Under subtitle C of the Small Business Liability Relief and Brownfields Revitalization Act, states and tribes can receive cooperative agreements to establish and enhance their response programs through the four elements and meet the public record requirements under the statute. Cooperative agreement recipients (‘‘recipients’’) have general reporting and record keeping requirements as a condition of their cooperative agreement that result in burden. A portion of this reporting and record keeping burden is authorized under 2 CFR part 1500 and identified in the EPA’s general grants ICR (OMB Control Number 2030–0020). EPA requires Brownfields program recipients to maintain and report additional information to EPA on the uses and accomplishments associated with funded brownfields activities. EPA uses several forms to assist recipients in reporting the information and to ensure consistency of the information collected. EPA uses this information to meet Federal stewardship responsibilities to manage and track how program funds are being spent, to evaluate the performance of the Brownfields Cleanup and Land Revitalization Program, to meet the Agency’s reporting requirements under the Government Performance Results Act, and to report to Congress and other program stakeholders on the status and accomplishments of the program. Respondents/affected entities: State/ local/tribal governments; Non-Profits. Respondent’s obligation to respond: Required to obtain or Retain Benefits (2 CFR part 1500). Estimated number of respondents: 2969 (total). Frequency of response: Bi-annual for subtitle C recipients; quarterly for subtitle A recipients.Total estimated burden: 6,144 hours (per year). Burden is defined at 5 CFR 1320.03(b). Total estimated cost: $712,108 (per year), includes $0 annualized capital or operation & maintenance costs. Changes in the Estimates: The overall burden has increased slightly by 379 hours since the last ICR submittal. This is the result of an increased response total of 123 additional responses.

A. Purpose of This Notice The Land Disposal Restrictions (LDRs) are a key part of the hazardous waste regulatory program under the Resource Conservation and Recovery Act (RCRA) and require that hazardous wastes meet certain treatment standards prior to land disposal. If these standards are not met, land disposal of the waste is prohibited. The RCRA statute and implementing regulations allow land disposal of hazardous waste not meeting applicable treatment standards where a No Migration Variance (NMV) is approved by EPA. An NMV is a formal decision that can be rendered by EPA in response to a petition filed with the Agency, to allow the land disposal at a particular facility of specific prohibited waste, i.e., a waste not meeting the applicable LDR treatment standards. In Section III of this notice, EPA is providing information for persons who may wish to apply for an NMV for one or more temporary waste piles, where treated hazardous waste that is expected to meet LDR standards is temporarily stored within the boundary of a hazardous waste landfill prior to moving that waste within the landfill to its final disposal or removing it for further treatment. khammond on DSKJM1Z7X2PROD with NOTICES C.

