1.0 INTRODUCTION
The following Stormwater Pollution Prevention Plan provides the erosion, sediment , and
stormwate r pollution contro l practices to be implemented and maintained during p ipeline
construction activities for the Canyon Gas Resources, LLC (CGR) Porcupine Loop project in
western Colorado.
The risk of stormwater, erosion, and sediment pollution is minimized by the use of appropriate
construction methods and equipment and the short duration and limited area involved. The
erosion, sediment, and stormwater pollution control practices prescribed herein further avoid or
reduce the impact of soil erosion, sedimentation, and stormwater pollution on or adjacent to the
proposed project right-of-way. This plan includes standard stormwater, erosion, and sediment
pollution control measures that are proven and in widespread use where applicable by the natural
gas pipeline industry.
This plan applies to pipe line construction, aboveground faci lities, and any necessary
modifications to existin g access roads .
CGR and co ntractor personnel are to be thorou ghly familiar with this p lan and its co n ten ts prior
to initiatin g construction on th e Porcupine Loop proj ect.
2.0 PROJECT SCOPE
2.1 PROJECT DESCRIPTION
CGR has applied to the Bureau of Land Management (BLM) for a right-of-way grant under
Section 28 of the Mineral Leasing Act of 19 2 0 , as amended, to authorize the construction,
operation, and maintenance of a 12 -i nch diameter natural gas pipeline and related facilities in
Garfield County, Colorado. The proposed pipeline project would loop an existing CGR 6-inch
diameter natural gas pipeline and would connect CGR's Bentley and Porcupine Gathering
Systems. The pipeline would transport existing and future natural gas produced by Tom Brown,
Inc. (TBI) in the Rifle, Co lorado area for processing at the Rifle Clough Compressor Station .
TBI plans to drill more than 40 new wells in 2004, all of which are dedicated to CGR's gathering
systems. Production from these wells is expected to increase by 35 mmscf/d, increasing total
throughput from 15 mmscf/d to 50 mmscf/d. System throughput will increase to 100 mmscf/d in
the n ext four years . The proposed pipeline will de-bottleneck the existing gathering systems and
will ensure sufficient capacity to carry CGR's current projection of future gas volumes.
The project is approximately 4 .3 miles in length , of which 0 .8 miles are located on fee-land s and
3.5 miles are located on BLM lands administered by the G lenwood Springs Field Office. The
proj ect is located south and wes t of Rifle, Colorado in Section s 1, 9, 10, 11 , and 12 of Township
7 So uth, Range 94 West in th e Rulison and North Mamm Peak USGS Qu adra n gles . Proj ec t area
map s are included in App endi x A.
•
•
•
CGR will design and build the pipeline in accordance with th e National Electrical Code,
Department of Transportation, Title 40 CFR Part 192, and ASME B31.8 standards . Faci liti es will
b e d es igned, constructed, and operated in comp liance wi th th e Occupational Health and Safety
Act (OSHA) regulations pertaining to pipelin e construction and operation .
The right-of-way cons tru ction width wi ll be 50 feet. A launcher and receiv er wi ll be lo cat ed at
opposite ends of the pipeline, with risers, blow-downs, and valve sets where appropriate along the
right-of-way.
2.2 CONSTRUCTION SEQUENCE
Construction activities are expected to be completed in 4 to 6 weeks and are scheduled for
summer or fall 2004.
2.2.1 Pipeline Construction
The standard open cut constructio n method wi ll b e us ed to install the pip e lin e. Th is method
includes clearin g, grad in g, trenchin g, pipe stringing, pipe b ending, welding, joint coatin g,
padding where required, low eri n g in, backfi llin g, pneumatic t es tin g, cleanup, and revege tation .
C learin g, topsoiling and grading will be limited to the minimum area required for safe and
effic ient construction. C l earing will b e p erformed only to th e ex tent nec essary to allow for
construction activities. The gro und surface will not be grubbed or c leared of vegetation less than
four inches in h eight when possible. Every effort will be made to salvage root sys tems. Large
vegetation, such as trees and shrubs, wi ll be cleared from the right-of-way and stockpi led or
windrowed at the edge of the approved workspace for later use in reclamation.
Topsoil will be removed and stockpiled . Where topsoil is available, the top 4 to 6 inches of soil
will be removed over the trenchline and in areas requiring grading. Topsoil and cleared
vegetation will be stockpiled together on BLM lands . Topsoil will be stockpiled separate from
cleared vegetation on fee-lands . The right-of-way will be graded only to the extent necessary to
create safe and efficient pipeline installation conditions . Topsoil will not be salvaged over the
existing CGR pipelines.
The ditch will be excavated and sloped in accordance with OSHA specifications. The cover from
top of pipe to ground level as graded to pre-construction contours will be in conformance with
DOT regulations . Cover will typically be 36 -inches in depth . Greater depths of cover will be
required at road crossings, foreign pipeline crossings, and waterbodies. As a minimum, the ditch
will be excavated to a depth to allow a clearance of 18 inches between the CGR p ip eline 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 authori zed by the pipeline
owners/operators. Ex isting pipeline locations will be marked in th e field and 48-hour prior
notifi cation give n to th e operator of th e und ergro und utilit y .
Where rock is encountered, tractor-mount ed m ec hanical ripp ers or rock trenching equ ipment
may be used to faci litate excavation.
2

The trench will b e excavat ed and subsoil material stockpil ed separat el y from topsoil stockp il es.
Based on field conditi ons, gaps wi ll be made in topsoil and subsoi l stockpi les to avo id ponding
or excessive diversion of natural runoff during storm events .
Pipe installation will include stringing, bending for hori zo nt a l or vertical ang les in th e ali gnment,
welding th e pipe segmen ts together, x-ray inspection, coatin g the joint areas to prevent corrosion,
and then low ering-in and padding as described in greater detail below.
