The EMP is a standard requirement of a Brownfields Agreement (BFA). Its purpose is to clarify actions to be taken during 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 EMP to be valid for use, it must be completed, reviewed by the Section, 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 recorded 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. Risk characterization of a Brownfields Property to DEQ’s written satisfaction is required prior to EMP approval. Voluntary Metrics Tab The NC Brownfields Redevelopment Section updates estimated capital investment (from the Brownfields Property Application) and estimated jobs created (from the Brownfields Agreement) whenever possible.

Describe the field screening method, frequency of field screening, person conducting field screening: As part of the review of the EMP approved by NCBRS, the General Contractor (GC) will be made aware of the typical visual and/or olfactory evidence that is associated with potentially contaminated soils (e.g., staining, odors, solid waste, etc.), including screening of soils with a photoionization detector (PID). If an unknown area of concern is encountered, redevelopment activities in the area will be suspended. The construction company will immediately notify S&ME and the PD. A qualified environmental professional from S&ME will assess the area, evaluate the waste materials and/or impacted media in the area, if present, and determine the proper means for managing these materials. Within 48 hours, S&ME will inform NCBRS of the findings and subsequent actions to be taken for managing these materials. Click or tap here to enter text. 13 EMP Version 3, March 2023 Soil sample collection ☒ Yes ☐ Not anticipated - In order to avoid delays in construction, a plan shall be in place for sampling of suspect soils should they be encountered during redevelopment. If soil sample collection is not anticipated but the need to do so is identified during redevelopment, notify the Brownfields project manager of the anticipated sample and report dates for scheduling purposes. Describe the sampling method (e.g., in-situ grab, composite, stockpile, etc.) and confirm that all procedures outlined in applicable DEQ guidance for assessment shall be followed Typically, at least one representative sample (per 500 yd3 for residential and 1,000 yd3 for commercial) consisting of a 3 to 5-point composite sample with grab sample for VOCs based on the highest PID reading is required to determine soil management options: In the event of the discovery of unknown or impacted media during redevelopment activities, the site work in this location will halt and the contractor will notify S&ME and the PD. The materials will be sampled and characterized based on the recommended sampling frequency for a residential development of one 3-point to 5-point composite, representative sample with a grab sample for VOCs collected based on the highest reading from a PID. Based on the contents, the material will be removed and transported off-site for proper disposal by a qualified environmental waste management company. Should grossly impacted soil removal be required, confirmatory samples collected from the newly discovered contaminant source area(s) will be submitted to a North Carolina certified laboratory for analysis. Analytical methods to be employed for these samples will include the following: VOCs by Method 8260; SVOCs by Method 8270; RCRA Metals by Methods 6010/7471, and hexavalent chromium by Method 7199. Additional analyses may be required based on field observations and requirements from NCBRS. An environmental waste management company will be contracted to clean up any hazardous substances that may have been released/discovered. Redevelopment activities will not resume until after released hazardous substances have been removed, and any explosive or dangerous atmospheric conditions have been mitigated. Should impacted soils be reused on the site, the NCBRS Project Manager will be notified within 48 hours and consulted as to potential for further sampling, reporting, and mitigation. Soil will need to be tested in accordance with the approved EMP and NCBRS approval must be obtained prior to re-use. 14 EMP Version 3, March 2023 Check applicable chemical analytes for soil samples: ☒ Minimum Sample Requirements: Volatile organic compounds (VOCs) by EPA Method 8260; Semi-volatile organic compounds (SVOCs) by EPA Method 8270; and Metals RCRA List + Hexavalent Chromium by EPA Method 6020/7199 ☐ 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) (e.g. Herbicides): Click or tap here to enter text. ☒ Check to confirm that by the owner’s signature and the North Carolina Professional Engineer/Geologist sealing this EMP the consultant understands that no work plan for suspect soil sample collection will be submitted beyond this EMP, and that it is the responsibility of the sealing professional and property owner to ensure that all applicable guidelines and methodologies are followed and reported to DEQ for determination and approval of soil placement prior to final relocation.

