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 United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
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 ...

Wastewater analysis. All facilities in the United States that discharge wastewater to surface waters (e.g. rivers, lakes or coastal waters) must obtain a permit under the National Pollutant Discharge Elimination System, a Clean Water Act program administered by EPA and state agencies. The facilities covered include sewage treatment plants ...
Chart of Regulatory Analysis Processes under the Safe Drinking Water Act. To set a maximum contaminant level for a contaminant, EPA first determines how much of the contaminant may be present with no adverse health effects. This level is called the maximum contaminant level goal (MCLG). MCLGs are non-enforceable public health goals.
In the development of the effluent standards, the BAT concept is a "model" technology rather than a specific regulatory requirement. The U.S. Environmental Protection Agency (EPA) identifies a particular model technology for an industry, and then writes a regulatory performance standard based on the model. The performance standard is typically ...
