Water Pollution Control: Federal Act's Success Story

The Federal Water Pollution Control Act of 1948 was the first major U.S. law to address water pollution. However, it was not until the sweeping amendments in 1972, when it became known as the Clean Water Act (CWA), that it became successful in tackling water pollution. The CWA is the primary law governing pollution control and water quality in the nation's waterways. It regulates discharges of pollutants into U.S. waters and sets wastewater standards for industry and water quality criteria for all contaminants in surface waters. While the CWA has been successful in reducing water pollution, there are still challenges, such as emerging threats from climate change and the need to strengthen the Act to meet its original goals.

The 1972 amendments

The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. However, it was the sweeping amendments in 1972 that led to the law's modern form and its common name, the Clean Water Act (CWA).

The 1972 CWA also provided funding for the construction of sewage treatment plants under a construction grants program. Federal funds supported 75% of project costs, with state and local funds providing the remaining 25%. This program was later replaced by the Clean Water State Revolving Fund in the 1987 Water Quality Act (WQA).

The Clean Water Act is one of the United States' most influential modern environmental laws. Its laws and regulations are primarily administered by the EPA, in coordination with state governments. The Act regulates discharges of pollutants into US waters and controls pollution through various means, such as wastewater standards, national water quality criteria recommendations, and the NPDES permit program.

EPA's role

The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. The Environmental Protection Agency (EPA) was established in 1970, but initially had weak authority to protect US waters. The Clean Water Act (CWA) of 1972, which amended the 1948 Act, gave the EPA more authority to implement pollution control programs.

The CWA established the basic structure for regulating pollutant discharges into US waters and gave the EPA the power to implement pollution control programs, such as setting wastewater standards for industry. The EPA was also given the authority to develop national water quality criteria recommendations for surface waters. The CWA made it unlawful to discharge any pollutant from a point source into navigable waters without a permit, which is controlled by the EPA's National Pollutent Discharge Elimination System (NPDES) permit program.

The EPA also plays a role in ensuring that federal facilities and their contractors comply with CWA requirements. This includes adhering to any reporting, record-keeping, and permitting requirements. The EPA also works with the Department of Defense to establish Uniform National Discharge Standards for discharges incidental to the normal operation of a vessel of the Armed Forces.

The EPA has published various guidelines to regulate pollutant discharges, including effluent limitations guidelines and new source performance standards for NPDES permits. The EPA also established procedures, methods, and equipment requirements to prevent oil from reaching navigable waters and adjoining shorelines.

Discharge permits

The Clean Water Act (CWA) regulates the discharge of pollutants into US waters and controls pollution by means such as wastewater standards for industry, national water quality criteria recommendations for surface waters, and the National Pollutant Discharge Elimination System (NPDES) permit program. The CWA is the primary federal statute governing the restoration and maintenance of the "chemical, physical, and biological integrity of the Nation's waters".

The CWA establishes conditions and permitting for discharges of pollutants into the waters of the United States under the NPDES and gave the Environmental Protection Agency (EPA) the authority to implement pollution control programs such as setting wastewater standards for industry and water quality standards for all contaminants in surface waters. The EPA issues technology-based effluent guidelines that establish discharge standards based on treatment technologies that are available and economically achievable. Each EPA region issues permits that meet or exceed the guidelines and standards.

The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. Growing public awareness and concern for controlling water pollution led to sweeping amendments in 1972. As amended in 1972, the law became commonly known as the Clean Water Act (CWA). The CWA underwent significant reorganization and expansion in 1972, with subsequent major amendments in 1977 and 1987. The CWA does not specifically address the contamination of groundwater resources, a subject addressed by provisions in other laws, including the Safe Drinking Water Act and the Resource Conservation and Recovery Act.

Each federal agency having jurisdiction over any facility or engaged in activity resulting, or which may result, in the discharge or runoff of pollutants is subject to, and must comply with, all Federal, State, interstate, and local requirements and administrative authorities for the control and abatement of water pollution, including reasonable service charges. This includes adhering to any reporting, record-keeping, and/or permitting requirements. If the President determines it to be in the paramount interest of the United States, he may exempt any effluent source of any department, agency, or instrumentality in the Executive Branch. The President may issue an exemption from compliance with any requirements of CWA for a 1-year period, except for the National Standards of Performance, the Toxic and Pretreatment Effluent Standards, and the National Pollutant Discharge Elimination System (NPDES) permit program.

Funding and grants

The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. It created a comprehensive set of water quality programs and provided financing for state and local governments. The Public Health Service provided financial and technical assistance.

The 1972 amendments to the Act, now commonly known as the Clean Water Act (CWA), provided for federal funds to support 75% of the capital cost of municipal sewage treatment plants, with states and local funds providing the remaining 25%. In 1981, Congress reduced the federal funding proportion for most grants to 55%.

The 1987 Water Quality Act (WQA) amendments transitioned to a revolving loan program. The Clean Water State Revolving Fund (CWSRF) program replaced the municipal construction grants program. Under the CWSRF, federal funds are provided to the states and Puerto Rico to capitalize their respective revolving funds, which are used to provide financial assistance (loans or grants) to local governments for wastewater treatment, nonpoint source pollution control, and estuary protection. The states contribute an additional 20% to match the federal grants. The CWSRF is primarily used for wastewater treatment infrastructure, but there are also eligibilities related to source water protection. The program's average interest rate was 1.4% nationwide in 2017, compared to an average market rate of 3.5%.

The 1987 amendments to the CWA also established the Section 319 Nonpoint Source Management Program, which addresses the need for greater federal leadership to help focus state and local nonpoint source efforts. Under Section 319, states, territories, and tribes receive grant money to support a wide variety of activities, including technical and financial assistance, education, training, technology transfer, demonstration projects, and monitoring to assess the success of specific non-point source implementation projects. The CWA also established the Water Quality Monitoring Grants program, authorizing the EPA to provide financial assistance in the form of water pollution control (Section 106) grants. Section 106 grants provide funding to build and sustain effective water quality programs that ensure the health of the nation's water bodies.

Pollution sources

The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. However, it only took on its modern form when it was completely rewritten in 1972, in an act called the Federal Water Pollution Control Act Amendments of 1972. This was in response to growing public awareness and concern for controlling water pollution.

The Clean Water Act (CWA) regulates discharges of pollutants into US waters and controls pollution by means of wastewater standards for industry, national water quality criteria recommendations for surface waters, and the National Pollution Discharge Elimination System (NPDES) permit program. The CWA also establishes conditions and permitting for discharges of pollutants into the waters of the United States.

The CWA made it unlawful for any person to discharge any pollutant from a point source into waters of the United States, unless an NPDES permit was obtained under its provisions. Under the CWA, the Environmental Protection Agency (EPA) issues technology-based effluent guidelines that establish discharge standards based on treatment technologies that are available and economically achievable. The EPA also regulates all waste streams generated from offshore oil and gas activities, primarily by general permits.

The CWA includes three broad categories of pollutants: conventional, toxic, and non-conventional. Conventional pollutants are contained in the sanitary wastes of households, businesses, and industries. These include fecal coliform, total suspended solids, biochemical oxygen demand, pH, and oil and grease (e.g. hydrocarbons, fats, oils, waxes, and high-molecular fatty acids). Toxic pollutants include certain chemicals and heavy metals, such as mercury, lead, and pesticides. Non-conventional pollutants are those that do not fall into the other two categories, such as radioactive substances and some emerging contaminants.

The CWA has been amended several times since its enactment, including through the Clean Water Act of 1977 and the Water Quality Act (WQA) of 1987, to address changing needs and challenges in water pollution control.
