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. 400919088 400919088 FORM 19 SUBMITTED 400919088.pdf 400919088 400939638 ANALYTICAL RESULTS J60623-1 UDS Level 2 Report Final Report.pdf 843022 400919088 1 SPILL 2015-10-08T00:00:00-06:00 COGCC John Axelson
