10/13/2020 | Caerus is using and modifying existing pads and access roads; directional drilling is planned to minimize habitat loss and fragmentation. |
| Wildlife | Form: (02A )
402340830
10/13/2020 | Onsite biological surveys (wildlife and aquatic) for each new development, using the most recent data sets for wildlife resources, will be conducted prior to any activity.
Caerus uses the Wildlife Resources Matrix (within the approved North Parachute Ranch, Wildlife Mitigation Plan) to identify and document potential impacts or concerns during the project planning phase for proposed drilling/completion operations and construction of roads, pads, and pipelines.
Caerus will perform pre-disturbance surveys when the onsite inspection and commencement of disturbance occur during different field seasons.
Caerus will follow the North Parachute Ranch Integrated Vegetation Management Guidance Document for interim and final reclamation practices, including identifying appropriate seed mixes and invasive weed control measures. |
| Dust control | Form: (02A )
402340830
10/13/2020 | Active measures to prevent fugitive dust emissions from the well pad, well pad access entrance, and other connecting dirt roads during drilling, completion, and production operations will be implemented. Fugitive dust control measures to reduce dust and coating of vegetation and deposition in water sources include the use of water/fluid dust suppression application, the use of speed restrictions, and regular road maintenance. |
| Construction | Form: (02A )
402340830
10/13/2020 | The pad will be constructed as designed and shown on the Construction Layout Drawings. During construction only the minimum amount of vegetation necessary for the construction of roads and facilities will be removed. Topsoil will be
conserved during excavation and will be reused as cover on disturbed areas and perimeter berms. No construction or routine maintenance activities are performed during periods when the soil is too wet to adequately support construction equipment.
Any stockpile(s) for topsoil and excess cut material will be located in work areas surrounded by the BMPs as shown on the Construction Layout Drawings.
Stormwater BMPs will be installed per details in the Stormwater Management Plan (SWMP) and as shown on the Construction Layout Drawings. Disturbed areas of the site will be left in a surface roughened condition. BMPs will be protected, inspected, and repaired as necessary.
All new flowline/pipeline installations will be performed in accordance with new flowline guidance and requirements in the COGCC 1100 Series Rules. All new offsite pipelines will be registered in accordance with the 1100 Series Rules.
Berms or other containment devices shall be constructed to be sufficiently impervious (corrugated steel with synthetic liner) to adequately contain any spilled or released material around crude oil, condensate, and produced water storage tanks, while also ensuring the adequate prevention of significant adverse environmental impacts. |
| Drilling/Completion Operations | Form: (02A )
402340830
10/13/2020 | Closed loop system will be used. No pits will be built. An enclosed flare stack will be used.
Caerus will ensure 110 percent secondary containment for any volume of fluids stored at the location during drilling and completions.
Caerus utilizes a portable containment liner under the substructure of the drilling rig during drilling activities. This protects shallow groundwater from any potential spills surrounding the rig during drilling. A liquid release would simply be vacuumed up from the liner. When drilling activity is completed, the liner is removed and transferred to the next drilling location.
The moisture content of all drill cuttings managed onsite shall be kept as low as practicable to prevent accumulation of liquids greater than de minimis amounts.
All cuttings generated during drilling will be placed in a bermed portion of the well pad prior to onsite beneficial reuse or onsite disposal; the surface where the cuttings will be placed will be constructed to be sufficiently impervious (or temporarily lined) to keep any material from migrating into the subsurface.
Flowback and stimulation fluids will be sent to enclosed tanks, separators, or other containment or filtering equipment before the fluids are placed into the offsite (take away) pipeline; no open top tanks can be used for initial flowback fluids containment; and secondary containment for flowback storage tanks will meet the requirements of Rule 906.d.(1). |
| Interim Reclamation | Form: (02A )
402340830
10/13/2020 | Once all topsoil has been distributed across the site where interim reclamation is planned, the location is then seeded by drill seeding methods or broadcast seeding.
Re-vegetation is accomplished as soon as practical following the preparation of a site for final stabilization. Seeding will be done when seasonal or weather conditions are most favorable. On terrain where drill seeding is appropriate, seed may be planted using a drill equipped with a depth regulator to ensure proper depth of planting.
Re-countouring to help control run-on and run-off will be done in areas where it will not impede ongoing production operations. |
| Final Reclamation | Form: (02A )
402340830
10/13/2020 | The disturbed areas surrounding the well location, including the access road will be recontoured to blend as nearly possible with the natural topography. Final grading of back-filled and cut slopes will be done to prevent erosion and encourage
establishment of vegetation. Previously existing drainages will be re-established.
The long term objective is to establish a self-perpetuating plant community that is compatible with and capable of supporting the identified land use. Noxious weeds will be treated in accordance with applicable COGCC rules and county weed management requirements. |

6/28/2022 | Caerus requests to modify the BMP number 15 listed in the approved Form 2A to state the Caerus will complete pad construction and interim/final reclamation between July 1st-December 15th to avoid greater sage grouse wintering, breeding and nesting periods. This is a 15-day modification to begin civil construction work on July 1st instead of July 15th. The 15-day modification was approved by the BLM on June 24, 2022 and is supported by CPW stipulated in a letter dated June 27, 2022 all of which is attached herein. |

7/19/2022 | Caerus wishes to make a modification to BMP number 5 on document no. 402340830 for the 2A. Caerus will not be utilizing and enclosed flare stack for safety reasons and wishes to make that modification. Next, Caerus will not be utilizing a portable liner under the rig because we utilize a closed loop system which minimizes leaks. Additionally, drilling fluid tanks have pit volume sensors and are monitored through an electric drilling recorder. Lastly, equipment, tanks and lines are regularly monitored as personnel are on-site 24/7 during drilling and completions. |

6/7/2023 | Caerus wishes to modify BMP number 15 for CPW-Wildlife-Avoidance Greater Sage Grouse. Caerus received approval from BLM to commence on-pad maintenance and continuous drilling and completions. Additionally, CPW has provided a letter of support so that Caerus can commence on-pad maintenance and continuous drilling and completions operations ahead of the July 15th timing stipulation period. Caerus intends to conduct on-pad maintenance June 8, 2023 and anticipates that the rig will mobilize on or about June 22nd. See both BLM and CPW concurrence with this plan. |
