Generator Size Categories

  • 1. How is “generator” defined in the hazardous waste regulations?

    A generator is defined as any person, by site, whose act or process produces hazardous waste identified or listed in part 261 or whose act first causes a hazardous waste to become subject to regulation (40 CFR section 260.10). The generator of a waste may not necessarily be the person who actually produced the waste. For example, a contractor who removes hazardous residues from a product storage tank is the first person to cause the waste to become subject to regulation, rather than the owner of the tank. Although the person removing the waste from the unit is not the owner or operator of the unit, he or she may be considered a generator. The owner or operator of the unit may also be considered a generator since the act of operating the unit led to the generation of the hazardous waste. In other words, both the person that removed the waste and the owner or operator of the tank are considered to be co-generators. In cases where one or more persons meet the definition of generator, all persons are jointly and severally liable for compliance with the generator regulations (45 FR 72024, 72026; October 30, 1980).

  • 2. Which wastes are counted towards a monthly generator category determination?

    Any waste that meets the definition of hazardous waste in 40 CFR part 261 and is not exempt from regulation must be counted toward your generator category. Please review the regulations at 40 CFR section 262.11 for how to make a hazardous waste determination. Be sure to include in your count wastes that are accumulated on site for any time before disposal or recycling, placed directly into an on-site treatment or disposal unit, or generated as still bottoms or sludges and removed from storage tanks. Section 262.13(c) identifies the wastes that are not included in the monthly determinations.

    Additional guidance on counting wastes towards a monthly generator status determination is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Memo, Cotsworth to Peters, March 22, 1999 (RCRA Online #14333).

    • Monthly Call Center Report Question, November 1983 (RCRA Online #12151).
  • 3. What is the maximum amount of hazardous waste that can be generated by a large quantity generator (LQG)?

    There is no maximum amount of waste that can be generated by a large quantity generator, the largest classification of generator. All the hazardous waste must be managed according to 40 CFR section 262.17. Among other standards, there are limits on the amount of time the waste may be accumulated and the type of containers used to accumulate it.

    The two smaller classifications, very small quantity generator (VSQG) and small quantity generator (SQG) both have maximum amounts. VSQGs have upper limits of 100 kg of non-acute hazardous waste per month and 1 kg of acute hazardous waste per calendar month and SQGs have limits of 1,000 kg of non-acute hazardous waste and 1 kg of acute hazardous waste (see 40 CFR section 262.13 Table 1).

Generator Treatment and Management of Hazardous Waste

  • 1. How long can a generator accumulate hazardous waste on site without a permit or interim status?

    The length of time a generator is allowed to accumulate hazardous waste on site will vary depending on how much hazardous waste it generates in a calendar month. A large quantity generator (LQG) can accumulate hazardous waste on site for up to 90 days in specified units without obtaining a storage permit or interim status, provided the facility complies with Part 262 management standards for specific units (section 262.17). A small quantity generator (SQG) can accumulate up to 6,000 kg of hazardous waste for 180 days or less in tanks or containers if the facility complies with the modified standards in section 262.16. An SQG can accumulate hazardous waste for up to 270 days if the treatment, storage, or disposal facility is 200 miles or more away (sections 262.16(d)). Generators can receive a 30-day extension for accumulation of hazardous waste if uncontrollable and unforeseen circumstances cause them to accumulate waste on site for longer than the allowed time period. Such an extension may be granted by a Regional Administrator or authorized state on a case-by-case basis (sections 262.16(d) and 262.17(b)).

    Additional guidance on generator accumulation times is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Monthly Call Center Report Question, November 1986 (RCRA Online #12775).
    • Memo, Straus to Katona, March 12, 1985 (RCRA Online #11062).
  • 3. What are the requirements for inspecting containers of hazardous waste in central accumulation areas?

    Large quantity generators (LQG) and small quantity generators (SQG) are required to perform weekly inspections in areas where containers are stored (section 262.16(b)(2)(iv) and section 262.17(a)(1)(v)). Specifically, generators should check for leaks and deterioration caused by corrosion or other factors. There is no federal requirement for VSQGs to perform inspections on hazardous waste containers. States, however, can be more stringent than the Federal regulations and may require inspections of containers from all generators.