Pipe will be hauled by truck to the pipeline ROW. Each joint of pipe will be unloaded and placed
parallel to the ditch.
After the joints of pipe are strung alon g the ditch, individual joints of pipe wi ll be bent to
accommodate horizontal and vertical changes in direction. Fie ld 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 .
After th e pipe joints are bent, th e pipe is line d up end-to-end and clamped into position. The pipe
is then weld ed in conformance with 49 CFR Part 192 , Subpart E. "Welding of S te el P ipelin es"
and API 1104 , "Standard for Welding Pipelin es and Re lated Facilities".
Welds wi ll be visually inspected by a qualified inspector and by nondestructive radiograp h ic
methods . At a minimum, rad io grap hi c inspection will b e conducted in accordance with DOT
req ui rements . A specialized contractor, certified to perform rad io graphic inspection, wi ll be
emp loyed to perform this work. Any defects will b e repaired or c ut out as requ ired under the
specified regu lation s and standards .
To prevent corrosion, th e pipe will be ex ternally coated with fusion bonded epoxy coatin g prior
to delivery. After welding, field joints will be coated with either tape and primer or shrink
sleeves. Before the pipe is lowered into the ditch, the pipeline coating wi ll be visually inspected
and tested with an electronic detector, and any faults or scratches will be repaired.
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 th e ditch. Specialized padding machines will be
used to sift soil fines from the excavated subsoil to provide rock -free pipeline padding and
bedding. In rocky areas, padding material or a rock shield will be used to protect the pipe .
Topsoil wi ll not be used to pad the pipe .
Backfi ll ing will begin after a sec ti on of the p ipe has been successfu ll y placed in the ditch and
fina l inspection has been comp l eted. Backfi ll ing will be conducted using a bulldozer, rotary
auger backfill , padding machine or other suitable equipment. Backfi llin g the trench will
ge nerally u se the s ubsoil previously excavated from th e tr enc h , excep t in rocky areas where
import ed se lec t fill material maybe needed. Backfi ll will be graded and co mp ac ted, where
necessary for ground stability, by being tamped or walked in with a wheel ed or track vehicl e.
3
•
•
•
Compaction will be performed to th e ex tent th at there are no voids in th e tren ch . Any excavated
materials or materials unfit for backfi ll wi ll be util ized or properly disposed of in confonnance
wi th app li cab le laws or regulations.
Cleanup and restoration will begin as soon as possible after backfill activities are completed. The
right -of-way will be graded to the original contours and natural runoff and drainage patterns will
be restored. Topsoil will be redistributed over the trench and other portions of the right-of-way
from which the topsoil was salvaged and permanent erosion control measures will be installed.
Disturbed areas will be seeded with seed mixes approved by the BLM and fee-landowner.
2.3 ESTIMATED DISTURBANCE
The approximate area of temporary disturbance for construction within the right-of-way is 26
acres and total temporary disturbance is 29 acres. Table 2.3 below describes the width, length
and acreage of the right-of-way (ROW), and acreage for temporary use areas (TUA), and
dis turb ed areas (DA) that wi ll be used during construction.

2.4 SOIL DATA AND RUNOFF COEFFICIENT
The project crosses through the following soil mapping units :
Morval-Tridell complex, 6 to 25 percent slopes, are moderately sloping to hilly soils on alluvial
fans and sides of mesas that are formed in reworked alluvium derived from basalt and sandstone.
The Morva! soil makes up 55 percent of the unit and occurs on less sloping parts of the landscape
and the Tri dell soil makes up 30 percent of the unit and occurs on the sides of mesas. The Morval
soil is deep and well-drained, with a loam surface texture and clay loam, stony c lay loam, and
stony loam subsoil textures. The Tridell soil is deep and well -drained, with a stony loam surface
texture and a very stony loam subsoi l texture .
Nihi ll chann ery loam, 6 to 25 percent slop es, is a moderate ly s lopin g to hilly so il on alluvium
deriv ed from Green River shales and sandstone s. The soil is d eep and well -drained, with a
chann ery lo am surface t ex ture and very chann ery lo am, ex trem e ly channery sandy lo am and
4

ex tremely channery lo am subsoil textures.
Torriort hents-Camborthids-Rock outcrop comp lex, steep, are exposed sandstone and shale
bedrock, loose stones, and soils that are shallow to deep over sandstone and shale bedrock and
stony basaltic alluvium. Torriorthents make up 45 percent of the complex, Camborthids make up
20 percent, and Rock makes up 15 percent. Torriorthents are located on foothills and
mountainsides below rock outcrops and Camborthids are located on lower toe -slopes and
concave open areas on foothills and mountainsides . Surface textures are clayey to loamy and
include variable amounts of gravel, cobble, and stones in the substratum or on the surface .
Torriorthents-Rock outcrop complex, steep, are exposed sandstone and shale bedrock, and stony
soils that are shallow to moderately deep over sandstone and shale bedrock and stony basaltic
alluvium . Torriorthents make up 60 percent of the complex and Rock outcrop makes up 25
percent. Isolated areas of Nihill and Tridell soils are included in this mapping unit. Torriorthents
are on foothi ll s and mountainsides below the rock outcrop. Surface textures are c layey to loamy
and include variab le amounts of gravel , cobble, and stones in the substratum or on the surface.
T h e soil type s and environmental parameters are su mmarized in Table 2.4 below .

