# Summary of WRAP RMC BART Modeling for Nevada Draft#7 April 24, 2007

Emission Summary: http://pah.cert.ucr.edu/aqm/308/bart/calpuff/emissions/nv_emis_Mar09_2007.xls

This document summarizes the CALMET/CALPUFF BART modeling results performed by the WRAP RMC for Nevada. The procedures used are outlined inthe WRAP RMC BART Modeling Protocol that is available at:
http://pah.cert.ucr.edu/aqm/308/bart/WRAP_RMC_BART_Protocol_Aug15_2006.pdf
The basic assumptions in the WRAP BART CALMET/CALPUFF modeling are as follows:

• Use of three years of modeling of 2001, 2002 and 2003 (except Alaska where just one year, 2002, was used).

• Visibility impacts due to emissions of SO2, NOx and primary PM emissions were calculated (even for Section 309 States):

o Unless States provided speciated PM emissions, all PM emissions were modeled as PM2.5

### .
• Visibility was calculated using the Original IMPROVE equation and Annual Average Natural Conditions.

• CALPUFF Version 6.112 was used.

The tables that follow contain for each Nevada BART source the following information:

• The first row contains the source number, name and SO2 and NOx emissions that were provided by the State.

• Each subsequent row has information on the visibility impacts at Class I area, with the columns containing the following information for the indicated Class I area: 1. The four-letter Class I area identifier; 2. The distance (km) between the source and the closest receptor in the Class I area; 3. The maximum visibility impact in deciview across the three years of modeling; 4. The 99th

### percentile (i.e., 11 th

### highest) visibility impact across the three years of modeling; 5. The 98th

### percentile (i.e., 22th

### highest) visibility impact across the three years of modeling; 6. The number of days the visibility impact at the Class I area exceeded the 0.5 dv threshold; 7. The 98th

### percentile (8th
