RICHMOND, Calif. (AP) -- Chevron Corp. says it will use corrosion-resistant pipes at the San Francisco Bay area fuel refinery damaged in an August fire.
The petroleum giant says in a letter released on Wednesday that thinning and corrosion in refinery pipes apparently caused the blaze in its crude unit No. 4.
The Richmond refinery has been operating at about 60 percent capacity since the fire.
The Contra Costa Times (http://bit.ly/PYskRS  ) says Chevron will replace pipes with chrome alloy to prevent corrosion.
Refinery general manager Nigel Hearne's letter to Richmond and Bay Area Air Quality Management District officials says Chevron hopes to complete repairs and restart unit No. 4 early next year.
