TITLE 329 SOLID WASTE MANAGEMENT DIVISION

SECOND NOTICE OF COMMENT PERIOD
LSA Document #21-458

COAL COMBUSTION RESIDUALS


PURPOSE OF NOTICE
The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at 329 IAC 10-3-1, 329 IAC 10-3-4, and 329 IAC 10-9-1, and the addition of a new article at 329 IAC 14, concerning the establishment of a state permitting program for coal combustion residuals (CCR). IDEM seeks comment on the affected citations listed and any other provisions of Title 329 that may be affected by this rulemaking.

HISTORY
First Notice of Comment Period: October 13, 2021, Indiana Register (DIN: 20211013-IR-329210458FNA).



SUBJECT MATTER AND BASIC PURPOSE OF RULEMAKING
Basic Purpose and Background
On April 17, 2015, the United States Environmental Protection Agency (U.S. EPA) published a final rule in the Federal Register (FR) at 80 FR 21302 that established national minimum criteria for the disposal of CCR as a solid waste, and the design, operation, and closure of new and existing CCR landfills and surface impoundments under Subtitle D of the Resource Conservation and Recovery Act of 1976. This final rule became effective on October 19, 2015, and is codified in the Code of Federal Regulations (CFR) at 40 CFR 257, Subpart D.
When the federal CCR rule was first established in 2015, Indiana rules at 329 IAC 10 permitted regulated entities to dispose of CCR in restricted waste sites. These requirements were created before promulgation of the federal standards at 40 CFR 257, Subpart D, and differed from the federal standards in some cases. Consequently, IDEM published a final rule in the Indiana Register on December 7, 2016, that incorporated by reference the federal standards for CCR surface impoundments at 40 CFR 257, Subpart D into 329 IAC 10-9-1.
After promulgation of the U.S. EPA final rule in 2015, the United States Congress passed the Water Infrastructure Improvement for the Nation Act of 2016 (WIIN Act). Section 2301 of the WIIN Act, codified at 42 U.S.C. 6945(d), provides the opportunity for states to seek U.S. EPA approval to operate a state permit program for CCR units that is at least as protective as the federal standards.
This rulemaking is mandated by portions of Indiana Public Law 100-2021, codified at IC 13-19-3-1 and IC 13-19-3-3. The goal of this rulemaking is to comply with those amended statutes and establishes a state permit program under Section 2301 of the WIIN Act, 42 U.S.C. 6945(d), for the implementation in Indiana of the federal CCR rule. This comprehensive state-operated permit program for CCR units replaces the current partial incorporation of the federal rule at 329 IAC 10-9-1 and is at least as protective as the federal standards at 40 CFR 257, Subpart D for both CCR surface impoundments and CCR landfills. To ensure successful implementation of the federal program, this rulemaking incorporates by reference sections from U.S. EPA's 2015 final rule and the subsequent amendments to that rule.
The federal requirements at 40 CFR 257, Subpart D for CCR surface impoundments and landfills are self-implementing, but there is currently no federal rule that establishes permitting regulations for CCR owners and operators, although it is U.S. EPA's intention to establish a CCR permitting rule in the future. The state-specific standards and amendments to the incorporated federal regulations included in the draft rule language closely align with IDEM's existing closure approval program and requirements for surface impoundments and landfills, and some of these standards include requirements beyond what is specified in the federal rule while others offer compliance alternatives and flexibility. These additional requirements are as follows:
• Length requirements for final covers and submittal of final cover design at 40 CFR 257.102(d)(3)(i)(A) and 40 CFR 257.102(d)(3)(i)(B).
• Replacement of deed notations at 40 CFR 257.102(i) and 40 CFR 257.105(i)(9) with environmental restrictive covenants.
• Addition of closure plan requirements from MSWLF state rules at 329 IAC 10-22-2(c)(2), 329 IAC 10-22-2(c)(5), 329 IAC 10-22-2(c)(8), 329 IAC 10-22-2(c)(10), and 329 IAC 10-22-2(c)(11), and in conjunction with CCR state rule requirements, and inclusion of items needed for cost estimates and financial assurance.
• Inclusion of 329 IAC 10-22-3 concerning partial closure certification for CCR units and overfills.
• Addition of 329 IAC 10-23-3(c)(4) for leachate collection requirements, cost estimates, and financial assurance.
