The EPA uses voluntary partnership programs and regulatory programs to protect public health and the environment
The Environmental Protection Agency (EPA) employs a combination of voluntary partnership programs and regulatory programs to safeguard public health and the environment. The EPA's mission is to protect human health and the environment, and it pursues this goal through various initiatives and collaborations.
One of the key regulatory authorities granted to the EPA is the Clean Air Act, which has been expanded and amended over the years. The Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants, known as criteria air pollutants. These pollutants include particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The EPA works with state, tribal, and local air agencies to achieve and maintain these standards across the country. Additionally, the Clean Air Act partnership programs aim to reduce conventional air pollution, improve energy efficiency, and save lives. For example, the EPA has taken steps to limit emissions from aircraft, resulting in significant reductions in sulfur content in gasoline and diesel fuel.
The EPA also has other regulatory programs, such as the Beaches Environmental Assessment and Coastal Health (BEACH) Act, which focuses on protecting coastal recreational waters. The EPA develops criteria to test and monitor water quality and notify the public of any concerns. They also have specific geographic programs like the Chesapeake Bay Program and the National Estuary Program.
In addition to its regulatory programs, the EPA utilizes voluntary partnership programs to achieve its goals. One such program is the Burn Wise Partnership Program, which educates the public on ways to reduce air pollution from wood-burning appliances. The Community-Based Childhood Asthma Program is another voluntary initiative that promotes best practices to reduce the adverse health outcomes and economic burden of asthma. The EPA also has energy-focused programs like ENERGY STAR, which encourages the adoption of energy-efficient products and practices, and the Combined Heat and Power (CHP) Partnership, which promotes the use of efficient and clean power generation technologies.
Furthermore, the EPA engages in public-private industry partnerships through its Voluntary High Global Warming Potential Programs. These partnerships aim to reduce emissions of potent greenhouse gases, such as perfluorocarbons (PFCs) and hydrofluorocarbons (HFCs). The Mobile Air Conditioning Climate Protection Partnership is one such initiative, working to improve the energy efficiency of mobile air-conditioning systems and reduce refrigerant leakage.

The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS)
The Clean Air Act (CAA) is a comprehensive federal law that regulates air emissions from stationary and mobile sources. It was established in 1970 and has been amended several times since, with the most recent amendment occurring in 1990. The Act recognises the right to healthful air quality for all Americans and aims to protect public health and welfare by reducing air pollution.
The Clean Air Act requires the Environmental Protection Agency (EPA) to set National Ambient Air Quality Standards (NAAQS) to address the risks posed by widespread air pollutants. These standards specify the acceptable levels of certain air pollutants in the ambient air in the United States. The six major pollutants regulated by the NAAQS are ozone (O3), particulate matter (PM), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), and lead (Pb). These pollutants are known as the six criteria pollutants and are found all over the US, posing risks to health, the environment, and property.
The EPA works with state, tribal, and local air agencies to attain the NAAQS throughout the country. The Clean Air Act also requires the government to review, update, and enforce these standards. While ensuring compliance with the NAAQS is largely left to the states, the EPA must approve each state's implementation plan and can take over enforcement if a state's plan is not acceptable.
In addition to the NAAQS, the Clean Air Act established other programs to tackle air pollution, including the New Source Performance Standards (NSPS) and the National Emissions Standards for Hazardous Air Pollutants (NESHAPs). The EPA has also taken steps to limit greenhouse gas emissions from aircraft and reduce sulfur content in gasoline and diesel fuel.

