1.0 PROJECT OVERVIEW
1.1 Background
EnCana Oil and Gas (USA) Inc. (EnCana) is requesting authorization from Garfield County to
install and operate a 60-foot self-supporting communication tower in the NEl/4 SWl/4 of
Section 30, Township 7 South, Range 95 West, 6'h P.M. The proposed communication tower will
serve as a remote communication link from the EnCana office located in Parachute, Colorado to
the High Mesa Water Plant, the High Mesa Compressor Station, and the Orchard Compressor
Station.
1.2 Description
The proposed communication tower will be installed on the existing PN30 well pad. The PN30
well pad is located on both Bureau of Land Management (BLM) land and the Daybreak Realty
LLC property. However, the tower will be installed on the Daybreak Realty LLC property,
which is located to the northeast of the BLM property. The proposed tower is located at a site
that will not interfere with future well production operations and the tower site will not impede
future well pad reclamation activities. The total area necessary for the installation and operation
of the tower will be an 85-foot by 85-foot area. The location map and site plan are provided in
the Site Plan Tab.
The communication tower will be constructed off-site at the manufacturer's office, and brought
to the site for installation. Since the site is located on a previously disturbed well pad, minimal
grading will be necessary. An area of stockpiled topsoil will need to be temporarily relocated to
construct a level ground surface. After grading is completed the concrete piers for the tower
supports and guide wire anchors will be installed. The communication tower will be transported
to the site via tractor-trailers and erected by a construction crew. Installation of the tower will
take approximately three days after the concrete piers have properly cured.
The tower will be powered by a solar power unit located at the site and an electric control
building will be installed at the base of the tower. No additional electric power services will be
necessary for operation of the tower facility. The tower will be used to provide wireless LAN
network connections in unlicensed frequency ranges, so the tower facility will not require
Federal Communication Commission licensing. Specifically, the frequencies will be 2.4 GHz
(2400-2483.5) and 5.8 GHz (5725-5850 MHz) unlicensed frequency ranges.
1.3 Purpose and Need
The proposed communication tower will serve as a remote communication link from the EnCana
office located in Parachute, Colorado to the High Mesa Water Plant, the High Mesa Compressor
Station, and the Orchard Compressor Station. The proposed tower will allow remote monitoring
and operation from the EnCana office located in Parachute, Colorado of natural gas processing
and water recycling facilities in the South Parachute and Orchard lease units.

Use and Zoning Regulations.
2 Special Use Pern1it Application Narrative
June 2007
·.Parachute Communication Tower
2.1 Water and Sanitation Utilities
Portable toilets will be available on-site and potable water will be transported from off-site and
made available to personnel. EnCana would not construct any permanent water or sanitation
utilities.
2.2 Access
Vehicle access to the proposed South Parachute Communication Tower will require traveling on
Garfield County roads 300 and 304, and then vehicles will follow a private road crossing through
Sections 36, 31, and 30 in Township 7 South, Range 95 West. County Road 300 is the only
paved road on the project route; the remaining roads are improved gravel roads, mostly used by
the oil and gas industry and local ranchers. Since the road accessing the site is a private roadway
a Garfield County Driveway Permit will not be necessary for construction of the project.
2.3 Neighborhood Character
The proposed South Parachute Communication Tower is located on the south slope of High
Mesa, and is surrounded by mature pinion/juniper forests. The nearest residence is 1.63 miles
northeast of the communication tower. The steep topography and heavy vegetation surrounding
the proposed communication tower will block the majority of visual impacts from public
roadways.
Installation and operation of the communication tower would not change the existing
neighborhood character.
3.0 SECTION 5.03.07 INDUSTRIAL OPERATIONS
The following sections address impacts as required by Section 5.03.07 of the Garfield County
Land Use and Zoning Regulations.
3.1 Existing Lawful Use of Water
No water depletion would occur as part of this project. EnCana has prepared and utilizes the
Stormwater Management Plan (SWMP) and the Spill, Prevention, Control and Countermeasure
Plan (SPCCP). Implementation of these plans ensures that activities comply with stormwater
management and spill prevention controls and countermeasures as required by Garfield County,
the State of Colorado, and the United States Environmental Protection Agency. Implementation
of these plans also ensures that EnCana would not pollute surface runoff, stream flow, or
groundwater. Copies of the SWMP and SPCCP are provided in the Stormwater and SPCCP Tab.
3.2 Generation of Vapor, Dust, Smoke, Noise, Glare or Vibration
No vapor, dust, smoke, noise, or vibration would be produced as a result of this project. Minor
glare could possibly occur from the installation of the tower; however, the glare would not be
noticeable at the surrounding public roadways.
Special Use Permit Application Narrative

South Parachute Communication Tower
3.3 Wildlife and Domestic Animals
EnCana has contracted WestWater Engineering Inc. to prepare a Wildlife Assessment and
Mitigation Plan for the proposed South Parachute Communication Tower, which is included in
the Supporting Documentation Tab. The assessment determined that the communication facility
location and immediate vicinity was poor quality wildlife habitat. Installation of the
communication tower inside the disturbed area would not create additional adverse impacts to
wildlife or domestic animals in the project area.
3.4 Traffic Impacts
Approximately one vehicle, once a month will access the tower facility to perform any necessary
maintenance and ensure correct operation. Construction of the tower will occur off-site at the
manufacturer's office. Installation at the site will take approximately three days (six man-days).
Vehicles accessing the site during installation of the tower will involve two pick-up trucks per
day, one tractor-trailer delivery of the tower and related tower equipment, and one equipment
crane will access the site for placement of the tower. Vehicles accessing the site will utilize a
private road off of Garfield County Road 304.
3.5 Abutting Property
The BLM property immediately south of the proposed communication tower is the nearest
adjacent property owner. No damage from operations of the communication tower would occur
to adjacent property.
3.6 Reclamation Plan
Prior to abandonment of the South Parachute Communication Tower, EnCana would contact the
Garfield County Planning Director to arrange for a meeting and joint inspection of the tower
facility. This meeting and inspection would take place a minimum of 30 days prior to
abandonment, and would be held so that an agreement on an acceptable abandonment plan can
be reached.
EnCana will complete final reclamation measures in areas that are not necessary for operation of
the communication tower facility. Topsoil will be segregated during the grading of the tower pad
site and saved for reclamation at a later date. After the completion of the tower installation the
topsoil will be re-contoured around the tower facility. Seeding will be performed with a seed
mixture approved by the surface owner. The seed mixture will be broadcasted over the ground
surface and hand-raked into the upper soil surface. Revegetation will be considered successful
when the vegetation is at least 70% revegetated with desirable species compared to areas
adjacent to the tower facility.
3.7 Emergency Response Plan
EnCana would comply with its Emergency Response Plan (ERP), which describes the functional
roles and accountabilities for life safety, property damage, and environmental response. The ERP
also describes the communication and notification protocols to engage support, based on the
nature and complexity of the emergency. The ERP is included in the Emergency Response Tab.
4 Special Use Pern1it Application Narrative
June 2007
i Parachute Communication Tower
EnCana would reimburse the appropriate emergency service provider for costs incurred m
connection with emergency response for activities associated with this project.
4.0 SECTION 5.03.08 INDUSTRIAL PERFORMANCE STANDARDS
All operations at the proposed South Parachute Communication Tower would comply with
applicable county, state, and federal regulations regulating water, air, and noise pollution and
would not be conducted in a manner constituting a public nuisance or hazard. Operations would
be conducted in a manner as to minimize heat, dust, smoke, vibration, glare and odor and all
other undesirable environmental effects beyond the boundaries of the property. The following
section address compliance with the standards set forth in Garfield County Zoning Regulations
5.03.08.
4.1 Sound Volume
No increase in sound volume would occur from the construction and operation of the
communication tower.
4.2 Vibration
No increase in vibration would occur from the construction and operation of the communication
tower.
4.3 Smoke and Particulate Matter
Smoke would not be produced as a result of this project. EnCana would apply water, gravel,
tackifier, or other equivocal measures as necessary to prevent fugitive dust emissions from
equipment and/or vehicles traveling in the project area.
4.4 Heat, Glare, Radiation, and Fumes
No heat, radiation, or fumes would be produced. Glare would be minimized by the thick
pinion/juniper forest surrounding the tower facility and remote location of the tower from
existing public roadways. Adjacent property would not be affected and a public nuisance or
hazard would not be created.
4.5 Storage
Construction and operation of the tower facility would not require any temporary or permanent
storage of waste products, hazardous or non-hazardous products, or equipment. No wastes will
be produced by the construction and operation of the South Parachute Communication Tower.
Lighting will not be necessary for the operation of the communication tower.

SURF ACE USE CONDITIONS OF APPROVAL
I. The paint color to be used on all surface facilities, including any metal containment rings surrounding
the tank batteries, is Shale Green (SY 4/2).
2. The operator is responsible for applying dust abatement measures as needed or directed by the
Authorized Officer. The level and type of treatment (watering orapplication of various dust agents,
surfactants and road surfacing material) may be changed in intensity and must be approved by the
Authorized Officer. Dust control is needed lo prevent heavy plumes of dust from road use that create
safety problems and disperses heavy amounts of particulate matter on adjacent vegetation.
3. Noxious weeds, which may be introduced due to soil disturbance associated with the proposed lease
operations, will be treated by methods to be approved by the Authorized Officer. A Pesticide Use Plan
(POP) is required prior to use of any pesticide.
4. Remote monitoring will be conducted during the winter months to minimize site visits to pad locations
and reduce !raffle impacts to wintering big game wildlife. In addition, scheduled winter visits (those
other than for emergency purposes), should be scheduled between 10 a.m. and 3 p.m. to further minimize
disturbance to wintering big game wildlife.
5. The pad layout as shown on Sheet 9 of 15 (dated 2/11/05) shall be amended to reduce the width of
reserve pit by 30 feet and extend length of pit 30+ feet to south thereby pulling the east side of pad back
to the edge of original pad disturbance. Furthermore, the 25 foot wide bench on east side of µit will be
reduced to maximum 1 0 foot wide bench.
6. Although there is no specific Timing Limitation for 13ig Game Winter Habitats listed in the Lease, the
60 day Condition of Approval for Big Game Habitat idrntified in Appendix D-1 in the GSRA Oil & Gas
Final SEIS (approved March 24, 1999) will be invoked. This COA states: "To protect crucial big game
winter range on leases 'vithout ti1ning restrictions, construction and drilling activities arc prohibited. fro1n
January 15 through March 15."
The rationale for invoking this COA is based on field rev1e\V and the updated Colorado Division of
Wildlife fiig Game Winter Habitat mapping which clearly identifies the well location and access road
within these cn1cial winter ranges.
7. Cultural Resource Education/Discovery Stipulation
All persons in the area who are associated with this project must be informed that if anyone is found
disturbing historic, archaeological, or scientific resources, including collecting artifacts, the person or
persons \Vill be subject to prosecution.
Pursuant lo 43CFR10.4(g), the BI.M authorized officer must be notified, by telephone, with written
confirmation, immediately upon the discovery of human ren1ains, funerary items, sacred objt:cts, or
objects of cultural patrimony. Further, pursuant to 43CFRI0.4 (c) and (d), activities must stop in the
vicinity of the discovery and the discovery must be protected for 30 days or until notified to proceed by
the authomed officer.
If in connection \Vi th operations under this contract the project proponent) his co11tractors, subcontrnCtors,
or the ctnp1oyces ofnny ofthern, dist:ovcrs, encounters or bccotncs a\varc of any objects or sites of
cultural or paJcontological value or $(.;it:ntific interest such as historic. or prehistoric ruins, graves or grave

