State-adopted and EPA-approved ambient standards for water bodies. The standards define the water quality goals of a water body by designating the uses of the water and setting criteria to protect those uses. The standards protect public health and welfare, enhance the quality of the water, and provide the baseline for surface water protection under the Clean Water Act.
Includes three major components: designated uses, water quality criteria, and antidegradation provisions.
A provision of State or Federal law consisting of a designated use or uses for a water body and the quantifiable criteria protective of the use(s). Standards may be annual or seasonal, depending on the designated use.
Standards for water quality established under Section 303 of the U.S. Clean Water Act. The water quality standards program is covered by an implementing regulation in 40 CFR 131. A water quality standard is a rule or law consisting of three elements: (1) the designated use (or uses) to be made of the water body or segment; (2) the water quality criteria needed to protect that use (or uses); and (3) an antidegradation policy. Standards are to protect the public health or welfare, improve water quality, and serve the purpose of the Clean Water Act. Criteria are usually established thresholds that when violated may result in harm to beneficial uses of water.
State-adopted and USEPA-approved ambient standards for water bodies. The standards cover the use of the water body and the water quality criteria which must be met to protect the designated use or uses (e.g., drinking, swimming, fishing).
fixed limits of certain chemical, physical, and biological parameters in a water body; water quality standards are established for various uses of water (e.g. drinking)
A set of enforceable requirements under the Clean Water Act that include classification of receiving waters in accordance with their federal or state designated use(s), use-based water quality criteria that establish measurable limits for specific pollutants, and antidegradation provisions to ensure that water quality is maintained or improved.
Standards established by the Connecticut Department of Environmental Protection for all of the State's waters to provide clear and objective statements for existing and projected water quality and the State's general program to improve Connecticut's water resources.
Established limits of certain chemical, physical, and biological parameters in a water body; water quality standards are established for the different designated uses of a water body.
A set of enforceablerequirements under the Clean Water Act thatinclude classification of receiving waters inaccordance with their federal or state designateduse(s), use-based water quality criteria that estab-lish measurable limits for specific pollutants, andantidegradation provisions to ensure that waterquality is maintained or improved.
Water quality standards are the foundation of the water quality-based control program mandated by the Clean Water Act. In Washington state, water quality standards are set by the Department of Ecology through a public process. A water quality standard consists of four basic elements: Designated uses of the water body (e.g., recreation, water supply, aquatic life, agriculture), water quality criteria to protect designated uses (numeric pollutant concentrations and narrative requirements), an antidegradation policy to maintain and protect existing uses and high quality waters, and general policies addressing implementation issues (e.g., low flows, variances, mixing zones).
Laws or regulations, promulgated under Section 303 of the Clean Water Act, that consist of the designated use or uses of a waterbody or a segment of a waterbody and the water quality criteria that are necessary to protect the use or uses of that particular waterbody. Water quality standards also contain an antidegradation statement. Every State is required to develop water quality criteria standards applicable to the various waterbodies within the State and revise them every 3 years.
State-adopted and EPA-approved ambient standards for waterbodies. The standards cover the use of the waterbody and the water quality criteria that must be met to protect the designated use or uses.
State-adopted and EPA-approved ambient standards for water bodies. The standards prescribe the use of the water body and establish the water quality criteria that must be met to protect designated uses.
