The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify actions to be taken during the demolition and construction at Brownfields properties in an effort to avoid delays in the event of the discovery of new contamination sources or other environmental conditions. The EMP provides a means to document redevelopment plans and environmental data for each applicable environmental medium to inform regulatory-compliant decision-making at the site. As much detail as possible should be included in the EMP, including contingency planning for unknowns. Consult your project manager if you have questions. Prospective Developers and/or their consultants must complete and submit this form and all pertinent attachments, see checklist below, to their Brownfields project manager prior to any earthmoving or other development-related activities that have the potential to disturb soil at the Brownfields Property, including demolition. For the resultant EMP to be valid for use, it must be completed, reviewed by the program, signed by all parties working on the project, and approved by the Brownfields project manager. Failure to comply with the requirements of the EMP could jeopardize project eligibility, or in the event of a completed agreement, be cause for a reopener So that the EMP provides value in protecting brownfields eligibility and public health, the preparer shall ensure that the following steps have been completed prior to submitting the EMP for review. Any EMP prepared without completing these steps is premature. ☒ Site sampling and assessment that meets Brownfields’ objectives is complete and has been reviewed and approved by the Brownfields Project Manager. ☒ Specific redevelopment plans, even if conceptual, have been developed for the project, submitted and reviewed by the Brownfields Project Manager. 2 EMP Version 2, June 2018 Please submit, along with the completed EMP form, the following attachments, as relevant and applicable to the proposed redevelopment: ☒ A set of redevelopment plans, including architectural/engineering plans, if available; if not conceptual plans may suffice if updated when detailed plans are drafted. ☐ A figure overlaying redevelopment plans on a map of the extent of contamination for each media. ☐ Site grading plans that include a cut and fill analysis. ☐ A figure showing the proposed location and depth of impacted soil that would remain on site after construction grading. ☐ Any necessary permits for redevelopment (i.e. demolition, etc.). ☐ A detailed construction schedule that includes timing and phases of construction. ☒ Tabulated data summaries for each impacted media (i.e. soil, groundwater, soil gas, etc.) applicable to the proposed redevelopment. ☒ Figures with the sampling locations and contamination extents for each impacted media applicable to the proposed redevelopment. ☐ A full final grade sampling and analysis plan, if the redevelopment plan is final. ☐ If known, information about each proposed potential borrow soil source, such as aerial photos, historic site maps, historic Sanborn maps, a site history, necessary for brownfields approval. ☐ Information and, analytical data if required, for quarries, or other borrow sources, detailing the type of material proposed for importation to the Brownfields Property. ☐ A work plan for the sampling and analysis of soil to be brought onto the Brownfields Property. Refer to Issue Resolution 15 in Brownfields Program Guidelines. ☐ A map of the Brownfields Property showing the location of soils proposed for export and sampling data from those areas. ☐ If a Vapor Mitigation System is required by the Brownfields Program, the Vapor Intrusion Mitigation System (VIMS) plan will be signed and sealed by a NC Professional Engineer. The VIMS Plan may also be submitted under separate cover. 3 EMP Version 2, June 2018 GENERAL INFORMATION Date: 7/10/2019 Revision Date (if applicable): Click or tap to enter a date.

