2016-02306: National Emission Standards for Hazardous Air Pollutant Emissions: Petroleum Refinery Sector Amendments

Summary

This action proposes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) Refinery MACT 1 and Refinery MACT 2 regulations and the New Source Performance Standards (NSPS) for petroleum refineries, which were published on December 1, 2015. In that action, as a result of a risk and technology review, the Environmental Protection Agency (EPA) finalized amendments to Refinery MACT 1 and Refinery MACT 2. In this action, the EPA is proposing to amend the compliance date in Refinery MACT 1 for maintenance vent standards that apply during periods of startup, shutdown, maintenance or inspection for sources constructed or reconstructed on or before June 30, 2014. In this action, the EPA is also proposing to revise the compliance dates in Refinery MACT 2 for the standards that apply during startup, shutdown, or hot standby for fluid catalytic cracking units (FCCU) and startup and shutdown for sulfur recovery units (SRU) constructed or reconstructed on or before June 30, 2014. These proposed revisions do not affect requirements that apply during normal operations. Finally, the EPA is proposing technical corrections and clarifications to the NESHAP and the NSPS for petroleum refineries. This action will have an insignificant effect on emissions reductions and costs.
