05/01/2006Environmental Fact Sheet: EPA Proposes Tailored RCRA Requirements for Academic LaboratoriesPublication
 Description: This fact sheet discusses the May 23, 2006, Academic Labs proposed rule (71 FR 29712), which is intended to tailor RCRA regulations to the unique environment of an academic laboratory. This alternative set of regulations would provide academic laboratories with increased flexibility, helping them ensure that the waste they generate is safely managed.
 
03/17/2004FREQUENTLY ASKED QUESTIONS ABOUT SATELLITE ACCUMULATION AREASMemo
 Description: Summary of generator accumulation regulations. Both LQGs and SQGs may establish satellite accumulation areas (SAA). Waste in excess of 55 gallons or 1 quart of acute hazardous waste must be removed within three days. When a generator exceeds 55 gallons or 1 quart acute hazardous waste, the container must be dated. The generator must date container again when it is moved to central accumulation area. Three days means three consecutive days. There is no federal requirement that full containers of hazardous waste be removed from an SAA within three days of being filled. Generators may transfer hazardous waste between containers to facilitate storage, transportation, or treatment. Containers in SAAs do not have to comply with the air emission standards of Part 265 Subparts AA, BB, and CC. Inspections of SAAs are not required if SAA meets 262.34(c) requirements. Personnel working in SAAs not required to have training. It is permissible to have more than one waste in an SAA and more than one container of hazardous waste in an SAA. The regulations do not limit the total number of SAAs at a generator facility. Generators may not move hazardous wastes between SAAs. A single SAA may have multiple points of generation. Generators must include all hazardous waste in their SAAs in monthly quantities for determining their generator status. Containers attached to equipment discharging hazardous waste must comply with SAA regulations and is a point of generation. Small containers (vials or tubes) may be placed in properly labeled larger containers. (SEE ALSO: 75 FR 12989, 12994; March 18, 2010)
 
01/01/2004Manejando Sus Residuos Peligrosos: Una Guía para Empresas Pequeñas (Spanish - Managing Your Hazardous Waste: A Guide for Small Businesses)Publication
 Description: This publication is the Spanish translation of Managing Your Hazardous Waste: A Guide for Small Businesses (EPA530-K-01-005). The manual helps small businesses determine whether they generate hazardous waste and provides comprehensive information on how to comply with the federal hazardous waste regulations for small quantity generators. It explains how to obtain an EPA identification number, manage hazardous waste on site, ship hazardous waste off site, comply with land disposal restrictions, and conduct good housekeeping.
 
08/01/2003SMALL QUANTITY GENERATOR TREATMENT IN TANKSQuestion & Answer
 Description: Hazardous waste generators may treat waste on site in accumulation tanks or containers without a permit or interim status provided that they comply with applicable provisions in 40 CFR 262.34 and the treatment is not thermal treatment (SEE ALSO: 56 FR 10146, 10168; 3/24/86). A small quantity generator (SQG) performing on-site treatment in a tank only follows the special standards in 265.201 and not all of the Part 265, Subpart J requirements. Standards in 265.201 supplant Subpart J requirements for SQGs rather than supplement them. Part 265, Subparts I and J, including SQG tank standards in 265.201, apply whether a unit is used for treatment or accumulation. Authorized states can have more stringent requirements.
 
01/01/2003FREQUENTLY ASKED QUESTIONS ON GENERATOR TREATMENTQuestion & Answer
 Description: Small quantity generators (SQGs) and large quantity generators (LQGs) may treat hazardous waste on site without a permit provided they comply with 262.34 and conduct no thermal treatment. Conditionally exempt small quantity generators (CESQGs) may treat hazardous waste on site without a permit provided they meet one of the conditions in 261.5(g)(3)(iii) through (vii). No generator may conduct thermal treatment without a permit. SQGs cannot treat in containment buildings or on drip pads and continue to operate under the reduced 262.34(d) standards. Only SQGs that operate under LQG standards may use these units. State implementing agencies may have more stringent rules regarding generator treatment.
 
