Environmental Protection Agency February 6, 2007 – Federal Register Recent Federal Regulation Documents

On September 15, 1997, EPA adopted new source performance standards (NSPS) and emission guidelines for hospital/medical/ infectious waste incinerators (HMIWI). The NSPS and emission guidelines were established under sections 111 and 129 of the Clean Air Act (CAA). On November 14, 1997, the Sierra Club and the Natural Resources Defense Council (Sierra Club) filed suit in the U.S. Court of Appeals for the District of Columbia Circuit (the Court) challenging EPA's methodology for adopting the regulations. On March 2, 1999, the Court issued its opinion. The Court remanded the rule to EPA for further explanation of the Agency's reasoning in determining the minimum regulatory ``floors'' for new and existing HMIWI. The Court did not vacate the regulations, so the NSPS and emission guidelines remained in effect during the remand and were fully implemented by September 2002. This action provides EPA's proposed response to the questions raised in the Court's remand. Section 129(a)(5) of the CAA requires EPA to review and, if appropriate, revise the NSPS and emission guidelines every 5 years. In this action, EPA also is proposing our response to this 5-year review, which would revise the emission limits in the NSPS and emission guidelines to reflect the levels of performance actually achieved by the emission controls installed to meet the emission limits set forth in the September 15, 1997, NSPS and emission guidelines.
