The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify actions to be taken during the demolition and construction at Brownfields properties in an effort to avoid delays in the event of the discovery of new contamination sources or other environmental conditions. The EMP provides a means to document redevelopment plans and environmental data for each applicable environmental medium to inform regulatory-compliant decision-making at the site. As much detail as possible should be included in the EMP, including contingency planning for unknowns. Consult your project manager if you have questions. Prospective Developers and/or their consultants must complete and submit this form and all pertinent attachments, see checklist below, to their Brownfields project manager prior to any earthmoving or other development-related activities that have the potential to disturb soil at the Brownfields Property, including demolition. For the resultant EMP to be valid for use, it must be completed, reviewed by the program, signed by all parties working on the project, and approved by the Brownfields project manager. Failure to comply with the requirements of the EMP could jeopardize project eligibility, or in the event of a completed agreement, be cause for a reopener. The EMP is valid only for the scope of work described herein and must be updated to be applicable for new phases of redevelopment or after significant changes in applicable regulatory guidance. Voluntary Metrics Tab The NC Brownfields Program updates estimated capital investment (from the Brownfields Property Application) and estimated jobs created (from the Brownfields Agreement) whenever possible. As a voluntary measure, you may opt to complete the below information for capital investment and jobs created as estimated by your final redevelopment plans for the Brownfields Property: 1. Estimated capital investment in redevelopment project: 115,000,000 2. Estimated jobs created: a. Construction Jobs: at least 1,000 b. Full Time Post-Redevelopment Jobs: approximately 1,100 2 EMP Version 2, January 2021 Table of Contents NORTH CAROLINA BROWNFIELDS PROGRAM ENVIRONMENTAL MANAGEMENT PLAN ........................... 1 GENERAL INFORMATION ........................................................................................................................ 4 COMMUNICATIONS ................................................................................................................................ 4 NOTIFICATIONS TO THE BROWNFIELDS PROGRAM ............................................................................... 5 REDEVELOPMENT PLANS ........................................................................................................................ 6 CONTAMINATED MEDIA ......................................................................................................................... 7 PART 1.

Tabular summaries of laboratory analytical results for each sampled media are included as attachments to this EMP. PART 1. Soil 1) Known or suspected contaminants in soil (list general groups of contaminants): Assessment activities completed at the Brownfields property included the collection of soil samples in areas of planned soil disturbance during future grading activities and in areas of potential environmental concern. A tabular summary of soil sample analytical data in comparison to the North Carolina Department of Environmental Quality (DEQ) Residential and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) is included as Table 1 and soil sample locations are shown in Figure 3. A brief summary of the soil assessment results is provided below. Volatile Organic Compounds (VOCs) Laboratory analytical results indicate that low levels of several VOCs have been detected in soil samples collected at the Site at concentrations above laboratory method detection limits, but below the DEQ Residential and Industrial/Commercial PSRGs. Semi-Volatile Organic Compounds (SVOCs) Laboratory analytical results indicate a low level of bis(2-Ethylhexyl)phthalate was detected in one soil sample collected from the east-central portion of the Site at a concentration above the laboratory method detection limit, but below the DEQ Residential and Industrial/Commercial PSRGs. No other SVOCs were detected in the soil samples collected at the Site. Metals As expected, several metals were detected at concentrations above the laboratory method detection limits in each soil sample. The detected metals concentrations are generally consistent with both published and Site-specific background levels and are considered representative of naturally occurring levels. No metals were detected at concentrations above the Industrial/Commercial PSRGs in soil samples collected at the Site. 9 EMP Version 2, January 2021 2) Depth of known or suspected contaminants (feet): Soil samples were collected at depths ranging from 0 to 8 ft from across the Site. However, laboratory analytical results indicate that no compounds have been detected at concentrations above the DEQ PSRGs (or background levels in the case of metals) in soil samples collected at the Site. 3) Area of soil disturbed by redevelopment (square feet): Approximately 4,000,000 square feet of the Brownfields property will be cleared and graded as part of Site work activities. As noted above, a 90-foot trail easement located along the western Site boundary within an undisturbed buffer and an approximately 3-acre portion of Parcel 3 in the southernmost portion of the Site will be dedicated to Mecklenburg County and will not be included in the Brownfields property or the proposed Rapid Commerce Park redevelopment. 4) Depths of soil to be excavated (feet): The preliminary grading plan with cut/fill analysis for the Rapid Commerce Park project is provided in Appendix C (includes the subject Site and adjacent 438-621 Rhyne Road Brownfields property). As indicated on the grading plan, cut at the Site is generally planned in the northern, western, and southeastern portions of the Site. The deepest planned cut depths are expected to extend to approximately 30 ft below current grade elevations. Other discrete areas may include deeper excavations for the installation of foundational footers, utility banks, etc. Remaining portions of the Site are planned fill areas and it is expected that soil generated in areas of cut during grading activities will be re-used on-Site. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Based on review of the grading plan and cut-fill analysis (Appendix C), over 700,000 cubic yards of soil will be excavated during grading activities completed for the entire Rapid Commerce Park project. Excess soil generated during the proposed redevelopment of the Site will be re-used as fill material and will likely include the transfer of soil between the Rhyne Road Assemblage and the adjacent 438-621 Rhyne Road Brownfields property. Grading activities will be completed across the entire industrial park project resulting in the transfer of soil from one Brownfields property to the other as needed. Given the similar soil conditions on both properties, separate DEQ approval is not required for such soil transfer unless field observations indicate an area of potentially impacted soil, in which case potentially impacted soil will be managed as described in the Managing On-Site Soil section below. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Based on soil sample results and review of the cut-fill analysis, it is unlikely grading activities will encounter areas of impacted soil that will need to be managed. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: As described above, the discovery of impacted soil is not anticipated at this time. Based on review of the preliminary grading plan and cut-fill analysis, excess soil generated during grading activities will be re-used as fill material on Site or on the adjacent 438-621 Rhyne Road Brownfields property. 10 EMP Version 2, January 2021 Grading activities will be completed across the entire industrial park project resulting in the transfer of soil from one Brownfields property to the other as needed. As noted above, separate DEQ approval is not required for such soil transfer unless field observations indicate an area of potentially impacted soil. In the unlikely event potentially impacted soil is encountered and cannot be reused the Brownfields properties as fill, it will be sampled and managed in accordance with the procedures described in the following sections. Part 1.A. MANAGING ONSITE SOIL If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields Property, or otherwise disturbed during site grading or other redevelopment activities, please provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are acceptable, if only preliminary data available). 1) HAZARDOUS WASTE DETERMINATION: a) Does the soil contain a LISTED WASTE as defined in the North Carolina Hazardous Waste Section under 40 CFR Part 261.31‐261.35?....................................... ☐Yes ☒No ☐ If yes, explain why below, including the level of knowledge regarding processes generating the waste (include pertinent analytical results as needed).