12/01/2001Managing Your Hazardous Waste: A Guide for Small BusinessesPublication
 Description: The manual helps small businesses determine whether they generate hazardous waste and provides comprehensive information on how to comply with the federal hazardous waste regulations for small quantity generators. It explains how to obtain an EPA identification number, manage hazardous waste on site, ship hazardous waste off site, comply with land disposal restrictions, and conduct good housekeeping.
 
02/01/1999MOVEMENT OF WASTE BETWEEN SATELLITE ACCUMULATION AREASQuestion & Answer
 Description: Large quantity generators (LQG) and small quantity generators (SQG) with multiple satellite accumulation areas cannot move wastes between satellite accumulation areas. Waste that leaves a satellite accumulation area should be destined for an accumulation area which is fully regulated under 262.34(a) or (d), or Parts 264 or 265.
 
12/01/1998GENERATOR CLOSURE REQUIREMENTSMemo
 Description: Large quantity generator (LQG) closure standards require the minimization of need for further maintenance, the minimization or elimination of post-closure escape of hazardous waste or constituents, and decontamination or removal of all contaminated equipment, structures, and soils. LQGs storing or treating waste in tanks, drip pads, or containment buildings are also subject to unit-specific closure standards. Small quantity generators (SQG) managing waste in tanks must remove all hazardous waste, discharge control equipment, and discharge confinement structures. Conditionally exempt small quantity generators (CESQG) do not have closure requirements.
 
12/01/1997Waste Minimization: Relief from RCRA Large Quantity Generator Status, 105th Airlift Wing, New York Air National GuardPublication
 Description: This fact sheet details the success of the waste minimization program for the New York Air National Guard, which was able to move from large quantity generator status to small quantity generator status.
 
09/01/1996TOLLING AGREEMENTS AND EXPORTSQuestion & Answer
 Description: Export standards apply only to primary exporters of waste. The primary exporter is an exporter that requires a manifest. Small quantity generators (SQGs) with contractual reclamation agreements do not require a manifest. SQGs shipping waste under a reclamation agreement are not subject to export requirements because they are not a primary exporter.
 
05/01/1996INTERPRETATION OF GENERATOR REQUIREMENTS AS APPLIED TO VARIOUS ON-SITE AND OFF-SITE SCENARIOSMemo
 Description: Provides a clarification of the terms on-site, facility, installation, and individual generation site. Contiguous properties owned by different persons require separate identification numbers. Manifests are required for all off-site shipments of waste, even if both properties belong to the same generator (SUPERSEDED: manifest exemption for shipments along the border of contiguous properties; 62 FR 6622; 2/12/97). No manifest is required to ship hazardous waste between two properties under the same ownership that are located at opposite corners of an intersection. Large quantity generator (LQG) and small quantity generator (SQG) waste must be sent to a designated facility. No final interpretation exists on whether conditionally exempt small quantity generator (CESQG) waste sent to an intermediate location for consolidation loses its exemption. Waste in transportation may be consolidated at transfer facilities. The emergency response exemption from permitting applies to immediate response only. Hazardous waste generated as the result of discharge may be accumulated for 90 days under Section 262.34.
 
04/01/1996FREQUENTLY ASKED QUESTIONS ON HAZARDOUS WASTE GENERATOR REQUIREMENTSQuestion & Answer

09/08/1986REGULATORY OBLIGATIONS OF PRINTERS WHO USE RECYCLABLE RAGS AND WIPERSMemo
 Description: Generator status is determined by the total of the hazardous waste generated in a calendar month. Waste identification for solvent-contaminated rags and shop towels is under review for petition (SEE ALO: RPC# 2/14/94-01). SQG solvent rags from the printing industry may be managed under a tolling agreement. A printer shipping hazardous rags to an industrial laundry may qualify for the manifest exemption under 262.20(e) if the printer is a SQG and all conditions of the exemption are met.
 
