Graham Street in Charlotte, North Carolina. A site location map is included as Figure 1, and site map is included as Figure 2. In 2011, Premier Transportation (Premier) decided to enclose a portion of the site loading dock. It eventually elected to enclose the eastern portion of the loading dock and, in accordance with the Brownfields Agreement (BFA) for the site and a work plan approved by the North Carolina Department of Environment and Natural Resources (DENR) Brownfields Section, H&H conducted sub-slab soil vapor sampling beneath that portion of the loading dock. Sub-slab soil vapor samples VMP-1 through VMP-3 were collected from below the eastern end of the loading dock in July 2011 (Figure 3). Results of the sampling did not indicate any compound concentrations above DENR Inactive Hazardous Sites Branch (IHSB) industrial/commercial soil gas screening concentrations (SGSCs). The July 2011 soil vapor assessment activities and results were presented in a soil vapor sampling report dated August 26, 2011 which was submitted to DENR. Upon DENR concurrence, the eastern portion of the loading dock was subsequently enclosed. Premier now proposes to enclose the western portion of the loading dock. Accordingly, to comply with the BFA for the site, H&H is submitting this vapor intrusion mitigation work plan for that portion of the dock. 2 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc Data exist concerning sub-slab conditions under the western portion of the dock. Before deciding to enclose the eastern portion of the dock, Premier had considered enclosing the western portion. It eventually abandoned that plan for business reasons. Before doing so, in May 2011, Premier asked H&H to collect three sub-slab soil vapor samples beneath the western end of the dock. The results of the soil vapor analyses indicated the presence of tetrachloroethene (PCE) above DENR (IHSB) industrial/commercial SGSCs in all three samples. No other compounds were detected above the screening levels. The May 2011 soil vapor assessment activities and sample results are discussed in Section 2.1. The western end of the loading dock where elevated levels of PCE were detected in sub-slab soil vapor samples in May 2011 is located adjacent to the site office building. Therefore, to assess for the potential for vapor intrusion into the office space from nearby soil vapor, Premier requested that H&H collect indoor air samples within the office space in August 2011. The indoor air assessment activities and sample results are discussed in Section 2.2. The source of the elevated levels of PCE in soil vapor below the western loading dock is not known. PCE has been detected in ground water in low levels near the eastern portion of the loading dock, but no monitor wells were located near the western end of the loading dock. To evaluate if the source of the PCE could be upgradient, two ground water monitor wells (HHMW- 2 and HHMW-3) were installed in July 2011 in the western upgradient portion of the site in the locations shown in Figure 2. PCE was not detected in the two upgradient wells. Monitor well installation activities and sample results are discussed in Section 2.3. As noted, Premier would like to enclose the remaining (western) portion of the loading dock. In accordance with the BFA, Premier is submitting this work plan for vapor intrusion mitigation activities to be conducted as part of the western loading dock enclosure. Details concerning the mitigation system are included in Section 3.0. 3 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc 2.0 Assessment Activities 2.1 Soil Vapor Sampling In May 2011, H&H collected three sub-slab soil vapor (SSV) samples beneath the western end of the site loading dock to assess the potential for vapor intrusion in that area. H&H collected the three SSV samples (identified as SSV-1 through SSV-3) beneath the loading dock that Premier now plans to enclose. The sampling was conducted in accordance with the approved Soil Vapor Sampling Work Plan dated April 29, 2011, and DENR’s May 5, 2011 response letter to the work plan. The May 2011 sample locations and the area of the loading dock which is planned to be enclosed are shown in Figure 3. The methods and results of the sub-slab soil vapor sampling are discussed in the following sections. 2.1.1 Soil Vapor Sampling Methods Each SSV sample point was installed by first drilling a 1.5-inch diameter boring through the concrete slab at each SSV location. At each location, the concrete slab was observed to be approximately six inches thick and to sit on top of approximately one inch of gravel. The gravel layer was observed to be underlain by orange-red silty clay. To construct each SSV sample point, a dedicated AMS stainless steel vapor sample point fitted with a length of 0.25-inch diameter Teflon® tubing was inserted through the borehole and seated in the soil at the bottom of the boring. Filter sand was then poured through the borehole about the vapor tip to approximately 4 to 5 inches below the top surface of the slab. Each SSV sample point was then completed by installing hydrated bentonite in the annular space about the sample tubing from the top of the sand to the top surface of the concrete slab. Following installation of each SSV sample point and prior to collection the vapor sample from the point, a leak check of the SSV sample point was conducted. The