Figure 06 in Appendix II is an engineering plan from PGE showing the existing elevations and proposed elevations to further illustrate the fill areas. Figure 10 in Appendix II depicts the "cut" areas in red and the "fill" material areas in blue. The limited “cut” of surficial soils, show in the red, will remain on-site. The blue “fill” areas will be filled by the GC with fill materials imported from NCBRS-approved sources. Approximately over 90% of the site will be filled to raise the existing site grades to the proposed higher elevations. PRIOR TO SOIL PLACEMENT AT THE BROWNFIELDS PROPERTY, a Soil Import Request must be submitted for DEQ Brownfields review and approval. The request shall consist of a data package that details: - Fill source location/history (Phase I if available, current aerials, etc.) - Analytical data that has been sampled in accordance with the below frequency and following procedures outlined in the most recent Brownfields Redevelopment Section Environmental Site Assessment Work Plan Minimum Requirements Checklist (Checklist) and in accordance with DEQ IHSB Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines) - A table comparing the import soil to existing site concentrations - A PE/PG recommendation of import - All relevant attachments listed in the Checklist 17 EMP Version 3, March 2023 Soil Import Sampling Requirements: Source Sample Frequency Sample Analysis Virgin Material from DEQ Brownfields Pre- approved Quarry None (Contact Brownfields project manager for list of pre- approved Quarries DEQ Permitted Quarry (Not Brownfields Pre- approved) At least one representative sample from area of planned import VOCs, SVOCs, RCRA Metals, any site specific COCs (e.g. pesticides, PCBs, etc.) Other NC DEQ Brownfields Property At least one representative sample per 1,000 yd3 consisting of a 3-point composite sample with grab sample for VOCs based on the highest PID reading VOCs, SVOCs, RCRA Metals, any site specific COCs (e.g. pesticides, PCBs, etc.) Off-site unpermitted/regulated property Bulk Landscape Material from Commercial Vendor (i.e. topsoil) No Sampling Required If other special considerations apply, discuss: At this time, the PD is considering the following local sources of import materials: • Vulcan Quarry – 4401 Patterson Ave, Winston-Salem, NC • Martin Marietta – Salem Stone Quarry - 4572 High Point Road, Kernersville, NC The PD understands that the above-identified potential fill sources have not achieved pre- approved status from NCBRS and will require soil import sampling and analysis in accordance with the table above and other NCBRS requirements (at a minimum analyzed for VOCs, SVOCs, 8 RCRA Metals and hexavalent chromium). As of the date of this revised EMP, up to 3,500 cubic yards of soils were approved by NCBRS for export from the Carolina Medical Electronics site to the proposed 450 Polo Road development. The approval was granted by NCBRS in correspondence dated August 3, 2023. As previously discussed with NCBRS, the PD is evaluating other potential sources of import fill including other local developments and NCBRS-approved Brownfields sites, and/or the use of a borrow source(s). S&ME and the PD will update and request approval from NCBRS for potential sources of fill materials, including sampling and analysis of potential import soil. The PD assumes that stone, gravel or similar materials (virgin material from NCBRS-approved sources) do not require testing under this EMP or NCBRS approval. The PD acknowledges that recycled materials may require testing. 18 EMP Version 3, March 2023 ☒ Check to confirm that by the owner’s signature and the North Carolina Professional Engineer/Geologist sealing this EMP the consultant understands that no work plan for suspect soil sample collection will be submitted beyond this EMP, and that it is the responsibility of the sealing professional and property owner to ensure that all applicable guidelines are followed and reported in the Soil Import Request for DEQ approval.

