Narrative
An o-ring within the station discharge emergency shutdown valve failed. This failure allowed product vapors to migrate to a non-pressurized section of the valve operator. The pressure within this valve operator housing increased to the point that it forced the valve position indicator switch to separate from the valve operator housing. This separation left an opening on the valve operator housing from which the product vapors were released in to the atmosphere. 11/03/2010: this narrative was updated per discussions with PHMSA-sw representative. 03/04/2013: PHMSA representative requested to modify part e, item 5f, to indicated ">20% smys regulated trunkline/transmission". Phmsa system was modified and to allow for this entry where prior to this change this line item was not required. 07/06/2015: in reviewing historical reports determine that this report was previously submitted as final on 11/03/2010, but per PHMSA's 03/04/2013 request the updated report was submitted as "supplemental" when it should have been submitted as "supplemental/final" this 07/06/2015 update closes this report with the following changes being made: 1.) the chronological date outline of this narrative explaining the changes. 2.) while updating this 7/06/2015 report to close it as "supplemental/final" PHMSA's system required change to part a, item 6, to indicate "nrc notification not required"
