(AMEC) is pleased to submit this letter report of stormwater discharge sampling and analysis for the Continental Automotive Systems facility located at One Quality Way in Fletcher, North Carolina. This sampling was performed to comply with the requirements contained in the General Permit for Stormwater Discharge (Permit NCG030000 effective November 1, 2012, and expires October 31, 2017) issued by the North Carolina Department of Environment and Natural Resources (NCDENR). The Continental Automotive Systems certificate of coverage under this permit is NCG030572. Six stormwater outfalls are located at the site, as shown on the attached Figure 1. The outfalls discharge indirectly into an unnamed tributary of McDowell Creek prior to McDowell Creek's confluence with the French Broad River. According to NCDENR's water quality classification of the French Broad River basin, McDowell 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 100mg/L. A rain gauge is present at the site approximately six feet above ground in an open area at a distance of at least twice the height of surrounding structures, and the nearby Asheville Regional Airport maintains a weather station which records precipitation. AMEC personnel were onsite to perform stormwater sampling during a Correspondence: AMEC Environment & Infrastructure, Inc. 1308 Patton Avenue Asheville, North Carolina 28806 Tel 828.252.8130 Continental Automotive Systems - Stormwater Discharge Sampling and Analysis December 2, 2014 AMEC Project 6252-14-0123 measureable storm event on October 3, 2014. The storm event occurred between approximately 9:00 AM and 1:00 PM on October 3, 2014. Total rainfall for this intermittent event was 0.44 inches as measured at the Asheville Regional Airport gauging station which is approximately one mile northeast of the site. AMEC personnel measured 0.39 inches of total rainfall for the event in the onsite rain gauge at the completion of stormwater sampling. Measureable rainfall was not recorded during the 72 hours prior to the measureable storm event. Within 30 minutes of constant, measurable discharge during the measurable storm event, the pH of the stormwater was measured with a calibrated pH meter and stormwater samples were collected from representative stormwater outfalls OF-i and OF-4. The samples were packed in an ice -chilled cooler and delivered with chain -of -custody via overnight courier to Environmental Science Corporation in Mt. Juliet, Tennessee (a North Carolina -accredited laboratory) for analysis of total lead and total zinc according to EPA Method 6010, total copper according to EPA Method 6020, total suspended solids (TSS) according to Standard Method 2540D and non -polar oil and grease according to EPA Method 1664A with silica -gel treatment and hexane extraction. Laboratory results are recorded on the attached NCDENR Semi -Annual Stormwater Discharge Monitoring Report. The laboratory report is also attached. Field analysis of the stormwater samples indicated the pH values for outfalls OF-1 and OF-4 were within the NCDENR benchmark range. Laboratory results indicate zinc was detected at a concentration that exceeds the NCDENR benchmark value at outfall OF-1, but not detected above the laboratory reporting limit from the outfall OF-4 sample. Laboratory results indicate concentrations of total suspended solids, non -polar oil and grease, lead and copper, if detected, are below NCDENR benchmark values in outfalls OF-1 and OF-4. As described in NCDENR's Relief from Monthly Stormwater Sampling letter, dated September 19, 2014, NCDENR granted temporary regulatory relief from the tiered responses previously required by exceedances of copper and zinc above NCDENR benchmarks for the duration of current permit period, which expires October 31, 2017. The concentration of zinc detected in the stormwater sample collected from outfall OF-1 is similar (e.g. same order of magnitude) to concentrations detected in the last four consecutive stormwater samples collected from outfall OF-1 during monthly sampling/tiered responses or semiannual sampling events. Based on 2 Continental Automotive Systems - Stormwater Discharge Sampling and Analysis December 2, 2014 AMEC Project 6252-14-0123 previous sampling results, the NCDENR's Relief from Monthly Stormwater Sampling letter, and the current detected concentration of zinc in OE-1 sample, AMEC does not recommend performing a Fier response or notifying NCDENR of the detected concentration of zinc at this time. AMEC recommends continuing with semiannual monitoring, with the next semiannual sampling event between January 1, 2015, and June 30, 2015. We appreciate the opportunity to provide water resource services on this project.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - i8 two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

(AMEC) is pleased to submit this letter report of stormwater discharge sampling for May 2014 and a request for regulatory relief from monthly stormwater sampling for the Continental Automotive Systems facility located at One Quality Way in Fletcher, North Carolina. This documentation was prepared to comply with the requirements contained in the General Permit for Stormwater Discharge (Permit NCG030000 effective November 1, 2012, and expiring October 31, 2017) issued by the North Carolina Department of Environment and Natural Resources (NCDENR). The Continental Automotive Systems certificate of coverage under this permit is;NCG030572. Background Information Six stormwater outfalls are located at the site, as shown on the attached Figure 1, with two outfalls (OF-1 and OF-4) designated as representative outfalls. A Tier Two response has been implemented at outfall OF-1 at the facility, due to the detection of zinc above the NCDENR benchmark value for two consecutive semi-annual sampling events in 2013, The Tier Two response requires monthly monitoring for parameters at each outfall where benchmark values for any monitored constituent have been exceeded for two consecutive monitoring periods. OF-1 was not able to be sampled in January and February 2014, as a measureable storm event producing a discharge at outfall OF-1 did not occur, as documented in the Stormwater Discharge Monitoring Reports submitted to NCDENR for Correspondence: AMEC Environment & Infrastructure, Inc. 1308 Patton Avenue Asheville, North Carolina 28806 Tel 828.252.8130 Fax 828.251.9600 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 these months.