07/01/1986INTERIM STATUS FOR RECEIVING SQG WASTEQuestion & Answer
 Description: A facility managing SQG wastes on or before 9/22/86, qualifies for interim status because it is in existence. If a facility obtains interim status for managing SQG waste, and then wants to expand to also manage LQG waste, the owner or operator must submit a revised Part A under changes during interim status.
 
04/28/1986WASTE MINIMIZATION CERTIFICATION REQUIREMENTSMemo
 Description: A discussion of a proposal to extend waste minimization certification requirement to small quantity generators. Only one signature is required for two parts of the certification. From an enforcement perspective, EPA is primarily concerned with the compliance with the certification signatory requirement. A generator should make a good faith effort to minimize the amount of waste generated (3002(b)). Judgments made by the generator for purposes of a waste minimization certification are not subject to external regulatory action.
 
04/01/1986SMALL QUANTITY GENERATOR (SQG) ACCUMULATIONQuestion & Answer
 Description: A generator must count all waste on-site when determining if the quantity of waste on-site exceeds 6000 kg, including wastes produced in one month as SQG which are in one area and wastes produced in another month as LQG which are in separate area.

 Description: Once an SQG limit is exceeded, any waste generated and accumulated is also subject to Part 262 regulation, including labeling (SUPERSEDED: see 51 FR 10175; 3/24/86, current 261.5).
 
06/01/1984EPISODIC GENERATOR AND PERSONNEL TRAININGQuestion & Answer
 Description: A small quantity generator under 261.5 who episodically becomes a large quantity generator needs to only comply with personnel training requirements when he is subject to 262.34 (SEE ALSO: current 261.5 and 262.34 for revised generator categories).
 
03/01/1984LAND DISPOSING SMALL QUANTITY GENERATOR WASTEQuestion & Answer
 Description: The February 15, 1984 advance notice of proposed rulemaking (49 FR 5854) does not ban land disposal of small quantity generator waste (SEE ALSO: 268.1(e)(1), 262.34(d)(4), RPC# 5/9/94-01).
 
10/21/1983LEACHATE FROM A MUNICIPAL LANDFILL, REGULATION OFMemo
 Description: Leachate from municipal landfills must be handled as hazardous if it is characteristic. The landfill is the generator of the waste. Nonhazardous leachate can be recycled into the landfill. Hazardous leachate must go to a TSDF or POTW unless the landfill is an exempt small quantity generator (SUPERSEDED: for landfill leachate recirculation, see 258.28) (SEE ALSO: 261.31 (F039 listing), 261.5, 262.34).
 
02/01/1982DEFINITION OF LICENSED FACILITYQuestion & Answer
 Description: EPA intended 261.5(g)(3)(iv) to apply to states with programs to permit or license facilities handling only SQG waste. In states without a formal program, registered includes facilities that have informed state or local government of their activities (SUPERSEDED: the SQG designation was replaced with the CESQG designation for the purposes of 261.5, see 51 FR 10174; 3/24/86).
 
11/17/1980RAILROAD TIES AS HAZARDOUS WASTES UNDER THE MIXTURE RULE, SMALL QUANTITY GENERATORMemo
 Description: Products that contain listed CCPs, such as railroad ties or asbestos insulation, are not listed CCPs when they are discarded. The mixture rule applies to CCPs being mixed with solid wastes. The point of generation for a CCP is “instantly when the act of discarding takes place.” Incorporating CCPs like creosote and asbestos into a product is not mixing with solid waste. A company with several operations on one site is a single generator. Even if each operation qualified as an SQG, the total site waste production may make all operations LQGs. If a facility is an LQG, all wastes must be handled as LQG waste, even wastes that are produced in small quantities or intermittently (SUPERSEDED: see current 261.5, 262.34(d)).