Please provide a description of the measure: 4) Please describe the following action(s) to be taken during and following excavation and management of site soils: Management of fugitive dust from site ☒ Yes, describe the method will include: Areas of potentially contaminated soil are not expected to be encountered or disturbed during Site redevelopment activities based upon soil sampling data and historical uses of the Site (undeveloped wooded land). The grading contractor will consider conditions such as wind speed, wind direction, and moisture content of soil during soil grading and stockpiling activities to minimize dust generation. In the unlikely event that potentially contaminated soil is encountered during redevelopment that requires excavation, particular attention will be paid by contractors to implement dust control measures as needed based on site and atmospheric conditions (i.e., by controlled water application, hydro-seeding, and/or mulch, stone, or plastic cover). Potentially impacted soil will be managed as described below. ☐ No, explain rationale: Click or tap here to enter text. Field Screening of site soil ☒ Yes, describe the field screening method, frequency of field screening, person conducting field screening: During soil disturbance at the Site, the workers or contractors will observe soil for evidence of potentially impacted soil. Evidence of potentially impacted soil includes a distinct unnatural color, strong odor, or filled or previously disposed of materials of concern (i.e., chemicals, tanks, drums, etc.). Should the above be observed during Site work, the contractor will contact the project environmental professional to observe the suspect condition. If the project environmental professional confirms that the material may be impacted, then the procedures below will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours to advise the person of the condition. ☐ No, explain rationale: Click or tap here to enter text. Soil Sample Collection ☐ Yes, describe the sampling method (e.g., in‐situ grab, composite, stockpile, etc.): Click or tap here to enter text. ☒ No, explain rationale: If potential soil impacts are encountered during grading and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading or other Click or tap here to enter text. 13 EMP Version 2, January 2021 construction-related activity to continue and/or only as far as needed to allow alternate corrective measures as described below. Suspect potentially impacted soil excavated during redevelopment activities may be stockpiled and covered in a secure area to allow for construction to continue. Suspect impacted soil will be stockpiled in accordance with Figure 1, NCBP Diagram for Temporary Containment of Impacted or Potentially Impacted Soil. At least one representative soil sample (no less than 3 aliquot soil samples) at a sample ratio of 1 soil sample per approximately 1,000 cubic yards of soil will be collected for analysis of VOCs, SVOCs, RCRA metals, and hexavalent chromium. If the soil sample laboratory analytical results indicate that the soil could potentially exceed toxicity characteristic hazardous waste criteria, then the soil will also be analyzed by TCLP for those compounds that could exceed the toxicity characteristic hazardous waste criteria. Impacted soil will be managed in the manner described below based on the laboratory analytical results: i. If no organic compounds or metals are detected in a sample (other than those attributable to sampling or laboratory artifacts) above unrestricted use PSRGs, the TCLP concentrations are below hazardous waste criteria, and the cumulative risk calculator results are acceptable, and metals concentrations are consistent with naturally occurring levels, then the soil will be deemed suitable for use as fill at the Rapid Commerce Park development or as off-Site fill. The proposed location(s) for off-Site placement of soil (other than a Municipal Solid Waste Landfill [MSWLF]) will be provided to DEQ for approval prior to taking the soil off-Site. ii. If detectable levels of compounds are found which do not exceed Industrial/Commercial PSRGs (other than which are attributable to sampling or laboratory artifacts), the TCLP concentrations are below hazardous waste criteria, and metals concentrations are consistent with naturally occurring levels, then the soil may be used at the Rapid Commerce Park development as fill without conditions. iii. If detectable levels of compounds are found which exceed the Industrial/Commercial PSRGs (other than those attributable to sampling or laboratory artifacts or are consistent with naturally occurring levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil, with prior DEQ approval, may be used as fill at the Rapid Commerce Park development below an impervious surface, at least 2 ft of compacted demonstrably clean soil, or overlain by a geotechnical fabric. If the impacted soil with concentrations above Industrial/Commercial PSRGs is moved to an on-Site location, its location and depth will be documented and provided to DEQ, and the impacted soil will be placed beneath at least 2 ft of compacted demonstrably clean soil, an impervious surface, or covered by a geotechnical fabric. iv. Impacted soil may be transported to an MSWLF or DEQ permitted landfarm provided that the soil is accepted at the disposal facility. DEQ Solid Waste Section and DEQ Brownfields Program approval will be requested for any potential export to an off- Site facility other than an MSWLF or DEQ permitted landfarm. If soil is transported 14 EMP Version 2, January 2021 to an MSWLF or DEQ permitted landfarm, the facility’s written approval in the form of waste manifests or similar will be included in an annual redevelopment summary report. In the unlikely event that the sample data indicates concentrations above TCLP hazardous waste criteria, then the soil must be transported off-Site to a facility that can accept or treat hazardous waste. If soil samples are collected for analysis, please check the applicable chemical analytes: ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Methods 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text. ☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Specify Analytical Method Number(s): Hexavalent Chromium by EPA Method 7199 ☒ Check to confirm that stockpiling of known or suspected impacted soils will be conducted in accordance with Figure 1 of this EMP.

Samples should be collected from 0-2 ft below ground surface, with the exception of VOCs which should be taken from 1-2 ft below ground surface. Alternatively, indicate if a work plan for final grade sampling may be submitted under separate cover. Following completion of soil disturbance for future Site development (i.e., after grading and utility construction), Hart & Hickman will observe the Site for areas that will not be covered upon completion of the redevelopment with a minimum of 2 ft of demonstrably clean fill soil, building foundations, sidewalks, asphalt or concrete parking areas, driveways, or other impervious areas (e.g., tightly spaced pavers or bricks). If such areas exist, a Work Plan will be prepared for final grade sampling for DEQ Brownfields review and approval. Final grade soil sampling will be performed at a frequency approved in advance by DEQ Brownfields . Final grade soil samples will consist of a maximum of five (5) aliquot soil samples collected from within each evaluation area which will be combined and homogenized to form one composite soil sample representative of that evaluation area and submitted for analysis of SVOCs and RCRA metals plus hexavalent chromium. In addition, one grab soil sample will be collected from each evaluation area and submitted for laboratory analysis of VOCs. If no such areas exist, documentation will be provided to the DEQ Brownfields project manager and/or the DEQ Brownfields Property Management Unit. ☐ If final grade sampling was NOT selected, please explain rationale: Click or tap here to enter text.

