| Abstract: | Since passage of the 1977 Amendments to the Clean Air Act, comprehensive transportation planning integrating air quality attainment and maintenance with land use controls has been a major objective. Likewise, economic strategies utilizing the market potential of emission control techniques have come to the forefront as preferable control strategies. Some of these techniques include: 1) emission density zoning in which some pollution is allowed in certain areas while others are kept clean; 2) emission fees whereby cost of emission discharge would be calculated and charged to a source according to a structured market cost benefit; and 3) direct and indirect source review whereby emission increments due to additional or more effective control techniques on one source could be sold to other sources. This technique is known as offsetting emissions or as the emission offset policy. |