VerDate Sep<11>2014 19:19 Jan 17, 2021 Jkt 253001 B. Background The regulatory requirements for an NMV under the RCRA LDRs were first established in 1986,1 and in 1992, EPA issued guidance on these requirements.2 The 1992 guidance is applicable to landfills, surface impoundments, and waste piles, and also acknowledges temporary placement of waste under an approved NMV; however, the guidance did not address the specific situation identified in this notice where temporary piles of treated waste are placed within the boundary of a RCRApermitted hazardous waste landfill. Some commercial hazardous waste landfill facilities offer services for treating hazardous waste in addition to providing landfill disposal. In determining the appropriate treatment, facilities evaluate the incoming waste streams to identify the best treatment strategy (e.g., type and quantity of reagents, mixing times). Facilities rely on information in waste profiles provided by generators, waste characterization conducted by the facility (including characterization specified in their Waste Analyses Plan 1 51 FR 40572, November 7, 1986. Migration Variances to the Hazardous Waste Land Disposal Prohibitions: A Guidance Manual for Petitioners, EPA Office of Solid Waste, July 1992, EPA–530–R92–023. 5191 or WAP), as well as familiarity with waste streams (e.g., if a waste stream is received on a routine basis from the same source). Once treated, facilities may store the treated (e.g., stabilized) waste temporarily in units such as tanks, containers or containment buildings to allow the treated waste to ‘‘cure’’ and/or to confirm that the treated waste meets the applicable LDR standards. The treated waste is then moved into the landfill for disposal. EPA is aware that some facilities have established procedures whereby a pile of treated hazardous waste is temporarily staged within the boundaries of the permitted subtitle C landfill while awaiting confirmation by the facility through testing results that the treatment program is performing as expected and that the treated waste meets the applicable LDR standards. Where the treated waste is confirmed to meet the LDR standards, the pile is moved to the ‘‘working face’’ of the landfill for final disposal. If there is an exceedance of an LDR standard, the pile is picked up and returned to the treatment process for further treatment. Any instance where a pile does not meet the applicable LDR standards and has not been granted an NMV would be a violation of the LDR requirements—the hazardous waste must either meet the LDR standards, or an approved NMV must be in place.3 C. The NMV Process The NMV petition submittal and decision process is found in 40 CFR 268.6. Review and approval of an NMV petition is delegated to the EPA Regional Administrator for the EPA Region in which the waste management unit is located. EPA does not authorize states to implement the NMV authority. As part of the petition process, EPA may request additional information from the petitioner to evaluate the demonstration. EPA will provide notice in the Federal Register of the intent to approve or deny the NMV petition with an opportunity for public comment. The final decision is to be published in the Federal Register, and petitions to renew must undergo notice and comment procedures as well. An NMV that has been issued can be revoked for cause, including if migration occurs. Once approved, the term of an NMV shall be no longer than the term of the RCRA subtitle C permit for a permitted disposal unit, and no longer than 10 years for a unit operating under interim status. The 1992 guidance should be 2 No PO 00000 Frm 00062 Fmt 4703 Sfmt 4703 3 Memorandum from Barnes Johnson to EPA Regional Division Directors, April 11, 2014; https:// rcrapublic.epa.gov/files/14843.pdf. E:\FR\FM\19JAN1.SGM 19JAN1 5192 Federal Register / Vol. 86, No. 11 / Tuesday, January 19, 2021 / Notices A. Demonstration Addressed by This Guidance This guidance addresses how to make a demonstration that the treated waste and constituents will not migrate beyond the temporary waste pile. The RCRA statutory language requires a demonstration ‘‘to a reasonable degree of certainty, that there will be no migration of hazardous constituents from the disposal unit or injection zone for as long as the waste remains hazardous’’ (RCRA § 3004(d)(1)). EPA has interpreted this language to mean that it must be demonstrated, to a reasonable degree of certainty, that hazardous constituents will not exceed Agency-approved health-based levels (or environmentally protective levels, if they are appropriate) beyond the boundary of the disposal unit. While it is EPA’s interpretation that man-made barriers or engineered systems (e.g., liner systems) alone generally will not meet the ‘‘no migration’’ standard, this is not the case for temporary land-based storage of treated waste as is being considered in this document. The containment of hazardous waste within engineered barriers can be considered in making the ‘‘no migration’’ demonstration for waste awaiting the results of verification sampling after treatment, provided that wastes are to be removed after a reasonably short storage period that may be conservatively projected to be well before the failure of the engineered barrier system.4 B. Information To Be Submitted to EPA EPA expects that petitioners will be able to take advantage of existing facility information (e.g., existing monitoring, inspections, engineered barriers, waste analyses), where appropriate, as part of any demonstration. In developing an NMV petition, a petitioner must satisfy the no migration criteria set forth in 40 CFR 268.6, and petitioners should describe any and all controls that will be applied to the temporary waste pile to prevent the migration of hazardous constituents from the pile, and, the monitoring that will be used to detect migration at the earliest practicable time. For example, the use of temporary barriers, such as plastic covers above and below the piles; visual monitoring and prompt responses to possible releases; and generally good housekeeping practices that ensure the treated waste remains in the pile during the temporary storage period would be elements to consider. Attributes of the permitted landfill cell (e.g., design, existing controls, monitoring) in which the pile or piles are located should also be taken into account to the extent that they support the demonstration criteria being applied to the piles themselves. In other words, if a particular control or requirement is in place for the landfill cell, and can prevent potential releases from the pile or piles, it should be described in the petition (and petitioners should specify how that control or requirement prevents migration from the boundary of the temporary waste pile). The regulations in 40 CFR 268.6(a) describe the components of what a demonstration must address; § 268.6(b) specifies certain criteria that must be satisfied for that demonstration, and § 268.6(c) describes the monitoring program that will be used to verify that the conditions of the NMV are being met. The components for an NMV demonstration outlined in § 268.6(a) are: • Descriptions of the specific waste(s) and specific unit for which the demonstration will be made; • Waste analysis describing the chemical and physical characteristics of the waste; • Comprehensive characterization of the disposal unit site, including air, soil, and water quality; • Monitoring plan to detect migration at the earliest practicable time; • Sufficient information to assure EPA that the owner/operator of the unit receiving the wastes will comply with other applicable federal, state, and local laws. 4 No Migration Variances to the Hazardous Waste Land Disposal Prohibitions: A Guidance Manual for Petitioners, EPA Office of Solid Waste, July 1992, EPA–530–R92–023. considered a resource for preparation of any submittal, in addition to the considerations described here for which EPA is requesting comment. khammond on DSKJM1Z7X2PROD with NOTICES III. NMV for Temporary Waste Piles Within a Subtitle C Landfill EPA is requesting comment on the information provided below. The contents of the guidance document do not have the force and effect of law and the Agency does not bind the public in any way and intends only to provide clarity to the public regarding existing requirements under the law or Agency policies, except as authorized by law or as incorporated into a contract. This information is not a substitute for compliance with 40 CFR 268.6, but provides additional information in the specific situation where hazardous waste is treated and then is temporarily stored in piles within a permitted subtitle C landfill, prior to either transfer to the working face of the landfill, or removal for retreatment if necessary. VerDate Sep<11>2014 19:19 Jan 17, 2021 Jkt 253001 PO 00000 Frm 00063 Fmt 4703 Sfmt 4703 Below are some considerations regarding these components with respect to NMV petition submittals for piles temporarily storing waste within a subtitle C landfill that has been treated with the expectation that it meets the applicable LDR standards for permanent disposal in the landfill. Facility Description—The NMV petition should include a description of the hazardous waste management facility where the waste will be treated, temporarily stored, and permanently disposed in sufficient detail to familiarize the reviewer with its overall operation. This type of information and level of detail will be similar to those included in the facility’s RCRA permit application. The facility name, mailing address, and physical location should be provided, together with information on a point of contact for correspondence concerning the petition. Detailed design, layout, and operating plans should be provided for the unit covered by the petition. Unit descriptions should focus on waste isolation capabilities of the unit. Unit(s) Covered by the NMV—While the temporary waste piles addressed in this document are located within the boundaries of the RCRA-permitted landfill cell, the unit to which the variance applies, as envisioned in this guidance, is the pile itself. The information presented here is for a demonstration that the treated waste and constituents will not migrate beyond the temporary waste pile. Where different piles containing different types of treated hazardous waste are simultaneously staged within the landfill cell, each pile should be described and will be evaluated, as necessary, individually by EPA in order to properly assess potential releases when evaluating petitions, and for evaluating the monitoring that will be part of implementing any approved variance. Where multiple piles contain the same or similar wastes, the petition can address these units as a group. For example, where two or more piles are similar