According to the Brownfields IR 15, “Documenting imported soil (by sampling, analysis, and reporting in accordance with review and written approval in advance by the Brownfields Program), will safeguard the liability protections provided by the brownfields agreement and is in the best interest of the prospective developer/property owner.” Requirements for importing fill: 1) Will fill soil be imported to the site?................................................ ☐ Yes ☒ No ☐ Unknown 16 EMP Version 2, January 2021 2) If yes, what is the estimated volume of fill soil to be imported? Grading for the entire Rapid Commerce Park development is expected to result in a net balance with no import or export soil required to achieve final grade elevations. 3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range of depths, please list the range.) In general, fill areas associated with the proposed redevelopment are located in the northwest, central, and southwest portions of the Rapid Commerce Park development (Appendix C). The proposed depth of fill ranges from approximately 1ft to 35 ft above current elevations. 4) Provide the source of fill, including: location, site history, nearby environmental concerns, etc. Attach aerial photos, maps, historic Sanborn maps and a borrow source site history: As indicated above, if possible, soil generated in planned cut areas will be reused as fill for the project. In the event that additional import soil is needed, the procedures outlined in Part 1.B. Section 7 below will be followed. 5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill soil to demonstrate that it meets acceptable standards applicable to the site and can be approved for use at the Brownfields property. The PD plans to import limited amounts of virgin organic rich topsoil from a commercial landscape material vendor for use in proposed landscaped areas. The PD does not plan to collect samples of landscaping materials prior to placement at the Site. In addition, the PD may use lime or concrete obtained from a reputable commercial vendor as needed during grading and redevelopment activities. The PD does not plan to collect samples of lime or concrete prior to use at the Site. The PD will follow the procedures outlined below to demonstrate import soil other than virgin organic-rich topsoil and lime or concrete meet acceptable standards applicable to the Site. 6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Methods 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text. ☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Hexavalent Chromium by EPA Methods 7199 17 EMP Version 2, January 2021 7) The scope of work for import fill sampling may be provided below or in a Work Plan submitted separately for DEQ review and approval. Attach specific location maps for in-situ borrow sites. If using a quarry, provide information on the type of material to be brought onto the Brownfields Property. The PD will follow the procedures outlined below to demonstrate import soil meets acceptable standards applicable to the Site: If the PD plans to import fill material from Vulcan Materials Company quarry located near Pineville, NC, or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC, no samples of the import material will be collected as adequate analytical data is available in the DEQ Brownfields database to demonstrate material from these facilities is suitable for use as structural fill at a Brownfields property. If fill soil is obtained from an off-Site property that is not a Brownfields pre-approved quarry or is recycled material from the Vulcan Materials Company quarry or the Martin Marietta quarries, then soil samples will be collected for laboratory analyses at a general rate of 1 sample per approximately 1,000 cubic yards. Representative composite soil samples (no less than 3 aliquot soil samples) will be collected for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Methods 6020/7471, and hexavalent chromium by EPA Method 7199. The VOC sample will be a grab sample from an undisturbed soil sample aliquot with the highest indication of potential impact. DEQ approval of the fill soil will be obtained prior to transporting import soil to the Site. Fill soil will be considered suitable for use at the Site if it does not contain compound concentrations above DEQ Industrial/Commercial PSRGs, DWM Risk Calculator risk thresholds, or typical metals concentrations that are consistent with naturally occurring levels in the Site area. Part 1.C. EXPORTED SOIL NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE BROWNFIELDS PROGRAM. FAILURE TO OBTAIN APPROVAL MAY VIOLATE A BROWNFIELDS AGREEMENT CAUSING A REOPENER OR JEOPARDIZING ELIGIBILITY IN THE PROGRAM, ENDANGERING LIABILITY PROTECTIONS AND MAKING SAID ACTION POSSIBLY SUBJECT TO ENFORCEMENT. JUSTIFICATIONS PROVIDED BELOW MUST BE APPROVED BY THE PROGRAM IN WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES. Please refer to Brownfields IR 15 for additional details. 1) If export from a Brownfields Property is anticipated, please provide details regarding the proposed export actions. Volume of exported soil, depths, location from which soil will be excavated on site, related sampling results, etc. Provide a site map with locations of export and sampling results included. Excavated soil is planned for use as beneficial fill at the Rapid Commerce Park development and soil will be moved freely between the subject Site and adjacent 438-621 Rhyne Road Brownfields 18 EMP Version 2, January 2021 property in accordance with this EMP. Grading activities will be completed across the entire industrial park project resulting in the transfer of soil from one Brownfields property to the other as needed. Given the similar soil conditions on both the properties, separate DEQ approval is not required for such soil transfer unless field observations indicate an area of potentially impacted soil, in which case the potentially impacted soil will be managed as described in the Managing On- Site Soil section above (Part 1.A.). However, if soil export is deemed necessary, in-situ or stockpile soil sampling may be performed. If soil sampling is completed for export soil, the sampling results will be presented to DEQ Brownfields for review prior to transporting soil off-Site. In general, it is anticipated that export soil sampling will include the collection of a composite sample at a rate of approximately 1 sample per approximately 1,000 cubic yards for SVOCs by EPA Method 8270, RCRA metals by EPA Method 6020/7471, and hexavalent chromium by EPA Method 7199, and one representative grab soil sample for laboratory analysis of VOCs by EPA Method 8260. Sample volume for SVOCs and metals analysis will be collected from up to 5 sample aliquot locations to form one (1) composite sample. Each aliquot will be field screened for the presence of VOCs using a calibrated photo-ionization detector (PID). VOC samples will be collected as grab samples from an undisturbed portion of the aliquot exhibiting the highest indication of impact based on field screening results. Following completion of the soil sampling activities and receipt of the analytical data, H&H will prepare a data summary package for DEQ review. The data summary package will include a tabular summary of the laboratory analytical results in comparison to the regulatory screening levels and background metals concentrations and a copy of the laboratory analytical report. H&H assumes that the data summary package can be reviewed by DEQ to provide guidance regarding potential export site selection. Based on the analytical results of soil samples collected from the export soil, the soil will be transported off-Site to a suitable location. The PD will notify DEQ Brownfields of the location receiving the export soil. If not a permitted facility (e.g., another