ZONING: Rural (R) TYPE OF APPLICATION: Administrative Review-Injection Well, Small (less than 5,000 bbls of on pad tank storage) I. GENERAL PROJECT DESCRIPTION This proposal is for the drilling of an injection well on the proposed Watson Ranch B Pad. The injection well will be operated by Ursa Operating Compa ny. The pad is proposed to be 6.43 acres in size and will have access off of County Road 303 via an existing driveway currently serving an adjacent well pad. A road extension of approximately 700 ft. will be constructed to the new pad. The Watson B Pad will be developed as double pad and will have approximately 40 gas wells in addition to the injection well. The injection well will serve 2 - 3 other well pads and will have water for disposal/injection primarily pumped to the site via pipelines. It is estimated that 90% of the water will be received by pipeline with trucking minimally utilized. Preliminary plans indicate that storage on site will be approximately 1800 bbls . Equipment on site will be typical for well production and injection well facilities. Timing for operation of the well is estimated for late fall, 2015. The well pad will be developed in accordance with COGCC Permitting requirements . Additional COGCC review and forms for the injection well will be required. COGCC permitting addresses and monitors water sources, well injection zones and capabilities of the well for injection. In regard to the water issues the Application should demonstrate compliance with all Division Water Resources regulations (including CRS 37-90-137). Information on other typical industrial impacts (noise, traffic, air quality) should all be provided. Stormwater Management Improvements and BMP's should be addressed and are anticipated to be in place on the well pad. The Application needs to demonstrate compliance with the County Roadway Standards contained in Table 7-107. A traffic analysis to address any off-site impacts and County Road impacts is also needed. The Applicant should confirm that COGCC reclamation bonds will be in place. The site plan mapping should include a surveyed description of the site along with the legal description for the overall tract. The property owner is technically required to be the Applicant so the Application will need to include evidence of authorization for the operator to represent the owners which may include lease agreements and related documentation.

Section 7-107 Access and Roadways F. Design Standards. Roadways, surfaces, curbs and gutters, and sidewalks shall be provided as follows (see Table 7-107: Roadway Standards): A waiver of standards request shall be considered based on the following criteria: 1. Achieves the intent of the subject standard to the same and better degree than the subject standard: Response: The roadway deviates from the Design Standards in Table 7-107 for ROW width, shoulder width, ditch width, cross slope, shoulder slope and surface. The road is across private land and currently is not covered by a dedicated access easement or dedicated right-of-way (ROW). The road width varies between 16 feet and 37 feet. The portion of the roadway that is 16 feet in width does not allow for a shoulder width of 2 feet minimum. However, there is sufficient width to allow for two-way traffic in most areas, and in other areas, there is sufficient width to allow for a parked vehicle to wait while a vehicle traveling in the opposing direction passes prior to entering the portion of the roadway that is narrower. Roadside ditches were not constructed and are not shown within the improvement plan for the proposed roadway. The existing roadway allows for storm drainage to sheet flow across the roadway. The proposed roadway design intent appears to mimic the pattern of the existing roadway. The existing cross slope and shoulder slope varies between 1% and 2.8%. The proposed cross slope is anticipated to be constructed as 3%; however, the improvement plan for the proposed roadway does not include a typical section. The road geometry changes occasionally with maintenance activities. While ponding may occur in areas of shallow cross slope, the road is inspected on a regular basis for maintenance issues, which are addressed in a timely manner. The anticipated road surface of the proposed roadway is gravel; however, the improvement plan does not include a typical section. Ursa Operating Company LLC Watson Ranch B Injection Well Waiver Requests Page 2 The road functions adequately as built and is typical of existing roads providing access to natural gas production in Garfield County. 2. Imposes no greater impacts on adjacent properties than would occur through compliance with the specific requirements of this Code. Response: Full compliance with the ROW, shoulder, and ditch standards would require that the road be widened, causing additional disturbance to reconstruct the road and redesign the current drainage. This would require additional encroachment on to the lessor’s property. It is difficult to maintain the cross slope and shoulder slope over the life of the roadway. The road geometry changes occasionally with maintenance activities. While ponding may occur in areas of shallow cross slope, the road is inspected on a regular basis for maintenance issues, which are addressed in a timely manner. These deficiencies do not impose any impacts on adjacent properties beyond those would occur through compliance with the standards. Pursuant to Section 4-202 of the Garfield County Land Use and Development Code, Ursa Operating Company LLC (Ursa) requests a waiver for the submittal requirement of a Development Agreement and an Improvements Agreement for the Watson Ranch B Injection Well. Section 4-203.J. Development Agreement A waiver request shall be considered based on the following criteria: 1. The Applicant shows good cause for the requested waiver; Response: Ursa Resources wishes to neither propose a phasing schedule nor extend establishment of vested property rights. 2. The project size, complexity, anticipated impacts, or other factors support a waiver; Response: The proposed injection well facility will be located on a COGCC approved natural gas well pad. The well will be drilled as part of the well pad development. 3. The waiver does not compromise a proper and complete review; and Response: The Administrative Review request can be properly and completely reviewed without a development agreement. 4. The information is not material to describing the proposal or demonstrating compliance with approval criteria. Response: A development agreement is not material to describing the purpose, operation and maintenance of the facility or demonstrating compliance with applicable approval criteria. Ursa Operating Company LLC Watson Ranch B Injection Well Waiver Requests Page 3 Section 4-203.K. Improvements Agreement A waiver request shall be considered based on the following criteria: 1. The Applicant shows good cause for the requested waiver; Response: No public improvements are being proposed that would warrant the creation of an improvements agreement. 2. The project size, complexity, anticipated impacts, or other factors support a waiver; Response: As stated above no public improvements are being proposed with this request. 3. The waiver does not compromise a proper and complete review; and Response: The application can be properly and completely reviewed without an improvements agreement. 4. The information is not material to describing the proposal or demonstrating compliance with approval criteria. Response: An improvements agreement is not material to describing the purpose, operation and maintenance of the facility or demonstrating compliance with applicable approval criteria.

Ursa is requesting this permit under the “Injection Well, Small” land use that is an allowed use in the Rural zone district. The water to be handled at this facility is produced from drilling, completion and production operations associated with natural gas wells. Water that is produced from these operations is classified as an exploration and production (E&P) waste by the Colorado Oil and Gas Conservation Commission (COGCC). The proposed facility will dispose of and store water only from Ursa’s holdings. Fluids will be delivered to the facility via tanker trucks using Garfield County approved haul routes from the B&V, Richardson, Speakman, Stierberger, and Tompkins well pads. Pipelines will serve the Monument Ridge, Yater, and Watson Ranch A well pads. Ursa may construct additional pipelines to deliver fluids from the well source(s) to the injection well. The proposed facility will be located on a well pad approved by the COGCC. In addition to being permitted pursuant to COGCC Rule 325, the proposed facility will be permitted according to COGCC Forms 31 and 33 for injection wells as well as COGCC Form 26 for source of produced water. All of Ursa's surface disturbances (final reclamation requirements) are covered under a statewide bond held by the COGCC. A copy of Ursa’s Blanket Surface Bond #2012-0126 is included in the Reclamation Plan section. The facility will consist of the following equipment: one (1) injection well, one battery of storage tanks to be dedicated to the disposal facility (6 tanks total) with an approximate total volume between 1,800 and 3,000 bbls with a 3-foot high containment wall area around each tank battery, two (2) combustors, a valve set and a maximum 20 foot by 50 foot building for the electric pumps. The site perimeter will have an earthen berm a minimum of 2-feet high. The site for the proposed Ursa Watson Ranch B Injection Well is approximately 1.5 miles south of the Battlement Mesa, Colorado on County Road (CR) 303 (Gardner Lane) in the SE ¼ of the SW ¼ of Section 17, Township 7 South, Range 95 West of the 6th P.M.. The site encompasses approximately 6.43 acres, at an elevation of 5,585 feet. The property is owned by a Watson Ranches, LLC and leased to Antero Resources through a Surface Use Agreement (SUA), dated January 26, 2011. Antero’s Piceance Basin assets were purchased by Ursa. Additional SUAs between Watson Ranches and Ursa are included with this submittal. The proposed facility will be operated exclusively by Ursa. The proximity of Ursa’s operations to the proposed injection well necessitates the construction of this facility, so that water produced during the drilling, completion and production of natural gas wells in the area may be collected and disposed of in a centralized Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 2 location. Operation and monitoring of the facility will not require any additional equipment other than what is outlined above. Monitoring of operations will typically be performed periodically during the daylight hours of 7:00 am to 6:00 pm by an Ursa employee arriving via pickup truck. A dust control program will be implemented for the construction interval and use of the access road. The proposed facility will not impact groundwater due to engineering design of the injection well and the depth at which fluid will be injected. As part of the Garfield County permit approval process, Ursa will secure all appropriate Colorado Department of Public Health and Environment (CDPHE) air quality (AQ) permits for the storage tanks. The approved Air Quality permit also will address the impacts and appropriate level of mitigation for the facility associated with fugitive dust and hydrocarbon venting from the facility. A copy of the CDPHE AQ approvals will be provided upon receipt. The key benefits of the proposed project are:  Minimize impacts to wildlife and vegetation by constructing a facility on previously disturbed surface  Reduce road maintenance  Utilize an engineering controlled transfer system onsite to minimize human error  Reduce Ursa’s overall development and operating cost by negating the requirement for transport and fluid disposal at distant locations  Ultimately, construction of the pipeline network will further reduce trucking/improve safety Details of this request along with the information required by GARCO’s Administrative Review application are provided below. The majority of the adjacent properties are currently occupied by residential uses, PUD open space, small ranches, agricultural land, and oil and gas development. The nearest municipality is the Town of Parachute and the Battlement Mesa Planned Unit Development, approximately 1.5 miles to the north. There are several residences located within 1,500 feet of the site (See Adjacent Uses Map). Copies of deeds demonstrating ownership of this property are contained in the Deeds section. The edge of the disturbance for the well pad and proposed injection well facility is located approximately 90 feet from the northern boundary and approximately 92 feet from the eastern boundary of the property owned by Watson Ranches, Ltd and leased by Ursa. The western and southern property boundaries are more than 200 feet from the edge of the pad disturbance. As part of the GARCO Administrative Review approval process, proper notification will be provided to all appropriate landowners and mineral owners. The list of landowners and mineral owners that will be sent certified letters informing them of the proposed project and decision date are included as part of the overall GARCO Administrative Review submittal package. The design for the proposed facility is provided in the facility site diagram and construction documents. Stormwater management protections, specific best management practices (BMPs) Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 3 and other drainage controls have been designed into the facility. The facility will be constructed according to the criteria identified in the COGCC Rule 325. The injection well facility will be accessible to Ursa personnel and their contractors 24 hours-a- day, 365-days-a-year. Daily inspections will be conducted by local operations personnel. Operations and maintenance of the proposed facility will be coordinated with the existing operations in the area. An analysis of the traffic impacts generated by this project is provided in the Traffic Study section. The project will be developed in one (1) phase and will include:  Six storage tanks totaling between 1,800 and 3,000 bbls.  