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): A cut/fill grading plan is included in Attachment C. Site maps with previous soil samples locations are included in Attachment B. Results of analysis of previous soil samples collected in 2006 and 2016 did not indicate the presence of compounds above DEQ IHSB Residential PSRGs (or typical background levels for metals). 2) Depth of known or suspected contaminants (feet): There are no known or suspected soil impacts at the site. 3) Area of soil disturbed by redevelopment (square feet): Grading will be conducted across the site prior to building construction. Grading activities will be conducted in accordance with a grading plan (see Attachement A) utilizing grading equipment (i.e. backhoes, front end loaders, bull dozers etc.) 4 EMP Form ver.1, October 23, 2014 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 on site. 4) Depths of soil to be excavated (feet): Based upon the preliminary cut/fill plan, cuts or up to 10 ft will occur at the site, although most of the cut will be in the range of 5 ft or less. 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): 3800 cubic yards 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: None anticipated. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: None anticipated. Based upon the grading plan and cut/fill drigram, a net import of approximately 6800 cubic yards of soil will be needed as part of site grading. IMPORTED FILL SOIL 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? 6,800 cubic yards 3) If yes, what is the depth of fill soil to be used at the property? Range of less than 1 ft to greater than 10 ft (see attached preliminary cut/fill plan in Attachment C). If a range of depths, please list the range. 4) PRIOR TO ITS PLACEMENT AT 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: Click here to enter text. ☐ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE): If soil is obtained from a known permitted quarry, then one soil sample will be collected from the borrow source prior to the soil being transported to the site. If fill soil is obtained from an off-site property that is not a known permitted quarry, a sampling plan will be developed and submitted for DEQ review. DEQ approval of the sampling plan and analytical results is required prior to bringing soil on site. The specific sampling rate will be outline in the above workplan, however generally if the proposed borrow source has not been previous developed (i.e. virgin land) soil samples at a rate of one per 500-1000 cubic yards can be used as an estimate. If the borrow source property has been previously developed, it should be estimated that soil samples will be collected at a rate of approximately one per 400 cubic yards. The burrow soil samples will be analyzed for VOCs, SVOCs, HSL Metals plus hexavalent chromium. Soil will be considered suitable for use at the site if it does not contain compound 5 EMP Form ver.1, October 23, 2014 concentrations above DEQ IHSB Residential PSRGs or typical background levels for metals from samples on the Brownfields Property or immediate surrounding area. 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 ☐ 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: Soil impacts are associated with former USTs that stored virgin petroleum products which are exempt from toxicity characteristic hazardous waste regulations. 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 4/1/2016 6 EMP Form ver.1, October 23, 2014 ☐ Preliminary Health-Based Industrial/Commercial SRGs Click here to enter a date. ☐ Site-specific risk-based cleanup level, or acceptable concentrations determined via calculated cumulative risk. Enter details of methods used for determination/explanation: NA 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: Contaminated soil is not expected to be encountered or disturbed during site redevelopment activities based upon previous soil sampling 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. In the unlikely event that contaminated soil is encountered during site redevelopment that requires excavation, particular attention will be paid by contractors to implement dust control measures and 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 contractors will observe soils for evidence of potential significantly impacted soil that may not be suitable to leave in place in exposed areas at a residential use site. Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or observance of 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 consultant to observe the suspect condition. If the project environmental consultant confirms that the material may be impacted, then the procedures below will be implemented. In addition, the environmental consultant will contact the DEQ Brownfields project manager within one business day to advise that person of the condition. ☐ Soil Sample Collection: ☐ Yes ☒ No If yes, describe method (e.g., in-situ grab, composite, stockpile, etc.); If no, explain rationale: H&H does not anticpate collecting additional soil samples prior to construction activities based on previous site assessment activities. If significant soil impact is encountered during grading and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading and/or construction of the utility to continue and/or only as far as needed to allow alternate corrective measures described below. Suspect significantly impacted soil excavated during grading and/or utility line installation or removal may be stockpiled and 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 hazardous substance list (HSL) 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 7 EMP