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.

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 former gas station with auto service operations was developed in the northeastern portion of the Site in 1957 and operated until the 1970s. The gas station operated six underground storage tanks (USTs) that were removed in the late 1990s. Four former gasoline USTs were present within a single basin located in the northeastern portion of the Site. Additionally, one former heating oil UST and one former waste oil UST were present in two separate basins in the northeastern portion of the Site. Multiple soil assessment events have been conducted at the Brownfields Property. A brief summary of the soil assessment results is provided below. Total Petroleum Hydrocarbons (TPH) During UST closure activities, gasoline-range TPH (TPH-GRO) was reported in soil samples collected from the gasoline tank basin at concentrations up to 1,400 mg/kg. Additionally, diesel- range TPH (TPH-DRO) was reported in soil samples collected from the former heating oil tank basin at concentrations up to 1,000 mg/kg. Volatile Organic Compounds (VOCs) Laboratory analytical results have indicated the presence of naphthalene (up to 63 mg/kg) at concentrations above the Industrial/Commercial PSRG in the vicinity of the former gasoline tank basin. Additionally, during a 1998 assessment, the non-petroleum compound trichloroethylene 7 EMP Version 2, June 2018 (TCE; up to 6.9 mg/kg) was reported in one boring located in the vicinity of the former gasoline tank basin at concentrations above the Industrial/Commercial PSRG. Please note that subsequent assessments did not confirm the presence of TCE in Site soil. Multiple low-level petroleum-related VOCs have been detected in the vicinity of the former tank basins, but at concentrations below Industrial/Commercial PSRGs. Semi-Volatile Organic Compounds (SVOCs) Laboratory analytical results have indicated the presence of low-level SVOCs at the Site, but at concentrations below the Industrial/Commercial PSRGs. Metals Laboratory analytical results have identified chromium (total; up to 69 mg/kg) at concentrations exceeding the Industrial/Commercial PSRG in the vicinity of the former waste oil tank product line. Please note that speciated chromium analysis was not performed during the waste oil tank assessment activities. Low-level hexavalent chromium has been detected in shallow soil across the Site at estimated concentrations above the Residential PSRGs, but below the Industrial/Commercial PSRGs. H&H did not identify obvious former activities at the Site associated with hexavalent chromium use. Elevated arsenic concentrations have been detected across the Brownfields Property at concentrations above the Industrial/Commercial PSRG, but within published background ranges for North Carolina soils. 2)Depth of known or suspected contaminants (feet): Residual petroleum impacts at the Site have been reported at depths of up to 15 ft below ground surface (bgs) in the vicinity of the former gasoline UST basin. TCE was reported during the 1998 assessment at depths of up to 20 ft bgs in the vicinity of the former gasoline UST basin (depth of sample likely influenced by groundwater). Elevated chromium (total) concentrations were reported from a depth of up to 4 ft bgs from beneath the former waste oil tank product line. Elevated arsenic concentrations have been detected across the Site at depths ranging from 0.5 ft to 2 ft bgs. 3)Area of soil disturbed by redevelopment (square feet): An area of approximately 122,840 square feet (the entire Brownfields Property) will be graded to level the property prior to importing fill and to implement positive drainage flow across the Site. 4)Depths of soil to be excavated (feet): No soil will be excavated during Site grading activities for the purpose of changing the grade because this is a soil import-site. 5)Estimated volume of soil (cubic yards) to be excavated (attach grading plan): No soil is anticipated to be excavated as this is a soil-import site. A grading plan is included in Appendix A. 6)Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Not Applicable 8 EMP Version 2, June 2018 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Not Applicable 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 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).

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 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 significantly impacted soil. Evidence of potential significantly 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 environmental engineer will contact the DEQ Brownfields project manager within two business days to advise that person 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 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 described below. Suspect significantly impacted soil excavated during grading and/or utility line installation or removal may be stockpiled and 11 EMP Version 2, June 2018 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 plus hexavalent chromium. 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 Industrial/Commercial 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 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 the DEQ IHSB 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 DEQ IHSB 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 (i.e. parking lot or building foundation), or at least 2 ft of compacted 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, covered with a geotextile fabric so that its location can be identified if encountered in the future, and its location will be provided to DEQ in an updated survey plat. 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 redevelopment summary 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. 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 12 EMP Version 2, June 2018 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Methods 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): Hexavalent Chromium (EPA Method 7199) ☒ 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: ☐ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or permanent hardscape).

