Sacate Canyon pipeline removal

San Augustine pipe stanchion removal

What's New

  • Pipeline removal at the Hollister Ranch site has been completed and restoration and revegetation monitoring continues to ensure compliance with the project conditions of approval.


A seven mile long onshore pipeline corrodor that once supported three pipelines.  Sections of the pipelines were either removed or abandoned in place depending upon location or resource constraints, such as sensitive creek habitats. 


The Texaco's Hollister Ranch Pipeline corridor is located between the Santa Ynez Mountains and the Pacific Ocean. The approximately seven-mile-long corridor is located between San Augustine Canyon and Gaviota State Beach. This corridor crosses two major land holdings; Hollister Ranch and Gaviota State Park.

Onshore Facilities

  • There are a total of three pipelines in the Texaco-Hollister Ranch pipeline corridor. These include one 8-inch, one 6-inch and one 2.5-inch pipeline.
  • The 2.5-inch pipeline runs along only a portion of the corridor, approximately two miles to a pig receiver at Alegria Creek. The 8-inch and 6-inch pipelines runs seven miles.
  • Texaco proposes to remove approximately one-half mile of pipelines at 38 different locations as well as above-ground lines, supports and footings at a number of creeks and abandon the remaining 6.5 miles of pipelines in place.

Past Activities

  • Pipelines were installed during 1960 and used to support development of the Conception and Cuarta offshore oil and gas fields (State lease 2725 and 2206), transporting oil and gas from two offshore platforms (Helen & Herman) to the Texaco Gaviota Oil and Gas Processing Plant.
  • The pipelines extended 8.6 miles from the oil and gas facility, west through Gaviota State Park and the Hollister Ranch, to San Augustine Point where they extended offshore to the platforms.
  • The pipelines, platforms and oil and gas processing facility were used for oil and gas production from 1962 until 1973.
  • During 1973 the offshore wells were shut-in, the pipelines were flushed and the facility was idled.
  • In 1988 the platforms and offshore pipelines were removed.
  • In 1998, the Texaco Gaviota Oil and Gas Processing Plant was removed.
  • A portion of the onshore pipelines (1.6 miles) was abandoned as part of the removal of Texaco's Gaviota Oil and Gas Processing Plant. The remaining portion of the pipelines (7 miles) was left in place to be abandoned at a later date.
  • The County received an application in 1998 to abandon the seven mile section of pipelines running through the Gaviota State Park and the Hollister Ranch.
  • Texaco proposed to remove approximately one-half mile of pipelines at 38 different locations as well as above-ground lines, supports and footings at a number of creeks and abandon the remaining 6.5 miles of pipelines in place.
  • The County prepared an Environmental Impact Report (EIR) to evaluate the potential impacts of the abandonment project.
  • Removing the pipelines below the creeks and the pipeline support footings was proposed by the County and evaluated in the EIR as a project alternative to mitigate potential significant biological and geological impacts should the pipelines become exposed in the future.
  • The EIR identified an Environmentally Superior Alternative (ESA) that is a hybrid of the proposed and alternative projects. The ESA recommends that all pipelines exposed above creeks and ravines be removed, as well as all pipeline supports and all but a few footings.
  • Only the pipelines that run beneath Agua Creek were recommended for removal.
  • The project was approved by the Planning Commission on January 23, 2002, and appealed by the Hollister Ranch Owners Association (HROA) on February 4, 2002. On May 8, 2002, the HROA dropped its appeal, and the issues were resolved.
