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. 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.

This EMP pertains to modifications of the existing building slab that are necessary as part of the operational upfits. 2) Check the following activities that will be conducted prior to commencing earth moving activities at the site: Review of historic maps (Sanborn Maps, facility maps) Conducting geophysical surveys to evaluate the location of suspect UST, fuel lines, utility lines, etc. A subcontract utility locate will be engaged to conduct a ground penetrating radar (GPR) survey in the areas of proposed disturbance prior to saw cutting of the building foundation slab to determine if sub-grade utilities are present. If potential utilities are identified in the proposed excavation areas, alternate excavation methodology (e.g. soft dig, air-knife) may be implemented to safely lower the grade to the necessary depth to accommodate the desired new slab thickness (see item 3 below). If the GPR survey identifies a suspect UST, the Brownfields Project Manager will be contacted to discuss follow up actions that may be necessary. Interviews with employees/former employees/facility managers/neighbors 3) Summary of Redevelopment Plans (MANDATORY: attach detailed plans or conceptual plans, if detailed plans are not available. 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: Dura Supreme Cabinets (Dura) is engaging in a lease agreement with the Follow-On Owner (GTIS Partners) of the Brownfields Property to occupy the on-site facility. Dura proposes to complete interior upfits of the facility building to accommodate its planned manufacturing activities. Among these upfits are renovations to 40 discrete areas of the building foundation slab, as shown in Figure 2. The purpose of the slab renovations is as follows: 7 EMP Version 3, March 2023 1) To fill former equipment pits with crushed virgin stone and install new slab to bring these areas up to the same finished grade as the surrounding floor (x 3; shown in red on Figure 2); 2) To repair areas where the slab is cracked via replacement of the concrete (x 32; shown in black on Figure 2; three of the repair areas coincide with planned isolation pads); and 3) To create vibration isolation pads for planned heavy manufacturing equipment (x 8; shown in red on Figure 2; three isolation pads coincide with areas slated for repair) The first of these tasks will not involve ground disturbance or result in worker contact with on- site soils. Sub-slab soils likely will be encountered during execution of the latter two tasks, as soils will likely be stuck to the underside of the concrete to be removed and, depending on the thickness of the slabs removed, soil may require excavation to allow for the replacement slab to be 6-inches thick (in the case of task number 2) and 8-inches thick (in the case of task number 3). 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. 5) Are sediment and erosion control measures required by federal, state, or local regulations? S&EC requirements can be found at: https://deq.nc.gov/about/divisions/energy-mineral-and-land- resources/erosion-and-sediment-control/erosion-and-sediment-control-laws-and-rules Yes No Unknown If yes, please check here to confirm that earth-work will be conducted in accordance with applicable legal requirements. If soil disturbance is necessary to install sediment and erosion control measures, they may not begin until this EMP is approved. 6) Which category of risk based screening level is used or is anticipated to be specified in the Brownfields Agreement? Note: If children frequent the property, residential screening levels shall be cited in the Brownfields Agreement for comparison purposes. Residential Non Residential or Industrial/Commercial 7) Schedule for Redevelopment (attach construction schedule): a) Construction start date: 4/7/2023 b) Anticipated duration (specify activities during each phase): Approximately 2 months 8 EMP Version 3, March 2023 c) Additional phases planned? Yes No While additional redevelopment phases are not planned at this time, the procedures and protocols included within this EMP shall be applicable to potential future planned phases of ground disturbance associated with building foundation slab modifications.

