E. Graves D. Santini Department of Economics, University of Chicago Argonne National Laboratory An important area of recent environmental concern is the issue of nonsignificant deterioration of air quality in pristene areas. This paper summarizes and compares current legislative and regulatory agency thinking and notes the relative restrictiveness of three proposed plans dealing with the issue of non-deterioration. Following this exploration into expected legislative directions, the critical analytical questions about which more information is needed are raised. In view of these latter considerations, with particular emphasis on urban-nonurban environmental tradeoffs, it is concluded that the policy issue of deteriorating pristene environments will be with us for many years.
