On Tuesday an onshore pipeline ruptured along the scenic coast north of Santa Barbara, California, spilling an initial estimate of 21,000 gallons of oil into the ocean and onto beaches before the flow could be controlled. Later reports increased this estimate to 105,000 gallons. What caused the spill is still under investigation, and clean-up activities are ongoing. The incident brought back memories of the 1969 Santa Barbara Channel oil spill that effectively shut down oil development offshore California for almost 10 years.
