Cause detail: AT 11:55 AM ON 12/2/2017, DCP MIDSTREAM'S HOUSTON CONTROL CENTER (HCC) RECEIVED A CALL FROM THE NEIGHBORING TARGA PLANT CONTROL ROOM. THE OPERATOR AT THE TARGA PLANT STATED THAT HE SAW A PRODUCT VAPOR CLOUD BLOWING INSIDE OF THE DCP FACILITY AT THE MONT BELVIEU STATION, ON THEIR CAMERAS. A HCC CONTROLLER NOTIFIED AN NGL TECH OF THE SITUATION WHO THEN PROCEEDED ON SITE TO INVESTIGATE. AROUND 12:19 PM THE NGL TECH WHICH ARRIVED ONSITE, NOTIFIED HCC THAT EVERYTHING WAS UNDER CONTROL AND THE LEAK WHICH OCCURRED ON A SAMPLER SPEED LOOP MOTOR WAS BLOCKED IN AND COMPLETELY ISOLATED. DCP DETERMINED THAT DUE TO EXCESSIVE VIBRATION OF THE PUMP, THE TUBING BROKE OFF. THE PUMP WILL NOW BE BOLTED ONTO THE CONCRETE SLAB TO ALLEVIATE ANY EXCESSIVE VIBRATION. ADDITIONALLY, DCP IS NOW ENGAGED IN CONDUCTING A SITE STUDY TO DETERMINE THE MOST EFFECTIVE PLACE TO LOCATE ITS LEAK DETECTION EQUIPMENT AND FOR ADDING ANY ADDITIONAL EQUIPMENT.
