04/17/1997CLARIFICATION ON USE OF FATE AND TRANSPORT MODELING DURING RCRA CLOSURE AND PUBLIC PARTICIPATION DURING RCRA CORRECTIVE ACTIONMemo
 Description: The Agency allows the appropriate use of fate and transport modeling to demonstrate, under clean closure, that materials contaminated with waste that are not removed do not present unacceptable risks. The use of modeling to make demonstration does not affect the requirements for removal of all wastes (SEE ALSO: RPC# 9/24/96-01). EPA's commitment to public participation is the same whether corrective action is implemented in the context of a RCRA permit or an enforcement order. EPA expects that non-RCRA cleanups will provide an appropriate level of public participation. The public has an opportunity to review and comment on whether it is appropriate for the Agency to defer RCRA corrective action to a non-RCRA program in certain instances.
 
03/20/1997APPLICABILITY OF LDR TO LAND TREATMENT OF HAZARDOUS WASTEMemo
 Description: Any hazardous waste that is subject to LDR must meet applicable treatment standards or qualify for a variance before it can be applied in a land treatment unit. Untreated waste may be placed in a land treatment unit if the unit has received a no-migration variance. Currently, only one no-migration variance has been granted to a land treatment facility. Permits that predate the LDR requirements do not shield the permittee or the facility from any of the LDR requirements.
 
02/01/1997DELAY OF CLOSUREQuestion & Answer
 Description: Owners and operators of hazardous waste surface impoundments, landfills, and land treatment units can delay the closure timetable beyond the 90-day period and allow the units to accept nonhazardous waste, if the units meet the conditions of Sections 264.113(d)/265.113(d). Owners or operators of tanks, containers, waste piles, and incinerators are not allowed to delay closure. These units must comply with all applicable closure standards before being able to accept nonhazardous waste.
 
04/24/1996PERFORMANCE AND SAFE APPLICABILITY OF COLD-MIX TECHNOLOGIES AND BIOREMEDIATION FOR PETROLEUM-CONTAMINATED SITESMemo
 Description: Discusses the appropriateness of solidification and stabilization technologies for the treatment of organics. Stabilization/solidification technologies are not considered best demonstrated available technology (BDAT) for petroleum wastes. Volatilization can occur during certain stabilization/ solidification processes. Discusses bioremediation technologies (including land treatment, biopiles, and bioventing) and degradation rates.
 
02/20/1996CLARIFICATION OF RCRA CORRECTIVE ACTION PROGRAM WITH REGARD TO TSD UNITSMemo
 Description: RCRA regulated units (surface impoundments, waste piles, land treatment units, and landfills) are solid waste management units (SWMUs). SWMUs are subject to RCRA corrective action authority (i.e., Sections 3004(u) or 3008(h)). Discusses integrated implementation of corrective action for releases to groundwater and other media from regulated units (SEE ALSO: Section 264.90(f) and 63 FR 56710; 10/22/98)). Dual authority is required when conducting cleanup at a regulated unit in a state authorized for RCRA groundwater requirements but not for corrective action. Changes necessary to comply with a corrective action order are exempt from the reconstruction limit. Closure need not be delayed to perform corrective action. EPA encourages coordination between closure and corrective action activities.
 
12/10/1991NO-MIGRATION PETITION FOR KOCH REFINING, TXMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to the presence of hazardous constituents below the treatment zone, in soil-pore liquid, and in groundwater at the land treatment facility.
 
05/29/1991NO-MIGRATION PETITION FOR CONOCO, MTMemo
 Description: The determination of environmental threats from land treatment facilities seeking land disposal restrictions (LDR) no-migration petitions are based on sensitivity of environmental receptors, presence of exposure pathways to receptors, and exposure to contaminants at hazardous levels. Discussion of criteria required to properly assess such threats.
 
