Key facts

Facility type	Industrial site receiving off-site waste “Waste management firm” when the primary NAICS code is in waste management and remediation services (562); “industrial site receiving off-site waste” when another industry's site records waste received from off-site in its latest Biennial Report; otherwise an industrial or government site that also holds a TSDF permit. A NAICS code is classification evidence, not proof of whether a facility takes outside business. source, unchanged since Oct 20, 2026
Off-site receipts (latest Biennial Report)	Under 1,000 tons in 2023 Banded tons of hazardous waste received from off-site, with the Biennial Report year (EPA publishes each cycle about two years after it ends). source, unchanged since Oct 19, 2026
Violation record (5 years)	6–20 violations Violations determined in the last five years, banded. A facility with none can still have formal enforcement or penalties in those years for violations determined earlier; its band says so. source, unchanged since Oct 19, 2026
How received waste was managed	Storage and transfer Management methods reported for the off-site waste it received in the latest Biennial Report (methods used for at least 2% of tons). source, unchanged since Oct 19, 2026
Waste received, by EPA code class	Toxic organics (D012–D043), Spent solvents (F001–F005), Ignitable waste (D001) Main EPA waste-code classes on the off-site waste it reported receiving in the latest Biennial Report: classes with at least 5% of tons received, each waste line's tons split evenly across the classes on it.

TSDF: A facility permitted under RCRA to treat, store or dispose of hazardous waste.

Significant noncomplier: EPA's designation for facilities with serious or chronic RCRA violations. The regulator sets and lifts it, so it can stay on while an enforcement case or compliance schedule is open, even after the individual violations are marked as returned to compliance.

Biennial Report: The national report every two years of hazardous waste generated, managed, shipped and received; tons received are the latest cycle EPA has published.

Off-site receipt flag: What the facility last declared on its RCRA notification form. Facilities re-notify only when something changes, so the flag can be out of date: a facility flagged “No” can still report tons received from off-site in the Biennial Report, which records what it actually received. Where they disagree, the Biennial Report tons are the better evidence.

Formal enforcement: Legally binding actions (orders, consent agreements, civil or criminal cases), as opposed to informal warning letters.
