Congress Scolds BP for Rusty Pipes

Congress scolded executives at BP, Thursday, for allowing Alaska's Prudhoe Bay oil field pipelines to become so full of corrosion there was a major oil spill in March and partial closure of the oil field on August 7th 2006. Once repairs are completed on the pipeline at the end of October, lawmakers will allow BP to reopen the oil field.

According to BP engineers, corrosion in these types of pipelines is considered extremely rare and the only way to find weak spots in the pipeline is with pigging. The problem is BP hadn't "pigged" their Alaskan pipelines in 14 years!