in terms of the nature and concentration of constituents, treatment used, waste matrices, etc., the petition need not separately specify or discuss such information for each individual pile where such piles are effectively being managed as a single unit. Similarly, where the design, inspection, and monitoring of the pile coverings and liners that will be used to prevent releases from the piles are the same for multiple piles, such information on each individual pile need not be specified. In other words, a successful petition could include several categories of treated waste piles, but sufficient E:\FR\FM\19JAN1.SGM 19JAN1 khammond on DSKJM1Z7X2PROD with NOTICES Federal Register / Vol. 86, No. 11 / Tuesday, January 19, 2021 / Notices information must be included so that the potential for releases, and proposed inspection and monitoring, can be evaluated by EPA. While the unit(s) to be evaluated under this guidance are the temporary waste piles, petitioners should also submit information related to the landfill to the extent the information aids in any demonstration that hazardous constituents will not migrate beyond the boundary of the temporary waste pile. For example, hazardous waste landfill design and operating requirements (40 CFR 264.301) include run-on and run-off controls that may be important in any demonstration that hazardous waste will not migrate from the pile. The specific location of where the temporary waste piles will be placed within the landfill cell should be identified in the petition, together with any pertinent information as to why this location was selected and how it will prevent the migration of hazardous constituents from the pile. These locations will be identified as part of any approved variance. This document only applies where wastes managed in the temporary waste piles have been treated with the expectation that the waste meets the applicable LDR standards for permanent disposal in the landfill. A facility should include information about what types and quantities of waste are to be managed in the temporary waste piles and what treatment standards apply. Most of this information is presumed to already be available as part of the facility’s WAP and associated program for sampling and monitoring for compliance with the LDRs. Duration of Temporary Storage—The NMV is necessary to ensure that any temporary storage of treated hazardous waste complies with the stringent statutory and regulatory standards in those instances where the hazardous waste that was treated and placed in a temporary waste pile does not meet LDRs. The approach described in this document is conditioned upon the temporary nature of the storage of treated hazardous waste within the landfill, and is intended for situations where the temporary waste piles are used as part of an overall strategy to confirm consistent and compliant treatment that meets the applicable LDR treatment standards. The petition should include a description of the length of time the waste is managed in the pile before either transfer to the working face of the landfill, or removal for retreatment, if necessary. A range of time may be provided, but EPA emphasizes that the temporary nature of the pile must be VerDate Sep<11>2014 19:19 Jan 17, 2021 Jkt 253001 clearly characterized in the petition, such as through maximum storage times or other procedures described in the application, that may become part of the conditions established in an approved variance. However, if any particular staging location routinely receives treated waste that does not meet applicable LDR standards, then the ‘‘temporary’’ aspect of storage for a given location may be called into question, which could affect the ability for EPA to grant the NMV. This also raises the separate question of whether the overall treatment process is operating as well as it should. Therefore, it is important for the petition to describe in sufficient detail the procedures used to treat, test, and confirm that wastes meet LDR standards, and how this information will be used to determine when a pile will be removed either for retreatment, or for final disposal. Such information should be available as part of the facility’s WAP and may include: • Number and type (e.g., random grab) of samples taken after treatment for LDR compliance; • Methodology used to select number and type of samples; • Level of confidence that all waste is treated to LDR treatment standards (level of confidence related to number of samples achieving LDRs); • List of regulated constituents (suite of metals, selected organics, cyanide). Monitoring Plan—40 CFR 268.6(a)(4) requires a petition to include a monitoring plan to verify continued compliance with the conditions of the no migration variance. Pursuant to 40 CFR 268.6(a)(4), the monitoring plan must be designed to detect migration ‘‘at the earliest practicable time.’’ 40 CFR 268.6(c) lays out the specific information required in the monitoring plan. In addition to these requirements, the monitoring plan should also describe the sampling and analysis of the treated waste that determines when the temporary waste pile will be moved to the working face of the landfill for final disposal. The demonstration should allow EPA to understand the process and timing of LDR treatment and confirmation that LDRs are met; this is fundamental to defining the scope and duration of storing treated waste temporarily.

