APPLICABLE STATE AND FEDERAL AGENCIES WERE CONTACTED. THE LINE(MISSISSIPPI RIVER CROSSING #5) IS CURRENTLY INACTIVE (IDLE). PLANS ARE BEING DEVELOPED TO BORE UNDER THE RIVER AND INSTALL A 24" LINE. THIS PROJECT IS CURRENTLY IN THE BID PROCESS AND SHOULD BE COMPLETED LAST QUARTER OF 2013. THE CAUSE OF THE RELEASE IS A BARGE STRIKING OUR PIPELINE. THE CREW HAVE SINCE BEEN ALERTED TO THE PRESENCE OF PIPELINES IN THE AREA AND PIPELINE SAFETY IS NOW DISCUSSED DURING CREW CHANGE MEETINGS. WE ARE WORKING WITH THE US COAST GUARD TO GET THE AREA BUOYED UNTIL WATER LEVELS RISE. WE PERFORMED A SIDE SCAN SONAR 8/17-8/20. THE RESULTS OF THIS SCAN INDICATED THAT THIS LINE WAS EXPOSED WITHIN 60 FT OF THE WATERS EDGE, BUT NOWHERE ELSE THROUGHOUT THE LINE. PER PHMSA REQUEST, PART C PIPE DATA HAS BEEN UPDATED. ALSO, PART E, PART H, AND PART I HAVE BEEN UPDATED. PLANS ARE BEING DEVELOPED TO BORE UNDER THE MISSISSIPPI RIVER AND INSTALL TWO 16" PIPELINES. THIS PROJECT IS CURRENTLY WAITING ON PERMITS TO BE APPROVED BY THE U.S. ARMY COPRS OF ENGINEERS. THIS PROJECT IS SCHEDULED TO BE COMPLETED BY END OF YEAR 2015.
