With this latest EPA insight into groundwater monitoring, corrective action, impoundment and landfill closures, legacy sites and beneficial use, there are significant implications that may affect the entire regulated community. Taking steps to understand these potential implications\/risks and identifying solutions now can help strengthen your position for future CCR compliance and ongoing facility operations.<\/p>\n<h2>Regulatory Overview<\/h2>\n<p>On January 11, 2022, the EPA issued its\u00a0<a href=\"https:\/\/www.epa.gov\/newsreleases\/epa-takes-key-steps-protect-groundwater-coal-ash-contamination\" target=\"_blank\" rel=\"noopener\">initial written responses<\/a>\u00a0to four of the 57 Part A Applications (Part A Applications) to extend the cease receipt date of April 11, 2021, for unlined surface impoundments to receive CCR and non-CCR wastewaters. These four Part A Applications and EPA\u2019s responses were out for Public Comment which ended March 25th. For three of the four Part A Applications, EPA has proposed to deny the extension to continue receiving CCR and non-CCR wastewaters and instead issue a cease receipt of waste date of 135 days after the final determination. At the same time, EPA also issued Compliance Letters to four other facilities regarding their compliance with the Code of Federal Regulations (CFR), 40 CFR, Part 257 CCR regulations (Rule), and issued a Press Release describing EPA\u2019s actions and potential paths forward.<\/p>\n<p>In addition to facilities potentially closing due to a lack of disposal capacity (following denial of the Part A Applications\/Alternate Closure Deadlines), the potential implications of EPA\u2019s interpretations of the Part 257 regulations will be significant in a number of other areas as well.<\/p>\n                <\/div>\n                <div class=\"col-lg-4 columns js-animated-content animated-content\">\n                                        <div class=\"wysiwyg__links js-animated-content animated-content\">\n                        <div class=\"wysiwyg__links__top \">\n                                                        <h4>Related Services<\/h4>\n                                                                                    <ul class=\"js-animated-content animated-content\">\n                                                                <li><a href=\"https:\/\/www.trccompanies.com\/services\/remediation-and-materials-management\/coal-ash-management\/\" target=\"_self\">Coal Ash Management<\/a><\/li>\n                                                            <\/ul>\n                                                    <\/div>\n                                                                                                            <div class=\"wysiwyg__links__bottom\">\n                                    <a href=\"https:\/\/www.trccompanies.com\/services\" target=\"_self\">View All Services<\/a>\n                                <\/div>\n                                                                                                <\/div>\n                <\/div>\n                    <\/div>\n\n            <\/div>\n<\/section>\n<!-- End Block: acf\/wysiwyg -->\n\n<!-- Start Block: acf\/wysiwyg -->\n\n<section class=\"wysiwyg section-padding bg-white-fog\">\n    <div class=\"container-fluid\">\n                    <div class=\"wysiwyg__wrapper\">\n        \n        <div class=\"row\">\n                        <div class=\"col-lg-12\">\n                                                                                    <div class=\"option-links\">\n                            <ul>\n                                                                                                        <li>\n                                        <a href=\"https:\/\/www.trccompanies.com\/services\/remediation-and-materials-management\/coal-ash-management\/\" \n                                        target=\"_blank\">\n                                        Coal Ash Management                                        <\/a>\n                                    <\/li>\n                                                                                                <\/ul>\n                        <\/div>\n                                            \n                                                <\/div>\n\n                            <div class=\"col-lg-12 js-animated-content animated-content\">\n                    <h2>Key Closure\/Groundwater and Other Compliance Issues<\/h2>\n<p>EPA\u2019s key policy interpretations and existing Rule compliance expectations around groundwater and closure issues include:<\/p>\n<ul>\n<li>Closure plans must detail how the closure standards will be met under the Rule, taking into consideration the below interpretations:\n<ul>\n<li>CCR units (impoundments and landfills) cannot close in-place (CIP) with CCR in contact with groundwater.<\/li>\n<li>Free liquids that must be addressed prior to CIP include both freestanding liquids (e.g., surface water), as well as all separable porewater, including sluiced water and groundwater.<\/li>\n<li>Infiltration includes potential vertical infiltration at ground surface, as well as horizontal and upward infiltration from the base, including groundwater.<\/li>\n<li>Schedule changes, design changes, etc. need to be updated in the closure plan and reposted on the website with amendments made 60 days ahead of a planned change.<\/li>\n<\/ul>\n<\/li>\n<li>Deficiencies with the groundwater monitoring systems, including well locations, number of wells, spacing, etc., and that an accurate characterization of hydrogeologic conditions (i.e., a well-developed Conceptual Site Model (CSM) based on site-specific data) is necessary to properly address these requirements. This also includes a justification of the use of the minimum of one upgradient and three downgradient wells.<\/li>\n<li>PE certification of the monitoring network requires an evaluation of site-specific conditions and an explanation as to how the monitoring network meets the requirements, including justifying and updating documents when changes are made to the monitoring network.<\/li>\n<li>Deficiencies with the Annual Groundwater Monitoring and Corrective Action (GWMCA) Reports, and the lack of appropriate information therein to support.<\/li>\n<li>Deficiencies with Alternate Source Demonstrations (ASD\u2019s), including the lack of site-specific facts and data support the ASD (insufficient lines of evidence).<\/li>\n<li>Monitored natural attenuation (MNA) for inorganic constituents (e.g., metals) cannot rely on dispersion and dilution as a primary MNA mechanism.