RCRA & Solid/Hazardous Waste Management

The United States generates approximately 290 million tons of municipal solid waste per year, plus a vast and less precisely measured volume of industrial and hazardous waste. The Resource Conservation and Recovery Act (RCRA, 1976) (42 U.S.C. §§ 6901–6992k) is the federal framework for managing that waste — from the moment it's generated to its final disposal — built around a "cradle-to-grave" tracking and accountability system. RCRA operates through three major programs: Subtitle C (hazardous waste) imposes strict requirements on approximately 700,000+ generators and 2,000+ treatment, storage, and disposal facilities (TSDFs), requiring permits, manifests, and stringent standards for every stage of hazardous waste handling; Subtitle D (solid waste) sets federal criteria for municipal solid waste landfills, where roughly 50% of the nation's solid waste is buried; and Subtitle I (underground storage tanks) regulates approximately 540,000 active petroleum and chemical storage tanks and has driven cleanup of over 590,000 historical leaks. EPA and authorized state agencies jointly enforce RCRA. Civil penalties reach $70,117/day per violation; criminal conviction for knowing endangerment carries up to 15 years imprisonment.

Current Law (2026)

Legal Authority

• 42 U.S.C. § 6901 — Congressional findings (improper waste management creates health hazards and environmental problems; the generation of hazardous waste should be reduced; land disposal should be the least favored method)
• 42 U.S.C. § 6921-6939g — Subtitle C: Hazardous waste management (identification and listing of hazardous waste; standards for generators, transporters, and TSDFs; permit requirements; "cradle-to-grave" tracking; corrective action for contamination)
• 42 U.S.C. § 6941-6949a — Subtitle D: Solid waste (federal guidelines for solid waste management plans; criteria for sanitary landfills; prohibition of open dumping; state/local implementation; recycling and waste minimization)
• 42 U.S.C. § 6991-6991m — Subtitle I: Underground storage tanks (regulation of USTs containing petroleum or hazardous substances; leak detection, prevention, and corrective action; UST trust fund for cleanup; owner/operator financial responsibility)
• 42 U.S.C. § 6928 — Federal enforcement (compliance orders; civil penalties up to $70,117/day per violation; criminal penalties for knowing violations — up to $50,000/day and 2-15 years imprisonment)
• 42 U.S.C. § 6926 — Authorized state programs (states may receive authorization to administer the hazardous waste program in lieu of federal EPA; ~48 states are authorized)

Implementing Regulations (40 CFR Parts 239-282)

Subtitle D — Solid Waste Guidelines:

• 40 CFR Part 246 — Source Separation for Materials Recovery Guidelines (RCRA Subtitle G federal recycling guidelines implementing 42 U.S.C. § 6907 — the statutory authorization for EPA to publish guidelines for solid waste collection, source separation, and recovery of materials from solid waste; the guidelines are not mandates for private entities but establish federal government requirements and guidance for state and local programs):

  • § 246.200 — High-grade paper: office facilities with more than 100 office workers must separate high-grade paper (white bond, computer printout, letterhead) at the source, collect it separately, and sell it for recycling; this is the only binding requirement in Part 246 — it applies to federal agencies and federal contractors with large office operations; facilities with fewer than 100 workers are covered by recommended (not required) practices in §§ 246.200-2 through 246.200-10, including market studies, employee education programs, and collection container placement standards
  • § 246.300 — Corrugated cardboard: guidelines for separate collection and marketing of corrugated cardboard from institutional and commercial generators; recommended practices cover baler selection, storage area requirements, market identification, and transportation; corrugated is the highest-volume recyclable material by weight in commercial solid waste — large retail stores, warehouses, and food service facilities generate significant cardboard volumes that are highly marketable to recycled-content paperboard mills
  • § 246.400 — Glass: guidelines for source separation of container glass (bottles, jars) from residential, institutional, and commercial generators; covers color-separated collection (clear, brown, green) to maximize value to glass manufacturers; glass contamination with ceramics, Pyrex, or window glass degrades the cullet and reduces value
  • § 246.500 — Metals: guidelines for source separation of ferrous metals (steel cans, appliances) and non-ferrous metals (aluminum cans, copper pipe); magnetic separation is the primary ferrous recovery mechanism; aluminum beverage container recycling has one of the highest value-per-ton economics of any recycled material — Part 246's aluminum guidance helped establish the industry norm of separate aluminum can collection

  The Part 246 guidelines were promulgated under RCRA's Subtitle G (42 U.S.C. § 6907) as part of the 1976 RCRA framework, making them among the earliest federal recycling directives. While the guidelines themselves are primarily advisory, they established the framework that most state recycling programs built upon. The mandatory paper recycling requirement for large federal office facilities (§ 246.200) was part of EPA's effort to lead by example — federal agencies were among the largest office paper consumers in the 1970s when the rule was issued. Today, Executive Order 14057 (2021 federal sustainability EO) and GSA procurement requirements impose broader federal sustainability obligations that subsume the Part 246 paper recycling mandate, but the regulatory text remains in force as independent authority.

Subtitle C — Hazardous Waste:

• 40 CFR Part 260 — Hazardous waste management system: general definitions, petitions, and procedures

• 40 CFR Part 261 — Identification and Listing of Hazardous Waste: the foundational RCRA regulation that defines what is (and isn't) legally "hazardous waste" — the regulatory universe that triggers all downstream RCRA requirements. Part 261 operates through two parallel tracks:

  • Subpart C — Characteristics (§§ 261.21–261.24): a waste is hazardous by characteristic if it exhibits one of four properties — ignitability (flash point below 60°C, or capable of causing fire through friction/absorption/spontaneous chemical changes); corrosivity (pH ≤2 or ≥12.5, or corrodes steel at >6.35 mm/year); reactivity (unstable, reacts violently with water, generates toxic gases, or is capable of detonation); or toxicity (measured by the Toxicity Characteristic Leaching Procedure (TCLP) — a lab test that simulates leaching in a landfill; wastes leaching heavy metals, pesticides, or solvents above regulatory thresholds are D-code hazardous wastes)
  • Subpart D — Listed Wastes (§§ 261.30–261.39): EPA has independently listed specific wastes that are hazardous by regulatory decision rather than by characteristic testing: F-list wastes (spent solvents, sludges, and process residues from common industrial operations — e.g., F001/F002 spent halogenated solvents); K-list wastes (specific wastes from particular industrial processes — petroleum refining, wood preservation, organic chemical manufacturing); P-list and U-list wastes (unused commercial chemical products that are acute hazardous or toxic — e.g., arsenic, cyanides, and certain pesticides when discarded unused); listed wastes are hazardous regardless of actual concentrations
  • Subpart E — Exclusions/Exemptions (§§ 261.4–261.6): important exclusions from RCRA Subtitle C regulation include household hazardous waste, agricultural wastes returned to the soil, mining overburden, Bevill exemptions (certain high-volume utility wastes), and wastes from crude oil and natural gas exploration
  • The "mixture rule": any mixture of a listed hazardous waste with any other solid waste is itself a listed hazardous waste — preventing disposal facilities from diluting listed waste to escape regulation
  • The "derived-from rule": any solid waste derived from treating, storing, or disposing of a listed hazardous waste (e.g., incinerator ash, treatment sludge) is itself a listed hazardous waste — closing the loop-hole of treating away hazardous character

