BUFFER ZONES
SLIDE 9
Buffer zones
Use Minimum Buffer Zone (m) Ship’s hold (greater than 1000 kg methyl bromide used) 100 Ship’s hold (less than 1000 kg) 50 Logs/timber under covers outdoors and indoors (without recapture technology) 50 More than 1 shipping container (77 m3) per hour 25 1 shipping container (77 m3) per hour 10

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
SLIDE 12
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
SLIDE 14
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