05/02/1991CLOSURE STANDARDS FOR HAZARDOUS WASTE LAND TREATMENT UNITSMemo
 Description: Soil sampling is usually required during land treatment unit closure and post-closure as part of the unsaturated zone monitoring. If the treatment unit is removed as a part of clean-closure, the soil-core monitoring may be suspended at the completion of the closure period. Discusses guidance on intervals for, and duration of, soil sampling during closure and post-closure. There is no EPA-approved methods for determining degradation rates. Closure of a land treatment unit may take up to 360 days. Discussion of closure and post-closure standards for a land treatment units when migration of hazardous constituents has occurred. Discussion of closure standards when groundwater is contaminated at levels below alternate concentration levels specified in a facility permit. The post-closure period for a land treatment unit cannot be terminated until owner or operator has successfully demonstrates that all groundwater at the site is safe for all potential receptors. Discuses addressing migration of constituents of concern outside of the treatment zone during closure versus under corrective action. There are no regulatory provisions requiring corrective action when migratory constituent concentrations exceed regulatory levels of concern in groundwater at an interim status land treatment facility (3008(h)). Discussion of when closure is considered complete.
 
05/01/1991NO-MIGRATION PETITION FOR ROBINSON, ILMemo
 Description: Guidance on the revision of an existing petition or withdrawal and resubmission of a new petition after EPA’s denial of a land disposal restrictions (LDR) no-migration petition for a land treatment unit and surface impoundment.
 
04/22/1991NO-MIGRATION PETITION FOR ATLANTIC REFINING & MARKETING, PAMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to releases from the land treatment facility in excess of health based levels, inadequate soil and groundwater monitoring system, noncompliance with other regulatory requirements.
 
02/05/1991NO-MIGRATION PETITION FOR KERR-MCGEE REFINING, OKMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to the presence of hazardous constituents below land treatment facility, inadequate groundwater monitoring system, and failure to maintain minimum separation between high water table and bottom treatment zone.
 
01/17/1991NO-MIGRATION PETITION FOR SUN REFINING, OKMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to hazardous constituents below treatment zone, inadequate groundwater monitoring system, inability to maintain minimum distance between treatment zone and high water table, and failure to demonstrate no constituents will migrate beyond the land treatment unit.
 
01/03/1991NO-MIGRATION PETITION FOR KOCH'S REFINING, TXMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to the presence of hazardous constituents below the treatment zone and in the groundwater from the land treatment unit.
 
11/08/1990NO-MIGRATION PETITION FOR AMOCO REFINERYMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to an inadequate groundwater monitoring system and the presence of hazardous constituents below the treatment zone at land treatment facility.
 
11/08/1990NO-MIGRATION PETITION FOR SINCLAIR OIL, OKMemo
 Description: Discusses EPA’s dismissal of a land disposal restrictions (LDR) no-migration petition due to failure to have a monitoring plan that detects migration from land treatment facility at the earliest practicable time and the presence of hazardous constituents in the groundwater.
 
11/07/1990NO-MIGRATION PETITION FOR SHELL OIL, WAMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to the presence of hazardous constituents below land treatment zone, and failure to have a monitoring plan that detects migration at the earliest practicable time.

10/24/1990NO-MIGRATION PETITION FOR ARCO PRODUCTS, WAMemo
 Description: Discusses EPA’s denial of a land disposal restrictions (LDR) no-migration petition due to inadequate groundwater monitoring system, excessive hazardous constituent release to air, presence of hazardous constituents below the land treatment zone, and inability to maintain minimum separation between treatment zone and groundwater table.
 
09/05/1990APPLICABILITY OF PERMITTING TO MOVEMENT OF HAZARDOUS WASTE THAT DOES NOT CONSTITUTE LAND DISPOSAL Memo
 Description: Land disposal includes movement of hazardous waste (HW) into a unit, but not movement within the unit. Movement within the unit does not require a permit. Movement of HW within a unit that is associated with land treatment may require a treatment permit.
 
06/04/1990REGULATORY INTERPRETATION OF OBJECTION TO CLEAN-CLOSURE EQUIVALENCY PETITION FOR STEEL ABRASIVES, INC.Memo
 Description: All landfills, surface impoundments, waste piles, and land treatment units that received waste after July 26, 1982 are subject to post-closure permitting and Part 264 Subpart F standards unless the owner demonstrates that closure under the previous Part 265 standards met Part 264 closure by removal standards (SUPERSEDED: See 63 FR 56711; October 22, 1998). Under RCRA 3005(i), EPA has the authority to revisit interim status clean closures and require post-closure permits if closure does not meet closure by removal standards of Part 264. In order to demonstrate clean closure, an owner generally should remove “hot spots” of contamination.
 
