EPA estimates that about 80 percent of the 100 million registered motor vehicles exceed Federal emission standards. About half the cars pass beyond acceptable emission limits within a year of manufacture, with the rate steadily increasing thereafter. Poor owner maintenance and infrequent inspections account for most of this figure. According to EPA, these failures are due to maladjusted engine settings, premature parts failure, use of leaded fuels, improper car use, tampering with emission control systems, and poor design or production practices. Mandatory annual inspection and maintenance programs can identify and correct many of these problems, but a short test is needed to check compliance. EPA claims to have such a test available, but manufacturers question its applicability. The Clean Air Act requires inspection and maintenance programs in areas where car emissions contribute significantly to air pollution; EPA has identified 110 of these areas, but only 6 currently have such programs. Other enforcement efforts are also below par, including assessment of emissions performance at all stages of vehicle life: design, production, and use. The EPA prototype certification program overlooks the deterioration of engine system components, among other factors.

State and Federal Standards for Mobile-Source Emissions available in PDF, EPUB and Kindle. Emissions from mobile sources contribute significantly to air pollution in the United States. Such sources include cars and light- and heavy-duty trucks; diesel-powered cranes, bulldozers, and tractors; and equipment such as lawnmowers that run on small gasoline engines. The role of state versus federal government in establishing mobile-source emissions standards is an important environmental management issue. With this in mind, Congress called on EPA to arrange an independent study of the practices and procedures by which California develops separate emissions standards from the federal government and other states choose to adopt the California standards. The report provides an assessment of the scientific and technical procedures used by states to develop or adopt different emissions standards and a comparison of those policies and practices with those used by EPA. It also considers the impacts of state emissions standards on various factors including compliance costs and emissions. The report concludes that, despite the substantial progress in reducing emissions from mobile sources nationwide, more needs to be done to attain federal air-quality standards in many parts of the country. Additionally, California should continue its pioneering role in setting emissions standards for cars, trucks, and off-road equipment.
