HomeMy WebLinkAbout19047-Performance Fibers-EMP for FXGD - signedNORTH CAROLINA BROWNFIELDS PROGRAM ENVIRONMENTAL MANAGEMENT PLAN This form is to be used to prepare an Environmental Management Plan (EMP) for projects in the North Carolina Brownfields Program at the direction of a Brownfields project manager. 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. The EMP is valid only for the scope of work described herein and must be updated to be applicable for new phases of redevelopment or after significant changes in applicable regulatory guidance. Voluntary Metrics Tab The NC Brownfields Program updates estimated capital investment (from the Brownfields Property Application) and estimated jobs created (from the Brownfields Agreement) whenever possible. As a voluntary measure, you may opt to complete the below information for capital investment and jobs created as estimated by your final redevelopment plans for the Brownfields Property: 1.

This will be the first of several tenant build -out 5 EMP Version 2, January 2021 projects on the Brownfields Property and separate EMPs will be developed for each tenant build - out. This EMP is intended to compliment the approved 9 August 2021 EMP for installation of primary utilities onto the Site. For the Lot 1 Site, construction activities will generally include management of the documented AOC (Area) #37 construction debris fill area as described in previous assessment reports, Site grading, subsurface utility installation and foundation construction within the limits of the proposed area (Figure 1). This EMP will also include options to potentially stockpile soil and obtain fill soil on/from other portions of the Brownfields Property. Current plans indicate that there are sufficient volumes of soil available on the Brownfields Property to avoid the need to import soil from off -site sources for Lot 1 construction activities. As such, a soil import plan is not included as part of this EMP. If import of soil from an off -Site source is needed, a separate plan will be provided as an addendum to this EMP. Import of stone aggregate from off -site approve quarries is included in this EMP. 2) Check the following activities that will be conducted prior to commencing earth -moving activities at the site: ® Review of historic maps (Sanborn Maps, facility maps) ❑ Conducting geophysical surveys to evaluate the location of suspect UST, fuel lines, utility lines, etc. ® Interviews with employees/former employees/facility managers/neighbors 3) Summary of Redevelopment Plans (MANDATORY: attach detailed plans or conceptual plans, if detailed plans are not available. EMP review without such information would be premature): Provide brief summary of redevelopment plans, including demolition, removal of building slabs/pavement, grading plans and planned construction of new structures: See attached Figure 1 for the location and layout of the proposed facility for Lot 1. Figure 1 also provides the approximate location of existing features on the entire Brownfields Property (i.e. portion of the Brownfields Property outside of the Lot 1 Site) including the remaining concrete slab, existing buildings, Waste Water Treatment Plant (WWTP) and associated ponds and lagoons, and existing inert debris pile. Construction of Lot 1 will include the following: • Undercut and removal of the debris from Area #37 to the proposed Construction Debris Storage Area to the north of Lot 1 (Figure 1). Concrete, asphalt and soil with no field evidence of impacts will be stockpiled in the Construction Debris Storage Area. Based on available information and pending additional stockpile sampling, this inert material and soil mixture will be available for possible reuse on other portions of the Brownfields Property. Items such as sheet metal, fabric and potentially impacted soil or other similar material not potentially suitable for reuse on other portions of the Brownfields Property will be segregated for off -site disposal. • An estimated 95,000 cubic yards of soil will be excavated during Site grading and EMP Version 2, January 2021 undercut of unsuitable soils (U) and excavation of proposed Water Quality Devices (WQD) on Lot 1. Excess soils will be used, in part, to backfill Area #37. Remaining excess soils will be stockpiled on other portions of the Brownfields Property in the Fill Area #1 and/or Fill Area #2 areas shown on Figure 1. The WWTP (including ponds/lagoons) will remain operational during initial construction of Lot 1. As such, soils stockpiled in Fill Area #1 will not be placed in the ponds/lagoons, but will be available for future WWTP closure. Fill Area #2 will also be available for stockpiling as needed. Future EMPs for other tenant build -out lots on the Brownfields Property will be able to access these stockpiled materials for potential reuse. • Beneficial or managed reuse of concrete and asphalt on Lot 1 will not be conducted. Remaining concrete and asphalt will be reused on other portions of the Brownfields Property under separate plans. If the need arises for managed reuse of concrete and asphalt on Lot 1, it will be included under a separate plan as an addendum to this EMP. • The overall soils an inert debris management strategy is to reuse these materials on the Brownfields Property. The EMP includes a provision to potentially export excess soils and material to a nearby non-Brownfields sister Site (TIP-2). • The WWTP will remain operational until the remaining concrete slabs on Lot 2 are removed at a later date per a separate pending EMP. To support development of Lot 1, the existing wastewater line on the southern edge of the proposed building will be decommissioned. A temporary line will be constructed in it's place to keep the WWTP operational • Current assessment data does not indicate an unacceptable vapor intrusion risk for Lot 1. As such, and pending North Carolina Brownfields Program (NCBP) approval, design and installation of a Vapor Intrusion Mitigation System (VIMS) will not be included for redevelopment of Lot 1. 