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. 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): A tabular summary of soil analytical data in comparison to the July 2023 North Carolina Department of Environmental Quality (DEQ) Residential and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) is included as Table 1. Soil sample locations are shown on Figures 2 and 3A. A brief summary of the results is provided below. Volatile Organic Compounds (VOCs) and Semi‐Volatile Organic Compounds (SVOCs) Volatile organic compounds (VOCs) have not been detected in soil samples at concentrations above Residential or Industrial/Commercial PSRGs. TCE was not detected above the laboratory method detection limits (MDLs) in any soil samples collected from the site. The polynuclear aromatic hydrocarbons (PAHs) benzo(a)anthracene (up to 12.3 milligrams per kilogram [mg/kg]), benzo(a)pyrene (up to 9.14 mg/kg), benzo(b)fluoranthene (up to 13.2 mg/kg), dibenz(a,h)anthracene (up to 2.27 mg/kg), and/or indeno(1,2,3‐cd)pyrene (5.63 mg/kg) were detected in composite soil samples CS‐1, CS‐2 and its duplicate (SB‐DUP), and CS‐7 at concentrations above the Residential PSRGs of 1.1 mg/kg, 0.11 mg/kg, 1.1 mg/kg, 0.11 mg/kg, and 1.1 mg/kg, respectively. The detected concentrations of benzo(a)pyrene and dibenz(a,h)anthracene in soil sample CS‐1 also exceed the Industrial/Commercial PSRGs of 2.1 mg/kg and 2.1 mg/kg, respectively. No other SVOCs have been detected above Residential or Industrial/Commercial PSRGs in soil samples collected at the site. Metals Hexavalent chromium was detected in soil samples CS‐1 through CS‐7 collected in areas of proposed buildings at concentrations exceeding the Residential PSRG of 0.31 mg/kg but below the Industrial/Commercial PSRG of 6.5 mg/kg. The detected hexavalent chromium concentrations are generally consistent with site‐specific background concentrations and concentrations detected at numerous properties across North Carolina, including undeveloped properties. Arsenic was also detected above the Industrial/Commercial PSRGs in samples CS‐1 through CS‐7. However, the arsenic detections are generally consistent with site‐specific background concentrations and are within the range of published regional background levels. The detected hexavalent chromium and arsenic concentrations are likely naturally occurring. Polychlorinated Biphenyls (PCBs) 9 EMP Version 3, March 2023 No PCBs were detected at concentrations above the MDLs in sample SG‐3 (1‐3 ft), which was collected at a former electrical substation in the central portion of the Brownfields property. 2) Depth of known or suspected contaminants (feet): Soil impacts have been confirmed at depths of approximately 0‐2 feet below ground surface (bgs). 3) Area of soil disturbed by redevelopment (square feet): Based on the cut/fill plans provided in Appendix B, approximately 15 acres (653,400 square feet) of the 17.45‐acre site is expected to be disturbed during grading and construction activities. Areas excluded from disturbance include wooded land and portions of an electrical powerline right‐of‐way in the northwestern portion of the site and portions of a railroad right‐of‐way in the southern portion of the site. 4) Depths of soil to be excavated (feet): Planned cut depths as part of mass grading are expected to range from approximately 0.5 to 10 ft below current grade elevations. Additional excavation within a similar depth range is anticipated at proposed utility trenches, building foundations, and stormwater/sediment basins. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Grading activities for the proposed redevelopment at the site will generate approximately 19,700 cubic yards of cut and approximately 23,870 cubic yards of fill to achieve proposed final grade elevations. To the extent possible, cut material will be reused as fill if the material is structurally suitable. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: The volume of impacted soil to be excavated at the site is unknown. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: See answer to Part 1 Section 6 above. Soil management (including potential off‐site disposal) will be based on stockpile soil sample analytical data and risk evaluation by the Brownfields Redevelopment Section if excess soil cannot be re‐used as fill material. PART 1.A. MANAGING ONSITE SOIL If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields Property, or otherwise disturbed during site grading or other redevelopment activities, please provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are acceptable, if only preliminary data available). 1) HAZARDOUS WASTE DETERMINATION: 10 EMP Version 3, March 2023 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 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 ☐ Corrosivity Click or tap here to enter text. ☐ Reactivity Click or tap here to enter text. ☐ Toxicity Click or tap here to enter text. ☐ TCLP results Click or tap here to enter text. ☐ 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: Based on results of soil assessment activities and the “Rule of 20”, no compounds have been identified at characteristically hazardous levels. d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE SOIL MAY NOT 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) ☐ Site‐specific risk‐based cleanup level. Please provide details of methods used for 11 EMP Version 3, March 2023 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 onsite map to Brownfields project manager once known. ☒ Geotextile to mark depth of fill material. Provide description of material: The use of a geotextile is not planned but will be considered. ☒ Manage soil under impervious cap ☒ or clean fill ☒ ☒ Describe cap or fill: Should potentially impacted soil or fill materials be encountered during redevelopment that do not require removal for