• Inclusion of 329 IAC 10-30-4(b)(8) plan specifications for Type I or Type II restricted waste sites for the incremental closure standard for CCR landfills and overfills.
• Addition of 329 IAC 10-31-2(a)(1), 329 IAC 10-31-2(a)(2), 329 IAC 10-31-2(a)(4), 329 IAC 10-31-2(a)(5), 329 IAC 10-31-2(a)(6), and 329 IAC 10-31-2(a)(7) for post-closure duties, post-closure plan, and post-closure certification.
• Addition of 329 IAC 10-28-13 for fugitive dust controls from restricted waste sites.
• Addition of a requirement to 40 CFR 257.81 that states that CCR landfills must not deposit solid waste in standing or ponded water except for that water resulting from precipitation directly upon the working face.
• Addition of 40 CFR 257.83, 40 CFR 257.84, and 329 IAC 10-20-28 that describe the criteria of an inspection.
• Revision of 40 CFR 257.90(e) to semiannual monitoring reports, and when applicable, a corrective action report, and requirement to submit to IDEM within 60 days of sampling event.
• Addition of new provisions at 40 CFR 257.90(e) that state: "the owner, operator, or permittee shall prepare groundwater potentiometric-surface maps, or flow maps, of each aquifer being monitored at the site each time groundwater samples are collected from groundwater monitoring wells"; and "the owner, operator, or permittee shall submit a copy of the water levels, analytical results, and field measurements submitted in an electronic file format as prescribed by the commissioner.".
• Replacement of the introductory paragraph at 40 CFR 257.91(a)(1) with the following: "Accurately represent the quality of background groundwater that has not been affected by leakage from a CCR unit or facility activities that may contribute constituents listed in Appendices III and IV of this part against which background comparisons occur. A determination of background quality may include sampling of wells that are not hydraulically upgradient of the CCR management area where: (i) and (ii) remain unchanged.".
• Revision to 40 CFR 257.91(c)(1) to require a maximum 500-foot horizontal spacing for downgradient wells.
• Replacement of paragraph at 40 CFR 257.91(c)(2) with the following: "Additional monitoring wells as necessary to accurately represent the quality of background groundwater that has not been affected by leakage from a CCR unit or facility activities that may contribute constituents listed in Appendices III and IV of this part against which background comparisons occur, and the quality of groundwater passing the waste boundary of the CCR unit.".
• Revision to 40 CFR 257.91(e) to add the requirement that the design and installation of the monitoring wells must follow 329 IAC 10-21-4 and 312 IAC 13-8-3.
• Revision to 40 CFR 257.93(h)(2) to be within sixty days.
• Addition of the following language to 40 CFR 257.94(a)(1): "Appropriate monitoring constituents must be determined and added to the Appendix III list by the commissioner based on constituents of any nonCCR waste permitted to be accepted at the facility.".
• Addition of the following language to 40 CFR 257.95(b)(1): "Appropriate monitoring constituents must be determined and added to the Appendix IV list by the commissioner based on constituents of any nonCCR waste permitted to be accepted at the facility.".
• Addition of concluding sentence to 40 CFR 257.95(f): "Whenever results of total chromium occur at or above its maximum contaminant level, the permittee must speciate and report both trivalent and hexavalent chromium.".
• Addition of "Boron 4,000 μg/l" to 40 CFR 257.95(h)(2).
• Addition of the following language to 40 CFR 257.95(h)(4): "For constituents for which there are no levels specified in paragraphs (h)(1) and (h)(2) of this section, the background concentration.".
• Revision to 40 CFR 257.97(a) to specify the submission of semiannual report(s) and the final report to the commissioner.
• Revision to 40 CFR 257.105(h)(1) from "annual" to "semiannual".
• Addition of word "post" before "closure" in 40 CFR 257.105(i)(12).
• Addition of "Boron" to Appendix IV.
After adoption of this rulemaking, IDEM will submit the state permit program to U.S. EPA for approval, in accordance with the provisions of Section 2301 of the WIIN Act. IDEM seeks comment on the affected citations listed, including suggestions for specific language, any other provisions of Title 329 that may be affected by this rulemaking, and alternative ways to achieve the purpose of the rulemaking.

