7/15/2015 | Storm Water Management Plan (SWMP) will be in place to address construction, drilling and operations associated with oil and gas development through the state of Colorado in accordance with CDPHE General Permit Rules. BMP’s will vary according to location and will remain in place until the pad reaches final reclamation. |

| Drilling/Completion Operations | Form: (02A )
400842176
7/15/2015 | Preferred Option: It is the intent of the County that operators utilize closed-loop or modified closed-loop systems for drilling and completion operations in order to minimize or eliminate the need for earthen pits; however, notwithstanding the foregoing, where appropriate, and subject to prior County approval, the County generally supports: 1) the use of unlined drilling pits when bentonite or a similar clay additive is used during the drilling process, and 2) the use of lined single- or multi-well water storage pits in order to minimize the transport of water and promote recycling, subject to the requirements set forth in this subsection. Permitted modified closedloop systems include oil and gas wells where air or fresh water is used to drill through the surface casing interval, defined as fifty (50) feet below the depth of the deepest aquifer, and a closed loop system is used for the remainder of the drilling and/or completion or recompletion procedures. Multi-well pits are defined as lined, engineered pits, constructed over an engineered base, with construction or liner specifications meeting or exceeding Commission pit lining rules, that will serve the functions of drilling, completion, and/or flowback pits for more than one well. |

7/1/2020 | Secondary Containment
All facilities will be equipped with remote monitoring and remote shut down, which includes isolation at the well head. Engineered liner systems will be used in secondary steel containment systems for tank batteries. Pollution control containers (spill boxes) will be used on truck loading lines and placed within the limits of the secondary containment system. Automatic shutdown level devices will be installed on each tank with remote monitoring capabilities. Automatic shutdown level devices will be installed on all pressure vessels and liquid knockouts. Automatic shutdown pressure devices will be installed on flowlines from well heads to facilities with remote monitoring capabilities. Additionally, cathodic protection will be used on buried steel lines to mitigate corrosion. Automatic shutdown pressure devices will be installed on process vessels with remote monitoring capabilities. |
| Dust control | Form: (02A )
402296399
7/1/2020 | Dust associated with Site activities and traffic on roads will be minimized throughout all phases such that there are no visible dust emissions from sites or roads to the maximum extent practicable given wind conditions. Numerous mitigation measures are in place to minimize dust emissions including (but not limited to): application of fresh water to roads and ground during earth moving activities, curtailment of work during windy conditions and re-establishment of vegetation on disturbed areas that are not graveled. |
| Noise mitigation | Form: (02A )
402296399
7/1/2020 | Operator will use noise mitigation (sound walls) during the drilling and completion phases for the Montezuma 4-64 18-13 4H well site. Based upon modeled receptor locations, the Montezuma 4-64 18-13 4H wellsite is predicted to comply with the A-weighted and C-weighted COGCC noise limits. |

402296399
7/1/2020 | Emissions Controls
Combustors will be available at the Location during the entire production phase to eliminate fugitive emissions in the event of maintenance or emergency use. The device will be fired using natural gas and operate with a 98% or higher hydrocarbon destruction efficiency. The device will be designed and operated in a manner that will ensure no visible emissions during normal operation. Test separators and associated flow lines, sand traps and emission control systems shall be installed on-site to accommodate green completions techniques. When commercial quantities of salable quality gas are achieved at each well, the gas shall be immediately directed to a sales line or shut in and conserved. If a sales line is unavailable or other conditions prevent placing the gas into a sales line, Operator shall not produce the wells without an approved variance per Rule 805.b.(3)C. |
| Odor mitigation | Form: (02A )
402296399
7/1/2020 | Operator will mitigate odors by routing to closed loop systems to the maximum extent practicable. If Operator receives complaints from a Residential Building within 1,320 feet from the site, Operator will take measures to mitigate the odor within 24 hours, based on the specific circumstances. |
| Drilling/Completion Operations | Form: (02A )