4) Do plans include demolition of structure(s)?: ® Yes ❑ No ❑ Unknown ® If yes, please check here to confirm that demolition will be conducted in accordance with applicable legal requirements, including without limitation those related to lead and asbestos abatement that are administered by the Health Hazards Control Unit within the Division of Public Health of the North Carolina Department of Health and Human Services. If available, please provide a copy of your demolition permit. 5) Are sediment and erosion control measures required by federal, state, or local regulations? ® Yes ❑ No ❑ Unknown ® If yes, please check here to confirm that demolition will be conducted in accordance with applicable legal requirements. If soil disturbance is necessary to install sediment and erosion control measures, they may not begin until this EMP is approved. 6) Which category of risk -based screening level is used or is anticipated to be specified in the Brownfields Agreement?

Soil 1) Known or suspected contaminants in soil (list general groups of contaminants): Assessment results for Lot 1 indicate little to no impacts from historical Site industrial activities. Contaminants, primarily metals, appear to localized and potentially naturally occurring. Potential exists for relatively low concentrations of petroleum and chlorinated solvents to be present as documented in previous assessment reports. 2) Depth of known or suspected contaminants (feet): Impacts, if present, are likely to be associated with the construction and debris type fill in Area #37. This fill generally appears to be located within five feet of the current land surface. Isolated impacts, I present, may also potentially be associated with the wastewater line. The remainder of the Lot 1 Site is likely to have not been impacted at unacceptable levels by historical operations. 3) Area of soil disturbed by redevelopment (square feet): The total disturbed acreage of the Lot 1 Site is 45.828. 4) Depths of soil to be excavated (feet): Maximum 15 feet BLS 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): An estimated 95,000 cubic yards of soil will be excavated during Site grading and undercut of unsuitable soils (U) and excavation of proposed Water Quality Devices (WQD) on Lot 1. Excess soils will be used, in part, to backfill Area #37. Remaining excess soils will be stockpiled in the Fill Area #1 and/or Fill Area #2 areas on adjacent portions of the Brownfields Property as shown on Figure 1. The WWTP (including ponds/lagoons) will remain operational during initial construction of Lot 1. As such, soils stockpiled in Fill Area #1 will not be placed in the ponds/lagoons, but will be available for future WWTP closure. Fill Area #2 will also be available for stockpiling as needed. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: The volume of soil impacted by contaminants cannot be reasonably estimated at this time but is likely to be limited to localized areas. As described in this EMP, measures to manage potentially impacted soil will be included in the event that field observations indicate the potential presence of impacted soil during Site work. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Assumption - Likely less than 5,000 cubic yards and will likely be limited to soil mixed with debris that is unsuitable for potential reuse. Part I.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 EMP Version 2, January 2021 provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are acceptable, if only preliminarydata 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). ..IIL.K UI Ldp IICIC LU CIILUI LCXL ❑ If yes, do the soils exceed the "Contained -Out" levels in Attachment 1 of the North Carolina Contained -In Policy? ................................................. ❑ Yes ❑ No b) NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS THE CONTAINED -OUT LEVELS IN ATTACHMENT 1 TO THE NORTH CAROLINA CONTAINED -IN POLICYTHE SOIL MAY NOT BE RE -USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS. c) Does the soil contain a CHARACTERISTIC WASTE? .................................... ❑ Yes © No ❑ If yes, mark reason(s) why below (and include pertinent analytical results). ❑ Ignitability Click or tap nere to enter texL ❑ Corrosivity Click or tap here to enter text. ❑ Reactivity Click or tap here to enter text. ❑ Toxicity Fick or tap here to enter text. ❑ TCLP results 'lick or tap here to enter text. ❑ Rule of 20 results (20 times total analytical results for an