Ground-level Ozone Pollution

Findings of Failure to Submit State Implementation Plan Revisions in Response to the 2016 Oil and Natural Gas Industry Control Techniques Guidelines for the 2008 Ozone National Ambient Air Quality Standards and for States in the Ozone Transport Region

EPA is finding that California, Connecticut, New York, Pennsylvania, and Texas failed meet the Clean Air Act deadline to submit complete State Implementation Plan (SIP) revisions that satisfy the Oil and Natural Gas Industry Control Techniques Guidelines (CTG) reasonably available control technology requirement for the 2008 ozone National Ambient Air Quality Standard (NAAQS).  The required SIP revisions were due on October 27, 2018 and apply to certain nonattainment areas and the states in the ozone transport Region (OTR). EPA is committed to working with California, Connecticut, New York, Pennsylvania, and Texas to expedite the development and submission of their state plan revisions and to ensure continued progress toward cleaner air.
