☒  Other, specify: self‐storage facility, offices, and retail tenants  2)  Summary of Redevelopment Plans (attach conceptual or detailed plans as available): The PD plans  to renovate the existing site building for use as a self‐storage facility, commercial offices, and retail  tenant space.  A Construction Plan (Figure A‐111) is provided in Appendix A.  3)  Do plans include demolition of structure(s)?:  ☐  Yes ☒ No ☐ Unknown  a)  Do plans include removal of building foundation slab(s) or pavement:    ☐   Yes ☒  No ☐  Unknown  b) Provide brief summary of redevelopment plans, including demolition, removal of building  slabs/pavement and other structures:      Proposed redevelopment activities include shallow excavations for installation of sidewalks, footings,  and depressed curbs planned for areas along the western and southern sides of the existing site  building.  Locations and depths of the proposed shallow excavations are depicted on the Construction  Plan (Figure A‐111) included in Appendix A.  Renovations to the interior of the existing site building  will also occur.      3  The site was operated as a manufacturer of dental equipment by Pelton & Crane Company from  approximately 1955 to 1992.  In the late 1990s and early 2000s, soil, groundwater, soil gas, indoor air,  and sediment/surface water impacts were detected at the site and the site was listed on the North  Carolina Inactive Hazardous Sites list (Pelton & Crane Site, NCD055162069).  Metals, volatile organic  compounds (VOCs), and polynuclear aromatic hydrocarbons (PAHs) have been detected in site soil at  concentrations exceeding regulatory screening levels.  Assessment and remediation at the site are  being conducted in accordance with an Administrative Agreement for Registered Environmental  Consultant (REC) Directed Assessment and Remedial Action between Siemens and the North Carolina  Department of Environmental Quality (DEQ).  Previous remedial activities performed at the site have  included soil excavation and off‐site disposal and groundwater remedial injections.       Portions of the proposed shallow construction excavation along the western side of the site building  will be within the extent of a previously excavated area near the former western baghouse,  wastewater treatment area, and original plating Area 1.  Approximately 3,500 tons of impacted soil  were removed from this area during Phase I Remedial Action activities conducted in 2006.  Depths of  the 2006 excavation ranged from approximately 18 inches to 72 inches below the ground surface.   Results of confirmation soil samples collected from the base and sidewalls of the excavation indicated  that compound concentrations were below the site specific protection of groundwater remedial goals  and/or background concentrations.  The excavation area was backfilled with imported clean soil upon  completion of the remedial action.  Therefore, the proposed shallow construction excavation along  the western side of the building will primarily be in clean backfill soils in areas previously remediated.   Details associated with the 2006 remedial action activities conducted in the vicinity of the western  side of the building are documented in the Second Quarter 2006 Remedial Action Quarterly Progress  Report prepared by Advanced Geoservices Corporation dated October 6, 2006.    Several existing groundwater monitor wells are located in the vicinity of the proposed shallow  excavation areas.  The general contractor conducting site work will identify the locations of  monitoring wells in the vicinity of the proposed excavation areas and demark the wells with traffic  barrels and flagging.  To minimize the potential for damaging or destroying the existing site monitor  wells, the PD modified the construction plans for the sidewalks, footers, and depressed curbs to be in  compliance with the Media Disturbance requirements stipulated in the Siemens Access and Indemnity  Agreement and Temporary Use Restriction document.  Site work and associated excavations will be  at least 5 feet from existing monitoring wells (see Figure A‐111 attached).    4)  Which category of risk‐based screening level is used or is anticipated to be specified in the  Brownfields Agreement?  ☐ Residential ☒ Non‐residential or Industrial/Commercial    Note: If children frequent the property, residential screening levels shall be cited in the Brownfields  Agreement for comparison purposes.     5)  Schedule for Redevelopment (attach construction schedule):    a) Phase I start date and anticipated duration (specify activities during each phase):    Interior Renovations:  Beginning 6/13/2016 ‐ TBD  Shallow excavation site work:  6/27/2016 – 7/12/2016  b) If applicable, Phase 2 start date and anticipated duration (specify activities during each  phase):   NA  4  c) Additional phases planned?  If yes, specify activities if known:  Yes    ☐    No ☒      Not in the foreseeable future   ☐     Decision pending☐   d) Provide the planned date of occupancy for new buildings: TBD    CONTAMINATED MEDIA    Contaminated Media (attach tabulated data summaries for each impacted media and figure(s) with  sample locations):  Tabulated data tables and figures pertinent to the proposed construction activities  are provided in Appendix B.    Part 1. Soil:

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.    1) Known or suspected contaminants in soil (list specific compounds):   A Construction Plan (A‐111)  depicting the locations of proposed shallow excavation areas is included in Appendix A.  Tabulated  summary of pertinent soil sample data from previous reports and maps depicting the soil sample  locations are provided in Appendix B.  Historically, metals, PAHs, and chlorinated solvent compounds  have been detected at concentrations exceeding regulatory screening criteria in proposed excavation  areas located west of the site building.  However, soil in this area was excavated and disposed of off‐ site as part of 2006 remedial action activities.  Post excavation confirmation soil samples indicate that  concentrations of compounds of concern were below site specific protection of groundwater  remediation goals and/or established site‐specific background concentrations.  The excavation basins  were subsequently backfilled with imported clean soils.  Limited soil assessment activities have been  conducted on the south side of the site building where additional proposed shallow excavations are  planned for installation of new footers and depressed curbs.  However, the area south of the facility  has historically been utilized for parking and it does not appear that manufacturing activities occurred  on this portion of the site.    2) Depth of known or suspected contaminants (feet):     As discussed above, impacted soils were excavated from depths ranging from 18 to 72 inches below  the ground surface along the western side of the site building.  Analytical results of post excavation  soil samples collected from the base and sidewalls of the excavation did not indicate that impacts  remained at levels exceeding the site specific remediation goals and/or established site‐specific  5  background concentrations.  