Injection pump  Associated piping It is anticipated that one pump will supply fluids to the proposed injection well. Therefore, Ursa is requesting approval for one pump and the necessary associated equipment. The injection pump will be powered by electricity. A copy of the “Will Serve” letter from Holy Cross is included in the Standards section of the application. Delivery of fluids to the proposed facility could come from several of Ursa’s well pads, including Yater, Watson Ranch, Monument Ridge, Watson Ranch B, Speakman A, Speakman B, B&V, Stierberger, Richardson, and Tompkins. Produced water from the aforementioned sites may be delivered to the existing Speakman A and the proposed Watson Ranch B injection wells. Water from Speakman A and Speakman B pads will rarely be transported to the Watson Ranch B site. The originally permitted Watson Ranch location (sometimes referred to as “Watson Ranch A”) is located adjacent to Watson Ranch B and thus will deliver water to Watson B via pipeline. There is an existing pipeline that will provide water transport from Monument Ridge to Watson Ranch. After the Yater location is constructed, a water pipeline will also connect the Yater site to the Watson Ranch B location. Ultimately Ursa hopes to connect all of their production facilities to injection well(s) via pipeline. In the interim, the B&V, Stierberger, Richardson, and Tompkins pads will deliver water via trucks using the Garfield County Road and Bridge approved haul route. A full traffic impacts analysis has been provided as part of this submittal. Ursa’s inspector has been contracted to inspect all sites on a monthly basis for adherence to state and federal requirements. The inspector will maintain monthly logs to accommodate maintenance, safety and regulatory requirements. The facility will not require potable water or human waste disposal. No lighting will be required at the facility. Fluids will be transported to the facility for underground disposal via water truck or pipeline. Drawings showing Ursa’s origination of produced water from the Williams Fork formation, location of Ursa well pads and Ursa leasehold locations associated with the proposed injection well are included in the application package. Additionally, a spreadsheet list of all of Ursa’s COGCC approved well pad and well locations are included in the application package. If approved by Garfield County, the injection well will be appropriately permitted through the COGCC Form 31 and Form 33 process. This process reviews the formation into which water is Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 4 to be injected and all underground sources of drinking water which may be affected by the proposed operation. The COGCC requires a water analysis and a fracture pressure or fracture gradient analysis of the injection formation. If remediation is required for drinking wells within a quarter of a mile of the injection well, a remediation plan must be filed with the COGCC. The facility will be operated in accordance with the conditions dictated by the COGCC permitting/approval process. The construction of the well casing is highly regulated by the COGCC who requires a resistivity log and full description of the casing of the well. The minimum and maximum amounts of water to be injected daily with anticipated injection pressures is required to be reported to the COGCC at the time of permitting. Prior to application approval, the proposed disposal well must satisfactorily pass a mechanical integrity test. The proposed injection well must continue to pass mechanical integrity testing throughout the life of the well. Environmentally sound and safe operation of the proposed injection well is assured with the implementation of the following emergency controls:  Bradenhead Pressure Alarm: monitors surface casing pressure  Wireless Casing Pressure Monitor/Transmitter: monitors casing pressure  Wireless Tubing Pressure Monitor/Transmitter: monitors tubing pressure  Remote Shut Down Controls: the injection well is equipped with a stand-alone remote telemetry (shutdown) unit that would allow the injection well to continue to operate (but shut down if any alarms or operational issues occur) in the event that the operator loses contact with the injection well; it is solar powered and has a backup battery power supply. Each control is designed to notify the operator regarding any issues with the injection well and, the controls have the capability to remotely shut down the well, without operator assistance. In addition to the injection well controls listed above, Ursa will have additional controls, which consist of:  Pump(s) supporting the injection well are equipped with Programmable Logic Controls, which monitors the pump package and pressures.  The pump(s) are also equipped with Low Oil Level Alarms and high and low tank alarms. The equipment also monitors flow rates, including the maximum daily pressure/volume (as set by the COGCC). Estimated trip generation information is provided in the Basic Traffic Analysis report included in this submittal. All vehicles hauling equipment and material for project construction on Garfield County roads will abide by Garfield County Road and Bridge’s oversize/overweight regulations. All construction and operations personnel will park on the proposed site and will not block or hinder normal traffic on County Road 303. All activities on this site will be conducted out of the Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 5 right-of-way of County Road 303 on the subject parcel, and all loading and unloading of vehicles will be conducted out of the public right-of-way. As discussed in previously, the construction of this facility will result in minor, temporary increases in traffic on approved haul routes around Battlement Mesa. After the complete installation of the pipeline network that will deliver fluids to the facility, there will be a significant reduction in tanker truck traffic required to haul water from/to Ursa’s operations. Regardless of the traffic volume, Ursa will implement the following measures, as necessary, to minimize impacts to transportation and roads:  Control dust along unsurfaced access roads and minimize tracking of soil onto paved roads, as required by the CDPHE Construction Stormwater Permit and per the details contained in the Dust Control Plan.  Comply with county and state weight restrictions and limitations.  Limit construction and operation traffic speeds to a low and reasonable level.  Keep dusty, exposed areas damp with water or a magnesium-chloride solution or other dust suppressant.  Stabilize traffic areas with gravel.  Revegetate or stabilize non-traffic areas as soon as practicable. The proposed injection well facility will comply with all of Ursa’s safety practices including emergency response procedures. The proposed site will comply with requirements of the International Fire Code 2003 Edition, as applicable. A copy of Ursa’s Emergency Response Plan, which includes emergency contact numbers, is provided as part of the submittal. The overall strategic objectives in any emergency response will be to maximize personnel and public safety. Electrical power will be supplied on-site via an agreement with Holy Cross Energy. Operation of the facility will comply with the appropriate Colorado air emissions permitting regulations. Storage tanks in excess of 1,320 gallons that contain hydrocarbon liquids will be included in the area wide Spill Prevention Control and Countermeasures (SPCC) plan. A Stormwater Management Plan (SWMP), detailing the use of site-specific BMPs, has been prepared for this area. Further, the SWMP is being updated to reflect changes to Ursa’s stormwater plan. All updates to the SWMP will be completed prior to initiating any construction activity. Implementation of the SWMP and the appropriate BMPs will ensure that activities conducted at the site comply with stormwater management regulations as required by Garfield County, the State of Colorado, and the United States Environmental Protection Agency. Implementation of this plan also ensures that installation and operation of this facility will not impact surface runoff, stream flow, or groundwater. Site specific BMPs implemented to accommodate erosion control will include (but not be limited to) the following: sediment basins, bales, silt fencing, straw wattles, check dams and berms. Copies of the current SWMP and permit are included in this submittal. The CDPHE anticipates updating its rules regarding Stormwater permits. All permits issued prior to 6/30/2012 were set to expire on 6/30/2012 and were administratively continued indefinitely via a letter from CDPHE. Permits issued after 6/30/2012 Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 6 show an expiration date of 6/30/12 and the comment ADMINISTRATIVELY CONTINUED on the permit certificate with no further expiration date. No additional documentation is required now. No flammable or explosive solids or gases will be stored on site. Maps detailing the locations of wells that could contribute water to the proposed injection well are attached. These maps demonstrate that the wells are located within the non-tributary designation of the Williams Fork formation per data available from the Colorado Division of Water Resources (CDWR). As required by COGCC rules, all spills and releases from this facility will be reported to the COGCC in accordance with Rule 906. In the event that a reportable spill or release does occur, Ursa will notify all agencies as required by the COGCC. A Noxious Weed Management Plan is included in this submittal. In addition to the measures that are outlined in this plan, Ursa will implement other measures to prevent infestation of noxious weeds. These measures typically include seeding cut and fill slopes around the facility to reestablish native vegetation. The potential impacts to wildlife from this facility are anticipated to be negligible as discussed in the Impact Analysis: Section 4-203-G (8) Environmental Impacts and the Section 7-202 Protection of Wildlife Habitat Areas reports provided as part of this application. These reports also discuss several mitigation measures that could be employed to further minimize wildlife impacts. The facility design will also ensure that the environment is protected at all times through engineered controls and equipment. Ursa has a Wildlife Mitigation Plan approved by Colorado Parks and Wildlife (CPW) that addresses financial and field best management practices (BMPs) within the area of the proposed project. Additional details are provided in this application’s Impact Analysis (IA) section. Because of the minimal activity and equipment associated with operation of this facility, no smoke, vibration, heat, radiation or fumes will be produced as a result of the operation of this facility, beyond that caused by COGCC approved drilling and completion activities.. Any appropriate air quality notices and/or permits will be secured from the CDPHE as required. The injection well will not require an air quality permit or Air Pollution Emissions Notice (APEN). Any associated equipment that emits greater than two tons per year criteria pollutants, i.e. production tanks, will need an APEN. The injection well will be fed by an electric pump. This pump is exempt from an air permit/APEN. The only APEN required for the Watson Ranch B injection well facility is specific to the injection well storage tank battery. Ursa will obtain the appropriate air quality permits prior to commencing operation of the injection well. Lighting will only be required during unscheduled nighttime maintenance activities. The facility will be operated in compliance with the noise standards set forth in the Colorado Revised Statutes for Residential/Agricultural/Rural zones. During operation of the facility, contributions to the background noise levels will be negligible. Adjacent property will not be Ursa Operating Company, LLC Watson Ranch B Injection Well Project Description Page 7 affected, and a public nuisance or hazard will not be created. It is not anticipated that operation of the pumps at the facility will create a nuisance, since they will be located inside a metal fabricated building. Solid waste refuse generated during the construction and operational activities will be stored in wildlife proof containers provided by a licensed refuse hauler. Ursa will use a refuse hauling service to empty the refuse receptacle. Receptacles will be emptied as needed and disposed of at the Garfield County Landfill or other permitted facility. Ursa’s refuse hauler will maintain all records including, but not limited to, trip logs/reports and landfill receipts, and all records will be available to the County upon request. The facility will be operated for the life of the gas wells in the area. This is currently estimated to be 20 years or more. At the end of the economic life of wells in the area, the site will be reclaimed by removing all surface facilities, plugging the injection well, grading to restore original contours, replacing topsoil, and revegetating the reclaimed area as outlined in the Reclamation Plans included in this submittal. A copy of Ursa’s Blanket Surface Bond #2012-0126 is included. If deemed necessary by the County Commissioners, Ursa will provide financial assurance for the purpose of ensuring the proper reclamation and closure of the facility. The entire proposed area of disturbance will be reviewed and approved by the COGCC prior to construction and operation. COGCC and Colorado Parks and Wildlife inputs have been factored into engineering design and wildlife protections for the facility. Per the Garfield County Land Use and Development Code Section 4-203.B.3 a list and a map of real property, the owners of record and mailing address, within a 200-foot radius of the subject parcel and mineral owners were identified through records in the office of the Clerk and Recorder and/or Assessor’s office.

