HANLONTOWN | A pipeline break Wednesday morning near Hanlontown spilled approximately 138,600 gallons of diesel.
The break was discovered about 8 a.m. in a 12-inch line owned by Magellan Midstream Partners near 390th Street and Wheelerwood Road.
Local officials were initially told the break spilled about 63,000 gallons, but a spokesman for Magellan said Wednesday afternoon that the Tulsa, Oklahoma-based company believes a total of 3,300 barrels, or 138,600 gallons, had spilled from the line.
Much of the fuel pooled in a farm field.
Magellan, which reported the spill to federal regulators, will remove the diesel and dig up the contaminated soil, said David Miller, an Iowa DNR environmental specialist.
The Iowa DNR and Environmental Protection Agency was on site with local officials and Magellan representatives.
The cause of the leak remains under investigation.

HANLONTOWN | Crews have sucked up about 25,000 gallons of diesel and a slush-diesel mixture that came from a pipeline that broke north of Hanlontown Tuesday morning, officials said.
Crews discovered the break about 8 a.m. near 390th Street and Wheelerwood Road.
The Iowa Department of Natural Resources says it was informed the spill was about 63,000 gallons, or 1,500 barrels, of fuel.
The fuel had pooled in a farm field.
As of 1:30 p.m., about 25,000 gallons of diesel and diesel-contaminated snow had been removed, a Worth County official said.
Crews were hauling in rock and lights so the clean-up and repair efforts could continue throughout the night.
Update: Hanlontown pipeline break hasn't impacted nearby slough, officials say
1:30 p.m. Update
HANLONTOWN | An approximately 63,000 gallon spill from a broken pipeline near Hanlontown does not appear to have affected nearby wildlife areas, officials say.
The Mason City office of the Iowa Department of Natural Resources was notified about 8 a.m. Wednesday that a 12-inch pipe owned by Magellan Midstream Partners had leaked diesel near 390th Street and Wheelerwood Road, said David Miller, an Iowa DNR environmental specialist.
That's near Willow Creek, which runs just east of Wheelerwood, and the Hanlontown Slough Waterfowl Production Area, which is on the west side of Wheelerwood just south of 390th Street.
"There's a big pool of diesel fuel out in a field and it has not gotten into Willow Creek or the Hanlontown Slough as far as we can tell," said Miller, of the Mason City office. "(Magellan's crews) going to recover all the liquid product and they're going to excavate all the contaminated soil."
Miller was told the spill involved 1,500 barrels of fuel, which is roughly 63,000 gallons.
The Environmental Protection Agency and Iowa DNR have joined Magellan and local officials at the scene, he said.
A stretch of Wheelerwood -- from 390th to 410th streets -- has been closed so the Tulsa, Oklahoma-based pipeline company can get crews in to repair the leak and clean up the mess.
Although local officials and Magellan's representatives initially said one residence was evacuated, a spokesman for the company later said that was incorrect and no one was evacuated as a result of the spill.
The break is roughly three miles north and one mile east of Hanlontown.
That's about a half-mile west of Interstate 35.
Pipeline break reported near Hanlontown
Our earlier story:
HANLONTOWN | At least one residence has been evacuated for a pipeline break near Hanlontown.
The break occurred Wednesday morning in a line owned by Magellan on Wheelerwood Road near 390th Street, said Worth County Engineer Rich Brumm.
He said at least one residence in the immediate area was been evacuated.
Worth County Emergency Manager Ray Huftalin said the pipeline that erupted was carrying diesel.
"The area is secured and there's no threat to anybody," he said.
Wheelerwood is closed from 390th to 410th streets so crews can get heavy equipment in to fix the break and clean up the mess, Brumm said.
The incident is just north of the Hanlontown Slough Waterfowl Production Area, a 939-acre state-owned wildlife area.
