11. Project Facilities. Identify any permanent project facilities such as permanent right-of-
way, widths, meter stations, compressor stations, valve sets, etc. Also indicate any
temporary right-of-way, staging areas, width during construction, construction facilities,
etc.
Garfield County will no longer allow CDP 's (a metering, compression facility) to be permitted with
Pipeline Development Plans.
Aboveground facilities include vessels, block valves, side block valves, launcher/receivers and
cathodic protection devices. After completion of reclamation activities, aboveground pipeline
markers will be installed over the center of each pipeline.
The construction right-of-way will normally consist of a maximum of 120 feet of work area for the
construction of the pipelines and after the completion of the project; the right-of-way will revert
back to a 60 foot permanent easement for operation of the pipelines.
The proposed Staging Area location will require a graded pad of 2. 7 acres. An additional· extra
work space 50 feet wide by 1000 feet long will be graded if the J25 CDP to M30 tie-in bore is
chosen.
12.Construction Schedule. Indicate the estimated start and end dates for constructioR,
days of the week in which construction will occur, hours of day during which
construction will occur.
Construction activities are tentatively scheduled for March 2010 and will continue into the fall of
2011 or as weather and drilling operations allow. Working hours will normally range from 7:00
AM to 5:00 PM Monday through Saturday.
Construction activities will take approximately 24 to 32 weeks and will begin upon approval from
the Garfield County Planning Director. The duration of construction may vary depending on
drilling operations.
13. Sensitive Area Survey: List the types and areas of concern within and adjacent to the
pipeline right-of-way, such as: sensitive plant populations; identified cultural,
archeological and paleontological resources; and wetlands identified during pre-
construction environmental surveys. This rule does not apply in previously disturbed
corridors or rights-of-way and/or areas permitted by the Colorado Oil and Gas
Conservation Commission.
Sensitive Area Surveys have been completed for theproject area, The ELM is abo conductingan
Environmental Assessment. There are no identified archaeological, paleontological, wetlands or
sensitiveplant resources within the project area. The reports generated from the surveys are
included in Attachment 4.
14. Revegetation Plan.
1. Submit a plant material list. Be specific, scientific and common names are
required. Include application rate in terms of pure live seed (PLS) per acre.
2. Submit a planting schedule that includes timing, methods, and mulching.
3. Provide a revegetation security. A security may be required if, in the
determination of the County Vegetation Management, the proposed project has:
a) A potential to facilitate the spread of noxious weeds
b) A potential to impact watershed areas.
c) A potential for visual impacts from public viewing corridors.
d) Steep slopes (15% or greater) or unstable areas.
e) Disturbs large area (Half an acre or greater)
4. The revegetation security will be in an amount to be determined by the County
Vegetation Management that will be site-specific and based on the amount of
disturbance. The security shall be held by Garfield County until vegetation has
been successfully reestablished, or for a period of time approved by the County
Vegetation Management in any specific land use action, according to the
Reclamation & Revegetation Standards ·Section in the Garfield County Weed
Management Plan. The County Vegetation Management will evaluate the
reclamation and revegetation prior to the release of the security.
EnCana contracted West Water Engineering to develop a comprehensive Integrated Vegetation
Management Plan for Reclamation and Noxious Weed Control. This plan makes recommendations
for seed mixes, planting schedules as well as recommendations for controlling noxious weeds.
EnCana uses this plan for managing its operation on the North Parachute Ranch.
Seeding and reclamation activities will begin after final clean-up activities have been completed on
each portion of the project or during the next seeding window in the spring or/all. Disturbed areas
will be reseeded with the NP R Upper Zone Seed Mix. EnCana will only use seed that is certified
weed.free. Seed bag tags will be collected and submitted to the Garfield County Vegetation
Manager. Seeding rate will be listed as pounds per acre of pure live seed (P LS).

The right-o.fway will be scarified, tilled, harrowed, or roughened to a depth of 3 to 4 inches prior
to seeding, where needed, to prepare the seedbed and improve revegetation potential. Seed will be
placed in direct contact with the soil at an average depth of 0.5-inches, covered with soil, and
firmed to eliminate air pockets around the seeds. Seed will be applied using a rangeland seed drill
with a seed release and agitation mechanism siif.ficient to allow seeds of various sizes and densities
to be planted at the proper seeding depth. Broadcast seeding will be employed only in areas where
drill seeding is unsafe or physically impossible. Broadcast application rates will be double the drill
rate. Immediately after broadcasting, the seed will be uniformly raked, chained, or dragged to
incorporate seed to a sufficient seeding depth.
Upon completion of seeding activities timber slash and larger shrubs that were previously cleared
from the work area will be scattered along the reclaimed right-o.fway to aid in soil stabilization
and to minimize OHV traffic.
The NP R Reclamation Plan is provided in Attachment 5. The NP R Reclamation Plan describes in
greater detail the restoration guide for disturbed lands on the NP R from the result of constructing
well pads, roads, and pipelines.
A revegetation security will be provided to Garfield County once an amount for the security is
determined.
15. Weed Management Plan. A weed management plan for all Garfield County listed
noxious weeds and State of Colorado listed noxious weeds that are targeted by the
Commissioner of Agriculture for statewide eradication.
EnCana has an Integrated Vegetation Management Plan for noxious weed control and reclamation
which was prepared by West Water in 2009. EnCana will follow this plan and recammendations by
West Water to control the spread of noxious weeds. This Plan is included in Attachment 5. The
following measures identifY how EnCana will use Best Management Practices to control and
reduce the ~pread of noxious weeds:
• Ensure that equipment used on the project is clean and free of noxious weeds before arriving at
the project. Cleaning will be completed using either high-pressure water or compressed air to
remove potential weed seeds.
• Minimize soil disturbance to reduce areas of potential noxious weeds. Equipment and project
vehicles will be confined to the flagged project right-o.fway to minimize excess soil distur&ance.
• Salvage and segregate topsoil, then redistribute to reclaim the right-o.fway.
• Disturbances will be kept to a minimum.
• Establish native grasses and /orbs. The NPR Reclamation Plan included in Allachment &·has
identified the appropriate seed mixes for reclamation of disturbed areas.
• Eradicate weed introductions early through the uses of herbicides. Herbicides will only be
applied by personnel that are licensed by the State of Colorado to use and apply herbicides
16.Emergency Response Plan. Include a fire protection and hazardous materials spills
plan, which specifies planned actions for possible emergency events, a listing of
persons to be notified of an emergency event, proposed signage, and provisions for
access by emergency response teams. The emergency plan must be acceptable to the
appropriate fire district or the County Sheriff, as appropriate. The plan shall include a
provision for the operator to reimburse the appropriate emergency service provider for
costs incurred in connection with emergency response for the operator's activities at
the site.
EnCana has an Emergency Response Plan developed by Buys & Associates specifically for pipeline
construction. It is included in Attachment 7.
The following table lists contact information for Emergency Services Personnel:
Emeri~ency Phone Numbers
Utility Notification Center of CO (800) 922-1987
Garfield County Sheriff (970) 625-8095
Parachute Fire Department 911 or (970) 285-7711
Parachute Police Department 911 or (970) 285-7630
17. Traffic Impact. For construction traffic on county roads, indicate the anticipated types of
vehicles, number of each type, anticipated number of trips per day per each type,
county roads to be used, and percentage of the construction traffic that will travel on
each listed county road.
As currently planned, construction crews will access the project area via Rio Blanco County Road
5. Then access will be via existing ELM and private roads used for the energy industry. If EnCana
can acquire permission from Exxon, then Garfield County Road 215 will be used lo its terminus at
EnCana property. From that point access will be by existing roads used for the energy industry.
The numbers of vehicles that will likely be used to access the project are up to eight pickup trucks,
two semi trucks to haul equipment and pipe and possibly afuel truck. The majority af these trucks
will be making a single round trip per day to the project area. The semi trucks will make up to
three round trips depending on equipment and pipe needs.
18. Staging Areas. Indicate the general location of the staging areas required for pipeline
construction.
EnCana 's contractors will haul the pipe used for the project from a pipe wholesale distributor
located in Garfield County and no pipe yards or construction yards will be necessary for the
construction of the project. One staging area is proposed for the project. The area proposed as rhe
CDP will be graded and used to stage equipment and materials for the project. If the Land use
Change Permit for the CDP is denied then this staging area will be reclaimed.
19. Hydro-test Water. Indicate the quantity of water required, source of water and the
disposition of the water after testing.
Only one pipeline will be hydrostatically tested. The hydro test will require approximately 70,350
gallons of water. The water will come from Water Rights that EnCana holds on the Colorado River.
EnCana 's Water Rights Deed is provided in Attachment 2. After the completion of the hydro test,
the water will be discharged into the centralized remote frac pit to be used for drilling and
completion activities. If there is some remaining water left then EnCana will obtain a dewatering
permit from the State of Colorado to dis.charge the remaining water onto the ground surface.
20. GIS Compatible Electronic File. With the submission, provide an electronic file that is
compatible with the County's GIS system. The County's GIS is built on ESRI software
and any ESRl-compatible format is acceptable including shapefiles, coverages,
personal geodatabases, and file geobases. Preferred projection is Zone 13 NAD83 in
meters. The attribute list must include: pipeline owner's name, owner's address,
emergency contact phone number, pipeline commodity (i.e. natural gas), length of
pipeline, pipeline diameter, pipeline material (i.e. steel or PVC), and a general
description of pipeline route.
Upon completion of pipeline construction EnCana will provide GJS compatible files to Garfield
County.
Ill. REVIEW STANDARDS
Pipeline Development Plans will only be approved if they have adequately met the
following standards as required in Section 7-815. The Application should specifically
respond to each of the following standards:
1. Right-of-way and any associated facilities shall be located along the perimeters of
surface property ownerships and not within areas of agricultural crop production as
a general guide. Non-perimeter locations will be acceptable if the surface owner
agrees and there is no adverse impact on adjacent properties.
The proposed pipeline right-of ways cannot be constructed along property lines due to the.location
of the well pads and proposed facilities. EnCana is the surface owner and has no issues with the
proposed routes.
2. Any equipment used in construction or operation ofa pipeline must comply with the
Colorado Oil and Gas Conservation Commission Rules and Regulations, Section
802, Noise Abatement.
a. For any pipeline construction or operational facility that will have a
substantial impact in adjacent areas, additional noise mitigation may be
required. One or more of the following additional noise mitigation measures
may be required:
1. Acoustically insulated housing or covers enclosing any motor or engine;
2. Screening of the site or noise emitting equipment by fence or
landscaping;
3. A noise management plan specifying the hours of maximum noise and
the type, frequency, and level of noise to be emitted; and
4. Any other noise mitigation measures required by the COGCC.
b. All power sources used in pipeline operations shall have electric motors or
muffled internal combustion engines.
No operational facility is allowed within this application; no noise mitigation is proposed, no
acoustically insulated housings or covers are required and there is no noise emitting equipment to
fence or screen.
All equipment used in construction and operation of the pipelines will comply with COGCC Rules.
Because Garfield County will no longer allow CDP 's to be included with Pipeline Development
Plans the above requirements do not apply to this application.
3. Pipeline operations shall be located in a manner to minimize their visual impact and
disturbance of the land surface.
a. The location of right-of-way shall be away from prominent natural features
and identified environmental resources.
b. Right-of-way shall be located to avoid crossing hills and ridges, and
wherever possible, shall be located at the base of slopes.
c. Facilities shall be painted in a uniform, non-contrasting, non-reflective color,
to blend with the adjacent landscape. Right-of-way shall be located in
existing disturbed areas unless safety or visual concerns or other adverse
surface impacts clearly dictate otherwise.
Pipeline routes have been chosen to minimize impact to the surface. Where possible they follow
roads or existing pipeline right-of-ways. No prominent natural features or environmentally
sensitive resources will be impacted.
The above ground appurtenances will be painted in a uniform, non-contrasting and non-reflective
color.
4. Access points to public roads shall be. reviewed by the County Road & Bridge
Department and shall be built and maintained in accordance with the Garfield
County Road Specifications. All access and oversize or overweight vehicle permits
must be obtained from the County Road & Bridge Department prior to beginning ·
operation. All proposed transportation right-of-way to the site shall also be reviewed
and approved by the County Road & Bridge Department to minimize traffic hazards
and adverse impacts on public roadways. Existing roads shall be used to minimize
land disturbance unless traffic safety, visual or noise concerns, or other adverse
surface impacts clearly dictate otherwise. Any new roads created as a result of the
pipeline construction, intended to be permanent for maintenance and repair
operations shall be placed behind a locked gate or other barriers preventing use by
recreational vehicles. Any gates or barriers need to be consistent with the surface
owner's preferences.
As currently planned, construction crews will access the project area via Rio Blanco County Road
5. Then access will be via existing BLM and private roads used for the energy industry. If EnCana
can acquire permission from Exxon, then Garfield County Road 215 will be used to its terminus at
EnCana property. From that point access will be by existing roads used for the energy industry.
No new access points will be constructed onto Garfield County Roads.
5. In no case shall an operator engage in activities which threaten an endangered
species.
EnCana or its contractor will not engage in activities that threaten an endangered species.
6. Air contaminant emissions shall be in compliance with the applicable permit and
control provisions of the Colorado Air Quality Control Program, Title 25, Resolution
7, C.R.S.
Air emissions will be in compliance with the Colorado Air Quality Control Program.
7. All operations shall comply with all applicable State Public Health and Environment,
Water Quality Control standards.
All operations will comply with all applicable State Public Health and Environment, Water Quality
Control standards.
8. Any proposed waste disposal or treatment facilities shall comply with all
requirements of the County Individual Sewage Disposal System Regulations.
No JSDS Systems are proposed for the project.
The construction right-of-way will be maintained in a sanitary condition at all times and waste
materials on the project will be disposed of promptly at an appropriate waste disposal facility.
Waste includes, but is not limited to, human waste, trash, garbage, ashes, welding rods, etc.
Portable toilets will be available on-site. Liquid and solidwaste genera!ed during construction of
the project will be disposed of in an approved manner at an appropriate facility so as not to impact
air, water, soil, vegetation, or wildlife.
9. The proposed reclamation plan shall provide for a reasonable reclamation schedule
in light of the specific surface use and surrounding land uses, and may reql:lire ··
recontouring and revegetation of the surface to pre-disturbance conditions. The
Planning Director may also approve a plan for an alternative post disturbance
reclamation, provided the surface owner and the applicant agree, and the plan is.in
harmony with the surrounding land uses and the Comprehensive Plan.
The right-of-way will be graded as near as possible to the pre-construction contours and natural
runoff and drainage patterns will be restored. The right-of-way will be left in a roughened
condition to provide mirco-climatesfor plant development and collection of stormwater runoff.
Seeding and reclamation activities will begin after final clean-up activities have been completed on
each portion of the project or during the next seeding window in the spring or fall. Disturbed areas
will be reseeded with the NP R Upper Zone Seed Mix. EnCana will only use seed that is certified
weed-free. Seed bag tags will be collected and submitted to the Garfield County Vegetation
Manager. Seeding rate will be listed as pounds per acre of pure live seed (P LS).

