Cause detail: GULF SOUTH'S PIPELINE TECH FOUND A MINOR LEAK DURING LINE PATROL OF ITS INDEX 64. THE LINE IS IN A CREEK EXPOSURE. INDEX 64 IS OPERATING AT 155 PSIG AND HAS A MAOP OF 292 PSIG. THE LEAK IS SMALL AND 700 FT. FROM THE NEAREST STRUCTURE AND HIGHWAY. THE AREA WAS FLAGGED OFF AND CONTACT AT THE NEAREST PROPERTY WAS MADE. GULF SOUTH WILL INVESTIGATE THE LEAK TO DETERMINE WHAT REPAIR METHOD IS NEEDED. A PIPE REPLACEMENT IS THE LIKELY THE BEST REPAIR WHICH WOULD CAUSE THE COST TO EXCEED $50,000, MEETING THE PHMSA DEFINITION FOR INCIDENT. FOR THIS REASON, THE NRC WAS CALLED. THE GAS LOSS REMAINS UNKNOWN, BUT MINIMAL, AT THIS TIME AND THEREFORE, A GAS LOSS COST IS NOT DOCUMENTED IN THIS REPORT. THE RESPONSES TO PART E QUESTIONS 5A, 5B, AND 5C REPRESENT THE ANSWERS THAT WILL BE TRUE WHEN THE SECTION IS ISOLATED AND BLOWN DOWN; THAT HAS NOT YET HAPPENED BUT THE ANSWERS ARE POPULATED BECAUSE THE PORTAL WILL NOT ALLOW SUBMISSION OF THIS REPORT WITHOUT POPULATING THESE FIELDS. 8-21-19 UPDATE TO SUBMIT FINAL REPORT. A PLIDCO BOLT-ON CLAMP WAS INSTALLED. UPDATED REPAIR COSTS ACCORDINGLY. IN RESPONSE TO PHMSA EMAIL DATED 6-18-19, THE DATE SHOWN IN PART A, ITEM 4 (5-15-2019) IS CORRECT. THIS WAS THE DATE THE "POTENTIAL" LEAK WAS FIRST DISCOVERED ALTHOUGH IT WAS NOT A CONFIRMED LEAK NOR YET CONFIRMED WHAT THE REPAIR WOULD BE, THEREFORE, REPAIR COSTS COULD NOT YET BE ESTIMATED.
