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. Extensive site sampling and assessment has been completed associated with the 2011 BFA, MGP IHSB cleanup, and LUST response action and NFA. Additional sub-slab soil gas sampling will be conducted in the Clancy & Theys shop area and former Amtrak building, and soil sampling will be completed in the area where a swimming pool will be constructed at the depth of maximum disturbance. Separate workplans for these assessment activities will be provided. ☒ Specific redevelopment plans, even if conceptual, have been developed for the project, submitted and reviewed by the Brownfields Project Manager. Please submit, along with the completed EMP form, the following attachments, as relevant and applicable to the proposed redevelopment: 2 | P a g e ☒ A set of redevelopment plans, including architectural/engineering plans, if available; if not conceptual plans may suffice if updated when detailed plans are drafted. ☒ A figure overlaying redevelopment plans on a map of the extent of contamination for each media. ☒ Site grading plans that include a cut and fill analysis. ☒ A figure showing the proposed location and depth of impacted soil that would remain on site after construction grading. ☐ Any necessary permits for redevelopment (i.e. demolition, etc.). ☒ A detailed construction schedule that includes timing and phases of construction. ☒ Tabulated data summaries for each impacted media (i.e., soil, groundwater, soil gas, etc.) applicable to the proposed redevelopment. ☒ Figures with the sampling locations and contamination extents for each impacted media applicable to the proposed redevelopment. ☐ A full final grade sampling and analysis plan, if the redevelopment plan is final. ☐ If known, information about each proposed potential borrow soil source, such as aerial photos, historic site maps, historic Sanborn maps, a site history, necessary for brownfields approval. ☐ Information and, analytical data if required, for quarries, or other borrow sources, detailing the type of material proposed for importation to the Brownfields Property. ☐ A work plan for the sampling and analysis of soil to be brought onto the Brownfields Property. Refer to Issue Resolution 15 in Brownfields Program Guidelines. ☒ A map of the Brownfields Property showing the location of soils proposed for export and sampling data from those areas. ☒ If a Vapor Mitigation System is required by the Brownfields Program, the Vapor Intrusion Mitigation System (VIMS) plan will be signed and sealed by a NC Professional Engineer. The VIMS Plan may also be submitted under separate cover. (To be submitted under separate cover.) 3 | P a g e Date: April 8, 2021 Revision Date (if applicable): Click or tap to enter a date.

The MGP operations caused contamination due to spillage and onsite disposal of tars and other wastes. By 1989, PSNC Energy Company had dismantled all MGP equipment and structures. Starting in 2001 and culminating in 2011, PSNC implemented four large-scale cleanup actions that included removal and offsite disposal of approximately 54,000 tons of contaminated material and using treatment reagents to degrade the remaining pollution. The remediation was overseen by DEQ’s Waste Management Division, IHSB, Special Remediation Branch. The past cleanup actions removed much of the contamination caused by the MGP operations. Remediation was conducted across the former MGP footprint and the cleanup areas were backfilled and covered with clean fill to allow site reuse and redevelopment. Nevertheless, un- remediated contamination remains in some areas below the ground surface in soil and groundwater. 1 From the 1800’s through the mid-1900’s, before natural gas was available as an energy source, manufactured gas plants (MGPs) existed throughout North Carolina and the United States. These plants used coal and oil to produce a burnable gas for lighting, heating, and cooking. Legacy environmental problems were common at MGP locations. CONTAMINATED MEDIA 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. 7 | P a g e In addition to the MGP operations, there were leaking underground storage tanks (USTs) located next to the Clancy & Theys office building. Clancy & Theys removed the USTs in 1989, responded to the release and received a Notice of No Further Action (NFA) from DEQ in 2010. Residual petroleum contamination remains in soil and groundwater in and around the UST cleanup area. Specific pollutants that remain above DEQ standards and guidelines include chlorinated solvents, BTEX compounds and polyaromatic hydrocarbons (PAHs). The cleanup areas and the remaining residual pollution is shown in the attached Brownfields Survey Plat as Figure 3. Known residual contamination in relation to the existing and proposed stormwater culverts and other site features is also shown in Figure 4. The extend of the MGP cleanup and areas of clean fill and the location of the UST tank graves are shown in Figure 5, which also shows the brownfields site boundaries that will be established by recombination. 