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.

PART 1. Soil 1) Known or suspected contaminants in soil (list general groups of contaminants): Eleven (11) soil samples were collected in northwestern and south‐central portions of the Brownfields property in April 2021 during Brownfields Assessment activities completed to evaluate the potential for impacts associated with a former on‐Site underground storage tank (UST) and, former paint storage area, and in‐situ soil characterization soil samples were collected in areas proposed for cut that will generate excess soil during grading that cannot be re‐used on‐ Site. In addition, two (2) composite soil samples and two (2) grab samples (CS‐05/CS05A and CS‐ 06/CS‐06A) were collected from a soil stockpile located in the eastern portion of the Site by Terracon Consultants, Inc. in October 2018. A tabular summary of the soil analytical data collected in 2018 is provided in Appendix C, and the soil sample locations are depicted in Figure 2. A tabular summary of soil analytical data collected in April 2021 in comparison to the June 2021 North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) is included as Table 1. The April 2021 UST and paint storage related soil sample locations are shown in Figure 3, and in‐situ soil sample locations are shown in Figure 5. Compound concentrations exceeding PSRGs during the April 2021 sampling event are shown in Figure 4 and Figure 5. A brief summary of the results is provided below: Volatile Organic Compounds Low levels of toluene (up to 0.0051 J milligrams per kilogram [mg/kg]) were detected in soil samples SB‐3 (0‐2 ft), EX‐2 (0‐2 ft), EX‐3 (4‐5 ft) and EX‐5 (0‐2 ft), but at concentrations below the DEQ IHSB Residential PSRGs. The “J” flag designation indicates the compound was detected at a concentration above the laboratory method detection limits but below the laboratory reporting limits, resulting in a laboratory estimated concentration. In addition, low levels of n‐ butylbenzene (0.0074 mg/kg), ethylbenzene (0.0043 J mg/kg), naphthalene (0.0191 J mg/kg), 1,2,4‐trimethylbenene (0.0169 mg/kg), m&p‐xylene (0.0114 J mg/kg), and o‐xylene (0.0057 J mg/kg) were detected in soil sample EX‐3 (4‐5 ft), but at concentrations below the DEQ IHSB Residential PSRGs. Low levels of the VOCs chloroform (0.0021 J mg/kg) and naphthalene (0.0032 J mg/kg) in soil sample CS‐05A at concentrations well below the DEQ IHSB PSRGs. No other VOCs were detected at concentrations above laboratory method detection limits in the soil samples collected at the Site. Semi‐Volatile Organic Compounds Laboratory analytical results indicated the presence of the polycyclic aromatic hydrocarbon 9 EMP Version 2, January 2021 (PAH) benzo(a)pyrene (0.141 J mg/kg) in sample EX‐1 (0‐5 ft) slightly above the IHSB Residential PSRG of 0.11 mg/kg. The PAHs benzo(a)anthracene (1.43 mg/kg), benzo(a)pyrene (1.23 mg/kg), benzo(b)fluoranthene (1.45 mg/kg), and dibenzo(a,h)anthracene (0.251 J mg/kg) were detected in sample CS‐06, collected from the soil stockpile in the eastern portion of the Site, at concentrations above the DEQ IHSB Residential PSRGs. Sample EX‐1 (0‐5 ft) also contained concentrations of benzo(a)anthracene (0.178 mg/kg), benzo(b)fluoranthene (0.203 J mg/kg), fluoranthene (0.310 J mg/kg), phenanthrene (0.181 J mg/kg) and pyrene (0.283 J mg/kg), all below the DEQ IHSB Residential PSRGs. Stockpile sample CS‐06 also contained concentrations of acenaphthene (0.886 mg/kg), anthracene (0.823 mg/kg), benzo(k)fluoranthene (0.631 mg/kg), benzo(g,h,i)perylene (0.711 mg/kg), chrysene (1.12 mg/kg), dibenzofuran (0.318 J mg/kg), fluoranthene (2.89 mg/kg), fluorene (0.5 mg/kg), ideno(1,2,3‐ cd)pyrene (0.697 mg/kg), 2‐methylnaphthalene (0.132 J mg/kg), naphthalene (0.526 mg/kg), phenanthrene (3.07 mg/kg) and pyrene (2.43 mg/kg), all below the DEQ IHSB Residential PSRGs. The PAH fluoranthene (0.320 J mg/kg) was detected in soil samples CS‐05 at a concentration well below the DEQ Residential PSRG of 480 mg/kg. No other SVOCs were detected above laboratory method detection limits in any other samples collected at the Site. Metals Laboratory analytical results indicate that several metals were detected at concentrations above the laboratory method detection limits. The