Largest drop in the records in 15.2 million BBL (January 1, 1999). Other big drops in 1998, 2000, and 2001.

I plan to attend the EIA Conference in April

Don't overlook the big increase in blending components to window dress the gasoline drawdown offset. Looks like the BC's were up about 3 million barrels worth over last week offsetting a big chunk of that gain in "gasoline and blending stocks" noted in the 4 million barrel gain. Blending components are now up 5.4 million barrels over last year.

Can someone tell what "blending components" largely consist of? Does ethanol fall into the category?

According to http://www.ethanolrfa.org/industry/statistics/
2007 fuel ethanol production is averaging 12M barrels/month, steadily increasing into the fall. This should show up somewhere in TWIP, right?
