Summary of the Clean Water Act

The Water Quality Purification Act (CWA) regulates the emission of pollutants into water bodies in the United States and establishes the basic structure for regulating the water quality standards of surface water. The foundation of CWA was promulgated in 1948 and called the Federal Water Pollution Control Law, but the bill was greatly restructured and expanded in 1972. The water purification law became the general name of the bill and was amended in 1972.

According to CWA, EPA implements a pollution prevention plan such as setting industrial wastewater standards. The US Environmental Protection Agency also formulated national water quality standards for surface water pollutants.

It is illegal for CWA to discharge pollutants emitted from point sources into navigable waters, unless permission is obtained. The National Environmental Protection Agency's National Pollutant Release Control System (NPDES) enables you to manage emissions volumes programmatically. Point light sources are individual vehicles such as pipes and artificial grooves. NPDES license is not necessary to connect to the local government's system, purification system, or individual's residence without discharge from the ground but if industrial facilities, local governments, and other facilities directly discharge to surface water, You need to obtain a license.

In order to ensure the safety of drinking water, to protect human health, to support economic activities and entertainment activities and to provide healthy habitat for fish, plants and wildlife, the Water Resources Bureau (OW) Restore the sea, basin and their aquatic ecosystems.

The EPA Watershed Academy offers training courses on regulations, watershed protection, and other clean water resource resources.

Article 401 of the Water Quality Purification Act (CWA) shall provide evidence that the emission from the facility conforms to the law, including national water quality standards, to the applicant of the Federal government license or license Is required. A controversy is emerging as to the exercise of this power by the State in protecting water quality. In most cases, the discussion on 401 authentication issues is a discussion between the state and the benefits of hydroelectric power generation. The 1994 Supreme Court decision endorsed the state authority in this area and disappointed development and hydropower interest groups. The court reconsidered these issues in the 2006 ruling that unanimously exercised Article 401 to maintain state jurisdiction over hydropower authorization permits. The dispute over the power of Article 401 between the state and the industrial organization is a repeated legislative issue, but Congress has not yet modified the scope of the provision.

The Water Qualification Purification Act (CWA), also known as the Federal Water Pollution Control Law amendment in 1972, was enacted under US law in 1972 to restore and maintain clean and healthy water. CWA is a countermeasure to the growing public concern about the state of the environment and the country's watershed. This was a major revision of the Federal Water Pollution Control Act of 1948, which turned out to be ineffective. CWA itself was revised in 1977 to regulate the discharge of untreated wastewater from municipalities, industries, companies into rivers, lakes and coastal waters.

1969 and 1972 - California 's 1969 Porter - Cologne Act and the 1972 Federal Water Pollution Control Law amendment constitute the Contemporary Water Pollution Control Act (CWA), and the California State Water Management Committee (SWRCB) Water Quality and Other Useful Applications The Porter Koeln law was quickly recognized as one of the most powerful pollution control laws in the United States. Through it SWRCB and the nine regional committees have been given extensive responsibility and authority to protect and strengthen all beneficial uses of state complex water functions. Because the new State Law is very influential, Congressional authors have used part of it as the basis for revising the 1972 Federal Water Pollution Control Law. This is often called the water purification law.
