Solvent cleaning operations

There are a range of environmental regulations that affect facilities with solvent cleaning operations. The following list provides some links to resources for compliance with those regulations.

Air pollution regulations

Waste regulations

  • Unused industrial cleaning solvents are often considered hazardous waste. Before disposing of any unused solvent, it is important to review whether the material is hazardous and then properly manage the waste going forward. Start with the SBEAP's hazardous waste page and learn more about hazardous waste management.
  • If you clean up with wipes or rags, be sure to follow the latest procedures outlined in the DNR Waste Program's fact sheet Management of Solvent-Contaminated Wipes (WA-1207) [PDF].

Wastewater regulations

  • Small industrial sources using solvents should check with their local Wastewater Treatment plant or sewerage district about disposal of any industrial materials. They will have limits on what contaminants can be sent to the sewer. You may need to pretreat your wastewater discharge before sending it to the treatment plant. Review the requirements starting on the DNR's wastewater page.
