The spill ran down the lease road for about 225' were it left the access road and entered a dry drainage that was considerd waters of the state with no live water.Plans for repair are being made with investigation to follow. A call was made to the CDPHE hotline, and for referance the spill occured at the intersection of Cool Whip 22-29 well site. 427440 400902883 true 2015-09-18T00:00:00-06:00 37.322264 -104.701090 FEE Trust Land 1 0 0 true <_x0032_7_approved>false S false 0 0 0 0 0 true false false true false 0 2015-09-21T19:22:17.22-06:00 5bbls 400905336 Repairs to line have been made but is not back in service as of yet, plans to install a gasbuster on lateral are being made and presure testing of line will ocur after this is complete. Have atached Lab report for the well loctaions on this gahtering line.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. 400905336 400905336 FORM 19 SUBMITTED 400905336.pdf 400905336 400935443 ANALYTICAL RESULTS LF@3719920|400935443 665329 400905336 1 SPILL 2015-09-21T00:00:00-06:00 CGCC John Axelson
