National Emission Standards for Hazardous Air Pollutants for Source Categories: General Provisions and Requirements for Control Technology Determinations for Major Sources in Accordance with Clean Air Act Sections, Sections 112(g) and 112(j), Background Information for Promulgated Standards.

摘要

The General Provisions, 40 CFR 63 subpart A, and the section 112(j) rule, 40 CFR 63 subpart B, are amended as the result of a litigation settlement agreement. The General Provisions establish general requirements that apply to each subpart under part 63, where indicated. The section 112(j) rule establishes the process for developing case-by-case maximum achievable control technology for major sources in source categories for which standards are not promulgated within 18 months after the date established under section 112(e). This document responds to comments received on the March 23, 2001 proposal of the amendments.
