(Mid -Atlantic) has prepared this Limited Phase II Environmental Site Assessment Report for the property located at 810 Lufkin Road in Apex, Wake County, North Carolina (Drawing 1). This work was conducted based on the initial findings of a draft Phase 1 Environmental Site Assessment (PESA) dated January 29, 2013 and conducted by Withers & Ravanel, Inc. which identified recognized environmental conditions (RECs) associated with the historical use of the subject site as a commercial printing facility and industrial operations on adjacent properties. A subsequent Pre - Purchase Assessment dated May 21, 2013 and conducted by Mid -Atlantic details soil, groundwater and vapor intrusion testing activities performed at the subject site to address RECs identified in the draft Withers and Ravanel PESA. The Pre -Purchase Assessment concluded that groundwater contamination is present on the subject site and may be attributed to the groundwater contamination associated with the chlorinated solvent release on the north adjacent property (Apex Tools). This Limited Phase 11 Environmental Assessment Report was conducted to evaluate two objectives: • Provide a general assessment of vapor intrusion potential at the subject site based on sub -slab soil gas data; and • Collect groundwater and soil samples in an attempt to answer the question: Is there evidence to suggest that historic subject site activities have contributed to the chlorinated solvents detected in the groundwater near the northeast corner of the building? 2.0 SUMMARY OF SAMPLING ACTIVITIES 2.1 Sub -Slab Soil Gas Sampling Activities On January 15 and 16, 2015, Mid -Atlantic mobilized to the subject site to collect sub -slab soil gas samples. Seven locations were selected in the on -site building to provide a general assessment of vapor intrusion potential and were spaced evenly within the structure. Vapor pins were installed at these locations in the ground floor slab for use as a sampling port. The vapor pins are air tight barbed fittings used for collection of sub -slab soil gas samples. The soil gas samples were collected using stainless steel "Mini-SUMMA" canisters at a flow rate of 200 mL/min. For quality assurance purposes, leak checks were performed prior to sample collection using helium tracer gas, a shroud over the sample probe site, and a portable helium detector. Soil gas samples were submitted under chain -of -custody from the subject site to Con -Test Analytical Laboratory in East Longmeadow, Massachusetts for analysis by EPA Compendium Method TO-15. Indoor air data (temperature and relative humidity) was collected using a portable monitor at each sampling location. Sub -slab soil gas sample locations are shown on Drawing 3. 46 Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Wurst Property Apex, North Carolina 2.2 Soil Sampling Activities March 2, 2015 Page 2 On January 20, 2015, Mid -Atlantic mobilized to the site to oversee the advancement of four soil borings (VSB-1 through VSB-4). Soil boring services were provided by Quantex, Inc. of Raleigh, North Carolina, a North Carolina Certified Driller (NC Well Contractor Certification No. 3106A). Soil borings VSB-1, VSB-2, and VSB-3 were placed along the northeast exterior wall of the Wurst Building and soil boring VSB-4 was placed in the interior of the northeast portion of the Wurst building. These soil boring locations were selected to assess if documented groundwater contamination near the northeast portion of the subject site could be attributed to a potential release from the former machine shop or from other industrial activities performed in that area, including plating operations. Soil sample locations are shown on Drawing 4. Soil boring samples were collected from these locations using a GeoProbe "macrocore" sampling device and direct push technology (DPT). In general, the lithology at the site consisted of red to orange silty clay from land surface to a depth of approximately 8 feet below land surface (BLS), where we encountered probe refusal due to the presence of bedrock. Soil boring logs are provided in Appendix A. Soil samples were collected at depths of one foot BLS and eight feet BLS at all four soil boring locations. The samples were stored in laboratory -supplied containers, packed into an ice -filled cooler and transported under chain -of -custody from the subject site to Con - Test Analytical Laboratory in East Longmeadow, Massachusetts. The soil samples were analyzed for volatile organic compounds (VOCs) according to EPA Method 8260. 