Permits for Nonmetallic Mining

Mining for nonmetallic minerals (sand, gravel, limestone, granite, etc.) in Wisconsin is regulated by several different programs within the DNR.

Water-Related

There are regulations, requirements and limitations pertaining to the discharge of process wastewater and storm water runoff.  There is a combined general permit for these requirements. A permit fee is authorized under ch. NR 216, Wis. Adm. Code, for stormwater runoff from non-metallic mining operations. If the mine is deemed to be internally-drained, the annual permit fees may not be required.  More Info about the permit...

If the mine is in or near a waterway or wetland, you need a permit to dredge, create a pond or grade in excess of 10,000 feet.  More Info ...

Air Emissions

Waste Management

When the operations cease, there are regulations pertaining to reclamation.

County Regulations

Your county may also have zoning and reclamation requirements.  Note that these are separate and distinct from the DNR requirements.  Satisfying the County does not necessarily take care of your pollutant discharge and streambank protection obligations with the State.
