ACCESS AND ROADWAYS The proposed booster compressor facility will not require construction of new roads. The use will utilize the existing access from Daybreak Drive off of CR 300 (Stone Quarry Road). Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 3 A. Access to Public Right of Way No new roads are proposed to accommodate the proposed booster compressor facility. Access to the subject property is from County Road 300, Daybreak Drive and via a private driveway. The existing roadway and access are adequate for the anticipated low traffic volumes (see Road Assessment Report and Letter by Matrix Design Group). Dust from the private driveway will be mitigated as appropriate. B. Safe Access The access driveway meets most of the Primitive Roadway/Driveway standards of Table 7-107 of the Land Use and Development Code. Design Standards waivers have been requested for ROW width and ditch widths. The county road system and private driveway provides safe access to the facility. See the Road Assessment report for further information. An access permit for Daybreak Road is included. C. Adequate Capacity The proposed facility will not generate additional traffic after installation. The current road system has adequate capacity to support the proposed booster compressor. The Traffic Study included with this application gives details for the traffic volumes based on the previously approved injection well. The report has been updated by a Technical Memorandum from Olsson Associate’s Traffic Engineer. The compressor has already been placed on the well pad for storage purposes but has not been installed. D. Road Dedication No new public roads are being built or dedicated as part of this project. E. Impacts Mitigated County roads will experience minor impacts during installation from this project that are characteristic of natural gas development in the region. No formal mitigation will be required for this project. See the Traffic Study for further information. F. Design Standards As stated above, no new roads are being built as part of this project. Existing access route(s) already conform to the standards of Table 7-107. SECTION 7-108. USE OF LAND SUBJECT TO NATURAL HAZARDS According to the Geologic Hazard Report, the project area is not subject to rock fall, snow slides, mud flows, radiation, flooding, or high water tables. The site is located on pre-historic earthflow and soil creep deposits having the potential to be a geologic hazard affecting the Site. There are existing wells on the location and there is other development in the area. No flood prone areas are mapped in the vicinity of the site. Flash flooding is an issue for lower elevations along Dry Creek and areas along the Colorado River located to the north and west are prone to flood risks. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 4 There are no mining activities shown in the vicinity of the site. Natural gas well drilling has been conducted in the area since the 1960s. There are no significant radioactive mineral deposits known in the immediate area of the site. The presence of NORM may be an issue with exploration and production and could be an issue with used pipe scale or used equipment, but radioactive materials are not expected to pose a significant hazard at the Site. SECTION 7-109. FIRE PROTECTION A. Adequate Fire Protection The proposed booster compressor is located within the Grand Valley Fire Protection District. The District is aware of the well pad location and can provide adequate fire protection/response. Ursa is willing to provide training to the District regarding the site operations, if requested. B. Subdivisions This standard does not apply as the proposed land use is not a subdivision nor located within a subdivision. DIVISION 2. GENERAL RESOURCE PROTECTION STANDARDS SECTION 7-201. AGRICULTURAL LANDS A. No Adverse Affect to Agricultural Operations The operation of the proposed booster compressor will not adversely affect agricultural operations on the subject property or adjacent lands. B. Domestic Animal Controls The operation of the proposed facility will comply with this standard. No domestic animals are allowed on the site. C. Fences The facility will not generate a potential hazard to domestic livestock or wildlife. No open storage of hazardous materials or attractions will be conducted on the site. D. Roads The proposed facility will not impact adjoining roadways beyond current impacts due to the anticipated low operational traffic volumes. The Project Description, Traffic Study, and Road Assessment Report describe the proposed access. Additional details are shown on the site plan. The proposed booster compressor facility will not require construction of new roads. The use will utilize the existing access from CR 300 to Daybreak Drive. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 5 E. Irrigation Ditches No irrigation ditches are adjacent to the proposed booster compressor site. Implementation of the engineered grading and drainage plan and conformance with stormwater best management practices will assure that any irrigation ditches on the subject parcel will not be impacted by the facility. SECTION 7-202. WILDLIFE HABITAT AREAS A. Buffers The proposed booster compressor is located on an existing well pad. No new surface disturbance will be required. The area immediately surrounding the Speakman A pad consists of former pinyon-juniper woodland and sagebrush rangeland that has historically been developed for agricultural purposes (hay pasture). B. Locational Controls of Land Disturbance The proposed booster compressor is located on an existing well pad. No new surface disturbance will be required. No migration corridors are affected. Human presence and activity may affect animal distribution by creating avoidance areas and increasing stress on wintering big game. Over time, deer and elk that winter in this area have become habituated to human activity and the indirect effects of avoidance and displacement have decreased. Vehicle traffic could result in vehicle related wildlife mortality, although no additional traffic resulting from this project is expected. Traffic volumes and speed on the private road accessing the site are unlikely to result in significant animal mortality from vehicles. Fences can pose an increased risk to big game. Any fencing around the facility would be constructed according to published standards that reduce impacts to big game. Equipment is outfitted with bird cones to prevent perching. C. Preservation of Native Vegetation 1. No additional vegetation removal will be necessary for installation of the booster compressor since it will be placed on an existing natural gas well pad. 2. Application of the Integrated Vegetation and Noxious Weed Management Plan (IVNWMP) and Ursa’s Noxious Weed Management Plan will provide a degree of mitigation for the native vegetation that has already been removed. Ursa will also comply with COGCC Rule 1002 regarding revegetation and control of noxious weeds. Evidence of weed control is included in the application package. 3. Vehicles and equipment traveling from weed-infested areas into weed-free areas could disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed-free areas. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 6 Several simple practices will be employed to prevent most weed infestations. The following practices have been adopted to reduce the costs of noxious weed control through prevention. The practices include:  Prior to delivery to the site, equipment should be thoroughly cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds.  If working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain.  All maintenance vehicles should be regularly cleaned of soil.  Avoid driving vehicles through areas where weed infestations exist. D. Habitat Compensation Placement of this project within the boundaries of an existing development has resulted in avoidance of additional contributions to cumulative effects of habitat alteration and fragmentation in the region. The development of the project is not expected to significantly affect any critical environmental resources. Ursa has a Wildlife Mitigation Plan in place with the Colorado Division of Parks and Wildlife. E. Domestic Animal Controls Livestock and big game will likely avoid the project site. Dogs and other domestic animals are not allowed on site. SECTION 7-203. PROTECTION OF WATERBODIES A. Minimum Setback 1. The eastern edge of the project site disturbance is more than 35 feet from the Ordinary High Water Mark (TOHWM) of the natural drainage that runs south to north to the east of the proposed booster compressor. 2. There are no entrenched or incised streams on or adjacent to the proposed project site. 3. No hazardous material will be stored on the project site. Please see SPCC Plan included in this submittal for measures to protect surface and ground water from spills. B. Structures Permitted in Setback No structures will be located within the 35 foot setback. C. Structures and Activity Prohibited in Setback No structures will be located within the 35 foot setback . No work of any kind will occur within the 35 foot setback. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 7 D. Compliance with State and Federal Laws The proposed booster compressor will not impact any Waterbody of the US. SECTION 7-204. DRAINAGE AND EROSION A. Erosion and Sedimentation The proposed booster compressor will not require clearing or vegetation removal beyond the existing well pad and previously disturbed area. BMPs such as sediment basins, top soil berms, and ditches will be utilized to ensure the continued protection of water bodies from stormwater runoff during construction and operation of the well pad. B. Drainage 1. This standard requires that lots be laid out to provide positive drainage. Lots are not proposed as part of this land use application. The proposed project will not create any impacts to existing drainage patterns. 2. This standard also addresses individual lot drainage within a residential development and is not applicable to this use. The proposed facility will not impact natural drainage patterns. C. Stormwater Run-Off The site has been designed to COGCC standards for stormwater management to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation. BMPs will be maintained until the facility is abandoned and final reclamation is achieved pursuant to COGCC Rule 1004. The well pad is at times within 100 feet of a Waterbody, but it will not create 10,000 square feet or more of impervious surface area. 1. Avoid Direct Discharge to Streams or Other Waterbodies. Stormwater Runoff from the project areas will be controlled by use of BMPs such as sediment basins, top soil berms, and ditches. 