Effluent Guidelines are national regulatory standards for wastewater discharged to surface waters and municipal sewage treatment plants. EPA issues these regulations for industrial categories, based on the performance of treatment and control technologies.
Effluent Guidelines are national standards for industrial wastewater discharges to surface waters and publicly owned treatment works (municipal sewage treatment plants). The EPA issues Effluent Guidelines for categories of existing sources and new sources under Title III of the Clean Water Act.
Indirect dischargers: 40 CFR 403.3 (e) CWA section 304 (e) authorizes the EPA to include BMPs in Effluent Guidelines for certain toxic or hazardous pollutants for the purpose of controlling "plant site runoff, spillage or leaks, sludge or waste disposal, and drainage from raw material storage."

NPDES permits establish discharge limits and conditions for discharges from municipal wastewater treatment facilities to waters of the United States. Resources for discharge requirements include: Primer for Municipal Wastewater Treatment Systems (pdf) (4.19 MB) - Overview of municipal processes used to treat domestic wastewater before discharge ...
Effluent Guidelines are national wastewater discharge standards that are developed by EPA on an industry-by-industry basis. These are technology-based regulations, and are intended to represent the greatest pollutant reductions that are economically achievable for an industry.
Effluent limitations serve as the primary mechanism in NPDES permits for controlling discharges of pollutants to receiving waters. When developing effluent limitations for an NPDES permit, a permit writer must consider limits based on both the technology available to control the pollutants (i.e., technology-based effluent limits) and limits ...
These regulations apply to about 40,000 facilities that discharge directly to the nation's waters, 129,000 facilities that discharge to municipal sewage treatment plants, and certain construction sites.
Chapter 6 Water Quality-Based Effluent Limits. In general, there are two stages of mixing: discharge-induced and ambient induced. The first stage is controlled by discharge jet momentum and buoyancy of the effluent. This stage generally covers most of the mixing zone allowed by State water quality standards.
The EPA promulgated the Oil and Gas Extraction Effluent Guidelines and Standards (40 CFR Part 435) in 1979, and amended the regulations in 1993, 1996, 2001 and 2016. The regulations cover wastewater discharges from field exploration, drilling, production, well treatment and well completion activities.
