CCR Impoundments Gredell Engineering is highly qualified to provide Coal Combustion Residual (CCR) services with a thorough understanding and proper interpretation of the federal and state regulations. Our CCR experience includes volumetric estimates, dewatering, clay liner evaluations, hazardous potential classification assessments, construction history, structural stability and safety factor assessments, and inflow design flood control system plans. Municipal Solid Waste (MSW) & CCR Landfills Gredell Engineering has built its practice in Missouri’s power generation industry and municipal solid waste (MSW) landfills around the strength of our staff’s collective understanding of environmental regulatory compliance and the geologic and engineering design and construction needs that are required for implementation.
