THE TOL 5 PUMP WAS SHUT DOWN AND THE TOL5 PUMP STATION WAS ISOLATED FROM THE PIPELINE. THE CONTROLLER RESPONDED TO THE ALARM AND MONITORED FOR FURTHER INFORMATION. THE CONTROLLER NOTIFIED THE FIELD SUPERVISOR AND TECHNICIAN TO INVESTIGATE THE LOCKOUT CONDITIONS. UPON ARRIVAL AT TOL5, THE TECHNICIAN OBSERVED A VAPOR RELEASE AT THE AREA NEAR THE TOP OF THE PUMP. EMERGENCY RESPONSE WAS INITIATED. ETHANE/VAPORS WERE SAFELY CLEARED AND A TRANSITION TO MAINTENANCE/REPAIR STATUS WAS MADE ON 6/15/2015.
