Narrative
On 7/13/17, magellan's contractor was performing excavation on the east houston to el paso 18" line section at mp 141.8. The contractor's excavation equipment made contact with a mainline pipe tap causing a release. The pipeline was active at the time of the event. Operations control issued a code red based on a call from field personnel saying the contractor struck the pipeline. Psap (public access safety point) and nrc were notified. The nrc report number is 1183933. Hwy 20 was closed during the incident. Within 3/4 mile radius of the incident, 14 families were evacuated and 1 sheltered in place. Evacuees were allowed to return to their homes the same evening. Records indicate the mainline pipe tap was installed prior to 1995. The section of the pipe that included the pipe tap was cut out and replaced with a pre-tested piece of pipe. Future preventative actions including obtaining smart pig data to identify potential buried pipeline appurtenances and reviewing this data with excavation personnel prior to beginning work. Accident response consists of only long term remediation and is under the response action plan submitted to the texas railroad commission. 48-hour nrc update: #1184112, 7/14/2017 17:02 supplemental/final updates(06/17/2019): parts a11, d8e, d8g and part h narrative
