With the exception of subsurface utility trenches, the soil beneath this building will not be excavated. It is anticipated that subsurface utility trenches will be located outside of areas of known contaminated soil beneath the Main Building. The area of petroleum‐impacted soil is adjacent to an aboveground storage tank in the Southeastern portion of the property. This area will not be disturbed during site redevelopment activities. If areas of known or suspected contaminated soil are discovered during the course of site redevelopment, then the Brownfields Program will be notified of the discovery within 48‐hours. 4) Depths of soil to be excavated (feet): 0‐2 feet (for exterior site grading and installation of subsurface utilities) 5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): The volume of soil excavated will be determined based on the need for site grading. A grading plan has not yet been prepared. The grading plan will be forwarded to NCDEQ once completed. All excess soil generated during grading will be relocated to other areas of the site. Soil excavated during subsurface utility construction will be placed back into the utility trenches and used as backfill (last out‐first in principal). Any excess soil will be sampled and temporarily containerized pending receipt of analytical data. 6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: None. It is anticipated that all subsurface utility construction and site grading will be performed outside of areas of known contamianted soil. 7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: None IMPORTED FILL SOIL 1) Will fill soil be imported to the site? ☐ Yes x No ☐ Unknown 2) If yes, what is the estimated volume of fill soil to be imported?

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? x Yes No If yes, explain why below, including the level of knowledge regarding processes generating the waste( include pertinent analytical results as needed). Trichloroethene has been detected in the soil beneath the Main Building structure. The site was originally utilized as a mobile home manufacturing facility, and later as a recycling facility. It is suspected that the presence of trichloroethene (and other chlorinated solvents) are related to site operations during the mobile home manufacturing operation. Based on the planned site redevelopment, areas of contaminated soil beneath the Main Building will not be disturbed. If yes, do the soils exceed the “Contained‐Out” levels in Attachment 1 of the North Carolina Contained‐In Policy? x 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 x No If yes, mark reason(s) why below (and include pertinent analytical results). ☐ Ignitability ☐ Corrosivity ☐ Reactivity ☐ Toxicity ☐ TCLP results 6 EMP Form ver.1, October 23, 2014 ☐ 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: The areas of soil impacted by a listed hazardous waste (specifically trichloroethene) are located beneath the Main Building structure on the property. The areas where TCE has been detected in the soil beneath the building will not be disturbed during site redevelopment activities. 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 Click here to enter a date. x Preliminary Health‐Based Industrial/Commercial SRGs 9/1/2015 ☐ Site‐specific risk‐based cleanup level, or acceptable concentrations determined via calculated cumulative risk.

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. x Transport and dispose of impacted soil offsite (documentation of final disposition must be sent to Brownfields Project Manager) x Landfill – analytical program determined by landfill x Landfarm or other treatment facility If impacted soil is encountered and requires disposal off‐site, the impacted soil will be properly sampled, containerized and transported to either a landfill (for non‐petroleum contamination) or to a NCDEQ‐permmitted landfarm (for petroleum contaminated soil). ☐ 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: Click here to enter text. MANAGEMENT OF UTILITY TRENCHES ☐ Install liner between native impacted soils and base of utility trench before filling with clean fill (Preferred) x 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. x 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: Subsurface utilities will be installed during site re‐development activities. It is anticipated that subsurface utilities will be situated outside of areas containing known or suspected impacted soil. Subsurface soils (especially inside the structures) will be evaulated for evidence of impact by regulated chemical constituents during the construction of subsurface utility trenches. Soil evaluation may be via field screening (using a PID or FID), collects of soil samples for laboratory analysis, or both. In all utility trenches (both inside and outside of the structures), the "last out‐first in" principle will be incorporated during trench backfilling. If soil evaluation activities indicate the subsurface utility trench is within an area of impacted soil, then a vapor barrier may be installed between the native soil and the utility piping prior 9 EMP Form ver.1, October 23, 2014 to backfill. This barrier may be constructed of polyethylene (>10 mil thickness) or a multi‐ply woven geotextile material. Additionally, all trenches located inside existing structures will be capped with concrete. PART 2.
