Rentsac channery loam - slightly to moderately alkaline channery loam 100 0 2737 One of the frac tanks being utilized to store water for flowback operations developed a hole due to corrosion of the metal. This allowed flowback water to migrate out onto the well pad. When the release was discovered flowback personnel diverted the flowback water from the leaking tank into the adjacent tanks. The entire release was contained on the bermed pad surface. The impacted area will be re-assessed once completion operations are complete and the tanks have been removed from the location. A soil sample will be collected and analyzed for the full COGCC Table 910-1 analytical suite. Remedial actions, if warranted will be based on these results. 0 0 0 0 0 0 0 0 10 6 false false 0 0 false false false false false false true false true true true true 143 21 400616328 1 2014-05-29T00:00:00-06:00 false true false false One of the frac tanks being utilized to store water for flowback operations developed a hole due to corrosion of the metal.
