Narrative
Producer had issues with pressure control which allowed a swing in the pressure coming into the texas gas meter station; this caused the relief valve to operate. The relief valve operated property and protected the texas gas equipment from any over-pressuring events. This is a receipt point to texas gas. The system upset was on the producer's assets. Texas gas reported the incident because it was our relief valve that vented the gas. The relief valve operated as designed. 12-4-17 created supplemental to revise per PHMSA instruction.
