WIRE CAITLE FENCES
For three-strand wire fences, the CDOW recommends that the top wire be
a 12 Y. gauge twisted, baJbless type at a maximum height of 42" It is
critical that the middle wire, wbich can be barbed, be located a minimum
of 12" below the top wire for kick space, to prevent entanglement when
elk and deer jump over it Keep top wire tight-a loose top wire can canse
an elk or deer's leg to become twisted with the next wire. Tho bottom
wire should be 16" above the ground
Clreck/ist:
• Smooth bottom wire at least 16" above the grtnmd.
• At least 12" between top two wires.
• Top wire 42.n orlowe7.
• Use stays every 6' to 8 •.
• Flag newly constructed portions offence.
TYPICAL 3 AND 4 STRAND CAITLE FENCE
Use Recommended Wire Fasteners
ADJUSTABLE FOUR-STRAND FENCE
Not to scale
Standard Configuration
AD.roSTABLE WIRE FENCES
Adjustable wire fences have specially made clips attached to the posiS that
enable the
wires to be· lowered during times of wildlife migration. Raising
or lowering one or more wires can be the most successful and aflicient
fence modification for elk and deer passage during periods when livestock
are not present The primary dependency on its hind legs for jumping. As
the wire height approaches the lenglh of a deer's legs (approximately 20"),
this dependency on their hind legs nears z.cro.
Lowering the top wire of a 42" fence by 17" and the second wire 5"
reduces bmrier height to about 25". This height can be negotiable by elk
and deer undet virtually all conditions. This type of fencing has the added
benefit of not being damaged by wildlife crossings_
Modification Allowing Neatly Free Movement

7. Effect on Groundwater and Aquifer Recharge Areao.
A potable water supply is not proposed in the property since the land use is for storage of
construction operation and construction materials only and no habitated structures are
proposed on-site.
8. Environmental Effects.
a. Because there will be no grading or dirt moving on the Lay down Yard, as it is already
and existing storage area, the project will minimally affect wildlife.
There are no TESS plants and/or habitats located during survey, therefore no affects on
TESS are expected.
Activities are not likely to impact raptor populations.
b. It hss been determined that no cultural resources occur within the project area. In
general, the region was probably not continuously occupied prehistorically. The
historic background suggests that in the general vicinity, there may have been regional
occupation for as long as I 0,000 yeatS. Permanent American presence in the region
began as early as the 1800's.
No previously recorded paleontological resources occnr within or nearby the proposed
project area.
c. Because there will be no grading or dirt moving on the Lay down Yard, as it is already
and existing storage area, the project will minimally affect wildlife and domestic
animals.
d. There are no uranium deposits or tiulings in the area, and therefore there should be nc
potential rsdiation hazards and defined by the state of County Health Departments.
Fnrthennore, the equipment and materials that will be stored in the proposed site does
not have any known redioactive components.
e. The will be no diesel fuel storage on site. Spill kits will be immediately available to all
operations utilizing fuels and oils. All spills will be properly cleaned up and reported
as required.
9. Trame.
Basic Traffic Analysis provided per Section 4-502 (J)(3).
Please see Tab 10
10. Nuisance.
The noise levels are expected to be in accordance with the Colorado Revised Statutes for
Noise Abatement (CRS 25-12-10 I) and the maximnrn permissible noise levels. Based on the
COGCC ruies, the yard site noise level limits at 350 reet will range between 57-67dbA,
depending on the equipment being nsed. Due to the main activities involving light truck
traffic and minimal heavy equipments activity on site, the noise level is not projected to exceed
80dbA beyond 25 feet of the site boundary, and the noise produced will not be a public
nuisance.
II. Reclamation Plan.
After the yard is no longer needed, the workspace will be returned as near as practicable to
pre-construction condition.

