       This map was developed by SRA International for the U. S. Environmental Protection Agency (EPA). Results are based on site screening criteria
       adapted from National Renewable Energy Laboratory (NREL) criteria and G/S data provided by NREL, EPA and the Virginia Department of
       Mines, Minerals and Energy. This map and its associated data are intended to provide a general understanding of the renewable energy potential
       of orphaned mineral mines in Virginia; additional site specific analysis is required to determine the actual potential of these sites. These sites are
       tracked and monitored by state agencies. For further information, please see the accompanying Data Guidelines document at