2.3 Groundwater Samolina Activities On January 19 through 23, 2015, Quantex, Inc., under Mid -Atlantic's supervision, constructed six permanent monitoring wells (in pairs MW-1, MW-1 D; MW-2, MW-2D; MW- 3, and MW-3D) near the northeast exterior portions of the Wurst Building. Each well was installed by first using 4" augers to auger refusal due to bedrock, which was between five feet and eight feet BLS at each well location. After auger refusal was encountered, Quantex, Inc. utilized air rotary drilling to install three shallow groundwater monitoring wells to a depth of 50 feet BLS, and three deep groundwater monitoring wells to a depth of 100 feet BLS which were paired with the 50-foot BLS wells. The three shallow monitoring wells were constructed using 2-inch diameter Schedule 40 PVC casing and the three deep monitoring wells were constructed using 4-inch diameter Schedule 40 PVC outer casing and 2-inch diameter Schedule 40 PVC inner casing (Appendix A). The monitoring wells were installed based on well construction data and groundwater data obtained from nearby groundwater monitoring wells. Monitoring well locations are shown on Drawing 5. Obvious signs of bedrock fractures or evidence of water bearing zones were not encountered during drilling of the shallow and deep monitoring wells. As Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Wurst Property Apex, North Carolina March 2, 2015 Page 3 such, groundwater was slow to accumulate in these wells. Mid -Atlantic surveyed the depth to water for two weeks before sampling the wells. Due to the slow groundwater recovery, wells MW-1 D, MW-2, MW-2D, and MD-3D could not be developed and purged per the standard installation and sampling procedures detailed in Appendix B. The samples sent to the laboratory were collected from the water accumulated in these wells without development or purging. Monitoring wells MW-1 and MW-3 were developed and purged according to field procedures prior to sampling. A sample could not to be retrieved from MW-2D because less than 1" of water was present in the well. Groundwater samples collected from MW-1, MW-1 D, MW-2, MW-3, and MW-31D were packed into an ice -filled cooler and transported under chain -of -custody from the subject site to Con -Test Analytical Laboratory in East Longmeadow, Massachusetts. Groundwater samples were analyzed for volatile organic compounds (VOCs) according to EPA Method 8260. 3.0 SUMMARY OF LABORATORY TEST RESULTS The laboratory analytical reports and chain -of -custody records for the samples collected at the site are provided in Appendix C. Among the seven sub -slab soil gas samples collected on January 15 and 16, 2015 and submitted for laboratory analysis by EPA Method To-15, trichloroethylene (TCE) was detected in one sample in a concentration that exceeds NCDENR Division of Waste Management (DWM) default non-residential screening levels (TCR=1.0E-05; HQ=0.2). No other target analytes were detected at concentrations that exceed the default screening levels. The sample sum target non -cancer hazard index of 1 (HI=1), and the target cancer risk (1.OE-05) was not exceeded among all sub -slab soil gas samples. Sub -slab soil gas results are summarized in Table 1. As summarized in Table 2, no target compounds were detected, using the specified laboratory test methods, in soil samples collected from the subject site. As summarized in Table 3, multiple chemical constituents were detected in groundwater samples collected from MW-1, MW-2, MW-3, and MW-3D. Constituents detected above North Carolina 15A NCAC 2L.0202 groundwater standards include 1,2-Dichlorobenzene, 1,1-Dichloroethane, 1,2-Dichloroethylene, cis- 1,2-Dichloroethylene, TCE, and Vinyl Chloride. Additionally, acetone was detected in MW-31D above North Carolina groundwater standards. Acetone can be a laboratory or field artifact and was detected in the laboratory method blank; therefore, acetone detected in MW-3D is likely not representative of water quality. 46 Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Wurst Property Apex, North Carolina 4.0 CONCLUSIONS March 2, 2015 Page 4 The assessment of sub -slab soil gas indicates that chlorinated solvents are present in the soil gas beneath the subject site building. Comparison of the sub -slab soil gas data collected at the subject site to the NCDENR DWM Non -Residential Vapor Intrusion Screening Levels shows that the detected concentrations do not exceed acceptable risk/hazard levels. We understand that the subject site has been determined eligible for a Brownfields Agreement with the NCDENR Brownfields Program (Program). As the Program evaluates this data, it may determine that additional assessment is required to better understand the potential for vapor intrusion at the subject site. In addition, since the source of the solvents in the soil gas appears to be a groundwater plume and with the understanding that groundwater plumes change with the passage of time, future monitoring may be