    See section 262.16(b)(3) for inspection requirements for SQGs accumulating hazardous waste in tanks and section 265.195 for LQGs accumulating hazardous waste in tanks.

  • 4. Can generators treat hazardous waste without obtaining a permit?

    Large quantity generators (LQGs) and small quantity generators (SQGs) can treat hazardous waste in tanks, containers, or containment buildings without obtaining a permit or interim status provided they comply with the requirements in section 262.15–17, which include references to unit-specific requirements in Part 265 (51 FR 10146, 10168; March 24, 1986). For example, in order to treat hazardous waste on site for less than 90 days in accordance with section 262.16 and section 262.17, a small quantity generator must place the waste in containers in compliance with section 262.16(b)(2), tanks in compliance with section 262.16(b)(3), or containment buildings in compliance with section 262.16(b)(5). A large quantity generator must comply with section 262.17(a)((1) for containers, section 262.17(a)(2) for tanks, or section 262.17(a)(4) for containment buildings. LQGs are also subject to any applicable air emissions requirements at 40 CFR part 265 subparts AA, BB, and CC.

    Under this provision, generators can treat only the hazardous waste generated on site. A permit would be required to treat hazardous waste consolidated from off-site locations (Memo, Cotsworth to Regions, August 16, 2002 (RCRA Online #14618 (4 pp, 18.2 K, About PDF))). Furthermore, generators cannot treat hazardous waste by thermal treatment or incineration without obtaining a permit (see 51 FR 10146, 10168; March 24, 1986 and the Call Center Monthly Report Question dated January 2003 (RCRA Online #14662 (2 pp, 12 K, About PDF))). In addition, generators who treat hazardous waste to meet the land disposal restriction treatment standards must comply with the notification requirements in section 268.7(a)(5) and have a waste analysis plan on site (Call Center Monthly Report Question dated August 1992 (RCRA Online #13553 (2 pp, 31.8 K, About PDF))).

    Generators should check with their implementing agencies before treating waste in accordance with section 262.16 and section 262.17. Some authorized states are more stringent than the federal program and may require a permit for generator treatment activities. Generators should contact their state solid/hazardous waste program officers to determine if they need a permit to treat hazardous waste on site.

    Additional guidance regarding generator treatment is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Memo, Cotsworth to Steward, October 23, 1998 (RCRA Online #14466).
    • Memo, Shapiro to Directors, October 17, 1994 (RCRA Online #11881).
    • Memo, Lowrance to McCarley, September 20, 1991 (RCRA Online #11641).
    • Call Center Monthly Report Question, January 1988 (RCRA Online #13117).
    • Memo, Williams to Lenher, July 25, 1986 (RCRA Online #12694).
  • 5. May a generator conduct thermal treatment without obtaining a permit?

    A generator may not conduct thermal treatment without a permit. Thermal treatment is regulated under part 265 subpart P; parts 264/265 subpart O; part 264 subpart X; or part 266 subpart H. The generator is, however, allowed to conduct non-thermal treatment in containers, tanks, containment buildings, and drip pads without obtaining a permit as long as they comply with the standards in section 262.16 and section 262.17, as appropriate.

  • 6. When must a waste be managed as hazardous waste if the generator is awaiting characterization test results?

    The point of generation for hazardous waste is when it is first produced or first becomes subject to hazardous waste regulations, not when a generator first receives waste analysis results. The hazardous waste generator regulations in 40 CFR part 262 apply as soon as waste is generated, and the accumulation period applies either as soon as the waste is generated or when waste is removed from the satellite accumulation area (Memo, Lowrance to Axtell; April 21, 1989 (RCRA Online #11424 (2 pp, 34 K, About PDF)). If a generator is unsure if the waste being tested is a hazardous waste, the generator must manage it as hazardous waste and label the containers with the potential hazard of the contents (e.g., ignitable, toxic, reactive, corrosive), the words “hazardous waste” (they could also use “hazardous waste pending analysis” to make it clear that testing is not yet complete), and the date upon which accumulation began. That way the generator will remain in compliance with the part 262 labeling requirements if the waste is determined to be hazardous. If the waste is determined to be non-hazardous, the generator can remove the hazardous waste labels at that point.

