Operations at the proposed drill site typically will begin with construction of the site and will include leveling the pad to accommodate the drilling rig. Once the pad construction is completed, drilling rig equipment will be brought onto location and rigged up. Drilling operations, which run twenty-four {24) hours a day until completed, will commence after the rig is "rigged up". The surface holes will be drilled to approximately 2O00 feet using fresh water. Surface casing will then be run and cemented to surface to protect any shallow fresh water zones. Surface casing setting depth is determined from subsurface ground water maps prepared by the State Engineer and supplemented by the latest data available from offsetting wells. The cement is allowed to set, and well control equipment is installed and tested. After about 8 hours of waiting on cement and installing well control equipment, a drill bit is run into the hole to drill the intermediate portion of the well .into the potential oil and gas bearing formations. The wells will be drilled horizontally. The wells will be turned or steered such that a curve will be drilled to approximately 90 degrees or parallel to the surface of the ground. The typical vertical depth for tlhe wells is approximately 7,000-8,000 feet !below ground level. The length of the horizontal leg for three (3) of the wells will be approximately 2.5 miles long. The length of the horizontal leg for one (1) of the wells will be approximately 2:0 miles long. The total Measured Depth (MD) of a typical well in this project is approximately 17,000 — 20,000 feet. Once the horizontal section of the wellbore isdrilled, a string of production casing will be run into the wellbore. This casing will be cemented into place to isolate the productive zones of the reservoir. Bison's drilling rigs are equipped with a closed loop system. The drilling rig will be on location for approximately six (6) days per horizontal well. At the end of the drilling phase, the drilling rig will be moved off location. The completion phase begins when the drilling equipment is transported off the location. Completion operations are conducted twenty-four (24) hours per day over a period of several weeks. The site may be bladed and leveled to accommodate the completion rig and anchors may be set for the complletion rig. Additional operations including cementing, drilling and logging may occur as circumstances require. For horizontal wells, multiple fracture stages are induced along the length of the wellbore in the respective formation into which the well has been drilled. During hydraulic fracturing, water is pumped at high rates and pressures that exceed the minimum in -situ rock stresses and hydraulically fracture the forrnation. Sand is then .pumped into the created fracture to allow gas OB 'SON PERATING Bison IV Operating, LLC 51817th Street, Suite ].800 Denver, CO 80202 Phone: 72(1-6.-6997 Fax: 303-974-1767 and oil to flow freely from the formation into the well bore. The fracturing equipment will consist of one Modular Large Volume Tank (MLVT) for fresh water storage, multiple flowback tanks, pressure pumps, blending and bulk material trucks with other necessary equipment. After fracturing is completed the mobile equipment is removed, excluding tanks that are used to retain the water that is produced during flowback and testing operations. No water is allowed to accumulate or be disposed of on surface. All water is hauled to approved disposal sites or recycled for stimulation use. The flowback tanks will remain on location until the well is rerouted through standard production equipment. The production equipment for these wells will be located adjacent to the wells. Typical equipment will consist of oil and water tanks constructed within berms comprised of steel rings with a synthetic or engineered liner, separators, vapor recovery and emission control equipment, gas compressors, meters, flowlines, and proposed electrical and/or solar equipment. The location will include automation equipment that allows operators to remotely monitor 'pressures, rates, temperatures, valve positions and tank levels. Once production commences, a Bison employee or contractor will monitor the location on a regularly scheduled basis. These inspections are done as a routine part of the lease operator's job. They conduct a visual inspection of the facility which includes all valves, fittings, wellhead, tanks, vapor control systems and all connections. The lease operator reports the tank measurements of the oil, gas sales, and pressure readings. Much of this production information is compiled and submitted to the ECMC on a monthly basis. In addition, the lease operator will inspect the site for hazards and weed control, maintaining the safety and appearance of the Pads. The anticipated lifespan for the proposed well(s) is 3O years. Once .a well is determined to no longer be productive and/or economic, a plugging rig will remove production equipment and plug the productive zone(s) with a combination of bridge plugs and cement plugs. Surface equipment no longer needed will be removed. Final surface restoration will involve removal of any above -ground casing and the installation of regulation markers that will not interfere with subsequent surface use. Remaining disturbance will be restored to the original grade and reseeded in compliance with ECMC and Local Government rules and regulations and in accordance with surface owner's future land use plans. The expected travel routes for this oil and gas development will be directly off of State Highway 14. Traffic will use an existing access road that is approximately 1.O miles east from the intersection of Highway 14 and Weld County Road 102. The existing private access road to the Oil and Gas Location is approximately 1.25 miles. See the attached haul route reap. The duration of construction, drilling, and completion activity is estimated to be between 2-3 months {see Table 1: Proposed Development Schedule below). During this "active operations" phase, vehide traffic will include passenger cars .and pickups, semi-truck/trailers, and tandem truck vehicles. The number of round trips per day expected for each vehicle during active operations is summarized in Table 2.: Estimated Traffic during Active Operations below. The highest traffic volumes are expected during the first two days of and the last two days of both drilling and completions operations. Traffic will intentionally be highest during daylight hours to mitigate noise and dust during non -working hours.