  Part 261's air emission subparts (Subparts AA, BB, CC) address a separate but related issue: air emissions from hazardous secondary materials stored in tanks, containers, and surface impoundments at facilities excluded from full RCRA Subtitle C regulation. These subparts establish process vent standards (§§ 261.1030–261.1035) and equipment leak standards (§§ 261.1050–261.1085) for facilities storing excluded hazardous secondary materials that may reuse or reclaim them.

• 40 CFR Part 262 — Standards Applicable to Generators of Hazardous Waste (66 sections — the foundational compliance rules for the ~700,000 entities that generate hazardous waste in the U.S.; who must comply, which rules apply, and what the generator must do before waste leaves the facility). Key provisions:

  • § 262.11 — Hazardous waste determination and recordkeeping: any person who generates a solid waste must determine whether it is hazardous using the Part 261 identification system (listed waste or characteristic waste); this determination must be made at the point of generation and the records kept for 3 years; skipping the determination step is itself a violation
  • § 262.13 — Generator category determination: a generator's regulatory tier is based on the total quantity of hazardous waste generated in a calendar month — Very Small Quantity Generator (VSQG): generates ≤100 kg/month of hazardous waste and ≤1 kg/month of acutely hazardous waste; Small Quantity Generator (SQG): generates >100 kg but ≤1,000 kg/month; Large Quantity Generator (LQG): generates ≥1,000 kg/month or ≥1 kg/month of acutely hazardous waste; a single high-volume month bumps the generator to a higher tier for that month
  • § 262.14 — VSQG conditions: VSQGs are not required to obtain EPA ID numbers or use a manifest, but must still ensure waste is sent to a proper disposal facility (RCRA-permitted TSDF, recycler, universal waste handler, or another VSQG facility that sends waste to a compliant facility); VSQGs have no time limit for on-site accumulation but must never mix VSQG hazardous waste with other hazardous waste unless consolidating under proper conditions
  • § 262.15 — Satellite accumulation areas: all SQGs and LQGs may accumulate hazardous waste at or near the point of generation in satellite accumulation areas — limited to 55 gallons per waste stream (1 quart for acutely hazardous waste); no permit or time limit required for satellite areas; once the 55-gallon limit is reached, waste must move to the generator's main accumulation area within 3 days; satellite areas do not require EPA ID numbers
  • § 262.16 — SQG accumulation conditions: SQGs may accumulate hazardous waste on-site for up to 180 days (270 days if the nearest permitted TSDF is more than 200 miles away); must label containers with "Hazardous Waste," the hazard, and the accumulation start date; storage areas must meet Part 265 standards (secondary containment, aisle space, emergency equipment); SQGs must have a contingency plan and emergency coordinator; employee training is required
  • § 262.17 — LQG accumulation conditions: LQGs may store on-site for up to 90 days before shipping to a TSDF; storage must meet full Part 264/265 standards; LQGs must have a comprehensive written contingency plan coordinated with local emergency responders; a 24-hour emergency coordinator must be designated and reachable at all times; annual training for all hazardous waste management personnel; quarterly inspections of storage areas
  • § 262.18 — EPA identification numbers: SQGs and LQGs must obtain an EPA ID number before generating, transporting, treating, storing, or disposing of hazardous waste; obtained by submitting EPA Form 8700-12 (the Site Identification Form) to the state RCRA agency; ID numbers are facility-specific and follow the facility through ownership changes
  • § 262.20 — Uniform Hazardous Waste Manifest: SQGs and LQGs must use the Uniform Hazardous Waste Manifest for every off-site hazardous waste shipment; the manifest tracks the waste from generator to TSDF; generators must keep signed copies for 3 years; if the signed manifest copy is not returned by the TSDF within 35 days (60 days for LQG), the generator must investigate and file an exception report with EPA
  • §§ 262.200–262.213 — Optional alternative standards for academic laboratories: colleges, universities, and teaching hospitals that qualify as LQGs or SQGs may opt into an alternative regulatory framework for managing lab chemicals as "unwanted materials" rather than conventional hazardous waste; academic labs typically generate many different waste streams in small quantities; the lab standards allow consolidation and characterization at a central accumulation area rather than requiring per-waste-stream satellite containers

  The Generator Improvements Rule (81 FR 85820, November 28, 2016) substantially revised Part 262, restructuring the VSQG provisions (formerly "conditionally exempt small quantity generators"), clarifying satellite accumulation area requirements, and adding an option for VSQGs to consolidate waste at LQG facilities under the same organizational structure. 88 FR 54111 (August 2023) made additional updates to manifest and reporting requirements. Part 262's generator tier system means compliance costs and obligations can shift dramatically based on generation rate — a facility that exceeds 1,000 kg in a single month faces full LQG requirements for that month, including the 90-day accumulation clock, even if it's normally a VSQG.

