How we check it

Every value on this site comes from the official source listed on the page and links back to it.
A listing is published only if it has at least 3 of these attributes populated from the source: Facility type, Off-site receipts (latest Biennial Report), Violation record (5 years), How received waste was managed, Waste received, by EPA code class, Permitted operating units, Final penalties, last 5 years, Formal enforcement actions, last 5 years, Last on-site inspection, Significant noncomplier now.
Each record shows the date we last verified it against the source. Records that disappear from the source are removed at the next refresh.
No text on listing pages is written by hand or generated without data: summaries restate the source fields.

Data last verified: Oct 19, 2026.

Terms you will see

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.
EPA waste codes: D001–D003 are ignitable, corrosive and reactive wastes; D004–D043 fail the toxicity test; F codes are listed wastes from common processes (solvents, plating, dioxins, wood preserving); K codes come from specific industries; P and U codes are discarded commercial chemicals (P acutely hazardous).
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.
Formal enforcement: Legally binding actions (orders, consent agreements, civil or criminal cases), as opposed to informal warning letters.

Fields

EPA ID	EPA RCRA handler identification number.
Operator	Operator named in RCRAInfo.
Owner type	As published by the source.
Permitted operating units	Process types of the facility's current RCRA permit units with an operating legal status.
Off-site receipt flag (RCRAInfo notification)	What the facility last declared on its RCRA notification. Biennial Report receipts show what it actually received, and the two can disagree.
Commercial TSDF	RCRAInfo commercial TSD flag.
Waste received from off-site	Tons of hazardous waste received from off-site in the latest Biennial Report cycle; blank when none was reported.
Waste received, by EPA code class	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. This is what it took in, not a permit limit.
How received waste was managed	Management methods reported for the off-site waste it received in the latest Biennial Report (methods used for at least 2% of tons).
Off-site receipts (latest Biennial Report)	Banded tons of hazardous waste received from off-site.
Biennial Report cycle	As published by the source.
Last on-site inspection	Most recent on-site compliance evaluation by EPA or the state (record reviews excluded).
Inspections, last 5 years	As published by the source.
Violations, last 5 years	Distinct RCRA violations determined in the last five years.
Violation record (5 years)	As published by the source.
Violations not yet returned to compliance	As published by the source.
Violation areas (5 years)	The most frequent RCRA requirement areas cited in violations determined in the last five years.
Formal enforcement actions, last 5 years	As published by the source.
Final penalties, last 5 years	As published by the source.
Significant noncomplier now	RCRAInfo significant-noncomplier (SNC) flag.
Universal waste destination facility	As published by the source.
Used oil activities	As published by the source.
Transfer facility	As published by the source.
Recycler	As published by the source.
Other EPA IDs at this address	Other RCRA handler IDs registered at the same street address, usually by the same operator. RCRAInfo tracks each ID separately (its own permit units, Biennial Report and compliance record), so each has its own page here.
Primary NAICS	Primary NAICS code the facility reported to RCRAInfo (2–6 digits).
Facility type	“Waste management firm” when the primary NAICS code is in waste management and remediation services (562); otherwise an industrial or government site that also holds a TSDF permit. The commercial flag is self-reported, so this is the quicker test of whether outside customers are its business.