leak check was performed by first placing a shroud over the SSV sample point, filling the shroud helium gas, and using a 4 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc helium gas detector to verify that the shroud was saturated with helium gas. Then, the SSV sample point was purged using a syringe and a three-way valve to collect purged vapor into a Tedlar® bag. The purged vapor was subsequently analyzed using the helium gas detector to ensure that helium concentrations were less than 10% of the helium concentrations in the shroud. Following successful leak check of each SSV sample point, laboratory-supplied sample equipment was constructed into a sample train that included a 6-liter Summa canister that was connected to a flow regulator. The flow regulator was set to collect the sample during an 8-hour period. The intake orifice of the flow regulator was connected directly to the SSV sample point tubing using a ferrule to form an air-tight seal with the tubing. Following assembly of the sample train, the Summa canister’s air intake valve was opened to begin collection of the soil vapor sample. Following completion of the sampling, the SSV points were removed and the borings were abandoned. As part of the sampling effort, H&H also measured wind speed and direction outside of the loading dock and indoor/outdoor temperatures were recorded near the start, middle, and end of the sampling period. A light rain occurred at the beginning of the event, but stopped after the start of the sampling. The results of the air sampling measurements of wind speed, wind direction, and temperature are summarized in Table 1. After sample collection, the regulator valves on the canisters were closed and the sample train was disassembled. The Summa canisters were properly labeled, placed into laboratory-supplied shipping containers, and shipped under standard chain-of-custody protocols to Con-Test Analytical Laboratory in East Longmeadow, MA for analysis of volatile organic compounds (VOCs) by EPA Method TO-15. 5 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc 2.1.2 Soil Vapor Sample Results A summary of the soil vapor sample analytical results are included as Table 2. The laboratory analytical report for the soil vapor samples is provided as Appendix A. The concentrations of compounds detected in the soil vapor samples were compared to the DENR IHSB Industrial/Commercial SGSCs. As indicated in Table 2, multiple compounds were detected in the samples. With the exception of PCE, the compounds were detected in low concentrations below SGSCs. PCE was detected in SSV-1 (33,000 µg/m3), SSV-2 (17,000 µg/m3), and SSV-3 (1,300 µg/m3) at levels above the industrial/commercial SGSC for PCE of 210 µg/m3, which is based upon a lifetime incremental cancer risk (LICR) of 1 x 10-5. 2.2 Indoor Air Sampling As discussed above, elevated levels of PCE were detected in sub-slab soil vapor beneath the western end of the loading dock which is located adjacent to the site office building. In order to assess for the potential for vapor intrusion into the office space from nearby soil vapor, H&H collected indoor air samples within the office space in August 2011. The methods and results of the indoor air sampling are discussed in detail in the following sections. 2.2.1 Indoor Air Sampling Methods On August 13, 2011, H&H collected two indoor air samples from the main office area of the site building. In addition, a background air sample was collected from an outdoor location that was upwind of the office building (as determined by H&H personnel at the time of sampling). The locations of the indoor air samples, (identifies as IAS-1 and IAS-2), and the background air sample (identified as BAS-1) are indicated in Figure 3. 6 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc At the time of the sampling activities, the office space had recently been remodeled (including painting, ceiling tile replacement, and floor refinishing). Remodeling activities were finished approximately one week prior to indoor air sampling activities. The sampling activities were conducted during the weekend when the office space was uninhabited; however, the heating ventilation and air conditioning (HVAC) system was allowed to run as it would during a normal working day. Doors between the office space and the exterior and loading dock were kept closed during the sampling, except when opened and closed for the purposes of access. Each ambient air sample was collected using laboratory-supplied sample equipment constructed into a sample train which included a 6-liter Summa canister that was connected to a flow regulator. The flow regulator was set to collect the sample during an 8-hour period. The intake orifice of the flow regulator was connected to a 3 ft long sampling cane used to extend the sample intake to approximately 5 ft above grade (typical breathing zone height). After collection of each sample was complete, the regulator valve on the canister was closed and the sample train was disassembled. Each Summa canister was properly labeled, placed into laboratory-supplied shipping containers, and shipped under standard chain-of-custody protocols to Con-Test Analytical Laboratory in East Longmeadow, MA for analysis of PCE and its primary degradation products (trichloroethene, cis-1,2-dichloroethene, trans-1,2-dichloroethene, and vinyl chloride) by EPA Method TO-15. 