In order to investigate potential sources of zinc and copper in the OF-1 drainage basin, Continental Automotive Systems conducted additional sub -drainage basin stormwater sampling, including collection of a sample of rainwater falling from the sky at the facility during the April and May 2014 stormwater sampling events. May 2014 Stormwater Sampling Activities AMEC personnel were onsite to perform stormwater sampling during a measureable storm event on May 14 and May 15, 2014. The storm event began at approximately 11:00 pm on May 14, 2014, and ended at approximately 7:00 am on May 15, 2014. Total rainfall for this intermittent event was 1.87 inches, as measured at the Asheville Regional Airport gauging station, which is approximately one mile northeast of the site. Measureable rainfall was not recorded during the 72 hours prior to the measureable storm event. Within 30 minutes of constant, measurable discharge during the storm event, the pH of the stormwater was measured with a calibrated pH meter, and stormwater samples were collected from representative stormwater outfall OF-1 and select sub -drainage basins associated with outfall OF-1. Additionally, a background rainfall sample was collected. Sub -drainage basin samples included stormwater collected at drop inlets, catch basins, and roof discharges associated with OF-1 (OF-1 C, OF-1 D, and OF-1 Roof). The samples were packed in an ice -chilled cooler and delivered with chain -of -custody via overnight courier to Environmental Science Corporation (a North Carolina -accredited laboratory) in Mt. Juliet, Tennessee, for analysis. Samples from OF-1 were submitted for analysis of total lead and total zinc according to EPA Method 6010, total copper according to EPA Method 6020, total suspended solids (TSS) according to Standard Method 2540D, and non -polar oil and grease according to EPA Method 1664A with silica -gel treatment and hexane extraction. Samples OF -IC, OF-1 D, OF-1 Roof, and the background rainfall sample were submitted for analysis of zinc and copper. Laboratory results for the sampling performed on May 14 and 15, 2014, are recorded on the attached NCDENR Semi -Annual Stormwater Discharge Monitoring Report. The laboratory report is also attached. Field analysis of the stormwater samples indicated that 2 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 pH values were within the NCDENR benchmark range. Laboratory results indicate the concentrations of copper and zinc exceed their respective NCDENR benchmark values in samples OF-1, OF-1C, and OF-11D, as shown in Table 1. The remaining monitored parameters were below their respective NCDENR benchmark values.

