UPDATE 1-Enterprise Products says Texas NGL pipeline shut

(Adds details, comments from Coast Guard, Chevron Phillips Chemical Co. LLC and city spokeswoman)

NEW YORK, June 25 (Reuters) - Enterprise Products Partners L.P. (EPD.N) on Wednesday shut its 125,000 barrel-per-day Seminole pipeline that transports propane and other natural gas liquids from West Texas to Mont Belvieu, Texas, after a leak was discovered in Pasadena, Texas, near Houston, a company spokesman said.

The leak was detected at 10:30 a.m. CDT (1530 GMT), and the section of the pipeline was isolated and crews dispatched, the company said.

There were no injuries, according to Enterprise spokesman Rick Rainey.

Rainey said the cause of the leak was not determined and no restart estimate was available. The NGLs vaporize when exposed to air, so usually the products do not pool when leaked, Rainey said.

City of Pasadena spokeswoman Jennifer Banks said there were no injuries and no threat to nearby residents.

Banks said the line was shut and any remaining product in the line was being bled off.

Shipping on the nearby Houston Ship Channel was not affected, the U.S. Coast Guard said.

Chevron Phillips Chemical Co LLC's facility nearby was not affected, according Brian Cain, spokesman for the 50-50 joint venture of Chevron Corp (CVX.N) and ConocoPhillips (COP.N).
