H1.2 Case Study – Characterization and Remediation of CCR-Impacted Groundwater
(8:20 am – 8:40 am PDT)
(11:20 -11:40 am EST)
H2.2 Case Study - Characterization and Remediation of CCR-Impacted Groundwater
High resolution site characterization (HRSC) of groundwater downgradient of a suspected CCR impoundment release was performed using multiple tools to evaluate CCR groundwater impacts and serve as the basis for selecting and designing a groundwater remedy. HRSC at this CCR facility included: 1) surface geophysical surveys using electrical resistivity imaging (ERI) around CCR impoundments to evaluate zones of elevated specific conductivity as an indicator of CCR groundwater impacts; and 2) direct push technology (DPT) investigations for collection of relative hydraulic conductivity, real-time vertical profiles of electrical conductivity (EC), and depth-discreet groundwater samples. Once a conceptual site model was developed, a groundwater extraction system was designed, constructed, and brought online to address identified CCR impacts. The remedial system included installation of nine extraction wells with a total flow rate up to 250 gallons per minute. Due to concentrations of groundwater constituents, corrosion/scaling issues were predicted by geochemical modeling and subsequently observed during system operation. The potential for scaling was addressed through system design and as part of routine system operation/maintenance. Since system startup, routine groundwater monitoring indicates substantial declines in groundwater concentrations.

H1.3 Characterization of CCP Impoundments to Determine Beneficial Uses
(8:40 am – 9 am PDT)
(11:40 am – 12 pm EST)
H2.5 Characterization of CCP Impoundments to Determine Beneficial Uses
The continuing decline of coal utilization for energy production has resulted in a limited and declining supply of CCPs for beneficial use applications. In order to meet growing market demand and mitigate environmental risk, harvesting of impounded CCPs for beneficial use is becoming an increasingly desired solution. In order to fully evaluate the risks, beneficiation opportunities, and economic value of CCP ponds and landfills, the impoundments must be strategically characterized before harvesting. In this presentation, the methods by which a CCP impoundment can be characterized will be reviewed. In general, one of the first steps is engineering a sample plan informed by pond or landfill profile and any known historical data related to the development of the site. Test methods are then selected for the samples in order to evaluate material characteristics that impact specific beneficial use opportunities. Impoundment profiles are then generated to give a comprehensive understanding of the in-situ CCP material.

H1.5 Practical CCR Management Using Lime
(9:20 am – 9:40 am PDT)
(11:20 – 11:40 am EST)
H2.6 Practical CCR Management Using Lime
Lime is an increasingly popular solution for efficient coal combustion residue (CCR) management and closure programs. This presentation highlights the ability of Lhoist products to chemically alter the structure of ponded ash for robust solidification. More specifically, modest quantities of lime predictably render the ash more friable, forgiving, and easier to handle using standard equipment. The flexibility that lime treatment offers over competitive systems, allows contractors to reliably meet project deadlines and reduce costs. Additionally, closure-in-place projects using lime stabilization are viable options and an area where Lhoist has over 50 years’ experience in stabilization of pozzolanic materials.

H1.1 Low Capital Cost FGD ELG Compliance Strategy
(8:00 am – 8:20 am PDT)
(11 am – 11:20 am EST)
H2.1 Low Capital Cost FGD ELG Compliance Strategy
“Treat-and-Discharge” is the most common form of Flue Gas Desulfurization (FGD) wastewater disposal. This method may no longer be available to some coal fired power plants due to the recently revised Flue Gas Desulfurization (FGD) Effluent Limitation Guidelines (ELG) regulations. The remaining operating life of many coal fired power plants is now relatively short, therefore, many operators are searching to find FGD ELG compliance strategies that can be instituted without major capital outlays. Softening + membrane concentration + solidification is a low capital cost approach being considered by many coal plant operators to comply with the revised FGD ELG regulations. Many coal fired power plants have existing physical / chemical treatment systems installed to precipitate heavy metals. These existing treatment systems can be easily modified to include softening at low cost. The softened FGD wastewater volume can be reduced using membrane technology (ultrafiltration + reverse osmosis). Reverse osmosis (RO) recoveries of 70 to 90% may be achievable resulting in a 3 to 10 times brine volume reduction and thus a proportional decrease in solidification reagent and disposal needs. An added benefit is that the RO permeate can be recycled for plant reuse. Solidification consists of readily available, off-the-shelf equipment including silos, mixers, and conveyors.
H3.2 Reduce CO2 Capture Footprint and Costs Through Process Intensification
(1:20 pm – 1:40 pm PDT)
(4:20 pm – 4:40 pm EST)
H4.2 Reduce CO2 Capture Footprint and Costs Through Process Intensification
The major hurdles to adoption of CO2 capture from power stations are the equipment size and capital cost of the carbon capture system. Carbon Clean is developing a compact integrated carbon capture system that uses rotating packed bed (RPB) units to drive down CapEx and footprint. This presentation discusses the equipment size reduction anticipated with RPB-based process intensification. Also, a rough order-of-magnitude economic analysis will be provided to compare the expected capital and operating costs reductions for the intensified process versus a benchmark monoethanolamine (MEA) based static system.

