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 So that the EMP provides value in protecting brownfields eligibility and public health, the preparer shall ensure that the following steps have been completed prior to submitting the EMP for review. Any EMP prepared without completing these steps is premature. ☒ Site sampling and assessment that meets Brownfields’ objectives is complete and has been reviewed and approved by the Brownfields Project Manager. ☒ Specific redevelopment plans, even if conceptual, have been developed for the project, submitted and reviewed by the Brownfields Project Manager. 2 EMP Version 2, June 2018 Please submit, along with the completed EMP form, the following attachments, as relevant and applicable to the proposed redevelopment: ☒ A set of redevelopment plans, including architectural/engineering plans, if available; if not conceptual plans may suffice if updated when detailed plans are drafted. ☐ A figure overlaying redevelopment plans on a map of the extent of contamination for each media. ☒ Site grading plans that include a cut and fill analysis. ☐ A figure showing the proposed location and depth of impacted soil that would remain on site after construction grading. ☐ Any necessary permits for redevelopment (i.e. demolition, etc.). ☐ A detailed construction schedule that includes timing and phases of construction. ☒ Tabulated data summaries for each impacted media (i.e. soil, groundwater, soil gas, etc.) applicable to the proposed redevelopment. ☒ Figures with the sampling locations and contamination extents for each impacted media applicable to the proposed redevelopment. ☐ A full final grade sampling and analysis plan, if the redevelopment plan is final. ☐ If known, information about each proposed potential borrow soil source, such as aerial photos, historic site maps, historic Sanborn maps, a site history, necessary for brownfields approval. ☐ Information and, analytical data if required, for quarries, or other borrow sources, detailing the type of material proposed for importation to the Brownfields Property. ☐ A work plan for the sampling and analysis of soil to be brought onto the Brownfields Property. Refer to Issue Resolution 15 in Brownfields Program Guidelines. ☐ A map of the Brownfields Property showing the location of soils proposed for export and sampling data from those areas. ☐ If a Vapor Mitigation System is required by the Brownfields Program, the Vapor Intrusion Mitigation System (VIMS) plan will be signed and sealed by a NC Professional Engineer. The VIMS Plan may also be submitted under separate cover. 3 EMP Version 2, June 2018 COMMUNICATIONS Date: 3/4/2021 Revision Date (if applicable): Brownfields Assigned Project Name: Southern Steel Brownfields Project Number: 23052-19-060 Brownfields Property Address: 3015 Wilkinson Boulevard, Charlotte, Mecklenburg County, North Carolina (Figure 1) Brownfields Property Area (acres): 5.19 Is Brownfields Property Subject to RCRA Permit?.......................☐ Yes ☒ No If yes enter Permit No.: Is Brownfields Property Subject to a Solid Waste Permit….……..☐ Yes ☒ No If yes, enter Permit No.: A copy of this EMP shall be distributed to all the parties below as well as any contractors or site workers that may be exposed to site vapors, soil, groundwater, and/or surface water.

Soil sample locations are shown on Figure 2. A brief summary of the results is provided below. Chloroform (0.81 mg/kg) was detected at an estimated “j-flag” concentration in sample SS-1 (2-4 ft) above the residential PSRG of 0.34 mg/kg but below the industrial/commercial PSRG of 1.5 mg/kg. Sample SS-1 was collected from the western portion of the Site in the southeastern portion of proposed Building 1. Chloroform is a common laboratory contaminant; therefore, the detection may not be representative of site soil conditions. Several polycyclic aromatic hydrocarbons (PAHs) were detected at concentrations above the residential PSRGs in soil sample SS-1A (2-3 ft), which was collected adjacent to sample SS-1 in the southeastern portion of proposed Building 1. 7 EMP Version 2, June 2018 Hexavalent chromium was detected above the residential PSRG at concentrations ranging from 2.48 mg/kg to 4.01 mg/kg in samples SB-10 (1-3 ft), SB-11 (1-3 ft), SB-13 (1-3 ft), and SB-14 (1-3 ft), which were collected near former steel fabrication areas in the western, central, and eastern portions of the site. Arsenic (up to 3.51 mg/kg) was also detected above residential and/or industrial/commercial PSRGs is samples collected from the western, central, and eastern portions of the site. Lead was detected in multiple samples collected in the central and western portions of the site at concentrations above the residential and/or industrial/commercial PSRGs. Lead detections above the PSRGs ranged from 534 mg/kg in sample SB-2 (1-3 ft) to 1,240 mg/kg in sample SB-3 (1-3 ft). Subsequent waste characterization sampling was performed and indicated characteristically hazardous levels of lead may be present in an approximate 0.3-acre area to a depth of at least 4 ft within and adjacent to the west, north, and east of proposed Building 1 in the western portion of the site. Specifically, lead was detected in leachate from composite samples B1-A( (13.5 mg/L), B1-B (26 mg/L), Comp-1 (11.4 mg/L), and Comp-3 (5.8 mg/L) at concentrations above the EPA Maximum Concentration for Toxicity Characteristic Leaching Procedure (TCLP) of 5.0 mg/L. The results of soil characterization sampling are summarized in Table 2. The approximate area of potential characteristically hazardous lead in soil (referred to as “Area 1”) is depicted on Figure 3. Additional metals, including barium, beryllium, cadmium, chromium, cobalt, manganese, mercury, nickel, and selenium, were detected at concentrations below PSRGs. 