Oil and gas operating companies ("Operators") are required to obtain approval of an Oil and Gas Development Plan ("OGDP") from the Colorado Oil and Gas Conservation Commission ("COGCC") prior to undertaking any new operations such as drilling oil and gas wells or building oil and gas locations. When an Operator submits an OGDP application to the COGCC for consideration, and the application has been received and is deemed complete, COGCC staff begins a formal technical review of the application materials, and a public comment period starts. COGCC has prepared this information sheet to inform the public of the procedural steps involved with the Director's and Commission's review of an OGDP, so that the public is informed and may participate in the review process if they choose. As part of the process, Operators must provide this information sheet to certain recipients, like yourself, that include mineral owners within the area of proposed development and all landowners, homeowners, commercial property owners, tenants, and other entities within 2,000 feet of an oil and gas location proposed by a pending OGDP application. What is an Oil and Gas Development Plan (OGDP)? An OGDP is an Operator's plan to develop oil or gas resources ("minerals") from one or more surface locations. Operators prepare an OGDP and associated application materials, consistent with the requirements of COGCC Rule 303, and submit the plan for approval through the Commission's Hearings process. The application materials include a hearing application; one or more Form 2A, Oil and Gas Location Assessments; a Form 26, Cumulative Impacts Data identification; and a Form 2C, OGDP Certification. The application may also include a request for the establishment of one or more Drilling and Spacing Units ("DSUs"). The OGDP, along with its associated supporting documents, will be heard at a public hearing where the Commission will make a final determination to approve or deny the OGDP application. What are the procedural steps involved with the Director's and Commission's review of Oil and Gas Development Plans? 1. OGDP application is submitted: Operator/ Applicant submits a complete OGDP application with all supporting documents. The written portion of the application is submitted to the COGCC hearings unit via the eFilings system, and Forms 2A, 2B, and 2C are submitted to technical staff via the eForms system. (See Rules 303 a 304) 2. OGDP application is received: The COGCC hearings unit reviews the written hearing application, assigns a docket number for the OGDP, and provides public notice for the hearing. (See Rules 303 £t 504) 3. Completeness determination: The COGCC technical staff and Director review the application materials for completeness. When deemed complete: a. the OGDP application materials are posted on COGCC's website; b. the Operator provides notice (including this information sheet) to relevant persons; c. the public comment period begins; d. the formal consultation period commences as applicable (including relevant/ proximate local governments and other agencies such as Colorado Parks and Wildlife ("CPW") or Colorado Department Page 2 of Public Health and Environment ("CDPHE")); and e. COGCC staff begin their technical review of the OGDP components. (See Rule 303). 4. Director's review of application (technical review): COGCC technical staff conducts the technical review of all application materials to ensure compliance with COGCC Rules, ensure the protection of public health, safety, welfare, the environment, and wildlife resources, and to evaluate potential Cumulative Impacts. The technical review includes analysis and assessment of: a. DSUs and protection of mineral owner's correlative rights; b. proposed surface locations and alternative locations; c. downhole and engineering considerations; d. best management practices; e. public comments and recommendations provided by consulting agencies; financial assurance; and the need for conditions of approval. (See Rule 306) 5. Director's recommendation: Once the Director has reviewed the application materials, the Director provides a written recommendation to the Commission in support of the approval or denial of the OGDP application. The Director will post the recommendation on COGCC's website, notify relevant parties', and submit it to the COGCC hearings unit in preparation for hearing. (See Rule 306.c) 6. Commission's consideration and final action (public hearing): The Commission receives the f. 8. ' Parties who receive this information sheet will not necessarily be included in the notice of the Director's recommendation. Parties who make a public comment on the Form 2A and include their email address will receive the notice of the Director's recommendation. Director's recommendation of the OGDP and begins review of the OGDP with support from the COGCC hearings unit. The review includes all supporting documents, written testimony, public comments, consulting agency recom- mendations, and Director's recommendation. The Commission considers the OGDP at a public hearing, which may include oral testimony provided during the hearing. The Commission makes a final determination and presents its findings in a written order based on the evidence in the record; the Commission's order to approve or deny the OGDP application is final.