markers, fossils, or artifacts, the proponent shall immediately suspend all operations in the vicinity of the
cultural or paleontological resource and shall notify the BLM authorized officer of the findings (16 U.S.C.
470h-3, 36CFR800.I 12}. Operations may resume at the discovery site upon receipt of written
instructions and authorization by the authorized officer. Approval to proceed will be based upon
evaluation of the resource. Evaluation shall be by a qualified professional selected by the authorized
officer from a federal agency insofar as practicable. When not practicable, the holder shall bear the cost
of the services ofa non-federal professional.
Within five working days the authorized officer will info1m the holder as to:
-whether the materials appear eligible for the National Register of Historic Places;
-the mitigation measures the holder will likely have to undertake before the site can be used
(assuming in situ preservation is not necessary); and,
-a time frame for the authorized officer to complete an expedited review under 36 CFR
800. l l, or any agreements in lieu thereof, to confirm through the State Historic Preservation
Officer that the findings of the authorized officer are COtTect and the mitigation is appropriate.
The proponent may relocate activities to avoid the expense of mitigation and/or the delays associated with
this process, as Jong as the new area has been appropriately cleared of resources and the exposed
materi~ls are recorded and stabilized. Otherwise, the proponent will be responsible for mitigation costs.
The authorized officer will provide technical and procedural guidelines for the conduct of mitigation.
Upon verification from the authorized officer that the required mitigation has been completed, the
proponent \viii then be allowed to resume construction.
Antlquitics, historic, prehistoric ruins, or objects of scientific interest that are outside of the authorization
boundaries but directly associated with the impacted resource will also be included in this evaluation
and/or mitigation.
Antiquities, historic, prehistoric ruins, or objects of scientific interest, identified or unidentified, that are
outside of tlie authorization and not associated with the resource within the authorization will also be
protected. hnpacts that occur to such resources, which arc related to the authorizations activities, will be
mitigated at the proponent's cost including Native American consultation cost.
8. All persons associated with operations under this authorization must be informed that any objects or
sites ofpalcontological or scientific value, such as vertebrate or scientifically important invertebrate
fosslls, shall not be damaged, destroyed, re1novcd, moved or disturbed. If in connection \Vith operations
under this authori7.ation any of the above resources arc encountered the proponent shall immediately
suspend all activities in the immediate vicmity of the discovery that might further disturb such materials
and notify the BLM authorized officer of the findings. The discovery must be protected until notified to
proceed by the authorized officer.
As feasible, the proponent shall suspend ground-disturbing activities at the discovery site and
immediately notify the BLM authori?.ed officer of any finds. The BLM authorized officer will, as soon
as feasible, have a BLM-permittcd palr.ontologist check out the find and record and collect it if warranted.
If ground-disturbing activities cannot be immediately suspended, the proponent shall work around or sel
the discovery aside in a safe place to be accessed by the BLM-pem1ittcd paleontologist.
9. Reclamation Plan. Refer to Appendix I. Surface Reclamation of the 6/98 GSFO's Dratl Supplemental
EIS for Oil & Gas Leasing Development (pages 1-1 through 1-8) for specific reclamation goals,
objectives, timelines, measures and monitoring methods. These guidelines will be followed in
completing the reclamation of disturbed surfaces on well pads, access roads and pipelines
Wells: Federal 30-11, 30-1 lBB, 30-14BB, 30-15, 30-15BB & 31-2BB
PN30Pad
Operator: EnCana Oil & Gas (USA) Inc.
Some effective practices that will be implemented during reclamation include, but arc not limited to:
proper siting of the well pad to minimize impacts, the immediate seeding of disturbed areas after
construction, proper storage and rcdistribulion of topsoil, reshaping cut and fill slopes, seeding with
specified seed mix within the first available growing season after disturbance, deep ripping(> 18 inches
on 2 foot centers), fencing reclaimed areas to protect from livestock use, and the use ofriprnp, slash or
other erosion control structures to help control sediment loss.
The 4 Reclamation Categories defined on Page 1-8 of Appendix I (6/98 GSFO's Draft Supplemental EIS
for Oil & Gas Leasing Development) will be used in gauging the progress of reclamation monitoring.
Seed Mix Ap_pjjcati9_11~Practicc~
A specified seed mix designed to meet interim reclamation standards while providing forage and browse
for wintering elk and deer using a mixture of shrub, grass and forb species shall be applied. The
following seed mix and rates will be used on all disturbed surfaces, including pipelines unless otherwise
noted in the specific APD:

14.0 lbs. PLS/acre Total
The above rate of application is listed in pounds of pure live seed (PLS)/acre. The seed will be certified
and there will be no primary or secondary noxious weeds m the• seed mixture. The operator shall notify
the Authorized Officer 24 hours prior lo seeding and shall provide evidence of certification of the seed
mix to the Authorized Officer within 30 days of completion of the seed application.
Upon completion of backfilling, leveling, ripping to minimum 18 inch depth on 2 foot centers, and
recontouring, the stockpiled topsoil will be evenly spread over the reclaimed arcas(s). Prior to reseeding,
all disturbed surfaces will be scarified and left with a rough surface. No depressions will be left that
would trap \Vatcr and form ponds.
The prepared seedbed will be seeded within 24 hours after completing dirt work unless a change is
requested by the operator and approved by the Authorized Officer. Prepare the seedbed by contour
cultivating 4-6 inches deep. Drill seed ~to Y2 inch deep following the contour. In areas that cannot be
drilled, broadcast seed at l Y, times the application rate and cover Y, to 1 inch deep with a harrow or drag
bar. All seeding will be conducted a!\er September I and pnor to ground frost. Spring seeding will be
done after the frost leaves the ground and no later than May 15"'. lf the seeding is unsuccessful, operator
will be required to inakc :-;ubscquent seedings until the rcclarnation objectives identified in Appendix I.
Surface Reclamation of the 6/98 GSFO's Draft Supplemental EIS for Oil & Gas Leasing Development
are met.
Erosion Control Practices
11le cut and fill slopes will be protected against ri11ing and erosion with rncasurcs such as \Valer bars,
lateral furrows, or other rncasurcs approved by the Authorized Officer. Weed free straw bales, stra\v
Wells: Federal 30-l J, 30-11 BB, 30-14BB, 30-15, 30-ISBB & 31-2BB
PN30Pad
Operator: EnCana Oil & Gas (USA) Inc.
"wattles'', straw matting or a well-anchored fabric silt fence will be used on cuts and fill slopes to protect
against soil erosion.
Topsoil Practi<;i;>
During well pad, road and/or pipeline construction, topsoil will be stripped to a minimum depth of 6
inches and segregated from other subsurface material piles, ie. excess material from reserve pit
construction. If topsoil is less than 6 inches, the top 6 inches of surface material will be stripped and
piled.
Site Protectio111'J''1Ctices
Reclaimed areas will be fenced to exclude livestock until seeded species have established. The
Authorized Officer will approve the type of fencing. Fencing shall be to BLM standards. Existing
cattleguard on site will be maintained in usable condition to prohibit livestock access on the pad.
The operator will submit an arumal reclamation report by December 31 to the Authorized Officer. The
rnport will document compliance with all aspects of lhe reclamation objectives. 'Ihe report will specify if
the reclamation objectives arc likely to be achieved and actions needed to meet these objectives.

South Parachute SWMP EnCana E&P
1.0 INTRODUCTION
This Storm Water Management Plan (SWMP) is written to comply with the Colorado
Department of Public Health and Environment's (CDP!·IE) General Permit No. COR-
03000 issued on June 30, 2002 and will expire on June 30, 2007, and related U.S.
Enviromnental Protection Agency (USEPA) National Pollutant Discharge Elimination
System (NPDES) storm water regulations. The location specific pe1mit for the South
Parachute Area is COR-038210.
EnCana has two operational units that conduct natural gas activities within the South
Parachute Area under COR-038210. These units are Exploration and Production (E&P)
and Gas Gathering. The E&P unit is charged with construction, operation and
maintenance of access roads and well pads while the Gas Gathering unit is charged with
constrnction, operation and maintenance of pipelines and facilities. Both E&P and Gas
Gathering groups are responsible for implementing storm water management as it
pertains to their respective operations within the South Parachute Area. Each group
develops and maintains SWMPs that are suited to the different operations. Therefore,
within an area of operations (such as South Parachute) both E&P and Gas Gathering will
implement their own storm water program which will be maintained separately while
operating under the single CPDS permit.
This SWMP is in two parts: (1) The field-wide SWMP for EnCana's E&P unit activities
within the South Parachute Arca; and (2) additional, dynamic, information (including
inspection forms) for specific well pads, access roads, water pipelines (other than tho>e
lying in the same ROW as gas gathering lines) and associated facilities. The field-wide
SWMP includes a general area description, area boundary map, descriptions of BMPs,
description of materials handling and spill prevention, inspection and maintenance
procedures, and definition of final stabilization. Site-specific tables within this field-wide
SWMP (see Appendix C) address individual ground-disturbing activities (i.e. access
roads and well pads). The site-specific information contained in the Inspector's log
books or archives contain infonnation such as facility location, construction limits, 13MP
locations and detailed current site conditions. Additional information on EnCana's
spcei fies of administrative operations is provided in Appendix C. This SWMP is
intended to address storm water management at all E&P disturbed areas within the South
Parachute natural gas development area (i.e., pads and access roads) and may 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 rnay need to be updated during the project life. Updates may include:
1. Revision of existing BMPs as needed to address erosion-and sediment-control,
and
2. Deletion of BMPs and reduction in monitoring frequency for individual facility
locations where interim and long-term stabilization have been successfolly
established.

