ABSTRACT
The Refugio Oil Spill occurred on May 19, 2015, due to the failure of an underground pipeline, owned and operated by a subsidiary of Plains All-American Pipeline near Highway 101 in Santa Barbara County. The Responsible Party initially estimated the amount of crude oil released at about 104,000 gallons, with 21,000 gallons reaching the ocean. A Unified Command (UC) was established consisting of Incident Commanders from the U.S. Coast Guard (USCG), California Department of Fish and Wildlife (CDFW) Office of Spill Prevention and Response (OSPR), Santa Barbara County, and Plains Pipeline with additional participation by the U.S. Environmental Protection Agency and California State Parks. Within hours, the CDFW closed fisheries and the following day Governor Brown declared a state of emergency for Santa Barbara County. The released oil caused heavy oiling of both on and offshore areas at Refugio State Beach and impacted other areas of Santa Barbara and Ventura.
A number of factors created unique challenges for the management of this response. In addition to direct natural resource impacts, the closure of beaches and fisheries occurred days before the Memorial Day weekend resulting in losses for local businesses and lost opportunities for the public. The Santa Barbara community, with its history with oil spills and environmental activism, was extremely concerned and interested in involvement, including the use of volunteers on beaches. Also this area of the coast has significant tribal and archeologic resources that required sensitive handling and coordination. Finally, this area of California’s coast is a known natural seep area which created the need to distinguish spilled from ‘naturally occurring’ oil.
Most emergency responses, including oil spills, follow a similar pattern of command establishment, response and cleanup phases, followed by non-response phase monitoring, cleanup and restoration. This paper will analyze the Refugio oil spill response in three primary focus areas: 1) identify the ways in which this spill response was unique and required innovative and novel solutions; 2) identify the ways in which this response benefited from the ‘lessons’ learned from both the Deepwater Horizon and Cosco Busan oil spills; and 3) provide a summary of OSPR’s response evaluation report for Refugio, with specific focus on how the lessons learned and best practices will inform future planning efforts within California.
