and indeno(1,2,3‐cd)pyrene above their respective DEQ IHSB Residential PSRGs.   Dibenzo(a,h)anthracene was also detected in FCC‐1A at an estimated concentration above the  DEQ IHSB Residential PSRG.  No other SVOCs were detected above DEQ IHSB PSRGs in any other  samples collected at the Site.      Metals  Laboratory analytical results indicate that several metals were detected at concentrations above  the laboratory method detection limits.  The metal arsenic (up to 11.1 mg/kg) was detected in  multiple soil samples at concentrations above the DEQ IHSB Residential PSRG of 0.68 mg/kg  and/or Commercial/Industrial PSRG of 3.0 mg/kg.      Hexavalent chromium (up to 2.43 mg/kg) was detected at concentrations above the DEQ IHSB  Residential PSRG of 0.31 mg/kg in soil samples FCC‐1A, FCC‐1B, FCC‐2A, FCC‐4A, FCC‐4B, FCC‐5A,  FCC‐5B, FCC‐6, FCC‐7A, FCC‐8A, FCC‐8B, FCC‐9, B‐8, B‐9, and B‐10.  Selenium (up to 2.7 mg/kg)  was detected in samples FCC‐4A, B‐1*, B‐2*, and B‐3* at concentrations above the Residential  and/or Protection of Groundwater PSRGs.     Lead (703 mg/kg) and cadmium (4.6 mg/kg) were detected in soil sample FCC‐6 (4‐8) at  concentrations above the Protection of Groundwater and/or Residential PSRGs.  It is of note that  evaluation area FCC‐6 is an area proposed for placement of fill and is not planned for disturbance  during grading activities.      Additional metals, including barium, trivalent chromium, lead, mercury, and silver, were  detected in soil samples collected at the Site at concentrations below the DEQ IHSB PSRGs and  consistent with published background levels for North Carolina soils.      It is of note that metals concentrations detected in soil samples collected in areas of planned cut  appear to be generally consistent with naturally occurring levels with the exception of lead      10  EMP Version 2, January 2021   concentrations detected in FCC‐1A (114 mg/kg) and FCC‐2A (190 mg/kg).      2) Depth of known or suspected contaminants (feet):  As noted above, select VOCs, metals, and/or PAHs were detected at concentrations above the  DEQ IHSB PSRGs in composite soil samples FCC‐1A (3‐10 ft bgs), FCC‐1B (12‐16 ft bgs), FCC‐2A (5‐ 10 ft bgs), FCC‐7A (2‐4 ft bgs), and FCC‐8A (0‐5) and soil borings B‐2 (10 ft bgs), B‐8 (6 ft bgs), and  B‐9 (4 ft bgs).  In addition, select metals are present at levels above PSRGs in soil samples FCC‐4A  (4‐10 ft bgs), FCC‐4B (10‐14 ft bgs), FCC‐5A (5‐8 ft bgs), FCC‐5B (8‐13 ft bgs), FCC‐6 (4‐8 ft bgs),  FCC‐7A (2‐4 ft bgs), FCC‐8B (6‐8 ft bgs), B‐1* (8 ft bgs), B‐2* (8 ft bgs), B‐3* (8 ft bgs), and B‐10 (4  ft bgs).     As noted above, soil characterization area FCC‐6 is proposed for placement of fill.  Soil  characterization section FCC‐7 is also proposed for placement of fill with the exception of a small  area with higher elevations that will be leveled.  Soil in characterization sections FCC‐6 and FCC‐7  are planned to remain in place.      3) Area of soil disturbed by redevelopment (square feet):  Based on the preliminary grading plans and cut‐fill analysis (Appendix B), the majority of the Site  is expected to be cleared and graded (approximately 465,400 square feet) to level the Site for  redevelopment.  A copy of the preliminary grading plan and cut‐fill analysis is provided as  Appendix B.    4) Depths of soil to be excavated (feet):  Based on review of the cut‐fill analysis, planned cut depths are expected to range from 1 to 4 ft  bgs on the western Site parcel for installation of paved parking areas near the existing Site  building.  Review of the cut‐fill analysis prepared for the eastern Site parcels indicates that  planned cut depths are expected to range from approximately 1 to 18 ft bgs in the vicinity of the  proposed apartment buildings.  Other discrete areas may include deeper excavations for  installation of deeper foundational footers, elevator banks, utility banks, etc.  Remaining portions  of the Site are planned for fill to achieve final grade elevations.    5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):  Cut‐fill analysis and calculations indicate that the total volume of soil to be excavated and/or cut  from the eastern Site parcels is approximately 21,400 cubic yards.  The western portion of the  Site will require approximately 2,500 cubic yards to reach final grade elevations.  Soil generated  during grading on the eastern Site parcels will be used on‐Site as fill on the western Site parcel.    