Chevron has cleaned up less of the diesel that leaked from
its pipeline near a freshwater lake in Utah than it had
originally thought, the company said Wednesday.
Chevron is dealing with the fallout of the March 18 leak,
which resulted in 600 bbl of diesel from its refinery in Salt Lake City spilling
into marshes close to a freshwater lake in Willard Bay State
Park, Utah. The company has to date recovered 354 bbl of the
fuel, down from the 500 bbl it had said it had collected
Friday, Chevron spokesman Gareth Johnstone said.
"After allowing the recovered diesel and water volumes to
fully separate, and using improved gauging methods, the total
volume of diesel recovered has been revised down," Mr.
Federal regulators have barred Chevron from restarting the
line until the company completes a checklist of corrective
actions, including a metallurgical test of the failed
About 90 Chevron employees and contractors joined state and
federal government workers to clean the site, recovering about
250 bbl of diesel as of Friday. The fuel hasn't been found in
the Willard Bay reservoir, a source of drinking water for the
area, said Matt Allen, spokesman for the US Environmental
"We're not seeing anything that would impact drinking water
standards," Mr. Allen said.
Chevron is investigating the cause of the leak, with an
initial check pointing to a seam failure, the company said.
Chevron last inspected the pipeline in 2007, according to the
Pipeline and Hazardous Material Safety Administration, the
federal agency in charge of pipeline safety.
PHMSA conducted its own inspection in April 2011 and
September 2012, resulting in the agency sending a "letter of
concern" to Chevron because the company hadn't finished an
analysis of why the same pipeline system leaked 22 bbl of oil
in April 2010, PHMSA said.
