THE HOLLY ENERGY TECHNICIAN DRAINED ENOUGH OF THE CRUDE OUT OF THE STRAINER AND INTO THE SUMP IN ORDER TO STOP THE LEAK. THE CRUDE OIL WAS CONTAINED WITHIN THE CONFINES OF THE PUMP STATION AND STUCK TO THE LAYER OF GRAVEL; THEREFORE, DID NOT PENETRATE THE SOIL (AS IT IS HEAVY CRUDE).

NOTE: I HAVE ATTEMPTED TO COMPLETE PART G ON SEVERAL OCCASIONS AND HAVE NOT BEEN SUCCESSFUL. THE FIELD FOR THE DESCRIPTION FOR ""OTHER EQUIPMENT FAILURE"" WILL NOT ALLOW ME TO TYPE IN IT. THE CAUSE OF THE EQUIPMENT FAILURE WAS DUE TO THERMAL PRESSURE. SUPPLEMENTAL NOTES 03/04/2014: IN ORDER TO CLARIFY HOW THE EQUIPMNET FAILED DUE TO THERMAL PRESSURE WE ARE ADDING ADDITIONAL NOTES TO THIS SUPPLEMENT REPORT.
