Fisher, Owner 600 Mountain Avenue Murray Hill, New Jersey 07974 Dear Mr. Fisher: NORTH CAROLINA EnvironmentalQuaAty January 2, 2019 Subject: Final NPDES Permit Renewal Permit NCO080853 Salem Business Park Remediation Site Forsyth County Grade I PCWPCS SIC Code 3661 Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). Please note that the receiving stream is listed as impaired for benthos on the North Carolina 2016 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. In response to comments received from AECOM on behalf of Nokia of America Corporation on November 28, 2018, the following changes were made to the draft permit sent to you on October 31, 2018: • A component description revision was made which adds language to indicate that the granular activated carbon (GAC) is used as a back-up at the facility. • The description of the receiving waters has been adjusted from "Salem Creek" to "unnamed tributary to Salem Creek." • 1,4-Dioxane monitoring — A typographical error was made in the description of the 1,4- dioxane monitoring requirement in the draft cover letter, citing annual monitoring instead of quarterly monitoring. The language has been revised to reflect the permit requirement: As 1,4-dioxane is considered a parameter of concern and the facility is near Water Supply waters, quarterly monitoring for 1,4-dioxane and Special Condition A.(4.) 1,4-Dioxane Monitoring and Limits Reopener have been added to the permit.

Instream monitoring may be conducted by the Permittee, and there are also Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in which case instream monitoring is waived in the permit as long as coalition membership is maintained). If applicable, summarize any instream data and what instream monitoring will be proposed for this permit action: Instream monitoring is not required in the permit. Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): NO Name of Monitoring Coalition: NA 5. Compliance Summary Summarize the compliance record with permit effluent limits (past 5 years): The facility reported no limit violations from June 2013 to June 2018. Summarize the compliance record with aquatic toxicity test limits and any second species test results (past 5 years): The facility passed 18 of 18 quarterly chronic toxicity tests from March 2014 to June 2018. Summarize the results from the most recent compliance inspection: The last facility inspection conducted in February 2016 reported that the facility was in compliance. 6. Water Quality -Based Effluent Limitations (WQBELs) Dilution and MixingZones ones In accordance with 15A NCAC 213.0206, the following streamflows are used for dilution considerations for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HID. If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): N/A If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): N/A Oxygen -Consuming Waste Limitations Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits (e.g., BOD= 30 mg/l for Municipals) may be appropriate if deemed more stringent based on dilution and model results. Ifpermit limits are more stringent than TBELs, describe how limits were developed: N/A Page 3 of 8 Ammonia and Total Residual Chlorine Limitations Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of 1.0 mg/l (summer) and 1.8 mg/l (winter). Acute ammonia limits are derived from chronic criteria, utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals. Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection of aquatic life (17 ug/1) and capped at 28 ug/1(acute impacts). Due to analytical issues, all TRC values reported below 50 ug/1 are considered compliant with their permit limit. Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: N/A Reasonable Potential Analysis (RPA) for Toxicants If applicable, conduct RPA analysis and complete information below The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero background; 3) use of 1/z detection limit for "less than" values; and 4) streamflows used for dilution consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of dissolved metals criteria in the RPA process in accordance with guidance titled NPDESImplementation of Instream Dissolved Metals Standards, dated June 10, 2016. A reasonable potential analysis was conducted on effluent toxicant data collected between March 2014 and March 2018. Pollutants of concern included toxicants with positive detections and associated water quality standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit: • Effluent Limit with Monitoring. The following parameters will receive a water quality -based effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water quality standards/criteria: Tetrachloroethene • Monitoring Only. The following parameters will receive a monitor -only requirement since they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but the maximum predicted concentration was >50% of the allowable concentration: NA • No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria and the maximum predicted concentration was <50% of the allowable concentration: Trichloroethene • POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for additional pollutants of concern. o The following parameter(s) will receive a water quality -based effluent limit (WQBEL) with monitoring, since as part of a limited data set, two samples exceeded the allowable discharge concentration: NA o The following parameter(s) will receive a monitor -only requirement, since as part of a limited data set, one sample exceeded the allowable