2) Depth of known or suspected contaminants (feet): Contamination extends into the underlying groundwater and may be present from 5-20 bgs. 3) Area of soil disturbed by redevelopment (square feet): 4) Depths of soil to be excavated (feet): 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: A total of 14,400 cubic yards • 50% of Foundation Spoils [2,200 CY] • 100 % of Deep Foundation Spoils [2,200 CY] • Culvert trench - [10,000 CY] 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: Up to 14,400 cubic yards (10,000 cu yd from the culvert trench + 4,400 cu yd from foundations spoils) may be disposed offsite. However, we will be evaluating the suitability of beneficial reuse Approximate 100,000 sq ft (2 acres) of land area may be disturbed for grading where material will be “cut” from the northern portion of the site to provide fill to increase the grade in the southern portion. Construction of a new stormwater culvert will disturb an additional 25,000 sq ft of the property for a 25-foot wide by 1,000 linear feet long trench excavated for the culvert. Proposed grading will include excavations of up to approximately 11 ft in the northern portion of the site that will occur in previously remediated areas now covered with clean fill. Footings/pilings/foundations: up to 4 feet below existing grade. The culvert excavations will extend to 15 ft to 20 ft below ground surface. Most of the culvert construction is in previously remediated portions of the site, but subsurface contamination may be encountered. See Figure 6a and 6b for site grading and Figure 7 for the box culvert. The total to be excavated is 29,600 cubic yards, including grading, foundations and culvert trenching • Foundation Spoils [4,400 CY] • Deep Foundation Spoils [2,200 CY] • Cut to Fill [9,000 CY] – assumed to be clean fill • Fill disturbed for the culvert trench [14,000 CY] 8 | P a g e during construction. This will occur in real time as work is underway when we can observe materials and evaluate structural suitability for reuse. For material excavated from the culvert, in particular, we will follow DEQ’s “last-out, first-in” principle for both clean and impacted soils that are geotechnically and structurally suitable for reuse. Where possible, impacted soils will be used as below-grade backfill in the culvert trench. Therefore, the estimated volume of contaminated soil for disposal may be decreased. 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). Click or tap 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 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 POLICY THE SOIL MAY NOT BE RE-USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITHDEQ 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 here to enter text. ☐ Corrosivity Click or tap here to enter text. ☐ Reactivity Click or tap here to enter text. ☐ Toxicity Click or tap here to enter text. ☐ TCLP results Click 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. Part 1.A. MANAGING ONSITE SOIL 9 | P a g e If no, explain rationale: The Toxicity Characteristic Leaching Procedure (TCLP) is not used for determining whether material impacted by manufactured gas plant (MGP) waste is hazardous. MGP-impacted material is considered a solid waste, but not hazardous. As outlined above, we plan to evaluate the possible reuse of impacted soil (especially associated with the culvert trench work) following DEQ’s “last-out, first-in” principle. 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 ☐ 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: Click or tap here to enter text. 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. Provide description of material: Click or tap here to enter text. ☒ Manage soil under impervious cap ☒ or clean fill ☒ ☒ Describe cap or fill: Impacted material may be returned to the below-grade excavation areas as backfill where it originated associated with the stormwater culvert and other utilities. Impacted material may also be reused as below-grade structural fill under parking and other impervious services. 10 | P a g e ☒ Confer with NC BF Project Manager if Brownfield Plat must be revised (or re- recorded if actions are Post-Recordation). ☒ GPS the location and provide site map with final location. ☐ Other. Please provide a description of the measure: Click or tap here to enter text. 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: ☐ 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: Traditional construction erosion and dust management practices including wetting of soils to prevent dust creation. Stormwater Culvert - During trenching for the culvert, full-time field screening will be conducted. Unsaturated overburden soil not displaying indications of impacts will be stockpiled and saved for reuse as trench backfill. Saturated fill may be temporarily stockpiled and dewatered or otherwise conditioned to address high moisture content before being loaded for offsite disposal. We will, however, be evaluating reuse of all suitable fill (both clean and impacted) under DEQ’s “last-out, first-in” principle. Foundations – Shallow foundation spoils will be field screened and spoils not displaying indications of impacts will be stockpiled and saved for reuse as onsite backfill. Deep foundation spoils will be assumed to be impacted and will be temporarily stockpiled and loaded for offsite disposal. General Grading – Much of the site was remediated and covered with clean fill or is believed to be unimpacted- including the western portion of the property outside of the footprint of the former MGP facility or USTs (See Figures 3, 4 & 5). Grading will consist of lowering the grade in the northern portion of the site and using the graded material to increase the grade elevation to the south. Grading is “balanced” meaning if was designed for the cut and fill quantities to be equal with no net import or export. During grading, the general contractor and grading contractor will observe for evidence of potential impacts, such as staining, odors, or waste disposal. If a concern is noted, the contractor will contact the environmental engineer to investigate the suspect condition. If the environmental engineer confirms that material is impacted, then the procedures below will be implemented. 