Hazardous liquid gravity and reporting-regulated-only incident in Not Within a Municipality, DIMMIT County, TX. Reported cause: CORROSION FAILURE. Reported consequences: 0 fatalities, 0 injuries, 40 CRUDE OIL released, $13,400 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: 20230042.

Operator ID: 300.

Reported incident date: 4/12/2023 19:00.

Cause detail: EXTERNAL CORROSION

Cause detail: APPROXIMATELY 40 BARRELS OF CRUDE OIL WERE RELEASED FROM THE SM BRISCOE CATARINA 4INCH PIPELINE. THE DATE AND TIME OF THE RELEASE (PART A Q4) IS INDICATIVE OF THE EARLIEST POSSIBLE TIME THE RELEASE COULD HAVE STARTED BASED ON PUMP DATA. THE CAUSE OF THE RELEASE IS ATTRIBUTED TO EXTERNAL CORROSION, AND TO PREVENT FUTURE RELEASES, THE LINE WAS CUT-OUT AND REPLACED. ADDITIONALLY, A DIRECT CURRENT VOLTAGE GRADIENT (DCVG) SURVEY WAS PERFORMED TO EVALUATE THE EFFECTIVENESS OF THE CATHODIC PROTECTION PROGRAM. SUPPLEMENTAL: UPDATES APPLIED TO THE VOLUME RECOVERED AND THE DATE/TIME OF NOTIFICATION TO THE TEXAS RAILROAD COMMISSION.