2) Depth of known or suspected contaminants (feet): 1.0-4.0 feet. 3) Area of soil disturbed by redevelopment (square feet): The area of potential soil disturbance is estimated to be approximately 3.22 acres (approximately144,586 square feet) of the 5.19-acre site. The area of potential disturbance will consist of the existing gravel/grass-covered area located north of the Norfolk Southern railroad right-of-way and south of the access road located along the northern site boundary. 4) Depths of soil to be excavated (feet): 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Based on conservative estimates of up to 3,000 cubic yards of excavation during grading, up to Shallow soil disturbance (i.e., up to 1 ft) is currently planned as part of initial grading activities to remove organic-rich topsoil beneath proposed building foundations. Cut depths in the eastern portion of the Site range from approximately 1 to 4 ft bgs. Excavation for the installation of new utilities may include trenching to depths of up to 8 ft bgs. Beneath proposed building foundations, aggregate piers will be installed to partially weathered rock at depths of approximately 20 ft bgs. 8 EMP Version 2, June 2018 Part 1.A. MANAGING ONSITE SOIL 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: See answer to Part 1, Section 6 above. 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). ☐ If yes, do the soils exceed the “Contained-Out” levels in Attachment 1 of the North Carolina Contained-In Policy?................................................. ☐ Yes ☒ No b) NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS THE CONTAINED-OUT LEVELS IN ATTACHMENT 1 TO THE NORTH CAROLINA CONTAINED-IN POLICYTHE SOIL MAY NOT BE RE-USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITHDEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS. c) Does the soil contain a CHARACTERISTIC WASTE?.................................... ☒ Yes ☐ No ☐ If yes, mark reason(s) why below (and include pertinent analytical results). ☐ Ignitability Excavation of up to approximately 2,000-2,500 cubic yards of impacted soil is anticipated. The impacted soil is proposed to be used as fill material in areas of proposed parking lots and driveways. Excavated soils that cannot be re-used as fill material on-site will be transported to a municipal solid waste landfill under standard manifest protocol or stockpiled for composite sampling as outlined in Part 1.C. Soil removed from “Area 1” will be stockpiled and treated by blending/lead-stabilization methods, tested through composite sampling to confirm that the soil is characteristically non-hazardous, and placed in a designated area on-site. The final on-site location(s) of soil from “Area 1” will be depicted on the Brownfields Plat. Refer to Part 1.A., Item 4 for further discussion of soil management procedures for “Area 1”. 500 cubic yards of soil removal during installation of aggregate piers, up to 500 cubic yards of soil excavation during construction of spread footings, and additional soil during utility installation, approximately 4,000-4,500 cubic yards of soil may be disturbed. 9 EMP Version 2, June 2018 ☐ Corrosivity ☐ Reactivity ☐ Toxicity ☒ TCLP results Results of soil characterization sampling indicate that lead is present at characteristically hazardous levels in an approximate 0.3-acre area ☐ Rule of 20 results (20 times total analytical results for an individual hazardous constituent on TCLP list cannot, by test method, exceed regulatory TCLP standard) ☐ If no, explain rationale: d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE SOIL MAYNOT BE RE-USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS. 2) Screening criteria by which soil disposition decisions will be made (e.g., left in place, capped in place with low permeability barrier, removed to onsite location and capped, removed offsite): ☐ Preliminary Health-Based Residential SRGs ☒ Preliminary Health-Based Industrial/Commercial SRGs ☒ Division of Waste Management Risk Calculator (For Brownfields Properties Only) ☐ Site-specific risk-based cleanup level. Please provide details of methods used for determination/explanation. Additional comments: 3) If known impacted soil is proposed to be reused within the Brownfields Property Boundary, please check the measures that will be utilized to ensure safe placement and documentation of same. Please attach a proposed location diagram/site map. ☒ Provide documentation of analytical report(s) to Brownfields Project Manager ☒ Provide documentation of final location, thickness and depth of relocated soil on site map to Brownfields Project Manager once known ☐ Geotextile to mark depth of fill material. Provide description of material: ☒ Manage soil under impervious cap ☒ or clean fill ☒ as “Area 1” and is depicted on Figure 3. to a depth of at least 4 ft within and adjacent to the west, north, and east of proposed Building 1 in the western portion of the site. This area is identified 10 EMP Version 2, June 2018 ☒ Describe cap or fill: ☒ Confer with NC BF Project Manager if Brownfield Plat must be revised (or re-recorded if actions are Post-Recordation). ☒ GPS the location and provide site map with final location. ☐ Other. 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: ☐ No, explain rationale: Field Screening of site soil ☒ Yes, describe the field screening method, frequency of field screening, person conducting field screening: ☐ No, explain rationale: Soil Sample Collection ☒ Yes, describe the sampling method (e.g., in-situ grab, composite, stockpile, etc.): During soil disturbance at the site, the workers or contractors will observe soils for evidence of potential impacts. Evidence of potentially 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 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 DEQ Brownfields project manager will be contacted within 48 hours to advise of the condition. 