Budd 24-33 well site. The Lease Operator found a break in the gathering line on the access road to the site. The leak was isolated immediately and is being prepped for repair. The leak ran down the lease road to the south entering a meadow then through a culvert headed back north and ended in a dry drainage that was considered Waters of the State with no live water. It is estimated that 400bbls of produced water were spilled. A call was made to the CDPHE Hotline. Water from this spill normally goes to CDPHE permitted outfall #065. The spill occured on the accesss road to the referenced site wich is in a different section and QTRQTR than the well site. 427440 400995679 true 2016-02-24T00:00:00-07:00 37.295940 -104.688220 FEE 1 0 0 true <_x0032_7_approved>false S false 0 0 >=100 0 0 true false false true false 0 2016-02-25T09:06:12.03-07:00 400999498 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. As requested PNR has had our Third party consultant collect soil samples of the spill path. They were collected on Tuesday March 1st. The results of the soil samples will be given as I recieve them form the Lab. Pioneer Natural Resources request closure of this spill based on this statement and attached water quality data (for CDPHE permited outfall #065) and review of soil sample results when submited. 400999498 400999498 FORM 19 SUBMITTED 400999498.pdf 400999498 400999526 ANALYTICAL RESULTS Polly 065A Water Quality - 2015-12-22.pdf 53794 400999498 1 SPILL 2016-02-24T00:00:00-07:00 COGCC Jason Kosola
