Subject: Report of March 2020 Stormwater Discharge Sampling
BorgWarner Turbo Systems
Arden, North Carolina
Wood Project 6252-16-0240.06
Dear Mr. Martindale:
Wood Environment&Infrastructure Solutions, Inc. (Wood) is pleased to submit this Report of March 2020
Stormwater Discharge Sampling for the BorgWarner 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 two consecutive detections of zinc above the NCDEQ benchmark value in June and October
2019, a Tier Two response was implemented at outfall OF-3.This report addresses the monthly sampling
component of the Tier Two response for outfall OF-3, as well as the 'regular'semi-annual sampling of
outfall OF-1.
March 2020 Stormwater Sampling Activities
Wood personnel were onsite to perform stormwater sampling during a measureable storm event on
March 31, 2020.The storm event occurred between approximately 10:00 AM and 1:00 PM on March 31,
2020.Wood personnel performed stormwater sampling of the discharges starting at approximately 12:05
PM when constant measureable discharge was produced.Total rainfall for this event was 0.16 inches as
measured at the on-site rain gauge the following day after the samples were collected. Rainfall sufficient
to produce a measureable discharge was not recorded during the 72 hours prior to this measurable storm
event.
Within about 30 minutes of constant measurable discharge,the pH of the stormwater was measured with
a calibrated pH meter, and stormwater samples were collected from representative 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 each stormwater
discharge outfall associated with industrial activity.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 for outfalls OF-1, OF-2, and OF-3 are
attached to this report.

Borg Warner Turbo Systems—March 2020 Stormwater Discharge Sampling Report Moy 13,2020
Wood Project 6252-16-0240.06
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 of
0.126 milligrams per liter(mg/L) in the samples collected from outfalls OF-1 (0.202 mg/L) and OF-3 (0.537
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 previous sampling results indicating that industrial processes are not a significant contributor to
the zinc and copper concentrations, NCDEQ had granted a regulatory relief exemption to the zinc and
copper benchmarks; however,the regulatory relief expired with the general permit in November 2018.
The zinc data value for OF-3 indicated in this report is above the range of concentrations that have been
previously detected and reported, and the zinc data value for OF-1 is within range of concentrations that
have been previously detected and reported. Based on the March 2020 sampling results, a Tier One
response is warranted at Outfall OF-1 and a Tier Three response is warranted at outfall OF-3.
Wood recommends that the following list of requirements for a Tier One response be performed at the
facility in relation to the detection of zinc above the benchmark value at OF-1:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or
physical improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. Record this instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the
selected actions, and the date the selected actions were implemented.

Borg Warner Turbo Systems—March 2020 Stormwater Discharge Sampling Report May 13,2020
Wood Project 6252-16-0240.06
Wood recommends contacting the NCDEQ regional office contact, as per the Tier Three response
requirements in relation to the fourth consecutive detection of zinc 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;
• Require the permittee to continue Tier Three obligations through the permit renewal process.
In addition to this semi-annual stormwater sampling event,Wood conducted investigative sampling in
relation to the exceedance of zinc at OF-3.The results of the investigative sampling are included in a
separate report.In summary,the roofs in the dock area appear to be a potential source of zinc in
stormwater detected at outfall OF-3.
Wood recommends submitting this documentation of stormwater sampling, along with the attached
Stormwater Discharge Outfall Monitoring Report, to NCDEQ for their files.

The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
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 Ss
MDL Method Detection Limit.
4
ND Not detected at the Reporting Limit(or MDL where applicable). Cn
RDL Reported Detection Limit.
Rec. Recovery. 5 Sr
RPD Relative Percent Difference.
SDG Sample Delivery Group.
U Not detected at the Reporting Limit(or MDL where applicable). Qc
Analyte 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 GI
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. Al
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. s
The non-spiked sample in the prep batch used to determine the Relative Percent Difference(RPD)from a quality control SC
Original Sample 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 Confidence level of 2 sigma.
(Radiochemistry)
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.
