The Coal Ash Management Act (CAMA) of 2014 and the Mountain Energy Act of 2015 require the excavation of ash basins at the Asheville Steam Electric Plant (Plant). Duke Energy has recently completed excavation of the 44‐acre 1982 ash basin in order to comply with these regulations. Visual verification of ash removal by Amec Foster Wheeler was conducted in accordance with the Coal Combustion Residuals Removal Verification Procedure Rev. 0 dated June 9, 2016. FIELD METHODOLOGY Once ash removal was verified, SynTerra collected soil samples from the 1982 basin. Samples were analyzed for fly ash percent composition using Polarized Light Microscopy (PLM). PLM analysis involves the use of a polarized light microscope to analyze the soil samples under plane and polarized light to identify fly ash particulate matter in a high‐resolute manner. Sample locations and intervals sampled, along with associated PLM results, are presented in Table 1 and displayed on Figures 1 and 2. Soil sampling was conducted in accordance with the Duke Energy’s Standard Operating Procedure for Soil Sampling for Ash Basin Excavation North Carolina Ash Basin Closure Rev. 0 dated September 2016 (Attachment 1). Soil samples were collected from grid point locations from the Amec Foster Wheeler 100‐foot grid system overlaid on the 1982 ash basin footprint. These locations are identified on Figure 1. Sampling points were selected to provide adequate spatial distribution throughout the ash basin and surveyed and staked by Amec Foster Wheeler via GPS rover. Sample density was based on a 1 sample per acre ratio; however, where appropriate, additional locations were sampled to provide more complete coverage of the basin (total of 55 sample locations). A surface sample (0‐6 inches below ground surface (bgs)) was collected at all locations; collection of a deeper sample (2.5 feet‐3.0 feet bgs) was attempted at all locations. Where auger refusal prevented collection of the deeper sample, an intermediate 1982 Ash Basin Closure PLM Results Summary September 28, 2016 Asheville Steam Electric Plant Page 2 P:\Duke Energy Progress.1026\02.ASHEVILLE PLANT\40. 1982 Basin Closure Soil Sampling\Basin Closure Soil Sampling Report\FINAL\Soil Sampling Memo_FINAL.docx sample was collected below 6 inches bgs and above 3.0 feet bgs. At many locations auger refusal was encountered within 6 inches of the surface, thus no deeper interval was collected. Duplicate samples were collected at three locations (approximately 1 duplicate per 20 samples). Soils were collected with a decontaminated tool (spade or auger) from appropriate intervals and placed in a decontaminated, homogenization bowl. The sample was then homogenized and placed in 8‐ounce glass amber jars and tightly secured with provided lid. Samples were submitted to Duke Lab in coolers containing wet ice at the end of each sampling day, with corresponding chain‐of‐custody signed and sealed. RESULTS AND DISCUSSION PLM lab reports are included in Attachment 2. Sample grid points with corresponding PLM results are displayed on Figure 2. All samples returned PLM results less than 50% composition of fly ash, except for the initial sample of node J‐11 which produced a PLM result of 50% fly ash. Based on this result, Duke Energy directed excavation of a 50’ radius surrounding the J‐11 location with Duke Energy and Amec Foster Wheeler oversight. SynTerra collected a verification sample at node J‐11 which returned a PLM result of 3% fly ash.