Proposed excavation depths on the western side of the facility range  from approximately 1 ft to 3 ft below the current grade.  The proposed excavation depths in this area  of the site are not expected to exceed the base of the 2006 excavation.    3) Area of soil disturbed by redevelopment (square feet):   Approximately 1,100 sq ft (see Construction  Plan in Appendix A).    4) Depths of soil to be excavated (feet):  Excavation depths for the sidewalk proposed for the western  side of the Site building and the depressed curbs proposed south of the building are anticipated to be  approximately 4 inches to 12 inches below grade.  Excavation depths for ramp footings proposed for  the western side of the building and column footings proposed for the southeastern corner of the site  building are anticipated to be approximately 3 ft below grade.      5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):    A Construction Plan  is included in Appendix A.  Approximately 45 to 50 cubic yards of soil will be disturbed during the  proposed shallow excavation activities.    6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:  The  majority of the proposed excavation activities will be conducted in an area west of the Site building  where previous excavation activities were performed to remediate impacted soils.  The excavation  was backfilled with clean imported soils.  As such, it is anticipated that the excavation extents  proposed here will be predominantly conducted in clean backfill material and no contact with  impacted soil is anticipated.  However, the general contractor will perform excavations in accordance  with the Media Disturbance terms outlined in the Access and Indemnity Agreement and Temporary  Use Restriction document including oversight by Hart & Hickman personnel.      7) Estimated volume of contaminated soil expected to be disposed offsite, if applicable: Disposal of  impacted soils at off‐site locations is not anticipated at this time.  If off‐site impacted soil disposal is  warranted, then it will be conducted in accordance with the procedures identified below.      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?  Unknown at this time.    3) If yes, what is the depth of fill soil to be used at the property?  Unknown at this time.         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), or attach existing data:   If needed, imported fill soil will  be analyzed for the following constituents:     ☒   Volatile organic compounds (VOCs) by EPA Method 8260   ☒  Semi‐volatile organic compounds (SVOCs) by EPA Method 8270  6  ☐   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 and Analytical Method:         ☐ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE):  If fill soil is  obtained from a portion of an off‐site property that has not been previously developed (i.e., virgin land),  DEQ will be contacted to discuss sampling protocol based on estimated volume of import soil.  At least  one soil sample will be collected from the borrow source prior to the soil being transported to the site.  The soil sample will be analyzed for VOCs, SVOCs, and Priority Pollutant List metals plus hexavalent  chromium.  Soil will be considered suitable for use at the site if it does not contain compound  concentrations above DEQ IHSB Residential PSRGs or typical background levels for metals.  If fill soil is  obtained from a portion of an off‐site property that has been previously developed, then soil samples will  be collected at a rate of approximately one soil sample per 400 cubic yards.  The soil sample will be  analyzed for VOCs, SVOCs, and Priority Pollutant List metals plus hexavalent chromium.  Soil will be  considered suitable for use at the site if it does not contain compound concentrations above DEQ IHSB  Residential PSRGs or typical background levels for metals.      MANAGING ON‐SITE 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 and volumes are acceptable, if only preliminary data  available).   A Construction Plan is included in Appendix A.  Soil excavated at the site will be used as  backfill under the proposed ramp located along the western side of the building.  Per the terms  stipulated in Access and Indemnity Agreement and Temporary Use Restriction, Section(viii),  construction in excavation areas will be completed and/or the excavation basin will be closed within  30 days of soil extraction.    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).           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  7  BE RE‐USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH NCDEQ 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).  If no, explain rationale:  Historical analytical results from the site did identify soil that was considered to be a characteristic  hazardous waste.  However, the characteristically hazardous soil was removed from the site and analytical  results of post excavation confirmation soil samples indicate that concentrations are well below  hazardous levels.  Furthermore, the soils that were identified as characteristically hazardous, were located  beneath the site building.  No media disturbance activities are planned beneath the site building.    ☐ 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)    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 on‐site location and capped, removed offsite):  ☐  Preliminary Health‐Based Residential SRGs         ☒  Preliminary Health‐Based Industrial/Commercial SRGs   April 2016  ☐   Site‐specific risk‐based cleanup level, or acceptable concentrations determined via  calculated cumulative risk. Enter details of methods used for determination/explanation:             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:  Significant areas of contaminated soil are not  expected to be encountered or disturbed during site redevelopment activities based upon previous soil  sampling data and the Construction Plan.  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.   Soil piles will be covered with plastic sheeting when not in use (and overnight) to control dust levels and  stormwater erosion.  In the unlikely event that potentially impacted 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 activities at the site, the  workers, contractors, and environmental consultant will observe soils for evidence of potential  significantly impacted soil that may not be suitable to leave in place in exposed areas at a commercial use  8  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, 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 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 anticipate collecting additional soil samples based on previous site assessment activities.  If  significant impacted soil 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.  Per the term stipulated in Access and

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.      Check the following activities that will be conducted prior to commencing earth‐moving activities at  the site:  ☐ Review of historic maps (Sanborn Maps, facility maps)  ☐ Conduct geophysical surveys to evaluate the location of suspect UST, fuel lines, utility lines, etc.  ☐ Interviews with employees/former employees/facility managers/neighbors  Appendix B Analytical