The mnoff coefficient values ("C values") are the percentage of precipitation volume that is not
absorbed by the surface. Morval-Tridell complex and Nihill channery loam soils are classed in
hydro logic group B and have a moderate rate of water transmission . Torrio1ihents-Camborthids-
Rock o utcrop complex and Torriorthents-Rock outcrop complex are not classified in a
hydrologic gro u p . The runoff coefficient for the project area prior to construction is between 0 .32
and 0 .54. The mnoff coefficient for th e project area after construction would increase due t o loss
of vegetation, but woul d return to preconstru c tion l evels as the ri ght -of-way revegetates and
stabilizes to preconstmction vegetativ e ground c over conditions.

2.5 VEGETATION
The proposed pipeline project would cross through areas of mixed mountain shrub, sagebrush
scrub, and pinyon -juniper wood land, and meadow . Percent vegetative groundcover varies
betwe en vegetation types. Th e vegetation types and th eir dominant species and es ti mated p ercent
vegetative groundcover are li sted in th e following tabl e.

2.6 POTENTIAL POLLUTION SOURCES
Activities associated with construction of the project that may affect storm water include c learing
and grading; access road modifications; vehicle operation, maintenance and fueling; painting
aboveground facilities; coating pipe joints; and herbicid e application to control noxious weeds .
The following materials may be used during construction of the proposed project and could
affect the quality of stormwater discharges if not managed correctly :
• Petroleum based products • Herbicides
• Lubricants • Vegetative and woody debris
• Paints and coatings • Disturbed soil
• C leaning solvents
Soi l disturbed by construction is the most likely potential po ll ution source and is addressed by
the erosion and sediment contro ls in Section 4.1. The potential for accidental spills or leaks will
be minimized by adherence to the Spill Prevention, Containment, and Countermeasure (Spill)
Plan, which is summarized in Section 4.2.
2.7 NON-STORMWATER DISCHARGES
Construction dewatering is the only non-stormwater discharge that may occur from the project
area during the constru ction period. Construction dewatering may be required when groundwater
and/or stormwater enters the trench. Dewatering shall be accomplished by pumping water from
the trench at a contro ll ed rate that prevents erosion and sedimentatio n. Water will be disc harged
in a well-vegetated, upl and area and will not be pumped directly into flowing waterbod ies.
Dewatering will occur in accordance with applicable permits.
2.8 RECEIVING WATERS
The proposed project crosses Porcupine Creek, one intermittent tributary to Porcupine Creek,
and two intermittent tributaries to Spruce Creek . The project does not cross any wet lands . The
6
•
•
•
project area is located within the Lower Colorado River basin. All waterbodi es are expected to
b e dry during th e constru ction period .
3.0 PROJECT MAPS
Proj ect maps are included in Appendix A. The project maps present the construction right-of-
way boundaries, access roads, surface waterbodies, and elevation contours. Drainage basins and
potential structural stormwater pollution prevention measures are drawn on the project maps.
4.0 BEST MANAGEMENT PRACTICES
Best management practices (BMPs) will be used to minimize erosion and sediment transport
during the construction activities associated with the proposed project. General construction
stages of th e proposed project and changes in site erosion potential and stormwater runoff that
accompany each stage are described below.
Stage 1: Pre-C onstruction-Sto rm wat er runoff from the site is at pre-developed lev e ls and
eros ion is minimal. Sit e perimeter erosion con trol s may b e required prior to initial disturbance.
Stage 2: Clearing-Erosion from the site increases to moderate leve ls and stormwater runoff
volume begins to increase as vegetation is removed and site areas beco m e compacted by heavy
eq uipment. At this stage, th e installation of best management practi ces may be necessary.
Stage 3: Topsoiling and Grading-Topsoilin g and grad in g can result in moderate to hi gh leve l s
of eros ion . Major storms can wash away sed im ent contro l structures and can deposit substantial
sediment in control structures, significant ly reducing capacity. Runoff volume is increasing as
disturbed area increases. Erosion can continue to be moderate to high and stormwater runoff
volume continues to increase as disturbed areas become more compacted. Installation of best
management practices is necessary . Regular inspection and maintenance of sediment control
structures is required to maintain effectiveness of the devices .
Stage 4: Active Construction-Construction is at its peak . Moderate to high erosion rates can
continue and stormwater runoff volumes can approach maximum. The impact of high erosion
rates can be significant if sediment control practices have not been maintained during previous
stages of construction and are clogged or have inadequate capacity to control site stormwater
discharges .
Stage 5: C lean up and Reclamation-Disturbed areas are res to red to original contours, seeded,
and stabi li zed, as necessary, with vegetation or other suitab le non -ero sive cover. Once all areas
of th e site are stabilized, temporary sediment control measures will b e removed from th e sit e,
and sediment co ll ec ted during the cons tru ction phase is removed from permanent stormwater
co ntro l structures to restore d es ign capacity, if n ecessary. Stormwater runoff volume reaches
post -development rates and may be less than the volume that occurred in Stage 4, due to areas of
the site that are stabilized with vegetation.

4.1 EROSION AND SEDIMENT CONTROLS
The potential for eros ion and sediment transport is greatest in areas where ground surfaces hav e
been disturbed and soil i s exposed to physical age nts such as wind and water. In an effort to
protect existin g water quality, both temporary and permanent BMPs and other erosion control
measures have been designed to minimize the effects of eros ion caused by stormwater runoff. In
most cases, a comb in ation of vegetati ve, structural, and stormwater management practices are
used to contro l erosion and transport of sediment. Typ ical BMPs drawings are included in
Appendix B.
Erosion and sediment contro ls will be used and maintained during all phases of construction .
Selection of appropriate erosion contro ls will be selected based on soi l properties, steepness of
the slope, and anticipated surface flow or runoff. A ll control measures will be maintained as
necessary until the general perm it is terminated.