2.2.2 Indoor Air Sample Results The results of the indoor sampling indicate that, with the exception of PCE, no compounds were detected in either of the indoor air samples or the background sample. Low levels of PCE were detected in both indoor air samples IAS-1 (0.37 µg/m3) and IAS-2 (0.54 µg/m3), and background air sample BAS-1 (0.14J µg/m3). The detected concentrations are below the DENR IHSB industrial/commercial indoor air screening level of 2.1 µg/m3. The DENR screening level is 7 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc based upon very conservative assumptions and a LICR of 1 x 10-6. DENR typically only requests indoor air mitigation at industrial/commercial facilities when the LICR exceeds 1 x 10-4. The PCE screening level based upon a LICR of 1 x 10-4 is 210 µg/m3. The detected PCE indoor air concentrations are several orders of magnitude less than the DENR screening level based upon a LICR of 1 x 10-4. The laboratory analytical report for the indoor air samples is provided as Appendix B. 2.3 Upgradient Ground Water Assessment As mentioned in Section 1.0, the source of the elevated levels of PCE in soil vapor below the western loading dock is not known. PCE has been detected in groundwater in low levels near the eastern portion of the loading dock, but no monitor wells were located near the western end of the loading dock. To evaluate if the source of the PCE could be upgradient, two ground water monitoring wells were installed in the western upgradient portion of the site and the wells were sampled in July 2011. The monitor wells are identified as HHMW-2 and HHMW-3 in Figure 2. The methods and results of the monitor well installation and sampling are discussed in detail in the following sections. 2.3.1 Monitor Well Installation and Sampling Methods On July 22, 2011, H&H oversaw the installation of monitor wells HHMW-2 and HHMW-3 in the western (hydraulically upgradient) portion of the site to assess the potential for migration of compounds in ground water from an upgradient source (Figure 2). Monitor wells HHMW-2 and HHMW-3 were installed to total depth of 25 and 30 ft bgs, respectively, and are both constructed of 2-inch diameter PVC casing and screen. Monitor well HHMW-2 was constructed with 15 ft of well screen and HHMW-3 was constructed with 20 ft of well screen. After installation, each well was developed until the turbidity measured less than 50 8 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc NTU and field parameters of pH, conductivity, and temperature stabilized. Well construction records are provided in Appendix C. Ground water samples were collected from the newly installed monitor wells on August 13, 2011. Prior to sample collection, H&H purged the wells until field measurements of pH, conductivity, temperature, dissolved oxygen, and turbidity stabilized, and turbidity measurements were less than 10 NTU. Groundwater samples were then collected using low-flow sampling methods. After ground water parameters stabilized during purging, ground water from each monitor well was poured directly into laboratory-supplied containers, which were then sealed, labeled, placed into laboratory-supplied sample coolers, and covered with ice. The coolers were delivered under standard chain-of-custody protocols to Test America of Nashville, TN to be analyzed for (VOCs) by EPA Method 8260. Following installation, the tops of casing of the two newly installed monitor wells were determined using survey techniques. The tops of casing were referenced to the existing monitor well network. H&H collected water levels from the two newly installed wells and six of the existing site wells on August 13, 2011 to evaluate groundwater flow direction. The ground water elevation data indicate that ground water flow is generally to the east-southeast beneath the site. 2.3.2 Ground Water Sample Results The results of the groundwater sample analysis indicate that no VOCs were detected in either sample. The laboratory analytical report for the ground water samples is provided as Appendix D. 9 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc 3.0 Vapor Mitigation Plan Based upon the results of the assessment activities described in Section 2.0, vapor intrusion does not pose a concern to indoor air quality in the office building. The detected PCE concentrations are several orders of magnitude less than concentrations that would typically require mitigation. As noted in Section 1.0, Premier would like to enclose the remaining (western) portion of the loading dock where PCE was detected in sub-slab soil vapor at levels above the industrial/commercial SGSC for PCE (as discussed in Section 2.1). Premier plans to enclose an approximately 34,000 sq ft loading dock area that is currently open and covered (Figure 2). The volume of the enclosed area will be approximately 850,000 cu ft (based on a 25 ft ceiling height). The space will continue to be used as a loading dock and will include bay doors that may be opened or closed (depending on outside air temperature) during normal operating hours when a trailer is not docked to the bay. According to Premier, the area will be heated with electric overhead heating units, but not cooled. To expedite completion of the enclosure, Premier requested that H&H develop a vapor intrusion mitigation plan in accordance with the BFA. Proposed vapor mitigation activities are presented below. 