04/27/1990DEGRADATION, TRANSFORMATION OR IMMOBILIZATION IN TREATMENT ZONEMemo
 Description: The land treatment facility requirement for complete degradation, transformation, or immobilization in the treatment zone means that there will be no statistically significant release to the environment from the treatment zone.
 
02/22/1990D001 CHARACTERISTIC WASTES - LAND DISPOSAL RESTRICTIONSMemo
 Description: Waste cannot be disposed of unless treated to land disposal restrictions (LDR) treatment standards, disposed in no-migration unit, or subject to exemption or variance from treatment standards. D001 ignitable waste must be treated to treatment standard before disposal. There are special requirements for ignitable wastes placed in a surface impoundment, landfill, waste pile, and land treatment unit.
 
05/16/1989DELAY OF CLOSURE PERIOD FOR HWM FACILITIESMemo
 Description: Under limited circumstances, landfills, surface impoundments, and land treatment units may remain open after the final receipt of hazardous waste in order to receive nonhazardous waste.
 
03/30/1989CERTIFICATION PROCESS ON BIOTECHNOLOGICAL METHODS FOR REMEDIATION OF INDUSTRIAL FACILITIESMemo
 Description: EPA does not certify biotreatment technologies for the remediation of soil and groundwater, but will assist with determining the applicability of biotreatment technologies.
 
03/23/1989POSTPONEMENT OF A LAND TREATMENT DEMONSTRATION FOR NAVAJO REFINING CO., ARTESIA, NMMemo
 Description: A permit can be appealed for reasons other than those received during comment. The effective date of a treatment demonstration does not affect the effective date of the permit. EPA can require a treatment demonstration through the omnibus provision (3005(c)(3)). Addresses the regulatory status of a facility with a two-phase permit, and the applicability of public notice and comment to changes in a land treatment demonstration start date .
 
05/27/1988SOIL BACKGROUND LEVELS AS CLEAN CLOSURE STANDARDS, USE OFMemo
 Description: Clean closure levels for surface impoundments, waste piles, and land treatment units must be based on EPA-recommended exposure levels or factors that have undergone peer review by EPA. Where no health-based levels exist, clean closure levels are based on background or exposure levels submitted by the owner based on toxicity data. Includes recommendations for clean closure levels for lead and cadmium. Lead background levels should be established by taking soil samples at an uncontaminated area of the facility or by using published literature data on lead levels in similar soils (SUPERSEDED: see RPC# 5/7/90-01).
 
05/01/1988LAND DISPOSAL RESTRICTIONS - DISPOSAL OF WASTES GRANTED A VARIANCEQuestion & Answer
 Description: Restricted wastes that are granted a capacity variance may be disposed of in landfills or surface impoundments only if the facility is in compliance with the minimum technological requirements (MTR). These wastes may also be disposed of in land treatment facilities that are not in compliance with MTR (SUPERSEDED: 268.8 removed, see 61 FR 15599; 4/8/96).
 
04/11/1988INITIAL SOIL SURFACE TERM DEFINED IN LAND TREATMENT REGULATIONSMemo
 Description: The initial soil surface means the topographic level that was in existence when waste was first applied to a land treatment unit. Built-up material at a land treatment unit must not be excessive waste overloading the treatment system.
 
