PROJECT INFORMATION AND STAFF COMMENTS
REQUEST: Special Use Permit for "Storage, Processing, and Material
Handling for an Amine Facility
OWNER/APPLICANT: Hyrup lnvestments LLLP.
OPERATOR: Noble Energy
LOCATION: Approximately eight miles southwest of Parachute, Colorado
SITE INFO: 480 acres
ACCESS: CR 306
WATER: No proposal for water
SEWER: No sewer service is proposed
EXISTING ZONING: ARRD (Agricultural Residential Rural Density)
1. BACKGROUND
The BuiHing and Planning Department is in receipt of a Special Use Permit
(SUP) application for "Storage, Processing, and Material Handling of Natural
Resource" for an Amine Facility on a 5.39 acre project site that is part of a 480
acre parcel, leased by Noble Energy. The property is located approximately eight
miles southwest of Parachute, Colorado, the NW % of Section 12, T 8 South, R
96 West. The proposal is to add the amine facillty to an existing compressor
station that is connected to an 8" pipe that is 1.5 miles in length. The applicant
has submitted a Colorado Air Permit Appllcation for a compressor and
associated equipment. The actual permit is not submitted with this application. It
is unclear if the disturbance of land will be great enough to require the applicant
submit a Storm Water Management Plan. lf approved, the applicant shall submit
all required Federal and State Permits or Plans prior to issuance of this Special
Use Permit.
2. PROPOSAL
Hyrup Energy is proposing an amine facility that will tie into an existing
compressor station to treat the natural gas by stripping off carbon dioxide that is
commonly found as a byproduct of natural gas. The carbon dioxide will be
removed from the gas using an amine based process. The carbon dioxide acid
gas will be vented in smal! amounts into the atmosphere.
3. GENERAL REQUIREMENTS FOR ALL SPECIAL USE PERMITS
55.03 Conditiona! and Special Uses (Zoning Resolution of 1978, as
amended)
1. Utilities adequate to provide water and sanitation seruice based on
accepted engineering standards and approved by the Board of County
Commissioners shall either be in place or shall be constructed in
conjunction with the proposed use.
Staff Gomments: No permanent office or manned facility is proposed. Once
construction is complete, the station will not require water or sewer service. The
system will be remotely monitored by Nobel Energy.
2. Sfreef improvements adequate to accommodate traffic volume generated
by the proposed use and to provide safe, convenient access to the use
shall either be in place or shall be constructed in conjunction with the
proposed use.
Staff Commenb: Garfield County Road and Bridge Department has issued an
access permit for this property. During construction, traffic on CR 306 will
increase. After completion of the project, the site will be remotely monitored and
traffic should be minimal. The applicant has not stated what the traffic counts to
and from the site during and after construction will be. Staff is requesting the
applicant submit additional information to adequately address this issue
3. Design of the proposed use is organized to minimize impact on and from
adjacent uses of land through installation of screen fences or landscape
mateials on the peiphery of the lot and by location of intensively utilized
areas, access points, lighting and signs in such a manner as fo protect
e sta b I i shed n e ig h borhood ch a racte r.
Staff Gomments: The proposed facility is an addition to an existing compressor.
This site is fenced and secure from trespass. All fences and gates have been
painted as well as all existing tanks have been painted a beige color in an
attempt to blend in the area. It is suggested that any new equipment should be
painted a similar color. lt is unclear to staff if any other fencing or landscape
materials will be needed as to be compatible with existing uses and not detract
from the neighborhood character.
55.03.07 Industrial Operations
(11 The applicant for a permit for industrial operations shall prepare and submit to
the Planning Director ten (10) copr'es of an impact statement on the proposed
use descnbing its location, scope, design and construction schedule, including an
explanation of its operational charactensfics. One (l) copy of the impact
statement shall be filed with the County Commissioners by the Planning Director.
The impact statement shalladdress the following:
(A) Existing lavvful use of water through depletion or pollution of sufface
rttn-off, stream flow or ground water.