1.1 Stom1 Water Run-off Pennitting 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 puhlished final regulations that established application
requirements for storm water associated with construction activity for soil disturbances of
5 acres or more be regulated as an industrial activity and covered by an NPOES pennit.
In December 1999 the lJSEPA published final Phase II NPDES regulations that
established application requirements for stonn 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.
On June 30, 2005, Colorado stonn water regulations went into effect to require Colorado
Discharge Permit System (CPDS) permits for stonn water discharges from construction
activities for small (1 to 5 acre disturbance) oil and gas <1ctivitics. Federal permit
coverage for these discharges was conditionally exempted from the Federal Clean Water
Act by the 2005 Federal Energy Bill. However, on February !, 2006, the CDPHE issued
a letter clarifying that the CDPHE Water Quality Control Commission decided to
maintain the existing requirements for storm water permitting for oil and gas construction
sites.
1.2 Project Description and Background
The South Parachute Area is a grouping of oil and gas leases and associated development
that covers approximately 11,000 acres in Townships 7 and 8 South, Ranges 95 and 96
West, in Garfield County. The area is a combination of Federal and private surface and
minerals. EnCana Oil & Oas (USA), Inc. (EnCana) is the project operator, developer,
and is actively conducting exploration and development ofthc natural gas resource.
Currently there arc actively producing wells and natural gas facilities within the South
Parachute Area. New disturbance may occur as additional access roads and well pads are
constructed.

2.0 CONSTRUCTION SITE DESCRIPTION
2. l Site Location and Construction Area Description
There are existing oil and gas facilities within the South Parachute Arca located in
Garfield County (see Figure l ). New facilities and well pads will be constrncted using
conventional cut and fill earthmoving techniques and new access roads will connect the
well pads to existing roads. Typically, the working pad surface will range from 2 to 5
acres. Reserve pits, when existing, will have a surface area of between 15,000 and
45,000 square feet. Typical well pad layouts arc shown on Figures 2 and 3. Specific pad
dimensions vary depending on the planned drill rig, number of wells to be drilled from
each pad, and local conditions. Pits will be designed, constrnctecl, and reclaimed
according to Colorado Oil and Gas Conservation Commission (COGCC) requirements.
As listed in Section 1, the total surface area within the South Parachute Arca is
approximately 11,000 acres. Development of the natural gas resource and related
facilities within the area is estimated to result in a total disturbance area of 440 acres.
Typical operational phases for a well pad include access road and well pad construction,
well drilling, well completion, well frac'ing, constrnction of production facilities, and
interim reclamation of the well pad into a long-term production configuration. The
"construction" phase well pad configuration is shown on Figures 2 and 3. Pads may
remain in this configuration from 6 months to two years depending on the number of
wells to be constructed on each pad. Drilling, completion, frac'ing, and insta.llation of
production facilities are conducted while the pad is in this "construction" configuration.
After all wells 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 rcvcgctated after grading activities have been completed.
This "interim reclamation·· phase will exist until 70% stabilization (including
rcvcgetation, 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 Bi'v!Ps. Additionally, as pennanent production
facilities are constructed on the pad, a spill prevention and countermeasures control plan
(SPCC) will be prepared for the location. The well pad will remain in the "final
stabilization'' phase of the long-tenn production configuration for as much as 30 years or
more (typically, until the wcll's production declines to sub-economic levels). After all
wells have been plugged and abandoned and surface facilities removed, the well pad will
be graded to restore approximate pre-disturbance contours and will he revegetated.
In areas that arc 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.

South Parachute SWMP EnCana E&P
Nearby drainages will be protected by appropriate measures. Diversion methods will be
assessed which may best redirect inigation and/or stonnwatcrs from coming in contact
with disturbed acreage (i.e., pads and access roads). The surface of the well pad will be
graded to drain standing water to retention ponds that may, upon inspection, have their
waters discharged off-site (requirements for sediment and chemical removal will be met
p1ior to any off-site discharge).
Drilling a natural gas well typically requires 5 to I 0 days, conditions permitting.
Subsequent completion may take several days. Testing of completed wells may take
from a few weeks to several months. If acceptable production is achieved, the wells will
be shut-in until galhe1ing lines and production facilities are constmcted. Once all drilling
and completions are finishcrl encl all pipelines anrl fac.ilitics installccl, the pacl should be
graded to a reduced surface area of approximately I acre. Where practical, cut and fill
slopes will be tapered to at least 2: I (horizontal: vertical). Access roads will remain in
place for well operation and maintenance activities.
If all wells on a pad are not productive, the wells will be plugged according to COGCC
rules and the pad area reclaimed to approximate pre-construction contours. Reclamation
and final stabilization will be conducted as described in Section 4. Note that the
proposed well pads generally contain multiple wells and it is considered unlikely that all
wells on a given pad will be non-productive.
In addition to the well pads, other disturbances will occur as needed to construct access
roads, gathering and sales pipelines, staging areas, natural gas treatment and compression
facilities, and other areas needed for production of natural gas. This SWMP is intended
to address all activities conducted by the E&P unit within the boundaries of the lease
areas. Th.is SWMP may be appended by site-specific information kept in the appendices
of the SWMP or in the Inspection Logs (in possession of the Stonnwater Inspector or in
archived files in the Parachute office).
2.2 Schedule of Constrnction Activities
Natural gas exploration, development and production activities are currently underway
within South Parachute. Stormwatcr rnnnagcmcnl on existing and future well pads and
facilities is covered by this SWMP. for new distmhanccs, flMPs will be installed prior
to, during, and immediately following constnrclion as practicable with considcrntion
given to safety, access (multiple concurrent and/or subsequent operntions al a single site
may make access impractical and/or unsafe) and ground conditions (e.g. frozen ground)
al the time of construction. Development of the natural gas resource and construction of
necessary improvements on this property will likely continue for the next 3 to 5 years.
Recovery of natural gas from these constructed facilities will most likely continue for the
next 30 years or tnore.

South Parachute SWMP EnCana E&P
2.3 Run-off Characteristics
Run-off characte1islics are based on site topography, soil type, and soil/vegetative cover.
Surface elevation ranges from approximately 5,500 to 9,000 feet. Surface soils range
from sands, silts, and clays to exposed bedrock. Slopes range from 1 to over 100 percent.
Existing and future facilities are typically located on valley floors and hillsides. Run-off
coefficients for undisturbed areas are expected to range from 0.1 to 0.4. Run-off
coefficients for disturbed areas are expected to range from 0.1 to 0.6, depending on
surface materials and treatment (e.g. bare soil, gravel surface, surface roughening, etc.).
Refor lo Appendix C in this SWMP for site-specific pre-and post-construction run-off
coefficients.
2.4 Existing Vegetation
The South Parachute Area landscape includes relatively flat mesas, steep slopes, incised
drainages, areas of natural erosion, and alluvial valley bottoms. The area has been
predominantly and historically been used for livestock grazing. Recently, there has been
an increase in residential and natural gas development activities. Arca vegetation
includes a mix grass, shrub, and woodlands species with the dominant vegetation type
depending on slope and aspect. Vegetative cover in the area ranges from 0 to 100
percent. Refer to Appendix C in this SWMP for site-specific detail on vegetation type
and vegetative ground cover.
2.5 Receiving Waters
The South Parachute Arca is located south of the Colorado River. Area drainages arc
primarily intermittent include the following: Battlement Creek, Monument Gulch, Stone
Quan-y Gulch, Dry Creek, Pelc and Bill Creek, and unnamed tributaries. Refer to
Appendix C in this SWMI' for site-specific detail on nearby drainages.
2.6 TIU'eatened and Endangered Species and Historic Places
Analysis of enviro11111cntal effects ((x iltture projects located on FlLM lands is required by
the National Environmental Policy Act (NEPA). This analysis is typically presented in
an Environmental Assessment (EA) prepared by the BUv! or a third-party contractor.
l'icld surveys are conducted to assess the presence of threatened and endangered or
special status plant and animal species. l'icld surveys are conducted to check for the
presence of archcological artifacts. The EA also analyzes the environmental affects of
the proposed action with respect to plants, animals, soils, recreation, and air and water
quality. As needed, measures are specified to mitigate environmental affects caused by
the project or the project may be redesigned to avoid detrimental affects. FlLM wi II also
South Parachute SWMP EnCana E&P
request cultural surveys on portions of new pr()jects portions that occur on privately
owned lands and arc connected to proposed actions on BLM land.

South Parachute SWMP EnCana E&P
3.0 POTENTJAL 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;
• Drill cuttings and drilling fluids;
• Well completion fluids;
• Produced water; and
• Magnesium chloride or other dust suppressants.
The most common source of pollution from constmction sites is sediment, which can be
carried away from the work site with stonn water run-off 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 arc used
in natural gas field construction activities to power, lubricate or cool equipment, <rnd
include fuel, gear oil, hydraulic oil, brake lluid, antifreeze and grease.
Debris from laydown areas, residue from equipment cleaning nnd 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. Other
materials on-site will include compressed gasses used in welding and chemicals used and
stored on-site for use in drilling and well completion.
Drill cuttings and drilling fluids are generated during well construction. These will be
placed in the reserve pit or portable tanks during drilling operations. Although a spill of
these materials is unlikely to occur, these fluids can be potential storm water pollutants.
Magnesium chloride solution or other chemical dust suppressants may be applied during
the summer to unpaved roads to order to reduce fugitive dust generation. l'vfagncsi um
chloride solution is used in the winter for roadway deicing and in the sununer for dust
suppression by county and state government entities. The solution is typically delivered
to the site by contractors in DOT approved tanker trailers and generally is quickly applied
to the road surface.· Occasionally, depending on work site conditions, the tanker trailers
may be staged along the road until ready for application, but this is a rare occurrence.
See Appendix C (Table I) for potential pollutants associated with specific sites.

