Section 1 

Arizona Class I Area Visibility Impairment Analysis 

The figures presented in this appendix provide a representation of the potential transport of visibility 

impairing pollutants at Class I areas in Arizona. The Weighted Emissions Potential (WEP) is a tool that 

shows the predominant emission sources that potentially contribute to haze. The maps are broken down 

by pollutant and show the potential contribution for 20% worst visibility days for the baseline period and 

projected 2018 emissions. Each map has a 100 kilometer and 200 kilometer radius circle around each 

Class I area and the shaded colors represent areas that potentially contribute to visibility impairment at the 

Class I area. The pollutants covered are sulfur dioxide (SO2), nitrogen oxides (NOx), organic carbon 

(OC), elemental carbon (EC), coarse mass (CM), fine soil (FS), ammonia (NH3), and volatile organic 

compounds (VOCs).

Visibility Impairment Analysis 

Contribution to Class I Areas in Colorado, Utah, and New Mexico 

The tables in this section represent the percent contribution to sulfate and nitrate at Class I areas in 

Colorado, New Mexico, and Utah. The data is from the PSAT modeling analysis for the 2002 base case 

(plan 02c) and 2018 projections (base 18b). The tables show the highest contributors only, not all 

contributions from all states or regions. The tables also provide the concentrations from point, area, 

mobile, natural fire/biogenic, and anthropogenic fire. The tables do not provide the total concentration for 

each Class I area. 

Colorado Class I areas: 

 Mesa Verde National Park (MEVE1) 

 Black Canyon of the Gunnison National Park, La Garita Wilderness, and Weminuche Wilderness 

(WEMI1) 

 Great Sand Dunes National Monument (GRSA1) 

 Eagles Nest Wilderness, Flat Tops Wilderness, Maroon Bells-Snowmass Wilderness, and West 

Elk Wilderness (WHRI1) 

New Mexico Class I areas: 

 Gila Wilderness, New Mexico (GICL1) 

 Bosque del Apache National Wildlife Refuge, New Mexico (BOAP1) 

 San Pedro Parks Wilderness, New Mexico (SAPE1) 

 Bandelier National Monument, New Mexico (BAND1) 

Utah Class I areas: 

 Zion National Park (ZION1) 

 Bryce Canyon National Park (BRCA1) 

 Capitol Reef National Park (CAPI1) 

 Canyonlands National Park and Arches National Park (CANY1)
