CCR Remediation & Coal Ash Pond Closure
End-to-end CCR remediation and coal ash pond closure services. From dewatering and treatment to regulatory compliance and closure execution, UCC Environmental delivers proven, site-specific solutions that minimize risk and ensure EPA CCR Rule compliance.
Protecting Groundwater and Meeting EPA CCR Rule Requirements
Coal Combustion Residual (CCR) remediation—commonly known as coal ash pond closure, is essential to protecting groundwater, reducing environmental liability, and meeting EPA and state regulations. UCC Environmental provides complete, integrated CCR solutions for utilities and industrial plants, including dewatering, treatment, closure design, and long-term monitoring.
Our approach blends regulatory expertise, advanced treatment technology, and field execution under one roof, ensuring schedule-critical closures are completed safely, efficiently, and in full compliance.
Comprehensive Coal Ash Dewatering and Ash Pond Closure Services
Every site presents unique challenges when it comes to wastewater management. With over a century of CCR expertise, UCC Environmental ensures that all critical factors—flow rate, CCR composition, particle size distribution, pH levels, and heavy metal contaminants—are carefully evaluated to develop solutions tailored to your facility’s needs.
Regulatory-Aligned Closure Strategies
We develop closure plans that align with CCR Rule and state requirements while minimizing cost and long-term risk. Our engineers focus on technically sound, executable designs that achieve compliance and provide lasting performance.
Solids Handling & Dewatering
Our high-capacity dewatering systems manage ash, slurry, and residual solids through wet conditioning, mechanical dewatering, and transport solutions. With over 105 years refining abrasion-resistant systems, we deliver equipment and designs proven to perform in demanding industrial environments.
Advanced Water Treatment & Reuse
Our engineered water treatment systems integrate clarification, ultrafiltration, nanofiltration, reverse osmosis, and advanced metals removal for compliance with stringent discharge limits. When required, we deploy Zero Liquid Discharge (ZLD) systems and water reuse strategies—customized for site-specific chemistries and supported by performance guarantees.
Integrated Engineering, Construction & Field Services
From pond stabilization and selective ash removal to system installation and commissioning, our integrated delivery model streamlines execution. We coordinate engineering, construction, and field service activities to improve quality control, reduce delays, and lower total project risk.
Operational Support & Staffing
We provide skilled operators, maintenance technicians, and field personnel to ensure smooth operation of treatment and dewatering systems. Our staffing and training programs minimize downtime and empower plant teams with on-site expertise.
Project Management Excellence
Our project management team oversees every phase—from initial planning and design through execution and closeout. With end-to-end control of scheduling, coordination, and budget, we deliver predictable results and on-time project completion.
Technology-Agnostic Flexibility
We select and integrate the best technologies from across the industry—unrestricted by OEM limitations. This ensures that each closure solution is optimized for performance, compliance, and lifecycle cost.
Closure Execution & Long-Term Support
Whether closure by removal, in-place capping, or hybrid approaches, we provide turnkey execution aligned with long-term performance goals. Our team supports dewatering, extraction, and flushing systems for ongoing stability and regulatory confidence.
