Incident Narrative

AT APPROXIMATELY O5:30 PLT, OUTSIDE TANK FARM CONTROLLER DISCOVERED A POOL OF GREEN DRAG REDUCING AGENT (DRA) BY THE LINE 20 TRAP AND GREEN DRA BUBBLING UP WHERE THE DRA INJECTION LINE FOR LINE 20 COMES ABOVE GRADE. LINE 20 AND DRA INJECTION WERE SHUT DOWN AND DRA INJECTION ISOLATED. NOTIFICATIONS TO OM, ENVIRONMENTAL SPECIALIST AND DISTRICT PROJECT LEADER, WHO IS ACTING DISTRICT DIRECTOR OF OPERATIONS, WERE MADE. ENVIRONMENTAL SPECIALIST, TECHNICIAN,AND A CONTRACT CREW RESPONDED TO CLEAN UP THE SITE AND DETERMINED THE SOURCE TO BE A FAILURE OF THE DRA HIGH PRESSURE HOSE. APPROXIMATELY 300 SQUARE FOOT AREA WAS IMPACTED ON THE SURFACE WITH DRA/DIESEL FUEL MIXTURE NEAR THE LINE 20 LAUNCHING TRAP. APPROXIMATELY 55 GALLONS OF DRA AND DIESEL MIXTURE WAS RECOVERED OFF THE GROUND USING DIAPHRAGM PUMPS. AN ESTIMATED 125 GALLONS OF THE DRA AND DIESEL MIXTURE WAS CONTAINED WITHIN THE EXCAVATED SOIL. THE SOIL VOLUME WAS BASED ON OBSERVATIONS OF THE EXCAVATED SOIL; LABORATORY ANALYSIS OF THE SOIL WAS NOT MADE DUE TO THE LACK OF APPROPRIATE ANALYTICAL METHODOLOGY FOR THE DRA AND DIESEL MIXTURE. TOTAL RECOVERED MIXTURE WAS 180 GALLONS. IT WAS ESTIMATED THAT 50% OF THE MIXTURE WAS DIESEL FUEL BASED ON VISUAL OBSERVATION. THEREFORE, 90 GALLONS OF DIESEL FUEL WERE RELEASED AND RECOVERED IN TOTAL, AND 90 GALLONS OF DRA WERE RELEASED AND RECOVERED. THERE WERE NO IMPACTS TO GROUNDWATER, AND THERE WERE NO AGENCY NOTIFICATIONS MADE. THE DRA AND DIESEL MIXTURE WAS COMBINED WITH THE CONTAMINATED SOIL AND ADDED SAWDUST FOR SOLIDIFICATION. THE SOLID WILL BE TRANSPORTED TO A LOCAL LANDFILL FOR DISPOSAL. NO FURTHER REMEDIAL ACTION REQUIRED.