In addition to grading, limited excavations for installation of new utilities will be completed  during redevelopment of the Site.      6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:              Based on a review of the preliminary grading plan and results of in situ soil characterizations  assessment activities, approximately 18,000 cubic yards of excavated soil will contain      11  EMP Version 2, January 2021   compounds at concentrations above the DEQ IHSB PSRGs.    7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:    Based on review of the grading plan and cut‐fill analysis, up to 21,400 cubic yards of excess soil  may need to be transported off‐Site.  In‐situ soil sampling results identified PAHs at  concentrations above the DEQ IHSB Commercial/Industrial PSRGs in soil characterization areas  FCC‐1, FCC‐6, FCC‐7A, and FCC‐8A.  In‐situ soil sampling results identified PAHs at concentrations  above the DEQ IHSB Residential and/or Protection of Groundwater PSRGs in soil characterization  areas FCC‐2A and FCC‐7B.  Sampling results identified select metals at concentrations above the  DEQ IHSB Protection of Groundwater and/or Residential PSRGs but within naturally occurring  background concentrations in evaluation areas FCC‐4, FCC‐5, FCC‐8B, and FCC‐9.  No other  compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in  the case of metals in areas of planned cut that will generate excess soil.    If potentially impacted soil is encountered and cannot be reused on‐Site as fill, it will be sampled  and managed in accordance with the procedures described in the following sections.

greater than 100 mg/kg.  Partner requested that the lab analyze soil samples  FCC‐1A, FCC‐2, and FCC‐6 for TCLP lead.  Partner also requested that the lab  analyze soil samples FCC‐1A for TCLP chromium.  Results of analysis indicate that  chromium and lead were not detected at concentrations above the EPA  Maximum Allowable Concentrations of 5 mg/L in any of the soil samples.  Based  on results of soil assessment activities and TCLP lead and chromium analyses, no  compounds have been identified at characteristically hazardous levels.  In  addition, evaluation area FCC‐6 and FCC‐7 (aside from one area of higher  elevation) are proposed for placement of fill and soils in these areas are not  likely to be significantly disturbed during future grading.    Laboratory analytical results for soil samples FCC‐8B (6‐8’), B‐2 (10’), B‐3 (8’), B‐ 3* (8’), and B‐7 (13’) indicated the presence of total chromium at concentrations  above the TCLP criteria using the Rule of 20.      Deepest cut depths in soil characterization section FCC‐8 are expected to be  approximately 4 to 5 ft.  Therefore, deeper soil with total chromium  concentrations above 100 mg/kg within this section are not planned for  disturbance.  Soil samples B‐3, B‐3*, and B‐7 were collected in areas planned for  placement of fill and deeper soil with total chromium concentrations above 100  mg/kg in these areas are not planned for disturbance.             13  EMP Version 2, January 2021   d)

The VOCs acetone, 2‐butanone, chloromethane, ethylbenzene, 2‐hexanone, naphthalene,  toluene, and xylenes were detected in groundwater samples collected at the Site at  concentrations above the laboratory method detection limits, but well below the 2L Standards      24  EMP Version 2, January 2021   and the DEQ DWM Vapor Intrusion GWSLs.      Semi‐Volatile Organic Compounds  The SVOCs acenaphthene, benzyl alcohol, fluoranthene, fluorene, 1‐methylnaphthalene, 2‐ methylnaphthalene, naphthalene, phenanthrene, and pyrene were detected in groundwater  samples collected at the Site at concentrations above the laboratory method detection limits,  but well below the 2L Standards and the DEQ DWM Vapor Intrusion GWSLs.  No other organic  compounds were detected in Site groundwater at concentrations above the laboratory method  detection limits.    Metals  During assessment activities conducted in 2020 and 2021, groundwater sample results indicate  that total chromium (up to 58.0 µg/L) and lead (up to 18.3 µg/L) were detected in groundwater  at the Site at concentrations above the 2L Standards of 10 µg/L and 15 µg/L, respectively.   Groundwater analytical results also indicate that arsenic, barium, cadmium, and hexavalent  chromium were detected at concentrations above the laboratory method detection limits but  below the 2L Standards.      It is of note that the environmental reports prepared for the Site indicate high turbidity in the  groundwater samples collected at the Site and elevated metals concentrations may be attributed  to high turbidity.  