03/30/1988SUMMARY OF PERMIT ASSISTANCE TEAM (PAT) COMMENTSMemo
 Description: Samples taken from turbid groundwater may not be valid. Proper well development requires that wells be clay and silt free. Discusses the use of polyvinyl chloride (PVC) in well construction, the calculation of purge volume, and Part 264, Appendix IX. An accelerated groundwater monitoring schedule can be used to bring a facility into compliance. The maintenance of a groundwater monitoring network may include the redevelopment of a well. Well maintenance should be included as a permit condition. Replacement units (e.g. landfills and surface impoundments) must be retrofitted to meet the minimum technological requirements. If a proposed alternative to a double liner does not meet the requirements of 264.221(c), the location characteristics or operating practices must compensate for the deficiency. A redundant flexible membrane bottom liner may be equivalent to the 3004(o)(5)(B) interim statutory design, thus meeting the 3004(o)(1) minimum technological requirements. Addresses the use of the Hydrologic Evaluation of Landfill Performance (HELP) model v. Moore’s Equation for calculating leachate volume when designing a collection system, the proposed modifications to the cap design to reduce erosion potential, and the use of a test plot to support alternative landfill design cover. A high-density polyethylene liner must be supported by a stable base. An owner of a petroleum refinery undertaking a land treatment demonstration must fully characterize the waste, including addressing the Skinner List constituents in the waste analysis plan. A properly conducted land treatment demonstration should include an evaluation of the waste degradation, transformation, and immobilization, as well as a toxicity study. A land treatment unit cannot accept sludges containing high concentrations of water if the soil moisture conditions cause saturation of the unit. Discusses the selection of principal hazardous constituents for a land treatment unit. An owner of a land treatment unit who has not demonstrated satisfactory treatment of hazardous constituents may need to close the unit. Addresses the presence of a high water table at a land treatment unit and the possible responses. An owner of an existing interim status land treatment unit may be eligible for an immediate full-scale permit if the land treatment demonstration addresses all of the necessary requirements. In states that are authorized for the RCRA base program but not for the HSWA provisions, construction cannot begin at a new facility until both the state and EPA permits are issued. The land disposal restrictions (LDR) program is a self-implementing portion of HSWA, superseding the permit as a shield provision. Permit content should be edited for applicability, importance, clarity, and precision prior to issuance. A minimum detection limit (MDL) can be used to establish background as a groundwater protection standard. Any component required in a RCRA facility investigation (RFI), such as monitoring releases not requiring immediate response, should be included as a permit condition. Monitoring wells installed as part of a HSWA corrective action may be designated as point of compliance wells. Permits containing corrective action conditions for groundwater treatment programs must specify methods of handling groundwater containing hazardous waste and must include pumping and removal requirements. Air stripping may not be an appropriate treatment method for groundwater contaminated with methyl isobutyl ketone. A permit or 3008(h) order should address the air emissions from treatment units such as an air stripper. Includes criteria for the referral of facilities to the Agency for Toxic Substances aND DISEASE REGISTRY (ATSDR) UNDER 3019. Emerging technologies, such as in-situ bio-reclamation, should be demonstrated as effective in pilot-scale field studies prior to approval. 264 Subpart F compliance monitoring standards should be applied to the verification monitoring at solid waste management units (SWMUs) during corrective action. A HSWA corrective action pe
rmit may include a technical feasibility clause discontinuing the program once contaminant levels can no longer be reduced. EPA discourages the approval of a waiver allowing the disposal of nonhazardous waste in a landfill that has lost interim status.
 
03/02/1988CLEANUP LEVELS FOR LEAD AND CADMIUM IN SOILS FOR CLEAN CLOSUREMemo
 Description: VERIFIED REFERENCE DOSES (RFDS) AND Carcinogenic Potency Factors (CPFs) can be used to set soil cleanup levels during clean closures of surface impoundments, waste piles, and land treatment units. Where no EPA-recommended health-based limit exists for a contaminant, a soil cleanup level may be based on background levels or by data developed by the owner to support a health-based limit. If the cleanup level cannot be established, then clean closure cannot be achieved and the unit (i.e. surface impoundment, waste pile, or land treatment unit) must close as a landfill. Provides guidance for determining the background levels for lead in soil for clean closures of surface impoundments, waste piles, and land treatment units. Discusses how to determine background levels of lead in soil.
 
02/01/1988CLEAN CLOSURE OF INTERIM STATUS SURFACE IMPOUNDMENT AND WASTE PILEQuestion & Answer
 Description: Surface impoundments, waste piles, landfills, and land treatment units which received waste after 7/26/82 or certified closure after 1/26/83 must either have post-closure permits or demonstrate that clean closure was equivalent to Part 264 closure (270.1(c)) (SEE ALSO: 63 FR 56711; 10/22/98). Post-closure permits for these units would include Part 264 groundwater monitoring, unsaturated zone monitoring, corrective action and post-closure care.
 
01/02/1988DRAINAGE WATER BENEATH LAND TREATMENT UNITS AT OIL REFINERIESMemo
 Description: Groundwater containing hazardous leachate from a land treatment unit is hazardous. Liners, ditches, and pipes are extensions of the land treatment unit for a no migration petition. A Part B demonstration does not replace a no migration petition. A RCRA facility investigation (RFI) does not replace an evaluation of air emissions in a no migration petition.
 
