The purpose of the study was to determine the nature and extent of air pollution in the Lewiston-Clarkston area and to assemble information to be used as a basis for technical and official action needed to conserve air quality in the area. Because of its unique valley location, the two-city area is susceptible to meteorological conditions conductive to pollutant accumulation. Either city contaminate the other, and this creates a multijurisdictional problem that requires joint and cooperative action to control air pollution. As a first step to solve the problem, an Air Resources Management Council consisting of county, city and state officials is to be organized. This council will be responsible for planning surveys and studies to determine air quality guides and legislation and administration necessary to control air pollution in this multijurisdictional area. The Public Health Service in its advisory capacity will provide technical assistance. (Author)