  • 8. A generator palletizes and shrink wraps expired consumer goods in their original packaging. The expired consumer goods are hazardous waste. Does the generator need to label every container “hazardous waste” or can it put a single label on each pallet?

    A shrink-wrapped pallet does not meet the definition of container in section 260.10, nor would it meet the container standards in part 262. Pursuant to the Resource Conservation and Recovery Act (RCRA) regulations, each container used for on-site hazardous waste accumulation must be labeled or marked clearly with the words “Hazardous Waste,” an indication of the hazards of the contents, and the date on which accumulation began (sections 262.16(b)(6) and 262.17(a)(5)). Therefore, the generator must label each individual container on the pallet. A generator may also label the pallet, if it so chooses, but the pallet label does not in and of itself satisfy the regulatory requirements of part 262.

    During transportation, the consumer goods are subject to Department of Transportation (DOT) requirements for the transportation of hazardous materials, of which manifested hazardous waste is a subset. For more information about the DOT regulations, contact the Hazardous Materials Information Center at 1-800-467-4922.

    Additional guidance regarding the labeling of hazardous waste containers in preparation for transport is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database

    • Memo, Williams to Smith, November 17, 1987 (RCRA Online #11303).
    • Memo, Weddle to Staab, January 10, 1984 (RCRA Online #11031).
  • 9. What is the definition of “closed” for the purposes of complying with 40 CFR sections 262.16(b)(2) and 262.17(a)(1)?

    While EPA has not provided a definition of "closed" for the purpose of compliance with the hazardous waste generator and treatment, storage and disposal facility (TSDF) regulations, the Agency has provided guidance on proper techniques for container closure. For instance, for typical containers, such as 55-gallon drums, EPA recommends the container cover be properly secured with snap rings tightly bolted; bungholes capped, and, where appropriate, pressure-vacuum relief valves to maintain the container’s internal pressure to avoid explosions. EPA generally considers a container accumulating free liquids or liquid hazardous wastes to be “closed” when all openings or lids are properly and securely affixed to the container, except when wastes are actually being added to or removed from the container. Liquid hazardous wastes also can be accumulated in open-head drums or open-top containers (e.g., where the entire lid is removable and typically secured with a ring and bolts or snap ring) and meet the definition of “closed” provided the rings are clamped or bolted to the container. The container could be considered closed if the lid covers the container top securely. For solid and semi-solid hazardous wastes, EPA considers the container "closed" as long as there is complete contact between the lid and the rim all around the top of the container.

    This guidance and further details are available in the following memoranda available in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Memo, Dellinger to Regions, December 3, 2009 (this memo is available as an attachment to RCRA Online #14826).
    • “Closed Container Guidance: Questions and Answers” Betsy Devlin, November 3, 2011 (RCRA Online #14826).
  • 12. May a very small quantity generator (VSQG) treat hazardous waste on site without a permit?

    Very small quantity generators (VSQGs) may treat hazardous waste on site without a permit provided they meet one of the conditions in 40 CFR section 262.14(a)(5)(iii–vii) or (xi). If a VSQG is not one of these types of facilities, it must have a permit under part 270, or operate under interim status under parts 270 and 265 before treating or disposing of waste on site. (See 61 FR 34252, July 1, 1996). However, federal regulations allow states to adopt more stringent regulations if they choose, and some states have chosen not to exempt VSQGs from many of the hazardous waste requirements. Therefore, VSQGs should contact their state solid/hazardous waste program officers to determine regulations for VSQGs. Additional guidance regarding VSQG requirements is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Monthly Call Center Report Question, January 2003 (RCRA Online #14662).
    • Memo, Shapiro to Kim, May 1, 1996 (RCRA Online #14030).
  • 13. May a small quantity generator (SQG) treat hazardous waste in containment buildings or on drip pads?

    An SQG can accumulate and treat hazardous waste on drip pads or in containment buildings if the SQG complies with the unit specific accumulation requirements in section 262.16(b)(4) for drip pads and section 262.16(b)(5) for containment buildings. These requirements include accumulation time limits, labeling, and recordkeeping and also refer directly to part 265 subpart W for drip pads and part 265 subpart DD for containment buildings for technical standards, operation requirements, and closure.

