  • Templeton Substation Expansion Alternative PRTR
    Estrella Substation and Paso Robles Area Reinforcement Project Paleontological Resources Technical Report for Templeton Substation Alternative San Luis Obispo County, California Prepared for NextEra Energy Transmission, West LLC 700 Universe Boulevard Juno Beach, Florida 33408 Attn: Andy Flajole Prepared by SWCA Environmental Consultants 60 Stone Pine Road, Suite 100 Half Moon Bay, California 94019 (650) 440-4160 www.swca.com June 2019 Estrella Substation and Paso Robles Paleontological Resources Technical Report for Area Reinforcement Project Templeton Substation Alternative EXECUTIVE SUMMARY A Paleontological Resources Technical Report (PRTR) has been prepared for the Templeton Substation Alternative, which is an alternative substation location to the site proposed by NextEra Energy Transmission West, LLC (NEET West) in its Proponent’s Environmental Assessment (PEA) (May 2017) for the Estrella Substation and Paso Robles Area Reinforcement Project (project). Pacific Gas and Electric Company (PG&E) and NEET West prepared and filed a PEA with the California Public Utilities Commission (CPUC) in May 2017 for the project. The CPUC issued a PEA deficiency letter (Deficiency Letter No. 4, dated February 27, 2018) requiring that PG&E and NEET West evaluate additional alternatives to the proposed project, including the Templeton Substation Alternative. This PRTR provides a technical environmental analysis of paleontological resources associated with the substation alternative. The Templeton Substation Alternative (herein referred to as the “substation alternative”) is located in unincorporated San Luis Obispo County, adjacent to the existing PG&E Templeton Substation, approximately 1.5 miles northeast of the community of Templeton. The substation alternative will be comprised of two separate and distinct substations on an approximately 13-acre site.

  • B118 Basin Boundary Description 2003
    Hydrologic Region Central Coast California’s Groundwater Carrizo Plain Groundwater Basin Bulletin 118 Carrizo Plain Groundwater Basin • Groundwater Basin Number: 3-19 • County: San Luis Obispo • Surface Area: 173,00 acres (270 square miles) Basin Boundaries and Hydrology The Carrizo Plain Groundwater Basin underlies a narrow northwest trending valley that lies between the Temblor Range on the east and the Caliente Range and San Juan Hills on the west. The valley has internal drainage to Soda Lake. The San Andreas fault zone passes through the valley. Average annual precipitation ranges from 7 to 9 inches. Hydrogeologic Information Water Bearing Formations Groundwater is found in alluvium and the Paso Robles and Morales Formations. Alluvium. Upper Pleistocene to Holocene alluvium consists of unconsolidated to loosely consolidated sands, gravels, and silts with a few beds of compacted clays. Paso Robles Formation. The Pleistocene age Paso Robles Formation consists of poorly sorted, mostly loosely consolidated gravels, sands, and silts. The combined thickness of these deposits is more than 3,000 feet in the eastern portion of the basin along the San Andreas fault and decreases toward the west. Morales Formation. The Upper Pliocene Morales Formation consists of sands, gravels, and silts, which generally are more stratified and compacted than in the overlying Paso Robles Formation. Recharge Areas Recharge to the basin is largely by percolation of stream flow and infiltration of rainfall to the valley floor (DWR 1958). Groundwater Level Trends No information is available. Groundwater Storage Groundwater Storage Capacity. The total storage capacity is estimated at 400,000 af (DWR 1975) Groundwater in Storage.

Sgarro (PPL Bell Bend, LLC) to U.S. NRC, "BBNPP Plot Plan Change Supplement Schedule Update," dated September 28, 2010 In Reference 1, PPL Bell Bend, LLC (PPL) provided the NRC with schedule information related to the intended revision of the Bell Bend Nuclear Power Plant (BBNPP) footprint within the existing project boundary which has been characterized as the Plot Plan Change (PPC). As the NRC staff is aware, the plant footprint relocation will result in changes to the Combined License Application (COLA) and potentially to new and previously responded to Requests for Additional Information (RAIs). PPL declassified this docketed schedule information from regulatory commitment status in Reference 2, with an agreement to update the staff via weekly teleconferences as the project moves forward. PPL has committed to provide the NRC with COLA supplements, consisting of revised COLA Sections and associated RAI responses/revisions, as they are developed. These COLA supplements will only include the changes related to that particular section of the COLA and will not include all conforming COLA changes.
