Due to a lack of communication between urban, regional, and transportation planning agencies and air pollution control agencies, cooperative efforts in environmental planning have been nearly non-existent. This traditional lack of communication and understanding serves to obscure the fact that air pollution control agencies and planning agencies in the final analysis have similar goals and can profit from each other's knowledge, expertise, and activities. Differences, however, are usually evident in their scope of activity; planners often think of themselves as generalists, expert only in a process while pollution control individuals are viewed as specialists, defining a situation and controlling it. Papers in this volume are thus directed toward this problem and its components, with particular emphasis on land use planning and air quality management. Part I, Establishing the Relationship, identifies transportation and land use elements in air quality implementation plans, management programs, and state level planning situations. Part II, Transportation and Air Pollution, explores existing problems and possible strategies for solution. Part III, Procedures for the Urban Planner, surveys land use planning tools, the impact of urban growth and development, locating pollution sources, and industrial performance standards all in relation to air quality standards and management. Bibliographic references, charts, and diagrams are included. (BL)