12/17/1987CLOSURE AND POST-CLOSURE ISSUES FOR INTERIM STATUS SURFACE IMPOUNDMENTSMemo
 Description: EPA may extend the time allowed for the closure of a surface impoundment to allow groundwater corrective action so that the owner can achieve clean closure. Units closing by removal under Part 265 (e.g. surface impoundments, waste piles, and land treatment units) must obtain post-closure permits unless the owner demonstrates equivalence with 264.228, 264.280(e), or 264.258 closure by decontamination standards (SEE ALSO: 63 FR 56711; 10/22/98). The owner of an interim status landfill that has closed by removal and has not triggered groundwater assessment does not have to monitor groundwater for the full list of Appendix VIII or IX constituents. Groundwater evaluation conducted as part of the 265 clean-closure demonstration should establish constituents that could reasonably be expected to exist at the impoundment. A surface impoundment that has triggered groundwater assessment may not be able to clean close.
 
11/25/1987TREATMENT SURFACE IMPOUNDMENTS, REGULATORY OPTIONS AVAILABLE TO WOOD PRESERVERSMemo
 Description: A wood preserving treatment surface impoundment is not a hazardous waste experiment unit. A wood preservative surface impoundment must obtain a permit, close, or convert to a land treatment unit.
 
07/01/1987LAND TREATMENTQuestion & Answer
 Description: A land treatment unit must always have at least three feet between the bottom of the treatment zone and the seasonal high water table. If the bottom of the treatment zone extends less than five feet into the soil, the owner may measure three feet down from the actual bottom of the treatment zone.
 
06/26/1987GENERATOR REQUEST FOR EXEMPTION FROM OR EXTENSION OF LAND DISPOSAL RESTRICTIONSMemo
 Description: Land disposal includes land treatment. Restricted waste may not be land treated unless it meets the treatment standard or has been granted a no-migration variance.
 
03/30/1987SUMMARY OF PERMIT ASSISTANCE TEAM (PAT) COMMENTSMemo
 Description: A native soil foundation does not constitute a liner for the purposes of the 3005(j)(2) waiver. A 264.282 compatibility demonstration applies to both hazardous and nonhazardous waste. Addresses HSWA waste minimization requirements (3002(b)) and the application of sludge to land treatment units. The identification of principal hazardous constituents for land treated wastes must include all constituents that may enter the waste stream. A land treatment unit performance evaluation must include the unit’s ability to treat and degrade organic constituents, as well as its ability to immobilize heavy metals. Provides guidance on the frequency of soil pore liquid sampling at land treatment units (unsaturated zone monitoring) and guidance on screening groundwater monitoring wells. QA/QC methodology at a land treatment unit should include verification of the organic constituent analysis by gas chromatography/mass spectroscopy (GC/MS). Includes guidance on the content of construction quality assurance plans. A person who conducts quality assurance measures for surface impoundments, waste piles, and landfills should be independent of the construction contractor. Discusses the use of Method 9090 for compatibility testing of liner materials with waste or leachate. All man-made materials that contact waste or leachate should be subjected to the immersion test portion of 9090. A sample of waste or leachate used in compatibility testing must be representative of the actual waste or leachate managed in the surface impoundment, waste pile, or landfill. A concrete pad cannot be equivalent protection. If the design slope of a final landfill cover exceeds 3-5%, the applicant must demonstrate that soil erosion will not be excessive and may need to perform a slope stability analysis. Waste and soil settlement must be included in calculations for the final landfill cover design to be substituted for a waste pile liner as equivalent protection under 3015(a). A flexible membrane liner should not be used in a final cover when the landfill is unusually deep and slopes are steep. Clean, not contaminated, soil should be used for the final cover. A leachate collection system design should be based on realistic infiltration rates. Geogrid and geotextile materials used in place of conventional drainage materials for a landfill must have an equivalent drainage capacity of a one-foot layer of compacted sand. Berms constructed of manufactured slag should not contain hazardous constituents. For landfills, the use of a composite primary liner below the primary synthetic liner is allowable. An owner of a land treatment unit who cannot establish vegetative cover may use an alternate closure procedure. A facility cannot extend closure in order to receive nonhazardous waste (SUPERSEDED: see current 264.113(d)). Addresses the role of the Agency for Toxic Substances and Disease Registry (ATSDR) in exposure information and evaluation. The review of Exposure Information Reports should be coordinated with ongoing RCRA Facility Assessments.
 
