RCRA TSD Facilities: Permits, Interim Status, and Closure

A RCRA TSD facility permit requires a two-part application under 40 CFR Part 270, compliance with the operating standards in 40 CFR Part 264, proof of financial assurance for closure and long-term care, and a review process that typically runs for years before a permit is issued for a term of up to 10 years. The requirements apply to any facility that treats, stores, or disposes of hazardous waste listed or characterized under the Resource Conservation and Recovery Act of 1976, and the obligations continue for decades after the last shipment of waste is accepted.

When a Permit Is Required

The trigger is the activity, not the industry. Under 40 CFR 260.10, three specific activities pull a facility into the permitting system.¹

Treatment is any process that changes the physical, chemical, or biological character of hazardous waste to neutralize it, reduce its volume, recover material, or make it safer to handle.
Storage means holding hazardous waste temporarily before it moves elsewhere for treatment or disposal. Containers, tanks, and containment buildings count once waste sits past generator accumulation time limits.
Disposal is permanent placement of waste into or onto land or water, most commonly through landfills, injection wells, or surface impoundments.

A single facility can fall into one, two, or all three categories, and the classification drives which specific engineering and operational standards apply. A tank storage yard and a hazardous waste landfill both need permits, but their permit conditions look very different.

Whether to Apply to the State or EPA

Fifty states and territories have been authorized to run their own hazardous waste programs in place of the federal one, so most applicants deal with a state environmental agency rather than EPA directly.² Authorized state programs must be at least as strict as the federal rules and often add requirements on top. Application forms, fees, and review timelines can differ from the federal baseline, so the state agency is the first stop even when the underlying regulatory framework mirrors what is described here.

What Goes Into the Application

Every RCRA permit application has two pieces, Part A and Part B, submitted together or in sequence depending on the agency’s process.³

Part A

Part A is a standardized form covering the identifying facts. It requires the facility’s name, mailing address, and geographic coordinates; owner and operator contact information; SIC codes for the principal business; and a description of the hazardous wastes to be handled along with estimated annual quantities. Applicants also submit a scale drawing showing all past, present, and planned treatment, storage, and disposal areas, photographs of existing structures and waste management areas, and a topographic map extending one mile beyond the property boundary that marks wells, springs, surface water, and nearby drinking water sources.⁴

Part B

Part B is where the engineering work lives. The regulations at 40 CFR 270.14 list more than a dozen required elements, including a chemical and physical analysis of every waste the facility will handle, a complete waste analysis plan, security procedures, a general inspection schedule, and a contingency plan for emergencies.⁵ Applicants must also outline the employee training program, submit a written closure plan (and a post-closure plan for disposal units), and provide current closure cost estimates with documentation of financial assurance.

For units that could affect groundwater, meaning landfills, surface impoundments, and land treatment units, Part B additionally requires hydrogeologic data on groundwater movement beneath the site, the location and design of monitoring wells, and the sampling protocols the facility intends to follow.

Review, Public Comment, and Permit Duration

Once the application package arrives, the agency runs it through two rounds. The first is an administrative completeness check confirming that forms are signed, sections are present, and attachments are included. The second is a technical review of the engineering designs, hydrogeologic data, waste analysis procedures, and financial assurance documentation against the Part 264 standards.

If the application passes technical review, the agency publishes a draft permit and opens a public comment period of at least 45 days.⁶ Community members can submit written comments and request a hearing, and the agency must respond to every significant comment before issuing or denying the final permit. For large or contested facilities, the total timeline can stretch to several years.

Final permits are valid for a fixed term of up to 10 years, and operators that want to keep running must apply for renewal well before expiration through another round of review and public comment.⁷

Interim Status

Facilities that existed before RCRA’s permitting requirements took effect could continue operating under “interim status” if they filed a Part A application and met qualifying conditions under Section 3005(e). Interim status facilities comply with the standards in 40 CFR Part 265, which parallel the Part 264 standards but are somewhat less detailed.⁸ It is not a path available to new applicants, and it is not permanent. Facilities running on interim status should expect their state agency to push toward final permitting or closure.

Operating Requirements Once Permitted

Holding a permit is the starting line. Part 264 obligations are enforced through scheduled and unannounced inspections.⁹

Waste Analysis and Manifests

Every facility needs a written waste analysis plan explaining how it will verify the identity and composition of each incoming shipment before accepting it. When hazardous waste arrives, the receiving facility signs the Uniform Hazardous Waste Manifest and returns a signed copy to the generator confirming the waste reached its destination.¹⁰ Electronic manifests through EPA’s e-Manifest system are increasingly replacing paper. Discrepancies between the shipment and the manifest must be reconciled with the generator or transporter, and unresolved ones reported through e-Manifest.¹¹

Security, Inspections, and Contingency Planning

Unless the operator can demonstrate that unauthorized entry poses no danger, every active waste management area needs either 24-hour surveillance or a physical barrier with controlled entry points. Equipment, containers, and safety systems must be inspected on a fixed schedule. Fire extinguishers, spill control gear, and decontamination supplies must be on site at all times. Each facility also needs a contingency plan detailing response to spills, fires, explosions, or unplanned releases, with a designated emergency coordinator on call at all times who has authority to commit resources immediately. Copies go to the local fire department, police, hospital, and any response team that could be called to the site.