4.0 DESCRIPTION OF CONTROL MEASURES
4.1 Soil Erosion and Sediment Controls
The objective of erosion and sediment controls is lo minimize the release of sediments to
stonn water run-off. This can be accomplished through the use of structural and/or
nonstructural controls. This section describes erosion and sediment controls to minimize
possible sediment impacts lo stonn water run-off at sites which have not yet reached the
final stabilization phase. Proposed well pad erosion control features may include:
• Placement ofa soil stockpile at the upstream edge of well pads to divert run-on;
• Tnstallation of benn/cham1el at or below the toe of fill slopes which will direct
run-off and convey it to a catch basin;
• Installation of check dams in areas of concentrated flow;
• Temporary seeding of well pads and stockpiles, especially at those pads expected
to remain in the construction phase for a prolonged pe1iod (sometimes greater
than a year); and
• Permanent seeding of well pads where all wells have been drilled, completed,
production facilities installed, and the pad slopes have been regraded to the long-
term, production configuration.
The types and locations of structural BMPs for each disturbed area will be determined as
development progresses and construction plans are prepared (t:r1)ically the application for
pe1111it to drill or APD). The types and locations of structural BMPs for the typical well
pad configuration arc shown on Figures 2 and 3. Guidance for BMP selection is provided
on Figure 4. The general sequence of BMP installation and well pad construction
includes:
• V cgctation is grubbed, cul, and stockpiled on the downhill side,
• A run-on diversion channel is constructed for the pad,
• Earthwork is conducted to build the pad,
• Additional BMPs are installed according to site-specific plans which may include
additional snrface water diversion channels, sediment traps, and other temporary
sediment controls and interim BMl's.
4.1.1 Run-on controls
Jn order to divert surface nm-off from upgradicnt areas away from well pads, salvaged
topsoil or subsoil should be placed on the uphill side of the well pad cut slope. A soil
stockpile should be placed and graded to form a diversion berm that will direct surface
water away from the well pad. Alternatively, nm-on diversion berm/channel may be
constructed above the cut slope of the location. A typical benn/channcJ detail is given in
Appendix B,

