The fill material will be sampled at the borrow pit to ensure that no contamination is present. 3) If yes, what is the depth of fill soil to be used at the property? The depth of the fill soil will be the floor of the basement at 320 E. Franklin Street which is estimated at a depth of 10 feet below grade level. 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) 5 EMP Form ver.1, October 23, 2014 ☒ Other Constituents & Analytical Method: Chromium (Tri & Hex) ☒ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE): The source of the borrow material will be determined by the chosen demolition contractor.

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: The known concentration of TCE does not exceed the NCDEQ’s Unrestricted Use Health Based PSRG.

Significant areas of contaminated soil are not expected to be encountered or disturbed during future Site redevelopment activities based upon previous Phase I Assessment. The demolition contractor will take into account conditions such as wind speed, wind direction, to minimize dust generation. 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 as needed based on Site and atmospheric conditions (i.e. by controlled water application, hydro-seeding, and/or mulch, stone, or plastic cover). Potentially impacted soil will be managed as described below. ☐ Field Screening: ☐ Yes ☒ No If yes, describe method; If no, explain rationale: All excavated soils will be stockpiled and sampled. During soil disturbance at the Brownfields Property, the workers or contractors will observe soils for evidence of potential significantly impacted soil that may not be suitable to leave in place in exposed areas at an industrial/commercial use Site. Evidence of potential significant impacted soil includes a distinct unnatural color, staining, strong odor, or 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 engineer to observe the suspect condition. If the project environmental engineer confirms that the material may be impacted, the environmental engineer will contact the DEQ Brownfields project manager within two business days 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: All excavated soils, if any, will be stockpiled and sampled prior to reuse or disposal. ☒ 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.
