Title

SoCal Gas Line 80 Abandonment Demolition And Reclamation Plan

Description

PROJECT DESCRIPTION The project is for a Demolition and Reclamation Permit (DRP) to allow for the removal and abandonment of SoCal Gas Company’s Line 80. The portions of Line 80 that are proposed to be abandoned in place or removed are located adjacent to an existing bike path, east of Sandspit Road, extend south, under Tecolotito Creek/Goleta Slough, then west under Sandspit Road,traverse through the Goleta Beach County Park, westward, under SR 217, and terminate at an existing paved SoCalGas facility, east of Mesa Road. The project is made up of four segments along Line 80; Segments 1 and 3 include above and below ground pipeline removal and Segments 2 and 4 include below ground pipeline abandonment. Segment 1 includes above-ground removal of Line 80 and associated supports (approximately 23 supports) near the bank of Tecolito Creek (505 linear feet; support structure depth is approximately 7.0 feet), and removal and replacement of the existing Line 159 creosote-coated span support. The replacement support would extend less than two feet above the ground surface and would be drilled to a depth of 40 feet below ground approximately 10 feet from the creek bank. This replacement is required by the Code of Federal Regulation rule (49 CFR 92.161) issued by the U.S. Department of Transportation which states that each support or anchor on an exposed pipeline must be made of durable, noncombustible material. Segment 2 of pipeline runs under the Tecolotito Creek/Goleta Slough and State Route 217 (SR 217) and would be abandoned in place. After removing residual hydrocarbons and filling the pipe with 37 cubic feet of grout (130 linear feet; depth is approximately between 2.0 and 5.0 feet), plates would be placed over the open ends of the abandoned pipeline. Segment 3 will include excavation and removal of underground pipeline south of Tecolotito Creek/Goleta Slough, through Goleta Beach County Park, and up to the eastern boundary of the bike path parallel to SR 217 (1,565 linear feet; depth is approximately between 2.0 and 5.0 feet). Lastly, Segment 4 which runs to the eastern wall of an existing paved SoCalGas facility is proposed to be abandoned in place and filled with 322cubic feet of grout (1,141 linear feet; depth is approximately between 2.0 and 5.0 feet). In total, approximately 2,000 linear feet of pipeline is to be removed and approximately 1,300 linear feet of pipeline is proposedto be abandoned in place. Line 80 is within the unincorporated County coastal zone and within the Eastern Goleta Valley Community Plan (EGVCP) area. Segments 1 and 2 are in the California Coastal Commission (CCC) Permit Jurisdiction. Segments 3 and 4 are in the California Coastal Commission Appeal Jurisdiction. The portion of pipeline that is to be abandoned in place under SR 217 is under the City of Santa Barbara’s jurisdiction but administered by the CCC and Caltrans. Lastly, the terminus on UCSB is under University of California Regents/UCSB jurisdiction. The Coastal Commission and UCSB will process concurrent permit requests for those portions of the project within their respective jurisdictions. A total of 2.11 acres (91,900 square feet) of disturbance is proposed for the work areas and access routes/ramps. Grading will include approximately 2,768.5 cubic yards (CY) of cut and approximately 2,959.5 CY of fill. No trees are proposed for removal. The project will be served by the Goleta Water District and the Santa Barbara County Fire District. Access will be provided off of Sandspit Road and the Goleta Beach parking lot. The project spans over six APNs: 071-200-011, -008, -017, 071-210-001, 073-450-001, & 073-130-001, which cover 593.7-acres and are zoned REC, PU, & UCSB. The project site is primarily located southeast of California SR 217, east of the UCSB, and west of More Ranch Road in unincorporated Santa Barbara County in the Second Supervisorial District.
