Contractors have rung up $5.3 million in costs for the beached and broken barge Davy Crockett, as of the end of last week.

And that’s before they’ve even formulated a plan for removing the 431-foot derelict from the north bank of the Columbia River between Vancouver and Camas.

Workers have cleared away enough debris that divers were able to safely access fuel tanks at the bottom of the vessel. They found what was described as remnant amounts of heavy bunker fuel, which has the consistency of peanut butter.

“We did find some bunker fuel remaining in the tanks,” said Jim Sachet, cleanup coordinator for the Washington Department of Ecology.

Samples of the fuel confirmed assumptions that the material contained no heavy metals or polychlorinated biphenyls. Trace levels of PCBs were previously discovered leaking into the river. The substance, a suspected carcinogen, was discovered in samples of lubricating oils onboard the barge, which was originally built as a World War II freighter.
