Evaluating Ccr Unit Closure Options – Closure In Place Or Closure By Removal, Rick Buffalini
Evaluating Ccr Unit Closure Options – Closure In Place Or Closure By Removal, Rick Buffalini
World of Coal Ash Proceedings
Evaluating Surface Impoundments Closure by Removal and Closure in Place Options Authors Mr. Rick Buffalini - United States - Civil & Environmental Consultants, Inc. Abstract The USEPA interpretation of the 2015 CCR Regulations is that closure in place requires that the CCR not be in contact with groundwater, that post-closure infiltration of groundwater from the subsurface be eliminated, and that free liquids be eliminated from the CCR. As a result, owners of surface impoundments that had previously intended to close in place are now evaluating other options to dewater the CCR or closure by removal. This presentation will address evaluations …

Water Management And Construction Impacts, Christine Harris
World of Coal Ash Proceedings
Water Management and Construction Impacts Authors Mrs. Christine Harris - United States - Groundwater Treatment and Technology, LLC (GWTT) Abstract When closing an ash impoundment there are many steps in the process. Understanding the relationship between water management and civil construction is important. In most cases, before civil construction can begin, free liquids must be removed from the impoundment. Usually, the water removed must be treated before it can be discharged. The success (or failure) of these two activities can have an impact on the ability of the civil construction contractor to perform the work. The responsibility for dewatering is …

World of Coal Ash Proceedings
Nature-based Solutions for CCR Closure Authors Mr. John Watrous - United States - Stantec Mr. Josh Running - United States - Stantec Ms. Amanda Ludlow - United States - Stantec Abstract Employing nature-based solutions (NbS) in CCR Unit closure can substantially reduce construction costs while supporting water treatment and management goals and investing in natural capital improvements. Real-world scenarios of natural capital development opportunities that support attaining carbon, biodiversity, and other environmental, social, and governance (ESG) goals are presented. Closure-by-Removal (CbR) is extremely expensive when compared to Closure-in-Place (CiP). The costs for CbR can be 400-1000% of CiP costs, which …

Beneficially Using Bottom Ash As Landfill Protective Cover, Ryan Doyle
World of Coal Ash Proceedings
The Overall Process of Beneficially Using Bottom Ash as Landfill Protective Cover, an Engineer’s Perspective Authors Mr. Ryan Doyle - United States - AECOM Abstract Using bottom ash as protective cover along the base of a landfill is one way to beneficially use coal combustion residuals (CCR). The bottom ash serves as a filter to prevent finer particles (e.g. fly ash) from clogging the geocomposite liner which transports leachate to the sump of the landfill cell. Understanding the gradation of the bottom ash and the material properties of the geocomposite are imperative to finding the right combination for an effective …

Paper_Sustainable Construction With Ccps - An Update For Europe -, Fabrice Fayola, Joachim Feuerborn
World of Coal Ash Proceedings
In Europe, the developments towards carbon neutrality by 2050 with impacts on fossil-fired production but also for construction materials and construction are finding it’s way. For fossil-fired energy and heat production this results in increased production by renewables and respectively discontinuous replacement production by coal power plants, and by this in availability issues for Coal Combustion Products (CCPs). For most member states phase-out dates have been published and some countries already phased-out. Although known and used for decades, especially fly ash is subject of increasing interest for the production of carbon-reduced cement and concrete. The CCP production in coal-fired power …

How Sustainable Is Your Coal Ash Cover System, Marc Theisen
World of Coal Ash Proceedings
How Sustainable is Your Coal Ash Cover System? Authors Mr. Marc Theisen - United States - Profile Products LLC Abstract Robust cover designs are integral for successful coal ash closures to ensure regulatory compliance while minimizing construction, operational and maintenance costs. Moreover, owners, designers and other stakeholders must meet Environmental, Social and Governance (ESG) obligations. With these goals in mind, cover designs should include considerations for reducing greenhouse gas emissions and carbon footprints while offering environmental sustainability and resilience for the life of the project. A vexing issue facing coal ash site restoration is often the lack of available onsite …

Coal Ash Engineering: A Look Back At The Past And Peak Into The Future, Ramachandran Kulasingam
World of Coal Ash Proceedings
Coal ash engineering has come a long way after jolted by the slide in Kingston in 2008 to closures of some of the largest and complex ash basins in the country underway in 2024. Research studies, field investigations, analyses, designs, dewatering, excavations, additional ash slides, and more forensic evaluations have all taken place. Engineering work has covered closures in place, closures by removal, hybrid closures, and landfills. Lessons have been learned, some forgotten, and some relearned. The merits of active versus passive dewatering, role of engineering in evaluating ash excavation stability versus pursuing a means and methods contractor experience approach, …

An Options Analysis –Final Waste Management, Breanne Kahnk, Todd Martin
World of Coal Ash Proceedings
Final Waste Management Options Analysis Authors Ms. BreAnne Kahnk - United States - TRC Mr. Todd Martin - United States - TRC Abstract The recent trend of retiring coal-fired power plants in favor of gas-fired and renewable energy facilities has resulted in the need for a number of partially filled CCR landfills to be closed prematurely. In addition, forthcoming CCR rule changes designed to address legacy CCR material will be a driver for making additional closure decisions for many historical CCR landfills. The costs and labor burden associated with the long-term care of a prematurely closed or legacy CCR landfill …

Paper_A Study On The Applicability Of Dry Bottom Ash As A Fine Aggregate For Lightweight Aggregate Concrete, Sangchul Shin, Jinman Kim, Hoonsik Hong
World of Coal Ash Proceedings
While wet bottom ash has been used as a lightweight aggregate for a long time, Research on a dry bottom ash emitted from thermal power plants is insufficient. Dry bottom ash has the potential to be used as an excellent lightweight aggregate in the field of construction materials. This study was performed to verify the applicability of dry bottom ash as a fine aggregate in lightweight aggregate concrete. As a result of the study, it was found that the slump loss was not significant up to 75% of the dry bottom ash replacement rate, and the use of dry bottom …
