EPA has published many methods in its regulations, [4] and has approved the use of other methods published by peer-reviewed sources, such as Standard Methods. [5] Although the effluent limitations are based on the performance of control and treatment technologies (and not the impacts to receiving waters), the regulations do not require ...
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.
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.
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.
To implement TMDLs with point sources, wasteload allocations are incorporated into discharge permits for these sources. [13] The permits are issued by EPA or delegated state agencies under the National Pollutant Discharge Elimination System . Nonpoint source discharges (e.g. agriculture) are generally in a voluntary compliance scenario.
[1] [2] These sources include all industries, businesses, municipal sewage treatment plants and storm sewer systems, and other facilities that discharge to surface waters. Effluent limitations are implemented in discharge permits issued by the Environmental Protection Agency (EPA) and state agencies, through the National Pollutant Discharge ...
Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...
Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". [ 1 ]