TYPE OF APPLICATION: P1peltne Development Plan
I. GENERAL PROJECT DESCRIPTION
The proposed pipelines will mterconnect 4 well pads with the following proposed facilities:
a compressor station, a centalized frac pad and a central delivery pomt (CDP). The central
delivery point separates liquids (water and hydrocarbon condensate) from the gas produced
by each well. In order to reduce the size of the gas pads, there will be no frac tanks on
the well pads. Instead, the frac fluid will be pumped from a central frac pad to the well
pads. Only the p1pel1nes are part of this appl1cat1on. The comr-ressor station, centralized
frac r-ad and central delivery point will be approved through separate land use applications.
There will be 3 pipelines serving each well - -(I) a pipeline for dehvenng frac fluids to the
well, (2) a pipeline delivering lift gas to the well tn order to air-lift water out of the well, and
(3) a ~hase pipeline that will transport a mixture of the qas, condensate and water to the
CDP.
In addition, up to six parallel pipelines in th~ same trench are proposed to transport gas
and fluids between the compressor station, the CDP, the wells and the frac pad to
transport. The six types of pipelines will transport the following fluids/gases: (I) lift gas
going towards the wells for air-hftmg out of the wells, (2) produced natural gas leaving the
CDP and going towards the compressor station, (3) condensate li<jUld (hydrocarbons)
separated from the gas at the CDP and going towards the compressor station, (4) water
separated from the gas at the CDP and then going towards the compressor station or tlie
frac pad, (5) frac fluid moving from the frac pad towards wells, and (G) 3-phase moving from
wells to the CDP.
Final pipe sizes have not been determined. Encana's appl1cat1on will. list the maximum pipes
size that could be used (1.e. up to I G" diameter). After construction Encana will provide a
final as-built GIS file.

1.0 INTRODUCTION
1.1 PROJECT DESCRIPTION
EnCana Oil & Gas (USA) Inc. (EnCana) is planning to conduct drilling operations to develop
gas reserves on EnCana's Story Gulch lease units. The Liberty Gathering Pipeline Project
involves the construction, operation, and maintenance of four well connect pipelines that will
include one up to 12-inch diameter, 3-Phase (unprocessed natural gas) pipeline, one up to 16-
inch diameter, water pipeline and one up to l 0-inch gas lift pipeline installed within the same
trench line along the routes. The Liberty Gathering Pipeline Project will also involve the
construction, operation, and maintenance of three trunk pipelines in ·the same right-of-way which
will consist of one up to 20-inch diameter, natural gas trunk pipeline, one up to 12-inch liquids
pipeline and one up to 16-inch water pipeline. All proposed pipelines will be buried.
One new Central Delivery Point (CDP) metering and separation facility will be constructed and
will be permitted with Garfield County separately. The pipelines and related above-ground
facilities will be entirely located in Garfield County, Colorado on lands owned by EnCana.
The gathering system for the project will consist of a 3-Phase gathering process .. The 3-Phase
gathering process will involve collecting the unprocessed natural gas at the well heads and
transporting the unprocessed natural gas to a CDP facility. The CDP will be located at a site
lower in elevation from the proposed well pads to allow gravity to efficiently transport the
unprocessed natural gas from the well pads to the CDP facility. The. system will gather
unprocessed natural gas from the well pad sites and transport the natural gas and produced water
through one common pipeline (3-Phase) to the proposed CDP facilities. Separation of the
natural gas and produced water will occur at the CDP facilities. The CDP facility will be
constructed on a 2.7 acre graded pad. The 3-Phase line will enter into a vessel at the CDP site
where the natural gas, condensate and water will be separated. From this vessel the natural gas
will flow through a meter nm and down the dry gas pipeline. The condensate will flow thrm1gb
a LACT system and will be pumped into the liquids line. The water will enter the water skid and
either be pumped to the J25 Frac Paci or into the liquids line. The proposed natural gas and
produced water/condensate trunk pipelines leaving the CDP's will connect into existing EnCana
pipeline systems for delivery of the natural gas and produced water to the existing Middle Fork
Compressor Station and the Miclclle Fork Water Storage Recycling Facility located in Section 30,
Township 5 South, Range 96 West.
An additional water line and frac line will be used to move water to and from the Middle. Fork
Water Storage Recycling Facility to the J25 Frac Pad for drilling and completion activities. The
gas lift lines will be used to aid in the production of natural gas from the well bore.
In order to minimize environmental impacts, EnCana is planning on installing multiple pipelines
within the same right-of-ways and trenches. Figure D l shows the proposed pipeline routes as
well as the number, maximum size and types of pipelines that will :1e installed along the pipeline
routes.
The proposed gathering system and trunk line will contain a total of 98,191 feet of buried
pipeline constructed within 30,828 feet of right-of way. The proposed gathering system will
consist of approximately 3.6 miles of gas pipelines, approximately 4.45 miles of water pipelines,
approximately 3.6 miles of liquid pipelines, approximately 2 miles of 3-Phase pipelines,
approximately 3.1 miles of gas lift pipelines and approximately 1.8 miles of frac pipelines. The
maximum right-of-way width will be 120 feet but will be minimized when possible. The right-
of-way will be minimized by utilizing existing roads and existing pipeline right-of-ways when
possible and when fewer pipelines will be installed in the same trench and when surrounding
topography is flatter and does not require significant side cuts. A total of 30,828 feet (5.8 miles)
of right-of way will be constructed for the project.
1.2 PURPOSE AND NEED
EnCana plans to increase production in the Piceance Basin by approximately 100 to 200 million
standard cubic feet per day (MMscfd), each year, for the next several years. The Liberty.
Pipeline Project will provide a natural gas gathering system that will transport the projected
future volumes of natural gas from the Story Gulch lease unit to major interconnections with
other interstate pipelines. The proposed pipelines will transport approximately 70 MMscfd of
natural gas from the Piceance Basin of western Colorado to existing interstate and intrastate
pipelines.
1.3 LOCATION
1.3.1 Well Connects
The proposed Liberty Gathering Pipeline Project will consist of four well connect routes as well
as a route for water and frac water. The well connect routes will have up to three pipelines
collocated with the same trench.
The B36 496 well connect will flow into the J25 496 CDP. This will consist of an up to 12-inch
3-Phase line along with an up to 16-inch frac water and up to \0-inch gas lift from the B36 496
well pad to the M30 495 Tie-in. From the M30 Tie-in to the J25 496 CDP there will just be an
up to 12-inch 3-Phase line (combined 3-Phase well connect for the M30 and B36). There are
two proposed options for this route. One option is to construct the pipeline to generally follow
the contour along the slope to the CDP. The other option is to bore from the CDP to the M30 tie
in. The bore will minimize surface disturbance impacts. A 1,000 feet-long by 50 feet-wide extra
work space will be needed to complete the bore. This c:xtrn work space: will be used to lay out
and weld the bore pipe so it can be pulled back to the CDP pad.
From the M30 495, an up to 12-inch 3-Phase line will connect with the 1336 496 well connect.
The up to 16-inch frac water and up tolO-inch gas lift pipelines will follow the M30 495 3-Phase
line to the pad.
The D36 496 to the .!25 496 CDP well connect will contain an up to 16-inch frac water line, an
up to 10-inch gas lift line and an up to 12-inch J.-Phase. )ine.
From the J25 496 CDP to the proposed .!25 496 remote frac pad there will be an up to 16-inch
water and up to 16-inch frac line and an up to I 0-inch gas litl line. The gas lift and frac water
line will continue from the .!25 496 frac pit to the intersection with the B36 496 tee following the
2
existing road with just a couple of minor road reroutes. From the B36 tee these lines will
continue to the B36 496 and M30 496 pads.
1.3.2 Trunk Pipelines
A new trunk pipeline route will be constructed for the project. The Liberty Trunk pipeline route
will run from the 125 496 CDP to a single tie-in point with existing pipelines located in the NW
1;:; of the NE v.i of Section 3, Township 5 South, Range 96 West. Within this route there will be
an up to 12-inch liquid (water/condensate), an up to 16-inch water line and an up to 20-inch gas
pipeline and an up to 16-inch water pipeline. An additional up to I 0-inch gas lift pipeline will be
placed within the same trench between the F26 496 tie-in and the 125 496 CDP. The "trunk ·
pipeline route will generally require a right-ofway of 120-feet in width for a total length of
19,008 feet (3.6 miles). The route will parallel an existing pipeline right-of.way and an existing
road.
1.3.3 Central Delivery Point Facilities
The project will also involve the construction, operation, and maintenance of one new CDP
facility. The CDP facility will be on one larger pad located in the NWSE V1 of Section 25,
Township 4 South, Range 96 West, 6'h P.M. The CDP facility will be constructed on a 2.7 acre
graded pad. The CDP will be permitted with Garfield County· under a separate permit
For the construction of the pipeline, the CDP location will be graded and tised as a staging area.
Once the Land Use Change Permit for the CDP has been issued, the staging area will be used for
constructing the CDP facility. If the permit for the CDP is not issued then the staging area will
be reclaimed.
1.4 FACILITIES
1.4.1 Project Design
The proposed project is approximately 2 miles of up to 12-inch diameterstecl, buried, tlrree-
phase pipeline, approximately 3 .6 miles of up to 20-inch diameter steel, buried, natural gas
pipeline, approximately 3.6 miles of up to 12-inch diameter steel, buried, liquids pipeline,
approximately 4.45 miles of up to 16-inch diameter steel, buried, water pipeline, 1.8 miles of up
to 16-inch diameter steel, buried, frac pipeline. 3.1 miles of up to 10-inch diameter steel, buried,
gas lift pipeline and aboveground facilities. Above ground facilities include multiple block
valves, side block valves, launcher/receivers, and cathodic protection devices insrnlled along the
right-of-way as necessary. EnCana will design and construct the pipelines and related facilities in
conformance with the requirements of Title 49 CFR, Part 192, "Regulations for the
Transportation of Natural Gas and Other Gas by Pipeiine: Minimum Federal Safely Standard",
Part 195, 'Transportation of Hazardous Material by Pipeline" and ASME B31.8 Design Code.

1.5 LAND REQUIREMENTS
1.5.1 Right-of-Way
The construction right-of-way will normally consist of a maximum of 120 feet of work area for
the construction of the pipelines and after the completion of the project; the right-of-way will
revert back to a 60 foot permanent easement for operation of the pipelines.
Approximately 87.7 acres will be impacted for the Liberty Pipeline Project. The entire project
will be on lands owned by EnCana.
The proposed pipelines will be constructed at the edge of adjacent road or pipeline rights-of-way
when possible. The off-set will vary depending on the number of existing pipelines within the
corridor, terrain and/or environmental features. In some areas however, the right of way will be
constructed through undisturbed land to maintain grade for the unprocessed natural gas to flow to
the CDP.
The proposed Staging Area/CDP location will require a graded pat! of 2.7 acres. An additional
extra work space 50 feet wide by 1000 feet long will be graded if the J25 CDP to M30 tie-in bore
is chosen. This will be an extra 0.1 acres of disturbance.
1.5.2 Corridor
EnCana has selected routes that will primarily parallel existing road right-of-ways, or existing.
utility corridors. EnCana has made efforts to route the pipelines to avoid areas of potential visual
impact in cross-country sections of the pipeline right-of-way.
1.5.3 Disturbance
The Liberty Pipeline Gathering Project will disturb approximately 85 acres for pipeline
construction and 2.7 acres for the Staging Area/CDP in Garfield County. The entire disturbance
is on EnCana owned lands.
1.5.4 Contractor/Pipe Storage/Offloading Yards
There are no Contractor Yards, Pipe Storage Areas or Offloading Yards proposed for the project.
1.5.5 Access Roads
EnCana will use existing access roads to gain access to right-of way during construction. These
access roads are primarily gravel and/or dirt roads utilized by the oil and gas industry. There will
need to be some road upgrading and minor route changes. Where deviations to the existing road
occur, that section of road will be reclaimed using EnCana's Reclamation Plan.
1.5.6 Aboveground Appurtenances
Aboveground facilities include vessels, block valves, side block valves, launcher/receivers and
cathodic protection devices. After completion of reclamation activities, aboveground pipeline
markers will be installed over the center of each pipeline.

