General VOC rules
There are a range of environmental regulations that affect facilities using solvents in their operations. The following list provides some links to resources for compliance with those regulations.
Air pollution regulations
VOC Emissions Sources and Air Pollution Construction Permits (AM-479) — A fact sheet describing the Air Pollution Construction Permit program and how it affects VOC sources like painting or coating operations or printers; including calculation examples, definitions and contacts for more assistance.
There are a wide range of industries that may use cleaning solvents on their processes, and some of these solvents are required to meet the Industrial Solvent Cleaning Operations RACT Part 1 and 2 (AM-447). Review the fact sheet for more information.
Where no other specific process or pollutant regulations apply to the solvents used at a facility, the general organic compound rule may apply.
Organic compound emissions
The Organic Compound Rule in s. NR 424.03 (AM-478) — Any source with a process line that has organic compound emissions may have to comply with these requirements, and may find this applicable even if they are exempt from an air pollution permit.
- Managing wastes from Spray painting and coating operations (WA–299)
- 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).
- If you reuse solvents, there are important policy issues to understand:
- On-Site Solvent Reclamation: A Guide for Hazardous Waste Generators (WA-1523) [PDF]
- Reusing a hazardous waste in place of a commercial product: Hazardous Waste That is Used or Reused (WA-655)
- Or if you continue to reuse a solvent after the initial use: Hazardous Waste Program Policy on Continued Use (WA-1594)
- Small industrial sources using paints and 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.
