10/27/2020 | Access Roads: KMG will utilize one existing access road off of CR 17 for temporary operations, up until the temporary tanks are removed. After the temporary tanks are removed, KMG will then use the proposed existing permanent access. KMG chose to use the temporary access in order to be further away from the surrounding building unit owners.
Both roads will be properly constructed and maintained to accommodate for local emergency vehicle access. |

10/27/2020 | KMG held Surface Impact Planning (SIP) meetings for the Schlagel pad 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 the surrounding residents, identify and plan for necessary mitigations, and identify 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. |

10/27/2020 | KMG currently plans to use the water-on-demand system on this location which is a network of over 180 miles of underground pipelines 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, also reducing associated concerns of traffic, noise, emissions and dust. |

10/27/2020 | KMG and its contractors will employ best management practices during the drilling and production of its wells and will comply with appropriate COGCC rules concerning fire prevention. Flammable liquids will not be stored within (fifty) 50’ of the proposed wellheads. If storage of flammable liquid is to be conducted within (fifty) 50’ of the wellhead, sufficient safety measures will be implemented. |
| Storm Water/Erosion Control | Form: (02A )

10/27/2020 | Kerr-McGee will create tertiary containment around the facility by constructing a berm or diversion dike, site grading, sediment traps or other comparable measures sufficient to further protect adjacent water features, including the ditches and ponds near this proposed oil and gas location. During active construction, 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. |

10/27/2020 | KMG maintains a Stormwater Management Plan that assesses erosion control for every KMG operated location. This location will be added to this plan once construction begins. This site will be inspected every fourteen (14) days during construction activities, every twenty-eight (28) days after construction is completed, and after any major weather event. |

10/27/2020 | Berm Construction: A geosynthetic liner will be laid under the long-term tanks on this location and a metal containment will be constructed. Secondary containment devices will be constructed around crude oil, condensate, and produced water storage tanks and shall enclose an area sufficient to contain and provide secondary containment for 150% of the largest single tank. Secondary containment devices shall be inspected at the same time as stormwater inspections, with personnel on location, daily inspections will occur. During non-active, but while under construction, site inspections will occur every 14 days. When construction is completed and the Location is on production, site inspections will occur every 28 days. |
| Material Handling and Spill Prevention | Form: (02A )

10/27/2020 | Temporary produced water storage tanks shall be designed, constructed, and maintained in accordance with the following portions of the National Fire Protection Association (NFPA) Code 30 (2008 version):
1) Tanks are built to engineering standards using noncombustible materials, with relief devise sizing based on API 2000
standards.
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. |

10/27/2020 | Berm Construction: The temporary produced water storage tanks will be staged on a geosynthetic liner and surrounded by an earthen berm. The berms shall enclose an area sufficient to provide secondary containment for 150% of the volume of the largest single tank and shall be sufficiently impervious to contain spilled or released material. Berms and the liner shall be inspected at the same time as stormwater inspections, with personnel on location, daily inspections will occur. During non-active, but while under construction, site inspections will occur every 14 days. When construction is completed and the location is on production, site inspections will occur every 28 days. |

1) The 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 hour period. Disposal will occur before the end of the 24 hour period. |