Concentrations of both zinc and copper were detected below their respective benchmark values and at concentrations below those detected in the outfall OF-1 and associated sub -drainage basin samples. Additionally, concentrations of zinc and copper detected in sample OF-1 Roof were below those detected in the background rainwater sample; thus, the roof does not appear to be a substantial source of zinc or copper detected in the stormwater samples. The detection of concentrations of zinc above the NCDENR benchmark value in outfall OF-1 for four consecutive reporting periods triggers a Tier Three response. Additionally, AMEC recommends that the following list of requirements for a Tier Two response be implemented at the facility in response to the detection of concentrations of copper above the NCDENR benchmark value in OF-1 for three consecutive reporting periods. The requirements for a Tier Two and Tier Three response are as follows: 3 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 1. Repeat all required actions outlined for a Tier One response, which include: • Conduct a stormwater management inspection of the facility within two weeks of receiving sampling results. • Identify and evaluate possible causes of the benchmark value exceedance. • Identify potential, and select the specific: source controls, operational controls, or physical improvements to reduce concentrations of the parameters of concern, or to bring concentrations to within the benchmark range. • Implement the selected actions within two months of the inspection. • Record each instance of a Tier One response in the Stormwater Pollution Prevention Plan (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. 2. Conduct all required actions outlined for a Tier Two response, which include: • Conduct monthly monitoring at each outfall where a sampling result exceeded the benchmark value for two consecutive samples (continue monthly monitoring for all parameters at outfalls OF-1). Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values or within benchmark range. • Submit a monthly monitoring report indicating "No Flow" if no discharge occurs during the sampling period. • Benchmark exceedances for a different parameter separately trigger a tiered response. • Maintain a record of the Tier Two response and monitoring results in the SPPP. 3. The Division of Water Quality may require the following actions (but are not limited to the following actions) for a Tier Three response, which include: • Requiring that the permittee revise, increase, or decrease monitoring frequency for some or all parameters; • Rescinding coverage under the General Permit, and requiring that the permittee apply for an individual stormwater discharge permit; • Requiring the permittee to install structural stormwater controls; • Requiring the permittee to implement other stormwater control measures; • Requiring the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters; or • Requiring the permittee implement site modifications to qualify for the No Exposure Exclusion. AMEC Site Visit Observations During a walkover of the property on May 9, 2014, AMEC personnel did not observe significant exposure of stormwater to materials involved in industrial processes in the 4 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 outfall OF-1 drainage basin. A loading dock with covered dock doors is located on the southern side of the building in the OF-1 drainage basin. New and recycled dunnage is stored under roof in this area. Other materials associated with the industrial process at the facility are not stored in this area. The ground surface in this area has recently been stabilized/vegetated since completion of construction of the dunnage storage structure. The roof drainage from the dunnage storage structure is discharged to the asphalt -paved ground surface and drains through the outfall OF-1 stormwater system. The roof drainage from the remaining southern portion of the building is not routed through outfall OF-1. During construction of additions to the facility in late 2013 and early 2014, a stormwater detention pond was constructed in the northern portion of the site. The detention pond is equipped with a forebay to capture sediment. The operation of this detention pond will aid in water quality parameters of water discharging to outfall OF-4. The pond will be maintained and inspected to continue proper operation. Review of Stormwater Activities Ample stormwater samples have been collected at the facility over an appropriate period of time to comply with the General Permit conditions. The concentrations of zinc detected in the samples collected from OF-1 range from 0.11 milligrams per liter (mg/L) to 0.16 mg/L, and the concentrations of copper detected in the samples range from 0.008 mg/L to 0.012 mg/L. 'Background' concentrations of zinc and copper have been detected in the rain falling from the sky prior to contact with the facility at 0.053 mg/L and 0.0061 mg/L, respectively. Monthly qualitative inspections and corrective actions have been made over the past year to minimize potential exposure of stormwater to materials and structures at the facility. A roll -up garage door at the chip handling area of the facility at the northwestern corner of the building was installed to prevent potential debris release to the outside. Additionally, the material storage area adjacent to the former oil/chemical storage area at the southwestern portion of the facility was previously under roof and is now both under roof and is enclosed, protecting the area from potential stormwater exposure from blowing rain. New, enclosed waste compactors, which are attached to the building, were installed, replacing existing compactors to more securely enclose waste. Roofing was also 5 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 incorporated in the design of the newly -constructed dunnage storage area to minimize the potential of stormwater exposure to dunnage materials. Continental Automotive Systems has initiated or implemented additional procedural processes