Satellite Accumulation Areas

Satellite accumulation areas are typically located near the area of operation. They allow you to accumulate wastes near the work area where you generate them. However, you must carefully follow the satellite accumulation rules.

Satellite Accumulation Area Limits

Type of Waste

Amount Allowed in Satellite Area

Dangerous Waste

55 gallons

Acutely Hazardous Waste One quart
Extremely Hazardous Waste 55 gallons

Satellite accumulation areas must be under the control of the worker or secured at all times. Containers must be labeled appropriately and remain closed, except when adding waste.

Once a container within your satellite area reaches 55 gallons of dangerous waste, or one quart of acutely hazardous waste, you must mark it immediately with the accumulation start date. You must move the container(s) within three days to a designated storage or accumulation area.