This review is being submitted to satisfy the Garfield County Regulatory Requirements outlined in section 4-203 (E) of the Garfield County Land Use and Development Code. The purpose of this drainage letter is to review the hydrologic impacts of the proposed developments. “Historic”, is defined for purposes of this letter as pre-gas pad development, and the “proposed”, as defined as post gas pad development. Methodology The peak runoff flows for the analysis were determined using the Rational Method. The Urban Drainage Flood Control District (UDFCD) Rational Method spreadsheets were utilized to calculate design flows. Design criteria established by Garfield County require that the peak discharge rate does not exceed the historic peak rate for the 2 year and the 25 year storm events. The County also requires that storm water detention facilities (if required) must demonstrate that there is safe passage of the 100 year event without causing property damage. Based on NOAA Atlas 14 point precipitation frequency estimates, the site 1-hour rainfall for the 2 year, 25 year and 100 year 24 hour precipitation events are calculated to be 0.489, 1.04 and 1.43 inches per hour respectively, see hydrologic tables in appendix A. Jan 22, 2015 Page 2 matrixdesigngroup.com The type of ground cover and soils affects the runoff volume from a site. The USDA NRCS Web Soil Survey was utilized to determine the soils data. The survey determined the primary majority soil type within the limits of the project is 56-Potts Loam with a hydrological group rating of “C” indicative of slow water infiltration. Reference attached soil map and hydrologic engineering data Runoff coefficient numbers were calculated in the Rational Method Spreadsheets and are determined based on the impervious area within each basin. The travel lengths and time of concentration were also calculated in the spreadsheets and based upon overland flow, shallow concentrated flow and channelized flow characteristics. Historic Conditions The existing topography of the “historic” site, before the existing gas pad was installed, drained in general from east to the northwest corner joining flows within a large gulch. The area of interest can be divided into two drainage basins, which are 66.92 acres and 26.07 acres in size, and begin further off to the east of the site. These are sparsely vegetated with some sage brush cover. Information on the historic property was calculated using USGS data and partial survey data. Historic storm water flows were calculated using an imperviousness of 2% and yielded a Q2/Q25 = 2.76/40.40 cfs for parcel H1 and Q2/Q25 = 1.14/16.71 cfs for parcel H2. Proposed Conditions The site will be altered by the addition of a 800 by 350 ft gravel pad and site grading. Water flow will now either go over the pad, which has minimal slope, or conveyed around the pad in drainage swales. The majority of the drainage basin areas will remain undisturbed, with 9.43 acres in basin H1 and 1.34 acres in basin H2 being altered for the pad. This does not constitute a majority of the area in question, and will not greatly affect rates of discharge. Affected water in area H2 will be diverted through a culvert under a proposed road leading to the southwest. Storm water flows were calculated using an imperviousness of 2% in historic areas and 5% in disturbed areas. This yielded a Q2/Q25 = 3.13/40.40 cfs for parcel H1 and Q2/Q25 = 1.14/16.71 cfs for parcel H2. Detention/Storm Water Quality/Erosion Control Due to the magnitude of the contributing basins, and low imperviousness of the proposed developments, flow from the two inspected basins will not be altered greatly by the addition of Jan 22, 2015 Page 3 the proposed pad, and thus there will be no required 25 year detention on the site. The larger impact of developments is with regards to water quality and protecting the surrounding environment. Matrix proposes 8' x 6' sediment traps, per UDFCD SC-8, at each ditch discharge point for water quality measures and possible secondary spill containment. Construction best management practices for the protection of water quality and flows should be followed, to conform with operating guidelines established by URSA for spill containment and incident isolation. Erosion control measures include temporary mulch and seeding area, installed with erosion control blankets , inlet protection at the culvert under the road , silt fences and sediment logs in drainage swales. Conclusion This storm drainage analysis reviewed historic and proposed conditions, calculated estimated storm water runoff consistent with the requirements of Garfield County and indicates that the design approach is feasible and meets standard engineering guidelines. Due to the low runoff of the historic and proposed conditions , no detention is required for the site. The storm water management will be conducted by other through final stab ilization , but appears based on the information presented, to be in general conformance to good practices typical of the oil & gas industry. The project is not located in the 100-year floodplain.

United States Department of Agriculture A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Rifle Area, Colorado, Parts of Garfield and Mesa Counties Watson Ranch B Pad Natural Resources Conservation Service January 14, 2015 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/ nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:// offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil- landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If Custom Soil Resource Report 10 intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

Storm Water Management Plan (SWMP) is written to comply with the Colorado Department of Public Health and Environment’s (CDPHE) General Permit No. COR- 030000 issued on May 31, 2007 and has been administratively continued effective of July 1, 2012, and related U.S. Environmental Protection Agency (USEPA) National Pollutant Discharge Elimination System (NPDES) storm water regulations. This larger common plan of development SWMP addresses construction activities associated with development of natural gas resources in the Battlement Mesa in Garfield County, Colorado. The Battlement Mesa SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. This SWMP will be updated in accordance with Parts I.D.5.c, d of the permit. This SWMP is in two parts: (1) the field-wide SWMP for Ursa activities within the Battlement Mesa project area; and (2) additional, dynamic, information (including inspection forms) for well pads, compressor stations, and roads. The field-wide SWMP includes a general area description, area boundary map, descriptions of Best Management Practices (BMPs), description of materials handling and spill prevention, inspection, maintenance procedures, and definition of final stabilization. Site-specific tables within this field-wide SWMP Appendices address individual ground-disturbing activities. The site-specific information found in Table 3 contains information such as facility location, construction limits, BMP locations and detailed current site conditions. Additional information on Ursa’s specifics of administrative operations is provided in the appendices. This SWMP will need to be updated/revised during the life of the project. Updates will include: 1. Revision of existing BMPs as needed to address erosion and sediment control. 2. Deletion of BMPs and reduction in monitoring frequency for individual facility locations where interim and long-term stabilization have been successfully established. 3. Regulation updates, Table and Appendix revisions. This SWMP will have a separate revision log sheet; this log sheet will have dates that the SWMP was modified as applicable, refer to Table 2. This SWMP is written to contain general storm water management practices, as well as site specific information related to specific construction activities occurring in the Battlement Mesa field area. Site specific information found in Table 1 includes phased BMP implementation, areas of disturbance, schedule of construction activities, final stabilization measures, current BMPs, and potential pollution sources. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the United States from any point source be regulated by NPDES permits. In November 1990, the USEPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 2 May 2013 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999, the USEPA published final Phase II NPDES regulations that established application requirements for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. Storm water construction permits are required for oil and gas activities that disturb 1 or more acres during the life of the project, or are part of a larger common plan of development. CDPHE considers a common plan of oil and gas development to mean development of several well pads and/or related infrastructure in a contiguous area either during the same time period or under a consistent plan for long-term development. 1.2 Project Description and Background Within the Battlement Mesa project area, Ursa Operating Company, LLC (Ursa) is charged with construction, operation, and maintenance of access roads, well pads, and gas gathering pipelines and facilities. Ursa is responsible for implementing storm water management as it pertains to their respective operations within the Battlement Mesa project area. This SWMP is developed, maintained, and implemented to suit the needs of each construction activity within the Battlement Mesa project area. The Battlement Mesa natural gas wells and associated infrastructure will be located within Township 7 South, Range 95 West, of the 6th P.M. Construction activities will include clearing/maintenance of drilling pads, clearing/maintenance of natural gas facilities (compressor stations), construction/maintenance of access roads, and the eventual construction of natural gas flow and gathering pipelines. The area of disturbance including the natural gas well pads, the access roads and gathering system pipeline will be greater than one acre. Currently there are actively producing wells and natural gas facilities within the Battlement Mesa project area. Refer to Table 1 for information regarding existing facilities, proposed facilities, and facilities under construction. New disturbances will occur as additional access roads and well pads are constructed and/or maintained. 1.3 Project Owner and Operator The Project owner/operator: Ursa Operating Company, LLC 1050 17th Street, Suite 2400 Denver, CO 80265 Contact for the project is: • Robert W. Bleil, Regulatory & Environmental Manager/ SWMP Administrator Main: 970.625.9922 E-mail: rbleil@ursaresources.com Ursa will be in charge of all aspects of this project. Contractor(s) will do the actual construction and grading, but all work will be supervised by Ursa or a representative(s), and all decisions will be made by Ursa, or a representative(s). 3 May 2013 2.0 CONSTRUCTION SITE LOCATION DESCRIPTION 2.1 Site Location The Battlement Mesa natural gas wells and associated infrastructure will be located within Township 7 South, Range 95 West, of the 6th P.M. Once the natural gas wells are completed and brought into production it will be necessary to construct flow lines, gathering system pipelines and tank batteries to handle liquid storage, and construct access roads to the individual well sites and pipelines access points. The Battlement Mesa natural gas wells will be constructed using conventional cut and fill earthmoving techniques. Typically, the working pad surface will have dimensions of approximately 350’ x 250’. There will be a 50’ buffer area around the pad surface to implement storm water BMPs. Specific pad dimensions may vary depending on the planned drill rig, number of wells to be drilled from each pad, and local conditions. After all well pads have been constructed and all production facilities have been installed, the well pad will be graded to reduce cut and fill slopes and to minimize the overall size of the pad. The well pad will be revegetated after grading activities have been completed. This “interim reclamation” phase will exist until 70% stabilization (including revegetation, compacted road surfaces, etc.) has been reached, after which “final stabilization” will be declared. “Final stabilization” will require the 70% stabilization and the removal of any temporary BMPs. The well pad will remain in the “final stabilization” phase of the long-term production configuration for as much as 30 years or more (typically, until the well’s production declines to sub-economic levels). After a well has been plugged and abandoned and surface facilities removed, the well pad will be graded to restore approximate pre-disturbance contours and will be revegetated. In areas that are disturbed by well pad construction, topsoil will be stripped and stockpiled near the site. Topsoil stockpiles will be seeded as soon as practicable to preserve the topsoil resource. Soil materials will be managed so that erosion and sediment transport are minimized. Site Maps Refer to Appendix A for maps showing locations of well pads, access roads, pipelines and their associated storm water BMPs. Maps will be generated for each applicable well pad showing construction site boundaries, ground disturbance areas, cut and fill areas, all storage areas, all structural and non-structural BMPs, and all potential pollution sources. 2.2 Schedule of Construction Activities Construction schedules will vary. Minor road maintenance will occur on an “as needed” basis. Refer to Table 1 for information regarding site specific construction and maintenance activities for well pads and access roads. Once an approved drilling permit application has been received from the Colorado Oil & Gas Conservation Commission (COGCC), clearing and grading activities will be performed at the well pad sites. The clearing and grading will be performed during 4 May 2013 daylight hours to prepare the site prior to drilling. Temporary storm water BMPs will be implemented prior to well pad construction. Once stabilization is achieved, defined as construction activities being complete and all disturbed areas have been either built on, paved, or a uniform vegetative cover established with a density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed a well pad may be removed from this SWMP. However, if petroleum hydrocarbons or other chemicals impact storm water as a result of industrial activities onsite, the impacted storm water will be addressed by following the Ursa spill prevention control and countermeasures (SPCC) plan. 2.3 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil/vegetative cover.

