Temporary Reclamation
For disturbed areas that are not used for operational use, meas ' es will be taken to stabilize soils,
maintain biotic soil activities and minimize invasive species in station. Measures include, but
are not limited to; surface roughening, pocking, seeding of to . oil berms/windrows, fill/cut
slopes, and temporarily disturbed areas along road ways. Seeing disturbed areas upon
completion of construction will assist with weed management and sit degradation caused from
wind and stormwater.
Interim Reclamation
Existing gravel on location will be moved to the inside of the designated

Final Reclamation
Final reclamation will occur once production of the well has ceased and it has been p . gged and
abandoned (P &A). The remaining disturbed area, including all access roads as well as the well
pad will be re-contoured to fit existing topography. The goal of final reclamation is to . chieve
vegetation establishment of desired species while moving towards a self-sustaining, vigous,
diverse native plant community that will stabilize soils, control erosion and sediment trans. .rt,
maintain healthy, biologically active topsoil, impede invasion of noxious weeds, and resto

1.0 Introduction
This Reclamation Plan (Plan) describes procedures necessary for reclamation of Ursa
Operating Company LLC's (Ursa) field wide resources located in Garfield County, Pitkin
County, and Mesa County, Colorado. 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.
1
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.
2
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.
3
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
4
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.
5
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.

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.

Ursa Operating Company Noxious Weed Management Plan
1. Introduction
The Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5) declares that certain undesirable
plants constitute a threat to the "continuous economic and environmental value of lands of the
state" and requires that these "noxious weeds" be managed on private and public lands. The Act
further declares that control of noxious weeds should use methods that are least damaging to the
environment but also practicable and economically reasonable. Ursa Operating Company, LLC
(Ursa) started operations in the Piceance on April 1, 2013 and will be responsible for
management of noxious and undesirable species identified on land leased associated with these
assets. The local government(s) management of noxious weeds for Ursa assets (known as
Battlement, Castle Springs, Gravel Trend, North Gravel Trend, Roan, and Wolf Creek), are
Garfield County, Mesa County, and Pitkin County which requires that land owners or persons or
entities leasing the land within the county manage noxious weed infestations on their respective
land.
By implementing a Noxious Weed Management Program, adverse economic and environmental
impacts will be minimized for Ursa and surrounding stakeholders. Maintaining control of
noxious weed populations within Ursa assets is important to keep the cost of noxious weed
abatement, storm water, and revegetation to a minimum. Since the three (3) elements are
intertwined; improvement in one (1) area will facilitate improvements in the other areas of
concern. It is also vital that the expansion of noxious weeds from Ursa assets to private land not
associated with oil and gas exploration is monitored closely to ensure weed abatement measures
are effective. For the most successful management of noxious weeds, regular communication
between Ursa and property owners with adjacent land should be developed.
This plan is intended to provide Ursa with a noxious weed management outline for the area of
concern — in this instance, the assets known as Battlement, Castle Springs, Gravel Trend, North
Gravel Trend, Roan, and Wolf Creek. The objectives of the plan include: providing basic
environmental information about the sites, locating and mapping of noxious weed populations,
outlining and evaluating possible treatment methods, and establishing preventative measures to
minimize noxious weed expansion. This plan will also provide an amendable document for
current and future Ursa land managers.
2. Site Characterization
Ursa assets are located in Garfield, Mesa and Pitkin Counties in western Colorado (refer to
Figure 1 for a map and Appendix A for listed locations). The Castle Springs and Wolf Creek
assets are grouped together and the Roan and North Gravel Trend assets have also been
combined. The assets can be found using the Public Land Survey System (PLSS) in Appendix A
or by reviewing the map in Figure 1.
The vegetative communities that characterize these sites include: sagebrush, rubber rabbitbrush,
snakeweed, Gambel oak, bunch grasses and pinyon -juniper. This highland is characterized by
moderate moisture levels, moderate temperatures and a moderate growing season. Snow is
typically present on site from mid-November to late -March, with an average of 80-90 frost days
per year. The soil type varies across assets. For more information on soil type, refer to Appendix
B and Figure 2.
