Dear Ms. McKaughan: 

Enclosed please find information pursuant to your request for more information to help 

you make a decision and take final action as to the Nevada Division of Environmental 

Protection's ("NDEP") determination of BART at the Reid Gardner Generating Station 

("Reid Gardner"). Your initial request dated December 23,2011, listed a significant 

amount of information that you considered to be important for your deliberations. Based 

on our subsequent teleconference, you narrowed that list substantially to vendor 

information supporting costs for the technologies that were considered for BART and to 

the model input files. 

Per our discussions with you on January 25, 2012, we are providing the following: 

1.	 The modeling files that have been made available to NDEP by CH2M Hill, 

which performed the analysis utilized by NvEnergy for Reid Gardner; 

2.	 Graphs of the cost analyses that include the values that EPA developed for the 

technologies under evaluation as compared to the values that NDEP used, 

which shows that the comparison of the incremental cost does not change 

even when EPA's values are substituted 

We apologize for not being able to get this information to you by February 3, 2012. We 

were initially focused on trying to get a realistic estimate of the time and cost that would 

be required to respond to your initial list. After our teleconference on January 11,2012, 

during which you substantially narrowed the request, and per our conversation on 

January 25, 2012, we focused on obtaining the model input files, which took quite some 

time to copy. 

Please do not hesitate to contact me if you have any questions.