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. If suspect contaminated soil is encountered during site 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. Should impacted soil be encountered during redevelopment, the potentially impacted soil will be placed beneath impervious surfaces (asphalt pavement, sidewalks, buildings, etc.) or a minimum of 2 ft of demonstrably clean fill. 11 EMP Version 2, June 2018 ☒ No, explain rationale: Collection of additional soil samples other than composite sampling noted above is not anticipated based on the results of previous site assessment activities. However, if significant soil impact is encountered in areas not previously assessed, excavation will proceed only as far as needed to allow grading or other construction-related activity to continue only as far as needed to allow alternate corrective measures as described below. Suspect significantly impacted soil excavated during redevelopment activities may be stockpiled and covered in a secure area to allow construction to progress. 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 sample of the soil will be collected for analysis of total VOCs, SVOCs, RCRA metals, and hexavalent chromium as outlined in Part 1.C. If the results of analysis of the sample 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 handled 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 industrial/commercial PSRGs or are consistent with site-specific background levels, 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 Municipal Solid Waste Landfill [MSWLF]) 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 industrial/commercial PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with site-specific background levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil may be used on- site as fill without conditions. The PD will perform composite sampling of stockpiled soil generated during grading activities, aggregate pier installation, and foundation construction in “Area 1”. Soil will be stockpiled in accordance with Figure 1 – NCBP Diagram for Temporary Containment of Impacted or Potentially Impacted Soil. Soil excavated from “Area 1” will be segregated from the remainder of material that will be stockpiled prior to export from the site. Refer to Part 1.C. for a description of sampling procedures for exported soil. Sampling procedures for soil excavated from the “Area 1” will outlined in a Hazardous Soil Removal and Treatment Work Plan, which will be submitted for DEQ Brownfields Program approval prior to disturbance of “Area 1”. 12 EMP Version 2, June 2018 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 Method 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): ☐ PCBs: Specify Analytical Method Number(s): ☒ 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. Stockpile methodology should provide erosion control, prohibiting contact between surface water/precipitation and contaminated soil, and preventing contaminated runoff. Explain any variances or provide additional details as needed: ☒ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or permanent hardscape). Select chemical analyses for final grade samples with check boxes below (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 iii. If detectable levels of compounds are found which exceed the industrial/commercial 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’s written approval, may be used on-site as fill below an impervious surface, at least 2 ft of compacted clean soil, or 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 with a geotechnical fabric. iv. Impacted soil may be transported to a MSWLF provided that the soil is accepted at the disposal facility. If soil is transported to a permitted facility, the permitted facility’s written approval to dispose of soil from the site will be included with the final EMP 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 MSWLF that can accept or treat hazardous waste. 13 EMP Version 2, June 2018 Part 1.B. IMPORTED FILL SOIL ☒ 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): ☐ PCBs: Specify Analytical Method Number(s): ☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Hexavalent chromium by EPA Method 7199 Please provide a scope of work for final grade sampling, including a diagram of soil sampling locations, number of samples to be collected, and brief sampling methodology. 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, a work plan for final grade sampling may be submitted under separate cover. ☐ If final grade sampling was NOT selected please explain rationale: 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 Following completion of soil disturbance for any future site development (i.e. after grading and utility construction), an environmental professional will be contracted to assess the site for areas that are not covered with demonstrably clean fill soil, building foundations, sidewalks, asphalt or concrete parking areas, driveways, or other impervious surfaces. If such areas exist, a Work Plan will be prepared for final grade sampling for DEQ review and approval. If no such areas exist, documentation will be provided to the DEQ Brownfields project manager. 14 EMP Version 2, June 2018 2) If yes, what is the estimated volume of fill soil to be imported? 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.) 0 to 5 feet 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: 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. 