    The federal requirements regarding small quantity generator use of drip pads and containment buildings were revised as part of the November 28, 2016, Hazardous Waste Generator Improvements Rule. The Hazardous Waste Generator Improvements Final Rule is effective federally as of May 30, 2017; however, implementation in a particular state depends on whether the state has adopted the rule. A discussion of the effect that this final rule will have on state authorization is available on page 85801 of the rule. Information about how the rule will affect the requirements in this FAQ in a particular state is best obtained from the state hazardous waste program. A list of state hazardous waste programs is available here.

  • 15. Should a small quantity generator (SQG) performing on-site treatment of hazardous waste in a tank comply with the section 262.16(b)(3) standards or is the SQG subject to all of part 265 subpart J?

    An SQG performing on-site treatment in a tank would continue to follow the standards in section 262.16(b)(3). Since the section 262.16 tank standards are designed to ensure that the integrity of a tank or container is not breached, the same standards apply regardless of whether a unit is used for treatment or accumulation (56 FR 10146, 10168; March 24, 1986). When originally promulgated, the structure and content of the regulations now in section 262.16(b)(3) were intended to supplant subpart J requirements for SQGs rather than supplement them. Therefore, an SQG complies with section 265.16(b)(3) instead of all of the subpart J regulations when accumulating or treating hazardous waste in tanks. Generators should be aware that authorized states can be more stringent than EPA and should always confer with the implementing agency to determine applicable unit standards.

    Note: The location of the SQG-specific tank requirements moved from section 265.201 to section 262.16(b)(3) as part of the November 28, 2016, Generator Improvements Rule, which reorganized some of the generator regulations, but the contents of the requirements did not change and preamble language and other references in memos and guidance to section 265.201 still applies.

  • 16. Can a generator accept hazardous waste from one of the corporation's other facilities before shipping all of the waste to a permitted treatment, storage and disposal facility (TSDF)?

    Under most circumstances, a generator cannot accept a shipment of hazardous waste from another company location, unless the receiving generator is also a designated facility. A designated facility is defined as any hazardous waste TSDF which has received a permit or interim status, or a recycling facility that is regulated under Section 261.6(c)(2) or part 266 subpart F (Section 260.10). A generator that is subject to the requirements in part 262 must prepare a hazardous waste manifest for any off-site shipment of hazardous waste. On that manifest, the generator must designate a facility that is permitted to handle its hazardous waste (Section 262.20(b)). Thus, once a generator sends hazardous waste off site, it must be destined for a designated facility.

    Under the provisions of the 2016 Generator Improvements Rule, very small quantity generators (VSQGs) can ship their waste to a large quantity generator (LQG) under the control of the same company for consolidation before sending it on to a designated facility if the VSQG complies with the conditions at section 262.14(a)(5)(viii). The waste does not have to travel under a manifest when being sent from the VSQG to the LQG, but it does have to be managed as LQG waste by the LQG and can only be accumulated for 90 days once it reaches the LQG.

    The consolidation provision for VSQGs were added as part of the November 28, 2016, Hazardous Waste Generator Improvements Rule. The Hazardous Waste Generator Improvements Final Rule is effective federally as of May 30, 2017; however, implementation in a particular state depends on whether the state has adopted the rule. You should check to see if your state has adopted this consolidation provision before using it. Information about how the rule will affect the requirements in this FAQ in a particular state is best obtained from the state hazardous waste program. A list of state hazardous waste programs is available here.

Notification and Reporting: EPA Identification (ID) Number

  • 1. A generator has multiple structures within the same contiguous property. Is each structure required to have an individual EPA identification number?

    For the purposes of generator notification and obtaining EPA identification numbers, and assuming the structures are on-site as defined in section 260.10, one identification number is sufficient for all structures at the facility site (Memo, Shapiro to Wojdyla, May 1, 1996 (RCRA Online #14031)). EPA identification numbers are issued to facilities on a by-site basis (Memo, Barnes to Bider, August 15, 1989 (RCRA Online #11456)). There is no regulatory definition for the term “by-site”; however, it refers to where a hazardous waste is generated (Memo, Shapiro to Wojdyla, May 1, 1996 (RCRA Online #14031)). For example, if a single company operates three laboratories on a single piece of property, all three laboratories may share one EPA ID number and the waste from all three laboratories may be evaluated together. However, if the company operates three laboratories at three different locations that are not considered to be on contiguous property, each laboratory is viewed as a separate potential generator and is required to obtain an individual EPA ID number (Memo, Shapiro to Wojdyla, May 1, 1996 (RCRA Online #14031)). Furthermore, when the laboratories or structures are owned by different people, the generator must obtain one identification number for each laboratory or structure even if the regulated activity is taking place on a contiguous piece of property (Monthly Report Question; February 1988 (RCRA Online #13129)). The guidance memoranda referenced above are available in the Resource Conservation and Recovery Act (RCRA) Online database.

