban – The Montreal Protocol – Alternatives – Horticulture – Commodities – Logs – Health effects – Motor neurone disease

Key issues – International – EU Ban – The Montreal Protocol – Alternatives – Horticulture – Commodities – Logs – Health effects – Motor neurone disease

Controls – TELs (Tolerable Exposure Limits) – Buffer zones – Monitoring – Recapture

BUFFER ZONES

Buffer zones Use Minimum Buffer Zone (m) Ship’s hold (greater than 1000 kg methyl bromide 100 used) Ship’s hold (less than 1000 kg) 50 Logs/timber under covers outdoors and indoors 50 (without recapture technology) More than 1 shipping container (77 m 3 ) per hour 25 1 shipping container (77 m 3 ) per hour 10

Controls – Monitoring – Recapture

Controls – Recapture – Practical? – Affordable?

Risk-based approach Weighing the risks, costs, & benefits: – Human health and safety – Environment – Relationship of Māori to the environment – Society and communities – Market economy – International obligations

Risk-based approach – Human health and safety – Exposure is involuntary – Risk will persist over time – Potential adverse effects are irreversible – Risk not understood by public – Little experience or understanding of possible measures for managing effects

Risk-based approach – Environment – Relationship of Māori to the environment – Society and communities – Market economy – International obligations

Methyl Bromide Key recommendations for additional controls: – Setting tolerable exposure limits – Minimum buffer zones – Requirements for air quality monitoring – Use of recapture technology for all shipping container fumigations – Requiring major fumigations to be notified – Restricted to use for quarantine and pre- shipment (QPS) purposes