discharge concentration: NA Page 4 of 8 If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program. Toxicitv Testine Limitations Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than domestic waste) will contain appropriate WET limits and monitoring requirements, with several exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test failure. Describe proposed toxicity test requirement: This is a Minor Industrial facility, and a chronic WET limit at 90% effluent will continue on a quarterly frequency. Mercury Statewide TMDL Evaluation There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and industrial facilities with known mercury discharges. Given the small contribution of mercury from point sources (-2% of total load), the TMDL emphasizes mercury *minimization plans (MMPs) for point source control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/1) will receive an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed the WQBEL value (based on the NC WQS of 12 ng(1) and/or if any individual value exceeds a TBEL value of 47 ng/l. Describe proposed permit actions based on mercury evaluation: The facility is not known to discharge mercury. Other TMDL/Nutrient Management Strateev Considerations If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within this permit: N/A Other WOBEL Considerations If applicable, describe any other parameters of concern evaluated for WQBELs: Per a 2005 email exchange between the Permittee and the Division, there is reason to believe 1,4-Dioxane is in the groundwater treated at the facility. The value discussed in 2005 is far below the NC protective value of 80 ug/L for class C waters. However, the facility is approximately 13 miles from the Yadkin River, which is designated as WS-IV waters. Water supply waters have an NC protective value of 0.35 ug/L for 1,4- Dioxane. The attached preliminary calculations indicate, based on the 2005 value of 8.2 ug/L, 1,4- Dioxane presence is not likely to negatively affect downstream waters. However, to better understand the level of concern for this contaminant in the facility's discharge, quarterly monitoring of 1,4-Dioxane coinciding with chronic toxicity monitoring has been added to the permit. Monitoring for 1,4-Dioxane shall be conducted using EPA Method 624.1. During the next renewal, the parameter may be removed if no reasonable potential to exceed water quality standards is shown. Page 5 of 8 If applicable, describe any special actions (HQW or OR99 this receiving stream and classification shall comply with in order to protect the designated waterbody: NA If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A NCAC2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: A 2-year compliance schedule is proposed for meeting the new tetrachloroethene effluent limit. Annual milestones are included for this Special Condition. If applicable, describe any water quality standards variances proposed in accordance with NCGS 143- 215.3(e) and 15A NCAC 2B.0226for this permit renewal: NA 7. Technology -Based Effluent Limitations (TBELs) Industrials (if not awlicable, delete and skip to next Section) Describe what this facilityproduces: The facility is a groundwater remediation facility. List the federal effluent limitations guideline (ELG) for this facility: The facility is not subject to any federal ELGs. If the ELG is based on production or f ow, document how the average production/f ow value was calculated. NA For ELG limits, document the calculations used to develop TBEL limits: NA If any limits are based on best professional judgement (BPJ), describe development: NA Document any TBELs that are more stringent than WQBELs: NA Document any TBELs that are less stringent than previous permit: NA 7. Antidegradation Review (New/Expanding Discharge): The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not degrade water quality. Permitting actions for new or expanding discharges require an antidegradation review in accordance with 15A NCAC 213.0201. Each applicant for a new/expanding NPDES permit must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105(c)(2). In all cases, existing instream water uses and the level of water quality necessary to protect the existing use is maintained and protected. If applicable, describe the results of the antidegradation review, including the Engineering Alternatives Analysis (EAA) and any water quality modeling results: NA 8. Antibacksliding Review: Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL limits, or WQBELs may be less stringent based on updated RPA or dilution). Are any effluent limitations less stringent than previous permit (YES/NO): NO If YES, confirm that antibackslidingprovisions are not violated: NA Page 6 of 8 9. Monitoring Requirements Monitoring frequencies for NPDES permitting are established in accordance with the following regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2) NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance, Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti - backsliding prohibitions would not be triggered by reductions in monitoring frequencies. For instream monitoring, refer to Section 4. 10. Electronic Reporting Requirements The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports (DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to submit additional NPDES reports electronically. This permit contains the requirements for electronic reporting, consistent with Federal requirements. 11.Summary of Proposed Permitting Actions: Table 2.

