May 18, 2021 - Present: The County Board of Supervisors approved Contract Amendment No. 1 to Contract No. BC19183 between the County and its Contractor WSP USA (formerly Ecology and Environment) for work not included in the original Agreement for Services to complete the Environmental Impact Report and Environmental Impact Statement for the proposed project. Upon issuance of funding from the Applicant, WSP USA will be issued a Notice to Proceed to complete the Draft EIR and EIS. The environmental documents are expected to be released to the public in the fall of 2021.


The Project would replace the existing, and currently emptied, purged, and idled, 123.4-mile pipeline system known as Lines 901 and 903. The replacement pipelines, herein after referred to as Lines 901R and 903R, would operate at a lower throughput capacity of 40,000 barrels per day and would include the following:

  • Line 901R - The installation, maintenance and operation of a twelve (12) inch diameter uninsulated steel pipeline, which is approximately 10.6 miles in length between the existing Las Flores Pump Station and the existing Gaviota Pump Station. The pipeline will increase to a sixteen (16) inch diameter steel pipeline for approximately 38.4 miles between the existing Gaviota Pump Station and the existing Sisquoc Pump Station.
  • Line 903R - The installation, maintenance and operation of a fourteen (14) inch diameter uninsulated steel pipeline for approximately 73.8-miles between the existing Sisquoc Pump Station and the existing Pentland Delivery Point.
  • The operation of fifty-one (51) total pipeline control valves (either motor operated valves or check valves). There are forty-one (41) standalone valve stations as well as ten (10) additional control valves located within pump station facilities.
  • Equipment modifications to (resizing of pumps, pig launchers/receivers, etc.) and continued operation of the Las Flores Pump Station, Gaviota Pump Station, and Pentland Delivery Point.
  • Equipment modifications, site expansion, and continued operation of the Sisquoc Pump Station. The site and facility expansion includes the development of a new 80,0000-barrel crude oil break-out tank, secondary containment area for the crude oil break-out tank, new foam storage tank, and installation of a foam fire suppression system.
  • The construction and operation of two new pump stations located at the Rancho Espanol and Russell Ranch properties in the Cuyama Valley region of San Luis Obispo County.
  • Various pipeline-related ancillary equipment including but not limited to: pipeline location markers, cathodic protection, fiber optic lines, supervisory control and data acquisition (SCADA) systems, remote communication equipment, emergency battery systems, diesel powered back-up generators, and/or solar panels.
