BOUNDARIES WERE OBTAINED FROM AMEC FOSTER WHEELER ENVIRONMENTAL &
INFRASTRUCTURE, INC., NATURAL RESOURCES TECHNICAL REPORT (NRTR) FOR MAYO STEAM
ELECTRIC PLANT DATED JANUARY 20, 2014.
PROPERTY BOUNDARY PROVIDED BY DUKE ON APRIL 09, 2020.
ANTICIPATED BOTTOM OF ASH EXCAVATION GRADES PROVIDED BY AECOM.
EXISTING STORMWATER CULVERT SURVEYED BY ESP DATED MAY 26, 2020.
ASH BASIN BOUNDARY PRESENTED IN THIS DRAWING WAS PREPARED BY SYNTERRA FOR DUKE
NERGY. ACTUAL ASH BASIN BOUNDARY MAY VARY
EXISTING TOPOGRAPHIC INFORMATION WITHIN "2020 SURVEY LIMIT" WAS PROVIDED BY GPI ON
JULY 20, 2020.
ADJUSTED ESTIMATED SEASONAL HIGH GROUNDWATER ELEVATIONS DEPICTED REPRESENT
THE CONTOURS PROVIDED IN THE SYNTERRA TECHNICAL MEMORANDUM "LONG-TERM
SEASONAL HIGH GROUNDWATER ELEVATION ESTIMATION" DATED SEPTEMBER 9, 2020. THE
SEASONAL HIGH GROUNDWATER IS BASED ON BOTH MODELED AND ACTUAL DATA. CONSTANT
INPUT PARAMETERS WERE USED TO CREATE STEADY STATE FLOW CONDITIONS FOR THE SITE
AND BOUNDARY AREAS. THE CONSERVATIVE ADDITION OF THE FACTOR OF SAFETY (FOS) MAY
IN LOCALIZED INSTANCES PROJECT WATER LEVELS ABOVE GROUND SURFACE WHERE ACTUAL
FIELD DATA DOES NOT SUPPORT THIS CONDITION.
NOTES:
1. THE CONFIGURATION SHOWN ON THIS DRAWING WILL NOT EXIST AT A SINGLE POINT IN TIME.
THE PURPOSE OF THIS DRAWING IS TO SHOW COMPACTED SOIL LINER (CSL) SUBGRADE FOR
THE ENTIRE LANDFILL.
2. ALL BOUNDARIES ARE APPROXIMATE.
BASIS OF BEARINGS: NC GRID NAD83/2001, ELEVATIONS ARE BASED ON NAVD88.
4. FIELD CONDITIONS ENCOUNTERED DURING CONSTRUCTION MAY REQUIRE THE INSTALLATION
OF AN UNDERDRAIN. DESIGN OF THE UNDERDRAIN, IF NEEDED, WILL BE SUBMITTED TO
NCDEQ-SWS FOR APPROVAL PRIOR TO CONSTRUCTION OF THE UNDERDRAIN. A CONCEPTUAL
UNDERDRAIN DETAIL IS PROVIDED ON DRAWING .101, DETAIL 4.
BEDROCK CONTOUR DEVELOPMENT IS DEFINED IN THE GEOLOGICAL AND HYDROGEOLOGICAL
P T.
.-
6. THE CONTRACTOR SHALL ENSURE COMPLIANCE WITH THE EXCAVATION SOIL SAMPLING PLAN
FOR CONFIRMATION OF CCR REMOVAL.
7. EMERGENCY SPILLWAY TO BE DESIGNED UPON COMPLETION OF ASH BASIN CLOSURE DESIGN

GEOMEMBRANE SUBGRADE FOR THE ENTIRE LANDFILL.
ALL BOUNDARIES ARE APPROXIMATE.

THREE LEACHATE ACCESS PORTS WILL BE LOCATED DURING CONSTRUCTION TO
ALLOW DISCRETE SAMPLES FROM THE LANDFILL SUMPS (PHASE 1 AND PHASE 2)
AND ONE CONSOLIDATED SAMPLE UPGRADIENT OF THE LEACHATE BASIN.
CHIMNEY DRAIN LOCATIONS SHOWN ON THIS DRAWING ARE APPROXIMATE AND
MAY BE RELOCATED TO SUPPORT OPERATIONS AT OWNER'S DISCRETION.
6. THE CONTRACTOR SHALL ENSURE COMPLIANCE WITH THE EXCAVATION SOIL
SAMPLING PLAN FOR CONFIRMATION OF CCR REMOVAL.

2. EXISTING WETLAND DELINEATION SURVEY PROVIDED BY MCKIM AND
CREED DATED JUNE 18, 2018. THE WATERS OF THE US DELINEATION HAS
NOT BEEN APPROVED BY THE US ARMY CORPS OF ENGINEERS AT THE
TIME OF THE MAP CREATION. THIS MAP IS A PRELIMINARY
JURISDICTIONAL DETERMINATION ONLY. THE PRELIMINARY WETLANDS

SYNTERRA FOR DUKE ENERGY. ACTUAL ASH BASIN BOUNDARY EXTENT
A VARY.
7. ADJUSTED ESTIMATED SEASONAL GROUNDWATER ELEVATIONS
DEPICTED REPRESENT THE CONTOURS PROVIDED IN THE SYNTERRA
TECHNICAL MEMORANDUM "LONG-TERM SEASONAL HIGH
GROUNDWATER ELEVATION ESTIMATION" DATED SEPTEMBER 9, 2020.
THE SEASONAL HIGH GROUNDWATER IS BASED ON BOTH MODELED AND
ACTUAL DATA. CONSTANT INPUT PARAMETERS WERE USED TO CREATE
STEADY STATE FLOW CONDITIONS FOR THE SITE AND BOUNDARY
AREAS. THE CONSERVATIVE ADDITION OF THE FACTOR OF SAFETY (FOS)
MAY IN LOCALIZED INSTANCES PROJECT WATER LEVELS ABOVE GROUND
SURFACE WHERE ACTUAL FIELD DATA DOES NOT SUPPORT THIS
CONDITION.
8. LOCATION OF EXISTING UTILITIES IN THE VICINITY OF THE PROPOSED
LANDFILL LEACHATE FORCE MAIN TIE-IN TO THE EXISTING LINED
RETENTION BASIN WAS DIGITIZED BASED ON THE DRAWING "WATER
REDIRECTION PROGRAM WATER REDIRECTS ELECTRICAL DUCT BANK
PLANS". THE CONTRACTOR SHALL VERIFY THE LOCATION AND DEPTH OF
ANY EXISTING UTILITIES PRIOR TO FORCE MAIN CONSTRUCTION.
NOTES:
1. ALL BOUNDARIES ARE APPROXIMATE.
2. BASIS OF BEARINGS: NC GRID NAD83/2001, ELEVATIONS ARE BASED ON
