Programs and Activities[ edit ] Graph showing decreases in US air pollution concentrations during to Part A: Air Quality and Emissions Limitations[ edit ] This section of the act declares that protecting and enhancing the nation's air quality promotes public health.

The law encourages to prevent regional air pollution and control programs. It also provides technical and financial assistance for preventing air pollution at both state and local governments. Additional sub chapters cover cooperation, research, investigation, training, and other activities.

Grants for air pollution planning and control programs, and interstate air quality agencies and program cost limitations are also included in this section. Non-attainment areas do not meet national standards for primary or secondary ambient air quality.

Attainment areas meet these standards, while unclassified areas cannot be classified based on the available information. The list of hazardous air pollutants that the act establishes includes compounds of AcetaldehydebenzenechloroformPhenoland selenium. The list also includes mineral fiber emissions from manufacturing or processing glass, rock or slag fibers as well as radioactive atoms.

The list can periodically be modified. The act lists unregulated radioactive pollutants such as cadmiumarsenicand poly cyclic organic matter and it mandates listing them if they will cause or contribute to air pollution that endangers public health, under section or Measures to prevent unemployment or other economic disruption include using local coal or coal derivatives to comply with implementation requirements.

The final sub chapter in this act focuses on land use authority. Ozone Protection[ edit ] Because of advances in the atmospheric chemistry, this section was replaced by Title VI when the law was amended in Ozone exists naturally in the stratospherenot the troposphere.

It is laterally distributed because it is destroyed by strong sunlight, so there is more ozone at the poles. Ozone is created when O2 comes in contact with photons from solar radiation. Therefore, a decrease in the intensity of solar radiation also results in a decrease in the formation of ozone in the stratosphere.

This exchange is known as the Chapman mechanism: Atmospheric freon and chlorofluorocarbons CFCs contribute to ozone depletion Chlorine is a catalytic agent in ozone destruction.

Following discovery of the ozone hole inthe Montreal Protocol successfully implemented a plan to replace CFCs and was viewed by some environmentalists as an example of what is possible for the future of environmental issues, if the political will is present.

This permitting process, known as New Source Review NSRapplies to sources in areas that meet air quality standards as well as areas that are unclassified. Plan Requirements for Non-attainment Areas[ edit ] Under the Clean Air Act states are required to submit a plan for non-attainment areas to reach attainment status as soon as possible but in no more than five years, based on the severity of the air pollution and the difficulty posed by obtaining cleaner air.

The plan must include: Achieving attainment status makes a request for reevaluation possible. It must include a plan for maintenance of air quality. Emission Standards for Moving Sources[ edit ] Graph showing decreases in US air pollution emissions from transportation sources duringwhile US population and economic activity increased.

Motor Vehicle Emission and Fuel Standards[ edit ] Sub-chapters of Title II cover state standards and grants, prohibited acts and actions to restrain violations, as well as a study of emissions from non road vehicles other than locomotives to determine whether they cause or contribute to air pollution.

Motorcycles are treated in the same way as automobiles under the emission standards for new motor vehicles or motor vehicle engines. The last few sub chapters deal with high altitude performance adjustments, motor vehicle compliance program fees, prohibition on production of engines requiring leaded gasoline and urban bus standards.

The automobile industry argued that it could not meet the new standards [8]. Senators expressed concern about impact on the economy. However the stricter standards led to the creation of the catalytic converter, which was a revolutionary development.

Coincidentally, these converters didn't work well with leaded gas, which contributed to the swift removal of lead from gasoline that was also recognized for having adverse health effects. Aircraft Emission Standards[ edit ] Many volatile organic compounds VOCs are emitted over airports and affect the air quality in the region.

VOCs include benzeneformaldehyde and butadienes which are known to cause health problems such as birth defects, cancer and skin irritation. Hundreds of tons of emissions from aircraft, ground support equipment, heating systems, and shuttles and passenger vehicles are released into the air, causing smog.

Therefore, major cities such as SeattleDenverand San Francisco require a Climate Action Plan as well as a greenhouse gas inventory. Clean Fuel Vehicles[ edit ] Trucks and automobiles play a large role in deleterious air quality.

Harmful chemicals such as nitrogen oxidehydrocarbonscarbon monoxide and sulfur dioxide are released from motor vehicles.• Philippine Clean Air Act-R.A. Section 3 states that: The State shall pursue a policy of balancing development and environmental protection.
