Subject: Report of March 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.woodpic.com
Wood Environment & Infrastructure Solutions, Inc. (Wood) is pleased to submit this Report of March 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 of 2020 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 third monthly sampling component of the Tiered response for outfall OF-3 since
painting the old dock roof.
March 2021 Stormwater Sampling Activities
Wood personnel were onsite to perform stormwater sampling during a measureable storm event on
March 25, 2021. The storm event occurred between approximately 9:00 AM on March 25, 2021 and 3:00
PM on March 25, 2021. Wood personnel performed stormwater sampling of the discharge starting at
approximately 10:00 AM, approximately 30 minutes after constant measurable discharges were produced.
Total rainfall for this event was 3.68 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 a stormwater sample was collected from outfall OF-3. The sample was
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 sample
was 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).

March 2021 Stormwater Discharge Sampling Report
Wood Project 6252-16-0240.07
April 15, 2021
In addition to analytical monitoring, Wood performed qualitative monitoring at industrial stormwater
discharge outfall 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 Report is attached to this report.
Field analysis of the stormwater sample indicated the pH reading was within the NCDEQ benchmark
range. Laboratory analytical results indicated the monitored parameters were below their respective
NCDEQ benchmark values. The analytical results for the outfall samples are reported on the attached
NCDEQ Stormwater Discharge Monitoring Report (DMR) Form for NCG030000 Metal Fabrication. The
laboratory analytical report and chain of custody records are also attached to this report.
Based on the 2021 sampling results completed since painting the old dock roof, concentrations of zinc
appear to be decreasing. The current NCG03000 general permit period is scheduled to expire on May 31,
2021. As described in the general permit, Tier Two and Tier Three requirements are to continue through
the permit renewal process.
Wood recommends submitting the attached Stormwater Discharge Monitoring Report to NCDEQ for their
files. Based on the previous detections of zinc and copper above the benchmark values 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.

March 2021 Stormwater Discharge Sampling Report
Wood Project 6252-15-0240.07
April 15, 2021
The painting of the old dock roof appears to have improved zinc concentrations, with this sampling
event's reported concentration below the benchmark value; however, continued monitoring will be
required to determine if additional mitigation might be required to maintain zinc concentrations below
the benchmark value. The investigative sampling events also indicate that the roofs are not contributing
to the elevated copper concentrations occasionally detected at outfall OF-3.
We appreciate the opportunity to provide water resource services on this project. If you should have any
questions, or need additional information, please do not hesitate to contact us at [phone].

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 pennittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the pennittee obtains approval from the local DEMLR
Office.

intended as a comprehensive explanation, and if you 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,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes

If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
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
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.
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)