Form ver.1, October 23, 2014 analyzed for toxicity characteristic leaching procedure TCLP VOCs and/or TCLP RCRA metals. Impacted soil will be handled in the manner described below based upon the laboratory analyses: 1) If no organic compounds are detected in a composite sample (other than which are attributable to sampling or laboratory artifacts) and metals are consistent with background levels, then the soil will be deemed suitable for use as on-site fill or as off-site fill. The proposed location(s) for off-site placement of soil (other than a permitted facility) along with the receiving facility’s written approval for acceptance of the soil will be provided to DEQ for approval prior to taking the soil off-site. 2) If detectable levels of compounds are found which do not exceed the DEQ IHSB Residential PSRGs (other than which are attributable to sampling or laboratory artifacts or which are consistent with background levels for metals) and the TCLP concentrations are below hazardous waste criteria, then the soil may be used on-site as fill without conditions. 3) If detectable levels of compounds are found which exceed the DEQ IHSB Residential 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 Residential 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. 4) Impacted soil may be transported to a permitted facility such as a landfill provided that the soil is accepted at the disposal facility. In the unlikely event that the composite 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: ☒ 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 EPA Priority Pollutant Metals. VOC and SVOC concentrations will be compared to DEQ Residential PSRGs. Metal concentrations will be compared to Residential PSRGs and typical background metal concentrations. 8 EMP Form ver.1, October 23, 2014 ☒ 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 or fill: No such placement is currently anticipated. If contaminated soil is encountered and will be placed under impervious soil or at least 2 ft of clean fill. Potential impervious caps at the site include the building foundations and paved areas. See attached site development plan in Attachment A. (provide location diagram) ☒ Confer with NC BF Project Manager if Brownfield Plat must be revised (or re- recorded if actions are Post-Recordation). ☐ Other: Note that impacted soil is that exceeds Residential PSRGs ☐ Final grade sampling of exposed soil (i.e., soil that will not be under buildings or permanent hardscape): [if not checked provide rationale for not needing] Provide diagram of soil sampling locations, number of samples, and denote Chemical Analytical Program 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 (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) ☐ Pesticides ☐ PCBs ☐ Other Constituents & Analytical Method: No final grade/post-construction sampling is proposed because most of the site will be covered by pavement and buildings. In addition, a significant amount of fill soil will brought to the site and cover much of the site, and the fill soil will have been documented as having concentrations below the Resdidential PSRGs. 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. 9 EMP Form ver.1, October 23, 2014 ☒ 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: Click here to enter text. ☒ 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: No particular Brownfields sites have been 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? Result: Yes □ No □ If no, include rationale here. Click here to enter text. If yes, provide specifications on barrier materials Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in the event contaminated soil and/or vapors are encountered in the utility trenches during redevelopment activities, the trench will be evacuated and appropriate safety screening of the vapors will be performed to protect workers. If results indicate further action is warranted in response to vapors to protect workers, appropriate engineering controls (such as use of industrial fans) will be implemented. PART 2. 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? Due to significant variation in current site topography, depth to groundwater at the site is in the range of approximately 12-42 ft bgs depending upon location at the site. After site grading, groundwater below the site will be present at depths of approximately 20 to 30 ft bgs. Is groundwater known to be contaminated by ☐onsite ☒ offsite ☐ both ☐ or unknown sources? Describe source(s): The locations of previous groundwater samples and a summary of previous groundwater data is provided in Attachment B. The chlorinated solvent tetrachloroethene (PCE) has been detected in low levels in site groundwater from a former off- 10 EMP Form ver.1, October 23, 2014 site upgradient drycleaner (American Dry Cleaning Company, DSCA ID 60-0002). The DEQ Drycleaning Solvent Cleanup Act (DSCA) program previously issued a no further action for the release incident. What is the direction of groundwater flow at the Brownfields Property? Groundwater flow is to the east and northeast (see Attachment B). Will groundwater likely be encountered during planned redevelopment activities? ☐ Yes ☒ No If yes, describe these activities: 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): Athough not anticpated 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). Note that in the unlikely event groundwater containing PCE from the adjacent drycleaner accumulates in an excavation and needs to be managed off-site, it will likely need to be managed as a listed hazardous waste in accordance with DSCA Program requirements. PART 3. SURFACE WATER – Please fill out the information below. Attach a map showing the location of surface water at the Brownfields Property. Is surface water at the property known to be contaminated: ☐ Yes ☒ No Will workers or the public be in contact with surface water during planned redevelopment activities? ☐ Yes ☒ No 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): If surface water run-off gathers in an open excavation during construction and the soil in the excavation is determined to be impacted, appropriate worker safety measures will be undertaken. 