Such local supply disruptions due to localized events could be mostly avoided, if states would get together and agree on a common formulation for gasoline. Here is one of the few areas where Federal leadership might be exercised to the common good (iffy, but possible). That way, gasoline supply would be easily transferable from one area of the country to another. Imagine the chaos if each state had their own standards for electricity generation and transmission? California would be even more hosed than it currently is.
