(Updates with Morganza Spillway, nuclear facilities)
May 11 Heavy flooding in the U.S. Midwest shut
Ohio River terminals, limited barge movements and threatened to
disrupt refinery operations along the Mississippi River to the
Gulf of Mexico on Wednesday.
There are 10 refineries, including the second-largest U.S.
refinery, located along the Mississippi River, that can process
2.4 million barrels per day of oil, or 13.7 percent of the
country's refining capacity.
Valero Energy Corp's (VLO.N) and Motiva Enterprises
(RDSa.L) refineries in St. Charles Parish, Louisiana, west of
New Orleans, will be flooded if the Morganza Spillway, which
would send floodwaters from the Mississippi down the
Atchafalaya River, is not opened, the St. Charles Parish
emergency preparedness director said on Wednesday.
Scores of U.S. heartland rivers from the Dakotas to Ohio
have flooded following a snowy winter and heavy spring rains,
feeding near-record crests on the lower Mississippi River.
Valero Energy Corp's 180,000-bpd refinery in Memphis,
Tennessee, continued operating on Wednesday in the center of
the worst flooding where high waters forced evacuations in
residential areas. The river crested near 48 feet (14.6 meters)
on Tuesday at Memphis.
The U.S. Army Corp of Engineers was planning to open the
Morganza spillway by early next week, which will send flood
waters from the Mississippi to the Atchafalaya River, likely
disrupting operations at Alon USA Energy's (ALJ.N) 80,000 bpd
Krotz Springs, Louisiana, refinery.

Nearly 20 percent of barge terminals the U.S. Coast Guard
monitors on the Ohio River remained closed on Wednesday. The
Smithland Lock and Dam at mile marker 918.5 on the river
remains closed, obstructing barge traffic both up and
The tanker Zaliv Baikal turned back from going to a dock in
Baton Rouge because its captain didn't think the vessel had
enough clearance beneath the I-10 Bridge over the Mississippi
at Baton Rouge.
Berths at Exxon's docks in Baton Rouge were flooding on
Wednesday, which may make docking tankers difficult in the
coming days, according to sources familiar with refinery
operations. Exxon said the refinery continues to operate
Barge traffic is moving along the Mississippi River with
some restrictions and no closures. Barges were running near
Baton Rouge, but facing difficult river conditions.
Mississippi River restrictions include length of barge (no
greater than 600 feet), energy requirement (greater than 250
horsepower), speed (3 miles/hour) and prior notification
requests before navigation starts. To that end, barge traffic
is open in places like St Louis and Memphis with restrictions.
