Narrative
While conducting an esd test the station vented 3.8 mmscf of natural gas. During a normal esd, it takes some time to blowdown the yard piping after activation of the system. When the blowdown valve continued to blow, operations personnel began to investigate and found the 300 suction side gate valve to still be open. The isolation valve under the blowdown valve was closed. Operations personnel isolated the suction side gate valve, then tested the valve and it operated as designed. Operations personnel tested the esd system and found there was an air leak on the esd tubing. The air leak was repaired and the system was tested.
