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 specific compounds): Historical use of the Brownfields property included truck and bus repairs (1920s-1950s), electrical switchboard and switch manufacturing (1920s-mid 1960s), and janitorial chemical manufacturing uses (mid-1970s to current). Laboratory analytical results of soil samples collected during March 2018 Brownfields assessment activities, identified arsenic (up to 17 mg/kg) and lead (up to 9,300 mg/kg) at concentrations exceeding the North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Residential and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs). Benzo(a)anthracene (up to 1.3 mg/kg), benzo(a)pyrene (up to 1.3 mg/kg), benzo(b)fluoranthene (up to 1.8 mg/kg), dibenz(a,h)anthracene (up to 0.30 mg/kg), and hexavalent chromium (up to 3.2 mg/kg) were detected at concentrations exceeding the Residential PSRGs. No other compounds have been identified at concentrations exceeding Residential or Industrial/Commercial PSRGs in Site soil. Soil sample laboratory analytical results are summarized in Table 1 and depicted on Figure 4. 2) Depth of known or suspected contaminants (feet): Compounds at concentrations above the Industrial/Commercial PSRGs were identified in shallow soil (0-1 ft bgs) in the sample collected from soil boring SB-6 advanced in the vicinity of the former electrical switchboard manufacturing area (currently known as the "light well area"). Additionally, compounds detected at concentrations exceeding the Residential PSRGs were identified in the SB-8 soil sample at a depth of 4.5 -5.5 ft bgs collected adjacent to the former above -ground storage tank (AST) secondary containment system. 3) Area of soil disturbed by redevelopment (square feet): Approximately 12,000 sq ft will be disturbed in portions of the Brownfields property planned for parking, installation of subgrade utilities, installation of the stormwater conveyance system, installation/repair footings, and repair of building concrete slab floors. Grading activities will be limited to leveling for new paved parking areas. Site grading activities will be conducted in accordance with a grading plan utilizing grading equipment (i.e. backhoes, front end loaders, bull dozers etc.) and the Site development contractor will implement best management practices (i.e. implementation of silt fencing, berming, and covering stockpiled soil with plastic) to manage soil during Site redevelopment activities to prevent redistribution of soils onto adjacent properties. The proposed Grading Plan is included in Appendix D. 4) Depths of soil to be excavated (feet): Soil excavation for installation stormwater conveyance piping, subgrade utilities, and the concrete footings may extend up to approximately 5 ft bgs. 4 EMP Form ver.1, October 23, 2014 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Up to approximately 1,600 cubic yards of soil are planned to be disturbed and re -used on -Site during grading activities. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Up to approximately 100 cubic yards of potentially impacted soil may be excavated or disturbed during redevelopment of the Brownfields property. If soil is disturbed during grading/Site work activities in the vicinity of soil sample S13-6 (light well area), or if unexpected potentially impacted soil is encountered during grading activities on the Brownfields property, soil will be segregated and stockpiled on and covered with a minimum of 10-mil plastic to allow for construction activities to continue. An environmental professional will collect a composite soil sample from the stockpile for laboratory analysis (as described in the Managing Onsite Soil section below) to determine the appropriate final disposition of the potentially impacted material. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: None anticipated IMPORTED FILL SOIL 1) Will fill soil be imported to the site? ❑ Yes ❑ No ❑x Unknown 2) If yes, what is the estimated volume of fill soil to be imported? Import soil for use as beneficial fill is not anticipated at this time. Should import soil be needed during redevelopment of the Brownfields property, the PD will contact DEQ Brownfields and the procedures outlined in item #4 below will be implemented. 3) If yes, what is the depth of fill soil to be used at the property? Not applicable If a range of depths, please list the range. 