ECAR Fact Sheet for Michigan
Hazardous Wastes

Facilities are required to characterize their wastes to determine if they are hazardous waste, liquid industrial waste, or non hazardous solid waste. Wastes are classified as "hazardous" if they have certain characteristics (for instance, if they are flammable, corrosive, toxic, or reactive) or if the waste chemical or process that produced the waste are listed in the hazardous waste rules.

Hazardous waste generated by auto recycling/salvage yards may include (but are not limited to):

  • Spent solvents
  • Solvent contaminated wipers/shop towels
  • Waste paints
  • Spent fluorescent bulbs (containing mercury)
  • Used antifreeze contaminated with metals, solvents or fuels
  • Used oil contaminated with metals, solvent or fuels
  • Contaminated gasoline
  • Lead acid batteries.
  • Mercury switches

If you are managing the waste as hazardous, here are some of the main requirements:

  • Containers have to be properly labeled, kept closed except when adding and removing waste, and handled to prevent releases. The specific management requirements will depend on how much hazardous waste is generated in a calendar month.
  • You can only store hazardous waste for a limited time on your site before sending it to an approved hazardous waste facility. (The time limit will depend on how much hazardous waste you generate.)
  • If hiring a company, you have to use a permitted and registered waste hauler to transport the waste off your site and keep required records or waste manifests of the shipment
  • Obtain a site identification number (sometimes referred to as an EPA identification number) from the MDEQ Waste and Hazardous Materials Division prior to shipment.
  • Meet recordkeeping requirements. For example, waste characterization records and records of waste shipments must be kept 3 years.

See common violations found by inspectors and use inspection forms as tools when doing a self-audit.
