Can more than one type of waste be stored in a satellite accumulation area (SAA)?

Yes, more than one type of waste may be stored in a SAA. The hazardous waste rules do not limit the number of hazardous wastes or the number of containers that may be placed in a SAA; however, the total volume of hazardous waste in a single SAA is limited to 55 gallons, or 1 quart of acute hazardous waste.

Note: The satellite accumulation provisions in the hazardous waste rules allow generators to accumulate up to 55 gallons of hazardous waste or 1 quart of acute hazardous waste in containers at or near any point of generation and under the control of the operator, provided the generator complies with the satellite accumulation requirements in s. NR 662.034(3) or 662.192(4) Wis. Adm. Code.

The satellite accumulation rules require containers to be in good condition, compatible with the waste, stored closed (unless adding or removing waste), and labeled as hazardous waste or with other words identifying the contents.

When the total volume of hazardous waste in the SAA exceeds the limit of 55 gallon or 1 quart of acute hazardous waste, the container must be labeled with the date the excess accumulation was reached. Within three days of that date, the container must be moved to a central hazardous waste storage area.