(S&ME) has prepared this Final Grade Sampling and Analysis Plan (Plan) on behalf of 450 Polo Road, LLC, the Prospective Developer (PD) for the development. The purpose of this Plan is to obtain North Carolina Department of Environmental Quality (NCDEQ), Brownfield Redevelopment Section (BRS) approval of the proposed soil sampling locations within the anticipated final development areas. The following sections provide the (1) regulatory requirements for the proposed sampling activities based on the BRS’s comments and the Environmental Management Plan (EMP) for the development, (2) proposed soil sampling methodologies and laboratory analyses and (3) estimated sampling and reporting schedule based on the current project construction schedule.  Proposed Development The proposed development is for 17 2-story and 3-story townhomes (“For-Rent-Only” residential units). The development will include a total of approximately 23,000 square feet (SF) of residential townhome/residential unit footprints, residence access sidewalks, landscaped areas surrounding the development and within the parking areas, paved parking areas and a Clubhouse area with a pool. Based on the EMP, approximately 23,400 cubic yards of imported fill will be brought onsite as part of the development based on the cut/fill calculations. Based on the most recent site plan included in the EMP, nearly 167,000 SF will be disturbed during site development and approximately 60,600 SF of the proposed development will be pervious areas (areas not “capped” by buildings, sidewalks, paved parking areas, etc.), as shown on Figure 1, which will be available for final grade soil quality sampling and analysis. Final Grade Sampling and Analysis Plan – 450 Polo Road Brownfields Project No.: 25052-21-034 August 18, 2023 Page 2 S&ME, Inc.  Soil Sampling Locations, Methodology and Laboratory Analysis Based on comments provided by NCBRS during August 2023, Figure 1 shows the sampling locations within the NCBRS-identified areas of the development and Table 1 summarizes the proposed soil sampling and analysis. The approximate square footage for Sampling Areas 1 through 7 are provided in Table 1 and summarized below:  Area 1 - 8,900 SF  Area 2 – 6,350 SF  Area 3 – 9,100 SF  Area 4 – 6,700 SF  Area 5 – 5,700 SF  Area 6 – 14,000 SF  Area 7 – 9,900 SF Soil sampling will be conducted in accordance with the sampling procedures outlined in the NCDEQ Inactive Hazardous Site Branch’s (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites (September 2022). Soil type, relative moisture content, and other lithologic characteristics will be documented in the field. Each soil sample will be composited from four aliquot locations by advancing a decontaminated hand auger to approximately 2-feet below ground surface (bgs) at each location. The soils from each sample location will be divided equally with one-half placed in a sealed plastic bag that is placed on ice within a cooler and the other half placed in a sealed plastic bag that is allowed to volatilize for approximately 5 to 10 minutes. After the volatilization period, the headspace of the second plastic bag (not placed on ice) will be screened for volatile vapors using a photo-ionization detector (PID). A grab sample for VOC analysis will be collected from the corresponding sealed plastic bag that had been stored on ice from the location exhibiting the highest PID reading. For composite sample collection, soils from the sealed plastic gas (placed on ice) from each set of borings will be composited using a decontaminated stainless-steel bowl and spoon via the sample homogenization procedures outlined in the U.S. Environmental Protection Agency’s SESDPROC-300-R3 (June 11, 2020) guidance. Therefore, S&ME proposes the following:  Seven (7) grab or discrete soil samples will be collected from the one to foot bgs interval for analysis of volatile organic compounds (VOCs) by EPA Method 8260. The grab or discrete soil sample will be selected based on field screening results (e.g., results from a PID, visual or olfactory observations).  Seven (7) composite samples (4-point composites) will be collected from each Sampling Area for analysis of semi-volatile organic compounds (SVOCs) by EPA Method 8270, the eight (8) Resource Conservation and Recovery Act (RCRA) metals by EPA Methods 6010/7471 and hexavalent chromium by EPA Method 7199.  Each composite soil sample will be comprised of a minimum of four (4) sub-samples (e.g., 4-point composite) collected from the ground surface to approximately 2 feet bgs.  The locations of the discrete samples sub-samples will be recorded using Global Positioning System (GPS) coordinates using a hand-held device (or equivalent) and identified on a map. Final Grade Sampling and Analysis Plan – 450 Polo Road Brownfields Project No.: 25052-21-034 August 18, 2023 Page 3 S&ME, Inc.  S&ME will collect one duplicate discrete sample and one composite sample for the analysis parameters detailed above per NCDEQ quality assurance/quality control (QA/QC) guidelines.  Sample Handling and Laboratory Quality Control Procedures Soil samples will be placed into laboratory-provided containers and submitted under strict chain-of-custody protocol to a NCDEQ and NELAP-certified analytical laboratory for analysis. Laboratory reporting limits (RLs) and method detection limits (MDLs) used by the designated laboratory will meet the applicable NCDEQ Division of Waste Management (DWM) PSRGs (January 2023), to the extent feasible. Concentrations detected between the RL and MDL will be reported as estimated values and flagged in the laboratory analytical report with a “J” qualified. Level II QA/QC will be reported by the laboratory in the analytical report deliverable.  Reporting After receipt and review of the laboratory analytical results (anticipated in August/September 2024), S&ME will prepare a Final Grade Sampling and Analysis Report (Report) for NCBRS’ review and approval. The Report will include the following:  Summary of the field activities and laboratory analytical results in a tabulated format including a figure showing the approximate sampling locations.  A comparison to the applicable NCDEQ Residential PSRGs.  Analytical results will be evaluated using the most up-to-date version of the NCDEQ Risk Calculator.  Copies of the laboratory analytical reports, field notes and tabulated PID results recorded during the sampling activities.  Closing Please contact the undersigned with any questions or comments regarding this Plan.