The ultimate receiving water is the Colorado River. Refer to Appendix A for the Site Maps and distances to live waters. 2.5 Native Vegetation Native vegetation consists of wheatgrass, needleandthread, Pinyon, Utah Juniper, Bitterbrush, Shadescale, Saltbush, Greasewood, Rabbitbrush, Yucca, Galleta grass, a variety of Astragalus and Sagebrush. Vegetative cover varies from 40% to 100% depending on site specificity. 7 May 2013 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with construction sites and natural gas development include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers; • Sanitary sewage associated with portable toilets; • Well completion fluids; • Drill cuttings and drilling fluids; • Produced water; and • Condensate. The most common source of pollution from construction activities is sediment, which can be carried away from the work site with storm water runoff, and ultimately impact the water quality of a receiving stream. Clearing, grading, and otherwise altering previously undisturbed land can increase the rate of soil erosion over pre-disturbance rates. Petroleum products can also be potential storm water pollutants. These products are used in construction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from lay-down areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. For site specific potential pollution sources, refer to Table 1. Maps of each well pad will be generated showing the locations of all potential pollution sources. No concrete washout activities are expected. Vehicle tracking pads may be required for well pad development within the Battlement Mesa. All BMPs implemented throughout the project are intended to mitigate for the release of sediment and all other potential pollution sources described above, and listed in Table 1. Ursa Operating Company spill prevention and response policies must be followed and include the following: • Notification procedures to be used in the event of a material release or accident. At a minimum, the production supervisor should be notified. Depending on the nature of the spill and the material involved, Ursa Environmental staff, the CDPHE, downstream water users, or other agencies may also need to be notified. The WQCD toll-free 24-hour environmental emergency spill reporting line is (877)518-5608. • Provisions for absorbents are to be made available for use in fuel areas. 8 May 2013 4.0 DESCRIPTION OF SOIL CONTROL MEASURES The objective of erosion sediment controls is to minimize the release of sediments and any other potential pollutants by storm water runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes erosion and sediment controls to be used during the ROW construction to minimize possible pollutant impacts to storm water runoff. Refer to Appendix D for implementation details of soil control measures. Refer to Appendix A for locations of soil control measures. 4.1 Structural Practices for Erosion and Sediment Control Structural practices implemented to provide erosion and sediment control can include temporary and permanent BMPs. Temporary structural BMPs include, but are not limited to, straw bale barriers/check dams, temporary water bars and straw fiber rolls/wattles. When applicable, temporary BMPs will be implemented during construction and interim reclamation phases. All temporary BMPs will be removed and disposed of upon final stabilization. Permanent structural BMPs include, but are not limited to; earthen berms, drainage dips, bar ditches, diversion ditches, sediment basins, culvert inlet/outlet protection, and rock check dams. 4.1.1 Straw Bale and Rock Check Dams Straw bale and rock check dams will be installed in areas of concentrated flow. The purpose of a check dam is to reduce the velocity of water enough to allow sediment to settle, while allowing the clean water to continue migrating. Some sediment will accumulate behind the check dam. Sediment should be removed from behind the check dams when it has accumulated to one-half of the original height of the dam and properly disposed of. Check dams will be inspected for erosion along the edges of the check dams and repaired as required immediately. 4.1.2 Straw Wattles/Straw Rolls Straw rolls/wattles are intended to capture and keep sediment on a disturbed slope. Straw rolls are useful to temporarily stabilize slopes by reducing soil creep and sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one (1) to two (2) years. The slope needs to be prepared before the rolls are placed. Small trenches are created across the slope on the horizontal contour. The trench should be deep enough to accommodate half the thickness of the roll. The trenches need to be 10 to 25 feet apart. The rolls need to be installed perpendicular to water movement, parallel to the slope contour. The rolls need to fit snugly against the soil. No gaps should be between the soil and roll. There should only be one (1) to two (2) inches of stake exposed above the roll. The stakes should be installed every four (4) feet. 4.1.3 Diversion Berm/Channel Diversion ditches can be a temporary or permanent structural BMP installed to direct runoff or run-on storm water away from construction activity. Ditches direct water into 9 May 2013 sediment basin or other BMP structure designed to capture sediment while allow water to move through. 4.1.4 Culvert Inlet/Outlet Protection Inlets and outlets of culverts will be protected to prevent sediment build up within the culvert, thus maintaining culvert functionality. Temporary protection during construction can be implemented by installing straw bales or straw wattles around the inlet/outlet. For permanent protection, inlets/outlets shall be protected via rock armoring. Sediment accumulated at the inlet/outlet shall be removed as needed to ensure that there will be no blockage of the culvert. 4.1.5 Sediment Basins Sediment basins are structural BMPs installed to trap sediment that has been transported from other BMPs including, but not limited to, berms, perimeter diversion ditches, bar ditches, and drainage dips. Size and shape of each sediment basin shall depend on the specific location and surrounding topography of each site. 4.1.6 Armored Rundowns Armored rundowns are structural BMPs installed to minimize the erosion potential of the underlying substrate. Installation of armored rundowns can include, but is not limited to, inlet and outlet protection associated with sediment basins and ditches (i.e., sediment, diversion). 4.1.7 Straw Bale Barriers A straw bale barrier is a series of entrenched straw bales that are used to intercept and direct sheet flows. The barrier reduces runoff velocity and filters sediment from storm water as it moves through the barrier. The barrier may also be used to protect against erosion. 4.1.8 Water Bars Water bars can be a temporary or permanent structural BMP installed to direct runoff or run-on storm water away from construction activity. Bars slow velocity of water, and direct water into a sediment basin, or other BMP structure designed to capture sediment while allowing water to move through. 4.1.9 Tracking Pads Tracking pads are structural BMPs installed to trap sediment onsite prior to the respective vehicle leaving the location. Size and shape of the respective tracking pad(s) shall depend on the specific locations and surrounding topography of each site. 10 May 2013 4.2 Non-Structural Practices for Erosion and Sediment Control Non-structural practices implemented for erosion and sediment control will consist of permanent BMPs that will be utilized during all project phases from construction to interim reclamation, and ultimately to final stabilization. Non-structural controls typically include, but are not limited to, vegetative buffers, mulching, seeding of disturbed areas, erosion control blankets, and surface roughening. 4.2.1 Vegetative Buffers Vegetative buffers are areas of existing vegetation stands that are utilized as a permanent BMP. Vegetative buffers are located on any or all edges of a project boundary. They provide a filtering effect by minimizing velocity of storm water runoff enough to allow sediment to settle out while allowing clean water to continue with its natural drainage route. 4.2.2 Seeding of Disturbed Areas Seeding of disturbed areas will be implemented as a measure taken to achieve final stabilization. Upon construction completion, all disturbed areas to undergo reclamation shall be seeded. As a disturbed area is seeded, it will remain in the interim reclamation phase until the site has reached a vegetative cover area of 70% of pre-disturbance conditions. At this point, the site will be at the final stabilization phase. The main objective of drill seeding is to place the seed in the soil at the depth most favorable for seed germination. Topography will determine if seed will be applied via a drill seeder or if there is a need for broadcasting. Hand broadcasting is commonly used in areas too small for large equipment or if the terrain is too steep for equipment to work safely. Broadcast seeding throws the seeds randomly on the soil surface. This allows for a more mosaic plant population, but must be applied at twice the drill seed rate for successful germination. Once seed has been broadcast, raking or chaining the area will ensure seed to soil contact. Refer to Appendix E for the Project seed mixes and associated application rates. 4.2.3 Mulching Mulching is a non-structural BMP implemented to aid in seed establishment. After a disturbed area has been seeded, certified weed free straw mulch will be applied. Where accessible, the mulch will be crimped into the ground to provide additional soil stabilization. 4.2.4 Surface Roughening Surface roughening is an erosion control practice often used in conjunction with grading. Surface roughening involves increasing the relief of a bare soil surface with horizontal grooves by either stair-stepping (running parallel to the contour of the land) or using construction equipment to track the surface. Slopes that are not fine graded and left in a roughened condition also reduces erosion. Soil roughening reduces runoff velocity, increases infiltration, reduces erosion, traps sediment, and prepares the soil for seeding and planting; giving the seed an opportunity to germinate and establish. Used as a temporary or permanent BMP, surface roughening may take many different forms including, but not limited to, ripping, pocking and tracking. 11 May 2013 5.0 PHASED BMP IMPLEMENTATION During the Battlement Mesa development, each project will consist of a construction phase, an interim reclamation phase, and a final stabilization phase. There will be some BMPs implemented that can be utilized for each phase, however there will be certain controls implemented specifically for each phase. 5.1 Construction The construction phase of the project will consist of clearing the vegetation on the pad location, cut and fill activities for each pad and access road, and general grading. Appropriate BMPs will be installed for this phase of the construction. The following outlines the necessary steps of the construction phase: Well Pad(s) and Facilities • Vegetation Clearing: Vegetation will be removed and place around edge of disturbed area on down gradient side of fill slope. This will provide a brush barrier BMP for construction; • Topsoil will be utilized for berms or diversions; • Straw bale barriers or other temporary BMPs will be installed prior to construction; and • Concrete and truck washout area will be established, if applicable, once construction begins. Pipeline(s) • Pipelines will be installed along the road Right of Way when possible; • Temporary BMPs will be installed prior to construction; and • Permanent BMPs will be installed as ROW is reclaimed. 5.2 Interim Reclamation Interim reclamation will be the phase of each project between construction and final stabilization. A project will enter into interim reclamation when construction is completed, disturbed areas have been seeded, and permanent BMPs have been installed. Temporary BMPs that were implemented during the construction phase may continue to be maintained during interim reclamation. Projects will remain in interim reclamation until disturbed areas have been reclaimed to 70% of pre-disturbance conditions or otherwise permanently stabilized (i.e. graveled). Refer to Table 1 for BMPs implemented during the interim reclamation phase of each site. Well Pad(s) and Facilities • Topsoil will be used as material for swales or berms around the pad location; • Topsoil stockpile will be seeded and mulched immediately; and • Permanent BMPs will be installed, as temporary BMPs are removed if no longer a viable BMP. 12 May 2013 Pipeline(s) • Topsoil placement: Topsoil will be moved and redistributed across the surface of the disturbed area; • Vegetative material replacement/removal: Based upon BLM or landowner requirements, stripped vegetation may be hauled off-site or redistributed along the disturbed area; • Seeding: When applicable the disturbed ROW will be seeded post construction. The seed mix will vary depending on location and surface ownership and will generally match the surrounding vegetation. Refer to Appendix E for seed mixes and their respective application rate(s); and • Mulching: When applicable, all disturbed areas to be reclaimed will be mulched post seeding. A certified weed free straw will be crimped into the ROW to keep an adequate moisture level in the seedbed. 5.3 Final Stabilization Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre-disturbance levels has been established, or when an equivalent permanent, physical erosion reduction method is in place. Areas which are not used for facilities, access roads, material storages yards, or other work areas will be stabilized with vegetation. Areas that are stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre-disturbance has been established. Other areas that may include facilities, access roads, material storage yards, and other work areas will be stabilized through the use of permanent, physical erosion reduction methods that include, but are not limited to: • Surface covering – covering of the soil surface with structures that inhibit contact of precipitation with the soil surface, which is generally considered to be placement of a structure (building or tank) over the soil surface. • Gravel surfacing – gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspections reveal that the gravel surface is no longer effectively covering the soil surface, or performing its desired function. • Surface contouring/ditching – road surfaces that will not be graveled shall be constructed in a manner to prevent excessive erosion. Roads will be sloped in way to encourage positive drainage into bar ditches, and ultimately into sediment 13 May 2013 control structures. A compact, earthen berm will be constructed at the uphill side of the road slope. 