Revision 0 Page 1 1.0 PURPOSE The purpose of this Standard Operation Procedure (SOP) is to provide a standardized method for collecting soil samples at Duke Energy North Carolina ash basins that are to be closed via excavation. Soil samples are being collected following all visible ash removal from existing basins to support closure activities. This SOP is applicable to the collection of representative soil samples. Analysis of soil samples may be chemical or physical in nature and may be used to determine the following:  Extent and magnitude of constituent occurrence  Input concentrations for groundwater fate and transport model The methodologies discussed in this SOP are applicable to the sampling of soil in ash basin excavation areas. For the purposes of this procedure, soils are those mineral and organic materials remaining after all visible ash has been excavated. 2.0 SOIL SAMPLING SOP 2.1 Method Summary This SOP has been adapted from EPA SOP #2012 and #2006. Surface soil samples are collected directly using stainless steel or plastic trowel, spade, shovel, or scoops. Following collection, soil is transferred from the sampling device to a stainless steel or plastic bowl to be homogenized. Once homogenized, the soil is transferred into Duke Energy Laboratory supplied sample bottles. Soil samples will be submitted for the following analyses: total metals and SPLP metals. Analytical methods for total metals and SPLP metals are described in Table 1. Ash presence is quantitatively determined by polarized light microscopy (PLM) by RJ Lee Laboratory. PLM analysis passes visible light through a pair of polarizing filters to create optical effects used in identifying unknown materials. This method is commonly used in asbestos and coal ash identification. 2.1.1 Equipment  Stainless steel or plastic trowel, scoop, spade or shovel – used for collecting soil samples from surface locations.  Sample containers – To be supplied by Duke Energy Laboratory with appropriate cooler(s). Estimated that 5-8 ounce samples bottles with Teflon-lined lids will be required for each sample location and sample depth. For return of cooler to the lab, ice will be required.  Gloves – used for personal protection and to prevent cross-contamination of samples – nitrile, disposable, powderless. SOP for Soil Sampling September 2016 Duke Energy Carolinas, LLC & Duke Energy Progress, LLC. Revision 0 Page 2  Field clothing and Personal Protective Equipment – used as specified in the site Health and Safety Plan.  Sampling flags – used for identifying soil sampling locations.  Field notebook – a bound book used to record progress of sampling effort and record any problems and field observations during sampling.  Three-ring binder book – used to store necessary forms and record and track samples collected at the site.  Permanent marking pen – used to label sample containers, document field logbooks and data sheets.  Stainless steel or plastic spoon – used for homogenizing soil samples within a stainless steel or plastic bowl.  Stainless steel or plastic bowl – used for homogenizing soil samples, when applicable.  Camera – used for photo-documentation of sample locations and samples.  GPS – device used to obtain elevation, latitude and longitude of sample location.  Trash bag – used to dispose of gloves and any other non-hazardous waste generated during sampling.  Decontamination supplies and equipment. 2.1.2 Sample Locations General locations for soil sampling are determined by the soil scientist in the field at a rate of one soil sample for every 1 acre of ash basin area excavated. Actual sampling locations on site may vary to account for site conditions and to allow collection of representative samples. Representative samples reflect areas where all ash has been visually excavated and natural soil is observed. 2.1.3 Collection of Representative Samples For the purpose of this method, surface soil is considered to range from 0 to 6 inches in depth while a deeper sample is considered to range from 2.5 to 3 feet below ground surface (or refusal, if encountered). A surface soil sample and deeper sample will be collected at each location for every 1 acre of ash basin excavated. A new pair of nitrile gloves is worn at each sampling location and each depth. Each sampling location is recorded on the site map prior to collecting the sample if location is not already noted on the map. The GPS location of each sampling location (i.e. elevation, latitude and longitude), sample descriptions, and area photographs are also recorded. All sampling equipment is decontaminated prior to use irrespective of depth. The following procedure will be used to collect representative soil samples with a scoop, shovel, or trowel: SOP for Soil Sampling September 2016 Duke Energy Carolinas, LLC & Duke Energy Progress, LLC. Revision 0 Page 3  Locate general sampling locations.  