The DNR Nonmetallic Mining Program works to ensure local and county governments and mine operators across the state follow standards for mine reclamation, and provides assistance in developing mine reclamation plans and using a variety of materials in reclamation. The DNR's Air and Water programs also work with nonmetallic mining operations to issue permits and ensure the mining sites are complying with state wastewater, storm water runoff and air emissions standards.
Counties and local governments have responsibility for siting nonmetallic mines through existing zoning processes and for regulating mine operation. The DNR is not involved in the mine siting process and does not maintain a comprehensive list of current nonmetallic mines in the state.
Stormwater runoff is rainfall that flows over the ground surface. It is created when rain falls on roads, driveways, parking lots, rooftops and other paved surfaces that do not allow water to soak into the ground. Stormwater runoff is the number one cause of stream impairment in urban areas.

The goal of animal waste management is to make best use of the nutrients in manure while protecting natural resources. When managed properly, manure can be a valuable resource on a farm. It can be a source of nutrients for crop production and can improve soil quality. However, if there is insufficient land to use the amount of manure that is produced or if manure is mismanaged, then risks to water supplies and the environment could result.

Manure irrigation is the process of applying liquid manure (effluent) to cropland through sprinkler irrigation. Because effluent is primarily water with a very small percentage of solids, it can be applied with sprinklers, such as traveling guns or center pivots. With pivots, special consideration must be taken to prevent clogging of sprinklers with the solids. Traveling guns have larger sprinklers, so they can accommodate up to approximately 5 percent solids whereas center pivots can only handle about 3 percent solids.
