Responders monitoring oil spill on Columbia River

KALAMA, Wash. (AP) — State and federal officials are responding to an oil spill on the Columbia River between Oregon and Washington.

Coast Guard officials said the oily sheen was estimated at about 3 miles long Wednesday afternoon and appeared to be dissipating since it was first reported that morning.

Officials said the source of the spill was no longer actively discharging into the river and pollution responders also determined that the oil was too thin to recover.

The spill was first reported near Kalama and was moving downriver.

Responders with the state Department of Ecology also went out on the water to collect samples to find the spill’s source.

Officials said there have been no signs of animals in distress.