2. Minimize Directly-Connected Impervious Areas. The site design will not create more than 10,000 square feet of impervious surface area. 3. Detain and Treat Runoff. Ursa has incorporated a number of stormwater detention facilities into the design for this site. Stormwater runoff will be controlled via a combination of sediment basins, top soil berms, and ditches. a. Due to the low imperviousness of the historic and existing basins, and the reduced tributary basin size of the gas pad development, no 25-year event detention is required for the site. The Erosion and Control Plans show a measure of pipe outlet and inlet protection, sediment traps, and ditches proposed for the construction of the pad. These are typical with grading construction associated with oil and gas pads in Garfield County. This pad has gone through construction and interim stabilization for the stormwater permitting process and no further stormwater Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 8 controls are necessary. The pad is currently operating under guidelines established by Ursa for spill containment and incident isolation. b. The project site is above the 100- and 500-year floodplain of the Colorado River, therefore a 100-year storm event should not cause property damage. c. Channels downstream from the stormwater detention pond discharge have been designed to prevent increased channel scour, bank instability, and erosion and sedimentation from the 25-year return frequency, 24-hour design storm. d. The size and design of drainage facilities are based on COGCC Section 800 rules and CDPHE stormwater regulations and permit conditions. The site is already constructed. e. All culverts, and drainage pipes, utilized at this facility are designed and constructed according to the AASHTO recommendations for a water live load. SECTION 7-205. ENVIRONMENTAL QUALITY A. Air Quality Ursa will obtain all required air permits or APENs for the booster compressor. Any equipment that emits greater than two tons per year of criteria pollutants will need an APEN. Ursa has approved GP01 and GP05 General Permits for the Speakman A Pad condensate and produced water tank batteries. A revised Air Quality Permit will be required for the Speakman a Booster Compressor. Ursa has 30 days from the date the compressor goes online to evaluate the potential to emit and update their permit. A copy of the approved permit will be forwarded to Garfield County as soon as it is approved. B. Water Quality No hazardous materials will be stored on site. An SPCC plan is in effect for the tank batteries associated with the well pad. A copy of the plan is included with this submittal. SECTION 7-206. WILDFIRE HAZARDS A. Location Restrictions The proposed booster compressor facility is not located in an area designated as a severe wildfire hazard area according to the Garfield County on-line GIS map resources, nor is it located within a fire chimney or an area of high wildfire risk as identified by the Colorado State Forest Service. B. Development Does Not Increase Potential Hazard The proposed booster compressor will not increase the potential intensity or duration of a wildfire, or adversely affect wildfire behavior or fuel composition. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 9 C. Roof Materials and Design Roof materials for any building on the well pad are made of noncombustible materials. Any proposed construction will comply with requirements of the 2009 International Fire Code. SECTION 7-207. NATURAL AND GEOLOGIC HAZARDS A. Utilities Geological hazards are not expected to be associated with the installation of buried utilities. Slopes may be a limitation to this construction, but this limitation should be able to be overcome with proper engineering, design, and construction. The compressor will be installed on a previously disturbed cut portion of the well pad, so slopes are no longer a limitation. B. Development in Avalanche Hazard Areas Avalanche conditions are not expected to be present in area of the site. C. Development in Landslide Hazards Areas The site is located on pre-historic earthflow and soil creep deposits having the potential to be a geologic hazard affecting the site. There are existing wells on the location and there is other development in the area. No additional soil disturbance is anticipated for the installation of the proposed booster compressor. D. Development in Rockfall Hazard Areas Rockfall areas are not present in the vicinity of the site. Rockfall areas are present in parts of the steep canyons and narrow drainages incised by area streams, but are not expected to be a hazard in the vicinity of the Site. E. Development in Alluvial Fan Hazard Area The Site is not in an alluvial fan hazard area. Alluvial fans are present to the northwest between the site and the Colorado River drainage. F. Slope Development Slope is a limitation associated with the Potts and the Potts Ildefonso complex soils and certain types of development. The Speakman A Booster Compressor is not expected to be adversely affected by the slopes in the area. G. Development on Corrosive or Expansive Soils and Rock Corrosive or expansive soils and rock are not expected to be present in the vicinity of the proposed booster compressor. Rocky soils may exist in the vicinity of the site which may impact the proposed development. The booster compressor is skid mounted, so a foundation is not required. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 10 H. Development in Mudflow Areas Collapsible soils are not present in the vicinity of the well pad site. I. Development Over Faults No significant faulting is known in the vicinity of the Speakman A well pad. SECTION 7-208. RECLAMATION A. Applicability No Individual Sewage Disposal System (ISDS) will be installed. No new access is being proposed. The booster compressor will be installed on a previously approved COGCC well pad. Ursa will abide by all reclamation requirements set out by COGCC Rules 1003 and 1004 for interim and final reclamation. All of Ursa’s surface disturbances are covered under a statewide bond, held by the COGCC. A copy is included in the Reclamation Plan section. B. Reclamation of Disturbed Areas A copy of Ursa’s Reclamation Plan is included in this submittal. Areas disturbed during the development of the well pad will be restored as natural-appearing landforms that blend in with adjacent undisturbed topography at the end of the life of the well pad. 1. Contouring and Revegetation. Areas disturbed by grading will be contoured so they can be revegetated as appropriate for interim and final reclamation. At the end of the life for the well pad, it will be revegetated and monitored until 70% coverage is attained, using species as noted in the accompanying Reclamation Plan. 2. Application of Top Soil. Top soil was stockpiled as berms around the perimeter of the well pad. Unused top soil has been stockpiled and vegetated temporarily to reduce erosion until it can be reused during reclamation. 3. Retaining Walls. No retaining walls are planned for this project. 4. Slash Around Homes. No residences will be part of the proposed project. 5. Removal of Debris. The proposed booster compressor is located on an existing natural gas well pad. 6. Time Line Plan. The site will be reclaimed in 20-50 years, at the end of the life for the natural gas wells serving the booster compressor. DIVISION 3. SITE PLANNING AND DEVELOPMENT STANDARDS SECTION 7-301. COMPATIBLE DESIGN Operation of the proposed facility will be consistent with nearby uses. The majority of the adjacent properties are currently occupied by residential uses, small ranches, and oil and gas Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 11 development. The facility will be unmanned, except during times of maintenance. There will be minimal impacts to the existing roadway system during the operational phase. A. Site Organization The site has one access point to Daybreak Drive at the southern end of the project site. The site will be organized to provide safe access to and from the site and parking off the public right-of-way. It will not disrupt solar access to adjacent properties, pedestrian access, nor access to common areas along Daybreak Drive. B. Operational Characteristics 1. Adjacent lands will not be impacted by the generation of vapor, odor, smoke, glare, noise or vibration beyond the impacts already associated with the operation of the existing natural gas well pad. Generation of dust will be mitigated by use of water or other additives to the road ways to decrease/prevent the generation of dust caused by vehicles accessing the well pad. 2. The motor for the booster compressor is powered by natural gas. In order to mitigate potential sound levels which could impact nearby residences, an acoustical barrier will be installed along the northeast and a portion of the northwest sides of the compressor. The sound pressure levels extrapolated for the Speakman A site are calculated and actual noise levels will vary. The actual sound pressure levels will be measured during equipment operation to ensure regulatory compliance. Ursa will install additional mitigation, if necessary. 3. The compressor will run 24 hours a day, seven days a week. Maintenance on the compressor will typically be done during daylight hours between 7:00 AM and 7:00 PM. C. Buffering The well pad where the proposed booster compressor will be located is buffered to mitigate visual and noise impacts to adjacent property. D. Materials Equipment and sound walls will be painted to blend in with the surrounding landscape. SECTION 7-302. OFF-STREET PARKING AND LOADING STANDARDS Adequate parking will be made available to accommodate Ursa personnel during regular operation, inspection, and maintenance of the facility. All activities on this site will be conducted out of any public right-of-way. All off-loading and loading will take place on the well pad out of the public right-of-way. See Site Plan for vehicle circulation. Loading and unloading of vehicles will take place in a manner that will not interfere with the flow of traffic on Daybreak Drive or County Road 300. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 12 Parking and loading surfaces have been designed by an engineer to ensure proper drainage of surface water and stormwater. See Grading and Drainage Plan section of this submittal. Traffic circulation patterns on site will be such that no vehicle will be required to back on to the public right-of-way. The access driveway for the proposed booster compressor runs to the south off of the well pad to Daybreak Drive. The apron to the Daybreak Drive is constructed to accommodate the tanker trucks typical for hauling produced water for the injection well on the site. The driveway has a clear vision area of 300 feet to the east and west. See the Traffic Study for more information. A. Parking and Loading Area Landscaping and Illumination No landscaping is planned for the proposed project site. Any illumination will be downcast, shielded, and directed inward per Garfield County standards. Employees will be reminded to direct movable light plants at the work being done. SECTION 7-303. LANDSCAPING STANDARDS This type of industrial use is exempt from the landscape standards of the Development Code. SECTION 7-304. LIGHTING STANDARDS A. Downcast Lighting Any lighting will be directed inward, towards the interior of the site. B.

Hazardous Lighting Light from the site will not create a traffic hazard or be confused as traffic control devices. D. Flashing Lights The facility will not contain flashing lights. E. Height Limitations There will be no light sources exceeding 40 feet in height on the site. SECTION 7-305. SNOW STORAGE STANDARDS Snow will be stored in a vacant section of the existing disturbed area. The site has been graded to accommodate snowmelt to insure sufficient drainage. Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 13 SECTION 7-306. TRAIL AND WALKWAY STANDARDS A. Recreational and Community Facility Access The proposed site is located in a rural area of Garfield County. A connection to public facilities is not appropriate or feasible. DIVISION 10. ADDITIONAL STANDARDS FOR INDUSTRIAL USES SECTION 7-1001. INDUSTRIAL USE A. Residential Subdivisions This site is not located in a platted residential subdivision. B. Setbacks The proposed booster compressor is located more than 100 feet from all adjacent property lines. C. Concealing and Screening This site is located in a rural area. Aboveground facilities will be managed to minimize visual effects (e.g. painted to blend with environment). D. Storing All products will be stored in compliance with all national, state and local codes and will be a minimum of 100 feet from adjacent property lines. E. Industrial Wastes All industrial wastes will be disposed of in a manner consistent with federal and state statutes and requirements of CDPHE and COGCC. F. Noise The booster compressor is being installed to lower the noise levels produced by the existing six well head compressors. The occasional pickup truck for maintenance and monitoring purposes will not impact surrounding operations and properties beyond the impacts of the current natural gas operations on the well pad. The motor for the booster compressor is natural gas powered. In order to mitigate potential sound levels which could impact nearby residences, an acoustical barrier will be installed along the northeast and a portion of the northwest sides of the compressor. The extrapolated sound pressure level averages at all nearby occupied structures is calculated well below the 50 dB(A) limit. The sound pressure levels extrapolated for the Speakman A site are calculated and actual noise levels will vary. The actual sound pressure levels will be measured during equipment Ursa Operating Company, LLC Speakman A Booster Compressor Standards Analysis Page 14 operation to ensure regulatory compliance. Ursa will install additional mitigation, if necessary. G. Ground Vibration Ground vibration will not be measurable at any point outside the property boundary. H. Hours of Operation The facility will not generate noise, odors, or glare beyond the property boundaries greater than what is allowed under the Land Use Development Code. The compressor will run 24 hours a day, seven days a week. Maintenance on the compressor will typically be done during daylight hours between 7:00 AM and 7:00 PM. I. Interference, Nuisance, or Hazard Adjacent lands will not be impacted by the generation of vapor, dust, smoke, noise, glare, or vibration beyond those impacts of the current natural gas activities taking place on the well pad. Ursa will apply the appropriate level of controls to accommodate potential impacts via adherence to CDPHE Air Quality regulations and the implementation of industry BMPs included in the SWMP and Ursa’s dust control plan. The pad and access road will be graveled to reduce fugitive dust, which will be controlled using water or other dust suppressants. In order to mitigate potential sound levels which could impact nearby residences, an acoustical barrier will be installed along the northeast and a portion of the northwest sides of the compressor. The extrapolated sound pressure level averages at all nearby occupied structures is calculated well below the 50 dB(A) limit. The sound pressure levels extrapolated for the Speakman A site are calculated and actual noise levels will vary. The actual sound pressure levels will be measured during equipment operation to ensure regulatory compliance. Ursa will install additional mitigation, if necessary.