SESSION H2. CCR MANAGEMENT & GROUNDWATER REMEDIATION OCTOBER 26, 2021
H2.1 In Situ Flushing – A Counter-Intuitive Groundwater Remedy at CCR Sites
(10:30 am – 10:50 am PDT)
(1:30 pm – 11:50 pm EST)
H3.1 In Situ Flushing - A Counter-Intuitive Groundwater Remedy at CCR Sites
Many coal combustion residuals (CCR) disposal units regulated by the Federal CCR Rule will require Corrective Actions as statistically significant levels (SSLs) of Appendix IV constituents are detected above groundwater protective standards (GWPS) during Assessment Monitoring. The CCR Rule imposes stringent performance standards for Corrective Actions with the point of compliance (POC) at the edge of the CCR unit. Pump and treat (P&T) technologies might be necessary, or already in place, at some of these facilities. However, traditional P&T technologies are limited in their capacity to address unsaturated zones and lower permeability areas containing residual pore water with dissolved and sorbed constituent mass, such as between capped CCR units and the lowered groundwater table induced by pumping. When P&T systems are shut off and the groundwater table rebounds, these unsaturated zones and lower permeability areas may act as secondary sources of constituents to groundwater which could lead to detections above GWPS and additional Corrective Actions. Unlike traditional P&T technologies, in situ flushing targets unsaturated zones and lower permeability areas with clean water injection wells that mobilize residual pore water with constituent mass toward capture wells. In situ flushing has recently been embraced at a large CCR disposal site to mitigate unsaturated zones and lower permeability areas below CCR units from acting as secondary sources after P&T systems are shut off.
H 2.2 Geochemical Modeling for CCR Remedy Selection
(10:50 – 11:10 am PDT)
(1:50 pm – 2:10 pm EST)
H3.3 Geochemical Modeling for Defensible CCR Remedy Selection
Power clients across the US are challenged to properly weigh corrective measures for CCR management. A favored approach among stakeholders is “clean closure”, i.e. source removal. However, the long-term environmental consequences of CCR removal are rarely investigated. Here, we present a case-study integrating groundwater and geochemical modeling at multiple CCR sites. Multiple models were developed for a variety of corrective actions, including natural attenuation, semi-permeable caps, barrier wall emplacement, geochemical conditioning, and source removal. The modeling results were used to evaluate the long-term potential for success and identify the environmental consequences of each corrective measure, including CCR removal.

H2.3 Insurance Coverage for CCR Investigation and Remediation
(11:10 am – 11: 30 am PDT)
(2:10 pm – 2:30 pm EST)
H3.4 Insurance Coverage for CCR Investigation and Remediation Costs
Insurance policies may provide utilities with significant funding for CCR-related investigation and remediation costs. In particular, a utility’s historical liability policies purchased decades ago may pay for the property damage (including contamination of soil and groundwater) that has occurred. Our presentation will identify key issues relating to insurance recovery for CCRs, answer common questions, and offer tips from our decades of experience helping utilities secure coverage for environmental claims.

