Water Pollution Control: State Agency's Role And Responsibility

Water pollution is a pressing issue that is regulated by various state agencies. The Environmental Protection Agency (EPA) is the primary agency responsible for enforcing federal clean water and safe drinking water laws. They work to control water pollution through various programs and guidelines, such as the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). The EPA also collaborates with states and local communities to address water-related issues, providing support and resources to ensure access to safe and clean water for all Americans. Additionally, state-specific agencies like the Michigan Department of Environment, Great Lakes, and Energy (EGLE) play a crucial role in enforcing federal and state drinking water requirements, further highlighting the importance of collective efforts in tackling water pollution.

The Clean Water Act (CWA)

The CWA establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. Under the CWA, the Environmental Protection Agency (EPA) has implemented pollution control programs such as setting wastewater standards for industry and water quality standards for all contaminants in surface waters. The CWA made it unlawful to discharge any pollutant from a point source into navigable waters, unless a National Pollutant Discharge Elimination System (NPDES) permit was obtained. The EPA's NPDES permit program controls discharges. The EPA issues technology-based effluent guidelines that establish discharge standards based on available and economically achievable treatment technologies. Each EPA region issues permits that meet or exceed the guidelines and standards.

The CWA does not specifically address groundwater contamination, which is covered by other laws such as the Safe Drinking Water Act and the Resource Conservation and Recovery Act. However, the EPA enforces federal clean water and safe drinking water laws, and the Office of Water (OW) within the EPA ensures drinking water safety and restores and maintains oceans, watersheds, and aquatic ecosystems.

The Oil Pollution Act of 1990 (OPA 90) amended the CWA, strengthening requirements for contingency planning and increasing penalties for noncompliance. OPA 90 also preserved state authority to establish laws governing oil spills. The CWA also regulates mining operations, including discharges of pollutants from valley fills and the valley fills themselves, where rock and dirt are placed in streams and wetlands.

Safe Drinking Water Act (SDWA)

In the United States, the Environmental Protection Agency (EPA) enforces federal clean water and safe drinking water laws. The Safe Drinking Water Act (SDWA) is the primary federal law that ensures the quality of Americans' drinking water. The SDWA was originally passed by Congress in 1974 to protect public health by regulating the nation's public drinking water supply.

The SDWA authorizes the EPA to establish minimum standards to protect the quality of drinking water, using detailed risk and cost assessments. It requires all public water systems to comply with these primary (health-related) standards, including protection from underground injection. The EPA has established protective drinking water standards for more than 90 contaminants, including arsenic, lead, and microbial pathogens. Over 92% of the population supplied by community water systems receive drinking water that meets all health-based standards.

The SDWA applies to every public water system in the United States, currently over 148,000 systems providing water to almost all Americans at some point in their lives. The Act does not cover private wells or bottled water, which is regulated by the Food and Drug Administration (FDA). Small water systems are given special consideration and resources under the SDWA to ensure they have the managerial, financial, and technical ability to comply with drinking water standards.

The Office of Ground Water and Drinking Water (OGWDW) works with states, tribes, and other partners to protect public health by ensuring safe drinking water and protecting groundwater. The OGWDW oversees the implementation of the SDWA, with state governments also playing a role in encouraging the attainment of secondary (nuisance-related) standards. The EPA also takes part in pollution prevention efforts aimed at protecting sources of drinking water, such as through the National Pollutant Discharge Elimination System (NPDES) and the Underground Injection Control Program.

State and federal roles

The Clean Water Act (CWA) is the primary federal legislation governing water pollution control in the United States. The Act, first passed in 1948 and significantly expanded in 1972, establishes the basic structure for regulating the discharge of pollutants into US waters and sets quality standards for surface waters. The Environmental Protection Agency (EPA) is the primary federal agency responsible for implementing and enforcing the CWA, in coordination with state governments.

Under the CWA, the EPA has implemented several pollution control programs, including the National Pollutant Discharge Elimination System (NPDES). The NPDES sets permit requirements for discharges from point sources, such as municipal and industrial facilities, into US waters. The EPA also provides support for municipal wastewater treatment plants and takes part in pollution prevention efforts aimed at protecting watersheds and sources of drinking water. In addition, the EPA sets standards for drinking water quality under the Safe Drinking Water Act (SDWA) and oversees the implementation of these standards by states, localities, and water suppliers.

The US Army Corps of Engineers, an agency within the Department of Defense, also plays a role in water pollution control. They are responsible for regulating discharges of dredged or fill material into US waters, as well as managing navigable waterways and wetlands.

At the state level, individual states have the authority to establish their own water quality standards and issue permits for discharges within their jurisdictions, provided they meet or exceed the requirements set by the EPA. States are also responsible for implementing and enforcing federal standards and programs, such as the NPDES, at the local level.

Other federal agencies with roles in water pollution control include the Bureau of Ocean Energy Management (BOEM), which oversees offshore energy development and enforces spill prevention measures for oil and gas facilities, and the National Oceanic and Atmospheric Administration (NOAA), which conserves and protects living marine resources, particularly in California through the NMFS.

EPA's role and responsibilities

The Environmental Protection Agency (EPA) is a federal agency established by the US government. It is a regulatory body responsible for overseeing and enforcing environmental policies and regulations. The EPA's primary focus is on safeguarding human health and the environment, and it plays a vital role in shaping and implementing initiatives to address pressing environmental challenges.

The EPA's role and responsibilities include developing and enforcing regulations to mitigate environmental pollution and protect natural resources. The agency sets standards and guidelines to ensure that industries, businesses, and individuals comply with environmental regulations and promote responsible practices. This includes monitoring and reducing air pollution from industrial facilities, vehicles, and power plants, as well as addressing water pollution and hazardous waste management.

The EPA enforces federal clean water and safe drinking water laws, such as the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). Under the CWA, the EPA regulates waste streams generated from offshore oil and gas activities and provides funding for the construction of sewage treatment plants. The EPA also issues technology-based effluent guidelines that establish discharge standards based on available and economically achievable treatment technologies. The NPDES permit program, created by the EPA in 1972, addresses water pollution by regulating point sources that discharge pollutants into US waters.

The EPA also provides support for municipal wastewater treatment plants and takes part in pollution prevention efforts aimed at protecting watersheds and sources of drinking water. This includes helping states develop pollution control plans and providing financial and technical assistance to monitor water quality and identify water pollution problems. The EPA conducts extensive research and analysis to gather data, assess environmental risks, and identify potential threats. Through scientific studies and technological advancements, the agency works to enhance its understanding of environmental challenges and develop effective mitigation strategies.

Overall, the EPA plays a crucial role in protecting water resources and ensuring the quality of drinking water through regulation, enforcement, research, and collaboration with other agencies and states.