4.1.1 Structural Practices
During construction, erosion and sediment contro l structures including waterbars and sediment
barriers w ill be employed as necessary to reduce erosion and runoff from the cons truction
workspace to adjacent areas .
4.1.1.1 Sediment Barriers
Sediment barriers prevent sediment flow and erosion of dis turbed areas . Sediment barriers may
inc lude si lt fence, straw bales, excelsior logs, or sandbags.
Sediment barri ers are typi cally installed at the base of slopes at road cross in gs or s lop es adjacent
to flowing waterbodies, and around topsoil or subso il stockpiles at flowin g waterbodies.
Sediment barriers will be installed at the direction of the on-site CGR representative .
Specifications for the installation of silt fence and straw bale barriers have been included in
Appendix B. To be effective, the bottom of the silt fence shall be imbedded into the soil surface
at a minimum depth of six inches . The straw bales shall be imbedded into the surface soil at a
minimum depth of four inches and will be double-staked with wooden stakes .
Sediment will be removed from the sediment barriers when capacity is reduced to 50 percent of
original. Sediment barriers may be removed from the construction right -of-way if replaced by an
equivalent BMP or once the final stabilization criteria has been met.
4.1.1.2 Slope Breakers
Slope breakers (waterbars) are utilized for the purpose ofreducing the ve locity and concentration
of runoff and disp ers ing runo ff to prevent excessive sheet erosion and formation of a gully
resulting in transport of sediment off of the right -of-w ay onto adjacent areas. Waterbars sha ll be
ins ta ll ed in s loped areas su scep tib le to eros ion an d co n stru cted as berms made fr om dis turb ed
so il m at eri a ls within th e co n stru ction right -of-way. T ops oil wi ll n ot b e used to co nstru ct
waterbars. Sp ec ifica ti on s for in stall ation are in c lud ed in App endi x B.
8
•
•
•
Drainage or outfall from waterbars shall be direct ed into natural drainage swales and stable ,
well -vegetated areas. The drainage from the slope breaker outlets may be furth er controlled with
energy-diss ip ati n g devices which may include rock or sediment barriers as specified in Section
4.1.1.1 based upon site-specific conditions.
Slope breaker spacing is primarily dependent upon th e slope of the right-of-way, the soil erosion
potential, and the general right-of-way configuration. Temporary waterbars will be installed at
the base of slopes adjacent to flowing waterbodies and in sloped areas susceptible to erosion.
Temporary spacing will be determined based on site-specific conditions and as directed by the
CGR Representative. Permanent waterbars will be installed across the right-of-way after topsoil
replacement. Permanent waterbars will typically be installed at the following spacing intervals:
Slope%
5-15
15 -3 0
30+
Spacing (feet)
300
200
100
Permanent waterbars will be install ed w ith a 2 to 8 percent outfall to facilitate drainage off of the
right-of-way into stable, well-vegetated areas. Permanent waterbar spacing and outfall may be
adjusted by th e CGR Re presentative based on s ite -specific co ndition s .
4.1.2 Non-Structural Practices
Non-structural (stabilization) measures wi ll be implemented during cl eari n g, clean-up and
revegetati on ac tivities .
4.1.2.1 Clearing
As discussed in Section 2.2.1, clearing will be performed only to the extent necessary to allow
for safe and efficient construction activities. The ground surface will not be grubbed or cleared of
vegetation less than four inches in height, as practical. If the ground surface is cleared of
vegetation, root stock will be preserved and stockpiled with salvaged topsoil. Large vegetation,
such as trees and shrubs, will be cleared from the right-of-way and extra workspace areas and
stockpiled or windrowed at the edge of the approved workspace for later use in reclamation.
4.1.2.2 Cleanup
All construction-related debris (except vegetative debris) will be removed and disposed of at an
approved disposal area. The right -of-way and temporary extra workspace areas will be graded as
near as possible to the pre-construction contours and natural runoff and drainage patterns will be
restored. Stockp iled topsoil will be redistributed over the trench and other portions of the right -
of-way from which the topsoil was salvaged. Topsoil will be left in a roughened condition.
Permanent waterbars will installed according to th e guid elin es in Section 4 .1.1.2 .
Vegetative mulch and excess rock may be used to reduce erosion potential on BLM -lands by
providing additional surface relief structure. Vegetative debris salvaged during clearing and
grading operations will be dist1ibuted across the right -of-way. Layering of rock may be us e d on

th e surface of erodible soils in some critical areas to r educ e erosion and restore appearance of
n ativ e surface. Suit abl e si t es include n at urally rocky s lopes and areas that h ave a natural grave l ,
cobb le, or boulder veneer on the surface. S uitable sites wi ll be determined by the CGR
Represen tati ve in conjunction with the BLM on BLM-designated lands .
C leanup activities will be initiated as soon as practicable after backfilling activities have been
completed .
4.1.2.3 Revegetation
Every attempt will be made to seed disturbed areas within 24 hours of completing topsoil
replacement and installation of permanent soil erosion and sediment control measures.
All disturbed areas will be reseeded with the appropriate seed mix and rates by vegetation type as
determined by the BLM and presented in the Environmental Analysis.

4.2.1 General Spill Control Measures
To prevent the accident al re lease of h azardo us materials and petroleum products, construction,
operation, and maintenance activities shall comp ly with CGR's Spi ll Plan . Th e Spill Plan is
incl ud ed in Appendix C and is summarized in the sec tions below. CGR's Spill P lan:
• Identifies emergency notification and state agency names and phone numbers that shall be
contacted in the event of a spi ll ;
• Requires sufficient supplies of absorbent and barrier materials on hand to allow for rapid
containment and recovery of spills; and
• Includes instructions for the collection and disposal of waste, soil, and other materials
generated during, and clean-up of, a spi ll.
