INTEROFFICE MEMORANDUM TO: GAGLC nIING CO LIB. ~I1.C, C-1981-044 FROM: JANI~; I'BIN \ i SUBJECT: OIL PIPIT .INP: 1 l'UR .AND SPII,I. DATE: 3/13/2007 CC: UAN HERNANUI:% Jerry Nettleton called me on Monday, March 12, 2007, at 9:40 am. He was reporting that an oil pipeline on the Eagle Mine Complex property had ruptured and oil had flowed under Highway 13, through a culvert, at the south end of the Eagle Permit area. He had been notified by the pipeline company, Rocky Mountain Pipeline Company. He was on his way out the door to go observe the spill himself. 3/13/2007: I called Jerry to find out more details regarding the oil spill. He said that the pipeline company informed him tha[ the leak in the pipeline occurred about 7:30 pm Sunday March 11, 2007. The pipeline was formerly owned by Amoco, but is currently owned and maintained by Rocky Mountain Pipeline Company (RMPC). The pipeline carries a light crude oil at 2000 psi. RMPC believed that a portion of the pipeline had become exposed due to weathering, and natural freeze thaw caused a rock to fall on the exposed portion of the line and cause a rupture. RMPC detected the leak remotely and shut ofE the flow to the segment of pipe. A crew Exom the RMPC reported to the area within'/z an hour of detection. Jerry estimated that oil sprayed at high pressure from the line until it was shut off, spraying an area of approximately 3 acres. The location of the spill in TSN, R91W, SWl/4 section 6. Jerry's description of the area is a rocky south-facing drainage. RMPC had brought a backhoe and had dammed and boomed the spill the keep any oil from getting to the Williams Fork River. Crews were hand shoveling contaminated spoIl into barrels and were planning to remove the contaminated soils to a land farm located offsite (near Isles Grove). RMPC was also considering in situ land farming. Jerry was not in Eavor of in situ land farm. I mentioned that I believe that a land farm would need to be permitted with Moffat County and the Colorado Department of Public Health and Environment. Vegetation that has been sprayed with oil will be cleared and grabbed and chipped. A consultant was working with RIvIPC and DOW to clean up the spill appropriately. Jerry will supply RMPC with a seed mix list of appropriate species to put back. I told Jerry that a description of the event and the subsequent clean up will need to be included in the permit This probably could be handled via an MR. Inclusion of the events into the permit will document what happened and who is liable. The permit needs to have an updated ownership of the pipeline is it is no longer Amoco. Jerry agreed with submittal of a revision. RMPC will need to have a final plan of how to manage the clean up pE the spill.
