Hundreds of barrels of oil that gushed from a ruptured coastal pipeline in scenic California this week could stiffen opposition to large oil projects that companies want to build in the state, notably those to deliver cheap U.S. crude on trains. Several proposed oil-by-rail offloading terminals in California were already being contested in light of several fiery crude train derailments since 2013 that have stoked safety concerns about spills and explosions. Now, the sight of oil washing up on the shores of Santa Barbara could further galvanize rail opponents after up to 2,500 barrels of crude leaked on Tuesday from a pipeline owned by Plains All American Pipeline LP.
