A Discharge Monitoring Report (DMR) is a United States regulatory term for a periodic water pollution report prepared by industries, municipalities and other facilities discharging to surface waters. [ 1 ] : 8–14 The facilities collect wastewater samples, conduct chemical and/or biological tests of the samples, and submit reports to a state ...
The permits (excluding most stormwater management permits) also specify procedures for collection of wastewater samples and the test methods that will be used to analyze the samples. [18]: 3–2 [18]: 8–11 Types of permits. Individual – A unique permit is issued for each discharger.
Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized engineered systems (e.g. filters, clarifiers, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance.
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 ...
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. For water bodies with stringent standards, such as Lake Tahoe , POTWs must treat their discharges to tertiary treatment levels, and then pump all treated water out of the drainage ...
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.
They can meet these objectives by surveillance and monitoring, and the Regional Water Boards have the authority to enforce these objectives. [2] Along with the Regional Water Boards, the State Water Resources Board can issue and enforce permits containing waste discharge requirements in order to maintain clean surface water and groundwater.
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 ...
