The U.S. Environmental Protection Agency (USEPA) is delaying the effective dates for final rules regulating Industrial, Commercial, and Institutional Boilers and Process Heaters, and for Commercial/Industrial Solid Waste Incinerators. We discussed these rules, known as the Boiler MACT rules, in more detail when they were published on March 21. As we noted, USEPA was likely to reconsider the Boiler MACT rules, and additional changes were expected. On May 16, USEPA issued a notice that they were delaying the compliance dates for the Boiler MACT rules until either the proceedings for judicial review of the regulations is complete, or until the Agency completes its reconsideration of the rules. The purpose of the delay is straightforward: to allow USEPA to seek additional public comment before requiring thousands of facilities to make significant capital investments that may not be reversible if the standards are revised following reconsideration.