4) PRIOR TO ITS PLACEMENTAT THE BROWNFIELDS PROPERTY, provide plan to analyze fill soil to demonstrate that it meets acceptable standards and can be considered clean for use at the Brownfields property (Check all that apply): ® 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 (speciated), mercury, lead, selenium and silver) ❑ Metals —Hazardous Substance List -14 (antimony, arsenic, beryllium, cadmium, chromium (speciated according to IHSB protocol), copper, lead, manganese, mercury, nickel, selenium, silver, thallium, and zinc) ❑ Metals — EPA Priority Pollutant List — 13 (arsenic, beryllium, cadmium, chromium (speciated according to IHSB protocol), copper, mercury, nickel, lead, antimony, selenium, silver, thallium, and zinc) ❑ Other Constituents & Analytical Method: rlirk harp to antpr tax ❑ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE): The PD does not plan to collect samples of landscaping materials obtained from a commercial vendor 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. For import structural fill needed for future redevelopment of the Site, the PD will follow the procedures outlined below. EMP Form ver.1, October 23, 2014 If the PD plans to import fill material from the 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. For import material from unknown borrow sources, prior to bringing fill soil to the Site, historical information about the fill Site and a proposed sampling design will be provided to DEQ for review and approval based upon the estimated quantity of import fill to be obtained from the fill site. The soil sample(s) will be analyzed for VOCs, SVOCs, and RCRA metals plus hexavalent chromium. Fill soil will be considered suitable for use at the Site if it does not contain compound concentrations above NCDEQ PSRGs for Industrial/Commercial Use or typical metals concentrations which are consistent with background levels identified at the Site. Fill soil may also be obtained from another Brownfields property with DEQ Brownfields prior written approval. MANAGING ONSITE SOIL 1) If soil in known or suspected areas of contamination 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). 2) HAZARDOUS WASTE DETERMINATION — 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). Click here to enter text. If yes, do the soils exceed the "Contained -Out" levels in Attachment 1 of the North Carolina Contained -In Policy? ❑ Yes ❑ No NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS THE CONTAINED -OUT LEVELS IN ATTACHMENT 1 TO THE NORTH CAROLINA CONTAINED -IN POLICY THE SOIL MAY NOT BE RE -USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DENR HAZARDOUS WASTE SECTION RULES AND REGULATIONS. 3) HAZARDOUS WASTE DETERMINATION — Does the soil contain a CHARACTERISTIC WASTE?: ® Yes ❑ No If yes, mark reason(s) why below (and include pertinent analytical results). ❑ Ignitability ❑ Corrosivity ❑ Reactivity ❑ Toxicity ® TCLP results — Elevated lead concentrations (up to 9,300 mg/kg) were detected in soil sample SB-6 and the S13-6 duplicate soil sample DUP-1 collected at a depth of 0-1 ft bgs in the light 6 EMP Form ver.1, October 23, 2014 well area. Based on laboratory analytical results of the SB-6 and DUP-1 soil samples, the samples were submitted for laboratory analysis for lead by Toxicity Characteristic Leaching Procedure (TCLP). TCLP laboratory analytical results indicate that lead was detected at concentrations (up to 29 mg/L) exceeding the Regulatory Level for lead of 5 mg/L in the soil samples collected from the light well area. Laboratory analytical results of the TCLP analysis are included in Appendix E. ❑ Rule of 20 results (20 times total analytical results for an individual hazardous constituent on TCLP list cannot, by test method, exceed regulatory TCLP standard) If no, explain rationale: NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE SOIL MAY NOT BE RE -USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DENR HAZARDOUS WASTE SECTION RULES AND REGULATIONS. 