Narrative
An operator was performing a facility inspection and discovered a product release from a 1/4" fitting on the relief tubing at the discharge side of mainline unit #3. The release was isolated by closing the upstream and downstream valves on the relief system. Clean up activities commenced and impacted soils were hand excavated, containerized, and properly disposed. The 1/4" fitting was removed and sent in for analysis. The piping system is protected by another existing thermal relief system. Two new 1/2" fittings were ordered to replace the failed fitting and one additional 1/4" fitting at the facility. The rest of the thermal relief systems at the facility were inspected and no evidence of leaks was found. Update 1/17/19: results of the analysis indicate the fitting was bent and debris possibly prevented proper sealing. Replacement of the existing 1/4' fittings with new 1/2' fittings has been completed 20 cubic years of soil was removed. Supplemental (01/10/2019): update to part a 5. Correction of longitude supplemental/final (01/18/2019): update to part g6-6 sub-cause and part h with results of analysis and repairs completed.