• 40 CFR Part 263 — Standards for Transporters of Hazardous Waste: the regulatory requirements for companies and individuals that transport hazardous waste between generator facilities and treatment, storage, or disposal facilities (TSDFs). Applies whenever the waste requires a manifest under Part 262. Key provisions:

  • § 263.11 — EPA identification number: a transporter may not move hazardous waste without first obtaining an EPA ID number using Form 8700-12; this creates a registry of all entities in the hazardous waste transport chain, enabling EPA and states to track violations and identify unregistered illegal haulers
  • § 263.20–263.22 — Manifest compliance: a transporter may not accept hazardous waste from a generator unless provided with a signed manifest (EPA Form 8700-22 or electronic equivalent); the transporter must sign and date the manifest, give a copy to the generator, carry the manifest during transport, and deliver the entire quantity to the designated TSDF; upon delivery, the TSDF signs the manifest — this chain of signatures creates the "cradle-to-grave" paper trail from generation through disposal
  • § 263.12 — Transfer facility storage: a transporter may store manifested hazardous waste in properly marked containers at a transfer facility for up to 10 days without triggering TSDF permit requirements; storage beyond 10 days requires a RCRA storage permit (Parts 264/265); this rule accommodates the practical need for short-duration terminal storage without burdening every transfer point with full TSDF permitting
  • § 263.30–263.31 — Discharge response: if a hazardous waste discharge occurs during transport, the transporter must take immediate action to protect human health and the environment (notify the National Response Center and state authorities if required, contain the discharge, and clean up any released waste); the transporter becomes a "generator" of any residual waste from the cleanup

  Part 263 is the middle link in RCRA's cradle-to-grave chain: generators create and manifest the waste (Part 262), transporters move it on the manifest (Part 263), and TSDFs receive and manage it (Parts 264/265). The manifest system means that any hazardous waste shipment produces a document trail that regulators can audit — a generator whose manifest is never signed by the destination TSDF knows something went wrong. The DOT hazardous materials regulations (49 CFR Parts 171–180) apply simultaneously during transport, covering packaging, labeling, placarding, and driver training; RCRA Part 263 and DOT hazmat requirements are complementary but distinct.

• 40 CFR Part 264 — Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities (207 sections — the operational and engineering standards every permitted TSDF must meet; applies to landfills, surface impoundments, waste piles, land treatment units, incinerators, tank systems, container storage areas, and drip pads):

  • Subpart B — General Facility Standards (§§ 264.10–264.19): waste analysis plans (characterize each waste before treating, storing, or disposing); security (24-hour surveillance or physical barriers); inspections (written schedule, records); emergency equipment; training of TSDF personnel (basic + operational + emergency procedures)
  • Subpart C — Preparedness and Prevention (7s): emergency response equipment (portable fire extinguishers, spill control, decontamination equipment); internal communications; coordination with local emergency response agencies; aisle space for emergency equipment access
  • Subpart D — Contingency Plan and Emergency Procedures (7s): written contingency plan updated when facility, operations, or emergency contacts change; emergency coordinator available 24/7; all emergency response procedures for releases, fires, explosions; notification of NRC and state/local authorities for releases exceeding reportable quantities
  • Subpart E — Manifest System, Recordkeeping, and Reporting (8s): TSDFs must verify manifests match shipments; sign and return manifests to generators within 30 days; biennial reports to EPA on waste quantities and management methods; unmanifested waste report within 15 days
  • Subpart F — Releases From Solid Waste Management Units (12s): corrective action for releases from any solid waste management unit at a permitted facility, regardless of when wastes were placed — the basis for RCRA Corrective Action program at 3,700+ facilities nationwide
  • Subpart G — Closure and Post-Closure (11s): written closure plan; closure must be completed within 180 days; post-closure care period of 30 years for containment units; EPA may shorten or lengthen 30-year period based on site conditions; post-closure permit required for land disposal units
  • Subpart H — Financial Requirements (12s): closure cost estimate; post-closure cost estimate; financial assurance mechanisms (trust fund, surety bond, letter of credit, insurance, or financial test/guarantee); liability coverage ($1 million per occurrence, $2 million aggregate for non-sudden accidental releases; $3 million per occurrence for sudden accidental); financial assurance instruments must be available to EPA or the state to fund cleanup if the owner defaults
  • Subpart I — Use and Management of Containers (10s): containers must be in good condition; compatible with waste; kept closed except when adding or removing waste; inspected weekly; containers with incompatible wastes separated; stacking height limits; secondary containment for ignitable or reactive wastes
  • Subpart J — Tank Systems (11s): new tanks must have secondary containment (outer shell, vault, or double-walled construction) or be assessed by a PE; integrity assessment every year; leak detection systems; overfill and spill controls; response procedures for leaks (immediate notification, containment, root cause analysis); anchoring requirements for tanks susceptible to buoyancy
  • Subpart K — Surface Impoundments (11s): liner systems (double liner with leachate collection for new impoundments); liquid level management; inspection for subsidence, erosion, overtopping; closure by removing liquids and wastes; when "clean closure" isn't achievable, cap in place with post-closure care
  • Subpart N — Landfills (13s): liner design (double liner with leachate collection and detection layer between liners for new landfills); run-on/runoff controls; wind dispersal controls for fine-particle wastes; survey benchmarks; allowable daily cover; specific standards for liquids in landfills (generally prohibited); inspection for settlement, subsidence, erosion; post-closure 30-year groundwater monitoring and cap maintenance
  • Subpart O — Incinerators (8s): performance standards (destruction and removal efficiency — 99.99% for principal organic hazardous constituents; 99.9999% for certain dioxin-containing wastes); trial burns before operating; particulate matter, HCl, carbon monoxide emission limits; continuous monitoring; automatic waste feed cutoffs on exceedances
  • Subparts AA, BB, CC — Air Emission Standards (34s combined): organic vapor controls for process vents (Subpart AA), equipment leaks (valves, pumps, connectors — Subpart BB), and tanks, surface impoundments, and containers (Subpart CC); these standards apply to TSDFs managing hazardous wastes with ≥10 parts per million by weight organics; monitoring, inspection, and leak repair timelines specified

• 40 CFR Part 265 — Interim Status Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities (198 sections — the operating standards for TSDFs that were in existence before the RCRA permitting requirements kicked in, or that received hazardous waste for the first time and have notified EPA; these facilities operate under interim status pending issuance of a final RCRA permit; structure largely parallels Part 264 but with key differences):