Public Notice Schedule: Permit to Public Notice: 10/31/2018 Per 15A NCAC 211.0109 & .0111, The Division will receive comments for a period of 30 days following the publication date of the public notice. Any request for a public hearing shall be submitted to the Director within the 30 days comment period indicating the interest of the party filing such request and the reasons why a hearing is wan -anted. 13. Fact Sheet Addendum (if applicable): The following comments were received from AECOM on behalf of Nokia of America Corporation on November 28, 2019: Comment: "Alcatel Lucent USA Inc." and "Alcatel -Lucent' should be replaced by "Nokia of America Corporation" throughout the permit due to a corporate merger that occurred on January 1, 2018. Response: The final permit has been altered to reflect the ownership change. Comment: The list of treatment system components should be updated to remove Granular Activated Carbon (GAC). Response: As the facility employs its GAC as a back-up, the component will remain listed. Indication of the component being a back-up has been added to the description. Comment: No schedule is provided for annual effluent monitoring of 1,4-dioxane, which is a new monitoring requirement. AECOM proposes to conduct this monitoring in March of each year. Response: Monitoring for 1,4-dioxane shall be conducted quarterly. Reference to annual monitoring in the draft cover letter was a typographical error and should be disregarded. Comment: As the 61 tetrachloroethene (PCE) data point in the RPA is a pH value, please remove it for the final RPA calculation. The result does not affect the outcome of RPA analysis. Response: The 61 data point has been omitted in the final calculation. Were there any changes made since the Draft Permit was public noticed (Yes/No): YES If Yes, list changes and their basis below: • A component description revision was made which adds language to indicate that the granular activated carbon (GAC) is used as a back-up at the facility. • As the facility discharges to an unnamed tributary to Salem Creek, the description of the receiving waters has been adjusted from "Salem Creek" to `unnamed tributary to Salem Creek." 14.

Comment #1— Permit Cover Sheet (page 1 of 8) "Alcatel -Lucent USA Inc." and "Alcatel -Lucent" should be replaced with "Nokia of America Corporation" throughout the permit due to a corporate merger that occurred on January 1, 2018. Comment #2 — Supplement to Permit Cover Sheet (page 2 of 8) The list of treatment system components should be updated to remove Granular Activated Carbon (GAC). In April 2017, AECOM discovered a leak in the bottom of the GAC tank and shut -down the GWTS. AECOM notified the North Carolina Division of Water Resources (DWR) of the problerh in a letter dated May 4, 2017. The letter stated that Nokia was considering eliminating the GAC since the air stripper is capable of treating water to below permit limits and the GAC did not provide further significant reductions of PCE. The letter also inquired about whether a permit modification would be required to eliminate the GAC. AECOM was advised by DWR that no permit modification was required. The GWTS resumed operating in May 2017 without the GAC unit. A new GAC unit was installed in August 2017, which currently serves as a back-up unit that can be used when higher than normal VOC concentrations are anticipated. Comment #3 — Condition A. (1.) — Annual Monitoring Requirement for 1,4-Dioxane (page 3 of 8) No schedule is provided for annual effluent monitoring of 1,4-dioxane, which is a new monitoring requirement. AECOM proposes to conduct this monitoring in March of each year. Comment #4 — Reasonable Potential Analysis Calculations The 'data' sheet in the Reasonable Potential Analysis (RPA) calculation workbook contains a data entry AECOM error. Datapoint #6 for tetrachloroethene (PCE), dated April 27, 2015, is a pH value. PCE was not analyzed in April 2015, so this data point should be removed from the data set. This results in a lower maximum predicted effluent concentration, but does not change the calculated PCE discharge limit because the maximum predicted effluent concentration (7.5 micrograms per liter [µg/L]) is still greater than the allowable effluent concentration (6.12 µg/L).

