Dear Ms. Moutos:
525 S. Tryon St.
Charlotte NC, 28202
In accordance with the Environmental Control Monitoring Plan (ECMP) Revision 2, Duke Energy is providing
the results of semi-annual leachate and construction drain sampling and leak detection system (LDS)
monitoring results for the Allen Steam Station North Starter Landfill (NSLF), located near Belmont, in Gaston
County, North Carolina.
On March 4, 2024, leachate samples were collected from the NSLF and the leachate basin. The NSLF
construction drain sample was collected later, on March 27, 2024, after some access improvements were
made to the discharge location. The samples were collected by Duke Energy personnel and analyzed by the
Duke Energy Analytical Laboratory. A summary of sampling results can be found in the attached Report
along with the LDS monitoring results. The parameters tested are not bound by state groundwater or surface
water standards. The leachate is currently conveyed to the Station's lined retention basin (LRB), which
discharges via a NPDES wastewater permitted outfall. All laboratory analytical and field results are provided
in the appendices of the Report.
Allen Steam Station's NSLF is sampled semi-annually during March and September. The next landfill
sampling event is scheduled for September 2024 with documentation to follow.
If you need additional information regarding this submittal do not hesitate to email or call me at

Environmental Controls Monitoring Semiannual Report December 2023 through March 2024
North Starter Landfill 3619-INDUS
1.0 Background
This Environmental Controls Monitoring Semiannual Report is for the North Starter Landfill (NSLF or
landfill; 3619-INDUS) located at the Duke Energy Carolinas, LLC (Duke Energy) Allen Steam Station
(Allen, Plant, or Site). Monitoring results in this report are for the period of December 2023 through
March 2024.
The Environmental Controls Monitoring Plan (ECMP) establishes locations and procedures for
monitoring early detection of solid waste or leachate potentially released to the environment from the
NSLF. The Environmental Control Monitoring Plan, Revision 2 Update (ECMP, Revision 2 Update;
SynTerra, 2023) was submitted to the North Carolina Department of Environmental Quality (NCDEQ)
Division of Waste Management (DWM) on July 19, 2023, and was approved by the DWM on July 26,
2023. The March 2024 sampling event and this report comply with the ECMP, Revision 2 Update
(SynTerra, 2023).
The landfill is designed and constructed in accordance with North Carolina General Statute (NCGS)
130A § 295.4 for Combustion Products Landfills. This report is intended to satisfy the water quality
monitoring plan required by North Carolina Administrative Code Title 15A Subchapter 13B (NCAC 15A
13B) .0504(c)(8)(D) in accordance with NCGS 130A § 295.4(c).
1.1 Site Description
Additional Site description information can be found in Section 1.1 of the ECMP, Revision 2
Update (SynTerra, 2023).
1.1.1 Landfill
The approximately 25-acre landfill is located partially within the western portion of the
Retired Ash Basin [RAB] (Drawing 1). The NSLF is bound by Plant Allen Road to the
north, the RAB to the south and east (specifically the Distribution of Residual Solids
[DORS] Fills to the east), and upland areas to the west (Drawing 2).
The engineered base liner system of the landfill is designed and constructed with a
leachate collection and removal system above the primary liner and a leak detection
system (LDS) to monitor performance of the primary liner to prevent a release to the
environment.
The majority of waste intended for placement throughout the life of the landfill consists of
coal combustion residuals (CCR), predominantly fly ash and bottom ash. The approved
waste streams are in the Operations Plan - Allen Steam Station North Starter Landfill
(3619-INDUS) Revision 0 (Operations Plan; AECOM, 2020).
Interim approval to place CCR as interim cover in the NSLF was granted by NCDEQ in a
letter dated October 2, 2024. Final approval of NSLF operations was granted on
December 13, 2023, upon receipt of NCDEQ's approval of the NSLF Construction
Certification Report, Volumes 1 through 4 (FID 1812557, 1818489, 1818100, and
1821726) which contained construction quality assurance information. The landfill began
operating on December 14, 2023.
Page 1