    A generator may obtain an EPA ID number by filling out Form 8700-12, Notification of Regulated Waste Activity, and submitting it to the appropriate EPA Regional or authorized state RCRA implementing agency. The notification forms are available from EPA Regional offices, state hazardous waste offices, or on the RCRAInfo Web website.

    Additional guidance on EPA identification numbers is available in the following memos in the RCRA Online database:

    • Memo, Petruska to Kuszaj, August 22, 1995 (RCRA Online #11916).
    • Memo, Daneker to Kawatachi, August 3, 1983 (RCRA Online #11028).

Notification and Reporting: Manifest

  • 4. How does a hazardous waste generator certify compliance with the waste minimization requirements in the Resource Conservation and Recovery Act (RCRA) section 1003(b)?

    Hazardous waste generators must certify compliance with waste minimization requirements in RCRA section 1003(b) when preparing a hazardous waste manifest. Large quantity generators must certify that they have a program in place to reduce the volume and toxicity of the hazardous waste they generate; small quantity generators must certify that they have made a good faith effort to minimize their waste generation. Generators should include the following six basic elements in their waste minimization program: top management support, characterization of waste generation and waste management costs, periodic waste minimization assessments, appropriate cost allocation, encouragement of technology transfer, and program implementation and evaluation (58 FR 31114, May 28, 1993).

    Additional guidance on the generator's waste minimization certification on the manifest is available in the following documents on RCRA Online database:

    • Monthly Call Center Report Question, June 1997 (RCRA Online #12932).

Personnel Training

  • 1. What Resource Conservation and Recovery Act (RCRA) training requirements apply to hazardous waste generators? Are all staff members required to comply with these training requirements?

    The amount and/or type of training required for hazardous waste generators is dependent on the amount of hazardous waste generated by the facility in a calendar month. Large quantity generators (LQGs)—those who generate more than 1,000 kg/month of hazardous waste (or more than 1 kg/month of acutely hazardous waste)—must comply with the emergency preparedness and personnel training requirements in section 262.17(a)(7). The generator's training program must be "designed to ensure that facility personnel are able to respond effectively to emergencies by familiarizing them with emergency procedures, emergency equipment, and emergency systems..." These requirements are intended to ensure that personnel are adequately prepared to properly handle the types of hazardous wastes that are managed at the facility and to respond to any emergencies that are likely to arise. LQG personnel must also take part in an annual review, and the facility must document that all hazardous waste personnel have met all applicable training requirements.

    Small quantity generators (SQGs)—those who generate greater than 100 kg but less than 1,000 kg/month of hazardous waste—must comply with the emergency preparedness and personnel training requirements in section 262.16(b)(9). These standards state that, “the small quantity generator must ensure that all employees are thoroughly familiar with proper waste handling and emergency procedures, relevant to their responsibilities during normal facility operations and emergencies.”

    The training requirements do not apply to generators of less than 100 kg/month (e.g., very small quantity generators (VSQGs)) or to personnel who work only in satellite accumulation areas. It is a best practice, however, to ensure that all workers that are handling hazardous waste have a knowledge of the relevant hazards and appropriate requirements and are prepared to respond to any emergency situation appropriately.

    In addition, not all personnel at a given location need to meet the RCRA training standards (e.g., secretaries, fulfillment staff). Instead, the RCRA training requirements apply to hazardous waste personnel working in central accumulation areas.

    Note that the term “personnel” may include contractors since they are held to the same standards as non-contract facility personnel. Additional clarification on the definition of facility personnel is available in the following guidance document: Monthly Call Center Report Question, March 1998 (RCRA Online #14180). Most states are authorized to implement the RCRA regulations and they may also have more stringent regulations. Therefore, you should contact your state agency to determine if there are any additional state-specific training requirements for generator facility personnel. Authorized states may also require training for VSQGs. State web sites can be found on this web page.

