Known or suspected contaminants in soil (list general groups of contaminants):  H&H conducted Phase II Environmental Site Assessment (ESA) activities at the 530 E. Sugar Creek  Road parcel in November 2011 and conducted Brownfields assessment activities at the parcel in  October 2018.  Tabular summaries of the soil analytical data are provided in Appendix B.  Soil  sample locations are shown on Figure 3 and a brief summary of the results is provided below.    TPH‐DRO  The results of soil sample analyses indicate that detected concentrations of TPH‐DRO exceed the  North Carolina Action Level of 100 mg/kg in SB‐8 (0 to 2 ft), SB‐9 (6 to 8 ft), SB‐10 (0 to 2 ft), and  SB‐13 (3 to 4 ft).  These samples were collected in the vicinity of the former numerical control  lathes, the former RCRA room, the loading dock and former hazardous waste storage area, and  the former O&R room floor drain.  Sample were not collected for analysis of TPH‐DRO during the  October 2018 Brownfields assessment.    VOCs  Trichloroethylene (TCE) was detected above the Residential PSRG of 0.87 mg/kg in SB‐4 (0‐2 ft)  and above the Industrial/Commercial PSRG of 4.0 mg/kg in SB‐10 (6‐8 ft) during the November  2011 Phase II ESA.  These samples were collected in the vicinity of the former TCE degreaser and  the former loading dock and hazardous waste storage area.  No VOCs were detected above the  Residential or Industrial/Commercial PSRGs during the October 2018 Brownfields assessment.    SVOCs  SVOCs were not detected during the October 2018 Brownfields assessment at concentrations  above PSRGs.  SVOCs were not analyzed during the November 2011 Phase II ESA.    Metals  The results of the metals analyses indicate that concentrations of arsenic were detected above  laboratory reporting limits during the October 2018 Brownfields assessment in each soil sample  collected at concentrations ranging from 1.5 J mg/kg to 8.5 mg/kg and in the November 2011  Phase II ESA at concentrations between <0.58 to 4.7 mg/kg.  The arsenic concentrations are  generally within the range of Site‐specific background concentrations (3.1 mg/kg to 3.7 mg/kg)  collected in October 2018.  Arsenic was detected in two samples at concentrations above the  Site‐specific background range and the Industrial/ Commercial PSRG of 3 mg/kg, including: HHSB‐ 1 (8.5 mg/kg) and HHSB‐7 (5.7 mg/kg).        9  EMP Version 2, January 2021   Analytical results indicate that concentrations of hexavalent chromium were detected in 10 of  the 12 soil samples and each of the four background soil samples at concentrations ranging from  0.18 J mg/kg to 0.44 J mg/kg. Multiple soil samples contained hexavalent chromium detections at  concentrations above the Residential PSRG of 0.31 mg/kg but below the Industrial/Commercial  PSRG of 6.5 mg/kg during both the 2011 and 2018 assessments. The hexavalent chromium  detections were generally consistent in concentration and were collected from depths ranging  from 0 to 8 ft bgs from across the Site. No other metals were detected in the soil samples  collected at concentrations above background and PSRGs.        2) Depth of known or suspected contaminants (feet):  Sample depths are noted above and include depth ranges between 0 and 8 ft bgs.    3) Area of soil disturbed by redevelopment (square feet):  Approximately 196,020 square feet (4.5 acres; the entire 530 E. Sugar Creek Rd parcel) will be  disturbed during Site redevelopment.      4) Depths of soil to be excavated (feet):  To achieve the desired grade at the Site, soils will generally be imported to raise the existing  grade by up to 5 feet.  Because this is a net‐import site, significant excavation is not planned.    5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):  This is a net soil import site based on current grading plans and cut/fill analysis.  Limited  excavation activities could occur during initial scraping of surficial asphalt/gravel grading  activities.  If possible, these materials will be utilized on‐Site.      6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:              As noted above, limited excavation activities could occur during initial scraping of surficial  asphalt/gravel grading activities.  The scraping materials do not appear to be impacted based on  previous assessment activities.    7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:    Excavation of impacted soil is not anticipated.  Any soil excavated at the Site is proposed to be  re‐used in fill areas during redevelopment.        Part 1.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  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)