Sediment: .......................................... Yes No Suspected Unknown N/A Part 5. Soil Vapor: ......................................... Yes No Suspected Unknown Part 6. .......................... Yes No Suspected Unknown Part 7. Indoor Air: ......................................... Yes No Suspected Unknown 9 EMP Version 3, March 2023 2) For the Area of Proposed Redevelopment on the Brownfields Property, attach tabulated data summaries for each impacted media and figure(s) with sample locations. Impacted environmental media has not been identified in the areas of proposed soil disturbance. Impacted media identified at the site are documented in Tables A and B of the Notice of Brownfields Property, Appendix A. Copies of the NBP and associated Plat Map showing the sample locations are provided as an attachment to this EMP. PART 1. SOIL 1) Known or suspected contaminants in soil (list general groups of contaminants): Soil in portions of the site is known to be impacted above applicable standards for lead and chromium. The soil impacts identified are limited to the northwestern portion of the building, in the vicinity of a former plating line used in the former furniture manufacturing operations on site. Additional soil impacts above applicable standards have not been identified. 2) Depth of known or suspected contaminants (feet): Approximately 2 feet below land surface (bls) 3) Area of soil disturbed by redevelopment (square feet): Approximately 13,933 square feet of soil will be exposed after the slab has been saw cut. 4) Depths of soil to be excavated (feet): The exact depths of soil to be excavated from the saw cuts is not known. The client requires an at least 6-inch-thick slab in the areas of concrete requiring repair due to cracks and at least an 8- inch-thick slab in areas where the vibration isolation pads are to be installed. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): The areas of proposed soil excavation are shown on Figure 2. Boring logs from a prior environmental report completed in 2003 by others reported slab thicknesses in eastern portion of the on-site warehouse (near Isolation Pads shown in red and numbered 16 through 18) of 6 and 8 inches. It is not known whether the slab in other portions of the building similarly thick. Conservatively assuming that the existing building slab is 4-inches thick, to provide the necessary new slab thicknesses, the soils underlying the areas of concrete repair will require excavation to a depth of 2 inches below base of existing concrete, while the areas in which the vibration isolation pads will be installed will require excavation to a depth of 4 inches below base of existing concrete. Based on the above assumptions, approximately 121.5 cubic yards of soil will be excavated from the beneath the slab. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Existing analytical data has not identified impacted soils in the areas of proposed disturbance; however, it is unknown whether impacted soils will be encountered during excavation. 10 EMP Version 3, March 2023 7)Estimated volumeof contaminated soil expected to be disposed of offsite, if applicable: The excavated soils are planned for either re-use on site (if analytical data from sampling of the temporary stockpile see Section Part 1A below indicates concentrations are suitable for re- use) or disposed off-site to an appropriately permitted facility (as discussed in Part 1C). Figure 3 shows the proposed area of re-use for the soils, if the data indicates re-use is acceptable. 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: a) Does the soil contain a LISTED WASTE as defined in the North Carolina Hazardous Waste Section under 40 CFR Part .......................................

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: Based on the prior site investigation results, the contaminants of concern at the site are metals. As such, personal environmental monitors (PEM) will be utilized to screen ambient air for particulate matter below 10 micrometers in diameter. Should a PEM identify particulate matter below this diameter, work shall be stopped temporarily and will not begin until field screening indicates particulate matter in the work area has returned to a safe level. Should it be necessary to continue work, temporary mitigation measures (e.g. application of clean water to the soils to tamp down dust, mechanical ventilation, or the use of PPE for site workers, etc.) may be implemented. While it is not anticipated that construction workers will encounter volatile vapors from beneath the slab during the renovation work. However, as a precautionary measure, Terracon will also utilize a PID to screen ambient air for volatile organic compounds (VOCs). If PID readings greater than 25 parts per million (ppm) greater than background levels are identified, work will be temporarily stopped so that further evaluation can be conducted. Work will not begin again until the vapor field screening indicates concentrations have returned to background levels. If necessary to continue work, temporary mitigation measures (e.g. mechanical ventilation, air purifying units, the use of PPE for site workers, etc.) may be implemented. possible presence of contaminated soil vapors in excavations beneath the slab. If during construction, workers identify evidence of elevated vapor concentrations (odor, lightheadedness, etc.) regardless of PID readings, work will be stopped until it is determined that it is safe to proceed. Soil sample collection Yes 13 EMP Version 3, March 2023 Soils excavated from beneath the slab to accommodate the foundation upfits will be temporarily stockpiled within the building in accordance with Figure 1. The stockpile will be sampled in accordance with the protocols outlined below. 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: Based on the assumed depths of excavations described above, it is anticipated that the soil stockpile will be approximately 121.5 cubic yards in volume. As such, one composite soil sample will be collected from the stockpile using a decontaminated hand auger in accordance with the sampling procedures outlined in the NCDEQ Inactive Hazardous Site 2020). The sample will be composited from three to five individual locations by advancing the hand auger approximately 2 feet into the stockpile at each location. The soils from each 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 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 bags (placed on ice) from each set of borings will then be composited using a decontaminated stainless-steel bowl and spoon via the sample homogenization procedures outlined in the U.S. Environmental PROC-300-R3 (June 11, 2020) guidance. The sample will be analyzed for VOCs (8260), SVOCs (8270), RCRA 8 Metals (6010/7471), and hexavalent chromium (7199), as noted below. In addition to the grab (VOC) and composite sample (other analyses), Terracon will also collect the following samples for quality assurance/quality control purposes: one field/equipment blank (collected by rinsing deionized water over the bucket of the hand auger and the mixing bowl and collecting the rinsate in laboratory-supplied glassware; sample to be analyzed for VOCs only), one blind duplicate sample analyzed for the full suite of analyses, and one matrix spike/matrix spike-duplicate sample analyzed for the full suite of analyses. 14 EMP Version 3, March 2023 A Level II QA/QC package will be requested from the laboratory, whose reporting and method detection limits will meet applicable screening criteria to the extent technologically feasible. The analytical report will include the use of J-flags for estimated concentrations.

