- CCR Containment
We provided professional services including detailed design, project management and coordination activities, as well as construction support, for a containment system at the Merom Generating Station to comply with the Coal Combustion Residual (CCR) Rule. The project was a result of the publication of the federal CCR Rule under the Resource Conservation and Recovery Act (RCRA), Subtitle D, which regulates storage and disposal of CCR materials generated at coal-fired power units. Hoosier Energy requested that our team design measures to containerize their existing CCR pile through the use of concrete containment and wind screens.
- Detailed design
- Project management
- Construction support
Our team first worked with Hoosier Energy to determine if the existing containment area conditions were applicable in meeting the CCR Rule’s definition of containment. Upon determining that the necessary conditions were not met, we proceeded with providing detailed design drawing and specification packages to concrete line the CCR containment area. We also provided general project oversight and coordination, aided in the selection of a qualified construction contractor and provided construction phase support services.
The detailed design package included concrete slab plans, sections and details including slab dimensions, curb and wall details, wind barrier procurement and design specifications, concrete jointing plans, and concrete pavement mix design requirements. Our team also provided an updated site arrangement with overall grading plans to control stormwater run-on and run-off.
FeaturesThe designed solution captured the following:
- Curbs and walls for purposes of containment and to minimize stormwater run-on into the containment area
- Sized to hold adequate amounts of CCR material, taking into consideration future needs
- Stormwater run-off flows were routed to a separate containment area
- Wind barriers designed to control wind erosion
