PUBLIC NOTICE State of Tennessee Department of Environment and Conservation Division of Remediation Notice of an Approved Administrative Settlement Pursuant to 42 U.S.C. § 9613(f) Brownfield redevelopment of 1807 Cumberland Avenue Knoxville HUB Building 4 Site # 47-646 The Division of Remediation ("DoR") has accepted into its Brownfield Program an approximate 0.82-acre parcel of property located at 1807 Cumberland Avenue, Knoxville, which has been assigned Division site number 47- 646 and is commonly known as the Hub Knoxville Building 4 site to facilitate its redevelopment by Knoxville TN 1801 Cumberland Properties KP6, LLC (the "Voluntary Party"). The Brownfield Voluntary Agreement ("Agreement") between the Voluntary Party and DoR includes liability protection for the Voluntary Party and any successor parties, including protection against third-party contribution claims regarding matters identified and addressed in the Agreement. This notice serves the dual purpose of notice of the terms of the Agreement to the public and to third parties who may hold contribution claims under 42 U.S.C. § 9613 (f). The Site consists of a parcel located at 1807 Cumberland Avenue, Knoxville, which has been assigned Division site number 47- 646. The Site was historically used for residential purposes from at least 1917, followed by commercial use structures by at least the 1950s. An automobile (filling) station and multiple dry cleaners were historically located adjacent to or in the vicinity of the subject property. The Voluntary Party is the lessee of the Site and intends to use the Site for multifamily residential and limited commercial uses. Voluntary Party is constructing a new seven-story residence mixed-use building. The development will contain a total of approximately 212 apartments and approximately 803 beds located approximately two block(s) from the University of Tennessee campus in Knoxville, Tennessee. One Hundred Twenty (120) parking spaces and approximately 13,000 square feet of retail space will be located below the podium structure. Based on studies conducted by the Voluntary Party, arsenic was detected in soil samples above the EPA regional screening levels ("RSLs") for residential use, but below background levels. Soil gas samples detected benzene, bromodichloromethane, 1,3-butadiene and chloroform at levels that exceeded the Target Sub-Slab (residential) concentrations. Groundwater has not been sampled at the Site. The Site has been the subject of environmental investigations, the results of which have been reviewed by DoR. All reports of the investigation and remediation of the Site are on file with the DoR. These investigations concluded that the Site has been impacted by real or perceived hazardous substances, solid wastes or other pollutants determined to be present in this Site relating to the historical operations at the site. Due to the presence of these constituents, a Notice of Land Use Restrictions will be placed on the Site to limit future residential use of the Site, to require the design and installation of a vapor intrusion mitigation system, and to prevent accessing groundwater. A Soil and Groundwater Management Plan was prepared and will be followed during future development activities. These and other measures required by DoR under the Agreement for the Site will ensure protection of human health and the environment.
