Government Action Plan: Tackling Pollution

Pollution has been a problem since the appearance of our earliest ancestors, and it continues to be a pressing issue today. In response to the growing concerns about pollution, governments around the world have implemented various measures to combat this issue. For instance, the US government passed the Clean Air Act, which aims to reduce air pollution through state and federal regulations, and the Clean Water Act, which provides funding to improve sewage treatment plants and sets limits on industrial discharges into water bodies. Similarly, India has introduced the National Clean Air Programme (NCAP), which focuses on improving air quality in cities that fail to meet standards. These initiatives demonstrate the efforts made by governments to address pollution and protect public health and the environment.

The Clean Air Act

One of the goals of the Act was to set and achieve NAAQS in every state by 1975, addressing the risks posed by widespread air pollutants. The Act directed states to develop state implementation plans (SIPs) to achieve these standards, applicable to industrial sources. The Clean Air Act has been amended multiple times, including in 1977 and 1990, to set new deadlines for achieving NAAQS as many areas failed to meet the initial targets.

The 1990 amendments to the Clean Air Act were particularly significant. They aimed to curb four major threats to the environment and public health: acid rain, urban air pollution, toxic air emissions, and stratospheric ozone depletion. The 1990 amendments established a national operating permits program and strengthened enforcement to ensure better compliance. The Acid Rain Program (ARP), a cap-and-trade emissions program, was also established under these amendments to reduce sulfur dioxide and nitrogen oxide emissions from power plants.

The Clean Water Act

The basis of the CWA was enacted in 1948 as the Federal Water Pollution Control Act, but it took on its modern form when it was significantly reorganized and expanded in 1972. The 1972 amendments established the basic structure for regulating pollutant discharges into the waters of the United States. It gave the Environmental Protection Agency (EPA) the authority to implement pollution control programs, such as setting wastewater standards for industries. The CWA made it unlawful to discharge any pollutant from a point source into navigable waters without a permit. The EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls these discharges.

The CWA also introduced funding for publicly owned treatment works to improve wastewater treatment and maintain the integrity of wetlands. For instance, to assist municipalities in building or expanding sewage treatment plants, Title II of the CWA established a system of construction grants, with federal funds supporting 75% of project costs. The CWA further led to the development of national water quality criteria recommendations for pollutants in surface waters.

The Federal Government's role

The Clean Air Act

The Clean Air Act, passed in 1970, is a comprehensive federal law that gives the Environmental Protection Agency (EPA) the authority to regulate air pollutants and polluting industries. The act sets national ambient air quality standards, which are mandatory for state and tribal governments to meet and maintain. The EPA is responsible for establishing federal plans that directly regulate pollution sources if state plans fall short. The Clean Air Act Amendments of 1977 expanded the scope of the original act by including provisions to protect areas with clean air and tightening rules around automobile emissions. The 1990 amendments further strengthened the act, focusing on cost-effective approaches to reducing air pollution and addressing acid rain and ozone depletion.

The Federal Water Pollution Control Act

The Federal Water Pollution Control Act, commonly known as the Clean Water Act, was enacted in 1972 after a major fire on the Cuyahoga River. This legislation provides funding to improve sewage treatment plants and sets limits on the discharge of pollutants into water by industries and treatment plants. It also led to the creation of federal and state environmental protection agencies and the Oil Pollution Act of 1990, which prohibits the discharge of oil into navigable rivers.

The Air Pollution Control Act

The Air Pollution Control Act of 1955 was the first federal attempt to control air pollution. This act laid the groundwork for subsequent clean air legislation, which has been revised and strengthened over time.

Environmental Protection Agency (EPA)

The EPA plays a crucial role in enforcing pollution control measures. They set emission standards for various sources, including vehicles, heavy-duty trucks, buses, construction equipment, and industrial facilities. The EPA also works closely with state, local, and tribal governments to implement pollution reduction plans. They provide guidance, technical assistance, and reviews to ensure compliance with the Clean Air Act and other environmental regulations.

