Indirect dischargers are covered by the National Pretreatment Program, which enforces three types of discharge standards: prohibited discharge standards – protects against pollutants passing through the POTW untreated, and preventing interference with POTW treatment processes; categorical standards – national, technology-based standards for ...
Facilities that directly discharge to "waters of the United States" are required to obtain NPDES permits, and effluent guideline requirements are incorporated into these permits. Indirect dischargers (i.e. facilities discharging to POTWs) are subject to effluent guideline requirements called "Pretreatment Standards." [3] [12]

Nonpoint source (NPS) water pollution regulations are environmental regulations that restrict or limit water pollution from diffuse or nonpoint effluent sources such as polluted runoff from agricultural areas in a river catchments or wind-borne debris blowing out to sea.

[ 1 ] : 8–14 The facilities collect wastewater samples, conduct chemical and/or biological tests of the samples, and submit reports to a state ...
Point sources could include leaking septic tanks, oil spills, dumping of waste, or wastewater treatment facilities. [15] In order to prevent point source pollution from occurring, the Clean Water Act regulates what can be discharged into a water body by requiring each facility to obtain a National Pollutant Discharge Elimination System (NPDES ...
In the United States, the Clean Water Act requires all direct effluent discharges to surface waters to be regulated with permits under the National Pollutant Discharge Elimination System (NPDES). [ 15 ] [ 16 ] Indirect dischargers–facilities which send their wastewater to municipal sewage treatment plants–may be subject to pretreatment ...
Hawaii Wildlife Fund 590 U.S. __ (2020), a 6–3 ruling that a NPDES permit is required for point sources (as established in the statute) or for non-point sources that are "functionally equivalent" to direct discharge, such as in the specific case, wastewater discharged into injection wells that eventually reach the ocean, a navigable waterway.
Municipal and industrial permittees are required to regularly collect and analyze wastewater samples, and submit Discharge Monitoring Reports to a state agency or EPA. [17] Amendments in 1977 required stricter regulation of toxic pollutants. [18] In 1987 Congress expanded NPDES permit coverage to include municipal and industrial stormwater ...