    Additional guidance on the training requirements for hazardous waste generators is available in the following memos in the RCRA Online database:

    • Memo, Springer to Sherman, November 19, 2003 (RCRA Online #14687).
    • Memo, Cotsworth to Tierney, June 10, 1997 (RCRA Online #14286).
    • Memo, Denit to Bell, October 7, 1993 (RCRA Online #11779).
    • Memo, Lowrance to D'Aloia, May 9, 1989 (RCRA Online #11429).
  • 3. What documentation must a generator maintain to demonstrate compliance with the Resource Conservation and Recovery Act (RCRA) training requirements?

    A large quantity generator must maintain training-related documents and records at the facility (section 262.17(a)(7)(iv)). The records must include the following:

    • a job title for each position at the facility related to hazardous waste and the name of the employee filling that position (section 262.17(a)(7)(iv)(A));
    • a written job description for each position at the facility related to hazardous waste (section 262.17(a)(7)(iv)(B));
    • a written description of the type and amount of both introductory and continuing training that will be given to each person filling such a position (section 262.17(a)(7)(iv)(C)); and
    • records that document that the training or job experience required has been given to, and completed by, facility personnel (section 262.17(a)(7)(iv)(D)).

    The generator must maintain training records on current personnel until closure of the facility and former employees for three years (section 262.17(a)(7)(v)). Additional clarification is available in the following guidance document in the RCRA Online database: Monthly Call Center Report Question, December 1984 (RCRA Online #12341).

    Small quantity generators (SQGs) are also subject to training regulations. SQGs must ensure that all personnel that manage hazardous waste are thoroughly familiar with the proper waste handling and emergency procedures relevant to their responsibilities during normal facility operations and emergencies. There is no specific recordkeeping requirement attached to the SQG training regulations (section 262.16(b)(9)(iii)).

  • 4. What training is required for the person who signs the manifest certification?

    The training requirements for the person who signs the manifest depend on that person’s responsibilities within the hazardous waste generation process. While any waste handler and broker can prepare a manifest "on behalf of" a generator (i.e., complete Items 1-14 on the form), the authority to sign manifests is more limited.

    Manifests prepared by others for a generator customer can be signed by the generator, or by the agent (e.g., a contractor) of the generator operating on site and performing generator responsibilities at the site for the generator, or by an offeror. An offeror is a person, typically the representative of the initial transporter, who performs the pre-transportation functions (e.g., packaging waste in containers, preparing and affixing labels, preparing the manifest) on site, and has personal knowledge of the facts involved with the preparation of the waste for transportation. In these cases, an offeror can sign the generator/offeror certification on the manifest on behalf of the generator because the offeror can certify that the waste materials have been properly described and the shipment is in proper condition for transportation.

    To reiterate, both generators (and their agents) and offerors can sign the manifest. While there are no training requirements under part 262 for offerors, EPA recommends that they have sufficient training to be able to act appropriately in the event of an emergency. Generators and/or their agents are required to comply with the training requirements in part 262. The specific training requirements depend on the generator's category. Large quantity generators (LQGs) must comply with the emergency preparedness and personnel training requirements in 40 CFR section 262.17(a)(7). Small quantity generators (SQGs) must comply with the requirements in section 262.16(b)(9)(iii). Very small quantity generators (VSQGs) are not required to comply with training requirements.

    In addition, the Department of Transportation (DOT) also regulates shipments of hazardous waste. Therefore, facility personnel are also subject to all applicable DOT training requirements. The training requirements for hazardous materials employees are defined in the DOT Hazardous Materials Regulations at 49 CFR part 172 subpart H. DOT requires that the person signing the manifest have "first-hand knowledge" of the information listed on the manifest and the regulations that apply to the waste. The generator must certify that the materials are properly classified, described, packaged, marked and labeled, and in proper condition for transporting (Memo, Springer to Sherman, November 19, 2003 (RCRA Online #14687 (3 pp, 15 K, About PDF))). The generator certification is required by RCRA (section 262.23(a)) and DOT.

Satellite Accumulation Areas

  • 1. What regulations apply to generators of hazardous waste managed at satellite accumulation areas?