IC 13-14-9-4 Identification of Rule Elements that Impose Restrictions and Requirements More Stringent Than Federal Law or That Apply in a Subject Area in which Federal Law does not Impose a Restriction or Requirement
In addition to incorporating federal standards into Indiana rules, as mandated by IC 13-19-3-1 and IC 13-19-3-3, this rulemaking codifies restrictions and requirements already imposed under existing Indiana closure rules. These rules have been the basis for closure of CCR units, closures that began prior to the codification of the current federal regulations. One of the goals of this rulemaking is to integrate the existing state closure regulations with the federal requirements to ensure that all closure activities are protective of human health and the environment and align with the closure standards under the federal program.
The list above in the Basic Purpose and Background Section identifies draft rule elements that diverge from or make changes to the federal CCR rule at 40 CFR 257, Subpart D, to codify state-specific standards, some of which could be construed as more stringent than federal law.

Potential Fiscal Impact
Public Law 165-2021 appropriates $100,000 to the newly established CCR Program Fund for Fiscal Year (FY) 2021-2022, and $450,000 for FY 2022-2023. Additionally, a portion of Public Law 165-2021, codified at IC 13-19-3-3(i), establishes new fees for CCR surface impoundments as follows:
• An initial one (1) time permit fee of twenty thousand five hundred dollars ($20,500) for each CCR surface impoundment regulated under the state permit program.
• An annual fee of twenty thousand five hundred dollars ($20,500) for each CCR surface impoundment regulated under the state permit program that has not completed closure in accordance with Section 257.102 of the federal CCR rule. The duty to pay the fee established by this subdivision does not apply on an annual basis until three hundred sixty-five (365) days after the initial one (1) time permit fee established by subdivision (1) has been assessed.
• An annual fee of ten thousand dollars ($10,000) for each CCR surface impoundment regulated under the state permit program that has been closed and for which post-closure care has been initiated and is still required in accordance with Section 257.104 of the federal CCR rule. The duty to pay the fee established by this subdivision does not apply on an annual basis until three hundred sixty-five (365) days after the initial one (1) time permit fee established by subdivision (1) has been assessed.
Administrative costs will also be incurred by IDEM for the preparation of permit applications. In accordance with the portion of Public Law 100-2021 codified at IC 13-19-3-3(g), IDEM cannot collect any of the fees for CCR surface impoundments until the Environmental Rules Board has adopted a final rule for the establishment of the new state CCR permit program and U.S. EPA has approved the permit program pursuant to 42 U.S.C. 6945(d)(1).