PART 1. Soil – Please fill out the information below, using detailed site plans, if available, or estimate using known areas of contaminated soil and a conceptual redevelopment plan. Provide a figure overlaying new construction onto figure showing contaminated soil and groundwater locations. 1) Known or suspected contaminants in soil (list general groups of contaminants): A tabular summary of soil analytical data in comparison to the February 2018 North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) is included as Table 1. Soil sample locations are shown in Figure 2. A brief summary of the results is provided below. VOCs have not been detected in soil samples at concentrations above residential or industrial/commercial PSRGs. Several polycyclic aromatic hydrocarbons (PAHs) were detected at concentrations above the residential and/or industrial/commercial PSRGs in soil sample SB-4 (1.5-2.5 ft), which was collected from the approximate location of former on-Site gasoline underground storage tanks (USTs). 7 EMP Version 2, June 2018 Hexavalent chromium was detected above residential PSRGs in samples SB-1 (0.5-1.0 ft) and SB-2 (0.5-1.5 ft), which were collected in a former dye room in the southern portion of the site. Hexavalent chromium was also detected in sample SB-3 (0.5-1.5 ft), which was collected within the footprint of a former coal storage shed in the central portion of the site. Arsenic was also detected in sample SB-3 (0.5-1.5 ft) above the industrial/commercial PSRG and the published average background level for North Carolina soils. However, the arsenic detection in SB-3 (0.5- 1.5 ft) is within the range of published background levels for North Carolina soils. The detected hexavalent chromium and arsenic concentrations appear to be naturally occurring. Additional metals, including barium, cobalt, copper, mercury, nickel, and selenium, were detected at concentrations generally consistent with published average background levels for North Carolina soils. 2) Depth of known or suspected contaminants (feet): 0.5-2.5 feet. 3) Area of soil disturbed by redevelopment (square feet): The area of potential soil disturbance is estimated to be approximately 0.5 acres (21,780 sq ft) of the 1.2-acre site. The area of potential disturbance will consist of the existing parking areas (future parking lot and patio) and landscaped areas. The remainder of the site will remain covered by the existing buildings and the light rail and adjacent walkways. 4) Depths of soil to be excavated (feet): Shallow soil disturbance (i.e., less than 1 ft) on the Brownfields property is currently planned as part of re-paving of the parking lot. Excavation for the installation of new utilities may include trenching to depths of up to 5 ft bgs. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Based on conservative estimates of potential disturbance of up to 2 ft across an approximately 0.5-acre area, approximately 1,600 cubic yards of soil may be disturbed. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Excavation of impacted soil is not anticipated. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Export of impacted soil is not anticipated. 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). 8 EMP Version 2, June 2018 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).

Please provide a description of the measure: 4) Please describe the following action(s) to be taken during and following excavation and management of site soils: Management of fugitive dust from site ☒ Yes, describe the method will include: Significant areas of contaminated soil are not expected to be encountered or disturbed during site redevelopment activities based upon soil sampling data. The grading contractor will consider conditions such as wind speed, wind direction, and moisture content of soil during soil grading and stockpiling activities to minimize dust generation. In the unlikely event that contaminated soil is encountered during site redevelopment that requires excavation, particular attention will be paid by contractors to implement dust control measures as needed based on site and atmospheric conditions (i.e. by controlled water application, hydro-seeding, and/or mulch, stone, or plastic cover). Potentially impacted soil Click or tap here to enter text. 10 EMP Version 2, June 2018 will be managed as described below. ☐ No, explain rationale: Click or tap here to enter text. Field Screening of site soil ☒ Yes, 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. chemicals, tanks, drums, etc.). Should the above be noted during site work, the contractor will contact the project environmental engineer to observe the suspect condition. If the project environmental engineer 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 two business days to advise of the condition. ☐ No, explain rationale: Click or tap here to enter text. Soil Sample Collection ☐ Yes, describe the sampling method (e.g., in-situ grab, composite, stockpile, etc.): Click or tap here to enter text. ☒ No, explain rationale: Collection of additional soil samples is not anticipated based on the results of previous site assessment activities. If significant soil impact is encountered during grading and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading and/or construction of the utility to continue and/or only as far as needed to allow alternate corrective measures as described below. Suspect significantly impacted soil excavated