Subject: Amendment to Development Plan Submission for Chevron's Piceance Valley
Pipeline and 36-1 Compressor Station
Dear Mr. Jarman:
Pursuant to section 9.07.13 — Amendments to a Development Plan, of Garfield County
Building and Planning regulations Chevron U.S.A., Inc. (Chevron) would like to amend
the development plan for the Chevron Piceance Valley Pipeline Project.
The original 8" gas pipeline route has changed slightly in certain areas. The overall
narrative description has been updated to reflect the proposed route and "Plan and
Profile" plats have been attached showing the realignment of the proposed pipeline
route in reference to the original planned route. A supplemental application has been
submitted to comply with the Army Corps of Engineers Nationwide Permit application
conditions for 1 additional drainage crossing of Clear Creek. A copy of the application is
attached. In addition, an updated Integrated Vegetation and Noxious Weed
Management Plan for the entire length of the realignment has been prepared and is
attached.
In addition to the pipeline realignment Chevron also requests clearance to add a second
compressor and associated scrubbers to the compressor station on well pad #598-36-1
located approximately 17 miles northwest of De Beque. An updated narrative for the
new compressor and associated scrubbers is attached.
Please contact me at 970.263.7800 with any questions that you may have regarding
this permit. Thank you for your time and consideration.
Sincerely,

1) A vicinity map indicating the section, township and range of the site, and its relation to
surrounding public roads and municipal boundaries.
The proposed project site includes portions of Section 36 Township 5 South, Range 98
West, Garfield County, and portions of Sections 4, 9, 10, 15, 22, 27 and 28 Township 6
South, Range 98 West, Garfield County. The pipeline right-of-way begins on Chevron
property in the SE1/4SW1/4 of Section 28 at the 698-28-1 well pad. The pipeline then
runs east for approximately two miles, crossing County Road 211 in the south half of
Section 27. After crossing the road and continuing east, the pipeline enters property
owned by Shell Frontier. Once on the Shell property, the pipeline continues east,
crossing Clear Creek, then turning to run north, paralleling Clear Creek through Section
22, where it crosses back over onto Chevron owned property before crossing County
Road 211 again in the south half of Section 15. The pipeline continues heading north
northwest through Sections 15 and 9, then crosses Clear Creek again in the south half
of Section 4. The pipeline continues north northwest across Section 4 where it crosses
Clear Creek one final time before entering into Section 36, ending at the 598-36-1 well
pad in the SE1/4SW1/4 of Section 36.
Plan and Profile maps of the pipeline realignment are attached.
The proposed project will involve approximately 39 acres of resource land primarily
located on Chevron land and traversing a small portion of land owned by Shell Frontier,
located approximately 17 miles north of De Beque in Garfield County, Colorado.
2) Project Overview: a description of the project including the length of the pipeline,
diameter of the pipeline, pipeline commodity, and the general description of the pipeline
route.
Chevron has proposed the construction of an 8 -inch natural gas pipeline beginning in the
SE1/4SW1/4 of Section 28 Township 6 South, Range 98 West of the Sixth Principal
Meridian, Garfield County, Colorado, running east for approximately two miles across
the S1/2 of Section 28 and the S1/2 of Section 27, then turning north and running for
approximately one and one-half miles north into the S1/2 of Section 22, then turning
slightly to run north northwest for approximately one-quarter of a mile before turning
north and running for approximately 700 feet, then turning to the northwest for
approximately 175 feet, then turning slightly back to the north and generally paralleling
Garfield County Road 211 and Chevron access road for two and one-quarter miles
through Sections 15, 10, 9 and 4, then ending at the proposed 36-1 compressor station
in the SE1/4SW1/4 of Section 36 Township 5 South, Range 98 West of the Sixth
Principal Meridian, Garfield County, Colorado.
Plan and Profile maps of the pipeline realignment are attached.
The total length of the pipeline is six and one-quarter miles. The pipeline right-of-way will
be less than fifty feet wide and the entire right-of-way will be reclaimed upon completion.
The compressor will be installed on an already existing compressor station identified as
598-36-1. The 36-1 site was originally permitted through the Colorado Oil and Gas
Conservation Commission as a well site in 2005. Drilling was never initiated on the site
and it became a de facto gathering site for Chevron's existing wells in Skinner Ridge to
the west, Tom Creek to the northeast, and Deer Park Gulch to the east.
