The Latest: Estimated 230,000 gallons of oil spilled

DOON, Iowa (AP) — The Latest on the crude oil leaking after a train derailment in northwest Iowa (all times local):

4:10 p.m.

A railroad official says 14 of 32 derailed oil tanker cars in the northwest corner of Iowa dumped an estimated 230,000 gallons (870,619 liters) of crude oil into floodwaters, with some making its way to nearby rivers.

BNSF spokesman Andy Williams confirmed the details Saturday. He says nearly half the spill had been contained with booms near the derailment site and an additional boom placed approximately 5 miles (8.05 kilometers) downstream. Williams had earlier said 33 oil cars derailed.

Williams says oil will be removed from that containment site with equipment to separate the oil from the water.

The railroad will focus on environmental recovery. Williams says "ongoing monitoring is occurring for any potential conditions that could impact workers and the community and, so far, have found no levels of concern."

Iowa Gov. Kim Reynolds is set to visit the site of an oil train derailment and oil spill in the northwestern corner of the state.

Reynolds' office says in a news release that she plans to survey the site Saturday afternoon. The governor is also spending the day touring other areas hit by flooding in recent days.

The derailment of 32 oil tanker cars Friday just south of Doon has caused concern for towns and cities downstream, as far south as Omaha, Nebraska, about 150 miles from the derailment site. Omaha's public water utility — Metropolitan Utilities District — is monitoring pumps it uses to pull drinking water from the Missouri River.

The spill reached the Rock River, which joins the Big Sioux River before merging into the Missouri River at Sioux City.

Rock Valley, Iowa, just southwest of the derailment, shut off its water wells within hours of the accident.

Crews are working to clean up a BNSF oil train derailment in Iowa that dumped crude into floodwaters, while officials seek to get a handle on the extent of the spill and its cause.

BNSF spokesman Andy Williams says 32 oil tanker cars derailed Friday just south of Doon, leaking oil into surrounding floodwaters from the swollen Little Rock River. He said Saturday that the cause of the derailment hasn't been determined. The amount spilled also isn't yet known.

Williams says crews have been skimming oil from floodwaters. They're also building a road parallel to the tracks to try to get to the derailed and partially-submerged oil cars.

The train was carrying tar sands oil from Canada to Oklahoma for ConocoPhillips. ConocoPhillips spokesman Daren Beaudo says each tanker can hold more than 25,000 gallons.
