This report uses existing data and studies to assess the impact of windblown desert dust on the attainment of TSP standards in major cities situated in desert environments in the Southwestern U.S. Primary emphasis is placed on four cities: Phoenix and Tucson, Arizona; and Las Vegas and Reno, Nevada. It is concluded that: (1) the contribution of windblown dust from the undisturbed desert floor to particulate levels in desert communities is very small and should be considered as part of the background; (2) if human activities repeatedly break up the desert crust, local violations of the 24-hour standards are likely; (3) there is substantial agreement on the principal source categories of fugitive dust contributing to the nonattainment problem and the characteristics of urban areas most affected by each category.
