A weld on an above ground frac water supply line was compromised resulting in an estimated 5bbls of frac water to migrate along a roadside bar ditch, pooling in a stormwater catch basin. The impacted area will be sampled to determine if remediation is necessary. 440180 400742430 true 2014-11-29T00:00:00-07:00 39.483292 -107.993448 FEE 0 0 0 false <_x0032_7_approved>false S false 0 0 0 0 0 true false false true false >=5 and <100 2014-11-30T12:16:14.627-07:00 Frac Water 400747216 400747216 FORM 19 SUBMITTED 400747216.pdf 400747216 400747876 AERIAL PHOTOGRAPH Cottonwood Tank Farm Form 19 Map 12-4-14.pdf 1551591 400747216 1 SPILL 2014-11-30T00:00:00-07:00 COGCC Stan Spencer

Potts-Ildefonso complex - Stony to very stony clay loam 100 3 1575 147 3400 A weld on a surface HDPE frac water supply line failed. This allowed frac water to flow out onto the ground surface and migrate along the access road bar ditch and into a storm water catchment basin. When the release was discovered, water management personnel halted the water transfer and drained the line to prevent any further fluid loss. The compromised weld was removed and replaced with a new section of pipe. A majority of the release infiltrated into the access road bar ditch due to the dry soil conditions. The remaining volume of fluids lost were contained within the stormwater catchment basin located approximately 376 feet to the south of the Cottonwood tank farm. The impacted soils at the point of origin and two locations along the access road bar ditch were sampled for the entire Table 910-1 analytical suite. Stormwater that was accumulated in the catchment basin was sampled for 910-1. Results were below Table 910-1 standards with the exception of benzo(a)pyrene at the midpoint and terminus of the access road bar ditch and SAR at all three sample locations. The areas exceeding table 910-1 standards for benzo(a)pyrene will be resampled when the soils have had a chance to dry out. Any additional remedial actions, if warranted, will be based on these results. The lease road is sprayed with magnesium chloride solution for dust suppression which results in elevated salt concentrations in the road bar ditch and the stormwater catchment basin. It may not be possible or practical to remediate salt concentrations to 910-1 standards or background. The water analytical results collected from the stormwater catchment basin exhibited very low concentrations of hydrocarbons that do not exceed any regulatory standards. However, approximately 80 barrels of stormwater fluid was recovered from the basin. 0 0 0 0 0 0 0 0 0 0 false false 20 80 false false false false false false false false true true false true 1280 135 frac water 3 400747216 1 2014-12-08T00:00:00-07:00 false true false false A weld on a surface HDPE frac water supply line failed. This allowed frac water to flow out onto the ground surface and migrate along the access road bar ditch and into a storm water catchment basin. The frac water supply lines are pressure tested to 120% of anticipated maximum working pressure prior to operations. All lines are monitored per service provider's BMPs/SOPs, including walking the lines and visual inspection for leaks. WPX SOPs were followed in this case and this incident reinforced the importance of implementing both pre-startup SOPs as well as operational SOPs once work begins. false false false Thread was being aborted.