6.0 MATERIALS HANDLING AND SPILL PREVENTION 6.1 Waste Management and Disposal The various construction activities mentioned in this SWMP will generate various other waste materials during the course of construction. These wastes typically include, but are not limited to, the following: • Trees and shrubs from clearing operations; • Trash and debris from construction materials and workers; and • Sanitary sewage. Each of these wastes will be managed so as to not contribute to storm water pollution. Trees and shrubs will be piled along the toe of fill slopes to provide additional sediment control. Construction trash and debris will be collected in appropriate containers and hauled off-site for disposal in suitable landfills. Sanitary waste will be contained in portable toilets or other storage tanks with waste materials regularly pumped and transported off-site for proper disposal at approved facilities. 6.2 Fuels and Materials Management Petroleum Products Petroleum products which may be present at the construction site include: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in containers up to 55-gallons in volume, in secondary containment. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proper maintenance and safe storage practices will reduce the chance of petroleum products contaminating the site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed. The following guidelines for storing petroleum products will be applied: • All product containers will be clearly and properly labeled; • Drums will be kept off the ground within secondary containment and stored under cover when necessary; 14 May 2013 • Fuel tanks will be stored within areas containing secondary containment; • Lids of drummed materials will be securely fastened; • Emergency spill response procedures will be available on-site (Persons trained in handling spills will be on call at all times); • Spill cleanup and containment materials (absorbent, shovels, etc.) will be readily available. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can be disposed of in accordance with applicable regulations; • Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary. Construction personnel should be informed about proper storage and handling of materials during weekly subcontractor or safety meetings; • Provisions for absorbents are to be made available for use in fuel areas; and • Spill response will be immediate, contaminated soils will be contained and disposed of in accordance with applicable regulations. Notification procedures are to be used in the event of a material release or accident. At a minimum, the field supervisor should be notified. Depending on the nature of the spill and the material involved, Ursa staff, the CDPHE, downstream water users, or other agencies may also need to be notified. Notification Requirements: • Ursa Facility Manager • Project Environmental Coordinator/Regional Coordinator • State Agency in accordance with applicable regulations Hot Line Numbers: • WQCD toll-free 24-hour environmental emergency spill reporting line is (877)518-5608. • Colorado Department of Natural Resources oil and Gas conservation commission- oil spills 303-894-2100 • National Response Center 800-424-8802 A construction site spill report will include the following details of the incident: • The date and time of the incident; • A description of the material spilled; • Quantity spilled; • Circumstances that caused spill; • List of water bodies affected or potentially affected by spill; • Statement verifying whether an oil sheen is present; • Size of the affect area; • An estimate of depth; • Determination of possible migration of spill off Ursa property; • Statement of time of cleanup, methods being used, and personnel involved; and 15 May 2013 • Name of person to first observe spill, witnesses and their affiliations. Other Chemical Product Management Various additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and leaks. Storage areas will be regularly inspected, and any minor spills or leaks will be cleaned up immediately. Materials Management The construction supervisor will maintain a lay-down or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential contamination. 6.3 Construction Site Housekeeping Housekeeping will consist of neat and orderly storage of materials and containerized fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at appropriate off-site facilities. In the event that a spill occurs, prompt cleanup is required to minimize any commingling of waste materials with storm water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks. Any waste product from maintenance will be contained and transported off site for disposal or recycling. There will be no major equipment overhauls conducted on site. Equipment will be transported off site when major overhauls are necessary. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the road way, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, along with any contaminated soil. Upon collection, these waste materials will be disposed of properly. 16 May 2013 7.0 DEDICATED CONCRETE OR ASPHALT BATCH PLANTS Not applicable to anticipated projects within the Battlement Mesa project area. 17 May 2013 8.0 VEHICLE TRACKING CONTROLS Vehicle track pads will be installed at all locations where it is considered necessary. Track pads will be approximately 20 feet wide and 20 feet long. This will eliminate sediment transport onto public roadways. 18 May 2013 9.0 INSPECTION AND MAINTENANCE PROCEDURES To meet the requirements of the Permit, inspection and maintenance of erosion and sediment controls must occur during the project. Continued inspection and maintenance is required for specific structures after construction is completed. The inspection program will include the following: 1. A certified person familiar with the SWMP and control measures will conduct the inspections. 2. Inspections will cover the following items within the construction site: • Disturbed areas without stabilization; • All structural and non-structural BMPs (temporary and permanent); • Material storage areas; • Surface water diversions; • Down gradient areas; and, • New access roads; • Site vehicle entrance/exit locations. 3. Inspections will occur at least once every 14 calendar days (during construction) and after a significant precipitation event, or snow melt event that causes potential for erosion. Once all measures have been taken to reach interim reclamation, inspections shall occur at least once every 30 calendar days. 4. A log of inspections will be maintained. 5. Water quality will be visually assessed for all receiving streams and discharge areas during each inspection. 6. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 7. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 8. Following each inspection, the SWMP will be modified as necessary to include additional controls designed to correct identified problems. Necessary revisions to the SWMP will be made within 7 days of the inspection. 9. An inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, the date of the inspection, and observations relating to proper implementation will be prepared. Inspection reports will be retained for at least 3 years from the date that the site is finally stabilized. 10. Actions taken to modify any storm water control measure will be recorded and maintained with the SWMP. 11. If no deficiencies are found during the inspection, the report will contain certification that the site is in compliance with the SWMP. Maintenance Procedures Maintenance will include prompt repairs and/or adjustments to any erosion and sediment control structures that are deteriorating or found to be performing inadequately. BMP conditions and dates of BMP maintenance will be documented within the storm water inspection checklists. Repairs are to be made as soon as possible and prior to the next anticipated storm event. 19 May 2013 Inspection Forms Inspection forms shall be a part of this SWMP and will include information such as dates of maintenance/modifications of existing BMPs, installation of new BMPs, any site housekeeping requirements, and general comments. Refer to Appendix C for an example of the storm water inspection document. 20 May 2013 10.0 NON-STORMWATER DISCHARGES No allowable sources of non-storm water discharges are anticipated from the project. Some possible exceptions include, but are not limited to, fire prevention/suppression or dust control activities. Produced water will be collected and hauled off site to a proper storage facility and not discharged. 21 May 2013 11.0 CERTIFICATIONS 11.1 Owner/Applicant Certification I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

Vegetation WORK COMPLETION (BMP CONTRACTOR USE ONLY) Inspector Signature: Applicable Regulatory Agency: Construction Manager: SITE MAP RECOMMENDED ACTIONS Processing Equipment D1 Appendix D – BMP Installation Details Check Dams Description and Purpose Check dames are small, temporary dams constructed across a swale or channel. Check dams can be constructed using gravel, rock, sandbags, logs, straw bales, or reusable products and are used to slow the velocity of concentrated flow in a channel and reduce erosion. Check dams reduce the effective slope of the channel, thereby reducing the velocity of flowing water, allowing sediment to settle and reducing erosion. Reduced slopes reduce the velocity of storm water flow, thus reducing erosion of the swale or ditch and promoting sedimentation. The use of check dams for sedimentation will likely result in little net removal of sediment because of the small detention time and probable scour during longer storms. Using a series of check dams will generally increase their effectiveness. A sediment trap may be placed immediately upstream of the check dam to increase sediment removal efficiency. Construction Specifications • Dams should be installed with careful placement of the construction material. Dumping of the material into a channel is not appropriate and will reduce overall effectiveness. • Check dams can be constructed from a number of different materials. Most commonly, they are made of rock, straw bales, or sand bags. When using rock or stone, the material diameter should be 2 to 15 inches or sized appropriately to the site specific conditions. • The center of the dam should be at an elevation which is lower than the edges. This design creates a weir effect that helps to channel flows away from the banks and prevent further erosion. • Additional stability can be achieved by implanting the dam material into the sides and bottom of the channel. • Check dams may be used in a series and spaced as needed to reduce flow velocity and as site conditions allow. • When installing more than one check dam in a channel, outlet stabilization measures should be installed below the final dam in the series. Because this area D2 is likely to be vulnerable to further erosion, riprap, geotextile lining, or some other stabilization measure is recommended. Maintenance Considerations Inspection frequency shall be in accordance with the Storm Water Pollution Prevention Plan. During inspection, large debris, trash, and leaves should be removed. The center of the check dam should always be lower than its edges. If erosion or heavy flows cause the edges of a dam to fall to a height equal to or below the height of the center, repairs should be made immediately. Accumulated sediment should be removed from the upstream side of a check dam when the sediment has reached a height of approximately one-half the original height of the day (measured at the center). D3 Removal/Abandonment Check dams may or may not be removed depending on the material of construction and site specific conditions. Check dams shall only be removed after the contributing drainage area has been completely stabilized. D4 Straw Wattles/ Fiber Rolls Description and Purpose A wattle (also called a fiber roll) consists of straw, flax, or other similar materials bound into a tight tubular roll. When wattles are placed at the toe and on the face of slopes, they intercept runoff, reduce its flow velocity, release the runoff as sheet flow, and provide removal of sediment from the runoff. By interrupting the length of a slope, fiber rolls can also reduce erosion. Wattles should be either prefabricated rolls or rolled tubes of erosion control blanket. (If using an erosion control blanket roll the length of erosion control blanket into a tube of minimum 8 in. diameter and bind roll at each end and every 4 ft along length of roll with jute-type twine.) Minor deviations from the following construction specifications are acceptable as long as performance oriented specifications are maintained. The performance oriented specification for wattles is that sediment is not observed on the down gradient side of the wattle row. If sediment is observed on the down gradient side of the wattle, the wattle should be re-installed. Construction Specifications 1. Locate wattles on level contours where possible. However, wattles may also be used off-contour to direct runoff to an outlet sediment control BMP (i.e. a sediment trap) or used as a check dam within a diversion ditch. 2. Suggested spacing of wattles for use of permanent slopes is as follows: a. Slope inclination of 4:1 (H:V) of flatter: Fiber rolls should be placed at a maximum interval of 20 ft. b. Slope inclination between 4:1 and 2:1: Fiber rolls should be placed at a maximum interval of 15 ft. (A closer spacing is more effective). c. Slope inclination 2:1 or greater: Fiber rolls should be placed at a maximum interval of 10 ft. (A closer spacing is more effective). D5 3. Wattles may also be used on temporary slopes at a spacing determined in the field or as a single wattle placed at the toe of the slope of at the perimeter of a project. 4. Turn the ends of the wattles up slope to prevent runoff from going around the roll. When using wattles to direct runoff to another BMP, the ends of the wattles do not need to be turned up slope. 5. Stake wattles into a 2 to 4 in. deep trench with a width equal to the diameter of the wattle. If frozen conditions prevent trenching, wattles may be temporarily secured to the ground without trenching. However, when warm weather permits, wattles will be re-installed in a trench. 