BMAL 560 Name: Michelle Doe Class: BMAL 560 Section: D01 Summer 2013 The Clean Air Act and its Effect on Business Practices and the Environment PRINCIPLE: The Clean Air Act (CAA) is legislation aimed at reducing smog and air pollution (Wikipedia, 2007). o Air pollution is particulate, chemical or biological matter that modifies the natural characteristics of the atmosphere. o Smog is a term that defines fog and smoke in the air at the same time. Is the basic federal law that regulates emissions from multiple sources including area, stationary, and mobile sources (R744, 2007). Authorized the US Environmental Protection Agency (EPA) to develop National Ambient Air Quality Standards (NAAQS). o The states must meet and regulate the NAAQS for air pollutant emissions from all sources, including: Industrial facilities Automobiles (US General Accounting Office, 2007) The purpose is to protect and enhance the quality of the nation’s air and its emission sources while promoting public health and welfare and the nation’s production capacity (Bartelma & Budz, 2007). The goal is to reduce air pollution by 56 billion pounds per year by mainly cutting emissions in large urban areas (AMS, 2007). PRACTICE: (Foundation for Clean Air Progress, 2007) In 1999, a survey stated that since the 1970 CAA amendments, in the US, o Energy consumption grew by 41%. o The population grew by 38%, to 281 million. o Total employment grew by 70%. o The number of registered vehicles grew by 99%. During this time, o Airborne lead emission dropped by 98%. o Particulate matter (PM) emissions dropped 75%. o Volatile organic compound (VOC) emissions dropped by 42%. o Sulfur dioxide (SO 2 ) emissions dropped 39%. o Carbon monoxide emissions (CO) dropped 28%. Trend shows that the CAA and NAAQS helped to create a significant decrease in five of the CAA’s six identified criteria airborne pollutants while the sources of pollution significantly increased. Only nitrogen oxide (NO x ) emissions have increased during this period, but not significantly compared to the growth in the economy, employment, and vehicle usage. Despite these results, 61% of respondents believed air quality was worse, and only 22% believed it was improving. PARTICULARS: CAA Details: Clean Air Act (CAA) of 1990 and amendments was the last significant update to the CAA from its earlier versions. The CAA identified 188 hazardous air pollutants (HAPs), also known as “air toxics” (McCarthy, Hafner, & Montzka, 2006). Page 1 of 9