individual hazardous constituent on TCLP list cannot, by test method, exceed regulatory TCLP standard) Click or tap here to enter text. ® If no, explain rationale: Based on existing assessment data maintained by NCDEQ d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE SOIL MAYNOT BE RE -USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH DEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS. 2) Screening criteria by which soil disposition decisions will be made (e.g., left in place, capped in place with low permeability barrier, removed to onsite location and capped, removed offsite): ❑ Preliminary Health -Based Residential SRGs 10 EMP Version 2, January 2021 ® Preliminary Health -Based Industrial/Commercial SRGs ® Division of Waste Management Risk Calculator (For Brownfields Properties Only) ❑ Site -specific risk -based cleanup level. Please provide details of methods used for determination/explanation. Click or tap here to enter text. Additional comments: Based on available data, if construction activities encounter contaminated soil, it will likely be limited in area and volume. As described in the following section, field screening will be used to evaluate if soils and debris appear to be non -impacted and can be reused as backfill on other portions of the Brownfields Property. 3) If known impacted soil is proposed to be reused within the Brownfields Property Boundary, please check the measures that will be utilized to ensure safe placement and documentation of same. Please attach a proposed location diagram/site map. ® Provide documentation of analytical report(s) to Brownfields Project Manager ® Provide documentation of final location, thickness and depth of relocated soil on site map to Brownfields Project Manager once known ❑ Geotextile to mark depth of fill material.

Please provide a description of the measure: Survey data as needed 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: Standard construction techniques for dust control. ❑ No, explain rationale: lick or `-- '--- `- inter text. 11 EMP Version 2, January 2021 Field Screening of site soil ® Yes, describe the field screening method, frequency of field screening, person conducting field screening: Click or tap here to enter text. During construction, an EP will be present for initial excavation activities to make field observations and field screen soils using PID headspace and ambient air methods to evaluate for evidence of impacts, particularly during excavation of sol and debris from Area #37, soils adjacent to the WWTP waste water line, and management of soils in the deepest excavation areas and closest to known/potential contaminant sources associated with previous industrial use of the site. The level of on -site EP oversight may decrease if initial screening results consistently suggest a lack of impacts. Based on previously discussed existing assessment data, it is unlikely that an EP will be required on -Site for all earthwork activities. Based on initial observations during construction, the EP will work with the PD and construction personnel (Contractor) to determine the scope and frequency for subsequent oversight to reasonably document that remaining soils are managed in accordance with this EMP. This may include moving to standby and allowing the site Contractor or contractor designated representative to provide primary oversight of construction activities. The Contractor or designated representative will notify the EP if field conditions are encountered that could indicate the potential presence of impacted soil (i.e. staining). While on standby, the Contractor of designated representative will fill out a weekly log approved by the EP and provide photo log (as necessary) to document Brownfields Property conditions. The weekly reports will be included in a final EMP Implementation Report at the end of the project. While on standby, the EP will initially make weekly site visits, at a minimum, to document Brownfields Property conditions reported by the Contractor. The need and frequency of standby EP visits will be adjusted as needed based on site conditions encountered during site construction. ❑ No, explain rationale: Click or tap here to enter Soil Sample Collection ® Yes, describe the sampling method (e.g., in -situ grab, composite, stockpile, etc.): Based on previously described assessment results, no additional sample collection is currently planned unless the following conditions are encountered: Field Evidence of Potential Soil Impacts: If field evidence indicate the potential presence of soil impacts that are not consistent with previous assessment findings, the soil will either be 1) transported to a NCDEQ permitted facility for disposal; or 2) sampled and 12 EMP Version 2, January 2021 evaluated as potential on -Site fill. Under these conditions, the soil will be stockpiled for sampling. Segregation methods utilized by the Contractor to separate debris and/or use roll -off boxes. Stockpiling will be conducted in general accordance with NCDEQ guidance using the analytical laboratory methods included in this EMP for import sampling. Additional Data to Support Soil Export to Another Site (TIP-2): Based on current site grading plans, this scenario is considered unlikely. However, if