(AP) — Firefighters, emergency workers and officials from Plains All American Pipeline had gathered last week at a fire station preparing to train for the worst — an oil spill — when a 911 call came in reporting a noxious smell in the air at a nearby beach. By the time the firefighters traced the source of the spill to a ruptured underground pipeline, thousands of gallons of crude oil had escaped. What was done that day to stop the spill and protect some of the most fabled coastline in California has come under scrutiny, as officials continue cleaning up the mess created by a leak estimated at up to 101,000 gallons and trying to figure out what went wrong. According to disclosures so far, it took Plains about 90 minutes after the oil spill was confirmed to notify the National Response Center, a clearinghouse for reports of hazardous material releases that coordinates responses. Linda Krop, chief counsel of Environmental Defense Center, said she was at the shore until 10 p.m.
