Subject: Semi-annual Leachate Sampling Results — September 2021
Duke Energy Carolinas, LLC
Allen Steam Station
Retired Ash Basin Ash Landfill, Phase I, Cells 1 and 2, Permit #36-12
Dear Ms. Moutos:
In accordance with the current landfill Operations Plan, Duke Energy is providing the results of semi-
annual leachate sampling for the Allen Steam Station (Allen or Station) Retired Ash Basin (RAB) Ash
Landfill located in Gaston County, North Carolina.
On August 31, 2021, leachate samples were collected from the leachate collection system at sample
ports for Cell 1 and Cell 2 as depicted on Figure 1. The samples were collected by Duke Energy
personnel. A summary of sampling results can be found in Table 1. Laboratory analytical and field
forms are provided as Attachments 1 and 2, respectively. The parameters tested are not bound by state
groundwater or surface water standards.
The Allen RAB Ash Landfill leachate is sampled semi-annually during March and September. The next
landfill leachate sampling event will occur during March 2022 with documentation to follow.
If you have any questions or concerns, please contact me at 704-382-7171 or at
Courtney.Murphy(o-)duke-energy.com.
Sincerely,
dw�w- ff"

Notice: This form and any information attached to it are "Public Records" as defined in NC General Statute 132-1 As such, these documents are
available for inspection and examination by any person upon request (NC General Statute 132-6)
Instructions:
Prepare one form for each individually monitored unit.
• Please type or print legibly.
• Attach a notification table with values that attain or exceed NC 2L groundwater standards or NC 2B surface water standards. The notification
must include a preliminary analysis of the cause and significance of each value. (e g naturally occurring, off -site source, pre-existing
condition, etc.).
• Attach a notification table of any groundwater or surface water values that equal or exceed the reporting limits.
• Attach a notification table of any methane gas values that attain or exceed explosive gas levels This includes any structures on or nearby the
facility (NCAC 13B 1629 (4)(a)(i).
• Send the original signed and sealed form, any tables, and Electronic Data Deliverable to: Compliance Unit, NCDENR-DWM Solid Waste

Program Comments:
QC Note:
Page 1 of 30
LCS_CELL-1 Hg MS/MSD recoveries fell below the QC limits. The blank and LCS were within the control limits. The sample
result should be considered an estimate.
Nitrate (0.28 mg/L) and boron (0.125 mg/L) were detected in the field blank.
Data Flags & Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of
the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except
in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The
order of individual sections within this report is as follows:
Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis,
Analytical Laboratory QC Reports, Sub -contracted Laboratory Results, Customer Specific Data Sheets, Reports &
Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC)
Certification:
The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina
(DHEC) Laboratory ID # 99005. Contact the Analytical Laboratory for definitive information about the certification status of
specific methods.

QUALIFIERS
Project: J21080226 ALN LCS
Pace Project No.: 92558935
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
