Narrative
At 1500 cst on 06 dec 10 cpl field personnel confirmed a release on the 8" van gathering system near the van station. The release source was a pinhole @ the 6 o' clock position; directly below the line is a sewer opening that feeds to a nearby water treatment facility. There are reports of an oil sheen in the treatment facility. Chevron production and cpl personnel have deployed skimmer units and a vacuum truck @ the treatment facility; containment boom, skimmer units and a vacuum truck have been deployed @ the little sandy creek outfall area, the point of discharge from the treatment facility. Cpl crew installed a temporary clamp to prevent further leakage. The following day, cpl crew removed temporary clamp & installed a plidco mechanical sleeve. The sewage treatment plant and piping have been cleaned of all contaminates. The section of pipe where the leak occurred will remain out of service until further notice. Cpl has made the decision to idle the entire van crude system & we are currently in the process of removing the crude oil line fill.