South Parachute S WMP EnCana E&P
4. 1.2 Run-off controls
Run-off collection channel/bern1s or silt fence will be installed at the toe of well pad and
other fill slopes located within 100 feet of a surface drainage. Run-off controls may also
be needed in areas where steep slopes below the site will likely result in fast flow of
water from the location to nearby drainages. Typical benn/channcl and silt fence
installation details arc given in Appendix B.
4. 1.3 Well pad surface grading
In order to retain storm water on the well pad and to help contain incidental spills and
leaks, the well pad surface shonld be graded at 1 % to drain toward collection snmps
located on the fill-slope side of the pad. Well pads arc to be kept clean of any
contaminants (e.g., chemicals or hydrocarbons) such that the waters collected in these
sumps may be filtered of sediment and discharged off-site per the CDPS Final Permit
associated with that pad's SWMP. Waters collected in the sumps found to contain
chemicals of any kind will be collected and trucked to a proper disposal facility. Typical
well pad layouts arc shown on Figures 2 and 3.
4. 1.4 !fay bale check dams
Hay bale check dams or other adequate check dams will be installed in areas of
concentrated flow. A typicai' installation location is shown on the typical well pad layout
(Figures 2 and 3). !lay bales or other adeqiiatc check dams should also be installed at
suitable locations along new access roads. Wherever possible, hay bales will be replaced
with ftbcr-fillcd.wattlcs to increase longevity of this l3MP. Typical hay bale check dam
installation details arc given in Appendix 13.
4. 1.5 Rock check darns
Rock check darns or other adequate check dams will be installed in areas or concentrated
flow. Rock check dams may be used instead of hay bale check dams in areas where steep
slopes, high flows, or long-term exposure arc expected to result in failure or frequent
maintenance of a hay bale structure. Typical rock check dam installation details arc
given in Appendix B.
4. 1.6 Road drainage relief
Culverts, rolling dips or water bars may be used to provide road surfaces with drainage
relief. Road drainage relief spacing will vary depending on erodibility of local soils and
road slope. Guidance for road drainage relief is available in the BLM "Gold Book" and
Low-Volume Roads references listed in Section 4. 1.19. Depending on the location and
type of drainage relief installed, additional sediment control features may be needed such
as sediment removal at the inlet and erosion protection at the outlet. Culvert spacing
guidance from the BLM "Gold Book" is given in the following table.
10
South Parachute SWMP EnCana E&P
4.1.7 Culvert protection
Installation of culverts may be needed where access roads cross drainages or where
surface drainage relief is needed. Culvert inlet and/or outlet protection will be provided
as needed and will typically include rock protection. Rock protection will typically be 2-
to 4-inch diameter rock, 4 to 6 inches deep, with dimensions of about 4 feet wide by I 0
feet long.
The area of rock lining should be prepared by removing 6-to 8-inches of soil. The
shallow excavation should be filled with rock and the rock secured in-place by bucket
tamping or wheel-rolling. Rock-lined outlets, where used, should be imtallcd to promote
lateral spreading of water as it flows across the rock. Culverts within jurisdictional
drainages will be installed according to the requirements of the U.S. Army Corps of
Engineers 404 permit. Culverts installed within drainages should be aligned with the
existing drainage path. Culverts. for road drainage relief should be installed with a skew
angle of between 0 and 30 degrees (20 to 30 degrees is preferred) from perpendicular to
the road to minimize scour at the culvctt inlet.
4.1.8 Straw waddles/straw rolls
Straw rolls, intended to capture and keep sediment on the slopes, are becoming a more
popular alternative to silt fences. Straw rolls are useful to temporarily stabilize slopes by
reducing soil creep and sheet and rill erosion until pennancnt vegetation can be
established. Straw rolls have an average effective life of one to two years. Prior to
installation, the slope may need to be prepared with small trenches placed across the
slope on the contour. These trenches should be deep enough to accommodate half the
thickness of the roll and be approximately 10 to 25 feet apart, depending upon slope
conditions. The rolls should he installed perpendicular to water movement (i.e., parallel
to the slope contour), being placed from the bottom of the slope upgradicnt. The rolls
should lit Lightly against the soil, with no gaps between the soil and roll. Stakes (usually
wood), driven through the roll and soil, should have only I to 2 inches exposed above the
roll and shou Id be spaced every 4 feet.
11
South Parachute SWMP EnCana E&P
4.1.9 Vegetative filters
Vegetative filters may be either standing vegetation in disturbed or undisturbed areas
(e.g., that area flanking the disturbance), or vegetative mate1ial salvaged from clearing
operations (e.g., "slash"). When using vegetative filters, consideration should be given to
the area of disturbance that will contribute flow, distance to surface drainage, density of
vegetation, and effectiveness of vegetation in slowing run-off and removing sediment.
4.1.10 Slope drainage relief
Rolling dips or water bars may be used to slow water ilow and allow infiltration along a
wide conidor (such as a pipeline corridor) or to reduce the amount of water flowing on
the corridor by shedding it (the water) off into natural drainage. Slope drains may also be
used to convey collected run-off water down a disturbed slope. Guidance on the spacing
of slope drains is available in the Low-Volume Roads reference listed in Section 4.1.19.
Depending on the location and type of drainage relief installed, additional sediment
control features may be needed such as lining witb rolled product or placement of erosion
protection at the outlet.
4.1.l I Soil bem1s
Soil berms may be used as pad contairnnent, to divert drainage away from areas or
concern or to direct flow toward sediment control structures. Where used, soil berms
should be constructed, where possible, of soil with sufficient fines to minimize flow
through the berm. Berms shall be at least 18-inches tall and should be compacted in
place by wheel rolling with suitable rubber tired, heavy equipment. A typical soil berm
detail is given in Appendix B.
4. l.12 Rocky areas
In areas of the project, significant rock debris, even bedrock, is anticipated to be
encountered. Jn some areas, the depth to bedrock is expected to be relatively shallow.
Excavation in these areas will rcsull in rock fragment and pieces being exposed on the
ground surface. Detritus in this area is tyi)lcally erosion-resistant scdin1cntary sandstone,
siltstone and/or shale. Both cut and Jill slopes in rocky areas may result in a surface that
is similar to gravel surfacing (see below) and, depending on the extent of detritus, may
precluclc the use of dov,nstrcam sediment retention BMPs (such as bem1s or sill fence).
The person selecting BMPs should use experience and best judgment in detennining
where downstream BMPs may be required.
4.1. I 3 Gravel surfacing
Gravel surfacing may he used to cover soil in areas of"high traffic such as roads, facility
areas, and. the area near well heads. Gravel surfacing forms a layer that protects soil from
wind and water erosion and prevents vehicle tracking. Some gravel surfacing may
12
South Parachute SW!V!P EnCana E&P
constitute a portion of the 70% stabilization required to move into the final stabilization
phase.
4.1.14 Rolled products
Rolled products cover a broad variety of manufactured products that are supplied in
rolled packages and function as a protective layer for underlying soil. Rolled products
may include straw, aspen fibers, coconut fibers, or synthetic fibers. They may be single
or double-ncltcd or may have no external netting. Generally, the service life, durability,
and quality of product relate to their weight and cost. A single net, straw mat may suffice
for a moderate slope where successful revegetation is expected within 6 months or less; a
double net coconut fiber mat may be needed for steep slopes where revegetation is
expected within 24 months or less; and a synthetic fihcr turn reinforcement mat (TRM)
may be needed for indefinite channel linings. These products are available from a variety
of manufacturers.
Manufacturer's guidance and local experience should be considered before selecting a
rolled product to use in a specific application. Rolled products should be installed
according to the manufacturer's recommendations. Generally, the use of rolled products
should be considered for post-construction stabilization of areas that have steep slopes,
erosive soils, or may be expected to have concentrated flows.
4.1.15 Surface roughening
Soil slopes can be roughened by track-walking with bulldozer or other acceptable,
tracked equipment or by use of an equipment bucket. Roughening should be conducted
after slopes have been completed and p1ior lo seeding. Track-walking should be done by
a vehicle operating up and down the slope to create minor depressions that arc
perpendicular to the slope. These minor depressions lrap seed and collect water and
create a micro-climate that enhances vegetative success. This should be conducted in
areas that will be broadcast scedc.d. This technique for surl'acc roughening is given in
Appendix B.
4.1.16 Temporary seeding of pads in the construct1011 phase
\Veil pads may contain multiple wells. Given the estimated 1 year or more between pad
construction and stabilization grading and vegetation; temporary seeding of cut and fill
slopes and all disturbed areas that will not be used for work activities should be
considered. This temporary seeding will not only help reduce erosion but will help avert
the colonization and spread of i11vasivc and noxious weeds. Establishment of vegetation
on topsoil stockpiles is critical as this will help maintain viability of the topsoil resource.
Segregation of topsoil material and replacement of topsoil in its respective original
position (last out, first in) would assist in the rccstnblishment of soil health and
productivity.
13
South Parachute SWMP EnCana E&P
The temporary seed mix should include annual, cereal crop seeds such as oals or barley,
or sterile hybrid such as "Regreen" to establish vegetative cover and suitable grass
species. Grass seed will be included in the seed mix to provide sustainable vegetative
cover in the event that a well pad remains in the construction phase for longer than one
year. The temporary seed mix, rate, application method, and supplemental materials will
be determined by EnCana or the BLM as appropriate for the land ownership.
4.1. l 7 Pennanent seeding of pads in the post-constrnction phase
Wells pads are graded after drilling, completion, and facility installation to reduce the cut
and fill slopes and reduce the area of the pad surface. Seed mix application is done in the
next available seeding season.
The pcnnanent seed mix should include amrnal, cereal crop seeds or sterile grass species
(e.g. Regreen) to help establish vegetative cover. The pennanent seed mix, rate,
application method, and supplemental materials will be dctem1incd by EnCana or the
BLM as appropriate for the land ownership.
4.1.18 Seeding of other disturbed areas
Alier drilling of all wells and installation of associated production facilities (storage
tanks, meters, pipelines, etc.), the well pads will be partially reclaimed to reduce the cut
and fill slopes. The well pad will remain in this configuration for the useful and
economic life of the gas wclls--as much as 30 years or more. To best provide for long-
term vegetation of these well pads they should he vegetated llu-ough application of a
permanent seed mix.
The pennancnl seed mix, rate, application method, and supplemental materials will be
selected by EnCana or the BLM as appropiiate for the land ownership. To mininuze
weed colonization, certilied "weed free" seed mixture will be used. These areas will be
inspected to confinn vegetative growth, assess the need for reseeding, and assess the need
for weed control.
4.1. l 9 Additional mvIP references
The structural and non-structural BMPs listed above arc intended to include all Bi'vfl's
that may be used for EnC<ma's E&P projects. However, there may he situations where a
BMP is needed but not included above or project personnel may need additional
information on the use, specification, and maintenance of l3MPs. Additional infonnation
resources are listed below:
• For oil and gas operations, the Bureau of Land Management and U.S. Forest
Service have developed "Surface Operating Standards and Guidelines for Oil and
Gas Exploration and Development" (known as the "Gold Book"). The most
recent version of this is available on the internet at
http://www.blm.gov/bmpJ(_JoldBook Draft vi 2.pdl,'.
14
South Parachute SWMP EnCanaE&P
• For constrnction BMPs, the Urban Drainage and Flood Control District, a
Colorado front range group of city and county agencies, has developed a BMP
manual that is available on the internet at http://www.udfcd.org/usdc111/vQ.!~.l1tm
• For access roads, the US Forest Service and Bureau of Land Management have
developed "Low-Volume Roads Engineering, Best Management Practices Field
Guide," which is available on the internet at
http://www. b lm.gsi.,Y[bmp/fi e ld %2 Ogui de. htm
4.2 Stom1 Water Management Controls
As development of the property progresses, well pads, access roads, and facilities areas
will be planned and constructed. This SWMP is intended to provide:
I. Guidance for ston11 water management;
2. A list of suitable strnctural BMPs;
3. Guidance for rcvegetation,
4. Requirements for specification, installation, inspection and maintenance ofBMPs;
and
5. Requirements for inspection, documentation, and reporting of BMPs and
revegetation.
Given the number of individual facilities within the South Parachute Area and relatively
uncertain project schedule, site-specific BMP requirements will be developed as plans for
construction are finalized. These site-specific BMP plans will be developed and
submitted to the storm water administrator. Site-specific infonnation contained in
inspection logs and archives, although not bound with this document, arc considered to
he supplemental documents to this SWMP and will be maintained in accordance with
EnCana's Specifics of Administrative Operations (sec Appendix C). The storm water
administrator will:
1. Maintain the SWMP, site-specific infomiation, and permits;
2. Ensure that stonn water inspections are conducted as needed, that inspection
reports arc filed, and that necessary maintenance is conducted;
3. Ensure that rcc1an1ation grading and revcgctation arc conducted to standard and
that rcvcgctatcd areas arc inspected to dctcrrninc if vegetative success has been
achieved or if weed controls andior reseeding are needed;
4. Ensure that the South Parachute stonn water managemcnl program is conducted
in accordance with the storm water pcnnit.
Depending on the t:rve and location of new facilities there may he a need for inclusion of
new and different BMPs. In general, new developments should be planned with
consideration for storm water quality (e.g. minimize disturbed area and maximize
distance from drainages, as practicable).
Developments on the properly, primarily existing andior improved roads, not currently or
specifically addressed in the SWMP will be periodically checked for erosion and
drainage problems. This is especially important for disturbed areas located within I 00
15
South Parachute SWMP EnCana E&P
feet of surface drainages or creeks. If problems are noted, they should he reported to the
Site Manager and/or SWMP administrator. Problem areas may .be addressed through
surface grading, but will likely need to be addressed through installation ofBMPs.
4.3 Other Controls
4.3. l Waste management and disposal
Well pad constrnction and drilling will generate various other wastes during the course ol
construction. Other wastes may include the following:
• Trees and shrubs from clearing operations,
• Trash and debris from construction materials and workers,
• Drill cuttings,
• Drilling fluids, and
• Sanitary sewage.
Each of these wastes will be managed so as to not contribute to stmm water pollution.
Trees and shrnbs will be piled along the toe of well pad fill slopes to provide additional
sediment control. Construction trash and debris will be collected in containers and
hauled off-site for disposal in suitable landfills. Sanitary waste will be containerized in
portable toilets or other storage tanks with waste materials regularly pumped and
transported off-site for disposal at approved facilities. All drilling fluids will be
circulated within tanks or placed within the reserve pit. A minimum of two feet of
freeboard will be maintained at the reserve pit at all times to minimize the potential for
overflowing. Prior to pit closure all non-exempt materials and liquids which have been
placed in the pit may be hauled to another well site soon to be drilled or will be allowed
to dry before backfilling the pit. Alternatively, pit fluids may also be removed and
disposed of at a certified disposal facility.
4.3.2 :rvtatcri;:1ls n1anagcn1cnt
Petroleum Products
Petroleum products which may be present at the construction/drilling sites include:
gasoline, diesel foci, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and
diesel fuel will be stored in portable storage tanks with secondary containrncnt.
Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in 55-gallon or
smaller containers.
Pollutants from petroleum products used during coustnrction and drilling activities adhere
easily to soil patiicles 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.
Proposed soil erosion and sediment control practices will aid in retention of spills or
leaks. Use or secondary containment and drip pans will reduce the likclil10od of spills or
leaks contacting the ground. Proposed maintenance and safe storage practices will
16
South Parachute SWMP EnCana E&P
reduce the chance of petroleum products contaminating the drilling site. Oily wastes
such as oil-absorbent pit booms, 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 rrom equipment and vehicles. Routine daily
inspections will be conducted to identify leaks and initiate conective actions, if needed.
The following guidelines for storing petroleum products will be used.
• All product containers will be clearly labeled.
• Drnms will be kept off the ground within secondary contaimncnt and stored under
cover if needed.
• Fuel tanks will be stored within 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 clean up and containment materials (absorbent, shovels, etc.) will be easily
accessible. Spills will be cleaned in a timely manner and reported as required in
accordance with applicable regulations (i.c, COGCC, CDPHE, EPA or other
agency requirements).
• 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. Workers should be reminded about proper storage and
handling of materials during periodic subcontractor or safety meetings
Qth§L):;hcmicals Products Management
Additional materials will be used and stored on site for use in well drilling, construction,
and completion. These materials will be stored appropriately and managed to minimize
spills and leaks. Storage areas will be regularly inspected and any spills or leaks will be
cleaned up immediately.
Magnesium chloride solution or other chemical dust suppressants may be applied on
unpaved roads to reduce fugitive dust generation. Magnesium chloride solution is nsed in
the winter for roadway deicing and in the summer for dust suppression by county and
state government entities. The solution is typically delivered to the site by contractors in
DOT approved tanker trailers aml generally is quickly applied to the ro<id surface. On
rare occasions, depending on work site conditions, the tanker trailers may be staged along
the road until ready for application.
L!iydown and staging areas
The drilling contractor will maintain a laydown or staging area for equipment and
materials storage at each site. These areas will be maintained with good housekeeping
and will be inspected on a regular basis for spills, leaks, and potential contamination.
Excavations at the well pads not needed for completion and production operations will be
filled immediately upon release of the drilling rig from the location.
17
South Parachute SWMP EnCanaE&P
4.3.3 Construction Site Housekeeping
Well pad housekeeping will consist of neat and orderly storage of materials and
containerized fluids. Wastes will be temporaiily stored in sealed containers ai1d regularly
collected and disposed of at off-site, suitable facilities. If spills occur, prompt cleanup is
required to minimize any commingling of waste materials with storm water nm-off.
Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans
will be used dming routine fueling and maintenance to contain spills or leaks. Any waste
product from maintenance will be containeiized and transpmicd off site for disposal or
recycling. There will be no major equipment overhauls conducted on site. Equipment
will be transported off site for major overhauls.
Temporary and permanent roads will be installed and stabilized to minimize the transport
of sediment from the road surface by mobile equipment.
Cleanup of trash and discarded materials will be conducted at the end of each work day.
Cleanup will consist of patrolling the well pads, access areas, and other work areas to
pickup !rash, scrap steel, other discarded materials, and any contaminated soi I. These
materials will be disposed of appropriately.
18
South Parachute SWMP EnCana E&P
5.0 lNSPECTION AT\'D MAINTENANCE PROCEDURES
To meet requirements of the General 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 qualified person familiar with the SWMP and control measures will conduct the
inspections:
2. Inspections will cover these area of the construction site and access roads--
• Disturbed areas without stabilization,
• Mqtcrial storage areas,
• BMPs,
• Surface water diversions,
• Downgradient areas,
• Access roads, and
• Locations where vehicles enter or exit the site;
3. lnspections will occur at least once every 14 calendar days while a site is in the
"construction" or "active" phase, and at least every 30 days once a site completes
1he cnnstrnc.tinn phase nnd hefore i1 is final stahi!izerl (referred to as the "interim
reclamation phase");
4. Inspections will occur as needed after a significant precipitation or snow melt
cvcn1; field personnel (i.e., pumpers) will access any damages to storm water
BMPs and infonn the stonn water inspectors of needed repairs; storm water
inspectors will visit those sites which are repo1icd as needing repairs, then
coordinate the activities of contractors in order to remain in compliance with the
Pcrn1it;
5. /\ Jog of inspections will he kept;
(j. Disturbed areas and material storage areas that arc exposed lo precipitation will be
inspected for evidence of pollutants leaving the disturbed acreage;
7. Sediment control BMPs will be inspected for evidence of deterioration, undcr-
eutting, and bnild up of sediment. Sediment will he removed when it has built up
O!lc-hall' to two-thirds the height of a sediment trap or one-third to one-half the
height of any other sediment retention structure (e.g., silt fences or wattles).
8. Public roads used for vehicle access will be inspected for evidence of off-site
sediment transport;
9. When B1vIPs or other site details discussed in the SWMP are modified, the
SWMP will he modified to accurately reflect the actual field conditions (e.g.,
removal of 8MPs, addition of !3MPs, modification of BMP design specifications,
and changes in items mcluded in the site map and/or description);
l 0. An inspection report summmizing the scope of the inspection, the name of the
person conducting the inspection, date of inspection, and observations relating to
the implementation will be prepared. Inspection reports will be retained for at
least 3 years from the elate that the site is finally stabilized;
19
South Parachute SWMP EnCana E&P
11. Actions taken to modify any storm water control measure will be recorded and
maintained with the S\VMP;
12. If no deficiencies are found drning the inspection, the report will contain
cettification that the site is in compliance with the SWMP. Signatures will be in
accordance with the General Permit Conditions, Part E. I (Appendix A).
Maintenance will include prompt repairs and/or adjustments to any erosion and sediment
control structures that arc deteriorating or found to be performing inadequately. Repairs
should be made as soon as possible and prior to the next anticipated stonn event, and no
longer than 7 days from the time of discovery of needed repairs (per the Pe1mit
requirements) unless an L;pset Notification is submitted to the CDPHE-WQCD.

