6/6/2022 | Operator will conduct all vegetation removal necessary for Oil and Gas Operations outside of the nesting season for migratory birds (April 1 to August 31). For any vegetation removal that must be scheduled between April 1 to August 31, Operator may implement appropriate hazing or other exclusion measures prior to April 1. If hazing or other exclusion measures are not implemented, Operator will assign a qualified contractor to conduct pre-construction nesting migratory bird surveys within the approved disturbance area prior to any vegetation removal during the nesting season. If active nest(s) are located, Operator will provide work zone buffers around active nests. |

6/6/2022 | The following BMPs will be implemented on Bigfoot 11:
• A Stormwater Detention Pond will remain at the entrance to the well pad.
• Filter Logs will be installed on the entire western side, western half of the northern side, and along the entire southwest side of the well pad.
• Diversion Channels with rocked check dams will be installed around the well pad directing water to the stormwater detention pond and/or away from the well pad. Additional diversion channels will be placed above the cut slope along the eastern-half of the northern side and the southern half of the eastern side.
• Rock Rip-Rap will be placed on both sides of the access road to the pad will slow/filter any stormwater runoff from the road itself. Rock rip-rap apron will also be installed on the eastern edge of the topsoil pile.
• The location will be recontoured, topsoil reapplied, and the reduced area stabilized with seed, hydroseed, bonded fiber matrix, mulch, etc. as deemed appropriate for the site.
• The borrow ditches will be reseeded to promote topsoil stabilization and will reduce the area utilized by this location.
• If the reclaimed area is not put back into crop land, the seed mix planned to be utilized for the Bigfoot 11 location is Buffalo Brand Sandy Soil Mix.
• Topsoil will be segregated from cut areas for use in reclamation.
• Salvaging and spreading of topsoil will not be performed when the ground or topsoil is frozen or too wet to adequately support construction equipment. If such equipment creates ruts more than four inches deep, the soil will be deemed too wet |

6/6/2022 | Operator will perform daily AVO inspection methods during all phases of activity. Operator will employ trained personnel and document all inspection findings, if any. Above ground flowlines will be visually inspected on a weekly basis and tested triennially for leaks. Underground lines will be pressure tested every 3 years. Pressure testing records will be maintained by operator for a minimum of 10 years. |

6/6/2022 | PVT alarms, automation and other sensory monitoring devices will be utilized to monitor active tank levels at all times. During any transfer operations, visual inspections from inlet and outlet vessels with radio communication will be implemented. Daily visual inspections will be performed on all equipment, hoses and valving to ensure integrity of fluid containment at all times. |

6/6/2022 | A secondary means of containment is provided for all tank batteries, separation units, and treating equipment. Secondary containment structures for aboveground storage tanks are sized such that each will be able to contain the volume of the largest storage container and enough freeboard to contain precipitation from a 25-year 24-hour storm event. |

6/6/2022 | Remote technologies (for example, supervisory control and data acquisition (SCADA) will be used to monitor well operations. This will reduce emissions from vehicle traffic by reducing the number of vehicle trips to the site. Proposed wells will be equipped with technology that will allow for automatic well shutin in the event of an unplanned release. |

6/6/2022 | During completions, if an upset condition occurs, the gas will be routed to an enclosed combustion device (ECD) until normal operations can resume. Should Upset Conditions occur for longer than 24 cumulative hours, Operator will seek Director’s verbal approval to continue to combust beyond 24 cumulative hours and will subsequently file a Form 04 Sundry within seven (7) days to report the Upset Condition and the safety concern associated therewith.
During flowback, until quantities of gas that are sufficient to purge facility equipment, gas will be combusted in an ECD. A gas sales line will be constructed prior to flowback. When able, all gas will flow directly into the pipeline. If an upset condition were to occur after starting sales, the gas will be routed to an ECD until normal operations can resume. Should Upset Conditions occur for longer than 24 cumulative hours, Operator will seek Director’s verbal approval to continue to flare beyond 24 cumulative hours and will subsequently file a Form 04 Sundry within seven (7) days to report the Upset Condition and the safety concern associated therewith. |