warranted. As an alternative to long term monitoring, pre-emptive vapor mitigation may be favorable. The approach used to address the potential for long-term vapor intrusion issues should be developed in concert with the Program. Mid -Atlantic evaluated several lines of evidence in an effort to determine if the solvents detected in groundwater near the northeast corner of the building resulted from subject site activities. The findings are summarized below. Soil samples were collected in the most probable source areas near the northeast corner of the building. Since there are no known subsurface tanks or piping systems used for the storage of solvents in this area, the samples were collected from shallow soils to identify potential surface releases. Chlorinated solvents were not detected in any of the soil samples collected at the subject site. Therefore, evidence of a solvent source near the northeast corner of the building was not identified during the soil assessment. Groundwater assessment was conducted using three shallow -deep well pairs located between a known solvent release site on the adjacent Apex Tools property and an area of known groundwater contamination on the subject site near the northeast corner of the building. These wells are located parallel to the estimated groundwater flow direction with the MW-1/MW-1 D pair located hydraulically up gradient from the MW-3/MW-3D well pair (based on NCDENR file data associated with the Apex Tool site). The MW-1/1 D well pair is located hydraulically down gradient of a known chlorinated solvent source area on the adjacent Apex Tool property (based on NCDENR file data associated with the Apex Tool site). Historic evaluation of the use of this northern area of the subject site did not indicate the storage, handing or use of chlorinated solvents occurred in this area of the subject site. The groundwater quality and flow direction data suggest that the solvents detected in samples collected from MW-1 did not originate from the subject site. A comparison of the groundwater laboratory data available from the NCDENR adjacent to the solvent source area on the Apex Tool site and the sample collected on the subject site nearest the source area on the Apex Tool site show similar types of compounds are detected in both areas. This suggests that the source of the solvents in both of these wells is similar. Given the proximity of MW-1 to the source Ift Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Wurst Property Apex, North Carolina March 2, 2015 Page 5 area on the Apex Tool site, it appears likely that the source of the solvents near MW- 1 is from the Apex Tool site. The concentrations of the solvents in the groundwater nearest the known source area on the adjacent property (MW-1, up gradient) are much greater than the concentrations detected in the groundwater sample collected at the northeast corner of the building (MW-3, down gradient). Evaluation of these data does not suggest the presence of an additional subject site source of solvents in groundwater. A comparison of the groundwater laboratory data collected from the shallow well closest to the adjacent property source area (MW-1) and the sample collected near the northeast corner of the building (MW-3, which is down gradient of MW-1) show similar types of compounds are detected in both samples. This suggests that the source of the solvents detected in samples collected from both of these wells is similar. As stated earlier, it appears likely that the source of the solvents detected in samples collected from MW-1 is on the Apex Tool site. The solvent concentrations in the sample collected from MW-2 are substantially lower than that observed in samples collected from wells MW-1 (up gradient) or MW- 3 (down gradient). At first this appeared to suggest the solvents detected in samples collected from wells MW-1 and MW-3 might not originate from the same source. However, evaluation of the NCDENR files suggests that a similar pattern was observed in samples collected from wells used to assess the release from the Apex Tool site. There appears to be a geologic formation that runs northeast -southwest through the area of MW-2 that retards the migration of the solvents. Further evidence of its presence was substantiated by the fact that very little water was present in MW- 2 and MW-21D was dry. The assessment of soil and groundwater described herein, along with the information reviewed in the NCDENR files for the Apex Tool site, did not reveal data to suggest that there is an on -site source for the solvents detected in the groundwater near the northeast corner of the building. 46 Mid Atlantic Engineering & Environmental Solutions DRAWINGS Mid Atlantic Engineering & Environmental Solutions 1.

