Narrative
On 9/25/2015, at 23:00, the gasket at the four-inch vent pipe flange failed on the line 02 prover at houston station. The release was discovered by an employee at 23:31 and the line was immediately shutdown and the station and prover isolated. A technician responded at approximately 00:15 on 9/26/2015 and completed further isolation (lockout/tagout) and draining of the prover. The line was restarted on 9/26/15 at 01:38. On 9/26/15 at 09:20 the texas state emergency response center was notified and they in turn notified tceq. The nrc was notified on monday 9/28/2015 at 15:11 when it was determined that the cost of cleanup and recovery were likely going to exceed $50,000. The failed gasket was installed by a qualified colonial technician in january 2015 following a water draw of the prover. Incident analysis of the event determined that the basic causes of the gasket failure were: 1.) failure to follow colonial's cm-111 bolted connections procedure when the gasket was replaced in january 2015. 2.) failure to follow colonial's material & equipment specification ms-07-06 for proper marking of gaskets with date of manufacture and receipt when the gasket was received at the warehouse. Following the determination that the technician's actions were a contributing factor to the accident, the technician's oq qualification to perform flange bolting procedures was disqualified in accordance with colonial's operator qualification program manual. As a remedial action, the technician was required to re-qualify using the performance verification method. Two corrective actions have been identified to improve the process of tracking gasket shelf life.