07/15/1986LAND TREATMENT UNITS, DEPTH TO WATER TABLE REQUIREMENTMemo
 Description: The treatment zone in a land treatment unit must be one meter above the seasonally high water table.
 
06/12/1986BULK LIQUIDS AND DRAIN/LEACHING FIELDSMemo
 Description: Section 3004(c)(1) applies only to bulk liquid hazardous waste. the land disposal restrictions (LDR) limit the number of organic wastes placed on the land. Surface drain fields are regulated under RCRA as a land treatment facility, subsurface drain fields are regulated under SDWA.
 
01/31/1986RCRA CORRECTIVE ACTION PROCEDURES AND AUTHORITIESMemo
 Description: Discusses the procedures for terminating interim status. The applicability of corrective action to land disposal units receiving hazardous wastes after 7/26/82. The applicability of and authorities for corrective action and monitoring requirements for facilities undergoing closure with continuous releases. Guidance on fuels as a hazardous wastes (SEE ALSO: 59 FR 55778; 11/8/94).
 
07/17/1985SURFACE IMPOUNDMENTS/LAND TREATMENT UNITS REGULATION IF ASSOCIATED WWT SLUDGES ARE LISTEDMemo
 Description: Since any pollution abatement technique such as land treatment, disposal, or storage of a wastewater will invariably form a sludge, F-listed, K-listed, and characteristic sludges can be formed in situations where wastewaters are stored or disposed (i.e., not specifically treated). Discussion of the point of generation.
 
01/01/1985TREATMENT SURFACE IMPOUNDMENTS LOSING INTERIM STATUS BECAUSE OF NON-COMPLIANCE WITH GWM AND FINANCIAL RESPONSIBILITY REQUIREMENTSQuestion & Answer
 Description: Owners and operators of interim status land treatment units were required to submit a Part B application, certify compliance with groundwater monitoring, and obtain financial assurance by 11/8/85 (3005(e)(2)). Land disposal units include all land-based hazardous waste management systems.
 
10/01/1984WASTE DUMPED ON GROUND CONSIDERED STORAGE IN A WASTE PILEQuestion & Answer
 Description: If waste is dumped on the ground outside of a land treatment unit, the area should be regulated as a waste pile or landfill. EPA does not recommend dumping and spreading as an adequate land application procedure (SEE ALSO: 61 FR 18779; 4/29/96).
 
05/25/1984ANALYTICAL METHODS FOR PETROLEUM REFINING RESIDUES AND WASTESMemo
 Description: Guidance is provided on the analytical methods for petroleum refinery wastes that are the subject of a land treatment permit application (cover letter for “Handbook for the Analysis of Petroleum Refinery Residues and Waste”). A land treatment permit application should include total metal concentrations, not extraction procedure (EP) results.
 
05/01/1984CHECK LISTS FOR PERMIT APPLICATIONSQuestion & Answer
 Description: The check list in the “Permit Applicants Guidance Manual for Hazardous Waste Land Treatment, Storage, and Disposal Facilities” should be included in a Part B permit application, although there are no formal application format requirements.
 
04/03/1984LAND TREATMENT PERMIT APPLICATIONS - REFINERY WASTE ANALYSES GUIDANCEMemo
 Description: Appendix VIII constituents are to be used for petroleum waste delistings and land treatment unit permit applications. Discussion of the original "Skinner List" (SUPERSEDED: see RPC# 11/1/94-02).
 
04/15/1983Hazardous Waste Land TreatmentPublication
 Description: This document provides state-of-the-art information on all aspects of hazardous waste land treatment (HWLT), including design and design review, site selection, waste characterization, facility design, operation, and closure. It also examines the fate of both inorganic and organic compounds in a soil environment and provides a basis for development of treatment demonstrations.
 
12/29/1982LAND DISPOSAL PERMIT STRATEGYMemo
 Description: Discusses the historical priorities for permitting of land disposal units (surface impoundments, waste piles, land treatment units, and landfills).
 
02/01/1982GROUNDWATER MONITORING AND LEAKING WASTE PILESQuestion & Answer
 Description: An interim status waste pile leaking hazardous leachate into the ground is out of compliance. The owner or operator can take remedial action or modify their Part A permit application, reclassifying the waste pile as a land treatment unit or landfill, for which groundwater monitoring would be required under changes during interim status.
