The US has regulated pollution through various laws and amendments enacted over time. The Air Pollution Control Act of 1955 was the first federal legislation addressing air pollution, raising awareness about the hazards of air pollution and setting emissions standards. The Clean Air Act of 1963 further established a federal program for research and control. The Federal Water Pollution Control Act of 1948 was the first major law addressing water pollution, with amendments in 1972 leading to the Clean Water Act, which established a framework for regulating pollutant discharges. Amendments to the Clean Air Act in 1970, 1977, and 1990 significantly expanded federal authority and implemented comprehensive regulations for air quality and emissions, including the National Ambient Air Quality Standards (NAAQS). These laws and amendments have played a crucial role in reducing pollution and protecting public health in the US.

The Clean Air Act
The 1990 amendments further increased the authority and responsibility of the federal government. New regulatory programs were authorized for the control of acid deposition (acid rain) and the issuance of stationary source operating permits. The NESHAPs were incorporated into an expanded program for controlling toxic air pollutants, and provisions regarding stratospheric ozone protection were also included. The 1990 amendments also established a national operating permits program and strengthened enforcement to ensure better compliance with the Act.
The six major pollutants regulated by the NAAQS under the Clean Air Act are ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. The Act also includes technology-based emissions standards, which are based on the latest and most efficient technologies for controlling pollution from various sources. For example, the Acid Rain Program (ARP) is an emissions trading program aimed at reducing sulfur dioxide and nitrogen oxide emissions from power plants, the primary contributors to acid rain.

The Clean Water Act
The 1972 amendments established the basic structure for regulating pollutant discharges into US waters. It gave the Environmental Protection Agency (EPA) the authority to implement pollution control programs such as setting wastewater standards for industry. It also maintained existing requirements to set water quality standards for all contaminants in surface waters. The Act made it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit was obtained under its provisions.
The 1972 amendments also funded the construction of sewage treatment plants under the construction grants program. Title I of the Act includes a Declaration of Goals and Policy and various grant authorizations for research programs and pollution control programs. Title II established a system of construction grants, with federal funds supporting 75% of project costs. In 1981, Congress reduced the federal funding proportion for most grants to 55%.

The Air Pollution Control Act of 1955
The Act was the culmination of much research done on fuel emissions by the federal government in the 1930s and 1940s. It provided funds for federal research into air pollution, with a total of $5 million granted to the Public Health Service for a five-year period to conduct this research. According to a source, the amount was $3 million allotted per year for the five-year research period. This funding was used to research ways to control air pollution from its source.
The Act allowed Congress to reserve the right to address the growing problem of air pollution. It began to inform the public about the hazards of air pollution and detailed new emissions standards. Despite this, the legislation had no regulation component, and the federal government could not actively combat air pollution by punishing polluters. The Act set up the role that the government would play in researching the effects of air pollution and controlling it.

The National Environmental Policy Act
The basic policy of NEPA is to ensure that all branches of the government consider the environmental implications of their actions before undertaking any major federal action that could significantly impact the environment. This includes the construction of airports, buildings, military complexes, highways, and parkland purchases.
NEPA requires federal agencies to prepare detailed statements, commonly known as Environmental Impact Statements (EIS) and Environmental Assessments (EA), assessing the environmental impact of and alternatives to major federal actions. These statements evaluate the environmental, social, and economic effects of proposed actions, and agencies are required to provide opportunities for public review and comment.

The Federal Water Pollution Control Act of 1948
Secondly, the Act recognised the importance of waste treatment by authorising the Federal Works Administrator to assist states, municipalities, and interstate agencies in constructing treatment plants. These plants were crucial for preventing the discharge of inadequately treated sewage and other wastes into interstate waters or tributaries.
The Act also maintained existing requirements to set water quality standards for all contaminants in surface waters. It made it unlawful for any person to discharge any pollutant from a point source into navigable waters without obtaining a permit under the Act's provisions. This permit system helped regulate and control the release of pollutants into water bodies.
Since its enactment, the Federal Water Pollution Control Act of 1948 has undergone extensive amendments. These amendments have authorised additional water quality programs, standards, and procedures to further enhance water quality and govern allowable discharges. Additionally, funding has been provided through construction grants or general program funding to support the implementation of these initiatives.
