Chevron Phillips Closing Massive Baytown Chemical Complex

Chevron Phillips shut down its massive Cedar Bayou petrochemical complex in Baytown on Sunday as flooding overtook much of the Houston region.

Chevron Phillips is undergoing a sitewide shutdown of one of the nation's largest chemical campuses, according to a filing with the Texas Commission on Environmental Quality. The plant is currently undergoing a $6 billion expansion that's scheduled for completion by the end of 2017.

The facility is scheduled to be closed through Sept. 6, according to the state panel.

The chemical company is a joint venture between Chevron and Houston's Phillips 66.

The news follows confirmations from Exxon Mobil and Royal Dutch Shell that they're temporarily halting operations in Baytown and Deer Park, respectively.
