Active Coal Mine Permit Areas
The information below shows the active coal mine permit areas in Wyoming, and the mine name and the LQD mining permit number are associated with this information.
Coal mine permit areas are dynamic and change frequently in response to mining needs. Therefore, please note that this information is updated approximately twice each year, so changes that have occurred since the last update are not reflected in this information.
For more detailed information, please refer to the individual permit of the coal mine site that you are hoping to gain more information about.
