2/17/2022 | * Limits of Construction (LOC) will be delineated and marked with lathe and flagging prior to start of construction
* Access Road Construction will follow location delineation and serve as the primary route for construction and operational purposes.
* Vehicle Tracking Controls (VTC) will be installed at the ingress/egress of the location access point and be the primary sediment control measure for equipment and vehicle traffic.
* Diversion Ditch (DD) will be installed around the location perimeter prior to commencement of surface disturbing activities, and act as the primary stormwater control measure.
* Sediment Control Log (SCL) will be used for inlet protection, as check dams to reduce flow velocity, and on disturbed slopes to shorten flow lengths.
* Sediment Basin (SB) will be installed to capture eroded or disturbed soil transport, prior to discharge from the location and the diversion ditch network.
* Culverts are used for diversion ditch crossings, or along access roads. Culverts will be 18" minimum, or appropriately sized to accommodate design flows.
* Inlet Protection (IP), consists of a sediment control measure such as rock sock and sediment control logs, or proprietary inlet insert. Inlet protection will be maintained based on manufacturer recommendations.
* Outlet Protection (OP) includes both sediment control measures or rip rap armoring at culvert outlets. It will be specified based on culvert capacity and corrective action prescriptions during construction operations.
* Seed and Mulch (SM) will be used to stabilize all stockpiles, disturbed areas, and areas no longer in use for production operations, or during interim reclamation. |

2/17/2022 | Erosion Control Measure Deployment:
• Drill seed and mulching application will be completed within 24 hours of seedbed preparation, weather permitting.
• Seed mix will be cross drill seeded throughout the interim reclamation area.
• All seed will be certified weed free and pure live seed (PLS) rated per federal, state, county, and municipal standards.
• Certified weed free grass or wheat origin straw mulch will be uniformly applied at rate of 2,000 lbs./ per acre to cover 100% of the seed bed.
• Mulch will be properly anchored to the soil surface using a commercial straw crimper with a final orientation NE to SW on slopes less than 8% and on contour on greater slopes.
• Hydraulically applied tackifier/Ecomatrix BFM will be applied at a rate of 1,000 lbs./ per acre to sufficiently secure straw mulch through the first growing season on slopes greater than 8%.
• Mulch and tackifier will stabilize soils and increase moisture retention to promote seed germination and establishment and prevent erosion. |

2/17/2022 | During drilling operations, all fluid containing equipment is thoroughly inspected twice a day. Inspections include tanks, piping, and connections to ensure no leaks are present. In the event a leak is detected on equipment, the equipment will be taken out of service and repaired prior to returning to service. All leaks are cleaned up immediately. Inspection findings are logged into a data management system. If routine inspections indicate that the equipment or connections may need to be serviced, the equipment will be taken out of service to ensure all preventive maintenance is taken to minimize leaks or equipment failure. Additional inspections are conducted on a regular basis throughout the day. The following steps are used by drilling operations to detect fluid leaks:
Inspections
a. Documented equipment inspections logged into data management system twice daily.
b. Frequent routine inspections during operations
Routine inspections are not recorded unless a leak is observed.
In the event of the leak being found through the inspections or best management practices, personnel will promptly notify on-call personnel and initiate repair and cleanup of the spill in accordance with Operator’s Waste Management Plan submitted with the Form 2A in accordance with COGCC Rule 304.c.(11) as well as the COGCC 900 Series Rules. |