II. General Information

A. Purpose of This Notice

    The Land Disposal Restrictions (LDRs) are a key part of the 
hazardous waste regulatory program under the Resource Conservation and 
Recovery Act (RCRA) and require that hazardous wastes meet certain 
treatment standards prior to land disposal. If these standards are not 
met, land disposal of the waste is prohibited. The RCRA statute and 
implementing regulations allow land disposal of hazardous waste not 
meeting applicable treatment standards where a No Migration Variance 
(NMV) is approved by EPA. An NMV is a formal decision that can be 
rendered by EPA in response to a petition filed with the Agency, to 
allow the land disposal at a particular facility of specific prohibited 
waste, i.e., a waste not meeting the applicable LDR treatment 
standards. In Section III of this notice, EPA is providing information 
for persons who may wish to apply for an NMV for one or more temporary 
waste piles, where treated hazardous waste that is expected to meet LDR 
standards is temporarily stored within the boundary of a hazardous 
waste landfill prior to moving that waste within the landfill to its 
final disposal or removing it for further treatment.

B. Background

    The regulatory requirements for an NMV under the RCRA LDRs were 
first established in 1986,\1\ and in 1992, EPA issued guidance on these 
requirements.\2\ The 1992 guidance is applicable to landfills, surface 
impoundments, and waste piles, and also acknowledges temporary 
placement of waste under an approved NMV; however, the guidance did not 
address the specific situation identified in this notice where 
temporary piles of treated waste are placed within the boundary of a 
RCRA-permitted hazardous waste landfill.

---------------------------------------------------------------------------

    Some commercial hazardous waste landfill facilities offer services 
for treating hazardous waste in addition to providing landfill 
disposal. In determining the appropriate treatment, facilities evaluate 
the incoming waste streams to identify the best treatment strategy 
(e.g., type and quantity of reagents, mixing times). Facilities rely on 
information in waste profiles provided by generators, waste 
characterization conducted by the facility (including characterization 
specified in their Waste Analyses Plan or WAP), as well as familiarity 
with waste streams (e.g., if a waste stream is received on a routine 
basis from the same source). Once treated, facilities may store the 
treated (e.g., stabilized) waste temporarily in units such as tanks, 
containers or containment buildings to allow the treated waste to 
``cure'' and/or to confirm that the treated waste meets the applicable 
LDR standards. The treated waste is then moved into the landfill for 
disposal.
    EPA is aware that some facilities have established procedures 
whereby a pile of treated hazardous waste is temporarily staged within 
the boundaries of the permitted subtitle C landfill while awaiting 
confirmation by the facility through testing results that the treatment 
program is performing as expected and that the treated waste meets the 
applicable LDR standards. Where the treated waste is confirmed to meet 
the LDR standards, the pile is moved to the ``working face'' of the 
landfill for final disposal. If there is an exceedance of an LDR 
standard, the pile is picked up and returned to the treatment process 
for further treatment. Any instance where a pile does not meet the 
applicable LDR standards and has not been granted an NMV would be a 
violation of the LDR requirements--the hazardous waste must either meet 
the LDR standards, or an approved NMV must be in place.\3\

C. The NMV Process

    The NMV petition submittal and decision process is found in 40 CFR 
268.6. Review and approval of an NMV petition is delegated to the EPA 
Regional Administrator for the EPA Region in which the waste management 
unit is located. EPA does not authorize states to implement the NMV 
authority. As part of the petition process, EPA may request additional 
information from the petitioner to evaluate the demonstration. EPA will 
provide notice in the Federal Register of the intent to approve or deny 
the NMV petition with an opportunity for public comment. The final 
decision is to be published in the Federal Register, and petitions to 
renew must undergo notice and comment procedures as well. An NMV that 
has been issued can be revoked for cause, including if migration 
occurs. Once approved, the term of an NMV shall be no longer than the 
term of the RCRA subtitle C permit for a permitted disposal unit, and 
no longer than 10 years for a unit operating under interim status. The 
1992 guidance should be

[[Page 5192]]

considered a resource for preparation of any submittal, in addition to 
the considerations described here for which EPA is requesting comment.

III. NMV for Temporary Waste Piles Within a Subtitle C Landfill

    EPA is requesting comment on the information provided below. The 
contents of the guidance document do not have the force and effect of 
law and the Agency does not bind the public in any way and intends only 
to provide clarity to the public regarding existing requirements under 
the law or Agency policies, except as authorized by law or as 
incorporated into a contract. This information is not a substitute for 
compliance with 40 CFR 268.6, but provides additional information in 
the specific situation where hazardous waste is treated and then is 
temporarily stored in piles within a permitted subtitle C landfill, 
prior to either transfer to the working face of the landfill, or 
removal for retreatment if necessary.

