National Emission Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers and Process Heaters: Reconsideration

概要

EPA is promulgating amendments to the national emission standards for hazardous air pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters which EPA promulgated on September 13, 2004. After promulgation of the final rule for boilers and process heaters, the Administrator received petitions for reconsideration of certain provisions in the final rule. On July 27, 2005, EPA published a notice of reconsideration and requested public comment on certain aspects of the health-based compliance alternatives, as outlined in 40 CFR 63.7507 and appendix A to the final rule (40 CFR part 63, subpart DDDDD). After evaluating public comment on the notice of reconsideration, we are retaining the health-based compliance alternatives in the final rule in substantially the same form. However, we are making a limited number of amendments to 40 CFR 63.7507 and appendix A to the final rule to improve and clarify the process for demonstrating eligibility to comply with the health-based compliance alternatives contained in the final rule.
