Maintain appearance with garbage clean-up; a trash bin will be located on site to accumulate waste by the personnel drilling the wells. Site will have unused equipment, trash and junk removed immediately. Operator shall keep the Surface Use Area as well as any roads or other areas used by Operator safe and in good order, including control of noxious weeds litter and debris. false c4691ef6-d3c6-40ea-8391-261a396a329c 402179770 7 Construction Guy line anchors: All guy line anchors shall be brightly marked pursuant to Rule 604.c.(2)Q. Berm Construction: Tank berms shall be constructed of steel rings with a synthetic or engineered liner and designed to contain 150% of the capacity of the largest tank. All berms will be visually checked periodically to ensure proper working condition. Containment berms shall be constructed and designed to prevent leakage and resist degradation from erosion or routine operation. Tertiary containment, such as an earthen berm, will be installed as required for Production Facilities within 500 feet of a down gradient surface water feature. All berms will be visually checked periodically to ensure proper working condition. Lighting: Site lighting shall be directed downward and inward and shielded so as to avoid glare on public roads and Building Units within one thousand (1000) feet. Once the drilling and completion rigs leave the site, there will be lighting on site to ensure safe oil and gas operations. Such lighting will be controlled manually or by timers and will not be on constantly during nighttime hours. false cbf322d5-b704-4eb6-b1d0-3a8b618066f4 402179770 14 Drilling/Completion Operations A closed–loop system will be used for drilling operations. false 195dcbb8-509a-48ae-ad23-3df2bdf39d4b 402179770 11 Noise mitigation Operator will provide 32’ engineered noise abatement sound walls to comply with COGCC requirements and Surface Use Agreement stipulations. Sound walls will be installed minimally along the North, West, and South sides of the site for the duration of drilling and completion activities. A third party predrill sound model study will be developed utilizing the drilling rig and completion frac fleet noise signatures, and if such modelling indicates a need for sounds walls along the East side of the site, they will also be provided by Bayswater. Baseline studies will be conducted prior to commencement of construction and dirt work, which includes both A and C scale measurements. A sound model will be developed with the drilling rig and completion operations noise signatures. Operator utilizes appropriately sized sounds walls for installation around production facility compressor units to dampen noise. These walls are based on a forecasted model with the production facilities’ noise signature. false e6c4b674-f507-4740-b33f-4d726155d78e 402179770 16 Final Reclamation Within 90 days subsequent to the time of plugging and abandonment of the entire site, superfluous debris and equipment shall be removed from the site. The Operator shall restore the surface of the land affected by such terminated operations as near as possible to the previous state that existed prior to operations. false fd62981b-4a97-4a32-8202-4ed157475eaa 402179770 8 Construction 604.c.(2).K. No pits will be used on location, therefore pit level Indicators will not be used on location. false a9880c65-d578-4448-9f09-5233c5caf3ef 402179770 2 Traffic control Access Roads: The access road will be constructed to accommodate local emergency vehicles. This road will be maintained for access at all times. Weld County doesn't require a traffic control plan or a traffic study for drilling operations. An access permit will be obtained from Weld County prior to construction. false e894bd4c-c25b-43df-b13b-56dc5acbfdfc 402179770 13 Odor mitigation Oil & gas facilities and equipment shall be operated in such a manner that odors and dust do not constitute a nuisance or hazard to public welfare. Operator utilizes a clear, colorless refined distillate derived from petro hydrocarbons that is specifically designed for down hole OBM drilling purposes. This product provides a higher aniline point and a lower BTEX than straight diesel which should reduce the odor associated with the OBM system. The refined distillate is a non-Group II or Group III fluid and is not an additive/odor neutralizer. An additive/odor neutralizer location during drilling and completion and the utilization of closed flowback tanks with all water vapors being sent to a temporary ECD during the flowback period will also be used to help mitigate aromatics on location. Oil and gas operations shall be in compliance with the Department of Public Health and Environment, Air Quality Control Commission, Regulation No. 2 Odor Emission, 5 C.C.R. 1001-4, Regulation No. 3 (5 C.C.R. 1001-5), and Regulation No. 7 Section XVII.B.1 (a-c) and Section XII. false e982425d-8fed-47a6-aad1-6545b8dc74dc 402179770 1 Planning Multi-well Pads are selected in a manner that allows for resource extraction while maintaining the greatest measurement from offsetting residential areas, while also honoring the wishes of the surface owner. Bayswater utilizes flood plain information, COGCC setbacks, development