2013-11-13		discharge hose
Cause: On November 13, 2013, a release of brine (produced) water occurred at Motiva's Salt Dome Storage Facility in Sorrento, Louisiana. At the time of the release, brine water was being pumped from the South Pit to the North Pit when the discharge hose began spraying produced water onto the ground surface just outside of the brine pits. Initial verbal notification indicates that release was the result of a hose malfunction. The incident was initially reported as a potential exceedance of the 1 barrel reportable quantity for produced water. However, after further calculation, the total amount released during this incident was determined to be below the 1 barrel reportable quantity.

Followup: No

Notes: Upon discovery, operations personnel immediately shut down the pump which stopped the leak.
