The Clean Air Act vs. Pollution

There is always a problem of breathing in fresh air that is not contaminated, which can be traced back to the industrial revolution, so we need to pay attention to the condition of the air breathing every day. Complaints about pollutants in the atmosphere are important health problems. The deaths of 19 people reported in 1948 in Denor, Pennsylvania, were an attractive factor for the Washington Group simply because they wanted to regulate industrial waste by combining combustion products and heat inversion. These people are still dead. (Fleham)

The 1970 air purification law is a US federal law aimed at reducing air pollution and protecting the air quality. This law was revised substantially in 1990 and 2003, involving the surrounding air pollution (outdoor air pollution) and the source-specific air pollution (which can trace back to identifiable sources such as factories and automobiles) Did. The air purification law sets air quality standards that limit the amount of various pollutants to a specific level. In addition, the Air Pollution Control Law stipulates the deadline for government and industry to meet standards. Although the Federal Environmental Protection Agency (EPA) ultimately sets the standards and is responsible for implementing the Air Pollution Control Law, most of the daily work in air pollution is done at the state and local levels.

Despite the dramatic progress of clean air since 1970, the air pollution in the United States continues to endanger the health and the environment of people. Under the Atmospheric Remediation Act, EPA works with states, local governments, tribal governments, other federal agencies, and stakeholders to alleviate air pollution and its damage. However, even if it can not be seen, air pollution can be harmful. Recent scientific research has shown that some pollutants may endanger public health and welfare even with low levels of pollution. The US Environmental Protection Agency has recently revised five of the six common pollutants that meet domestic air quality standards. The EPA makes the standard more protective, as new scientific research with peer review shows that existing standards are not sufficient to protect public health and the environment

In implementing the air purification law, EPA collects scientific information on the effects of air pollution and comprehensively, and functions as a clearing house for emissions, atmospheric quality and air pollution control data. Scientists and technical experts from the US Environmental Protection Agency use various technical tools to analyze the state of the art air pollution problems and policies. The US Environmental Protection Agency and the State will conduct air quality simulation based on the expected change in emissions to predict future air pollution levels. Risk assessment is used to quantify cancer risk and other effects of hazardous air pollutants (see National Atmospheric Toxicity Assessment) and non-cancer risk of common pollutants. EPA will conduct a cost-benefit analysis to compare the cost and benefit of alternative regulatory approaches to society
