Narrative
A field technician was installing locks on several manifold valves when a leak was discovered on valve px13. Upon further investigation, the cause of failure was determined to be a broken pipe nipple (1/2 inch schedule 160) threaded into the valve flange, which is the discharge line of the px13 dtr (differential thermal relief) system. Repairs were made prior to restarting the line. A total of 0.54 cubic yards of contaminated soil was removed from the site during clean-up.