metal arsenic (up to 7.19 mg/kg) was detected in each soil sample at a concentration above the DEQ IHSB Residential PSRG of 0.68 mg/kg, but the results are consistent with published background concentrations for North Carolina soils and are considered naturally occurring. Hexavalent chromium (up to 2.04 mg/kg) was detected at a concentration above the DEQ IHSB Residential PSRG of 0.31 mg/kg and above naturally occurring background levels in deeper soil sample SB‐1 (8‐10 ft). Elevated hexavalent chromium concentrations are limited to deeper soil in the vicinity of the former UST basin and are not considered widespread in Site soil based on results of soil assessment activities. Additional metals, including barium, trivalent chromium, lead, mercury, and selenium, were detected in soil samples collected at the Site at concentrations consistent with background data for the Site area and published background levels for North Carolina soils. 2) Depth of known or suspected contaminants (feet): As noted above, benzo(a)pyrene and hexavalent chromium were detected at concentrations above the DEQ IHSB PSRGs in shallow soil sample EX‐1 (0‐5 ft) and deeper soil sample EX‐1 (8‐10 ft bgs), respectively. In addition, several PAHs are present at levels above PSRGs in northeastern portion of a soil stockpile staged in the eastern portion of the Site. 3) Area of soil disturbed by redevelopment (square feet): Based on the preliminary grading plans and cut‐fill analysis (Appendix B), the entire Site is 10 EMP Version 2, January 2021 expected to be cleared and graded (approximately 154,000 square feet) to level the Site for redevelopment. A copy of the preliminary grading plan and cut‐fill analysis is provided as Appendix B. 4) Depths of soil to be excavated (feet): Based on review of the cut‐fill analysis, planned cut depths are expected to range from approximately 1 to 8 ft bgs in in the vicinity of the proposed apartment complex and multi‐story open‐air parking deck. Other discrete areas may include deeper excavations for installation of deeper foundational footers, elevator banks, utility banks, etc. Remaining portions of the Site are planned for fill to achieve final grade elevations. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Cut‐fill analysis and calculations indicate that the total volume of soil to be excavated and/or cut is approximately 7,400 cubic yards. In addition, limited excavations for installation of new utilities will be completed during redevelopment of the Site. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Based on a review of the preliminary grading plan and soil sample analytical results, less than 2,000 cubic yards of excavated soil is anticipated to be impacted by contaminants. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Based on review of the grading plan and cut‐fill analysis, up to 7,400 cubic yards of excess soil may need to be transported off‐Site. Soil samples collected within in‐situ soil characterization section EX‐1 located in the northern portion of the Site identified benzo(a)pyrene (0.141 J mg/kg) at a concentration slightly above the DEQ IHSB Residential PSRG. No other compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in the case of metals in areas of planned cut that will generate excess soil. Based on review of the grading plan and cut‐fill analysis, up to 2,000 cubic yards of stockpiled soils may need to be transported off‐Site. Soil samples collected from the eastern portion of the stockpile contained benzo(a)anthracene (1.43 mg/kg), benzo(a)pyrene (1.23 mg/kg), benzo(b)fluoranthene (1.45 mg/kg), and dibenzo(a,h)anthracene (0.251 J mg/kg) at concentrations above the DEQ IHSB Residential PSRGs. No other compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in the case of metals (see Appendix C) in the stockpiled soils. DEQ Brownfields provided export approval options for the soil stockpile in a letter dated October 31, 2018. A copy of the DEQ provided Brownfields Soil Management Options letter is included in Appendix D for ease of reference. If potentially impacted soil is encountered and cannot be reused on‐Site 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 11 EMP Version 2, January 2021 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).

