What is the Oil and Gas Extraction Industry?
Oil and Gas Extraction is the exploration and production of petroleum and natural gas from wells. The industry generates wastewater from the water extracted from the geological formations and from chemicals used during exploration, well drilling and production of oil and gas.
These activities are included within NAICS code 211111, Crude Petroleum and Natural Gas Extraction. (Note: the NAICS group listings are provided as a guide and do not define the coverage of the O&G regulations. For precise definitions of coverage, see the applicability sections in 40 CFR Part 435.)

Subpart C Amendments: Unconventional Extraction
EPA has issued a proposed rule (April 7, 2015) to address wastewater pollutant discharges from onshore unconventional oil and gas extraction facilities to municipal wastewater treatment plants.
Coalbed Methane Extraction
EPA has not promulgated effluent limitations guidelines and standards for pollutant discharges from coalbed methane extraction facilities. EPA had initiated a coalbed methane rulemaking, but announced its decision to discontinue this effort in Fall 2014.