excess soil is generated during site grading, additional soil sampling may potentially be needed to support export of soil to the TIP-2 non-Brownfields property or potentially another Brownfields property as beneficial fill and/or fill. Sampling would only be conducted if additional data is needed to evaluate if Brownfields Property soil increases risk at the receiving property. Primary reliance on existing Phase II Assessment data will be used be used to satisfy this requirement. If necessary, stockpile sampling will be conducted in accordance with NCDEQ guidance using the analytical laboratory methods included in this EMP for import sampling to support this effort. Additional details are provided under the Soil Export section of this EMP. Soil Import to Lot 1 Site From Other Portions of Brownfields Property: If additional soil is needed for construction work on the Lot 1 Site, the soil will either be obtained from the Stockpile of soil already developed from previous Lot 1 construction work or it will be obtained from the construction of the other WQD, undercut and/or Cut areas identified on Figure 1. An EP will screen soils for evidence of impacts prior to placement. If soils from other portions of the Brownfields Property are needed, they will be placed at depth at least two feet below final grade elevation. If soils will be used to establish the final two feet of final grade, they will either be from previously sampled stockpiled soil with acceptable laboratory test results (i.e. per risk calculator evaluation) or they will be sampled in -situ per final landscape sampling. ❑ No, explain rationale: 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 ❑ Pesticides: Specify Analytical Method Number(s): ❑ PCBs: Specify Analytical Method Number(s): 13 EMP Version 2, January 2021 Click or tap here to enter text ® Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Specify Analytical Method Number(s): Antimony by EPA Method 6020, Hexavalent chromium by EPA Method 7199, and 1,4-Dioxane by 8260 SIM. ® 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.

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, indicate if a work plan for final grade sampling may be submitted under separate cover. A work plan will be submitted under separate cover pending field observations during construction. ❑ If final grade sampling was NOT selected, please explain rationale: 14 EMP Version 2, January 2021 Part 1.13. 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? 3) If yes, what is the anticipated depth that fill soil will be placed at the property?

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. It is estimated that rock quarry aggregate will be imported to the onto the Brownfields Property. Available information indicates that imported soils will not be imported onto the Brownfields Property. Stone aggregate will obtained from Wake Stone Corporation or another NCBP approve - quarry. 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. At this time, if impacted soil is encountered, the soil will be exported to a NCDEQ permitted facility for disposal purposes. Additional Data to Support Soil Export to Another Site (TIP-2): Based on current site grading plans, this scenario is considered unlikely. However, if excess soil is generated during site grading, additional soil sampling may potentially be needed to support export of stockpiled soil to the TIP-2 non-Brownfields property or potentially another Brownfields property as beneficial fill and/or fill. Sampling would only be conducted if additional data is needed to evaluate if Brownfields Property soil increases risk at the receiving property. Stockpile sampling will be conducted in accordance with NCDEQ guidance using the analytical laboratory methods included in this EMP for import sampling to support this effort. Additional NCBP and Solid Waste Section correspondence and approval may be required to establish data needs and sampling frequency. The sampling strategy and level of effort for sampling both export soils and background soil conditions on receiving sites (as needed) will likely depend on the characteristics of the receiving site. Additional correspondence will be used to establish a final sampling frequency of 1 sample per 250, 500, 750, or 1,000 cubic yards or other approved sampling ratio. 16 EMP Version 2, January 2021 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 thata 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). See Item 1 under this Section Figure 2 provides the location of the TIP-2 potential soil export Site. Note that beneficial/managed reuse of concrete and asphalt from the Brownfields Property to the TIP-2 property may potentially be requested. If so, this will be conducted under a separate EMP and/or document for NCBP approval. Part I.