However, the grading contractor will take into account conditions such as wind speed, wind direction, and moisture content of soil during soil grading and stockpiling activities to minimize dust generation. 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). ☐ 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 and/or contractors will observe soils for evidence of potential significantly impacted soil. Evidence of potential impacted soil includes a distinct unnatural color, strong odor, or filled or previously disposed materials of concerns (i.e., chemicals, tanks, drums, etc.). Should the above be noted during Site work, the contractor will contact the project environmental engineer to observe the suspect condition. If the project environmental engineer confirms that the material may be impacted, then the procedures below will be implemented. In addition, the environmental engineer will contact the DEQ Brownfields project manager within 48‐hours to advise that 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: Collection of additional soil samples is not anticipated based on results of previous Site assessment activities. If previously unknown significant soil impact is encountered during grading and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading and/or construction of the utility to continue and/or only as far as needed to allow alternate corrective measures described below. Suspect impacted soil excavated during grading and/or utility line installation or removal 14 EMP Version 2, January 2021 may be stockpiled and covered in a secure area to allow construction to progress. Suspect impacted soil will be underlain by and covered with minimum 10‐mil plastic sheeting. At least one representative soil sample (no less than 3 aliquot soil samples) at a sample ratio of 1 soil sample per every approximately 1,000 cubic yards of soil will be collected for the analyses selected below (i.e., total VOCs, SVOCs, and RCRA metals plus 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 upon the laboratory analyses: i. If no organic compounds are detected in a sample (other than which are attributable to sampling or laboratory artifacts) and metals are below the Protection of Groundwater or Residential PSRG (whichever is lower for the detected compounds) and are consistent with Site‐specific background levels with acceptable cumulative risk calculator results, then the soil will be deemed suitable for use as on‐Site fill or as off‐Site fill. The proposed location(s) for off‐Site placement of soil (other than a permitted facility) along with the receiving facility’s written approval for acceptance of the soil 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 the DEQ IHSB Residential PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with Site‐specific background levels for metals), the TCLP concentrations are below hazardous waste criteria, and cumulative risk calculator results are acceptable, then the soil may be used on‐Site as fill without conditions. iii. If detectable levels of compounds are found which exceed the DEQ IHSB Residential PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with background levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil, with DEQ written approval, may be used on‐Site as fill below an impervious surface, or at least 2 ft of documented compacted clean soil. If the impacted soil with concentrations above Residential PSRGs is moved to an on‐Site location, its location and depth will be documented, and its location will be provided to DEQ iv. Impacted soil may be transported to a Brownfields approved permitted facility such as a landfill or landfarm provided that the soil is accepted at the disposal facility. If soil is transported to a permitted facility, the permitted facility’s written approval or acceptance to dispose of soil from the Site will be included with the final redevelopment 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 permitted disposal facility that can accept or treat hazardous waste. *Please note that should the PD elect to transport export soil to a permitted facility or to a DEQ Brownfields pre‐approved receiving facility, soil will be direct loaded onto trucks for transport off‐Site.

Part 1.B. IMPORTED FILL SOIL NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL FROM THE BROWNFIELDS PROGRAM. 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 2) If yes, what is the estimated volume of fill soil to be imported? Based on conversations with the PD and the available grading plans, approximately 6,800 cubic yards of fill will need to be imported to the Site 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 northern and eastern portions of the Site (Appendix B). The thickness of the fill ranges from approximately 1 ft to 14 ft. 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: For import soil needed during grading activities, the procedures outlined in Part 1.B. Section 7 below will be followed to demonstrate import soil meets acceptable standards applicable to the Site. 17 EMP Version 2, January 2021 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 limited amounts of lime or cement as an amending agent for drying soil as needed during grading and redevelopment activities. The PD does not plan to collect samples of lime or concrete used as an amending agent prior to use at the Site. For import soil needed during grading activities, the procedures outlined in Part 1.B. Section 7 below will be followed to demonstrate import soil meets 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 Method 7199 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 necessary. 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. 