2.2 CONSTRUCTION SCHEDULE
Construction activities are tentatively scheduled for March 2010 and will continue into the fail of
2011 or as weather and drilling operations allow. Working hours will normally range from 7:00
AM to 5:00 PM Monday through Saturday.
Construction activities will take approximately 24 to 32 weeks and will begin upon approval
from the Garfield County Planning Director. The duration of construction may vary depending
on drilling operations.
2.3 CONSTRUCTION METHODS
2.3.1 Plan of Development
EnCana has developed a Plan of Development, which describes construction methods and
measures to be taken by EnCana during construction, operation, and maintenance of the project.
The Plan of Development is provided to project personnel to establish guidelines for construction
and operation of the project and to address mitigation measures that 1vere identified in the
Sensitive Resource Survey, Weed Management Plan, NPR Reclamation Plan, and Environmental
Assessment.
2.3.2 Construction Sequence
The following section provides a description of each phase of standard construction during the
project. The following operations arc typical in a construction spread.
2.3.2.1 Engineering Surveys
The construction right-of-way will be marked prior to construction with laths and/or flagging.
Laths/flagging will be maintained throughout construction and will not be removed until after
reclamation activities have been completed.
2.3.2.2 Clearing, Grading, and Topsoiling
Clearing, topsoiling, and grading will be limited to the mimmum area required for safe and
efficient construction. Clearing will be performed only to the extent necessary to allow for
construction activities. Every effort will be made to salvage root systems. The majority of the
current vegetation along the proposed right-of-way consists of oakbrush-sagebrush-grassland
species. EnCana's contractors will use a mower to cut and mulch the existing vegetation to
ground level. Every effoti will be made to salvage root systems. Along sections of the right-of-
way where oakbrush or other larger trees are present the larger vegetation will be hand-cut and
stacked along the edge of work area for later use in reclamation activities.
Available topsoil, up to a depth of six inches will be segregated from the trenchline only. On any
lands requiring grading, topsoil will be stripped from the entire portion .of the right-of-way that
requires grading. Topsoil will be removed and stockpiled, and the right-of-way will be graded
only to the extent necessary to create safe and efficient pipeline installation conditions. At the
fee-landowners request, up to 10 inches of topsoil may be segregated from the trench and spoil
sides of the right-of-way and the entire portion of the right-of-way may be stripped of available .
topsoil if grading is required.
2.3.2.3 Trenching
The ditch will be excavated and sloped in accordance with OSHA specifications, The cover from
top of pipe to ground level will be a minimum of 36 inches. Where rock is encountered, tractor-
rnounted mechanical rippers or rock trenching equipment may be used to facilitate excavation.
The bottom of the trench line will remain free of rocks and debris to allow for a solid surface to
install the pipe.
The trench will be excavated and subsoil material stockpiled at the edge of the workspace. Based
on field conditions, gaps will be made in subsoil stockpiles to avoid ponding or excessive
diversion of natural runoff during storm events.
2.3.2.4 Pipe Installation
Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment,
welding the pipe segments together, coating the joint areas tu prevent corrosion, and thc.n
lowering-in and padding as described in greater detail below.
Stringing
Pipe will be hauled by truck to the pipeline right-ot~way. Each joint of pipe will be unloaded and
placed parallel to the ditch. Each section of pipe will be stacked on timber skids to stabilize the
pipe until welding is completed.
6
Bending
After the joints of pipe are strung along the ditch, individual joints of pipe will be bent to
accommodate horizontal and vertical changes in direction. Field bends will be made utilizing a
hydraulically operated bending machine. Where the deflection of a bend exceeds the allowable
limits for a field-bent pipe, factory (induction) bends will be installed.
Welding
After the pipe joints are bent, the pipe will be lined up end-to-end and clamped into position. The-
two joints of pipe will be evenly spaced within the clamps to ensure that the pipes are properly
aligned, before welding begins. The pipe is then welded in conformance with 49 CFR Part 192,
Subpart E. "Welding of Steel Pipelines" and AP! 1104, "Standard for Welding Pipelines and
Related Facilities".
Welding Inspection
Welds will be visually inspected by a qualified inspector. In addition, 10 percent of the welds on
the pipelines will be x-raycd. Any defects will be repaired or cut out as required under the
specified regulations and standards.
Coating
To prevent corrosion, the pipe will be externally coated with fusion bonded epoxy coating prior
to delivery. After welding, field joints will be coated with fusion bond epoxy coating, tape and
primer, or shrink sleeves. Before the pipe is lowered into the ditch, the pipeline coating will be
visually inspected and tested with an electronic detector, and· any faults or scratches will be
repaired.
Lowering-in and Padding
Once the pipe coating operation has been completed, a section of the pipe will be lowered into
the ditch. Padding or placement of sand bags along the bottom of the trench line may occur
before the pipe section is lowered-in, depending on the bottom surface of the trench. Side-boom
tractors will be used to simultaneously lift the pipe, position it over the ditch, and lower it in
place. Inspection will be conducted to verify that minimum cover is· provided; the trench bottom ·
is free of rocks, debris, etc ; external pipe coating is not damaged; and the pipe is properly fitted
and installed into the ditch. Specialized padding machines will be used to sift soil fines from the
excavated subsoil to provide rock-free pipeline padding and bedding. In rocky areas, padding
material or a rock shield will be used to protect the pipe. Topsoil will not be used to pad the pipe.
2.3.2.5 Backfilling
Backfilling will begin after a section of the pipe has been successfully placed in the ditch and
final inspection has been completed. Backfilling will be conducted .using. J bulldozer, rotary.
auger backfill, padding machine or other suitable equipment. Backfilling the trench will use the
subsoil previously excavated from the trench. Backfill will be graded and compacted, where
necessary, for ground stability, by being tamped .or walked in with a wheded or track vehicle ....
Compaction will be performed to the extent that there are no voids in the trench. Any excavated
materials or materials unfit for backfill will be utilized or properly disposed of in conformance
with applicable laws or regulations. Topsoil will not be used to backfill the trench.
7
2.3.2.6 Cleanup
Cleanup activities will be initiated as soon as practicable after backfilling activities have been
completed. All construction-related debris will be removed and disposed of at an approved
disposal area. The right-of-way will be graded as near as possible to the pre-construction
contours and natural runoff and drainage patterns will be restored. The right-of-way will be left
in a roughened condition to provide mirco-climates for plant development and collection of
stonnwater runoff.
2.3.3 Road Crossings/Installation
The proposed pipeline will not cross any Garfield County roads along the project route. The
project will be installed across several two track roads and industrial roads on EnCana property.
The pipeline will be buried at least 60-inches underneath the mad surface t0 ensure proper .
protection of the pipeline.
2.3.4 Drainage and Stream Crossings/Installation .
The Liberty Pipeline Gathering Project will not involve crossing any intermittent or perennial
drainage along the proposed routes.

2.7 SENSITIVE AREA SURVEYS
WestWater Engineering Inc. (WestWater) has completed the biological assessments of the NPR
from 2004 to the present. The Liberty Pipeline Project area was surveyed for sensitive resources
during the fall of 2009. The Sensitive Resource Report for the Liberty Pipeline Project is
provided in Attachment 4.
2.8 REVEGETATlON
Seeding and reclamation activities will begin after final.. clean-up activities have been completed
on each portion of the project or during the next seeding window in the spring or fall. Disturbed
areas will be reseeded with the NPR Upper Zone Seed Mix. EnCana will only use seed that is
certified weed-free. Seed bag tags will be collected and submitted to the Garfield County
Vegetation Manager. Seeding rate will be listed as pounds per acre of pure live seed (PLS).

The right-of-way will be scarified, tilled, harrowed, or roughened to a depth of 3 to 4 inches prior
to seeding, where needed, to prepare the seedbed and improve revegetation potential. Seed will
be placed in direct contact with the soil at an average depth of 0.5-inches, covered with soil, and
10
firmed to eliminate air pockets around the seeds. Seed will be applied using a rangeland seed
drill with a seed release and agitation mechanism sufficient to allow seeds of various sizes and
densities to be planted at the proper seeding depth. Broadcast seeding will be employed only in
areas where drill seeding is unsafe or physically impossible. Broadcast application rates will be
double the drill rate. Immediately after broadcasting, the seed will be uniformly raked, chained,
or dragged to incorporate seed to a sufficient seeding depth.
Upon completion of seeding activities timber ·slash and larger shrubs that were previously
cleared from the work area will be scattered along the reclaimed right-of-way to aid in soil
stabilization and to minimize OHV traffic.
The NPR Reclamation Plan is provided in Attachment 5. The NPR Reclamation Plan describes
in greater detail the restoration guide for disturbed lands on the NPR from the· result of
constructing well pads, roads, and pipelines.
EnCana will provide a revegetation security to Garfield County for the amount of $212,250 or
$2,500 per acre of disturbance on fee surface for the Liberty Pipeline Gathering Project. The
security deposit certificate is provided in Attachment 6.
2.9 WEED MANAGEMENT PLAN
WestWater completed an Integrated Vegetation and Noxious weed report for the Libe11y Pipeline
Gathering Project. Four Colorado State Listed noxious weeds were identified as likely to occur
in the project area. Two of these species are listed by Garfield County as noxious weeds.
Species include common mullein (Verbascwn thopsis), Musk thistle (Carduus nuwn.1),
houndstongue (C)mog/ossum officinale) and cheatgrass (Bromus tectorum).
EnCana has an Integrated Vegetation Management Plan for noxious weed control and
reclamation which was prepared by WestWater in 2009. EnCana will follow this plan and
recommendations by WestWatcr to control the spread of noxious weeds. This Plan is included in
Attachment 5. The following measures identify how EnCana will use Best Management
Practices to control and reduce the spread of noxious weeds:
Ensure that equipment used on the project is clean and free of noxious weeds before arriving
at the project. Cleaning will be completed using either high-pressure water or compressed air
to remove potential weed seeds.
Minimize soil disturbance to reduce areas of potential noxious weeds. Equipment and. project
vehicles will be confined to the flagged project right-of-way to minimize excess soil
disturbance.
Salvage and segregate topsoil, then redistribute to reclaim the right-of-way.
Disturbances will be kept to a minimum.
Establish native grasses and forbs. The NPR Reclamation Plan included in Attachment 8 has
identified the appropriate seed mixes for reclamation of disturbed areas.
Eradicate weed introductions early through the uses of herbicides. Herbicides will only be
applied by personnel that are licensed by the State of Colorado to use and apply herbicides.
11
2.10 EMERGENCY RESPONSE
The EnCana Emergency Response Plan is provided in Attachment 7.
The following table lists contact information for Emergency Services Personnel:
Emergencv Phone Numbers
Utilitv Notification Center of CO ___ __(800) 922-1987
Garfield Countv Sheriff (970) 625-8095
Parachute Fire Department 911or(970)285-7711
Parachute Police Department 911 or (970)285-7630
2.11 TRAFFIC IMPACT
EnCana will likely use Rio Blanco County Road 5 to access existing BLM and private roads to
gain access to the right-of-way during construction. These access roads are primarily gravel
and/or dirt roads utilized by the oil and gas industry. If an agreement can be made with Exxon,
then access would be via Garfield County Road 215 to EnCana's NPR at the end of CR 215.
From there, privately owned oil and gas industry roads would be used.
The numbers of vehicles that will likely be used to access the project are up to eight pickup
trucks, two semi trucks to haul equipment and pipe and possibly a fuel truck. The majority of
these trucks will be making a single round trip per clay to the project area. The semi trucks will
make up to three round trips depending on equipment and pipe needs.
2.12 STAGING AREAS/CONSTRUCTION YARDS
EnCana's contractors will haul the pipe used for the project from a pipe wholesale distributor
located in Garfield County and no pipe yards or construction yards will be necessary for the
construction of the project. One staging area is proposed for the project. The 2.7 acre area
proposed as the CDP will be graded and used to stage equipmen.t ancl materials for the project. If
the Land use Change Permit for the CDP is denied then this staging area will be reclaimed.
2.13 HYDROTESTWATER
Only one of the Liberty Pipeline Gathering Project pipelines, the gas lift pipeline, will be
hyclrostatically tested. EnCana will use its water rights to. draw waler out of the Colorado River.
The necessary water will be pumped and transported into the gas lift line by using an existing
pipeline. No water will be trucked to the project area for hydrostatic testing. The remaining
pipelines will pneumatically tested with natural· gas or nitrogen prior ro being placed into. service. ··
Alter the completion of the hydro test, the water will be discharged into the centralized remote
frac pit to be used for drilling and completion aclivilies. lf there is· some remaining-water:·leJt·
then EnCana will obtain a dewatering permit from the State of Colorado to discharge the
remaining water onto the ground surface. EnCana's water rights document is provided in
Attachment 2.
12
3.0 POST-CONSTRUCTION ACTIVITIES
3.1 MAINTENANCE AND OPERATION
EnCana will maintain the right-of-way for the life of the project. Maintenance will include
repairing soil erosion and reseeding as necessary. The right-of-way will be considered
satisfactorily reclaimed by the fee-owner and the Garfield County Vegetation Management
personnel when soil erosion has been stabilized and a vegetative-cover at least equal to that
present prior to disturbance and a plant species composition at least as desirable as that present to
the disturbance is established. Establishment of all the species in the seed mixture will be
considered as meeting the composition/desirable species criteria.
EnCana will monitor the right-ot~way for noxious weed infestations and shall control noxious
weeds as requested by EnCana and Garfield County Vegetation Management personnel.
EnCana's gathering system is operated according to natural gas industry standards. Supervisors
and field personnel will monitor and control the system by driving. throughout the project area
inspecting facilities on a periodic basis. Disposal of any liquid and solid waste generated during
maintenance and operation of the pipeline will be clone at an approved faeility in an
environmentally sound and approved manner.
4.0 MITIGATION MEASURES
The following protective measures have been adopted by EnCana to address specific resource
values and environmental concerns associated with the project..
4.1 NOXIOUS WEEDS
All construction equipment and vehicles will be Clean and free of soil and weed seed prior to
moving equipment and vehicles onto the EnCana NPR property at the start of construction.
Cleaning shall be accomplished by high-pressure washing with wat1:Tor compressed air. EnCana
will monitor the right-ot~way for noxious weed infestations and shall control noxious weeds as
necessary. The Weed Management Plan is provided in Attachment 5.
The following measures identify how EnCana will control and reduce the spread of noxious
weeds:
Ensure that equipment used on the project is clean and free of noxious weeds before arriving
at the project. Cleaning will be completed using either high-pressure water or compressed air
to remove potential weed seeds.
Minimize soil disturbance to reduce areas of potential noxious weeds. Equipment and project
vehicles will be confined to the flagged project right-ot~way to minimize excess soil
disturbance.
Salvage and segregate topsoil, then redistribute to reclaim the right-of-way.
Temporary disturbances will be kept to a minimum.
13
Establish native grasses and forbs. The NPR Reclamation Plan included in Attaclunent 8 has
identified the appropriate seed mixes for reclamation of disturbed areas.
Eradicate weed introductions early through the uses of herbicides. Herbicides will only be
applied by personnel that are licensee! by the State of Colorado to use and apply herbicides.
4.2 EROSION AND STORMWATER
Temporary and permanent erosion control measures will be implemented to control erosion and
transport of sediment. Erosion and sediment controls will be used and maintained during all
phases of construction, as necessary. Selection of appropriate erosion controls will be selected
based on soil properties, steepness of the slope, and anticipated surface flow or runoff. During
cleanup, the right-of-way will be graded as near as possible to the pre-construction contours and
natural runoff and drainage patterns will be restored. Permanent waterbars will be constructed
along all slopes in excess of five percent in gradient.
The Stormwater Management Plan included in Attachment 3 provides further mitigation
measures to be implemented during construction and operation of the pipeline.
4.3 THREATENED, ENDANGERED, AND SENSITIVE SPECIES
WestWater biologists completed extensive field surveys on the NPR for the Greater sage-grouse
and other sensitive avifauna listed by the U.S. Fish and Wildlife Service in the Birds of
Conservation Concern within the area of the proposed Libe1ty Pipeline Gathering System in
summer of 2009. A single lek active in 2008 is within 1.8 miles of the nearest pipeline.
WestWater believes that construction activity will not affect the kk due to lhe distance and
topography between the pipeline and the lek.
EnCana has treated areas on their property, to improve Greater sage-grouse habitat by removing
thick stands of service berry and oakbrush. This habitat improvement· will cominue in the future.
WestWater has completed surveys on the NPR for active and inactive raptor nests during the
summers of 2005 through 2009. Sixteen nests were obse1vecl within .33 miles of the project
area. Of these, 11 were active and 5 were not. WestWater biologists will perform additional
rap tor surveys during the 20 l 0 nesting season lo identify active raptor nests. If the raptors are
observed nesting at the previously identified sites or new nesting locations, then timing limitation
restrictions would be considered to minimize impact to the raptors.
Biological surveys were completed for federally listed threatened and endangered plants and
BLM sensitive species plants in the project area in summer of 2009. West Water biologists have
concluded that threatened and endangered or sensitive species plants do nor likely occur i11 the
project area.
The Sensitive Resource Report for Liberty Pipeline gathering System is included in Attachment
4.
4.4 CULTURAL RESOURCES
A Class III Cultural Resource Inventory was conducted by Grand River Institute for the entire
Liberty Pipeline Project. No cultural resources were identified during the inventory. The
following mitigation measures will be followed during construction and operation of the project:
All persous in the area who are associated with this project must be informed that if anyone
is found knowingly disturbing historic, archaeological, or scientific resources, including
collecting artifacts, the person or persons will be subject to prosecution and dismissal from
the project.
The BLM Authorized Ot11cer will be notified, by telephone, with written confirmation,
immediately upon the discovery of human remains, funerary items, sacred objects, or objects
of cultural patrimony. Activities must stop in the vicinity of the discovery and the discovery
must be protected for 30 clays or until notified to proceed by the Authorized Officer.
If in connection with operations under this contract the project proponent, his cnntractors,.
subcontractors, or the employees of any of them, discovers, encounters or becomes aware of
any objects or sites of cultural or paleontological value or scientific 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 resourc,e
and shall notify the BLM authorized officer of the findings. Operations may resume at the
discovery site upon receipt of written instructions and authorization. by the Authorized
Officer.
4.5 AIR QUALITY
Dust shall be controlled by the use of water or an approved dust suppressant, as directed by
Garfield County.
4.6 SOLID WASTE MANAGEMENT
The construction right-of-way will be maintained in a sanitary condition at all times and waste
materials on the project will be disposed of promptly at an appropriate waste disposal facility.
Waste includes, but is not limited to, human waste. trash, garbage. ashes, welding rocb, etc.
Portable toilets will be available on-site. Liquid and solid waste generated during construction of
the project will be disposed of in an approved manner at an appropriate facility so as not to
impact air, water, soil, vegetation, or wildlife.
4.7 HAZARDOUS MATERIALS MANAGEMENT
Hazardous materials (substances) used during project construction may include solvents and
other substances. In addition, petrnlcnrn mcducts such as-gasoline, diesel fuel, lubricaling ails,
and hydraulic fluid will be used. To prevent the accidental release of hazardous materials and
petroleum products, activities shall comply with EnCana's Spill Prevention, Containment, and
Countermeasure (Spill) Plan, which is summarized below and provided in Attachment 8.
The Spill Plan:
15
Identifies emergency notification and state agency names and phone numbers that shall be
contacted in the event of a spill;
Requires sufficient supplies of absorbent and barrier materials on hand to allow for rapid
containment and recovery of spills; and
Includes instructions for the collection and disposal of. waste, so.ii, and other materials
generated during, and cleanup of, a spill.
The following precautions shall be taken to ensure that a reiease of petroleum and hazardous
materials is prevented or contained:
The project area will be inspected frequently to ensure proper use, storage, and disposal of
material.
Equipment and vehicles shall be inspected daily for leaks and receive regular preventative
maintenance to reduce the potential for leakage.
All materials will be stored in a neat, orderly manner. Containers larger than 55-gallons will
be stored in secondary containment structures that allow for ll 0 percent capaci1y phis
potential precipitation.

