Narrative
While conducting scheduled block valve exercises on ls-90/50/60 (concord to fresno), the maintenance crew discovered a stain around the willow pass block valve in the city of antioch, ca., measuring approximately 4.5' in diameter. The buried portion of the valve was excavated and it was determined that the leak was coming from a threaded plug in the bonnet of the valve. This portion of the line was isolated and the plug was removed and replaced. The plug was found to have little to no teflon tape left on the threads. A new plug was installed and successfully held test pressure during both an hour long static test and hour long running test.
