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, stormwater 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) (Please refer to Ursa's Noxious Weed Management Plan for details). Stormwater 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. 1 Procedures identified in this plan apply 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. Ursa obtains the sole discretion on implementing practices outlined in this plan and ability to change, modify, or alter reclamation practices to accommodate operations and ensure environmental protection. 2 2.0 Site Characteristics Gravel Trend The Gravel Trend natural gas wells and associated infrastructure are located within Township 7 South, Range 95 West, of the 6th P.M. Rifle, Silt, and New Castle, are located along the boundaries of the Gravel Trend field. The Gravel Trend Field has clayey, loamy soils with moderately rapid permeability and an erosion hazard of moderate to severe. Most soils located within the field are deep well drained soils usually found within 5,000 to 7,500 feet in elevation. Typical rainfall per year ranges from 12-18 inches and has a frost free period of 120-125 days. The field mostly encompasses north facing aspects with minor vegetation. For a more information on the different soil types found within the Gravel Trend Field, please refer to Appendix C. North Gravel Trend The North Gravel Trend natural gas wells and associated infrastructure are be located within Townships 4, 5, and 6 South, Ranges 91, 92, 93, and 94 West, of the 6th P.M. Rifle, Silt, and New Castle, are located along the boundaries of the North Gravel Trend field. This field consists of many different soil types which include clayey, loamy soils with moderate to moderately rapid permeability. Erosion hazard ranges from moderate to severe and are found within 5,000 to 7,000 feet in elevation. Annual typical rainfall can range from 12-14 inches and has a frost free period of 120-125 days. The field mostly encompasses south facing slopes aspects with minor vegetation. For more information on the specific soil types found within the North Gravel Trend Field, please refer to Appendix C. Castle Springs The Castle Springs natural gas wells and associated infrastructure are located within Townships 7, 8, and 9 South, Ranges 90 and 91 West, of the 6th P.M. Rifle, Silt, and New Castle, are located near the boundaries of the Castle Springs field. The Castle Springs Field consists of many different soil types which include, loamy soils with rock outcrops with moderate permeability. Most soils are located within the field are found on gently sloping to rolling ridges and mountainsides. Erosion hazard ranges from moderate to severe and are found within 6,500 to 9,500 feet in elevation. Annual typical rainfall can range from 14-18 inches and has a frost free period of 70 to 105 days. The field mostly encompasses north facing slopes aspects with dense vegetation cover. For more information on the specific soil types found within the North Gravel Trend Field, please refer to Appendix C. 3 Battlement Mesa Parachute, Battlement Mesa, and Rulison, are located in or near the Battlement Mesa field, (Township 7South, Range95 West). *Glenwood Springs is located approximately 27 miles to the east 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: temporary reclamation of a site once the site has been constructed and is in production, interim reclamation of site when completions are no longer necessary and the pad has been brought down to only the daily operational use, and final reclamation when a pad is no longer in operation and the well(s) have been plugged and abandoned (P & A). All phases of reclamation will be in compliance with CDPHE, COGCC, and BLM regulations. Pipeline ROWs will have only a temporary and final phase. 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 Stormwater 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 Temporary Reclamation A site has been placed into the temporary reclamation phase, once the site has been constructed and is in production. Temporary Reclamation: • Pads — The areas not used for everyday operations will be broadcast seeded. All temporary and permanent stormwater controls will be installed and maintained. Seeding rate and mix will be determined by land owner. Certified weed free straw may be utilized at 2 tons per acre and crimped into place. • Pipelines —ROW will be monitored and permanent and temporary stormwater best management practices (BMPs) will be installed to control erosion and sedimentation. Once the trench has been backfilled and final grade has been completed, the ROW will be drill seeded. • 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. 3.1.1 Stage One (Removal and Disposal) During reclamation of any site, once the pad/ROW/access road has been constructed, all 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. 