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 in the 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., 11th 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 highest) visibility impacts in 2001;

8. The 98th percentile (8th highest) visibility impacts in 2002;

9. The 98th percentile (8th highest) visibility impacts in 2003;

10. The average of the 98th percentile across 2001, 2002 and 2003
