The Division of Mine Permits is responsible for assessing the impact of an applicant’s proposed operation on the environment. A Cumulative Hydrologic Impact Assessment (CHIA) is conducted for each application. The data is organized by the watershed’s Hydrologic Unit Code (HUC), which is used to identify the unique watershed. The data may include surface water quality, benthic information, groundwater quality, water quality violations, pollutant discharge elimination information, mine history and information regarding pending mines.

The files are organized by their HUC 12 watershed and are available for download. There are several ways to obtain the HUC 12 number:

  • Follow "quick links" on the right to utilize maps to obtain the code number. You may also download the data files from the Kentucky Surface Mining Viewer from a hotlink within the DMP HUC 12 table.
    Note: Data Packages will be available for only those watersheds in which mine applications are submitted. A detailed description of the files contained in the Data Packages.

Each Watershed Characterization Data Package contains a Water Quality Results Viewer. This is a forms-driven Microsoft Access application designed to enable the viewer to easily view, filter, sort, graph and export groundwater and surface water quality sample results data.