The additional facilities that will be placed on-site in affiliation with the compressor
project include:
• One compressor skid, 12' x 37' x 12', with attached cooler
• In addition, the skid will contain one suction scrubber and an interstage
scrubber, 20" x 8'

Chevron Clear Creek 8 Inch Pipeline
Integrated Vegetation and Noxious Weed Management Plan
May 2007
Introduction
On May 10 and 11, 2007, a field inspection of the proposed 8 -inch pipeline realignment was
conducted by WestWater Engineering (W WE) biologists. The proposed route realignment more
nearly follows Clear Creek Road than the previous route which was inspected in November
2006. The inspection identified appropriate topics for inclusion in an integrated vegetation and
noxious weed management plan required by Garfield County Regulation 9.07.04 (13) (BOCC
2006). Factors considered include soil type and texture, existing land management, absence or
presence of listed noxious weeds and likely potential natural vegetation community.
Landscape Setting
Chevron Clear Creek 8 Inch Pipeline Realignment is on the first terrace above Clear Creek and
generally follows the creek and road in a southeasterly direction before turning west and
climbing the slopes of Mt. Blaine. It tends to stay on drier slopes more than the previous
alignment. Clear Creek is lined with watercress (Nasturtium officinale), with a heavy riparian
deciduous shrub and woodland overstory comprised of mountain boxelder (Acer negundo), and
introduced and naturalized New Mexico locust (Robinia neomexicana). The New Mexico locust
has crowded out most of the native shrubs one would expect such as skunkbush sumac (Rhus
trilobata) and willows (Salix spp.).
Terrain is gently sloping to moderately steep. Soils on the pipeline route are cumulic
haploborolls in the meadow -forming swales and fans along the creek; Happle, very channery
sandy loam on moderately steep, brushy toe slopes, foot slopes, fans; and Biedsaw-Sunup,
gravelly loams on the steep slopes where the route turns westerly to the southern terminus on the
slopes of Mount Blaine. The cumulic haploborolls are deep and generally have textures of
gravelly and channery sandy loam to loamy sand. The Happle soils are variable but are mostly
deep with very channery sandy loam textures. The Biedsaw-Sunup soils are deep to shallow and
range from gravelly loam to clay loam (NRCS 2006a).
Vegetation frequently encountered during the survey included: western wheatgrass (Pascopyrum
smithii), downy brome (Anisantha tectorum), Wyoming big sagebrush (Artemsia tridentata
wyomingensis), basin big sagebrush (Artemesia tridentata tridentata), greasewood (Sarcobatus
vermiculatus), shadscale (Atriplex confertifolia), New Mexico locust (Robinia neomexican),
mountain boxelder (Acer negundo), Utah juniper (Juniperus osteosperma), pinyon pine, (Pinus
edulis), Osterhout's penstemon (Penstemon osterhoutii,), tumble mustard (Sisymbrium
altissimum), horehound (Marrubium vulgare, along roadside ditches), burr buttercup
(Ranunculus testiculatus), flixweed (Descurainia Sophia), rabbitbrush (Chrysothamnus spp.),
bulbous bluegrass (Poa bulbosa), pricklypear cactus (Opuntia spp.), purple mustard ( Chorispora
tenella) and the native wavy -leaf thistle (Cirsium undulatum). See Table 1 for additional
(weedy) plants.

Mount Blaine to the southern terminus has native vegetation dominated by Utah juniper
(Juniperis utahensis), pinyon pine (Pinus edulis), western wheatgrass, bottlebrush squirreltail,
and Wyoming big sagebrush.
Current Amount of Infested Land Needing Treatment
More than half the route for the pipeline is exposed to or infested with Garfield County and State
of Colorado (8 CCR 1203-19) listed noxious weed species (Figure 2, page 14). This is
particularly true near Clear Creek along the edge of the deciduous riparian vegetation and
meadows and where the pipeline realignment nears Gibler Ditch (See Photos 1 through 3). All
noxious weeds observed were noted due to the adverse impact these species may have on
reclamation. With a few exceptions, only Garfield County listed weeds were mapped. Some
species not listed in Garfield County are listed in adjacent jurisdictions, e.g., common mullein.
Species in bold type in Table 1 are Garfield County listed noxious weeds. Those in regular type
are listed by the State of Colorado as noted.
Photo 2. Typical riparian vegetation
Photo 3. Shrubland as pipeline turns west
Only areas near the pipeline realignment route were surveyed but it can be assumed that the
banks of Clear Creek and Gibler Ditch, for most of their length, are weedy.