Fmm GW-1 Norm Carolina Depammin ofEnvi.-. aM Nvuml Resources- Division ofWa¢r Quality Rmijarc -2013 APPENDIX B PROCEDURES Mid Atlantic Engineering & Environmental Solutions Sub -Slab Soil Vapor Sampling Procedures Sub -slab soil vapor samples will be collected following this general procedure. A rotary - impact drill equipped with a spline drill bit is utilized to drill a 5/8-inch diameter hole through the concrete slab. A vapor sampling probe is established using a 'Vapor PinTM" a brass or stainless steel barb fitting with a silicone sleeve that creates a seal with the concrete when inserted snugly into the hole via an installation/extraction tool. The Vapor Pin is then fitted with small diameter (1 /8- or 1/4-inch outer diameter - OD) rigid -wall tubing (e.g., nylon or Teflon) to complete the vapor sampling probe assembly. At this point, the sampling probe is intact and the tubing can be connected to: • An apparatus to perform leak -checking, • Syringes and/or Tedlar bags to obtain sub -slab grab samples (e.g., for leak check gas monitoring, radon gas analysis, etc.), and/or • Evacuated Summa canisters for collection of sub -slab vapor for laboratory analysis by EPA Method TO-15. Leak Check A real-time leak check will be performed at each probe location using a plastic shroud, helium gas, and a portable helium gas detector. The test ensures an air tight seal at the sample probe site and allows checking for leaks in the sample fittings and other tubing connections not contained within the shroud. The plastic shroud is placed over the soil vapor probe location with the tubing of the probe exiting the shroud through a small hole. A 3-way valve placed on the probe termination is connected to the sampling apparatus that is to be used. For the tubing sizes proposed, four purge volumes will be removed using a clean 60-milliliter (mL) syringe. The volume to be purged is calculated approximately as follows - 4 mL per foot (mL/ft) for 1/8-inch OD tubing and 20 mL/ft for'/4" OD tubing. A "shut in" test is performed to check for leaks in all sample fittings and connections not contained within shroud. This is achieved by shutting the valve at the probe termination to the off position, then applying a vacuum to all connections between the valve and the sample container (i.e. syringe or Summa canister). An in -line vacuum gauge may be used to observe any loss in vacuum over a period of time (i.e. 60 seconds), which would indicate a leak in the system. For this project, vacuum loss will be assessed manually by observing the back pressure on the syringe. For the leak check, helium is released into the shroud via tubing from the cylinder into the shroud. A hand held helium detector is used to monitor and maintain a reasonably steady concentration of approximately 50% helium in the shroud. Once the concentration is reached, the soil vapor probe is purged at the recommended flow rate and any probe vacuum is recorded. A Tedlar bag is then collected from the probe by connecting to the exhaust port of the purge syringe to fill. The contents of the Tedlar bag are then screened with the helium detector. If the concentration in the bag is <_10% of the helium Mid Atlantic Engineering & Environmental Solutions concentration in the shroud, no leaks are assumed and sampling may continue. If helium concentration in the Tedlar bag is >10% of the shroud concentration, the sampling is stopped and efforts to improve or replace the probe are made. Soil Gas Sample Collection The soil vapor samples are then collected in the appropriate sample container (i.e. syringe or Summa canister). A stainless steel "Summa" canister will be attached to the probe tubing to collect the sub -slab soil gas air samples for laboratory analysis of volatile organic compounds (VOCs) by EPA Method TO-15. The canister is fitted with a flow regulator (choke) to allow collection of the sample at a rate of approximately 200 mL per minute. Therefore, the duration of the soil gas sample collection is approximately two minutes. The beginning and ending vacuum pressures of each canister are logged. Upon completion, a final reading of the shroud helium concentration is measured with the meter and recorded, and then the canister is submitted to an accredited laboratory for analysis. Following sample collection, the Vapor Pins and associated tubing are removed and the borehole in the concrete floor is patched with cement grout. Mid Atlantic Engineering & Environmental Solutions Soil Sampling Procedures I. Sample Collection Direct Push Technology QPT, or "Geoprobe") DPT uses a vehicular -mounted hydraulic rig to push a steel sampling probe into the subsurface to collect soil and/or groundwater samples. The sampling device used to collect the soil samples during this investigation was the "macrocore" sampler. This sampler consists of a four -or -five-foot long, two-inch diameter stainless steel spoon containing a clear, acetate liner. When the macrocore sampler is driven into the subsurface, the soil is collected into the acetate liner and then retrieved to the land surface. The liner is then cut open and the soil lithology is