Abstract: Methyl Bromide (MeBr), a widely used pesticide in agriculture, is regulated for its potential ozone-depleting effects in the Earth’s stratosphere. Controls on production, emissions, and trade are mandated internationally under the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer (the “Protocol”) and domestically under Title VI of the U.S. Clean Air Act (CAA). Production for nonessential uses was banned December 31, 2004, but the Protocol still regulates post-2004 production for critical uses. U.S. agribusinesses have sought Critical Use Exemptions from the Environmental Protection Agency (EPA) to treat commodities with MeBr after the ban. Exemptions are resisted by some Protocol parties and environmental advocates who seek a rapid, definitive ban on production and use. Chemical companies maintain they cannot foresee development of effective chemical substitutes for all uses of MeBr in the near term, and agricultural producers indicate they may have to rely on less economical and less effective treatments. Production allowances for MeBr for 2005-2007 were approved under the Protocol and the EPA has approved allocation for registered users. Its production in decline, the EPA has stated it may permit commercial trade of pre-2005 manufactured MeBr. This report is updated as warranted.
