Small Quantity Generator Self-Certification Program (SQG)

What is an SQG?

That’s the $64,000 question! Most businesses that handle hazardous wastes end up being at least a small quantity generator.

  • You generate 220 lbs or less of hazardous waste in each and every calendar month. That’s about ½ a 55 gallon drum of material!
  • You store more than 220 pounds of hazardous waste under the extended accumulation Adobe Acrobat provisions.

Question: How much is 220 pounds?
Answer: As a rule of thumb, 220 pounds is about ½ a 55 gallon drum.
