Solid Waste / Coal Combustion Residuals (CCR)

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. Since 2003, Gredell Engineering has worked with eight of Missouri’s coal-fired power plants on CCR-related projects involving primarily solids, process water and stormwater management. Solid Waste Processing Facilities Gredell Engineering provides solid waste processing and recycling services including preliminary planning, support for local permitting and providing the necessary plans, reports and supporting documents required to apply for and obtain a solid waste processing facility construction and operating permit for municipal solid waste transfer stations. Our services include assistance with obtaining a Missouri Department of Transportation (MoDOT) entrance permit, development of site grading plans for construction purposes and execution of a geotechnical engineering evaluations, including structural foundation design and specifications.