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): 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): ☐ PCBs: Specify Analytical Method Number(s): ☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Hexavalent chromium by EPA Method 7199 Please see No. 7 below for details outlining the proposed plan to demonstrate import soil meets acceptable standards applicable to the site. The PD also plans to import limited amounts of virgin 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. DEQ Brownfields will be notified of the volume of landscaping material needed and the proposed source of the material prior to placement in proposed landscaping areas. The source(s) of fill material have not been confirmed. However, the PD intends to use existing soil data for the site and other local Brownfields properties to identify a DEQ-approved Brownfields export site. Alternatively, the PD will import fill material from the Vulcan Materials Company quarry located near Pineville, NC or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC. Up to approximately 9,000 cubic yards of structural fill is anticipated to be imported to the site. In addition, limited amounts of virgin topsoil may be imported from a commercial landscape material vendor for use in proposed landscaped areas. 15 EMP Version 2, June 2018 Part 1.C. EXPORTED SOIL 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. 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. Up to approximately 2,000 cubic yards of export soil is anticipated to be generated during grading, foundation construction, trenching, and aggregate pier installation. As noted in Part 1.A. Section 4 (Soil Sample Collection), composite sampling of soil stockpiles will be performed. If stockpiled soil which originated outside of “Area 1” cannot be reused on-site, the soil will be characterized prior to export from the site. H&H will sample the soil stockpile(s) 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 known permitted quarry, soil samples will be collected for laboratory analyses indicated above at a general rate of one per 1,000 cubic yards. If the borrow source property has been previously developed, soil samples will be collected for laboratory analyses indicated above at a general rate of approximately one per 500 cubic yards. Composite soil samples for SVOC, RCRA metals, and hexavalent chromium analysis will consist of 3-5 sample aliquots, and grab soil samples will be collected for VOC analysis. Fill soil will be considered suitable for use at the site if it does not contain compound concentrations above DEQ IHSB industrial/commercial PSRGs and metals concentrations are generally consistent with the subject property. 16 EMP Version 2, June 2018 at a rate of approximately one sample per 500 cubic yards. Stockpile samples will be collected for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Method 6020/7471, and hexavalent chromium by EPA Method 7199. Sample volume for SVOCs and metals analysis will be collected as composite samples using a decontaminated stainless-steel hand auger. The composite samples will consist of five sample aliquots that are combined to form one sample for laboratory analysis. Each aliquot will be field screened for the presence of VOCs using a calibrated PID. VOC samples will be collected as grab samples using a decontaminated stainless-steel hand auger from the general area of the aliquot which exhibits the highest indication of impact during field screening. The soil collected for VOC analysis shall be collected from non-homogenized, non-screened soils to reduce volatilization of potential contaminants. Following completion of the soil assessment 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 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 MSWLF (e.g., another Brownfields property or a non-Brownfields property), DEQ Brownfields and Solid Waste Section 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. 17 EMP Version 2, June 2018 Part 1.D. MANAGEMENT OF UTILITY TRENCHES 3) Additional Details: (if transfer of soil to another property is requested above, please provide details related to the proposed plans). ☐ 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: ☒ Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in the event that evidence of contaminated soil and/or vapors are encountered in utility trenches during redevelopment activities (e.g., unusual odors are identified or workers report lightheadedness or other unusual physical reaction), 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. Due to the lack of obvious field evidence of lead contamination and the extent of lead-impacted soil identified during previous assessment of the site, field screening for the presence of lead is not warranted. However, contractors will be observed by an environmental professional when trenching within the “Area 1” to ensure that appropriate worker safety measures are implemented. Evidence of potential significant impacted soil from contaminants such as VOCs and SVOCs 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 professional to observe the suspect condition and screen the soil using a photo-ionization detector (PID) or other similar vapor field screening instrument. If the project environmental professional confirms that the material may be impacted, then the procedures outlined Managing On-Site Soil above (Part 1.A.) will be implemented. The environmental professional will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ Solid Waste approval prior to exporting soil to a non-MSWLF. If no, include rationale here: VOCs are not considered site-specific contaminants of concern. Therefore, evaluation of soil vapor is not warranted during site redevelopment. 