1.0 Introduction
This Master Stormwater Management Plan (Master SWMP) satisfies the Colorado Department of Public
Health and Environment (CDPHE) Water Quality Control Division (WQCD) General Permit No. COR-030000
issued on May 31, 2007 for Stormwater Discharges Associated with Construction Activities (the Stormwater
Construction Permit). EnCana Oil & Gas (USA) Inc. (EnCana) has submitted a General Permit Application to
WQCD, a copy of which is provided as Appendix A.
This Master SWMP has been prepared in compliance with CDPHE WQCD, the Federal Clean Water Act
(CWA), and the National Pollutant Discharge Elimination Permit (NPDES) regulations found in 40 CFR,
Part 122.26 for stormwater discharges.
The objectives of this Master SWMP are to:
1. Identify all potential sources of pollution which may reasonably be expected to affect the quality of
stormwater discharges associated with construction activity within this Master SWMP permit area at
each project site;
2. Describe the practices to be used to reduce the pollutants in stormwater discharges associated with
construction activity within this Master SWMP permit area at each project site (also known as Best
Management Practices (BMPs)); and ensure the practices are selected and described in accordance
with good engineering practices, including the installation, implementation and maintenance
requirements;
3. Be properly prepared and updated to ensure compliance with the terms and conditions of the
Stormwater Construction Permit;
4. Work hand in hand with the Site Specific Records, as described in the following section; and
5. Serve as an education tool and comprehensive reference/guide to stormwater management for
inspectors, surveyors, engineers, and EnCana employees and contractors.
EnCana construction activities fall under one of two types. Exploration and Production (E&P) sites involve the
construction of well pads, roads, and other facilities. Midstream SeNices (also referred to as Gas Gatl"tering)
sites involve the construction of pipelines and compressor, treatment, and other facilities. This Master SWMP
is intended to address stormwater management for any and all of these sites within this Master SWMP's
Permit Coverage Area.
1.1 Site Specific Records
While Volume 1 of the Master SWMP contains all of the general permit area information, Volume 2 of the
Master SWMP contains all of the Site Specific Records including all Individual Stormwater Site Plans (Site
Plans), as discussed in Section 2.8, and all Inspection and Maintenance Reports (discussed in Section 5.4).
These Site Specific Records contain information specific to each site (each well pad, compressor station,
section of road/pipeline, etc.), including information on areas of disturbance, ecosystems and vegetation, soil
types, percent pre-disturbance vegetation, etc. Any changes to the design of individual sites or the BMPs
used at those sites will be noted on the Site Plans as those changes occur, and kept with the Site Specific
Records.
The Site Specific Records (Volume 2 of the Master SWMP) are bound separately from the body of this-Master
SWMP; however, both are readily available during any inspection. Both the body of this SWMP (Volume 1)
and the Site Specific Records (Volume 2) comprise the entire SWMP, and go hand in hand in keeping EnCana
in compliance with stormwater regulations. The Site Specific Records will be kept at the EnCana Field office in
Parachute during active construction and site inspections to ensure accurate implementation, inspections, and
maintenance of BMPs, as well as timely revisions to the Site Specific Records.
1-1 Revised June 2009

1-2 Revised June 2009
2.0 Narrative Description of Master SWMP Permit Coverage Area
Name of Permit Coverage Area: Piceance Creek/ Eureka/ Story Gulch Unit
Permit Number: COR-039167
Location of the Permit Coverage Area:
• County: Rio Blanco & Garfield Countys
• City: Located approximately 29 miles West/ North West of Parachute, Colorado. (See Site Maps for
distance to the waters of the state.)
• Township/Section/Range: PICEANCE CREEK-Townships 1S, 2S & 3S. Ranges 95W, 96W & 97W.
See Area Map for Sections.
• Latitude/Longitude: Latitude 39/47/40, Longitude 108/06/20.
Activities at the Permit Coverage Area will likely involve the construction of:
• Well pads
• Access roads
• Pipelines
• Compressor stations
The above construction activities are only typical and may vary once construction begins. Up-to-date
information on the construction of well pads, roads, pipelines, etc. will be kept with the Site Specific Records
(Volume 2 of the Master SWMP).
2.1 Sequence of Major Activities
Site specific, scheduling, surface use agreements, and/or other constraints can and/or may dictate changes in
construction sequences. Significant sequence changes are addressed in the Sile Specific Records (Volume 2
of the Master SWMP). Specific details on the construction and maintenance of BMPs mentioned below are
provided in the Stormwater Manual of Best Management Practices (BMP Manual) as discussed in Section 3.3.
2.1.1 Well Pads and Roads
Construction activities for well pads and roads are generally completed in the following sequence:
Preconstruction:
1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated.
2. Temporary BMP's. Where physical access is available, installation of terminal perimeter and
temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs
used for each site are shown on the Site Plans (discussed in Section 2.8} and kepi with the Site
Specific Records (Volume 2 of the Master SWMP).
Construction:
3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the
terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any
run-on-protection discharge points, and/or chipped or other depending on landowner requirements.
2-1 Revised June 2009
4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling,
diversions are to be placed for run-on-protection (ROP) to prevent the greater landscape from
discharging onto the planned disturbance. Temporary sediment control BMPs shall be placed at the
discharge points of the ROP until permanent erosion controls can be installed along the entire
length of the ROP. Diversions are to be installed along the terminal discharge edge inside of the
vegetation windrows to convey site water/sediment to terminal discharge points where rough
retention reservoirs are to be installed. The retention reservoir outlets are to receive temporary
sediment control BMPs until permanent retention reservoirs and erosion, drainage, and sediment
BMPs can be installed.
5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are
to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil
stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess
is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major
earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be
identified for immediate interim reclamation shall receive topsoil.
6. General Rough Grading. The site location will be graded to provide suitable surfaces for vehicle
traffic and/or building sites, and may be graded to establish surface drainage patterns, such as berms
or roadside ditches as necessary.
7. Facility Specific Grading. Individual facilities may require additional excavation to allow fbr
construction of foundations. Excess soil will typically be used in general site grading.
8. Foundation Construction. To support facilities (such as tanks, processing equipment, etc),
foundations will be constructed. Foundations may consist of select backfill, concrete spread footings,
or piles. Finished support elevations are to be installed twelve to eighteen inches (12-1"8") above
finished grade or the lowest point of the facility.
9. Facility Construction. Tanks, processing equipment, etc. will be constructed.
Interim Reclamation:
10. Gravel Surfacing. Areas used for access, parking, or materials staging will typically be gravel
surfaced.
11. Reclamation of Unused Areas. Areas not needed for facilities, roads, parking, or materials staging
will generally be reclaimed. Salvaged topsoil will be spread and lhe vegetative seed mix will be
applied.
12. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and.drainage.
crossings) additional measures may be applied to increase stability of the reclaimed area.
Final Reclamation:
13. Reclamation of Post-Operation Areas. When operation of weir pad or road' is no longer necessary,·
the area will be decommissioned and all newly disturbed areas will be reclaimed. Any remaining
topsoil will be spread and the vegetative seed mix will be applied. This may occur after termination of
this permit and under the coverage of a new construction permit.
2.1.2 Pipelines
Construction activities for pipelines are generally completed in the following sequence:
Preconstruction:
1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated.
2. Mark Right-Of-Way. The construction right-of-way (ROW) will be marked prior to construction with
laths and/or flagging.
3. Temporary BMPs. EnCana's stormwater inspectors will determine locations to install preconstruction
temporary erosion control devices, per site specific BMP installation plans and as necessary.
2-2 Revlsed June 2009
EnCana's contractor will maintain the erosion control structures as directed by the stormwater
inspectors throughout all phases of construction, or until permanent erosion control measures are
installed. Actual BMPs used for each site are shown on the Site Plans, which are kept with the Site
Specific Records (Volume 2 of the Master SWMP).
Construction:
4. Vegetation Clearing. If necessary, vegetation will be cleared and placed in a windrow at the edge of
the work area to be used later in reclamation activities, removed from the construction site, or
burned/chipped depending on landowner requirements. Details for windrows are provided within the
Stockpiling BMP of the BMP Manual (discussed in Section 3.3).
5. Topsoil Stripping. All ACCESSIBLE TOPSOIL (from the entire width of the right-of-way) will be
removed and temporarily stockpiled along the up-hill side of the right-of-way (ii terrain grades will
allow) for later use in reclamation activities.
6. General Grading. For pipeline segments that occur in relatively rough terrain. general grading will be
conducted to create a safe and workable ground surface. This is generally done to form a relatively
level work surface on steep cross slopes and to reduce slopes in undulating terrain (arroyo and wash
crossings). The site location will be graded to provide suitable surfaces for vehicle traffic and/or
building sites, and may be graded to establish surface drainage patterns, such as berms or roadside
ditches as necessary.
7. Trench Excavation. The trench needed for pipeline installation is almost always off-set in the ROW.
The surveyors may indicate the location of the trench on their pipeline lateral. Generally, the trench will
be located in the first third of the ROW. The remaining two thirds of the ROW will be used for working
space. The trench depth and width will vary with the number of pipes ta be instalted and the pipe·
diameter. Generally, a 4-foot deep trench will be excavated by track-mounted excavators. The ditch
will be excavated and sloped in accordance with OSHA specifications. The cover from top of pipe to
ground level will be a minimum of 36 inches. Where rock is encountered, tractor-mounted mechanical
rippers or rock trenching equipment may be used to facilitate excavation. The trench will be excavated
and subsoil material stockpiled within the confines of the approved right-of-way limits unless.a
temporary use area is approved from the proper agency. Trench spoil will be stored in a separate
location from the previously segregated topsoil.
8. Pipe Installation. Pipe installation will include stringing, bending for horizontal or vertical angles in
the alignment, welding the pipe segments together, coating the joint areas.ta prevent corrosion, and.
then lowering-in and padding.
9. Stringing. Pipe will be hauled by truck to the pipeline ROW. Each joint of pipe will be unloaded and
placed parallel to the ditch.
10. Bending. Alter the joints of pipe are strung along the ditch, individual joints of pipe may need to be
bent to accommodate horizontal and vertical changes in direction. Field bends will be made utilizing a
hydraulically operated bending machine. Wherethedeflection of abend exceeds the allowable· limits
for a field-bent pipe, factory (induction) bends will be installed.
11. Welding. After the pipe joints are bent, the pip.e is lined up end-to-end and clamped into position. The
pipe is then welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines"
and API 1104, "Standard for Welding Pipelines and Related Facilities".
12. Welding Inspection. Welds will be visualltinspected by aqualilieo inspector. Any defects will be
repaired or cut out as required under the specified regulations and standards.
13. Coating. To prevent corrosion, the pipe will be externally coated with fusion bonded epoxy coating
prior to delivery. Alter welding, field joints.will be coated with fusion bond epoxy coating, tape and
primer, or shrink sleeves. Before the pipe is lowered into the ditch, the pipeline coating will be visually
inspected and tested with an electronic detector, and any faults or scratches will be repaired.
14. Lowering-In and Padding. Once the pipe coating operation has been completed, a section of the
pipe will be lowered into the ditch. Side-boom tractors may be used to simultaneously lift the pipe,
position it over the ditch, and lower it in place. Inspection will be conducted to verify: that minimum
cover is provided; the trench bottom is free of rocks, debris, etc.; external pipe coating is not damaged;
2-3 Revised June 2009
and the pipe is properly fitted and installed into the ditch. Specialized padding machines will be used
to sift soil fines from the excavated subsoil to provide rock-free pipeline padding and bedding. In rocky
areas, padding material or a rock shield will be used to protect the pipe. Topsoil will not be used to pad
the pipe. At the completion of lowering-in and padding activities the contractor may install trench
breakers around the pipelines to minimize subsurface water flow. Details for trench breakers are
provided within the BMP Manual (discussed in Section 3.3).
15. Backfilling. Backfilling will begin after a section of the pipe has been successfully placed in the ditch
and final inspection has been completed. Backfilling will be conducted using a bulldozer, rotary auger
backfill, padding machine or other suitable equipment. Backfilling the trench will u.se the sub?oil
previously excavated from the trench. Backfill will be graded and compacted, where necessary for
ground stability, by being tamped or walked in with a wheeled or track vehicle. Compaction will be
performed to the extent that there are no voids in the trench. Any excavated materials or materials
unfit for backfill will be utilized or properly disposed of in conformance with applicable laws or
regulations.
16. General Grading. If general grading was conducted to facilitate pipeline construction, these materials·
will be replaced and graded to recreate the preconstruction topography.
Final Reclamation:
17. Cleanup. Cleanup activities will be initiated as soon as practicable after backfilling activities have
been completed. All construction-related debris will be removed and disposed of at an approved
disposal facility.
18. Subsoil and Topsoil Placement. Subsoil will be evenly re-contoured across the right-of-way to
pre-construction conditions. After the subsoil has been re-spread the contractor·willspreactthe
previously segregated topsoil back across the right-of-way. The topsoil will be evenly spread to
original contours.
19. Vegetation. After any remaining topsoil is spread, the vegetative seed mix will be applied. The area
will be revegetated according to private landowner Surface Use Agreements and/or according to the
BLM/Forest Service reclamation requirements. Details for revegetation are provided within the BMP
Manual (discussed in Section 3.3) and the Revegetation Manual (provided as Appendix B).
20. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage
crossings) additional measures may be applied to increase stability of the reclaimed area. Possible
erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3): Actual
locations and measures used are shown on the Site Plans, which are kept with the Site Specific
Records (Volume 2 of the Master SWMP).
2.1.3 Compressor Stations, Treatment Facilities, or Other Facilities.
Construction activities for compressor stations, treatment facilities, and other facilities are generally completed
in the following sequence:
Preconstruction:
1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated.
2. Temporary BM P's. Where physical access is available, installation of terminal perimeter and
temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs
used for each site are shown on the Site Plans, which are kept with the Site Specific Records
(Volume 2 of the Master SWMP).
Construction:
3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the
terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any
run-on-protection discharge points, and/or chipped or other depending on landowner requirements.
4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling,
2-4 Revised June 2009
diversion are to be placed for ROP to prevent the greater landscape from discharging onto the
planned disturbance. Temporary sediment control BM P's shall be placed at the discharge points of
the ROP until permanent erosion controls can be installed along the entire length of the ROP.
Diversions are to be installed along the terminal discharge edge inside of the vegetation windrows
to convey site water/sediment to terminal discharge points where rough retention reservoirs are to
be installed. The retention reservoir outlets are to receive temporary sediment control BM P's until
permanent retention reservoirs and erosion, drainage, and sediment BMP's can be installed.
5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are
to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil
stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess
is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major
earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be
identified for immediate interim reclamation shall receive topsoil.
6. General Rough Grading. The site location will be graded to provide suitable surfaces for building
sites and vehicle traffic, and may be graded to establish surface drainage·patterns, such as· berms or
roadside ditches as necessary.
7. Excavation. Soil will be excavated to allow for the construction of foundations. Trenches will be
excavated for all underground piping and conduit. Excess soil will typically be used in general site
grading.
8. Foundation Construction. Foundations will be constructed lo support facility buildings. Foundations
may consist of select backfill, concrete spread footings, piles, etc. Finished support elevations are to
be installed according to engineered drawings or twelve to eighteen inches (12-18") above finished
grade or the lowest point of the facility.
9. Facility Construction. Buildings, tanks, processing equipment, etc. will be constructed. Utilities will
be installed.