    Hazardous waste generators are allowed, but not required, to accumulate small amounts of hazardous waste in locations at or near any points of generation (section 262.15) that are under the control of the person operating the process that generates the hazardous waste (section 262.15). A generator may accumulate up to fifty-five gallons of hazardous waste and/or one quart of liquid acute hazardous waste or one (1) kg of solid acute hazardous waste at each satellite accumulation area (SAA) . The preamble of the Hazardous Waste Generator Improvements rule (81 FR 85732) includes a discussion about and examples of what EPA means by “under the control of the operator.” For example, EPA would consider waste to be “under the control of the operator” if the operator controls access to an area, building, or room in which the SAA is located, such as with entry by access card, key or lock box. Another example is if the operator accumulates waste in a locked cabinet and controlled access to the key, even if the cabinet is stored inside a room to which access is not controlled. See pages 85767–8 of the preamble for the full discussion.

    Limited standards, such as labeling, keeping the containers closed, and maintaining containers in good condition, apply to SAAs. Once the generator exceeds the volume limits, the excess waste must be dated and moved within three consecutive calendar days to the central accumulation area (CAA). At the CAA, the waste must be managed in accordance with the more comprehensive hazardous waste accumulation standards in section 262.16(b) for SQGs or section 262.17(a) for LQGs.

    Additional guidance on hazardous waste accumulation in SAAs is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

  • 3. What are the container requirements for generators accumulating hazardous waste in satellite accumulation areas (SAAs)?

    Generators accumulating hazardous waste in satellite accumulation areas must comply with the container standards in section 262.15. Specifically, the containers must be in good condition, compatible with the hazardous waste, and closed during accumulation, with limited exceptions. Generators must also mark their containers in satellite accumulation areas with words that identify the hazards of the contents of the containers and the words "Hazardous Waste" (section 262.15(a)(5)). Generators must comply with the accumulation limits in SAAs and remove the excess from the SAA within three consecutive calendar days.

    Note: On November 28, 2016, EPA published the Hazardous Waste Generator Improvements Final Rule, which revised the labeling requirements for waste accumulated in SAAs.

    The Hazardous Waste Generator Improvements Final Rule is effective as of May 30, 2017; however, implementation in a particular state depends on whether the state has adopted the rule. Information about whether this revision is effective in any given state is best obtained from the state hazardous waste program. A list of state hazardous waste programs is available here.

  • 4. Can small quantity generators establish satellite accumulation areas (SAAs) according to section 262.15 for their hazardous waste?

    Yes. Both large quantity generators (LQGs) and small quantity generators (SQGs) may accumulate hazardous waste in SAAs, provided it is managed in accordance with all the provisions of 40 CFR section 262.15. If an SQG or LQG accumulates more than 55 gallons of non-hazardous waste, and/or 1 quart of liquid acute hazardous waste or 1 kg of solid acute hazardous waste at an SAA, the excess must be removed within three consecutive calendar days and shipped either off site to a designated facility, taken to an on-site treatment, storage and disposal facility (TSDF), or taken to an on-site central accumulation area. Generators also have the option of converting the SAA to a CAA within three days of exceeding the specified limits by complying with the CAA regulations in section 262.16(b) for SQGs, or section 262.17(a) for LQGs.

  • 5. When a facility has equipment that discharges hazardous wastes to attached containers, do the containers that collect such wastes have to be in compliance with the satellite accumulation area (SAA) regulations?

    Yes. Even if the discharging unit is not regulated under the Resource Conservation and Recovery Act (RCRA), the attached containers that collect hazardous wastes from such equipment must comply with the SAA regulations if those containers collect wastes that are listed or characteristic hazardous wastes. Waste containers in SAAs must meet the following conditions: be in good condition (section 262.15(a)(1)), be compatible with their contents (section 262.15(a)(2)), and be labeled with words that indicate the hazards of the contents and the words "hazardous waste" (section 262.15(a)(5)). In addition, the containers in SAAs must be closed, except when adding or removing hazardous waste or under certain conditions when temporary venting is necessary (section 262.15(a)(4)). The container(s) attached to such equipment is a point of generation. It is possible for there to be multiple pieces of equipment within one SAA, and thus multiple points of generation within a single SAA, provided all the pieces of equipment are "at or near" each other and "under the control of the operator of the process generating the waste." Under this scenario, the total amount of hazardous waste in the SAA would be limited to 55 gallons (and/or 1 quart of liquid acute hazardous waste or 1 kg of solid acute hazardous waste) and a generator would be allowed to consolidate like hazardous wastes from multiple discharging units.