4) Screening criteria by which soil disposition decisions will be made (e.g., left in place, capped in place with low permeability barrier, removed to onsite location and capped, removed offsite): ❑ Preliminary Health -Based Residential SRGs ® Preliminary Health -Based Industrial/Commercial SRGs 2/1/2018 ❑ Site -specific risk -based cleanup level, or acceptable concentrations determined via calculated cumulative risk. Enter details of methods used for determination/explanation: 5) Check the following action(s) to be taken during excavation and management of said soils: ® Manage fugitive dust from site: ® Yes ❑ No If yes, describe method; If no, explain rationale: Limited areas of potentially impacted soil will be encountered or disturbed during future Site redevelopment activities based upon previous soil sampling analytical data. The grading contractor will take into account conditions such as wind speed, wind direction, and moisture content of soil during soil grading and stockpiling activities to minimize dust generation. In the 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). Impacted soil will be managed as described below. ® Field Screening: ® Yes ❑ No If yes, describe method; If no, explain rationale: During soil disturbance at the Site, the workers or contractors will observe soils for evidence of potential significantly impacted soil. 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 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. 7 EMP Form ver.1, October 23, 2014 ® Soil Sample Collection: ® Yes ❑ No If yes, describe method (e.g., in -situ grab, composite, stockpile, etc.); If no, explain rationale: If significant soil impact is encountered during grading, installation of concrete footings and slabs, and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading and/or construction to continue and/or only as far as needed to allow alternate corrective measures described below. Soils disturbed from the immediate vicinity of soil boring SB-6, as well as suspect significantly impacted soil excavated during redevelopment activities will 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 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 the 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 the DEQ Residential PSRGs or are consistent with published and 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 acknowledgement 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 Industrial/Commercial 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 restriction. iii. If detectable levels of compounds are found which exceed the DEQ 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, 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 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. ® Stockpile impacted soil in accordance with NCDENR IHSB protocol in the current version of the "Guidelines for Assessment and Cleanup", and providing erosion control, prohibiting contact between surface water/precipitation and contaminated soil, and preventing contaminated runoff. Explain any variances: 8 EMP Form ver.1, October 23, 2014 ® Analyze potentially impacted soil for the following 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 (speciated), mercury, lead, selenium and silver) ❑ Metals —Hazardous Substance List -14 (antimony, arsenic, beryllium, cadmium, chromium (speciated according to IHSB protocol), copper, lead, manganese, mercury, nickel, selenium, silver, thallium, and zinc) ❑ Metals — EPA Priority Pollutant List — 13 (arsenic, beryllium, cadmium, chromium (speciated according to IHSB protocol), copper, mercury, nickel, lead, antimony, selenium, silver, thallium, and zinc) ❑ Other Constituent(s) & Analytical Method(s): If suspected contaminated soil is identified during Site redevelopment activities, soil will be sampled and analyzed for VOCs, SVOCs, and RCRA metals plus hexavalent chromium. VOC and SVOC concentrations will be compared to Industrial/Commercial Use PSRGs. Metal concentrations will be compared to Industrial/Commercial Use PSRGs, Site -specific background levels. ® Proposed Measures to Obtain Pre -Approval for Reuse of Impacted Soil within the Brownfields Property Boundary ® Provide documentation of analytical report(s) to Brownfields Project Manager ® Provide documentation of final location, thickness and depth of relocated soil on site map to Brownfields Project Manager once known ® Use geotextile to mark depth of fill material (provide description of material) ® Manage soil under impervious cap ® or clean fill Describe cap orfill: If contaminated soil is encountered, it will be placed under impervious materials or at least 2 ft of clean fill. Potential impervious caps include future building foundations and paved areas. See attached development plan in Appendix B.