H2.4 Performance of Engineered Turf Cover Under Extreme Weather Conditions
(11:30 am – 11:50 am PDT)
(2:20 pm – 2:50 pm EST)
H3.5 Performance of Engineered Turf Cover Under Extreme Weather Conditions
The engineered turf cover system uses an engineered synthetic turf infilled with sand to cover and protect the underlying geomembrane. Since the first installation in 2009, the engineered turf cover system has been increasingly used for closure of MSW and industrial landfills and CCR impoundments. This presentation starts with a brief introduction of the system components and functions. The remainder of the presentation is focused on the performance of the cover system related to soil erosion, water quality, and geotechnical stability under extreme weather conditions (e.g., hurricanes, storms, high winds and freezing temperatures) through documented laboratory test results and field observations.
H3.1 In Situ Impoundment Closure and Groundwater Corrective Action Technology
(1:00 pm – 1:20 pm PDT)
(4 pm – 4:20 pm EST)
H4.1 In Situ Impoundment Closure and Groundwater Corrective Action Technology
An in-situ closure method utilizing discrete in situ solidification (ISS) will be presented. ISS when utilizing this method will provide an environmentally sound and cost-effective closure/corrective action of CCP impoundments as compared to other alternatives. This technology eliminates leaching and increases geotechnical stability reducing long term risk. The ash is hydraulically isolated from the groundwater by constructing a horizontal hydraulic barrier at the bottom of the impoundment and a perimeter wall around the impoundment thereby eliminating contact with groundwater. These demonstrated ISS applications will also enhance geotechnical stability and reduce slope failure. Advantages of this closure/remediation method will be presented.

H2.6 CCR beneficiation -fly ash to produce eco-friendly low-cost durable concrete
(8:40 am - 9 am PDT)
(11:40 am - 12 pm EST)
H2.6 CCR beneficiation -fly ash to produce eco-friendly low-cost durable concrete
The concrete industry is facing a shortage of low-cost pozzolanic materials whereas large quantities of coal combustion residuals (CCR) remain underutilized. A significant underutilized CCR is spray dry absorber ash (SDA) with high levels of calcium sulfite/sulfate that have historically posed concerns to concrete structures due to potential sulfate attack. This presentation discusses an innovative approach that incorporates SDA with portland cement and harvested fly ash to produce eco-friendly low-cost durable concrete. Benefits include a possible 50 percent reduction in expensive portland cement that is a major contributor to a global CO2 emissions.

SESSION I1. WASTEWATER TREATMENT, ELG, CCR OCTOBER 27, 2021
I1.1 Beneficial Reuse of Flare Gas for Heavy Oil Produced Water Treatment
(8 am - 8:20 am PDT)
I1.1 Beneficial Reuse of Flare Gas for Heavy Oil Produced Water Treatment
Globally, a tremendous amount of natural gas is flared and wasted as part of oil production. Total US gas flared increased from 165,928 metal-to-metal charge transfer (MMct) in 2010 to 468,347 MMct in 2018. But what if that flare could be put to use as part of the produced water treatment process?
This presentation will review findings from a recent pilot in the Western United States where a novel thermal concentration technology successfully treated produced water on site at a heavy oil production well. The concentrator reduced the volume of produced water by 98% and thus enabled a drastic reduction in disposal costs for the operator. The final concentrate contained 48.3% solids by weight and almost 490,000 mg/L total dissolved solids (TDS) and all of the thermal energy for the treatment process was generated by flaring readily available wellhead gas. Additionally, the process was able to remove 100% of BTEX Compounds.