  • Key distinction from Part 264: interim status facilities are not subject to the corrective action provisions of Part 264 Subpart F (SWMU releases) — instead, they must meet groundwater monitoring requirements under Subpart F of Part 265, which requires indicator parameter monitoring (pH, specific conductance, TOC, TOX) at a compliant well network to detect releases; if contamination is detected, the facility must characterize the release and notify EPA, but may then seek a variance or proceed to full Part 264 corrective action through the permitting process
  • Financial requirements (Subpart H, 11s): same general structure as Part 264 — closure cost estimate, post-closure estimate, financial assurance mechanism required; however, closure cost estimates for interim status facilities may be less detailed than Part 264 permits (no approved closure plan yet); EPA may require bond or trust fund for facilities with uncertain financial standing
  • Air emission standards (Subparts AA, BB, CC — 32s combined): identical substantive requirements to Part 264 air emission standards — organic vapor controls for process vents, equipment leak monitoring and repair, and controls for tanks/surface impoundments/containers handling waste with ≥10 ppm organics; the same standards apply regardless of permitted vs. interim status
  • Thermal treatment and chemical/physical/biological treatment (Subparts P, Q — 14s combined): Part 265 has unique subparts for thermal treatment (open burning, open detonation — prohibited except under special circumstances) and chemical/physical/biological treatment units that have no exact analogue in Part 264; these subparts reflect the historical variety of treatment methods at older RCRA facilities
  • Transition to Part 264: facilities in interim status must eventually obtain a RCRA permit under Part 270 or close; EPA has authority to terminate interim status if a facility does not apply for a permit on schedule; the permit process converts interim status operating conditions into enforceable permit conditions under Part 264; some facilities have remained in interim status for decades due to the complexity of the permit process at contaminated sites

• 40 CFR Part 270 — EPA Administered Permit Programs: The Hazardous Waste Permit Program (94 sections — the procedural rulebook for obtaining, modifying, and renewing RCRA Subtitle C permits; Part 270 is the process counterpart to Parts 264/265, which specify what standards permitted and interim-status TSDFs must meet; the permit program is the mechanism through which the abstract technical standards of Part 264 become enforceable permit conditions specific to each facility):

  • Subpart A — General Information (§§ 270.1–270.12): § 270.1 — the permit program covers all TSDFs treating, storing, or disposing of hazardous waste under RCRA Subtitle C; any TSDF that was in existence when the RCRA regulations became effective could operate under "interim status" without a full permit, but must eventually apply for a formal permit or close; § 270.2 — "RCRA permit" means a written authorization issued pursuant to the permit program; owning or operating a TSDF without a valid permit (or interim status authorization) is itself a RCRA violation subject to civil penalties up to $70,117/day; § 270.10 — the permit application process begins with the Part A form (basic facility and ownership information) and is completed with the Part B form (detailed technical information required by Part 264); many facilities have submitted Part A applications but their Part B applications remain under active review — these facilities have operated under interim status for decades
  • Subpart B — Permit Application (§§ 270.13–270.29): § 270.14 — Part B permit application content: applicants must provide detailed information covering every regulated unit — waste analysis plans (characterizing each waste stream accepted), inspection schedules, personnel training program descriptions, closure and post-closure plans, groundwater monitoring plans (including monitoring well placement and trigger levels), financial assurance documentation (cost estimates for closure, post-closure, and third-party liability), emergency response plans, and facility maps; the Part B is a comprehensive engineering and environmental document that typically runs hundreds of pages for complex TSDFs (landfills, incinerators, surface impoundments); § 270.17 — specific requirements for incinerators, including trial burn plans demonstrating DRE compliance
  • Subpart C — Permit Conditions (§§ 270.30–270.33): § 270.30 — every RCRA permit must contain the 21 standard conditions: duty to comply with all permit conditions, need to halt operations to maintain compliance, duty to mitigate, inspection rights for regulators, monitoring and reporting requirements, and prohibition on bypasses and upsets; § 270.32 — the permit writer incorporates the Part 264 standards as specific enforceable conditions tailored to the facility's actual waste types, processes, and geography — the generic Part 264 standards become a permit-specific obligation with numeric limits (e.g., specific groundwater monitoring constituent concentrations that trigger the response action program for that facility's hydrogeology)
  • Subpart D — Changes to Permit (§§ 270.40–270.42): § 270.41 — permit modifications fall into three classes by significance: Class 1 modifications (minor, administrative, or pre-approved changes — adding/deleting units at a facility) require only notification; Class 2 modifications (moderate changes to facility operations, new waste streams, or minor unit design changes) require public notice and a 60-day public comment period; Class 3 modifications (major expansions, new units, alternative design standards) require full public participation analogous to a new permit application; the three-class system balances the need for permit flexibility (Class 1/2) against public participation rights (Class 3)
  • Subpart H — Remedial Action Plans (§§ 270.100–270.155): EPA's Remedial Action Plan (RAP) program — a streamlined RCRA permit vehicle for TSDFs at cleanup sites where the primary goal is remedial action rather than ongoing commercial TSDF operations; RAPs are used where a facility is being cleaned up under a CERCLA consent decree or RCRA corrective action order — the remedial facility needs RCRA authority to treat or store hazardous waste generated during cleanup without triggering full TSDF permit requirements; § 270.100 — RAPs are issued when the owner and operator are different entities (e.g., a cleanup contractor treating contaminated soil at a third party's cleanup site)
  • Subpart J — RCRA Standardized Permits: a streamlined permit type introduced in 2005 for storage-only facilities and elementary neutralization units — TSDFs that perform only limited storage or minor chemical neutralization and don't pose the same risk as incinerators, landfills, or surface impoundments; standardized permits require only a facility information notice and compliance with a core set of performance standards rather than a full Part B application, significantly reducing the permit burden for simple operations

  RCRA permits are among the most legally significant and technically complex environmental permits in the U.S. regulatory system. A TSDF permit is the centerpiece document governing a facility's hazardous waste operations — it specifies which wastes may be accepted, at what rates, in what units, with what monitoring, and under what financial assurance. Permit issuance, modification, and renewal decisions are subject to public notice, public comment, and evidentiary public hearings; contested permit decisions can be appealed to the EPA Environmental Appeals Board. Permit duration: RCRA permits are valid for 10 years; renewal applications must be filed at least 180 days before expiration; a timely-filed renewal holds the permit in effect pending the renewal decision. State programs: authorized states issue RCRA permits under state law that must be at least as stringent as Part 270; in authorized states, the state issues and enforces the permit, not EPA, though EPA retains the right to initiate enforcement for violations. The backlog of unissued Part B permits is a longstanding RCRA program issue — some facilities have operated under interim status for 20–30 years without a final permit, primarily because the Part B application and permit issuance process is resource-intensive for both the applicant and the permitting authority.