Th e following precautions shall be taken to ensure that a re lease of petroleum and hazardous
material s is prevented or con tained:
• A primary emergenc y coordinator for hazardous materials man agement and emergency
response wi ll be designated . Two alternates will also be id en tifi ed. Primary and a lt ernate
emergency coordinators will be knowledgeable of the chemicals and processes invo lved
during construction and will hav e stop work authority to prevent imp ac t s to environm ental
resources .
• All proj ect perso nn e l wi ll be required to receive basi c spill prevention trammg, and a ll
personnel who will be invol ved with the transportation and storage of fuels or hazardous
sub stances, equ ipm ent maintenance, and spi ll response wi ll be provided wi th additional spill
prevention and response training .
• The CGR representative will inspect the construction right -of-way and construction storage
yard frequently to ensure proper use , storage , and disposal of material.
• All materials will be stored in a neat, orderly manner in their original containers with the
original label. Containers larger than 55 -gallons will be stored in secondary containm ent
structures that allow for 110 percent capacity plus potential precipitation .
• Fueling and maintenance activities will be performed in upland areas and will not be
performed within I 00 feet of a flowing waterbody. Bulk materials will be stored in an
approved construc ti on yard and wi ll not be stored within I 00 feet of a flow ing waterbody.
• Eq uipm en t and vehi c les sh all be inspected daily for leaks and receive regul ar preventati ve
maintenance to reduce the potentia l for leakage.
4.2.2 Additional Sp ill Control Measures
Spills of hazardous materials and petroleum products shall b e reported to th e appropriate federal
and state agency if reportable quantities ar e exceeded .
I I
•
•
•
Material Safety Data Sheets will be avai lab le for any hazardous material on th e constmction
right-of-way or storage yard .
Equipment maintenance and fueling and herbicide application will only occur in upland areas at
least 100 feet from flowing waterbodies. Hazardous materials, petroleum products, lubricants,
paints and coatings will not be stored within 100 feet of flowing waterbodies. If topographic or
site-specific conditions do not allow for station ary equipment, such as pumps or generators, to be
placed in upland areas, the stationary eq uipment shall be stored in secondary containment
structures in accordance with the Spill Plan.
4.3 FINAL STABILIZATION AND LONGTERM STORMWATER MANAGEMENT
Measures used to achieve final stabilization have been addressed in Section 4.1.2 and measures
to control sediment pollutants in stormwater discharges have been addressed in Section 4.1.1.
After constmction has been completed, no petroleum or chemical products or hazardous
materials wi ll be used on or stored in the constmction right-of-way and construction storage
yard; therefore, no additional measures are required to prevent these materials from entering
stormwater di sc har ges.
4.4 OTHER CONTROLS
In addition to requirements in the Spill P lan and installation of ero si on and sediment control
measures, the fo ll owing good hous ekeepin g practices will b e imp lemented to prevent or
minimize potentially polluting cons tru ction materials from co nt act with stormwat er:
• Construction of the project will be scheduled during the dry season to minimize stormwater
pollution potential and to control pollutants in the stormwater discharges.
• All project-related personnel will receive environmental training which will include spill
prevention and control procedures, and sediment and erosion control measures.
• Dust abatement measures will be implemented for control of airborne dust along the
construction right-of-way and on unpaved access roads, as requested by the BLM, fee-
landowner, or Garfield County representatives. Unpaved access roads, and topsoil and
subsoil stockpiles will be sprayed with water or an approved tackifier, as needed, to minimize
the effects of wind erosion and to reduce fugitive dust.
• Regular disposal for garbage, rubbish, constmction wastes, and sanitary waste will be
maintained at all times during construction. Sanitary sewage facilities (portable chemical
toil ets ) will be provided at all work locations . Sanitary waste will be collected and removed
for disposal at an appropriate licensed sewage disposal faci lit y .
12
• 5 .0 MAINTENANCE AND INSPECTION
5.1 MAINTENANCE
The construction contractor awarded construction will be responsible for the implementation and
maintenance of this plan. The CGR Representative will be responsib le for ensuring that the
construction contractor is in compliance with this plan. Maintenance will be performed on an as-
needed basis based on the results of inspections conducted at the construction storage yard and
along the construction right-of-way.
All erosion and sediment controls and other protective measures identified in this plan will be
maintained in an effective operating condition. If site inspections indicate that BMPs are not
operating effectively, maintenance will be performed promptly, within 24 hours and before the
next anticipated storm event, to maintain continued effectiveness of stormwater pollution
contro ls.
5.2 INSPECTION
5.2.1 Cons t ruction
• During con struction , th e CGR Re presentati ve will insp ect th e disturbed con stru ction ri ght -of-
way and c onstru ction sto r age yard at le ast once every 14 c al endar d ay s and w ithin 24 hours o f
any p rec ipit ation or snow m elt event that c au se s surfac e ero sion . F ollowin g eac h insp ec tion , th e
CGR Represe nt ative wi ll comp lete an Erosion Contro l Inspec ti on Form and Hazardo us Materials
Inspec tion Form (included in Appendix D) to document results of the inspection. Copies of
inspection reports wi ll be retained at the construction site. After the project has been completed,
copies of the inspection checklists will be retained at CGR's office.
•
If design capacity of any erosion control structure has been reduced by more than 50 percent,
corrective action will be taken within 24 hours of discovery or as soon as weather or ground
surface conditions will allow. If equipment or storage containers are leaking, the equipment or
storage container will be repaired immediately.
An "Incidence of Noncompliance" report will be completed by the CGR Representative for any
violation of the stormwater pollution prevention plan observed during any inspection conducted.
The report will include infom1ation on the cause of noncompliance, the corrective action taken to
prevent further causes of noncompliance, and a statement detailing any environmental impact
that may have resulted from the noncompliance.
