The final results are actual public building locations. This is the layer that will be used to identify potential public facilities. As of this report, a request was submitted to Nevada Division of Environmental Protection to determine if it was possible to get a data set with all private and public boilers. NDF has not heard back from NDEP yet. Project areas- This layer was developed based on current ND projects in the Carson Range, Schell Creek Mountains, Virginia City Highlands, Mt. Charleston area and iden- tified projects for Lincoln County through the Ameri- can Recovery and Reinvestment Act (ARRA). The polygons are a general representation of the potential project areas.
