On July 6, 2020, the U.S. Environmental Protection Agency (EPA) finalized the residual risk and technology review (RTR) conducted for the Ethylene Production source category, which is part of the Generic Maximum Achievable Control Technology (GMACT) Standards National Emission Standards for Hazardous Air Pollutants (NESHAP); on July 7, 2020, the EPA finalized the RTR conducted for the Organic Liquids Distribution (Non-Gasoline) NESHAP; and on August 12, 2020, the EPA finalized the RTR conducted for the Miscellaneous Organic Chemical Manufacturing NESHAP. Amendments to the Petroleum Refineries NESHAP were most recently finalized on February 4, 2020. Subsequently, the EPA received and granted various petitions for reconsideration on these NESHAP for, among other things, the provisions related to the work practice standards for pressure relief devices (PRDs), emergency flaring, and degassing of floating roof storage vessels. In response to the petitions, the EPA is proposing amendments to the work practice standards for PRDs, emergency flaring, and degassing of floating roof storage vessels. In addition, the EPA is proposing other technical corrections and clarifications for each of the rules. The EPA will not respond to comments addressing any other issues or any other provisions of the final rule not specifically addressed in this proposed rulemaking.
