A production unit had a needle valve on a choke cap suffer sand erosion to the point of failure. The compromised cap/valve allowed produced water to release from the piping. The flow was shut off to the unit to ensure there was not any further fluid loss before the cap could be replaced. The impact of the released liquid was limited to the working surface of the location and no waterway of the US were impacted. 335903 400597258 N true 2014-04-26T00:00:00-06:00 39.518308 -108.248709 OTHER (SPECIFY) Oxy-Private 0 0 0 true <_x0032_7_approved>false S false Rangeland 0 0 >=1 and <5 0 0 false true false true false 0 2014-04-28T11:19:25.627-06:00 400953895 400953895 FORM 19 SUBMITTED 400953895.pdf 400953895 400953903 ANALYTICAL RESULTS Sample data tabulation.pdf 5359 400953895 400953905 AERIAL PHOTOGRAPH 697-17-50 spill sample location map.pdf 601506 400953895 400953908 ANALYTICAL RESULTS 1503873 (Oxy) 697-17-50 Spill Revised Report.pdf 356625 400953895 400953909 ANALYTICAL RESULTS L696375.pdf 36340 400953895 400802626 19 Supplemental Form 19 spill report 400953895 1 SPILL 2014-04-26T00:00:00-06:00 COGCC Carlos Lujan

Utso-Rock outcrop complex, 40-90% slopes (map unit symbol 71). During excavation, native shaley soil was encountered throughout the excavation profile. 80 2 600 680 680 Oxy collected two surficial soil samples from within the spill path area following receipt of Agency comments found in document # 400802626. Oxy collected two grab samples to characterize potential existing impacts associated with the spill. Based on the laboratory analytical results provided in the attached documentation, no impacts exist as no analytical concentrations exceed COGCC Table 910-1 standards. Oxy requests to close this spill as no analytical results exceed COGCC Table 910-1 standards. 0 0 0 0 3 0 0 0 0 0 3120 false false 0 0 false false false false false false false false false true true false 25 25 Thread was being aborted.