18 EMP Version 2, January 2021 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, a sampling plan will be developed and submitted for DEQ review. DEQ approval of the sampling plan and analytical results will be obtained prior to transporting import soil to the Site. The specific sampling rate will be outlined in the aforementioned sampling plan. However, if the proposed borrow source has not been previously developed (i.e., virgin land), soil samples will be collected for laboratory analyses indicated above at a general rate of one per 1,000 cubic yards which will contain 3‐5 composite aliquot locations and one grab location. If the proposed borrow source is a permitted quarry that has not been pre‐approved by DEQ Brownfields (e.g., Martin Marietta quarry located on Arrowood Road in Charlotte, NC), one composite soil sample consisting of 3‐5 composite aliquot locations and one grab location will be collected for the laboratory analyses indicated above. Fill soil will be considered suitable for use at the Site if it does not contain compound concentrations above DEQ IHSB Residential PSRGs, DWM Risk Calculator risk thresholds, or typical metals concentrations which are consistent with levels identified 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. Based on review of the grading plan and cut‐fill analysis, up to approximately 7,400 cubic yards of geotechnically unsuitable soil and up to approximately 2,000 cubic yards of stockpiled soil may need to be transported off‐Site. The soil stockpile may be transported off‐Site in accordance with the Brownfields Soil Management Options letter provided by DEQ on October 31, 2018 or may be reused in fill areas of the Site during redevelopment activities. H&H completed in‐situ soil sampling in areas of planned cut where excess soil will be generated that cannot be re‐used on‐Site as fill due to geotechnical conditions. In situ soil characterization sampling was completed in accordance with the DEQ‐approved Brownfields Assessment Work Plan dated April 6, 2021. The assessment included collection of seven (7) soil samples (EX‐1 19 EMP Version 2, January 2021 through EX‐7) for laboratory analysis to identify areas of planned cut at the Site that do not have compound concentrations in soil above DEQ IHSB Protection of Groundwater or Residential PSRGs (whichever is lower) so that soil can be direct loaded onto trucks and transported off‐Site during grading activities. In‐situ soil sampling results identified benzo(a)pyrene (0.141 J mg/kg) at a concentration slightly above the DEQ IHSB Residential PSRG in soil characterization section EX‐1 located in the northern portion of the Site (Figure 5). No other compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in the case of metals in the EX‐1 soil characterization section. No compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in the case of metals in the other in situ soil characterization sections (EX‐2 through EX‐7). The locations of in situ soil samples and in situ soil characterization sections are shown with an overlay of the cut/fill analysis map in Figure 5, and a tabular summary of the in situ soil sample analytical results is included as Table 1. Export soil generated during grading within in situ soil characterization section EX‐1 will be re‐ used on‐Site as fill (if possible), transported to a Municipal Solid Waste landfill such as the Republic Services facility in Concord, NC, or with DEQ prior written approval, to another Brownfields property in need of import soil. Written approval from the receiving facility will be obtained and provided to DEQ prior to transporting the soil off‐Site. Export soil generated during grading within in situ soil characterization sections EX‐2 through EX‐7 will be direct loaded and transported to the Reeves Land Clearing and Inert Debris (LCID) Landfill or to the Old 27 LCID Landfill, or with DEQ prior written approval, other LCID and Construction & Demolition (C&D) landfills with similar background metals concentrations, or to other Brownfields property(s) in need of import soil. A tabular summary of metals concentrations detected in soil characterization sections EX‐2 through EX‐7 in comparison to background metals concentrations detected in soil samples collected at the Reeves and Old 27 LCID landfill facilities is provided in Appendix E. The laboratory analytical reports and chain of custody records for background soil samples collected at the Reeves and Old 27 LCID landfill facilities are also provided in Appendix E. Should additional export be required outside of the in situ soil characterization sections, the following sampling plan will be implemented. Prior to transporting the soil off‐Site, a sampling plan will be developed and submitted to DEQ Brownfields for review and approval. Generally, soil samples will be collected from export soil at a rate of one sample per every 1,000 cubic yards of export material which will include a minimum of three combined composite locations and one grab location. Export soil sampling may be conducted in‐situ prior to the onset of grading and an In Situ Soil Characterization Assessment Work Plan will be provided to DEQ for review and approval. DEQ approval of the sampling plan, sampling locations, and analytical results will be obtained 20 EMP Version 2, January 2021 prior to transporting the additional export soil from the Site. Based on 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, DEQ Brownfields approval and written approval from the receiving facility 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 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 noted above, prior to exporting additional soil not characterized as part of in situ soil sampling completed in April 2021 and described above, the environmental engineer will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ Solid Waste approval prior to exporting soil to a non‐Brownfields property or non‐permitted disposal facility. 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? 