Regulatory Information for Metal Casters

Foundry Sand Regulations


Emissions Resources

The National Emission Standards for Hazardous Air Pollutants (NESHAPs) include major sources and area sources. The MPCA incorporates major source standards into facility permits and enforces the requirements. The Environmental Protection Agency enforces the area source standards. NESHAPs are an additional federal standard beyond an air permit. The MPCA Small Business Environmental Assistance Program (SBEAP) can help most metal casters in Minnesota understand their requirements under these rules.

Waste Resources

In the seven county Twin Cities metro area, the counties have authorization to manage hazardous waste through county ordinances. Outside the metro, the MPCA has jurisdiction.
