Mining Permit Viewer - for mine sites closed prior to 2016*
Mining Permit Viewer interactive map shows mine site locations and information, including downloadable permit files. The permit data and files available were compiled from the hard copy permit held by the Oregon Department of Geology and Mineral Industries (DOGAMI) Mineral Land Regulation and Reclamation (MLRR) program.
*Please note that the information currently available through the Mining Permit Viewer is for surface mine sites that were closed prior to 2016. The Mining Permit Viewer does not have information regarding currently open mine sites.
Currently the map shows permit data for the following counties. Data for other counties will be added as resources allow.
Types of Permit & Data Files
The information contained in the PDF downloads has been collected over the life of the mine site beginning as early as July 1, 1972 and ending with the latest data. Each mine site may have many records available for download. Please note: Files that exist only in the electronic version of the permit are not available for download. Data have not been reviewed for completeness or accuracy.
There are three types of records; the suffix in the document title and the description help identify what files are available.
"LS" - "Left Side - Permits and Inspection" -
These records are from the left side of the physical mining file and contain information regarding issued permits and inspections.
"RS" - "Right Side - Permit Info and Communications" -
These records are from the right side of the physical mining file and contain information regarding the permit; such as the site plan, reclamation plan, and coordination between DOGAMI and the permittee or other agencies.
Water Quality Files
"WQLS" - "Left Side - Permits, Inspections, Renewals, Compliance" -
These records are from the left side of the physical water quality file and contain information regarding the permit, inspections, renewals, and compliance.