South Parachute S WMP EnCana E&P
6.0 NON-STORMW ATER DISCHARGES
No non-stom1 water discharges are anticipated from the project. Possible exceptions
include fire prevention/suppression or dust control activities.
21
South Parachute SWMP EnCana E&P
7.0 FINAL STABILIZATION
Areas which have been disturbed arc considered to be finally stabilized when the surface
has either been built on, paved or graveled, and/or 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 methods have been employed. Re-
seeding alone does not qualify. Sites are considered final stabilized when the above
criteria have been met following construction activities and interim reclamalio1.1 (even
though the site will be disturbed in the future for final reclamation). However, future
land disturbances that follow final stabilization and result in disturbance of one acre or
greater would again require pennit coverage at that time.
Areas developed as stabilized unpaved surfaces as needed for operation of the facility
after interim reclamation, are also considered final stabilized. This essentially means dirt
road surfaces and the portions of the well pad surfaces that cannot be rcvcgctated due lo
operational necessity, and docs not include slopes, ditches, and other areas where
revegctation is necessary. Stabilized unpaved surfaces shall be prepared in such a way as
to prevent ongoing erosion issues.
Evaluation of stabilized, unpaved surfaces for access roads and interim phase well pad
surfaces will be on a case-by-case basis with consideration of soils, traffic levels, and
moisture conditions. Some access road and well pad surfaces may be effectively
stabilized by proper ~'rading of native materials and others may need gravel surfacing in
order lo prevent ongoing erosion issues.

2.6 Spill Prediction and Control (40 CFR 112.7 (a) and (b))
Equipment located at the subject facilities with the potential to accidentally release oil are
specifically addre5sed by location in Appendix F.
The reasonably expected modes of major failure or accident for which oil could be released from the
facilities arc as follows:
A. Bulk Storage Tank Leak or Failure
I. Failure Modes: Cotrnsion, vandalism, lightening strikes, valve or piping
failure, overfilling.
ll. Rate of Flow: Variable, depending upon the type, size and location of the
tank failure. The ambient temperature at the time of the release may effect
the viscosity of the oil and thereby impact the rate of flow. Flow rates for
corrosion failure are typically low, ranging from less than a gallon per day to
a gallon per hour. Flows resulting from valve and piping failures or
vandalism typically range from a gallon per hour to 400 bbls per hour.
Lightning strikes may result in a release that is essentially instantaneous.
III. Discharge Quantity: Variable depending upon the type and 1ocati0n of the
failure. The total quantity discharged would not exceed the working capacity
of the largest tank.
IV. Preventative Measures: Storage tanks areconstrnctcd in accordance with A Pl
industry standards. Materials used in constructing the tanks are co1npatible
with the substances stored. Where practicable, earthen bcnns or other
diversionary structures arc utilized lo control any released fluids. Tanks arc
appropriately sized to minimize the risk of overfilling.
B. Tanker Truck Loading and Unloading Operations
I. Failure Modes: Piping or valve failure, tank failure, overflow, and human
error.
11. Rate of Flow: Variable depending upon the type, size and exact location of
the failure, and the amount of oil in the tanker trnck and storage tank. The
ambient temperature at the time of the release may effect the viscosity of the
oil and thereby impact the rate of flow. Flow rates resulting from piping and
valve failures can range from I gallon per hour up to 400 bbls per hour. The
flow rate for tank ttuck overflows typically will not exceed 5 to I 0 bbls per
minute. Tank failures may result in releases that are essentially
instantaneous.
South Rockies Parachute Arca
FnCana Oil & Gas (USA) Inc.
16
SPCC Plan
May 6, 2005
Ill. Discharge Quantity: Variable depending upon the type and location of the
failure. The total quantity discharged would not exceed the working capacity
of the largest tank.
IV. Preventative Measures: Tanker truck loading and unloading operations me
conducted in accordance with United States Department of Transportation
regulations (49 CFR 177). All loading operations arc attended by the truck
driver. No smoking or open flames are allowed in the vicinity of the storage
tanks and loading area. Wheel chocks arc placed at the wheel nearest the
truck loading connection to reduce the risk of the truck movement during
loading operations. Following the completion of loading operations, the
transfer line is disconnected and all valves and outlets on the tanker truck and
the storage tank arc visually inspected for leakage p1ior to vehicle depal1\1re.
C. Process Unit Failure (Separator/Heater Treater/Gun Bancl)
J. failure Modes: Process vessels may potentially rupture, or associated Jines,
valves and gauges may fail or leak.
II. Rate of Flow: Variable, depending upon the mode and extent of the failure.
The maximum expected rate of flow from a process unit failure is the oil
production rate of the well plus any additional fluid volume contained in the
vessel above the elevation of the rupture. The oil production rates for the
suhject prope1tics are contained in Appendix F.
lfI. Discharge Quantity: Variable, depending on the type of failure and the length
of time that the failure went undetected.
VI. Preventative Measures: Process units are constructed in accordance with AP!
and ASME indusliy stalldards. Where practicable, earthen berms or other
diversionary structures are utilized to control any released fluids.
D. Piping Failure
I. Failure Modes: Doth aboveground and buried pipelines may rupture or
corrode and leak. Associated flanges, scrc,vcd connections, valve~ and
gauges are also subject to corrosion and may fail or leak.
II. Rate of Flow: Vaiiable, depending on the size and location of the piping
related failure. The maximum potential rate offlow is not expected to exceed
the oil production rate as listed in Appendix F.
II!. Discharge Quantity: Vmiable depending upon the type and extent of the
failure and the length of time that the failure went undetected.

May 6. 2005
IV. Prevention Measures: Personnel routinely perform visual inspections of
aboveground piping and buried flow line right-of-ways to detect failures. As
warranted by soil conditions, co1rnsion protection is provided for buried
pipelines.
2.7 Impracticable Containment or Diversion Measures (40 Cli'R 112.7 (d))
In some instances, contaimncnt, diversionary structures, or equipment to prevent oil from reaching
navigable waters maynol be practicable. Secondary containment is provided for equipment located
at the subject facilities as indicated in Appendix F.
Secondary contain1nenl or divcrsio11a1y structures n1ay be iinpracticable for son1c cquipn1enl at these
facilities for the following reasons:
Extensive diking and/or drainage trenches would interfere with site access for nonnal
operations and also \.vith current surface land use.
An cflective dike system would be difficult to design and to construct. Damage to vegetation
and potential erosion due to construction of dikes would probably be worse than the risk
adjusted environmental impact of a spill. lt would also be difficult to maintain dike integrity
and to drain off rain water.
f'lowlincs operate at pressures far below the rated working pressure and therefore have a
n1ini1nal risk of rupture.
Bcn11s, trenches and other n1eans of containrncnt can. trap explosive gases such a:-> 111clhauc
and hazardous vapors such as hydrogen sulfide leading to potential safety and exposure
problems.
The bcnns or diversions would trap storm water and cause muddy conditions which in turn
can create slippery unsafe working conditions. Trapped water may also increase the rate of
corrosion.
Cellars on \vcllheads arc not used because they can contain \Vater \Vhich rnay cause corrosive
cor1ditic.ns or trap hazardous ga;cs causing explosive or human health hr.:r:urd:;.

