Regulatory Resources for Metal Casters

Foundry Sand Regulations

  • MPCA Information: Solid Waste Utilization. The page contains information on the beneficial reuse process.
    • Foundry sand when used as a feed material for the manufacture of Portland cement is considered a Standing Beneficial Use.
  • U.S. EPA Report: Beneficial Reuse of Foundry Sand: A Review of State Practices and Regulations [PDF 293KB]. This report outlines existing state beneficial reuse programs, offers case studies examining reuses of foundry sand, provides a scientific characterization of foundry sands, and suggests approaches to encourage increased future reuse (2002).
  • Organization: AFS-FIRST. AFS-FIRST is an independent non-profit association that is the successor organization to Foundry Industry Recycling States Today (FIRST). The organization exists to educate foundries, end users, government agencies, and other stakeholders about the benefits of using foundry by-products.
  • U.S. EPA Toolkit: State Toolkit for Developing Beneficial Reuse Programs for Foundry Sand [PDF 4.5MB]. This tool is designed to help state’s improve existing beneficial reuse programs or develop a beneficial reuse program that fits a state’s needs.

Other Resources

  • Casting Emissions Reduction Program (CERP). CERP helps the American metal casting industry meet federal clean air standards by testing foundry products and process improvements in a real-world foundry environment, to advance emission measurement capabilities for stationary sources, and to perform research into leading edge energy technologies that could be used to support casting operations.
  • 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.
