Exxon reports valve leak at Chalmette, LA, refinery

Nov 30 (Reuters) - Exxon Mobil Corp reported a release of hydrogen fluoride
due to a valve leak on Tuesday at its joint-venture 192,500 barrel-per-day
Chalmette, Louisiana, refinery, according to a filing with regulators.

The company has isolated the valves that were leaking, the filing with the
U.S. National Response Center showed.

The cause of the leak was unknown.

The filing did not specify which unit was involved in the malfunction or any
impact on production.

Exxon operates the refinery on the east side of New Orleans, which is a
50-50 joint venture with Venezuela's national oil company PDVSA.
