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 ...
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.
[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.
The Central Pollution Control Board (CPCB) reported that as of 2016, there were 746 industries directly depositing wastewater into the Ganga, which is the largest river in India. This wastewater contains heavy metals such as lead , cadmium , copper , chromium , zinc , and arsenic , which negatively affect both aquatic life as well as human health.
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 ...
2 emissions are measured in pounds per hour using both an SO 2 pollutant concentration monitor and a volumetric flow monitor. For NO x, both a NO x pollutant concentration monitor and a diluent gas monitor are used to determine the emissions rate in weight per volume or weight per heat value (for example lbs/million Btu, lbs/ft 3, kg/kWh or kg ...
In addition to wastewater discharge monitoring, EPA works with federal, state and local environmental agencies to conduct ambient water monitoring programs in water bodies nationwide. [23] The CWA requires EPA and the states to prepare reports to Congress on the condition of the nation's waters. [24]
The secondary treatment standards for POTWs and the effluent guidelines are implemented through NPDES permits. (See Title IV .) The categorical pretreatment standards are typically implemented by POTWs through permits that they issue to their industrial users.
