The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for categories of industrial sources of water pollution under Title III of the Clean Water Act (CWA). [1] The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology ...
The basis for these limitations depends on the type of discharging facility, the discharge characteristics and status of the specific surface water body receiving the discharge. National technology-based standards apply to many industries (these standards are called "effluent guidelines"), [1]: 5-14–5-22 and to municipal sewage treatment plants.
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
EPA promotes "compliance assistance" as an enforcement technique, and has developed sector-specific assistance centers for various industries. [26] EPA and authorized state agencies perform periodic inspections of some discharging facilities. The states are responsible for enforcing the permit requirements that they have issued.
The Clean Water Act requires that state environmental agencies complete TMDLs for impaired waters and that the United States Environmental Protection Agency (EPA) review and approve / disapprove those TMDLs. [4] Because both state and federal governments are involved in completing TMDLs, the TMDL program is an example of cooperative federalism ...
The basic national standard for U.S. municipal treatment plants is the Secondary Treatment Regulation. [2] Most plants in the U.S. must meet this secondary treatment standard. The permit authority (state agency or EPA) can compel a POTW to meet a higher standard, if there are applicable water quality standards for the receiving water body.
The EPA standard for PFAS in drinking water is now 4 parts per trillion, down from 70 ppt. Health and environmental advocates have sought such a standard for decades in the face of stiff industry ...
The EPA regulations require each facility to apply for a specific permit for its wastewater discharges, and consequently require that each facility treat its wastewater. [101] In addition to effluent limitations , the permits include monitoring and reporting requirements, which are used by EPA and states to enforce the limitations. [ 17 ]