SUMMARY/RESPONSE TO COMMENTS FROM THE FIRST COMMENT PERIOD
IDEM requested public comment from October 13, 2021, through November 12, 2021, on alternative ways to achieve the purpose of the rule and suggestions for the development of draft rule language. IDEM received comments from the following parties by the comment period deadline:
Mindy Westrick Brown, Indiana Energy Association (IEA)
Lisa Evans, Earthjustice (EJ)
Tim Maloney, Hoosier Environmental Council (HEC)
Kerwin Olson, Citizens Action Coalition (CAC)
Amanda Shepherd, Sierra Club Hoosier Chapter (SCHC)
Susan Thomas, Just Transition Northwest Indiana (JTNI)
Following is a summary of the comments received and IDEM's responses thereto:
Comment: The commenter supports this rulemaking conditioned on the requirement that a state CCR permit program does not include requirements more stringent than the federal CCR rule. (IEA)
Response: IDEM's CCR permit program must be at least as stringent as federal law in order to gain EPA approval and operate in lieu of federal law. There are some state-specific requirements, listed above, in the rulemaking that differ from federal law but are consistent with IDEM's permitting process for other, similar facilities.
Comment: The commenter requests that IDEM create a workgroup for industry to collaborate with IDEM on the next steps of the rulemaking. (IEA)
Response: IDEM will determine whether a workgroup will be necessary upon publication of the Second Notice of Comment Period and the comments received.
Comment: The commenter requests that IDEM consider expanding the rule or pursuing an additional rulemaking in the future to bring references of the federal CCR rule to the latest federal rule. (IEA)
Response: IDEM appreciates this suggestion and will consider a potential rulemaking in the future when a new federal rule is finalized.
Comment: Commenters request that, due to the lack of circulation of the First Notice, including to known interested stakeholders including the undersigned, the comment period should be extended for 60 days. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: IDEM did not extend the First Notice of Comment Period but will consider a continuation of the Second Notice of Comment Period if it is determined to be necessary after publication in the Indiana Register.
Comment: Commenters state that there was a lack of adequate notice to the public and interested stakeholders about the rulemaking prior to publication of the First Notice in the Indiana Register. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: IDEM appreciates this feedback and strives to ensure that adequate notice is given to stakeholders and the public prior to the publication of rulemakings that are considered of great interest to the community. The First Notice is the initial notice to the public announcing the start of a new rulemaking and the subject matter to be covered.
Comment: Commenters feel that the state must strengthen its regulation of CCR disposal practices given the well-documented environmental contamination and public health risks resulting from production and disposal of CCR. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The purpose of this rulemaking is to establish a new state permitting program for disposal of CCR at 329 IAC 14 that is similar to the existing permitting program for municipal solid waste landfills (MSWLFs), and that will be at least as stringent as the federal rule at 40 CFR 257, Subpart D.
Comment: Commenters state that the new CCR permitting program should not authorize or allow CCR disposal practices to continue that have created the environmental and public health risks that are currently present in multiple CCR disposal sites throughout the state. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: This rulemaking is designed to minimize or eliminate risk to the environment and public health posed by CCR. It closely aligns with the current state permitting program for MSWLFs and is at least as stringent as the federal rule at 40 CFR 257, Subpart D.
Comment: Commenters assert that the new CCR permitting program should not perpetuate the use of coal for production of electricity at the same time that the state's electric utilities are reducing or eliminating coal as a fuel source. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The use of coal for electricity production is outside the scope of this rulemaking.
Comment: Commenters believe that the goals of the new CCR permitting program should be:
• To eliminate any present or future contact between groundwater and surface water and CCR at existing or new CCR disposal units;
• To prevent CCR from being released to the atmosphere as fugitive dust; and
• To prevent spills or other releases of CCR to surface waters or the land. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The goal of this rulemaking and IDEM's other environmental regulations is to minimize or eliminate environmental hazards and address human health concerns, including the specific goals stated by the commenters.
Comment: Commenters state that compliance capability should not be considered and opportunity for weakening the requirements of 40 CFR 257, Subpart D, as adopted in 329 IAC 10-9-1. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The CCR permitting program established by this rulemaking is an incorporation of the federal requirements at 40 CFR 257, Subpart D, and closely follows the permitting program currently in place in state rules for MSWLFs. As such, this rulemaking is at least as stringent as the federal rule, and therefore does not weaken its requirements.
Comment: Commenters state that the new CCR permit program rule should presume that there is no need for the construction and permitting of new CCR surface impoundments, and accordingly prohibit construction of new impoundments. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: This rulemaking will allow new CCR units to be constructed in accordance with the federal rule at 40 CFR 257, Subpart D.
Comment: Commenters believe the rule should require that new CCR landfills meet the existing requirements in 40 CFR 257 Subpart D, and that no new CCR landfills are located in a floodplain. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: This rulemaking incorporates by reference the federal rule at 40 CFR 257, Subpart D, and will therefore require that new CCR landfills meet those requirements.
Comment: Commenters state that no CCR surface impoundment should be permitted to close in place:
• If the impoundment is leaking, as determined by groundwater sampling that has identified GWPS exceedances.
• If the impoundment is unlined as defined in 40 CFR 257, Subpart D.
• If the impoundment has CCR in contact with groundwater, or likely to be in contact with groundwater during periods of seasonally high water levels in the neighboring water body.
• If the impoundment is located in a wellhead protection zone, floodplain, or seismic zone. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The CCR permitting program at 329 IAC 14 established by this rulemaking will require that impoundments be closed according to the federal rule at 40 CFR 257, Subpart D.
