While efforts continue in the cleanup of the California oil spill, the number of personnel deployed is down more than 10 percent, a response team said.
Line 901, a pipeline system operated by Plains All American leaked as much as 2,500 barrels of oil in Santa Barbara County in mid-May. About 500 barrels may have reached the waters off the coast of Refugio State Beach in a release the Environmental Protection Agency said was the worst spill in California in the last 25 years.
Sheen has long since disappeared from the California coast, though so-called tar balls may be present on some beaches. A unified command working on cleanup operations reports no increase in recovery of oily water mixture since Thursday. The amount of combined oiled vegetation, sand and soil, however, has increased 30 percent since then to close to 190,000 cubic feet.
Plains, in an incident response, said the number of personnel deployed is down more than 10 percent from Thursday to a combined 966.
The federal Pipeline and Hazardous Materials Safety Administration said it found "extensive" corrosion on the breached pipeline, with walls degraded by as much as 74 percent of their original thickness in some locations.
Plains said it had conducted a system inspection two weeks before the May 19 spill, though results weren't returned until after the incident.
