To amend the Clean Air Act to modify certain provisions regarding methyl bromide, and for other purposes.

Amends the Clean Air Act to authorize the production of methyl bromide in the same amount requested by the United States under the critical use exemption process of the Montreal Protocol, even if the parties to the protocol do not approve the entire amount. (Methyl bromide is a fumigant used to control insects, nematodes, weeds, and pathogens that has been defined under the Montreal Protocol of 1991 as a chemical that contributes to depletion of the ozone layer. The Montreal Protocol requires a phase out in production in the United States on a more accelerated schedule than that required of developing countries with which U.S. agriculture competes.)