The attached appendix contains Guidance Positioning Survey (GPS) coordinates of some
concentrated areas of noxious weeds.
Recommended Treatment
It is important to know whether the target is annual, biennial, or perennial to select strategies that
effectively control and hopefully eliminate the target. Treatment strategies are different
depending on plant type and are summarized in Tables 2 and 3. Herbicides should not
necessarily always be the first treatment of choice when other methods can be effectively
employed.
WestWater Engineering
Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 3 of 13
Table 2. Treatment Strategies for Annual and Biennial Noxious Weeds
Target: Prevent Seed Production
1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds
develop, cut and bag seed heads.
2. Chop roots with a spade below soil level.
3. Treat with herbicide in rosette or bolting stage, before flowering.
4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but
can reduce total seed production.
(Sirota 2004)
Table 3. Treatment Strategies for Perennials
Target: Deplete nutrient reserves in root system, prevent seed production
1. Allow plants to expend as much energy from root system as possible, do not treat when first
emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if
possible.
2. Herbicide treatment at bud to bloom stage or in the fall (recommended, after August 15 when
natural precipitation is present). In the fall plants draw nutrients into the roots for winter
storage. Herbicides will be drawn down to the roots more efficiently at this time due to
translocation of nutrients to roots rather than leaves. If the weed patch has been present for a
long period of time, another season of seed production is not as important as getting the
herbicide into the root system. Spraying in fall (after middle August) will kill the following
year's shoots, which are being formed on the roots at this time.
3. Mowing usually is not recommended because the plants will flower anyway; seed production
should be reduced. Many studies have shown that mowing perennials and spraying the re-
growth is not as effective as spraying without mowing. Effect of mowing is species
dependent; therefore, it is imperative to know the species and its basic biology. Timing of
application must be done when biologically appropriate which is not necessarily convenient.
4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only 'A in. -
1 in. long. Clean machinery thoroughly before leaving the weed patch.
5. Hand pulling is generally not recommended for perennial species unless you know the plants
are seedlings and not established plants. Hand pulling can be effective on small patches but is
very labor intensive because it must be done repeatedly.
(Sirota 2004)
Herbicide treatment with two or more herbicide modes of action in fall (after approximately
August 15 when natural precipitation is present) is the best method to control difficult perennials.
Following any non-selective herbicide treatment (e.g., glyphosate), the entire treated portion
should be replanted with a mix of grasses recommended in this plan. The seed mix of grasses
does not include forbs or shrubs due to the presence of field bindweed. Shrubs and native forbs
are adversely affected by herbicides much as the weeds are affected. Shrub, forb and tree
components of the vegetation community can be added after control of undesirable species has
been attained. For example, in irrigated meadows, re -planting of the entire meadow with a mix
WestWater Engineering
Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 4 of 13
of grasses and non -bloating legumes such as sainfoin, Onobrychis viciaefolia, followed by rest
from grazing is recommended.
Best Management Practices
The following practices should be adopted for any construction project to reduce the costs of
noxious weed control. The practices include:
• top soil, where present, should be segregated from deeper soils and replaced as top soil
on the final grade, a process known as live topsoil handling,
• in alt cases temporary disturbance should be kept to an absolute minimum,
• equipment and materials handling should be done on established sites such as the
northern point of origin to reduce area and extent of soil compaction,
• disturbances should be immediately replanted with the recommended mix in the re -
vegetation section.
• for weeds WWE recommends moving the pipeline laterally to keep as much of the route
in the meadows and out of the shrubs as possible. It is far easier to manage meadow
vegetation than to reestablish shrubs and control weeds in shrubs.
• topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses if stored
longer than one growing season,
• prior to delivery to the site, equipment should be cleaned of soils remaining from
previous construction sites which may be contaminated with noxious weecs,
• equipment and materials handling should be done on established sites to reduce area and
extent of soil compaction,
• if working in contaminated sites, equipment should be cleaned of potentially seed -bearing
vegetative debris prior to moving to uncontaminated terrain,
In areas with slope greater than 3%, imprinting of the seed bed is recommended. Imprinting can
be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro -
seeding or mulching, imprinting should be done prior to seeding unless the mulch is to be
crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as
part of the harrowing. Furrowing can be done by several methods, the most simple of which is to
drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting
methods include deep hand raking and harrowing, always perpendicular to the direction of slope.