6. Drive stakes at the end of each wattle and the stakes should be installed every 4 feet. 7. If more than one wattle is place in a row, the rolls should be overlapped or tightly abutted. Maintenance Considerations • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Repair or replace split, torn, unraveling, flattened, saturated, or slumping rolls. • If the wattle is used as a sediment capture device, or as an erosion control device to maintain sheet flows, sediment that accumulates must be periodically removed in order to maintain wattle effectiveness. • Sediment should be removed when sediment accumulation reaches one-half the designated sediment storage depth, usually one-half the distance between the top of the wattle and the adjacent ground surface. D6 Removal/Abandonment Once a wattle is no longer necessary it should be removed. Collect and dispose of sediment accumulation, and fill and compact holes, trenches, depressions or any other ground disturbance to blend with adjacent ground. D7 D8 Diversion Berm/Channel Description and Purpose A diversion berm or channel is a structure that intercepts, diverts and conveys surface run-on, generally sheet flow, to prevent erosion. Earth dikes/drainage swales are not suitable as sediment trapping devices as the main purpose is to manage flow direction. These structures may however be modified when integrated with other soil stabilization and sediment controls, such as check dams, plastics, and blankets, to prevent scour and erosion in newly graded dikes, swales and ditches. Implementation General Earth dikes/drainage swales may be used to convey surface runoff down sloping land, intercept and divert runoff to avoid sheet flow over sloped surfaces, divert and direct runoff towards a stabilized watercourse or channel or intercept runoff from hardened surfaces such as well pads or roadways. Additionally, earth dikes/drainage swales may be used below steep grades where runoff begins to concentrate, along roadways and facility improvements subject to flood drainage. at the top of slopes to divert run-on from adjacent or undisturbed slopes and/or at bottom and mid-slope locations to intercept sheet flow and convey concentrated flows. Design and Layout • Install riprap, grouted riprap, or concrete apron at selected outlet. Riprap aprons are best suited for temporary use during construction. • Compact subgrade and/or berm. • Use stabilizing cover (i.e. seeding, hydroseeding or blankets) when necessary, as determined by slope and erosion potential of the soil. • Modification of this BMP type may be necessary due to site specific requirements. At these locations sediment basins, rock check dams, erosion control blankets and/or seeding types of BMPs will be integrated. Design, layout and implementation should maintain and follow each BMP type general installation specification. • Refer to the schematic detail at the end of this section. D9 Inspection and Maintenance • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Inspect ditches and berms for washouts. Replace lost riprap, damaged linings or soil stabilizers as needed. • Inspect channel embankments, linings and beds of ditches and berms for erosion and accumulation of debris and sediment. Remove debris and sediment once 75% of the capacity has been filled, and repair linings and embankments as needed. • Temporary conveyances shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. D10 Culvert Inlet/Outlet Protection Description and Purpose Culvert inlet/outlet protection typically consists of gravel riprap that act as energy dissipation features, thus allowing for the settling of sediments, while preventing piping or undercutting from occurring at the inlet or outlet. Riprap should consist of small to medium gravels that are layered to achieve uniform density. Implementation General Culverts may be installed on a site specific basis to provide a method of transport through confining features such as roadways and well pads. D11 Design and Layout • Install riprap, grouted riprap, or concrete apron at selected outlet. Riprap aprons are best suited for temporary use during construction. • Carefully place riprap to avoid damaging the filter fabric, if applicable. • For proper operation of apron: o Align apron with receiving stream and keep straight throughout its length. If a curve is needed to fit site conditions, place it in upper section of apron. o If size of apron riprap is large, protect underlying filter fabric with a gravel blanket. • Outlets on slopes steeper than 10% shall have additional protection. Inspection and Maintenance • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Repair or fill any unnecessary gaps or holes in the inlet/outlet of culverts. • Inspect for scour beneath the riprap and around the outlet. Repair damage to slopes or underlying filter fabric immediately. • Temporary devices shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. D12 Sediment Basin Description and Purpose A sediment basin provides adequate settling time, retention capacity and reduction of flow velocities minimizing erosion and allowing for settling of suspended sediment. A basin may be constructed by the construction of a barrier or dam across a natural drainage path, by excavating a basin or by a combination of both. Basins usually consist of a dam, blanketed or hydroseeded downgradient slopes/berms and a stabilized outlet (spillway). Implementation A sediment basin is a temporary containment area that allows sediment in collected storm water to settle out during infiltration or before the runoff is discharged through a stabilized spillway. Sediment basins are formed by excavating or constructing an earthen embankment across a waterway or low drainage area. Basins should be placed at the end of perimeter sediment ditches, diversion ditches, along bar ditches upgradient areas from which sediment-laden storm water directly enters a drainage or watercourse. The size of the structure will depend upon the location, size of drainage area, soil type, rainfall pattern and desired outflow releases. Design and Layout • Sediment basins should be constructed prior to the rainy season and commencement of construction activities in the area. • Sediment basins are not to be constructed in any live stream. • Sediment basin(s), as measured from the bottom of the basin to the principal outlet, should have at least a capacity equivalent to 100 cubic meters (3,532 cubic feet) of storage per hectare (2.47 acres) draining into the sediment basin. The length of the basin should be more than twice the width of the basin. The length is determined by measuring the distance between the inlet and the outlet. The depth must not be less than 0.9 m (3 ft) nor greater than 1.5 m (5 ft) for safety reasons and for maximum efficiency. • Multiple traps and/or additional volume may be required to accommodate site specific rainfall and soil conditions. • Basins with an impounding levee greater than 1.5 m (5 ft) tall, measured from the lowest point to the impounding area to the highest point of the levee, and basins D13 capable of impounding more than 1000 cubic meters (35,300 cubic feet), shall be individually designed and implemented with direct on-site oversight provided by appropriate and designated personnel. Additional safety requirements such as fencing may also be required. • Rock, blankets, hydromulch and/or vegetation shall be used to protect the basin inlet and slopes against erosion. • Embankments shall be constructed of a material and size (i.e. sorted, with fines) capable of attaining sufficient levels of compaction and conductivity to ensure the structural integrity of the structure and its desired retention capacity and capability. Generally compaction of the structure is by use of heavy machinery • Use rock or vegetation in addition to geotextile to protect the basin outlet(s) against erosion. Inspection and Maintenance • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Inspect sediment basin banks for embankment seepage and structural soundness. • Inspect inlet and outlet (rock spillway) areas for erosion, damage or obstructions and stabilize/maintenance as necessary. • Remove accumulated sediment when the volume has reached one-third the original trap volume. • Properly disposed of sediment and debris removed from the trap. D14 Riprap/ Armored Rundown Description and Purpose Lined channels are excavated channels or swales lined with grass, riprap, or other protective material. They are intended to carry concentrated runoff to a stable outlet without causing erosion or flooding. In some cases they are designed to allow runoff to infiltrate into the surrounding soil (Figure 6). Design and Installation Grass-lined channels may have V-shaped, parabolic, or trapezoidal cross-sections. Side slopes should not exceed 3:1 to facilitate the establishment, maintenance, and mowing of vegetation. A dense cover of hardy, erosion-resistant grass should be established as soon as possible following grading. This may necessitate the use of straw mulch and the installation of protective netting until the grass becomes established (see BMP 2.2, Mulching and Matting). If the intent is to create opportunities for runoff to infiltrate into the soil, the channel gradient should be kept near zero, the channel bottom must be well above the seasonal D15 water table, and the underlying soils should be relatively permeable (generally, with an infiltration rate greater than 2 cm per hour). Riprap-lined channels may be installed on somewhat steeper slopes than grass-lined channels. They require a foundation of filter fabric or gravel under the riprap. Generally, side slopes should not exceed 2:1, and riprap thickness should be 1.5 times the maximum stone diameter. Riprap should form a dense, uniform, well-graded mass. Applicability, Limitations, and Common Problems A limitation of lined channels is that they tend to take up substantial land area on a site. Where land is expensive they may not be a cost-effective solution. Grass-lined channels typically are used in residential developments, along highway medians, or as an alternative to curb and gutter systems. Grass-lined channels should be used to convey runoff only where slopes are 5% or less. They require periodic mowing, occasional spot-seeding, and weed control to ensure adequate grass cover. Common problems in grass-lined channels include erosion of the channel before vegetation is fully established and gullying or head cutting in the channel if the grade is too steep. Trees and brush tend to invade grass-lined channels, causing maintenance problems. Riprap lined channels can be designed to safely convey greater runoff volumes on some- what steeper slopes. However, they should generally be avoided on slopes exceeding 10%. Common problems include stone displacement or erosion of the foundation, or channel overflow and erosion because the channel is not large enough. Channels established on slopes greater than 10% will usually require protection with rock gabions, concrete, or other highly stable and protective surface. Riprap rundown information obtained from: http://www.cep.unep.org/pubs/Techreports/tr32en/content.html D16 Straw Bale Barrier Description and Purpose A straw bale barrier is a series of straw bales placed on a level contour to intercept sheet flows. The use of a straw bale barrier ponds sheet- flow runoff, allowing sediment to settle out. Implementation A straw bale barrier consists of a row of straw bales placed on a level contour. When appropriately placed, a straw bale barrier intercepts and slows sheet flow runoff, causing temporary ponding. The temporary ponding provides quiescent conditions allowing sediment to settle. Straw bale barriers also interrupt the slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets, which erode rills, and ultimately gullies, into disturbed, sloped soils. Straw bale barriers have not been as effective as expected due to improper use and installation. These barriers have been placed in streams and drainage ways where runoff volumes and velocities have caused the barriers to wash out. In addition, failure to stake and entrench the straw bale has allowed undercutting and end flow. Use of straw bale barriers in accordance with this BMP should produce acceptable results. Bales should be placed in a single row on a level contour with ends tightly abutting one another. All bales should be installed on their sides so that twine or binding runs around side of bale rather than on the top and bottom. Bales should be trenched in and staked. See illustration below. D17 Materials • Straw Bale Size: Each straw bale should be a minimum of 14 in. wide, 18 in. in height, 36 in. in length and should have a minimum mass of 50 lbs. The straw bale should be composed entirely of vegetative matter, except for the binding material. • Bale Bindings: Bales should be bound by steel wire, nylon or polypropylene string placed horizontally. Jute and cotton binding should not be used. Baling wire should be a minimum diameter of 14-gauge. Nylon or polypropylene string should be approximately 12-gauge in diameter with a breaking strength of 80 lbs force. • Stakes: Wood stakes should be commercial quality lumber of the size and shape shown on the plans. Each stake should be free from decay, splits or cracks longer than the thickness of the stake, or other defects that would weaken the stakes and cause the stakes to be structurally unsuitable. Steel bar reinforcement should be equal to a #4 designation or greater. End protection should be provided for any exposed bar reinforcement. Inspection and Maintenance • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Inspect straw bale barriers for sediment accumulations and remove sediment when depth reaches one-third the barrier height. • Replace or repair damage bales and washouts as needed • Remove straw bales when no longer needed. Remove sediment accumulation, and clean, re-grade, and stabilized the area. D18 D19 D20 Water Bar Description and Purpose A water bar is made of earthen fill, mound-trench built into a road, pipeline right-of-way (ROW) or well pad. The purpose is to divert water and dissipate energy by reducing flow velocity by redirecting inertia direction. Implementation Water bars are to be implemented at a 15 to 30 degree downslope position relative to the relief and layout of the roadway, ROW or well pad. Water bars are to be constructed using a bulldozer or road grater. The water bar should be built such that the uphill end of the bar ties into any adjacent bank, cut wall or preserved existing vegetation to receive ditch flow. An energy absorber on the downslope outfall, such as riprap, brush, native vegetative filter and the like, will serve to slow and dissipate the water's energy. When installed in series, the number used is dependent on the slope of the site/surrounding area and should generally proceed as follows: Grade (Degrees) Spacing (feet) between Water Bars 0-5 None Required 5-15 300 15-30 200 30 100 Water bars should be armored under circumstances of steep grades. The BMP should be also be stabilized with seeding/mulching with a mixture determined/agreed upon by an appropriate party. Water bars implemented at a pad entrance are intended to contain water on the pad. At these locations the water bar should be built such that both end tie into the pad perimeter berm. This provides 100% containment and control of the storm water collected on the pad from precipitation. Inspection and Maintenance • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Inspect sediment basins for sediment load and erosion around over flow. Inspect check dams for sediment load, and rilling from water tracking around outer edge of check dam. D21 Vehicle Tracking Pad Description: A rock construction entrance pad may be necessary at construction access locations to reduce the amount of mud transported onto paved roads by vehicles or surface runoff. Rock construction entrance pads provide an area where mud can be removed by vehicle tires traveling over the gravel pad before entering