Narrative
At 13:30 on july 26th, 2024 operations personnel at the fargo terminal observed diesel dripping from the prover slide gate which had been worked on the previous day. The release source was isolated and clean-up activities were initiated. Further investigation could not determine the root cause therefore the weamco slide gate was replaced and sent to the manufacturer for failure analysis. A supplemental/final report will follow once the final failure report is received. Supplemental- following an inspection of the weamco gate, the hydraulic ram was identified as the source of the leak. The ram was sent to a 3rd party for assessment. Following the testing and analysis performed by the 3rd party, the decision was made not to send this off for failure analysis but rather to have the 3rd party rebuild and qc test the component. A new hydraulic ram was installed, and the rebuilt unit has been placed in reserve for future use.