Re: [EXTERNAL] streamflow statistics Ms. Stewart, In response to your inquiry about the low -flow characteristics (7Q10, 30Q2, W7Q10, 7Q2) for an unnamed tributary to Salem Creek at Winston Salem in central Forsyth County, the following information is provided: A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not indicate previous low - flow determinations for the ]at/long coordinates (36.055208 //-80.230861) provided via your email dated November 14, 2018. However, the low -flow files do indicate previous low -flow determinations at nearby locations within this Salem Creek tributary basin, based on transfer of flow characteristics from nearby index sites. No USGS discharge records are known to exist for the point of interest In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -flow characteristics at ungaged locations are determined by assessing a range in the low -flow yields (expressed as flow per square mile drainage area, or cfsm) at nearby sites where estimates have previously been determined. A basin delineation completed using the online USGS StreamStats application for North Carolina (http://water.usgs.gov/osw/streamstats/north carolina.html) indicates the drainage area for the point of interest (36.05519, - 80.23081 NAD83) is about 0.05 sgmi. For streams in Forsyth County, low -flow characteristics published by the USGS are provided in two reports (1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at http://pubs.usgs.gov/wsp/2403/report.Ddf. The report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites with drainage basins between 1 and 400 sgmi and not considered or known to be affected by regulation and/or diversions. (2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low -flow characteristics and flow -duration statistics for selected USGS continuous -record streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at http://Pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic years discharge records were available for flow analyses. Inspection of the two reports indicates the presence of eight nearby selected USGS partial -record sites (6) and continuous -record streamgages (2) in general vicinity of the point of interest where low -flow characteristics were published. Among these 8 sites, the low -flow discharge yields for the indicated flow statistics are as follows: Annual 7Q10 low -flow yields ==> from 0.08 to 0.28 cfsm (average about 0.15 cfsm, median about 0.14 cfsm) Annual 30Q2 low -flow yields =_> from 0.2 to 0.51 cfsm (both average and median about 0.33 cfsm) Winter 7Q30 low -flow yields =_> from 0.16 to 0.38 cfsm (average about 0.27 cfsm, median about 0.28 cfsm) Annual 7Q2 low -flow yields ==> from 0.16 to 0.42 cfsm (both average and median about 0.26 cfsm) Average annual discharge yields ==> from 0.9 to 1.24 cfsm (average about 1.03 cfsm, median about 1 cfsm) Application of the above range in yields to the drainage area (0.05 sgmi) for the point of interest results in the following estimated low -flow discharges: Annual 7Q10 discharges =_> from 0 to 0.01 cfs (both average and median about 0.01 cfs, rounded down to zero flow) Annual 30Q2 discharges =_> from 0.01 to about 0.03 cfs (both average and median about 0.02 cfs) Winter 7Q10 discharges =_> from about 0.01 to 0.02 cfs (both average and median about 0.01 cfs, rounded down to zero flow) Annual 7Q2 discharges ==> from about 0.01 to 0.02 cfs (both average and median about 0.01 cfs, rounded down to zero flow) Average annual discharge ==> from 0.05 to 0.06 cfs (both average and median about 0.05 cfs) Notes: (1) The extremely low magnitudes of the above estimated low -flow characteristics reflect the very small drainage area for the point of interest. (2) The USGS does not provide estimates of the IQ10 discharge within the scope of standard responses to low -flow requests. However, because the estimated 7Q10 discharge is zero flow, the estimated 1Q10 discharge mathematically defaults to zero flow. (3) Please note that because your site is located in the vicinity of downtown Winston-Salem, it should be acknowledged the effects of development on low -flow characteristics in urban basins have not been formally studied by the USGS for North Carolina. There has been discussion within the hydrologic community that development may reduce low -flow characteristics because increases in impervious areas reduce the available surface area where infiltration of runoff can occur, thereby reducing the available base flow to streams during extended dry periods.

The max groundwater concentration that you reported for 1,4-dioxane of 8.2 ug/l is well below our human health criteria of 300 ug/l for C class waters, thus we would not consider this a pollutant of concern for an NPDES discharge. It looks like the NC 2L groundwater standard of 7 ug/l groundwater standard will present the greater environmental concern. I would recommend that you include any analytical results for 1,4-dioxane with your next NPDES permit renewal in 2009.

