Introduction: The Brownfields Property is comprised of one parcel that totals 11.7 acres and bears Tax Identification Number 452513047216. The Brownfields Property is owned by McConnell Holdings, Inc. which wants to donate the property to the City of Kinston, who is the Prospective Developer (PD). The Brownfields Property was operated as a cotton/spinning mill from 1914 until 2002 by at least two operators. Currently, the main mill building is vacant and in disrepair, but the warehouse on-site is used by National Spinning Company for the blending and bailing of raw yarn. Redevelopment Plans: The Prospective Developer (PD), the City of Kinston would like to market the Brownfields Property for redevelopment; however, an interested developer has not yet been identified. Previous discussions have centered on a mixed use of retail, commercial, office, restaurant and residential. Site History: The Brownfields Property was used as a cotton/spinning mill since at least 1914 until approximately 2003 and was occupied by Caswell Cotton Mills from 1914 through 1936; by an unknown entity from 1936 to 1948; and by Glen Raven Cotton Mills, Plant Number 2 from 1948 through 2003. By 2013 the National Spinning Company occupied at least a portion of the Brownfields Property and still is operating at the site. Prior to 1978 certain portions of the site were used for residential purposes. National Spinning Company granted the property to the current owner, McConnell Holdings, Inc. in 2005. Three building structures were identified in historical Sanborn Maps dated 1914 illustrating a similar building orientation as that currently observed. Sanborn Maps dated 1958, 1948, 1930, and 1925 were reviewed and the labels and descriptors identified on the maps were used to determine the use of the property and associated structures. The Glen_Raven_Decision Memo 2 western most building (Building 1) is labeled cotton warehouse. The small square building (Building 2) is labeled as an office. The large southernmost building (Building 3) is the main mill building and is labeled on Sanborn Maps as winding and spinning on the first floor and drawing, carding, slubbers, and speeders on the second floor. The southwest portion of Building 3 is labeled as the location for the engine room, boiler room, and machine shop. Adjacent to the boiler room, outside of building 3 is an area labeled coal pile and west of the coal pile (across the railroad trestle) is a small structure labeled waste house. Additionally, an oil house is visible south of Building 3. Information from the afore mentioned Sanborn Maps indicate the site was steam powered and fueled with coal. In 2015 the western building (Building 1) was still utilized for blending and bailing raw yarn by the National Spinning Company. The other two buildings were unoccupied. Sources of contamination at the Brownfields Property were due to the use of petroleum products for fuel and maintenance purposes inside the buildings, and the storage of coal in the southwestern portion of the property. Oil staining was noted around equipment in the main mill building (Building 3) on the first floor and the concrete basement floor. Several drums and/or barrels labeled used oil, lubing oil, and dye barrels near these areas in Building 3. Additionally, several barrels in the room located east of the furnaces in Building 3 had deteriorated and were leaking onto the concrete floor. A total of ten 55- gallon drums were removed from the site, including two drums that were leaking. The property is being assessed under an EPA brownfields assessment grant, the grant period for which terminates on September 30, 2017. The property to the immediate west of the site, which is owned by the City of Kinston and used as a storage yard and former power plant was subject to petroleum hydrocarbon contamination from above ground and underground storage tanks (ASTs and USTs). Reportedly the site underwent remediation with respect to petroleum hydrocarbon impacts to soil and groundwater under the UST Section, and the site was closed in 2000. Two public water supply wells are located on this property. Potential Receptors: Potential receptors are users of the two public water supply wells located immediately to the west of the Brownfields property, construction workers, future onsite workers, future residents, visitors, and trespassers. Contaminated Media Summary: DEQ has evaluated data collected from the following media at the subject property: soil groundwater and sub-slab soil gas. Only soil samples showed exceedances of the Inactive Hazardous Site Branch Preliminary Residential Health Based Soil Remediation goals (PSRG) (October 2016 version). DEQ relies on the following data to base its conclusions regarding the subject property and its suitability for its intended reuse. Soil Glen_Raven_Decision Memo 3 An area of soil impacted by several polynuclear aromatic hydrocarbons (PAHs) benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene, naphthalene and arsenic is documented. benzo(a)pyrene was detected at 1.2 mg/kg in sample SB-4, benzo(a)anthracene was detected at 2.0 mg/kg in sample SB-5, benzo(b)fluoranthene was detected at 2.2 mg/kg in sample SB-5, naphthalene was detected at 6.1 mg/kg in sample SB-5, and arsenic was detected at 24 mg/kg in sample SB-5. These data were compared against the following PSRGs for benzo(a)pyrene, which is 0.016 mg/kg, benzo(a)anthracene, which is 0.16 mg/kg, benzo(b)fluoranthene, which is 0.16 mg/kg, naphthalene, which is 3.8 mg/kg, and arsenic, which is 0.68 mg/kg. Risk Calculations Risk calculations were performed using North Carolina Department of Environmental Quality Risk Calculator, August 2016 Version. The risk calculations indicate the following: Table above shows that there are no risk exceedances. There is neither Carcinogenic Risk nor Hazardous Index that exceeded acceptable residential risk levels. Required Land Use Restrictions – Land use restrictions will include the standard land use, Environmental Management Plan and reporting, groundwater, soil disturbance, access, known contaminants, and LURU reporting LURs. Based on the site-specific data provided to the Brownfield program, the site reuse is suitable for the site if the agreed upon land use restrictions in the BFA are abided by.