public roads. A construction entrance is a stabilized pad of aggregate over a geotextile base and is used to reduce the amount of mud tracked off-site with construction traffic. A temporary construction entrance is a stone pad located where vehicles leave a construction site. The purpose of the stone pad is to provide an area where mud can be removed from tires before a vehicle leaves the site. The stone pad consists of clean rock designed in such a way that vehicle tires will sink in slightly. This helps remove mud from the tires as the vehicle passes over the pad. If a wash rack is used, it provides an area where vehicle tires can be washed. Effectiveness: The effectiveness of temporary rock construction entrances for trapping sediment depends upon the length, depth of rock, frequency of use and maintenance, as well as the type of structure used. A newly installed rock construction entrance meeting the recommendations included here will be relatively effective for removing mud from tires before construction vehicles leave the site. However, once the rock voids become clogged with mud, the practice will not serve its intended D22 purpose until the rock is replaced. Washing vehicle tires with pressurized water over a wash rack will increase the effectiveness of the tracking pad for removing mud. Advantages: • Cost-effective • Highly effective for erosion and sediment control Limitations: • Muddy sites will require extensive maintenance of the vehicle tracking pad to ensure effective sediment removal. • Gravel can become quickly saturated with mud in certain soils and moisture conditions Design: The aggregate is recommended to be 1 to 3 inch washed rock. The aggregate layer should be 6 inches thick and extend the full width of the ingress and egress areas. The rock pad should be at least 50 feet long. A geotechnical fabric may be used under the aggregate to minimize the migration of stone into the underlying soil by heavy vehicle loads. If the majority of mud is not removed by vehicles traveling over the rock pad, the tires of the vehicle should be washed before entering a paved road. Wash water should be directed to a settling area to remove sediments. A wash rack installed on the rock pad may make washing more convenient and effective in removing sediment. Specifications: • The rock used for gravel pads should be a minimum 1 to 3 inch size, coarse aggregate • Aggregate should be placed in a layer at least 6 inches thick. Generally, the larger the aggregate, the better • Rock entrance should be at least 50 ft. long: however, longer entrances may be required to adequately clean tires. • Geotextile fabric may be needed under the rock to prevent migration of mud from the underlying soil into the stone. • If tires are cleaned with water, the wash water should be directed to a suitable settling area. • A wash rack installed on the rock pad may make washing more convenient and effective. The wash rack would consist of a heavy grating over a lowered area. The grating may be a prefabricated rack, such as a cattle guard, or it may be constructed o site of structural steel. In any case, the wash rack must be strong enough to support the vehicles that will cross it. • Culvert-A pipe or culvert shall be constructed under the entrance if needed to prevent surface water flowing across the entrance from being directed out on to paved surfaces. • Water Bar-a water bar shall be constructed as part of the construction entrance if needed to prevent surface runoff from flowing the length f the construction entrance and out onto paved surfaces D23 Maintenance: • In addition to the vehicle tracking pad, it is recommended that a street sweeper and scraper be kept on site during construction operations and the street areas adjacent to the tracking pad should be cleaned daily at the end of each construction day. • New rock should be added to the tracking pad whenever the existing rock becomes buried. • If conditions on the site are such that the majority of the mud is not removed by the vehicles traveling over the gravel, then the tires of the vehicles should be washed before entering a public road. • Wash water should be carried way from the entrance to a settling area to remove sediment; a wash rack may also be used to make washing more convenient and effective. • The rock entrance pad needs maintenance to prevent racking of mud onto paved roads. This may require periodic top-dressing with additional rock or removal and reinstallation of the pad. Areas used for sediment trapping may also need to be cleaned out. • Top dressing of additional stone shall be applied as conditions demand. Mud spilled, dropped, washed or tracked onto public roads, or any surface where runoff is not checked by sediment controls, shall be removed immediately. • The rock pad needs occasional maintenance to prevent the tracking of mud onto paved roads. This may require periodic topdressing with addition rock or removal and reinstallation of the pad. D24 Vegetative Buffers Description Vegetated buffers area areas of either natural or established vegetation (i.e. agricultural fields or otherwise re-vegetated areas) that are maintained to protect the water quality of neighboring areas. Buffer zones reduce the velocity of storm water runoff, provide an area for the runoff to permeate the soil, contribute to the ground water recharge, and act as filters to catch sediment. The reduction in velocity also helps to prevent soil erosion. Construction Specifications 1. Buffer widths should be determined after careful consideration of slope, vegetation, soils, depth to impermeable layers, runoff sediment characteristics, type and quantity of storm water pollutants, and annual rainfall. Buffer widths should increase as slope increases. 2. Mixed zones of vegetation are ideal, if available. 3. Direct sediment-laden water onto naturally vegetated ground. 4. Do not place any equipment, construction debris, or extra soil in the buffer area. Maintenance Considerations In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. Inspection of buffer areas is most important during ground disturbance activities. Inspections should focus on encroachment, gully erosion, density of vegetation, evidence of concentrated flows through the areas, and any damage from foot or vehicular traffic. If there is more than six inches of sediment in one place, it should be removed. D25 Drill Seeding/Hand BroadcastSeeding Description and Purpose Areas of disturbance are inevitable and are the premise for storm water management. To ensure the integrity of our water and vegetative communities as well as the security of our appreciable aesthetic surroundings re-vegetating disturbed areas is essential to this desire. There are a variety of methods that can be used to achieve the temporary and permanent vegetative cover required. These seeding methods are to include: • 1) Drill/Disc; • 2) Broadcast; and • 3) Hand (where applicable due to terrain and accessible distance). 1) Drill Seeding: This method consist of implementing the seed into the soil at a specific depth. Drill seeding utilizes a drill or cultipack seeder to inject the seeds beneath the soil surface. Seed depth is set based upon the seed type. Once the depth of the drill is determined the seed is then inserted and covered. This method provides optimization of seed placement to maximum seed contact with soil water. 2) Broadcast Seeding: This method of seeding scatters the seed at random on top of the soil surface rather than placing seed within the soil. Broadcast Seeding provides more of a native plant community than drill-seeded due to the randomly dispersal of seed. Seeing rates are doubled when using this method. 3) Hand Broadcast: This method of seeding scatters the seed at random on top of the soil surface by hand. Hand Broadcasting is used in areas of small disturbances and or locations which are unattainable by other methods. The seed can be implemented by scattering by hand or using a hand held broadcaster. Seeding rates are doubled when using this method. D26 Implementation Typical seeding practices will be as follows: • The permanent seed mix, rate, application method, and supplemental materials will be determined by appropriated personnel or the BLM/Landowner as appropriate for the land ownership. Generally, seeding will occur by broadcasting (hand and/or mechanical), or drilling (where applicable with inclusion of a tackifier). Design and Layout Application rates and procedures typically used are included as Figure 1 in this section. Additional seeding and mulching details are as follows: General Standards and Specifications • Prior to application, roughen embankment and fill areas by rolling with a crimping or punching type roller or by track walking. Track walking shall only be used where other methods are impractical. Inspection and Maintenance • Inspections will be on a 14 day cycle during construction and moved to a 30 day cycle once the site has moved into interm reclamation. • Areas should be identified where seed may have been damaged or removed. Such areas should be repaired, reseeded, and re-mulched. • Vegetation is considered complete when density of at least 70 percent of pre- disturbance levels has been reached. Inspect before expected rain storms and repair any damaged ground cover and re-areas of bare soil. • Inspections should be continued until vegetation is firmly established D27 Mulching Description Mulching is a temporary erosion control practice in which materials such as grass, hay, wood chips, wood fibers, straw, or gravel are placed on exposed or recently planted soil surfaces. Mulching stabilizes soils by minimizing rainfall impact and reducing storm water runoff velocity. When used in combination with seeding or planting, mulching can aid plant growth by holding seeds, fertilizers, and topsoil in place, preventing birds from eating seeds, retaining moisture, and insulating plant roots against extreme temperatures. Mulch mattings are materials such as jute or other wood fibers that are formed into sheets and are more stable that loose mulch. Jute and other wood fibers, plastic, paper, or cotton can be used individually or combined into mats to hold mulch to the ground. Netting can be used to stabilize soils while plants are growing, although netting does not retain moisture or insulate against extreme temperatures. Mulch binders consist of asphalt or synthetic materials that are sometimes used instead of netting to bind loose mulches. Construction Specifications 1. Site Preparation a. Prior to mulching, install the necessary temporary or permanent erosion control practices and drainage systems within or adjacent to the area to be mulched. b. Slope, grade and smooth the site to fit needs of the selected mulch products. c. Remove all undesirable stones and other debris to meet the needs of the anticipated land use and maintenance required. 2. Mulching & Anchoring a. Select the appropriate mulch and application rate that will best meet the need and availability of material. When possible, organic mulches should be used for erosion control and plant material established. All mulch should be certified weed free. b. Apply mulch after soil amendments and planting is accomplished or simultaneously if hydro seeding is used. c. Loose straw may be anchored using a crimper or tracked equipment. Mulch material should be “tucked” into soil surface about 3”. D28 Maintenance Considerations Mulched areas should be inspected in accordance with the Storm Water Pollution Prevention Plan is identify areas where mulch has loosened or been removed, especially after rainstorms. Such areas should be reseeded (if necessary) and the mulch cover replaced immediately. Mulch binders should be applied at rates recommended by the manufacturer. If washout, breakage, or erosion occurs, surfaces should be repaired, reseeded, and mulched, and new netting should be installed. Inspections should be continued until vegetation is firmly established. Removal/Abandonment Anchor netting and any other artificial mulch material should be removed when protection is no longer needed and disposed of in a landfill. D35 Surface Roughening Description and Purpose Surface roughening includes a variety of methods to create ridges, furrows, pocking or terraces in the soil surface. The ridges, furrows, pocking or terraces run perpendicular to the slope and the natural direction of runoff, slowing the runoff. Surface roughening helps to establish vegetative cover, prevent erosion, allow for infiltration, and trap sediment by reducing runoff velocity. Surface roughening can be used as a temporary or permanent BMP. Implementation Conditions of Practice All slopes steeper than 4H:1V and greater than 5 vertical feet, as well as any bare soil requiring some level of erosion prevention. Design Criteria/Specifications There are different methods for roughening the soil surface, and the selection of an appropriate method depends on the type of slope and the desired temporary or permanent slope vegetative treatment. The major consideration when using this BMP is to develop grooves or furrows that lie perpendicular to (across) the slope. The following criteria are for disturbed areas where existing vegetation has been removed: • All vegetation sites require some surface roughening: stair step, grooving, furrowing, pocking or tracking. • Areas that will be mowed (slopes less than 3:1) may have small furrows parallel to the slope contours (across the slope) left by discing, harrowing, raking, or other grooving methods from seed planting machinery operated on the contour. • Areas with vegetation that will not be mowed may be stair-step graded, grooved, pocked, or left rough after filling. • Slopes steeper than 2:1 shall be stair-stepped with benches (see Figure 4.5-A) or pocked. Stair-step grading or pocking are also appropriate for soils containing large amounts of rock. Each step or pock catches material that sloughs from above and provides a level site to convey or detain drainage or establish vegetation. Stairs shall be wide enough to work with standard earth-moving or maintenance equipment (12 feet minimum with no more than 15% slope). Heights shall be slope specific, but shall not exceed 3 feet without appropriate soils analysis or retaining structure support. • Excessive compaction of soils shall be avoided during grubbing. D36 • Tracking can compact soils, reducing infiltration. Tracking with a bulldozer is the least preferred method of roughening; however it is better than not roughening at all. Tracking shall be done up and down the slope to leave track tread indentations across the slope. • Roughened soil surfaces shall be seeded and mulched as quickly as possible. Inspection and Maintenance Specifications • In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. • Roughened areas without other cover shall be inspected after every rainstorm. If grooves, pocks, or stair-steps fill in, leaving less than one-third of the original groove or stair depth, the sediment shall be removed and the site re-roughened if necessary. D37 Sources: 1.

