Study of Oil and Gas Extraction Wastewater Management
Study of Oil and Gas Extraction Wastewater Management Under the Clean Water Act EPA‐ 821‐R19‐001 U.S. Environmental Protection Agency Engineering and Analysis Division Office of Water 1200 Pennsylvania Avenue, NW Washington, D.C. 20460 Draft May 2025
EPA established pretreatment standards for the Oil and Gas Extraction Category (40 CFR Part 435) under the Onshore Subcategory (Subpart C) in 2016.The standards prohibit discharges of wastewater pollutants from onshore unconventional oil and gas (UOG) extraction facilities to publicly owned treatment works publicly owned treatment worksA treatment works that is owned by the state or municipality.
EPA bans disposal of fracking waste water at public
Courtesy of Clean Water Action. Waste Treatment Corporation in Warren, Pa. The EPA has banned oil and gas producers from using publicly owned treatment facilities to dispose of fracking waste.
In 2016, the EPA went further, and prohibited companies who operate “unconventional wells” from disposing of their wastewater into municipal treatment systems, known as Publicly Owned Treatment Works (POTW), since these city-owned facilities are not designed to handle this type of industrial waste.
Wastewater Treatment Tank Systems - US EPA
• Wastewater treatment tank systems that are part of a wastewater treatment facility regulated under section 402 or 307(b) of the Clean Water Act (CWA) are excluded from the UST regulation. 4 This means none of the UST regulatory requirements apply. • All other wastewater treatment tank systems are deferred from most of the UST
Oil and Gas Stormwater Regulatory Background. The 1987 Water Quality Act (WQA) added § 402(l)(2) to the CWA. This new section forbade EPA and the states from requiring NPDES permits for uncontaminated stormwater discharges from oil and gas exploration, production, processing or treatment operations, or transmission facilities:

Clean Water Act. Wastewater Management. Under the CWA's National Pollutant Discharge Elimination System (NPDES) program, EPA regulates discharges of pollutants from municipal and industrial wastewater treatment plants, sewer collection systems, and stormwater discharges from industrial facilities and municipalities.
Detailed information is available in EPA’s report at EPA 821-R-09-008. Oil & gas guidelines. This rule is intended to prevent the discharge of wastewater from onshore oil and gas production facilities to publicly owned treatment works (POTWs) and is directly aimed at oil- and gas-producing wells and hydraulic fracturing processes.
EPA Aims At Water Resources, Could Hit Oil & Gas
The other area Wheeler mentioned, according to AP, is wastewater treatment and recycling for oil and gas operations. That opens up a whole new can of worms for oil and gas stakeholders.
The culprit: wastewater from oil and gas drilling and coal mines. This included fracking wastewater that state officials had allowed to be dumped at local sewer plants—facilities incapable of removing the complex mix of chemicals, corrosive salts and radioactive materials from that kind of industrial waste before they piped the "treated" water back into Pennsylvania's rivers.
EPA’s waste water treatment rule splits environmentalists
The U.S. EPA’s plan to prevent municipal water treatment plants from accepting fracking waste is being hailed by supporters as a necessary safeguard against the contamination of public water
Headworks 'head of the works' or 'inlet works' of a sewage wastewater treatment plant, would generally incorporate a system of screens, filters, detritors and classifiers that effectively remove solids, grit and other debris from the influent wastewater. Regardless of industry, raw water must be treated before it can be used downstream.
- What is polyacrylamide used for?
- Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.