21 EMP Version 2, January 2021 ☐ 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: Click or tap here to enter text. ☒ If no, include rationale here: Results of soil gas assessment activities completed within the footprint of the proposed apartment and office buildings indicate that no compounds are present at concentrations that pose unacceptable vapor intrusion risks on the Brownfields property. However, chlorinated solvent impacts were discovered in groundwater in the northern portion of the Site. Note that the PD plans to install a passive vapor intrusion mitigation system during construction of the apartment and office buildings. ☐ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings Other comments regarding managing impacted soil in utility trenches: The contractor and workers will observe soil for potential impacts during utility installation activities. Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or filled or previously disposed materials of concerns (i.e., chemicals, tanks, drums, etc.). Should the above be noted during utility work, the contractor will contact the project environmental engineer to observe the suspect condition. If the project environmental engineer confirms that the material may be impacted, then the procedures outlined in Managing On‐Site Soil above will be implemented. In addition, the environmental engineer will contact the DEQ Brownfields project manager within 48‐ hours to advise that person of the condition. Should impacted soil be discovered during utility trenching activities, appropriate safety screening will be performed to protect workers during utility installation activities. Safety screening activities include monitoring the worker breathing zone with a calibrated photoionization detector or similar instrument at all times when in utility trenches. If safety screening results indicate further action is warranted, the work zone will be evacuated until appropriate engineering controls (such as use of industrial fans) are implemented. PART 2. GROUNDWATER 1) What is the depth to groundwater at the Brownfields Property? During groundwater assessment activities completed in April 2021, the depth to groundwater was measured at a depth ranging from approximately 10 ft bgs in lower lying areas in the northern portion of the Brownfields property to approximately 19 ft bgs at higher elevations located in the western portions of the Brownfields property. 2) Is groundwater known to be contaminated by ☐onsite ☐offsite ☒both or ☐unknown sources? Describe source(s): Historical groundwater assessment at the Brownfields property included collection of seventeen (17) groundwater samples for laboratory analysis. Recent groundwater assessment at the 22 EMP Version 2, January 2021 Brownfields property included collection of two (2) groundwater samples for laboratory analysis. In addition, nine (9) monitoring wells were installed and sampled in the eastern portion of the Site at the former Gay Laundry and Cleaners facility (1101 N. Brevard Street) on behalf of the Dry‐cleaning Solvent Cleanup Act (DSCA) Program. Locations of select historical groundwater samples are shown in Figure 2 and locations of recent groundwater samples are shown in Figure 3. A tabular summary of recent groundwater sample laboratory analytical results is included as Table 2. Historical groundwater analytical data is provided as Appendix C. Compound concentrations exceeding DEQ NCAC 15A 2L Groundwater Quality Standards (2L Standards) and/or the DEQ Division of Waste Management (DWM) Vapor Intrusion Groundwater Screening Levels (GWSLs) during the most recent sampling event are shown in Figure 4. A brief summary of the groundwater assessment results is provided below. Volatile Organic Compounds Groundwater sample results indicate that tetrachloroethylene (PCE) was detected in groundwater in the western and northern portions of the Site at concentrations ranging from 0.72 micrograms per liter (µg/L) to 35 µg/L, which exceed the 2L Standard of 0.7 µg/L and/or the DEQ DWM Vapor Intrusion Residential and Non‐Residential GWSLs of 12 µg/L and 48 µg/L, respectively. The chlorinated compound trichloroethylene (TCE) was also detected in groundwater samples collected in the northern and western portions of the Site at concentrations ranging from 3.5 µg/L in the western portion of the Site (SLGW‐9) to 37 µg/L in the northern portion of the Site (SLGW‐16), which exceed the 2L Standard of 3 µg/L and the DEQ DMW Residential and/or Non‐Residential Vapor Intrusion GWSLs of 1.0 µg/L and 4.4 µg/L. The VOC chloroform (up to 3.8 µg/L) was also detected in a groundwater sample collected in the eastern portion of the Site (GW‐07) at a concentration above the DEQ DWM Residential and Non‐Residential GWSLs of 0.81 µg/L and 3.6 µg/L, respectively. The chlorinated solvents PCE and TCE were also detected in the eastern portion of the Site (1101 N. Brevard Street) during assessment activities performed under the preview of the DSCA Program. During the most recent groundwater monitoring event in 2009, PCE (up to 1.8 µg/L) was detected at concentrations above the 2L Standard in monitoring wells (MW‐2, MW‐3, and MW‐4) installed downgradient of the former Gay Laundry facility. TCE (up to 0.70 J µg/L) was also detected in groundwater samples collected downgradient of the former Gay Laundry facility, but at concentrations below the 2L Standard. Note that the release incident associated with the former Gay Laundry facility was issued a No Further Action letter by the DSCA Program on August 30, 2010 after analytical data and statistical analysis indicated that the solvent plume was stable to decreasing and vapor intrusion risks were below the unacceptable threshold criteria. The VOCs acetone, benzene, 2‐butanone, chlorobenzene, 1,1‐dichloroethene, 1,2‐ dichlorobenzene, cis‐1,2‐dichloroethene, 1,2‐dichloropropane, ethylbenzene,4‐methyl‐2‐ pentanone, 2‐hexanone, styrene, toluene, and xylenes were also detected in groundwater samples collected at the Site at concentrations above the laboratory method detection limits, but well below the 2L Standards and the DEQ DWM Vapor Intrusion GWSLs. No other organic