ed. The Clean Air Act of 1970 addressed that need. One part of the federal law set standards for emissions of various chemical compounds from mobile and stationary sources like cars, aircrafts, industries and powerplants. In 1990, the Clean Air Act was changed further restricting release of a broader range of HAPs with lower limits ( Air Pollution / OAR pg. 4). The U.S. Environment Protection Agency ( EPA ) has the authority to identify HAPs and set standards for the amounts of these pollutants that may be emitted without endangering public health ( Gay pg. 12). The Clean Air Act also provided framework for ideas of alternate fuels to be used in cars and airplanes. It promotes the use of clean low sulfur coals and natural gas as well as technologies to clean high sulfur coal. The act also encourages to reduce energy waste and create market for clean fuel. The new law gives states more time to meet the air quality standard, for example up to 20 years for ozone in L.A. It requires states to make constant formidable progress reducing emissions. The act requires the Federal government to reduce emissions from all automobiles, consumer products, and from ships and barges during loading and unloading of petroleum. The new law also establishes a clean fuel car pilot program in California, requiring the phase-in of tighter emission limit for 150,000 vehicles in models 1996 and 300,000 by the model year 1999. These standards can be met with any combination of vehicle technology and cleaner fuels. The standards become stricter in the year 2001 ( Air Pollution / OAR pg. 5 ). With each year passing, the quality of earths air both improves and worsens. While science and technology makes some advances in the war against pollution, they also create and discover other air pollution problems that the world was unaware of previously. The growth of population is also a major factor for the increase of air pollution ( Gutnik pg. 49 ). To con...