Ursa began operating in the Rifle/Silt area on April 1, 2013. The resources include Battlement Mesa field, North Gravel Trend field, Gravel Trend field, and Castle Springs field. The Roan resources are included in the North Gravel Trend field and the Wolf Creek resource is included in the Castle Springs field. Fields cover most of Township 7 South Ranges 91 and 95 West, Township 8 South Range 90 West, Township 5 South Ranges 91-93 West, and Township 6 South Ranges 90-93 West. This Plan will cover re-contouring, reseeding, noxious weed treatment, storm water mitigation and monitoring of the well pads, Rights of Way (ROWs), and other infrastructures required for natural gas operation. This plan is twofold: interim reclamation of a site once a site has been constructed and final reclamation of the site when the pad/ROW is no longer in operation and has been plugged and abandoned (P & A). The reclamation of disturbed land is a critical component when creating a system where ecological functions and values are restored once the ground disturbance activities have ceased. Rehabilitation of the disturbed area assists the natural ecological processes to move towards a self-promoting condition. Once a self-supporting environment has been established, the natural processes of the location can take over and continue the rehabilitation processes with minimal intervention from outside parties. The costs associated with the rehabilitation process will be minimized to the operator if proper treatments are applied initially to ensure the best environment possible for rehabilitation treatments to succeed. Bonding is required for oil and gas lease operations (43 CFR 3104, 36 CFR 228 E). The bond will cover the activities the operator performs including, but not limited to: plugging leasehold wells, surface reclamation, and cleanup of abandoned operations. The Colorado Oil and Gas Conservation Commission (COGCC) 1000 Series Reclamation Regulations declare that “all disturbed areas affected by drilling or subsequent operations, except areas reasonably needed for production operations or for subsequent drilling operations to be commenced within 12 months, shall be reclaimed as early and as nearly practical to their original conditions. This plan is designed to provide guidance concerning reclamation activities for Ursa land managers once the site of concern is no longer utilized for operations. The area to be reclaimed shall be kept as weed free as practicable of all undesirable noxious weed species. Weed control measures shall be conducted in compliance with the Colorado Noxious Weed Act (C.R.S. 35-5.5-101.et.seq). Storm water mitigation will be in compliance with the Colorado Department of Health and Environment (CDPHE) Water Quality Division General Permit Series COR-030000 and COGCC 1002.f regulations. 2 Procedures identified in this plan apply only to all Ursa Fields. All COGCC, CDPHE and Bureau of Land Management (BLM) procedures (site specific Conditions Of Approval or COAs) will be followed. Personnel working on this project should be familiar with the reclamation plan and its contents prior to preliminary construction activities. 3 2.0 Site Characteristics There are several communities located near the resource areas. Parachute, Battlement Mesa, and Rulison, are located in or near the Battlement Mesa field, (Township 7 South Range 95 West). Rifle, Silt, and New Castle, are located along the boundaries of the North Gravel Trend and Gravel Trend fields. Glenwood Springs is located approximately 27 miles to the east (Township 6 South Range 89 West). The resources range in elevation from 5,000- 9,500 feet and receive between 10-18 inches of precipitation per year. The frost free period ranges from 75 to 125 days, creating a growing season of approximately two and a half to four months. Each location has a site specific plan with details of soils, seed mix, and phase. Refer to Appendix C. COAs will be included in Appendix C for all sites located on federal lands. 4 3.0 Reclamation This plan covers: interim reclamation of a site once the site has been constructed and is in production, and final reclamation of the site when the location is no longer in operation and the well(s) have been plugged and abandoned (P & A). Interim reclamation and final reclamation will be in compliance with CDPHE and COGCC regulations. Construction and reclamation activities will be in accordance with the individual county noxious weed management plan (please refer to the Ursa Noxious Weed Plan). Dust suppression measures are required under the county grading permits and Federal land, and will be implemented as applicable. Each stage will be applied to the reclamation of the locations undergoing reclamation. Interim reclamation will be completed as stated in the Field Wide Storm Water Management Plan(s). All equipment used on reclamation projects will be cleaned and inspected prior to entering location to ensure noxious weed seeds are not being transported onto the site. 3.1 Stage One (Removal and Disposal) During reclamation of any site, once the pad/ROW/access road has been constructed, all wooden stakes used to secure wattles and straw bales, and other waste associated with construction of the site will be disposed of properly. This includes any trash left behind on location such as pipe fittings, used lumber or miscellaneous items that have been discarded. Petroleum products if on site should be contained in secondary containment. Interim Reclamation: • Pads – The initial footprint of the pad will be reduced, leaving enough room for everyday operations to occur on site in a safe manner and will be in compliance with COGCC 1003. All temporary storm water controls will be removed and permanent BMPs will be installed. Disturbed areas will be drill or broadcast seeded as applicable to the topography of the site. Seeding rate and mix will be determined by land owner. Certified weed free straw will be utilized at 2 tons per acre and crimped into place. • Pipelines – Pipelines will be seeded with the site specific seed mix per land owner requests. As applicable, certified weed free straw will be used as mulch at 2 tons per acre, and will be crimped into place. ROW will be monitored and permanent storm water best management practices (BMPs) will be installed to control erosion and sedimentation. • Roads – The access roads to a site will be properly graveled and stabilized. The cut and fill slopes of the access roads will be seeded and mulched as applicable to the individual site. Final Reclamation: • Pads – Pads in final reclamation will be plugged and abandoned (P & A), all temporary BMPs will be removed and replaced with permanent BMPs if necessary, and the surface area will be recontoured and seeded. Drill or broadcast 5 seeding methods will be used at the appropriate rate and depth. Surface roughening will be implemented to retain water and eliminate rilling. • Pipelines – Pipelines will be considered finally stabilized upon reaching 70% pre- disturbance vegetative cover, per the CDPHE general permit COR030000. • Roads – All access roads in final reclamation will be graveled and considered stable, with the sides of the roads are vegetated or stabilized. Closure of a road will consist of recontouring to existing topography, seeding, mulching and in some cases transplanting (using the trackhoe bucket) sagebrush and small trees on the edge of the road. During final reclamation of the site, when the pad is no longer in operation, all manmade structures will be removed from the site by means of backhoe, bulldozer, skidsteer or other appropriate heavy machinery. Structures may include, but are not limited to: compressor engines, generators, steel structures, cement foundations and other equipment used for the extraction of natural gas. Petroleum waste products if on site should be contained in secondary containment and disposed of properly. Gravel, road base and large cobbles installed on site for surface stabilization controls will be removed. Disposal and/or reuse method of gravel will be left to the discretion of the operator. 3.2 Stage Two (Substrate Preparation) In both phases of reclamation, the condition of the soil is very important for the establishment of a healthy self-sustaining environment. Locations where the soil has noticeable spills will have the contaminated soil removed or remediated, and disposed of in accordance with County and COGCC waste management regulations (refer to Ursa waste management plan). In the phase of final reclamation when active operations have ceased the substrate void of chemical presence, and gravel that was applied to the location during operations removed, reclamation efforts will take place. To alleviate soil compaction, the substrate will be cross ripped to a depth of 18 inches. Cross ripping will take place when the soil moisture is below 35 percent of field capacity. The cross ripping is specified by the COGCC under the 1000 Series Rules. The substrate shall be contoured to emulate the surrounding lands topography. Pre-disturbance photographs and visual extrapolations are to be used to create this contour. The soil used to contour the landscape will be applied in accordance to the order it was removed (i.e. first off, last on). This practice will ensure that the soil is applied to the appropriate horizon from which it was taken initially. Salvaged topsoil will be distributed across the entire disturbed area at a depth of six (6) to twelve (12) inches depending upon the landowner use agreement if possible. Should there be a shortage of topsoil available on site, the contractor will be responsible for replacement of lost or degraded topsoil with topsoil imported from an approved and certified weed-free source. 6 3.3 Stage Three (Planting/Timing) In both phases of reclamation, seedbed preparation will consist of scarifying, tilling or harrowing seedbed to a depth of three (3) to four (4) inches post ripping. This will occur just prior to seeding. Drill seeding will be performed at a depth of 0.5 inches, seed will be covered with soil and lightly compacted to ensure good seed to soil contact. Seed will be applied using a rangeland seed drill with a seed release and agitation mechanism sufficient to allow seeds of various size and density to be planted at the proper seeding depth. The seed mix for each reclamation project will be an approved Seed Mix (Appendix B). Certified weed free straw will be applied at a rate 2,000 lbs/acre and crimpled in place following drill seeding. Ideally planting will occur in the fall, before the first snow of the season. Early October is optimal. If possible, planting should occur in conjunction with a predicted precipitation event. By positioning the seed below the snow fall or rain, the seed will receive good contact with the soil and utilize the benefits of the precipitation. Spring planting can be conducted after the frost line is gone from the soil. During both phases of final reclamation, the seed mix associated with this site will be used. 7 4.0 Storm Water Mitigation 4.1 Best Management Practices (BMPs) To avoid erosion of topsoil and seed transport from storm events, Best Management Practices (BMPs) will be installed where applicable on the perimeter of any location being reclaimed. Given the location of the site, surface roughening and pocking will reduce storm water impact and capture and retain precipitation. This will aid in the germination of the seed and increase seedling survival. 4.2 Reclamation Monitoring Monitoring of the vegetative progress is vital to ensure that proper procedures were implemented on the location. Monitoring will allow for early response to potential problems encountered during the reclamation process. Identifying challenges to the reclamation goals at an early stage will allow for adequate time to formulate a response to the situation. By identifying potential complications early in the process, the future costs associated with rehabilitation will be minimized for the operator. If the treatments do not show the desired outcome, additional actions will be taken to reach reclamation goals. After the source of the problem is identified, careful attention will be paid to the timing of the supplemental treatment. If treatments such as seeding are not carried out at the proper time, the treatment will not be effective and to the operator will be increased rehabilitation costs. Monitoring activities will examine several parameters including: the condition of implemented BMPs, growth state and success rate of areas seeded, presence and location of noxious weeds, and possible sources of failure for reclamation processes. Photo documentation is required for all the above parameters for high-quality progress tracking. After the initial reclamation amendments are applied, and CDPHE requirements of 70 percent pre-disturbance levels have been met as well as COGCC requirements of 80 percent vegetative cover, a tri-annual monitoring scheme will be implemented. Monitoring activities will occur in the spring, summer and fall. Qualified individuals will carry out visual surveys and transects on site. Monitoring will occur until COGCC requirements of 80% desired vegetation has been reached. 8 5.0 References Colorado Oil and Gas Conservation Commission (COGCC). 2008.

Site Specific Interim Reclamation Plan Field Name: Battlement Mesa Phase: Interim Reclamation Project Name (Site): Watson Ranch B Well Pad Latitude: 39.4333 Longitude: -108.0233 Twp, Sec, Range: T-7-S, R-95-W Section 17 BMPS on Site: TBD Estimate of Total Area of Site: ~10.8 Estimate of Interim Acres: TBD Soil Types: Potts Ildefonso complex (12-25%), Potts loam (6-12%) Permeability: Moderate Soil Erosion Potential: Moderate Existing Vegetation Description: Wheatgrass, Needle and Thread, Sagebrush Interim Reclamation Date: TBD Seed Mix for Interim Reclamation: Ursa Dryland Pasture mix Date Seeded: TBD Reclamation Stages: This site specific Interim Reclamation Plan follows the Ursa Field Wide Reclamation Plan. This plan provides site specific details for the Watson Ranch B pad. The initial footprint of the pad will be reduced, leaving enough room for everyday operations to occur on site in a safe manner and will be in compliance with the COGCC 1003 Series. For general information please refer to the Ursa Field Wide Plan. Stage 1: All trash and debris will be removed from site, this includes any trash left behind on location such as pipe fittings, used lumber, degraded Best Management Practices (BMPs) such as Erosion Control Blankets (ECBs) on berm along site boundary or miscellaneous items that have been discarded. All trash will be removed and dispose of properly. Stage 2: Existing gravel on location will be moved to the inside of the designated operating boundary. Interim reclamation efforts will take place between the operating boundary and the berm located at the edge of disturbance. The area will be cross ripped 18 inches or to bedrock per COGCC 1000 Series 1003 for Interim Reclamation. Seedbed preparation will consist of scarifying, tilling or harrowing seedbed post ripping. Stage 3: Once substrate preparation has been completed (it is imperative that seeding take place within the same day as the seedbed preparation to eliminate crusting of soils prior to seed application), available topsoil will be distributed across the prepared surface. Drill seeding will be performed at a depth of 0.5 inches, seed will be covered with soil and lightly compacted to ensure good seed to soil contact. Certified weed free straw will be applied at a rate of 2,000 lbs/acre and crimped into place following drill seeding as applicable.
