Once discovered, the operator shut off the dump line from the demethanizer to the NGL storage tank, stopping liquid from passing into the 1’’ line. The operator also shut off all check valves to isolate the damaged piping. The release is estimated at approximately 1 bbl of NGL that evaporated once released. COGCC was notified by phone at 11:15 on May 6, 2015. On May 7, 2015 at 8:00 am a backhoe is scheduled onsite to excavate and replace the line. 255945 400836584 true 2015-05-06T00:00:00-06:00 37.436710 -108.910660 FEDERAL 0 0 0 true <_x0032_7_approved>false S false On-site release Unknown 0 0 0 0 false false false true false 0 2015-05-06T15:47:13.563-06:00 Approximately 1 bbl of NGL . 400846435 400846435 FORM 19 SUBMITTED 400846435.pdf 400846435 400846436 ANALYTICAL RESULTS Rpt_1505365_Final_v1_Sample 1.pdf 155713 400846435 400846438 ANALYTICAL RESULTS Rpt_1505938_Final_v1_Sample 2.pdf 147341 400846435 400846439 OTHER 20150529_BLM_Letter_Reporting and Corrective Actions.pdf 1433558 400846435 400846440 AERIAL PHOTOGRAPH Cutthroat B Gas Plant - Google Earth Image - 06102014.pdf 450077 400846435 1 SPILL 2015-05-06T00:00:00-06:00 BLM Pamela Leschak

Once discovered, the operator shut off the dump line from the demethanizer to the NGL storage tank, stopping liquid from passing into the 1’’ line. The operator also shut off all check valves to isolate the damaged piping. No visible surface NGL release characterization. On May 7, 2015 at 8:00 am a backhoe began excavating the soil around the damaged piping. LT Environemental contractor was onsite and sampled soil from four locations. Piping was left uncovered until results can back. Due to high sampling results a second round of samples was taken on May 19, 2015. (Both sets of analyitical results have been attached to this report.) 1" section of line has been replaced. Per BLM, no further action is required at this time. At such future time there are potential negative impacts associated with this release observed, or when the facility is set for decommissining; site characterization and remediation shall take place.
