Narrative
The release was spotted by a company employee, who followed company procedure for responding and reporting an aoc. Upstream and downstream valves were lo/to to isolate the section of line. All safety precautions were taken. A pipe clamp was used to stop the release, until pipe could be replaced. Contaminated soil was hauled to the wyoming refinery company pcs pad, cost are reflected in part d. Environmental reported 5cu. Yds. Of soil excavation, the oil spill slightly pooled up near the leak location but ran down hill approximately 30 ft. The depth of free-standing oil in the deepest pool location is approximately 1". Taking into consideration the surface area of the spill and a 5% per foot of free standing oil for soil permeation approximately a 0.5 bbl of oil was released as a result of the leak. Excavation of contaminated soil is estimated to have recovered 100% of the product given the insignificant vapor pressure of crude at ambient conditions and no loss to evaporation. The contaminated soil was easily identifiable in the open space in the location of the leak. Weather was mostly cloudy 56�, wind n at 13mph. Reseeding of the dig sight has been completed, sight will be checked in the spring for growth.
