Incident Narrative

REVISED 2-10-2021 BY AMERICAN MIDSTREAM (LOUISIANA INTRASTATE), LLC. 3CM RECEIVED A CALL AT 1750 HOURS FROM BEVERLY CONSTRUCTION CO., LLC (BEVERLY CONSTRUCTION) STATING THAT THEIR SUBCONTRACTOR, MIXSON BORING, WAS CONDUCTING BORING ACTIVITY AND STRUCK OUR LINE AS THEY WERE RETRIEVING A CASING ACROSS HIGHWAY 23. BEVERLY CONSTRUCTION WAS ORIGINALLY SUPPOSED TO CONDUCT THE DIRECTIONAL DRILLING OPERATIONS ALONG E. OAK GROVE LN. BEVERLY CONSTRUCTION HAD SUBMITTED A ONE CALL TICKET FOR THE DIRECTIONAL DRILLING; HOWEVER, AT A LATER DATE BEVERLY CONSTRUCTION SUBCONTRACTED MIXSON BORING TO COMPLETE THE DIRECTIONAL DRILLING. THE 6-INCH PIPELINE WAS PROPERLY MARKED BY 3CM AFTER THE ONE CALL TICKET WAS RECEIVED FROM BEVERLY CONSTRUCTION, BUT DUE TO THE TIME LAPSE ON BEVERLY GETTING STARTED THEIR ONE CALL TICKET HAD EXPIRED AND A NEW TICKET WAS REQUIRED. TO 3CM'S KNOWLEDGE, MIXSON BORING DID NOT SUBMIT A ONE CALL TICKET PRIOR TO BEGINNING DIRECTIONAL DRILLING OPERATIONS. WITH THAT SAID, THIS INCIDENT WAS PREVENTABLE AND MIXSON BORING & BEVERLY CONSTRUCTION ARE THE LIABLE PARTY AS THEY STRUCK THE 6-INCH NATURAL PIPELINE WHILE CONDUCTING DIRECTIONAL DRILLING OPERATIONS. THE FIRST DROP IN PRESSURE WAS IDENTIFIED AT 1531 AND THE INCIDENT WAS IDENTIFIED AS REPORTABLE AT 1632. THE NOTIFICATION WAS MADE AT 1748 TO THE NATIONAL RESPONDER CENTER.