At the request of Mr. Billy Meyer, the NCDENR-HWS Case Manager for this site, ENSR Consulting and Engineering (NC), Inc. (ENSR) sampled the following wells and submitted those samples for laboratory analysis to detect the presence of 1,4-Dioxane: extraction wells VOC-1 and EW-15, and monitoring wells: C-2, MW-2A, C-5, and MW-18A. The sampling event was conducted on June 13, 2005, and the results were reviewed to determine whether 1,4-Dioxane is present in groundwater at concentrations above the NC 2L standard of 7 micrograms/liter. The results of the laboratory analysis of the groundwater samples were provided in a report submitted to Billy Meyer on July 18, 2005. 1,4-Dioxane was not detected in two of the monitoring wells, C-2, C-5, nor was it detected in extraction well VOC-1. Detection limits were 3.3 mg/I - micrograms/liter for analyses performed on each of these samples. 1,4-Dioxane concentrations were recorded in groundwater samples collected from extraction well EW-15 (8.2 mg/L - micrograms/titer) and monitoring wells MW-18A (6.2 mg/L-micrograms/liter), and MW-2A (5.1 mg/L-micrograms/liter).

Department of Environmental Quality Division of Water Resources, Water Quality Permitting 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Subject: Proposed Compliance Schedule Salem Business Park Remediation Site #NC0080853 Nokia of America Corporation 3370 Lexington Road, Winston-Salem, Forsyth County, North Carolina Dear Mr. Coco On behalf of Nokia of America Corporation (Nokia), AECOM Technical Services of North Carolina Inc. (AECOM) is submitting the following Compliance Schedule for approval to ensure compliance with the proposed tetrachloroethene (PCE) limits specified in National Pollutant Discharge Elimination System (NPDES) Permit #NC0080853 for the groundwater treatment system located at the former Nokia facility, now known as the Salem Business Park Remediation Site, in Winston- Salem, Forsyth County, North Carolina. Background A groundwater treatment system (GWTS) currently operates at the Site to remediate groundwater impacted with volatile organic compounds (VOCs). The primary treatment unit of the GTWS is a six - tray air stripper unit designed for up to 120 gallons per minute (gpm) of groundwater flow and 600 standard cubic feet per minute (scfm) of air flow through the unit. The air stripper was designed to reduce concentrations of PCE in groundwater to below the laboratory detection limit. As part of the NPDES permit monitoring requirements, AECOM collects quarterly system effluent samples from a flume (FE-151) located approximately 100 feet downstream of the air stripper. In addition to these quarterly samples, AECOM collects monthly air stripper influent and effluent samples to evaluate the system effectiveness at removing VOCs. Since 2015, the PCE concentration in quarterly system effluent samples collected from flume FE-151 has ranged from <0.5 micrograms per liter (pg/L) to 5.6 pg/L, with an average concentration of 2.4 pg/L. During the same time period, the PCE concentration in monthly air stripper effluent samples has ranged from <0.5 pg/L to 8.8 pg/L, with an average concentration of 2.6 pg/L. On August 29, 2018, AECOM received notification from the North Carolina Division of Water Resources (DW R) that the facility would be receiving a new NPDES permit that would include a PCE discharge limit of 6.1 pg/L, which is significantly lower than the previous limit of 17 Ng/L. While the system effluent FE-151 has not exceeded this proposed limit, the PCE concentrations have been very close to the proposed limit. Based on the expectation that the air stripper unit is capable of reducing PCE concentrations to below the laboratory detection limit, AECOM proposes the following actions to evaluate and improve the air stripper's performance to ensure consistent compliance with the new PCE discharge limit. AECOM Compliance Schedule The plan to ensure consistent compliance with the new PCE discharge limit will be conducted in a tiered approach. Tier 2 will only proceed if the actions in Tier 1 do not improve system performance or provide sufficient evidence to confidently assume effluent concentrations will remain below the PCE discharge limit. Tier 1 — October 2018 through October 2019 ! 