Last July, The Silvertip Pipeline near Laurel spilled 63,000 gallons of crude oil into the Yellowstone River. What caused the 12-inch pipeline to rupture is still under investigation by the U.S. Pipeline and Hazardous Materials Safety Administration.

The Montana Department of Environmental Quality is asking for public comment on an agreement with ExxonMobil regarding to the cost of clean-up.  DEQ Public Information Officer Mary Ann Dunwell details the agreement.

The 30-day public comment period on the Administrative Order on Consent ends Tuesday February 21, 2012 at midnight. For more information about the Silvertip pipeline spill visit
