Narrative
Operations technician was notified of possible leak at facility by pipeline control at 10:54pm. Pipeline control had been notified by customer operation personnel of leak in oppl facility. Oppl facility was esd'd at 11:15 pm at operation technician's request base on information obtained from customer operations. Pipeline control shut down the facility and product was allowed to vent. Station piping was vented to 190 psi and operations personnel isolated the affected section. After section was blown down the affected pipe nipple was removed and replaced. Flow to facility was restored at 2:50 am 6/29/2017. Nrc report 1182661 48-hour follow-up made on 6/29/2017 at 13:26. At the bushton meter, the thermal relief piping was removed and administrative procedures (williams' car seal program) were put in place to handle thermal relief requirements; this was done by tagging valves open that are needed for thermal relief. P&ids were also marked up to show the locations of these valves as well as an moc to cover the changes. The failed pipe nipple that was removed was replaced by a schedule 160 nipple and valve and was plugged. All sites on oppl are currently being surveyed for thermal relief lines that are not adequately supported and a plan is in place to remove those that can be removed and adding supports for the others that can't be removed but where thermal relief is necessary.
