MONTHLY NPDES COMPLIANCE SUBMITTAL—JUNE 2023 EVENT
GREAT OAK LANDFILL, RANDOLPH COUNTY, NORTH CAROLINA
PERMIT NO. NCG120107
To Whom It May Concern:
Stormwater monitoring is performed at the Great Oak Landfill under Permit No. NCG120107. The purpose of this
correspondence is to provide the Stormwater Discharge Monitoring Report(DMR)for June 2023. Stormwater
samples were collected from outfalls Pond-2, Pond-3, and Pond-4 on June 19, 2023 and sent to Pace Analytical
in Huntersville, NC for analysis. Pond-1 did not discharge during the June 2023 sampling event. Chemical
oxygen demand (COD) and total suspended solids (TSS)were detected above the benchmark values during this
stormwater sampling event. Fecal coliform samples collected from the ponds were not analyzed due to an error
during the incubation process at the lab which caused the samples to exceed the method hold time requirements.
If you have any questions or require any additional information, please contact us. We appreciate your assistance
with this project.
Sincerely,
WSP USA INC.

All permits require qualitative monitoring to be performed during a"measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DEMLR
Regional Office.

QUALIFIERS
Project: Great Oak Landfill
Pace Project No.: 92673248
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.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
R1 RPD value was outside control limits.