characterized and soil samples are collected. Split Spoon Sampling This method of soil sampling is typically used during advancement of hollowstem augers for the construction of monitoring wells. Soil samples are obtained from the borings by driving a prewashed, 1-3/8-inch inner -diameter split -spoon sampler at five foot intervals to termination in general accordance with ASTM D-1586 (Standard Penetration Test) specifications. Blow counts for each six inches of split -spoon penetration are recorded during advancement of the spoon. Samples are then retrieved to the land surface, the split - spoon is opened, and the soil lithology is characterized and soil samples are collected. Hand Augering This method is typically used for shallow sampling in areas where access is limited or underground obstacles such as utilities may be present. A pre -washed, three-inch diameter steel auger bucket is attached to extension rods and manually turned to penetrate the subsurface to the desired sampling depth. Samples are then retrieved to the land surface and the soil lithology is characterized and soil samples are collected directly from the hand auger bucket. Excavator Bucket Sampling This method is typically used during UST excavation and soil excavation projects. The soil samples are collected from the excavator bucket when it is not safe to collect the samples by other means. Care is taken when collecting samples from the bucket to avoid soil that has come in contact with the bucket itself to avoid cross contamination. Mid Atlantic Engineering & Environmental Solutions II. Headspace Field Screening A portion of each sample is removed from the sampling device and placed in a pre -labeled, plastic "ziploc" bag. After several minutes, the gas contained in the "headspace" or void area within the bag is tested with a photoionization detection (PID) and/or Flame Ionization Detector (FID). These are useful as scanning devices to detect the presence of volatile organic compounds (VOCs) but are not relied upon to determine specific levels of contamination. Typically, the samples exhibiting the highest headspace readings will be submitted to the laboratory for analysis. III. Preparation for Laboratory Analysis The sample collector dons new nitrile sampling gloves prior to handling each sample. The samples are placed into laboratory -prepared, pre -labeled, sampling containers, packed in ice, and shipped to a certified laboratory under chain -of -custody control. The sampler places an executed custody seal on the cooler prior to leaving the sampler's custody. Laboratory analyses to be performed on the samples, along with other sampling information, are specified on the chain -of -custody, which is placed in the cooler with the samples. Mid Atlantic Engineering & Environmental Solutions Monitoring Well Sampling Procedures Sample Collection A. Monitoring Wells Prior to sample collection, each well is purged of three to five standing well volumes or to dryness to remove stagnant water from the well and well bore in an effort to collect samples that are representative of the water quality in the formation surrounding each well. Purging is performed either with a new, polyethylene bailer dedicated to each well, or with a decontaminated pump. Samples are retrieved from the monitoring well using the dedicated bailer. New nylon string is used on each dedicated bailer, and new nitrile sampling gloves are donned prior to purging and sampling of each well. B. Geoprobe "Screen Point Sampler" The screen point sampler is a "grab" sampling device that is driven into the saturated zone and a surrounding metal sheath is retracted, exposing a screen. Groundwater entering the screen is then drawn to land surface through disposable tubing that is placed through the hollow push rods. The sample is collected from the tubing into the appropriate sampling glassware. C. Water -Supply Wells Water samples are typically collected from the available spigot that is nearest to the well. The water is allowed to run at a high flow from the spigot for approximately 10 to 15 minutes to allow the water in the delivery lines to be purged. The sample flow is then reduced and the samples are collected directly into pre -labeled containers as described below. New nitrile sampling gloves are donned prior to sampling of each well. D. Treatment System Influent/Effluent Samples are typically collected from the influent or effluent of pump -and -treat groundwater remediation systems using designated sampling ports in the influent and effluent water transport lines. The water is typically allowed to run for several seconds to clear potential debris in the sampling port. The sample is then collected directly into sampling containers as described below. New nitrile sampling gloves are donned prior to sample collection. II. Preparation for Laboratory Analysis Groundwater samples are decanted directly into laboratory -prepared, pre -labeled, sampling containers, packed in ice, and shipped to a certified laboratory under chain -of - custody control. Laboratory analyses performed on the samples are specified on the chain - of -custody.