A. Demonstration Addressed by This Guidance

    This guidance addresses how to make a demonstration that the 
treated waste and constituents will not migrate beyond the temporary 
waste pile. The RCRA statutory language requires a demonstration ``to a 
reasonable degree of certainty, that there will be no migration of 
hazardous constituents from the disposal unit or injection zone for as 
long as the waste remains hazardous'' (RCRA Sec.  3004(d)(1)). EPA has 
interpreted this language to mean that it must be demonstrated, to a 
reasonable degree of certainty, that hazardous constituents will not 
exceed Agency-approved health-based levels (or environmentally 
protective levels, if they are appropriate) beyond the boundary of the 
disposal unit. While it is EPA's interpretation that man-made barriers 
or engineered systems (e.g., liner systems) alone generally will not 
meet the ``no migration'' standard, this is not the case for temporary 
land-based storage of treated waste as is being considered in this 
document. The containment of hazardous waste within engineered barriers 
can be considered in making the ``no migration'' demonstration for 
waste awaiting the results of verification sampling after treatment, 
provided that wastes are to be removed after a reasonably short storage 
period that may be conservatively projected to be well before the 
failure of the engineered barrier system.\4\

B. Information To Be Submitted to EPA

    EPA expects that petitioners will be able to take advantage of 
existing facility information (e.g., existing monitoring, inspections, 
engineered barriers, waste analyses), where appropriate, as part of any 
demonstration. In developing an NMV petition, a petitioner must satisfy 
the no migration criteria set forth in 40 CFR 268.6, and petitioners 
should describe any and all controls that will be applied to the 
temporary waste pile to prevent the migration of hazardous constituents 
from the pile, and, the monitoring that will be used to detect 
migration at the earliest practicable time. For example, the use of 
temporary barriers, such as plastic covers above and below the piles; 
visual monitoring and prompt responses to possible releases; and 
generally good housekeeping practices that ensure the treated waste 
remains in the pile during the temporary storage period would be 
elements to consider. Attributes of the permitted landfill cell (e.g., 
design, existing controls, monitoring) in which the pile or piles are 
located should also be taken into account to the extent that they 
support the demonstration criteria being applied to the piles 
themselves. In other words, if a particular control or requirement is 
in place for the landfill cell, and can prevent potential releases from 
the pile or piles, it should be described in the petition (and 
petitioners should specify how that control or requirement prevents 
migration from the boundary of the temporary waste pile).
    The regulations in 40 CFR 268.6(a) describe the components of what 
a demonstration must address; Sec.  268.6(b) specifies certain criteria 
that must be satisfied for that demonstration, and Sec.  268.6(c) 
describes the monitoring program that will be used to verify that the 
conditions of the NMV are being met. The components for an NMV 
demonstration outlined in Sec.  268.6(a) are:
     Descriptions of the specific waste(s) and specific unit 
for which the demonstration will be made;
     Waste analysis describing the chemical and physical 
characteristics of the waste;
     Comprehensive characterization of the disposal unit site, 
including air, soil, and water quality;
     Monitoring plan to detect migration at the earliest 
practicable time;
     Sufficient information to assure EPA that the owner/
operator of the unit receiving the wastes will comply with other 
applicable federal, state, and local laws.
    Below are some considerations regarding these components with 
respect to NMV petition submittals for piles temporarily storing waste 
within a subtitle C landfill that has been treated with the expectation 
that it meets the applicable LDR standards for permanent disposal in 
the landfill.
    Facility Description--The NMV petition should include a description 
of the hazardous waste management facility where the waste will be 
treated, temporarily stored, and permanently disposed in sufficient 
detail to familiarize the reviewer with its overall operation. This 
type of information and level of detail will be similar to those 
included in the facility's RCRA permit application. The facility name, 
mailing address, and physical location should be provided, together 
with information on a point of contact for correspondence concerning 
the petition. Detailed design, layout, and operating plans should be 
provided for the unit covered by the petition. Unit descriptions should 
focus on waste isolation capabilities of the unit.
    Unit(s) Covered by the NMV--While the temporary waste piles 
addressed in this document are located within the boundaries of the 
RCRA-permitted landfill cell, the unit to which the variance applies, 
as envisioned in this guidance, is the pile itself. The information 
presented here is for a demonstration that the treated waste and 
constituents will not migrate beyond the temporary waste pile. Where 
different piles containing different types of treated hazardous waste 
are simultaneously staged within the landfill cell, each pile should be 
described and will be evaluated, as necessary, individually by EPA in 
order to properly assess potential releases when evaluating petitions, 
and for evaluating the monitoring that will be part of implementing any 
approved variance. Where multiple piles contain the same or similar 
wastes, the petition can address these units as a group. For example, 
where two or more piles are similar in terms of the nature and 
concentration of constituents, treatment used, waste matrices, etc., 
the petition need not separately specify or discuss such information 
for each individual pile where such piles are effectively being managed 
as a single unit. Similarly, where the design, inspection, and 
monitoring of the pile coverings and liners that will be used to 
prevent releases from the piles are the same for multiple piles, such 
information on each individual pile need not be specified. In other 
words, a successful petition could include several categories of 
treated waste piles, but sufficient

