Wood Environment & Infrastructure Solutions, Inc. 1308-C Patton Avenue Asheville, NC 28806 USA Subject: Report of October 2020 Stormwater Discharge Sampling BorgWarner Turbo Systems Arden, North Carolina Wood Project 6252-16-0240.06 Dear Mr. Martindale: T: 828-252-8130 www.woodplc.com Wood Environment & Infrastructure Solutions, Inc. (Wood) is pleased to submit this Report of October 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 BorgWarner Turbo Systems — October 2020 Stormwater Discharge Sampling Report November 16, 2020 Wood Project 6252-16-0240.06 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 relation to the exceedance of zinc at OF-3. The results of the investigative sampling were included in a separate report. In summary, the old dock roof, new dock roof, Coolant Room roof, and likely the Steam Room roof each appear to be a source of zinc in stormwater ultimately detected at the downstream outfall OF-3 location. This report addresses the monthly sampling component of the Tier Two response for outfall OF-3. October 2020 Stormwater Sampling Activities Wood personnel were onsite to perform stormwater sampling during a measureable storm event on October 23, 2020. The storm event occurred between approximately 2:30 PM and 3:30 PM on October 23, 2020. Wood personnel performed stormwater sampling of the discharge starting at approximately 3:10 PM when constant measureable discharge was produced. Total rainfall for this event was 0.33 inches as measured at the on -site rain gauge the same 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 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). In addition to analytical monitoring, Wood performed qualitative monitoring at 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, BorgWarner Turbo Systems — October 2020 Stormwater Discharge Sampling Report November 76, 2020 Wood Project 6252-16-0240.06 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 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 sample collected from outfall OF-3 (0.490 mg/L). Additionally, the concentration of copper detected in the sample collected from outfall OF-3 (0.0315 mg/L) exceeded the NCDEQ benchmark value 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 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. Although above the NCDEQ benchmark value, the zinc concentration detected at outfall OF-3 indicated in this report is within the range of concentrations that have been previously detected and reported during the period of regulatory relief. Based on the October 2020 sampling results, a continued Tier Two and a Tier Three response is warranted at outfall OF-3. This sample represents the fourth copper concentration detected at outfall OF-3 above the benchmark value during this permit period. Wood recommends contacting the NCDEQ regional office contact, as per the Tier Three response requirements in relation to the sixth consecutive detection of zinc and fourth 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 BorgWarner Turbo Systems — October 2020 Stormwater Discharge Sampling Report Wood Project 6252-16-0240.06 November 16, 2020 • 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. Recommendations for potentially reducing the concentration of zinc detected in samples collected at outfall OF-3 are included in the investigative report. The investigative sampling event also indicates 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 Reports, to NCDEQ for their files.

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 J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision.
