Clear Air Act

The Resource Conservation and Recovery Act (RCRA) controls the disposal of ha2ardous waste. SARA Tide III governs the toxic iaventory and emission reporting the Clean Water Act (CWA) sets the limits for metals that can be present ia water discharge and the Clear Air Act (CAA)...

The first clear-air acts in the English-speaking world were implemented by Parliament in 1956, in response to the deadly fog ineidents around London. Since then, the United States government has passed several elean-air acts, including ...

Highly toxic air pollutants fall under Section 112 of the Clean Air Act. Unlike criteria pollutants, these hazardous air pollutants must be controlled to protect the public health with an "ample margin of safety." Implied in this language is the belief in a discrete threshold of exposure below which no effects occur and from which a safety margin can be measured. Subsequent interpretations, however, indicated clearly that Congress did not equate safeguarding the public health with complete risk elimination. 

The Clean Air Act of 1970 established National Ambient Air Quality Standards (NAAQSs) and set New Source Performance Standards (NSPSs) that regulated the amount of emissions to be permitted from a new source in an area. The act also required individual states to create their own state implementation plans (SIPs), and set stiff fines for violation of clean air regulations and established a clear and specific schedule for compliance with the new legislation. A1977 amendment to the act dealt primarily with motor vehicle emission standards. 

One place this problem has become especially severe is the nation s national park system. Visitors to national parks have found their enjoyment of the natural scenery compromised by poor air quality that leaves famous and noteworthy features only barely visible. For this reason, one section of the 1977 Amendments to the Clean Air Act provided for a program of monitoring and pollution control in the nation s 156 national parks and wilderness areas. Poor visibility resulting from high particulate concentration has safety effects also. Automobile drivers and airline pilots may find that they are able to see shorter distances and less clearly, increasing the likelihood of accidents involving other vehicles and aircraft. 

In summary, the prospects of mechanistic-based modelling appear to be several years away. However, it is clear that global reaction models are already losing favor because of their inability to answer current and future questions. We may look back and see the Clean Air Act as the beginning of the need for molecule-based models, where the input and output has to be commensurate with the nature of the questions being asked. 

Hi) Regulatory Authority. Process systems dealing with marine vapor recovery must receive U.S. Coast Guard approval before operation. The ERA is required to establish standards for such systems under the Clean Air Act (Title I and HI). It is not clear to the regulated community who will have final authority for approval. What may be considered a state-of-the-art system today may not meet tomorrow s regulatory requirements. 

However, the great London fog of 1952 that resulted in 4000 deaths refocused attention on the public health consequences of air pollution and the lessons from Donora. The tremendous death toll in London made it clear that air pollution was more than just a nuisance and led to the enactment of legislation on both the state and federal level to control this type of environmental insult. The Commonwealth of Pennsylvania passed a state Clean Air Act in 1955, the first such law to control air pollution. This was followed in 1970 by the passage of the Federal Clean Air Act hearings on this bill were marked by references to the events that happened in Donora in 1948.

Sources can avoid emission reductions through mercury emissions credit trades No limit on CO2 emissions Would practically eliminate new source review for new and existing power plants Would eliminate visibility and interstate air pollution protections, delay attainment of NAAQS and repeal power plant air toxics controls... 

The National Energy Plan calls for a reversal of the Clean Air Act s New Source Review program (targeted in Clear Skies) assumes the need to build at least 1,300 new power plants, mostly fueled by coal and natural gas, over the next 20 years excludes carbon dioxide from a three-pollutant power plant emissions policy and interferes with pending Clean Air Act enforcement cases by ordering a Justice Department review. ...

Another possible reason that a see no evil, hear no evil, speak no evil period persisted was the lack of a clear role for conservation. Scientists were busy quantifying the impacts to biogeochemical processes and impacts on species wherever possible, and policy was aided, and some would say driven, largely by society s response to the negative human impacts that were occurring. The Clean Air Act and its amendments were passed largely without the aid of the conservation community. Apathy in the conservation world could persist at minimal cost when there was no obvious role or need.