The EPA has taken steps to limit emissions from aircraft, reducing GHG emissions
The Environmental Protection Agency (EPA) has been taking steps to limit emissions from aircraft, thereby reducing GHG emissions. In 2016, the EPA finalized findings that GHG emissions from certain classes of engines used in aircraft contribute to air pollution, which causes climate change and endangers public health and welfare. This was done under section 231(a) of the Clean Air Act.
The EPA has also been working with the International Civil Aviation Organization (ICAO) to find the best way to regulate CO2 emissions from airplanes. In 2021, the EPA adopted greenhouse gas (GHG) emission standards for certain classes of engines used by civil subsonic jet airplanes with a maximum takeoff mass greater than 5,700 kilograms and civil larger subsonic propeller-driven airplanes with turboprop engines having a maximum takeoff mass greater than 8,618 kilograms. These standards are equivalent to the ICAO's airplane carbon dioxide (CO2) standards adopted in 2017 and apply to both new type design airplanes and in-production airplanes.
The EPA has also been collaborating with the National Highway and Traffic Safety Administration to issue national greenhouse gas emission standards and fuel economy standards for cars and light trucks, which will further reduce GHG emissions. Additionally, the EPA has implemented the National Clean Diesel Campaign, which reduces diesel emissions for existing engines that the EPA does not regulate, and the Clean School Bus USA initiative, which aims to minimize pollution from school buses.
Furthermore, the EPA has taken steps to reduce sulfur content in gasoline and diesel fuel, cut down on mobile and industrial pollution sources, and protect the ozone layer, all of which contribute to reducing GHG emissions from aircraft and other sources. These actions demonstrate the EPA's commitment to reducing emissions and improving public health and welfare.

The EPA encourages and supports state, tribal, and local agencies in implementing area-wide air toxics strategies
The EPA works with state, tribal, and local agencies to implement area-wide air toxics strategies and protect public health and the environment. The Clean Air Act, for instance, requires the EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants, which include particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The EPA also addresses criteria air pollutants, which can be found throughout the US and harm human health, the environment, and cause property damage.
The EPA also provides community-scale air toxics ambient monitoring grants and supports programs like Community Action for a Renewed Environment (CARE). The CARE program assists communities in forming local partnerships and empowers them to address environmental issues through community-driven problem-solving. These initiatives demonstrate the EPA's commitment to working with state, tribal, and local agencies to implement effective area-wide air toxics strategies.
Furthermore, the EPA has taken steps to reduce emissions from aircraft and new industrial facilities. In 2016, the EPA concluded that GHG emissions from specific aircraft engine classes contribute to air pollution, endangering public health and welfare. The EPA has also mandated that good pollution control measures be incorporated into the design and construction of new industrial facilities, ensuring that the country's industrial base becomes cleaner over time. These actions demonstrate the EPA's comprehensive approach to addressing air pollution and supporting local agencies in their efforts to improve air quality.

The EPA is trying to end the requirement for big polluters to report emissions
The EPA has been working to reduce emissions and improve air quality through various initiatives and regulations. One such initiative is the Greenhouse Gas Reporting program, implemented by President Barack Obama's administration in 2009, which requires large carbon polluters like refineries, power plants, and landfills to report their emissions. This program has been successful in reducing emissions from coal-fired plants in Indiana by 60% since 2010.
However, the current EPA, under President Donald Trump, is trying to end this requirement for big polluters to report their emissions. The EPA argues that the reporting requirement is costly and burdensome for the industry. On the other hand, experts warn that eliminating this requirement could lead to a significant increase in emissions as companies would no longer be publicly accountable for their actions. Additionally, losing this data while the EPA also cuts air quality monitoring could hinder efforts to combat climate change.
The EPA's attempt to end the reporting requirement comes at a time when much of the country's air remains unmonitored, and air pollution continues to pose risks to public health and the environment. Research has linked poor air quality to various diseases, including asthma, heart disease, and potentially cancer. Near polluting industries, there is often a lack of sufficient data or a lack of will to investigate the health impact of air pollution.
The EPA is also attempting to reclaim funds allocated for air monitoring, including grants aimed at promoting diversity, equity, and inclusion. This has led to backlash, with organizations like CleaneAIRE NC suing the EPA, arguing that access to clean air is a human right. Despite the EPA's claims of reducing the industry's burden, others argue that the reporting requirement is essential for companies to document their emissions and provide a baseline for improvement.
Overall, the EPA's move to end the requirement for big polluters to report emissions is controversial, with concerns raised about potential negative impacts on public health, the environment, and the fight against climate change.