11 | P a g e Soil Sample Collection ☒ Yes, describe the sampling method (e.g., in‐situ grab, composite, stockpile, etc.): Historical assessment activities have provided extensive data to characterize the site and to allow fill management decision making. This includes the extensive testing associated with the 2011 BFA, the four phases of MGP cleanups and LUST response action near the Clancy & Theys office, which resulted in an NFA. Additional soil samples will be collected to the depth of maximum disturbance beneath the proposed pool location. A workplan for the pool-area sampling will be provided to DEQ for review and approval. Additional sampling and analysis may be conducted on an as-need basis for the following: • There may be the need to collect and analyze additional samples as required to obtain offsite disposal approvals. The particular sampling and analyses will be dictated by the particular disposal site’s requirements. • Additional testing may be conducted at the direction of a CIH or other contractor safety professional to provide information for hazard assessments and site safety procedures. • We know that some portion of the fill excavated for foundations and the culvert trench, in particular, will be impacted. We have planned accordingly and have suitable data from post-cleanup sampling and analyses conducted for the MGP and UST cleanups to inform the fill management procedures outlined in this EMP, which include disposal and onsite reuse. But at the direction of the environmental professional or DEQ, additional testing may be conducted if unforeseen conditions are encountered or to otherwise help with fill management decision making. Sampling would follow IHSB guidelines and could include insitu, grab, discrete and composites sampling, depending on the situation. Samples may be analyzed for VOC, SVOCs, RCRA metals and hexavalent chromium. Additional testing, as may be needed, would be summarized in a plan and provided to DEQ for approval ☐ 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 6020/7471 ☐ 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. 12 | P a g e ☒ 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: Click or tap here to enter text. ☒ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or permanent hardscape). Select chemical analyses for final grade samples with check boxes below (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, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Method 6020/7471 ☒ Pesticides: Specify Analytical Method Number(s): Organochlorine pesticides (OCPs) by EPA Method 8081 ☐ 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 by EPA Method 7199 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? (If a range of depths, please list the range.) 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: We have designed grading to be balanced and construction plans minimize the need for fill import. Some structurally suitable import material may be needed to achieve final-grade elevations and other structural applications. We expect this would be 2000 cubic yards or less. Clean imported fill may be placed as backfill at depths up to 20 ft in the culvert trench, and up to 10 ft elsewhere at the site. Suitable onsite materials will be used where possible for backfilling before structural fill will be imported. 13 | P a g e 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. 6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): EPA Method 6020/7471 ☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text. ☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Hexavalent Chromium by 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. 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 borrow source for fill material (if needed) is not known at this time. Upon determination of the borrow source, DEQ will be notified and the procedures outlined below will be implemented. If possible, we will use DEQ pre-approved fill suppliers, including Wake Stone’s Knightdale facility. We will first seek to use fill suppliers which are DEQ-approved. If a candidate fill supplier is not DEQ-approved, we will provide an analysis plan to demonstrate the fill meets acceptable standards. Also, for permitted quarries, if not a pre-approved supplier, but on the DEMLR mining inventory list, in lieu of submitting an analysis plan, one three-point composite sample representative of the fill for metals and SVOCs and one discrete representative sample for VOCs will be collected. (see: https://deq.nc.gov/about/divisions/energy-mineral-land- resources/energy-mineral-land-permits/mining-program) There is some possibility that we will seek DEQ pre-approval to receive alternative fill, including from another nearby NC Brownfields site. We currently have no specific plans for this, but there are several active brownfields sites in greater Durham, and some will be generating excess fill. We will provide a separate sampling plan if needed. Part 1.C. EXPORTED SOIL 14 | P a g e 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. 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). ☐ Install liner between native impacted soils and base of utility trench before filling As indicated above, 14,400 cubic yards (Assuming 10,000 cu yd from the culvert trench + ½ of the foundations spoils+100% of deep foundation spoils) may be exported for offsite disposal. The quantity exported my be reduced if safe onsite reuse is possible. We are evaluating ways to reuse impacted but otherwise geotechnically suitable fill material in a safe manner to minimize offsite disposal. This includes reusing material as backfill in utility excavations and as below-grade structural fill following DEQ’s last out, first in approach. We currently do not anticipate export of Brownfields soil for beneficial offsite reuse. Soil and fill transported from the site will be disposed. Part 1.D. MANAGEMENT OF UTILITY TRENCHES 15 | P a g e 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: Other comments regarding managing impacted soil in utility trenches: 1) What is the depth to groundwater at the Brownfields Property? Groundwater is shallow and may be encountered a 6 ft below ground surface. 