Narrative
A leak on enterprise products operating llc 10 inch lou-tex propylene pipeline occurred on october 15, 2010. Enterprise was in the process of running a gauging tool through a portion of the pipeline. While re-pressuring an equalizing pipeline section a 10 inch wkm pigging valve became in operable. While trying to equalize pressure, a 1/2 inch needle valve was opened on the body of the 10 inch valve. This needle valve iced open and would not close releasing product onsite. Local fire water was used to de-ice the needle valve to allow valve to close. Isolation of approximately 5 miles of pipeline was performed so maintenance could be completed on the 10 inch wkm valve. Repaired and returned to service. Revised part e: question number 6.D and number 9.
