Dayton Power & Light would like to add biomass as a fuel source to its Killen power plant in Adams County. The utility says that the renewable fuel will consist of briquetted wood, grass and other cellulosic biomass. DP&L would like for biomass to provide up to 5 percent of the total heat input of one of the plant's boilers. The plans are the subject of an Ohio EPA draft air permit, which can be read in its entirety here (pdf required). Ohio EPA will hold a public information session on the draft air permit at 6 p.m. on Monday, Dec. 13 at the Manchester Community Center, 400 Pike St. in Manchester. The agency is also accepting written comments on the draft permit until Dec. 20.