5.2.2 Post-Construction
CGR will in sp ect th e ri ght -o f-way in th e sp rin g aft er c ompl etion of con stru ction and r evege t ation
activiti es to evaluat e the effectiv enes s of th e erosion and sedim entation control m e asur es . Areas
of activ e erosion would b e repai re d and reseeded as discu s sed in Sec tion 4.1.2.2 of this p lan .
13
•
•
•
Final stabili zation of the constru ction project will be considered compl eted once it h as been
determined by the CGR representative that the project area has regained 70% of the background
vegetative cover. An Inactivation Notice can then be filed for the NPDES permit. An
Inactivation Notice is included in Appendix E . Copies of all records and information resulting
from monitoring activities required by this permit will be retained by CGR for a minimum of 3
years .

(emergency plann ing), Sec tion 304 (emergency re lease notification), and Section 311 and
312 (community right -to -know reporting req ui rements)
Thi s plan is int end ed to comply with and c ompliment ex isting r egulations p ertainin g to th e s afe
u se of hazardous mate1ials . Pe rsons responsible for handling hazardous materials for this proj ect
will be train ed in the proper use/management of the materials and will b e familiar with all
•
•
•
applicabl e laws , polici es, proc edures , and b est manage m ent practi ces (BMPs) re lat ed to them.
2.0 TRAINING
Th e Contrac tor wi ll provide basic hazardous materia ls management, spill prevention and
response training to construction and inspection personnel. Additional training will be provided
to all personnel who will be invo lved with the transportation and storage of fuels or hazardous
substances, equipment maintenance, and spill response. 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. The Contractor is required to maintain a record of those workers who have received
training. At a minimum, this training will include the following :
• a discussion of individual responsibilities;
• an overview of all regulatory requirements;
• meth ods for the safe han dli n g and storage of hazardous materials and petroleum products;
• spill preventi on procedu res;
• op eration and lo c ation of spill control mat eri als;
• in sp ect ion pro cedures fo r spill co nt ainm ent equipm en t and m aterials;

• u se of personal protec tiv e equipment and spill c leanup equipm ent ;
• procedures for coordinatin g with em ergenc y re spon se team s; an d
• ag ency notific ation requi rem ent s.
3.0 HAZARDOUS MATERIALS MANAGEMENT
Construction, operation, and maintenance of the project will require the use of certain potentially
hazardous materials such as gasoline, diesel fue l, lubricating oils, hydraulic fluids, paints, and
solvents. 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. Hazardous materials will be stored in the construction storage yard and
not on the right-of-way. When transported, stored and disposed of properly as described below,
the risks associated with these materials can be reduced substantially.
3.1 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
pertinen t requirements . Hazardous materials wi ll be transported in DOT approved containers at
all times. Prior to transporting hazardous materials, appropriate shipping papers will be
comp leted . Ve hi cles carrying hazardous materia ls wi ll be equ ip ped wi th cleanup materials to
contain a sm all spill should one o cc ur durin g tran sport In addition , ve hi cles tran sportin g s u ch
materials will be properly sign ed (placard e d) and/or marked . Prior to transporting hazardou s
material s, vehicle s will b e inspected for leakag e and other potential safety probl em s. The
Contractor will ensure that vehicle drivers are properly train ed to respond to and report spill s,
2

leak age, an d/or acc id ents in vo lvin g h azardou s m aterials (see Secti on 2.0).
A ll h azardo u s materials u sed for th e proj ect wi ll be properly co nt ain erized and lab e led at all
times, inc luding during transportation . Smaller DOT approved containers will be used on -s ite 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.
3.2 HAZARDOUS MATERIALS INVENTORY
The Contractor will provide a complete inventory to CGR of all substances that will be used
during construction of the pipeline. The inventory will include a list of all fuels, oils and
hazardous substances that are typically expected to be on-site during construction, quantities
stored on-s ite, and the federal and state reportable quantities for each substance. The Contractor
will also provide the MSDSs for fuels, oils, and hazardous substances to be utilized during
construction activities which, if re leased, may pose a threat to human health or the environment.
Hazardo us m aterials th at w ill be u se d d uri n g co n struction , operati on, and maint en ance of th e
proj ect w ill b e id enti fied on th e Hazardo us Sub stances Inventory Form in cl uded in Appendix A.
3.3 STORAGE OF HAZARDOUS MATERIALS
Hazardou s m ateri als, petro leum pro du cts, lub ricant s, paints an d coatin gs w ill no t b e stored
within 100 feet of any waterbody. If topographic or site-specific co n ditions do not a ll ow for
stationary equipment, such as pumps or generators, to be placed in upland areas, the stationary
equipment shall be stored in secondary containment structures in accordance with the Spill Plan.
Cleanup materials, including absorbent spill pads and plastic bags, will also be stored in these
areas.
3.3.1 Storage Requirements
Security: Hazardous materials will be stored in secure areas to prevent damage, vandalism
and/or theft. During construction hours , hazardous materials may be stored temporarily on the
right-of-way but overnight storage on the right -of-way will be prohibited. All storage containers
wi ll remain sealed when not in use and storage areas will be secured (gated, lo cked, and/or
guarded) at night and during non-construction periods .
Co ntainers: Containers will be compatible with th e hazardous materials or wastes stored. If the
container leaks or becomes damaged, the substance must be transferred to a container in good
condition. The Contractor will inspect containers at least weekly to discover any leaks in the
containers or the containment systems. Containers used for transportation m ust comply with the
DOT req ui rements , inc lu ding th ose in Tit le 49, CFR, Part 173. Containers ho ld ing h azardous
sub stan ce s will b e ke pt clo sed durin g tran sfer and storage, except w h en it is n ecessary to a dd or
remov e th e sub stan ce. C ontain ers 55-gallon s or gr eater will b e stored on p all ets and s urround ed
b y s ec ondary containm ent.
