The EPA published in the Federal Register the "Release of Final Control Techniques Guidelines for the Oil and Natural Gas Industry" on October 27, 2016 (81 FR 74798). These guidelines provide recommendations for reducing volatile organic compound emissions from existing oil and natural gas equipment and processes in moderate and higher classified ozone nonattainment areas and states in the Ozone Transport Region. On March 9, 2018, EPA proposed to withdraw the CTG in its entirety (83 FR 10478). The EPA is no longer pursuing this action to withdraw the CTG, and the CTG will remain in place as published on October 27, 2016 (81 FR 74798).
