EPA has issued a final rule allocating for critical uses in 2011 more than 2 million kilograms of methyl bromide, a substance regulated under the Montreal Protocol on Substances that Deplete the Ozone Layer. 76 Fed. Reg. 60,736 (9/30/11). The 2011 allocation represents 8.1 percent of the baseline amount of methyl bromide used in the United States in 1991. Under the Montreal Protocol, regulated substances are phased out but critical use exemptions are allowed for industries, such as agriculture, where it is used as a pesticide on crops, and pork processing, that do not have technologically and economically feasible alternatives. The final rule also modifies the list of critical uses and removes certain growers from eligibility for critical use. The rule is effective immediately.