during grading and/or utility line installation or removal may be stockpiled and covered in a secure area to allow construction to progress. Suspect impacted soil will be underlain by and covered with minimum 10-mil plastic sheeting. At least one representative sample of the soil will be collected for analysis of total VOCs, SVOCs, and RCRA metals. If the results of analysis of the sample indicate that the soil could potentially exceed toxicity characteristic hazardous waste criteria, then the soil will also be analyzed by TCLP for those compounds that could exceed the toxicity characteristic hazardous waste criteria. Impacted soil will be handled in the manner described below based upon the laboratory analyses: i. If no organic compounds are detected in a sample (other than which are attributable to sampling or laboratory artifacts) and metals are below unrestricted use PSRGs or are consistent with site-specific background levels, then the soil will be deemed suitable for use as on-site fill or as off-site fill. The proposed location(s) for off-site 11 EMP Version 2, June 2018 placement of soil (other than a 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 unrestricted use PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with site-specific background levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil may be used on-site as fill without conditions. iii. If detectable levels of compounds are found which exceed the unrestricted use PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with background levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil, with DEQ’s written approval, may be used on-site as fill below an impervious surface, at least 2 ft of compacted clean soil, or a geotechnical fabric. If the impacted soil with concentrations above unrestricted use 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 clean soil, an impervious surface, or covered with a geotechnical fabric. iv. Impacted soil may be transported to a permitted facility such as a landfill provided that the soil is accepted at the disposal facility. If soil is transported to a permitted facility, the permitted facility’s written approval to dispose of soil from the site will be included with the final EMP report. In the unlikely event that the sample data indicates concentrations above TCLP hazardous waste criteria, then the soil must be transported off-site to a permitted disposal facility that can accept or treat hazardous waste. *Please note that should the PD elect to transport export soil to a permitted facility or to a DEQ Brownfields pre-approved receiving facility, soil will be direct loaded onto trucks for transport off-site. If soil samples are collected for analysis, please check the applicable chemical analytes: ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Method 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): 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) (i.e. Hexavalent Chromium, Herbicides, etc.): Specify Analytical Method Number(s): Click or tap here to enter text. 12 EMP Version 2, June 2018 ☒ Check to confirm that stockpiling of known or suspected impacted soils will be conducted in accordance with Figure 1 of this EMP.

According to the Brownfields IR 15, “Documenting imported soil (by sampling, analysis, and reporting in accordance with review and written approval in advance by the Brownfields Program), will safeguard the liability protections provided by the brownfields agreement and is in the best interest of the prospective developer/property owner.” Requirements for importing fill: 1) Will fill soil be imported to the site?................................................ ☐ Yes ☒ No ☐ Unknown 2) If yes, what is the estimated volume of fill soil to be imported? Structural fill is not anticipated to be imported to the site. However, limited amounts of organic rich topsoil may be imported from a commercial landscape material vendor for use in proposed landscaped areas. 3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range of depths, please list the range.) 0 to 2 feet 4) Provide the source of fill, including: location, site history, nearby environmental concerns, etc. Attach aerial photos, maps, historic Sanborn maps and a borrow source site history: As noted above, importing fill soil is not anticipated at this time. Should import soil be needed during redevelopment of the Brownfields property, DEQ will be notified and the procedures outlined below will be implemented. 5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill soil to demonstrate that it meets acceptable standards applicable to the site and can be approved for use at the Brownfields property. The PD plans to import limited amounts of organic rich topsoil from a commercial landscape material vendor for use in proposed landscaped areas. The PD does not plan to collect samples of landscaping materials prior to placement at the Site. DEQ Brownfields will be notified of the volume of landscaping material needed and the proposed source of the material prior to placement in proposed landscaping areas. Import fill for grading and or construction purposes is not anticipated at this time. However, see No. 7 below for details outlining the proposed plan to demonstrate import soil meets acceptable standards applicable to the Site should import soil be needed during redevelopment. 