1/13/2021 | KMG holds Surface Impact Planning (SIP) meetings for each planned location. These meetings are attended by KMG internal teams. This is a multi-disciplinary team including construction, operations, facilities, EHS, stakeholder relations, regulatory, surface land and mitigation. The team reviews potential impacts to surrounding residents, identifies and plans for necessary mitigations, and identifies BMPs that should be included in the pad development moving forward. The team reviews noise, odor, lights, traffic, haul routes, rig orientation and visual mitigation and any input we have received from surrounding communities either from response line calls or community meetings, relative to our operations. The purpose of the meeting is to proactively identify potential concerns, exhaust possible options and provide best in class solutions in order to have compatible operations.

1/13/2021 | KMG will create tertiary containment around the well pad and facility by constructing a berm/ditch around the oil & gas location with sediment traps to further protect adjacent water features.
A culvert is proposed at the access road for ditch 0' to the northwest. The natural grade at this proposed location slopes gently from north to south.
Once graded the well pad will be sloped 0.5% to the southwest and northeast from approximately the center of the well pad. The ditch/berm will be engineered to contain and divert runoff around the pad. The ditch/berm will direct flow from north to south through two sediment catch basins. |

402376823
1/13/2021 | Site-Specific Measures: During active construction, drilling, and completions, with personnel on location, daily inspections will occur. During non-active, but while under construction, site inspections will occur every 14 days or after major rain events.
When construction is completed and the location is on production, site inspections will occur every 28 days with additional inspections after major rain events. During construction, stormwater features will be checked more frequently (up to daily, depending on the intensity of construction activity). These construction checks will not be formally documented, since they occur as part of construction oversight, and minor issues will be corrected with no further documentation. If and when larger issues are noted in these construction checks, the associated corrective actions would be documented. |

2) Tanks are inspected and maintained while in use.
3) The only pipes within the containment are related to the temporary tanks (i.e. no external piping is colocated within the containment), and firefighting equipment is likewise not stored within the containment area.
4)Drill cuttings will not remain in storage at the oil and gas location for more than a 24 hours period. Disposal will occur before the end of the 24 hours period. |

| Emissions mitigation | Form: (02A )
402376823
1/13/2021 | Operator will provide air emissions monitoring to detect fugitive emissions at the production facility based upon a plan approved by the Director which will contain, at a minimum, the following conditions. A two-week baseline test will be conducted prior to the start of drilling. The monitors will be placed in proximity of the production facility and will remain in place from the beginning of drilling through production. One month following the initial thirty-day period after drilling commenced, a data summary report will be provided to the COGCC, which will include the first 30 days from the start of drilling, as well as the two-weeks of baseline data. Thereafter, monthly reports will be provided and submitted to the COGCC on a monthly basis for a duration of no less than one year, at which point, Operator may suspend further monitoring, upon approval of the Director and a finding by the Director that such monitoring is no longer necessary to protect public health, safety, welfare, the environment and wildlife resources. The air emissions monitoring will be performed by a third party. |
| Odor mitigation | Form: (02A )
402376823
1/13/2021 | 805.b. Odor Mitigation. Additional BMPs for this location are:
1) Storage of excess drilling fluid (e.g., fluid not being used in the active mud system) in closed, upright tanks.
2) Drill cutting will be run through a centrifugal dryer to minimize odor during temporary time on location and during transport to disposal.
3) Odor neutralizer will be used in the active mud system for management of odors within 24 hours of receipt of a
stakeholder grievance.
4)Drill cuttings will not remain in storage at the oil and gas location for more than a 24 hours period. Disposal will occur before the end of the 24 hour period. |
| Drilling/Completion Operations | Form: (02A )
402376823
1/13/2021 | KMG currently plans to use the water-on-demand system on this location which is a network of over 180 miles of underground pipeline that stretches the length of the 20-mile by 30-mile field to source and transport water to completions crews. This system eliminates more than 2,000 truck trips per day field-wide, while also reducing associated concerns of
traffic, noise, emissions and dust.