Brownfields property), written approval from DEQ Brownfields and the receiving facility will be obtained prior to transporting the soil off-Site. If the receiving facility is a non-Brownfields property, DEQ Solid Waste Section approval will be obtained prior to transporting the soil off-Site. 2) To what type of facility will the export Brownfields soil be sent? ☒ Subtitle D/Municipal Solid Waste Landfill (analytical program to be determined by landfill) ☒ Permitted but Unlined Landfill (i.e. LCID, C&D, etc.) Analytical program to be determined by the accepting Landfill; ☒ Landfarm or other treatment facility ☒ Use as fill at another suitable Brownfields Property – determination that a site is suitable will require, at a minimum, that similar concentrations of the same or similar contaminants already exist at both sites, use of impacted soil will not increase 19 EMP Version 2, January 2021 the potential for risk to human health and the environment at the receiving Brownfields property, and that a record of the acceptance of such soil from the property owner of the receiving site is provided to Brownfields. Please provide additional details below. ☒ Use as Beneficial Fill off-site at a non-Brownfields Property - Please provide documentation of approval from the property owner for receipt of fill material. This will also require approval by the DEQ Solid Waste Section. Additional information is provided in IR 15. Please provide additional details below. 3) Additional Details: (if transfer of soil to another property is requested above, please provide details related to the proposed plans). As described throughout this EMP, the subject Site and adjacent 438-621 Rhyne Road Brownfields property (Brownfields Project No. 26016-22-060) are being developed jointly as the Rapid Commerce Park industrial park. Grading activities will be completed across the entire industrial park project resulting in the transfer of soil from one Brownfields property to the other as needed. Separate DEQ approval is not required for such soil transfer unless field observations indicate an area of potentially impacted soil. If discovered, potentially impacted soil will be managed using the procedures outlined above in Managing On‐Site Soil (Part 1.A.). The environmental professional will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ Solid Waste approval prior to exporting soil to a non-permitted facility (i.e., landfill). If soils are transferred to another Brownfields Property other than the adjacent 438-621 Rhyne Road Brownfields property, DEQ Brownfields approval will be obtained prior to transport. Part 1.D. MANAGEMENT OF UTILITY TRENCHES ☐ Install liner between native impacted soils and base of utility trench before filling with clean fill (Preferred) ☒ Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a hazardous waste), i.e., impacted soils are placed back at approximately the depths they were removed from such that impacted soil is not placed at a greater depth than the original depth from which it was excavated. ☐ Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport, and/or degradation of conduit materials due to direct impact with contaminants? ☐ If yes, provide specifications on barrier materials or provide the results of this evaluation in the Vapor Mitigation Plan. Note that if vapor mitigation is planned for site buildings, utility corridors will need to be evaluated as part of mitigation designs: ☒ If no, include rationale here: Results of soil vapor assessment activities completed at the Site indicate that soil vapor encroachment at unacceptable levels for industrial use is not a concern. 20 EMP Version 2, January 2021 ☐ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in the event that evidence of contaminated soil and/or vapors (e.g., unusual odors and/or stained soil) is encountered in utility trenches during redevelopment activities, the trench will be evacuated, and appropriate safety screening of the vapors will be performed to protect workers. If results indicate further action is warranted in response to vapors to protect workers, appropriate engineering controls (such as use of industrial fans) will be implemented. The contractor and workers will observe soil for potential impacts during utility installation activities. Evidence of potentially impacted soil includes a distinct unnatural color, strong odor, or filled or previously disposed materials of concern (i.e., chemicals, tanks, drums, etc.). Should the above be noted during utility work, the contractor will contact the project environmental professional to observe the suspect condition and screen the soil using a PID or other similar vapor field screening instrument. If the project environmental professional confirms that the material may be impacted, then the procedures outlined above in Managing On‐Site Soil (Part 1.A.) will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours to advise that person of the condition. PART 2. GROUNDWATER 1) What is the depth to groundwater at the Brownfields Property? During assessment activities conducted at the Site in March and June 2022, and February 2023, the depth to groundwater was measured at depths ranging from approximately 6 ft bgs in the northwestern portion of the Site to approximately 27 ft bgs in the northeastern portion of the Site. A tabular summary of temporary monitoring well construction details and groundwater depths are provided as Table 2. Locations of the temporary monitoring wells installed during the previous assessment activities are shown in Figure 3. 2) Is groundwater known to be contaminated by ☐onsite ☒offsite ☐both or ☐unknown sources? Describe source(s): Previous groundwater assessment at the Brownfields property included collection of fifteen (15) groundwater samples for laboratory analysis. Locations of the groundwater samples are shown in Figure 3, and a tabular summary of groundwater sample laboratory analytical results is included in Table 3A for traditional compounds and Table 3B for per and polyfluorinated substances (PFAS). Concentrations for traditional compounds are shown in Figure 4A and PFAS concentrations are shown in Figure 4B. A brief summary of the groundwater assessment results is provided below. Volatile and Semi-Volatile Organic Compounds No organic compounds were detected at concentrations above the DEQ 2L Groundwater Quality Standards (2L Standards) or the DEQ Residential or Non-Residential Vapor Intrusion 21 EMP Version 2, January 2021 Groundwater Screening Levels (GWSLs) in groundwater samples collected at the Site. Metals Groundwater assessment results indicate that total chromium (12.7 micrograms per liter {µg/L}) was detected in the central portion of the Site at a concentration slightly above the 2L Standard of 10 µg/L. No other metals were detected in the groundwater samples collected at the Site at concentrations above 2L Standards and/or GWSLs. PFAS In March 2022, groundwater samples were collected for PFAS analysis in temporary monitoring wells TMW-1 and TMW-3 installed in the eastern portion of the Site and downgradient of the east adjacent off-Site Livingstone Coatings facility to evaluate the potential for impact associated with historical coating operations. Additional PFAS groundwater assessment was performed in February 2023, to assist in delineating potential PFAS groundwater impacts in proposed deeper excavation areas of the Site (see Figure 4B). Laboratory analytical results indicate that several PFAS compounds were detected at concentrations above the laboratory method detection limits in groundwater samples collected at the Site. During the March 2022 assessment activities, perfluoroonoctanoic acid (PFOA, 0.3 µg/L) and perfluorooctanesulfonic acid (PFOS, 0.01 µg/L) were detected in the TMW-1 sample at concentrations above the EPA Tapwater Regional