(Name of Applicant Business Entity) Tc.wo Attachment A Dry Bottom Ash Handling System As a result of Coal Ash Management Act and the federal CCR Rule,Allen's bottom ash handling must be converted from a wet sluice operation to a dry ash handling system. This project will construct a closed loop wet sluice to dry bottom ash conversion system. It involves following: • Construction of two remote submerged flight conveyors(RSFCs). • Construction of return piping from RSFCs to the boiler. • Installation of mechanical and electrical equipment to support design of system conversion • Update of DCS control system to allow functional plant operations This project will procure and install RSFCs that will extract the bottom ash transported to the RSFC by way of the bottom ash sluicing system. Multiple RFSCs will be sized and installed in a cross configuration design to allow one RSFC to be taken off line for maintenance.This project will install the piping and control mechanisms to support cross configuration of the system.The bottom ash sluicing system will be modified into a closed loop system.A surge tank,and a maintenance tank will be procured and installed as part of this new closed loop bottom ash system.The return pumps and piping will be procured and installed into the new bottom ash system.This project will replace the existing high pressure service water booster pumps, and will tie into the bottom ash sluicing piping going to the existing ash ponds. Modifications will be made, by this project,to the existing system supplying water to the bottom ash sluicing system.This project will install a processing area to receive extracted dry bottom ash and allow for processing of the dry bottom ash into transporting vehicles.This project will construct all driving areas associated with the loading of the dry bottom ash into transport vehicles.This project will install new AC power equipment and modify the existing plant equipment necessary to support this project. Spare parts associated with this project will be supplied by this project.
