Staff answered all questions presented and provided access to all areas of the site where inspection was requested. Work in the coal ash areas continues. Excavation of both coal ash ponds and the LOLA area is complete. The "84" pond has been filled. Remaining waters in the "71" pond and the LOLA excavation remain idle as the facility evaluates the final dewatering procedure for these two areas. The excavatior landfill capping process is nearly complete. Stormwater basins for landfill stormwater outfalls 010 and 011 are in place. The on -site Evoqua treatment facility continues to treat and discharge landfill leachate, groundwaters and stormwaters at outfall 001. The treatment performance of this system appears to be excellent according to recently -submitted data. All measured parameters are well below permit limits. A review of effluent data submitted since the last site inspection (8/18) revealed no permi limit exceedances for the permitted outfalls.