Ursa Operating Company Noxious Weed Management Plan 1
The potential treatment area with regards to noxious and undesirable species will include
appropriate and applicable pads, right of ways (ROWs) including access roads and pipeline
ROWs, topsoil stockpile if applicable, and land surrounding the Ursa assets that has been
disturbed by related Ursa activity.
3. Weeds of Concern
To meet the requirements of the Colorado Noxious Weed Act (ACT), the operator shall conduct
prescribed management techniques for noxious weeds control and prevention. Species
warranting prescribed management control and prevention are included within the Colorado
Noxious Weed Lists: List A — designated for statewide eradication; List B — managed to prevent
further spread and, for selected species, designated for eradication in large areas; and List C — of
more localized concern, but for which the State will provide education, research, and biological
control assistance to jurisdictions that choose to manage the species. The complete Colorado
Noxious Weed List can be found in Appendix C. In addition to the state wide weed list,
individual counties have their own noxious weed lists. The county lists are comprised of noxious
weeds from the state list that are more specific to the area of concern.
Garfield County has designated twenty (21) of the seventy four (74) species from the Colorado
Noxious Weed List to be likely species found in the vicinity of their jurisdiction. Appendix D
contains the Garfield County Weed List, and specific details can be acquired through the
Garfield County Noxious Weed Management Plan available online.
Mesa County has designated nineteen (19) species as noxious and present within their
jurisdiction. Appendix E contains the complete list, and descriptions can be found in the Mesa
County Noxious Weed Management Plan available online.
Pitkin County has designated thirty five (35) species to be noxious and of concern within its
jurisdiction, with an additional five (5) species on their so-called "Watch List" as they have
spread to and within neighboring counties. Appendix F contains the Pitkin County Noxious
Weed List, and details can be obtained through the Pitkin County Noxious Weed Management
Plan available online.
4. Weed Inventory
Noxious weed surveys are currently being conducted on Ursa assets. For a visual representation
of the survey please refer to Appendix G. The respective appendix will be updated annually to
monitor the spread and or minimization of infestations. Additional surveys will be conducted
annually by qualified individuals to ensure noxious weed treatments and noxious weed
populations. Populations of noxious weed infestations will be mapped by qualified individuals
using global positioning units (GPS) units. The Noxious Weed Inventory Form, Appendix H,
can be used to provide supplemental survey information if the surveyor deems it appropriate.
The surveys will provide a way to identify new noxious weed populations as well as an
assessment tool for previously treated populations. The inventory is to be updated as the surveys
are performed. There will be an annual review to assess the overall noxious weed populations
and success of treatments applied.
Ursa Operating Company Noxious Weed Management Plan 2
5. Treatment Methods
The treatment methods and descriptions listed below were obtained from the Mesa County
Noxious Weed Management Plan (Mesa County, 2009). Management techniques include
preventative, cultural, physical/mechanical methods, biological and chemical approaches.
Optimal noxious weed management methods will vary with the environmental variables of the
area of interest. Soil type and stability, grade, moisture regimes, growing season, pre-existing
noxious weed populations, land use, water availability, weed type and stage of growth as well as
the intensity of the infestations should all be taken into account when preparing a noxious weed
management plan.
The management methods should have minimal impact on the environment and be economically
fitting for the Operator in charge of implementing the noxious weed management program.
When assessing weed management on a property, it is important to evaluate possible modes of
transportation for the noxious species. Areas to take into account include; waterways, roads,
game trails, areas with livestock and equipment storage sites to name a few possibilities. The
transportation of noxious species is a problem shared by all the stakeholders in the affected area.
Good communication should be established between the affected parties for proper management
of the noxious weed populations. Most management plans utilize a combination of the treatments
outlined below.