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 nota 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 or provide the results of this evaluation in the Vapor Mitigation Plan. Note that if vapor mitigation is planned for site buildings, utility corridors will need to be evaluated as part of mitigation designs: 17 EMP Version 2, January 2021 Per the approved 9 August 2021 EMP utility EMP Trench dams will be constructed for the main line water, sewer, electrical, natural gas and communication line excavations that are backfilled with a stone aggregate to mitigate the potential risk of lateral vapor migration outside the of the area of the documented groundwater plume. Please refer to this EMP for additional details. ❑ If no, include rationale here: Click or tap here to enter text. ❑ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings Other comments regarding managing impacted soil in utility trenches: Potentially impacted soils will not be placed back into trenched if they represent a potential vapor risk. PART 2. GROUNDWATER 1) What is the depth to groundwater at the Brownfields Property? Available data reports that the approximate groundwater depth is between 1 to 18 feet bgs. However, underlying Triassic geological conditions may be creating confined groundwater conditions, and as such, the actual depth of groundwater is likely to be at greater depths. Based on this information, excavations are anticipated not to encounter the water table. Field observations during construction will be used to confirm this assumption. 2) Is groundwater known to be contaminated by ®onsite ❑offsite ❑both or ❑unknown sources? Describe source(s): Yes — as documented in assessment reports maintained by the NCBP 3) What is the direction of groundwater flow at the Brownfields Property? On the western portion of the Brownfields Property, estimated groundwater flow will follow topography moving west-southwest. On the eastern portion of the Brownfields Property, estimated groundwater flow will follow topography moving east -south east. 4) Will groundwater likely be encountered during planned redevelopment activities? ❑Yes ®No If yes, describe these activities: 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., dewateringof groundwater from excavations or foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or sampling procedures). In the event that groundwater is encountered, it will be displaced in the excavation and/or pumped into a tanker truck, frac tank or other container approved by the EP. Sampling and analysis will be conducted by the EP as needed to characterize the water for disposal purposes 18 EMP Version 2, January 2021 based on the requirements of the disposal facility. The on -site wastewater treatment plant (WWTP) may be used to treat containerized groundwater pending analytical results and regulatory approval. 5) Are monitoring wells currently present on the Brownfields Property? ................. ❑X 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. It is the Brownfields Program's intent to allow proper abandonment of well(s) as specified in the Brownfields Agreement, except if required for active monitoring through another section of DEQ or the EPA. ® Location of existing monitoring wells marked ® Existing monitoring wells protected from disturbance ® Newly identified monitoring wells will be marked and protected from further disturbance until notification to DEQ Brownfields can be made and approval for abandonment is given. 7) Please provide additional details as needed: Monitoring wells will be protected and abandoned on an as -needed basis. Please note, disturbance of existing site monitoring wells without approval by DEQ is not permissible. If monitoring wells are damaged and/or destroyed, DEQ may require that the PD be responsible for replacement of the well. PART 3. SURFACE WATER 1) Is surface water present at the property? ® Yes ❑ No ❑ Unknown 2) Attach a map showing the location of surface water at the Brownfields Property. 3) Is surface water at the property known to be contaminated? ® Yes ❑ No 4) Will workers or the public be in contact with surface water during planned redevelopment activities? ❑ Yes ® No 5) In the event that contaminated surface water is encountered during redevelopment activities, or clean surface water enters open excavations, list activities for management of such events (e.g. flooding, contaminated surface water run-off, stormwater impacts): Available information indicates impacted surface water is not present at the Site. As such, impacted surface water scenarios would only occur during a rainfall event during excavation 19 EMP Version 2, January 2021 activities that encounter potentially impacted soil. If areas of impacted soil are encountered during construction, as needed, they will be covered with plastic by the Contractor to prevent direct contact with rain/surface water while soil grading activities are occurring. Stockpiles will be managed per Figure 1 of this EMP. If applicable, water that has contacted impacted soil will be contained on -site using diking, trenching and/or will be allowed to infiltrate into soils or placed into a tanker truck, frac tank or other storage container by the Contractor as approved by the EP. Pending regulatory approval, the waste water lagoons may also potentially be utilized to manage storm water from construction areas. If needed, water will be sampled by the EP for laboratory analysis to evaluate handling/disposal options. Sampling and analysis will be conducted based on the requirements of the disposal facility. As needed, the impacted area will be covered by at least two feet of soils that are not impacted by contaminants at unacceptable levels. PART 4.