117 V 5 ri t t ti • Upgrade Air Stripper Flow Instrumentation October 2018) The air stripper does not currently have instrumentation to precisely measure the volumetric -air _ or groundwater M5o roi uF gl—tFe system. uTlow is -currently estimated using tie air injectio pressure and blower flow curve, and groundwater flow is estimated from the air stripper sump discharge flow rate. To improve these measurements, AECOM proposes to install an influent groundwater flow meter and an in -line differential pressure gage to measure volumetric air flow. These instruments will allow for accurate and precise measurements of air and water flow through the air stripper during operation. Air to Water Ratio Testing (October 2018-March 2019) Following the installation of upgraded flow measurement instrumentation, monthly adjustments will be made to the volumetric air flow to test the impact of various air -to -water volumetric flow ratios on system performance. Higher air -to -water ratios typically increase volatilization of VOCs and increase system efficiency. However, air -to -water ratios can be set too high and result in groundwater flooding across trays, resulting in uncontrolled and inadequately treated groundwater flow through the system. Monthly air Stripper influent and effluent VOC samples will be collected to evaluate the impact of air -to -water ratio changes on PCE removal efficiency. Monitor Optimal Air to Water Ratio (April 2019-October 2019) After a review of the air -to -water ratio testing results, the ratio with the highest PCE removal rate will be selected for continuous operation. Monthly air stripper influent and effluent samples will be collected to evaluate the performance of the air stripper over a six month period while operating at the selected ratio. This will determine if adjustments to the air -to -water ratio in the air stripper will be sufficient to consistently maintain PCE concentrations below the new discharge limit. Evaluate Sample QA/QC (January 2019-June 2019) Duplicate air stripper influent and effluent samples will be collected for six months as part of an effort to evaluate laboratory analytical precision. Air stripper effluent PCE concentrations are typically between 1 and 5 pg/L, a difference of four parts per billion. The collection of duplicate samplesGvill evaluate the reproducibility of PCE concentration results and determine if month - to -month variability in effluent concentrations is a result of changes to air stripper operation, or at least in part due to laboratory precision. n �� Tier 2 — November 2019 through November 2020 �1T Evaluate Air Stripper Tray Performance (November 2019) The higher than expected effluent PCE concentrations could be a result of inadequate h C treatment of groundwater on one or more air stripper trays. AECOM proposes installing sample ports on each of the six trays of the air stripper to collect groundwater samples. These samples will be abed to evaluate PCE removal efficiency on each tray and could identify -trays that are not achieving optimal performance. • Evaluation Follow-up (fjanuary 2019-March 2019) Based on the results of the air stripper tray performance testing, AECOM will conduct one of two follow-up steps: AECOM 1. If the air stripper tray performance evaluation results clearly indicate one or more trays are ineffective in reducing PCE concentrations, system modifications targeting specific trays will be made to improve the air stripper PCE removal efficiency. If the air stripper tray performance evaluation results do not clearly identify specific trays that require modification, AECOM will evaluate other potential options for reducing effluent PCE concentrations. AECOM may request an extension to the compliance schedule to allow for 91 further testing and evaluation. SI 4,,* 1 r n ...- 144 Monitor Modified System Performance (April 2019 - November 2020) _ Following system modifications, monthly air stripper influent and effluent samples will be collected through November 2020 to evaluate the effectiveness of system modifications.

