Air-quality legislation and regulations

More recently oxygenated fuel components have been found to have a beneficial effect on air quality. As public interest in environmental issues has grown, legislators and regulators are seeking various routes to improve air quality. As will be shown later, oxygenates could play a role in lowering automotive emissions. [Pg.8]

EC Directive levels for SO2, NOx and lead have recently been incorporated into UK legislation in the form of the Air Quality Standards Regulations 1989. SO2 is generated when high-sulfur fossil fuels are burned. It is thus a factor of the amount of coal and heavy oil (predominantly) being burned. [Pg.759]

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. [Pg.15]

All air quality-related legislation is based on the presumption of a direct line connecting emissions, ambient air quality, exposure, uptake, dose and effect. Pursuing this idea, regulation starts at the point of emission. Whilst the emissions... [Pg.278]

In most cases legislation and subsequent regulations will determine the ambient concentrations of pollutant to which the receptor is limited. Air quality criteria delineate the effects of air pollution and are scientifically determined dosage-response relationships. The relationships specify the reaction of the receptor or the effects when the receptor is exposed to a particular level of concentration for varying periods of time. Air quality standards are based on air quahty criteria and set forth the concentration for a given averaging time. Thus, the objective for a calculation is to determine if an entission will result in ambient concentrations that meet air quality standards. [Pg.3]

After more than a decade of legislative stalemate, President Bush, the self-proclaimed First Environmentalist , introduced proposals on June 12 1989 to improve US air quality. Under the Bush proposals, sulphur dioxide emissions were to be reduced by 10 million tons by 2000, representing a 50 per cent reduction on 1989 emissions. The proposals also planned to reduce nitrous oxide emissions by 2 million tons. Half of the reductions need to be accomplished by 1995, and the rest by 2000 under the original Bush proposals. Companies would be allowed to decide how to meet compliance levels they could install FGD equipment, bum coal with a low sulphur content, encourage conservation or adopt new clean coal technologies. Those opting for the latter option were allowed until 2003 to comply with the regulations (New York Times. 13 June 1989). These proposals were accepted by the US Senate by 89-11 on April 3 1990, and are virtually certain to become law in some form. [Pg.345]

Environmental exposure to air pollutants is regulated in the United States under authority provided by the Clean Air Act (CAA). The CAA was passed in 1967 and amended in 1970, 1974, 1977, and 1990. A major impetus to federal regulation of air quality was general recognition that many air pollution issues were natural in scope and not just local issues. The CAA is a very comprehensive piece of legislation and a review of it in detail is well beyond the scope of this chapter. Alternatively, this chapter will focus on two key provisions of the CAA as amended in 1990 because they directly involve PM one relates to criteria pollutants and the second to hazardous air pollutants. [Pg.53]

The effect of anthropogenic activity relating to industrial and economic development has had a significant impact on the environment. In recent decades, public awareness of environmental pollution has increased markedly, and the introduction of guidelines and legislation for the protection of water, air and soil quality -of major importance in the political arena - is imminent. As an integral component of environmental policy, it has become essential to regulate and monitor toxic substances. [Pg.403]
