Immediate measures were taken to isolate line, stop flow and prevent surface flow of release from reaching the creek. Produced water was drawn out of the vault and remaining static volume in line was removed at injection facility, C17OU. No surface flow of the release reached the creek. Sampling of soils in affected area is being done. 400928465 true 2015-10-30T00:00:00-06:00 39.390552 -108.061925 FEE Encana 1 0 1 false <_x0032_7_approved>false S false 0 0 >=100 0 0 true false false false true 0 2015-10-31T11:24:52.327-06:00 TBD. 400933604 Attn: Carlos Lujan Form 19 Supplemental A Form 27 is being drafted and will be submitted when complete. 400933604 400933604 FORM 19 SUBMITTED 400933604.pdf 400933604 400933605 TOPOGRAPHIC MAP High Mesa to Wallace Creek PL release_TOPOmap_20151031.pdf 1418647 400933604 400933606 ANALYTICAL RESULTS L798254.pdf 1452850 400933604 400933607 ANALYTICAL RESULTS L798259.pdf 790256 400933604 400933608 ANALYTICAL RESULTS PK36 - Orchard 12 inch Lab Summary.pdf 21543 400933604 1 SPILL 2015-10-30T00:00:00-06:00 NRC Antony Greer

Water samples were also collected from the creek and at the down gradient landowners water supply. Potts-Ildefonso complex 12 to 25 percent slopes. Classified as a well drained high runoff soil. Does not have a frequency of flooding or ponding. Release area was very sandy and clay packed to begin, then the release traveled into a sandy/rocky dry drainage. 10 0 2790 20 1500 3488 Initial sampling of release complete. Release will be converted to a Form 27 after the most feasible and econmical approach is selected. After Form 27 is complete and approved; work will proceed. 0 0 0 0 537 480 0 0 0 0 20 false false 0 0 false false false false false false false false true false false false 800 10 0 Thread was being aborted.
