On March 23, 2000, the EPA issued national emission standards for hazardous air pollutants for secondary aluminum production under section 112 of the Clean Air Act (CAA). This action amends the standards to clarify compliance dates and defer certain early compliance obligations. These changes are being made as part of settlement agreements with industry trade associations, including the Aluminum Association and the American Foundrymen's Society. We are making these amendments by a direct final rule, without prior proposal, because we view these revisions as noncontroversial and anticipate no adverse comments. In addition, because we are publishing a separate proposal which includes substantive clarifications and revisions of the standard, we believe it will prevent confusion and disruption if we defer any compliance obligations until after that separate rulemaking can be completed.
