National Emission Standards for Hazardous Air Pollutant Emissions: Petroleum Refinery Sector

On December 1, 2015, the Environmental Protection Agency (EPA) finalized amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) Refinery Maximum Achievable Control Technology (MACT) 1 and Refinery MACT 2 regulations and the New Source Performance Standards (NSPS) for petroleum refineries. Subsequently, the EPA received three petitions for reconsideration of the final rules. The EPA is announcing reconsideration and request for public comment on five issues raised in the petitions for reconsideration where petitioners claim that the public was not afforded an opportunity to comment. Additionally, the EPA is proposing amendments to the final rule to clarify a compliance issue raised by stakeholders subject to the final rule and to correct a referencing error. The EPA is seeking comment only on the five identified petition issues and on the proposed compliance issue clarification and referencing error amendments. The EPA will not respond to comments addressing any other issues or any other provisions of the final rule.
