Brine Solidification And Metals Sequestration Using Lignocellulosics, Frank Kvietok
Brine Solidification And Metals Sequestration Using Lignocellulosics, Frank Kvietok
World of Coal Ash Proceedings
Coal ash has historically been used as a convenient, on-site solidification material for brines generated from flue gas desulfurization at power plants. As alternate utilization scenarios are developed for coal ash, lignocellulosic (wood-based) sorbents can serve as a highly efficient substitute for the solidification process. Results will be shared for a variety of different brine types: thermally reduced, thermally reduced and neutralized, and reverse osmosis. In addition to solidification performance, which demonstrated a 3-4x mass of liquid vs mass of sorbent factor, studies were conducted to quantify the strength of binding to the wood-based sorbent for a broad range of …
Practical Guidelines For Pump Testing Of Ccr: Workflow, Design, And Lessons Learned., Nathanial Keller, Brian Hennings, Vic Modeer, Katie Moran
Practical Guidelines For Pump Testing Of Ccr: Workflow, Design, And Lessons Learned., Nathanial Keller, Brian Hennings, Vic Modeer, Katie Moran
World of Coal Ash Proceedings
This session presents a streamlined approach for pump testing of coal combustion residuals (CCR) to maximize hydraulic information with limited well installations, variable pumping rates, and short tests. Pre-test forward modeling identifies well offsets (typically 5–10 ft) and test durations (~2–6 hours) to yield measurable and analyzable drawdown at observation wells despite low pumping rates. Field execution consists of short step-drawdown testing to evaluate well specific capacity and select pumping rates for a constant rate test with one or more observation wells. Test results facilitate analysis of transmissivity and storativity of the CCR. Applied at two Midwestern sites with different …

Simplified Approximate Procedure For Assessing The Implications Of Updated Usgs Seismic Hazard Models On Seismic Stability Assessments Of Ccr Impoundment Facilities, Nick Mcclung, Matt Bishop, Adrian Pena-Iguaran, Seda Gokyer-Erbis
World of Coal Ash Proceedings
Selection of appropriate seismic design ground motions remains a key challenge for seismic stability assessments of coal combustion residual (CCR) impoundment facilities, particularly where regulatory guidance does not specify a required hazard model. This paper examines the implications of using Uniform Hazard Spectra (UHS) derived from the 2014 versus the 2018 U.S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) for seismic amplification and stability evaluations of the Tennessee Valley Authority (TVA) Widows Creek Fossil (WCF) Plant CCR Management Units. The 2018 NSHM incorporates updated understanding of seismicity in the central and eastern United States and generally predicts higher ground …
Integrating Advanced Geochemical Workflows With Modern Statistical Tools To Improve The Decision-Making Process At Ccr Sites, A Case Study, Glenna Thomas
World of Coal Ash Proceedings
While statistical assessment provides the foundation for CCR compliance reporting, incorporating a holistic geochemical framework transforms statistics from a compliance requirement into a powerful predictive tool. Strategic geochemical insight established the basis of understanding needed to support successful statistical approaches and to ensure that statistical outcomes reflect actual groundwater behavior. Whether it is trend analysis, delineating source mechanism, or updating geochemical conceptual site models (GCMs), geochemical context provides the technical foundations for statistical outputs and methods. A continuously refined GCSM enhances the ability to anticipate how groundwater chemistry should evolve, improving interpretation and predictive capability. This allows practitioners to understand …
Before The Limit Hits: Lessons From A Proactive Construction Air Monitoring Program, Brian Egan, Nicholas Golden, Wendy Depp
Before The Limit Hits: Lessons From A Proactive Construction Air Monitoring Program, Brian Egan, Nicholas Golden, Wendy Depp
World of Coal Ash Proceedings
This presentation describes a comprehensive air monitoring program designed to protect workers and nearby neighborhoods during ash pond closure work. The program uses three main components: project (or boundary) monitoring at the site perimeter to track dust near the project boundaries, work area monitoring placed near active construction zones, and personal sampling on individual workers at regular intervals. Together, these approaches provide data on both community impacts and worker exposures, helping the team respond quickly when levels approach action limits. The Teams actions prior to exceedance of regulatory limits has helped prevent exposures. The talk will explain how monitors are …
Monitored Natural Attenuation Evaluation And Additional Characterization Of A Ccr Unit Lithium Groundwater Plume, Matt Barickman, Adam Piestrzeniewicz Pg
Monitored Natural Attenuation Evaluation And Additional Characterization Of A Ccr Unit Lithium Groundwater Plume, Matt Barickman, Adam Piestrzeniewicz Pg
World of Coal Ash Proceedings
Monitored Natural Attenuation (MNA) refers to the reliance on natural attenuation processes (within the context of a carefully controlled and monitored site cleanup approach) to meet groundwater protection standards (GPS) for a CCR unit within a reasonable time frame (USEPA, 1999). MNA is being evaluated as an adaptive management strategy for a CCR unit groundwater plume with statistically significant lithium concentrations above GPS, though with little risk of offsite migration. A previous MNA evaluation was performed for the lithium plume following the United States Environmental Protection Agency (USEPA) “tiered lines of evidence approach” (USEPA, 2015), which determined that there were …

Artificial Intelligence Challenge To Strategic Assessment Organizations, Thomas J. Welch
Naval War College Review
As artificial intelligence—particularly agentic artificial intelligence—continues to evolve, defense strategists must understand its capabilities and limitations. Emerging technologies will impact established frameworks, practices, and rhythms, and strategic-assessment organizations in particular must maximize efficiency while preserving the human elements that are indispensable to strategic planning.

