Air quality related values (AQRVs) for Greater Yellowstone Network (GRYN) parks: Effects from ozone; visibility reducing particles; and atmospheric deposition of acids, nutrients and toxics

Air quality related values (AQRVs) for Greater Yellowstone Network (GRYN) parks: Effects from ozone; visibility reducing particles; and atmospheric deposition of acids, nutrients and toxics.

This report describes the Air Quality Related Values (AQRVs) of the Greater Yellowstone Network (GRYN). AQRVs are those resources sensitive to air quality and include streams, lakes, soils, vegetation, fish and wildlife, and visibility. The GRYN parks that are included in the NPS Inventory and Monitoring (I&M) Program, and discussed in this report, are Bighorn Canyon National Recreation Area (BICA) and Grand Teton (GRTE) and Yellowstone (YELL) national parks. GRTE and YELL are designated as Class I, giving them a heightened level of protection against harm caused by poor air quality under the Clean Air Act (CAA). Sullivan et al. (2011a, 2011b) and Kohut (2007a) conducted risk assessments for acidification, eutrophication, and ozone (O3) for all of the NCCN parks; their results are described in this report. This report also describes air pollutant emissions and air quality, and their effects on AQRVs. The primary pollutants likely to affect AQRVs include nitrogen (N) and sulfur (S) compounds (nitrate [NO3-], ammonium [NH4+], and sulfate [SO42-]); ground-level ozone (O3); haze-causing particles; and airborne toxics. Background for this section can be found in “Air Quality Related Values (AQRVs) in the Inventory and Monitoring (I&M) National Parks: Status of Visibility Degradation, Ozone Effects on Vegetation, and the Effects on Natural Resources of Atmospheric Acid, Nutrient, and Toxics Deposition” (Sullivan 2016).