This plan will describe procedures to be followed during the clearing. grading, cleanup, and
restoration precess. These procedures were developed to minimize soil erosion and offsite
sedimentation, return disturbed land to its original contoilr, and to re-establish native vegetation
to all disturbed areas.
2.0 CLEARING AND GRADING
2.1 Clearing
Vegetation will be cleared by hand and/or equipment to facilitate construction of the yard.
Vegetation will be mulched or chipped, then windrowed with topsoil to an edge of the yard
boundaries.
Trees will be cut with a chain saw and/or mechanical shears and brush will be generally cut with
a hydro-axe or similar equipment. Trees and brush will be cut as close to the ground as possible.
Vegetative material will typically be chipped or shredded and incorporated into the topsoil.
Stumps that are not shredded or chipped and incorporated into the topsoil will be removed and
disposed of at an approved disposal facility.
2.2 Grading
Topsoil will be salvaged over the entire disturbed yard. All available topsoil up to a depth of 6
inches will be removed prior to conducting any grading of subsoil.
Topsoil will be stockpiled separate from subsoil and will not be used for any construction efforts.
Dry drainages or washes that cross the construction workspace will not be blocked with topsoil
or subsoil piles. Topsoil and subsoil will be placed on the banks of the drainage. Gaps will be left
periodically in the topsoil and subsoil windowed to avoid ponding and excess diversion of
natural runoff during storm events. Ail level pads and earthen berms will be created with the use
of subsoil.
3.0 RECLAMATION PROCESS
After the yard is no longer needed, all distUrbed portions of the construction workspace will be
returned to pre-construction grades and contours. Subsoil will be returned to match original
contours prior to redistributing topsoil. Topsoil will then be replaced over the entire disturbed
project area from tha approximate area in which it was stripped.

Revegetation will be the primary method to stabilize soils and ensure pennan~nt erosion control
over the long term. Every effort will be made to complete final cleanup and installation of
permanent erosion control measures within 30 days after topsoil is redistributed.
The following sections outline the pre-construction planning and sequential steps for restoring
the construction workspace after use ofthe yard is no longer required.
3.1 Agricultural Features
All cattle guards, gates, and fences will be repaired to at least pre-construction conditions. All
gates, cattle guards, and fences no longer necessary will be removed as directed by the
landowner.
3.1 Rock Disposal
Excess rock is defined as all rock that cannot be returned to the existing rock profile in cuts made
during grading, or is not needed to restore the construction workspace to a condition comparable
to that found adjacent to the construction workspace. Excess rock will be randomly distributed
across the construction workspace, piled or windrowed to create or enhance wildlife habitat, or
arranged to block use of the reclaimed construction workspace by motor vehicles. If not
practical, the Contractor will remove other excess rock from the constroction workspace and haul
it to an approved disposal site. Enterprise will coordinate with the landowner regarding the
methods of disposal.
3.2 Final Cleanup
Within 30 days after reclaiming the yard, the Contractor will make every effort to complete final
cleanup and installation of permanent erosion control structures.
Where soil has been disturbed, the construction workspace will be restored as close to pre-
construction grades, compaction, and other conditions as possible. No solid waste, rock, trash, or
vegetative debris will be buried on the construction workspace.
Final compaction of disturbed areas will be returned to approximate pre-construction conditions.
Any compacted areas will be de-compacted with a scarifier to a depth of 6 to I 0 inches prior to
topsoil replacement and seeding.
3.3 Topsoil Restoration
After the construction workspace is regraded, 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.

Topsoil will be redistributed as close to original salvage depths as possible. 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 an
Entel]lrise-approved and certified weed-free source.
Additional erosion control and soil stabilization will be required in areas adjacent to or within
drainages.
3.4 Permanent Erosion Control
Permanent erosion control methods will be utilized as needed for stabilization of slopes and soils
as described in the Piceance Basin Gathering System Stonnwater Management Plan. Permanent
erosion control measures will be installed within 30 days the yard is reclaimed.
3.5 Rock and Vegetative Debris
Vegetative mulch and excess rock may be used to reduce erosion potential by providing
additional surface relief structure. In areas with a pre-existing rocky surface material, the
Contractor will spread rock over the construction workspace to maintain a surface appearance
similar to that of adjacent undisturbed terrain.
Straw mulch or equivalent will be applied as discussed in the Stormwater Management Plan.
3.6 Seedbed Preparation
The Contractor will scarify, till, or harrow the seedbed to a depth of 3 to 4 inches 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
topsqil replacement to create micro-environments for seed germination and growth, and to
reduce the potential for soil movement.
3.7 Soil Supplements
Gcnemlly, fertilizer will not be used unless requested by the landowner. At this time, no areas
have been identified that require fertilizer.
3.8 Revegetation
Tho Contractor will be responsible for seeding the construction workspace using Enterprise-
supplied seed, appropriate seeding methods, and approved application mtes. The seeding
requirements and scheduling of reclamation activities will be determined in coordination with the
landowner.

