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.
Data Packages will be available for only those watersheds in which mine applications are submitted. A detailed description of the files is contained in the Data Packages. The files are organized by their 12-digit HUC watershed code and are available for download. You may obtain the HUC 12 number by viewing a map on KyGovMaps Open Data Portal.