Herbicides:
Difficult species such as hoary cress respond better to application of a combination of two or
more chemical modes of action (biological reason for plant death) rather than one. It has also
been found that use of two different groups of chemicals in the same mode of action can increase
effectiveness on difficult species, e.g., phenoxys and benzoic acids or carboxylic acids and
benzoic acids in a mix. Some come commercially pre -mixed, e.g., Crossbow and Super Weed -
be -Gone Max, which are available over the counter. Some of the most effective herbicides are
restricted use and available only for licensed applicators.
Professionals or landowners using herbicides must use the concentration specified. Herbicides
generally do not work better at higher concentrations. Most herbicide failures observed by
WestWater Engineering
Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 5 of 13
WWE are related to incomplete control caused by high concentrations killing top growth before
the active ingredient can be transported to the roots through the nutrient relocation process.
Most herbicide applications should use a surfactant as directed on the herbicide label or other
adjuvants as called for on the herbicide label.
Houndstongue was often found growing in the shade of larger shrubs. Herbicide applications will
have to be administered carefully to avoid harming the overstory vegetation. The noxious weeds
most commonly found along Clear Creek and Gibler Ditch were musk thistle, houndstongue,
common burdock and saltcedar (Photos 4 through 7). Herbicides, if used, will have to be
selected for use near waterways and be very skillfully applied to avoid runoff into the nearby
drainage.

as Targe as 24 inches across
Photo 6. Common burdock rosette

Photo 7. Saltcedar (mid -ground) has not
leafed out yet. The leafy shrub is willow.
Grazing:
There is currently heavy grazing on much of the pipeline route. Observations indicate areas
currently open to cattle grazing harbor the greatest distribution, diversity and density of weeds.
WestWater Engineering
Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 6 of 13
Grazing should be controlled in a manner to enhance rather than diminish the plant community.
Certain noxious weeds are highly palatable during short stages of the life cycle to certain grazing
animals including goats, sheep, mule deer, elk, cattle and horses. Preparation and
implementation of an appropriate grazing management plan should be considered.
Photo 8. Cow covered with burdock seed heads
Noxious weeds compete with desirable vegetation. They can also have a direct effect on animals.
The Photo 8, above, was taken during the May 2007 weed survey. It shows a cow covered with
burdock seed heads and her calf (calf's muzzle is at the very left of Photo 8). Not seen clearly in
Photo 8 are the burdock seed heads on her udder, which may make it difficult to suckle for both
the calf and the cow.
Mechanical:
It is recommended senescent, seed -bearing, listed weeds on the route and adjacent to the route be
cut, bagged and disposed of in a licensed landfill. Rosettes can be cut with a shovel below the
surface of the soil on plants which are not yet dormant. Even with some seed drop, cutting and
bagging will greatly reduce seed release. Future need to do mechanical or other control methods
should be reduced after only two seasons of cutting and bagging.
Alternative Methods:
Some noxious weeds are subject to damage from beneficial insects. Included are musk and
plumeless thistle rosette weevil (Trichosirocalus horridus) and thistle defoliating beetle (Cassida
WestWater Engineering
Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 7 of 13
rubiginosa), which feeds on the foliage of Canada, musk, and plumeless thistles (Sullivan 2004).
Currently, the thistles present are not of sufficient density, in the opinion of W WE, to support
populations of insect parasites. Therefore, it is unlikely these insects would be helpful unless
explosive spread and growth occurs after the pipeline is constructed.
The bindweed mite (Aceria malherbae) is a microscopic mite imported from southern Europe as
a biological control agent for field bindweed (Hammon 2006). According to recent anecdotal
information, it may be a very effective control for bindweed on adjacent land and the pipeline
route. This mite may be useful for reducing field bindweed.
Another alternative method, particularly for downy brome infestations and poor to non-existent
topsoil in the Utah juniper woodlands on Mt. Blaine, is the application of vesicular-arbuscular
mycorrhizal fungi (V/AMF). These fungi, mostly of the genus Glomus are symbiotic with about
80% of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and
ecto-mycorrhizal fungi are associated mostly with trees and some shrubs. In symbiosis, the fungi
increase water and nutrient transfer capacity of the host root system by as much as several orders
of magnitude (Barrow and McCaslin 1995).
