EPA Proposes Amendments to Two Air Toxics Standards to Remove Affirmative Defense Provisions
Nov. 21, 2023 - EPA has proposed amendments to two air toxics standards that apply to oil and natural gas operations: the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for oil and natural gas production facilities and the NESHAP for natural gas transmission and storage facilities. The proposed amendments would remove affirmative defense provisions from the rules to make them consistent with 2014 decision from the U.S. Court of Appeals for the D.C. Circuit. Members of the public have until December 6, 2023 to request a public hearing on the proposal. EPA will accept written comments on the proposal through January 16, 2024.
