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 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. As a voluntary measure, you may opt to complete the below information for capital investment and jobs created as estimated by your final redevelopment plans for the Brownfields Property: 1. Estimated capital investment in redevelopment project: $40M for low-income, age - restricted multifamily apartment complex.

EMP review without such information would be premature): Provide brief summary of redevelopment plans, including demolition, removal of building slabs/pavement, grading plans and planned construction of new structures: Redevelopment plans for the Hoke Street Property include combining the four parcels, razing the existing buildings, and construction of a four-story senior living apartment building with associated parking, access drives, and stormwater control measures. However, as previously noted, this EMP is for building demolition and UST removal solely at the 1402 Garner Road parcel The UST removal will be conducted in accordance with applicable UST Section guidance, with the exception that MADEP analyses will not be conducted on site samples. The work is being paid for via a one-year grant from the City of Raleigh pursuant to the American Rescue Plan Act of 2021 and the City's Community Health Initiative Capital Projects. At least two heating oil USTs remain at the 1402 Garner Road parcel. Specifically, the USTs are located south of the former convenience store building (Suspect UST #2) and west of the former automotive repair building (Suspect UST #3) as shown in Figure 2. The tank dimensions could range from approximately 5 to 10 ft long and about 4 ft wide, with capacities ranging from 500 to 1,000 gallons. Additionally, tank ventilation pipes, a fuel dispenser concrete island, and utility and/or product piping were observed in the southern and eastern portions of the parcel. As such, it is possible that a UST is or was present there (i.e., Suspect UST #1, Figure 2). H&H was unable to locate records pertaining to the three suspect UST contents. Once details associated with full redevelopment plans for the Brownfields property are available, those plans will be provided to the DEQ Brownfields Program for review in a revised EMP. We expect this will occur sometime in late 2024 to early 2025. 4) Do plans include demolition of structure(s)?: ® Yes ❑ No ❑ Unknown ® If yes, please check here to confirm that demolition will be conducted in accordance with applicable legal requirements, including without limitation those related to lead and asbestos abatement that are administered by the Health Hazards Control Unit within the Division of Public Health of the North Carolina Department of Health and Human Services. If available, please provide a copy of your demolition permit. The building improvements at the 1412 Garner Rd parcel and the warehouse at 500 Hoke St were demolished in early September 2023. A copy of the demo permit is provided with this EMP. Building slabs remain and the demo work did not entail ground disturbance. 5) Are sediment and erosion control measures required by federal, state, or local regulations?