Soil export is not anticipated at this time.  Excavated soil is planned for use as fill material at the  Site.  However, if soil export is deemed necessary, in‐situ or stockpile sampling may be  performed.  The results of the export soil assessment will be presented to DEQ Brownfields  under separate cover if assessment activities are conducted.      In general, it is anticipated that export soil sampling will include laboratory analysis of VOCs by  EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Method 6020/7471, and  hexavalent chromium by EPA Method 7199.  It is anticipated that the composite samples will be  collected at a rate of approximately 1 sample per 1,000 cubic yards.   Sample volume for SVOCs  and metals analysis will be collected from up to 5 sample aliquot locations to form one (1)  composite sample.  Each aliquot will be field screened for the presence of VOCs using a  calibrated photoionization detector (PID).  VOC samples will be collected as grab from the aliquot  which exhibits the highest indication of impact during field screening.    Following completion of the soil sampling activities and receipt of the analytical data, H&H will  prepare a data summary package for DEQ review.  The data summary package will include a  tabular summary of the laboratory analytical results in comparison to the regulatory screening  levels and background metals concentrations, and a copy of the laboratory analytical report.   H&H assumes that the data summary package can be reviewed by DEQ to provide guidance  regarding potential export site selection.  Based on analytical results of soil samples collected  from the export soil, the soil will be transported off‐Site to a suitable location.  The PD will notify  DEQ Brownfields of the location receiving the export soil.  If not a permitted facility (e.g., another  Brownfields property), written approval from DEQ Brownfields and the receiving facility will be  obtained prior to transporting the soil off‐Site.  If the receiving facility is a non‐Brownfields  property, DEQ Solid Waste Section approval will be obtained prior to transporting the soil off‐ Site.    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)

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 Methods 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 & 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 7196 (assuming appropriate method detection  limits can be met by the laboratory) or 7199  Please provide details on the proposed methods of managing the following commonly  encountered issues during redevelopment of Brownfields Properties.  During construction activities, contractors may encounter unknown subsurface environmental  conditions (i.e., tanks, drums, or waste materials) that if encountered, will require proper  management.  Prior to beginning Site work, the project environmental professional will attend a  pre‐construction kick‐off meeting with the PD and the redevelopment contractors to discuss the  DEQ‐approved EMP and various scenarios when it would be appropriate and necessary to notify the  project environmental professional of the discovery of unknown subsurface features or potentially  impacted media at the Site.    In the event that such conditions are encountered during Site development activities, the      27  EMP Version 2, January 2021   environmental actions noted below will be used to direct actions to be taken during these activities  and sampling data for potentially impacted soil and the disposition of impacted soil will be provided  to DEQ when the data becomes available.    Underground Storage Tanks:   In the event a previously unidentified UST (orphan UST) or impacts suspected to be associated with  a previously removed UST are discovered at the Site during redevelopment activities, the orphan  UST removal and/or previously removed UST‐related impacts will be addressed through the DEQ  Brownfields Program.    If the orphan UST contains residual fluids, the fluids will be removed, sampled for VOCs, SVOCs, and  RCRA metals, and transported off‐Site for disposal at a suitable facility based on the laboratory  analytical results.  Impacted soil will be managed in accordance with Part 1.A. above and UST  removal will be addressed in coordination with the DEQ Brownfields Program.    Sub‐Grade Feature/Pit:  If a sub‐grade feature or pit is encountered during redevelopment, it will be removed in  coordination with the DEQ Brownfields Program.  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, SVOCs, and  metals and disposed off‐Site at a permitted facility or the waste will be managed in accordance with  Part 1.A. above, whichever is most applicable based on the type of waste present.  If the observed  waste characteristics indicate the concrete in the pit may potentially be contaminated to a  significant degree, the concrete will be sampled and analyzed by methods specified by the disposal  facility.    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 the environmental consultant.  The environmental consultant  will observe the suspect materials and collect samples if warranted.  In this event, confirmation  sampling will be conducted at representative locations in the base and the sidewalls of the  excavation after the waste or significantly impacted soil is removed.  The confirmation samples will  be analyzed for VOCs, SVOCs, and RCRA metals (or other analyses as appropriate based on the type  of waste material).  Information will be provided to DEQ Brownfields regarding the permitted  facility used for disposal of the waste or significantly impacted soil.  Areas of suspected  contaminated soil that remain at the Site after excavation is complete above the DEQ Residential  PSRGs will be managed pursuant to this plan.    Re‐Use of Impacted Soils On‐Site:  Please refer to the description outlined in Part 1.A. 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

BOLD indicates concentration exceeds the Residential PSRGs and background for metals Underline indicates concentration exceeds the Industrial/Commercial PSRGs and background for metals Soil concentrations are reported in milligrams per kilogram (mg/kg) Laboratory analytical methods are shown in parentheses VOCs = volatile organic compounds; SVOCs = semi-volatile organic compounds NA = not analyzed; NE = not established; ft bgs = feet below ground surface; -- = not applicable Aa = Final CCV recovery outside the control limits. The concentration reported may have a high bias. Ab = Initial CCV recovery outside the control limits. The concentration reported may have a high bias. Ac = Initial LLICV recovery outside the control limits. Result may have a low bias. B = Analyte is found in the associated blank. E = Estimated concentration above the calibration range. J = Detected above the laboratory method detection limit but below the laboratory reporting limit. Therefore, the concentration reported is an estimate.
