• A recompletion of production well Haffner 41-23 is scheduled in association with the facility maintenance. This mitigation plan is for adding equipment and expanding the disturbance area of an existing location. Construction activities include; adding two VOC burners, replacing the separator, and replacing the production tank. Increased disturbance is west of currently facility, to accommodate the two additional VOC burners. |

12/20/2016 | Planning:
• Lighting on location is considered temporary and will be used during recompletion activities. Permanent lighting will not be installed and utilized during normal production operations. Temporary lighting will be directed downward, inward, and shielded towards location to avoid glare on public roads and Building Units within 1,000 feet. Lighting will be turned off when practical, i.e., no operations being conducted.

12/20/2016 | Traffic Control:
• Recomplete Operations – The recomplete rig will access the well from the north a county road 20. Dust suppression will be used on county road and temporary access road, if needed. Dust suppression could include a combination of water, magnesium chloride, or calcium chloride. Limited traffic speed could also be used for dust mitigation.
• Facility Maintenance Operations - Production of the location will use the existing access road, located directly off of Weld County Road 20. Dust suppression will be used on county road and temporary access road, if needed. Dust suppression could include a combination of water, magnesium chloride, or calcium chloride. Limited traffic speed could also be used for dust mitigation. |

• Noble Energy Inc. designs facilities to avoid releases and to be compliant with all regulations specific to leak detection and control (i.e. SPCC 40CFR112). Daily, monthly and annual inspections are performed at each facility to confirm operational integrity and regulatory compliance. Noble will perform maintenance if it is deemed necessary through any of the scheduled inspections. Automation technology is utilized to monitor any variations in pressures and fluid gauges which could indicate a leak. |

| Noise mitigation | Form: (04 )
401167379
12/20/2016 | Noise Mitigation:
• Recomplete Operations - Well recompletion work is scheduled for the Haffner 41-23 well, and the mitigation plan has been addressed separately. A baseline sound survey will be completed at the residence(s) located 490 feet north east of the Haffner 41-23 well. Engineered sound walls around the recomplete rig will be used, as applicable based on the noise survey findings.
• Facility Maintenance Operations – Sound walls are not planned for the maintenance activities at the facility, based on timing or extend of work completed. |