5.1 Preventative Methods
Preventative methods include practices involving good land stewardship. These practices
include, but are not limited to; using weed free certified products, erosion control
measures, and regularly cleaning equipment.
5.2 Cultural Methods
Cultural methods facilitate competition from desirable plants through actions such as;
dense seeding, irrigation, carefully monitored grazing practices and fertilization.
5.3 Physical and Mechanical Methods
Physical and mechanical methods include mowing, disking, hand removal, plowing,
burning and solarization. The goal of these methods is predominantly to prevent seed
production. Roots should be severed at least two (2) inches below the soils surface for
optimal control.
5.4 Biological Control Methods
Biological control methods involve the introduction of living organisms that are
deleterious to the noxious weed species. This method is only applicable for infestations
larger than five (5) acres in size, and rarely provides complete control of the noxious
species. Frequent monitoring must be carried out with this method.
5.5 Chemical Control
Chemical control can offer the most effective means of noxious weed control when
applied at the appropriate time. Not all herbicides are equally effective against all weeds,
nor can every herbicide be used in all settings. The respective herbicide applicator should
consult with a weed manual before applying any herbicide to the land.
Ursa Operating Company Noxious Weed Management Plan 3
6. Treatment Recommendations
6.1 Pad Surfaces
It is recommended that the area directly adjacent to structures be treated with a bare
ground herbicide. The bare ground treatment will be applied once a year or as needed to a
ten (10) foot perimeter around the structures located on Ursa developments. All other
areas are to be spot treated with an appropriate herbicide.
6.2 ROWs and Surrounding Lands
Ursa assets should be treated with a selective herbicide appropriate for the species where
the noxious weed is found. The appropriate chemical to be applied will be determined by
the licensed herbicide applicator. The specific herbicide applied will vary depending on
the landowner, time of year and the stage of growth the plant has obtained at the
proposed treatment date. The Bureau of Land Management (BLM) must be contacted
prior to treatment on Federal lands.
6.3 Special Requirements
At this point in time there are not any special requirements for Ursa assets or the
associated ROWs with regards to management of noxious weeds or other undesirable
species. Any and all special requirements will be amended to the document as soon as
practicable.
7. Management Strategies
7.1 Prevention
Taking preventative measures to abate the spread of noxious weeds is critical for proper
land management. Noxious weeds can become established on or near disturbed land very
rapidly and have the capacity, capability and potential to spread quickly to other areas.
Noxious weed seeds and vegetative matter can be transported by means of animals,
vehicles, shoes, and hay to name a few examples of transportation. Operators should be
aware of established noxious weed populations and the possible transport mechanisms on
their property and surrounding properties.
7.2 Revegetation and Rehabilitation
After an area has been successfully eradicated of noxious species, or before establishment
has taken place, actions to revegetate the disturbed area should be taken to minimize the
chance of noxious weed establishment. If the disturbed land has desired species growing
as a result of revegetation efforts, competition with noxious species will be increased.
Therefore, the potential and capability of the noxious weed to establish in the disturbed
area is limited.
Noxious weed management strategies for Ursa will include a monitoring program.
Surveys will be carried out between the months of April and October. Noxious weed
populations will be monitored at this point through qualitative visual interpretation as
well as mapping.
Ursa Operating Company Noxious Weed Management Plan 4
8. Conclusion
This noxious weed management plan provides an outline for the treatment and management of
noxious weeds. Please refer to Appendix I for the Noxious Weed Summary Documents which
provide contact information as well as general information pertaining to Ursa assets. An annual
report will be compiled to assess the overall management program.
Noxious weed control is critical to guarantee the environment is preserved for future generations
to enjoy and utilize. Adhering to this management guide will aid Ursa in managing noxious
weeds encountered during active involvement at developed sites.
These recommendations are not intended to be used as a definitive guide for noxious weed
management. Herbicide recommendations are available from both the state and local
governments and/or licensed applicators.
