National Emission Standards for Hazardous Air Pollutants: Asphalt Processing and Asphalt Roofing Manufacturing. Background Information Document for Promulgated Standards

摘要

On November 21, 2001, the Environmental Protection Agency (EPA) proposed regulations (40 CFR part 63, subpart LLLLL) in the Federal Register (66 FR 58610) to establish National Emission Standards for Hazardous Air Pollutants (NESHAP) for new and existing asphalt processing and asphalt roofing manufacturing facilities. Also, on June 12, 2002, EPA distributed a letter commenters with asphalt processing facilities to clarify that the proposed NESHAP would apply to all asphalt processing operations regardless asphalt's end use. This letter invited comment on this clarification of rule applicability. This document contains summaries of the public comments that EPA received on the proposed standards and subsequent applicability clarification and EPA's responses to those comments. This summary of comments and responses serves as a basis for revisions made to the NESHAP between proposal and promulgation.