<\/li>\n<li>Remedy selection was not performed in a timely manner (as soon as feasible) based on the results of the Assessment of Corrective Measures (ACM) evaluation.<\/li>\n<\/ul>\n<p>In addition to the closure and groundwater regulatory interpretations, EPA also noted :<\/p>\n<ul>\n<li>Units closing for cause (e.g., unlined surface impoundments) cannot place CCR in the unit, even if for beneficial use.<\/li>\n<li>Placement of CCR, including for beneficial use, in an inactive unit not previously subject to the Rule, makes the unit active and subject to the Rule.<\/li>\n<li>Legacy impoundments (inactive impoundments at inactive sites) may become \u201cexisting CCR surface impoundments\u201d, per the regulatory definition, and subject to the closure requirements if they receive CCR after the effective date of the Rule (October 19, 2015).<\/li>\n<li>Impoundments that closed prior to the Rule and were not subject to the regulations, but still contain or impound liquid, including groundwater in contact with CCR, may be considered an \u201cinactive impoundment\u201d and subject to the Rule.<\/li>\n<li>Concrete settling tanks may be considered CCR surface impoundments, particularly if it is sub-grade, it is considered to be in a constructed depression, and must meet requirements of the Rule, including groundwater monitoring requirements.<\/li>\n<\/ul>\n                <\/div>\n                                <\/div>\n\n                    <\/div>\n            <\/div>\n<\/section>\n<!-- End Block: acf\/wysiwyg -->\n\n<!-- Start Block: acf\/innerpage-accordion -->\n<section class=\"fx-accordion js-accordion section-margins\">\n    <div class=\"container-fluid\">\n        <div class=\"fx-accordion-flex\">\n                        <div class=\"fx-accordion-top-content js-animated-content animated-content\">\n                <div class=\"fx-accordion-top-content__inner\">\n                    <h2>Action Plan for the Regulated Community<\/h2>\n<p>Because the EPA Part A Application and Compliance Letter comments and draft determinations referenced the regulatory citations under Part 257, all regulated facilities\/units (and many currently unregulated units) could become subject to the final determinations. Several of the EPA comments highlight the importance of hydrogeological site characterization and making sound judgements and conclusions backed by supporting data. Many of these interpretations, especially those regarding closure and groundwater issues, are inconsistent with the regulated community\u2019s understanding of the CCR requirements, and in some cases conflict with the original CCR Rule.<\/p>\n<p>While these initial determinations will be worked out through the Public Comment period, EPA\u2019s final determinations and anticipated future litigation, regulated entities may wish to consider preemptive positioning to evaluate their potential risk\/liability. Some of these implications (e.g., CIP with CCR in contact with groundwater) can have significant monetary and operational impacts for past, ongoing and future pond and landfill closures, including plant closures, as well as consideration for future site use and transactional challenges. There are several key areas and practical solutions that can be evaluated\/implemented to identify potential risks and strengthen your position in demonstrating compliance with the Rule including:<\/p>\n                <\/div>\n            <\/div>\n                                    <div class=\"fx-accordion-right\">\n                <div class=\"fx-accordion__panels js-animated-content animated-content\">    \n                                        <article class=\"fx-accordion__panel js-accordion-item icon--collapse\" data-accordion-id=\"0\">\n                        <button class=\"fx-accordion__panel__toggle js-accordion-headline\" type=\"button\" data-accordion-id=\"0\">New CCR Units<\/button>    \n                        <div class=\"fx-accordion__panel__content\">\n                            <p>Identify potential closed units or legacy ponds that could become subject to the Rule, based on the above EPA interpretations.<\/p>\n                                                    <\/div>\n                    <\/article>\n                                        <article class=\"fx-accordion__panel js-accordion-item\" data-accordion-id=\"1\">\n                        <button class=\"fx-accordion__panel__toggle js-accordion-headline\" type=\"button\" data-accordion-id=\"1\">Document Audit<\/button>    \n                        <div class=\"fx-accordion__panel__content\">\n                            <p>Evaluate your CCR Website to ensure all documents required by the Rule are posted and have been updated in accordance with the Rule, especially the GWMCA Reports, Closure and Post Closure Plans.<\/p>\n                                                    <\/div>\n                    <\/article>\n                                        <article class=\"fx-accordion__panel js-accordion-item\" data-accordion-id=\"2\">\n                        <button class=\"fx-accordion__panel__toggle js-accordion-headline\" type=\"button\" data-accordion-id=\"2\">Risk Analysis and Data Gaps<\/button>    \n                        <div class=\"fx-accordion__panel__content\">\n                            <p>Review existing documents through EPA\u2019s lens\/comments, especially ACM\u2019s, ASD\u2019s and lines of evidence, GWMCA\u2019s Reports, Closure\/Post Closure Plans and selected groundwater corrective actions to evaluate potential shortfalls, potential corrective actions and ease of implementation, and associated costs.<\/p>\n                                                    <\/div>\n                    <\/article>\n                                        <article class=\"fx-accordion__panel js-accordion-item\" data-accordion-id=\"3\">\n                        <button class=\"fx-accordion__panel__toggle js-accordion-headline\" type=\"button\" data-accordion-id=\"3\">Independent Third-Party Review of Key Groundwater and Closure Plan Issues<\/button>    \n                        <div class=\"fx-accordion__panel__content\">\n                            <ul>\n<li><em>Groundwater Monitoring Plan:<\/em>\u00a0Evaluate the basis for your Groundwater Monitoring Plan (GMP), including well locations, number of wells, etc. and ensure you have a solid justification, including a robust CSM that demonstrates the site geology and groundwater flow is well-understood, to support the GMP.