3

•
•
Secondary Containm ent : Sec ondary containment will includ e, but w ill not b e limited to, a
portable containment system constructed of steel , PVC or other suitable material or bermed or
diked areas that are lin ed with a minimum of 10 mil thick polyethylene . Secondary con tainm ent
structures must b e capab le of holdin g 110 percent of the vo lum e of th e stored material p lu s any
potential precipi tat ion accumulation . Secondary containment is required for all co nt a in ers 55-
gall ons and greater.
Incompatib le 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.
Ignitab l e 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 ignitabl e or reactive waste. Examples of ignitable wastes
are: paint wastes, certain degreasers, thinners and solvents (petroleum distillates), epoxy resins,
and adhesives.
Stormwater: It m ay b e necessary to drain accumulated stormwater from within the secondary
co ntainment areas that co ntain the fuel storage tanks. If the stormwater h as b een contaminated,
absorbent pads or booms will be used to remove floating petroleum products . A lt er the
contamination h as been removed, the stormwater will be left to evaporate, if possible, otherwise
it will be disposed of in an appropriate manner. Prior to disposal, the CGR Representative will
ch ec k for sheen or other ev idenc e of contamination .
3.3.2 Label ing Requirements
The Contractor will comp ly with the following labeling req uirements for any on-site co nt a in er
(including tanks) used to store accumulated hazardous was t es. The contain ers 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
• th e words "Hazardous Waste" and warning words indicating the particular hazards of the
waste, such as "flammable", "corrosive", or "reactive."
3.4 DISPOSAL OF HAZARDOUS WASTES
The 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 . The
Contractor will det erm ine details on the proper hand li ng and disposal of hazardous waste, and
will assign responsibility to specific individuals prior to construction of the project.
All contaminat ed articles and soi ls recovered during a re lease event shall be properly handled
and stored in DOT approved contai n ers. All wastes generated as a result of sp ill response
activit i es shall be analyze d to det ermin e if hazardous , unless knowl edg e of contaminants is
app li ed to classify these wastes as non -hazardous. Wastes determined to be h azardous shall b e
properly labeled , profiled, and manifested to an authori ze d hazardous waste , treatment , and

disposal facility . Hazardous wastes will b e stor ed in a secured location as discussed in Sec tion
3.3.1.
Any Contractor (generator) producing more that 100 kilograms per month of hazardous was te
must app l y for an EPA Identification Number. The 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.
3.5 INSPECTION AND RECORDKEEPING
The Contractor will inspect all storage facilities on a regular basis, but not less than weekly. The
Hazardous Materials Inspection Form in Appendix B will be used to record the condition of the
facility. In addition to the weekly inspection, the 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 mat eria l inspection log;
• transportation do cuments;
• bills of lading;
• manife sts;
• shipping papers;
• training records ;
• release report forms; and
• spi ll hi story .
The CGR Representative will monitor, inspect, document, and report on the Contractor's
compliance with all hazardous materials and hazardous waste management practices.
4.0 SPILL PREVENTION PRACTICES
The Contractor shall take the following precautions to ensure that a release of oil and hazardous
materials is prevented or contained.
4.1 STORAGE
Containers and tanks used for fuel and material storage will be stored and labeled as discussed in
Section 3.1 .
5
•
•
•
4.2 EMERGENCY AND PERSONAL PROTECTIVE EQU IPMENT
The following equipment wi ll b e maintain ed on-site with eac h crew usin g h eavy equipm ent 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/materials, and
• communications equipment.
4.3 FUELING AND MAINTENANCE
Construction vehicles and equipment wi ll be fueled and maintained in upland areas at least 100
feet from waterbodies. F u elin g will not occur within 20 0 feet of private we lls or 40 0 feet of
municipal wells . Wh en selecting fuelin g areas, co nsideration will b e giv en to slopes and other
to pographic conditions. Fue lin g locations will ge n erally be flat to minimi ze th e chance of spilled
substance reaching a waterbody. E very effort wi ll b e mad e to minimi ze th e threat of a fuel spill
during fueling and servicing .
Co nstruction e quipm ent requiring maintenanc e which might result in th e draining or leakin g of
fluids will be serviced only after a 12 mil polyethylene lin er has been installed between the
eq uipment and the soil. This liner must be p laced in such a manner that all fluid is contained .
A ll service vehicles used to transport lubri cants and fuel must be equipped with an emergency
response kit. At a minimum, this kit must include polyethylene sheeting, absorbent mats, a
bucket or p lastic pan to catch fuel, personal protective equipment, and a minimum of 20 pounds
of suitable absorbent material to handle potential spills. Each service vehicle shall have a
sufficient number of shovels, brooms, polyethylene sheeting, and fire protection equipment to
control a moderate -s ized spill.
4.4 NEAR WATERBODIES
If stationary equipment (i.e., pumps, generators, etc.) cannot be located at least 100 feet from
waterbodies because of topographic 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.
In areas where construction activity will cross a flowing waterbody, absorbent booms will be
placed on th e water surface downstream of the cons tru ction zone, prior to cons tru ction . An
emergenc y respons e kit will b e r equired on -s ite during clearing , grading, ti e-in , and cleanup
activities within 100 feet of a waterbody. The emergency respons e kit will includ e oil socks ,
boons, and pillows , polyethylene sheeting, absorbent mats, a bucket or plastic pan to catch fu el,
6
•
•
•
and a minimum of 2 0 pounds of suitab le absorbent material to handl e potential spills.
A ll equipment , vehicles , p ump s, hos es, and generators will be checked for leaks on a daily basis.
