2/28/2018 | Visual Impacts: All long term facility structures will be painted a color that enables the facilities to blend in with the natural background color of the landscape, as seen from a viewing distance and location typically used by the public.
Maintain appearance with garbage clean-up; a trash bin will be located on site to accumulate waste by the personnel drilling the wells. Site will have unused equipment, trash and junk removed immediately. |
| Storm Water/Erosion Control | Form: (02A )
401189323
2/28/2018 | 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). |
| Dust control | Form: (02A )
401189323
2/28/2018 | Operator shall employ practices for control of fugitive dust caused by their operations. Such practices shall include but are not limited to the use of speed restrictions, regular road maintenance, restriction of construction activity during high- wind days, and silica dust controls when handling sand used in hydraulic fracturing operations. Additional management practices such as road surfacing, wind breaks and barriers may be used. |
| Construction | Form: (02A )
401189323
2/28/2018 | Permanent lighting will be installed around the facility to allow both the operator and haulers to conduct safe operations at night. All lights will be directed down toward the location or shielded so no light pollution leaves the facility. |
| Odor mitigation | Form: (02A )
401189323
2/28/2018 | Oil & gas facilities and equipment shall be operated in such a manner that odors and dust do not constitute a nuisance or hazard to public welfare. Operator is in the process of implementing a new base fluid for Oil Base Mud systems. The aromatics and BTEX concentrations are much less than that of generic diesel. With these two things being the major contributors to the odor from diesel, this should lead to less odor at the drill site caused by OBM. |
| Drilling/Completion Operations | Form: (02A )
401189323
2/28/2018 | Operator has an MLVT Design Package, certified and sealed by a licensed professional engineer, which is on file in their office and available upon request. The site shall be prepared in accordance with the specifications of the design package prior to tank installation; including ensuring that proper compaction requirements have been met.
The MLVT will be at least 75 feet from a wellhead, fired vessel, heater-treater, or a compressor with a rating of 200 horsepower or more. It will be placed at least 50 feet from a separator, well test unit, or other non-fired equipment.
All liner seams will be welded and tested in accordance with applicable ASTM International standards.
Operator will be present during initial filling of the MLVT and the contractor will supervise and inspect the MLVT for leaks during filling.
Operator will comply with the testing and re-inspection requirements and associated written standard operating procedures (SOP) listed on the design package.
Signs will be posted on the MLVT indicating that the contents are freshwater.
The MLVT will be operated with a minimum of 1 foot of freeboard at all times.
Access to the MLVT will be limited to operational personnel and authorized regulatory agency personnel.
Operator or contractor will conduct daily visual inspections of the exterior wall and surrounding area for integrity deficiencies.
Operator has developed a contingency plan/emergency response plan associated with the MLVT and it is on file at their office.
A fabric reinforced liner will be utilized. In the event that a tank breach were to occur, the fabric reinforced liner will prevent a “zippering” failure from occurring. The liner will meet the specifications per the design package.
Operator acknowledges and will comply with the Colorado Oil & Gas Conservation Commission Policy on the Use of Modular Large Volume Tanks in Colorado dated June 13, 2014.

| Interim Reclamation | Form: (02A )
401189323
2/28/2018 | Operator shall be responsible for segregating the topsoil, backfilling, re-compacting, reseeding, and re-contouring the surface of any disturbed area so as not to interfere with Owner’s operations and shall reclaim such area to be returned to pre-existing conditions as best as possible with control of all noxious weeds. |
| Drilling/Completion Operations | Form: (04 )

6/3/2022 | Operator will position lighting during drilling and completions operations on the sound walls in a downward manner to avoid and minimize light leaving location. |
| Community Outreach and Notification | Form: (04 )
402963274
6/3/2022 | Operator will send out Move In Rig Up Notices (MIRU) notices compliant with COGCC Rule 412.b. These notices will contain the COGCC Complaints Fact Sheet and a link to a project-specific-website that is being developed to provide more information regarding the development process. |
| Noise mitigation | Form: (04 )
402963274
6/3/2022 | Operator shall comply with COGCC Rule 423. Construction activity will take place during daylight hours only. Thirty-two (32) foot tall soundwalls will be installed on all sides of the well pad during drilling and completion operations; openings will be required on the west side of the pad for ingress/egress. |
| Odor mitigation | Form: (04 )
402963274
6/3/2022 | Operator shall employ IOGP Group II drilling fluids, with low to negligible aromatic contact, during drilling operations after surface casing is set and freshwater aquifers are protected. |
| Dust control | Form: (04 )
403330156
3/22/2023 | Dust suppression during construction will be accomplished by the application of freshwater to the access road(s) and exposed earthen surfaces to reduce the transportability of dust when atmospheric conditions are conducive to sustained winds and/or periodic gusts. All dust suppression efforts will consist of only freshwater unless otherwise requested and approved as applicable.
To minimize sand-related dust emissions, the Operator will be utilizing containerized box technology for sand transport, storage and use during the completions phase. These sand containers (or “sand boxes”) are sealed containers that protect the sand from exposure to wind and prevent dust generation.
Operator will perform regular inspections and road maintenance to ensure the integrity of the access road and associated features is maintained throughout the life of this project. Maintenance consists of re-compacting the road base/recycled asphalt mix on an as-needed basis.
Operator will install and maintain vehicle tracking controls (i.e., coarse aggregate, a tracking pad, paved apron, or cattle guard) to further reduce and remove loose mud and dirt on construction equipment and vehicles servicing location. |

3/22/2023 | Operator will utilize a quiet completions fleet for the proposed completion operations.
Five (5) continuous noise monitoring terminals depicted on the attached exhibit will be placed proximal to residential building units to monitor sound levels and ensure compliance. |