and corrective actions. Continental Automotive Systems has procured bids for the rehabilitation/modification of the silt basin at outfall OF-1 and intends to implement modifications to the silt basin in 2014, Additional erosionisedimentation control measures have included the installation of erosion -control matting at the pavement's edge of the truck turnaround at the northern side of the facility and the re-vegetation/stabilization of the ground surface at the location of recently removed construction equipment and storage facilities. Additional actions taken have included maintenance to facility air scrubbers. Air scrubbers have been pressure -washed and cleaned, outfitted with new packing media, and are being operated with increased frequency of particulate removal under new operating and maintenance procedures as part of an ongoing preventive maintenance program. Tire wear has been reported to potentially be a contributing source of zinc to stormwater. Due to topographic and site boundary constraints, modifying the footprint of paved surfaces, particularly in the southern loading dock area within the OF-1 drainage basin, to mitigate truck tire wear because of tight turning radii is not feasible. The trucks utilizing the loading docks at the facility are not owned or operated by Continental. Facility forklifts do not typically operate outside the facility as part of the facility operations. Based on the June 8, 2010, NCDENR table, Estimated NC Stormwater Metals Benchmarks Based on Proposed Dissolved Water Quality Standards, the calculated revised stormwater benchmarks for zinc and copper are 0.126 mg/L and 0.0105 mglL, respectively. Based on these proposed values, all but two of the zinc and copper concentrations in outfall samples collected over the past year, as well as in many of the sub -drainage basin samples, are below the proposed benchmarks. AMEC notes that the proposed aquatic life water quality standards, upon which the benchmarks are based, are developed assuming a TSS value of 10 mg/L. The allowable benchmark contained in the General Permit for Stormwater Discharge is 100 mg/L (as applicable for this site with a receiving water classification of C), Concentrations of TSS in the outfall discharge samples have historically been detected between approximately 40 mg/L and 60 mg/L. 6 0 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 These higher TSS concentrations can potentially contribute to elevated total metals concentrations in relation to the total metals benchmark values. These elevated total metals concentrations do not necessarily correlate to elevated dissolved metals concentrations, which more closely represent the fraction of a total metal which is toxic to aquatic life and from which the benchmarks values are derived, but may indicate elevated concentrations of bound metals occurring in soil particles. Concentrations of zinc and copper in stormwater samples from representative outfalls OF- 1 and OF-4 during the past year are summarized in Table 2.

The roofing covering the dunnage storage area at the southern portion of the facility does not appear to be contributing to zinc and copper concentrations in the OF-1 drainage basin. Zinc and copper concentrations were above the current benchmark in runoff from the loading dock asphalt pavement in the southern portion of the property (samples 1C and 1D); however, these sub -basin concentrations did not appear to result in concentrations at the OF-1 discharge being above the proposed zinc and copper benchmarks in recent OF-1 sampling. 8 Continental Automotive Systems - Stomnwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 Ample stormwater samples have been collected from the designated outfall discharge locations, as well as from additional sub -drainage basins at the facility, to comply with the General Permit conditions. Continental has performed inspections and has modified and implemented additional stormwater pollution prevention measures and procedures over the past year, including design considerations for materials storage roofing/enclosures, stormwater detention, erosion prevention/control, and maintenance procedures on air scrubbers. These measures are described in this report, as well as previous reports. In addition, future measures are proposed, such as maintenance of the historical silt basin at outfall OF-1 and inspection/maintenance of the recently completed stormwater detention pond to the north of the facility in the outfall OF-4 drainage basin. Based on observations and evaluation of the facility's operations, industrial processes at the facility do not appear to impact stormwater by zinc and copper exposure. AMEC recommends submitting this documentation of sampling and the attached Semi- annual Stormwater Discharge Monitoring Report to NCDENR for their files, Request for Regulatory Relief On behalf of Continental Automotive Systems, AMEC requests a review for regulatory relief and a reduction of the current Tier Two monthly monitoring frequency to a semi- annual basis for zinc and copper. Semi-annual sampling and analysis for the full suite of General Permit parameters will be performed and evaluated for the remaining duration of the permit period, and tiered responses for benchmark exceedences of other parameters will be completed, if necessary. 9 Continental Automotive Systems - Stormwater Discharge Sampling for May 2014 June 16, 2014 AMEC Project 6252-14-0123 We appreciate the opportunity to provide water resource services on this project.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method blank - an aliquot of reagent water carried through the rntire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". 1f a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J611. The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water ca.rried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "05" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

