Duke looking to add 29 years to the Zimmer coal plant landfill

The Ohio Environmental Protection Agency has scheduled a Nov. 13 public meeting and hearing on a proposed expansion of Duke Energy’s (NYSE: DUK) Zimmer Residual Waste Landfill.

The landfill is located about 3.5 miles east of the coal-fired William H. Zimmer generating station. If approved, the disposal area would increase by 89 acres to a total of 283 acres. The approved disposal capacity would increase by 19.1 million cubic yards to 41.1 million cubic yards.

The new life expectancy of the landfill would be 29 years based on an average daily waste intake of 2,795 tons. The facility would take fly ash, bottom ash and gypsum generated at the Zimmer plant, the Ohio EPA noted in an Oct. 31 statement. Written comments must be received by the close of business on Nov. 22.

“The W. H. Zimmer Station is a nominal 1,300-megawatt facility with one coal/steam unit located in Moscow, Ohio, approximately 35 miles east of Cincinnati,” said the Duke website. “Duke Energy owns 46.5 percent of the unit (Dayton Power & Light owns 28.1 percent and American Electric Power owns 25.4 percent). Zimmer Station is located in the Reliability First region and is dispatched into PJM.”

Zimmer was a conversion of an uncompleted nuclear facility and it went online in 1991, making it a relatively new power plant when compared to the rest of the U.S. coal fleet.

U.S. Energy Information Administration data shows the plant this year taking coal from a variety of sources, including the Century and Powhatan No. 6 longwall mines in Ohio of Murray Energy, the Cumberland longwall mine in Pennsylvania of Alpha Natural Resources, and the River View room-and-pillar mine in western Kentucky of Alliance Resource Partners.