3.1 Mitigation System Installation The proposed vapor mitigation will be accomplished with an active sub-slab depressurization system. This system works by applying a vacuum to the building sub-slab to reduce the pressure below the slab and thereby minimize migration of sub-slab vapor into indoor air. Vapor captured by the vacuum is discharged outside of the building to the atmosphere. The proposed vapor mitigation system will include three vacuum blowers and associated piping that will each draw vapor from a pair of sub-slab vapor extraction points. The mitigation system layout is depicted in Figure 4. 10 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc Roof support columns are aligned along the center of the loading dock and it is likely that a continuous foundation footer runs beneath the slab in-line with the columns. Because the foundation footer would likely act as a barrier that divides the sub-slab area targeted for mitigation, the extraction point pairs will be installed so that one point of each pair is located on each side of the footer. The extraction points will each be installed near a roof support column. Each extraction point will be constructed by installing a 4-inch diameter PVC pipe connected to a 3-inch reducer into a borehole drilled through the building’s slab. The intake orifice of the extraction point will be set in the gravel layer beneath the slab and the penetration will be sealed using a foam backer and silicon sealer. The pipes extending from each pair of extraction points will be joined into a single 3-inch diameter pipe above the slab and will be run up the roof support column, then along the roof support truss, and through the exterior wall of the enclosure. In addition, to allow easy verification that each system is operating, a manometer will be installed on the vertical pipe run at the column at approximately 2 to 6 ft above the floor. Finally, a protective bollard will be installed adjacent to each extraction point. Outside of the exterior wall of the enclosure, the pipe will be connected to a low voltage vacuum blower motor that will be mounted on the outdoor side of the exterior wall of the enclosure. An exhaust line will extend from the top of each vacuum blower to the edge of the structure’s roof overhang (which extends approximately 15 ft horizontally from the dock), and will discharge vapors at a height greater than 1 ft above the roof line. Electrical wiring will be run to each of the suction fans within a conduit from existing power bases located in close proximity to the vacuum blowers. Each suction fan will include a waterproof power switch protected with a lockable cover. 11 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc 3.2 Confirmation Sampling Plan Following the mitigation system installation and enclosure of the loading dock, H&H proposes to collect two indoor air samples from within the newly enclosed area in the approximate locations shown in Figure 4 to verify indoor air compound concentrations (if any) are within acceptable levels. In addition, one background air sample will be collected from an upwind location outside of the enclosed area. H&H will conduct post-mitigation confirmation indoor air sampling a minimum of 30 days after installation and startup of the mitigation systems and completion of the loading dock enclosure activities. The confirmation samples will be collected using the same methods described in Section 2.2.1. Based upon the previous sub-slab sampling data, the indoor air samples will be analyzed for PCE and its primary degradation products (trichloroethene, cis- 1,2-dichloroethene, trans-1,2-dichloroethene, and vinyl chloride) by EPA Method TO-15. 12 Hart & Hickman, PC s:\aaa-master projects\premier transportation - ptt\ptt-001 dixie trucking site\mitigation wp\premier wp.doc 4.0 Reporting Following completion of the mitigation installation activities, H&H will prepare a report which describes the methods and results of the mitigation system installation and subsequent indoor air confirmation sampling. The report will include the methods of the system installation and subsequent sampling, photographs taken during the installation, manometer readings from each system, details of the final layout of the system, field measurements taken during the sampling event, a tabular summary of the confirmation sample data, a Professional Engineer certification of installation, and conclusions and recommendations based upon the activities.

System installation contractor shall comply with applicable OSHA, state and local standards and/or regulations. System installation contractor shall confirm all field conditions as well as dimensions and positions indicated on plans and notify H&H of any conflicts with plans before proceeding with system installation. System installation contractor shall follow manufacturers’ instructions and specifications for installation and use of all materials and equipment. Systems shall be installed as permanent, integral additions to the building. Extraction Point/Slab Penetration A set of two penetrations will be installed on each side of a continuous foundation footer assumed to run beneath the slab in-line with the columns (refer to Section 3.1 of the work plan). 