4 Environmental Analysis <br /> 4.5 Cultural Resources <br /> entirety of the gen-tie corridors. No archaeological resources were identified. One previously <br /> recorded transmission line (P-39-005337) and three newly documented transmission lines were <br /> documented crossing the gen-tie corridor (the Tesla-Los Banos 500-kV Transmission Line, the <br /> Tesla-Metcalf 230-kV Transmission Line, and the Tesla-Metcalf 500-kV Transmission Line). <br /> Built Environment Resources within the Project Site <br /> Tesla-Salado-Manteca 115kV Transmission Line ca. 1966 (P-39-005337). The entire resource <br /> was previously recorded by Cardno, Inc., in 2017 and was recommended not eligible for listing to <br /> the CRHR. The record for P-39-00537 was updated as part of this current 2022 assessment. No <br /> changes were observed, and Price et al. (2022) concurred with the previous assessment of <br /> resource P-39-005337 as not eligible for listing in the CRHR. <br /> Tesla-Los Banos 500-kV Transmission Line (TLBTL). TLBTL is an electrical transmission line that <br /> was newly identified as part of this assessment. The linear resource was first identified during a <br /> review of historic imagery prior to the field effort and was formally recorded during the pedestrian <br /> survey. Research determined that TLBTL was constructed ca. 1966. The TLBTL is 57 miles long <br /> and consists of two parallel, single-circuit, 500-kV electrical transmission lines connected to a <br /> series of steel lattice towers. A small segment that is within the proposed transmission line area <br /> contain wires that connect to adjacent towers. No major changes have occurred to the towers <br /> since their original construction. This resource is recommended not eligible for listing in the <br /> CRHR. <br /> Tesla-Metcalf 230-kV Transmission Line (TM230TL). TM230TL is an electrical transmission line <br /> that was newly identified as part of this assessment. It consists of a double-circuit 230-kV electrical <br /> transmission line connected to a series of steel lattice towers. The towers have concrete footprints <br /> and a tapered form with three sets of cross-arms located at the top. The line was reconfigured to <br /> extend north-south (parallel to Midway Road) due to expansion of Tesla Substation in the 1960s. <br /> This segment of the larger transmission line was recommended not eligible for listing in the CRHR. <br /> Tesla-Metcalf 500-kV Transmission Line (TM50OTL). TM50OTL is an electrical transmission line <br /> that was newly identified as part of this assessment. The linear resource was first identified during <br /> a review of historic imagery prior to the field effort and was formally recorded during the pedestrian <br /> survey. Research determined that the TM50OTL was first constructed ca.1949 and later <br /> reconfigured ca. 1959. The TM50OTL is approximately 35 miles long and consists of a double- <br /> circuit, 500-kV, electrical transmission line connected to a series of steel lattice towers. The <br /> segment within the proposed transmission line area contains wires that connect to two towers <br /> (adjacent) and was reconfigured to extend north-south due to the expansion of the Tesla <br /> Substation in the 1960s. This segment of the larger transmission line was recommended not <br /> eligible for listing in the CRHR. <br /> Built Environment Resources Adiacent to the Project Site <br /> Two historic resources were identified on land directly adjacent to the 106-acre land parcel portion <br /> of the Project site: previously recorded site P-01-10500 (Haera-Brockman-Griffith Ranch) and a <br /> historic transmission line. <br /> Griffith Energy Storage Project 4.5-15 Tetra Tech/SCH 2022120675 <br /> Draft Environmental Impact Report August 2023 <br />