2) Is groundwater known to be contaminated by ☒onsite ☒offsite ☒both and ☒unknown sources? Describe source(s): Groundwater is contaminated by the former MGP, onsite UST releases and other possible onsite and offsite sources. 3) What is the direction of groundwater flow at the Brownfields Property? 4) Will groundwater likely be encountered during planned redevelopment activities? A large trench will be excavated for the installation of a new stormwater box culvert through the center of the site. Unsaturated overburden soil/fill in the areas where the new convert will be built is expected to be predominantly uncontaminated based on the prior MGP cleanup work. Some portion of the saturated soil/fill removed from below the water table for the culvert trench may be impacted and/or geotechnically unsuitable for re-use. Impacted material that is not a candidate for beneficial reuse as backfill following DEQ’s “last-out, first-in” principle, will be removed, stockpiled and transported for offsite disposal. The contractor will observe all soil for potential impacts during utility installation. Evidence of potential impacted soil includes a staining, strong odors, waste materials or other concerns (i.e. chemicals, tanks, drums, etc.). Should the above be noted, the contractor will contact the environmental engineer. If the environmental engineer confirms that the material may be impacted, then the procedures outlined Managing On-Site Soil above 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. Groundwater flow is north to south PART 2. GROUNDWATER – Please fill out the information below. 16 | P a g e ☒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., dewatering of groundwater from excavations or foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or sampling procedures). 5) Are monitoring wells currently present on the Brownfields Property? .............. ☒Yes ☐No 6) If yes, are any monitoring wells routinely monitored through DEQ or other agencies?................................................................................................................ ☒Yes ☐No 7) Please check methods to be utilized in the management of known and previously unidentified wells. ☒ Abandonment of site monitoring wells in accordance with all applicable regulations. It is the Brownfields 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. 8) Please provide additional details as needed: 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. Groundwater will be encountered during redevelopment activities including, most importantly during construction of the stormwater box culvert. Groundwater may be encountered during work on foundations. Dewatering will be needed for the construction of the stormwater culvert and may be needed for other foundation construction. Contaminated groundwater dewatering will be collected, pretreated and discharged to the City of Raleigh POTW under a temporary Industrial User Permit. A copy of the permit and all associated analytical data and reports will be provided to DEQ. There are nine wells that are sampled associated with the IHSB MGP cleanup completed in 2011. Semiannual sampling is conducted by Hart & Hickman on behalf of Dominion Energy. We have consulted with Hart & Hickman to review the location of the wells and status of ongoing monitoring obligations. Some of the IHSB wells are in areas of redevelopment and will be properly abandoned. As needed, we will ensure the wells continue to be available for monitoring or provide new wells based on review with Hart & Hickman and DEQ IHSB officials. 17 | P a g e 1) Is surface water present at the property? ☐Yes ☒ No 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): 1) Are sediment sources present on the property? ☐ Yes ☒ No 2) If yes, is sediment at the property known to be contaminated: ☐ Yes ☒ No 3) Will workers or the public be in contact with sediment during planned redevelopment activities? ☐ Yes ☒ No 4) Attach a map showing location of known contaminated sediment at the property. 5) In the event that contaminated sediment is encountered during redevelopment activities, list activities for management of such events (stream bed disturbance): Do concentrations of volatile organic compounds at the Brownfields property exceed the following vapor intrusion screening levels (current version) in the following media: IHSB Residential Screening Levels: Soil Vapor:………..☐ Yes ☐ No ☒ Unknown Groundwater:.….☒ Yes ☐ No ☐ Unknown IHSB Industrial/Commercial Screening Levels: Contaminated groundwater and precipitation will accumulate in the stormwater culvert excavation area and may accumulate in other foundation construction areas. As indicated above, dewatering will be needed for the construction of the culvert and may be needed for other foundation work. Accumulated water will be collected, pretreated and discharged to the City of Raleigh POTW under a temporary Industrial User Permit. Conventional stormwater management will be addressed by the NPDES General Construction Permit issued by the City of Raleigh and associated erosion and sedimental controls that will be implemented.