Over-the-counter commercial products, which are better adapted to coating seeds when reseeding
and treating roots of live seedling trees and shrubs at time of planting come in powder form and
are available from many different sources. V/AMF products should contain more than one
species of V/AMF. Some applicators, including a New Castle company, collect and grow local
accessions of V/AMF. The latter are applied to weed patches and are reputed to greatly increase
competition of native plants thereby affecting a non -chemical control of some noxious weeds.
Re -vegetation
Soil types on the property support many of the same species of native vegetation. As stated
previously, the recommended mix is limited to grasses due to the prevalence of field bindweed
and the need to use selective herbicides to spot treat for field bindweed, biennial common
burdock, bull thistle, and musk thistle. Table 4 lists recommended seed mix for area.

For the most successful results the recommended grass mixture reseeding should be done
in late autumn. The reseeding rate should be doubled for broadcast application. Preferred
seeding method is multiple seed bin rangeland drill with no soil preparation other than simple
grading to slope and waterbars. Seed should be bagged separately so each size group of seed can
be metered at the appropriate rate. Applying a quarter pound over an acre with a species such as
Canby bluegrass is difficult and may require use of wheat bran or rice hulls or some other
adjuvant to assist metering the small seeds at the appropriate rate.
Alternative seeding methods include but are not limited to:
• harrow with just enough soil moisture to create a rough surface, broadcast seed and re -
harrow, preferably at a 90 degree angle to the first harrow,
• hydro -seeding (most economical in terms of seed cost), and
• hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking.
• These are not the only means of replanting the site. However, these methods have been
observed to be effective in similar landscapes.
After desired grasses are established and control of target weed species is successful then shrubs,
forbs and trees can be planted without concern for herbicide damage. Few native forb seeds are
available commercially as cultivars. Most are collected from natural populations. Native shrubs
and forbs often do not establish well from seed, particularly when mixed with grasses. Past
experience has shown that stabilizing the soil with grasses, accomplishing weed control and then
coming back to plant live; containerized woody species in copses has been the most cost
effective method for establishing the woody species component of the plant community.

Commercial Applicator Recommendations
A certified commercial applicator is a good choice for initial control efforts. An applicator has
the full range of knowledge, skills, equipment, and experience desired when dealing with
difficult vegetation.
Common chemical and trade names may be used in this report. The use of trade names is
for clarity by the reader. Inclusion of a trade name does not imply endorsement of that
particular brand of herbicide and exclusion does not imply non -approval. Certified
commercial applicators will decide which herbicide to use and at what concentration
according to label directions. Landowners using unrestricted products must obey all label
warnings, cautions, and application concentrations. The author of this report is not
responsible for inappropriate herbicide use by readers.

Block 24 - NAMES AND ADDRESSES OF ADJOINING PROPERTY OWNERS, LESSEES, etc., WHOSE PROPERTY
ADJOINS THE PROJECT SITE. List complete names and full mailing addresses of the adjacent property owners (public
and private) lessees, etc., whose property adjoins the waterbody or aquatic site where the work is being proposed so that
they may be notified of the proposed activity (usually by public notice). If more space is needed, attach an extra sheet of
paper marked 'Block 24".
Block 25 - INFORMATION ABOUT APPROVALS OR DENIALS BY OTHER AGENCIES. You may need the approval of
other Federal, State, or Local agencies for your project. Identify any applications you have submitted and the status, if
any (approved or denied) of each application. You need not have obtained all other permits before applying for a Corps
permit.
Block 26 - SIGNATURE OF APPLICANT OR AGENT. The application must be signed by the owner or other authorized
party (agent). This signature shall be an affirmation that the party applying for the permit possesses the requisite property
rights to undertake the activity applied for (including compliance with special conditions, mitigation, etc.).
DRAWINGS AND ILLUSTRATIONS - GENERAL INFORMATION
Three types of illustrations are needed to properly depict the work to be undertaken. These illustrations or drawings are
identified as a Vicinity Map, a Plan View, or a Typical Cross -Section Map. Identify each illustration with a figure or
attachment number.
Please submit one original, or good quality copy, of all drawings on an 8.5 X 11 inch plain white paper (tracing paper or
film may be substituted). Use the fewest number of sheets necessary for your drawings or illustrations.
Each illustration should identify the project, the applicant, and the type of illustration (vicinity map, plan view, or cross-
section). While illustrations need not be professional (many small, private project illustrations are prepared by hand), they
should be clear, accurate and contain all necessary information.