compounds were detected in Site groundwater at concentrations above the laboratory method detection limits. Semi‐Volatile Organic Compounds No SVOCs were detected at concentrations above the laboratory method detection limits in 23 EMP Version 2, January 2021 groundwater samples collected at the Brownfields property. Metals During assessment activities conducted in 2001 and 2016, groundwater sample results indicate that arsenic (up to 14.7 µg/L) and cadmium (up to 17 µg/L) were detected in groundwater at the Site at concentrations above the 2L Standards of 10 µg/L and 2 µg/L. Groundwater analytical results also indicate that chromium (up to 282 µg/L), lead (up to 74.6 µg/L), and selenium (up to 27 µg/L) were detected at concentrations above the 2L Standards of 10 µg/L, 15 µg/L, and 20 µg/L, respectively. It is of note that the environmental reports prepared for the Site attribute the elevated metals concentrations to high turbidity in the groundwater samples collected in 2001 and 2016. Filtered groundwater samples collected at the Site in November 2016 and the most recent groundwater sampling data (unfiltered samples) did not detect dissolved metals concentrations above the 2L Standards. 3) What is the direction of groundwater flow at the Brownfields Property? Shallow groundwater is expected to mimic surface topography which slopes generally northwest and northeast toward a tributary of Little Sugar Creek generally located along the northwestern and northeastern Site boundaries (Figure 1). 4) Will groundwater likely be encountered during planned redevelopment activities? ☐Yes ☒No If yes, describe these activities: Shallow groundwater was encountered approximately 10 to 19 ft bgs during recent groundwater assessment activities conducted at the Brownfields property. Grading activities are expected to result in a net import at the Site and will not result in decreased surface elevations in areas were shallow groundwater may be encountered. Proposed fill depths range from 1 to 10 ft. The deepest trenches for utility installations are proposed for 5 ft bgs following grading. Therefore, encountering groundwater during redevelopment activities is not anticipated at this time. 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). Appropriate worker safety measures will be undertaken if groundwater gathers in an open excavation within an area determined to be impacted during construction activities. The accumulated water will be allowed to evaporate/infiltrate to the extent time for dissipation does not disrupt the construction schedule. Should the time needed for natural dissipation of accumulated water be deemed inadequate, an environmental professional will be contacted and the water will be tested and disposed off‐Site (if impacted), or tested and discharged to the storm sewer (if not impacted above DEQ surface water standards) in accordance with applicable municipal and State regulations for erosion control and construction stormwater control. 5) Are monitoring wells currently present on the Brownfields Property?.................☐Yes ☒No If yes, are any monitoring wells routinely monitored through DEQ or other 24 EMP Version 2, January 2021 agencies?..................................................................................................................☐Yes ☐No 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): An unnamed tributary of Little Sugar Creek is present along the northwestern and northeastern Brownfields property boundaries. Redevelopment activities that include disturbance to the unnamed tributary are not anticipated at this time. In December 2000, September 2016, and April 2021, a total of nine (9) surface water samples were collected at the Site from upgradient, mid‐gradient, and downgradient portions of the unnamed tributary of Little Sugar Creek. Locations of historical surface water samples are shown in Figure 2, and locations of recent surface water samples are shown in Figure 3. A tabular An inactive water supply well is located along the southern Site boundary. The water supply well will be abandoned in accordance with all applicable regulations prior to redevelopment. The PD is not aware of existing active monitoring wells located on the Brownfields property. DEQ will be notified if newly identified monitoring wells are found on the Brownfields property 25 EMP Version 2, January 2021 summary of recent surface water sample laboratory analytical results is included as Table 3. Historical surface water analytical data is provided as Appendix C. Compound concentrations exceeding DEQ NCAC 15A 2B Surface Water Standards (2B Standards) during the most recent April 2021 sampling event are shown in Figure 4. A brief summary of the surface water assessment results is provided below. Volatile Organic Compounds Surface water sample results indicate that PCE was detected in surface water in upgradient, mid‐ gradient, and downgradient portions of the unnamed tributary at concentrations ranging from 14.6 µg/L in April 2021 to 110 D µg/L in December 2000, which exceed the 2B Standard of 0.7 µg/L. The “D” flag indicates the sample was diluted by the laboratory for analysis. The chlorinated compound TCE was also detected in upgradient and mid‐gradient samples at concentrations ranging from 4.3 µg/L in April 2021 to 23 D µg/L in December 2000, which exceeds the 2B Standard of 2.5 µg/L. The VOCs bromodichloromethane, cis‐1,2‐dichloroethene, 1,2‐dichlorobenzene, and toluene, were also detected in groundwater samples collected at the Site at concentrations above the laboratory method detection limits, but well below the 2B Standards. No other organic compounds were detected in Site surface water at concentrations above the laboratory method detection limits. Semi‐Volatile Organic Compounds No SVOCs were detected at concentrations above the laboratory method detection limits in surface water samples collected at the Brownfields property. Metals Surface water sample