Small Quantity Generator Waste Code Register

PROBLEM: In EPA Docket RCRA-03-2026-0061, Columbia Woodworking (Washington, DC) notified regulators it was a small quantity generator (RCRA ID DCD983971201) and was inspected May 21–22 and May 28, 2025; EPA found Subtitle C violations for lacquer thinner and paints carrying EPA hazardous-waste codes D001, D009, D035, F003 and F005. Small generators are common — woodshops, printers, auto shops — and the waste codes are what decide how the waste must be handled.

SOLUTION: An IBM Cloud Ideas compliance improvement that maintains a small-quantity-generator waste-code register: each waste stream is recorded with its EPA codes, generator category and accumulation start date, and any stream missing a code, or any accumulation past its limit, is flagged for the shop owner in plain language.

EVIDENCE BASIS: DOCUMENTED — EPA Expedited Settlement Agreement, Docket RCRA-03-2026-0061 (May 28, 2026): Columbia Woodworking, Washington, DC; small quantity generator; inspected May 21–22 and 28, 2025; lacquer thinner and paints, codes D001, D009, D035, F003, F005.
