ROUGH CUT (NO REPORTER NARRATION) The Intercontinental Terminals Co petrochemical storage tanks that had been burning in Deer Park since Sunday were extinguished on Wednesday, the company said, lamenting the incident.

The blaze at a site along the Houston Ship Channel in Deer Park, Texas, began Sunday when a leak from a tank containing volatile naphtha ignited and spread to others in the same complex, the company said.

The tanks hold tens of thousands of barrels of products used to boost gasoline octane, make solvents and plastics.

"We are sorry for what has happened.

We're sorry to our neighbors," Company spokeswoman Alice Richardson said on Wednesday.