Leaks or drips wi ll b e repaired immediately.
5.0 EMERGENCY RESPONSE PROCEDURES
This section provides a generic description of emergency response procedures to be performed to
address petroleum and hazardous substance re leases d uring construction, operation, and
maintenance of the Porcupine Loop. Each response will vary depending on the nature and extent
of the incident; however, general protocols outlined below will be followed.
5.1 RESPONSIBILITIES
Th e Contractor is responsible for:
• Designating an emergency coordinator and two alternate emergency coordinators;
• Training personnel on contents and requirements of Spi ll Plan;
• Routine ly insp ectin g and maintaining eq uipm en t to prevent accidental leaks and spills;
• C leaning-up and addressing all spills which occur as a result of th e ir operations;
• Immediately notifying the CGR Representative of any spills; and
• Documenting spills in a daily log.
CGR is responsible for:
• Notifying appropriate agencies ofre leases in excess of RQs, including follow-up notification;
and
• Providing supporting personnel and equipment to address RQ re leases.
5.2 RESPONSE MEASURES
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;
• iso late and stop the spill and begin clean up of the spill, if safe to do so;
• notify appropriate personnel and in iti ate reporting actions; and
• initiate evac uati on of the area if necessary.
Persons should only attempt to clean up or co ntrol a spill if they h ave received proper
training . Untr ain ed individuals will immediately notify the Contractor's primary or alternate
emergency coord in ators .
If there is a spill of an unknown s ubst ance and its identity cannot be determined by observing
7
•
•
•
obvious clues (i .e. labe ls on containers , or observing an obvious sources (e .g. hydrauli c lin es,
fuel tanks , etc .), it would not be considered safe for the average p erson to con tain the spi ll. Any
spi ll of an unknown sub stan ce sho uld b e treated as a hazard and should b e approached , co ntain ed
and samp led by train ed em ergency respo nse p ers onn e l. General co nstruction perso nn e l should b e
instructed to con tain and c leanu p sp ills of only those s ub stances the y can safely identify and that
can be safe ly approac h ed (from upwind and upgradient) and handl ed, after identifying the
materials from a safe distance and location .
In general , expert adv ice wi ll be sought to properly cleanup major spi ll s (defined as any spill
over the reportable quantity for that substance). For spills on land, berms will be constructed to
contain the sp ill ed material and prevent migration of hazardous materials or petroleum products
toward waterways . Dry materials will not be cleaned up with water or burned. Contaminated
soils will be co ll ected using appropriate machinery, stored in suitable containers, and properly
disposed of in designated areas off-site.
A ft er contaminated soi l is recovered, all machinery utilized will be decontaminated, and
recov ere d soi l will b e treated as used oil if co ntaminat ed with petroleum products or hazardous
waste if co ntaminated with hazardous waste . Co nt aminated cleanup materials (ab sorbent pads,
etc.) and vegetation will be disposed of in a similar manner.
If spi ll ed materials reach water, booms and skimmers will be used to contain and remove
contaminants. Oth er actions will be taken as necessary to clean up contaminated waters .
Co ntaminated soil and materials will be stored and dispos ed of in accordance with Sections 3.3
and 3.4 .
5.3 NOTIFICATION AND DOCUMENTAT ION
Notification and documentation procedures for all spills that occur during project construction,
operation, or maintenance will conform to applicable federal , state, and local laws . Adherence to
such procedures will be the top priority after 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.
5.3.1 Reporting Criteria
The Contractor will report to the CGR Representative all hazardous substance releases regardless
of size and petroleum product spills w hi ch threaten or enter any waterbody or that are over 1
gallon in size. Verbal reports are required immediately following a major sp ill when doing so
wou ld not delay clean up or administration of urgent medical care . Any re lease of hazardous
material over the applicabl e reportable quantities (provided by th e C ontractor on th e Hazardo u s
Material Inventory Fonn) must b e rep ort ed imm edi ate ly to the National Res pons e Cen ter (NRC ),
th e BLM, the C olorado Department of P ubli c Health and Environment (CDPHE) and local
authorities. Any spi ll of petroleum product 55 gallon s or greater or any spill that enters or may
enter a Co lorado waterbody must be repo11ed to the CDPHE immediately and followed -up with
written communication within 5 days . Any spi ll greater than 1 ga ll on or any sp ill that enters or
8
•
•
•
may en ter a waterbody on BLM-land s wi ll be reported to th e BLM.
5.3.2 Notification
Notification will begin as soon as possible after discovery of a release. The individual who
discovers the sp ill will contact a CGR Represen tative. If the CGR Represen tative determines
that the spill meets the criteria for immedi ate verbal notification of government agencies and/or
determines that the spill may threaten human health or the environment, CGR's Project Manager
will make the required agency notifications as described below. 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 5.3.2.1 for standard
information that will be requested by agencies. An Emergency Contact List is provided in
Appendix C.
The following mandatory verbal notifications will be made by CGR's Project Manager:
• 911 -if an emergency
• BLM, G lenwood Springs Fire D ispatch-(970) 257-48 00-if an emergency
• National Response Center-(800) 4 24 -8802-for RQs
• Co lorado Department of Health and Environment-(877) 5 18 -5 608 emergency;
(303) 692 -35 00 non -e mergency-for RQs and any sp ill that enters or may enter a waterbody
• Garfi eld Co unty Local Emergen cy Planning Committee-(970) 945 -9151 -for RQs
• BLM, Glenwood Springs Field Office-(970) 947 -28 00-fo r any spi ll s over 1 gallon or
sp ill s that en ter or may en ter a waterbody on BLM-land
5.3.2.1 Agency Notification
The CGR Representative will provide th e following information when notifying a regu latory
agency:
• 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