strategies, economics, mechanical and well bore integrity, safety, traffic, geology and operations life cycles among other items when planning horizontal sites. Bayswater plans extended reach laterals to minimize the number of disturbance areas and the number of multi-well sites. The use of existing pad sites, access roads and the proximity to pipelines all play important roles in site selection. Additionally, Bayswater looks at the torque and drag on drilling operations to see what the limitations are on site selection compared to landing points of the laterals. Bayswater will continue to be in close communication with Surface Owner(s) with respect to land use consideration, construction and drilling rig move-in date. A meeting with the surface owner will determine the fencing and sound wall plan. Tanks will be designed, constructed and maintained in accordance with NFPA Code 30. The tanks are visually inspected by the lease operators and weekly AVO inspections are performed and documented. false e0b70f63-5ac4-428a-9ddc-68cd5d2e64e8 402179770 6 Dust control Operator shall employ practices for control of fugitive dust caused by their operations. Such practices shall include but are not limited to the use of speed restrictions, regular road maintenance, restriction of construction activity during high-wind days, and silica dust controls when handling sand used in hydraulic fracturing operations. Bayswater additionally has implemented the use of traffic signs when leaving the location to remind drivers of specific routes to utilize. false 53780173-e9b2-430a-8bce-9990715a271d 402179770 9 Construction 604.c.(2)M. Fencing: A meeting with the surface owner will occur after completions but before interim reclamation to determine a fencing plan. The location will be adequately secured to restrict access by unauthorized persons in accordance with the surface owner’s requests. false 3a5f7e75-99e5-4d99-b120-a3f43166fc33 402179770 15 Interim Reclamation Operator shall be responsible for segregating the topsoil, backfilling, repacking, reseeding, and recontouring the surface of any disturbed area so as not to interfere with Owner’s operations and shall reclaim such area to be returned to pre-existing conditions as best as possible with control of all weeds. false 48f6b73d-f895-4381-8b94-dc083454f9f1 402179770 5 Material Handling and Spill Prevention Leak Detention Plan: Pumper will visit the location daily and visually inspect all wellheads and fittings for leaks. Additionally, annual documented SPCCP inspections are conducted pursuant to 40 CFR 112. Control of fire hazards: All material that is considered a fire hazard shall be a minimum of 25 feet from the wellhead. Electrical equipment shall comply with API RP 500 and will comply with the current national electrical code. Flammable liquids shall not be stored within fifty (50) feet of the wellbore, except for the fuel in the tanks of operating equipment or supply for injection pumps. Where terrain and location configuration do not permit maintaining this distance, equivalent safety measures should be taken. Electrical equipment shall comply with API RP 500 and will comply with the current national electrical code. Automation: The location will be completely automated to monitor all production operations remotely. In the event that the facility is not operating under normal conditions, the automation system will immediately notify the operator. The automation system also has the ability to remotely perform an emergency shut down if necessary. Operator shall comply with state and federal laws, rules and regulations governing the presence of any petroleum products, toxic or hazardous chemicals or wastes on the Subject lands. false c78e58f3-09e7-41df-9f69-e559c2789534 402179770 4 Storm Water/Erosion Control Operator shall install stormwater controls, constructed in a manner that is consistent with good engineering practices, that will prevent offsite migration of sediment/contaminant, into the nearby sensitive areas. Stormwater controls shall be installed prior to construction activities. Gas, oil, and water gathering lines will be co-located to minimize potential of erosion associated with construction of any pipeline(s). false ba207a3a-17cf-461b-bd0b-fabe68656e33 402179770 12 Emissions mitigation Green Completions - Test separators and associated flow lines, sand traps and emission control systems shall be installed on-site to accommodate green completions techniques. When commercial quantities of salable quality gas are achieved at each well, the gas shall be immediately directed to a sales line or shut in and conserved. If a sales line is unavailable or other conditions prevent placing the gas into a sales line, the operator shall not produce the wells without an approved variance per Rule 805.b.(3)C. false 88112552-6935-48b5-86c2-fed8b295e19e 402179770 10 Construction 604.c.(2).O. All oil and water loadouts that are commonly used have a load bucket and isolation valve. Since they are used often, there is not a bull plug installed. Any loadouts (water on back of tanks for example) that are rarely used, are bull plugged without a load bucket. false 402179770 Vic Leffler & Sons Inc
