Crews were still working to suppress flare-ups Saturday as a fire at a Louisiana oil refinery burned for a second day along the banks of the Mississippi River, while residents worried about health effects from the fumes and black smoke.
Tests have so far found “non-detectable air quality impacts” from Friday's massive fire, Marathon Patroleum said in a emailed statement Saturday. The state Department of Environmental Quality and a third-party contractor were conducing the tests.