I1.6 Managing Outage Wash Water Treatment with Existing Infrastructure
(9:40 am - 10 am PDT)
I1.6 Managing Outage Wash Water Treatment with Existing Infrastructure
Revised Effluent Limit Guidelines (ELG) and Coal Combustion Residuals (CCR) regulations are requiring coal fired electric utilities to re-assess all of their wastewater management issues. An area often overlooked is treatment of outage wash water. Traditionally, these waters were simply directed to an ash pond for storage and treatment. With the CCR regulations requiring de-commissioning of these ponds, the outage washwater will be subject to NPDES or State mandated effluent limits prior to discharge. Existing bottom ash dewatering systems present a unique opportunity for utilities to conserve significant capital investment by temporarily repurposing these systems (with equipment and process augmentation) for treatment of outage wash waters. UCC has successfully demonstrated the implementation of BADW as outage wash water treatment systems at a large mid-western utility during its Fall, 2019 outage. UCC met NPDES effluent limits for TSS, iron, copper and pH while successfully managing the various flows generated by outage wash processes. By successfully executing this pilot, UCC has provided a technically sound alternative to investing in a large dedicated outage wash treatment system.
SESSION I2. 316(b), ELG, FGD WASTEWATER MANAGEMENT OCTOBER 27, 2021
I2.1 Design and Operation of Temporary and Permanent Low Volume WWT Systems
(10:30 am - 10:50 am PDT)
I2.1 Design and Operation of Low Volume WWT Systems
With the impending closure of ash ponds and redirection of FGD wastewater to segregated systems, the problem is to how to treat the remaining water flows from a coal fired power plant to effectively meet discharge limits. Commonly called Low Volume Wastewater (LVWW), these flows include coal pile run off, plant sumps, seal water. filter and demineralizer backwash, and various intermittent wash waters. In total, the flows can be quite high approaching 10,000 gpm. Additionally the water quality can be highly variable depending on rain events, process water cycles and cleaning events. Effective treatment requires consideration of these factors and design of a system that is robust and flexible in achieving desired performance across all variables. Additionally, the system must be compact so as to fit into the available space of an operating plant without disruption of power production. This presentation will describe the design of a LVWW for a large coal fired power plant, the provision of a temporary solution to meet required regulatory dead line, the start-up and commissioning and operation of both systems.

I2.3 Measurement, Control & Regulatory Challenges in Wastewater Biocide
(11:10 am - 11:30 am PDT)
I2.3 Measurement, Control & Regulatory Challenges in Wastewater Biocide
Accurate online measurement of total residual oxidant (TRO) or biocide is essential for achieving wastewater treatment regulatory compliance. Traditional DPD colorimetric measurement has limitations, such as higher detection limit, larger error, interference from turbidity, color, and metal ions, drift due to discoloring reagent, and intermittent batch measurement. The newly developed TRO analyzer with ion-selective electrode (ISE) technology solves these issues with significantly improved detection limit and accuracy using the EPA-approved standard method 4500-Cl I. Additionally, the ISE based measurement is continuous, free of interference, sample turbidity and color, and works in a wider dynamic range with much-lowered detection limits.

I4.2 Section 316(b) Optimization Study at Nearman Creek Power Station
The Nearman Creek Power Station, operated by the Kansas City Board of Public Utilities (BPU), is a coal-fired, 256-megawatt (MW) gross generating station located in Kansas City, Kansas. The Final Rule 316(b) Rule at § 122.21(r)(6)(i) states that if a facility chooses to comply with § 125.94(c)(5), a 2-year, site-specific Impingement Technology Performance Optimization Study will need to be conducted. The purpose of the study is to demonstrate that the operation of the modified traveling screens has been optimized and is functioning properly to minimize impingement mortality of non-fragile species. Burns & McDonnell has prepared an Optimization Study Plan, designed the temporary sampling system to collect fish and shellfish impinged off of the new traveling screens, and is completing the study with BPU. This presentation will focus on the study design (sampling equipment setup and experimental design), impingement and latent mortality sampling methods, needed ancillary data (traveling screen operational, and station data, and ambient water quality and flow data) and discuss the associated challenges in designing the temporary sampling system.
I4.3 You've Got PFAS. How to Prepare, Dispose and Respond
(4:10 pm - 4:30 pm PDT)
I4.3 You've Got PFAS. How to Prepare, Dispose and Respond
Per- and polyfluoroalkyl substances (PFAS) are emerging contaminants of concern in soil, groundwater and drinking water systems. PFAS releases have the potential to impact water supplies and are a challenge to capture and remove. Due to their chemical properties and widespread use, PFAS typically have multiple source areas and can be ubiquitous in most urban areas. For the utility industry, links and liability to the issue is through the training and use of Aqueous Film-Forming Foam (AFFF) concentrates and laydown yards which store wires which are coated in the compound. Some coal fired power plants have used AFFF either in training or for fire suppression of their coal piles for the simple fact that AFFF is extremely effective. In addition, potential liability can be from the leaching of wires that have been coated in PFAS. This presentation will provide information on some tools and approaches from simple to complex on how a facility can identify what PFAS may be associated with their use and where it has migrated based on Barr’s nearly 20 years of PFAS investigation including case studies from refining and industrial sites. This presentation will discuss how to inventory current and legacy supply of AFFF containing PFAS and replacement and disposal options. Attendees will leave the short presentation with an understanding of the complexity of the chemistry as well as an idea for approaches to audit current PFAS risk and prepare in the event of a regulatory inquiry.