Based on observations made by the environmental professional, a plan will be prepared for final grade sampling and submitted to DEQ Brownfields for review and approval. OFFSITE TRANSPORT & DISPOSITION OF EXCAVATED SOIL NOTE: Unless soil will be transported offsite for disposal in a permitted facility under applicable regulations, no contaminated or potentially contaminated soil may leave the site without approval from the brownfields program. Failure to obtain approval may violate a brownfields agreement, endangering liability protections and making said action subject to enforcement. Justifications provided below must be approved by the Program in writing prior to completing transport activities. ® Transport and dispose of impacted soil offsite (documentation of final disposition must be sent to Brownfields Project Manager) ® Landfill - analytical program determined by landfill ® Landfarm or other treatment facility Click here to enter text. ❑ Use as Beneficial Fill Offsite - provide justification: slick hero t- ontor to- ® Use as Beneficial Fill at another Suitable Brownfields Site - (Note: a determination that a site is a "Suitable Brownfields" site will require, at a minimum, that similar concentrations of the same or similar contaminants already exist at both sites, use of impacted soil as beneficial soil will not increase the potential for risk to human health and the environment at that site, and that notarized documentation of the acceptance of such soil from the property owner of the receiving site is provided to Brownfields. Provide justification: As previously mentioned, cut/fill at the site is expected to balance. However, in the unlikely event that soil needs to be exported off -site, a request will be submitted to DEQ requesting approval prior to movement of soil off -site, unless the soil is taken to a permitted facility. 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?

GROUNDWATER — Please fill out the information below and attach figure showing distribution of groundwater contaminants at site What is the depth to groundwater at the Brownfields Property? During groundwater assessment activities conducted at the Site in March 2018, the potentiometric groundwater surface was measured at depths ranging from approximately 13.3 ft bgs (TMW-3) in the northeastern portion of the Site to approximately 16.5 ft bgs (TMW-1) in the northwestern portion of the Site. Is groundwater known to be contaminated by ®onsite ® offsite ❑ both ❑ or unknown sources? Describe source(s): Laboratory analytical results of groundwater samples collected during March 2018 Brownfields assessment activities identified benzene (up to 7.9 µg/L), naphthalene (up to 6.6 µg/L), carbon tetrachloride (up to 4.8 J µg/L), and 1-methylnaphthalene (up to 2.6 J µg/L) at concentrations exceeding the DEQ groundwater screening criteria established under 15A NCAC 02L.0202 in upgradient temporary groundwater monitoring wells TMW-4 and/or TMW-5. Carbon tetrachloride in the TMW-4 groundwater sample also slightly exceeds the DEQ Division of Waste Management (DWM) February 2018 Residential Vapor Intrusion Groundwater Screening Level (GWSL). Vinyl chloride (0.85 J µg/L) and trichloroethylene(TCE) (11 µg/L) were detected at concentrations exceeding the 2L Standards in the TMW-2 groundwater sample collected downgradient of the former bus repair area and Wepak Corporation operations. The TCE concentration also exceeds the DEQ DWM Non -Residential GWSL. However, DEQ Risk Calculator (February 2018) results indicate that cumulative Carcinogenic Risk (2.4 X 10-6) and the cumulative Hazard Index (0.51) for compounds detected in the TMW-2 groundwater sample are within the acceptable risk range for a Non -Residential use scenario. What is the direction of groundwater flow at the Brownfields Property? Groundwater beneath the Site is expected to mimic surface topography and flow approximately from south-southwest toward the north-northeast. Will groundwater likely be encountered during planned redevelopment activities? ❑ Yes ® No If yes, describe these activities: It is not anticipated that groundwater will be encountered during construction activities conducted in the area of planned redevelopment. Should groundwater reach the surface during redevelopment of the Brownfields property, the PD or the PD's contractor will contact the project environmental engineer. The environmental engineer will update the DEQ Brownfields project manager within two business days. 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, or sampling procedures): Although not anticipated at this time, appropriate worker safety measures will be undertaken if groundwater gathers in an open excavation within an area determined to be impacted during construction activities. The accumulated water will be allowed to evaporate, tested and disposed off -site (if impacted), or tested and discharged to the storm sewer (if not impacted above DEQ surface water standards) in accordance with applicable municipal and State regulations for erosion control and construction stormwater control. 11 EMP Form ver.1, October 23, 2014 PART 3.

