The closure of refineries in California will impact prices everywhere. This spills over world wide. There is X demand and if X-one gallon, then it has to come from somewhere and classic supply demand is at work. Price will go up exponentially to supply the places that are short of supply. So, that means less refining in California will lead to gasoline jobbers going to other markets to buy gasoline leading to price impacts in other markets. Someone somewhere will be willing to supply the special boutique blends of gasoline in California.
Just as Middle Eastern turmoil impacts crude oil prices, refined product is dictated by risk and costs. And importing gasoline from Indonesia, Bahamas, Texas or wherever, does not replace refining capacity. It means people have to drive less to keep from losing value. Further, the Jones Act means it has to be US ships hauling the finished products.
So, look at what prices are going to do. Go up, up, and away. Enjoy.
