Finding of Failure to Submit State Implementation Plans for the 2015 Ozone National Ambient Air Quality Standard (NAAQS)
On December 10, 2021 the U.S. Environmental Protection Agency (EPA) found that two states failed to submit timely state implementation plan (SIP) revisions necessary to satisfy certain Clean Air Act and EPA requirements for implementing the 2015 ozone NAAQS. Specifically, this action finds that New York and Pennsylvania have not provided required (SIP) revisions to EPA for the 2016 Oil and Natural Gas Industry Control Techniques Guidelines (CTG) for the 2015 ozone NAAQS. The findings establish a 24-month deadline for EPA to either approve SIPs or finalize Federal Implementation Plans addressing sources in these states covered by the CTG. The findings also establish timelines for the implementation of two mandatory sanctions that will take effect if New York and Pennsylvania do not submit complete SIPs to address the CTG, as required by the Clean Air Act.