SESSION I3. 316(b), COOLING TOWER OCTOBER 27, 2021
I3.2 No Phosphorous Cooling Tower Treatment
(1:20 pm - 1:40 pm PDT)
I3.2 New and Novel No Phosphorous Cooling Water Treatment
Market and regulatory demands are requiring customers to look for non or low phosphorous alternates and solutions to open recirculating cooling water treatment. Phosphorous being a key nutrient for algae growth in the towers and receiving bodies of water. Under these challenging operating conditions, new techniques were evaluated in understanding the metal surface chemistry including XPS, ToF-SIMS and TEM surface analysis yielding insights into the engineering of passivation films in cooling water applications. STP and CHO inhibitors have a significant role in the construction of passivating films and can be combined in with metals salts such as Zn, Sn, and Al3+ in challenging corrosive conditions to provide corrosion and deposition control with control over the engineering film. Combined with saturation modeling analytics the cooling tower operator can effectively model and manage a no / low phosphorous cooling water treatment programs that meets the environmental regulations while maintaining industry standard corrosion results. One customer case history will be included in the paper.

As fleet managers prepare to transition from conventional to electric vehicles, they are faced with a new set of challenges. A variety of factors such as charging management, infrastructure planning, management of energy costs, and operational transitions are creating a new set of challenges and opportunities. We present an overview of the changing nature of EV fleet deployment and discuss strategies to manage a smooth transition from conventional to electric fleets as it relates to energy management, charging infrastructure deployment and fleet operations for this new category of vehicles. This presentation is intended for fleet managers and professionals responsible for the management, operations, and maintenance of public, private, municipal and other fleets who are deploying electric vehicle fleets. The target audience also includes facility managers responsible for infrastructure and energy planning, and support and service managers in charge of maintenance operations for these fleets. This presentation focuses on strategies and tools that can be used to inform numerous aspects of EV fleet planning and deployment, addressing questions such as: - What charging capacity is optimal for the fleet based on factors such as battery capacity, route efficiency, dispatch scheduling etc? - How and where should deploy charging stations be deployed? What is the right balance between depot vs on route charging? - Which facility may be most appropriate for initial EV deployments?

J4.2 Vehicle Grid Integration - Creating Value Through Managed EV Charging
As EV adoption moves beyond small niche buyers to become increasingly mainstream, EV charging is shifting focus from a customer-focused topic to topics addressing the impact to the grid. As highly concentrated charging of EVs can cause bottlenecks, overloading and inefficiencies on the grid, the need to manage EV charging is a hot topic. This presentation will discuss the key value propositions, as used in electric utility regulatory filings, as well as industry leading perspectives, of key benefits from Vehicle - Grid Integration and Managed EV Charging. Using real-world use cases, the methodology, technology and key benefits will be presented, along with a discussion on recent pilot efforts in VGI.
J4.1 Dividend Account Parking: More Fairness & Transparency; Less Driving
(3:30 pm - 3:50 pm PDT)
J41 Dividend Account Parking: More Fairness & Transparency; Less Driving
Bundled-cost and bundled-benefit car-parking systems (erroneously called “free”) are defined, showing that they are not free and that they increase the drive-alone mode, since non-drivers lose just as much money as drivers, due to the parking. Dividend Account Parking (DAP) is presented as a mitigation measure for any Climate Action Plan (CAP) or for any application where sustainability is a goal. The parking is shared, convenient, fully automated, and value priced with a congestion-pricing algorithm. Earnings go to those losing money because the parking is provided. Motivations are provided, based on an Air and Waste Management Association (AWMA) paper.