5 3.1.2 Stage Two(Planting/Timing) Upon completion of pad construction, all areas not used for production will be seeded. Seedbed preparation will consist of surface roughening. This will occur just prior to seeding. Seed will be applied by hand broadcast. The seed mix for each reclamation project will be an approved Seed Mix (Appendix B). Ideally planting will occur in the fall (See Table 1.), 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 all phases of reclamation, the seed mix associated with this site will be used. 3.2 Interim Reclamation A site enters the interim reclamation phase when the location has finished completions, and no completion work is foreseen in the near future. At this point, the site's footprint will be brought down to only the daily operational use. 3.2.1 Stage One (Removal and Disposal) During interim 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 may be disposed of properly. Temporary BMPs used during the temporary phase of reclamation may be kept and used during interim reclamation. Incorporation of permanent BMPs may be implemented during this phase. 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 stormwater 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 may 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 stormwater 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. 6 3.2.2 Stage Two (Substrate Preparation) The condition of the soil is very important for the establishment of a healthy self- sustaining environment. Locations where noticeable staining exists will have the impacted soil removed or remediated, and disposed of in accordance with County and COGCC waste management regulations (refer to Ursa waste management plan). 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 if possible. Ursa has implemented a beneficial reuse program for drill cuttings within the Battlement Mesa Field. Drill cuttings will be stored on site within containment until the cuttings have met all criteria under COGCC's Table 910 suite, then incorporated into the pad. (Please see Ursa's Waste Management Plan for details.). 3.2.3 Stage Three (Planting/Timing) 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). Ideally planting will occur in the fall (See Table 1.), 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. 3.3 Final Reclamation Final reclamation is when a pad is no longer in operation and the well(s) have been plugged and abandoned (P & A). 3.3.1 Stage One (Removal and Disposal) During final reclamation of any site, all wooden stakes used to secure wattles and straw bales, and other waste associated with construction of the site will be disposed of properly. Temporary BMPs used during the temporary phase and interim phases will be removed and replaced with permanent BMPs as applicable. Any trash left behind on location such as pipe fittings, used lumber or miscellaneous items that have been discarded. During final reclamation of the site, when the pad is no longer in operation, all 7 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. 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 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. 3.3.2 Stage Two (Substrate Preparation) In the final phase of 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 if possible. Ursa has implemented a beneficial reuse program for drill cuttings within the Battlement Mesa Field. Drill cuttings will be stored on site within containment until the cuttings have met all criteria under COGCC's Table 910 suite, and then incorporated into the pad. (Please see Ursa's Waste Management Plan for details.). 3.3.3 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 8 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). Ideally planting will occur in the fall (See Table 1.), 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. 9 4.0 Stormwater Mitigation 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 stormwater impact and capture and retain precipitation. This will aid in the germination of the seed and increase seedling survival. See Ursa's Stormwater Management Plans (SWMPs) for a full list of BMPs and installation details. 4.1 Noxious Weeds Undesirable species such as noxious weeds and pest weeds occur during any type of earth -disturbing activities. Weeds will be monitored and documented. Once identified, they will be treated, as appropriate with the proper herbicide and surfactant. Treatments are typically conducted during the spring, summer and fall to ensure that all cycles and species present are being treated at the appropriate times. On federal lands, a Pesticide Use Proposal (PUP) is required by the BLM for approval for each herbicide prior to treatment. Annual reports regarding weed management and reclamation success will be submitted to Judy Perkins at the Colorado River Valley Field Office in compliance with the Noxious and Invasive Weed Management Plan for Oil and Gas Operators. In accordance with Garfield County noxious weed management, noxious species will be treated before construction activities begin. 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, an 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. 10 5.0 Inspections To meet the requirements of the CDPHE General Stormwater Discharge Permit, inspection and maintenance of erosion and sediment controls must occur during the project. During Ursa's stormwater inspections, reclamation efforts will be reviewed as well. 11 6.0 Data Records Management Inspections, PUPs, and other necessary information that facilitates management and reclamation success will be kept at the Ursa office in Rifle.