geotechnical or construction purposes, the potentially impacted soil may be placed beneath impervious surfaces (asphalt pavement, sidewalks, access roads, buildings, etc.) or a minimum of 2 ft of clean 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: ☒ Check to confirm that management of fugitive dust from site activities will be handled in accordance with applicable local, state, and federal requirements. Field screening 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. Describe the field screening method, frequency of field screening, person conducting field screening: During soil disturbance at the site, the workers or contractors will observe 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., 12 EMP Version 3, March 2023 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. Soil sample collection ☒ Yes The PD may perform in‐situ composite or stockpile sampling to characterize soil for export purposes. The proposed methodology and scope of work for in‐situ soil sampling will be outlined in a Work Plan, which will be submitted to DEQ for approval prior to conducting in‐situ composite sampling activities. Stockpile soil sampling will consist of 3‐point composite samples and a grab sample for VOC analysis as specified in Part 1.C. (Soil Export). ☒ 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: If impacted soil is encountered during grading and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading or other construction‐ related activity to continue and/or only as far as needed to allow alternate corrective measures as described below. Suspect 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 soil sample (no less than 3 aliquot soil samples) at a sample ratio of 1 soil sample per every approximately 500 cubic yards of soil will be collected for analysis of total VOCs, SVOCs, RCRA metals, and hexavalent chromium. If the soil sample laboratory analytical results indicate that the soil could potentially exceed toxicity characteristic hazardous waste criteria, then the soil will also be analyzed by TCLP for those compounds that could exceed the toxicity characteristic hazardous waste criteria. Impacted soil will be handled in the manner described below based upon the laboratory analyses: i. If no organic compounds or metals are detected in a sample (other than which are attributable to sampling or laboratory artifacts or which are consistent with background levels for metals) above protection of groundwater or Residential PSRGs (whichever is lower for the detected compounds), the TCLP concentrations are below hazardous waste criteria, and the cumulative risk calculator results are acceptable, then the soil will be deemed suitable for use as on‐site fill or as off‐ site fill with DEQ approval. The proposed location(s) for off‐site placement of soil 13 EMP Version 3, March 2023 (other than a Municipal Solid Waste Landfill [MSWLF] or other 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 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 may be used on‐site as fill without conditions. 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 demonstrably clean soil, or overlain by a geotechnical fabric and at least 1 ft of demonstrably clean soil. If the impacted soil with concentrations above Industrial/Commercial PSRGs is moved to an on‐site location, its location and depth will be documented and provided to DEQ and the impacted soil will be placed beneath at least 2 ft of compacted demonstrably clean soil, an impervious surface, or covered by a geotechnical fabric. iv. Impacted soil may be transported to a MSWLF or DEQ permitted landfarm provided that the soil is accepted at the disposal facility. DEQ Solid Waste Section and DEQ Brownfields Redevelopment Section approval will be requested for any potential export to an off‐Site facility other than a MSWLF or DEQ permitted landfarm. If soil is transported to a MSWLF or DEQ permitted landfarm, the facility’s written approval in the form of waste manifests or similar will be included with the annual 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 MSWLF that can accept or treat hazardous waste. * Please note that should the PD elect to transport export soil to a MSWLF, DEQ permitted landfarm, or to a DEQ Brownfields pre‐approved receiving facility, soil will be direct‐loaded onto trucks for transport off‐site. 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): ☐ PCBs: Specify Analytical Method Number(s): 14 EMP Version 3, March 2023 ☐ Other Constituents & Respective Analytical Method(s) (e.g. Herbicides): ☒ 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. If impacted soils above applicable PSRGs and/or site specific risk thresholds are proposed to be relocated on‐site, prior to final placement on‐site, the following shall be submitted for DEQ review/approval ‐ Analytical data that has been sampled in accordance with the above referenced 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) ‐ Figure outlining planned soil placement and any future site features including buildings/hardscape/open areas ‐ A North Carolina PE/PG recommendation of placement Impacts Options Onsite Placement without conditions Onsite placement under 2 ft of cap or clean fill1, 2 All Constituents below applicable PSRGs X Constituents3 below applicable PSRGs; Metals below background but above PSRGs X Constituents3 below applicable PSRGs; Metals above Background /PSRGs X Constituents above Applicable PSRGs X 1: Requires Prior Written DEQ Approval 2: VOC impacted soils above applicable PSRGs shall not be placed directly beneath building footprints without prior written DEQ approval. 3: Constituents indicate any samples evaluated for other than metals. ☒ 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: 15 EMP Version 3, March 2023 ☒ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or permanent hardscape).