(AMEC) is pleased to submit this letter report of stormwater discharge sampling for April 2014 for the Continental Automotive Systems facility located at One Quality Way in Fletcher, North Carolina. This documentation was prepared to comply with the requirements contained in the General Permit for Stormwater Discharge (Permit NCG030000 effective November 1, 2012, and expiring October 31, 2017) issued by the North Carolina Department of Environment and Natural Resources (NCDENR), The Continental Automotive Systems certificate of coverage under this permit is NCG030572. Six stormwater outfalls are located at the site, as shown on the attached Figure 1, with two outfalls (OF-1 and OF-4) designated as representative outfalls. A Tier Two response has been implemented at outfall OF-1 at the facility, due to the detection of zinc above the NCDENR benchmark value for two consecutive sampling events in 2013 (semi-annual sampling events, with the last event in December 2013). The Tier Two response requires monthly monitoring for parameters at each outfall where benchmark values for any monitored constituent have been exceeded for two consecutive monitoring periods. OF-1 was not able to be sampled in January and February 2014, as a measureable storm event producing a discharge at outfall OF-1 did not occur, as documented in the Stormwater Discharge Monitoring Reports submitted to NCDENR for these months. Correspondence: AMEC Environment & Infrastructure, Inc. 1308 Patton Avenue Asheville, North Carolina 28806 Tel 828.252.8130 Fax 828.251,9690 Continental Automotive Systems - Stormwater Discharge Sampling for April 2014 May 16, 2014 AMEC Project 6252-14-0123 AMEC personnel were onsite to perform stormwater sampling during a measureable storm event on April 14, 2014. The storm event began at approximately 11:00 AM on April 14, 2014, and ended on April 15, 2014. Total rainfall for this intermittent event was 0.94 inches as measured at the Asheville Regional Airport gauging station, which is approximately one mile northeast of the site. Measureable rainfall was not recorded during the 72 hours prior to the measureable storm event. Within 30 minutes of constant, measurable discharge during the measurable storm event, the pH of the stormwater was measured with a calibrated pH meter, and stormwater samples were collected from one representative stormwater outfall, OF-4, as well as from select sub -drainage basins associated with outfall OF-1. Measurable discharge from outfall OF-1 did not occur. Sub -drainage basin samples included stormwater at the inlets of drop inlets/catch basins associated with OF-1 (OF-1 B and OF-1 C). The samples were packed in an ice -chilled cooler and delivered with chain -of -custody via overnight courier to Environmental Science Corporation in Mt. Juliet, Tennessee (a North Carolina -accredited laboratory) for analysis. Samples from OF-4 were submitted for analysis of total lead and total zinc according to EPA Method 6010, total copper according to EPA Method 6020, total suspended solids (TSS) according to Standard Method 2540D and non -polar oil and grease according to EPA Method 1664A with silica -gel treatment and hexane extraction. Samples OF-1 B and OF-1 C were submitted for analysis of zinc and copper. Another storm event occurred in the late PM and early AM hours of April 28 and April 29, 2014. This storm was severe in nature with frequent lightning, high winds, and potential tornadoes; thus, because of safety concerns, sampling of a potential/likely measureable discharge at outfall OF-1 in the early AM hours of April 29, 2014, was not attempted. Laboratory results for the sampling performed on April 14, 2014, are recorded on the attached NCDENR Semi -Annual Stormwater Discharge Monitoring Report. The laboratory report is also attached. Field analysis of the stormwater samples indicated that pH values were within the NCDENR benchmark range. Laboratory results indicate the concentration of zinc exceeds the NCDENR benchmark value in sample OF-1 C, and concentrations of copper exceed the NCDENR benchmark value in samples OF-1B and OF- 1C, as shown in Table 1. The remaining monitored parameters were below their respective NCDENR benchmark values. 2 Continental Automotive Systems - Stormwater Discharge Sampling for April 2014 May 16, 2014 AMEC Project 6252-14-0123 Table 1: Stormwater Benchmarks and Monitoring Results for Sub -Drainage Basin Sampling Locations Associated with Outfall OF-1 Sub -Drainage Basin Sample Copper Concentration in mg/L Zinc Concentration in mg/L Benchmark-> 0.007 0.067 1 B 0.0071 0.055 1 C 0.020 0.32 Bald results Indicate results above respective benchmark prepared by 1=1-1- May d, zo14 checked by MEW May 9, 2014 AMEC recommends that the following list of requirements for a Tier Two response continue to be performed at the facility in response to the detection of concentrations of copper and zinc above their respective NCDENR benchmark values in outfall OF-1 for at least two consecutive reporting periods. Concentrations of zinc have been detected above the NCDENR benchmark value for three consecutive reporting periods, and concentrations of copper have been detected above the NCDENR benchmark value for two consecutive reporting periods. The requirements of a Tier Two response are as follows: 1. Repeat all required actions outlined for a Tier One response. 2. Conduct monthly monitoring at each outfall where a sampling result exceeded the benchmark value for two consecutive samples (continue monthly monitoring for all parameters at OF-1). Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values or within benchmark range. 3. Submit a monthly monitoring report indicating "No Flow" if no discharge occurs during the sampling period. 4. Benchmark exceedances for a different parameter separately trigger a tiered response. 