This will include eight tenant spaces totaling 18,496 square feet. Site plans for the proposed redevelopment are attached. On-site environmental concerns include the release of petroleum from the current Hasty Mart #23 gasoline station (North Carolina Division of Waste Management (NCDWM) UST Incident No. 38538). The UST system was owned and operated by the Wayne Oil Company. The most current site assessment information regarding the release of petroleum from the site is documented in the Limited Site Assessment (LSA) Report 3 EMP Form ver.1, October 23, 2014 (Phase I) report dated June 4, 2015 prepared by Terraquest. Terraquest also prepared a Site Check Report, dated December 30, 2014. Based on this information, NCDWM provided a Notice of No Further Action in a letter dated July 8, 2015. A Notice of Residual Petroleum (NRP) has been filed with the Register of Deeds noting that residual soil contamination is present at the site in excess of residential maximum soil contaminant concentrations (MSCCs) and residual groundwater contamination meets the cleanup requirements for a low-risk site but exceeds the North Carolina groundwater quality standards. The UST System will be closed by removal under NCDEQ UST Section regulatory requirements and guidance. This will include the removal of the five gasoline and diesel USTs that range in size from 3,000 to 4,000 gallons and associated distribution lines. Closure activities will also include the removal of three tanks on the property that were previously abandoned in-place and appear to be filled with concrete. During UST closure, we anticipate that up to 300 tons of residual petroleum impacted soil in close proximity to the USTs and distribution lines will be excavated and transported off-site to a permitted disposal facility (Soil Works in Zebulon, NC). The extent of excavation activities will be limited to soils disturbed during removal of the tanks and lines and in areas where the subsurface will be disturbed during future site redevelopment activities (i.e. foundation and subsurface utility installation). Soils below the estimated seasonally high water table, estimated to be at approximately four (4) feet below the current land surface, will not be excavated due to the presence of dry-cleaning solvent in groundwater from the nearby Penny Cleaners release (DSCA Site I.D. 96-0002, 433 N. Berkeley Boulevard). For the UST excavations, we estimate that approximately 400 pounds of OBC+ (a sodium persulfate and calcium peroxide mixture) will be mixed into soils with heavy equipment at the bottom of the excavation. The goal is to chemically oxidize and enhance the natural attenuation (degradation) of residual petroleum in soil and groundwater. This is a relatively low-cost solution to reduce the concentrations of residual petroleum and chlorinated solvent contamination beneath the site. Due to the presence of dry-cleaning solvent in groundwater, the water table will not be intersected during construction of the foundation system and installation of utilities. Building footings and utilites will be installed above the water table. No dewatering is planned. As a proactive measure, a vapor intrusion mitigation system consisting of a VaporBlock Plus 20 barrier and passive vent system will be installed under the entire footprint of the building to mitigate potential vapor intrusion risk from petroleum and dry-cleaning solvent in groundwater. 3) 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. 4) Schedule for Redevelopment (attach construction schedule): a) Phase I start date and anticipated duration (specify activities during each phase): 4/18/2016 4 EMP Form ver.1, October 23, 2014 Begin UST closure activities. b) If applicable, Phase 2 start date and anticipated duration (specify activities during each phase): 4/25/2016 Start of foundation and utility installation and grading. c) Additional phases planned?
