Kirby Inland Marine has agreed to pay $15.3 million to resolve the federal state claims of harming natural resources during the 2014 oil spill from Kirby barge in the Houston Ship Channel. In 2016, Kirby Inland Marine paid $4.9 million in civil penalties and injunctive relief measures to help prevent future oil spills and improve company operations. More compensation from Kirby Inland Marine was sought after for the 168,000-gallon oil spill. Kirby Inland Marine alleges the oil spill occurred when a tow boat attempted to push a 300-foot-long oil barge across the Houston Ship Channel and collided with a 585-foot-long deep-draft bulk cargo ship.
