I will have to give you my login/password. Probably not a good idea for *capitalistic* reasons, at least.
I will summarize the rest of the article though:
1) No refineries were built since mid 70s
2) Some refinery capacity was added to existing ones
3) Profits from refining are high right now
4) But, may not last long to convince refinery companies to add capacity
5) Industry is heavily regulated with questionable profits
6) Katrina resulted in loss of refinery capacity
7) Outside the US refiners opened up supplies sensing good profits. Gas prices in the US declined since some.

But, the downside is more reliance on foreign refined products (in addition to Crude).

The following closing lines summarizes it all:

But the lack of refining investment in the U.S. relative to the rest of the world could add to the growing reliance of the U.S. on imports, depending on how fast oil demand grows. Last year, imports made up 9.5% of U.S. demand for refined products, up from 7.4% in 1999.
