Hazardous waste generators must calculate the total weight of hazardous waste generated each month to determine their generator category — Very Small Quantity Generator (VSQG), Small Quantity Generator (SQG), or Large Quantity Generator (LQG). This includes any acutely hazardous waste (which must be counted separately) as well as any hazardous waste generated at satellite accumulation areas (SAAs).
This checklist will help you calculate your monthly hazardous waste totals by enumerating what to count — and, just as important, listing what NOT to count when making your monthly assessment.
Calculate your monthly hazardous waste total using the following checklist to note your totals, and then apply these totals to the formula:
Perform your generator calculations on the first day of each month. | Date: | |
Calculate the total weight of all full hazardous waste containers placed into storage (i.e., your central accumulation area (CAA)) during the prior month. Calculate this total weight in pounds or kilograms, and be consistent with your standard of measure throughout. Note: Do not include the weight of the containers themselves! | Total weight placed in CAA for past month:(lbs/kgs) | |
Calculate the total weight of all the waste in satellite accumulation containers in SAAs. | Total weight in SAA accumulation containers:(lbs/kgs) | |
Note the total weight of the waste in satellite containers from the previous month. This weight has already been counted, but may still be present either in satellite containers or in a container since moved to a CAA. | Total weight in SAA accumulation containers from previous month:(lbs/kgs) |
Formula to calculate monthly total (Remember: Acute hazardous waste calculations must be completed separate from nonacute hazardous waste calculations to determine your generator category):
Total weight placed in CAA in past month | lbs/kgs |
PLUS (+) Total weight in SAA accumulation containers | + lbs/kgs |
MINUS (–) Total weight in SAA accumulation containers from previous month | - lbs/kgs |
Monthly hazardous waste total: | lbs/kgs |