Environmental Controls Monitoring Semiannual Report December 2023 through March 2024
North Starter Landfill 3619-INDUS
1.1.2 Leachate Basin
The approximate 3-acre Leachate Basin is located within the northwestern portion of the
Active Ash Basin (AAB) and is bounded by the RAB to the north, AAB to the east and
south, and upland areas to the west (Drawing 2).
Leachate is conveyed from the NSLF to the Leachate Basin via a force main piping
network. The leachate basin ties into an existing 36-inch wastewater force main where it
is comingled with Plant wastewater and subsequently sent to the Lined Retention Basin
(LRB) for treatment. Flows from the LRB are discharged to the Catawba River (Lake
Wylie) through Outfall 006 in accordance with National Pollutant Discharge Elimination
System (NPDES) Permit NC0004979 (Drawing 2). The Leachate Basin engineered
base liner is designed with an LDS to monitor the integrity of the liner system.
Interim approval for operation of a temporary pumping system and to place CCR as
interim cover in the Leachate Basin was granted by NCDEQ in a letter dated October 2,
2024. Final approval of Leachate Basin operation was granted on November 14, 2023,
after the permanent pumping system was in place and upon receipt of NCDEQ's
approval of the Leachate Basin Construction Certification Report, Volumes 1 through 3
(FID 1776828, 1818490, and 1820954) which contained construction quality assurance
information. The Leachate Basin began operating on November 14, 2023.
1.1.3 Construction Drain
The NSLF is constructed with a network of 6-inch high -density polyethylene (HDPE) DR-
11 perforated pipes located laterally under the NSLF's bottom liner in the southeastern
portion of the landfill (Drawing 2). The pipes are surrounded by 6 inches of stone with a
geotextile wrap and convey collected groundwater for discharge via 6-inch solid HDPE
DR-11 piping. The construction drain inverts are designed to be 5 feet below the base of
the compacted soil liner elevation. The construction drain was completed in June 2022
and has been operational since that time.
Construction drain outlet sample locations are designated as ALN-NSLF-CD1 and ALN-
NSLF-CD2 and are at the terminus of discharge pipes located south of the southeastern
corner of the NSLF (Drawing 2). At the time of this report, ALN-NSLF-CD1 is sealed off
with a blind flange and is not anticipated to be used for construction drain discharge for
the remaining duration of construction drain operation. Therefore, construction drain
discharge samples are currently collected from ALN-NSLF-CD2; however, in special
cases, construction drain discharge flows could be switched to ALN-NSLF-CD1 if
needed. Only one construction drain discharge pipe is anticipated to be operational at a
time.
1.1.4 Surface Water
Stormwater in the vicinity of the NSLF is directed via channels around the perimeter of
the landfill to an NPDES-permitted wastewater unit or NPDES-permitted outfall.

1.2 Summary of Site Geology and Hydrology
The groundwater system at Allen is consistent with the regolith-fractured rock system and is
characterized as an unconfined, interconnected aquifer system indicative of the Piedmont
physiographic province in which the Site is contained. The groundwater system at the Site is
divided into the following three layers to distinguish the interconnected groundwater system:
the shallow flow zone, the deep (transition zone) flow zone, and the bedrock flow zone.
The ash basins, DORS Fills, RAB Ash Landfill, NSLF, and leachate basin are contained within
former perennial stream valleys [flow compartment] (Drawing 1). Groundwater within the flow
compartment is a flow -through system. Groundwater enters the system from the upgradient
end near the NSLF and flows beneath the NSLF and laterally through the central portion of the
system and downward near the RAB dam. Beyond the dam, groundwater flows toward and
discharges to the Catawba River (Lake Wylie). A groundwater divide is located primarily west
of the Site, upgradient of the NSLF and roughly follows topography along South Point Road
and topographic highs north of the RAB along Plant Allen Road to the Discharge Canal and
south of the AAB near Reese Wilson Road. The topographically controlled flow direction
provides natural hydraulic control of potential constituent migration in groundwater from the
NSLF, ash basins, and adjacent sources within the flow compartment.

2.0 Monitoring, Sampling, and Analysis Locations and Methods
2.1 Leak Detection System Monitoring
Leak detection monitoring occurs in the vicinity of the landfill sump (ALN-NSLF-LDS1) and in
the vicinity of the leachate basin (ALN-LDSC) (Drawing 2).
Performance of the LDS is determined by the average monthly quantity of liquid removed from
the leak detection layer. Each leak detection discharge pump is equipped with a pump totalizer
(flow meter). The flow meter rates were monitored and recorded as defined in the Operations
Plan (AECOM, 2020).
Leak detection monitoring results are summarized in Section 3.1.
2.2 Leachate Sampling and Analysis
A discrete leachate sample was collected from location ALN-NSLF-LCS1, located in the
vicinity of the landfill sump from the leachate collection discharge. A comprehensive leachate
sample was collected from the leachate basin sump (ALN-LCSC) located in the vicinity of the
corresponding sump header. Both samples were collected on March 4, 2024. Leachate
sample locations are shown on Drawing 2.
Duke Energy personnel collected samples and documented the sampling in accordance with
procedures provided in Duke Energy's Landfill Sample Collection Guideline (SynTerra, 2023
Appendix 1).
Copies of the field calibration and sampling forms are included in Appendix A. The
parameters and constituents reported were sampled in accordance with Table 1 of the
approved ECMP. Constituents were analyzed by Duke Energy Analytical Laboratory (North
Carolina Laboratory Certification #248). The laboratory report and chain -of -custody (COC)
forms are included in Appendix B.
The leachate samples were measured for the following parameters in the field:
• pH, specific conductivity, temperature, dissolved oxygen, oxidation-reduction potential
using a water quality meter
• Turbidity using a turbidity meter
The leachate samples were analyzed in the laboratory for the following constituents:
• Barium, boron, calcium, iron, lithium, magnesium, manganese, and zinc using U.S.
Environmental Protection Agency (USEPA) Method 601 OD
• Antimony, arsenic, beryllium, cadmium, chromium, cobalt, copper, lead, molybdenum,
nickel, selenium, thallium, and vanadium using USEPA Method 6020B
• Chloride, fluoride, nitrate (as nitrogen), and sulfate using USEPA Method 9056A
• Mercury using USEPA Method 7470A

