"I wish petro-folks would have the refineries as neat as their yards."
As a former partner in a refinery in Big Spring, Texas, I agree.
Alas, you change almost ANYTHING in a refinery, you are no longer grandfathered, and have to comply with cost-prohibative regulations, hearings, oversite, lawsuits, etc.
As a result, no new refineries have been built (and little capacitiy added or changes made, cosmetic or otherwise) for 30 years.
In sum, thank Jimmy Carter for the ugly refineries.