The Director may extend or reopen the public comment period per Rule 303.g, for up to an additional 30 days for a proposed OGDP if the Director determines an extension or reopening is reasonable in order to obtain public input. What happens to my comment? Your comment will become part of the public record of the application and will be reviewed by the applicant, COGCC staff, Director, and the Commission. COGCC staff may recommend permit conditions in response to comments. But, Staff does not routinely respond individually to comments; instead, COGCC staff will work directly with the applicant to address the site - specific concerns expressed. Submitted comments may not be immediately visible; it may be a few days before you see your comments posted. This delay allows COGCC supervisory staff to screen for offensive language prior to publication. What if I want to make my comment to the Commission? COGCC Staff and the Director review every comment received on a Form 2A permit application. They review the site specific concerns against the totality of the application materials, including the alternative location analysis, cumulative impacts evaluation, and best management practices proposed by the applicant. When the Director makes a recommendation to the Commission to either approve or deny an OGDP, that recommendation will include the consideration of the public comments received. In their review of an OGDP for a final determination at the administrative hearing, the Commission will have access to the entire record, including your public comment. Can I remain anonymous? Yes. Only the "Comment" portion of your submitted comment will be made publicly viewable. Your name and contact information will be kept confidential, and will only be used by COGCC staff to contact you if necessary in the course of permit application review. If you choose to include your name and contact information in the body of your comment text, it will be part of the public record.

The Colorado Oil and Gas Conservation Commission ("COGCC") prepared this information sheet to provide the public with information related to hydraulic fracturing. Pursuant to Commission Rule 303.e.(2).E, Operators' are required to provide this information sheet to mineral owners within the area of proposed development and all landowners, homeowners, commercial property owners, tenants, and other entities within 2,000 feet of a proposed oil and gas location. What is hydraulic fracturing treatment, and why is it necessary? Hydraulic fracturing treatment is the process of creating small cracks, or "fractures," in the rocks of deep, underground geological formations that have oil and natural gas. The fractures enhance the flow of oil and gas from the formation to the oil and gas well where it flows or is pumped up the well to the production equipment located on the surface of the site. The process of hydraulic fracturing has been used for decades in Colorado, dating back to the 1970s. Operators2 continue to improve hydraulic fracturing, and it is now a standard practice used in almost all oil and gas wells in the state, and across much of the country. Hydraulic fracturing has made it possible to produce oil and gas from rock formations that did not often produce oit and gas in the early to middle part of the twentieth century. What happens before hydraulic fracturing treatment? The operator uses a drilling rig to drill a "surface hole" and set a steel pipe called "surface casing" in the hole. The surface casing may extend many hundreds of feet, sometimes more than 1,000 ' "Operator" as defined in COGCC Rules 2 Hereinafter, and only for the purpose of describing the hydraulic fracture treatment process, the term `operator' includes the operator itself and all contractors and service providers that the operator hires to perform work. feet, underground. The operator places cement on the outside of the surface casing to seal and protect groundwater. The operator tests the surface casing with pressure, then a smatter "production hole" is drilled out the bottom of the surface casing. After completing a formation integrity test, the operator drills down to the geological formation containing oil and gas, usually many thousands of feet underground. The operator towers a production casing into the production hole, and cement is used to make a seal above the deep oil and gas formation. The operator "completes" the well by placing holes, or "perforations" in the casing at the deep oil and gas formation, to allow oit and gas to flow into the well. The