L-01 Laboratory fortified blank /laboratory control sample recovery outside of control limits. Data validation is not affected since all results are 'hot detected" for all samples in this batch for this compound and bias is on the high side. L-03 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this compound is likely to be biased on the low side. L-05 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this compound is likely to be biased on the high side. V-05 Continuing calibration did not meet method specifications and was biased on the low side for this compound. Increased uncertainty is associated with the reported value which is likely to be biased on the low side.

SW-846 8260B Qualifications: Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side. Analyte & Samples(s) Qualified: Diisopropyl Ether (DIPE), Methyl tert-Butyl Ether (MTBE), tert-Butyl Ethyl Ether (TBEE) 15A0681-01[VSB-1 (1)], 15A0681-02[VSB-1 (8)], 15AO681-03[VSB-2 (1)], 15A0681-04[VSB-2 (8)], 15AO681-05[VSB-3 (1)], 15A0681-06[VSB-3 (8)], 15AO681-07[VSB-4 (1)], 15AO681-08[VSB-4 (8)], B114110-BLKI, B114110-BS1, Bl l4110-BSDI Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but the other is within limits. RPD between the two LFB/LCS results is within method specified criteria. Analyte & Samples(s) Qualified: 2,2-Dichloropropane, Acetone, tert-Amyl Methyl Ether (TAME) B114110-BSI Continuing calibration did not meet method specifications and was biased on the low side for this compound. Increased uncertainty is associated with the reported value which is likely to be biased on the low side. Analyte & Samples(s) Qualified: Diisopropyl Ether (RIPE), Methylene Chloride, Naphthalene, tert-Butyl Alcohol (TBA), tert-Butyl Ethyl Ether (TBEE) 15A0681-01[VSB-1 (1)], 15AO681-02[VSB-1 (8)], 15AO681-03[VSB-2 (1)], 15AO681-04[VSB-2 (8)], 15AO681-05[VSB-3 (1)], 15AO681-06[VSB-3 (8)], 15AO681-07[VSB-4 (1)], 15AO681-08[VSB-4 (8)], B114110-BLKI, B114110-BS1, Bl l4110-BSDI Continuing calibration did not meet method specifications and was biased on the high side. Data validation is not affected since sample result was "not detected" for this compound. Analyte & Samples(s) Qualified: Acetone B114110-BS1, B114110-BSD1 The results of analyses reported only relate to samples submitted to the Con -Test Analytical Laboratory for testing. I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the best of my knowledge and belief, accurate and complete. . �7P-A - Johanna K.

J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated concentration (CLP J-Flag). L-04 Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side. L-07 Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but the other is within limits. RPD between the two LFB/LCS results is within method specified criteria. U Analyte included in the analysis, but not detected V-05 Continuing calibration did not meet method specifications and was biased on the low side for this compound. Increased uncertainty is associated with the reported value which is likely to be biased on the low side. V-20 Continuing calibration did not meet method specifications and was biased on the high side. Data validation is not affected since sample result was "not detected" for this compound.

E Reported result is estimated. Value reported over verified calibration range. J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated concentration (CLP J-Flag). L-06 Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the high side. RL-11 Elevated reporting limit due to high concentration of target compounds. RL-13 Elevated reporting limit due to high concentration of non -target compounds.
