Incident Narrative

THE LEAK WAS CAUSED BY THE SUMP FILLING WITH WATER AND FLOATING THE PRODUCT UP AND OUT OF THE SUMP TANK. THE SUMP IS LOCATED IN A SECONDARY CONTAINMENT AREA ASSOCIATED WITH THE CARROLLTON TANK BOOSTERS. THE TANK BOOSTERS ARE EQUIPPED WITH JO-BELL SEAL LEAK DECTECTION DEVICES. THE HEAVY RAINS FLOODED THE TANK BOOSTER PUMP AND SUMP AREA. THE WATER ENTERED THE SUMP THROUGH THE JO-BELL SEAL LEAK DETECTION DEVICE. AN ALARM WAS RECEIVED BY SINCLAIR'S CONTROL ROOM PERTAINING TO THE ACTIVATION OF THE SEAL LEAK DEVICE AT 09:37 ON 5/27/13. THE BOOSTER PUMPS WERE NOT RUNNING AT THAT TIME SO NO ONE WAS CALLED OUT TO CHECK ON THE ALARM AS PER THE PROCEDURES FOR THESE ALARMS WHEN THE PUMPS ARE NOT RUNNING. THE SUMP IS NOT EQUIPPED WITH A HIGH SUMP ALARM SYSTEM. AT APPROXIMATELY 08:00 ON MAY 28, 2013 THE CARROLLTON STATION OPERATIONS SUPERVISOR WAS CHECKING THE STORMWATER CONTAINMENT AREAS AT CARROLLTON STATION FOLLOWING THE MEMORIAL DAY WEEKEND. THE CARROLLTON AREA HAD RECEIVED NEARLY 5' OF RAIN THAT WEEKEND.
