A 5 year project, modernizing the oldest refinery in the US.
At the time they said it was equivalent of building the US' 7th largest refinery inside the US' 4th largest refinery.
Largest construction project going on, in the US, at the time.
At one time there were 15,000 guys working on the plant.
The 5 year project cost $3.8 billion and increased production by 260,000 barrels a day.
-—The 5 year project cost $3.8 billion——
Which I take to mean the Raven refinery at $500 million is not a really big effort