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, orother 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 ❑ Pesticides: Specify Analytical Method Number(s): Cli& or tar, here to en+or fn, f ❑ 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. Antimony by EPA Method 6020, Hexavalent chromium by EPA Method 7199, and 1,4- Dioxane by 8260 SIM. Please provide details on the proposed methods of managing the following commonly encountered issues during redevelopment of Brownfields Properties. WWTP Waste Water Line Decommissioning: The waste water line on the central portion of Lot 1 will need to be decommissioned during construction. This will include using a bladder or equivalent 23 EMP Version 2, January 2021 to seal off the downgradient portion of the pipe to prevent sludge and sediment from flowing into the WWTP lagoon system. Once the waste water line has been reasonably sealed, sections of the lines will be removed. Interior sludges and water will be removed using a vacuum truck and pressure washer. Plastic sheeting will be used, as applicable, to minimize the contact of pipe contents with surrounding soils. If soils are impacted by pipe contents, they will be excavated for sampling and/or disposal per the requirements set forth in this EMP. The EMP will provide oversight of the waste water line decommissioning process using the field screening procedures described in this EMP to evaluate Site conditions to support construction activities. The EP will provide approvals for the excavation to be backfilled. Underground Storage Tanks: Available information indicates that it is unlikely for USTs to be present at the site. In the unlikely event that a UST is identified, UST closure and corrective action will be followed per applicable NCDEQ UST Section regulations and guidance. This may include the use of a mobile laboratory with Ultra -Violet Fluorescent (UVF) capabilities to help determine the extent of impacts in the field. Confirmatory soil samples will be collected from four sidewalls and at least one base sample (depending on size) of the final excavation. Confirmation analysis will include VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA Metals by EPA Methods 6020 and 7471, and Hexavalent Chromium by EPA Method 7199, as applicable, to meet NCBP requirements. Additional analysis may include those listed in UST Section Guidance, Table 3. Approved Methods for Soil Analyses at Petroleum UST Closures and Over -Excavation and at Site Checks (https://files.nc.gov/ncdeq/Waste%20Management/DWM/UST/Corrective%20Action/ACA%20table s%20Ch ng3 % 20112013. pdf). Sub -Grade Feature/Pit: Because of the historical use of the Brownfields Property, it is unlikely for sub -grade features/pits to be encountered beyond what has already been identified under previous assessment reports. In the event that such features are identified, they will be handled under Guidelines for Assessment and Cleanup of Contaminated Sites (NCDEQ IHSB, January 2020) (https://files.nc.gov/ncdeq/Waste%20Management/DWM/SF/IHS/guidance/IHSB RemediationGuid ance012720.pdf) Buried Waste Material — Note that if buried waste, non-native fill, or any obviously filled materials is encountered, the DEQ Brownfields Program must be notified to determine if investigation of landfill gases is required: The NCBP will be notified in the event that buried wastes are encountered other than for the conditions previously described in this EMP. Work will be stopped and plans will be conducted to evaluate the waste if the EP believes that the characteristics of the material is inconsistent with data from previous assessment reports. Re -Use of Impacted Soils On -Site: Grossly impacted soils will not be re -used on -Site. Per the procedures identified in this EMP, the EP will screen soils to evaluate the presence of impacts, if any, and appropriate re -use scenarios. 24 EMP Version 2, January 2021 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 I.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: NA POST -REDEVELOPMENT REPORTING ® Check this box to acknowledge that a Redevelopment Summary Report will be required for the project.
