Reported consequences: 0 fatalities, 0 injuries, 18000 NATURAL GAS released, $0 reported property damage. Operator-reported incident data submitted to PHMSA, generally within 30 days. Records may be supplemented or corrected and do not represent final agency causal findings. Report number: 20160073. Operator ID: 2748. Reported incident date: 8/10/2016 23:32. Location detail: GV-007 Cause detail: OTHER INCORRECT OPERATION Cause detail: ON AUGUST 10, 2016 AT APPROXIMATELY 22:43 CONSUMERS ENERGY RAY COMPRESSOR STATION EXPERIENCED AN EVENT WHEREBY POWER SUPPLIED BY THE UTILITY SUPPLIER WAS BELOW NORMAL LEVELS. THE CONTROL SYSTEM RECOGNIZED A UTILITY SOURCE PHASE SEQUENCE LOSS AS WELL AS A STATION UNINTERRUPTIBLE POWER SUPPLY (UPS) ALARM. AT APPROXIMATELY 22:44, THE COMMERCIAL UTILITY BREAKERS TRIPPED OPEN AND PLANT 3 EMERGENCY SYSTEM TRANSFERRED POWER FROM THE UTILITY OVER TO GENERATOR 3-00-01. THE SYSTEM ATTEMPTED TO TRANSFER POWER TO THE C2-7 GENERATOR SET FOR PLANTS 1 AND 2; HOWEVER, THE SYSTEM DID NOT START AND PLANTS 1, 2 AND THE CONTROL ROOM REMAINED ON UPS POWER. AT APPROXIMATELY 22:44, UTILITY POWER AT THE STATION WAS RESTORED TO ACCEPTABLE LEVELS ACROSS ALL THREE LEGS, AB, BC AND CA. PLANT 3 TRANSFERRED BACK TO UTILITY POWER, HOWEVER, PLANT 1, 2 AND THE CONTROL ROOM REMAINED ON UPS POWER. AT APPROXIMATELY 22:52, UNIT 2-7 INITIATED IT'S SHUTDOWN SEQUENCE DUE TO HIGH CRANKCASE OIL TEMPERATURE, HIGH JACKET WATER TEMPERATURE, LOW ENGINE LUBE OIL PRESSURE AND LOW TURBOCHARGER OIL PRESSURE ALARMS. AT APPROXIMATELY 23:32 THE 2-7 UPS WAS DEPLETED WHICH SUPPLIED POWER TO VENT VALVE GV-007. VENT VALVE GV-007 FAILED OPEN, AS DESIGNED IN THE EVENT OF A POWER LOSS, RESULTING IN A RELEASE OF NATURAL GAS INTO THE ATMOSPHERE. THE ON-CALL OPERATOR ARRIVED AT THE LOCATION ON AUGUST 11, 2016 AT APPROXIMATELY 00:06. AT APPROXIMATELY 00:14 THE ON-CALL OPERATOR REPORTED VENTING GAS AT THE THE SOUTHWEST CORNER OF THE PLANT, VALIDATED THE VENTING GAS WAS COMING FROM PLANT 2 AT APPROXIMATELY 00:20. AT APPROXIMATELY 00:28 A PLANT 2 FIREGATE OPERATION WAS INITIATED AND VENTING GAS WAS STOPPED AT APPROXIMATELY 00:33. THE ON-SITE TEAM BEGAN INVESTIGATING THE CAUSE OF THE VENT VALVE OPENING AND GATHERING DATA. IT WAS DETERMINED THAT GENERATOR 2-7 CONTROL PANEL WAS IN THE "OFF" POSITION. THE CONTROL PANEL IN THE "OFF" POSITION PREVENTS AUTOMATIC OPERATION OF THE UNIT. ON AUGUST 11, 2016 AFTER COMPLETING THE INVESTIGATION, PLANT 2 WAS PLACED BACK INTO SERVICE AT APPROXIMATELY 16:00. PHMSA trend classification: significant incident, not serious. PHMSA standardized cause: INCORRECT OPERATION — OTHER INCORRECT OPERATION. PHMSA indexed costs: $56,218 reported total cost, $58,720.452 in 1984 dollars, $73,328.574 in current-year dollars. PHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings. ## Provenance - Official: Yes - Source: - Source ID: `phmsa-pipeline-incidents` - SHA-256: `b0d7b49ff37038d9333dc7f582492749a427071d69be475c1c5847abe09b913c` - Retrieved: 2026-08-20T03:30:32.010Z - Exported: 2026-08-26T04:56:21.970Z - Document slug: `phmsa-incident-7ef4106c567736e2e6cd4f60` ### Source metadata ```json { "recordKind": "pipeline_incident", "datasetType": "gas_transmission_gathering", "datasetLabel": "Gas transmission and gathering", "datasetPeriod": "January 2010 to present", "report": { "number": "20160073", "supplementalNumber": "17225", "type": "SUPPLEMENTAL FINAL", "receivedDate": "2016-09-09", "receivedDateRaw": "9/9/2016" }, "operator": { "id": "2748", "name": "CONSUMERS ENERGY CO" }, "incident": { "date": "2016-08-10", "dateRaw": "8/10/2016 23:32" }, "location": { "city": "ARMADA", "county": "MACOMB", "state": "MI", "postalCode": "48005", "latitude": 42.809207, "longitude": -82.864825, "type": "OPERATOR-CONTROLLED PROPERTY", "details": { "DESIGNATED_NAME": "GV-007" }, "facilityName": "RAY COMPRESSOR STATION" }, "cause": { "category": "INCORRECT OPERATION", "details": { "CAUSE_DETAILS": "OTHER INCORRECT OPERATION", "NARRATIVE": "ON AUGUST 10, 2016 AT APPROXIMATELY 22:43 CONSUMERS ENERGY RAY COMPRESSOR STATION EXPERIENCED AN EVENT WHEREBY POWER SUPPLIED BY THE UTILITY SUPPLIER WAS BELOW NORMAL LEVELS.
