SAN FRANCISCO (AP) — As an oil tanker that struck a San Francisco-Oakland Bay Bridge tower was deemed safe to leave port on Friday, the Coast Guard was calling for reconsideration of rules that allow large ships to sail in fog near the span. Capt. Cynthia Stowe, a top Coast Guard official, on Thursday asked the San Francisco Bay Harbor Safety Committee to reconsider the rules. The 752-foot Overseas Reymar scraped a section of a protective fender on a bridge tower Monday as it headed out to sea.
