A simple Google search of "EPA III Enforcement" and a click on the "Natural Gas Extraction/Marcellus Shale" link at the EPA Region III website should cause any company concern. The site lists 27 administrative orders issued for alleged violations of Section 404 of the Clean Water Act (all in West Virginia), 16 Section 308 requests to natural gas drillers and publicly owned treatment works that were accepting "oil and gas wastewater", 13 additional administrative orders and information requests under § 309 of the CWA to facilities accepting wastewater from Marcellus Shale drilling operations, and extensive effluent sampling data provided by POTWs as a result of EPA's information requests. Outside EPA Region III, the United States Department of Justice recently announced a major settlement with a midstream natural gas company requiring payment of a $4 million penalty, removal of certain equipment and installation of additional pollution control devices related to alleged violations of the Clean Air Act ("CAA").