Screening Levels (RSLs) of 0.060 µg/L and the EPA Health Advisory Level of 0.000004 µg/L. PFOA (up to 4.8 µg/L) was detected in the TMW-3 groundwater sample and its duplicate groundwater sample at concentrations above the EPA Tapwater RSLs and the EPA Health Advisory Level. During the February 2023 assessment activities, PFOA was detected in TMW-9 (0.558 µg/L), TMW-10/TMW-DUP (up to 0.676 µg/L), and TMW-12 (up to 0.0978), which exceeded the EPA Health Advisory Level, the EPA Tapwater RSL, and the EPA Proposed MCL of 0.004 µg/L. PFOA was also detected in TMW-11 (0.0208 µg/L), TMW-13 (0.0596 µg/L), TMW-14 (0.0065 µg/L), and TMW-15 (0.0141 µg/L), which also exceeded the EPA Health Advisory Level and the EPA Proposed MCL. In addition, PFOS was detected in TMW-13 (0.0042 µg/L) which exceeded the EPA Health Advisory Level of 0.00002 µg/L and the EPA Proposed MCL of 0.004 µg/L. PFOS was also detected in TMW- 9 (0.00094 J [“J-flag” designation] µg/L), TMW-12 (0.0016 J µg/L), TMW-14 (0.0024 J µg/L), and TMW-15 (0.0025 J µg/L) and exceeded the EPA Health Advisory Level. No other PFAS compounds were detected at concentrations above the applicable screening criteria in the groundwater samples collected from the Site. 3) What is the direction of groundwater flow at the Brownfields Property? Groundwater flow at the Site is expected to mimic area topography and generally flow to the west toward an unnamed tributary of Long Creek. 4) Will groundwater likely be encountered during planned redevelopment activities? ☒Yes ☐No If yes, describe these activities: As noted above, the seasonal high water table was measured at depths ranging from 22 EMP Version 2, January 2021 approximately 6 ft bgs in the northwestern portion of the Site to approximately 27 ft bgs in the northeastern portion of the Site. Grading activities may include cut depths up to 30 ft bgs in the central portion of the Site and in areas planned for stormwater retention ponds (see cut-fill analysis in Appendix C). Therefore, groundwater may be encountered during redevelopment activities. If groundwater is encountered during redevelopment activities, the procedures outlined below will be implemented. Regardless of the answer; in the event that contaminated groundwater is encountered during redevelopment activities (even if no is checked above), list activities for contingent management of groundwater (e.g., dewatering of groundwater from excavations or foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or sampling procedures). If groundwater is encountered during redevelopment, appropriate worker safety measures will be undertaken if groundwater gathers in an open excavation within an area determined to be impacted (based on previous sampling data, strong odor, unnatural color, sheen, etc.) during construction activities. The contractor will contact the environmental professional to observe the area(s) suspected to be impacted. The accumulated water will be allowed to evaporate/infiltrate to the extent that the time for dissipation does not disrupt the construction schedule. If work in an area needs to continue and additional time is needed to allow for evaporation/infiltration of the water, the water within an active work zone will be transferred into other portions of the excavation or trench, or to a nearby temporary sediment basin and allowed to naturally dissipate. Water from an active work area may also be temporarily transferred into a frac tank and placed back in the excavation when work in that area has been completed or into a nearby temporary sediment basin to allow for natural dissipation. Should the time needed for the natural dissipation of accumulated water be deemed inadequate, the water will be tested for the presence of PFAS, VOCs, SVOCs, and RCRA metals and disposed of at an appropriate off‐Site facility (if impacted), or tested and pumped to the public stormwater management system (if not impacted above DEQ surface water standards) in accordance with applicable municipal and State regulations for erosion control and construction stormwater control. It should be noted that low levels of PFAS compounds are widely considered to be ubiquitous in the environment and low levels of PFAS detected in water samples collected at the Site during construction that are representative of ubiquitous background conditions will be managed as non-impacted water. In addition, to minimize the potential for groundwater to enter into deeper stormwater ponds, a high-density polyethylene (HDPE) impermeable liner will be installed and sealed within the stormwater ponds located on the eastern portion of the property, closest to the Livingstone facility (TMW-12 and TMW-13). 5) Are monitoring wells currently present on the Brownfields Property?.................☒Yes ☐No If yes, are any monitoring wells routinely monitored through DEQ or other agencies?..................................................................................................................☒Yes ☐No 23 EMP Version 2, January 2021 6) Please check methods to be utilized in the management of known and previously unidentified wells. ☒ Abandonment of site monitoring wells in accordance with all applicable regulations. It is the Brownfields Program’s intent to allow proper abandonment of well(s) as specified in the Brownfields Agreement, except if required for active monitoring through another section of DEQ or the EPA. ☒ Location of existing monitoring wells marked ☒ Existing monitoring wells protected from disturbance ☒ Newly identified monitoring wells will be marked and protected from further disturbance until notification to DEQ Brownfields can be made and approval for abandonment is given. 7) Please provide additional details as needed: Please note, disturbance of existing site monitoring wells without approval by DEQ is not permissible. If monitoring wells are damaged and/or destroyed, DEQ may require that the PD be responsible for replacement of the well. PART 3. SURFACE WATER 1) Is surface water present at the property? ☒ Yes ☐ No ☐ Unknown 2) Attach a map showing the location of surface water at the Brownfields Property. 3) Is surface water at the property known to be contaminated? ☐ Yes ☒ No 4) Will workers or the public be in contact with surface water during planned redevelopment activities? ☒ Yes ☐ No 5) In the event that contaminated surface water is encountered during redevelopment activities, or clean surface water enters open excavations, list activities for management of such events (e.g. flooding, contaminated surface water run‐off, stormwater impacts): Small intermittent unnamed tributaries of Long Creek transect the central and southern portions of the Site. In addition, a pond is located on the northwestern portion of the Site. Although not located on the Brownfields property, a larger perennial unnamed tributary of Long Creek is located along the western Site boundary. The on-Site tributaries and pond effluent discharge to the perennial stream west of the Site. In March and July 2022, a total of five (5) surface water samples were collected at the Site from upstream, mid-stream, and downstream portions of the unnamed tributary of Long Creek, from the unnamed tributary of Long Creek which transects the Existing monitoring wells MW-4 and MW-7 installed as part of ongoing monitoring activities associated with the eastern adjacent Livingstone Coatings Corporation facility are located on the Brownfields property. The PD obtained DEQ IHSB approval to permanently abandon the monitoring wells in an email dated December 8, 2022. A copy of the email approval is provided in Appendix D. DEQ will be notified if newly identified monitoring wells are found on the Brownfields property. 