In the event of an accidental release, EnCana Oil & Gas (USA) Inc. personnel will promptly initiate
recovery actions as appropriate.
Levels of Response
Major Releases: Major releases arc defined as:
I) Spills of crude oil, condensate, or saltwater greater than I 0 bbls, or
2) Spills of refined crude oil products, including hut not limited to,
gasoline, diesel fuel, aviation fuel, asphalt) road oil, kerosene, fuel oil,
and derivative of mineral, animal or vegetable oils, or 3) Any volume
of oil which results in a fire, will reach a waler course, or may with
reasonable probability endanger public health or result in substantial
damage to property or the environn1ent.
Major releases will be handled under the direction of EnCana Oil &
Gas (USA) Inc. personnel. Response contractors listed in Appendix
A will be utilized as necessary to complete the clean up. If oil should
tiu·catcn surface \Vatcrs) the co1npany contingency plan \vill be
implemented. Containment strnctures would be constructed and
booms would be deployed as needed to protect waterways.
Minor Releases: Releases not classified as major shall be reported internally to the
appropriate supervisor on an incident report.

Product Recovery and Handling
Spills onto Soil
Mobile oil spills should be contained as soon as possible by the construction of earthen clams or by
the placement of mechanical baITicrs. Free oil may be removed from the ground by the use of a
vacuum truck. Sumps or trenches may be dug to intercept or drain free oil. Remaining free oil may
be removed from the ground by the use of oil-absorbent materials.
When all free oil has been removed, the affected soil containing over 1.0% total petroleum
hydrocarbon (TPH) by weight should be delineated, hoth ve1iically and horizontally. All soil
containing over 1.0% TPH should then be excavated by backhoe or similar appropriate equipment
fi.>r retncdialiun or-disposal.
To prevent stormwater contamination, all impacted soils containing in excess of 1.0% TPll should
placed in an approved disposal site or in a secure interim storage location for future remediation or
disposal, unless more immediate on-site techniques and be implemented. Placing the impacted soil
on a sheet of visquene and providing appropriate cover, diking, or stormwater diversions, is
acceptable.
A final cleanup level of 1.0% Tl'H should be achieved as soon as practicable. Several methods are
acceptable for the cleanup of oil contatninated soil; regulatory agencies n1ay specify \vhich 1neihods
arc appropriate.
Spills onto \Vater
Oil spills onto surface waters must be cleanse up to the satisfaction of the landowners and regulatory
agencies. The spill should be contained as soon as possible by the use of floating booms or other
mechanical harriers. Free oil may be removed from the water by the usc of a vacuum truck or by oil-
skimming equipment. Remaining free oil may be removed from the water by the usc of oil-
absorhcnt materials such as spray-sorb. Oil-absorbent materials may also be used to remove oil that
has accun1ulatcd on shoreline soils, rocks and vegetation. Oil contan1inatc<l shoreline rnatcrials may
require removal to a suitable treatment site for cleanup as described above.

STORMWATER INSPECTION PROCEDURE
AND DRAINAGE RECORD
STORMWATER INSPECTION PROCEDURE AND DRAINAGE RECORD
Eatthcn benns, containment rings, and other containment structures arc inspected on a regular basis
for accumulations of oil and precipitation. These inspections are not typically documented.
Generally, drainage from containment structures is not conducted. Minor accumulations of
precipitation are allowed to evaporate. Large accumulations of fluids may be removed by vacuum
truck and either returned to a separation vessel for processing or transported to a permitted
recovery/disposal facility.
In the unlikely event that drainage events arc conducted, the accumulated ston11water is visually
inspected for contamination from oil. NO oil is released from or pumped from within the berm onto
the ground or into a water course. Drainage or pumping does not occur until the fluids have been
inspected for oil. Draining only occurs with constant visual supervision of the drain outlet, and only
after dete1111ining that the water is indeed fresh. Draining ceases at the first sign of an oil sheen and
the remaining, ilnid is removed and properly treated or disposed. The foreman in charge of the
facility operations is consulted before any berm is drained or purged.
As required by law, any time that stomnvater is discharged from the dike, a record of the inspection.
discharge and oil removal is to he maintained. The following is the discharge record:

Introduction
T he plan is for conformance with Garfield County Regulation 9.07.04 ( 13) (BOCC 2006). The
EnCana Oil & Gas (USA) Inc . (EnCana) Well Pad PN 30 Communications Tower site is located
in NE Y4 SE Y4 Section 30, T7S, R95W, 6rn Principal Meridian (Map; Figure I, page 10) o n Hi g h
Mesa. The s it e overlooks Parachute Creek vall ey to the north and much of EnCana's operations
area as can be seen in Photo 2, below, with Mt Callahan to the left.

On June 14 , 2007, a field in spec ti o n was conducted by WestWater Eng ine e rin g (WWE)
biologists. The inspection identified appropriate topics for inclusio n in an integrated vegetation
and noxious weed management plan. Factors considered include soi l typ e a nd texture, exist ing
land m anageme nt, a bsence or presence of li sted noxious weeds, a nd potential natural vegetation
community.

Landscape Setting
Well Pad PN 30 is o n the third terrace above the Colorado River near the highline of the rid ge
forming the no rtherly side of Dry Creek. Slopes are steep and erosive. Soil is Potts-Ildefonso
complex, a fine, sandy loam found on mesas, alluvial fans, and the s ides of valleys at elevations
ranging from 5,000 to 6,500 feet and on slopes of 12 to 25%. Parent material for this soil
complex consists of sandstone, s hale, and basalt (NRCS 1999). Thi s so il complex is deep, well
drained and has medium surface runoff and moderate erosion hazard. lmmediately north of the
site, slope le ssens , soils become deeper and vegetation changes from pifion pine-Utah juniper
woodlands (Pinus edulis-Juniperus utahensis) to sagebrush-wheatgrass meadows (Artemesia
tridentata spp-Pascopyrum smithii) as can be seen in Photos 3 and 4.
Photo 3. Cattle loafing under juniper Photo 4. Sagebrush-grass meadow north of site
Dominant o r major species of characteristic natural vegetation expected at thi s s ite with these
soi l conditions includes western wheatgrass (Pascopyrum smithii), needle a nd thread
(Hersp erostipa comata comata), bluebunch wheatgrass (Pseudoroegneria spicatum spicatum),
big sage bru sh (Artemesia tridenatata s pp.), indian ricegrass (Achnatherum hymenoides),
bottlebru sh sq uirreltail (Sitanion hys trix), and Truckee rabbitbrush (Chtysothamnus viscidifloris)
(NRCS 2007a).
Amount oflnfested Land Needing Treatment
There were no li s ted noxious weeds on the communications tower site as of June 2007. Two
li s ted noxiou s weed species, mu sk thistle and houndstongue, were found near, but not on, the
site. Both numbered les s tha n I 0 plants each and were located within the disturbed road ri g ht-of-
way. Garfield County li sted no xious weeds with high potential for thi s s ite are s hown in Table I.

The strategies summarized in Table 2 for annuals and biennials, and in Table 3 for perennials are
those found to be most effective depending on the growth habits of each species, i.e., annual,
biennial, or perennial. This information is contained herein to emphasize the importance of
knowing the species of weeds present.
Table 2. Treatment Strategies for Annual and Biennial Noxious Weeds
Target: Prevent Seed Production
1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds
develop, cut and bag seed heads.
2. Chop roots with a spade below soil level.
3. Treat with herbicide in rosette or bolting stage, before flowering.
4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but
can reduce total seed production.
Table 3. Treatment Strategies for Perennials
Target: Deplete nutrient reserves in root system, prevent seed production
I. Allow plants to expend as much energy from root system as possible. Do not treat when first
emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible.
2. Herbicide treatment at bud to bloom stage or in the fall (recommended after August 15 when natural
precipitation is present). In the fall plants draw nutrients into the roots for winter Treatment.
Herbicides will be drawn down to the roots more efficiently at this time due to translocation of
nutrients to roots rather than leaves. If the weed patch has been present for a long period of time,
another season of seed production is not as important as getting the herbicide into the root system.
Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on
the roots at this time.
Westwater Engineering Page 3 of 9 pages 7/8/2007
Well Pad PN30 Communications Tower
Table 3. Treatment Strategies for Perennials
Target: Deplete nutrient reserves in root system, prevent seed production
3. Mowing usually is not recommended because the plants will flower anyway. Seed production should
be reduced. Many studies have shown that mowing perennials and spraying the re-growth is not as
effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is
imperative to know the species and its basic biology. Timing of application must be done when
biologically appropriate, which is not necessarily convenient.
4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only l/2" -I" long.
Clean machinery thoroughly before leaving the weed patch.
5. Hand pulling is generally not recommended for perennial species unless it is known the plants are
seedlings and not established plants. Hand pulling can be effective on small patches but is very labor
intensive because it must be done repeatedly.
Recommendations
Total, non-selective, vegetation control by soil sterilant is recommended within the perimeter
fence of the facility. Newer soil sterilant herbicides such as DuPont Sahara® are formulated to
reduce migration and leaching into non-target areas and require very low amounts of an active
ingredient, which decreases probability of bio-accumulation in non-target species. Temporary
disturbance is recommended to be re-seeded with the seed mix below in early to late fall. Re-
seeded areas should be rested from domestic livestock grazing for 2-3 years until establishment.
The seed mix is for permanent reclamation of the site.
Best Management Practices
The following practices should be adopted for construction projects within the natural gas
development area to reduce the costs of noxious weed control. The practices include:
•
•
•
•
•
•
•
top soil, where present, should be segregated from deeper soils and replaced as top soil
on the final grade,
top soil stockpiles should be seeded with non-invasive graminoids if stored longer than
one growing season,
in all cases temporary disturbance should be kept to an absolute minimum,
equipment brought to the site should be cleaned of soils remaining from previous
construction sites which may be contaminated with noxious weeds,
equipment and materials handling should be done on established sites,
if working in contaminated sites , equipment should be cleaned of potentially seed-
bearing vegetative debris,
temporary disturbances should be immediately replanted with the recommended mix in
the re-vegetation section.
In areas with slope greater than 3% slope, imprinting of the seed bed is recommended.
Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope.
When hydro-seeding or mulching, imprinting should be done prior to seeding unless the mulch is
to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be
done as part of the harrowing. Furrowing can be done by several methods, the most simple of
which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple
imprinting methods include deep hand raking and harrowing, always perpendicular to the
direction of slope.
Westwater Engineering Page 4 of 9 pages 7/8/2007
Well Pad PN30 Communications Tower
Herbicides
Spot treating with both selective and non-selective herbicides may become necessary and should
include areas immediately adjacent to the site on adjoining lands.
Chemicals typically used include synthetic auxin growth regulators (e.g., 2,4D; Tordon, Banvel,
and Garlon, all selective), EPSP synthase inhibitors (e.g., glyphosate, a non-selective) or a mix of
these. In all cases, the applicator shall deem which chemical(s) and at what concentration(s)
shall be used at the time of application. The applicator alone is responsible for following
application rates specified in the label for the chemical selected. It is anticipated the
aforementioned classes of chemicals will be first choice of most Certified Applicators or
Qualified Supervisors.
It is recommended a private, licensed contractor be engaged to conduct the weed control and
monitoring, or that a company representative with weed identification capabilities and pesticide
application knowledge (preferably with a certified applicator's license) be assigned this function.
Grazing
To encourage re-establishment of desirable vegetation, removal or significant reduction of
domestic livestock grazing is recommended for areas surrounding the facility until perennial
vegetation is established in desired areas.
Mechanical
Both musk thistle and houndstongue can be successfully controlled by mechanical removal in the
rosette stage (Sullivan 2004). Flowering plants can be mechanically removed but timing is
critical. It should be prior to seed drop but too late in the growing season for the plant to re-
flower. It is recommended company field employees be trained to recognize these plants and
carry a shovel to remove small infestations of a few plants as noted on the access road to the
Communications Tower site.
Alternative Methods
For this site an alternative method particularly useful for cheatgrass infestations and poor to non-
existent topsoil is the application ofvesicular-arbuscular mycorrhizal fungi (V/AMF). These
fungi, mostly of the genus Glomus, are symbiotic with about 80% of all vegetation. In
symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as
much as several orders of magnitude (Barrow and Mccaslin 1995).
Over-the-counter VI AMF or AMF commercial products, which are better adapted to coating
seeds when re-seeding and treating roots of live seedling trees and shrubs at time of planting,
come in powder form and are available from many different sources.
Other alternative methods such as beneficial insects are not practical for this site due to the low
incidence of infestation of target species such as musk thistle.