Determine suitability of sampling location for a representative sample.  If sampling location appears to reflect representative conditions that would allow collection of a representative sample, proceed with sampling procedure. If location is not indicative of conditions that would allow collection of a representative sample, notify the project manager so an alternate location can be identified.  Using a decontaminated sampling instrument, remove the desired thickness and volume of soil from the sampling area. Will require enough soil to fill five 8- ounce sample bottles.  Transfer the sample into an appropriate sample or homogenization bowl. Non- dedicated containers should be adequately decontaminated. Stir for approximately one minute until there appears to be a uniform color and consistency.  Transfer homogenized sample to a labeled container(s) of appropriate size and construction for the analyses requested.  Secure sample container tightly. 2.1.4 Sample Preservation, Containers, Handling and Storage Chemical preservation of soils is generally not recommended. Cooling to 4oC on wet ice is usually the best approach, supplemented by the appropriate holding time for the analyses requested. The Duke Energy Laboratory will supply the appropriate sample bottles for the collected soil samples. The sample volume is a function of the analytical requirements and the Duke Energy Laboratory will ensure the appropriate number of bottles are supplied. Table 1 contains a list of parameters to be analyzed with corresponding reporting units and analytical methods. If a parameter or group of parameters is not included in Table 1, the laboratory performing the analysis should be contacted to determine the appropriate sample bottles, volumes, and preservatives. All non-dedicated sampling devices should be decontaminated and wrapped in plastic. The sampling device should remain in this wrapping until it is needed. Each sampling device should be used for only one sample and then decontaminated or disposed of. Non dedicated sampling devices should be cleaned in the field using the decontamination procedure described below. 2.1.5 Decontamination Decontamination procedures can be time consuming; having a sufficient quantity of sampling tools available is recommended. All non-dedicated sampling equipment must be decontaminated prior to reuse. Equipment decontamination consists of: SOP for Soil Sampling September 2016 Duke Energy Carolinas, LLC & Duke Energy Progress, LLC. Revision 0 Page 4 1. Detergent wash and brush cleaning 2.

Based on ourobservationsconducted in accordance with the Coal Combustion Residuals (CCR)RemovalVerification Procedure Rev. 0 dated June 9, 2016 and attached as “Attachment 1” (Procedure),we conclude visible ash has been removed as documented in this letter. Background The 1982 Ash Basin is located near Arden,North Carolina as shown in Figure 1. The basin wasconstructed in 1982 and received ash until approximately 2015.The basin area isapproximately43.9 acres and the basin volume was estimated at 3.1 million cubic yards.Since2006,Duke Energy has been removing and transporting ash to off-site structural fills forbeneficial use, permitted landfills, and the temporary ash storage unit within the 1964 ash basin. Amec Foster Wheeler and Duke Energy developed the Procedure to prescribe specificcontractor and engineering tasks needed to evaluate Visual CCR removal.It includesdevelopinga pre-construction topographic base map to determine the estimated base of ash(Figure 2). Amec Foster Wheeler construction quality assurance (CQA) personnel and Engineer conductedthefield visual assessment.A 100 foot grid (Figure 3)was established with vertical andhorizontal control and the base of excavation was compared to the estimated base of ash.AmecFoster Wheeler personnel then observed the surface represented by the grid point anddeterminedif visible ash was present. If present, the location was documented,ash wasremoved by the contractor and the location was re-assessed.When visible ash was not present,the CQA personnel hand-augered, dug, or mechanically excavated at the grid point (±15 feet) to CCR Removal Verification Asheville Steam Electric Generating Plant 1982 Ash Basin Amec Foster Wheeler Project No.: 7810160620 Sample Location Date Performed Elevation from GPS (ft.)Visual Classification Color Fill/Residuum Primary Source Removed?