will generally be reclaimed. Salvaged topsoil will be spread and the vegetative seed mix will be
applied.
13. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage
crossings) additional measures may be applied to increase stability of the reclaimed area. Possible
erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual
locations and measures used are shown on the Srte Plans, which are keptwrth the Site· Specific
Records (Volume 2 of the Master SWMP).
Final Reclamation:
14. Reclamation of Closed Facilities. When facilities are no longer necessary, the buildings may be
demolished, according to approved procedures. All construction materials will be removed and the
newly disturbed areas will be reclaimed. Any remaining topsoil will be spread and the vegetative seed
mix will be applied. This may occur after termination of this permit and under the coverage of a new
construction permit.

the ROP until permanent erosion controls can .be installed along the entire length of the ROP.
Diversions may be installed along the terminal discharge edge inside of the vegetation windrows to
convey site water/sediment to terminal discharge points where rough retention reservoirs are to be
installed. The retention reservoir outlets may receive temporary sediment control BMPs until
permanent retention reservoirs and erosion, drainage, and sediment BMPs can be installed.
5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are
to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil

erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual
locations and measures used are shown on the Site Plans, which are kept with the Site Specific
Records (Volume 2 of the Master SWMP).
Final Reclamation:
11. Reclamation of Post-Operation Areas. When operation of man camp or helicopter pad is no longer
necessary, the area may be decommissioned and all newly disturbed areas will be reclaimed. Any
remaining topsoil will be spread and the vegetative seed mix will be applied. This may occur after
termination of this permit and under the coverage of a new constnxtion permit.
2.2 Area Estimates
The total Permit Coverage Area is estimated to be approximately 95,000 Acres. The area that will undergo
clearing, excavation, and/or grading is estimated to be approximately 800 acres. Because the area will vary
2-6 Revised June 2009
over time, these are only approximate estimates. This information is used to help determine the extent of
control measures (BMPs) needed.
2.3 Description of Existing Topography and Soils
The Permit Coverage Area consists of two climatic zones and are referred to as the Upper and Middle Zones.
The Upper Zone exists at elevations between 7,500 to 8,500 feet ASL; excluding southern facing slopes
greater than 20%. Annual precipitation within this zone ranges from 16 to 25 inches annually. The soils within
the Upper Zone are primarily loam textured soils within the Parachute-Rhone-lrigul series. These soils are
mostly well drained, cool soils with dark-colored organic-rich surface layers derived from shale and sandstone.
Soil textures above the rim are generally loam with loam to clay loam sub-soils and range in depth from <20"
on ridges to >60" in swales. All of the upland soils above the rim are in low to medium erosion classes.
The Middle Zone exists at elevations between 7,500 to 6,000 feet ASL; including southern facing slopes
greater than 20%. Annual precipitation within this zone ranges from 13 to 14 inches annually. The area below
the rim encompassing the cliffs, talus and steep colluvial slope at the base of the cliffs are derived from the
Green River shale. Below the cliffs and talus is a zone of soils formed from colluvium and Wasatch
Formations. Soils are shallow, poorly developed and there are many rock outcrops and badlands. Badlands
are steep, nearly barren areas dissected by many ephemeral drainages. Soils on the upper slopes of this zone
have a thin, organic-rich surface layer and little development of soil horizons. Soils on lower slopes are shallow
to moderately deep and are well-drained. Surface texture is loam, clay loam, or silty clay loam with variable
amounts of gravel, cobbles and boulders, talus slopes and colluvial slopes below rock outcrops. Soils are
moderate to highly alkaline. Sub-soils usually have higher clay conter1t and. are calcareous. Erosion hazard is.
usually severe.
A map and table summarizing the existing soils within the Permit Coverage Area (including permeability,
available water capacity, surface runoff, and erosion hazard of those soils) are provided in Appendix C.
2.4 Description of Existing Vegetation
The existing percent vegetative ground cover for each well pad, section of roadway/pipeline, etc. withirr the
Permit Coverage Area is estimated on each inspection and maintenance report form (discussed in Section
5.4), which are kept with the Site Specific Records (Volume 2 of the MasterSWMP). A map indicating the
existing ecosystem types within the Permit Coverage Area is provided in Appendix C.
A description of the existing vegetation within each ecosystem (Mutel, 1992) is as follows:

Urban Areas. Urban areas contain an increased density of human-created structures in comparison to
the areas surrounding it. Depending on the area, vegetation may account for anywhere between 20 and
70 percent of the total land cover, with the remaining portion being constructed materials. Types of
vegetation within urban areas may be any combination of the above ecosystems, and may include areas
of blue grass yards and parks.
Cropland. Cropland vegetation may consist of wheat, corn, soybeans, or a variety of many other crops.
Cropland may either lie fallow (bare of any crops) or contain crops at any stage of growth from seedlings
to mature plants.
2.5 Identification of Potential Pollution Sources
Potential sources of pollution are associated with all phases ofthe project from the start of construction !hough
interim reclamation and up until final stabilization has occurred. Final stabilization occurs when construction
activities have been completed and all disturbed areas. have been either built on, paved, or a uniform
vegetative cover has been established with a density of at least 70 percent of pre-disturbance levels, or
equivalent permanent, physical erosion reduction. methods have been employed ..
The most common source of pollution during construction is sediment resulting from the erosion of recently
cleared and/or graded areas, such as cuVfill slopes and soil stockpiles. However, there may be many potential
pollution sources at any given site. The following types of conditions that might affect the potential for a
pollutant source to contribute pollutants to stormwater (CDPHE,. 20078) shall be evaluated:
• The frequency of the activity (i.e., does it occur every day or just once a month? can it be scheduled to
occur only during dry weather?);
• Characteristics of the area where the activity .. takes place (i.e., surface type (pavement, gra11el,
vegetation, etc.), physical characteristics (site gradients, slope lengths, etc.));
• Ability of primary and secondary containment (fuel tanks, drum storage, etc.) at product storage and
loading/unloading facilities to prevent and contain spills and leaks;
• Proximity of product storage and loading/unloading facilities to waterways or drainage facilities;
• Concentration and toxicity of materials which may. to be found in the site's stormwater runoff; and
• Contamination of storage facilities/containment with stored materials (i.e., used oil drums or tanks
coated with spilled oil).
The following items are potential sources of pollutants at the North Parachute Ranch. Each of the potential
sources of pollutants will be controlled using one or more of the following types of BMPs: Erosion Controls,
Drainage Controls, Sediment Controls or Non-Stormwater Controls. Descriptions and details for each of these
types of BMPs are provided in the BMP Manual (discussed in Section 3.3). Actual BMPs used at each site are
shown on the Site Plans (discussed in Section 5.4).
Construction:
• All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls.
• Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls.
• Management of Contaminated Soils: Non-Stormwater Controls.
2-9 Revised June 2009
• Loading and Unloading Operations: Non-Stormwater Controls.
• Outdoor Storage Activities (Building Materials, Fertilizers, Chemicals, etc.): Non-Stormwater Controls.
• Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls.
• Significant Dust or Particulate Generating Processes: Non-Stormwater Controls.
• Routine Maintenance Activities Involving Fertilizers, Pesticides, Detergents, Fuels, Solvents, Oils, etc.:
Non-Stormwater Controls.
• On-Site Waste Management Practices (Waste Piles, Liquid Wastes, Dumpsters, etc.):
Non-Stormwater Controls.
• Concrete Truck/Equipment Washing, Including the Concrete Truck Chute and Associated Fixtures
and Equipment: Non-Stormwater Controls.
• Dedicated Asphalt and Concrete Batch Plants: There will be no asphalt or concrete batch plants
located within the Permit Coverage Area of this SWMP.
• Non-Industrial Waste Sources Such as Worker Trash and Portable Toilets: Non-Stormwater Controls.
Interim/Final Reclamation:
• All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls.
• Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls.
• Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls.
• Significant Dust or Particulate Generating Processes: Non-Stormwater Controls.
• Non-Industrial Waste Sources such as Worker Trash and Portable Toilets: Non-Stormwater Controls.
2.6 Allowable Sources of Non-Stormwater Discharge
Allowable sources of non-stormwater discharge within the Permit Coverage Area ihcrude the fatrowihg:
• Uncontaminated Springs. Although there are several springs within the Permit Coverage Area,
None of these springs are currently located in areas where soil disturbance will occur. If this changes
in the future, the controls used at any such location will -Oe noted in the Site Specific Records. (Volume ..
2)
• Landscape Irrigation Return Flow. There are several locations in the Lower Zone where pipelines
are within irrigated fields. These locations will be treated similarly to any water crossing with the use of
an appropriate control which will be noted in the Site Specific Records.
• Construction Dewatering. Construction dewatering is described and.discussed. it\ Section 3.2.5 ....
• Concrete Washout. Concrete washout is described and discussed in Section 3.2.4.
• Emergency Fire Fighting Water. Water used to put"out any type of-fire is considered an allowable
source of non-stormwater discharge.
No other non-stormwater discharges are allowed under· !he Stormwater Constwction Permit. Ot~er types ol
non-stormwater discharges must be addressed in a separate permit issued for that discharge.
2.7 Receiving Water
Runoff from disturbed areas during construction will be controlled and/or routed through the use of one or
more BMPs, as described later in this plan, prior to being discharged to receiving waters. However, it may be
expected that runoff from certain areas will infiltrate into the earth and is not expected to contribute to receiving
waters.
2-10 Revised June 2009
In general, runoff from the Permit Coverage Area comes from springs and tributaries that lead to three different
forks. West Fork will flow east to south east; Middle Fork will flow south to south east and East Fork will flow
west to south east. All tributaries will flow to Parachute Creek and then in to the Colorado River.
2.8 Master SWMP Permit Area Map and Individual Stormwater Site Plans
An overall Master SWMP Permit Area Map is provided as Appendix D. This map is likely to change constantly
and will be updated at least annually. The Master SWMP Permit Area Map includes:
• Contours and elevations (topography) with existing drainage patterns;
• Locations and names of major surface waters such as streams, wetlands, irrigation ditches, canals,
etc ... ;
• Master SWMP permit area boundaries; and
• Construction area locations including roads, pipelines, well pads,. compressor station facilities;
treatment facilities, water parks, and all other facilities.
Individual Stormwater Site Plans (Site Plans) of each site (well pad, access road, section of pipeline, etc.) are
provided with the Site Specific Records (Volume 2 of the Master SWMP). Separate Site Plans will be
developed for each phase of construction: preconstruction, construction, interim reclamation (if applicable),
final stabilization (if applicable) and final reclamation (if applicable). These Site Plans include:
• Construction site boundaries (this is the area expected to be disturbed by clearing, excavating,
grading, or other construction activities);
• Contours and elevations (topography) with existing and proposed drainage patterns;
• Limits of well pads and locations of reserve pits and well heads (if applicable);
• All areas of ground surface disturbance, including areas a! cut and fill;
• Locations of all potential pollutant sources listed in Section 2.5 (including areas used for vehicle
fueling, the storage of materials, equipment, soil, or waste; etc ... );
• Locations of all minor surface waters and all anticipated allowable sources of non-stormwater
discharge (including springs, dewatering, concrete washout, etc ... );
• Locations of all existing and planned BMPs (including erosion, drainage, and sediment controls);
• Locations, names, and distances to streams, wetlands, irrigation ditches, canals, and other surface
waters; and
• The size, type and location of any outfall(s). If the stormwater discharge is to a municipal separate
stormwater system, name that system, the location of the storm sewer discharge, and the ultimate
receiving water(s).
Figures showing typical BMP locations along roadways and pipelines are provided as part of the BMP Manual
(discussed in Section 3.3)
2-11 Revised June 2009
3.0 Best Management Practices (BMPs)
A key component of this Master SWMP is employing BMPs to improve stormwater quality. Local factors will
be evaluated to determine what BMPs are suitable and practical at different locations. BMPs will be employed
in different combinations during construction activities and phases as conditions warrant. Due to the fact that
this Master SWMP is likely to cover more than one ecosystem (as described in Section 2.4), the selection of
BMPs (including type, quantity, sequence/combination, etc.) will vary at each site within the Master SWMP
Permit Area. Specific BMPs to be employed at each well pad, road, pipeline, or other facility are identified on
the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP).
3.1 Erosion, Drainage, and Sediment Control BMPs
The primary method for controlling erosion, drainage, and sediment transport consists of minimizing initial
disturbance of the soil and ground cover. However, many other methods can also be used. All stormwater-
related BMPs will fall under at least one of the following three types of controls:
• Erosion Control. Any source control practice that protects the soil surface and/or strengthens the
subsurface in order to prevent soil particles from being detached by rain or wind, thus controlling
raindrop, sheet, and/or rill erosion.
• Runoff Control. Any practice that reduces or eliminates gully, channel, and stream erosion by
minimizing, diverting, or conveying runoff.
• Sediment Control. Any practice that traps the soil particles after they have been detached and
moved by wind or water. Sediment control measures are usually passive systems that rely on
filtering or settling the particles out of the water or wind that is transporting them prior to leaving
the site boundary.
BMPs may also be classified as either structural or non-structural controls:
• Structural Control. Handles sediment-laden stormwater prior to it leaving each site. Structural
BMPs are used to delay, capture, store, treat, or infiltrate stormwater runoff Some examples of
structural BMPs include sediment traps, diversions, and silt fences. Most Runoff Controls and
Sediment Controls can also be classified as Structural Controls.
• Non-structural Control. Reduces the generation and accumulation of pollutants, including sediment,
from a construction site by stabilizing disturbed areas and preventing the occurrence of erosion.
Some examples of non-structural BMPs include. revegetation, mulching, and surface roughening.
These types of stabilization techniques are not only the most effective method for reducing soil loss,
but they are also normally the most cost effective due to low initial cost and reduced maintenance
requirements. Most, but not all, Erosion Contmls cafi also be olassilied as Non-structYraf Controls.
The Site Plans, as mentioned previously and kept with the Site Specific Records (Volume 2 of the Master
SWMP), show the proposed locations of all erosion, drainage,.afld sedimefllcontml.BMPs (both stru.ctural and
non-structural). Detailed descriptions, design criteria, construction specifications, and maintenance
information for all BMPs are provided in the BMP Manual (discussed in Section 3.3).
3.2 Non-Stormwater Control BMPs
Non-stormwater controls include general site and materials management measures that indirectly aid in the
minimization of water pollution. Types of pollution sources include, but are not limited to, litter, oil and grease,
hazardous material spills, and sediment.
3-1 Revised June 2009
3.2.1 Materials Delivery and Storage
The good housekeeping practices listed below will be followed on site during construction and operation:
• An effort will be made to store only enough product required for task completion.
• All materials stored on site will be stored in a neat and orderly manner in appropriate containers and,
where possible, under a roof or other enclosure, and/or within secondary containment areas to avoid
contact with stormwater.
• Products will be kept in their original containers with the original manufacturer's label.
• Substances will not be mixed with one another unless recommended by the manufacturer.
• Whenever possible, all of the product will be used before disposing of the container.
• Manufacturer's recommendations for proper use and disposal will be followed.
Additional information on material delivery and storage is available in the BMP Manual (discussed in
Section 3.3).
3.2.2 Material Handling and Spill Prevention
In addition to the material storage practices (listed in the previous section) that will be used to reduce the risk
of spills or other accidental exposure of materials and substance, the BMP Manual (discussed in Section 3.3)
will provide more detailed information on spill prevention and control. Furthermore, the Spill Prevention,
Control and Countermeasure (SPCC) Plan will be followed for the control of hydrocarbons. h> general, spill
prevention and response procedures will include notification (CDPHE 24-hour spill reporting line-877-518-
5608), clean-up with the use of spill kits and absorbents, and ensuring that materials and wash water can not
discharge from the site, and never into a storm drain system or stream.
3.2.3 Vehicle Cleaning, Fueling, Maintenance, and Tracking Controls··
As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting
companies and/or vendors are required to service all vehicles and equipment prior to entering EnCana
facilities. However, in the event maintenance procedures are required at EnCana facilities, all fluids
transferred must utilize secondary containment and drip pans to minimize a releaseotmateriats amt· properly
dispose or recycle spent materials in compliance with local, state, and federal guidelines.
While on site, equipment will be parked, serviced, and fueled within designated areas. Equipment fueling on
pipeline rights-of-way will be completed where necessary during active construction. Periodic inspections of
equipment and control procedures will be implemented. Selected equipment may be fueled in place using fuel
trucks. When necessary, equipment and machinery will be decontaminated at an on-site decontamination
area prior to removal from the construction area. Areas will be provided with adequate waste disposal
receptacles for liquid as well as solid waste.
Vehicle tracking of sediments is not expected to be a problem due to construction scheduling. Construction
vehicles will remain on site throughout earth-moving activities. All other vehicles remain in stabilized areas
and do not enter the construction area until that .area is stabilized. However, applicable BMPs (such as
scheduling (lo minimize site access), stabilized construction entrances, vehicle cleaning, etc.) will be utilized if
sediment tracking does become a problem.
In addition to the typical practices listed above, the BMP Manual (discussed in Section 3:3) provides more
detailed information on vehicle cleaning, fueling, maintenance, and tracking controls.
3.2.4 Waste Management and Disposal
As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting
companies and/or vendors are required to manage all waste generated by their activities at EnCana facilities in
3-2 Revised June 2009
compliance with local, state, and federal guidelines. EnCana Oil & Gas (USA) utilizes a periodic inspection
program to ensure waste management requirements are fulfilled and inspections are documented.
A few of the waste management procedures that will be followed include the following:
• Proper bins will be provided for trash collection and disposal in compliance with local, state, and
federal guidelines.
• Contaminated soils will be placed into a lined and bermed area. Samples of the impacted soil will be
collected and a complete characterization analysis will be performed. When applicable, the impacted
soil will be sent to a licensed disposal facility.
• The contractor will provide portable toilets. Sanitary waste will be regularly collected by a licensed
sanitary waste management contractor and disposed of in an approved manner.
• In the event that sediment is inadvertently transported off the construction site, it will be collected and
returned to the site and placed on the soil stockpile or spread over the construction pad area and
compacted.
On well pads and access roads concrete washout is used as an interior conductor pipe ballast. Concrete
washout water can NOT be discharged to surface waters or to storm sewer systems·without separate permit
coverage. However, discharge to the ground of concrete washout water from washing of tools and concrete
mixer chutes may be authorized by this permit, provided that (CDPHE, 2007a):
1. The source is identified in the SWMP;
2. BMPs are included in the SWMP to prevent pollution of groundwater; and
3. These discharges do not leave the site as surface runoff or to surface waters.
Locations where concrete washout activities take place are shown on the Site Plans.
Additional waste management procedures, including solid waste, hazardous waste, contaminated soil,
concrete washout, and septic and sanitary waste, are included in the BMP Manual (discussed in Section 3.3).
3.2.5 Dewatering
Dewatering refers to the mechanical removal of water from an excavation or other structure. Both
groundwater and stormwater may require dewatering during construction. Dewatering of pipelines at the
completion of hydrostatic testing will be required for most pipeline installations.
3.2.5.1 Groundwater Dewatering
Groundwater is very rarely encountered during the construction activities associated with either E&P sites or
Midstream Services. If groundwater is encountered~ it is typically during construction of a pipeline· across a
stream crossing. These pipelines are either bored under the stream or a flume is utilized.
Non-stormwater construction dewatering of groundwater can· NOT be discharged to surface-waters-or to storm ..
sewer systems without separate permit coverage. However, discharges to the ground of water from
construction dewatering activities may be authorized by this permit, provided that (CDPHE, 2007a):
1. The source is groundwater and/or groundwater combined with stormwater that does not contain
pollutants in concentrations exceeding the State groundwater standards in Regulations 5 CCR 1002-
41and42;
2. The source is identified in the SWMP;
3-3 Revised June 2009
3. BMPs are included in the SWMP; and
4. These discharges do not leave the site as surface runoff or to surface waters.
Dewatered groundwater shall be pumped or diverted to a sediment control BMP prior to discharge to the
ground. Locations of groundwater dewatering, as well as any BMPs utilized, will be noted on the Site Plans as
soon as such dewatering occurs. Additional information on groundwater dewatering is provided in the BMP
Manual, discussed in Section 3.3.
3.2.5.2 Stormwater Dewatering
The discharge of pumped stormwater (not including groundwater or other non-stormwater sources) from
excavations, ponds, depressions, etc., to surface water, or to a municipal separate storm-sewer system is·
allowed by the Stormwater Construction Permit, as long as the dewatering activity and associated BMPs are
identified in the SWMP (including location of the activity), and BMPs are implemented in accordance with the
BMP Manual, discussed in Section 3.3 (CDPHE, 2007c).
Stormwater that collects in open depressions or trenches during construction activities will be dewatered into
an existing sediment control, such as a detention pond, a sediment trap, or simply into a well-vegetated area to
percolate into the ground and catch suspended sediment. The quality, source, and location of dewatering, as
well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional
information on stormwater dewatering is provided in the BMP Manual, discussed in Section 3.3.
3.2.5.3 Pipeline Dewatering
New Department of Transportation (DOT) pipelines are hydrostatically tested with water upon completion of
construction. Once the hydrostatic testing has been completed, dewatering of the pipeline must occur. This
will involve the insertion of a displacer, commonly referred to as a pig, in the pipeline. The discharge rate will
be regulated, and energy dissipation devices, and/or sediment controls will be used, as necessary, to prevent
erosion, streambed scour, suspension of sediments, or excessive stream flow. Locations on pipeline
dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs.
Additional information on stormwater dewatering is prnvided in the BMP Manual, discussed in Section 3.3.
3.3 Stormwater Manual of BMPs
A Stormwater Manual of Best Management Practices (BMP Manual) is provided as Appendix E. The BMP
Manual has been prepared to provide EnCana personnel, contractors, and subcontractors with information on
the proper selection, design, installation, and maintenance of BMPs to manage oil and gas related stormwater
and to meet federal and state SWMP implementation requirements. The main objectives of the BMP manual
are to:
• Serve as an easy-to-use guide for selecting, designing, installing, and maintaining BMPs.
• Function as a reference for construction plans and specifications.
• Ultimately lead to the avoidance of any net increase in off-site erosion and sedimentation of waters of
the U.S.
The BMPs within this BMP Manual are organized into four main types of controls for easy reference: Erosion
Controls, Runoff Controls, Sediment Controls, and Non-stormwater Controls. Each of these types of controls
has been discussed earlier in this section of the SWMP.
3.4 Phased BMP Implementation
Various BMPs will be implemented and maintained during different phases of the project. A description of
each phase is as follows:
3-4 Revised June 2009
• Preconstruction. The preconstruction phase involves the installation of BMPs (temporary and/or
permanent) around each site perimeter and at discharge points (such as vegetation buffers (no
installation required for this BMP), slash, wattles, diversions, sediment basins and reservoirs, etc ... ).
• Construction. The construction phase involves the stripping and stockpiling of topsoil, the excavation
and backfill for access roads, pipelines, and well pads, and the installation of additional BMPs
(preferably permanent BMPs) to control erosion and sedimentation (such as tracking topsoil piles and
the installation of roadside channels, culverts, diversions, etc ... ).
• Interim Reclamation. The interim reclamation phase primarily involves seeding of all disturbed areas
not needed during operation of the well pads. However, this phase also involves the installation of any
additional permanent BMPs that may be needed, as well as the continued maintenance and
inspections of all BMPs until final stabilization occurs. Final stabilization occurs once all surfaces are
built on, paved or graveled, and/or a uniform stabilized vegetative cover with a density of 70 percent of
pre-disturbance levels has been established or when an equivalent permanent, physical erosion
reduction method has been employed. A further explanation of final stabilization is provided as
section 4 of this plan.
• Final Reclamation. For pipelines, this phase involves seeding of all disturbed areas, and the
installation of any additional permanent BMPs that may be needed, as well as the continued
maintenance and inspections of all BMPs until final stabilization occurs: For other areas (roads, well
pads, facilities, etc ... ), this phase {which may occur after termination of this permit and under the
coverage of a new construction permit) occurs when operation of the area is no longer necessary. In
these cases, this phase will include the installation of any additional BMPs required during facility
decommissioning as well as the spreading of any remaining topsoil, the application of seed, and the
inspection/maintenance of all BMPs until final stabilization occurs.
Temporary controls, such as silt fencing, may be used to control sediment and erosion during preconstruction
and construction activities. Permanent controls, such as diversions and sediment traps, may also be used
during the initial phases of the project. However, only permanent _controls will be used during interim
reclamation and final stabilization. Temporary controls may be converted into permanent controls (such as
revegetating a diversion) if needed. The primary control used during interim and final stabilization will be
revegetation. Seeding will occur as soon as possible after disturbance of an area is complete. If the seeding
is not successful, the area will either be reseeded or other controls will be put in place until reseeding can
occur.
3-5 Revised June 2009
4.0 Interim Reclamation and Final Stabilization
As soon as practicable after construction activities have been completed in a disturbed area, interim (for well
pads, or other facilities) or final (for roads and pipelines) reclamation will be started to prevent further erosion
of soil from that area. This typically occurs immediately upon completion of earthwork activities. All disturbed
areas (except for the surface of dirt roads, those portions covered by pavement or a structure, and those areas
used during operation of a well) will be stabilized with permanent controls. The most common measure used
to achieve final stabilization is revegetation. Mulching, erosion control blankets, surfacing with gravel or slash,
and/or other methods may also be used. Structural controls (such as diversions, berms, and sediment traps)
may be revegetated and used as permanent measures to control pollutants in stormwater discharges that will
occur after construction operations have been completed. Appendix E includes detailed information on each
of the previously discussed BMPs. In addition, a revegetation manual is provided as Appendix B, which
provides guidance as to possible methods and materials needed to accomplish revegetation on differing site
conditions. The specific BMPs used at each site are shown on the Site Plans which are kept with the Site
Specific Records (Volume 2 of the Master SWMP).
Final stabilization means that all ground surface disturbing activities at the site have been completed, and all
disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an
individual plant density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical
erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative
cover capable of providing erosion control equivalent to pre-existing conditions at the site will be considered
final stabilization. Areas developed as stabilized unpavedsurfaces·as needed for operatiorr of the facility· after
interim reclamation, will also qualify as "finally stabilized." This includes dirt road surfaces and the portions of
the well pad surfaces that cannot be revegetated due to op.eratlonal necessity, but does not include slopes,
ditches, and other areas where revegetation is necessary. Stabilized unpaved surfaces will be prepared in
such a way as to prevent ongoing erosion issues.
Coverage under the Stormwater Construction Permit may be inactivated for any individual site or a
portion/section of that site (i.e. the access road to a well pad) when the area has attained final stabilization and
all temporary erosion and sediment control measures associated with that area have been removed. An area
will be considered finally stabilized when construction and interim reclamation is complete and when the above
final stabilization criteria have been met, even though the site may be disturbed again in the future for final
reclamation. However, future land disturbances that follow final stabilization and result in disturbance of one
acre or greater (such as final reclamation) will require new permit coverage at that time.
Upon final stabilization of any site or portion/section of a site, a signed certification sheet (provided in
Appendix F) will be placed into the Site Specific Records binder to replace the Site Plans and the inspection
and maintenance records for that area. However, the Site Plans and inspection reports shall be retained in a ·
separate location for a period of three years following final stabilization of the Permit Coverage Area. These
documents will be made available to WQCD or EPA upon request and at the time of inspection.
4-1 Revised June 2009
5.0 Inspection and Maintenance
Inspections and maintenance is an extremely important part of the Stormwater Construction Permit.
The Construction Manager will ensure that all stormwater management controls are constructed or applied in
accordance with governing specifications or good engineering practices. Experienced teams will be used for
construction. A first inspection will occur upon installation of the controls. In addition, all workers on the site
will be trained as to the location and use of the controls, especially those controls that will be disturbed as
construcf1on proceeds across the site. The goal is to minimize the potential for inadvertent removal or
disturbance of BMPs and to prevent the off site transport of sediment and other pollutants.
5.1 Inspection Schedule
Inspections are required as soon as the first soil disturbance occurs at the site. Once final stabilization of the
site has occurred and the EnCana inspector has filled out the final stabilization certification sheet (see Section
4), inspections are no longer necessary. Specific information regarding inspection schedules are provided in
the following sections.
5.1.1 Minimum Inspection Schedule for active sites
The minimum inspection schedule applies to those sites under active construction, which includes the period
from when the ground is initially disturbed to when construction activity is completed, and also includes the
preparation of areas that will be revegetated for interim reclamation. During the Active Site period, a thorough
inspection of the site stormwater management system (which includes all utilized BMPs) must be conducted at
least every 14 calendar days. Also, post-storm event inspections must be conducted within 24 hours after the
end of any precipitation or snowmelt event that causes surface erosion.
There are three exceptions to the minimum inspection schedule which are described in detail within the next
three sections: post-storm event inspections at temporarily idle sites (inspections required within 72 hours after
a storm), inspections at completed sites (inspections required monthly), and inspections during certain winter
conditions (inspections may not be required). Any use otan exception istemporary, and does not eliminate·
the requirement to perform routine maintenance due to the effects of a storm event or other conditions that
may impact BMP performance, including maintaining·vehicte tracking controtsand removing sediment from
impervious areas. Inspections, as described above, are required at all other times.
5.1.2 Post-Storm Event Inspections at Temporarily Idle Sites
Temporarily idle sites are those where there are no construction activities occurring following a storm event.
At such sites, post-storm event inspections must be conducted prior to restarting construction activities at the
site, but no later than 72 hours following the storm event, and the delay noted in-the inspection report. Routine
inspections still must be conducted at least every 14 calendar days.
5.1.3 Completed Sites
Once construction is completed and the site has been prepared for interim or final stabilization (including
completion of appropriate soil preparation, amendments and stabilization practices}, the site (er porticmof the
site) is considered a Completed Site (for purposes of the stormwater permit). Note: only construction activities
that result in a disturbance of the ground surface must be completed. Construction activities that can be
conducted without disturbance of the ground surface, such as certain well completion activities, would not
prohibit a site from otherwise qualifying as a Completed Site. (Completed Sites still require permit coverage
until the final stabilization criteria have been met)
Completed Sites qualify for a reduced inspection schedule, as the potential for pollution is reduced if the site
has been adequately prepared and/or seeded. However, because slopes and other disturbed areas may not
be fully vegetated, erosion in these areas still occurs which requires maintenance activities such as regrading
5-1 Revised June 2009
and seeding of problem areas. As such, inspections must continue in order to address these situations.
During the Completed Site period, a thorough inspection of the site stormwater management system (which
included all utilized BMPs) is required at least once every month. The SWMP must be amended to indicate
those areas that will be inspected at this reduced frequency.
5.1.4 Winter Conditions Inspections Exclusion
Inspections are not required at sites where construction activities are temporarily halted, snow cover exists
over the entire site for an extended period, and melting conditions posing a risk of soil erosion do not exist.
This temporary exclusion is applicable only during the period where melting conditions do not exist, and
applies to the routine 14-day and monthly inspections, as well as the post-storm-event inspections. It is typical
that when snow cover exists, even at a Completed Site, significant potential for erosion and BMP failure exists
when melting does finally occur. Therefore, the site should prepared prior to snow cover to ensure ii is as
stabilized as possible, and be prepared to perform site maintenance when melt-off occurs, to alleviate any
potential problems. Inspection records (see Section 5.4) must document the following information when this
exclusion is used: dates when snow cover occurred, date when construction activities ceased, and date
melting conditions began.
5.2 Performing Inspections
Inspections will be conducted by qualified personnel on the following areas:
• All vegetated areas until 70% of pre-disturbance vegetation levels are reached.
• All BMP measures identified in this document.
• Construction site perimeter and discharge points.
• All disturbed areas.
• Areas used for storage of material/waste that are exposed to precipitation.
• Other areas determined to have a significant potential for stormwater pollution, such as demolition
areas or concrete washout locations, or locations where vehicles enter or exit the site.
These areas will be inspected to determine if there is evidence of, or the potential for, pollutants leaving the
construction site boundaries, entering the stormwater drainage system, or discharging to state waters. All
BMPs will be evaluated to determine if they still meet the design and operational criteria in the SWMP and if
they continue to adequately control pollutants at the site. Any BMPs not operating in accordance with
Appendix E of this SWMP will be repaired or replaced (according to the following section) and the Site Specific
Records will be updated.
5.3 Maintenance
Maintenance activities will ensure that all control measures are functioning at optimum levels and that all
procedures and techniques will be in proper working order during a runoff event or spill conditi011. Any
maintenance, repairs, or replacements deemed necessary after required inspections will be corrected as soon
as possible (if not immediately), to minimize the discharge of pollutants. Certain maintenance procedures may
take a short period of time to make sure that all the-propeF safely precaulionsare in place, such as.a "one call"
for utilities, if the maintenance involves excavation of sediment located above a buried pipeline.
Maintenance will include, but is not limited to:
• Pickup or otherwise prevention of litter, construction debris, and construction chemicals from
becoming a pollutant source prior to anticipated storm events.
• Removal of sediment from silt fences, sediment traps, and other sediment controls.
• Reseeding of any bare spots where vegetation has failed to establish.
5-2 Revised June 2009
• Repairs and/or adjustments to any erosion and sediment control that is deteriorating or found to be
performing inadequately.
Detailed maintenance requirements for each BMP are identified in Appendix E.
When maintenance is required, the following process will typically be followed:
1. Perform inspections according to the minimum inspection schedule discussed in Section 5.1.
2. Note the need for maintenance on the inspection and maintenance report form.
3. If necessary, collect the additional materials and/or resources needed to perform the maintenance
activity.
4. Perform maintenance and note the date performed on the inspection and. maintenance report form.
5. Re-inspect the area to ensure compliance.
5.4 Documenting Inspections and Maintenance
The permittee must document inspection results, maintenance activities, and maintain a record of the results
for a period of 3 years following expiration or inactivation of permit coverage. A typical inspection and
maintenance report form is provided in Appendix G. Although the site may have a phased construction
schedule, all construction areas may be inspected.at the same time and on one form. Each well pad, road,
pipeline, or other facility which is inspected shall be clearly noted on the inspection form. Inspection reports
will include the following:
• Date of inspection, name of inspector, and title of inspector
• The area inspected (Site ID), type of area (well pad, access road, pipeline, etc.), phase of construction
(preconstruction, construction, etc.), and type of inspection (active, completed, etc.)
• Site specific information including disturbed area, soil type(s), ecosystem/vegetation type(s), receiving
waters, etc.
• Vegetation observations including the percent pre-disturbance vegetation and whether or not
vegetation growth has reached 70% of pre-disturbance levels
• Specific inspection requirements (all BMPs and areas of potential pollutant sources)
• Observed conditions including:
• Location(s) of discharges of sediment or other pollutants from the site
• Location(s) of BMPs that need to be maintained
• Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular·
location
• Location(s) where additional BMPs are needed that were not in place at the time of inspection
• Description and date(s) of corrective action(s) taken, and measures taken to prevent future violations
• Changes necessary to the SWMP
A hand drawn Site Plan shall be included, if necessary, to show the location(s) of any observed condition (as
listed above).
After adequate corrective action(s) has been taken and recorded, or where a report does not identify any
incidents requiring corrective action, the report will contain a signed statement indicating the site is in
compliance with the permit to the best of the signer's knowledge and belief.
5-3 Revised June 2009
All completed inspection and maintenance report forms (a blank copy of which is included in Appendix G) are
kept with the Site Specific Records (Volume 2 of the Master SWMP).
5-4 Revised June 2009
6.0 Plan Revisions and Retention
When BMPs or site conditions change, the Master SWMP (Volume 1) and/or the Site Specific Records
(Volume 2) will be amended to accurately reflect the actual field conditions. Examples include, but are not
limited to, removal of BMPs, identification of new potential pollutant sources, addition of BMPs, modification of
BMP installation/implementation specifications or maintenance procedures, and changes in items included in
the Site Plans. Changes to the Master SWMP (Volume 1) shall be noted on the SWMP Revisions log at the
front of this plan. Changes to individual site conditions will be noted in the Site Specific Records (Volume 2) on
the applicable inspection and maintenance report form. All changes in Volume 1 and Volume 2 shall be made
prior to actual changes in the site conditions, except for responsive SWMP changes, which shall be made
immediately after changes are made in the field or as soon as practical, but in no case more than 72 hours
after the change(s) in BMP installation and/or implementation occur at the site that require development of
materials to modify the SWMP. At a minimum, the Master SWMP will be updated annually.
The Master SWMP and the Site Specific Records will be retained at the EnCana field office in Parachute
during active construction and site inspections to ensure accurate implementation and maintenance of BMPs,
and required revisions. These documents will be retained for a period of three years following final
stabilization of the Permit Coverage Area. These reports will be made available to WQCD or EPA upon
request and at the time of inspection.
6-1 Revised June 2009
7.0 Inactivation Notice
When all disturbed areas associated with the Stormwater Construction Permit have reached "final stabilization"
(as described in Section 4), all temporary erosion and sediment control measures have been removed, and all
components of the SWMP are complete, the area no longer requires coverage under the permit terms. At that
time, EnCana will submit an Inactivation Notice that closes this permit to the WQCD upon final stabilization of
all areas covered by the permit. A blank copy of this form is included in Appendix H of this document.
Upon receipt of the Inactivation Notice, the WQCD will provide written confirmation that coverage under this
permit has been terminated. This historical documentation will be maintained at the EnCana field office in
Parachute for a period of at least three years following termination of permit coverage.
7-1 Revised June 2009
8.0 Signature
The signature page will not be signed unless the SWMP is requested by an agency as a legal document. At
that time, the supervisor will review the most updated version of the SWMP and sign it before submitting to an
agency.