6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 14 EMP Version 2, June 2018 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): 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) (i.e. Hexavalent Chromium, Herbicides, etc.): Click or tap here to enter text. 7) The scope of work for import fill sampling may be provided below or in a Work Plan submitted separately for DEQ review and approval. Attach specific location maps for in-situ borrow sites. If using a quarry, provide information on the type of material to be brought onto the Brownfields Property. The PD will follow the procedures outlined below to demonstrate import soil meets acceptable standards applicable to the Site: - - If the PD plans to import fill material from Vulcan Materials Company quarry located near Pineville, NC or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC, no samples of the import material will be collected as adequate analytical data is available in the DEQ Brownfields database to demonstrate material from these facilities is suitable for use as structural fill at a Brownfields property. - If fill soil is obtained from an off-Site property that is not a known permitted quarry, a sampling plan will be developed and submitted for DEQ review. DEQ approval of the sampling plan and analytical results will be obtained prior to transporting import soil to the Site. The specific sampling rate will be outlined in the aforementioned sampling plan. However, if the proposed borrow source has not been previously developed (i.e., virgin land), soil samples will be collected for laboratory analyses indicated above at a general rate of one per 1,000 cubic yards. If the borrow source property has been previously developed, soil samples will be collected for laboratory analyses indicated above at a general rate of approximately one per 500 cubic yards. Fill soil will be considered suitable for use at the Site if it does not contain compound concentrations above DEQ IHSB unrestricted use PSRGs and metals concentrations are generally consistent with previously identified background concentrations at other Brownfields sites in the South End district of Charlotte. Part 1.C. EXPORTED SOIL NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE BROWNFIELDS PROGRAM. FAILURE TO OBTAIN APPROVAL MAY VIOLATE A BROWNFIELDS AGREEMENT CAUSING A REOPENER OR JEOPARDIZING ELIGIBILITY IN THE PROGRAM, ENDANGERING LIABILITY PROTECTIONS AND MAKING SAID ACTION POSSIBLY SUBJECT TO ENFORCEMENT. JUSTIFICATIONS PROVIDED BELOW MUST BE APPROVED BY THE PROGRAM IN 15 EMP Version 2, June 2018 WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES. Please refer to Brownfields IR 15 for additional details. 1) If export from a Brownfields Property is anticipated, please provide details regarding the proposed export actions. Volume of exported soil, depths, location from which soil will be excavated on site, related sampling results, etc. Provide a site map with locations of export and sampling results included. Export soil is not anticipated at this time. If exporting soil is ultimately necessary, a sampling plan will be developed and submitted to DEQ Brownfields for review and approval once the volume of soil for export is known. Generally, soil samples will be collected from export soil at a rate of 1 sample per every 400-500 cubic yards of export. DEQ approval of the sampling plan and analytical results will be obtained prior to transporting export soil from the site. Based on analytical results of soil samples collected from the export soil, the soil will be transported off-site to a suitable location. The PD will notify DEQ Brownfields of the location receiving the export soil. If not a permitted facility, DEQ Brownfields approval and written approval from the receiving facility will be obtained prior to transporting the soil off- site. 2) To what type of facility will the export Brownfields soil be sent? ☒ Subtitle D/Municipal Solid Waste Landfill (analytical program to be determined by landfill) ☒ Permitted but Unlined Landfill (i.e. LCID, C&D, etc.) Analytical program to be determined by the accepting Landfill; ☒ Landfarm or other treatment facility ☒ Use as fill at another suitable Brownfields Property – determination that a site is suitable will require, at a minimum, that similar concentrations of the same or similar contaminants already exist at both sites, use of impacted soil will not increase the potential for risk to human health and the environment at the receiving Brownfields property, and that a record of the acceptance of such soil from the property owner of the receiving site is provided to Brownfields. Please provide additional details below. ☒ Use as Beneficial Fill off-site at a non-Brownfields Property - Please provide documentation of approval from the property owner for receipt of fill material. This will also require approval by the DEQ Solid Waste Section. Additional information is provided in IR 15. Please provide additional details below. 3) Additional Details: (if transfer of soil to another property is requested above, please provide details related to the proposed plans). The environmental engineer will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ Solid Waste approval prior to exporting soil to a non-Brownfields property. 