3.8.1 Species Selection and Souw
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, post-construction land use objectives, and landowner recommendations. Project seed
will be certified weed-free and will be purchased from and blended by qualified producers and
dealers.
Seed mixes will be purchased from commercial seed vendors and must be statc-<:ertified weed-
free mixtures. Seed bag tags will be collected to confirm that the seed was purchased from a
commercial seed vendor and was tested and certified. Seeding rate will be listed as pounds per
acre of pure live seed (PLS). The Contrector will be responsible for providing all seed tags to the
Environmental Inspector at the end of each day. Proposed seed mixes and rates are identified in
Attachment I.
3.8.2 See<! Aop!jcation Ratm agd Vlab!Hty
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 nsed
within 12 months of testing to assure seed viability. If additional seeding is required in the year
following construction, additional viability tests will be conducted to determine any need for
adjustment of application rates.
3.8.3 Seeding Methods @Dd Procedures
The Contractor will employ broadcast or drill seeding as determined in the field by Enterprise.
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 landowner.
3.8.3.1 Drill Stedlng
Drill seeding is the preferred seeding method and will be employed wherever soil characteristics
and slope allow effective operation of a rangeland seed drill Drill seeding will be performed
perpendicular to the slope. Seed will be placed in direct contact with the soil at an average depth
of 0.5-inches, covered with soil, and firmed to eliminate air pockets around the seeds. Seed will
be applied using a rangeland seed drill with a seed release and agitation mechanism sufficient to
allow seeds of various sizes and densities to be planted at the proper seeding depth.

J.8.J.2 Broadcast Seeding
Broadcast seeding will be employed only in areas where drill seeding is unsafe or physically
impossible. Seed will be applied using manually operated cyclone-bucket spreaders, mechanical
spreaders, ·or blowers. Seed will be uniformly broadcast over disturbed areas. Broadcast
application rates will be twice that of drill rates. Immediately after broadcasting, the seed will be
unifonnly raked, chained, dragged, or cultipacked to incorporate seed to a sufficient seeding
depth. If the area is seeded prior to a soil crust forming, harrowing or raking may not be
necessary.
3.9 Grazing
Gates and fences will be installed along the construction workspace as required. Oates, fences,
and cattle guards will be repaired or replaced after constnJetion as agreed to with the landowner.
These facilities will be left in as good as or better shspe than the pre-construction condition.
4.0 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.
Upon completion of reclamation, Enterprise's Environmental Inspector and Land Agent will
perfonn a fmal inspection of the construction workspace and ancillary facilities to verify that
pre-construction commitments have been satisfied. A daily inspection report will be generated by
the Environmental Inspector which. documents the completion of all final reclamation
requirements.
5.0 POST-CONSTRUCTION MONITORING AND EVALUATION
5.1 Revegetation and Erosion Control Monitoring
During the first growing season following construction and reclamation, Enterprise will conduct
surveys to assess revegetation success, evaluate erosion control measures, and determine the
need for further reclamation.
Revegetation monitoring will include evaluation of the following parameters as compared to
adjacent (off-construction workspace) vegetation:
• percent total herbaceous cover (seeded species plus desirable volunteers),
• new or expanded populations of noxious weeds, and
• species composition.
Areas with poor germination and/or growth will be evaluated to detennine, 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 Enterprise for the first growing
season following construction. Thereafter, Enterprise 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 fll'St year following construction.
Success criteria for both are discussed in Section 5.1.2.
Both erosion control and revegetstion monitoring will be conducted routinely throughout the life
of the pipeline to evaluate long-term survival of reestablished vegetstion and the effectiveness of
erosion control measures with specific attention to problem sites.
5.1.1 Monitoring Agricultural Fields
No agriculture ground is contained within this project.
5.l.2 Evaluating Reclamation Sueces.!
Enterprise is responsible for the stability and revegetation of all areas disturbed as a result of
construction. As discussed in Section 5.1, Enterprise will conduct monitoring after the first
growing season and routinely thereafter to assess soil stability and revegetation success.
Additional seeding will be completed during the llCl<t seeding season (fall or spring). In the event
that first year revegetation is affected by precipitation amounts significantly below the annual
average, Enterprise may request deferment of additional seeding activities until the following
seeding window.
The reclaimed construction workspace 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),
• flow pattern development resulting in rills or gnllies greater than 12 inches in depth , or
• trench subsidence or slumping.
Revegetstion will be considered successful when the following criteria are met:
• total herbaceous (seeded species plus desirable volunteers) cover is at least 70 percent of that
on adjacent land, and
• species composition is comprised of a mix of seeded species and desirable volunteers from
adjacent communities.
5.2 Post-Construction Reporting
Enterprise will continue to conduct storm water inspections of the yard until all final reclamation
requirements have been fulfilled. This will be documented in stormwater inspection reports.

