Best Available Retrofit Technology

EPA finalized the Best Available Retrofit Technology (BART) rule on June 15, 2005.  BART is part of the Regional Haze rule which aims to reduce visibility-impairing pollutants from sources nationwide to attain natural visibility in 156 Class I areas (national parks, etc) by 2064.  The projected result of these BART controls will be reduction of NOx emissions by 600,000 tons annually and SO2 emissions reduction of 400,000 tons annually.

Affected sources are those in one of 26 categories with the potential to emit more than 250 tons per year of a visibility-impairing pollutant (SO2, NOx, PM, may also include volatile organic compounds and ammonia) that were put into place between August 7, 1962 and August 7, 1977.  Sources include electric generating units (EGUs), cement plants, pulp mills, and iron and steel mills.  EPA believes that the BART rule will affect approximately 3,000 units (EGUs and non-EGUs).

States must submit their recommendations for sources that will be subject to BART by December 17, 2007.   EPA then has 18 months to approve the recommendation and once approved affected sources have 5 years to comply.  Therefore, the latest implementation of BART will be June 17, 2014.