16 EMP Version 2, June 2018 Part 1.D. MANAGEMENT OF UTILITY TRENCHES ☐ Install liner between native impacted soils and base of utility trench before filling with clean fill (Preferred) ☒ Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a hazardous waste), i.e., impacted soils are placed back at approximately the depths they were removed from such that impacted soil is not placed at a greater depth than the original depth from which it was excavated. ☐ Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport, and/or degradation of conduit materials due to direct impact with contaminants? ☐ If yes, provide specifications on barrier materials: Click or tap here to enter text. ☒ If no, include rationale here: No VOCs have been detected in vapor samples collected at the site at concentrations above the DEQ Division of Waste Management (DWM) Vapor Intrusion Screening Levels (VISLs). Sub-slab vapor data is summarized in Table 2. Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in the event contaminated soil and/or vapors are encountered in utility trenches during redevelopment activities, the trench will be evacuated and appropriate safety screening of the vapors will be performed to protect workers. If results indicate further action is warranted in response to vapors to protect workers, appropriate engineering controls (such as use of industrial fans) will be implemented. The contractor and workers will observe soil for potential impacts during utility installation activities. Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or filled or previously disposed materials of concerns (i.e. chemicals, tanks, drums, etc.). Should the above be noted during utility work, the contractor will contact the project environmental engineer to observe the suspect condition and screen the soil using a photo-ionization detector (PID) or other similar vapor field screening instrument. If the project environmental engineer confirms that the material may be impacted, then the procedures outlined Managing On-Site Soil above (Part 1.A.) will be implemented. In addition, the environmental engineer will contact the DEQ Brownfields project manager within two business days to advise that person of the condition PART 2.

Therefore, a vapor mitigation plan is not warranted for the proposed redevelopment of the site. CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials 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: ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver) EPA Method 6020 and EPA Method 7471 further action is warranted, appropriate engineering controls (such as use of industrial fans) will be implemented. 22 EMP Version 2, June 2018 ☐ 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) (i.e. Hexavalent Chromium, Herbicides, etc.) Please note, if field observations indicate the need for additional analyses, they should be conducted, even if not listed here. 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. During construction activities, contractors may encounter unknown sub-surface environmental conditions (i.e. tanks, drums, or waste materials) that if encountered, will require proper management. Prior to beginning site work, H&H will attend a pre-construction kick-off meeting with the PD and the redevelopment contractors to discuss the DEQ approved EMP and various scenarios when it would be appropriate and necessary to notify H&H of the discovery of unknown subsurface features or potentially impacted media at the site. In the event that such conditions are encountered during site development activities, the environmental actions noted below will be used to direct environmental actions to be taken during these activities and sampling data for potentially impacted soil and the disposition of impacted soil will be provided to DEQ when the data becomes available. Underground Storage Tanks: In the event a UST or impacts associated with a UST release are discovered at the site during redevelopment activities, the UST and/or UST related impacts will be addressed through the Brownfields Program. If a UST is encountered that cannot be removed or does not require removal for geotechnical or construction purposes, it will be abandoned in-place and construction will proceed. Where appropriate, the bottom 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. Impacted soil will be managed in accordance with the Managing On-Site Soil section outlined above in the EMP. 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 23 EMP Version 2, June 2018 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 to a significant degree, the concrete will be sampled and analyzed by methods specified by the disposal facility. Buried Waste Material: If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to stop work in that location and notify the environmental consultant. The environmental consultant will review the materials and collect samples if warranted. In this event, confirmation sampling will be conducted at representative locations in the base and the sidewalls of the excavation after the waste or significantly impacted soil is removed. The confirmation samples will be analyzed for VOCs, SVOCs, and RCRA metals. Areas of suspected contaminated soil that remain at the site after excavation is complete above the DEQ unrestricted use PSRGs will be managed pursuant to this plan. Re-Use of Impacted Soils On-Site: Please refer to description outlined in the Managing On-Site Soil section (Part 1.A.) of the EMP above. If unknown, impacted soil is identified on-site, management on-site can be considered after the project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields Project Manager approval prior to final placement on-site.