5. Maintain a record of the Tier Two response and monitoring results in the SPPP. Based on the June 8, 2010, NCDENR table, Estimated NC Stormwater Metals Benchmarks Based on Proposed Dissolved Water Quality Standards, the calculated revised stormwater benchmarks for zinc and copper are 0.126 mg/L and 0.0105 mg/L, 3 Continental Automotive Systems - Stormwater Discharge Sampling for April 2014 May 16, 2014 AMEC Project 6252-14-0123 respectively. Based on these proposed values, some of the April 2014 outfall and sub - drainage basin zinc and copper concentrations, as well as previous sample concentrations, are below the proposed benchmarks. AMEC notes that the proposed aquatic life water quality standards, upon which the benchmarks are based, are developed assuming a TSS value of 10 mg/L. The allowable benchmark contained in the General Permit for Stormwater Discharge is 100 mg/L (as applicable for this site with a receiving water classification of C), Concentrations of TSS in the outfall discharge samples have historically been detected between approximately 40 mg/L and 60 mg/L. These higher TSS concentrations can potentially contribute to elevated total metals concentrations in relation to the total metals benchmark values, which are based on 10 mg/L TSS. These elevated total metals concentrations do not necessarily correlate to elevated dissolved metals concentrations, which more closely represent the fraction of a total metal which is toxic to aquatic life and from which the benchmarks values are derived, but may indicate elevated concentrations of bound metals occurring in soil particles. During a walkover of the northeastern portion of the property on May 9, 2014, AMEC personnel did not observe significant exposure of stormwater to materials involved in industrial processes in the outfall OF-1 drainage basin. A loading dock with covered dock doors is located on the southern side of the building in the OF-1 drainage basin. New and recycled dunnage is stored under roof in this area. Other materials associated with the industrial process at the facility are not stored in this area. The ground surface in this area has recently been stabilized/vegetated since completion of construction of the dunnage storage structure. The roof drainage from the dunnage storage structure is discharged to the ground and then drains through the outfall OF-1 stormwater system. The roof drainage from the remaining southern portion of the building is not routed through outfall OF-1. During construction of additions to the facility in late 2013 and early 2014, a stormwater detention pond was constructed in the northern portion of the site. The detention pond is equipped with a forebay to capture sediment. The operation of this detention pond will aid in water quality parameters of water discharging to outfall OF-4. The pond will be maintained and inspected to continue proper operation. 4 Continental Automotive Systems - Stormwater Discharge Sampling for April 2014 May 16, 2014 1 AMEC Project 6252-14-0123 AMEC will continue to monitor rainfall conditions and plans to sample outfall OF-1 during a measureable storm event in May 2014. AMEC also recommends collecting a sample from sub -drainage basin OF-1 C, from a sampling point upgradient of OF-1 C in the eastern section of the loading dock, and from the dunnage storage structure roof discharge for analysis of zinc and copper. In addition, we recommend collecting a sample of rainfall at the site (direct collection of a rainfall sample in a decontaminated stainless steel bowl in the northern portion of site) for analysis of zinc and copper. The purpose of the proposed additional sub -drainage basin and direct rainfall sampling is to investigate potential sources of zinc and copper in the southern portion of the facility. AMEC recommends submitting this documentation of sampling and the attached Semi- annual Stormwater Discharge Monitoring Report to NCDENR for their files. In anticipation of potential benchmark exceedances at outfall OF-1 for the next monthly sampling event, AMEC recommends contacting the NCDENR Asheville Regional Office industrial stormwater designee for Henderson County to discuss the results of the recent Tier Two response sampling, the results of the 'investigative' sampling, and tentative future 2014 sampling activities. We appreciate the opportunity to provide water resource services on this project.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike dupiicate anaiysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier i❑ Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure durinq the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting Limit in the method blank are qua iified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. Tne percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyze is outside the control limits for the laboratory control samn'_e or any other control sample, the parameter is flagged with a "J4" qualifies for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analyzes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected' for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative. percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, diuestion or extraction process, and analysis. Concentrations of target analytes above the reporting li:ait in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extractiOn and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits. for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target anaLytes. The percent recovery of the target analytes also has statistical control limits. if any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative aercent.difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier. page 5 of 5 March 25, 2014 Siffins Information: Analysis Container Preservative chain of custody Page OESC -1 AMEC Asheville, NC Project Manager TIM 1k. 1308-C Patton Avenue 1308-C Patton Avenue Asheville, NC 28806 Asheville, NC 28806 J L, A. a C• I I- N C U S Report to: Rodney Clark I Email To- rodney.clarkipwarnec.ccm A I MISS Lebanan Rd M4■ Pho"k: :1-118 SIV,1,9 Phone: Fax 615-7.SS-59 Project City/State A 69 Descriptiom Continental Automotive Collected: J 1 AN twr WN IV; IN, Fti P., I, a . 21 Phone: 828-252-8130 Pay: 828-251-9690 Client Project R —)4 6 k2_3 C2_5Z tab Pro;ect 4 LAWENGAN-6686081787 Collected by (print); Ccllected;,bw {signature): Site ID # P.O. ti 0 12_�3 0 30,15 Date Resillts Needer!