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). PART 4. SEDIMENT – Please fill out the information below. Is sediment at the property known to be contaminated: ☐ Yes ☒ No Will workers or the public be in contact with sediment during planned redevelopment activities? ☐ Yes ☒ No If yes, attach a map showing location of known contaminated sediment at the property. 11 EMP Form ver.1, October 23, 2014 In the event that contaminated sediment is encountered during redevelopment activities, list activities for management of such events (stream bed disturbance): PART 5. SOIL VAPOR – Please fill out the information below. Do concentrations of volatile organic compounds at the Brownfields property exceed the following vapor intrusion screening levels in the following media: IHSB Residential Screening Levels: Soil Vapor: ☒ Yes ☐ No ☐ Unknown Groundwater: ☐ Yes ☒ No ☐ Unknown IHSB Industrial/Commercial Screening Levels: Soil Vapor: ☐ Yes ☒ No ☐ Unknown Groundwater: ☐ Yes ☒ No ☐ Unknown Attach a map showing the location of soil vapor contaminants that exceed site screening levels. If applicable, at what depth(s) is soil vapor known to be contaminated? 7 ft Will workers encounter contaminated soil vapor during planned redevelopment activities? ☐ Yes ☒ No ☐ Unknown In the event that contaminated soil vapor is encountered during redevelopment activities (trenches, manways, basements or other subsurface work, list activities for management of such contact: No compounds were detected above non-residential vapor intrusion screening levels in previous soil vapor sampling. As such, it is unlikely that workers will encounter significantly contaminated soil vapor during redevelopment. Although not anticipated, in the event contaminated soil vapors are encountered during redevelopment activities, the area will be evacuated and appropriate safety screening of the vapors will be performed. If results indicate further action is warranted, appropriate engineering controls (such as use of industrial fans) will be implemented. PART 6. SUB-SLAB SOIL VAPOR -please fill out the information below if existing buildings or foundations will be retained in the redevelopment. Are sub-slab soil vapor data available for the Brownfields Property? ☐ Yes ☒ No ☐ Unknown If data indicate that sub-slab soil vapor concentrations exceed screening levels, attach a map showing the location of these exceedances. At what depth(s) is sub-slab soil vapor known to be contaminated? ☐ 0-6 inches ☐ Other, If other describe: Will workers encounter contaminated sub-slab soil vapor during planned redevelopment activities? ☐ Yes ☒ No ☐ Unknown 12 EMP Form ver.1, October 23, 2014 In the event that contaminated soil vapor is encountered during redevelopment activities, list activities for management of such contact: See above for soil vapor. PART 7. INDOOR AIR – Please fill out the information below . Are indoor air data available for the Brownfields Property? ☐ Yes ☒ No ☐ Unknown If yes, attach a map showing the location where indoor air contaminants exceed site screening levels. If the structures where indoor air has been documented to exceed risk-based screening levels will not be demolished as part of redevelopment activities, will workers encounter contaminated indoor air during planned redevelopment activities? ☐ Yes ☐ No ☐ Unknown In the event that contaminated indoor air is encountered during redevelopment activities, list activities for management of such contact: No structures are present at the site. Based upon the previous soil vapor sampling, DEQ concurred that indoor air risks were not significant for the proposed site buildings and vapor mitigation is not warranted for the proposed site buildings.

If a sub-grade feature or pit is encountered and does not require removal for geotechnical or construction purposes, it will be filled with soil or suitable fill and construction will proceed. Where appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation. If the pit has waste in it, the waste may be set aside in a secure area and will be sampled for waste disposal purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and disposed off-site at a permitted facility or the waste will be managed in accordance with Part 1 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. If buried piping is encountered and must be removed to allow development 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. In the event that impacts associated with an underground storage tank (UST) release are found to be present on the subject site, they will be addressed through the Brownfields Program. If buried materials or other waste materials which do not appear to be hazardous are identified at the site, then the material will be left in place unless it needs to be removed for geotechnical purposes. The locations of the materials will be documented in the final EMP Report. If the non-hazardous waste materials need to be removed, they will be disposed off-site. If buried materials appear to be hazardous (such as buried drums), then grading will stop and a plan for managing the materials will be developed for DEQ approval.