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 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 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 64 cubic yards of virgin, crushed stone material will be imported from the Martin Marietta Statesville quarry in order to fill three former concrete-lined equipment pits (see blue areas outlined on Figure 2) and bring the base up to grade so that concrete may be poured flush with the surrounding slab. Per DEQ during a March 7, 2023 meeting, this crushed stone will not require characterization prior to import. 3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range of depths, list the range.) The equipment pits in question are approximately 3 feet below the top of the existing concrete slab. The crushed stone will be placed within the pits to approximately 6-inches below the top of the slab and then topped with new concrete. 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: Click or tap here to enter text.

Groundwater flows toward the north/northeast. 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: Click or tap here to enter text. 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). Should groundwater be encountered within an excavation, it will be allowed to re-infiltrate for approximately 24 hours, if it does not affect the construction schedule. If the groundwater must be removed so that construction activities may proceed, the groundwater will be pumped into a tanker or aboveground storage containers for temporary containerization. Terracon will contact DEQ to determine an appropriate course of action, which may include sampling of the containerized water to determine proper management and/or disposal. 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 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: The existing monitoring wells (MW-4, MW-6, MW-7, and MW-8) are located outside, along the northern exterior wall of the building, as depicted in Figure 3. The proposed slab renovations will occur on the interior of the southern portion of the building and will not impact the monitoring wells. 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. SURFACE WATER 1) Is surface water present at the property? Yes No 2) If yes, attach a map showing the location of surface water at the Brownfields Property 3) Is surface water at the property known to be contaminated? Yes No Unknown 4) Will workers or the public be in contact with surface water during planned redevelopment activities or as part of the final redevelopment? Yes No 5) In the event that contaminated surface water is encountered during redevelopment activities, or clean surface water enters open excavations, list activities for management of such events (e.g. flooding, contaminated surface water run off, stormwater impacts): Not applicable. Surface water has not been identified on the site. PART 4. SEDIMENT 1) Are sediment sources present on the property? Yes No 2) If yes, is sediment at the property known to be contaminated? Yes No Unknown 3) Will workers or the public be in contact with sediment during planned redevelopment activities? Yes No 4) Attach a map showing the location of known contaminated sediment at the property. 5) In the event that contaminated sediment is encountered during redevelopment activities, list activities for management of such events (stream bed disturbance): Not applicable.

Yes No Unknown In the event that apparent contaminated soil vapor is encountered (based on elevated PID readings, unusual odors, etc.) during redevelopment activities (trenches, manways, basements or other subsurface work,) list activities for management of such contact, INCLUDING notification to DEQ within 48 hours of identification of the issue for determination of additional requirements: Based on the prior site investigation results, the contaminants of concern at the site are metals. As such, it is not anticipated that construction workers will encounter volatile vapors from beneath the slab during the renovation work. However, as a precautionary measure, Terracon will be on-site during construction to provide ambient air screening services. Terracon will utilize a PID to screen ambient air during the slab cuts and soil excavation work. Field screening with a PID will be conducted during operation of petroleum-fueled equipment utilized to complete the slab modifications (e.g. excavator, concrete-saw, skid-steers, etc.) to establish a background VOC concentration. This background concentration may vary with time depending on the types and amount of equipment in use at any given time. Terracon will update the apparent background concentration on an as needed basis during the slab modifications and record the concentration in its field documentation. If PID readings greater than 25 parts per million (ppm) above background levels are identified, work will be temporarily stopped so that further evaluation can be conducted. Work will not begin again until the vapor field screening indicates concentrations have returned to background levels. If necessary to continue work, temporary mitigation measures (e.g. mechanical ventilation, air purifying units, the use of PPE for site workers, etc.) may be implemented. presence of contaminated soil vapors in excavations beneath the slab. If, during construction, workers identify evidence of elevated vapor concentrations (odor, lightheadedness, etc.) regardless of PID readings, work will be stopped until it is determined that it is safe to proceed. DEQ will be notified of any work stoppages and mitigation measures implemented at the site within 48 hours of their occurrence to discuss additional requirements that may be necessary.

