What is a Large Quantity Generator of Hazardous Waste?

LQGs typically generate 1,000 kilograms (approx. 2,200lbs) of hazardous waste per month or more than 1 kilogram (approx. 2.2lbs) of highly-toxic or acutely toxic hazardous waste per month. There is no limit to the amount of hazardous waste an LQG can accumulate on site, though any accumulated waste must be transported or disposed of within 90 days (some exceptions apply). Biennial hazardous waste reports must be submitted by LQGs in order to maintain compliance. Finally, any LQG operation must designate at least one employee as an acting emergency coordinator in case of emergency, and written contingency plans with detailed response measure must be prepared beforehand and be readily accessible to staff and inspectors.