PART 1. SOIL 1) Known or suspected contaminants in soil (list general groups of contaminants): Multiple environmental assessments have been conducted at the Brownfields Property. For the 1402 Garner Road portion, a site assessment, including soil testing, was conducted by Hart & Hickman (Brownfields Assessment Report, February 16, 2023). Figures 3 and 4 show soil sample locations and Tables 1 and 2 (attached) provide the analytical data from the H&H report. A summary of the soil assessment results for the 1402 Garner Road parcel is provided below. Volatile Organic Compounds (VOCs) Low levels of VOCs were detected above laboratory method detection limits in several soil samples. However, no VOCs were detected above the Residential or Industrial/Commercial PSRGs, including the samples collected adjacent to UST locations. Semi -Volatile Organic Compounds (SVOCs) Low levels of SVOCs, including polycyclic aromatic hydrocarbons, were detected in multiple soil samples above laboratory method detection limits. Benzo(a)pyrene (up to 0.496 milligrams per kilogram [mg/kg)), was detected above the Residential PSRG in soil samples SB-16, SB-22 and SB- 23. No other SVOCs were detected at above Residential or Industrial/Commercial PSRGs. Matnlc Naturally -occurring background levels of several metals were detected at concentrations above laboratory method detection limits. However, only arsenic, hexavalent chromium and lead were detected at concentrations above their respective Residential PSRGs. Arsenic and total chromium were detected at concentrations below and/or within published and site -specific background levels. Speciation of total chromium was performed to determine the hexavalent chromium (Cr6+) concentrations in soil. Cr6+ was measured above the Residential PSRG, but below the Industrial/Commercial PSRG. The Cr6+ found could be indicative of background conditions due to natural speciation of chromium between its trivalent and hexavalent valence states, and not associated with a release. Lead was detected in samples SB-20 (445 mg/kg) and SB-23 (950 mg/kg) at concentrations above the Residential PSRG, Industrial/Commercial PSRG (SB-23 only), and 20 times the hazardous characteristic threshold concentration. Results of Toxicity Characteristic Leaching Procedure (TCLP) analyses for SB-23 indicated lead at a concentration of 6.27 milligrams per liter (mg/L), which is above the Federal Toxicity Characteristic Level of 5 mg/L (40 CFR Subpart C 261.24). 8 EMP Version 3, March 2023 As mentioned below, we will limit soil disturbance when we remove the USTs and minimize soil removal from in and around the tank graves. All excavated soil will be removed and disposed offsite. Additional steps to minimize contact by future uses to impacted soils will be evaluated as part of the future development plans for the site. This EMP is solely for the upcoming UST removal work. 2) Depth of known or suspected contaminants (feet): Up to approximately 6 ft bgs. 3) Area of soil disturbed by redevelopment (square feet): USTs will be removed in a manner to limit surface disturbance to approximately 50 square ft (sq ft) or less. Otherwise, no other ground surface disturbance is planned. 4) Depths of soil to be excavated (feet): Minimal soil disturbance is expected to remove the USTs. Excavation depth will be limited to the base of the USTs, expected to be approximately 4-5 ft bgs. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Minimal (approximately 5 cubic yards [cy] or less) soil disturbance is expected to occur during the removal of the USTs. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Up to approximately 5 cy. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Soil disturbed during UST removal will be disposed of offsite at Triangle Area Earth, a licensed disposal facility, and will not be used as backfill for the UST excavation pits unless the soil is tested and shown to be below residential screening levels. There will be no mass grading or other ground disturbance associated with the UST removal work covered by this EMP. Future ground disturbance, grading, and foundation work for the apartment complex will be subject to a separate EMP. PART 1.A. MANAGING ONSITE SOIL If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields Property, or otherwise disturbed during site grading or other redevelopment activities, please provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are acceptable, if only preliminarydata 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). 9 EMP Version 3, March 2023 ❑ 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 POLICY,THE SOIL MAY NOT BE RE -USED ONSITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DEQ 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 Click or tap here to enter text. ❑ Corrosivity Click or tap here to enter text. ❑ Reactivity Click or tap here to enter text. ❑ Toxicity ick or tap here to enter text. ® TCLP results The results of the Toxicity Characteristic Leaching Procedure (TCLP) laboratory analyses indicated lead at a concentration of 6.27 mg/L in SB- 23, which exceeds the TCLP level of 5 mg/L defined in 40 CFR Subpart C 261.24. Lead -impacted soil excavated from in and around the SB-23 sampling location during the UST removal work will not be used as backfill. ® 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) Results of soil assessment indicated that lead in soil samples SB-20 (445 mg/kg) and SB-23 (950 mg/kg) at concentrations above the TCLP Rule of 20. However, the results of TCLP analyses indicated that the leachate concentration for soil sample SB-20 does not exceed toxicity characteristic levels for lead. ❑ If no, explain rationale: d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE SOIL MAYNOT BE RE -USED ONSITE 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) 10 EMP Version 3, March 2023 ❑ Site -specific risk -based cleanup level.

The demolition contractor will consider conditions such as wind speed and direction, and moisture content of soil during demolition and UST removal to minimize dust generation. In the unlikely event that contaminated soil requires excavation, contractors will implement dust control measures (e.g., controlled water application, hydro -seeding, and/or mulch, stone, or plastic cover). Impacted soil will be managed as described below. Field screenine of site soil At a minimum, contractors shall be made aware of protocols should impacted soils (e.g. staining, unusual odors, fill materials) be identified. 11 EMP Version 3, March 2023 Describe the field screening method, frequency of field screening, person conducting field screening: During UST removal work, the contractors will observe for evidence of potential impacted soil, such as a distinct unnatural color, strong odor, or filled or disposed materials (e.g., chemicals, tanks, drums, etc.). Should the above be noted, the contractor will contact the project environmental professional. If the project environmental professional confirms that the material may be impacted, the following procedures will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within two business days. 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 yd'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: Soil samples will be collected from the four sidewalls and base of the tank grave excavations prior to backfilling. The samples will be analyzed for VOCs, SVOCs, and RCRA metals, plus Cr6+. This phase of the project will not entail mass grading or other planned significant ground disturbance. We will be removing USTs and disposing of soil at Tringle Area Earth that we disturb from the tank graves. Additional soil testing will be completed as may be necessary to meet Triangle Area Earth's requirements.