welt is then ready for hydraulic fracturing treatment. What happens during and after hydraulic fracturing treatment? The operator performs the treatment by using high pressure water pumps to fracture the deep oil and gas rock formation. The pumps push fracturing fluids down the well and out through the perforations, into the oil and gas rock formation. The hydraulic fracturing fluids are mostly water and sand, with a small amount of chemical additives. The sand, also called "proppant," remains in the fractures to help !keep the fractures open allowing oil and gas to flow through the fractures to the perforations. After hydraulic fracture treatment, the well is allowed to "flowback," meaning hydraulic fracture fluids, oil, gas, and produced water from the formation flow through the perforations and up the well to the surface where the fluids are separated. The operator sells the oil and gas. Waste products, mostly water produced from the oil and gas formation and hydraulic fracture fluids, are captured and stored for proper treatment or disposal. Page 2 Overhead view of a multiple -well site with hydraulic fracturing equipment set up inside a sound wall Common questions and answers about hydraulic fracturing treatment. Q: How is an oil and gas well designed to be protective of public health, the environment, and wildlife resources? A: COGCC engineering staff review all well permits to ensure that wells are lined with multiple layers of steel and cement sufficient to isolate groundwater from the deep oil and gas rock formations. The operator's wellbore design must meet COGCC wellbore isolation standards and rules in order to receive a permit to drill. Surface casing extends from the ground surface to 50 feet or more below groundwater. Production casing is cemented to seal the oil and gas formation in the well and prevent flow between groundwater and the oil and gas formations. The operator performs a well survey, called a "cement bond log," to verify the cement placement around the production casing. Additionally, the operator pressure tests surface equipment and ensures that nearby, "offset" wells that are close enough for pressure communication in the oil and gas formation have properly -rated surface equipment or downhole plugs. Q: Will hydraulic fracturing treatment cause problems with water wells A: Water well problems related to hydraulic fracturing in Colorado are rare, which is largely a result of COGCC's long-standing mission to protect Waters of the State of Colorado, including groundwater. Most recently, the COGCC adopted new rules for wellbore isolation, effective November 2, 2020 to further strengthen this mandate. Geologic factors in Colorado also serve to help prevent groundwater impacts. Often, many thousands of feet of confining rock layers separate shallow groundwater formations that are used for drinking water, livestock, and irrigation from deep oil and gas formations. In cases where an operator intends to perform a hydraulic fracture treatment at a depth of less than 2,000 feet underground, a geological and engineering evaluation is required prior to approving a drilling permit. In cases where deep groundwater is present, COGCC rules require additional cement in oil and gas wells to seal the deep groundwater formations. Q: What is hydraulic fracture fluid? A: The COGCC and regulatory agencies of other oil and gas producing states partner with FracFocus, a Chemical Disclosure Registry, that operators use to report hydraulic fracture fluid chemical data (https: //www.fracfocus.ortz2/ ). According to FracFocus, approximately 98% to 99% of the fracturing fluid volume in most wells is water and sand. The remaining portion is made up of chemical additives used to reduce friction during pumping and prevent corrosion of the steel casing. Biocide is used to kill bacteria in the water. Surfactants promote water flowback from the formation, up the well and into the oil and gas production equipment at the well site or a nearby "tank battery." Fracturing chemicals are similar to other industrial chemicals which must be handled properly. COGCC rules require that operators properly store and handle chemicals in a manner that protects operator's employees, the public, the environment, and wildlife, COGCC rules require operators to publicly disclose the components and concentrations of fracturing chemicals for each well within 60 days of the hydraulic fracture treatment on the FracFocus website, which is searchable by county, operator, and well. The website also provides information on