Continental-8 -1- Mr. Bradley Bennett Stormwater Permitting Unit Division of Water Quality 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Date Reference April 23, 2014 General Permit Number: NCG030000 Dear Mr. Bennett, Continental Henderson Plant One Quality Way Fletcher, North Carolina 28732 APR. g1914 Please find attached a copy of our lab analysis as well as our signed report for Stormwater Sampling for the March 2014 period. The attached results from our facility located at 1 Quality Way, Fletcher, North Carolina 28732 were obtained to comply with General Permit number NCG030000 effective November 1, 2012 through October 31, 2017. Our facility is conducting representative outfall sampling as approved by your office. Stormwater sampling was conducted by AMEC personnel on March 16, 2014 between 7:00am and 5:00am March 17, 2014. The total rainfall for the event was 0.52 inches as measured by the Asheville Regional Airport gauging system which is located approximately one mile northeast of our campus. Rainfall of greater than 0.02 inches was not recorded during the 72 hour period prior to this representative storm event. Continental Henderson received the lab report from ESC Lab Sciences defining the lab analysis of our samples collected during the significant rainfall event. These results indicate that Outfall 1 indicates Zinc levels and Copper Levels exceed the benchmark value in this and the previous sampling period. All other elements are within permit levels. These measurements in excess of the benchmark levels have triggered a Tier Two response for OF-1. Indicated below are the steps taken to correct the exceedence in the sampled outfall. Tier Two OF-1: 1. An inspection of the outfall area was completed at March 31, 2014 and April 21, 2014. Neither inspection showed the presence of solids or heavy metals in the area. The process in the Plating areas as well as the roof areas were also reviewed with no findings. 2. Inspections will continue to occur on a bi-weekly basis until the next rainfall event to observe the outfall and note any changes to the conditions. If conditions do not deteriorate the inspections will return to the required monthly inspection plan. 3. Basic cleaning of the outfalls by our Facilities team will be completed within 30 days and any necessary modifications to prevent erosion and sediment control will be implemented. 4. We have recorded the instance in our Site Stormwater Plan as well as our site Corrective and Preventative Action Plan and will track the corrective actions to closure. 5. The results were discussed in the quarterly IS014001 Program Management Review in April. 6. Inspections will continue to occur on a bi-weekly basis until the next rainfall event to observe the outfall and note any changes to the conditions. If conditions do not deteriorate the inspections will return to the required monthly inspection plan. 7. Stack testing for the units for Plating were completed for metal emissions and Zinc was not found in levels to indicate a source for the contaminate in the outfall in late 2013. They have been conducted again in March 2014 but the results have not been received from the laboratory. 8. Inquiries of the suppliers for the Scrubber units in our Plating process has been completed. Our primary focus was operation of the unit, verification of preventative maintenance actions, and verification of the robustness of the system. 9. Monthly sampling will continue to occur for the outfall. ConfinentalA _2_ It is our belief these actions will identify the sources of our discharge overages and the facility will return to operating within the boundaries of our permit parameters. We appreciate any feedback you may have relative to our report and actions. Please do not hesitate to contact me or Lisa Foster -Morrow with any questions you might have regarding our submittal.
