ENV-16-85 Lessons Learned from Fenceline Monitoring Trial Programs

Description:

On December 1, 2015, the U.S. Environmental Protection Agency (USEPA) promulgated the final rule entitled Petroleum Refinery Sector Risk and Technology Review and New Source Performance Standards. This rule was the result of USEPA’s mandated review of the existing Maximum Achievable Control Technology (MACT) standards for petroleum refineries under the National Emission Standards for Hazardous Air Pollutants (NESHAP). Two reviews were required, collectively known as the Risk and Technology Review (RTR). The first was a Residual Risk Assessment to determine if additional emission reductions are warranted to protect public health or the environment; the second review was a Technology Review to determine if better emission control approaches, practices, or processes are available. The RTR encompassed two existing emission standards for refineries, namely, Refinery MACT 1 (40 Code of Federal Regulations [CFR] 63, Subpart CC) and Refinery MACT 2 (40 CFR 63, Subpart UUU). In addition to revisions to the two MACT standards, the final rulemaking, termed the Refinery Sector Rule (RSR), includes technical corrections to the New Source Performance Standard (40 CFR 60, Subpart Ja) for refineries. The USEPA stated that there are currently 142 large (major source) and 7 small (area source) petroleum refineries in the U.S. that will be affected by the rule.
