Narrative
On 06/07/2013, a release occurred at trinity station. The release was from a pressure alert valve (pav) on the outgoing scraper trap. The incident was investigated which resulted in a determination that the most likely cause was the inadvertent bumpimg of the pav's t handle by contractors conducting capital project work "construction" in the facility. The t handle was modified on 10/25/2013, now requiring the use of a wrench to open ad close the valve.
