May 20 (Reuters) - The smallest of Louisiana's refineries was shutting down this week because of rising flood waters along the Mississippi and Atchafalya rivers, a source familiar with refinery operations said on Thursday. [ID:nN19131598]
Alon USA Energy's ALJ.N 80,000 barrel-per-day (bpd) refinery in Krotz Springs, Louisiana, about 44 miles (70 km) west of the state capitol of Baton Rouge, is the only plant next to the Atchafalaya River.
The other refineries, all located along the Mississippi continue to operate, although output has been reduced by at least 10 percent at the nation's second-largest refinery operated by Exxon Mobil Corp (XOM.N) in Baton Rouge, sources told Reuters.
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.
There are 10 refineries located along the Mississippi and Atchafalaya rivers that can process 2.4 million barrels per day of oil, or 13.7 percent of the country's refining capacity.

Magellan Midstream Partners (MMP.N) said operations were restarting at its 2.8 million-barrel storage terminal in Marrero, Louisiana. Magellan's 50,000-barrel storage terminal in Gibson, Louisiana, remained shut. Water levels have crested at Marrero on the Mississippi, while water levels were rising on the Atchafalaya at Gibson.
Exxon Mobil (XOM.N) Pipeline Co has shut two 12-inch (30.5-cm) crude line segments of the North Line system north of Baton Rouge and one 16-inch segment of the Southwest line across the river from Baton Rouge. The lines were filled with water and will remain so until flooding ends.
The Mississippi River reopened at Natchez, Mississippi, on Tuesday. Travel through a 15-mile (24-km) stretch of the river near Natchez was restricted. Fifteen vessels were waiting to transit that section of the river on Wednesday, the U.S. Coast Guard said. That portion of the river may be closed if the river level at Natchez reaches 62.5 feet (19.05 meters). [ID:nN17181374]
Barge traffic is moving along the Mississippi River with some restrictions. Barges were running near Baton Rouge, but facing difficult river conditions.
