The U.S. Environmental Protection Agency (EP A) has issued air pollution standards for oil and gas production. The new standards revise new source performance standards (NSPS ) for volatile organic compounds (VOC s) from leaking components at onshore natural gas processing plants and for sulfur dioxide emissions from natural gas processing plants. They also establish standards for certain oil and gas operations not covered by existing standards. The standards will regulate VOC emissions from gas wells, centrifugal compressors, reciprocating compressors, pneumatic controllers, and storage vessels. The rule also sets National Emissions Standards for Hazardous Air Pollutants for the Oil and Natural Gas Production and Natural Gas Transmission and Storage source categories.  

EP A’s action resulted from a February 2010 consent decree approved by the U.S. District Court for the District of Columbia requiring the agency to issue NSPS and major source air toxic standards for the oil and gas industry. Wild Earth Guardians v. Jackson, No. 09-89 (D.D.C. 2/5/10). The new standards will be effective 60 days after they are published in the Federal Register.
