SCS Technical Bulletin: Summary of Refinery NSPS – NESHAP – MACT 1 – MACT 2 Technology Review, October 2015

The U.S. Environmental Protection Agency (EPA) issued a final rule on September 29, 2015, seeking to further control emissions of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from petroleum refineries. The rule imposes new requirements on storage vessels, delayed coker units and flares, and requires fenceline monitoring in addition to recordkeeping and reporting requirements summarized in the SCS Technical Bulletin below.

This action finalizes the residual risk and technology review conducted for the petroleum refinery source category regulated under the National Emission Standards for Hazardous Air Pollutants (NESHAP; 40 CFR Part 63, Subpart UUU), including the refinery Maximum Achievable Control Technology Standard (MACT) 1 and Refinery MACT 2.