results indicated that copper (up to 93.2 µg/L) and nickel (up to 83.8 µg/L) were detected in surface water samples at the Site at concentrations above the site‐specific chronic 2B Standards of 11.14 µg/L and 64.53 µg/L during the December 2000 sampling event. The chronic standard was derived using the DEQ Hardness‐Dependent Metal Calculator dated June 10, 2019 using the average in‐stream hardness value of 129 milligrams per liter as CaCO3. No other metals were detected at concentrations above the 2B Standards in surface water samples collected at the Site and no metals were detected at concentrations above the 2B Standards during the April 2021 assessment activities. If surface water run‐off gathers in an open excavation within an area determined to be impacted during construction activities, appropriate worker safety measures will be undertaken. The accumulated water will be allowed to evaporate/infiltrate to the extent time for dissipation does not disrupt the construction schedule. Should the time needed for natural dissipation of accumulated water be deemed inadequate, the water will be tested and disposed off‐Site (if impacted), or tested and discharged to the storm sewer (if not impacted above DEQ surface water standards) in accordance with applicable municipal and State regulations for erosion control and construction stormwater control. 26 EMP Version 2, January 2021 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): Redevelopment plans that will include disturbance to the unnamed tributary of Little Sugar Creek are not planned at this time. In December 2000 and April 2021, a total of eight (8) sediment samples were collected at the Site from upgradient, mid‐gradient, and downgradient portions of the unnamed tributary of Little Sugar Creek. Locations of historical sediment samples are shown in Figure 2, and locations of recent sediment samples are shown in Figure 3. A tabular summary of recent sediment sample laboratory analytical results is included as Table 4. Historical sediment analytical data is provided as Appendix C. Compound concentrations exceeding DEQ IHSB PSRGs (background concentrations in the case of metals) during the most recent April 2021 sampling event are shown in Figure 4. A brief summary of the sediment assessment results is provided below. Volatile Organic Compounds Sediment sample results indicate that low levels of the VOCs acetone, benzene, cis‐1,2‐ dichloroethene, 1,2‐dichlorobenzene, p‐isopropyltoluene, naphthalene, PCE, toluene, 1,2,4‐ trimethylbenzene, and 1,3,5‐trimethylbenzene were detected in sediment samples collected at the Site at concentrations above the laboratory method detection limits, but well below the DEQ IHSB PSRGs. No other VOCs were detected in Site sediment at concentrations above the laboratory method detection limits. Semi‐Volatile Organic Compounds Sediment sample analytical results indicate that low levels of benzo(a)pyrene (up to 0.42 JD mg/kg) were detected in on‐Site portions of the unnamed tributary at concentrations slightly above the DEQ IHSB Residential PSRG of 0.11 mg/kg. No other organic compounds were detected in Site sediment at concentrations above the DEQ IHSB PSRGs. Metals Sediment sample results indicated that hexavalent chromium (up to 7.1 N mg/kg) was detected in sediment samples collected at the Site at concentrations above background concentrations and the DEQ IHSB Residential and Industrial/Commercial PSRGs of 0.31 mg/kg and 6.5 mg/kg, 27 EMP Version 2, January 2021 respectively. Sediment sample results also indicate lead (435 mg/kg in the SED‐3 duplicate sample) was detected at a concentration above the DEQ IHSB Residential PSRG of 400 mg/kg. No other metals were detected at concentrations above the DEQ IHSB PSRGs or background concentrations in sediment samples collection at the Site. PART 5.

The two (2) sub‐slab vapor samples collected in 2009 were collected under the purview of the DSCA Program to evaluate the potential for vapor intrusion into the 1101 N. Brevard Street Building. A total of three (3) sub‐slab soil gas samples were collected within the Yandle Witherspoon building in footprint of the proposed multi‐family residential apartment building and office building to evaluate the potential for structural vapor intrusion in April 2021. The April 2021 sub‐slab vapor sample locations are shown in Figure 3 and a tabular summary of the laboratory analytical data is provided in Table 5. The September 2009 sub‐slab vapor sample locations are depicted in a map in Appendix C, and a tabular summary of the laboratory analytical data is provided in Appendix C. As shown in Table 5 and Appendix C, no VOCs were detected at concentrations above the DEQ DWM Residential Vapor Intrusion Soil Gas Screening Levels (SGSLs). Hypothetical worst‐case residential use scenario risk calculator results for the soil gas to indoor air vapor intrusion pathway did not exceed the target threshold values for cumulative carcinogenic or noncarcinogenic risks. Although results of residential risk calculations do not exceed the target threshold values, the PD intends to proactively install a DEQ Brownfields Program approved vapor intrusion mitigation system designed by a North Carolina licensed Professional Engineer during construction of the proposed apartment and office buildings. 29 EMP Version 2, January 2021 4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment activities? ☐ Yes ☐ No ☒ Unknown ☐ If no, include rationale here: In the unlikely event impacted vapors are encountered during redevelopment activities, they will be managed in accordance with the procedure outlined below. 5) In the event that contaminated soil vapor is encountered during redevelopment activities, list activities for management of such contact If impacted soil vapors are encountered during future redevelopment activities, worker breathing zone will be monitored using a calibrated photoionization detector by an environmental engineer.

