The U.S. Army Corps of Engineers office in Louisville, Ky., will be taking public comment until Sept. 10 on an application by East Kentucky Power Cooperative for a Section 404 Clean Water Act permit on a coal combustion by-product (CCB) landfill at the J.K. Smith power plant in Clark County, Ky.
“The landfill is proposed, as needed, to provide EKPC’s Dale Power Station, also located in Clark County approximately 28 miles to the west, with a long term CCB waste storage site,” said a Corps public notice. “Dale Station’s existing approved special waste landfill is expected to reach its operational capacity sometime between 2014 and 2016.”
Under the permit application, a 64.4-acre special waste landfill would be constructed at the J.K. Smith plant and CCBs from Dale would be hauled by truck to the new landfill. An additional 255.1 acres would be impacted through excavation, as needed to provide for landfill cover. EKPC proposes to impact 2,901 linear feet of five intermittent stream channels, 1,975 linear feet of six ephemeral stream channels and 1.319 acres of five wetlands.
Under the proposal, these waters would be filled with about 2,767 cubic yards of clean native soil (clay) and layers of geosynthetic and geomembrane liners to create the liner system. Once this liner system is in place, the landfill would be capable of storing about 3,834,579 cubic yards of CCBs. This proposed CCB landfill facility is considered a “special waste” (waste of high volume and low hazard) landfill and is regulated by the Kentucky Division of Waste Management (KDWM). EKPC applied to KDWM to construct the landfill in May.
EKPC, a generation and transmission electric cooperative located in Winchester, Ky., owns and operates coal-fired generation at Dale (196 MW), Cooper (341 MW) and Spurlock (1,346 MW). The first plant built by EKPC was William C. Dale, located on the Kentucky River in Clark County. All four units at Dale are pulverized coal-fired units. The first two units have a rated capacity of 23 MW each and began commercial operation in 1954. The third unit is capable of producing 75 MW and began operation in October 1957. The fourth unit is also rated at 75 MW and began operation in August 1960.
EKPC on June 8 issued a request for proposals on 300-MW of new power supply, with resulting offers to be compared with new environmental control project costs for both the coal-fired Cooper Unit 1 and Dale. The risk-adjusted findings of this work should be filed with the Kentucky Public Service Commission in early 2013.
