IDEM > Your Community > Workgroups > Regional Haze and Best Available Retrofit Technology (BART) Regional Haze and Best Available Retrofit Technology (BART)

On July 1, 1999, U.S. EPA published a final rule to address a visibility impairment known as regional haze (64 FR 35714). The regional haze rule requires states to submit state implementation plans (SIPs) to address regional haze visibility impairment in 156 Federally- protected parks and wilderness areas, referred to as Class I areas. Also included is a requirement for installation of best available retrofit technology (BART) at certain large stationary sources. BART is required for any source that is determined to emit air pollutants that may reasonably be anticipated to cause or contribute to visibility impairment in a Class I area. The BART guidelines were published on July 6, 2005 (70 FR 39104).

Although there are no Class I areas in Indiana, there are several in the region that may be affected by emissions from Indiana sources. The BART guidelines provide the mechanism for complying with the requirement to address visibility impairment in Class I areas. IDEM is obligated to submit the regional haze SIP by December 17, 2007, including a commitment that BART will be implemented in accordance with the federal guidelines.

Work Group Objectives

The Regional Haze and BART Work Group consists of representatives of companies, trade organizations, consulting firms, law firms, and environmentalists interested in the BART rulemaking and regional haze SIP effort. This group meets as needed for dissemination and discussion of information on the BART rulemaking and Regional Haze SIP effort.