CCR’s for this protocol are understood to be fly ash or bottom ash. Closure by Removal is defined herein as removing the primary source (primary source of potential constituents of interest) to the point CCRs are not visible to the unaided eye at the ground surface. Primary Source ash is the main body of ash that was deposited in the basin or fill. This method is intended solely to verify and document primary source ash removal and is not intended to validate environmental quality standards of the subsurface (considered the secondary source of potential constituents of interest). Following this method will yield results indicating that the primary source has been removed as verified by visual observation methods described herein. Prior to or During Ash Removal by Contractor 1.Engineer will review topographic mapping, aerial photography, and boring logs toestimate the pre placement topography and/or CCR/soil interface.2.Engineer will prepare a CCR unit map illustrating a grid spacing of 100 feet. Each gridpoint will be assigned a unique identifier. Each node of the grid spacing (grid point) willrepresent a verification location.3.Project will excavate ash until a visible change in color or texture, confirmsremoval. This location shall be referred to as the CCR/soil interface. If visual evaluationis inconclusive then request additional evaluation to confirm ash removal.4.Engineer will evaluate the excavated surface elevation relative to the pre placementtopography and/or CCR/soil interface. Periodically check bottom elevation to evaluate iffill may be present above historic bottom elevations. If evaluation indicates fill is presentthen follow Fill Evaluation Criteria defined herein. Memo Date: June 9, 2016 To: Phillip Banks, Mike Clough, Henry Duperier, Chris Ussery - Duke Energy From: Ken Daly, Ken Hardin, Luke Williams - Amec Foster Wheeler CC: NA Ref: CCR Removal Verification Procedure Re: Asheville Ash Basin Closure Project CCR Removal Verification Procedure June 9, 2016 Asheville Ash Basin Closure Project Amec Foster Wheeler Project No.: 7810150250 2 Ash Removal Verification Protocol CQA personnel are defined as a representative of the Engineer and may be a geotechnical engineer, geologist, or engineering technician. 1.CQA personnel will locate each grid point by GPS or survey control, determine theelevation, and evaluate whether that point is above or below the historic bottomelevations.2.CQA personnel will then observe the surface area represented by the grid point to note ifvisible ash is present at the surface. If present, the location should be documented andis to be removed by the contractor. If evaluation indicates the surface soils are notresiduum or bedrock (as determined by the areal context, elevation, or relic structure),then they will hand-auger, dig, or mechanically excavate at the grid point (±15 feet) to adepth of 2 feet (or refusal) below the surface and perform a visual-manual classificationof the soils according to ASTM method D2488. Conditions shall be documented bytaking photographs.3.The classification indicator for fly ash will be grey to black silt-size particles with noplasticity. The classification indicator for bottom ash will be grey to black sand to gravelsized particles and porous. If the material cannot be positively identified as soil, it maybe removed or a sample may be evaluated by microscope. The Engineer shall reviewthe specific conditions with Duke Energy stakeholders and gain consensus beforeproceeding with microscope evaluation. If microscope results indicate the predominantparticle shape is spherical (for fly ash) and particle size is consistent with known fly ashor bottom ash particle sizes, then the material will be confirmed to be ash.4.If the grid point elevation is near the historic bottom elevation and either (1) residuum isindicated by observation, or (2) soil is confirmed by visual manual classification (ASTMD2488), CQA personnel may conclude the primary source is removed. Fill Evaluation Criteria Fill areas within the basin should be identified prior to visual ash removal during Ash Removal by Contractor. They are not anticipated to be performed during the above Ash Removal Verification Protocol. The following procedures provide an approach that can be used to ascertain if the fill can remain in place. The procedures specified are based on the fill material depth. 1.If the elevations are less than eight feet above historic bottom elevations and residuumis not observed, then test pits may be excavated to historic bottom elevations or untilresiduum or bedrock is encountered but no more than eight feet below the surface.a.The Engineer will evaluate existing information to determine if test pits arenecessary. If necessary he may recommend excavating test pits at a frequencyno tighter than 100 feet by 100 feet.b.If visible ash is not discovered based on procedures defined above, then theprimary source removal may be confirmed.c.If visible ash is discovered, then continue excavation to remove ash.2.If the elevation is more than eight feet above historic bottom elevations and residuum isnot observed, then refer to the Engineer. CCR Removal Verification Procedure June 9, 2016 Asheville Ash Basin Closure Project Amec Foster Wheeler Project No.: 7810150250 3 a.The Engineer will confirm historic information and recommend a drilling andsampling program at frequency no tighter than 100 feet by 100 feet to evaluatethe presence of ash below the fill in accordance with procedures defined above.If unusual features are revealed by the drilling, engineer mayrequest/recommend additional borings. Exploration is to be performed bycontinuous sampling during drilling.b.If visible ash is not discovered, then the primary source removal may beconfirmed.c.If visible ash is discovered, then continue excavation to remove ash.