Department of Environment and Natural Resources Division of Water Resources, NPDES Unit 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Subject: Request for Renewal of NPDES Permit NCO080853 Salem Business Park Remediation Site Alcatel -Lucent USA Inc. 3370 Lexington Road, Winston-Salem, Forsyth County, North Carolina Dear Ms. Thedford: On behalf of Alcatel -Lucent USA Inc., AECOM North Carolina Inc. (AECOM) is requesting renewal of National Pollutant Discharge Elimination System (NPDES) Permit NCO080853 for the groundwater treatment system located at the former Alcatel -Lucent facility, now known as the Salem Business Park Remediation Site, in Winston-Salem, Forsyth County, North Carolina. The completed application is enclosed as Attachment 1. Recent Changes to Facility Since the last issuance of the NPDES permit, the groundwater treatment system was replaced and a minor permit modification was issued November 12, 2012. There were no changes to the contaminants the system is treating, the basic treatment technology, permit effluent limits, or permitted outflow location. The prior NPDES permit (dated June 12, 2009) specified that the remediation system consists of the following components: • Extraction wells • Oil/water separator • Granular media filtration • Feed -water storage and equalization • Parallel filtration and air -stripping treatment trains receiving segregated flow • Activated carbon • Solids removal (filter press) AECOM The early 1990s design of the original remediation system was based on using parallel treatment systems for different contaminant types, with System A receiving flow from diesel fuel extraction wells and perimeter volatile organic compound (VOC) extraction wells, and System B receiving flow from interior VOC extraction wells. Twenty years of system data indicate that contaminant concentrations and flow rates are significantly lower than anticipated during the original remediation system design. As a result, a new single -stream remediation system was designed and installed to treat the extracted groundwater. The new system consists of the following components: • Extraction wells • Feed -water equalization • Bag filtration • Low profile air stripper • Granular activated carbon The system component list on the "Supplement to Permit Cover Sheet" portion of the NPDES permit was modified in the November 12, 2012 minor permit modification to reflect the new components listed above (Attachment 2). In addition to the minor changes described above, AECOM also began using oxidizing biocides (sodium hypochlorite and hydrogen peroxide) and a biodispersant (Redux-620) to prevent biological fouling of treatment system unit processes and piping. The biocide and biodispersant application and associated approval for use from the Division of Water Quality are included as Attachments 3 and 4, respectively. Authorized Representative Attached is the previous signature authority letter from Alcatel -Lucent dated November 25, 2008, delegating signature authority for NPDES correspondence to the ENSR Project Manager (Attachment 5). ENSR was purchased by AECOM, so an updated letter is also included in this submittal delegating signature authority to the AECOM project manager. Sludge Management This facility is a groundwater remediation system and does not have a Sludge Management Plan; however, a small volume of solids (spent bag filters) are generated and managed as hazardous waste. Two parallel bag filters provide particulate filtration and require changing approximately once per week. Spent bag filters are placed in a labeled, covered 55 gallon drum. To date, less than one drum of spent bag filters has been generated. Once a full drum accumulates, the drum will be sealed and moved from the Satellite Accumulation Area to the Temporary Storage Area. Within 90 days of being moved to the Temporary Storage Area the drummed spent bag filters will be picked up, transported and disposed of as hazardous waste. Annual generation of spent bag filters is expected to be approximately one to two drums, or 500 to 1,000 pounds.

Department of Environment and Natural Resources Division of Water Quality, Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Subject: Proposed Biocide and Biodispersant Application at Salem Business Park Remediation Site, Discharge #NC0080853 Dear Ms. Moore: AECOM North Carolina, Inc. (AECOM) currently operates and maintains a groundwater remediation system on behalf of Alcatel -Lucent USA, Inc. (Alcatel -Lucent) at the Former North Carolina Works — Lexington Road Plant in accordance with Resource Conservation and Recovery Act permit NCD 003 213 907. The groundwater remediation system uses a combination of air stripping and granular activated carbon (GAC) to treat volatile organic compounds in extracted groundwater prior to discharging to an unnamed tributary of Salem Creek under National Pollutant Discharge Elimination System (NPDES) Permit #NC0080853. To prevent biological fouling of treatment system unit processes and piping, AECOM requests permission to apply the