Narrative
On 12/6/2024 at approximately 11:00, a local landowner notified gulf south area manager that there was a potential leak on the bistineau well b-10 line designated index 901-8. Operations personnel confirmed a leak on the pipeline. The line segment was isolated and fully depressurized. A pipe replacement is in progress. A supplemental report will be submitted once repairs are made and repair cost is calculated. The response to a7 is .1 mcf because it is the minimum reportable amount allowed by the PHMSA portal; the amount was too small to measure. The response to c3, pipe body, is speculated until excavation occurs and it can be confirmed or corrected. 1/29/25 updated to submit final report. Repair was completed by pipe replacement. The pipeline was returned to service on 12/19/2024. 3/13/2025 updated per PHMSA request to change the response for question a14 (part of system involved in incident) from "belowground storage, including associated equipment and piping" to "onshore pipeline, including valve sites," and provide response to additional questions resulting from the change.