Re-vegetation
Soil types in the area generally support many of the same species of native vegetation.
The seed mix shown in Table 4 is adaptable to this site. The mix includes five species of native
grasses known to be available commercially at reasonable costs.

Seeding rate should be doubled for broadcast application. Preferred seeding method is hydro-
seeding or multiple seed bin rangeland drill with no soil preparation other than simple grading to
slope and waterbars. Seed should be bagged separately so each size group of seed can be
metered at the appropriate rate.
Alternative seeding methods include but are not limited to:
• harrow with just enough soil moisture to create a rough surface, broadcast seed and re-
harrow, preferably at a 90 degree angle to the first harrow,
• hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking.
• These are not the onlr, means of replanting. However, these methods have been observed
to be effective in similar landscapes.

Landscape Setting
Well Pad PN30 is on the third terrace above the Colorado River on High Mesa, a cuesta forming
the northerly side of Dry Creek. Slopes are steep and erosive south and ge ntly run to the nor th .
Soil is Potts-Ildefonso complex a fine, sa ndy loam fo und on mesas, alluvial fans, and the sides of
valleys at elevations ran g ing from 5,000 to 6,500 feet and on slopes of 12 to 25%. Parent
material for this so il complex consists of sa nd sto ne, shale, and basa lt (NRCS 1999). This so il
complex is deep, well drained , and ha s medium surface runoff and moderate erosion ha zard .
Uses for thi s soil complex include limited grazing and wildlife hab itat. Immediately north of the
site, s lope le ssens, so ils becom e deeper and vegetation changes from pinyon pine-Utah juniper
woodland s (Pinus edulis-Juniperus utahensis) to sagebrush-wheatgrass mead ows (Artemesia
tridentata spp-Pascopyrum smithii) as can be seen in Photos 3 and 4.
Photo 3. Cattle loafing under juniper
Dominant or maj or spec ie s of characteristic, natural vegetation expected at thi s site with these
soil conditions includes western wheatgrass (Pascopyrum smithii), ne ed le and thread
(Hersperostipa comata co ma/a), bluebunch wheatgrass (Ps e udoroegneria spicatum spicatum),
big sageb ru sh (Artemesia tridenatata spp.), Indian ricegrass (Achnatherum hymenoides),
bottlebru sh squirreltail (Sitanion hystrix), and Truckee rabbitbrush (Chtysothamnus viscidijloris)
(NRCS 2007a).
Site Inspection and Survey
A s ite inspection by WWE occurred durin g a period of hot, dry weather on June 13, 2007. The
perimeter and adjoining land s were surveyed for plant communities, li sted no xious weeds, soil s
and wildlife and their sign.
The table below presents a list of wildlife species which could be expected to be observed on or
from the site prior to the indu st rial development all read y present. The data , obtained from the
Colorado Division of Wildlife , County Species Occurrence database, was extracted and modified
by WWE biologists bas ed on the plant communities present on and adjoining the site a nd
potential wildlife us ing tho se communities not only at th e time of year of the survey but for
complete annual cycle.

Discussion
The site is within a relatively young, even-aged stand of Utah juniper dominated woodlands as
can be seen in the Photo 2. A few older trees were spared from fire that created the even-aged
condition of the stand. The older trees in particular are valuable to avifauna within the area
affected. These types of woodlands provide escape and winter night cover for mule deer due to
tree shape, size and location on the edge of the steep slope of a cuesta. Considerable past winter
use by mule deer was evident. The woodlands also provide food, cover, nesting or shelter
habitat for many of the other above listed species not specifically mentioned.
Within the overall landscape this site is ofrelatively low value to many wildlife species listed.
Some species listed wander through or pass over the site. Grazing by mule deer or elk on
perimeter vegetation is possible during periods of low activity in the immediate vicinity.
Wildlife use observed includes evidence of winter use by mule deer.
Grazing by cattle was evident at the time of inspection (Photo 3). Cattle were observed nearby
grazing on reclamation grasses not yet fully developed.
Similar habitat to that which has been developed is fairly common locally (immediate vicinity of
project site). Although many well pads and small and large ranches are mixed throughout the
local landscape, wild! ife continues to be generally abundant in the local area. During times of
peak human activity wildlife will be displaced from the immediate vicinity. Upon completion of
intensive development work, displaced wildlife should freely return to the area during the
operation phase.
Wildlife Mitigation and Management Recommendations
Improve woodlands and sagebrush shrublands. Greater than 95% of the site is developed and
it is a relatively small site compared to the surrounding landscape. Some methods to compensate
for the loss of wildlife habitat from development of the site would be to improve nearby
unaffected sagebrush plant communities and open up woodland canopy. Methods including
mechanical removal of invasive pinyon pine or Utah juniper, chopping or mowing a portion of
the older, more senescent sagebrush, and removing all or a portion of domestic livestock grazing
could be implemented. Mechanical removal of invasive woodlands into sagebrush plant
communities can have a positive impact for many years.
Minimize footprint of temporary disturbance. Reduce to the minimum level possible all soil
disturbing activities. Park construction vehicles on previously disturbed lands during
construction to further reduce temporary disturbance.
Re-seeding. Temporary disturbances on site have been recommended to be re-seeded with
native grasses and shrubs as well as introduced with, short-lived but highly wildlife-desirable,
non-bloating legumes. There is not enough space to be re-seeded in order to affect wildlife use.
However, reducing the potential for noxious weeds is a positive measure for wildlife. These
measures are described in the Integrated Vegetation and Noxious Weed Management Plan for
this site.
WestWater Engineering Page 5 of7 pages 7/8/2007
Well Pad PN30 Communications Tower -Wildlife
Fence Maintenance. The perimeter fence should be maintained in a way that reduces the
potential for mule deer entrapment and entanglement in the fence. It is recommended that any
unnecessary fence be removed to reduce potential wildlife entrapment in severe winters.
Resting reclamation grasses. U. S. Department of Agriculture, Natural Resource Conservation
Service Plant Guides and Plant Fact Sheets for individual species of graminoids useful in
reclamation in the west, recommend deferring grazing for a period of 2-3 years until the plant is
established (NRCS 2007b ). Active grazing on recent reclamation risks invasive species.

Project Emergency Response Specifics.
Emergency Response is made up of two elements: 1) a response to the emergency and 2)
a notification to acquire the necessary support. These two clements are typically
described in company specific emergency response plans and are designed to effectively
provide life safety, protect property, minimize risk to the environment, and mitigate
impacts on corporate image and reputation.
This summary covers the expectations, protocols, roles and responsibilities to support the
Emergency Response Plans for EnCana owned properties including pipeline construction.
First and foremost is life safely should an incident occur and is the responsibility of the
on site inspector, supervisor, and or senior hand lo make the appropriate calls
immediately per the list below to assist lhc ii~ured parties. (This list is based on the
closest ''"PllllSC times) Dini 911.
The next step is to infonn the EnCana representative above if not available refer to
Emergency Notification Charts supplied until someone is contacted. Once EnCana has
been contacted the company emergency response plan as well as the incident
management system will be initiated and the company trained persons will respond.
Understand that each incident is different and is assessed individually as to the mitigation
steps to be taken by those who arc involved. It is EnCana's responsibility to ensure
competent trained persons are responding.
ERP Quick Reference Guide supplies immediate persons involved as to how to assess the
situation until the appropriate EnCana response individuals arrive at the scene. It is
EnCana's responsibility to mitigate all incidents on our properties and make the
appropriate notifications.
This memo along witb the EnCana Notification Chart and the ERP Quick Reference
Guide will be placed in all vehicles associated to the conslruclion of the said
project/projects for EnCana in Garfield County.