[[Page 5193]]

information must be included so that the potential for releases, and 
proposed inspection and monitoring, can be evaluated by EPA.
    While the unit(s) to be evaluated under this guidance are the 
temporary waste piles, petitioners should also submit information 
related to the landfill to the extent the information aids in any 
demonstration that hazardous constituents will not migrate beyond the 
boundary of the temporary waste pile. For example, hazardous waste 
landfill design and operating requirements (40 CFR 264.301) include 
run-on and run-off controls that may be important in any demonstration 
that hazardous waste will not migrate from the pile. The specific 
location of where the temporary waste piles will be placed within the 
landfill cell should be identified in the petition, together with any 
pertinent information as to why this location was selected and how it 
will prevent the migration of hazardous constituents from the pile. 
These locations will be identified as part of any approved variance.
    This document only applies where wastes managed in the temporary 
waste piles have been treated with the expectation that the waste meets 
the applicable LDR standards for permanent disposal in the landfill. A 
facility should include information about what types and quantities of 
waste are to be managed in the temporary waste piles and what treatment 
standards apply. Most of this information is presumed to already be 
available as part of the facility's WAP and associated program for 
sampling and monitoring for compliance with the LDRs.
    Duration of Temporary Storage--The NMV is necessary to ensure that 
any temporary storage of treated hazardous waste complies with the 
stringent statutory and regulatory standards in those instances where 
the hazardous waste that was treated and placed in a temporary waste 
pile does not meet LDRs. The approach described in this document is 
conditioned upon the temporary nature of the storage of treated 
hazardous waste within the landfill, and is intended for situations 
where the temporary waste piles are used as part of an overall strategy 
to confirm consistent and compliant treatment that meets the applicable 
LDR treatment standards.
    The petition should include a description of the length of time the 
waste is managed in the pile before either transfer to the working face 
of the landfill, or removal for retreatment, if necessary. A range of 
time may be provided, but EPA emphasizes that the temporary nature of 
the pile must be clearly characterized in the petition, such as through 
maximum storage times or other procedures described in the application, 
that may become part of the conditions established in an approved 
variance.
    However, if any particular staging location routinely receives 
treated waste that does not meet applicable LDR standards, then the 
``temporary'' aspect of storage for a given location may be called into 
question, which could affect the ability for EPA to grant the NMV. This 
also raises the separate question of whether the overall treatment 
process is operating as well as it should. Therefore, it is important 
for the petition to describe in sufficient detail the procedures used 
to treat, test, and confirm that wastes meet LDR standards, and how 
this information will be used to determine when a pile will be removed 
either for retreatment, or for final disposal. Such information should 
be available as part of the facility's WAP and may include:
     Number and type (e.g., random grab) of samples taken after 
treatment for LDR compliance;
     Methodology used to select number and type of samples;
     Level of confidence that all waste is treated to LDR 
treatment standards (level of confidence related to number of samples 
achieving LDRs);
     List of regulated constituents (suite of metals, selected 
organics, cyanide).
    Monitoring Plan--40 CFR 268.6(a)(4) requires a petition to include 
a monitoring plan to verify continued compliance with the conditions of 
the no migration variance. Pursuant to 40 CFR 268.6(a)(4), the 
monitoring plan must be designed to detect migration ``at the earliest 
practicable time.'' 40 CFR 268.6(c) lays out the specific information 
required in the monitoring plan. In addition to these requirements, the 
monitoring plan should also describe the sampling and analysis of the 
treated waste that determines when the temporary waste pile will be 
moved to the working face of the landfill for final disposal. The 
demonstration should allow EPA to understand the process and timing of 
LDR treatment and confirmation that LDRs are met; this is fundamental 
to defining the scope and duration of storing treated waste 
temporarily.
