RE: NPDES COMPLIANCE SUBMITTAL FOR FIRST QUARTER 2024
HIGH POINT CONSTRUCTION AND DEMOLITION LANDFILL
GUILFORD COUNTY, NORTH CAROLINA, PERMIT NO. NCG120099
To Whom It May Concern,
WI High Point Landfill, LLC (WI High Point) is monitoring stormwater under Permit No.
NCG120099 at the High Point Construction and Demolition Landfill located at 5830 Riverdale
Drive, Jamestown, North Carolina (NC). Quarterly stormwater samples were collected during a
qualifying rainfall event from outfalls SB-1, SB-8, and ST-1 on March 6, 2024.
Results were noted above the benchmark values for chemical oxygen demand (COD), fecal
coliform, and total suspended solids (TSS) in samples collected from one or more sampling
locations during the March 2024 sampling event. COD and fecal coliform were observed at
concentrations above the benchmark value in samples collected from ST-1. TSS was observed
at concentrations above the benchmark value in samples collected from ST-1 and SB-8. The
detections of COD and TSS in samples collected from ST-1 represents the second consecutive
sampling event where concentrations above the benchmark values were noted for these
parameters. As such, WI High Point Landfill, LLC is implementing Tier II (i.e., monthly monitoring
of stormwater location ST-1). The location ST-1 is downstream from one of the facility's
stormwater retention ponds. This pond is currently under construction to implement best
management practices which should improve stormwater quality at this location. In response to
the above benchmark concentration of TSS observed at sample location SB-8, WI High Point is
implementing a Tier I response to address stormwater quality at this location.
As noted, there was no discharge during operational hours for the first quarter compliance period
for outfall SB-2 during a qualifying rainfall event. The Stormwater Discharge Monitoring Report
(DMR) is attached.
If you have any questions or require any additional information, please contact us. We
appreciate your assistance with this project.

Sincerely,
WI High Point Landfill, LLC

QUALIFIERS
Project: High Point C&D Landfill
Pace Project No.: 92717085
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
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
R1 RPD value was outside control limits.
u2 Colonies are too numerous to count. Actual result may be greater than reported.
