Hazardous Waste Generator Requirements 401

FIGURE 12.1 (Continued)

liquid hazardous wastes containing polychlorinated biphenyls (PCBs). The requirements for the
management of PCBs appear in 40 CFR Part 761.
Both LQGs and SQGs must accumulate waste in tanks or containers. The U.S. EPA defines
“container” as:
Any portable device in which a material is stored, transported, treated, disposed of, or otherwise handled.

The most common example of a container is a 55 gal drum. A “tank” is defined as:
A stationary device, designed to contain an accumulation of hazardous waste constructed primarily of
nonearthen materials (e.g., wood, concrete, steel, and plastic), which provide structural support.

Storage tanks and containers must be managed according to EPA requirements summarized
below. Each container holding hazardous waste must:

● Be labeled with the words “Hazardous Waste.”
● Be marked with the date the waste was first generated.