Naval War College Review
With artificial intelligence—cyber’s offspring—come several risks and vulnerabilities that must be defended against. The key to defense, as always, is having the right personnel in place to build resilience into the mission. To distribute critical manning assets correctly, skill-needs rubrics are well suited to ensure that the proper personnel are on hand to defend systems and execute critical missions.

Understanding The 2024 Legacy Rule Risk Assessments, Ishita Shrivastava, Ari Lewis, John Kondziolka, Andrew Bittner
World of Coal Ash Proceedings
The United States Environmental Protection Agency's (US EPA's) May 2024 Legacy Coal Combustion Residuals (CCR) Rule aims to address potential releases and associated risks from legacy surface impoundments and CCR management units (CCRMUs) that were not regulated under the 2015 CCR Rule. As part of the 2024 rule, US EPA conducted several risk analyses to quantify risks from historical disposal units and CCRMU fills. For historical units, US EPA relied on modeling results for “previously excluded” units from the 2014 CCR Risk Assessment. For CCRMU fills, however, US EPA performed new modeling that incorporated several different assumptions relative to the …
Establishing Groundwater Monitoring Systems Under The Legacy Rule: A Systematic Approach For Utilities, Chris Hoglund
Establishing Groundwater Monitoring Systems Under The Legacy Rule: A Systematic Approach For Utilities, Chris Hoglund
World of Coal Ash Proceedings
The USEPA’s Legacy CCR Rule introduces new requirements for establishing groundwater monitoring systems at Legacy Surface Impoundments (LSIs) and Coal Combustion Residual Management Units (CCRMUs). These requirements present unique challenges for electric utilities, particularly at inactive or historically operated facilities where subsurface data are limited and CCR units may have nontraditional configurations such as linear roadways, elongated embankments, or distributed disposal areas. Utilities must also determine how best to apply single-unit or multi-unit monitoring approaches, integrate newly regulated units into existing monitoring networks, and align monitoring system design with planned closure strategies. This presentation outlines a systematic, defensible framework to …
Risk Evaluation Of Linear Coal Combustion Residual Management Unit (Ccrmu) Fills, Qian Zhang, Andrew Bittner, John Kondziolka, Masoud Arshadi
Risk Evaluation Of Linear Coal Combustion Residual Management Unit (Ccrmu) Fills, Qian Zhang, Andrew Bittner, John Kondziolka, Masoud Arshadi
World of Coal Ash Proceedings
In 2024, the US Environmental Protection Agency (US EPA) established new regulations for coal combustion residual management units (CCRMUs), defined as coal combustion residual (CCR) deposits placed on power plant properties outside of landfills or surface impoundments. US EPA supported the rulemaking with modeling-based risk analyses and established regulatory requirements based on fill size. Linear CCRMU, such as backfill along pipelines or haul roads, have individual segments that may be composed of a small amount of mass below the threshold for regulation, but the cumulative mass over the full linear feature extent may exceed regulatory thresholds. This study applies US …
Application Of Mine Tailings Flow Failure Assessment On Ccr, Zachary Fallert
Application Of Mine Tailings Flow Failure Assessment On Ccr, Zachary Fallert
World of Coal Ash Proceedings
A new geotechnical stability analysis method has been implemented for a CCR surface impoundment to aid in design for temporary cut slopes and final closure grades. Conditions have come to light after significant tailings dam failures occurred across the globe, specifically those exhibiting flow failures (i.e. failures in which tailings behave a liquid and flow out of the facility). These failures have come under intense scrutiny as the failures pose significant risk to public safety and the environment and have been observed in CCR. Additionally, static liquefaction has arisen as another potential but less well understood causative mechanism. As the …

Lessons Learned: Commissioning An Fgd Wastewater Treatment System, Bella Triolet, Mckale Grant, Louis Manigault
Lessons Learned: Commissioning An Fgd Wastewater Treatment System, Bella Triolet, Mckale Grant, Louis Manigault
World of Coal Ash Proceedings
Stantec recently supported commissioning a flue gas desulfurization (FGD) Wastewater Treatment System in accordance with the 2020 Environmental Protection Agency (EPA) Effluent Limitations Guidelines (ELG) Rule, which requires that coal fired power plants meet their more stringent requirements by December 31, 2025. With the addition of the 2024 EPA ELG Rule, coal fired power plants will now be expected to move to zero liquid discharge (ZLD) systems or permanently cease coal combustion by 2034. Due to this change, it is likely that coal fired power plants will be looking to design and install ZLD systems within the next decade. While …