• 40 CFR Part 266 — Standards for the Management of Specific Hazardous Wastes and Specific Types of Hazardous Waste Management Facilities (62 sections — special-case rules for categories of hazardous waste or management that don't fit cleanly into the generator/transporter/TSDF framework of Parts 262–265; the most significant subpart covers boilers and industrial furnaces (BIFs) that burn hazardous waste as fuel):

  Subpart H — Boilers and Industrial Furnaces (§§ 266.100–266.111): industrial boilers and furnaces that burn hazardous waste as fuel or for materials recovery are regulated as hazardous waste combustion units — distinct from commercial incinerators (which must meet Part 264 Subpart O standards) but subject to comparable emission controls:

  • § 266.100 — Applicability: covers owners and operators of boilers (combustion units using hot gas, steam, or electricity for process heating) and industrial furnaces (cement kilns, lime kilns, aggregate kilns, phosphate kilns, coke ovens, blast furnaces, smelting furnaces, and similar high-temperature industrial processes) that burn or process hazardous waste for energy or materials recovery
  • § 266.102 — Permit standards for burners: BIFs operating under a RCRA permit must meet standards controlling organic emissions, particulate matter, metals, and hydrogen chloride; the permit must specify operating parameters (combustion gas temperatures, waste feed rates, pollution control device conditions) that the facility must maintain
  • § 266.103 — Interim status standards: BIFs with interim status (operating while their permit application is pending) must meet substantive interim standards; interim status requires notification to EPA, hazardous waste analysis, and compliance with the emission standards below before accepting hazardous waste feeds
  • § 266.104 — Organic emission standards: the Destruction and Removal Efficiency (DRE) standard requires 99.99% destruction of principal organic hazardous constituents (POHCs) — the same standard as permitted incinerators; certain dioxin-containing wastes require 99.9999% DRE; trial burns must demonstrate DRE before a facility may operate under the standard
  • § 266.105 — Particulate matter standard: BIFs may not emit PM in excess of 180 milligrams per dry standard cubic meter (corrected for moisture and oxygen); BIFs burning hazardous waste exceeding this PM standard must install and operate baghouses, electrostatic precipitators, or wet scrubbers
  • § 266.106 — Metals emission standards: limits on antimony, arsenic, barium, beryllium, cadmium, chromium, lead, mercury, silver, and thallium (the "Subpart H metals"); metals limits are expressed as total annual feed rates (tons per year) or as emission concentrations; lead and cadmium from hazardous waste combustion are the metals of greatest regulatory concern in BIF operations
  • § 266.107 — Hydrogen chloride (HCl) and chlorine gas (Cl₂) standards: HCl emissions must not exceed 4 pounds/hour or must be reduced by 99%; Cl₂ emissions must not exceed 4 pounds/hour (the more limiting of the two); chlorinated solvents (trichloroethylene, methylene chloride, perchloroethylene) are common hazardous wastes burned in BIFs, making the HCl/Cl₂ standard operationally significant
  • § 266.108 — Small quantity on-site burner exemption: facilities burning de minimis quantities of hazardous waste they generate on-site (below specified thresholds) are exempt from the BIF permit and emission standards if the waste meets certain low-hazard criteria; this exemption covers small industrial boilers burning small volumes of on-site waste rather than commercial waste-to-energy operations
  • § 266.109 — Low risk waste exemption: waives the DRE trial burn requirement when the combustion gas stream contains very low concentrations of hazardous organics — based on an acceptable risk demonstration rather than a measured DRE

  The BIF regulations in Subpart H reflect a regulatory compromise: cement kilns, aggregate kilns, and industrial boilers that burn hazardous waste as fuel are performing a useful function (energy recovery reduces virgin fuel consumption), but they must still meet emission standards that protect surrounding communities. EPA's original rationale was that BIFs burning hazardous waste should face comparable emission limits as commercial incinerators dedicated to hazardous waste destruction — the "comparable to incinerators" standard is the organizing principle of Subpart H.

• 40 CFR Part 268 — Land Disposal Restrictions (LDR) (31 sections — RCRA's prohibition on land disposal of untreated hazardous waste; enacted by Congress in HSWA 1984 based on the finding that "land is not a permanent repository for hazardous waste"):

  • § 268.1 — Scope: any listed or characteristic hazardous waste is prohibited from land disposal unless it has been treated to meet the applicable treatment standard; "land disposal" means placement in a land-based unit — landfill, surface impoundment, waste pile, land treatment unit, injection well, salt dome, mine, or cave; the prohibition is triggered when the waste is generated (or hazardous waste is first identified), not when it reaches the disposal unit
  • § 268.3 — Dilution prohibited: generators cannot dilute hazardous waste with non-hazardous materials to achieve LDR compliance; the concentration must be reduced through actual treatment (destruction of hazardous constituents, detoxification, or immobilization), not mixing with clean material; this anti-dilution rule is among RCRA's most stringently enforced provisions
  • §§ 268.20–268.35 — Waste-specific prohibitions: each hazardous waste (listed F, K, P, U wastes and characteristic D wastes) has treatment standards — either concentration-based (mg/L or mg/kg thresholds for each regulated constituent in the Universal Treatment Standards table) or technology-based (must use incineration, stabilization, or specified treatment technology); wastes that cannot meet concentration standards without an available treatment technology may qualify for a case-by-case variance
  • § 268.40 — Treatment standards (the operational core): before a waste is land disposed, the generator or treatment facility must demonstrate — through representative sampling and analysis — that each regulated constituent meets the applicable standard; treatment must occur at a RCRA-permitted facility; documentation must be maintained for 3 years and accompany the waste to the disposal facility

  LDR transformed U.S. hazardous waste management: by 1990, over 95% of regulated hazardous waste was being treated before land disposal (vs. below 50% before LDR). The program continues to expand as EPA lists new wastes and revises treatment standards based on improved technologies. Recent rulemakings: 59 FR 48103 (September 1994) — universal treatment standards table; no major amendments since mid-1990s for the core framework.

