>>CA refinery product network is isolated from other parts of USA mostly because of stringent environmental requirements. As a result CA customers may rely only on products made in CA, and limited supply market causes higher prices. By similar reasons HI has the highest gas price in the country (CA is close second).

I prefer to stay within economical categories. Have you ever heard about free market? Someone may say that it caused by greed. So what?
There are two factors defining prices in free market: supply and demand. If you put limits on supply (doesn't matter for what reason, it could be a concern about greed) then price goes up (or, as some greed fighters learned in other countries, the product disappears).
