This temporary completions area of approximately 6.5 acres will be utilized for fresh water storage, produced water storage and completions equipment. We may use up to 60 temporary 500 bbl enclosed tanks and up to 2 MLVTs at this location. MLVTs will be utilized for fresh water storage only. Produced water tanks will have vapor control. The state-licensed manufacturer for the subject site will either be MWS or Pinnacle Manufacturing. The tanks will hold between 40,000-42,000 barrels, are between 153’-158’ in diameter, and plan to be on location for from September 2017 through December 2017 or until completions operations are done. Once completions operations are done, this area will be reclaimed per Final Reclamation BMP. Crestone certifies that the MLVTs are designed and implemented consistent with the June 13, 2014 “Policy on the Use of Modular Large Volume Tanks in Colorado.”

Temporary flowback flaring and oxidizing equipment will include adequately sized equipment to handle 1.5 times the largest flowback volume of gas experienced in a ten mile radius. If there is overrun, Crestone will shut in or choke back the well versus freely venting.
Final Reclamation

The final reclamation plan has been coordinated with staff at CDPHE, COGCC and the surface owner. The proposed plan for reclamation of the temporary completions area is as follows: Reclamation of the site will use onsite, existing fill dirt to spread outward from the pad. No heavy equipment is approved to encroach upon undisturbed land. Toward the northern portion of the TCA, approximately 1-2 feet of existing fill dirt will be left in Area 1 of the attachment diagram. In Area 2 of the attached diagram, approximately 1 foot of existing fill dirt will be spread evenly. Outlying contours will be filled with existing fill dirt; any excess fill dirt will be hauled off. Top soil will then be spread over the newly created area and seeded. Dirt estimates would be approximately 6-12 inches of certified top soil placed directly over the fill dirt for direct seed germination. Reclamation standards will be followed according to the COGCC 1000 Series Reclamation Rules. If trash is encountered on any level, Crestone Peak will contact CDPHE immediately.

Noise mitigation

Crestone has performed baseline noise surveys at the Pratt 29H-P168 (facility ID: 434526) and the Waste Connections 29H-M168 (facility ID: 434375) locations to determine existing ambient noise conditions. These surveys will also serve as the baseline ambient noise survey for the proposed Pratt 29H-P168 TCA given their close proximity. To address noise concerns during operations, Crestone will utilize continuous noise monitoring to assure compliance of COGCC Rule 802. Should Crestone receive any noise complaints during operational activities, sound levels will be measured at a distance of three hundred and fifty feet from the noise source or sound levels will be measured at a point twenty-five (25) feet from the structure towards the noise source. In situations where measurement of noise levels at three hundred and fifty (350) feet is impractical or unrepresentative due to topography, the measurement may be taken at a lesser distance and extrapolated to a 350-foot equivalent using the formula stated in Rule 802 of the State of Colorado Oil and Gas Conservation Commission. As necessary, based on the survey, Crestone will install temporary sound walls to minimize noise and light impacts prior to completions activities.

Crestone will comply with COGCC Rule 1002.f.(2). by utilizing BMPs at the oil and gas location to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, site degradation and protects surface waters.
