Protection of air quality values is a key component of both the Clean Air Act and Wilderness Act. The USFS Region 1 has 13 designated Wilderness areas. In terms of air quality, seven are designated as Class I Wilderness areas and six are designated as Class II Wilderness Areas. Class l areas in USFS R1 were designated by the Clean Air Act amendments of 1977. The 1977 Clean Air Act amendments assigned the Forest Service an “affirmative responsibility” to protect the Air Quality Related Values (AQRV’s) of Class l areas. Class II areas include all other areas of the country that are not Class I. Class II Wilderness areas are Class II for the Clean Air Act Prevention of Significant Deterioration (PSD) regulations. Air quality protection authority (beyond ambient air quality standards and PSD increments) for Class II Wilderness areas therefore relies primarily upon the Wilderness Act with the air quality values titled Wilderness Air Quality Values (WAQV’s).
Region 1 has been actively monitoring AQRVs and WAQVs since 1989. Formal AQRV monitoring plans for regional Class I Wilderness areas were developed between 1989 and 1996. For Class II Wilderness areas, formal WAQV plans were developed in 2007 and 2008 in accordance with the 10-Year Wilderness Challenge. The following table summarizes the plan development for each Wilderness area; each plan is referenced at the end of this plan and tabulated below.
