Proposed Rulemaking: Guidelines for Best Available Retrofit Technology (BART) Determinations Under the Regional Haze Rule and Amendments to the Regional Haze Rule (Signed April 15, 2004, Published May 5, 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.

Results of the Integrated Planning Model (IPM) for the Revisions to the Regional Haze Regulations and Guidelines for BART Determinations

Note: Due to data availability considerations, this IPM run was based on the application of BART-level controls to BART eligible EGUs larger than 250 MW. However, under the proposed BART rule, States are also required to make BART determinations for BART eligible EGUs smaller than 250 MW. Therefore we anticipate that emission reductions will be somewhat greater than predicted here. We intend to do further analysis of the effect of applying BART to these smaller EGUs.
