Small spill reported at Exxon refinery in Mont.
BILLINGS, Mont. (AP) — State officials and a company spokesman say a small amount of oil has spilled into Montana's Yellowstone River from the Exxon Mobil refinery in Billings.
Refinery spokesman Dan Carter said Wednesday that the Texas-based company was investigating the source of the spill after its discovery Tuesday afternoon.
Carter says less than a gallon spilled. Absorbent boom was placed on the river to keep the product from going downstream.
State officials say a sheen from the oil was seen along the Yellowstone where cooling water from the refinery flows into the river.
Montana Department of Environmental Quality spokesman Chris Saeger says the sheen initially was about a foot wide and stretched for roughly 100 yards.
Officials say downstream water users were notified but no problems were reported.
