Engineering, construction and environmental strategies for one of the most complex issues facing power generators today.
TRC is a trusted partner assisting current and former coal-fired power plant owners/operators to address the risks related to the management of fly ash, bottom ash and other coal combustion residuals (CCR). Our scientists and engineers are experts on the physical and chemical properties of CCR and CCR unit closures, including beneficial use. We understand the potential environmental impacts and design and implement mitigation solutions that support Federal, State and local regulatory compliance.
TRC’s integrated engineering and construction solutions are applied throughout the project lifecycle. We have subject matter experts in all aspects of the CCR rule, including evaluating/applying Federal and State regulations, identifying technical remedies and business implications for compliance options and designing engineering solutions to address site-specific issues.
Our clients receive added value through our ability to execute all necessary permitting, engineering and design with realistic constructability input and our ability to turn-key landfill and CCR pond closures or new construction. This can bring significant benefit from schedule reductions, helping to meet regulatory windows, and cost savings throughout the project execution.
Our solutions for coal ash management include:
TRC is your trusted partner, helping to navigate the economic, environmental and regulatory pressures as well as the rapid technological advancements impacting successful coal ash management. Learn more about our strategic consulting and integrated technical solutions that mitigate coal combustion residuals risk, reduce project costs and help you achieve your organizational goals.
The rules governing CCR management are complex. As Federal, State and Local regulatory requirements evolve, power generators face compliance pressure and risks. TRC is your trusted partner, helping you design and implement appropriate mitigation solutions.
EPA publishes final rule for CCR management under RCRA subtitle D. EPA finalizes Effluent Limitations Guidelines and Standards.
Congress passes the WIIN Act, giving EPA authority to implement a federal CCR permit program or approve state programs.
EPA signs “Skinny Rule” extending to Oct. 2020 mandatory closure of unlined surface impoundments that exceed applicable GWPS or that fail to meet location standards for aquifer separation.
DC Circuit Court strikes down parts of 2015 CCR Rule, including continued use of unlined ponds and exemption for legacy ponds.
DC Circuit Court upholds Oct. 2020 extension, without vacatur, until new rulemaking.
EPA Publishes Holistic Approach to Closure: Part A, requiring initiation of closure or retrofit of all unlined surface impoundments (including clay-lined) by April 11, 2021. Includes options to continue operating CCR and non-CCR waste streams in these impoundments via Alternative Closure requirements.
EPA Publishes Holistic Approach to Closure: Part B, allowing certain unlined surface impoundments to make liner equivalency demonstrations.

TRC’s extensive background in CCR compliance support under the current CCR rule helps our clients get in front of these new regulations.
New EPA Communications highlight new Coal Combustion Residual compliance expectations, a shift from the current program.
Many utilities are implementing corrective action at coal combustion residual (CCR) surface impoundments under Federal or State CCR Regulations, with implications for groundwater protection standards.
With the upcoming five-year periodic assessment and plan deadlines rapidly approaching for landfills and surface impoundments, power generators subject to the CCR Rule should also consider audits to ensure their facility records and external-facing web sites are complete and documents are up-to-date.
Regulatory requirements, plant retirements, changes to facility operational profiles, environmental liability management and political and social pressures are among the factors driving utilities to close or consider closing their coal ash ponds.