1.0 INTRODUCfiON
This Stonnwater Management Plan (SWMP) identifies operating procedures associated with
stonnwater management for the Enterprise Well Tie Yard (project). These procedures comply
with the requirements, set forth by Colorado Department of Publi~ Health and Environment
(CDPHE), Water Quality Control Division (Division), for controlling stonnwaler d~harges
associated with oonstruooon a®vity.
Pnx:edures identified in 1his plan apply to En~ Produd Operating LLC (Enterprise) and
1he oontractor(s) (Contr~r) it employs to perform constrlldioo and/or maintenance for the
project. Measures in 1his plan pertain to 1he entire project area.
This SWMP describes procedures to minimize the potential for erosion, sedimentation, or the
di~harge of pollutants, by the use of proper oonstru®on teclmiques and the adoption of
appropriate Best Management Pra®ces (BMPs). These BMPs will be implemented and
maintained during all a®ve construooon a®vities and maintained until the terms and conditions
of the associated stormwater permit have been fulfilled.
A COPY of this plan is required by CDPHE, Water Quality Control Division, to be stored on
project from the date of project initlation to the date of expimtion. Upon request, the SWMP is
to be provided to the Division, EPA, or any looal agency in charge of approving plans impacted
by stormwater.
The SWMP, in its entirety, will be retained for a period oftltree years after final stabilization has
be oohieved, all assooiated permit terms have been fulfilled, and a Notice of Inactivation has
been submitted to the State.

2.0 SITE DESCRIPTION
2.1 Nature of Constroetion Aetivitles
The Enterprise Well Tie Yard is used to store construction supplies associated with building the
Piceance Basin Gathering System. The gathering system includes approximately 55 natural gas
pipelines that will be installed over a five year period. The Enterprise Well Tie Yard is
anticipated to be used as a storage yard through 2011.
The Enterprise Well Tie Yard is located in Garfield County at:
• Township 6 South, Range 97 West, Southeast Quarter ofSeetion 2
Vicinity and boundary maps are included in Attachment I.
:U Sequeaee of Major Activities
The Enterprise Well Tie Yard will be constructed as described below:
1.) Preoonstructjon BMP Insta!!atjon -BMPs will be installed prior to commencing grading or
other soil disturbing IWiivlties. Silt fence, straw bales, earthen ben.ns, and/or straw wattle will be
installed along edges of the yard where a risk for material discharge is present. A gravel
approach pad will be installed on the yard entrance if it is anticipated to become a vehicle
tracking control problem.
2.) Clesrlngand Grading-Clearing will remove rocks, logs, and vegetation 1i:om portions of the
yard that will be developed and stores this material for later use during restoration. Vegetation
msy be chipped or shredded by clearing crews rather than windrowed. Grading will remove all
available topsoil from portions of the yard that will be developed. With the topsoil removed,
subsoil will be shaped to creste level areas to be used to store construction materials.
3.) Permooent BMP Installation -More robust BMPs which require less maintenance will be
installed once the yard is graded. These will include earthen berms, sediment traps, and rock
aprons.
4.) Cleanup-Construction supplies and debris will be removed from the yard. Portions of the
yard that were subjected to grading activities, will have subsoil returned to restore original
contours.
5.) Res!oration-Windrowed topsoil will be returned uniformly across the entire disturbed yard.
Topsoil will be seeded with an appropriate seed mix. Mulch or erosion blankets will be applied
to the ROW as needed to protect slopes or other ereas susceptible to erosion. Rocks and
vegetative debris removed during clearing activities will be redistributed over the yard to further
protect against erosion and/or to restrict access.

l.J Acreage Disturbed by Construction Aetlvitles
The Enterprise Well Tie Yard is 2.3 acres in size. It is anticipated that the entire 2.3 acres will be
disturbed by cons1nictlon activities.
l..4 Soil Delcrlption and Potential for Erosion
A custom soil resoun:e report was generated by the Natural Resource Conservation Service to
serve as a reference to soil types loceted within the Enterprise Well Tie Yard. This report
determined that the project area is entirely comprised ofParacbute-Rhone Loams. This soil type
is categorized as well-drained, having low water capacity, with a water table depth of more than
80 inches. Parachute-Rhone Loams have a land capability rating of 6e, indicating they are very
susceptible to erosion .
. The Enterprise Well Tie Yard is located on the Roan Plateau and is situated in rolling hills and
minor intermittent drainages. The original contour of the project area and immediate surrounding
area is characterized by 2 to I 0 percent slopes.
l.S Description of Existing Vegetation
The Enterprise Well Tie Yard is located at 8,335 feet in elevation. Vegetation in the project area
is dominated by Sagebrush, Rabbitbrush, Gambel Oak, Aspen, and a variety of high elevation
mountain grasses and forbs.
Eatimated average ground cover for the project area is 70 percent.
2.6 Potential Pollutant Sources
There are three sources of potential pollutants associated with the construction of and operations
within the Enterprise Well Tie Yard:
• Disturbed Soil -Sediment, vehicle tracking, dust
• Vehicles & Equipment Operation-Fuels, hydraulic and motor oils, lubricants
• Non-Industrial Stomge-Garbage, human waste
Fuels, oils, and lubricants represent a potential risk during refilling/maintenance processes snd in
the event of mechanical failures. Sediment, vehicle tracking and dust will be a potential
pollutant risk on all portions of the project with disturbed soils and on the rosds used to ac<:esS
the project. Garbage snd human waste will be present at dumpster and portsble toilet locations.

2. 7 Non-Stormwater Discharges
There will be two allowable non-stonnwater discharges anticipated during construction and
operation of this· project. Dust abatement to the yard may be performed by applying water to
disturbed soil. Surplus water discharging as a result of these operations will be an allowable
non-stormwater discharge.
Eme.gency Firefighting will involve discharging uncontaminated water and will be considered
an allowable non-11tonnwater discharge.
2.8 Receiving Walen
The Enterprise Well Tie Yard lies within the Circle Dot Gulch drainage. Water discharged from
the project will flow into an un-named, intermittent drainage which is a tributary of Circle Dot
Gulch. Circle Dot Gulch flows into West Fork Panlchute Creek, which in turn flows into
Parachute Creek. Parachute Creek tenninates in the Colorado River. The Colorado River is the
ultimate receiving water.
The project area does not include any municipal storm sewer systems.
3.0 SITEMAP
The Enterprise Well Tie Yard resides entirely within Garfield County, Colorado. Maps are
included as Attachment I depicting the Enterprise Well Tie Yard including the following:
• Construction site boundaries
• All areas of ground surface disturbance
• Areas of cut and fill
• Areas used for storage of building materials, equipment, soil, or waste
• Locations of all structural BMPs
• Locations of all non-structural BMPs
• Locations of springs, streams, wetlands, and other surface waters
Dedicated asphalt or concrete batch plants will not be utilized, therefore will not be depicted on
the site specific maps.

Sediment discharge will be minimized by installing perimeter BMPs, directing accumulated
water off of the project to discharge points, and stabilizing disturbed slopes. Trenches and/or
earthen berms will be installed in areas anticipating high · flows and require a robuat BMP
installation. Trenches and berms will direct water to discharge points which will consist of
sediment trap(s), straw bales, straw wattles, and/or rock aprons. The yard will be shaped to
direct accumulated water to these discharge points or to the trenches and berms that will carry
the water to the discharge points.
Silt fence, straw bales, earthen berms, and/or straw wattles will be installed along project area
boundaries where disturbed or stored soils represent a risk of discharging off-ROW or into a
sensitive resource area. Straw bales, straw wattles, and/or silt fence may also be installed
perpendicular to slopes to slow water velocity, retain sediment, and minimize rilling.
Straw wattles, rock checks, rock aprons, straw bales, silt fence, and sediment traps may be
installed to protect discharge points. Discharge points are sites where stormwater is
intentionally, or unintentionally, allowed to leave the project area. Discharge points may include
the exit side of waterbars, rolling dips, or culverts. Down slope sides of dry, intermittent
drainages, ephemeral drainages, and other natoral topographic features within the project may
also be discharge points. BMPs will be installed to filter sediment, while allowing collected
water to discharge off project while minimizing off-ROW erosion.
Straw wattle will be installed, as needed, perpendicular to cut and fill slopes to minimize erosion
and sediment discharge. Stockpiled earth will have silt fence installed around the entire
stockpile if a discharge risk is present
4.3.2 Non-Structural Practices Cor Erosion 1111d Sediment Control
Non-structural erosion and sediment control practices will be used in conjunction with structural
practices to deliver effective stormwater erosion and sediment control.
Permanent stabilization will be achieved by seeding and applying mulch. All areas of
disturbance will be seeded to establish permanent vegetation when topsoil is returned during the
reclamation process. Mulch will applied to enhance the seeding process or to stabilize slopes to
protect the new seeding. Hydro-seeding will be utilized in areas too steep to seed with
conventional drills or broadcasters.
Slope roughening will be utilized to stabilize areas of cut and fill, where the activity can be
performed safely. In areas of cut and fill where slope roughening is not safe or practical and the
Installation of structural BMPs are deemed ineffective, slopes will be stabilized with straw
mulch, erosion control matting, or a hydro-mulch/tackifler application.

4.3.3 Pluued BMP Implementation
Structural and non-structural BMPs will be installed and/or maintained through all phases of
construction outlined in Section 2.2 -Sequence of Major Activities. The relationship between
the phases of construction and the implementation and maintenance of BMPs is described below:
1.) Preconstruction BMP Insta!!atioo -Preconstruction BMPs will be installed prior to soil
disturbance and will protect sensitive areas from physical damage or receiving sediment or other
pollutant discharge.
Preconstruction BMPs will include silt fence, straw bales, straw wattles, andlor construction
tence which will serve as a barrier between construction activities and sensitive areas. These
BMPs will serve as a visual reminder to restrict activities beyond the installed BMPs and to
minimize the risk of sediment or other pollutants entering a sensltlve area. Preconstruction
BMPs may also be used to create vegetative buffer areas between construction activities and
sensitive areas to further protect against the discharge of pollutants Into sensitive areas.
Preconstruction BMPs will also be installed along edges of right-of-way (ROW) or construction
site boundaries which may be susoeptible to discharging sediment or other pollutsnts offsite.
Preconstruction BMPs will be designed to capture sediment before it leaves the construction site,
while allowing stormwater to exit the area. Areas susceptible to discharging sediment include
dry drainages, flowing streams, areas of cut and till, and sloped portions of the ROW.
2.) Clearing and Grading -Preconstruction BMPs including vegetative buffer strips will
continue to be maiotsined during clearing and grading activltles. Additional silt fence, straw
bales, and/or straw wattles will be installed as necessary to prevent stockpiled soil from
discharging off-ROW and/or to prevent topsoiVsubsoil mixing.
3.) Pennanent BMP Installation -More robust BMPs which require less maintenance will be
Installed once the yard is graded. These will Include esrthen berms, sediment traPS. and rock
aprons.
4.) Cle!ln!!J1-Waterbars may be installed during cleanup to direct stormwater off of the ROW,
minimize surface erosion, and to protect sensitive resources. Slope roughening will be used to
provide additional protection to slopes as original contours are restored. Some or all BMPs
installed in previous phases of construction may be removed during the cleanup phase of
construction.

4.3.8 Groundwater and Stormwater Dewatering
No stormwater or groundwater dewatering will occur within the project area.
5.0 FINAL STABILIZATION AND WNG-TERM STORMWATER
MANAGEMENT
S.l Final Stabilization
Final stabilization of the project will be considered during all phases of construction. AIL things
being equal, choices made during construction will filvor those options that will enhaoce tbe final
stabilization process.
Topsoil will be removed aod segregated prior to performing any excavations or cut and fill
operations. The amount of topsoil removed will be based on individual landowner requirements.
In general, tbc entire topsoil layer will be removed and protected. After contours are restored,
topsoil will be redistributed over tbe entire disturbed ROW in a uniform manner. Compacted
topsoil will be scarified to a depth of 3 to 4 inches to produce a viable seedbed.
All disturbed sites will be seeded with tbe landowner approved seed mix listed in Attachment 4.
Seeding will only occur when soil conditions are conducive and will not occur during muddy or
snow covered conditions. All seed used will be certified weed-free.
Where possible, seed will be incorporated into the soil with tbe use of a no-till or agricultural
drill. In areas unable to be seeded with a drill, seed will be broadcast with manually operated
cyclone-bucket sPfCaders, mechanical spreaders, or blowers. Broadcasted seed will be

incorpomted into the soil with a rake, harrow, cultipacker, or chain. Broadcast seed rates will be
double that of the drill rates. All seed tags will be collected for future reference.
Crimped mulch, tackified mulch, or erosion control matting will be installed as needed to areas
subject to erosion. Permanent waterbars and rock aprons will be installed to direct water off of
the ROW or across the ROW as needed. Rock, logs, and vegetative debris removed during
clearing will be scattered across the ROW to provide additional erosion protection.
Final stabilization is reached wben ali groond disturbing activities have been completed, and
uniform vegetative cover has been established with an individual plant density of at least 70
percent of pro-disturbance levels, or equivalent permanent, physical erosion reduction methods
have been employed.
5.2 ,Loag-Tenu Stonuwater Maaagement
Oversight of long-term stormwater management will be the responsibility of Aspen
Environmental Field Services, LLC (AEFS). The assigned Stormwater Inspector will conduct
monthly inspections of BMPs and note areas of erosion or poor vegetation return. Maintenance
will be performed by AEFS or contractors it employs.
6.0 INSPECTION AND MAINTENANCE
6.1 Inspection
AEFS will provide qualified Stormwater Inspector(s) and/or Environmental inspector(s) to
perform inspections of all BMPs located within the Enterprise Well Tie Yard. Inspectors will
also monitor the restoration process on all disturbed land within tbe project and identifY
additional BMP, seed, and stabilizer requirements. Inspectors will be responsible for completing
inspeetion reports to properly document the implementation of the SWMP.
6.1.1 Construction
In areas of active construction, or areas thet will resume construction, inspections must be made
once every 14 days. Inspections will be made more frequently if necessary to ensure BMPs are
in place and functioning properly.
All BMPs will be inspected within 24 hours of dte conclusion of any precipitation event or
snowmelt event that causes surfilce erosion. If ROW conditions do not allow for timely, post-
storm inspection of BMPs, the inspection will take place within 72 hours of the event and prior
to the re-commencing of construction activities. Any such delays in the inspection of BMPs
must be documented in the Inspection report.

6.1.2 Post-Construction
BMP inspection intervals may be reduced to once a month and post-storm inspections are no
longer required if the following conditions exist:
• All ground disturbance construction ectivities are completed
• All activities identified in the SWMP for final restoration are completed (seeding not required)
• SWMP bas. been amended to indicate areas under rednced inspection intervals
BMPs identified as being insufficient will continue to be properly maintained and/or reinstalled
as necessary. Monthly inspeCtions will continue until final restoration bas been successfully
achieved and these areas are indicated in the SWMP as meeting final restoration requirements.
6.1.3 Winter Inspection Exclusions
Routine 14-day, monthly, and post-storm inspections are not required for those areas where
construction activities are temporarily halted, mow cover exists over the entire site for an
extended period, and melting conditions are not present. This exclusion should be properly
documented in inspection reports indicating: dates when snow cover occurred, date when
construction activities ceased, and date melting conditions began.
6.2 Maintenance
AEFS is responsible for overseeing BMP instsllation and/or maintenance. Maintenance of
BMPs will be perfonned within 72 hours of discovery or notification.
BMPs that have failed due to improper BMP selection, improper installation, insufficient
maintenance, or due to a significant weather event must be maintained, repaired or replaced
within 24 hours of discovery or notification. The SWMP must be updated to include any newly
installed BMPs.
Maintenance of silt fence, straw wattles, straw bales, rock checks and sediment traps will be
required once the BMP has reached 500/o of its sediment retsining capabilities or tbe structural
integrity of the BMP is compromised. Maintenance will involve removing the captured sediment
from the BMP and returning it to the ROW and/or making the necessary repairs to correct
structural problems.
Maintenance will be performed to rock aprons, crimped mulch, hydro-seed, and erosion control
matting as soon as the failure of any of these BMPs are allowing erosion channels to form.
Maintenance of rock aprons will involve removing the eroded channel and resrranging the rock
or adding additional rock to prevent future failures. Maintenance of crimped mulch, hydro-seed,
and erosion control matting will consist of removing tha eroded channel, reseeding the damaged
area, then reapplying mulch, hydro-mulch, or erosion control matting.
