Coleman Oil identified as source of biodiesel spill in Columbia River

In Washington state, a coordinated investigation by state and federal authorities in Wenatchee has identified Coleman Oil, Inc., a fueling facility near the Columbia River, as the source of the biodiesel spill that has been leaking into the river.

The search for the source narrowed last week when spill responders identified the product as biodiesel. The investigation then focused on the facility because of its location near the river and because it handles biodiesel.

The company worked cooperatively with state and federal officials over the weekend to excavate parts of their site. What they found were leaking pipes and soils saturated with red and yellow biodiesel fuels.