24 EMP Version 2, January 2021 central portion of the Site, and from the influent and effluent sides of a pond located on the northwestern portion of the Site. The results of the March and July 2022 assessment activities did not identify the presence of compounds in the tributaries or the on-Site pond at concentrations above DEQ Surface Water Quality Standards (2B Standards) or In-Stream Target Values. Although not anticipated, if surface water associated with the on-Site tributaries or pond are suspected to be impacted (based on strong odor, unnatural color, sheen, etc.), the contractor will contact the environmental professional to observe the suspect condition. If the environmental professional determines that surface water may be impacted, then appropriate worker safety measures will be undertaken to manage the surface water during construction activities (such that dermal contact can be avoided) and a sample will be collected for laboratory analysis of VOCs, SVOCs, and RCRA metals from the potentially impacted tributary surface water. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours regarding the condition. A tabular summary of the surface water laboratory analytical results is provided in Table 4 and sample locations are shown in Figure 3. PART 4. SEDIMENT 1) Are sediment sources present on the property? ☒ Yes ☐ No 2) If yes, is sediment at the property known to be contaminated: ☐ Yes ☒ No ☐ Unknown 3) Will workers or the public be in contact with sediment during planned redevelopment activities? ☒ Yes ☐ No 4) Attach a map showing location of known contaminated sediment at the property. 5) In the event that contaminated sediment is encountered during redevelopment activities, list activities for management of such events (stream bed disturbance): In March and July 2022, a total of six (6) sediment samples were collected from upstream, mid- stream, and downstream portions of the unnamed tributary of Long Creek, from the unnamed tributary of Long Creek which transects the central portion of the Site, and from the influent and effluent sides of a pond located on the northwestern portion of the Site. The results of the March and July 2022 assessment activities did not indicate the presence of compounds in sediment at the Site at concentrations above PSRGs and background for metals. Although not anticipated, if on- Site sediment is suspected to be impacted (based on strong odor, unnatural color, sheen, etc.), the sediment will be managed in accordance with Part 1.A. above and the DEQ Brownfields project manager will be notified within 48 hours regarding the condition. 25 EMP Version 2, January 2021 A tabular summary of the sediment laboratory analytical results is provided in Table 5 and sample locations are presented on Figure 3. PART 5. SOIL VAPOR 1) Do concentrations of volatile organic compounds at the Brownfields property exceed the following vapor intrusion screening levels (current version) in the following media: IHSB Residential Screening Levels: Soil Vapor:………..☒ Yes ☐ No ☐ Unknown Groundwater:.….☐ Yes ☒ No ☐ Unknown IHSB Industrial/Commercial Screening Levels: Soil Vapor:………..☒ Yes ☐ No ☐ Unknown Groundwater:…..☐ Yes ☒ No ☐ Unknown 2) Attach a map showing the locations of soil vapor contaminants that exceed site screening levels. 3) If applicable, at what depth(s) is soil vapor known to be contaminated? 4) Will workers encounter contaminated soil vapor during planned redevelopment activities? ☐ Yes ☐ No ☒ Unknown In the event that contaminated soil vapor is encountered during redevelopment activities (trenches, manways, basements or other subsurface work,) list activities for management of such contact: The environmental professional will remain on call on an as-needed-basis during redevelopment activities at the Site. If contaminated soil vapors are suspected during redevelopment activities (based on unusual or strong odors, dizziness, lightheadedness, coughing, difficulty breathing, etc.), the excavation area will immediately be evacuated, and the environmental professional will be called to perform appropriate safety screening of the vapors. Safety screening activities include monitoring the worker breathing zone with a calibrated multi-gas monitor (or similar instrument[s] Assessment activities completed in April and June 2022 included collection of twenty-one (21) exterior soil gas samples for laboratory analysis within the footprint of the proposed buildings. Locations of the soil gas samples are shown in Figure 3, and a tabular summary of the laboratory analytical data in comparison to the DEQ Vapor Intrusion Sub-slab and Exterior Soil Gas Screening Levels (SGSLs) is provided in Table 6. In addition, compound concentrations above the DEQ Vapor Intrusion SGSLs are shown in Figure 4C. Results of soil gas sampling identified hexachloro-1,3-butadiene at concentrations above the DEQ Non- Residential Vapor Intrusion SGSLs in at least one sample. No other compounds were detected at concentrations above the Non-Residential SGSLs. Results of hypothetical worst-case scenario risk calculator results for the soil gas to indoor air vapor intrusion pathway indicate the cumulative worst-case risks are orders of magnitude below the acceptable levels for industrial use. Based on these results, there is no indication of a potential vapor intrusion risk at unacceptable levels for the proposed buildings at the Site. 26 EMP Version 2, January 2021 capable of detecting VOCs and combustible gases) for VOCs, methane, oxygen, carbon dioxide, and hydrogen sulfide. If results indicate further action is warranted, appropriate engineering controls (such as use of industrial fans) will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours regarding the condition. PART 6. SUB‐SLAB SOIL VAPOR 1) Do concentrations of volatile organic compounds at the Brownfields property exceed the following vapor intrusion screening levels (current version) in sub-slab soil vapor: IHSB Residential Screening Levels: Soil Vapor:………..☐ Yes ☐ No ☒ Unknown Groundwater:.….☐ Yes ☐ No ☒ Unknown IHSB Industrial/Commercial Screening Levels: Soil Vapor:………..☒ Yes ☐ No ☐ Unknown 2) Groundwater:…..☐ Yes ☒ No ☐ Unknown If data indicate that sub‐slab soil vapor concentrations exceed screening levels, attach a map showing the location of these exceedances. 3) At what depth(s) is sub‐slab soil vapor known to be contaminated? ☐0‐6 inches ☒Other, please describe: No building slabs are present at the Site. However, as noted above, compound concentrations have been detected at concentrations above the Residential and Non-Residential SGSLs in exterior soil gas samples at the Site. 4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment activities? ☐ Yes ☒ No ☐ Unknown ☒ If no, include rationale here: 5) In the event that contaminated soil vapor is encountered during redevelopment activities, list activities for management of such contact No building slabs are present at the Site. The environmental professional will remain on call on an as-needed-basis during redevelopment activities at the Site. If contaminated soil vapors are suspected during redevelopment activities (based on unusual or strong odors, dizziness, lightheadedness, coughing, difficulty breathing, etc.), the excavation area will immediately be evacuated, and the environmental professional will be called to perform appropriate safety screening of the vapors. Safety screening activities include monitoring the worker breathing zone with a calibrated multi-gas monitor (or similar instrument[s] capable of detecting VOCs and combustible gases) for VOCs, methane, oxygen, carbon dioxide, and hydrogen sulfide. If results indicate further action is warranted, appropriate engineering controls (such as use of industrial fans) will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours regarding the condition. 27 EMP Version 2, January 2021 PART 7. INDOOR AIR 1) Are indoor air data available for the Brownfields Property? ☐ Yes ☒ No ☐ Unknown 2) Attach a map showing the location(s) where indoor air contaminants exceed site screening levels. 