A PLIDCO REPAIR SLEEVE WAS INSTALLED OVER ISOLATED CORROSION PIT AS A PERMANENT REPAIR. THE LINE WAS RESTARTED ON 04/02/2019 AT 16:28. THE SUBSEQUENT IA DETERMINED THAT THE LIKELY SOURCE OF THE CORROSION WAS ASSOCIATED WITH THREE COMMUNICATIONS LINES THAT CROSSED THE PIPELINE IN CLOSE PROXIMITY TO THE THROUGH-HOLE SITE. THE COATING SURROUNDING THE THROUGH-HOLE WAS FOUND TO BE DISBONDED FOLLOWING THE INCIDENT. THIS DISCONTINUITY IN THE COATING (HOLIDAY) EXPOSES THE PIPELINE TO CORROSIVE EFFECTS FROM OUTSIDE SOURCES. A TOTAL OF 523 TONS OF SOIL WAS REMOVED DURING RESPONSE AND REPAIR EFFORTS. THE SOIL VOLUME CALCULATION GIVES THAT 2603 GALLONS OF PRODUCT WERE RECOVERED IN THE SOIL. DURING THE EMERGENCY RESPONSE EFFORTS AND SUBSEQUENT REMEDIAL VACUUM EXTRACTION EVENTS, A TOTAL OF 422 GALLONS OF FREE PRODUCT HAS BEEN RECOVERED. TOTAL CALCULATED RECOVERY FOR THE SITE IS 3,025 GALLONS. ANY FURTHER PRODUCT RECOVERY OR SOIL REMOVAL ARE PART OF THE LONG-TERM REMEDIATION EFFORTS BEING GOVERNED BY THE STATE OF NORTH CAROLINA'S DEPARTMENT OF ENVIRONMENTAL QUALITY.