Abstract
As authorized by the White River Field Office of the Bureau of Land Management
(BLM), Grand River Institute was contracted by Encana Oil and Gas (USA) Inc. to complete
a Class III (intensive) cultural resource inventory for four proposed Liberty well pad locations
(M30 495, B36 496, D36 496, and F25 496), a central distribution point (CDP J25 496) and
related linear routes (2.8 miles) in Garfield County, Colorado for Encana Oil and Gas (USA)
Inc.
The inventory was undertaken to ensure the project's compliance with state and
federal legislation governing the identification and protection of cultural resources on
privately owned lands that will be affected by a government action. The purposes of this
investigation were to identify resources within the previously unsurveyed areas likely to be
affected by the proposed action, to evaluate these sites' eligibility for listing in the National
Register of Historic Places (NRHP), and to make management recommendations for those
sites found to be eligible.
Record searches for the project area were made through the BLM and the Office of
Archaeology and Historic Preservation on August 6'h and 18'\ 2009. These indicated that a
portion of the proposed pipeline along the main ridge road had been recently inventoried
(within the last four years) and would not require inspection. Additionally, the files search
indicated that no cultural resources had been previously recorded within the project's discrete
areas.
Field work was perfonned on August 12'h and September 29'\ 2009 which resulted in
the inspection of approximately 270 acres of private land. The inventory was limited by
heavy vegetation cover and steep slopes. No cultural resources were found and no further
work is recommended. Accordingly, archaeological clearance is recommended.

