| Cause of Emission Event or Excess Opacity Event, or Reason for Scheduled Activity: |
| 9001 Line O_Maypearl-Handley Old Ocean Pipeline Segment. The release was due to icing in the control/supply lines to the regulation valves, causing the regulator to open causing a high pressure event, and the relief valve did as designed and released gas to protect downstream equipment. |
| Actions Taken, or Being Taken, to Minimize Emissions And/or Correct the Situation: |
| Reduced pipeline pressure to minimize emissions. Repairs to valve were expedited. |
| Basis Used to Determine Quantities and Any Additional Information Necessary to Evaluate the Event: |
| Process knowledge and engineering calculations. |
