On June 24, 2008, EPA published in the Federal Register final amendments to the current standards of performance for petroleum refineries and separate standards of performance for new, modified, or reconstructed process units at petroleum refineries. Both of these final rules had an effective date of June 24, 2008. This document stays the effective date of the rule for the newly promulgated standards of performance for new, modified, or reconstructed process units at petroleum refineries to September 26, 2008 to be consistent with sections 801 and 808 of the Congressional Review Act, enacted as part of the Small Business Regulatory Enforcement Fairness Act, 5 U.S.C. 801, 808. The effective date for the final rule promulgating amendments to the current standards of performance for petroleum refineries is not changing and remains June 24, 2008.