Samples should be collected from 0‐2 ft below ground surface, with the exception of VOCs which should be taken from 1‐2 ft below ground surface. Alternatively, indicate if a work plan for final grade sampling may be submitted under separate cover. A Final Grade Sampling Plan will be prepared following review of final landscape/hardscape plans for the site. The work plan will be submitted to DEQ Brownfields Redevelopment Section under separate cover. If no areas exist that warrant final grade sampling, documentation will be provided to the DEQ Brownfields project manager and/or the DEQ Brownfields Property Management Unit. ☐ If final grade sampling was NOT selected, please explain rationale: PART 1.B. IMPORTED FILL SOIL NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL FROM THE BROWNFIELDS REDEVELOPMENT SECTION. 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 Redevelopment Section), 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: ☒ Check to confirm that the import volumes outlined below have been confirmed based on geotechnical evaluations. 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? Approximately 4,200 cubic yards of fill will need to be imported into the site for mass grading activities during redevelopment of the Brownfields property. 16 EMP Version 3, March 2023 3) If yes, what is the anticipated depth that fill soil will be placed at the property?

North‐northwest in the northern portion of the site and likely south‐southwest in the southern portion of the site. 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: Based on the depth to groundwater data and preliminary grading plans, it is not anticipated that groundwater will be encountered during planned redevelopment 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., 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 (based on previous sampling data, strong odor, unnatural color, sheen, etc.) during construction activities. The contractor will contact the environmental professional to observe the area(s) suspected to be impacted. The accumulated water will be allowed to evaporate/infiltrate to the extent 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 for the presence of VOCs, SVOCs, and RCRA metals 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. Equipment that has been in contact with saturated soil will be cleaned before leaving the Brownfields Property. 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?..................................................................................................................☐Yes ☐No 7) 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 Redevelopment Section’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. 8) Please provide additional details as needed: 21 EMP Version 3, March 2023 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.

VIMS Plan shall be signed and sealed by a NC Professional Engineer and follow the DEQ Brownfields Redevelopment Section’s Vapor Intrusion Mitigation System Design Submittal Requirements. Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors are identified or workers report lightheadedness or other unusual physical reaction) during future redevelopment activities, the area will be evacuated, and appropriate safety screening of the indoor air will be performed. If warranted, safety screening procedures will include periodically screening indoor air for volatile organic vapors with a calibrated PID. If results indicate further action is warranted, appropriate engineering controls (such as use of industrial fans) will be implemented. 24 EMP Version 3, March 2023 use restrictions or requirements of the recorded or draft Brownfields Agreement and that separate approval of mitigation measures will be required. 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, 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: ☒ 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): ☐ PCBs: Specify Analytical Method Number(s): ☐ 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. 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: 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 Redevelopment Section. DEQ Brownfields will be notified within 48 hours of discovery of the UST. If an undocumented UST is encountered, residual fluids (if present) will be removed, sampled for 25 EMP Version 3, March 2023 VOCs, SVOCs, and RCRA metals, and transported off‐site for disposal at a suitable facility based on the laboratory analytical results. Following the removal of residual fluids, the tank will be removed, and closure soil sampling will be performed. The number of soil samples will be consistent with DEQ UST Section guidelines. The soil samples will be submitted for laboratory analysis of VOCs, SVOCs, RCRA metals, and hexavalent chromium. Impacted soil will be managed in accordance with the Managing On‐Site Soil (Part 1.A.) section outlined above. If the UST cannot be removed for geotechnical or construction purposes, DEQ will be notified for approval of in‐place closure. Following DEQ approval, closure soil sampling will be performed in general accordance with the DEQ UST Section guidelines. Where appropriate, the bottom of the UST may be penetrated before abandonment to prevent fluid accumulation. If the UST contains residual fluids, the fluids will be removed, sampled for VOCs, SVOCs, and RCRA metals, and transported off‐site for disposal at a suitable facility based on the laboratory analytical results. A survey plat update may also be needed in the event of in‐place closure of USTs. 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 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 (Part 1.A.) section outlined above, 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 Redevelopment Section 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 observe the suspect 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, RCRA metals, hexavalent chromium (or other analyses as appropriate based on the type of waste material). Information will be provided to DEQ Brownfields regarding the permitted facility used for disposal of the waste or significantly impacted soil. Areas of suspected contaminated soil that remain at the site after excavation is complete above the DEQ Residential PSRGs will be managed pursuant to this plan. Re‐Use of Impacted Soils Onsite: Please refer to description outlined in the Managing On‐Site Soil section (Part 1.A.) of the EMP 26 EMP Version 3, March 2023 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.