• 40 CFR Part 273 — Standards for Universal Waste Management (43 sections — the RCRA streamlined management program for five categories of commonly generated hazardous waste that are better managed through collection and recycling than through the full Subtitle C cradle-to-grave regulatory framework; universal waste was designed to solve a real problem: strict RCRA Subtitle C requirements for batteries, mercury-containing lamps, and pesticides were causing businesses to illegally discard them as regular trash rather than deal with complex hazardous waste paperwork, resulting in more environmental harm than the regulations prevented):

  The five universal waste categories (§ 273.1):

  • Batteries (§ 273.2): primarily nickel-cadmium (NiCd), lead-acid, nickel-metal hydride, and lithium batteries from consumer electronics, power tools, UPS systems, and vehicles; excludes lead-acid batteries from vehicles (which have their own recycling infrastructure under state law); household alkaline batteries are generally not regulated as hazardous waste at all
  • Pesticides (§ 273.3): recalled and suspended pesticide products — products that have been recalled by the manufacturer or for which the EPA has suspended or cancelled registration; does not cover routine disposal of obsolete or unwanted pesticides by end users
  • Mercury-containing equipment (§ 273.4): thermostats, pressure/flow switches, flame sensors, electric switches, and other devices containing mercury; the most regulated category for building owners and facility managers (mercury-containing thermostats were ubiquitous in pre-1990s HVAC systems)
  • Lamps (§ 273.5): fluorescent lamps (linear, compact, UV), high-intensity discharge (HID) lamps (metal halide, high-pressure sodium, mercury vapor), and neon signs; the mercury content of a single fluorescent tube (average 4 mg for newer lamps) classifies it as a hazardous waste under RCRA if tested; the universal waste rule channels hundreds of millions of lamps per year toward recycling rather than landfill
  • Aerosol cans (§ 273.1): added by EPA in 2019 (84 FR 67202); aerosol cans that are hazardous because of their flammable contents or compressed gas; the 2019 rule brought aerosol can management under the universal waste framework to reduce illegal disposal and simplify compliance for retailers and distributors

  Regulatory structure — handler tiers (§§ 273.10–273.70):

  • Small quantity handlers (SQHs) — accumulate less than 5,000 kg total universal waste at any time: no EPA ID number required (§ 273.12); no manifest required; no time limit for accumulation (§ 273.15 — up to 1 year); must label containers with "Universal Waste — [Batteries/Lamps/Mercury/Pesticides/Aerosol Cans]"; must train employees on waste handling (§ 273.16); must contain releases immediately (§ 273.17); must ship only to other universal waste handlers or to permitted RCRA TSDFs
  • Large quantity handlers (LQHs) — accumulate 5,000 kg or more: must obtain an EPA ID number; slightly stricter recordkeeping; still no manifest; 1-year accumulation limit applies; must submit an annual report
  • Universal waste transporters — more permissive than hazardous waste transporter rules; no manifest required; must respond to releases
  • Destination facilities — the recyclers and TSDFs that receive universal waste; must be permitted under RCRA or meet state equivalent standards for recycling

  Part 273's practical impact is measured in collection infrastructure: the universal waste framework is why you can drop off dead fluorescent tubes at Home Depot, return old batteries to Best Buy, and recycle mercury thermostats through building supply distributors — the retail collection box programs these companies operate would not exist under full Subtitle C regulation. 84 FR 67202 (December 2019) added aerosol cans as the fifth universal waste category, benefiting retailers with large reverse logistics flows of unsold or returned aerosol products.

• 40 CFR Part 279 — Standards for the Management of Used Oil (47 sections — EPA's standalone regulatory program for used oil, the lubricating oil drained from engines, transmissions, hydraulic systems, and industrial machinery after use; used oil occupies an unusual legal position under RCRA: it is a solid waste but is not classified as hazardous waste unless it fails a specification standard or is shown to have been mixed with hazardous waste; Congress made this policy choice to encourage recycling and re-refining rather than disposal, while still requiring environmentally protective management):

  Core framework and specifications:

  • § 279.10 — Applicability and rebuttable presumption: used oil is presumed to have been mixed with halogenated hazardous waste (and thus regulated as hazardous waste) if its total halogen content exceeds 1,000 ppm — because chlorinated solvents and other halogenated compounds are the most common industrial contaminants that end up illegally mixed into used oil; the presumption can be rebutted if the generator can demonstrate the halogens come from non-hazardous additives or inherent contamination; this "rebuttable presumption" is the mechanism that prevents used oil from becoming a loophole for disposing of halogenated hazardous solvents
  • § 279.11 — Specification used oil: used oil that meets all three specifications — arsenic ≤5 ppm, cadmium ≤2 ppm, chromium ≤10 ppm, lead ≤100 ppm; flash point ≥100°F; total halogens ≤4,000 ppm (or rebutted) — is "specification used oil" and may be burned for energy recovery without being regulated as an off-specification fuel; specification used oil is largely exempt from fuel-burning controls under Part 279
  • § 279.12 — Prohibitions: used oil may not be managed in surface impoundments or waste piles (unless permitted under Part 264/265); may not be used as a dust suppressant on roads or other surfaces — one of the most environmentally harmful historic disposal practices (used oil applied to unpaved roads contains heavy metals and carcinogens that leach into soil and groundwater); may not be mixed with hazardous waste (other than through incidental processing)

  Generator standards (Subpart C — §§ 279.20–279.24): any person who generates used oil in the course of business is a used oil generator; household do-it-yourself (DIY) oil changers are expressly excluded (their used oil is household waste). Generator requirements are deliberately light:

  • § 279.21 — A generator who mixes hazardous waste with used oil must manage the entire mixture as hazardous waste under Subtitle C (the "mixing rule" for used oil)
  • § 279.22 — Storage requirements: used oil must be stored in tanks or containers in good condition; no visible leaks; containers/tanks marked "Used Oil"; subject to Spill Prevention, Control, and Countermeasures requirements (40 CFR Part 112) for quantities above SPCC thresholds
  • § 279.23 — Generators may burn small quantities of their own used oil on-site in space heaters with a capacity of ≤500,000 BTU/hour — allowing auto repair shops and industrial facilities to heat their own facilities with oil they generate without triggering the full burner standards
  • § 279.24 — Off-site shipments must go to a transporter or processor/re-refiner with an EPA identification number; generators may not ship to unlicensed handlers

  Collection centers (Subpart D — §§ 279.30–279.32): do-it-yourselfer (DIY) used oil collection centers — typically auto parts stores (AutoZone, O'Reilly, NAPA) and service stations — may accept used oil from household vehicle owners with minimal regulatory burden; they must store used oil properly and arrange for pickup by licensed transporters but are exempt from most generator and transporter requirements that would otherwise apply

  Transporter standards (Subpart E — §§ 279.40–279.47):