Laboratory analytical results for filtered groundwater samples collected at the  Site in December 2020 did not detect dissolved concentrations of lead above the 2L Standards.     3) What is the direction of groundwater flow at the Brownfields Property?   Shallow groundwater is expected to mimic surface topography which slopes generally northwest  and northeast toward a tributary of Little Sugar Creek generally located along the northwestern  and northeastern Site boundaries (Figure 1).       4) Will groundwater likely be encountered during planned redevelopment activities?    ☐Yes    ☒No   If yes, describe these activities:  Shallow groundwater was encountered approximately 10 to 12 ft bgs during recent groundwater  assessment activities conducted in the western portions of the Brownfields property.  Grading  activities in the western portion of the Site are expected to result in a net import and will not  result in decreased surface elevations in areas where shallow groundwater may be encountered.   Proposed fill depths range from 1 to 3 ft.  The deepest trenches for utility installations are  proposed for 5 ft bgs following grading.  Therefore, encountering groundwater during  redevelopment activities is not anticipated at this time.    Shallow groundwater was encountered approximately 5 to 24 ft bgs during groundwater  assessment activities conducted in the eastern portions of the Brownfields property.  Shallow  groundwater may be encountered during grading and utility installation activities in this portion  of the Site.  If groundwater is encountered during redevelopment activities, the procedures  outlined below will be implemented.

the laboratory analytical results prior to removing the UST from the ground.  If a UST is encountered  that cannot be removed or does not require removal for geotechnical or construction purposes, it  may be abandoned in‐place with prior DEQ approval and construction will proceed.  Where  appropriate, the bottom may be penetrated before abandonment to prevent fluid accumulation.   Impacted soil in the vicinity of the UST will be managed in accordance with the Managing On‐Site  Soil section outlined above in the EMP.  DEQ UST Program protocol (or other protocol approved in  advance by the DEQ Brownfields Program) will be followed for UST abandonment procedures.      Sub‐Grade Feature/Pit:  If a sub‐grade feature or pit is encountered and does not require removal for geotechnical or  construction purposes, it will be filled with soil or suitable fill and construction will proceed.  Where  appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation.  If the  pit has waste in it, the waste will 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 the Managing On‐Site Soil section outlined  above in the EMP, 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.        32  EMP Version 2, January 2021     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:  If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to  stop work in that location and notify Hart & Hickman.  Hart & Hickman will screen materials using a  calibrated photoionization detector and Landtec GEM 5000® meter and collect samples, if  warranted.  In this event, confirmation sampling will be conducted at representative locations in the  base and the sidewalls of the excavation after the waste or significantly impacted soil is removed.   The confirmation samples will be analyzed for VOCs, SVOCs, and RCRA metals.  Areas of suspected  contaminated soil that remain at the Site after excavation is complete above applicable DEQ IHSB  Residential PSRGs will be managed pursuant to this plan.      If significant buried organic material or buried waste material that has the potential to produce  methane (i.e., wood, trash, etc.) is encountered during redevelopment activities, the Brownfields  program will be notified to discuss whether assessment for potential landfill gas accumulation is  warranted.      Re‐Use of Impacted Soils On‐Site:  Please refer to the description outlined in the Managing On‐Site Soil section (Part 1A) of the EMP  above.      If unknown, impacted soil is identified on‐site, management on‐site can be considered after the  project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields  Project Manager approval prior to final placement on‐site.     If other potential contingency plans are pertinent, please provide other details or scenarios as  needed below:
