1. INTRODUCTION
This Plan of Development (POD) describes measures to be taken by the EnCana Gathering
Services (U.S.A.) Inc. (Company) and its contractors (Contractor) during construction,
operations, and maintenance of the 16.5 mile proposed Parachute to Logan Wash
Gathering Pipeline Project (project). Preparation of the POD is required by the Bureau of
Land Management (BLM) with the primary objective being to establish procedures for
mitigation of potential environmental impact associated with the project.
1.1 PURPOSE AND NEED FOR THE POD
The purpose of this POD is to provide guidelines for the construction and future
operation and maintenance of the project in compliance with mitigation measures
set forth in the project's Final Environmental Impact Statement (FEIS). The
audience for the POD consists of construction contractors, environmental and
construction inspectors, and operations and maintenance personnel. The POD
contains general information on the project and is not intended as a stand-alone
document. Detailed information concerning specific project -related activities, such
as fire prevention and suppression, soil conservation and erosion control, stream
crossing and wetlands protection, and project designs are provided in the POD
appendices.
1.2 OVERVIEW OF THE POD COMPONENTS
The POD contains an introduction, and a detailed discussion of the proposed
construction activities. In addition, the following environmental compliance plans
are attached to the POD as appendices.
• Appendix A: Environmental Management
• Appendix B: Soil Conservation, Sedimentation, and Erosion Control Plan
• Appendix C: Stream Crossing and Wetland Protection Plan
• Appendix D: Hydrostatic Testing Plan
• Appendix E: Reclamation Plan
• Appendix F: Fire Prevention and Suppression Plan
• Appendix G: Hazardous Materials Management and Spill Prevention and
Countermeasure Plan
• Appendix H: Safety Plan
• Appendix I: Engineering Drawings / Alignment & Profiles
1.3 PROJECT OVERVIEW
The project consists of approximately 16.5 miles of 24 inch diameter buried natural
gas pipeline and related facilities. The pipeline begins at an existing compressor
facility (Roan Cliff) located approximately 2 miles north of Parachute, Colorado
and extends southwesterly to a termination point on BLM property located 4 miles
north of the Town of DeBeque, Colorado.*Construction will occur on two
construction spreads and is scheduled to start on or before June 1, 2004 with a
completion approximately 17 weeks later.
The natural gas pipeline will be constructed of 24" OD; X-65; 0.500 wall; epoxy
fusion bond coated pipe. Road bores will utilize 24" OD; X-65;0.625 wall; coated
pipe incased inside 30" OD; 0.375 wall bare casing. Construction will meet API
1104, ASME B31.8, and DOT specifications. The pipeline will be installed with a
minimum 48 inches of cover over the pipe with the exception of creek and road
crossings in which case a minimum of 60 inches of cover will be required. The
pipeline will be operated with induced current cathodic protection and will be
hydro -tested to meet DOT (Class II) standards to achieve a MAOP of at least 1440
psi. Sizing of the pipeline was engineered so as to accommodate all current and
future natural gas development including potential gas production from the
Orchard Mesa north and south fields.
The planned route and alignment of the pipeline will begin on American Soda
property at the existing EnCana Roan Cliff Compressor Facility 2 miles north of
Parachute, Colorado, and traverse southwesterly across private land into CDOT
Highway 6 right-of-way approximately 1.5 miles west of Parachute. The pipeline
will parallel the existing Williams Production 20 inch pipeline within CDOT right-
of-way to a point approximately 4 miles northeast of DeBeque, Colorado. From
that point, the pipeline will exit CDOT right-of-way and continue in a
northwesterly direction across private and BLM land, terminating at a interconnect
with the TRANSCO Pipeline located in Logan's Wash. Natural gas will be
measured and delivered into the TRANSCO Pipeline at that point.
Traffic impacts to County and State roadways will be minimized where possible.
The construction contractor will be required to limit the number of vehicles /
allowed on the right-of-way and buses will be required for the transportation of
non -specialized personnel to the job site. Anticipated numbers of
required, during the construction phase of the project, are projected to be +1- t!) t qc
individuals on a daily basis. Not included in these numbers are approximately 4 to
6 third party inspectors whose job will be to insure compliance of construction
procedures and private and BLM stipulations.
Following the installation of the pipeline, the ROW will be cleaned up, re-
contoured and re -vegetated with the specified certified seed mixes. Re -growth of
the vegetation will be monitored to insure rehabilitation of the disturbed areas.
1.4 PURPOSE AND NEED
Currently, natural gas production from EnCana wells in the Rifle, Colorado area is
gathered, conditioned, and delivered to transmission pipeline connections in the
Rifle and Parachute areas. EnCana has recently negotiated a "short term" contract
with Williams Production for transportation of 100 mmscfd of gas in their existing
20 inch pipeline from Parachute to the TRANSCO Pipeline. Existing transmission
pipelines, out of the basin, available for the purpose of delivering natural gas to
markets, have limited capacities and experience high pressures due to line packs.
The proposed EnCana 24 inch pipeline would allow current and future gas volumes
to reach additional markets. Current and future natural gas development would be
severely curtailed without expanded pipeline infrastructures.
1.5 REGULATORY PERMIT REQUIREMENTS
The following sections outline the basic regulatory process that the project must
complete prior to the start of construction. Table 1 contains a list of agency
permits and actions. A detailed listing of highway crossing permits and other non -
discretionary permits is not included.
1.5.1 Environmental Compliance Activities
EnCana Gathering Services (U.S.A.) Inc. applied to the U.S. Department of
the Interior, BLM for ROW grants and permits to cross federal lands
managed by the BLM. The BLM in accordance with the National
Environmental Policy Act (NEPA) is preparing an Environmental
Assessment addressing construction and operations impacts and appropriate
mitigation measure requirements.

During construction, operations, and termination of the project, a copy of the complete
BLM ROW Grant, including all stipulations and the approved POD, will be available at
the construction office. Also, the Environmental Inspector will carry a copy of the
complete BLM ROW Grant including all stipulations and the approved POD. The
Company will obtain all required federal, state, and local permits. In addition to
complying with the requirements in these permits, the project will also abide by the valid
existing rights of all permittees, licensees, ROW holders, leases, mining claimants, and any
other holders of valid authorizations on BLM lands traversed by the project.
During construction, should the Contractor identify an area requiring additional workspace
not previously authorized, the Contractor will provide the company with the necessary
information for submittal to the BLM for a Temporary Use Permit or other authorization
as applicable. Contractor will limit ROW clearing and usage to the minimum required
area for construction operations.
2. PROJECT PARTICIPANTS
2.1 PRIMARY PROJECT PARTICIPANTS
Key participants in the project will include personnel from EnCana Gathering Services
(U.S.A.) Inc., the BLM (the lead agency), and the Contractor.
2.1.1 EnCana Gathering Services (U.S.A.) Inc. Project Personnel
EnCana Gathering Services (U.S.A.) Inc. has identified specific positions and
personnel for the project with authority to receive, act upon, and implement
instructions from the BLM.
Overall management of the project will be performed by Wagon Wheel
Consulting (WWC) located in Rifle, Colorado. The WWC Project Manager will
be responsible for all consultants and actions relating to the environmental
management program. WWC's Construction Inspector will be responsible for all
inspection activities except environmental inspection.
2.1.2 Construction Personnel
The pipeline spread will be constructed by a pipeline contractor who will have a
Construction Manager located at the spread's construction yard. The pipeline
Construction Manager will coordinate with the WWC Project Manager.
2.1.3 Agency Personnel
The Grand Junction Field Offices of the BLM is responsible for all activities on
the federal lands. The Grand Junction Field Office Authorized Officer is the
contact person for the Project.
3. PROJECT FACILITIES
The project consists of permanent project facilities as well as temporary project facilities that
will be necessary only during construction of the project. A 75 -foot wide work area will be
required on BLM land during construction, of which 30 feet will be maintained as a permanent
pipeline ROW. On private land and CDOT right of way, a 65 -foot wide work area will be
required during construction, of which 30 feet will be maintained as a permanent pipeline ROW.
Other permanent project facilities include meter stations and block valves. Permanent project
facilities are discussed in greater detail below.
3.1 PERMANENT PROJECT FACILITIES
3.1.1 Facility Sitings, Engineering, and Design
The pipeline route has been selected to avoid as many areas of special concern as
possible. These special areas include areas of critical environmental concern,
cultural resource areas, paleontology resource areas, and areas of high visual
quality. Other specific measures that have been implemented during the routing
of the ROW include the following.
• Where waterbodies meander or have multiple channels, the pipeline has been
realigned, when feasible, to minimize the number of waterbody crossings.
• When engineering and routing conditions permit, streams will be crossed
perpendicular to the channel to minimize length of disturbance
• The project has been routed along established utility corridors when feasible,
to avoid crossing areas of concern.
• The pipeline has been sited so that it is not within 50 feet of a residence in
residential areas.
• Current land uses along the ROW include primarily agricultural lands,
pasture, and industrial lands. The pipeline ROW does not cross recreational
land.
The design of the project's pipeline will be in conformance with the requirements
of Title 49 Code of Federal Regulations (CPR), Part 192, "Regulations for the
Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety
Standards" U.S. Department of Transportation (DOT) regulations.
4. CONSTRUCTION ACTIVITIES
The following section provides a description of each phase of standard construction along the
ROW.
4.1 CONSTRUCTON SCHEDULE
Construction activities will occur over an estimated 17 week period. Construction will
begin with pipeline ROW clearing on or before June 2004 and end with hydrostatic
testing in late October 2004. Assuming a reasonable construction kickoff date, expedient
construction progress, and limited weather-related delays, the reclamation and restoration
of the ROW should be completed by October 2004.
In residential areas, construction activities, except for hydrostatic testing, will only occur
between the hours of 7 A.M. and 5 P.M., six days a week (usually Monday to Saturday).
4.2 PROJECT AREA SURVEYING AND STAKING
4.2.1 Pre -Construction Phase
Information from pre -construction surveys was used to help locate project
facilities. Resources identified include: sensitive plant populations; cultural,
archeological, paleontological resources; and wetlands and streams. Mitigation
for sensitive areas that cannot be avoided is addressed in environmental
compliance plans included in this document (e.g., Reclamation Plan, Stream
Crossing and Wetland Protection Plan, and other general and site-specific
environmental compliance plans).
4.2.1.1 Buried Utility Crossings
Buried utility crossings may require extra workspace in order to store the
additional subsoil material removed to place the pipe below the existing
utility. Required utility line separations are determined on a case-by-case
basis in coordination with the affected utility company prior to
construction.
4.2.1.2 River, Stream, and Wetland Crossings
There will be no additional width or staging areas permitted on federal
surface. No wetlands or perennial streams will be crossed on federal
surface managed by the BLM. No wetlands or perennial streams will be
crossed on federal surface managed by the BLM. This procedure is in the
POD for crossings on non-federal land only.
River, stream, and wetland crossings typically require staging areas on
both sides of the crossing. Staging areas are required for pipe storage and
additional subsoil storage resulting from grading down of banks. Staging
areas are also necessary when additional pipe burial depths require deeper
trenches, and therefore additional subsoil storage requirements.
On perennial stream and wetland crossings on private and state lands,
staging areas will be located at Least 50 feet from the stream bank or
wetland boundary to maintain a buffer zone and avoid water.
The project is not expected to impact the Colorado River. However, if the
pipeline should cross a river, Directional Boring techniques will be
utilized to install the pipeline. The borehole will be drilled at an
approximate depth of 20 feet below the lowest point of the river bed.
4.2.2 Construction Phase
The civil engineering surveys will be performed by WAGON WHEEL CONSULTING,
INC. to identify the centerline of the pipeline and the boundaries of both sides of the
approved working limits before construction activities occur in an area as follows:
• On private lands -Chaining stakes will be set at 200 -foot intervals along the
centerline. In addition to the stakes, flagged or painted lath will be set at 400- foot
intervals (maximum), or as required to maintain line of sight, along the proposed
centerline. The edges of the work limits will be marked at 200 -foot intervals
(maximum), or as required to maintain line of sight, with flagged or painted lath. All
extra workspace will be marked in a similar fashion and all four comers of each extra
workspace will be marked by a flagged or painted lath.
• On federal lands -Chaining stakes will be set at 200 -foot intervals along the
centerline. In addition to the stakes, flagged or painted lath will be set at 400- foot
intervals (maximum), or as required to maintain line of sight, along the proposed
centerline. The edges of the work limits will be marked at 100 -foot intervals
(maximum), or as required to maintain line of sight, with flagged or painted lath
unless greater spacing is granted by the Authorized Officer's field representative.
Extra workspace will be marked in a similar fashion and all four will be marked by a
flagged or painted lath. Extra workspaces on steep slopes (greater than 40 percent)
and at staging areas (stream, wetland, and river crossings) will be staked at 50 -foot
intervals.
Environmental Inspectors will be responsible for verifying that the limits of authorized
construction work areas are staked and approved access roads are signed prior to
construction.
4.3 PIPELINE CONSTRUCTION SEQUENCE
The following sections include general descriptions of the various pipeline construction phases.
Also included in these sections are specific applicable mitigation requirements that will be
implemented by the Contractor. The following operations are typical in a construction spread.
4.3.1 Clearing and Grading
Clearing, grading, and other disturbance of soil and vegetation will be limited to the
minimum area required for safe construction operations within the approved ROW and
extra workspaces. Root systems will be left in place where feasible and where they do
not pose a safety concern for workers or an impediment to equipment or rubber -tired
vehicle access. The herbaceous vegetative crown will be maintained to the extent
possible where blading of the ROW and extra workspaces are not necessary. Once
clearing has been performed to remove any obstacles or debris, grading will follow to
remove the topsoil and surface rock, and stockpile it within the edge of the ROW for
redistribution following Construction.
All brush and other materials that are cleared will be windrowed within the ROW or in
temporary use areas. Following construction, these materials will be dispersed over the
ROW to impede future access along the ROW and to provide wildlife habitat unless ROW
stipulations dictate otherwise. Trees will be voided of dirt and strategically placed on
ROW to impede future access.
4.3.1.1 Clearing and Grading Requirements
The Environmental Inspector will ensure that the Contractor implements the
following mitigation measures during clearing and grading operations:
• Clearing will be performed to preserve roots to the extent practicable,
stockpile or dispose of vegetation wastes to maintain stability of the site, and
provide erosion control. Trees will be cut with chain saws and/or mechanical
shears/saws. Brush will generally be cut with a hydro -axe or similar
equipment. Steep slopes will be graded properly to minimize erosion.
Specific erosion control measures to be implemented are detailed in the Soil
Conservation, Sedimentation, and Erosion Control Plan.
• Vegetation cut during clearing operations will be stockpiled on the ROW
(timber, etc.). In some cases trees, stumps, or slash may be scattered back
over the ROW after seeding to aid in erosion control, and to block access
along the ROW.
• In order to reduce the amount of soil exposed to erosion, the Contractor will
1) minimize cuts and fills, and 2) will not use cut and fill construction
techniques unless slopes exceed three percent where feasible. Topsoiling
requirements are included in the Soil Conservation, Sedimentation, and
Erosion Control Plan.
• Cleared vegetation will be disposed of as directed by the BLM's field
representative on federal lands. Where feasible and when agreed to by the
BLM field representative, the Contractor may use slash for on-site
reclamation. Placement of slash will not interfere with other reclamation
activities including seeding and planting.
• On state and private lands, cleared vegetation will be disposed of as requested
by the property owner and approved by the Environmental Inspector.
• Pinyon or Juniper tree removal on BLM land may require a permit. The
environmental inspector will coordinate with BLM to determine necessity of
said permit.
4.3.2 Trenching
Construction methods used to excavate a trench will vary depending on soils, terrain, and related
factors. Where possible, rotary -trenching machines will be used. In situations such as steep
slopes, unstable soils, high water table, or deep or wide trench requirements, conventional track
type backhoes will generally be used.
Measures will be taken to ensure that access is provided for property owners or tenants to move
vehicles, equipment, and livestock across the ditch where necessary. Adequate precautions will
also be taken to ensure that livestock are not prevented from reaching water sources because of
the open ditch. Measures to be taken include contacting livestock operators, providing adequate
crossing facilities, or other measures as needed.
Contractor will also ensure that every half -mile that there is either a natural egress ramp in the
trench (stream or road crossing) or a soft or hard plug ramp for wildlife and cattle to escape from
the ditch.
A typical ditch will be excavated approximately 36 -inches wide at the bottom and the sides will
be sloped to Occupational Safety and Health Administration (OSHA) specifications. The depth
of the ditch will be approximately 66- to 72- inches deep; however, it will vary with the
conditions encountered. The cover from top of pipe to ground level as graded to finish ROW
will be in conformance with DOT regulations. Occasionally, the ditch will be excavated to
depths greater than the minimum values specified. Greater depths of cover will be required at
unpaved road crossings, foreign pipeline crossings, streams, or other obstructions. As a
minimum, the ditch will be excavated to a depth to allow a clearance of 18 inches between the
EnCana Gathering Services (U.S.A.) Inc. pipeline and other pipelines or underground facilities.
Machine excavation will not be performed closer than 5 feet from any existing pipeline
encountered in the ROW unless authorized by the pipeline owners/operators. Existing pipeline
locations will be marked in the field and 48-hour prior notification given to the operator of the
underground utility.
Pipeline crossings of unsurfaced, lightly traveled, or rural roads will be made with a mechanical
ditching machine or a backhoe. Installation at these locations, including cleanup and restoration
of road surfaces, will usually be completed within one day. In such cases, provisions will be
made to detour or control passage of traffic during construction.
Where rock is encountered, tractor -mounted mechanical rippers or rock trenching equipment
may be used to facilitate excavation.
4.3.2.1 Trenching Requirements
EnCana Gathering Services (U.S.A.) Inc. Environmental Inspector will ensure that the
Contractor implements the following mitigation measures during trenching operations:
• Trenching will be performed to minimize disturbance to soils generally by
using a backhoe or trenching machine. Topsoiling requirements are included
in the Soil Conservation, Sedimentation, and Erosion Control Plan.
• No trench within 250 feet of a residence will be left open for more than three
days.
4.3.3 Boring
Boring techniques will generally be used under paved highways to avoid disrupting traffic in
accordance with the governing agency requirements and permitting agreements. F or both cased
and uncased crossings, the auger boring technique and the directional boring technique described
below will be implemented.
The auger boring technique involves excavating a bore pit on one side of the crossing and a
receiving pit on the other side and utilizes an auger and power unit mounted on rails or a side
boom suspended boring machine attached to a deadman. The power unit drives the auger inside
a heavy wall pipe casing segment until the power unit reaches the leading edge of the bore pit.
The power unit is disconnected from the auger, backed up, and a segment of the carrier pipe is
welded to the casing segment already driven. Additional auger and carrier pipe segments are
added successively until the bore reaches the other side of the crossing in the receiving pit. Soil
excavated by the auger is removed from the pit by a backhoe. Once through, the power unit
backs out the auger one segment at a time, leaving the gas pipeline in place under the crossing.
In the receiving pit, the casing segment is removed for use at the next crossing.
The directional boring technique involves using a hydraulic powered machine to drill a near
horizontal bore hole for great distances. This method utilizes conventional drill bits attached to
drill pipe in order to drill a bore hole for the required length. Drilling muds (Bentonite) are
pumped through the drill bit and in turn carry cuttings back along the drill pipe and are then
recovered into tanks located at the power unit. All drilling muds are then filtered and recycled.
Once the bore hole has been drilled to the desired length, the drill bit is removed and a
backreamer is attached to the drillpipe. The backreamer is pulled back through the bore hole to
clean and size the hole. Multiple sizes of backreamers are pulled through the bore hole until the
desired hole size is achieved. Once the final backreamer has been pushed through, the pre -
welded and tested carrier pipe is then attached to the backreamer and pulled through the bore
hole. The carrier pipe is then welded to the main pipeline at each end.
4.3.4 Pipe Installation
Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment,
welding the pipe segments together, x-ray/inspection, coating the joint areas to prevent corrosion,
and then lowering -in and padding as described in greater detail below.
4.3.4.1 Stringing
Line pipe will be shipped directly from the manufacturer by rail to pipe yards and then
hauled by truck to the pipeline ROW. Each individual joint of pipe will be unloaded by
cranes or tractors equipped with side booms and slings, and strung parallel to the ditch.
Sufficient pipe for road or stream crossings will be stockpiled at staging areas near the
crossings.
Stringing operations will be coordinated with trenching and installation activities to
properly manage the construction time at a particular tract of land. Gaps will be left at
access points across the ditch to allow crossing of the ROW.
4.3.4.2 Bending
After the joints of pipe are strung along the ditch but before the joints are welded
together, individual joints of the 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.
4.3.4.3 Welding
After the pipe joints are bent, the pipe 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,"
latest edition.
4.3.4.4 X -Ray Inspection
All welds will be visually inspected by a qualified inspector and by non- destructive
radiographic methods. At a minimum, radiographic inspection will be conducted in
accordance with DOT requirements. A specialized contractor, certified to perform
radiographic inspection, will be employed to perform this work. Any defects will be
repaired or cut out as required under the specified regulations and standards.
4.3.4.5 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 a synergy coating. 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 ("holidays") will be repaired.
4.3.4.6 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 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 subsoils to provide rock -
free pipeline padding and bedding. In rocky areas, padding material or a rock shield will be
used to protect the pipe.
4.3.5 Backfilling
Backfilling will begin after a section of the pipe has been successfully placed in the ditch and fmal
inspection has been completed. Backfill will be conducted using a bulldozer, rotary auger
backfiller, padding machine or other suitable equipment. Backfilling the trench will generally use
the subsoil previously excavated from the trench, except in rocky areas where imported select fill
material maybe needed. 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 95% maximum density as determined by AASHTO T -99. Backfill of trenches will
not be performed where the soil is frozen to the extent that large consolidated masses are formed
that will not "break down". Contractor will then re -spread the topsoil to return the surface to its
original grade. In agricultural areas, the Environmental Inspector will test the backfill to ensure
that it has been replaced at the same compaction density as the adjacent undisturbed soil. Any
excavated materials or materials unfit for backfill will be utilized or properly disposed of in
confomiance with applicable laws or regulations.
4.3.5.1 Backfilling Requirements
EnCana Gathering Services (U.S.A.) Inc. Construction and Environmental Inspector will
ensure that the Contractor implements the following mitigation measures during backfilling
operations:
• Trench breakers, to prevent groundwater migration, will be constructed as defined in
the project's Soil Conservation, Sedimentation, and Erosion Control Plan. The project's
Construction Inspectors will approve locations in the field sites.
4.3.5.2 Backfilling Requirement Variance Request
The Contractor will place a mound over the trench approximately 0.5 feet to account for
subsidence. On federal lands, a variance is required to eliminate the mound. On private
lands, written authorization from the property owner is required to eliminate the mound.
4.3.6 Hydrostatic Testing
The entire pipeline will be tested in compliance with DOT regulations (49 CFR Part 192). Prior to
filling the pipeline for a hydrostatic test, each section of the pipeline will be cleaned by passing
reinforced poly pigs through the interior of the line. Incremental segments of the pipeline will then
be filled with water, pressurized, and held for the duration of the test. The length of each segment
tested will depend on topography.
Typically, the hydrostatic tests of individual segments will be conducted in sequence and the test
water will be transferred from one segment to another. Test water will be obtained from only
approved sources. When water is obtained from streams, rivers, or reservoirs, the water intake will
be screened to prevent capture of fish or debris. Sources for test water are included in the
Hydrostatic Testing Plan.
Water for hydrostatic testing will be appropriated from various sources utilizing portable pumps
driven by diesel engines. To prevent environmental damage from potential diesel fuel spills during
the operation of the engine(s), additional measures will be implemented when the pumps are
located within 100 feet of a stream or river as described in the Hydrostatic Testing Plan.
In Colorado, hydrostatic test water may be discharged directly into surface water provided the
water is tested for certain components (in accordance with permit requirements) and discharge
velocities are dissipated by implementing measures to diffuse the energy of the discharged water as
described in the Hydrostatic Testing Plan Section 3.2.
4.3.6.1 Hydrostatic Testing Requirements
EnCana Gathering Services (U.S.A.) Inc. Environmental and Construction Inspectors will
ensure that the Contractor implements the following mitigation measures during hydrostatic
testing operations:
• Test water will be procured from an existing EnCana Gathering Services (U.S.A.) Inc.
facility.
• EnCana Gathering Services (U.S.A.) Inc. will sample test water in accordance with
applicable discharge permits.
• Dewatering will be performed in accordance with measures defined in the Hydrostatic
Test Plan and project permits.
4.3:.7 Cleanup and Restoration
Cleanup and restoration of the surface along the ROW and any temporary workspaces will be
performed by removing any construction debris and by performing final grading to the finished
contour. Steps will be taken to minimize erosion, restore the natural ground contour, and account
for trench settling as described in the Soil Conservation, Sedimentation, and Erosion Control Plan.
Restoration seeding and planting will also be performed in accordance with landowner or BLM
requirements and as described in the project's Reclamation Plan.
4.3.7.1 Cleanup and Restoration Requirements
EnCana Gathering Services (U.S.A.) Inc. Environmental Inspector will ensure that the
Contractor implements the following mitigation measures during cleanup and restoration
activities:
• The Contractor will ensure that rocks larger than four inches in any shape or dimension
are removed from all segregated topsoil in agricultural and residential areas.
• Rocks on the ROW will be removed by the Contractor to approximate pre- construction
conditions. Rocks left on the ROW will be scattered in a random manner. Rocks
removed from the ROW will be disposed at a project approved disposal site.
• All existing improvements, such as fences, gates, irrigation ditches, and cattle guards,
will be maintained and repaired by the Contractor to at least preconstruction condition
and to the satisfaction of the landowner or BLM field representative to minimize
disturbance to the public.
• No topsoil will be used for pipeline padding.
• No tailings from the proposed boring areas will be spread or stored on federal surface.
4.3.8 Residential Areas
Special construction activities will be enacted when crossing through residential arleas. The
following construction practices will be implemented:
• If the trench is left open overnight within 250 feet of a residence, it will be fenced to mitigate
safety concerns.
• Owners of private roads along the route will be notified at least 24 hours in advance of planned
road crossings
• Private road crossings will be completed within three hours and roads will be restored to pre -
construction condition or better.
• Access to and from residences will be maintained at all times unless expressed authorization is
obtained from the landowner.
• Construction activities, except for hydrostatic testing, will only occur between the hours of 7
AM and 5 PM, six days a week (usually Monday to Saturday) in residential areas.
• No trench within 250 feet of a residence will be left open for more than three days. If the
trench is left open overnight within 100 feet of a residence. Contractor will fence the area to
mitigate safety concerns.
• .In residential areas, topsoil replacement (i.e., importation of topsoil) is an acceptable
alternative to topsoil segregation.
4.3.9 Livestock Barrier and Other Livestock Issues:
Prior to construction, WWC and EnCana Gathering Services (U.S.A) Inc. will meet with affected
ranchers to discuss their concerns and to explain pipeline construction activities that may impact
livestock. Fences crossing the ROW will be braced, cut, and temporarily fitted with gates to permit
passage. Prior to cutting the fences, the Company will notify the ranchers in order to give them the
opportunity to be present when the fence is cut. During construction, the opening will be
controlled as necessary to prevent the escape of livestock. Existing fences will be replaced and
braces left in place upon completion of construction activities. During construction, Contractor
will take care not to obstruct or damage gates or cattleguards. Those damaged or made inoperable
will be repaired to the agency and/or landowner satisfaction.
WWC will ensure that livestock barriers are in place where the pipeline construction has created
possible problems. The preferred method is to create rock faces or other natural barriers where
available. Where this will not or may not work in the opinion of the Authorized Officer, a 4 -wire
1 )wn fence will be constructed as specified in the Reclamation Plan.
4.3.9.1 Livestock Related Requirements
WWC Environmental and Construction Inspectors will ensure that the Contractor
implements the following mitigation measures relating to fencing:
• The Contractor will repair all damaged livestock facilities (fences, water sources) to the
landowner's satisfaction. These facilities will be left in as good as or better condition
than the pre -construction condition. The Contractor will install temporary fences when
necessary to prevent livestock movement across fences temporarily removed for
construction.

1. INTRODUCTION
This Soil Conservation, Sedimentation, and Erosion Control Plan (plan) describes measures to be
taken by the EnCana Gathering Services (U.S.A.) Inc. (Company) and its contractors
(Contractor) to protect topsoil; to control and minimize soil erosion and resulting sedimentation,
to encourage revegetation, restoration, and stabilization of disturbed soils on the project; and to
protect the pipeline from erosion during and after pipeline construction and restoration.
Measures identified in this plan apply to work within the defined project right-of-way (ROW),
access roads, all work and storage areas, and other areas used during construction of the project.
This plan was developed as the implementing document for relevant mitigation measures for the
EnCana Gathering Services (U.S.A.) Inc. Project. This plan was also prepared as part of the
Storm Water Pollution Prevention Plan as required under Title 40, Code of Federal Regulations
(CFR), Parts 122-124. (National Pollution Discharge Elimination System permit for Storm water
Discharges. )
1.1 OBJECTIVES
Short-term objectives of this plan are to conserve and protect topsoil, to control erosion
and sedimentation, to protect water quality and aquatic resources, to encourage
exclamation/revegetation success, and to minimize impacts to adjacent land uses and
ecological resources. Properly executed construction practices, and ongoing evaluation
by environmental and construction inspectors, and Contractor personnel, will ensure the
continued functioning of erosion and sediment control measures.
Long-term objectives include control of erosion and sedimentation, as well as restoration
of topography, water resources, soils, and vegetation to a condition similar to that, which
existed prior to construction. Monitoring activities during the construction, operations,
and maintenance phases will evaluate the success of the erosion control and revegetation
efforts. In addition, as described in the Plan of Development (Section 5.2) and the
Reclamation Plan (Section 6.3).
1.2 RESPONSIBILITIES
1.2.1 Company
The Company will be responsible for ensuring that the Contractor meets the standards
defined in this plan to retain topsoil where required and to install and maintain sediment
and erosion control measures. Additionally, the Company will be responsible for
meeting the long-term restoration and soil stabilization standards after the project is
completed.
1.2.2 Contractor
The Contractor will be responsible for conducting grading and topsoil separation
activities, installing and maintaining temporary and permanent erosion control measures,
and restoring original contours on the ROW according to the standards detailed in this
plan and related plans listed in Section 1.4. The Contractor is responsible for monitoring
the effectiveness of the installed devices and correcting any conditions that do not meet
the specifications of this plan. WWC's Environmental and Construction Inspectors will
ensure that the Contractor properly installs and maintains erosion control measures.
Installation of most erosion control devices will be performed during the construction
phase. Erosion control measures implemented during construction may include
waterbars, trench breakers, silt fence sediment barriers, straw bale sediment barriers,
interim mulching, tackifier application, and culvert installation. Work related to
permanent erosion control measures implemented during restoration may include seedbed
preparation, seeding, planting, waterbars, trench breakers, permanent mulching, erosion
control matting, silt fence sediment barriers, and straw bale sediment barriers.
1.3 COORDINATION
This plan has been prepared through consultation and coordination with the Company,
regulatory agencies, and landowners. The Company will be responsible for distributing
copies of this plan to all appropriate agencies, construction personnel, BLM and, on
request, to private landowners. It will be the responsibility of the Company to maintain
coordination and communication with the BLM.
1.4 RELATED PLANS AND DRAWINGS
This plan is related to other plans contained in the Plan of Development (POD). The
Contractor will be responsible for complying with the requirements of all these plans,
including:
• Construction Alignment Sheets
• Stream Crossing and Wetland Protection Plan
• Reclamation Plan
• Hazardous Material Management and Spill Prevention and Countermeasure Plan
2. SOIL CONSERVATION MEASURES
2.1 GENERAL CONSIDERATIONS
2.1.1 Flagging
As described in Section 4.2.2, "Construction Phase", of the POD, the Company
will flag and/or stake the boundaries of the ROW, extra workspace, ancillary
areas and any sensitive areas prior to construction. The Contractor will install
additional flagging or fencing as determined by WWC's Environmental
Inspectors and the BLM field representatives to protect sensitive resources located
near the ROW, and will ensure that the construction crews clearly understand and
respect the flagging, fencing, and/or staking. Flagging spacing intervals, also
described in Section 4.2.2 of the POD, will be shortened if necessary to ensure
that flagging is visible, especially in areas with rapidly changing topography or
dense vegetation. Conversely the BLM's field representative may issue a variance
allowing the Company to increase flagging spacing requirements, especially in
areas where there are only low shrubs or grasses, and the stakes are easily visible.
2.1.2 Environmental Training
All workers taking part on the project will attend an environmental training
program that will include discussion of general erosion and sediment control
requirements, proper clearing and grading methods, and the importance of
protecting sensitive resources on the project. Crews specializing in erosion
control tasks will be given additional training on installation and maintenance
methods.
2.1.3 Clearing
Clearing requirements are defined in Section 4.3.1, "Clearing and Grading", of the
POD. Trees will be cut with chain saws and/or mechanical shears/saws. Brush
will generally be cut with a hydro -axe or similar equipment. Vegetation cut
during clearing operations will be removed from the ROW (merchantable timber,
posts, etc.) or will be chipped or shredded within the ROW. In some cases trees,
stumps, or slash may be scattered back over the ROW after seeding to aid in
erosion control, and to block access along the ROW.
The Company and land management agency representatives will coordinate in the
field to designate areas where unmerchantable timber can be made available to the
public for firewood. This wood will be cut in 6 to 8 ft. lengths, and stockpiled on
the ROW or within approved temporary extra workspaces at points where the
ROW crosses access roads (in a manner such that the stockpiled wood will not
hinder reclamation efforts). EnCana Gathering Services (U.S.A) Inc. may require
approval of additional extra workspace in areas where the land management
agency or the landowner requests stacking of firewood especially in areas where
construction workspace is limited. Disposition of vegetation (timber, firewood,
brush, slash) will meet the requirements of the landowner or BLM. No material
will be placed outside the approved work limits on federal land unless a variance
is granted by the BLM. Approved work limits are defined as the legal ROW plus
approved extra workspace.
Clearing, grading and other disturbance of soil and vegetation will be limited to
the minimum area required for safe construction operations within the approved
ROW. Root systems will be left in place where feasible and where they do not
pose a safety concern for workers or an impediment to equipment or rubber -tired
vehicle access. The herbaceous vegetative crown will be maintained to the extent
possible where blading of the ROW is not necessary.
In areas of special resource concern as determined in the field by the BLM and
Environmental Inspectors during pre -construction reviews, clearing of the ROW
may be limited to less than 75 feet to protect significant vegetation.
2.2 TOPSOIL CONSERVATION
Topsoil will be salvaged and protected along the pipeline route to facilitate revegetation
of the ROW after construction is complete. Areas where the majority of surface material
is rock, will not be topsoiled.
All topsoil will be removed up to a depth of 12 inches in accordance with the topsoil
method specified in each reclamation with, or as directed by the land manager or
landowner.
2.2.1 Trench Line Only Topsoil Salvage
As detailed in the Stream Crossing and Wetland Protection Plan, topsoil will be
salvaged from over the trench line only in wetlands and where subsoil grading is
not necessary. This topsoil will be stored separately from trench subsoil and will
be replaced over the trench line once backfilling is complete.
2.2.2 Trench and Spoil Side Topsoil Salvage
Topsoil will be stripped from over the trench line and the adjacent subsoil storage
areas. This method will be specified when subsoil grading is not necessary.
2.2.3 Full -Width Topsoil Salvage
This topsoil salvage method will be used if ROW grading is needed to create a
level work area (e.g., for a side hill cut, etc.), or if requested by the landowner or
BLM. In general, on the BLM, topsoil (or the top 6 inches) will be stripped and
separated from trench spoil, for the width of the ROW, or 75 feet. Topsoil will
first be stripped from the entire area to be graded and then stored separately from
the subsoil. NO TOPSOIL WILL BE USED FOR PIPELINE PADDING.
2.2.4 General Requirements
The following guidelines apply to salvaging topsoil, unless otherwise approved by
the Environmental and Construction Inspector, and BLM field representative.
• All available topsoil will be salvaged, up to a maximum of 12 inches, unless
otherwise directed by the landowner or BLM.
• Salvaged topsoil will be kept separate from subsoil and protected throughout
subsequent construction activities to prevent mixing that could potentially
inhibit reclamation of the ROW.
• To protect topsoil and subsoil, dry drainages or washes that cross the ROW
will not be blocked with spoil piles. This will be accomplished by placing
spoil on the banks of the drainage or by leaving adequate gaps in the spoil
piles of wider dry drainages so that the ROW can drain. Where dictated by
slope and the proximity of a dry drainage running parallel (or nearly so) to the
ROW, either within or immediately adjacent to the ROW, and if deemed
necessary by the Environmental Inspector and BLM representative, sediment
barriers may be installed to prevent spoil and topsoil from entering the
drainage.
2.3 RESTORATION
After the fmal installation of the pipeline, all disturbed portions of the construction areas
(including the ROW, travel routes, and staging areas) will be returned to pre -construction
grades and contours. Topsoil will then be replaced over the ROW from the area in which
it was stripped.
Revegetation will be the primary method to stabilize soils and ensure permanent erosion
control over the long term. Revegetation techniques, including decompaction and
seeding are presented in detail in the Reclamation Plan. Every effort will be made to
complete fmal cleanup and installation of permanent erosion control measures within 30
days after fmal backfilling is completed.
Permanent waterbars, berms and/or sediment barriers (e.g., straw bales and/or silt fences)
will be installed across the ROW up slope of streams, rivers, and wetlands. Mulch or
fiber matting will be applied to disturbed surfaces within 100 feet of the crossing unless
otherwise directed by the BLM. Additional details relevant to waterbody and wetland
restoration are discussed in the Stream Crossing and Wetland Protection Plan.
Information on revegetation procedures at waterbody crossings is presented in the
Reclamation Plan.
3. EROSION AND SEDIMENT CONTROL
3.1 GENERAL CONSIDERATIONS
The following general environmental protection measures will be implemented to
minimize environmental impacts during construction and operation of the project.
• All personnel, vehicles, and equipment will stay in the designated construction area.
Access roads outside of the construction area will be designated by the Company. All
staking, flagging and exclusion fencing will be respected.
• Temporary erosion/sediment control devices will be installed immediately after initial
soil disturbance and will be maintained throughout construction and restoration, as
necessary, until replaced by permanent erosion control measures. If possible, cleanup
will be completed and permanent erosion control measures will be installed within 30
days after the trench is backfilled to aid in site stabilization. If circumstances prevent
achieving cleanup within 30 days on federal lands, the Company will apply for a
variance from the managing agency.
• An Environmental Inspector will be employed in the field during construction to
verify compliance with the environmental protection measures.
• Disturbance during construction will be limited to the minimum necessary to safely
and efficiently complete construction activities.
• Construction, clean-up, and reclamation will be completed as quickly as possible to
keep the time period between grading, trench excavation, backfilling, and final
restoration/reclamation to a minimum. If weather conditions preclude final
reclamation of a site (excluding woody plantings, if applicable) immediately
following construction, the Company will meet with agency representatives to discuss
viable reclamation alternatives.
• A stockpile of erosion control materials including straw bales, silt fences, erosion
control matting, and geotextile fabric will be stored at each of the staging areas during
the entire period that construction disturbances are taking place. Materials will be
stored for planned use during construction, and additional quantities will be
maintained for maintenance and emergency use.
3.2 EROSION CONTROL METHODS
Temporary control measures are designed to effectively reduce erosion and sedimentation
to sensitive resources during construction. These temporary erosion control measures
will be installed concurrently with construction earthwork and will be maintained
throughout the course of construction. When necessary, these measures may be left in
place along with permanent measures during the post construction period until effective
revegetation has been reestablished. Sediment barriers and waterbars (as described
below) will be the primary measures for temporary erosion control used on the project.
Interim erosion control measures are designed to temporarily stabilize portions of the
disturbed construction area near sensitive resources if construction is delayed for
significant periods following disturbance. If final cleanup of pipeline construction areas
and installation of permanent erosion control measures is not completed in an area within
30 days following backfilling, mulch will be applied on slopes within 100 feet of water
bodies (as defined in Section 1.3 of the stream Crossing and Wetland Protection Plan)
and wetlands. Mulch or erosion control matting will also be applied on slopes greater
than 30 percent and as determined by the Environmental and Construction Inspector, and
BLM field representative if construction or restoration is interrupted for extended
periods. Additional discussion of interim mulching is included in the Upland Erosion
Control, Revegetation, and Maintenance Plan and Section 3.2.5.1 of this plan.
• Permanent erosion control measures are designed to minimize erosion and
sedimentation after construction until revegetation efforts have effectively stabilized
the construction area. Installation of permanent erosion control measures should be
performed within 30 days following backfilling of the trench.
In general, temporary erosion control measures will be removed after permanent erosion
control measures have been installed.
The following sections review materials, installation requirements, and performance
criteria for temporary, interim, and permanent erosion and sediment control measures.
3.2.1 Sediment Barriers
Straw bale sediment barriers and silt fence sediment barriers are temporary
sediment barriers designed to slow down water flow and to intercept suspended
sediment conveyed by sheet flow, while allowing runoff to continue down
gradient. These installations are used to prevent sediment delivery off of the
construction area as well as to divert water off the construction area. Temporary
sediment barriers will be installed at the following locations immediately after
initial ground disturbance:
o across the ROW at the base of slopes where the ROW crosses roadways,
waterbodies, springs, wetlands, impoundments, and other sensitive resources;
o along the edge of the ROW adjacent to and up slope of roadways waterbodies,
springs, wetlands, impoundments, or other sensitive resources; and
o around topsoil or subsoil piles where necessary (e.g., adjacent to waterbodies
or wetlands).
The requirement to install a sediment barrier is dependent on the slope angle
(when a hillside slopes in multiple directions, the slopes can off -set each other and
reduce the need for sediment barriers), slope length, and soil type (texture and
course fragments content). While typically used only during construction, silt
fences and straw bale sediment barriers may be left in place following seeding,
possibly for a complete growing season.
3.2.1.1 General Requirements
Straw bale or silt fence sediment barriers placed at the toe of a slope will be at
least 6 feet from the toe of the slope, where possible, in order to increase ponding
volume. The ends of the sediment barrier will be turned upslope to capture
sediment.
Sediment barriers will be placed so as not to hinder construction activities and
outside of (above the high water mark) active stream channels. If silt fences or
straw bale sediment barriers are placed across the construction area (adjacent to
waterbodies, wetlands, or roads) where construction traffic is allowed to cross,
provisions will be made for traffic flow. An approximately I5 -foot -wide gap will
be provided along the silt fence or straw bale row, with the ends of the sediment
barrier turned slightly upslope. A drivable earth berm, if approved by the BLM
field representative will be installed and maintained across the gap immediately
upslope of the sediment barrier (ends of the sediment barrier will tie into the
drivable earth berm). Alternately, straw bales will be installed across the gap with
24 inches of overlap with the adjacent sediment barrier at the end of each day.
If sediment loading is noted during regular inspections of temporary sediment
barriers to be at or greater than 40 percent of barrier capacity, sediment behind the
barrier will be spread on the disturbed ROW uphill of the sediment barrier. Loose
stakes, loosely abutted bales, damaged bales, or damaged or undermined sections
of silt fence will be repaired or replaced as necessary.
3.2.1.2 Straw Bales
Straw bale sediment barriers consist of a row of tightly abutted straw bales placed
perpendicular to the runoff direction with the ends turned upslope. The barriers
are typically one bale high, placed on the fiber -cut edge in a 4 -inch trench (tie not
in contact with the ground), and anchored securely with two wooden stakes driven
through each bale. A small amount of soil is then piled across the upslope side of
the straw bale barrier.
When straw bales are used as a temporary substitute for waterbars, the same
spacing noted for waterbars will be used (see Section 3.2.2).
3.2.1.3 Silt Fences
Commercial filter fabrics, with sufficient strength to prevent failure will be
provided by the Contractor. The height of a silt fence will not exceed 36 inches
and the fabric will be cut from a continuous roll of fabric with splices only at
support posts, with a minimum 6 -inch overlap and both ends of fabric securely
attached to the post. Support posts will be a maximum of 10 feet apart.
The bottom edge of silt fences will be installed in a trench excavated
approximately 4 inches wide by 6 inches deep and refilled with compacted soil,
unless on-site constraints dictate otherwise (e.g., rock). Silt fences will be
attached to supporting posts by staples or wire.
If additional support is needed to contain we spoil, or to provide added protection
near a sensitive resource (as determined by the Environmental Inspector and BLM
representative), either wire mesh or straw bales may be placed immediately
behind the silt fence on the down -gradient side. If wire mesh is used, the wire will
be attached to the support posts, prior to installation of the fabric, with heavy duty
wire staples at least 1 inch long, wire ties, or hog rings. The wire will be keyed
into the trench at least 2 inches, and extended up the posts to the top of the filter
fabric.
3.2.2 Waterbars
Waterbars are utilized in various forms (e.g., driveable berms across travelways,
waterbars on slopes) during project construction and after fmal grade restoration.
Waterbars are intended to intercept water traveling down a disturbed slope and divert
water off disturbed soil into stable, well -vegetated, or adjacent rocky areas.
Temporary waterbars will be installed concurrently with initial grading operations and
will be maintained throughout construction. Permanent waterbars will be installed after
the ROW grade is restored.
Waterbars will also be installed near the base of slopes adjacent to wetlands and
watercourses except at those specific sites where, in the judgment of the Environmental
Inspector and BLM representative, waterbars are not necessary to prevent discharge of
sediment into a wetland or watercourse. On slopes, the spacing for temporary and
permanent waterbars will be as follows:
Slope (%) Spacing (feet)
5-15 300
>15-30 200
>30 100
Alternative spacing may be requested by the landowner or BLM for isolated, site-
specific areas and conditions (i.e., in areas of highly erodible soils). Waterbar spacing is
based on a site-specific evaluation of the ROW and standard construction protective
measures. This spacing takes into account the soils, timing of construction, and area of
disturbance anticipated for construction of the project. Waterbars will be sited so that
they do not outlet into sensitive resource areas (cultural sites, rare plant sites, etc.). On
federal land, if waterbar outlet into a sensitive resource area is unavoidable, a variance to
this requirement must be obtained. On private and state lands, it a waterbar outlet into a
sensitive resource area is unavoidable, and Environmental Inspector will ensure that
measures are implemented to minimize impacts.
If the situation warrants an increase to the waterbar spacing intervals, variances will be
coordinated by the Environmental Inspector with the BLM of landowner, as appropriate.
Criteria to be considered for variances will include:
• slope angle (slopes with effective side -slopes may not require waterbars)
• slope length (broken terrain may reduce effective slope length)
• soil type (texture and coarse fragment content)
• visual sensitivity
• landowner requests
Except for site-specific situations as determined by the Environmental and Construction
Inspector, BLM representative (e.g., extremely long slopes with highly erodible soils),
temporary waterbars will not be constructed on slopes with less than five -percent
gradient. Waterbars are not typically installed in residential or active agricultural areas.
Waterbars will be constructed of existing suitable material (compacted soil), a series of
tightly abutted straw bales, excelsior logs, or burlap bags filled with native soil. The
installation angle will be approximately 2 to 5 percent downslope (as measured by a
hand-held clinometer or level) and will extend beyond the edge of the disturbed
construction area. Where possible, waterbars will discharge into stable, non-erosive
(vegetated or rocky) receiving areas.
In isolated instances where waterbars discharge into unstable or highly erosive areas
without rock or vegetation, as approved by the Environmental and Construction
Inspector, and BLM representative, flow energy dissipaters or "J- hook" shaped sediment
barriers will be positioned at the waterbar outlet. However, decreasing waterbar spacing
or adjusting the spacing to locate outlets onto a stable site is preferable to using outlet
energy dissipaters. Additionally, in highly erodible soils, waterbar spacing may be
decreased, as approved by the Environmental or Construction Inspector, and as requested
by the BLM. When allowed by existing topographic conditions, and as requested by the
Environmental Inspector, the flow energy dissipaters will be offset (staggered) on slopes
greater than 20 percent.
The Contractor will regularly inspect and repair waterbars during construction to
maintain their effectiveness. Waterbars worn down by heavy construction traffic, or
filled with sediments will be repaired as needed, and the sediments will be spread on the
disturbed ROW uphill of the waterbar.
3.2.3 Trench Breakers
Trench breakers will be installed in the trench to restrict or slow ground water flow along
the trench line. Trench breakers will be installed in the trench prior to backfilling on
slopes that drain into waterbodies (natural or artificial stream, river, or drainage with
perceptible flow at the time of crossing, and ponds, or lakes), wetlands, and improved
roads. Trench breakers should also be constructed immediately downslope of any
location where groundwater could enter and migrate alonjg the trench at any time or year.
• Trench breakers will be constructed to the specifications contained in the FERC
Upland Erosion Control, Revegetation and Maintenance Plan.
• At the base of slopes adjacent to road crossing until disturbed vegetation has been
reestablished.
• Install temporary sediment barriers at appropriate locations to prevent siltation into
waterbodies or wetlands crossed by or near the construction work area.
Trench breakers can be construction from sandbags or polyurethane foam. If the sandbag
method is selected, topsoil will not be used as a fill material.
3.2.4 Trench Dewatering
The Contractor will be responsible for proper dewatering of the trench, where necessary.
Dewatering discharge will be directed onto a stable surface and will utilize a section of
geotextile fabric or plywood to prevent scouring during overland discharges (where no
sensitive resources are located nearby), or a sediment bag and/or dewatering structure to
minimize sediments when dewatering operations take place near waterbodies or wetlands.
A number of strategies will be implemented to prevent heavily sediment -laden water
from reaching sensitive resources. These strategies include:
• Dewatering discharges will be located as far as practicable from and wetlands.
• Duration of dewatering discharges will be minimized by scheduling dewatering
operation immediately prior to lowering in, tie-ins, or backfilling.
• Disturbance of the trench (i.e., additional digging) will be minimized to the extent
practicable until the majority of the water is pumped out.
Dewatering structures and/or sediment bags will be used to remove heavy sediments from
discharges when dewatering near (within approximately 200 feet of) waterbodies,
wetlands, or other sensitive resources. -Typical Straw Bale Dewatering Structure.
Contractor will comply with applicable permits for hydrostatic test dewatering.
Specific dewatering requirements related to hydrostatic test dewatering are discussed in
the Hydrostatic Testing Plan.

FOR LEVEL AREAS WITH SPARSE VEGETATION
3.2.5 Mulching
Mulching is the application of straw or wood fiber to disturbed soils to minimize the effects of wind
or rain on exposed soils. During rainy condition, mulch reduces the impact of rainfall and slows the
flow of water down the slope. Mulch (as opposed Ito erosion control mats described in Section 3.2.6)
would typically be used across large sections of the ROW to reduce wind erosion and raindrop
impact. On the BLM portion of the project, mulching of the disturbed surface may not be desirable,
and its use declined, at the discretion of the Authorized Officer.
3.2.5.1 Mulch as Temporary Erosion Control
Application of mulch for temporary erosion control is based on slope surfa-ie
type and condition (ie., sand, clay, rock, etc.), slope steepness, and the amount of
exposed surface area not covered by plant residue.
During construction, water or non-toxic, organic tackifier will be applied, at the
Environmental Inspector's direction, to topsoil storage mounds composed of soils
with high wind erodibility. Tackifier will not be applied within 100 feet of a
watercourse or wetland. Stored topsoil will be tackled at 120 pounds/acre with a
non-toxic, organic tackifier, where determined by the Environmental or
Construction Inspector.
If reclamation and seeding is deferred more than 30 days after final grade
restoration near waterbodies or wetlands, all disturbed slopes above the
waterbody or wetland will be temporarily stabilized by applying 2000
pounds/acre of straw mulch (crimped or tackified) for a minimum distance of 100
feet above the edge of the waterbody or wetland. Similar temporary stabilization
may be used on slopes steeper than 30 percent. Interim seeding may be performed
as determined by the Environmental Inspector in consultation with the BLM
representative. Seedbed preparation, including thinning or removal of the mulch,
will be repeated as necessary prior to application of the fmal seed mix.
3.2.5.2 Mulch as Permanent Erosion Control
After final restoration and seeding, permanent mulch applications will be applied
to slopes greater than 30 percent, slopes within 100 feet of waterbodies and
wetlands, and other sensitive sites (dry, sandy, steep slopes, etc.) to control
erosion as determined by the BLM field representative, or the Environmental and
Construction Inspectors.
Where approved by the landowner or BLM and Environmental Inspector, the
(contractor will randomly distribute any windrowed shrubs or other remaining
vegetation debris over the ROW. Large unmerchantable trees on federal lands
may be, as directed by the agency representative, placed on the ROW. to provide
slope stabilization and erosion control benefits. On steep slopes and other areas
where broadcast rather than drill seeding must be employed, trees and shrubs will
be spread or placed during final cleanup and prior to seeding. Where
redistribution of adequate mulch from re -spread woody debris occurs, mulch rates
may be reduced or eliminated at the direction of the Environmental Inspector and
BLM field representative.
3.2.5.3 Straw Mulch
Straw will be anchored into the seedbed using a mechanical crimper specifically
designed to crimp mulch to a depth of 2 to 3 inches. The straw will be crimped
perpendicular to slope unless otherwise determined by the Environmental
Inspector and BLM field representative. Acceptable straw mulch crimpers
include:
• Mechanical crimper,
• Backhoe with crimper forks,
• Tracked equipment tracking across slopes (restricted to areas where other
methods will not work),
• Hand -punching with round -pointed shovel, or
• Equivalent approved by the Environmental Inspector and agency field
representative.
Organic liquid mulch binders may be used in accordance with manufacturer's
recommendations. If a straw mulch blower is used, strands of the mulching
material will be at least 8 inches long to allow anchoring.
3.2.5.4 Wood Fiber Mulch
Wood fiber mulches will be made of 100 percent wood fiber or equivalent
approved by the Environmental Inspector. These will be applied by a hydro
seeder with non-toxic, organic tackifier (except within 100 feet of a waterbody or
wetland) such as a guar -based tackifier, or equivalent approved by the
Environmental Inspector. -
3.2.6 Erosion Control Matting
Erosion control matting will be installed after final grade restoration to reduce rain
impacts on soils, to control erosion, and to stabilize steep slopes and waterbody banks,
where determined by the Environmental or Construction Inspector. Erosion control
matting will typically be used on streambanks and short, extremely steep sections of the
ROW where aggressive erosion control is required.
On all installations, mat will be furnished in continuous rolls of 30 feet or greater with a
minimum width of 4 feet. Staples will be made of wire, 0.091 inch in diameter or
greater, and have a "U" shape with legs 8 inches in length and a 2- inch crown. Wire
staples will be driven into the ground for the full length of the staple legs. Alternately,
wood pegs (1/2 -inch diameter) may be used to secure the erosion control fabric. In areas
of livestock grazing, other measures must be taken (see Reclamation Plan).
Installation and stapling of erosion control matting will follow procedures as
approved by the Environmental Inspector and BLM field representative. For
streambank installations, mats will be laid parallel (upper mat overlapping lower
mat in a shingle pattern) to the waterbody to a point above the top of the bank.
The erosion control mats identified above for streambank stabilization are
designed to llandle flow and can be placed under the ordinary high water mark of
the streamb--Lnk. However, matting should not be placed below this mark on
federal lands. unless it is part of an overall design using other materials to rebuild
the streamba.nk. Native materials (rocks, logs, etc.) may be used in conjunction
with the matting to aid in stabilization of banks.
During regullar erosion control monitoring, erosion control matting will be
inspected for washouts, adequate staking, and loss of matting. Damaged or
undermined matting will be repaired or replaced as necessary.
3.3 DUST CONTROL
Dust control will be implanted by the Contractor in areas of active construction within
500 feet of highways and residences (unless waived by the owner). Dust control will also
be implemented on access roads, and as determined by the Company or as required by the
Contractor for the health and safety of employees. Dust control will be achieved
primarily through application of water or an approved dust palliative. Application rates
for the dust palliative will follow the manufacturer's recommendations. All dust
palliatives used should be biodegradable unless the only way to achieve adequate dust
control is by using a non -biodegradable palliative such as magnesium chloride (MC70).
Magnesium chloride: will not be used in areas where prohibited by the landowner.
4. MONITORING AND MAINTENANCE
The Contractor will be responsible for ensuring that erosion control measures are fully functional
and for continually monitoring erosion control measures along the ROW and completing timely
repairs of erosion control structures as needed.
In addition, the Environmental Inspectors will be trained and knowledgeable in erosion and
sedimentation control methodologies, and will inspect erosion control measures along the ROW
as a part of normal daily inspection tasks. The Environmental Inspectors will identify needed
repairs and notify the Contractor who will then complete the repairs within 24 hours of
notification.
4.1 CONSTRUCTION MONITORING
Throughout construction, temporary erosion control structures will be inspected daily in
areas of active construction or equipment operation, and in all areas within 24 hours of
each 0.5 -inch or greater rainfall event, soil and weather condition permitting.
The Environmental Inspector will monitor U.S. Weather Bureau reports and notify the
Contractor of impending storm advisories. In the event of impending heavy precipitation
(e.g., the U.S. Weather Bureau issues a storm advisory for the work area), the Contractor
will reinstate temporary erosion control devices where needed (e.g., areas considered to
have greater potential for erosion, areas where cattle may have damaged erosion control
measures, and areas of active construction) to ensure that erosion control measures have
not been damaged since the last inspection. All temporary erosion control devices found
needing repair or new installation will be repaired immediately. During this period the
Contractor will provide additional personnel, vehicles and materials to repair erosion
control structure damage where noted during the inspection.
Should structures clog, deteriorate, fail, be damaged, or require maintenance, the
Contractor will conduct repairs or replacements within 24 hours after problems have been
identified, weather and soil conditions permitting.
4.2 POST -CONSTRUCTION MONITORING
Prior to the completion of construction, the Contractor and Company will verify that all
erosion control devices are in place and functional. During the first spring following
construction (after snow melt), the Company will conduct surveys to evaluate the
stability of the ROW, revegetation progress, and the success of the erosion and sediment
control structures. Assessments will be done to evaluate revegetation success and the
presence of erosion indicators such as rills, gullies, etc. If erosion control structures fail
or require maintenance, or if accelerated erosion is observed, the Company will conduct
remedial actions as soon as possible, recognizing weather and soil conditions, and site
accessibility. Remedial actions could include supplemental seeding, installation of
additional erosion/sediment control materials, maintenance of existing erosion control
measures, additional mulching, or use of matting.
4.2.1 Post -Construction Maintenance of Temporary Erosion Control Measures
Temporary sediment devices not removed by the Contractor during subsidence
and/or reseeding activities in the spring and/or summer of 2003 will be
maintained by the Company until revegetation has been determined successful.
Erosion control monitoring and maintenance efforts will continue after project
construction until successful revegetation is achieved as defined in the
Reclamation Plan. Throughout the first year following construction, erosion
control devices will be checked at all locations along the ROW in combination
with reclamation and revegetation surveys. Permanent erosion control structures
and materials including waterbars, rock rip -rap, and matting will be monitored
and maintained to ensure successful stabilization of steep slopes and stream
crossings.

I. INTRODUCTION
This Stream Crossing and Wetland Protection Plan (plan) describes measures to be taken by the
EnCana Gathering Services (U.S.A.) Inc. (Company) and its contractors (Contractor) for
construction activities in and around streams, rivers, and wetlands. No rivers, wetlands, or
perennial streams will be crossed on federal surface managed by BLM.
1.1 PURPOSE OF PLAN
This plan covers, and is designed to minimize the environmental impacts to all
jurisdictional wetlands, flowing streams, river crossings (waterbodies), and dry stream
crossings.
1.2 RESPONSIBILITIES
1.2.1 Company
The Company will be responsible for meeting the goals and objectives of this plan
and for ensuring that the Contractor uses the methods described in this plan. The
Company will also ensure that environmental oversight of the project includes
preconstruction marking/flagging of all flowing streams, rivers, and wetlands as
described in Section 2.2. The Environmental Inspector will ensure that the
Contractor constructs through sensitive resources as required in this plan and will
also ensure that all warking/flagging remains in place and is visible throughout
construction.
The Company will, prier to any ROW clearing and grading, ensure that the
Contractor has sufficient environmental protection supplies and materials on hand
to initiate installation of erosion control devices. The Company will ensure that
the environmental protection supplies meet the specifications contained in this
plan and other related plans as listed in Section 1.4. This includes straw bales, silt
fence, erosion control matting, hazardous substances spill clean up equipment,
and other materials.
1.2.2 Contractor
The Contractor will be responsible for implementing the methods prescribed in
this plan to meet site-specific conditions. The Contractor will ensure that all
methods employed are installed and maintained correctly. It is the Contractor's
responsibility to monitor the effectiveness of the installed devices and to correct
any conditions that do not meet the requirements of this plan.
The Contractor will be responsible for ordering and maintaining an inventory of
environmental control supplies and materials to meet daily construction
requirements as well as meeting emergency conditions.
1.3 DEFINITIONS
Waterbody: Includes any natural or artificial stream, river, or drainage with perceptible
flow at the time of crossing, and other permanent waterbodies such as ponds (both natural
and stock ponds) and lakes.
Minor Waterbody: Includes all waterbodies less than or equal to 10 feet wide at the
water's edge at the time of construction.
Intermediate Waterbody: Includes all waterbodies greater than 10 feet wide but less than
or equal to 100 feet wide at the water's edge at the time of construction.
Major Waterbodv: Major waterbodies are defined as flowing streams and rivers that are
greater than 100 feet wide at the water's edge at the time of construction.
Wetland: Includes any . area that satisfies the requirements of the current federal
methodology for identifying and delineating wetlands.
1.4 RELATED PLANS AND DRAWINGS
The following documents include additional requirements specifically relating to
construction at waterbodies and wetlands and are referenced throughout this plan.
• Hazardous Materials Management and Spill Prevention and Countermeasure
Plan
• Reclamation Plan
2. CONSTRUCTION METHODS
Specific construction methods will be determined by the Contractor utilizing the
requirements of this plan as the minimum acceptable standards.
2.1 DRY STREAMS
The following requirements for crossing flowing streams and wetlands do not apply to
dry streams and drainages. Dry stream and drainage crossings will be constructed using
the same construction methods that will be used along the rest of the ROW, except that
spoil will be placed outside the channel to provide unrestricted drainage across the ROW:
The Company Environmental Inspector will assist the Contractor, where necessary, in
determining the limits of the dry channel. In wide channels, gaps may be left in the spoil
piles to allow for the required drainage. During cleanup and reclamation, the
preconstruction profiles and contours (including meanders of the streambed) of dry and
intermittent streams will be re-established.
2.2 MARKING AND FLAGGING
The Company will sign and/or flag the following boundaries at least 72 hours prior to any
clearing or grading, or before any construction crew is within 1 mile of any site requiring
signs and/or flagging.
• 75 -foot limits of the ROW in waterbodies and wetlands (survey flagging)
• Edges of wetland boundaries ("Wetland Boundary" sign)
Limits of 100 -foot buffers for fueling and concrete coating activities ("No
Refueling" sign)
• 10 -foot buffers from the water's edge for spoil storage ("No Spoil Storage
Beyond This Point" sign)
No activities are permitted outside of approved work areas.
2.3 HAZARDOUS MATERIALS
The Contractor will comply with the requirements included in the project's and the
Contractor's Hazardous Materials Management and Spill Prevention and Countermeasure
Plans Contractor will not store haryardous materials, chemicals, fuels, lubricating oils, or
perform concrete coating activities within 100 feet of any waterbody or dry drainage, or
within any designated municipal watershed area (except at locations designated for these
purposes by the BLM and/or Environmental Inspector). Equipment or vehicles that are
crossing or working within 100 feet of waterbodies will not be refueled unless a specific
exception is given by an Environmental Inspector. If any hazardous materials must be
temporarily stored or transferred within 100 feet of a stream (i.e. stationary pumps), then
it must be placed within a secondary containment structure as specified in the Hazardous
Materials Management and Spill Prevention and Countermeasure Plan.
2.4 CLEARING AND GRADING
Clearing and grading at waterbody crossings will be limited to that needed to construct
the crossing. During clearing, the root systems will be left in place except over the trench
line and in areas that require grading. Root systems may also be removed along the
travel lane as determined necessary by the Environmental Inspector to allow safe passage
by rubber tired vehicles. Removal of root systems over the travel lane to allow safe
vehicle access in areas that do not require grading will require a variance on federal
lands. Grading will be limited to the trench line, the banks of streams, and locations with
side slopes. Grading within 50 feet of stream banks is restricted to that needed for the
equipment crossing, until construction of the actual pipeline crossing has begun.
Prior to or immediately after any ground disturbing activity, temporary sediment control
devices such as silt fence and straw bales will be installed at the base of all slopes leading
to waterbodies in accordance with the project's Soil Conservation, Sedimentation, and
Erosion Control Plan. The Contractor will maintain these devices in functioning order
until construction activities, including reclamation activities, have been completed.
2.5 VEHICLE AND EQUIPMENT CROSSING
2.5.1 Waterbodies
Only clearing equipment may cross waterbodies prior to the installation of an
equipment bridge. Waterbody fording by clearing equipment is limited to one
crossing per piece of equipment. Fording will not be used as a crossing method
for other vehicles or equipment.
Equipment bridges will be one of the following types:
• portable bridges that span the channel
♦ flume(s) and clean rock riprap (with a 20inch minimum diameter)
♦ timber equipment mates (installed above the waterline) used as a bridge over
small waterbodies
Each bridge will be designed to allow for the maximum predicted flows for the
time frames that it will be in place, including all expected precipitation events.
The Contractor will also maintain bridges so that soil from equipment or the
bridge abutment is prevented from entering any waterbody.
All equipment bridges will be removed as soon as possible after permanent
seeding.
2.5.2 Wetlands
If the wetland is dry, equipment can use the ROW for access on an as -needed
basis with as much traffic as possible routed around the wetland.
For wetlands with standing water or saturated soils the equipment operating in the
wetland will be limited to that needed to construct the wetland crossing. The
ROW will not be used as an access route unless it is the only possible method of
access.
Foreign material (upland soil, rock, tree stumps, etc.) will not be imported into the
wetland to stabilize the working area. If standing water or saturated soils are
present, equipment will work from, and access across, timber equipment mats.
2.6 WATERBODY INSTALLATION METHODS
There are three general construction methods for installing pipelines across waterbodies:
1) Dry Trench Method: routing the flow around the trench during trench excavation,
installation of the pipeline and backfilling.
2) Open -Cut Method: allowing the stream flow to continue though the work area during
trench excavation, installation of the pipeline, and backfilling.
3) Directional Bore Method: allowing the pipeline to be pulled into a subsurface bore
hole which results in no surface disturbance.
Contractor will use the directional bore method on all major crossings unless otherwise
dictated by BLM.
2.6.1 General Requirements
The following requirements apply to all waterbody-crossing methods.
♦ Bore pits will be kept to a minimum size
• Spoil storage from pit excavations will be at least 10 feet from the water's
edge and will be located behind sediment barriers.
• Drilling fluids will be dept contained at all times.
2.6.2 Open Cut Construction: Minor and Intermediate Waterbodies
The open cut method applies to minor and all intermediate waterbody crossings.
Grading and trenching of the ROW adjacent to (upslope of) the stream banks, and
fabrication and weighting of the pipe section for the crossing will be completed
prior to in -stream trenching. Topsoil will be salvaged from the stream banks prior
to grading and trenching. If topographic conditions allow, a hard plug will be left
in place slightly above the stream level. Trenching will then begin from the
approximate steam center toward the remaining bank material or bard plugs on
either (or both) side(s) with all spoil piles stored a minimum of 10 feet from the
water's edge and behind sediment barriers or other containment structures.
After the pipe has been installed, trench soft plugs will be placed as close to the
water's edge as possible to prevent upland backfill material and ground water
from entering the waterbody. The upland sections of the trench will then be
dewatered into an upland area so that the tie-in and backfilling procedures can be
completed in a fairly dry condition. The in -stream trench will then be backfilled
with previously excavated material and the channel bottom and banks restored.
2.7 WETLAND CROSSING METHODS
2.7.1 Dry Conditions
Prior to trenching all topsoil up to 12 inches in depth, as determined by the
Environmental Inspector, will be stripped from over the trenchline. If the wetland
is located on a sidehill, topsoil will be stripped from the entire area being graded.
Topsoil will be stockpiled in a location where it will not be mixed with any
upland soils or wetland subsoil. Care will be taken to ensure that the area stripped
over the trenchline is wide enough to include topsoil over trench sidewalls that
may slough off due to high ground water. Sediment barriers will be installed
between the spoil piles and the edge of the ROW, where the Environmental
Inspector determines that there is a potential for material to leave the ROW. If
dewatering is required, the requirements described in Appendix "B", Section
3.2.4, will be followed.
2.7.2 Standing Water or Saturated Soil Conditions
If possible, as determined by the Environmental Inspector, all topsoil up to 12
inches in depth will be removed and stockpiled as directed above in Section 2.7.1.
Timber equipment mats, if needed, will be the method of stabilizing the work
area Sedimentation barriers will be placed on the down-slope edge of the ROW
if the wetland continues beyond the ROW or both edges of the ROW is flat and
there is a potential for material to leave the ROW.
The drag section needed for each wetland crossing will be built in an upland area.
If the wetland working space is stable, as determined by the Company
Construction and Environmental Inspector, oris short (less then 200 feet), normal
construction techniques utilizing equipment mats will be used for construction.
For unstable conditions in larger saturated wetlands a float technique will be used
to lay the pipe.
Tie-in locations will be in upland areas, if possible, with a soft trench plug
between the tie-in location and the wetland. Tie-in locations that require
dewatering will use a dewatering structure that is located outside the wetland
boundary, so that no heavily silt -laden waters reach any waterbodies or wetlands.
If trench dewatering is required, implement measures described in Appendix "B",
Section 3.2.4.
3. EROSION CONTROL AND RESTORATION
3.1 EROSION CONTROL
Immediately after initial ground disturbance, temporary erosion control measures will be
installed. This will include at a minimum, sediment barriers at the base of all slopes
along the ROW leading to waterbodies and wetlands. All temporary controls will be
maintained until permanent erosion control is in place as defined in the Soil
Conservation, Sedimentation, and Erosion Control Plan. After pipe installation, trench
breakers will also be placed at the base of slopes leading to waterbodies and where
groundwater may migrate along the trench. Waterbars will be placed just below the
trench breakers to cavy off any excess water into vegetated areas.
Streambanks and other steep slopes around waterbodies may require additional
stabilization beyond the replacement of original contours and other normal erosion
control requirements (as described in the Soil Conservation, Sedimentation, and Erosion
Control. Plan). Stabilization of stream banks with on-site materials (e.g. placing felled
trees along the streambanks) will be determined on site by the BLM's field representative
and with appropriate permit approvals. Erosion control matting may be required for
stabilization above the high water mark for streambanks over 50 percent slope and as
directed by the Company. The matting will extend up the banks 100 feet or until the
slope is less than 50 percent, whichever is less. Installation and stapling of erosion
control matting will follow procedures specified in the details. For streambank
installations, mats will be laid parallel (upper mat overlapping lower mat in a shingle
pattern) to the waterbody to a point above the top of the bank. As mentioned above,
native materials (rocks, logs, etc.) may be used in conjunction with the matting to aid in
stabilization of banks. Below the high water mark, clean riprap may be used on stream
banks, as directed by the Company, to prevent bank erosion. Contractor may use excess
rock obtained from the ROW for rip-rap, if rock is of sufficient quality and quantity as
determined by the Company, or will obtain rock from an approved commercial source.
3.2 RESTORATION
Original meanders, profiles, cross-sections, and other contours of waterbodies and 25 feet
up each stream bank will be restored, fmal cleanup concluded, seeding accomplished, and
mulching or erosion control mats installed, prior to the end of the following time frames,
unless otherwise authorized by the Company (private lands) and/or the BLM agency
representative (federal lands).
• minor streams - 24 hours after initial in-stream disturbance
♦ intermediate streams - 72 hours after initial in-stream disturbance
♦ wetlands - 10 days after backfilling
There are exceptions to these time frames.
• Temporary bridges or other materials (e.g. timber mats) required for access
will not have to be removed until they are no longer needed. All other areas
at the crossing, not needed for the bridge abutments, must meet the
requirements above.
• Very steep or incised stream/river banks with the likelihood of further erosion
will not have the original contour restored. These stream/river banks will be
restored at a 1.5 to 1 slope (horizontal to vertical), which is equivalent to 67
percent slope. Transition from adjacent slopes, to those reclaimed over the
ROW, will be made so as to prevent erosion between these transitions, and to
minimize eddying at the tie of these slopes.
If reclamation and seeding is deferred more than 10 days after final grade restoration near
waterbodies and wetlands, all disturbed slopes above waterbodies and wetlands will be
temporarily stabilized by applying straw mulch for a minimum distance of 100 feet above
the edge of the waterbody or wetland.
Fertilizers, herbicides, and lime will not be used within 100 feet of waterbodies.

1. INTRODUCTION
The Hydrostatic Testing Plan (plan) identifies measures to be taken by the EnCana Gathering
Services (U.S.A.) Inc. (Company) and its contractors (Contractor) to ensure that hydrostatic
testing operations are carried out in accordance with the following:
• United States Department of Transportation Code of Federal Regulations (CFR),
Title 49, Part 192, Subpart J, entitled "Test Requirements"
• Environmental Protection Agency
• Colorado: Department of Public Health — Water Quality Control Division
• Colorado: Department of Natural Resources — Division of Water Resources
Measures identified in this plan apply to work within the project area defined as the right-of-way
(ROW) and other areas used during hydrostatic testing of the pipeline.
2. PURPOSE
The purpose of this plan is to ensure that necessary measures are implemented during hydrostatic
testing of the pipeline to ensure the safety of all pipeline construction personnel and the general
public. This plan also identifies measures relating to water quality that will be implemented
during withdrawal and disposal of hydrostatic test water.
This plan describes safety standards and practices that will be implemented during construction
of the project to minimize health, safety, and environmental concerns related to hydrostatic
testing on the project.
3. HYDROSTATIC TESTING PROCEDURES
The following procedures will be implemented by the Contractor during hydrostatic testing
operations. This section of the plan describes pre -testing requirements, the typical sequence of
activities associated with hydrostatic testing operations, and notifications required by the
Contractor and Company.
3.1 PRE -TESTING REQUIREMENTS
3.1.1 Permits
The Company is responsible for securing water permits from the governing
authorities for the use and disposal of test water. The company will also comply
with the rules and regulations of the Colorado Department of Public Health and
the Department of Transportation (DOT).
The Company will procure water from a private potable water supply at an
EnCana Gathering Services (U.S.A.) Inc. facility. The test water discharged by
the Contractor will be in compliance with regulatory notification requirements
and sufficient notice will be provided to the Company's Testing Inspector to make
water sampling arrangements, as necessary. Under no circumstances will an
alternate water source be used without prior authorization from the Company.
There will be no discharge location on private land. Discharge test water will be
collected into portable storage tanks The test water will be filtered then hauled
offsite to approved disposal sites. This discharge will be land based and will not
result in a discharge to a "water of the United States." Therefore an NPDES
permit will not be required.
3.2 HYDROSTATIC TEST PROCESS
3.2.1 Water Sampling
Hydrostatic test water sampling will be performed in accordance with permit
requirements. The Company's Environmental Inspector will be responsible for
obtaining any required water analyses form each source to be used in sufficient
time for the Company to have a lab analysis performed prior to any filling
operations.
Whenever water sampling is required, sample bottles will be obtained from a
certified testing laboratory. Analysis of the samples will be in accordance with
permit requirements. Each bottle will be marked with:
• source of water with pipeline station number,
• date taken,
• laboratory order number, and
• name of person taking sample.
The Company's Environmental Inspector will be notified at least one day prior to
obtaining water and/or discharging water and the Contractor will provide the
Environmental Inspector access for sampling.
3.2.2 Discharge Locations
There will be no discharge location on private land. Discharge test water will be
collected into portable storage tanks. The test water will be filtered than hauled
offsite to approved disposal sites. This discharge will be land based and will not
result in a discharge to a "water of the United States." Therefore an NPDES
permit will not be required. All discharge will be done in accordance with all
applicable permit conditions and state requirements.
3.2.3 Pumps
If pumps for hydrostatic testing are within 100 feet of any waterbody or wetland,
secondary containment measures (such as bermed depressions lined with visqueen
plastic, plastic troughs, or other containment structure) will be implemented to
prevent any spilled fuels or oils form reaching the waterbody or wetland.
3.2.4 Safety Measures
The Contractor will provide for the safety of all pipeline construction personnel
and the general public during hydrostatic test operations by:
• placing warning signs in populated areas;
• restricting access to the immediate area involving the hydrostatic test (i.e.,
test shelter, manifolds, pressure pumps, instruments, etc.) to only those
personnel engaged in the testing operations;
• prohibiting major pipeline work not directly associated with the test
operations around the pipeline sections being tested. (While the pipeline
facilities are being pressurized and during the test all personnel not required
for direct operations (check for leaks, tighten gaskets, check valve status,
operating pumps, recording data, etc.) will be restricted from the area where
the pipeline is being tested;
• providing and maintaining a reliable transportation and communication
system during the test operations whereby all personnel directly involved in
the test will be able to conununicate test status or problems that develop
during the test;
• checking all hoses, fittings, connectors, and valves for proper pressure rating;
• restraining and securing fill and discharge lines/hoses; and
• having their radiographic inspection subcontractor nondestructively inspect
all temporary welds subject to hydrostatic test pressure.
3.2.5 Cleaning the Pipeline
Upon completion of the pipe lowering and backfilling operations for each test
section of the pipeline and prior to filling and pressure testing, the Contractor will
clean the pipeline by running cleaning pig(s) using compressed air to propel the
pig(s). The pig(s) will be run completely through the pipeline test section. The
Company's representative will be present to approve the cleanliness of the line.
The Contractor will run the brush pigs and squeegees continuously through the
line until all solids, dust, and mill scale are removed, unless otherwise approved
by the Company's representative. Company's representative will be present for
the first and last brush pig run to compare their respective conditions. No red dust
will be blowing out of the line when the final brush pig is run. This will assure
that all rust has been removed from the interior walls of the pipeline. Foam
squeegees will be run after the final brush pig run to enhance the removal of dust
mill scale.
3.2.6 Filling the Pipeline
Prior to filling a test section with water, the Contractor will make a final check to
verify the following:
• valve body drain plugs have been removed, carefully cleaned, taped
(Teflon) and replaced;
• all mainline valves are in open position;
• valves have been greased, stroked, and the packing tightened; all pipe
and bolt connections are tight;
• test manifolds are properly fabricated and tested;
• pumps and compressors are in good working condition;
• instruments are ready for use (propercharts installed, ink pens filled,
clocks wound, correct calibration, etc.); and
• pigs are properly installed.
The water pumps will be set on a metal or polyethylene catch pan of sufficient
dimensions to contain all leaking lubricants or fuel and prevent them from
entering the water source. The suction inlet will be placed in a 100 mesh screened
enclosure, to prevent fish entrapment, located at a depth that will not allow air to
be drawn in with the water. A rock -lined sump will be installed, if necessary, to
prevent intrusion of sediment.
3.2.7 Testing the Pipeline
The official test duration will be 8 hours minimum with the pressure maintained
at the minimum specified at all points in the pipeline section. The test will be
accepted upon proof of no leakage.
In the event of break during testing, the break will be repaired as. directed by the
Company and the above test repeated until a satisfactory test is obtained on the
section.
3.2.8 Depressurizing the Pipeline
As soon as possible, after the test has been presented by the Contractor as a
successful test and accepted by the Company Testing Inspector the pipeline will
be depressurized.
3.2.9 Dewatering the Pipeline
The Contractor will be responsible for the discharge of test water in accordance
with the governing permits and/or private landowner requirements. The
Contractor will discharge the water into frac storage tank in order to dissipate
energy from test water velocity. The water will then be hauled to offsite disposal
systems.
1
3.2.10 Drying the Pipeline
Following the dewatering of individual pipeline sections, these sections will be
cleaned of loosely adhered mill scale, rust, dirt, and other debris.
3.3 RECORDS
The Contractor will keep and furnish complete records of all phases of the testing
program including recording charts, deadweight log, pressure, temperature (both pipe and
ambient) and weather conditions, and make, style number, and conditions of all pigs used
in filling and dewatering.

1. INTRODUCTION
This Reclamation Plan (plan) describes measures to be taken by EnCana Gathering Services
(U.S.A.) Inc. (Company) and its construction contractors (Contractor) for topsoil restoration,
reseeding, planting, noxious weed control and reclamation monitoring.
1.1 PURPOSE
The purpose of this plan is to describe in text and on drawings the prescribed methods for
topsoil replacement, reseeding, planting noxious weed control, and monitoring for
reclamation success. This plan is applicable to the construction on right-of-way (ROW)
and extra workspace locations.
1.2 GOALS AND OBJECTIVES
The short-term goals of reclamation are to control erosion and sedimentaiiioonncan ano
optimum impactsto
adjacent land
short-termly grtermongoals include
optimum scheduling protecting water resources and soils; limiting the
controlling erosion and sedimentation; p
introduction and spread of noxious weeds; and returning disturbed areas to pre-existing
condition. Monitoring during construction and post -construction will ensure that these
goals are achieved.
1.3 ENVIRONMENTAL TRAINING
The Company will conduct environmental training for all project personnel. Training
will include topsoil protection measuresand methods and entor controlling the spread of
noxious weeds (e.g., maintaining
clean 1.4 RELATED PLANS / MAPS
The following documents include additional requirements specifically related to the
reclamation of the ROW and ancillary areas:
♦ Soil Conservation, Sedimentation, and Erosion Control Plan
• Stream Crossing and Wetland Protection Plan
♦ Hazardous Materials Management and Spill Prevention and Countermeasure Plan
• Alignment Sheets
1.5 RESPONSIBILITIES
Responsibilities are detailed below:
1.5.1 The Company
The Company will be responsible for ensuring that the Contractor meets the
standards defined in this plan to restore all disturbed areas to pre -construction
conditions and to ensure long-term monitoringof
restoration
success.in st he
e
Company will take remedial actions as necessary to restore
vegetative cover on the ROW. The Company will provide the Contractor with the
appropriate blended seed mixes developed through consultation with agency
representatives and landowners.
1.5.2 The Contractor
The pipeline Contractor will be responsible for post -construction re -seeding of the
ROW, extra workspaces, and off -ROW ancillary sites following their construction
activities. Reclamation will be conducted according to this plan as specified for
the Contractor.
1.5.3 The Environmental Inspector
The Environmental Inspector will have the responsibility to ensure field activities
are performed in accordance with this reclamation plan by the Contractor and in
compliance with all other permits and agreements. The Environmental Inspector
will have the authority to make site-specific field changes in certain reclamation
procedures within the guidelines of this plan in consultation with the landowner or
BLM.
2. RECLAMATION PROCESS
The following sections outline the pre -construction planning and sequential steps for restoring
the ROW and extra workspaces following installation of the pipe and backfilling of the trench.
However, one of the most important factors relating to successful reclamation takes place during
the initial grading of the ROW. Topsoil salvage requirements and methods are discussed in
detail in the Soil Conservation, Sedimentation, and Erosion Control Plan.
2.1 RECLAMATION ACTIVITIES
The Environmental Inspectors with the BLM, Soil Conservation Authority and
Landowners will work to determine depth of topsoil salvage, appropriate seed mixes, and
seeding methods.
2.2 ROCK DISPOSAL
"Excess rock" is defined as all rock that cannot be returned to the existing rock profile in
the trench or graded cuts, or is not needed to restore the ROW surface to a condition
comparable to that found adjacent to the ROW. This does not include tailings from
boring operations. (NOTE* Absolutely no tailings from the proposed boring areas will
be spread or stored on federal land) Excess rock will be randomly distributed across the
ROW, piled or windrowed to create or enhance wildlife habitat, or arranged to block use
of the ROW by motor vehicles. If not practical, the Contractor will remove other excess
rock from the ROW and haul it to an approved disposal site. The Company will
coordinate with landowners or the BLM regarding the methods of disposal.
2.3 FINAL CLEANUP
Within 30 days after backfilling the trench, the Contractor will make every effort to
complete final cleanup and installation of permanent erosion control structures. If
circumstances prevent achieving cleanup within 60 days on federal lands, the Company
will, apply for a variance from the BLM.
The ROW and other project -related areas where soil has been disturbed will be restored
as close to pre -excavation grades, compaction, and other conditions as possible, unless a
specific exemption has been granted by the landowner or BLM No solid waste, trash, or
vegetative matter will be buried on the ROW.
Final compaction of disturbed areas will be returned to approximate pre -construction
conditions. In cases where this is not possible, e.g., steep slopes or rocky areas where
full- ROW width topsoil salvage was not required, compaction will not vary more than
10 percent from adjacent off -ROW conditions. The Company will test soil compaction to
a depth of 18 inches, if possible, at regular intervals using band -held penetrometers or
equivalent testing equipment and procedures.
The Contractor will take remedial action as directed by the Company at all locations
where compaction is not within the previously described 10 -percent limit. The
Contractor will decompact excessively compacted areas with a paraplow, "Vibrashank,"
or other deep tillage implement. In areas where topsoil has been segregated, the subsoil
will be decompacted prior to re -spreading the topsoil.
In areas with a pre-existing rocky surface material, the Contractor will spread rock over
the ROW to maintain a surface appearance similar to that of adjacent undisturbed terrain.
Spreading rock on the surface will not be used as a method to dispose of excess rock
except as described in Section 2.2.
Where approved by the landowner or BLM and environmental Inspector, the Contractor
will randomly distribute any windrowed shrubs or other remaining vegetation debris over
the ROW. However, this must be accomplished by hand or light equipment (e.g., all -
terrain vehicles) after seeding of the ROW so the spread material will not interfere with
the performance of seeding equipment and to prevent disturbance of the seedbed.
2.4 TOPSOIL RESTORATION
After the trench has been backfilled and the ROW regarded, the Contractor will
redistribute topsoil to the approximate location from which it was originally removed.
Restored topsoil will be left in a roughened condition to discourage erosion and enhance
the quality of the seedbed Topsoil will not be handled during excessively wet or frozen
conditions as determined by the Environmental or Construction Inspector.
Topsoil will be redistributed as close to original salvage depths as possible. Salvage
methods are discussed in Section 2.2 of the Soil Conservation, Sedimentation, and
Erosion Control Plan. Segregation of subsoil and topsoil will be maintained throughout
final cleanup procedures. The Contractor will be responsible for replacement of lost or
degraded (mixed) topsoil with topsoil imported from a Company -approved and weed -free
source.
Additional erosion control and soil stabilization will be required in areas adjacent to or
within drainages. See the Soil Conservation, Sedimentation, and Erosion Control Plan
and the Stream Crossing and Wetland Protection Plan for additional information.
2.5 MISCELLANEOUS AGRICULTURAL FEATURES
All irrigation ditches, drain tiles, cattle guards, fences, and artificial and natural
livestock/wildlife water sources will be maintained and repaired to at least pre-
construction
ro-construction conditions. Temporary measures will be provided, as agreed with the
Landowner or BLM, for any of these facilities that are disrupted during the construction or
reclamation process.
All drain tiles crossed by the trench line will be located and restored to the satisfaction of
the landowner. Since the exact location or even the existence of drainage system may not
be known prior to excavation, all drain tiles unearthed during excavation by the
Contractor will be reported to the Company in writing.
2.6 SEEDBED PREPARATION
The Contractor will scarify, till, or harrow the seedbed to a depth of 3 to 4 inches or as
determined by the Environmental Inspector prior to seeding where needed to improve
revegetation potential. Those sites where seedbed preparation is not practical (e.g., steep
slopes, rocky areas, etc.) will be left with adequate roughness following topsoil
placement to create micro -environments for seed gemination and growth, and to reduce
the potential for soil movement.
2.7 SOIL. SUPPLEMENTS
Generally, fertilizer will not be used unless requested by the landowner or recommended
by either the Environmental Inspector or a soil conservation authority. At this time, no
areas have been identified that require fertilizer.
2.8 REVEGETATION
The Contractor will be responsible for seeding the ROW and off -ROW ancillary sites
using Company -supplied seed mixes, appropriate seeding methods, and approved
application rates. The seeding requirements and scheduling of reclamation activities will
be determined in coordination with BLM, Soil Conservation Authority or the appropriate
landowner.
2.8.1 Species Selection and Sources
Selection of grass and shrub species for revegetation will be based on pre -
construction community composition and soil types as well as establishment
potential, soil stabilizing qualities, commercial availability of regional varieties,
post -construction land use objectives, and agency recommendations. Native
species will be utilized to the extent possible unless non -natives are specifically
requested by a private landowner or land managing agency. Project seed will be
purchased from the blended by qualified producers and dealers.
Certified weed -free or "blue -tagged" seed will be purchased for use on the
project, but this status is only available for those native species with named
varieties. All other seed will be free of primary noxious weeds. EnCana
Gathering Services (U.S.A.) Inc., will submit the seed for independent testing
prior to its use. The Contractor will be responsible for providing all seed tags to
the Environmental or Construction Inspector at the end of each day.
On BLM, the following seed mix will be used:
Pounds pure live seed (PLS)/Acre
Rocky Mountain Penstemon 0.25
Arrowleaf Balsamroot 0,25
Streambank Wheatgrass 2.5
Western Wheatgrass 2.5
Thickspike Wheatgrass 2.5
Sandberg Bluegrass 2.5
Snowberry 0.5
Four -wing Saltbush 0.5
Serviceberry 0.5
Big Sagebrush 0.5
Total 12.0 lbs PLS/Acre
2.8.2 Seed Application Rates and Viability
Species ratios and Pure Live Seed (PLS) application rates will be developed in
consultation with landowners, agency specialists, and other regional revegetation
consultants. Seeding rates will be determined in PLS pounds per acre and seeds
per square foot based on drilled application rates. Broadcast seeding rates will be
twice the drill rate.
Seed will be used within 12 months of testing to assure seed viability. If
additional seeding is required in the year following construction, additional
viability test will be conducted to determine any need for adjustment of
application rates.
The Contractor will seed wetlands, when necessary as determined by the
Environmental Inspector and BLM. Successful recolonization by wetland species
is generally related to effective topsoil salvage methods and sources of seed and
rhizomes in adjacent areas.
Streambanks will be seeded immediately upon completion of final cleanup as
described in the Stream Crossing and Wetland Protection Plan and independent of
other reclamation activities,
2.8.3 Seeding Methods and Procedures
The Contractor will employ broadcast or drill seeding as determined in the field
by the Company. Seeding activities will be contingent upon weather and soil
conditions, and subject to evaluation by the Environmental Inspector. Seeding
will not be permitted if there is more than 2 inches of snow on the ground unless
approved by the Environmental Inspector and BLM field representative. Where
approved by the landowner or land managing agency, the Contractor will
randomly distribute any windrowed shrubs or other remaining vegetation debris
over the ROW by hand or light equipment so as not to disturb the seedbed.
2.8.3.1 Drill Seeding
Drill seeding will be employed wherever soil characteristics and slope
allow effective operation of a range drill. Drill seeding will be performed
perpendicular to the slope unless otherwise directed by the Environmental
Inspector and BLM field representative. The drill will have a seed release
mechanism sufficient to allow seeds of various sizes and densities to be
planted at the proper seeding depth.
2.8.3.2 Broadcast Seeding
Broadcast seeding will be employed in all areas where drill seeding cannot
be performed. Seed will be applied using manually operated cyclone -
bucket spreaders, mechanical spreaders, blowers, or hydroseeders. Seed
will be uniformly broadcast over disturbed areas. Immediately after
broadcasting, the seed will be uniformly raked, chained, harrowed, or
cultipacked to incorporate seed to a sufficient seeding depth. If it is not
possible to cover the seed with mechanical methods, the seeding rates will
be doubled.
2.9 PERMANENT EROSION CONTROL
Permanent erosion control methods will be utilized as needed for stabilization of slopes
and soils as described in the Soil Conservation, Sedimentation, and Erosion Control Plan.
Permanent erosion control measures will be installed within 30 days after the trench is
backfilled to aid in site stabilization wherever required.
3. NOXIOUS WEED CONTROL
Noxious weeds are spread through the dispersal of seeds or the transport of propagative plant
parts. It is therefore important to reduce the sources of seed and viable plant material prior to
construction disturbance and to prevent its transport or importation during construction. The
combination of methods described below will be employed to minimize the potential for
expansion of noxious weed populations via the pipeline route.
3.1 Weed Control Measures During Construction
The Company will require that all Contractor vehicles and equipment arrive at the work
site clean, to prevent the importation of noxious weeds from a previous work site. Only
after the Environmental Inspector has determined it to be free of soil, debris, or other
potential sources of noxious weeds will any piece of equipment be allowed initial
transport or access to the ROW.
4. WORKER SAFETY AND SPILL REPORTING
All contracted herbicide contractors will obtain and have readily available copies of the
appropriate application permits and the Environmental Protection Agency Material Safety Data
Sheets (MSDS) for the herbicides being used. All reasonable precautions will be taken to avoid
spilling herbicides. However, a spill kit will be carried in all herbicide applicator's vehicles to
facilitate quick and effective response to a spill, should one occur. Herbicide spills will be
reported in accordance with the requirements described in the project's Hazardous Material
Management and Spill Prevention and Countermeasure Plan.
2.8.3.2 Broadcast Seeding
Broadcast seeding will be employed in all areas where drill seeding cannot
be performed. Seed will be applied using manually operated cyclone -
bucket spreaders, mechanical spreaders, blowers, or hydroseeders. Seed
will be uniformly broadcast over disturbed areas. Immediately after
broadcasting, the seed will be uniformly raked, chained, harrowed, or
cultipacked to incorporate seed to a sufficient seeding depth. If it is not
possible to cover the seed with mechanical methods, the seeding rates will
be doubled.
2.9 PERMANENT EROSION CONTROL
Permanent erosion control methods will be utilized as needed for stabilization of slopes
and soils as described in the Soil Conservation, Sedimentation, and Erosion Control Plan.
Permanent erosion control measures will be installed within 30 days after the trench is
backfilled to aid in site stabilization wherever required.
3. NOXIOUS WEED CONTROL
Noxious weeds are spread through the dispersal of seeds or the transport of propagative plant
parts. It is therefore important to reduce the sources of seed and viable plant material prior to
constriction disturbance and to prevent its transport or importation during construction. The
combination of methods described below will be employed 'to minimize the potential for
expansion of noxious weed populations via the pipeline route.
3.1 Weed Control Measures During Construction
The Company will require that all Contractor vehicles and equipment arrive at the work
site clean, to prevent the importation of noxious weeds from a previous work site. Only
after the Environmental Inspector has determined it to be free of soil, debris, or other
potential sources of noxious weeds will any piece of equipment be allowed initial
transport or access to the ROW.
4. WORKER SAFETY AND SPILL REPORTING
All contracted herbicide contractors will obtain and have readily available copies of the
appropriate application permits and the Environmental Protection Agency Material Safety Data
Sheets (MSDS) for the herbicides being used. All reasonable precautions will be taken to avoid
spilling herbicides. However, a spill kit will be carried in all herbicide applicator's vehicles to
facilitate quick and effective response to a spill, should one occur. Herbicide spills will be
reported in accordance with the requirements described in the project's Hazardous Material
Management and Spill Prevention and Countermeasure Plan.
5. RECLAMATION SCHEDULE AND DOCUMENTATION
Reclamation activities will be determined in part by construction schedules and seasonal climatic
conditions. Seeding and planting will be coordinated with other reclamation activities to occur
as soon after seedbed preparation as possible. Ideally, the Contractor will complete permanent
reclamation activities prior to the end of the typical fall planting season (September 1st —
October 31st).
Upon completion of reclamation, the Company's Construction Inspector, Environmental
Inspector, and Land Agents, and BLM representatives will perform a final inspection of the
ROW and ancillary facilities to verify that pre -construction commitments have been satisfied. A
copy of the post -reclamation inspection form will be transmitted to the Contractor if any
deficiencies or a need for remedial action is noted.
6. POST -CONSTRUCTION MONITORING AND EVALUATION
6.1 REVEGETATION AND EROSION CONTROL MONITORING
During the first growing season following construction and reclamation, qualified
specialists will conduct intensive surveys to assess revegetation success and determine
the need for further reclamation.
Revegetation monitoring will include evaluation of the following parameters as compared
to adjacent (off -ROW) vegetation:
• percent total herbaceous cover (seeded species plus desirable volunteers), and
• species composition.
Where applicable, the following will be evaluated:
♦ new or expanded populations of noxious weeds.
Areas with poor germination and/or growth will be evaluated to determine, if possible,
the cause of the problem. Reclamation techniques will be modified as necessary to
address any identified problems and appropriate remedial measures will be undertaken.
The Contractor will be responsible for remediating any problem areas identified by the
Company for the first growing season following construction. Thereafter, the Company
will be responsible for obtaining a reclamation contractor to perform any necessary work.
Erosion control monitoring will be performed in response to significant weather events
and/or concurrently with the revegetation monitoring during the first year following
construction. Success criteria for both are discussed in Section 6.2.
Both erosion control and revegetation monitoring will be conducted routinely throughout
the life of the pipeline to evaluate long-term survival of reestablished vegetation and the
effectiveness of erosion control measures with specific attention to problem sites.
6.2 EVALUATING RECLAMATION SUCCESS
The Company is responsible for the stability and revegetation of all areas disturbed as a
result of construction for the life of the pipeline. As discussed in Section 6.1, the
Company will conduct intensive monitoring after the first growing season and routinely
thereafter to assess soil stability and revegetation success.
The Contractor will reseed any portion of the ROW that does not exhibit 50 percent total
herbaceous cover (comprised of seeded species plus desirable volunteers) relative to
adjacent (off -ROW) vegetation atter the first complete growing season. Additional
seeding will be completed during the next seeding season (fall or spring). In the event
that first year revegetation is affected by precipitation amounts significantly below the
annual average, the Company may request deferment of additional seeding activities until
the following seeding window.
The reclaimed ROW will be considered stable when the surface appears similar to
adjacent undisturbed land and the following accelerated erosion indicators do not exist:
♦ perceptible soil movement (exceeding pre -construction conditions)
♦ head cutting in drainages
+ flow pattern development resulting in large (greater than 12 inches in depth) rills or
gullies
♦ trench subsidence or slumping
Revegetation will be considered successful when the following criteria are met
♦ total herbaceous (seeded species plus desirable volunteers) cover is at least 75
percent of that on adjacent land,
• species composition comprised of a mix of seeded species and desirable volunteers
from adjacent communities, and

1. INTRODUCTION
The Fire Prevention and Suppression Plan (plan) identifies measures to be taken by EnCana
Gathering Services (U.S.A.) Inc. (Company) and its contractors (Contractor) to ensure that fire
prevention and suppression techniques are carried out in accordance with federal, state, and local
regulations. Measures identified in this plan apply to work within the project area defined as the
right-of-way (ROW), access roads, all work and storage areas, and other areas used during
construction of the project.
2. PURPOSE
The risk of fire danger during pipeline construction is related to smoking, refueling activities,
operating vehicles and other equipment off roadways, welding activities and the use of
flammable liquids. During pipeline operation, risk of fire is primarily from unauthorized entry
onto the ROW. During maintenance operations, risk of fire is from vehicles and pipeline
maintenance activities that require welding.
This plan establishes standards and practices that will minimize the risk of fire danger and, in
case of fire, provide for immediate suppression.
3. RESPONSIEILITIES AND COORDINATION
This plan will be implemented by the Company and the Contractor on the project. The Company
and the Contractor have the responsibility for providing all necessary fire -fighting equipment on
the project site to their respective employees, and operating under the requirements of this plan.
Prior to construction, the Company will contact the appropriate authorities to establish
communications, obtain permits (if applicable), and/or fulfill other obligations as directed by fire
control authorities. In addition to the above, the Company will:
• Ensure that prevention, detection, pre -suppression, and suppression activities are in
accordance with this fire plan and federal, state and county laws, ordinances, and
regulations pertaining to fire.
• Accompany agency representatives on fire tool and equipment inspections and take
corrective action upon notification of any fire protection requirements that are not in
compliance; and
The fire prevention and suppression measures described in this plan will be in effect from June 1
to the end of construction. These dates may change by advance written notice by fire control
authorities. However, required tools and equipment will be kept in serviceable condition and be
immediately available for fire suppression at all times.
4. FIRE PREVENTION MEASURES
4.1 PRECONSTRUCTION AND CONSTRUCTION
Methods and procedures that will be implemented prior to and during the construction
period to minimize the risk of fire are described below.
4.1.1 Training
Contractor will train all personnel about the measures to take in the event of a fire.
Contractor will also inform each construction crewmember of fire dangers,
locations of extinguishers and equipment, and individual responsibilities for fire
prevention and suppression during regular safety briefings. Smoking and fire
rules will also be discussed with the Contractor and all field personnel during the
project's environmental training program.
4.1.2 Smoking
Smoking is prohibited except in areas cleared and graded a minimum of 10 feet in
diameter to mineral soil. All burning tobacco and matches will be extinguished
before discarding. Smoking is also prohibited while operating equipment or
vehicles, except in enclosed cabs or vehicles.
4.1.3 Spark Arresters
During construction, operation, maintenance, and termination of the ROW, all
Contractor and Company equipment operating with an internal combustion engine
will be equipped with federally approved spark arresters. Spark arresters are not
required on trucks, buses and passenger vehicles (excluding motorcycles) that are
equipped with an unaltered muffler or on diesel engines equipped with a
turbocharger. A BLM fire prevention officer will have full authority to inspect
spark arresters on project equipment prior to its use on the project on federal lands
and periodically during the constriction project.
4.1.4 Parking, Vehicle Operation and Storage Areas
In no case will motorized equipment, including worker transportation vehicles be
driven or parked outside of the designated and approved work limits. Equipment
parking areas, the ROW, staging areas, designated vehicle -parking areas, and
small stationary engine sites, where permitted, will be cleared of all flammable
material. Clearing will extend a minimum of 10 feet beyond the edge of the area
to be occupied, but not beyond the boundaries of the approved ROW, extra
workspace, or ancillary site. Glass containers will not be used to store gasoline or
other flammables.
4.1.5 Equipment
All motor vehicles and equipment will carry one long -handled (48 -inch
minimum), round -point shovel, and one dry chemical fire extinguisher (5 pounds
minimum). Individuals using power saws and grinders will have a shovel as
described above, and an 8 -ounce capacity fire extinguisher immediately available.
The Fire Guard will operate a truck equipped with a 125 gallon slip-on pump unit
designed for wildland firefighting. All equipment will be kept in a serviceable
condition and readily available.
4.1.6 Road Closures
Contractor will notify the appropriate fire suppression agency of the scheduled
closures prior to the open -cut crossing of a road. If required, Contractor will
construct a bypass prior to the open -cut installation of a road crossing, unless a
convenient detour can be established on existing project approved roads or within
project approved work limits. All bypasses will be clearly marked by the
Contractor. During road closures the Contractor will designate one person, who
knows the bypass, to direct traffic. Contractor will minimize, to the extent
possible, the duration of road closures.
4.1.7 Refueling
Fuel tracks will have a large fire extinguisher charged with the appropriate
chemical to control electrical and gas fires. The extinguisher will be a minimum
size 35 -pound capacity with B.C. or higher rating.
4.1.8 Burning
No burning of slash, brush, stumps, trash, or other project debris will be permitted
on the project.
4.1.9 Fire Guard
Contractor will designate a Fire Guard for the construction spread prior to
construction activities. The Fire Guard must be physically able, vigilant, and
suitably trained to detect fires and use required fire -fighting equipment. The Fire
Guard may not perform other functions during pipeline construction in addition to
his/her Fire Guard responsibilities. The Fire Guard will be identified by a hard-
hat decal and/or other appropriate designation. An alternate or back-up Fire
Guard will be designated to assume responsibility, if the primary guard is unable
to perform their duties. Contractor will provide, if required by the Company,
additional fire watch -people with radio communication to the Fire Guard should
construction activities be too widely spread for one Fire Guard to manage
effectively.
4.1.9.1 Fire Guard Communications: The Fire Guard will be responsible
for maintaining contact with fire control agencies, and will be equipped
with a radio or cellular telephone so immediate contact with local fire
control agencies can be made. If cellular phone coverage is not available,
the Fire guard will use the Contractor's frequency to contact their radio
base at the Contractor's yard. From there, yard personnel will telephone
emergency dispatch.
4.1.10 Welding
One 5 -gallon backpack pump will be required with each welding unit in addition
to the standard fire equipment required in all vehicles. All equipment will be kept
in a serviceable condition and readily available.
4.1.11 Restricted Operations
The Contractor will restrict or cease operation on federal lands during periods of
high fire danger at the direction of the responsible BLM or USFS Fire
Management Officer. The Contractor will restrict or cease operations during
periods of high fire danger at the direction of the Mesa County Sheriff's Office
Fire Marshal. Restrictions may vary from stopping certain operations at a given
time to stopping all operations. The Company may obtain approval to continue
some or all operations if acceptable precautions are implemented
4.1.12 Monitoring
Construction and Environmental Inspectors for the Company will inspect the job
site and the Contractor's operations for compliance with all provisions of this
plan. In addition, federal, state, and local fire control agencies may perform
inspections in areas under their jurisdiction at their discretion.
4.2 PIPELINE OPERATION
During pipeline operation, the risk of fire danger is minimal. The primary causes of fire
on the ROW result from unauthorized entry by individuals utilizing the ROW for
recreational purposes and from fires started outside of the ROW. In the latter case, the
ROW can be used by authorities as a potential fire break. During pipeline operation,
access to the ROW will be restricted, in accordance with landowner requirements, to
minimize recreational use of the ROW.
4.3 PIPELINE MAINTENANCE
During maintenance operations, The Company or its Contractor will equip personnel with
basic fire -fighting equipment including fire extinguishers, and shovels as described in
Section 4.1.5 Equipment. Maintenance crews will also carry emergency response/fire
control contact phone numbers.
5. FIRE SUPPRESSION
5.1 SUPPRESSION
Contractor will take the following actions should a fire occur within the project area
during construction.
• Take immediate action to suppress fires using all available manpower and equipment.
Notify the Fire Guard.
• Immediately notify the nearest fire suppression agency of the fire location, action
taken, and status (refer to Fire Suppression Contacts for a list of fire suppression
agencies and emergency phone numbers).
• Immediately notify the Company of the fire location and action taken.
• Relinquish the Fire Guard's direction of fire suppression activities to agency fire
management officers upon their arrival.
If a reported fire is controlled, the Fire Guard will note the Location and monitor the
progress in extinguishing the fire. The Fire Guard or their designee will remain at the fire
scene until it is fully extinguished. The extinguished fire will be monitored in accordance
with procedures described in Section 5.2 below.

1. INTRODUCTION
This Hazardous Materials Management and Spill Prevention and Countermeasure Plan
(HAZMAT Plan) describes measures to be taken by the EnCana Gathering Services (U.S.A.)
Inc. (Company) and its contractors (Contractor) to reduce the risks associated with the use,
storage, transportation, production, and disposal of hazardous materials (including hazardous
substances and wastes) and petroleum products. In addition, this plan outlines the required spill
prevention and response (cleanup) procedures for the project.
The HAZMAT Plan prepared as part of the Stormwater Pollution Prevention Plan as required by
the project's National Pollution Discharge Elimination System (NPDES) permit for stormwater
discharges. This plan was prepared in accordance with good engineering practices.
In general, hazardous materials and clean-up equipment will be stored at the construction yard.
Material Safety Data Sheets (MSDS) will be maintained at the Contractor's yard(s) throughout
the construction period.
The Contractor will prepare and have the Company review and approve a HAZMAT Plan prior
to any storage of hazardous substances or petroleum products. The Company will have 10 days
to review submitted plans.
1.1 PURPOSE OF PLAN
The purpose of this plan is to provide a description of hazardous materials management,
spill prevention, and spill response/cleanup measures associated with the construction,
operation, and maintenance of the project. In addition this plan provides Contractors
with requirements and guidance for the creation of their own HAZMAT Plan.
1.2 OVERVIEW OF THE PLAN'S COMPONENTS
This plan includes the following components: (1) an introduction; (2) a description of the
spill prevention procedures related to vehicle refueling and servicing and the
transportation, storage, and disposal of hazardous materials; (3) guidelines for developing
the Contractor's HAZMAT Plan; (4) a description of the physical and procedural methods
for spill control and cleanup; and (5) an overview of the notification and documentation
procedures to be followed in the event of a spill.

This plan is intended to comply with and compliment existing regulations pertaining to
the safe use of hazardous materials. Persons responsible for handling hazardous
materials for this project will be trained in the proper use/management of the materials
and will be familiar with all applicable laws, policies, procedures, and best management
practices (BMP's) related to them.
2. CONTRACTOR'S GUIDELINES FOR DEVELOPING THE HAZMAT PLAN
The following sections provide specific guidelines for the preparation of the HAZMAT Plan by
Contractor.
2.1 CERTIFICATIONS, ACKNOWLEDGMENTS AND DESIGNATION OF
COORDINATOR RESPONSIBLE PERSON(S)
2.1.1 Certifications
Contractor will certify that all of the information provided in the HAZMAT Plan
is accurate and complete to the best of their knowledge. Contractor will also
certify that they are committed to implementing the HAZMAT Plan as written.
As per the requirements of 40 CFR, Part 112, Contractor will have the HAZMAT
PLAN reviewed and certified by a registered Professional Engineer.
2.1.2 Amendments
•
In completing this certification, Contractor will agree to make all necessary and
appropriate amendments to the plan and submit any such amendment to the
Company and the appropriate county, state, and/or federal authorities within 7
days of finding an amendment is necessary. Amendments to the plan will be

• any handling of a previously undisclosed hazardous material subject to
inventory requirements
• a change of business address, name, or ownership.
2.1.3 Responsible Person(s)
Contractor is responsible for contacting county representatives to determine
county requirements for Hazardous Materials Business/Management Plans.
Generally counties will provide guidelines and forms for completion and
submittal to the county. As required on the applicable county forms that the
Contractor will obtain, Contractor will designate a primary emergency
coordinator for hazardous materials management and emergency response. Two
alternates will also be identified. Business, residential, and cellular or pager
telephone numbers will be provided for all three persons as necessary, to allow for
contact on a 24-hour basis. Primary and alternate emergency coordinators will be
knowledgeable of the chemicals and processes involved in Contractor's operation.
They will have full access to all facilities, including locked areas, and must have
the authority to commit company resources. They will also have stop work
authority to prevent impacts (potential or actual) to environmental resources.
2.2 FACILI I7ES' DESCRIPTION AND INVENTORY OF MATERIALS
Contractor's submittals will be provided to the Environmental Inspector. The
Environmental Inspector will provide submitted information to the jurisdictional agencies
as appropriate.
2.2.1 Site Map
Contractor will complete the relevant county forms related to business
information and description. The Contractor is also required to provide a site
map/facility map for each construction yard indicating storage and safety
precautions for hazardous materials and hazardous wastes. The Contractor's site
map will, at a minimum, indicate the following:
♦ orientation and scale
♦ total land area in square feet
♦ access and egress points
♦ buildings and/or temporary trailers
• parking lots
• adjacent land uses (if business, indicate business name)
♦ surrounding roads, storm drains, and waterways (including waterbodies and
wetlands)
• . locations of hazardous materials and hazardous waste storage
• underground and above ground tanks
• containment or diversion structures (dikes, berms, retention ponds)
• shutoff valves and/or circuit breakers
♦ location of emergency response materials and equipment
• location of MSDS and HAZMAT PLAN
i) ♦ location of emergency assembly area
♦ location of clean up equipment within the yard
As noted in Section 3.6 - Storage of Hazardous Materials, hszardous materials
will be stored only in designated staging areas 100 feet from streams (dry and
wet) and wetlands (dry and wet) and equipment storage yards. Temporary pumps,
diesel powered generators, etc., will be located at least 100 feet from the edge of
streams (dry and wet), wetlands (including dry or seasonal wetlands), and other
sensitive areas defined by the project's Environmental Inspectors. If storage areas
cannot be. located at least 100 feet from streams and wetlands because of
topographic conditions or space, the Contractor will also provide a sketch of
where the materials will be stored in relation to the waterbody and location of
clean up equipment. Include measures to be implemented for secondary
containment as specified in Section 3.6.1, Physical Storage Requirements.
2.2.2 Inventory
Contractor will provide a complete inventory to the Company of all hazardous
substances that will be used (refer to Title 40, CFR, Parts 116 and 302). All
inventory forms required by the relevant county will be provided by the
Contractor as part of their HAZMAT Plan.
3. HAZARDOUS MATERIALS MANAGEMENT
Construction, operation, and maintenance of the project will require the use of certain potentially
hazardous materials such as fuels, and herbicides. By definition, hazardous materials
(substances and wastes) have the potential to pose a significant threat to human health and the
environment based upon their quantity, concentration, or chemical composition. Generally,
hazardous materials will be stored in the Contractor's yard and not on the right-of-way (ROW).
When stored, used, transported, and disposed of properly as described below, the risks associated
with these materials can be reduced substantially.
3.1 OVERVIEW OF HAZARDOUS MATERIALS PROPOSED FOR USE
The following project -specific measures pertain to all vehicle refueling and servicing
activities as well as the storage, transportation, production, and disposal of hazardous
materials (substances/wastes). These measures are intended to prevent the discharge of
fuels, oils, gasoline, and other harmful substances to waterbodies, groundwater aquifers,
and/or other sensitive resource areas during project construction.
Hazardous materials (substances) used during project construction may include solvents,
and other substances. In addition petroleum products such as gasoline, diesel fuel,
Lubricating oils, and hydraulic fluid will be used. Some of these materials will be used in
relatively large quantities at staging areas, in storage yards, and on the ROW to operate
and maintain equipment during construction. Smaller quantities of other materials such
as: herbicides, paints, and other chemicals will be used during project operation and
maintenance. These materials will be used to control noxious weeds and facilitate
revegetation on the ROW, and to operate and maintain meter stations during the life of
the project.
Additional materials will be necessary at other locations along the ROW (e.g., river
crossings, hydrostatic test stations) and at off -ROW construction yards. Listings of other
hazardous materials that will be used during construction, operation, and maintenance of
the project in other locations will be identified on the Contractor's Hazardous Substances
Inventory form included in Attachment 1. The Company will compile all Contractor's
submittals and update Attachment 1 prior to start of construction. The Company will
update the inventory of hazardous materials used/stored on the project as needed
throughout the life of the project. This information will be provided to the appropriate
regulatory agencies as required (i.e., the BLM requires reporting of all hazardous
materials as defined by CERCLA, RCRA, and the Environmental Protection Agency
(EPA). A copy of the compiled Attachment I will be provided to the BLM.).
3.2 TRAINING
All project personnel will be required to receive basic spill prevention training. The
Company is required to maintain a record of those workers who have received
environmental training and ensure that only trained employees are allowed to work on the
project. In addition all Contractor personnel who will be involved with the transportation
and storage of fuels or hazardous substances, equipment maintenance, and spill response
will be required to attend a higher level training class given by the Contractor as
described in Section 5.2.
3.3 VEHICLE REFUELING AND SERVICING
Construction vehicles (e.g., trucks, bulldozers, etc.) and equipment (e.g., pumps,
generators, etc.) will be fueled/serviced in designated upland staging areas at least 100
feet front waterbodies and wetlands (including dry streams and dry or seasonal wetlands,
refer to the stream and wetland crossing list in the Stream Crossing and Wetland
Protection Plan). If pumps, generators, etc. cannot be located at least 100 feet from
streams and wetlands because oftopographic conditions or space limitations, special
precautions (e.g. placing pumps and small refueling cans in secondary containment
structures) will be taken to prevent the spill or release of hazardous materials into the
waterway. Fueling will not occur within 200 feet of private wells or 400 feet of
municipal wells. When selecting refueling areas, consideration will be given to slopes
and other topographic conditions. Refueling locations will generally be flat to minimize
the chance of spilled substance reaching a waterbody. In most cases, rubber -tired
vehicles will be refueled and serviced at local gas stations or equipment yards off the
ROW. Tracked vehicles will typically be refueled and serviced by fuel/service vehicles
on the ROW. Every effort will be made to minimize the threat of a fuel spill during
refueling and servicing. Fuel/service vehicles will carry extra plastic, a bucket or plastic
pan to catch fuel, and a minimum of 20 pounds of suitable absorbent material to handle
potential spills. In addition, all vehicles will be inspected for leaks prior to being brought
on-site and regularly throughout the construction period. In the event that a leak(s) is
found, equipment will not be allowed to operate until all leaks have been repaired.
Vehicles will also be equipped with fire fighting equipment as specified in the Fire
Prevention and Suppression Plan.
Construction equipment requiring maintenance which might result in the draining or
leaking of fluids will be serviced only after a 12 mil plastic liner has been installed
between the equipment and the soil. This liner must be placed in such a manner that all
fluid is contained.
Washing of construction vehicles (such as concrete trucks) will be allowed only in
construction staging areas at least 100 feet from waterbodies and wetlands (including dry
streams and dry or seasonal wetlands). Washing areas will be contained with berms or
barriers to prevent migration of wastewater and/or sediments into waterbodies. Waste
concrete material will be removed and properly disposed of once it has hardened. _
3.4 EQUIPMENT INSPECTION AND DECONTAMINATION
Prior to moving equipmentonto the ROW, the Environmental Inspector will check
equipment for leaks while also inspecting the equipment for weeds. All equipment will
be cleaned and weed -free prior to being moved to the ROW. Equipment contaminated
from fuel or hydraulic line breaks will be cleaned with diapers and the diapers will be
disposed of properly.
3,5 TRANSPORTATION OF HAZARDOUS MATERIALS
Procedures for loading and transporting fuels and other hazardous materials will meet the
minimum requirements established by the Department of Transportation (DOT) and other
pertinent requirements. At all times, hazardous materials will be transported in DOT
approved containers. Prior to transporting hazardous materials, appropriate shipping
papers will be completed. Vehicles carrying hazardous materials will be equipped with
shovels, barrier tape, 4 to 6 mil plastic bags, personal protective clothing, and spill pads
to contain a small spill should oneoccur during transport. In addition, vehicles
transporting such materials will be properly signed (placarded) and/or marked. Prior to
transporting hazardous materials, vehicles will be inspected for leakage and other
potential safety problems. The Contractor will ensure that vehicle drivers are properly
trained to respond to and report spills, leakage, and/or accidents involving hazardous
materials (see Section 5.2 of this plan).
All hazardous materials used for the project will be properly containerized and labeled at
all times, including during transportation. Smaller DOT approved containers will be used
on-site to transport needed amounts of hazardous materials to a specific location.
Transfer of materials from large to small containers will not be done by hand pouring, but
will be accomplished using appropriate equipment including pumps, hoses, and safety
equipment. These smaller ("service") containers will also be clearly labeled.
3.6 STORAGE OF HAZARDOUS MATERIALS
Hazardous materials will be stored only in designated staging areas 100 feet from streams
(dry and wet) and wetlands (dry and wet) and equipment storage yards. Temporary
pumps, diesel powered generators, etc., will be located at least 100 feet from the edge of
streams (dry and wet), wetlands (including dry or seasonal wetlands), and other sensitive
areas defined by the project's Environmental Inspectors. If storage areas cannot be
located at least 100 feet from streams and wetlands because of topographic conditions or
space limitations, special precautions will be taken to prevent the spill or release of
hazardous materials into the waterway. These precautions will include limiting the
quantity and amount of time such materials are stored near the stream or wetland,
providing secondary containment, and using trained personnel to monitor activities at the
storage site. Storage of greater than 55 gallons of hazardous materials will not be
permitted within 100 feet of streams or wetlands. Cleanup materials, including absorbent
spill pads and plastic bags, will also be stored in these areas. Hazardous materials will
not be stored in areas subject to flooding or inundation.
3.6.1 Physical Storage Requirements
Security: Hazardous materials will be stored in secure areas to prevent damage,
vandalism, or theft. During construction hours, hazardous materials may be
stored temporarily on the ROW but overnight storage on the ROW will be
prohibited. All storage containers will remain sealed when not in use and storage
areas will be secured (gated, locked, and/or guarded) at night and/or during non-
construction periods.
Storage Containers: Containers will be compatible with the hazardous materials
or wastes stored. If the container leaks or becomes damaged, the substance must
be transferred to a container in good condition. Contractor will inspect containers
at least weekly to discover any leaks in the containers or the containment systems.
Containers used for transportation must comply with the DOT requirements,
including those in Title 49, CFR, Part 173.
Secondary Containment: Secondary containment will consist bermed or diked
areas that are lined and capable of holding 110 percent of the volume of the stored
material plus any potential precipitation accumulation, and will be provided for
fuel and oil tanks stored on- site [e.g., in Contractor's yard(s)].
Container Management: Containers holding hazardous substances will be kept
closed during transfer and storage, except when it is necessary to add or remove
the substance.
Incompatible Wastes: Wastes that are incompatible with other wastes will not be
placed in the same container, nor in an unwashed container, that previously held
an incompatible material.
Ignitable or Reactive Substances: Substances that may ignite or are reactive must
be located at least 50 feet from the construction yard boundary. "NO SMOKING"
signs will be conspicuously placed wherever there is a hazard from ignitable or
reactive waste. Examples of ignitable wastes are: paint wastes, certain degreasers,
thinners and solvents (petroleum distillates), epoxy resins, and adhesives.•
Examples of a reactive wastes that may be found at construction yards includes
permanganate and manganese wastes from dry cell batteries.
Storm Water: It may be necessary to drain accumulated storm water from within
the secondary containment areas that contain the fuel storage tanks. If the storm
water has been contaminated, absorbent pads or booms will be used to remove
floating petroleum products. After the contamination has been removed, the
storm water will be left to evaporate, if possible, otherwise it will be disposed of
in an appropriate manner. Prior to disposal, the Environmental Inspector will
check for sheen or other evidence of contamination.
3.6.2 Container Labeling Requirements for Hazardous Wastes
Contractor will comply with the following labeling requirements for any on-site
container (including tanks) used to store accumulated hazardous wastes. The
containers will be labeled as required in Title 40 CFR, Part 262 and will contain at
least the following information:
• chemical name (oil, diesel, etc.),
• the accumulation start date and/or the date the 90 -day storage period began;
and
i •
♦ the words "Hazardous Waste" and warning words indicating the particular
hazards of the waste, such as "flammable","corrosive", or "reactive."
3.7 DISPOSAL OF HAZARDOUS WASTES
Contractor will be responsible for ensuring that all hazardous wastes generated during
their operations are collected regularly and disposed of in accordance with all applicable
laws. Contractor will determine details on the proper handling and disposal of hazardous
waste, and will assign responsibility to specific individuals prior to construction of the
project.
Hazardous wastes typically include chemicals, spent batteries, and other items.
Contractor will ensurethat every effort will be made to minimize the production of
hazardous waste during the project including, but not limited to, minimizing the amount
of hazardous materials needed for the project; using alternative non -hazardous substances
when available; recycling usable materialssuch as paints and batteries to the maximum
extent; and filtering and reusing solvents and thinners whenever possible.
Any Contractor (generator) producing more that 100 kilograms per month of hazardous
waste must apply for an EPA Identification Number. Contractor (generator) producing
less than 100 kg per month are considered conditionally exempt small quantity
generators. A generator can store hazardous wastes on-site for a period of up to 90 days
without having to obtain a permit as a storage facility, or as a small quantity generator up
to a total of 1000 kilograms.
3.8 CONTAMINAthD CONTAINERS
Containers that once held hazardous materials as products or which held hazardous
wastes must be considered as potential hazardous wastes due to the residues of hazardous
contents that may persist. In order for the container to be handled as non -hazardous
waste, regulations require that the container be essentially empty and that certain
handling requirements for the empty container be followed, including the following:
♦ The containers must be empty, which means as much of the contents as possible have
been removed so that none will pour out in any orientation and that they contain less
than 1 pound and require special handling because of the waste type.
• If the empty containers are less than five gallons, they may be disposed of as a non-
hazardous solid waste or scrapped.
• If the empty containers are greater than five gallons, they must be handled in the
following manner:
o returned to the vendor for re -use,
o sent to a drum recycler for reconditioning, or - used or recycled on-site.
3.9 WASTE OIL FILTERS
Used, metal canister oil filters can be managed as solid waste as long as they are
thoroughly drained of "free flowing" oil (oil .exiting drop -by -drop is not considered "free
flowing"); the filters are accumulated, stored, and transferred in a closed, rainproof
container. Waste oil filters are best drained by puncturing and gravity draining while the
filter is still hot.
3.10 USED LUBRICATING OIL
Waste lubrication oil, including contaminated soil and rags, have specific requirements
for storage, transportation, and disposal. Contractors are considered "Used Oil
Generators" and as such must meet the following requirements:
• Have a HAZMAT Plan certified by a registered Professional Engineer and approved
by the Company.
♦ Conduct spill prevention briefings frequently enough to assure adequate
understanding by all workers.
• Label all storage containers "Used Oil".
• Ensure storage containers do not have visible leaks and have secondary containment
equal to 110 percent, plus potential precipitation.
♦ Designate an individual who is accountable for managing oil spills.
• Hire a subcontractor with an EPA identification number for the transportation of used
oil, or limit transported quantities to 55 gallons.
• Dispose of used oil in a manner consistent with state and federal regulations
♦ Provide documentation if required.
3.11 INSPECTION AND RECORD KEEPING
Contractor will inspect all storage facilities on a regular basis, but not less than weekly.
The Weekly Hazardous Materials/Wastes Inspection Log in Attachment 2, will be used to
record the condition of the facility. In addition to the weekly log, Contractor will
maintain records for hazardous materials and hazardous wastes as required by all
applicable federal, state, and local regulations and permit conditions. Record keeping
requirements include:
• hazardous material/waste inspection log
• transportation documents
• bills of lading
• manifests
• shipping papers
• training records
• release report forms
♦ spill history
Environmental Inspectors will monitor, inspect, document, and report on Contractor's
compliance with all hazardous materials and hazardous waste management practices.
4. POTENTIALLY CONTAMINATED STYES
This general procedure is included as a contingency in the event that unexpected or unknown
(pre-existing) contaminated sites are encountered during the course of construction. During the
course of construction, some potential exists for encountering contaminated soils, groundwater,
or other materials. Should such a situation develop where there is a reasonable basis for
believing that contaminated materials have been encountered (where contamination is suggested
by visible indications or unusual odors), the Contractor will stop work and immediately notify
the Environmental Inspector or the Construction Supervisor. The Environmental Inspector or
Construction Supervisor will determine next steps, including notification requirements. The
Contractor may not commence work without authorization.
5. SPILL CONTROL AND COUNTERMEASURES
The measures described in Section 3.0 of this plan are intended to prevent the spill of hazardous
materials during normal project construction, operation, and maintenance activities. However,
not all potential spill situations can be reasonably foreseen or prevented. In accordance with
Section 6.1 - Reporting Criteria, the Environmental Inspector will make a note of minor spills
and cleanup in their daily logs. These minor spills will be documented in the daily report taken
in the event of a major spill. In general, the Contractor will perform all cleanup activities
including: (1) specifying in their HAZMAT PLAN specific containment and cleanup
procedures; (2) providing necessary materials and labor, and (3) performing all reporting and
documentation, as required. Notification and documentation of spills is discussed in greater
detail in Section 6.0 of this plan.
5.1 PHYSICAL AND PROCEDURAL RESPONSE MEASURES
Physical response actions are intended to ensure that all spills are promptly and
thoroughly cleaned up. However, the first priority in responding to any spill is personnel
and public safety. • Construction personnel will be notified of evacuation procedures,
including evacuation routes, to be used in event of a spill emergency. In general, the first
person on the scene will:
• attempt to identify the source, composition, and hazard of the spill or stain;
• isolate and stop the spill and begin clean up of the spill or stain, if possible (i.e., if it
is safe).
• contain spills or stains, of unknown substances, in a barrel or plastic to prevent
migration if rain occurs,
• properly store, and
• obtain a sample of the unknown substance for laboratory analysis
i
•
• notify appropriate personnel and initiate reporting actions; and
• initiate evacuation of the area if necessary.
Persons should only attempt to clean up or control a spill if they have received proper
training. Untrained individuals will immediately notify the Contractor's primary or
alternate emergency coordinators.
If there is a spill of an unknown substance and its identity cannot be determined by
observing obvious clues (i.e. labels on containers, or observing an obvious sources (e.g,,
Hydraulic lines, fuel tanks, etc.), it would not be considered safe for the average person to
contain the spill and obtain sample for laboratory analysis. Any spill of an unknown
substance should be treated as a hazard and should be approached, contained and sampled
by trained emergency response personnel. General construction personnel should be
instructed to contain and cleanup spills of only those substances they can safely identify
and that can be safely approached (from upwind an upgradient) and handled, after
identifying the materials from a safe distance and location.
In general, expert advice will be sought to properly clean up major spills (defined as any
spill over the reportable quantity for that substance). For spills on land, berms will be
constructed to contain the spilled material and prevent migration of hazardous materials
or petroleum products toward waterways. Dry materials will not be cleaned up with
water or buried. Contaminated soils will be collected using appropriate machinery,
stored in suitable containers, and properly disposed of in appropriately designated areas
off-site. After contaminated soil is recovered, all machinery utilized will be
decontaminated, and recovered soil will be treated as used oil if contaminated with
petroleum products or hazardous waste if contaminated with hazardous waste.
Contaminated cleanup materials (absorbent pads, etc.) and vegetation will be disposed of
in a similar manner. For major spills, cleanup will be verified by sampling and
laboratory analysis.
If spilled materials reach water, booms and skimmers will be used to contain and remove
contaminants. Other actions will be taken as necessary to cleanup contaminated waters.
In areas where construction activity will cross a small flowing waterbody (25 feet or
less), absorbent booms will be placed on the water surface downstream of the
construction zone, prior to construction. Clean-up materials including absorbent spill
pads and plastic bags will be placed on site at flowing streams and "wet" wetlands when
construction is occurring within 100 feet of these areas. For river crossings over 25 feet,
cleanup materials will be located on both banks.
5.1.1 On -Site Equipment
The following equipment will be maintained on site with each crew using heavy
equipment for use in cleanup situations.
♦ Shovels
• absorbent pads/materials
• personal protective gear
• fire fighting equipment
♦ medical first-aid supplies
• phone list with emergency contact numbers
• storage containers
• communications equipment
5.2 EMPLOYEE SPILL PREVENTION/RESPONSE TRAINING AND
EDUCATION
Contractor will provide spill prevention and response training to appropriate construction
and inspection personnel. Persons accountable for carrying out the procedures specified
herein will be designated prior to construction and informed of their specific duties and
responsibilities with respect to environmental compliance and hazardous materials.
Contractor is required to maintain a record of those workers who have received training.
Note that this training is in addition to the environmental training that will be conducted
by the Company. Contractor's training will be provided to inform appropriate personnel
of site-specific environmental compliance procedures. At a minimum, this training will
include the following:
• a review of the Company and Contractor HAZMAT Plan, and discussion of
individual responsibilities;
• an overview of allregulatory requirements;
• methods for the safe handling/storage of hazardous materials and petroleum
products;
• spill prevention procedures;
• operation and location of spill control materials;
• inspection procedures for spill containment equipment and materials;
• emergency response procedures;
• use of personal protective equipment (PPE);
• use of spill cleanup equipment;
• procedures for coordinating with emergency response teams;
• standard information regarding a spill to be provided to Company for agency
notification (see Section 6.1);
6. NO 1'1NICATION AND DOCUMENTATION OF SPILL PROCEDURES
Notification and documentation procedures for all spills that occur duringproject construction,
operation, or maintenance will conform to applicable federal, state, and local laws. Adherence to
such procedures will be the top priority once initial safety and spill response actions have been
taken. The following sections describe the notification and documentation procedures, and
should be implemented in conjunction with the response procedures listed in other sections of
this plan.
6.1 REQUIRED NOTIFICATION
Notification will begin as soon as possible after discovery of a release. The individual
who discovers the spill will contact a Company Construction or Environmental Inspector.
If the Environmental Inspector determines that the spill meets the criteria for immediate
verbal notification of government agencies (see Section 6.1.3, Reporting Criteria) and/or
determines that the spill may threaten human health or the environment, he/she will
immediately notify Company's Field Supervisor who will make the required agency
notifications as described below. On federal lands, all spills greater than 1 gallon will be
reported. Prior to beginning the notification process, the individual initiating notification
should obtain as much information as possible to clearly document and communicate the
situation. See Section 6.1.1 for standard information that will be requested by agencies.
The project is not expected to impact the Colorado River. However, the pipeline will
cross beneath the river. Directional boring techniques will be utilized to install the
pipeline. The borehole will be drilled at an approximate depth of 20 feet below the
lowest point of the river bed.
The following mandatory notifications will be made by the Environmental Inspector.
♦ 911 will be called if the spill is deemed to be an emergency
♦ BLM, Glenwood Springs Field Office -(970) 947-2800
♦ BLM, Grand Junction Fire Dispatch -(970) 257-4800
♦ National Response Center (800) 424-8802 (for amounts exceeding the reportable
quantity for that material (see section 6.1.3, Reporting Criteria)
♦ Colorado Department of Health and Environment -(303) 692-3500 non -emergency
(303) 756-4455 emergency
♦ Grand Junction State Patrol/State Hazardous Materials Team, for spills occurring
on State Highway rights -of —way- (970) 248-7278
♦ Local Emergency Planning Committee -notified at the following numbers.
Garfield County (Glenwood Springs, CO) (970) 945-9151
♦ If the spill or leak has the potential to affect BLM lands, the State Patrol and
BLM must be notified immediately (with respect to the State Patrol, this
requirement applies only for spills occurring on State Highway rights-of-way).
s If the spill or leak has the potential to affect USFS lands, the State Patrol and
USFS must be notified immediately (with respect to the State Patrol, this
requirement applies only for spills occurring on State Highway rights-of-way.
6.1.1 Agency Notification
When notifying a regulatory agency, the Environmental Inspector will provide the
following information:
• current threats to human health and safety, including known injuries, if
any; spill location (legal land description if available), including
landmarks and nearest access route; reporter's name and phone number,
time the spill occurred;
• type and estimated amount of hazardous materials involved;
• potential threat to property and environmental resources, especially
waterbodies and wetlands; and
♦ status of response actions.
On-site personnel should always consult the Environmental Inspector to clarify
regulatory requirements.
6.1.2 Landowner Notification
When a spill poses a direct and immediate threat to health and safety and/or
property, the landowners potentially affected by the spill will be directly notified
by the Company. The Alignment Sheets delineate land ownership along the
entire ROW and will be used to determine affected landowners. Immediate
notification of landowners is required for all situations in which the spill poses a
direct and immediate threat to health and safety and/or property.
6.1.3 Reporting Criteria
The Contractor will report to the Company Environmental Inspector all hazardous
substance releases regardless of size and petroleum product spills which threaten
or enter any waterbody, or that are over 1 quart in size. Verbal reports are
required immediately following a major spill when doing so would not delay
clean up or administration of urgent medical care. The Company Environmental
Inspector will determine if the spill meets the following criteria for immediate
agency notification. Any release of hazardous material over the applicable
reportable quantities (List of Reportable Quantities), or a petroleum product spill
which threatens or enters a waterbody must be reported immediately to the
National Response Center (NRC), the BLM, state, and local authorities. On
federal lands, all spills greater than 1 gallon will be reported. For petroleum spills
over 25 gallons which occur in upland areas notification will be made to the
BLM, state, and local authorities.

6.2 DOCUMENTATION
Contractors will maintain records for all spills. Agencies that the Company verbally
notified of a release will be given written notification by the Company within 30 days.
Contractor will provide a written report of all reportable spills requiring agency
notification within 24 hours (see Attachment 1).
The Contractor will record spill information in a daily log. The following is a list of items
that should be included in the daily log (as appropriate, based on the spill incident):
• time and date of each log entry;
• name of individual recording log entry;
• list of all individuals notified, including time and date;
♦ type and amount of material spilled;
♦ resources affected by spill;
+ list of response actions taken, including relative success;
+ copies of letters, permits, or other communications received from government
agencies throughout the duration of the spill response;
♦ copies of all outgoing correspondence related to the spill; and
• photographs of the response effort (and surrounding baseline photographs if relevant).
Maintaining detailed and organized records during a spill incident is an important and
prudent task. One Contractor representative should be designated to manage the records
for an incident. If extensive spill redponse and cleanup operations are required, the
Contractor may choose to assign a bookkeeper to assist in the documentation process.
The Contractor's on-site bookkeeper will track and manage all expenditures (i.e.,
equipment, personnel/labor hours, and associated resources) and will help supplement the
information provided in the daily log book