chemicals used and their purpose. Version 2.1 April 2, 2021 Page 3 Q: How are hydraulic fracturing fluids managed on the well site? A: Operators manage Large volumes of drilling fluid, hydraulic fracturing fluid, and flowback during drilling and hydraulic fracturing treatment. Operators protect the public, environmental resources, and wildlife by implementing best management practices specified by permit conditions and COGCC rules for spill prevention. After hydraulic fracturing treatment, fluids return to production equipment at the welt site as fiowback. These flowback fluids are considered oil and gas Exploration and Production Waste ("EEtP Waste") that are recycled for other oil and gas operations, or are disposed of in accordance with state regulations. Marketable production fluids, including oil and gas, are separated and contained in tanks or vessels, or sent by pipeline to sales. Q: What can neighbors expect to experience during hydraulic fracturing treatment? A: The operator provides the COGCC and the local, government a 48 -hour notice before performing hydraulic fracturing treatment. As the operator mobilizes the hydraulic fracturing crews, water tanks are placed at the site. The operator transports water to the site for hydraulic fracturing fluid by pipeline or water trucks. Heavy equipment, such as sand haulers, pump trucks, blending units and a control van arrives and the equipment is connected to the well with high pressure piping. The operator pressure tests the equipment, then the hydraulic fracture treatment begins. The work can take several days to several weeks, depending on the number of wells on the well site and the number of treatment stages needed for each well. The equipment noise from engines, pumps, and vehicles will be noticeable during the work. Induced seismicity from hydraulic fracturing is very low intensity, too small to be noticed by people at the ground surface, and therefore man-made earthquakes are not a common occurrence in Colorado during hydraulic fracturing treatment operations. Where can I get additional information? FracFocus (www.fracfocus.org) contains detailed information on hydraulic fracturing, chemicals used, groundwater protection and how to find a well near you. COGCC rules related to hydraulic fracturing: • Rule 308 Form 2, Application to Drill, Deepen, Re -Enter, or Recomplete, and Operate, Information Requirements Rule 405.k Notice of Intent to Conduct Hydraulic Fracturing Treatment • Rule 408 General Drilling Rules • Rule 411 Public Water System Protection • Rule 419 Bradenhead Monitoring, Testing, and Reporting • Rule 423 and 424 Noise and Lighting • Rule 437 Hydraulic Fracturing Chemical Additives • Rule 614 Coalbed Methane Wells • Rule 615 Groundwater Baseline Sampling and Monitoring Rule 905 Management of EftP Waste Rule 912 Spills and Releases (includes landowner notification requirements) COGCC's rules are available as downloadable files at coKc.state.co.us. Version 2.1 April 2, 2021 D COLORADO o l & Gas Conservation Commission Department of Naftali' Resources COGCC INFORMATION SHEET: OGDP STATUS INFORMATION (As required by COGCC Rule 303.a(2).G) Why am I receiving this information sheet? The Colorado Oil and Gas Conservation Commission ("COGCC") prepared this information sheet to inform the public in the vicinity of a proposed Oil and Gas Development Plan ("OGDP") how to access documents and view the status of proposed OGDPs through the COGCC's website, eForms, and eFiling system. A review of public property records indicates that you may have an interest in lands that an oil and gas operator wishes to develop as part of an OGDP. Pursuant to Commission Rule 303.e. (2).G, operators are required to provide this information sheet to certain recipients near their development plans. What is an oil and Gas Development Plan? An OGDP is an operator's plan to develop subsurface oil and gas resources ("minerals") from one or more surface locations. An OGDP consists of a hearing application and associated permit materials that provide technical information. The Director (i.e. COGCC Staff) reviews the technical information and makes a recommendation to the Commission for the hearings application; the Commission has the ultimate authority on approvat or denial of the OGDP. How do I view the status of the pending OGDP hearing application? Members of the public may view the status of proposed OGDP applications through the COGCC eFiling System by creating an account in the Applications and Docket Portal, available on the "Hearings Page." 1.
