What are the basic requirements for central accumulation areas (on-site storage) for hazardous waste?

• A. Use compatible, closed containers; label with contents and accumulation start date; maintain secondary containment as needed; and comply with generator category time limits.
• B. Keep containers open and unlabeled.
• C. No secondary containment is required.
• D. Labeling is optional.

Answer: (A)

Central accumulation areas require careful controls to prevent releases and keep on-site storage under control. The waste must be kept in compatible, closed containers so reactions and leaks are minimized; containers should only be opened for adding or removing waste. Each container needs a label showing what the waste is and the accumulation start date, so you can track how long it has been stored and what it is. Secondary containment is required to catch leaks or spills, sized to hold the contents of the largest container (and in line with regulatory sizing rules) so a spill doesn’t escape the area. Finally, you must manage the waste within the generator category time limits, meaning you transfer or treat it within the regulatory window applicable to your generator status. Open or unlabeled containers, no secondary containment, or labeling that isn’t required would not meet these requirements.
