Coal Combustion Residuals (CCR)

HELPING CLIENTS MAINTAIN REGULATORY COMPLIANCE

GSI helps clients navigate through evolving regulatory landscapes by integrating technical services with project objectives, schedule constraints, and regulatory requirements.

GSI staff are recognized leaders in environmental engineering, hydrogeology, risk management, and environmental compliance, with decades of experience providing top-quality consulting services on regulatory and permitting projects. Clients rely on us to understand nuances in technical and regulatory matters and identify and address environmental concerns associated with management of CCR sites. Our multi-disciplinary team provides insight into the risks and costs associated with these properties to help our clients strategically address compliance, monitoring, and cleanup needs, and to establish long-term management strategies.

FEATURED PROJECTS

Groundwater Monitoring and Remediation

Texas

GSI is actively conducting semiannual groundwater detection and corrective action monitoring, as well as implementing groundwater remedies, at a Texas CCR site. This work also includes compliance reviews to ensure that Federal and new State of Texas requirements are met.

Third-Party Technical and Regulatory Review

Texas

GSI provided regulatory and technical review of a groundwater monitoring network developed for a CCR landfill at a different site in Texas. The review included statistical evaluations and recommendations for alternate sampling approaches to improve data quality and reliability, and to reduce false exceedances of regulatory threshold criteria.

Solidification of Coal Combustion Residue Sediment

Chemical Manufacturing Facility, Ohio

GSI conducted sampling and bench-scale studies to evaluate closure options for three CCR settlement ponds. The closure was completed by solidifying CCR sediment in-place and installing an engineered cover to prevent exposure to the CCR sediment and affected soils.