Introduction
As authorized by the White River Field Office of the Bureau of Land Management
(BLM), Grand River Institute was contracted by Encana Oil and Gas (USA) Inc. to complete
a Class III (intensive) cultural resource inventory for four proposed Liberty well pad locations
(M30 495, B36 496, D36 496, and F25 496), a central distribution point (CDP J25 496) and
related linear routes (2.8 miles) in Garfield County, Colorado for Encana Oil and Gas (USA)
Inc. The inventory was conducted by Carl E. Conner (Principal Investigator), Jim Conner,
Dana Archuleta and Travis Archuleta of Grand River Institute under BLM Antiquities Permit
No. C-52775. Carl Conner and Barbara Davenport completed the final report. Field work
was performed on August 12'h and September 29'', 2009 which resulted in the inspection of
approximately 270 acres of private land.
The inventory was conducted to meet requirements of the National Environmental
Policy Act (NEPA) of 1969 (42 U.S.C. 4321), the Federal Land Policy and Management Act
of 1976 (43 U.S.C. 1701), and the Archaeological Resources Protection Act of 1979 (U.S.C.
470aa et seq., as amended). These laws are concerned with the identification, evaluation, and
protection of fragile, non-renewable evidences of human activity, occupation and endeavor
reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and
natural features that were of importance in human events. Such resources tend to be
localized and highly sensitive to disturbance.
Location of the Project Area
The survey areas are located approximately 30.0 miles southwest of Meeker in
Garfield County, Colorado. The proposed well pads, CDP site, and pipeline/access routes are
located in T. 4 S., R. 95 W., Sections 30 and 31; T. 4 S., R. 96 W., Sections 25, 34 and 36;
and T. 5 S., R. 96 W., Section 3; 6th P.M. (Figure 1).
Environment
The project's discrete areas are located adjacent to and on the Divide Road that runs
along a mountainous ridge of the Roan Plateau that divides the area drained by the Piceance
Creek on the north and Parachute Creek on the south. These areas are located within a large
northwest-southeast trending structural downwarp known as the Piceance Creek Basin, a
major geological subdivision of Colorado. Subsidence of the Basin probably began some 70
million years ago, with the onset of the Laramide Orogeny during Late Cretaceous times, and
continued until the Late Eocene (Young and Young 1977: 46). During this period of roughly
25 million years, the Basin received as much as 9000 feet ofTertiarystream and lake deposits,
all of which gently dip toward the center of the downwarp. The Tertiary-age Uintah and the
Green River Formations occur within the study area.
1
Elevations of the project areas range from about 8000 feet-to-8360 feet, which fall
within the Transitional Zone. On the ridge tops and sides, the understory is quite thick,
consisting of chokecherry, smooth maple, serviceberry, and wild rose. The higher elevation
ridges also have groves of aspen, common particularly at the heads of drainages. On the
steep slopes bordering these uplands is found the only coniferous forest type of the project
area, the Douglas fir. Its associated understory is light--predominantly snowberry,
serviceberry, and barberry. Most of the flat terrain is occupied by mountain big sage and
western snowberry. Gentle north and east-facing aspects support a mountain brush
community-Utah serviceberry, gambel oak, and snowberry. Ground cover ranges from 80 to
100 percent. Soils on ridgetops are shallow loams with intermixed shale, or fractured shale.
Away from the ridge, soils deepen and become darker and loamier.
Nineteen mammal species-among them the deer mouse, least chipmunk, short-tailed
weasel, mule deer, and black bear-and 38 bird species are known in the Douglas fir
community. Amid the aspen environment are 16 mammals-including the deer mouse,
masked shrew, least chipmunk, northern pocket gopher, montane vole, porcupine, striped
skunk, short-tailed weasel, red fox, deer, and elk-and 30 birds. The mountain brush
community attracts 37 bird species and 27 mammal species, among these the rock squirrel,
bushy-tailed woodrat, deer mouse, porcupine, least chipmunk, beaver, muskrat, raccoon,
striped skunk, coyote, red fox, and the short-tailed weasel (Union Oil Company, Energy
Mining Division 1982:Hl4-18). Present land use includes energy development, open range
for domestic animals, and modem hunting.
Climatically, the region is characterized as having a steppe-type climate. Average
annual rainfall ranges roughly between 12 and 24 inches. On the Roan Plateau at 8000 feet,
the average annual rainfall is 25.66 inches and the average annual temperature is 35.5 ° F.
(ibid.: 182, Tables K.1.5 and K.1.7). Temperatures have varied between -20 degrees F. in
winter and 90 degrees F. in summer with a frost free seasonal range of70 to 100 days.
Agriculture is limited by the low rainfall, a short period of frost-free days, and low winter
temperatures (USDA SCS 1978). Paleoenvironmental data for the area are scant, but it is
agreed that gross climatic conditions have remained fairly constant over the last 12,000
years. Still, changes in effective moisture and cooling/ warming trends probably affected the
prehistoric occupation of the area.
Summary of Files Search and Literature Overview
A literature review for known cultural resources in the project area was made through
the BLM White River Field Office and the Colorado Historical Society's Office of
Archaeology and Historic Preservation on August 6'h and 18'", 2009. These indicated that a
portion of the proposed pipeline along the main ridge road had been recently inventoried
(within the last four years) and would not require inspection. Additionally, the files search
indicated that no cultural resources had been previously recorded within the project's discrete
areas or nearby (within a mile).

Many of the prehistoric sites that were previously recorded in the Piceance Creek
Basin have been identified as open lithic scatters. All are likely to have been open camps as
there are no local lithic procurement sites in the Basin. The remains of wickiups (brush
shelters) have been identified at a relatively high number of sites in the area, and special care
was taken to assure similar sites were not overlooked as their characteristics can be subtle.
Historic site types recorded in the Basin have been cabins, herder camps, horse traps, and
brush corrals.
Local and regional archaeological studies suggest nearly continuous human
occupation of west-central Colorado for the past 12,000 years. Cultural materials identified
by these and other studies indicate human use of the region for at least 10,000 years and
include manifestations of the Paleoindian Era, big-game hunting peoples (ca. 11,500 -6400
BC); the Archaic Era hunter/gatherer groups (ca. 6500-400 BC); the Formative Era
horticulturalist/ forager cultures (ca. 400 BC-AD 1300); the Protohistoric Era pre-horse
hunter/gatherers (ca. AD 1300 -AD 1650) and early historic horse-riding nomads (ca. AD 1650
-AD 1881). An overview of the prehistory of the region is provided in a document published
by the Colorado Council of Professional Archaeologists entitled Colorado Prehistory: A
Context for the Northern Colorado Plateau (Reed and Metcalf 1999). Overviews of the
history of the region are presented in the Colorado Historical Society's publication entitled
Colorado Plateau Country Historic Context (Husband 1984), in the BLM publication Frontier
in Transition (O'Rourke 1980), and in Colorado Council of Professional Archaeologists'
Colorado History: A Context for Historical Archaeology (Church et al. 2007).
Study Objectives
The purpose of the study was to identify and record all cultural resources within the
areas of potential impact, to assess their significance and eligibility to the National Register
of Historic Places (NRHP), and to make management recommendations for those sites found
to be eligible or potentially eligible. The presence of cultural resources was considered
unlikely based on the lack of previously recorded resources in the vicinity, even though 13
cultural resource studies have been conducted within a mile of the present project areas.
5
Field Methods
A 100 percent, intensive (Class III) cultural resource survey of the proposed linear
routes (2.9 miles) was conducted by a crew of two persons who walked in parallel transects
based on the flagged lines and spaced at 15-meter intervals to cover corridors 60 meters
(-200 feet) wide. The well pads and CDP site were surveyed by walking north-south
transects spaced at 15-meter intervals to cover 40-acre blocks centered on the staked
locations. Steep slopes were contoured. A total of approximately 270 acres (200 block and
70 linear) was inspected. Crew members worked from USGS 7.5 minute series maps.
Cultural resources were sought as surface exposures and were characterized as sites or
isolated finds. Sites were defined as a discrete locus of patterned activity greater than 50
years of age and consisting of five or more prehistoric artifacts with or without features or
over 50 historic artifacts with associated features. Also, single isolated hearths with no other
associated artifacts or features were to be recorded as a site. Isolated finds were defined as
less than five artifacts without associated features. Exceptions to this definition include
historic trash dumps without associated features; a single core reduction event with a single
core and associated reduction debitage; a single pot drop, where the sherds are from a single
vessel; or, a prospector pit with/or without artifacts and no associated historic structures or
features. All cultural resources such as open camps, lithic scatters, and isolated finds were
recorded as they were encountered.
Sites were recorded using the following methods of mapping and note taking. The
basic approach to the data collection was the continuous mapping of observed artifacts and
features by recording UTM coordinates (NAD 83 Datum) using a Trimble Geo XT. Site
maps were created using corrected data and ARCMAP. Photographs were to be taken at each
site and include general views and specific artifacts or features. Field notes and photo
negatives are on file at Grand River Institute, while the photographs are submitted to the
BLM. No artifacts were collected.
Results
Few sites or isolated finds have been found in the lands surrounding the project area's
discrete units. This may be attributed to the heavy vegetation cover within the project areas.
Accordingly, similar results were expected for this project. No prehistoric or historic cultural
resources were identified.
Discussion
No prehistoric sites or isolated finds were encountered. This may best be accounted
for by the results of the "Cultural resources predictive modeling in the Piceance Basin," a
Class II inventory that was conducted by sampling 11,520 acres within a 354,680 acre area,
6
sixteen sites and eleven isolated finds were recorded (Newkirk and Roper 1982).
Importantly, the study area involved sample areas throughout the Basin and results indicate
an average density of 1 resource (site or isolated find) per 443 acres. It is apparent from this
and other studies that the density of sites decrease significantly in size and number as the
elevation and the distance to water increases. Exceptions to this are found in the access
corridors between the Piceance Basin and other lower elevations (such as Douglas Creek).
Historic Euro-American interest in the potential agricultural lands of western
Colorado (namely the Uncompahgre, Gunnison, Colorado, Dolores, San Miguel, White, and
La Plata River valleys) had been growing for some time prior to the Utes' banishment, and by
the spring of 1881 frontier towns closest to the Ute lands were "crowded with people,
anxious to enter the Reservation and take possession of the most desirable locations (Haskell
1886:2)." Only days after the last of the Utes had been expelled, settlers began rushing onto
the reservation lands. Settlement activity spread quickly--during the autumn months of 1881
land claims were staked, townsites were chosen, and railroad routes were surveyed (Haskell
1886, Borland 1952). However, because the former reservation lands were not officially
declared public lands until August 1882, the first year of settlement activity was marked by a
degree of uncertainty regarding the legality of land claims. When finally announced, the
1882 declaration did not allow homestead entries on the newly opened lands, but only
preemptions, or cash entries, at the rate of$1.25 per acre for agricultural land, $5.00 per acre
for mineral land (Borland 1952:75). By 1895, the major portion of the land in the area had
been claimed, mostly under Cash Entry patents.
Management Recommendations
The eligibility determination and consultation process is guided by Section 106 of the
NHPA (36 CFR 60, 63, and 800). BLM actions cannot be authorized until the Section 106
process is completed (36 CFR 800.3). An inventory such as this is the first step in the
Section 106 process. As part of this first step, sites evaluated as "field eligible" or "field
need data" (unofficial evaluations) are assessed in terms of professional discretionary
observations concerning the probable effect due to the proposed action. Final determinations
of National Register eligibility and effect are made by the controlling federal agencies in
consultation with the State Historic Preservation Officer.
The 40-acre blocks inventoried for the well pads and CDP site and the 200-foot-wide
corridors inspected for the proposed pipeline/access routes contained no significant cultural
resources. The inventory was limited by heavy vegetation cover and steep slopes. No further
work is recommended. Accordingly, archaeological clearance is recommended.

1.0 INTRODUCTION
1.1 Project Description
EnCana Oil & Gas (USA) Inc. (EnCana) has requested WestWater Engineering (WWE) to
complete a "Wildlife Impact and Sensitive Areas Report" for a proposed natural gas
development project in Garfield County, Colorado. The project is located approximately 20.6
miles northwest of Rifle, Colorado. Project development will take place in Sections 24, 25, 26,
34, 35, and 36 of Township 4 South, Range 96 West (Figure I).
Construction will occur entirely on private land within EnCana's North Parachute Ranch. The
project site is accessible by both the Cow Creek Road and Sprague Gulch Road from Rio Blanco
County Road 5.
The primary use of the site and surrounding area is rangeland, wildlife habitat, and natural gas
extraction and development.
1.2 General Snrvey Information
The data used for developing the following report was collected by WWE biologists through
field surveys and assessments of wildlife, wildlife habitats, and habitats for sensitive plant
species within the proposed project area over the past several years. WWE conducted raptor
surveys in the area in the summer of2009. Broad surveys conducted on the site evaluated the
wildlife and sensitive plant species that may occupy the project area at various periods of the
year which would potentially be impacted as a result of construction and operation of natural gas
facilities. Cultural surveys were conducted by Grand River Institute, and are the subject of a
separate report held by EnCana.
Factors considered include: 1) soil type and texture; 2) existing land management; 3) absence or
presence of wildlife and plant species including raptors, sage-grouse, and other sensitive birds
species; 4) special designations by Federal and State wildlife agencies; 5) the existing natural
vegetation community, and 6) wetlands or regulated waterways potentially within the jurisdiction
of the U.S. Army Corps of Engineers (ACOE). This report provides written documentation that
describes survey findings as well as recommended mitigation measures.
2.0 LANDSCAPE SETTING
2.1 Vegetation
The vegetation at the elevation of the project area is dominated by a mixture of mountain big
sagebrush (Artemisia tridentata var. vaseyana), Gambel oak (Quercus gambelii), serviceberry
(Amelanchier alnifolia), antelope bitterbrush (Purshia tridentata), snowberry (Symphoricarpos
rotundifolius), aspen (Populus tremu/oides), and Douglas-fir (Pseudotsuga menziesii). Groves of
aspen and Douglas-fir prefer northern exposures where temperatures and soil moisture are most
suitable.
