Narrative
25 gallon crude oil release from station suction piping. The cause of the release was internal corrosion. Pipe is being examined by a metallurgist, but results are not available at this time. Update 5/13/15 - a 20 foot spool piece of 20 inch pipe was replaced as a repair as well as to minimize low flow piping. A visual inspection was done on the remaining pipe with no internal corrosion observed. The original report indicating the a metallurgical examination would be done was incorrect, field/visual inspections were conducted by an empco corrosion technician and the cause was determined to be a combination of internal corrosion and erosion. The manifold at the leak location is treated with corrosion inhibitor, and a dna bacteria survey has been completed. Gps coordinates appear to be correct when checked on google earth. A total of 49 tons of soil were removed from the site. Soil disposal costs were higher than original estimates resulting in the total incident costs exceeding $50k. The fact that the total costs had exceeded $50k was not discovered until the original 7000-1 was completed.