following oxidizing biocides to above -ground treatment unit processes and piping: • Sodium hypochlorite • Hydrogen peroxide AECOM also requests permission to apply the following biodispersant to above -ground treatment unit process and piping for the same reason: • Redux-620 Enclosures provided with this letter include materials safety data sheets (MSDS) for a typical high strength sodium hypochlorite and typical hydrogen peroxide product, the manufacturer's MSDS and fate -and -transport statement for Redux-620, and the Aquatic Toxicology Unit's biocide application worksheet and spreadsheet. It is anticipated that complete or nearly complete reduction of applied oxidizing biocides will occur within the GAC unit process prior to discharge. It is also expected that catalytic hydrolysis of the iron dispersant within Redux-620 (tetrakis hydroxymethyl phosphonium sulfate, or THPS) to occur within the GAC unit process. Therefore, AECOM has completed the enclosed spreadsheet and worksheet as a calculation of the maximum discharge concentration of sodium hypochlorite, hydrogen peroxide, and Redux-620 product that may be discharged to the NPDES outfall assuming decomposition or adsorption with the GAC unit process, no 7Q10 flow, and negligible product decay. AECOM proposes to monitor the GAC unit process effluent using field test kits for free and residual chlorine, for peroxide, and for THPS in order to maintain discharge concentrations below that which would result in the dosage rate specified on the enclosed spreadsheet and worksheet. AECOM Monitoring of the active ingredients hypochlorite, peroxide, and THPS is proposed as a real-time method for estimating the amount of applied whole product that is discharged to the NPDES outfall. The proposed action levels are: • Sodium hypochlorite: 1 milligram per liter (mg/L) as OCI- • Hydrogen peroxide: 0.35 mg/L H2O2 • Red ux-620: 10 mg/L as TH PS The proposed action levels correspond to the concentrations used to calculate the dosage rate on the enclosed biocide application spreadsheet and worksheet. At the proposed action levels, discharge of the measured components of strong bleach, hydrogen peroxide, and Redux-620 can be sustained for up to 1 minute, 5 minutes, and 60 minutes, respectively, without exceeding or potentially exceeding the whole -product mass discharge limits as defined by the enclosed worksheets and spreadsheet. Real-time monitoring is therefore proposed at a frequency of one half the maximum sustained discharge time at the action level concentration, or every 30 seconds during sodium hypochlorite application, every 2.5 minutes during hydrogen peroxide application, and every 30 minutes during Redux-620 application. Testing will be conducted at the onset of the application period, throughout the application period and for 20 minutes following the application period, which is approximately enough time for 1,000 gallons to be conducted through the treatment unit processes at an influent flow rate equivalent to the current system throughput (0.075 MGD). Discharge of effluent with concentrations of monitored constituents above the proposed action levels will be discontinued immediately if monitoring indicates that action levels are exceeded. Application of the proposed biocides or biodispersant is proposed daily for one week each and on an as -needed basis thereafter. The testing rigor outlined in this letter is proposed as an initial assessment. One-time spot checking is proposed for subsequent, as -needed applications that may follow the initial treatment if complete treatment of the monitored constituents can be demonstrated by the initial assessment.

These products will be discharged into their Outfall 001 and in to an unnamed tributary of Salem Creek. Calculations predict the use of these products, at the stated dosage rates, will not cause toxic impacts to aquatic life in the receiving stream, unnamed tributary of Salem Creek. Therefore, the use of these products as an additive to their cooling water system at Salem Business Park Remediation Site is acceptable. cc: Tom Belnick, Western NPDES Program Central Files Environmental Sciences Section 1621 Mail Service Center, Raleigh, North Carolina 27699-1621 Location: 4401 Reedy Creek Road, Raleigh, North Carolina 27607 Phone: 919-743-84001 FAX: 919-743-8517 Internet: http://aortal.ncdenr.ora/webtwaless/home NoChCarolina Nhu&Ilff An Equal Opportunity 1 Affirmative Action Employer Dishcharger Name BIOCIDE WORKSHEET PERMIT#: NCO080853 RECEIVING STREAM: unnamed tributary of Salem Creek (Middle Fork Muddy Creek) 7Q10 (cfs): 0.00 I.W.C.%: 100.00 PRODUCT: Redux 620 ACTIVE INGREDIENT: Aqueous solutions of acrylate copolymer (6%), proprietary organic phosphorous compound (6%), and proprietary sulfonated phosphonium salt (10%) HALF LIFE (DAYS): 1000.00 STEADY STATE DISC CON(4.1604 LC50/EC50 OF SELECTED TOX DATA (MG 700 DEGRADATION FACTOR: 75.000 DECAY RATE: 0.0000 APPLICATION FACTOR: 0.010 DOSAGE RATE (GRAMS/DAY): 1181.0448 AVG DAILY DISCHARGE (MGD): 0.075 INSTREAM BIOCIDE CONC:4.1604 VOLUME OF SYSTEM (MIL.