Background Cd and Ag concentrations were taken from Southeastern and Conterminous US soils. Soil concentrations are reported in milligrams per kilogram (mg/kg). Compound concentrations are reported to the laboratory method detection limits. Bold values exceed Residential Health -based PSRGs and for metals exceed Site -specific ranges of concentration and mean regional background concentrations Underlined values exceed Industrial/Commercial PSRG Laboratory analytical methods are shown in parentheses. VOCs = volatile organic compounds; SVOCs = semi -volatile organic compounds; PCBs = polychlorinated biphenyls; UST = underground storage tank; AST = aboveground storage tank; ft bgs= feet below ground surface NA = Not Analyzed; NS = Not Specified; -- = Not Applicable; BRL = below laboratory reporting limits J = compound was detected above the laboratory method detection limit but below the laboratory reporting limit resulting in an estimated concentration. B = Analyte is found in the associated blank as well as in the sample. R-05=Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any reported value for this compound. MS-11 = Matrix spike recovery outside of control limits. Possibility of sample matrix effects that lead to a high bias for reported result or non -homogeneous sample aliquots cannot be eliminated. MS-19 = Sample to spike ratio is greater than or equal to 4:1. Spiked amount is not representative of the native amount in the sample. Appropriate or meaningful recoveries cannot be calculated. R-02 = Duplicate relative percent difference (RPD) is outside of control limits. Outlier can be attributed to sample non -homogeneity encountered during sample prep. * Heterogeneous lithology in SB-6 (0-1) likely caused differences in concentrations of SVOCs, hexavalent chromium, and mercury in duplicate sample DUP-01 when compared to the SB-6 parent sample. SB-6 and DUP-1 soil samples were homogenized by the laboratory and re -analyzed for RCRA metals by EPA method 6020 A-B. Soil samples from SB-6 and DUP-1 were outside of the hold times for re -analysis of SVOCs and hexavalent chromium and were therefore not re -submitted.

Acid �.= Base Appendix F Contingency Plan Contingency Plan Wepak Property Charlotte, North Carolina Brownfields Project No. 21048-17-060 H&H Job No. MGN.002 This Contingency Plan is being provided as required by Part 9 of the NC DEQ template Environmental Management Plan (EMP) for future redevelopment at the Wepak Property Brownfields property located in Charlotte, Mecklenburg County, North Carolina (Site). Current redevelopment plans for the Site include renovation of the existing Site buildings for commercial uses and Site work activities such as concrete footing repair/replacement, utility installations, and shallow grading for paved parking areas. Contingency Actions 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. 1. 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 the RCRA metals plus hexavalent chromium. Areas of suspected contaminated soil that remain at the Site after excavation is complete above the DEQ IHSB Industrial/Commercial Use PSRGs will be managed pursuant to this plan and incorporated into the Brownfields plat. 2. If determined to be warranted, confirmation samples will also be used to determine the appropriate corrective measure for soil beyond the excavation limits required for grading and/or utility line installation or removal. Such corrective measures are specified in the items below. 3. 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 suitable permitted facility or the waste will be managed in accordance with Paragraph 3 of this section 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. 4. If buried piping is encountered and must be removed to allow installation to proceed, the contractor will inspect the pipe for fluids, collect the fluids where appropriate, and look for signs of a release using field methods. The collected fluids will be sampled for VOCs, SVOCs, and RCRA metals to determine appropriate disposition of the fluid. 5. In the event that soil within an excavation cannot be dried adequately for construction purposes using the methods described above, the soil may be amended with clean soil, aggregate, drying agents, and/or stabilizing agents to achieve the desired geotechnical qualities or placed within the void space beneath impervious surface cover. Amendment may be conducted inside or outside the excavation and the material replaced into the excavation. If an amendment is used, the type of amendment will be provided to DEQ for approval prior to its use. DEQ will be notified prior to movement of the soil to other areas at the Site if results of laboratory analysis for soil samples collected from the excavation indicate that compound concentrations are detected above Industrial/Commercial Use PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with Site -specific background levels for metals). 6. In the event that impacts associated with an UST release are found to be present on the subject Site, they will be addressed through the Brownfields Program.
