Effluent limits – limits used to control discharges through technology-based or water quality-based standards; Monitoring and reporting requirements – used to determine permit compliance; Special conditions – can be used to supplement effluent limits; Standard conditions – pre-established conditions that apply to all NPDES permits.
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 ...
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.
[2] Since the mid-1970s, EPA has promulgated ELGs for 59 industrial categories, with over 450 subcategories. Effluent Guidelines currently control pollution at approximately 40,000 facilities that discharge directly to the nation's waters, 129,000 facilities that discharge to POTWs, and construction sites.
Exceeding a numeric limitation constitutes a violation of the permit, and the discharger is subject to fines as laid out in section 309. Facilities must periodically monitor their effluent (i.e., collect and analyze wastewater samples), and submit Discharge Monitoring Reports to the appropriate
Functions of CPCB comes under both national level and as State Boards for the Union Territories. CPCB, under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, aims to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and to improve the quality ...
Continuous emission monitoring systems (CEMS) are used as a tool to monitor the effluent gas streams resulting from combustion in industrial processes. CEMS can measure flue gas for oxygen , carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings.
Effluent guidelines (technology based standards) for industrial point sources [144] and Water quality standards (risk-based standards) for water bodies, [145] under Title III of the CWA; Nonpoint source pollution programs [146] The CWA Section 404 Program regulates the discharge of dredged or fill material into waters of the United States.
