The Produced water did leave location and ran offsite to the east flowing into a landowner pond going past the pond ending in a dry arroyo. The pond and arroyo were considered waters of the state and a call was made to the CDPHE Hotline. The well was turned off until the pit level can be lowerd to below freeboard. It is estimated the 15bbls of produced water were spilled. 400981126 true 2016-01-29T00:00:00-07:00 37.240670 -104.764430 FEE 1 0 0 true <_x0032_7_approved>false S false 0 0 >=5 and <100 0 0 true false true false false 0 2016-01-30T09:55:52.517-07:00 400984162 Produced water quality data from the well associated with or representative of the spill is attached. Pioneer and its consulting geochemical specialists have found, after 20 years operating in the Raton Basin CBM field, that soil sampling no longer adds useful data on smaller, short-term spills as land uses and the environment are not sensitive to short-term exposure to CBM produced water. Effects to soil chemistry from short-term CBM produced water spills are temporary and shallow for several reasons: the water does not contain crude oil or liquid hydrocarbons; the TDS is significantly less than 10,000 mg/L; it is suitable for livestock watering, wildlife and in many cases surface discharge. Mixed with other water it is suitable for irrigation without impact. When requested by the agency or landowner Pioneer has and will collect soil samples. Pioneer Natural Resources request closure of this spill based on this statement and attached water quality data. Soil samples have been requested and will be supplied as I recieve them 400984162 400984162 FORM 19 SUBMITTED 400984162.pdf 400984162 400984209 ANALYTICAL RESULTS Hill 33-22 water quality - 2012-12-19.pdf 79163 400984162 1 SPILL 2016-01-29T00:00:00-07:00 COGCC Jason Kosola

The well was down when the changes were made and when the operator returned the well had pumped up and overflowed the pit. The Pipe to the pit was disconected and there are plans to disable and/or label the burried pipes on location. Soil samples of the spill path have been requested and will be supplied to the COGCC when recieved. 0 0 0 0 15 0 0 0 0 0 false false 0 0 false false false false false false false false true true false true 635 1 0 400984162 1 2016-02-04T00:00:00-07:00 true false false false Lack of training or competance was determined as root cause. the Lease operator was new to this rout and the pipe configuration on the location was not clearly comunicated to him The pipe going to the pit was disconected and will be disabled and/or lebled as to were pipes go. false false false Thread was being aborted.