Depths of disturbance will extend to the base of the USTs, which is expected to be approximately 4-8 ft bgs. 3) Is groundwater known to be contaminated by ❑onsite ❑offsite El both or El unknown sources? Describe source(s): Groundwater assessment activities conducted at the 1402 Garner Road parcel have indicated no VOCs, SVOCs, or metals at concentrations above Title 15A NCAC 2L Groundwater Standards (2L Standards). 4) What is the direction of groundwater flow at the Brownfields Property? Groundwater flow direction is to the south. 5) Will groundwater likely be encountered during planned redevelopment activities (e.g., footer/utility construction or helical pilings?) ❑Yes ®No If yes, describe these activities: In the event that groundwater is encountered during redevelopment activities (even if no is checked above), list activities for contingent management of groundwater (e.g., dewateringof groundwater from excavations or foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or sampling procedures). While unlikely if groundwater is encountered, the contractor will contact the environmental professional, who will update the DEQ Brownfields manager within two business days. Although not anticipated, appropriate worker safety measures to eliminate contact with groundwater (i.e., movement of workers away from the area and/or the use of personal protection equipment [PPE]) will be undertaken if groundwater gathers in an open excavation within an area determined to be impacted (based on strong odor, unnatural color, sheen, etc.). The accumulated water will be allowed to evaporate/infiltrate to the extent that time for dissipation does not disrupt the construction schedule. Should the time needed for natural dissipation of accumulated water be deemed to slow, the water will be tested for VOCs, SVOCs, and RCRA metals and disposed of off -Site (if impacted), or tested and discharged to the storm sewer (if not impacted above Title 15A NCAC 2B Surface Water Standards and not considered listed hazardous waste) in accordance with applicable City of Raleigh stormwater regulations. If free -flowing groundwater can be reasonably captured, it will be pumped to lined and covered roll -off containers or an aboveground tank prior to testing for VOCs, SVOCs, and RCRA metals. The groundwater will then be disposed of off -Site (if impacted) or discharged to the storm sewer (if not impacted above 2B Standards and not considered listed hazardous waste). 6) Are monitoring wells currently present on the Brownfields Property? ................. ❑Yes ®No If yes, are any monitoring wells routinely monitored through DEQ or other agencies?..................................................................................................................

CONTINGENCY PLAN 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, orother 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, 21 EMP Version 3, March 2023 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: ® 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): N VI LCIP I ICI C lV CI IICI MCA, ❑ Other Constituents & Analytical Method(s) (e.g. Herbicides) Please note, if field observations indicate the need for additional analyses, they should be conducted, even if not listed here. Click or tap here to enter text. Please provide details on the proposed methods of managing the following commonly encountered issues during redevelopment of Brownfields Properties. Underground Storage Tanks — Note that UST Section guidelines must be followed for sample frequency during UST closure. Unless damage to onsite structures to remain as part of redevelopment would occur, USTs shall be removed from the Brownfields Property: If an additional UST(s) is encountered, the environmental professional will be consulted to determine the appropriate course of action. In addition, the DEQ project manager will be informed. The UST will be removed and disposed, and the area in the vicinity of the UST assessed for evidence of a release. The sampling protocol will include analysis of soil samples for VOCs, SVOCs, RCRA metals and Cr (VI) to allow for risk -based decision making. The other procedures outlined above for the planned UST removal work will be followed. Sub -Grade Feature/Pit: If a sub -grade feature or pit is encountered, DEQ Brownfields will be notified, and the feature or pit will be filled with soil or suitable fill. Where appropriate, the bottom may be penetrated before backfilling to prevent fluid accumulation. 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 pit must be removed and the observed waste characteristics indicate the concrete may potentially be contaminated, the concrete will be sampled and analyzed by methods specified by the disposal facility. Confirmatory soil samples below the pit (sidewalls and base) will be collected. Buried Waste Material — Note that if buried waste, non-native fill, or any obviously filled materials is encountered, the DEQ Brownfields Redevelopment Section must be notified to determine if investigation of landfill gases is required: If excavation into buried wastes or impacted soils occurs, the contractor is instructed to stop work in that location and notify the environmental consultant, who will then notify the DEQ Brownfields 22 EMP Version 3, March 2023 Program. The environmental consultant will review the materials and collect samples and/or conduct soil gas monitoring. Confirmation sampling will be conducted at representative locations in the base and the sidewalls of the excavation after the waste or impacted soil is removed. The confirmation samples will be analyzed for VOCs, SVOCs, and RCRA metals. Areas of suspected contaminated soil that remain after excavation is complete above the DEQ Residential PSRGs will be managed pursuant to this plan. Re -Use of Impacted Soils Onsite: Please refer to the description outlined in the Managing On -Site Soil section of the EMP above. If unknown, impacted soil is identified onsite, management onsite 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 onsite. If other potential contingency plans are pertinent, please provide other details or scenarios as needed below: POST -REDEVELOPMENT REPORTING ® Check this box to acknowledge that a Redevelopment Summary Report will be required for the project. If the project duration is longer than one year, an annual update is required and will be due by January 31 of each year, or 30 days after each one-year anniversary of the effective date of this EMP (as agreed upon with the project manager). These reports will be required for as long as physical redevelopment of the Brownfields Property continues, except that the final Redevelopment Summary Report will be submitted within 90 days after completion of redevelopment. Based on the estimated construction schedule, the first Redevelopment Summary Report is anticipated to be submitted on 1/31/2024 The Redevelopment Summary Report shall include environment -related activities since the last report, with a summary and drawings, that describes: 1. actions taken on the Brownfields Property; 2. soil grading and cut and fill actions; 3. methodology(ies) employed for field screening, sampling and laboratory analysis of environmental media; 4. stockpiling, containerizing, decontaminating, treating, handling, laboratory analysis and ultimate disposition of any soil, groundwater or other materials suspected or confirmed to be contaminated with regulated substances; and 5. removal of any contaminated soil, water or other contaminated materials (for example, concrete, demolition debris) from the Brownfields Property (copies of all legally required manifests shall be included).