VIMS Plan shall be signed and sealed by a NC Professional Engineer and follow the DEQ Vapor Intrusion Mitigation System Design Submittal Requirements. Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land use restrictions or requirements of the recorded or draft Brownfields Agreement and that separate approval of mitigation measures will be required. CONTINGENCY PLAN 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; 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 & 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: 25 EMP Version 3, March 2023 Should a UST(s) and/or related infrastructure be encountered during redevelopment activities, the environmental manager (Terracon) will be contacted immediately, and the identified item should remain as encountered. The DEQ Project Manager will be notified by the environmental manager for the site within 48 hours of discovery. Following notification of the Brownfields Project Manager, the UST or other containers will be removed from the ground after potential combustible vapors have been stabilized. Residual fluids, if present, will be removed and sampled for VOCs, SVOCs, and RCRA 8 metals. The fluids will be transported off-site for disposal at a suitable facility based on the laboratory analytical results. The UST will be hauled to an off-site facility for proper disposal and soil samples will be collected from the location of the UST and analyzed for VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D) and RCRA metals (EPA Methods 6010D and 7471B), in accordance with the applicable DEQ UST Guidance and Brownfields Program protocols. Impacted soil, if On- as outlined above. Documentation of the UST/container removal activities, UST disposal, and sampling results will be provided to the Brownfields Project Manager upon receipt by the environmental manager. Sub-Grade Feature/Pit: If during redevelopment activities, an unknown sub-grade feature/pit is encountered, the environmental manager will be notified immediately. The environmental manager (Terracon) will screen soils adjacent to the feature for potential impacts. Please note that this field screening will not be used to guide additional excavation and will be completed solely to assess possible risk implications associated with those potential impacts. The minimum amount of soil excavation d slab thicknesses will be conducted. The sub-grade feature will not be removed if it is not necessary to do so in order to achieve the desired slab thickness or to provide adequate structural support for the planned overlying slab. If necessary, a pit remaining in place will be filled with virgin crushed stone in accordance with the protocols listed in Part 1B above. If water is encountered within a sub-grade pit, the procedures outlined in Part 2 will be followed. If potential impacts are identified, the Brownfields Project Manager will be notified to discuss whether the apparent nature of the impacts necessitates additional actions. 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: The below described protocols apply only to debris encountered during construction. Per Brownfields requirement, due to the planned re-use, if debris is encountered, it must be removed. If during redevelopment activities, buried waste materials are encountered, the environmental manager (Terracon) will be notified immediately, and the identified waste should remain as encountered. The Brownfields Project Manager will be notified by the environmental manager within 24 hours of the environmental manager being notified. Following notification of the 26 EMP Version 3, March 2023 Brownfields Project Manager, the environmental manager will supervise exploratory excavation activities near the waste and soils will be screened for potential impacts. The type of field screening (i.e. for VOCs, for methane, etc.) will be determined by the apparent nature of the debris and conversations with the DEQ Project Manager. The waste will be segregated from surrounding soils, inventoried and evaluated for proper management. If potential impacts are identified, the Brownfields Project Manager will be notified, and soil samples will be collected from the area of potential impacts and analyzed for VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D) and RCRA metals (EPA Methods 6010D and 7471B). The sample frequency will be determined based on the nature of the debris and will be discussed with the Brownfields Project Manager prior to the collection of the samples, and a determination will be made regarding the need for an investigation of landfill gases. Additional laboratory analyses may be required based on the types of waste discovered. The location of the debris will be recorded for future reference. Documentation of the waste management activities and sampling results will be provided to the Brownfields Project Manager upon receipt by the environmental manager. Re-Use of Impacted Soils Onsite: Impacted soils will not be reused on site. If the stockpile sampling determines the excavated soils are impacted, the soils will be disposed of off-site to an appropriate permitted facility in accordance with the protocols outlined in Part 1C 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.
