Coal Combustion Residuals
Monofill Expansion Master Planning, Design, Permitting and Construction Quality Assuranc
MidAmerican Energy Company (MEC) owns and operates the Louisa Generating Station in Iowa. As part of the implementation of the Coal Combustion Residue (CCR) rules, the station is being converted from a wet to a dry ash handling system. MEC’s goal is to build a “zero discharge” dry ash monofill, and to permit and construct a new ash monofill to be compliant with the Federal CCR rules. Foth’s innovative approaches to leachate management and our expertise in design and permitting landfills is providing MEC with a comprehensive solution to convert to dry ash disposal. Foth is also providing ash monofill design and master planning services.
Foth is leading the design efforts and implementing innovative ideas like a gravity leachate collection system and zero discharge leachate management. Foth installed a groundwater monitoring network to support the new monofill which required a hydrologic investigation and report, and the development of a hydrologic monitoring system plan. To facilitate successful permitting of a new monofill, Foth developed an updated Emergency Response and Remedial Action Plan, updated Development and Operations Plan, Fugitive Dust Control Plan, Storm Water Run-On Run-Off Plan, Closure Post-Closure Plan, and a Threatened and Endangered Species Survey Report.
Working collaboratively with the MEC team, Foth has enabled the client to maintain compliance with the Federal CCR rules and successfully continue operations.