• Silver using USEPA Method 6020A
• Total dissolved solids using Standard Method (SM) 2540C
Leachate field parameters and analytical results are summarized in Section 3.2.
2.3 Construction Drain Outlet Sampling and Analysis
A construction drain outlet sample was collected from sample location ALN-NSLF-CD2 on
March 27, 2024 (Drawing 2).
Copies of the field calibration and sampling forms are included in Appendix A. The
parameters and constituents reported were sampled in accordance with Table 1 of the
approved ECMP. Constituents were analyzed by Duke Energy Analytical Laboratory. The
laboratory report and COC forms are included in Appendix B.
The construction drain outlet sample was measured for the same set of parameters and
constituents as the leachate samples (listed in Section 2.2) and the following additional
parameters:
• Beryllium (dissolved), cadmium (dissolved), chromium (dissolved), copper (dissolved),
lead (dissolved), and nickel (dissolved) using USEPA Method 6020B
• Silver (dissolved) using USEPA Method 6020A
• Total hardness and zinc (dissolved) using USEPA Method 6010D
Construction drain outlet field parameters and analytical results are summarized in
Section 3.3.
2.4 Surface Water Sampling and Analysis
Surface water sampling is currently not required for the NSLF.

3.0 Monitoring, Sampling, and Analysis Results
3.1 Leak Detection System Monitoring Results
No exceedances of the initial response leakage rate (IRLR) and action leakage rate (ALR)
occurred during the reporting period.
An average daily leakage rate is calculated for the operational NSLF each month and
compared to the IRLR and ALR for the landfill LDS as defined in the Operations Plan
(AECOM, 2020).
Average daily leakage rates for the NSLF were calculated as follows:
1. Calculate the monthly total volume pumped (gallons):
monthly volume pumped (gallons) = current month total flow meter reading — preceding month
total flow meter reading
2. Calculate the average daily leakage rate [gallons per acre per day (gpad)]:
average daily leakage rate (gpad) = monthly volume pumped (gallons) - landfill cell area (acres)
monitoring duration (days)
The LDS monitoring results for location ALN-NSLF-LDS1 are included in Table 1A, and the
LDS monitoring results for location ALN-LDSC are included in Table 1 B. The LDS leakage rate
data collection details are kept with on -Site records.
Below are note(s) for variances in data (e.g., total volume pumped).
No leakage rates or notable variances in the data outside of the normal operating range for the
landfill were observed during the monitoring period.
3.2 Leachate and Analytical Results
Leachate analytical results are not compared to surface water or groundwater quality
standards.
The leachate analytical results for samples ALN-NSLF-LCS1 and ALN-LCSC are included in
Table 2.
As normal laboratory practice, select samples were diluted to bring samples within the
calibrated range of analysis. Specifics regarding the diluted samples, including the dilution
factor, are reported in the electronic data deliverable (EDD) and the laboratory analytical
report. The laboratory analytical report, data validation checklist, and COC form associated
with data collected as part of this semiannual monitoring period are included in Appendix B.

North Starter Landfill 3619-INDUS
3.3 Construction Drain Outlet Analytical Results
Construction drain outlet analytical results are not compared to surface water or groundwater
quality standards.
The construction drain outlet analytical results for sample ALN-NSLF-CD2 are included in
Table 3.
The construction drain outlet sample is included in the same laboratory analytical report, data
validation checklist, and COC form as the leachate data collected as part of this semiannual
monitoring period (Appendix B).
3.4 Surface Water Analytical Results
Surface water sampling is currently not required for the NSLF; therefore, there are no
analytical results to report.

Notes:
1 Monitoring began on December 11, 2023, three days prior to commencing landfill operations on December 14, 2023.
Z January 2024 monitoring duration is 35-days, and includes the last 4-days of operation in December 2023 because the landfill pump flows were not tied into the Plant Digital
Control System (DCS) in time to evaluate the LDS operational days in December 2023 separate from January 2024.

Lab Qualifiers:
J—Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
M4 —The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level; the associated LCS recovery was acceptable.
R1— Relative Percent Difference exceeded method acceptance limits.
Validation Qualifiers:
R— Result is unusable. The sample result is rejected due to serious deficiencies in meeting quality control criteria; the analyte may or may not be present in the sample.
J — Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
U—Analyte was analyzed form but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B —Target analyte detected in the method blank an in the sample at a concentration less than 10x the blank concentration.
• Sulfate MS % recovery low (MSD ok) and RPD > 20% for LCSC (M4,111); Rl qualifier missing on lab report and EDD.
• Boron (0.007 mg/L) and Lithium (0.002 mg/L) was detected in the Field Blank; these analytes were not detected in the samples at concentrations less than 10x the blank concentrations.

J—Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
Validation Qualifiers:
R— Result is unusable. The sample result is rejected due to serious deficiencies in meeting quality control criteria; the analyte may or may not be present in the sample.
J — Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
U—Analyte was analyzed form but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B —Target analyte detected in the method blank an in the sample at a concentration less than 10x the blank concentration.
