Subject: Report of February 2021 Stormwater Discharge Sampling
BorgWarner Emissions, Thermal, and Turbo Systems
Arden, North Carolina
Wood Project 6252-16-0240.07
Dear Mr. Martindale:
T:828-252-8130
www.woodplc.com
Wood Environment & Infrastructure Solutions, Inc. (Wood) is pleased to submit this Report of February
2021 Stormwater Discharge Sampling for the BorgWarner Emissions, Thermal, and Turbo Systems facility
located on Brevard Road in Arden, North Carolina. This sampling was performed to comply with
requirements contained in the General Permit for Stormwater Discharge (Permit NCG030000 effective
November 1, 2018 issued by the North Carolina Department of Environmental Quality (NCDEQ).
BorgWarner's certificate of coverage under this permit is NCG030075.
Background Information
Seven stormwater outfalls are located at the site, as shown on the attached Figure 1. In 2015, NCDEQ
approved a request for representative outfall status, whereby outfalls OF-1 and OF-3 are the only outfalls
to be sampled. The outfalls discharge directly and indirectly into Clayton Creek prior to Clayton Creek's
confluence with the French Broad River. According to NCDEQ's water quality classification of the French
Broad River basin, Clayton Creek and the adjacent portion of the French Broad River are not currently
classified as the following sensitive receiving waters: Outstanding Resource Waters, High Quality Waters,
Primary Nursery Areas and Trout Waters. Therefore, the more protective benchmark value listed in the
General Permit for total suspended solids (50mg/L) does not apply to stormwater discharges at the site —
the applicable benchmark value for total suspended solids is 100 mg/L. A rain gauge is present at the site
North Carolina Corporate Engineering License No. F-1253; Geology No. C-247

approximately six feet above ground in an open area at a distance of at least twice the height of
surrounding structures.
Because of consecutive detections of zinc above the NCDEQ benchmark value, a Tier Two response was
implemented at outfall OF-3 in early 2020. In addition to semi-annual stormwater sampling, Wood
conducted investigative sampling in March and September in relation to the exceedances of zinc at OF-3.
The results of the investigative sampling were included in separate investigative reports. In summary, the
old dock roof, new dock roof, Coolant Room roof, and likely the Steam Room roof each appear to be a
potential source of zinc in stormwater ultimately detected at the downstream outfall OF-3 location. In
response to the results of the investigative sampling, BorgWarner painted the old dock roof. This report
addresses the monthly sampling component of the Tiered response for outfall OF-3 as well as the 'regular'
semi-annual sampling of outfall OF-1.
February 2021 Stormwater Sampling Activities
Wood personnel were onsite to perform stormwater sampling during a measureable storm event on
February 26, 2021. The storm event occurred between approximately 11:00 AM on February 26, 2021 to
4:00 AM on February 27, 2021. Wood personnel performed stormwater sampling of the discharges
starting at approximately 11:30 AM, approximately 30 minutes after constant measurable discharges were
produced. Total rainfall for this event was 0.67 inches. Approximately 0.13 inches of rainfall was measured
at the on -site rain gauge following sample collection. Rainfall sufficient to produce a measureable
discharge was not recorded during the 72 hours prior to this measureable storm event.
Within about 30 minutes of constant measureable discharge, the pH of the Stormwater was measured
with a calibrated pH meter, and stormwater samples were collected from outfalls OF-1 and OF-3. The
samples were packed in an ice -chilled cooler and delivered with chain -of -custody via overnight courier to
Pace Analytical in Mt. Juliet, Tennessee (a North Carolina -accredited laboratory) for analysis. The outfall
samples were submitted for analysis of total lead, total zinc, and total copper according to Standard
Method 6020B, total suspended solids (TSS) according to Standard Method 2540D, and non -polar oil and
grease according to EPA Method 1664B (SGT-HEM).

In addition to analytical monitoring, Wood performed qualitative monitoring at industrial stormwater
discharge outfalls OF-1, OF-2 and OF-3. The qualitative monitoring included the observation of the
following discharge characteristics: color, odor, clarity, floating solids, suspended solids, foam, oil sheen,
erosion or deposition, and other obvious indicators of stormwater pollution. The completed Stormwater
Discharge Outfall Qualitative Monitoring Reports are attached to this report.
Field analysis of the stormwater samples indicated pH readings were within the NCDEQ benchmark range.
Laboratory analytical results indicated the concentration of zinc exceeded the NCDEQ benchmark value
(benchmark) of 0.126 milligrams per liter (mg/L) in the sample collected from outfall OF-3 (0.238 mg/L).
The concentration of copper (0.0104) exceeded the benchmark of 0.010 mg/L. The remaining monitored
parameters were below their respective NCDEQ benchmark values. The analytical results for the outfall
samples are reported on the attached NCDEQ Semi -Annual Stormwater Discharge Monitoring Report. The
laboratory analytical report and chain of custody records are attached to this report.
Based on the February 2021 sampling results, a continued Tier Two and a Tier Three response is warranted
at outfall OF-3.
Wood recommends contacting the NCDEQ regional office contact, as per the Tier Three response
requirements in relation to the ninth consecutive detection of zinc and seventh detection of copper within
this permit period above the benchmark value at OF-3. The NCDEQ regional office contact may complete
the following in relation to the Tier Three response:
• Require that the permittee revise, increase, or decrease the monitoring and reporting frequency
for some or all of the parameters herein;
• Require sampling of additional or substitute parameters;
• Require the permittee to install structural stormwater control measures;
• Require the permittee to implement other best management practices;
• Require the permittee to perform upstream and downstream monitoring to characterize impacts
on receiving waters; or
• Require the permittee implement site modifications to qualify for a No Exposure Exclusion;
0 Require the permittee to continue Tier Three obligations through the permit renewal process.

The painting of the old dock roof appears to have improved zinc concentrations; however, the results
indicate additional mitigation may still be required to reduce zinc concentrations to below benchmark
values. The investigative sampling events also indicate that the roofs are not contributing to the elevated
copper concentrations occasionally detected at outfall OF-3. The copper concentration detected in a
surface runoff sample indicates the copper concentration is likely a ground surface source.
Wood recommends submitting this documentation of stormwater sampling, along with the attached
Stormwater Discharge Outfall Monitoring Report, to NCDEQ for their files.
We appreciate the opportunity to provide water resource services on this project. If you should have any

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
IDP
intended as a comprehensive explanation, and ifyou have additional questions please contact your project representative.
Results Disclaimer - Information
that may be provided by the customer, and contained within this report, include Permit Limits,Project Name,
FC
Sample ID, Sample Matrix,
Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/rimes, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
E
l MDL
ND
Method Detection Limit.
Not detected at the Reporting Limit (or MDL where applicable).
Rn
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
El
SDG
Sample Delivery Group.
U
Not detected at the Reporting Limit (or MDL where applicable).
RC
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
0
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
FAI
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
e
SC
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier
Description
J3
The associated batch QC was outside the established quality control range for precision.
P1
RPD value not applicable for sample concentrations less than 5 times the reporting limit.