3) If the structures where indoor air has been documented to exceed risk‐based screening levels will not be demolished as part of redevelopment activities, will workers encounter contaminated indoor air during planned redevelopment activities? ☐ Yes ☐ No ☐ Unknown ☐ If no, include rationale here: Click or tap here to enter text. 4) In the event that contaminated indoor air is encountered during redevelopment activities, list activities for management of such contact: VAPOR INTRUSION MITIGATION SYSTEM Is a vapor intrusion mitigation system (VIMS) proposed for this Brownfields Property? ☐ Yes ☒ No ☐ Unknown ☐ If no or unknown, include rationale here as well as plans for pre-occupancy sampling, as necessary: Based on the results of previous assessment activities conducted at the Site (which included the collection of soil, groundwater, and soil vapor samples for laboratory analysis), cumulative risk calculations indicate that potential carcinogenic and non-carcinogenic risks associated with the detections are within the range of acceptable limits for non-residential use. Therefore, vapor mitigation controls are not warranted at the Site. If yes, ☐ VIMS Plan Attached or ☐ VIMS Plan to be submitted separately If submitted separately provide date: Click or tap here to enter text. VIMS Plan shall be signed and sealed by a NC Professional Engineer If no, please provide a brief rationale as to why no vapor mitigation plan is warranted: As described above, results of assessment activities completed at the Site indicate that there is no unacceptable vapor intrusion risk for industrial use at the Site. In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors are identified or workers report lightheadedness or other unusual physical reaction), during future redevelopment activities, the area will be evacuated, and appropriate safety screening of the indoor air will be performed. If warranted, safety screening procedures will include periodically screening indoor air for volatile organic vapors with a calibrated PID. If the results indicate further action is warranted, appropriate engineering controls (such as the use of industrial fans) will be implemented. 28 EMP Version 2, January 2021 Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land use restrictions or requirements of the recorded or draft Brownfields Agreement and that separate approval of mitigation measures will be required. CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials In this section please provide actions that will be taken to identify or manage unknown potential new sources of contamination. During redevelopment activities, it is not uncommon that unknown tanks, drums, fuel lines, landfills, or other waste materials are encountered. Notification to DEQ Brownfields Project Manager, UST Section, Fire Department, and/or other officials, as necessary and appropriate, is required when new potential source(s) of contamination are discovered. These Notification Requirements were outlined on Page 1 of this EMP. Should potentially impacted materials be identified that are inconsistent with known site impacts, the DEQ Brownfields Project Manager will be notified, and a sampling plan will be prepared based on the EMP requirements and site-specific factors. Samples will generally be collected to document the location of the potential impacts. Check the following chemical analysis that are to be conducted on newly identified releases: ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver) EPA Methods 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text. ☒ Other Constituents & Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.) Please note, if field observations indicate the need for additional analyses, they should be conducted, even if not listed here. Hexavalent Chromium by EPA Methods 7199 Please provide details on the proposed methods of managing the following commonly encountered issues during redevelopment of Brownfields Properties. During construction activities, contractors may encounter unknown subsurface environmental conditions (i.e., tanks, drums, or waste materials) that if encountered, will require management. Prior to beginning Site work, H&H will attend a pre-construction kick-off meeting with the PD and the redevelopment contractors to discuss the DEQ-approved EMP and various scenarios when it would 29 EMP Version 2, January 2021 be appropriate and necessary to notify H&H of the discovery of unknown subsurface features or potentially impacted media at the Site. In the event that such conditions are encountered during Site development activities, the information provided below will be used to direct environmental actions to be taken during these activities and sampling data for potentially impacted soil and the disposition of impacted soil will be provided to DEQ when the data becomes available. Underground Storage Tanks: In the event a UST or impacts associated with a UST release are discovered at the Site during redevelopment activities, the UST and/or UST-related impacts will be addressed through the Brownfields Program. DEQ Brownfields will be notified within 48 hours of the discovery of the UST. If an undocumented UST is encountered, residual fluids (if present) will be removed, sampled for VOCs, SVOCs, and RCRA metals, and transported off-Site for disposal at a suitable facility based on the laboratory analytical results. Following the removal of residual fluids, the tank will be removed and closure soil sampling will be performed. The number of soil samples will be consistent with DEQ UST Section guidelines. The soil samples will be submitted for laboratory analysis of VOCs, SVOCs, and RCRA metals. Impacted soil will be managed in accordance with the procedures described in the Managing On-Site Soil (Part 1.A.) section outlined above. If the UST cannot be removed for geotechnical or construction purposes, DEQ will be notified for approval of in-place closure. Following DEQ approval, closure soil sampling will be performed in general accordance with the DEQ UST Section guidelines. Where appropriate, the bottom of the UST may be penetrated before abandonment to prevent fluid accumulation. If the UST contains residual fluids, the fluids will be removed, sampled for VOCs, SVOCs, and RCRA metals, and transported off- Site for disposal at a suitable facility based on the laboratory analytical results. Sub-Grade Feature/Pit: If a sub-grade feature or pit is encountered and does not require removal for geotechnical or construction purposes, it will be filled with soil or suitable fill and construction will proceed. Where appropriate, the bottom may be penetrated before backfilling to prevent fluid accumulation. If the pit contains waste, the material will be set aside in a secure area and will be sampled for waste characterization purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and disposed off-Site at a permitted facility or the waste will be managed in accordance with the Managing On-Site Soil section outlined above in the EMP, whichever is most applicable based on the type of waste present. If the pit must be removed and the observed waste characteristics indicate the concrete may potentially be contaminated to a significant degree, the concrete will be sampled and analyzed by methods specified by the disposal facility. Buried Waste Material – Note that if buried waste, non-native fill, or any obviously filled materials is encountered, the DEQ Brownfields Program must be notified to determine if investigation of landfill gases is required: 30 EMP Version 2, January 2021 If excavation into buried wastes or significantly impacted soil occurs, the contractor is instructed to stop work in that location and notify Hart & Hickman. Hart & Hickman will observe the suspect materials and collect samples for laboratory analysis if warranted. Confirmation sampling will be conducted at representative locations in the base and the sidewalls of the excavation after the waste or significantly impacted soil is removed. The confirmation samples will be analyzed for VOCs, SVOCs, and RCRA metals (or other analyses as appropriate based on the type of waste material). Information will be provided to DEQ Brownfields regarding the permitted facility used for disposal of the waste or significantly impacted soil. Areas of suspected contaminated soil that remain at the Site after excavation is complete above the DEQ Industrial/Commercial PSRGs will be managed pursuant to this plan. Re-Use of Impacted Soils On-Site: Please refer to the description outlined in the Managing On-Site Soil section (Part 1.A.) of the EMP above. If unknown, impacted soil is identified on-site, management on-site can be considered after the project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields Project Manager approval prior to final placement on-site. If other potential contingency plans are pertinent, please provide other details or scenarios as needed below: Click or tap here to enter text. POST‐REDEVELOPMENT REPORTING ☒ Check this box to acknowledge that a Redevelopment Summary Report will be required for the project. If the project duration is longer than one year, an annual update is required and will be due by January 31 of each year, or 30 days after each one-year anniversary of the effective date of this EMP (as agreed upon with the Project Manager). These reports will be required for as long as physical redevelopment of the Brownfields Property continues, except that the final Redevelopment Summary Report will be submitted within 90 days after completion of redevelopment. Based on the estimated construction schedule, the first Redevelopment Summary Report is anticipated to be submitted on 1/31/2024 The Redevelopment Summary Report shall include environment-related activities since the last report, with a summary and drawings, that describes: 1. actions taken on the Brownfields Property; 2. soil grading and cut and fill actions; 3. methodology(ies) employed for field screening, sampling and laboratory analysis of environmental media; 4. stockpiling, containerizing, decontaminating, treating, handling, laboratory analysis and 31 EMP Version 2, January 2021 ultimate disposition of any soil, groundwater or other materials suspected or confirmed to be contaminated with regulated substances; and 5. removal of any contaminated soil, water or other contaminated materials (for example, concrete, demolition debris) from the Brownfields Property (copies of all legally required manifests shall be included). ☒ Check box to acknowledge consent to provide a NC licensed P.G. or P.E. sealed, Redevelopment Summary Report in compliance with the site’s Brownfields Agreement. 06/02/2023 33 EMP Version 2, January 2021 Tables Table 1 Summary of Soil Analytical DataRhyne Road AssemblageCharlotte, North CarolinaH&H Job No. BCP-180Evaluation AreaSample IDCOMP-3DateDepth (ft bgs)Sample Type Range Range UnitsVOCs (8260D)Bromomethane0.0142 J, C7,v3 0.0156 C7,v3 0.0143 C7,v3 0.0172 C7,v3<16.1<12.4<21.7<12.0<13.21.46.4----2-Butanone (MEK)<35.6<32.2<23.9<33.90.0538 J C7, v3 0.0415 J C7, v3 0.0449 J C7, v3 0.0381 J C7, v3 0.0673 J C7, v35,50040,000----Xylene (Total)<4.2<3.8<2.8<4.00.0102 J0.0051 J0.0074 J0.0054 J0.0125 J120530----o-Xylene<3.3<3.0<2.2<3.10.01020.0051 J0.0074 J0.0054 J0.0125 J140590----SVOCs (8270E)bis(2-Ethylhexyl)phthalate0.578<0.164<1.47<0.146<139<172<178<159<16339160----Metals (6020B/7471B/7199)Arsenic0.51 J 0.84 1.5 1.4 0.92 1.0 1.1 0.77 0.71 0.68 3.0 1.4 - 2.9 1.0 - 18Barium87.189.611580.231224110815399.53,10047,00049.6 - 71.050 - 1,000Cadmium<0.039<0.0390.0970.035 J<0.0370.049 J <0.039<0.039<0.0421.420<0.039 - <0.0421.0 - 10Chromium (total)17.222.072.641.161.534.327.615.284.1NENE30.0 - 77.07.0 - 300Chromium (VI)0.539 J1.18 J1.682.251.05 J0.544 J0.381 J1.03 J2.350.316.51.68 - 2.89NSChromium (III)16.6620.8270.9038.8560.4533.7627.2214.1781.7523,000350,00028.32 - 74.11NSLead1.62.64.93.62.21.12.72.21.44008001.9 - 6.8ND - 50Mercury<0.011<0.010<0.00990.0460.0420.019 J 0.0240.011 J0.013 J4.7700.015 - 0.0500.03 - 0.52Selenium0.11 J0.23 J0.39 J0.38 J0.27 J0.17 J0.36 J0.22 J0.17 J781,2000.45 - 0.88<0.1 - 0.8Silver<0.18<0.18<0.16<0.15<0.17<0.17<0.18<0.18<0.19781,200<0.18 - 0.21ND - 5.0 Notes:1) North Carolina Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) dated July 2022.2) Range values of background metals for North Carolina soils taken from Elements in North American Soils by Dragun and Chekiri, 2005; Cd and Ag concentrations were taken from Southeastern and Conterminous U.S. Soils.Soil concentrations are reported in milligrams per kilogram (mg/kg).Compound concentrations are reported to the laboratory method detection limits.Laboratory analytical methods are shown in parentheses.With the exception of metals, only constituents detected in at least one sample are shown in the table above.VOCs = volatile organic compounds; SVOCs = semi-volatile organic compounds; ft bgs= feet below ground surfaceNS = not specified; NE = not established; -- = not applicableC7 = Compound may be laboratory conaminant (not present in method blank).v3 = The continuing calibration was below method acceptance limit.J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.

Appendix B Preliminary Construction Schedule Appendix C Preliminary Grading Plan and Cut/Fill Analysis Appendix D Monitoring Well Abandonment Approval From:Adams, George To:Ralph McGee Cc:Day, Collin; Caldwell, Shawna; Morris, Brett L. Subject:RE: [External] Livingstone Coatings (NONCD0002012) - monitoring well abandonment Mecklenburg Date:Thursday, December 8, 2022 3:26:12 PM Attachments:image005.png Ralph,   If a groundwater monitor well is damaged or threatened with damage, I believe it needs to be abandoned.  There are specific rules in 15A NCAC 2C that the DWR enforces (Andrew Pitner); however, it’s not entirely clear to me which party owns the well after a real estate transaction.    To my knowledge, remedial activities at Livingstone Coating paused in 2012.  I think another party contacted me several times about pursuing a risk-based closure (~2018).  Perhaps your client could agree to replace the wells if remedial activities resume?    Thank you for contacting me and let me know if you need more information.  Please send me and DWR copies of the monitor well abandonment forms for our records --George   George Adams (he/him/his) Engineer, Division of Waste Management North Carolina Department of Environmental Quality Office: (704) 663-1699 ext. 2187 | Fax: (704) 663-6040 |Cell: (984) 232-1130 (Temporary) george.adams@ncdenr.gov   From: Ralph McGee <RMcGee@harthickman.com>  Sent: Thursday, December 8, 2022 1:02 PM To: Adams, George <george.adams@ncdenr.gov> Subject: [External] Livingstone Coatings (NONCD0002012) - monitoring well abandonment   CAUTION: External email. Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to Report Spam.   George,   Thanks so much for taking my call. As discussed, properties adjacent to the west and south of the Livingstone Coatings facility are planned for redevelopment and Livingstone monitoring wells MW-4 and MW-7 (see attached) will need to be abandoned prior to disturbance/grading.  Per our call, if these wells need to be replaced in the future, there are suitable very nearby replacement locations within the Livingstone property boundaries.   Can you please confirm that DEQ agrees the wells will need to be abandoned prior to damage and that if replacement is needed, there are locations within the Livingstone property boundaries that are suitable for your assessment/monitoring purposes?   Thanks so much!
