COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
Permit	Form: (02) 400320588 08/31/2012	Operator must meet Water Well Testing requirements as per amended Rule 318Ae(4)
Engineer	Form: (02) 400320588 09/06/2012	1) Submit Form 42 electronically to COGCC 48 hours prior to MIRU. 2) Comply with Rule 317.i and provide cement coverage from TD to a minimum of 200' above Niobrara. Verify coverage with cement bond log. 3) Comply with Rule 321. Run and submit Directional Survey from TD to base of surface casing. Ensure that the wellbore complies with setback requirements in commission orders or rules prior to producing the well.
Engineer	Form: (06) 401277307 05/12/2017	1) Provide 48 hour notice of plugging MIRU via electronic Form 42. 2) For the 738’ plug: pump plug and displace. If surface casing plug is not circulated to surface then tag plug – must be at 538’ or shallower and provide 10 sx plug at the surface. Leave at least 100’ of cement in the casing for each plug. 3) Properly abandon flowlines as per Rule 1103. File electronic Form 42 once abandonment complete. 4) Prior to starting plugging operations a Bradenhead test shall be performed. If the beginning pressure is greater than 25 psi, or if pressure remains at the conclusion of the test, or if any liquids were present contact COGCC Engineering for sampling requirements. The Form 17 shall be submitted within 10 days of the test.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Planning	Form: (02 ) 400320588 9/28/2012	When feasible develop multiple well sites by using directional drilling to reduce cumulative impacts and adverse impacts on wildlife resources.
Construction	Form: (02 ) 400320588 9/28/2012	Remove only the minimum amount of vegetation necessary for the construction of roads and facilities. Conserve topsoil during excavation and reuse as cover on disturbed areas to facilitate regrowth of vegetation .No construction or routine maintenance activities will be performed during periods when the soil is too wet to adequately support construction equipment.
Site Specific	Form: (02 ) 400320588 9/28/2012	Fence the well site after drilling to restrict public and wildlife access. Keep well site location, the road, and the pipeline easement free of noxious weeds, litter and debris. Spray for noxious weeds, and implement dust control, as needed. Sundance Energy Inc., will not permit the release or discharge of any toxic or hazardous chemicals or wastes on Owner’s Land. Construct and maintain gates where any roads used by Sundance Energy Inc., its employees, or contractors cross through fences on the leased premises.
Drilling/Completion Operations	Form: (02 ) 400320588 9/28/2012	When available and reasonable use a closed-loop drilling mud system to preclude the use of an earthen reserve pits when available.
Storm Water/Erosion Control	Form: (02 ) 400320588 9/28/2012	Use water bars, and other measures to prevent erosion and non-source pollution. Implement and maintain BMPs to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation. Co-locate gas and water gathering lines whenever feasible, and mitigate any erosion problems that arise due to the construction of any pipeline(s).
Interim Reclamation	Form: (02 ) 400320588 9/28/2012	Utilize only such area around each producing well as is reasonably necessary. Restore the remainder of the well site location to its original condition within a reasonable time after the completion of operations. All reseeding shall be done with grasses consistent with the Rocky Mountain native mix or other grasses reasonably requested by surface owner and during planting period suggested by Owner.
Final Reclamation	Form: (02 ) 400320588 9/28/2012	All surface restoration shall be accomplished to the satisfaction of Owner. All reseeding shall be done with grasses consistent with the Rocky Mountain native mix or other grasses reasonably requested by surface owner and during planting period suggested by Owner. Final reclamation shall be completed to the reasonable satisfaction of the Owner as soon as practical after installation (weather permitting) and in accordance with regulatory agency standards (BLM/COGCC).
