Emission density zoning guidebook. A technical guide to maintaining air quality standards through land-use-based emission limits

An emission density zoning (EDZ) regulation is an air pollution control strategy that is similar to traditional land use zoning in that EDZ controls air pollution by setting emission density limits (EDLs) for certain areas of land EDLs restrict the rate of pollutant emission per unit area. The step-by-step procedural guide was designed to help regional planning and air pollution control agencies set EDLs for sulfur dioxide and particulate matter within a metropolitan area. The EDLs, set through the use of a computer-assisted dispersion model and linear programming package, ensure the attainment and maintenance of the national ambient air quality standards and compliance with prevention of significant deterioration regulations.
