WEATHERSPOON POWER PLANT 1979 ASH BASIN (ROBES-009). 0 5 A 7 FIGURE 2 REV. F BACKGROUND INFORMATION: THE W.H. WEATHERSPOON STEAM ELECTRIC PLANT IS LOCATED NEAR THE LUMBER RIVER IN LUMBERTON, NORTH CAROLINA. THE WEATHERSPOON PLANT IS REPORTED TO HAVE BEGUN COMMERCIAL OPERATION IN THE EARLY 1950S. IN FEBRUARY 2012, THE THREE COAL-FIRED UNITS WERE RETIRED. ASH MATERIAL OR COAL COMBUSTION RESIDUAL (CCR) HAS HISTORICALLY BEEN DEPOSITED WITHIN THE ASH POND LOCATED ON THE PLANT SITE BY HYDRAULIC SLUICING OPERATIONS FOR BOTH FLY ASH AND BOTTOM ASH MATERIAL. THERE ARE NO LONGER ANY ASH DISPOSAL OPERATIONS WITHIN THE ASH POND AREAS WITH THE PERMANENT RETIREMENT OF THE FOSSIL GENERATING UNITS. THE 1979 ASH BASIN (ROBES-009) IS LOCATED EAST OF THE PLANT SITE WHICH IS ADJACENT TO THE LUMBER RIVER. WOOD ENVIRONMENTAL AND INFRASTRUCTURE SOLUTIONS IS RESPONSIBLE FOR DEVELOPMENT OF THE WEATHERSPOON 1979 ASH BASIN EXCAVATION PLAN, WHICH IS CURRENTLY AT 100% COMPLETE, AS DUKE ENERGY PREVIOUSLY IDENTIFIED THIS SITE TO BE A PART OF THE BENEFICIAL REUSE PROGRAM. CCR MATERIALS WILL BE HAULED TO A RE -ASH BURNER FOR BENEFICIAL USE. PROJECT NOTES: THE EXISTING CAMA CLOSURE PLAN THAT IS PRESENTED HEREIN IS CURRENTLY STILL IN DEVELOPMENT AND SHOULD BE USED TO GENERALLY DEPICT THE FINAL PROPOSED CONDITION OF THE WEATHERSPOON 1979 ASH BASIN. AS SUCH, A DAM DECOMMISSIONING PLAN WILL BE SUBMITTED AT A LATER DATE PER DUKE ENERGY DIRECTION. REFERENCES: 1. TOPOGRAPHY OF ASH BASIN FROM MCKIM & CREED SURVEY DATED JANUARY 18, 2018. 2.
