Narrative
On the evening of august 5, 2018, an unknown member of the public made a 911 call of diesel seeping through street cracks on the corner of hillcrest and sunset avenues. Contra costa county fire department arrived on site and notified the local control center at 19:20 using contact information they saw on the adjacent line marker. The line was immediately shut down and local operations arrived on site at 19:58 and mainline isolation valves were closed shortly thereafter. The road was excavated and a 9' section of the line containing a welded reinforcement sleeve on it was cut and removed. The total volume released from this accident is unknown at the time of this report submission, however, 72 bbls has been recovered to date. Supplemental/final update 2/27/19: metallurgical testing revealed that cracks had formed in the upper fillet weld of the 3 o'clock lap bar of the b sleeve that was installed in 1999. When the cracks that had formed in the carrier pipe (as a result of the initial 3rd party damage) grew to the point of failure, the b sleeve subsequently experienced an instantaneous failure due to the reduction in tensile strength because of these cracks in the upper fillet weld when it became exposed for the first time to the pressure of the diesel.
