Narrative
On 8/23 while patrolling ls-9, the km-stockton line rider noticed a slight stain over the pipeline. He used a shovel to dig down a few inches and noticed a distinct petroleum smell the deeper he dug. The pipeline was shutdown and the pressure was drained into bradshaw, agency notifications were made. Km internal notifications were made and maintenance crews and contract personnel were dispatched to investigate. Excavation revealed contaminated soil down to and below the pipe as well as coating damage. At approximately 1803 a small weep was found on the threads of one of the valve fittings. The valve body was drained and the fittings were removed and replaced temporarily with a pipe plug. The line resumed normal operations at 2107. Personnel from arb remained overnight to provide site security. Subsequent investigation revealed 38 barrels of a mixture of gasoline/diesel/jet fuel released. Approximately half of which was removed via excavation. The remainder will be remediated longer term. The permanent repair was done within the next quarter and included replacement with socket and/or back-welded fittings. Note: part a, #7 we began this call @ 0743 and were informed by nrc to call back @0805 due to a drill they were conducting. A second call was made @ 0805 which was not answered. The third call was initiated @ 0818, but nrc reported it as 0820 pacific time. Note: part a, #9 estimated from dimensions of contamination. Note: part a, #11 was estimated from hydrocarbon concentration of the excavated soils and provided on thesupplemental report. Note: part d, #5 (b) estimate based on shallow depth of groundwater (same as soil calculation) note: part e, #9. We were limited to 500 characters; our entire response is: the performance of a preliminary investigation into the pre-existing condition of the pipeline (I.E. Pressure, flow, line balance, etc.) was shown to provide no evidence of an existing problem the controller(s) should have identified. Furthermore, the actions taken by the controller(s), upon learning of the potential problem from field personnel physically at the valve, were found to be in alignment with the operators written policies and procedures and the timeline of events show that action was taken promptly and decisively thus helping to mitigate any further loss or environmental harm. 1/13/2012 supplement filed because the original estimate (thought to be accurate at time of finalizing) of the remediation costs have increased more than $20,000. Long term remediation will include removal of the source via additional excavation and drilling wells to monitor natural attenuation.