Comment: Commenters state that the financial assurance requirements now required for solid waste disposal units under Indiana rules should apply to all CCR disposal units, whether operating or closed. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: Under the federal rule at 40 CFR 257, Subpart D, and the new CCR permitting program at 329 IAC 14 established by this rulemaking, all permitted CCR units will follow financial assurance requirements.
Comment: Commenters state that public participation procedures for CCR permits should follow the procedural requirements of IC 13-15 and 329 IAC 10-12 and 329 IAC 10-13, and:
• IDEM shall ensure that notices for all CCR permitting, regulatory, and rulemaking activities are posted on its "Coal Combustion Residuals" webpage in a timely fashion, notwithstanding any other notice posting requirements or procedures. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: IDEM complies with federal requirements that require states with approved permitting programs to have a robust public participation program in place, including modern methods of communication such as emails and websites.
Comment: Commenters state that the closure requirements of 40 CFR 257, Subpart D should apply to open dump sites where CCR was stored, disposed of, or used as fill at a power plant site. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: This rulemaking incorporates the federal rule at 40 CFR 257, Subpart D, which requires that all sites meet the applicability requirements for CCR units. This rule does not extend beyond these requirements.
Comment: Commenters state that all requests for extensions in achieving compliance with 40 CFR 257, Subpart D and Indiana's rules be a matter of public information and open to public comment. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: Documents submitted to IDEM can be found in IDEM's Virtual File Cabinet and are available for public review. While the public may always provide comments on a document, official public comment periods will comply with the federal rule at 40 CFR 257, Subpart D, and the state's new CCR permitting rule at 329 IAC 14.
Comment: Commenters state that CCR program permits should be fixed at a five-year period, as provided in 329 IAC 10-13-3. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The new CCR permitting rule at 329 IAC 14 will follow a five-year permit period consistent with other permitting programs such as the current restricted waste site rules, under which current CCR landfills are permitted.
Comment: Commenters state that all inactive surface impoundments, at active or inactive generating facilities, which contain CCR and have CCR in contact with groundwater or have CCR likely to be in contact with groundwater, or that have CCR in contact with surface water, should be considered as subject to 40 CFR 257, Subpart D and Indiana's CCR permit program rule. More broadly, all current and former CCR disposal units at a power plant site should be subject to the monitoring and cleanup standards in 40 CFR Part 257, Subpart D. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: Closure for CCR units under the federal rule at 40 CFR 257, Subpart D, and the new state rule at 329 IAC 14, is required for all sites that meet the applicability requirements but does not extend beyond those requirements. The existing state rules at 329 IAC 10 may also apply to certain CCR sites.
Comment: Commenters assert that beneficial use of CCR should be defined as only those uses that encapsulate the CCR and prevent its contact with water. Use of CCR as structural fill in any application, whether in closing surface impoundments or landfills, construction or roadway fills, or other unencapsulated uses, should be prohibited. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: The beneficial use of CCR sites will be allowed according to the requirements under the federal rule at 40 CFR 257, Subpart D, and the new state rule at 329 IAC 14.
Comment: Commenters state that boron should be added to the list of Appendix IV constituents found in 40 CFR Part 257, Subpart D, for the purposes of the CCR permit program rule. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: Boron will be added to the list of constituents in the new state rule at 329 IAC 14 and will be consistent with the federal rule at 40 CFR 257, Subpart D.
Comment: Commenters state that the existing MSWLF requirements should incorporate the fugitive dust criteria of 40 CFR 257, Subpart D to minimize coal ash from becoming airborne at the facility. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters state that the existing MSWLF requirements should incorporate the liner design and leachate collection and removal system criteria of 40 CFR 257, Subpart D for new and expanded municipal solid waste landfills to prevent the leaching of coal ash contaminants into groundwater. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters request that the existing MSWLF requirements incorporate the relevant groundwater monitoring and corrective action requirements of 40 CFR 257, Subpart D to ensure that releases of coal ash contaminants are promptly detected and remediated. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters state that the existing MSWLF requirements should require municipal solid waste landfills to evaluate coal ash for waste compatibility and placement by establishing a " CCR acceptance plan" maintained in the facility operating record that ensures the facility is aware of the physical and chemical characteristics of the coal ash and handles it with the additional precautions necessary to avoid dust, maintain structural integrity, and avoid compromising the gas and leachate collection systems of the landfill so that human health and the environment are protected. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters request that the existing MSWLF requirements include public notifications to ensure impacted communities are able to access groundwater monitoring data, inspections, and other compliance documents. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters request that the existing MSWLF requirements include weekly and annual inspections of municipal solid waste landfills receiving coal ash and require owners and operators to remedy all deficiencies found during landfill inspections. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters stated that the existing MSWLF requirements should restrict the siting of new municipal solid waste landfills and lateral expansions to ensure the placement of coal ash above the uppermost aquifer. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Comment: Commenters request that the existing MSWLF requirements incorporate environmental justice into permitting activities for municipal solid waste landfills that receive coal ash to the greatest extent practicable. This should include requiring permitting agencies:
• to identify and address disproportionately high and adverse human health or environmental effects of coal ash disposal on minority populations and low-income populations;
• to employ tools to avoid or reduce potential environmental justice effects, including increasing public involvement; and
• to consider cumulative impacts of waste disposal on already over-burdened communities. (EJ), (HEC), (CAC), (SCHC), (JTNI)
Response: Amending the requirements for MSWLFs is not within the scope of this rulemaking. It is acceptable for CCR waste to be disposed of in a permitted MSWLF per the applicability requirements in the federal rule at 40 CFR 257, Subpart D, and 329 IAC 10.

