Narrative
On monday october 15th about 9:25 am a pipeline technician discovered a release at tank 1000 at spanish trails station. After discovery and observation it was estimated that leak volume would require a nrc report. Nrc was called at 10:25am cst (nrc#1227515). Caller was on hold for an extended time with call concluding at 10:49. Clean up and remediation of area began immediately. A 48 hour nrc follow-up was made to the nrc at 12:31 the following day (report # 1227605). During the incident investigation it was observed that a communication disruption was identified on saturday october 13th and had pipeline technicians and houston control center troubleshoot all weekend. The incident investigation identified that the plc logic at spanish trails was set incorrectly and the controls engineer discovered that the mechanical safety switch input was performing a local reset after a power outage. This was reprogrammed to adjust that action and prevent an erroneous reading. Other sites in the area that might have the same logic incorrectly set up after a power outage were reviewed and corrected where necessary.
