Accident Classified As:

Cause of Problem: Piping or Tubing

oil/water mixture discovered leaking from above ground pipeline--out-of-service tank water draw line. Mixture migrated in an earthen (diked) pipeway 800' east and stopped. Heavy rains occurred a few days into cleanup, flooding contained area where spill occurred. No DEQ report in this file, follow-up letter only.

Discharge Preventable - No

"The external area of the piping around the failure was in very good condition with no notable corrosion present. The incident appears to be the result of internal corrosion of the pipeline which was not expected due to the line being out-of-service."

Notes/Remedial Actions

Clamped leak. Four vacuum trucks dispatched to remove free liquid, brought to Motiva's recovered oil sump for reprocessing in the refinery. Contaminated soil excavated and placed into plastic bags for disposal. Will add "Micro-Sorb(tm)" to the ground to further promote biodegradation of any low-level residual hydrocarbons once area dries out after the heavy rains. Will flush line then blind and isolate it.