4 to 5-inch diameter slab penetrations shall be installed at each extraction point location. Penetrations will be installed as near a steel roof support column as possible. To the extent possible using hand tools, material shall be excavated from the area immediately below the slab penetration point at each extraction point location to provide optimum pressure field extension of the sub-slab communication zone. Extraction point pipe intakes shall be installed so that condensation water drains downward into the ground beneath the slab. Extraction point intake shall be 4-in diameter PVC or ABS, schedule 40 pipe. 2 Extraction point pipe shall be reduced from 4 to 3-in diameter PVC or ABS, schedule 40 vent pipe. Penetrations in the slab shall be sealed with materials (i.e., non-shrink mortar, grouts, expanding foam materials, elastomeric joint sealant, etc) that provide a permanent air-tight seal. Placement and tooling must be in accordance with manufacturer’s specifications and result in no gaps or voids after curing. A minimum 4-in diameter x 3 ft tall steel bollard shall be installed adjacent to each extraction point on the side opposite of the roof support column. Vent Pipe 3-in diameter vent pipe shall run from the extraction point reduction joint of each slab penetration to the roof support column and the two vent pipes from the set of penetrations shall be joined using a three-way connector. A single 3-in diameter vent pipe shall run from the connector to the mitigation fan and from the mitigation fan to the point of exhaust discharge. Vent pipes shall be installed so that condensation water drains downward into the ground beneath the slab. Vent piping shall be 3-in diameter PVC or ABS, schedule 40. All vent pipe joints and connections shall be permanently sealed with adhesives as specified by the manufacturer of the pipe material. Joints and connections shall be made air tight. Point of exhaust venting discharge shall be a minimum of 12 inches above the roofline, 10 feet or more above ground level, and 10 feet or more from any operable window, chimney, door, or other openings into conditioned spaces of building that is less than 2 feet below the exhaust point. Where installation requires pipes or ducts to penetrate a firewall or other fire resistance rated wall, penetrations shall be protected in accordance with applicable building, mechanical, and electrical codes. All positively pressurized portions of vent pipe (i.e., pipe from the mitigation fan to the point of exhaust discharge) shall be located outside habitable space of the building. Vent pipes shall be fastened to the structure of the building with hangers, strapping, or other supports that shall adequately secure the vent pipe material. Supports shall be installed a minimum of every 10 ft on horizontal runs. Vertical runs shall be secured either above or below the points of penetration through the slab, or a minimum of 10 ft on runs that do not penetrate the slab. These pipes shall be supported or secured in a permanent manner that prevents their downward movement into the soil beneath the slab. 3 Mitigation System Fan Mitigation fans shall contain minimum 3-in diameter fan duct and be minimum 40 to 60 watt units. The fans must be capable of producing a minimum 2.0 inches water column (in WC) pressure (vacuum) and 5.0 cubic ft per minute air flow when operated at 2.0 in WC. Mitigation fans shall be designed or otherwise sealed to reduce the potential for leakage of soil gas from the fan housing. Mitigation fans shall be installed on an exterior portion of the building and in an accessible location. Mitigation fans shall be rated for outdoor use or installed in a water tight protective housing. Mitigation fans shall be installed in a vertical run of the vent pipe. Mitigation fans shall be installed in a configuration that minimizes condensation buildup in the fan housing. Mitigation fans shall be mounted and secured in a manner that minimizes transfer of vibration to the structural framing of the building. Mitigation fans shall be connected to vent pipe using removable couplings or flexible connections that can be tightly secured to both the fan and the vent pipe. Electrical Electric wiring shall conform to provisions of the National Electric Code and any additional local regulations. Electric wiring shall not be located in or chased through the mitigation installation ducting or any other heating or cooling ductwork. Mitigation fans shall be hard-wired into an electrical circuit. An electrical disconnect switch shall be installed in mitigation fan circuits to permit deactivation of the fan for maintenance or repair. System Monitoring and Labeling Mitigation systems shall include a u-tube manometer that clearly displays units of pressure in inches of water column. The manometer shall be located on the vent pipe (above the three-way connector that joins the two vent pipes from the set of penetrations) where it is easily seen by building occupants and protected from damage or destruction. The manometers shall be clearly 4 marked to indicate the range or zone of pressure readings that existed when the system was initially activated. Mitigation system fan housings, electric switches, and vent pipe approximately 5 ft above the slab penetration shall be labeled "SOIL VAPOR MITIGAITION SYSTEM.” The labels shall be legible from a distance of at least three feet. In addition, circuit breakers controlling the circuits on which the mitigation system fan operates shall be labeled “MITIGATION SYSTEM.”