Closure

  • 1. What are the closure standards for hazardous waste management units at generator facilities?

    Large quantity generators (LQGs) must comply with the general closure provisions in section 262.17(a)(8). LQGs storing waste in tanks, in containers, on drip pads, or in containment buildings are subject to the unit specific closure requirements. Although small quantity generators (SQG) cannot leave hazardous waste behind when the generator site closes, there are no specific closure requirements for SQGs , except that SQGs managing waste in tanks must remove all hazardous waste from such tanks, discharge control equipment, and discharge confinement structures upon closure (section 262.16(b)(3)(E)(vi)). Additional guidance on generator closure is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

Very Small Quantity Generators

  • 4. Are very small quantity generators (VSQGs) exempt from the used oil management standards in Part 279?

    The part 279 standards do not contain an exemption for any class of generators based on used oil generation rate. As a result, all used oil generators producing used oil through commercial or industrial operations and vehicle services are subject to the same uniform standards (57 FR 41566, 41584; September 10, 1992). Only the individuals listed in section 279.20(a)(1) through (4) are exempt from the part 279 generator requirements.

  • 6. May a very small quantity generator (VSQG) treat hazardous waste on site without a permit?

    Very small quantity generators (VSQGs) may treat hazardous waste on site without a permit provided they meet one of the conditions in 40 CFR section 262.14(a)(5)(iii–vii) or (xi). If a VSQG is not one of these types of facilities, it must have a permit under part 270, or operate under interim status under parts 270 and 265 before treating or disposing of waste on site. (See 61 FR 34252, July 1, 1996). However, federal regulations allow states to adopt more stringent regulations if they choose, and some states have chosen not to exempt VSQGs from many of the hazardous waste requirements. Therefore, VSQGs should contact their state solid/hazardous waste program offices to determine regulations for VSQGs. Additional guidance regarding VSQG requirements is available in the following documents in the Resource Conservation and Recovery Act (RCRA) Online database:

    • Monthly Call Center Report Question, January 2003 (RCRA Online #14662).
    • Memo, Shapiro to Kim, May 1, 1996 (RCRA Online #14030).

Recent Rule Changes

  • 1. What revisions did EPA finalize in the 2016 Hazardous Waste Generator Improvements Rule? When will the rule become effective and how will it be affected by state authorization?

    On November 28, 2016, EPA published the Hazardous Waste Generator Improvements Final Rule. This rule revises the hazardous waste generator regulations to make the rules easier to understand, facilitate better compliance, provide greater flexibility in how hazardous waste is managed, and close important gaps in the regulations. Two key provisions where EPA is finalizing flexibility are:

    1. Allowing a hazardous waste generator to avoid increased burden of a higher generator status when generating episodic waste provided the episodic waste is properly managed and
    2. Allowing a very small quantity generator (VSQG) to send its hazardous waste to a large quantity generator under control of the same person.

    The rule also improves hazardous waste risk communication and emergency management requirements and provides a number of clarifications without increasing burden, including a reorganization of the hazardous waste generator regulations so that all of the generator regulations are in one place.

    This final rule is effective federally as of May 30, 2017. This rule finalizes regulations that amend certain sections of the hazardous waste generator regulations in 40 CFR parts 260 through 265, 268, 270, 273, and 279. These regulations were promulgated under non-Hazardous and Solid Waste Amendment (HSWA) of 1984 authority. Thus, the standards will be applicable on the effective date only in those states that do not have final authorization of their base Resource Conservation and Recovery Act (RCRA) programs. Moreover, authorized states are required to modify their programs only when EPA promulgates federal regulations that are more stringent or broader in scope than the authorized state regulations. For those changes that are less stringent, states are not required to modify their programs. A discussion of the revisions made by this rule and whether they are more or less stringent is available on page 85801 of the final rule. Information about a state’s adoption status and their plan to incorporate these revisions is available from the state hazardous waste program. A list of state hazardous waste programs is available.
