Do I Qualify?

 

If you produce 220 pounds or 27 gallons or less of hazardous waste in any month you qualify for this program.

If you produce more than this quantity, you are considered a large quantity generator and must contact a hazardous waste transporter  for proper handling, transport and disposal of your hazardous waste.

5 Gallon Size Container Limit - We can only accept containers that are up to 5 gallons in size. If you current container size is too large, follow these tips:

  • Get containers that are 5-gallons in size, such as a paint bucket with a lid.
  • Transfer waste from your larger container into the smaller one. Use as many smaller containers as needed.