  • § 279.42 — Transporters must notify EPA and obtain an EPA identification number before transporting used oil
  • § 279.44 — Rebuttable presumption testing duty: transporters must test or otherwise determine whether the total halogen content of accepted used oil exceeds 1,000 ppm; a transporter who accepts oil exceeding this threshold without rebuttal is handling hazardous waste, not used oil
  • § 279.46 — Tracking requirements: transporters must maintain records for each shipment (generator name/address, quantity, delivery destination) for 3 years; this creates a paper chain from generation through disposal analogous to the hazardous waste manifest, but without the formal multi-copy manifest format

  Processor/re-refiner and burner standards (Subparts F–G — §§ 279.50–279.67): facilities that process used oil (blend, filter, remove water) or burn it for energy recovery (industrial boilers, space heaters, industrial furnaces, utility boilers) must obtain EPA ID numbers, meet storage and recordkeeping requirements, and — for burners of off-specification used oil — comply with additional permit and emission controls; re-refiners that reclaim used oil back into base lubricating oil are the most environmentally beneficial destination and receive the most favorable regulatory treatment

  Part 279's regulatory design reflects a deliberate choice to treat used oil differently from other hazardous wastes: by keeping the base regulatory burden light while sharply penalizing hazardous-waste mixing and road application, EPA channeled approximately 2.4 billion liters of used oil per year (U.S. generation estimate) toward recycling and re-refining rather than landfill disposal. The re-refining of used oil into base lubricant is particularly resource-efficient — re-refined used oil meets the same API performance specifications as virgin lubricant, and the process consumes approximately 65% less energy than refining crude oil into base lube.

• 40 CFR Part 271 — Requirements for Authorization of State Hazardous Waste Programs: the criteria a state must meet to receive EPA authorization to administer the hazardous waste management program under RCRA Subtitle C in lieu of the federal program; to receive authorization, a state must demonstrate that its hazardous waste program is "equivalent to" and "consistent with" the federal program and provides adequate enforcement; key criteria include: state laws must have requirements at least as stringent as RCRA and its implementing regulations; the state must have legal authority to issue permits, inspect facilities, take enforcement actions (including penalty authority), and maintain a public record; the state must demonstrate authority to address interstate waste movements; once authorized, the state becomes the primary permitting and enforcement authority (not EPA) for all RCRA Subtitle C activities within its jurisdiction, though EPA retains oversight authority and enforcement discretion; tribal lands are excluded from state program authority and remain under direct EPA oversight regardless of state authorization status

• 40 CFR Part 272 — Approved State Hazardous Waste Management Programs: the state-by-state registry of EPA's approval decisions under Part 271; for each of the ~48 authorized states, Part 272 records the date of authorization, the specific state statutes and regulations that received authorization, any conditions attached to the authorization, and whether authorization is "base program" authorization (covering the original RCRA requirements) or includes "HSWA" authorization (covering the 1984 Hazardous and Solid Waste Amendments, which added land disposal restrictions, minimum technology requirements, and other new federal mandates); states must apply separately for HSWA authorization because EPA initially retained authority for HSWA requirements even in states with base authorization; in practice, states with partial HSWA authorization have a split jurisdiction — they administer the pre-HSWA program while EPA administers HSWA-added requirements; Part 272 is the reference document that determines which law applies at any specific RCRA facility in an authorized state

Subtitle D — Solid Waste:

• 40 CFR Part 257 — Criteria for Classification of Solid Waste Disposal Facilities and Practices (60 sections — the RCRA Subtitle D companion rule to Part 258; establishes minimum federal criteria for solid waste disposal that is NOT municipal solid waste (governed by Part 258) and hosts the landmark Coal Combustion Residuals (CCR) rule covering fly ash, bottom ash, and boiler slag from coal-fired power plants):

  Subpart A — General criteria (§§ 257.1–257.4): baseline location and design standards for non-municipal solid waste disposal facilities — floodplain restrictions (disposal in 100-year floodplains prohibited unless demonstrated to have no adverse effect on water quality), endangered species protections, surface water discharge prohibition, and airport siting restrictions (no facility within 10,000 feet of an airport runway that would attract birds hazardous to aircraft)

  Subpart B — Coal Combustion Residuals (CCR) (§§ 257.50–257.107) — the major rulemaking finalized April 17, 2015 (80 FR 21302) covering approximately 735 active CCR landfills and surface impoundments at U.S. coal power plants; coal combustion generates roughly 100 million tons per year of CCR (fly ash, bottom ash, boiler slag, and flue gas desulfurization material — "gypsum"); EPA regulated CCR under Subtitle D (non-hazardous solid waste) rather than Subtitle C, meaning the program is self-implementing (no permits required) but requires public transparency through mandatory internet posting:

  • § 257.70–257.74 — Location restrictions: new CCR units prohibited in wetlands, unstable areas, earthquake-hazard zones, floodplains, and seismic impact zones; existing units in restricted locations must demonstrate structural integrity or close
  • § 257.71 — Liner design criteria: existing CCR surface impoundments with unlined or deficient liners must close or retrofit to a composite liner (geomembrane over compacted soil or GCL); new units must have composite liners meeting specific permeability criteria (leachate collection systems required for landfills)
  • §§ 257.90–257.98 — Groundwater monitoring and corrective action: owners must establish a groundwater monitoring network; detection monitoring (Appendix III constituents — arsenic, barium, boron, cadmium, chromium, cobalt, fluoride, lead, lithium, molybdenum, radium, selenium, thallium); upon detection, advance to assessment monitoring (Appendix IV hazardous constituents); upon exceedance, conduct corrective action to return groundwater to background levels; monitoring results must be posted on the facility's public website
  • § 257.101 — Closure and retrofit triggers: existing unlined CCR surface impoundments that cannot demonstrate the liner is equivalent to a composite liner must close; the owner must choose between cap-in-place (leaving CCR in the ground under an engineered cap) or excavation and relocation; the closure deadline triggered extended litigation and EPA extensions — the Biden-era 2024 amendments accelerated closure timelines; impoundments that failed safety assessments must close regardless of timeline
  • § 257.102 — Closure performance standard: cap-in-place closure requires a multi-layer cap system that controls infiltration, erosion, and subsidence for 30 years of post-closure care; the cap must achieve an infiltration rate ≤ 1×10⁻⁵ cm/sec (equivalent to a compacted clay liner); structural integrity assessment required before closure begins
  • § 257.104 — Post-closure care: 30 years of post-closure groundwater monitoring, cap maintenance, and annual inspections after any cap-in-place closure; EPA may extend or shorten based on site-specific conditions
  • § 257.107 — Public internet site: every CCR unit subject to the rule must maintain a publicly accessible website posting all groundwater monitoring data, structural stability assessments, CCR unit design drawings, closure plans, and inspection reports; the website must be updated within 30 days of each monitoring event; this transparency requirement is the enforcement mechanism — without EPA permits, public access to data is the primary accountability tool; EPA's CCR website database links to all facility sites

