TEXAS CITY, Texas, Feb 24 Magellan Midstream
Partners (MMP.N) shut an 18-inch diameter (46-cm) oil products
pipeline at Texas City, Texas, after a 6,000-barrel leak of
gasoline, the company said Thursday.
The pipeline is a common carrier that runs 40 miles (64 km)
north from Texas City to Pasadena, Texas, and is one of a
number of pipelines between the two refining centers, officials
said. Texas City is about 40 miles southeast of Houston.
There was no word from the company or other officials on
possible effects on fuel supplies.
Gulf Coast gasoline gained 0.25 cent and Group 3 diesel
rose 1.40 cents after the pipe shutdown was announced.
Thirty nearby homes were evacuated following the leak's
discovery and a state highway along with several streets were
closed due to spilled gasoline, which could be smelled around

Coast Guard Commander Jim Elliott, who is overseeing the

safety," Elliott said.
The leak was discovered about 1 a.m. local time (0700 GMT),
a company spokesman said.
"It was discovered in the control room when there was a
sudden pressure drop," Magellan spokesman Bruce Heine said.
Valves on either side of the pipeline leak were closed, but it
was unclear whether additional gasoline would spill as the
isolated section drained.
The company planned a revised estimate of the spill volume
later, Heine said.
Texas City abuts Galveston Bay and the spill occurred near
a small bayou that has been boomed off as a precaution, but no
water had been affected, Elliott said. A flood gate was closed
between a lake fed by the bayou and Galveston Bay as a