State and Tribal Governments

While the federal government sets the standards, state and tribal governments are responsible for implementing and enforcing pollution control measures. State implementation plans (SIPs) must outline how each state intends to meet the national air quality standards. Tribal governments can also play a significant role in administering Clean Air Act programs if they meet certain criteria.

In summary, the federal government's role in reducing pollution has been instrumental in improving air and water quality, protecting public health, and combating climate change through various acts, amendments, and the establishment of the EPA. State and tribal governments work in partnership with the federal government to implement and enforce these measures, ensuring a healthier environment for Americans.

State and tribal governments' role

State governments have played a crucial role in addressing pollution, particularly in implementing and enforcing environmental protection laws and regulations. For instance, state emission control measures, in conjunction with the EPA's national emission standards, have significantly improved air quality and public health. The Clean Air Act, enacted in 1970, granted the EPA the authority to regulate pollution from transportation, leading to the development and implementation of emission standards for various vehicles and equipment. This has resulted in a dramatic reduction in pollution levels, with new cars, SUVs, and pickup trucks being approximately 99% cleaner for common pollutants compared to 1970 models.

Additionally, states have been active in reducing water pollution. The Federal Water Pollution Control Act of 1972, also known as the Clean Water Act, was established to improve sewage treatment plants and set limits on industrial discharges into the water. This legislation was a response to the Cuyahoga River fires in 1969, which highlighted the urgent need to address water pollution.

Moreover, state governments have worked collaboratively with the EPA to cut interstate air pollution, further improving air quality and helping downwind states meet health-based standards for fine particles and ozone.

Tribal governments have also been actively involved in environmental protection efforts through partnerships with the EPA. The EPA's Indian Policy aims to protect human health and the environment in Indian Country, giving special consideration to tribal interests and ensuring the involvement of tribal governments in decision-making processes. The Safe Drinking Water Act of 1986 allowed eligible tribes to implement water supervision and control programs, with the EPA approving tribal regulations. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or "Superfund," was amended the same year to grant tribes a substantial role in responding to releases of hazardous substances and pollutants.

The Clean Water Act and Clean Air Act amendments of 1987 and 1990, respectively, further expanded tribal authority by authorizing the EPA to approve eligible tribes to administer programs establishing tribal standards for water and air quality. The EPA's American Indian Environmental Office conducts training for EPA staff to enhance understanding and communication with tribal governments, ensuring that environmental policies integrate tribal considerations.

The EPA's standards

The Environmental Protection Agency (EPA) has been instrumental in reducing pollution and protecting public health and the environment. The EPA was given legal authority to regulate pollution from transportation, including cars, trucks, buses, and other vehicles, following the passing of the Clean Air Act in 1970. This Act has been amended several times, with the most recent amendment occurring in 1990, and has significantly reduced pollution released into the environment.

The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for six principal pollutants, or "criteria" air pollutants, which can be harmful to public health and the environment. These six common air pollutants are particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The EPA designates areas as meeting (attainment) or not meeting (nonattainment) these standards, and states are required to develop plans to attain and maintain the NAAQS in their respective areas.

The EPA has successfully phased out lead in motor vehicle gasoline, resulting in a 94% decrease in atmospheric lead levels between 1980 and 1999. This has led to significant health benefits, as lead pollution was a widespread health concern. Additionally, sulfur levels in fuels have decreased by more than 90%, and new cars, SUVs, and pickup trucks are now approximately 99% cleaner for common pollutants compared to 1970 models.

The EPA has also implemented emission standards for passenger vehicles, heavy-duty trucks, buses, construction and farm equipment, locomotive and marine engines, and even lawn and garden equipment. These standards have encouraged the development of new emission control technologies and innovations in the auto industry. The EPA is now tackling the critical challenge of climate change and is working to develop carbon emissions standards for aircraft.

The EPA's Clean Air Markets Division (CAMD) administers programs that reduce air pollution from power plants, addressing issues such as acid rain, ozone depletion, and particle pollution. The EPA also works with states and tribes to ensure that the NAAQS are met and maintained. The Clean Air Act requires the EPA to create a list of stationary sources of air pollution and establish Federal New Source Performance Standards (NSPS) for new sources, including equipment specifications and operation requirements.