18 EMP Version 2, June 2018 PART 2. GROUNDWATER – Please fill out the information below. 1) What is the depth to groundwater at the Brownfields Property? 2) Is groundwater known to be contaminated by ☒onsite ☐offsite ☐both or ☐unknown sources? Describe source(s): 3) What is the direction of groundwater flow at the Brownfields Property? Groundwater flow at the site is expected to mimic topography and flow toward the southwest. 4) Will groundwater likely be encountered during planned redevelopment activities? ☐ Yes ☒No If yes, describe these activities: 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). Although not anticipated at this time, 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 Groundwater is not anticipated to be encountered during the proposed redevelopment of the site. See below for groundwater management procedures in the unlikely event that groundwater is encountered. A tabular summary of historical groundwater analytical data in comparison to the North Carolina Administrative Code (NCAC) 2L Groundwater Standards (2L Standards) is included as Table 3, and groundwater sample locations are shown on Figure 2. A summary is provided below. Several metals, including arsenic, barium, beryllium, cadmium, chromium, copper, cobalt, lead, manganese, mercury, nickel, selenium and/or silver, were detected in groundwater samples collected at the site. In 2010, arsenic, barium, chromium, lead, and/or mercury were detected at concentrations above the 2L Standards in samples BH-8 and BH-12, which were collected near a former septic tank and UST. Based on groundwater data for sample TMW-1, which was collected in 2019 near former samples BH-8 and BH-12, the 2010 metals detections in groundwater may be associated with high turbidity. Cobalt and manganese were detected at concentrations above the regional background concentration and 2L Standard or Interim Maximum Allowable Concentration (IMAC) in samples TMW-1, TMW-2, and TMW-3, which were collected in the western portion of the site in March 2019. Chromium was detected slightly above the 2L Standard in background sample TMW-4, which was collected in the northeastern (upgradient) portion of the site. Depth to groundwater was measured at approximately 5.5 to 10 ft bgs in temporary monitoring wells installed at the site. In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours to advise that person of the condition. 19 EMP Version 2, June 2018 PART 3.

CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials not be demolished as part of redevelopment activities, will workers encounter contaminated indoor air during planned redevelopment activities? ☐ Yes ☒ No ☐ Unknown 4) In the event that contaminated indoor air is encountered during redevelopment activities, list activities for management of such contact: Is a vapor intrusion mitigation system (VIMS) proposed for this Brownfields Property? ☐ Yes ☒ No ☐ Unknown If yes, ☐ VIMS Plan Attached or ☐ VIMS Plan to be submitted separately If submitted separately provide date: 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: 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: Based on the results of prior soil and groundwater sampling at the site, VOCs are not site-specific contaminants of concern. Therefore, there does not appear to be a vapor intrusion risk for non- residential workers in the proposed on-site structures, and a vapor mitigation plan is not warranted for the proposed redevelopment of the site. 23 EMP Version 2, June 2018 ☒ 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 Method 6020 and EPA Method 7471 ☐ Pesticides: Specify Analytical Method Number(s): ☐ PCBs: Specify Analytical Method Number(s): ☒ 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 and RCRA metals by TCLP Please provide details on the proposed methods of managing the following commonly encountered issues during redevelopment of Brownfields Properties. Underground Storage Tanks: based on the laboratory analytical results. Impacted soil will be managed in accordance with the Managing On-Site Soil section outlined above in the EMP. 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. Given the potential residential use of the site in the future, the fluids (if present) and the UST will be removed and transported off-site for disposal at a suitable facility 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. 24 EMP Version 2, June 2018 POST-REDEVELOPMENT REPORTING Sub-Grade Feature/Pit: Buried Waste Material: Re-Use of Impacted Soils On-Site: 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: ☒ 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 1/31/2022 Please refer to description outlined in the Managing On-Site Soil section (Part 1.A.) of the EMP above. 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 the laboratory parameters listed above. Areas of suspected contaminated soil that remain at the site after excavation is complete above the DEQ residential PSRGs will be managed pursuant to this plan. If a sub-grade feature or pit is encountered, it will be removed and the excavation will be filled with soil or suitable fill and construction will proceed. If the pit has waste in it, the waste may 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 observed waste characteristics indicate the concrete or other construction material (e.g., brick) from the pit may potentially be contaminated to a significant degree, the concrete or other construction material (e.g., brick) will be sampled and analyzed by methods specified by the disposal facility. 25 EMP Version 2, June 2018 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 ultimate disposition of any soil, groundwater or other materials suspected or confirmed to be contaminated with regulated substances;