Please provide a scope of work for final grade sampling, including a diagram of soil sampling locations, number of samples to be collected, and brief sampling methodology. 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, a work plan for final grade sampling may be submitted under separate cover. Click or tap here to enter text. Click or tap here to enter text. 13 EMP Version 2, June 2018 ☒ If final grade sampling was NOT selected please explain rationale: No final grade sampling is necessary because import soil will be tested prior to import to the Brownfields Property; Site soil has already been assessed; and most of the Site will be covered with clean fill, pavement, and/or buildings. Part 1.B. IMPORTED FILL SOIL NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL FROM THE BROWNFIELDS PROGRAM. 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? Approximately 10,000 cubic yards 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.) Fill soil will be used to raise the grade across the Brownfields Property to heights between two ft and six ft above current grade. 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: The source of fill has not been determined at this time. However, when a proposed source of fill has been identified, the procedures outlined below will be followed. 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. To demonstrate that imported soil is suitable for use at commercial property, the fill soil will be sampled and approved by DEQ Brownfields prior to being brought to the Site. A sampling plan will be developed and submitted for DEQ Brownfields review under separate cover. DEQ approval of the sampling plan and analytical results is required prior to bringing soil on Site. Soil will be considered suitable for use at the Site if it does not contain compound concentrations above Industrial/Commercial PSRGs or Site-specific background levels for metals. 6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 14 EMP Version 2, June 2018 ☒ 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 Methods 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.): Hexavalent Chromium (EPA Method 7199) 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. A sampling plan will be developed and submitted for DEQ Brownfields review under separate cover. DEQ Brownfields approval of the sampling plan and analytical results is required prior to bringing soil on Site. 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 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. Based on review of the proposed cut/fill plan, export soil is not anticipated at this time. Should soil need to be exported from the Brownfields property during redevelopment, a sampling plan will be developed and submitted to DEQ Brownfields for review and approval once the volume of soil for export is known. 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 15 EMP Version 2, June 2018 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 professional will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ Solid Waste approval prior to exporting soil to a non-Brownfields property. 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: 16 EMP Version 2, June 2018 The potential for vapor intrusion associated with future Site buildings will be managed through a Vapor Intrusion Mitigation System (VIMS) Plan that will be submitted to DEQ for approval under separate cover prior to construction of the proposed Site buildings. 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 environmental professional to observe the suspect condition and screen the soil using a photo-ionization detector (PID) or similar vapor field screening instrument. If the environmental professional confirms that the material may be impacted, then the procedures outlined in Part 1.A. above will be implemented. In addition, the environmental professional will contact the DEQ Brownfields project manager within two business days to advise that person of the condition. PART 2. GROUNDWATER – Please fill out the information below. 1) What is the depth to groundwater at the Brownfields Property? The depth to groundwater at the Brownfields Property ranges from approximately 12 ft bgs in the southern portion of the Site to approximately 20 ft bgs in the northern portion of the Site. 2) Is groundwater known to be contaminated by ☐onsite ☐offsite ☒both or ☐unknown sources? Describe source(s): Previous groundwater assessment activities have indicated the presence of petroleum-related compounds at concentrations above the North Carolina 2L Groundwater Quality Standards (2L Standards) in the northern portion of the Site in the vicinity of the former gas station and in the southern portion of the Site associated with the south adjacent off-Site gas station. Additionally, chlorinated VOCs including tetrachloroethylene (PCE), 1,2-dichloroethane (1,2-DCA), and chloroform have been detected in groundwater at the Site at concentrations exceeding 2L Standards. The source of the chlorinated VOCs is unknown; however, the Site is located in an historically industrial corridor of Charlotte and chlorinated VOC impacts have been documented on several nearby upgradient properties. 3) What is the direction of groundwater flow at the Brownfields Property? Groundwater flow at the Site is generally towards the northwest. 4) Will groundwater likely be encountered during planned redevelopment activities? ☐Yes ☒No 17 EMP Version 2, June 2018 If yes, describe these activities: Click or tap here to enter text. Regardless of the answer; in the event that contaminated 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). Based on the anticipated depth to groundwater, groundwater is not anticipated to be encountered during proposed redevelopment activities. Although not anticipated, if groundwater suspected to be impacted (based on strong odor, unnatural color, sheen, etc.) is encountered during Site work, the contractor will contact the environmental professional to observe the suspect condition. If the environmental professional determines that the excavation likely contains impacted groundwater, then appropriate worker safety measures will be undertaken to manage groundwater that gathers in an open excavation within an area determined to be impacted during construction activities. The accumulated water will be allowed to evaporate (if feasible), tested and disposed off-Site (if impacted), or used for dust control at the Site (with Brownfields prior approval). In addition, the environmental professional will contact the DEQ Brownfields project manager within 48 hours regarding the condition. 5) 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 6) 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.

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 Methods 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 & 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. Hexavalent Chromium by EPA Method 7199 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 redevelopment 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 22 EMP Version 2, June 2018 becomes available. Underground Storage Tanks: In the event 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 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 Part 1.A. above. 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 Part 1.A. 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: If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to stop work in that location and notify the environmental professional. The environmental professional 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 the RCRA metals plus hexavalent chromium. Areas of suspected contaminated soil that remain at the Site after excavation is complete above the DEQ Industrial/Commercial PSRGs will be managed pursuant to this plan and incorporated into the Brownfields plat. Re-Use of Impacted Soils On-Site: Please refer to Part 1.A. 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. If other potential contingency plans are pertinent, please provide other details or scenarios as needed below: Click or tap here to enter text. 23 EMP Version 2, June 2018 POST-REDEVELOPMENT REPORTING ☒ Check this box to acknowledge that a Redevelopment Summary Report will be required for the project.