  The CCR rule has been one of EPA's most litigated rulemakings. The 2015 rule was challenged by utilities (arguing requirements were too strict) and environmental groups (arguing EPA should have regulated CCR as hazardous waste). A 2018 D.C. Circuit decision (Utility Solid Waste Activities Group v. EPA) vacated portions of the rule and required EPA to strengthen closure requirements for unlined impoundments. Subsequent Biden and Trump EPA actions continued to modify the rule — the 2024 amendments (89 FR 38950) established a new Legacy CCR Surface Impoundment category for impoundments that stopped receiving CCR before the 2015 rule but are still filled with ash requiring management.

• 40 CFR Part 258 — Municipal solid waste landfill criteria: composite liner requirements, leachate collection, groundwater monitoring, methane control, closure/post-closure (30 years), financial assurance

Subtitle I — Underground Storage Tanks:

• 40 CFR Part 280 — Underground storage tank regulations: release detection, corrosion protection, spill/overfill prevention, financial responsibility ($1M per occurrence), corrective action for confirmed releases

• 40 CFR Part 281 — State UST program authorization: criteria for state program approval to operate in lieu of the federal program

• 40 CFR Part 282 — Approved Underground Storage Tank Programs (53 sections — the state-specific authorization register implementing RCRA § 9004, 42 U.S.C. § 6991c; states whose UST programs meet or exceed Part 280's minimum requirements may apply for EPA approval to administer UST regulation in lieu of the federal program; once approved, the state program substitutes for Part 280 enforcement within that state):

  • § 282.1 — Purpose and scope: establishes the approval framework for state UST programs under RCRA § 9004; a state "in lieu of" approval means the state — not EPA Region — is the primary enforcement authority for UST release detection, corrosion protection, spill/overfill prevention, and corrective action within that state's boundaries; tribal lands are generally excluded from state program jurisdiction and remain under direct EPA oversight
  • § 282.2 — Incorporation by reference: the state program approval regulations incorporate by reference the state regulatory materials submitted with each approval application — state statutes, regulations, and any conditions EPA attached to the approval; when a state amends its UST rules, it must notify EPA and, for significant changes, obtain revised approval to maintain "in lieu of" status
  • State-specific approval entries (§§ 282.50–282.102): Part 282 contains individual approval entries for each approved state and territory, identifying (1) the date of original approval, (2) the specific state regulations approved (by state code citation), (3) any conditions or limitations on the approval, and (4) whether the approval covers the full Part 280 program or only certain elements; as of 2026, approximately 39 states and territories have received Part 282 approval for some or all UST program elements; example entries include Alabama (§ 282.50), Arkansas (§ 282.51), Colorado (§ 282.52), Connecticut (§ 282.53), Delaware (§ 282.55), Puerto Rico (§ 282.82), and others
  • Approval standards: to obtain Part 282 approval, a state program must demonstrate it is "no less stringent" than Part 280 on release detection requirements, corrective action standards, financial responsibility requirements, and the technical standards for tank systems; "no less stringent" means the state rules must achieve at least the same level of protection — states may impose stricter requirements and still be approved; states with stricter requirements (e.g., California's more stringent secondary containment rules) apply their own standards, not Part 280 minimums, within their jurisdiction
  • Partial approvals: some states have approval for only certain elements of the UST program; EPA retains jurisdiction over unapproved elements; partial approvals are common where a state's financial responsibility rules or corrective action standards haven't yet been fully revised to match Part 280

  The Part 282 approval framework explains why UST compliance requirements vary significantly by state — a facility in an approved state must comply with that state's regulations and deal with the state agency, while a facility in a non-approved state must comply with federal Part 280 and deal with the EPA Region. For most petroleum UST operators (gas stations, fleet fueling facilities, heating oil tanks), the relevant compliance requirements in any given state are found in the state's own UST code, not directly in 40 CFR Part 280, even though Part 280 sets the floor those state rules must meet.

How It Works

RCRA is the federal framework for managing waste from generation to disposal — often called "cradle-to-grave" regulation. Unlike Superfund (CERCLA), which addresses contamination from past waste disposal, RCRA regulates the ongoing management of solid and hazardous waste to prevent future contamination. RCRA is one of several major statutes administered by the EPA, alongside the Clean Water Act, TSCA, and EPCRA. Subtitle C imposes the most stringent requirements on hazardous waste — waste that is either "listed" by EPA (specific industrial wastes and chemical products on the F, K, P, and U lists) or exhibits a hazardous "characteristic" (ignitability, corrosivity, reactivity, or toxicity). Generators must identify, characterize, label, and manifest their hazardous waste; transporters must carry manifests and comply with DOT hazmat regulations; and Treatment, Storage, and Disposal Facilities (TSDFs) must obtain RCRA permits, meet technology standards (liners, leachate collection, groundwater monitoring, combustion standards for incinerators), and maintain financial assurance for closure. The land disposal restrictions (LDR) program — added by the 1984 amendments — generally prohibits land disposal of hazardous waste unless it first meets specific treatment standards.

Subtitle D governs ordinary garbage — household, commercial, and non-hazardous industrial waste — setting minimum federal criteria for municipal solid waste landfills (liners, leachate collection, methane control, 30-year post-closure care) while leaving implementation to state and local governments; open dumping is prohibited. The U.S. generates approximately 290 million tons of municipal solid waste per year. Subtitle I regulates approximately 540,000 active underground storage tanks (mostly at gas stations), requiring leak detection equipment, spill and overflow prevention, corrosion protection, and financial responsibility for cleanup; the Leaking Underground Storage Tank (LUST) Trust Fund (funded by a federal gas tax) covers cleanup when the responsible owner cannot be found or cannot pay. Coal mining waste is separately regulated under the Surface Mining Control and Reclamation Act. RCRA is primarily implemented by state agencies — approximately 48 states operate their own authorized RCRA programs that meet or exceed federal requirements, with EPA retaining enforcement authority for the remaining states and for federal facilities.
