A quarter size hole present on the bottom of the tank from what appears to be from corrosion was the cause of the release. The release was discovered when crews noticed liquids present around the front and rear berms of the secondary containment. After the liquids were identified, operations were stopped and hydro vac trucks were dispatched to remove all free liquids within the containment, as well as the remaining liquids within the tank. All free standing liquids were removed from within the secondary containment. The underlying soils will be evaluated for impacts and possible remediation once operations are completed and the tanks are removed. The tank with the hole was removed from service and will either be replaced or repaired. 416722 400779577 true 2015-01-23T00:00:00-07:00 39.531054 -107.608143 FEE 0 0 0 false <_x0032_7_approved>false S false 0 0 >=5 and <100 0 0 true false false true false 0 2015-01-24T08:49:52.03-07:00 40 bbls 400784255 Please review to Carlos Lujan for review 400784255 400784255 FORM 19 SUBMITTED 400784255.pdf 400784255 400784275 TOPOGRAPHIC MAP McLin B Form 19 Map 1-23-15.pdf 1252054 400784255 1 SPILL 2015-01-23T00:00:00-07:00 Landowner

Any additional impacts to the soils under the tank system will be evaluated when flowback operations are completed and the tanks have been removed and the soils have been allowed to dry. 0 0 0 0 40 40 0 0 0 0 0 false false 0 0 false false false false false false false false false false false false 50 40 2 400784255 1 2015-01-30T00:00:00-07:00 false true false false A quarter size hole had corroded away on the bottom of the frac tank, allow the liquids to drain out onto the pad and mix with snow present.