Personnel Training

Every employee involved in hazardous waste management must complete training within six months of starting work or being reassigned, and cannot work unsupervised until it is done.¹² The program must cover emergency procedures, monitoring equipment, alarm systems, and each person’s specific waste-handling duties. Annual refresher training is mandatory, and the facility must keep written training records for every employee.

Biennial Reporting

TSD facilities must file EPA Form 8700-13A/B, the Biennial Hazardous Waste Report, by March 1 of every even-numbered year, covering the previous calendar year.¹³ The report requires the facility’s EPA ID number, the quantities and types of hazardous waste handled, and how it was managed. The next report is due March 1, 2026, covering 2025 activities.

Groundwater Monitoring

Facilities operating landfills, surface impoundments, land treatment units, or certain waste piles must run a groundwater monitoring program targeting the uppermost aquifer beneath the site.¹⁴ Detection monitoring involves upgradient and downgradient wells, at least four samples per well every six months, and statistical comparison of results. The permit specifies which contaminants to test for and which statistical method to use.

If downgradient wells show a statistically significant increase over background, the facility must notify the EPA Regional Administrator within seven days, sample all wells immediately for the broader Appendix IX contaminant list, submit a permit modification application for compliance monitoring within 90 days, and follow with an engineering feasibility plan for corrective action within 180 days.

The Land Disposal Restrictions Limit

Holding a permit does not authorize burying untreated hazardous waste. The Land Disposal Restrictions program under 40 CFR Part 268, added by the 1984 Hazardous and Solid Waste Amendments, prohibits land disposal of hazardous waste until it meets EPA treatment standards, expressed either as concentration limits or as required treatment technologies.¹⁵¹⁶ The category of “land disposal” covers landfills, surface impoundments, waste piles, injection wells, land treatment facilities, salt dome and salt bed formations, underground mines, and concrete vaults intended for permanent disposal. Dilution does not count as treatment.

Financial Assurance

Every TSD owner and operator must demonstrate the financial resources to close the facility properly and, for disposal units, to fund post-closure monitoring for the full required period.¹⁷ The starting point is a detailed written cost estimate in current dollars, calculated as what an independent third party would charge to perform closure, and reflecting the most expensive point in the facility’s active life to shut down.¹⁸ Owners adjust the estimate for inflation annually, either by recalculating or by applying the Implicit Price Deflator published by the Bureau of Economic Analysis.

Several mechanisms can satisfy the requirement:

A trust fund built up over a set pay-in period to the full closure cost estimate.
A surety bond backed by a standby trust fund.
An irrevocable standby letter of credit equal to the cost estimate, backed by a standby trust fund.
An environmental insurance policy with a face value at least equal to the cost estimate, issued by a state-licensed insurer.
A financial test for large companies that can self-guarantee by meeting one of two alternative net worth and asset tests in the regulations.

These instruments are reviewed annually. If financial condition deteriorates or the cost estimate rises, the mechanism must be updated, and losing adequate financial assurance can jeopardize the operating permit.

Corrective Action Reach-Back

A TSD permit can require the facility to clean up contamination it caused. Under RCRA Section 3004(u), any facility seeking or renewing a permit must address releases of hazardous waste or hazardous constituents from all solid waste management units on the property, regardless of when the waste was placed there.¹⁹ That reach extends back to contamination predating RCRA itself. The process generally moves through a RCRA Facility Assessment to identify areas of concern, site characterization to pin down the nature and extent of contamination, and selection and implementation of a remedy, with interim actions available at any stage.²⁰

If contamination has migrated beyond the property line, the owner must pursue off-site corrective action too. The only exception applies when the owner made genuine efforts to obtain access to the neighboring property and was refused, and even then the owner must take every available on-site measure and maintain financial assurance for the full cleanup.

Closure and Post-Closure Care

Every TSD facility must have a written closure plan as part of its permit, describing step by step how waste will be removed or contained and how equipment and structures will be decontaminated.²¹ Closure must begin no later than 30 days after the facility receives its final volume of hazardous waste. The plan is a binding permit condition, and amending it requires regulatory approval. Within 60 days of completing closure, the owner submits a certification signed by both the owner and an independent registered Professional Engineer confirming the site was closed according to the approved plan.²²

For disposal units, closure is only the beginning. Post-closure care runs for 30 years and includes ongoing groundwater monitoring, maintenance of containment systems such as caps and liners, and continued reporting. The Regional Administrator can shorten the period if monitoring shows the site is secure, or extend it if contamination migration suggests otherwise. Financial assurance must remain in place for the entire post-closure period.

Penalty Exposure

Compliance is not optional. Under the inflation adjustment at 40 CFR 19.4, the maximum civil penalty for violations assessed on or after January 2025 reaches $74,943 per day per violation for noncompliance orders under 42 U.S.C. § 6928(c), and up to $124,426 per day for violations of permit conditions or regulatory requirements under § 6928(a).²³ A single inspection that uncovers multiple deficiencies, such as an expired financial assurance instrument, a missed training deadline, and a gap in the inspection log, can generate separate per-day penalties for each. The figures are periodically adjusted upward for inflation.
