Proposed Rulemaking: Guidelines for Best Available Retrofit Technology (BART) Determinations Under the Regional Haze Rule and Amendments to the Regional Haze Rule
April 15, 2004 - The Environmental Protection Agency (EPA) is proposing to amend its regional haze rule to provide guidelines for state and tribal air quality agencies to use in determining how to set air pollution limits for a number of older, large utilities and other industrial plants, to address visibility impairment in scenic areas. In May 2002, the DC Circuit court vacated certain provisions of the regional haze rule related best available retrofit technology (BART). Because of this remand, we need to repropose guidelines intended to add further clarification to the BART requirements in the regional haze rule. The purpose of this rulemaking is to provide the appropriate changes to the BART requirements and guidelines.
