Screening procedure to evaluate air pollution effects in region 1 wilderness areas, 1991. Forest Service general technical report

Based on mandates contained in the 1977 and 1990 Clean Air Act amendments (Public Law 95-95) and the 1964 Wilderness Act (Public Law 88-557), 25 scientists and 15 managers discussed approaches for evaluating air pollution effects on aquatic, terrestrial, and visibility resources in wilderness areas administered by Region 1 of the Forest Service. Participants identified screening parameters that may predictably vary with changes in air quality, Criteria for those parameters were identified for assessing permit applications involving new emissions that may impact wilderness values. Region 1 participation in the multi-agency process for evaluating proposed emissions would require a monitoring program, effective analysis methodology, and proactive review and consultation.
