| General Housekeeping | Form: (02A )
402735734
4/8/2022 | Waste Management- General housekeeping will consist of neat and orderly storage of materials and fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at offsite, permitted facilities. If spills occur, cleanup will be implemented within 24-48 hours, as appropriate, to minimize any commingling of waste materials with storm water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Any waste product from maintenance will be containerized and transported offsite for disposal or recycling. There will be no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup will consist of patrolling the roadways, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, and any contaminated soil. |
| Storm Water/Erosion Control | Form: (02A )
402735734
4/8/2022 | Storm Water Control - Storm water controls will be constructed around the perimeter of the site prior to construction. Typically, Operator utilizes a ditch and berm system of storm water controls on location. BMP's used are determined just prior to construction by a third party storm water contractor and may vary according to the location. Storm water controls will remain in place until the pad reaches final reclamation. |
| Material Handling and Spill Prevention | Form: (02A )
402735734

Operator shall use SCADA information systems that have the ability to remotely monitor well production and shut in wells to stop a fluid release during upset conditions. |
| Material Handling and Spill Prevention | Form: (02A )
402735734
4/8/2022 | Pigging Activity- Operator shall conduct closed loop pigging to the oil pipeline, gas lift pipeline, and gas gathering pipeline for this operation. This practice removes paraffin's and deposits deposits in the pipeline without open-ended liquid collection. The deposits are flushed through the active pipelines to the production equipment. This practice reduces the potential for releases and emissions related to open loop methods. Operator shall use a small containment under the receiver when removing the pig to reduce the potential for spills. |
| Material Handling and Spill Prevention | Form: (02A )
402735734
4/8/2022 | Removal of Onsite Produced Fluid Storage - To protect shallow groundwater and nearby surface water, Operator shall transfer, via flowlines, produced fluids to an offsite location for storage or final transportation to sales/disposal. This does not include the maintenance tank which is for well maintenance and only stores produced fluid temporarily for final disposal. |
| Material Handling and Spill Prevention | Form: (02A )
402735734
4/8/2022 | Maintenance Tank Containment - Operator shall construct maintenance tanks inside lined containment. The containment will be constructed to hold the entire contents of the maintenance tank in the event of a potential fluid release plus sufficient freeboard for precipitation. The precipitation amount for the 25-year, 24-hour storm in Weld County, Colorado is assumed to be 3.4 inches |
| Material Handling and Spill Prevention | Form: (02A )

4/8/2022 | During Drilling Operations, For containment, Bonanza uses a liner under all drilling equipment holding OBM, distillate or diesel so a
leak won’t touch the ground and is easier to identify. |
| Material Handling and Spill Prevention | Form: (02A )
402735734
4/8/2022 | -During completion operations, Bonanza keeps an accurate account of volume levels on all tanks, and transports. Automation and alarms are used for fuel.
-When completing transfers between the transports there is always two people on the transfer, one on each end with radio’s so they can communicate and don’t over fill or leave a pump running; all transfers are done on containment.
-For containment, Bonanza uses an approved and inspected liner under all completions equipment holding any type of fluid/chemicals or diesel so a leak won’t touch the ground and is easier to identify.
-Any time there needs to be a connection, fluid is pumped to frac tanks. Then they are pressure tested to ensure there are no leaks when reconnected.
-Crews/consultants perform multiple inspections per day around the equipment the pad to ensure there are no spills or minor leaks on any equipment, hoses or connections. |
| Dust control | Form: (02A )
402735734
4/8/2022 | BCEOC will employ practices for continuous control of fugitive dust caused by operations. These practices shall include but are not limited to:
- The use of speed restrictions.
- Regular road maintenance.
- Restriction of construction activity during high-wind days.
- BCEOC will provide dust control, during new location construction, around tanks and wellheads, and on lease roads if excess dust is present with a temporary suppressant such as water.
- BCEOC uses a gravity fed box proppant delivery system that meets OSHA standards, rather than the historic pneumatic trailer proppant transfer system that blows sand out of the trailer into frac sand silos on the location; a method that required supplemental dust control to meet OSHA requirements. With a gravity fed proppant delivery system, the delivery container is also a well pad storage container, eliminating the need for frac sand silos on location. Storing frac sand in containers reduces sand dust during fracing operations by dropping sand directly from the container into the blender sand hopper.
- Automation is used on all new wells to minimize truck traffic. |
| Construction | Form: (02A )
402735734
4/8/2022 | Construction - Operator shall construct this location with a compacted road base surface. This surface is at least 4 inches thick and compacted to prevent surface degradation from drilling and production activity and traffic. This layer of road base protects shallow groundwater by containing liquids and preventing vertical migration of a potential spill. The private road network providing ingress and egress to the access road consists of dirt roads for several miles before reaching improved public roadways (i.e., asphalt, concrete, gravel). The private road network includes multiple cattle guards which also serve to reduce mud tracking. No additional mud tracking is proposed. |
| Emissions mitigation | Form: (02A )
402735734
4/8/2022 | - BCEOC will not flare produced gas during normal operations.
- BCEOC will use supervisory control and data acquisition (SCADA) systems to monitor well operations, which will reduce emissions from vehicle traffic due to the reduced number of vehicle trips to the site.
- BCEOC has an 24/7 Field Monitoring (FMR) that allows for continuous monitoring operating conditions when personnel are not on-site in order to identify and correct any improper operations as soon as possible.
- BCEOC has a Preventative Maintenance (PM) program that contributes to the decrease in fugitive emissions and spills related to non-functioning or aging equipment.
- BCEOC will implement a Leak Detection and Repair program (LDAR) including monthly inspections using infrared (e.g., FLIR) cameras.
- As BCEOC is committed to closed-loop drilling there will be no emission-producing reserve pits.