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: No indoor air samples have been collected within the existing warehouse building located at 1001 N. Brevard Street. In 2009 and 2010, H&H collected a total of ten (10) indoor air samples within the commercial building located at 1101 N. Brevard Street on behalf of the DEQ DSCA program. Results of the indoor air sampling activities completed after building renovations were complete did not identify VOC compounds at concentrations that exceeded the acceptable risk levels for non‐ residential workers. The analytical data and a map depicting the locations of the indoor air samples within the commercial building are provided in Appendix C. It is of note that the existing Site buildings will be razed during redevelopment and the PD plans to install a passive vapor intrusion mitigation system during development of the apartment and office buildings. 4) In the event that contaminated indoor air is encountered during redevelopment activities, list activities for management of such contact: In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors) 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 photoionization detector when workers are 30 EMP Version 2, January 2021 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: If yes, ☐ VIMS Plan Attached or ☒ VIMS Plan to be submitted separately If submitted separately provide date: Although results of residential risk calculations do not exceed the target threshold values for cumulative risks, the PD intends to proactively install a DEQ Brownfields Program approved vapor intrusion mitigation system designed by a North Carolina licensed Professional Engineer during construction of the proposed apartment building. The vapor intrusion mitigation plan will be provided under separate cover. 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: 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: present in the Site buildings to identify potential indoor air issues. If results indicate further action is warranted, appropriate engineering controls (such as the use of industrial fans) will be implemented. 31 EMP Version 2, January 2021 ☒ 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 Method 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 sub‐surface environmental conditions (i.e., tanks, drums, or waste materials) that if encountered, will require proper 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 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 environmental actions noted 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 discovery of the UST. If a UST is encountered, the UST will be removed, if possible and the UST will be transported off‐Site for disposal at a suitable facility. If the UST contains residual fluids, the fluids will be sampled for VOCs, SVOCs, and RCRA metals, and transported off‐Site for disposal at a suitable facility based on the laboratory analytical results prior to removing the UST from the ground. If a UST is encountered that cannot be removed or does not require removal for geotechnical or construction purposes, it may be abandoned in‐place with prior DEQ approval and construction will proceed. Where appropriate, the bottom may be penetrated before abandonment to prevent fluid accumulation. Impacted soil in the vicinity of the UST will be managed in accordance with the Managing On‐Site 32 EMP Version 2, January 2021 Soil section outlined above in the EMP. DEQ UST Program protocol (or other protocol approved in advance by the DEQ Brownfields Program) will be followed for UST abandonment procedures. 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 back filling to prevent fluid accumulation. If the pit has waste in it, the waste will be set aside in a secure area and will be sampled for waste disposal 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: If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to stop work in that location and notify the environmental consultant. The environmental consultant will review the materials and collect samples, if warranted. In this event, 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. Areas of suspected contaminated soil that remain at the Site after excavation is complete above the DEQ IHSB Residential PSRGs will be managed pursuant to this plan. Re‐Use of Impacted Soils On‐Site: Please refer to description outlined in the Managing On‐Site Soil section (Part 1A) 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.

This request was submitted on your behalf by Mr. Chris Corbitt, PG of Terracon Consultants, Inc. on October 16, 2018 via the Composite Soil Sample Analytical Results Summary and Soil Export Request letter. Transfer to another Brownfields property was subsequently approved; however, per recent phone conversations with Mr. Corbitt the transfer of soils associated with CS-05 samples to another brownfields property was no longer an option. DEQ Brownfields and Solid Waste Section reviewed the provided stockpile sampling results as well as previously collected soil samples for arsenic from the Reeves Land Clearing and Inert Debris Landfill. Based upon our review, the stockpiled soils may be managed as follows: • Soils associated with samples CS-05/CS-05A may be managed at the Reeves LCID Landfill, or another LCID Landfill with background arsenic concentrations similar to those identified at the Brownfields Property, a Construction & Demolition (C&D) Landfill, Municipal Solid Waste (MSW) Landfill, or at another Brownfields Property with prior DEQ Brownfields approval. • Soils associated with the samples CS-06/CS-06A may be managed at a MSW Landfill, or at another Brownfields Property with prior DEQ Brownfields approval. Per the Highland Park Mill EMP, the soils will be field screened during excavation prior to export from the property. If unanticipated impacts are identified during excavation, please refer to the EMP for further actions and cease transfer until appropriate characterization can be completed. Mr. Jay Levell October 31, 2018 Page 2 In accordance with the site’s approved EMP, an annual Redevelopment Summary Report will be submitted to DEQ Brownfields. Details related to the disposition of this soil including but not limited to, total volume, general description of field screening efforts, etc. should be included with the Redevelopment Summary Report. Please be advised that this approval does not waive any applicable requirement to obtain any necessary permits, licenses or certifications which may be required from other state or local entities.
