EPA is currently reviewing the adequacy of the ozone and PM 10 standards. Largely in response to a court decision in favor of environmentalists Sierra Club v. Ruckelshaus, the amendments included a program for the prevention of significant deterioration PSD of air that was already clean.

This program would prevent polluting the air up to the national levels in areas where the air was cleaner than the standards. In Class I areas, areas with near pristine air quality, no new significant air pollution would be allowed. Class I areas are airsheds over larger national parks and wilderness areas.

In Class II areas a moderate degree of air quality deterioration would be allowed.

And finally, in Class III areas, air deterioration up to the national secondary standards would be allowed. Related to the prevention of significant deterioration is a provision to protect and enhance visibility in national parks and wilderness areas even if the air pollution is not a threat to human health.

The impetus of this section of the bill was the growing visibility problem in parks, especially in the Southwest.

Throughout the s efforts to further amend the Clean Air Act were stymied. President Ronald Reagan was opposed to any strengthening of the Act, which he argued would hurt the economy. In Congress, the controversy over acid rain between members from the Midwest and the Northeast further contributed to the stalemate.

Over the next two years, the issues were hammered out between environmentalists and industry and between different regions of the country. Major amendments to the Clean Air Act were finally passed in the fall of These amendments addressed four major topics: Most of this reduction came from old utility power plants.

The law also creates marketable pollution allowances, so that a utility that reduces emissions more than required can sell those pollution rights to another source. Economists argue that such an approach should become more widespread for all pollution control, to Courtesy of U.

Due to the failure of the toxic air pollutant provisions of the Clean Air Act, new, more stringent provisions were adopted requiring regulations for all major sources of varieties of toxic air pollution within 10 years.

Areas of the country still in nonattainment for criteria pollutants will be given from three to 20 years to meet these standards.

These areas are also required to impose tighter controls to meet these standards. To help these areas and other parts of the country, the act requires stiffer motor vehicle emissions standards and cleaner gasoline.

Finally, three chemical families that contribute to the destruction of the stratospheric ozone layer chlorofluorocarbons [CFCs], hydrochlorofluorocarbons [HCFCs], and methyl chloroform are to be phased out of production and use.

The Clean Air Act has met with mixed success. The national average pollutant levels for the criteria pollutants have decreased. Nevertheless, many localities have not achieved these standards and are in perpetual nonattainment.

Not surprisingly, major urban areas are those most frequently in nonattainment. The pollutant for which standards are most often exceeded is ozone, or smog. A final point of caution concerning evaluating the Clean Air Act: These changes may be due to shifts in the economy at large, changes in weather patterns, or other such variables.

In those cases where topography is a factor in air movement, AQCRs often correspond with airsheds.

AQCRs may consist of two or more cities, counties, or other governmental entities, and each region is required to adopt consistent pollution control measures across the political jurisdictions involved.

AQCRs may even cross state lines and, in these instances, the states must cooperate in developing pollution control strategies. As ofmost AQCRs had achieved national air quality standards; however the remaining AQCRs where standards had not been achieved were a significant group, where a large percentage of the United States population dwelled.

AQCRs involving major metro areas like Los Angeles, New York, Houston, Denver, and Philadelphia were not achieving air quality standards because of smog, motor vehicle emissions, and other pollutants. OZONE Ozone O 3 is a toxic, colorless gas but can be blue when in high concentration with a characteristic acrid odor.

A variant of normal oxygen, it has three oxygen atoms per molecule rather than the usual two. Ozone strongly absorbs ultraviolet radiation at wavelengths of — nanometers nm with peak absorption at The concentration of ozone in the ozonosphere is 1 molecule permolecules, or if the gas were at standard temperature and pressure, the ozone layer would be 0.

Ozone in the stratosphere results from a chemical equilibrium between oxygen, ozone, and ultraviolet radiation.

Ultraviolet radiation is absorbed by oxygen and produces ozone. Simultaneously, ozone absorbs ultraviolet radiation and decomposes to oxygen and other products. Ozone layer depletion occurs as a result of complex reactions in the atmosphere between organic compounds that react with ozone faster than the ozone is replenished.

Compounds of most concern include the byproducts of ultraviolet degradation of chlorofluorocarbons CFCschlorine, and fluorine.Aug 08,  · A woman wearing a protective pollution mask walks on a street in Beijing on March 20, The last large coal-fired power plant in Beijing has suspended operations, with the city's electricity.

Federal Laws, Guidance, Regulations and Dockets at benjaminpohle.com Laws Alabama is an "authorized" state, meaning that it is authorized by the EPA to administer state environmental law in lieu of most federal environmental laws.

The Clean Air Act (42 U.S.C. § ) is a United States federal law designed to control air pollution on a national level.

SCHEDULE I

It is one of the United States' first and most influential modern environmental laws, and one of the most comprehensive air quality laws in the world. As with many other major U.S. federal environmental statutes, it is administered by the U.S.

Environmental Protection. Apr 18,  · The annual State of Global Air Report was published on Tuesday by the Health Effects Institute and it found that over 95 percent of the world's population is breathing unhealthy air while long.