Most importantly, for subsurface work, ground disturbance and excavations below the water table. Construction crews working on the culvert subsurface construction, in particular, have the highest potential for encountering contaminated media. Contractors engaged in ground disturbing activities, including the culvert work, excavations, foundation construction and grading, will comply with the applicable provisions of Occupational Health and Safety Administration (OSHA) regulations, as well as all other applicable federal, State of North Carolina and local safety regulations. To comply with OSHA requirements for protection of their work force, contractors and their safety managers will review site conditions, conduct a workplace exposure assessment and plan for OSHA compliance and worker protection and training. Control measures, among others, can include limiting disturbed area (such as during trenching/backfilling), temporarily covering exposed saturated soils if areas not ready for final backfill, the use of personal protective equipment, mitigation measures such as venting, and limiting worker entry into trenches and other subsurface work areas as much as is feasible.

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, Based on the contaminant levels at the site, exposure to vapors is likely during construction and, as a result, safety and mitigation measures will be implemented during construction. For new improvements and construction, a protective VIMS will be installed at the site. Design of the VIMS will be provided separately. VAPOR INTRUSION MITIGATION SYSTEM – Please fill out the information below. PART 7. INDOOR AIR – Please fill out the information below. CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials 20 | P a g e and/or other officials, as necessary and appropriate, is required when new potential source(s) of contamination are discovered. These Notification Requirements were outlined on Page 1 of this EMP. Should potentially impacted materials be identified that are inconsistent with known site impacts, the DEQ Brownfields Project Manager will be notified and a sampling plan will be prepared based on the EMP requirements and site-specific factors. Samples will generally be collected to document the location of the potential impacts. Check the following chemical analysis that are to be conducted on newly identified releases: ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver) EPA Method 6020 and EPA Method 7471 ☒ Pesticides: Specify Analytical Method Number(s): Organochlorine pesticides (OCPs) by EPA Method 8081 ☐ 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. Underground Storage Tanks: If a UST is encountered, the environmental professional will be consulted to determine the appropriate course of action. In addition, the Brownfield Program Project Manager will be informed. The UST will be removed, disposed and the area in the vicinity of the UST assessed for evidence of a release. The sampling protocol will follow DEQ UST Section guidance; however, we anticipate the analysis of soil samples would be for VOCs, SVOCs, RCRA metals and Cr (VI) to allow for risk-based decision making. Sub-Grade Feature/Pit: If a sub-grade feature/pit is encountered, the environmental professional will be consulted to determine the appropriate course of action. In addition, the Brownfield Program Project Manager will be informed of the discovery. The feature/pit will be assessed to determine if environmental assessment or cleanup is warranted. 21 | P a g e Buried Waste Material: In the event buried waste is encountered, the environmental professional will be consulted to determine the appropriate course of action. In addition, the Brownfield Program Project Manager will be informed of the discovery. The nature of the waste will be evaluated to determine if environmental assessment or cleanup is warranted. Re-Use of Impacted Soils On-Site: Impacted soil may be reused onsite as backfill in accordance with the section above regarding impacted onsite soils management. 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.
