THIS 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
HF LEE 1982 BASIN. AS SUCH, A DAM DECOMMISSIONING PLAN WILL BE SUBMITTED AT A
LATER DATE PER DUKE ENERGY DIRECTION.
PROJECT DESCRIPTION:
THE INTENT OF THIS PROJECT IS TO COMPLETE THE CAMA CLOSURE PLAN FOR THE HF LEE
ENERGY COMPLEX 1982 BASIN (WAYNE-022).
BACKGROUND INFORMATION:
THE HF LEE ENERGY COMPLEX IS LOCATED ADJACENT TO THE NEUSE RIVER NEAR GOLDSBORO, NORTH
CAROLINA. IT IS REPORTED THAT THE 1982 BASIN WAS IN SERVICE FROM 1982 THROUGH OCTOBER 2012
WHEN THE THREE COAL-FIRED UNITS WERE RETIRED. CCR HAS HISTORICALLY BEEN DEPOSITED AT THE
HF LEE SITE BY HYDRAULIC SLUICING OPERATIONS FOR BOTH FLY ASH AND BOTTOM ASH MATERIAL.
THERE ARE NO LONGER ANY ASH DISPOSAL OPERATIONS ON GOING WITH THE PERMANENT
RETIREMENT OF THE FOSSIL GENERATING UNITS. ADDITIONALLY, NO OTHER MATERIALS, SUCH AS
OFFSITE STORMWATER, ARE DEPOSITED IN THE BASIN.
THE 1982 BASIN (WAYNE-022) IS LOCATED AT THE NORTHEAST CORNER OF THE SITE, JUST NORTH OF
THE HF LEE ENERGY COMPLEX COOLING POND (WAYNE-009). THE NEUSE RIVER RUNS BETWEEN THE
NORTH END OF THE HF LEE ENERGY COMPLEX COOLING POND AND THE SOUTH END OF THE 1982 BASIN
SEPARATING THE TWO BASINS.
WOOD ENVIRONMENT AND INFRASTRUCTURE SOLUTIONS IS RESPONSIBLE FOR DEVELOPMENT OF THE
HF LEE 1982 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 AT THE HF LEE
ENERGY COMPLEX IN WAYNE COUNTY, NC. CCR MATERIALS WILL BE HAULED TO AN ON -SITE ASH
RE -BURNER FOR BENEFICIAL REUSE.

THIS 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
HF LEE BASINS 1, 2 & 3. AS SUCH, A DAM DECOMMISSIONING PLAN WILL BE SUBMITTED AT A
LATER DATE PER DUKE ENERGY DIRECTION.
PROJECT DESCRIPTION:
THE INTENT OF THIS PROJECT IS TO COMPLETE THE CAMA CLOSURE PLAN FOR THE HF LEE
ENERGY COMPLEX BASINS 1, 2 & 3 (WAYNE-031, WAYNE-032, WAYNE-033).
BACKGROUND INFORMATION:
THE HF LEE ENERGY COMPLEX IS LOCATED ADJACENT TO THE NEUSE RIVER NEAR GOLDSBORO, NORTH
CAROLINA. IT IS REPORTED THAT BASINS 1&2 HAVE BEEN INACTIVE SINCE THE LATE 1960'S; AND BASIN 3
HAS BEEN INACTIVE SINCE 1973. CCR HAS HISTORICALLY BEEN DEPOSITED AT THE HF LEE SITE BY
HYDRAULIC SLUICING OPERATIONS FOR BOTH FLY ASH AND BOTTOM ASH MATERIAL. THERE ARE NO
LONGER ANY ASH DISPOSAL OPERATIONS ON GOING WITH THE PERMANENT RETIREMENT OF THE
FOSSIL GENERATING UNITS. ADDITIONALLY, NO OTHER MATERIALS, SUCH AS OFFSITE STORMWATER,
ARE DEPOSITED IN THE BASIN.
BASINS1&2 (WAYNE-031 & WAYNE-032) ARE LOCATED IN THE NORTHWEST CORNER OF THE SITE
ADJACENT TO THE NEUSE RIVER ON THE EAST SIDE AND ADJACENT TO A TRIBUTARY STREAM
(HALFMILE BRANCH) TO THE NEUSE RIVER ON THE SOUTH SIDE. BASIN 2 WAS CONSTRUCTED AS AN
ADDITION TO BASIN 1 ON THE EAST SIDE. THERE IS A COMMON DIKE SEPARATING THE TWO BASINS;
HOWEVER, BASIN 1 HAS NO OUTLET STRUCTURE AND THE TWO BASINS WORK AS A COMBINED BASIN.
BASIN 3 (WAYNE-033) IS LOCATED ON THE SOUTHWEST CORNER OF THE SITE ADJACENT TO THE NEUSE
RIVER ALONG THE EAST SIDE.
WOOD ENVIRONMENT AND INFRASTRUCTURE SOLUTIONS IS RESPONSIBLE FOR DEVELOPMENT OF THE
HF LEE INACTIVE ACTIVE ASH BASINS EXCAVATION PLAN, WHICH IS CURRENTLY AT 30% COMPLETE, AS
DUKE ENERGY PREVIOUSLY IDENTIFIED THIS SITE TO BE A PART OF THE BENEFICIAL REUSE PROGRAM
AT THE HF LEE ENERGY COMPLEX IN WAYNE COUNTY, NC. CCR MATERIALS WILL BE HAULED TO AN
ON -SITE ASH RE -BURNER FOR BENEFICIAL REUSE.