Sec. 5. (a) The owner or operator of a CCR unit must follow the closure and post-closure requirements in 40 CFR 257.100 through 40 CFR 257.104*, as revised by subsections (b) through (f).

(b) In 40 CFR 257.100 through 40 CFR 257.104*, the following phrases are replaced with "and approval from the commissioner.":
(1) "Or approval from the Participating State Director or approval from EPA where EPA is the permitting authority.".
(2) "Or an approval from the Participating State Director or an approval from EPA where EPA is the permitting authority.".

(c) The following revisions are made to 40 CFR 257.102*:
(1) Add to 40 CFR 257.102(a), "Closure of a CCR unit may be completed using the partial excavation method as an alternative permitted under (e)(3) of this section and as described in 329 IAC 14-3-5(c)(6).".
(2) Add the following to 40 CFR 257.102(b)(1):
(A) "In addition, if the closure of the CCR unit will be accomplished using the partial excavation method, a description of the procedures to remove the CCR, visible stains, and one (1) foot of underlying soils; a description of the backfill and final cover system; and the methods and procedures to be used to install the backfill and final cover to accomplish closure.".

(C) "The closure cost estimate must include a ten percent (10%) contingency cost on the total estimated closure cost.".
(3) Replace the language in 40 CFR 257.102(b)(2)(ii) with "New CCR landfills, new CCR surface impoundments, any lateral expansion of a CCR unit, and overfills. The owner or operator must prepare an initial written closure plan consistent with the requirements specified in paragraph (b)(1) of this section and submit it with the permit application.".
(4) Replace the language in 40 CFR 257.102(c) with "Closure by removal of CCR (Clean Closure). An owner or operator may elect to close a CCR unit by removing and decontaminating all areas affected by releases from the CCR unit. CCR removal and decontamination of the CCR unit are complete when constituent concentrations throughout the CCR unit and any areas affected by releases from the CCR unit have been removed to concentrations at or below those determined for background unaffected by facility activities, and groundwater monitoring concentrations do not exceed the groundwater protection standard established in accordance with 40 CFR 257.95(h)* for constituents listed in 40 CFR 257, Appendix IV*. Closure under paragraph (d) of this section must comply with the following performance standards:

(B) Remove or permanently plug all pipe connections to CCR impoundments.
(C) Collect a minimum of three (3) confirmational samples per acre from the CCR unit.
(D) Collect background samples at areas unaffected by facility activities. Background samples must accurately represent in-situ soils that have not been affected by leakage from a CCR unit or facility activities that may contribute constituents of concern against which confirmational sample comparisons occur. Acquisition of background samples at similar depths below the ground surface as those attained for confirmational samples may assist in sample acquisition of similar soil lithologies for both sample types.
(E) Analyze 40 CFR 257, Appendix IV*, as amended in this article, constituents at all sample locations. All confirmational and background samples must be individually analyzed and not composited.
(F) Individually compare confirmational sampling results to background concentrations. If the facility utilizes statistically determined background concentrations, the statistical analyses must calculate upper tolerance limits at a ninety-five percent (95%) level of confidence using a statistical test method that meets the performance standards of 40 CFR 257.93(g)*. If confirmational sampling results exceed background concentrations, additional soil removal may be necessary until results are at or below background concentrations. Alternatively, the facility may attempt to supplement the background concentrations by performing additional background sampling and analysis and utilize those results in the statistical calculations.
(G) Provide an evaluation of sampling results; photographic evidence of removal of all CCR and visually stained soils; and documentation of the chosen disposal method of CCR, soil, and any other contaminated media in a clean closure certification report. A qualified professional engineer must certify in the report that all CCR and any underlying stained soil have been removed and that an additional one (1) foot of underlying soil has been removed.".

(v) prevent the probability of future impoundment of water, sediment, or slurry;
(vi) include measures that provide for slope stability to prevent the sloughing or movement of the final cover system during the closure and post-closure care period;
(vii) include erosion control measures; and
(viii) a vegetative layer must overlay the soil cover. This layer must consist of at least six (6) inches of earthen material capable of sustaining vegetation.
(B) The following applies to all final cover systems:
(i) The maximum projected erosion rate of the final cover must be not more than five (5) tons per acre per year.
(ii) The final cover must have a slope of not less than five percent (5%) and not greater than thirty-three percent (33%).
