No.. New refineries have not been built because it is cheaper to increase
the capacity of existing ones. These retrofits are subject to all the
enviornmental regulation that a new refinery would be subjet to.

That's not true.

There are a million ways to expand any existing business -- refineries
included -- without tripping the government's "regulation Nazis."

Whatever the oil companies have done by way of expansion-in-place has been
terribly limited by the financial burden of overly-restrictive EPA rules --
to the ultimate detriment of everyone.
