Narrative
The products pipeline station is located at the south end of the wrc property. A release was spotted by a refinery employee between the products pipeline prover skid and the number one pipeline pump suction check valve. The employee followed company procedure for responding and reporting an aoc. Upstream and downstream block valves were closed and lo/to to isolate the section of line. All safety precautions were taken to include dispatching the light water unit as well as several fire extinguishers placed around the release site. Pipe was excavated, external corrosion was identified. Pipe was replaced, hydro test was performed, welds were completed and inspected per wpc procedure and qualifications. Contaminated soil was handled according to refinery procedure. It was taken to the pcs pad at the wyoming refinery company, the estimated cost are included in part d. Environmental reported approximately 30 cu. Yds of soil. Commodity released during the spill was non-ethanol gasoline. The dimensions of the apparent spill area were about 10'x15' with approximately 1' of free-standing product in the deepest part of the spill pool. Given the approximate surface area and factoring 5% additional product per foot of free-standing gasoline in soil permeation it is estimated that approximately 0.5 bbl was spilled. Recovery of product in the contaminated soil is estimated to be 0.47 bbl due to evaporation of the product. This factors in that a non-hvl was involved, the initial boiling point of all the components in any gasoline blend such as this are well over 80֯f, and the surface area to air was minimal compared to the volume of spill area excavated. The accident location has multiple inspection walks throughout the day. With the discovery time and product that was on the ground an estimated .03 bbls was lost due to evaporation. Weather was 92�f with a light breeze of 7.9 mph out of the west north west.
