Unocal Point Conception Decommissioning Project

[Web page up to date as of 05/24/2017]

What's New

In February of 2014, Unocal successfully completed restoration efforts with the Cojo Marine Terminal and Point Conception Facilities Decommissioning Project. The last remaining component of the decommissioning project is monitoring and remediation, when necessary, of the exposed pipeline removal site. In October of 2013, 200 linear feet of two buried 4-inch diameter pipelines was removed along the access road to the Percos Beach seacliff.

Pre-Construction and Post-Construction Site Photos

In the fall of 2006, the Energy Division received pre- and post-construction photo documentation for the decommissioning of all three former Unocal Chevron facility sites at the Cojo Ranch. Shown below are “before and after” photographs of the three locations ( Cojo Bay, Government Point, and Point Conception) that were once used to accommodate oil and gas production facilities.

This site houses facilities in three locations (Cojo Bay, Government Point and Point Conception) that were once used to accommodate oil and gas production from offshore platforms (Harry and Herman) in the Point Conception field. The platforms have been removed and the existing marine terminal and production facilities are no longer active. These facilities were removed by the end of 2004. Since then, Unocal and its affiliates have worked to clean up and restore these sites to pre-commission standards.

Cojo Bay Marine Terminal Site

Unocal's former Cojo Bay Marine Terminal site is located to the northeast of Point Conception, approximately 45 miles west of the City of Santa Barbara and 13 miles south of the City of Lompoc.

Government Point Production Facilities Site

Unocal's former Government Point Facilities site is located to the northwest of Point Conception, approximately 45 miles west of the City of Santa Barbara and 13 miles south of the City of Lompoc.

Point Conception Well Location

Unocal's former Point Conception well site is located to the northeast of the tip of Point Conception, immediately north of the Pt. Conception lighthouse facilities.

Cleanup Activities

Unocal's cleanup activities at Point Conception consist of a number of projects associated with the company's Cojo Bay marine terminal offshore loading line, Government Point production facility and various storage wells.

Cojo Bay Marine Terminal

  • The last barge loading at the Cojo Bay marine terminal occurred in 1987.
  • The terminal was placed under caretaker status in 1993.
  • The offshore mooring system was removed in the early 1990s.
  • Sections of offshore loading hoses were removed in late 1997.
  • The pipeline has been flushed with seawater to remove residual oil.

Government Point Production Facility and Wells

  • The Government Point production facility was last used in 1993 and placed under caretaker status that same year.
  • Four onsite oil wells were idled in 1993 and abandoned in 1999, which involved the cutting and capping of each well at a depth of 8 feet below ground surface and complete removal of the well cellars.
  • Four oil storage tanks have been emptied of remaining product and rinsed clean.

Past Activities

  • Phillips Petroleum Company constructed the Cojo Marine Terminal onshore facility in the early 1960s to accommodate the development of the State offshore tract PRC 2207 from Platform Harry. In the early 1970s, Phillips Petroleum abandoned and removed Platform Harry and all related onshore processing equipment connected to the marine terminal. Between Phillips' Platform Harry and Texaco's Platform Herman, 13 million barrels of oil/condensate and 747 billion cubic feet of natural gas were produced.
  • Union Oil Company constructed the Government Point production facility in the early 1970s. The site produced oil and gas from the Point Conception field (State Tidelands Lease PRC 2879). Production consisted of 21 million barrels of oil/condensate and 12 billion cubic feet of natural gas.
  • Unocal acquired the remaining Cojo Bay marine terminal facilities in 1973 in order to transport oil production from the Government Point facility to the marine terminal and onto oil tankers via an offshore loading line.
  • February 9, 2000, Unocal submitted an application to the Energy Division to decommission the facility at Cojo Bay and Government Point.
  • An Initial Study was conducted under the California Environmental Quality Act, which analyzed potential environmental impacts of the Phase II Abandonment Plan. Some impacts were found to be potentially significant, however mitigable. A mitigated Negative Declaration (02-ND-02) was prepared and circulated for review early in 2002.