Staff Comments: The applicant has not submitted any plans as to how storm
water runoff will be contained. lf applicable, the applicant will need to submit a
copy of the Storm Water Management Plan that was submitted to the State
(DCPHE) or show how depletion or pollution of surface run-off, stream flow or
groundwater will be mitigated.
(B) lmpacfs on adjacent land from the generation of vapor, dust, smoke,
noise, glare or vibration, or other emanations.
Staff Gomments: The applicant has not directly addressed this issue. lt is
unclear to staff how this site will impact adjacent land from the above mentioned
impacts. Any exhausted air shall meet all State and Federal guidelines.
(C) lmpacts on wildlife and domestic animals through the creation
hazardous attractions, alteration of existing native vegetation, blockade
migration routes, use pattems or other disruptions.
Staff Comments: The proposed site has an existing fence that the applicant
states will protect wildlife. No wildlife migration routes have been identified at this
site. lt appears the amine facility will not create larger areas that will impact
wildlife or domestic animals more than the fenced compressor facility.
(D) Affirmatively show the impacts of truck and automobile traffic to and
from such uses and their impacfs fo areas in the County.
Staff Comments: During the construction phase, vehicles and equipment will be
parked on the facility site and will not be allowed to block or hinder normal traffic.
Certified flaggers will be utilized to insure safety as part of the Traffic Control
Plan. Once construction is complete the applicant has stated that traffic will
minimal. No estimated traffic counts have been submitted with this application. lt
is unclear to staff what the proposed impact will be.
(E) That sufficient distances sha// separate such use from abutting
propefty which might otherwise be damaged by operations of the proposed
use(s).
Staff Gomments: The applicant has stated the site is near a County road and
within sight distance of a local residence. Staff has been given no more
information as to the separation of this use to abutting uses and whether it wi!!
negatively affect near by properties.
(F) Mitigation measures proposed for all of the foregoing impacts identified
and for the standards identified in Section 5.03.08 of this Resolution.
Staff Comments: The applicant has stated there is a fence around the entire
perimeter of the site that will provide safety and security.
(2) Permits may be granted for those uses with provisions that provide adequate
mitigation for the following:
(A) A plan for site rehabilitation must be approved by the County
Commissioners before a permit for conditional or special use wittbe issued.
Staff Gomments: The applicant is proposing the following rehabilitation
measures:
of
of
1. Removal of all surface equipment.
2. Restoration and re-contouring of grade to approximate original condition.
3. Replacement of stockpiled topsoil.
4. Re-vegetation of the site.
5. Compliance with all prevailing COGCC and Garfield County conditions
governing final reclamation.
The applicant has not submitted a weed inventory or a weed management plan
for the site. The site has been cleared and is currently in use as natural gas
compressor facility. The applicant has stated that no other soil will be disturbed
by the amine facility. A re-vegetation bond shall be required prior to issuance of
the Special Use Permit in an amount set forth by the Garfield County Vegetation
Department.
(B)The County Commissioners may require secuity before a permit for
special or conditional use is r'ssue4 if required. The applicant shall fumish
evidence of a bank commitment of credit, bond, certified check or other secuity
deemed acceptable by the County Commissioners in the amount calculated by
the County Commissioners to secure the execution of the site rehabilitation plan
in workmanlike manner and in accordance with the specifications and
construction schedule established or approved by the County Commissioners.
Such commitments, bonds or check shall be payable to and held by the County
Commissioners.
Staff Gomments: The applicant has submitted a "Blanket Bond" in the amount
of $25,000.
(C) lmpacfs sef forth in the impact statement and compliance with the
standards contained in Section 5.03.08 of this Resolution. (A. 93- 06 1)

RE: Review of Special Use Permit for Hyrup Amine Facility
Dear Richard:
This office has performed a review of the documents provided for the Special Use Permit
(SUP) of the Hyrup Amine Facility. Since the application appears to be adding equipment to
an existing facility, that has presumably already obtained a Special Use permit previously, the
following comments, questions, or concerns were generated:
1. In review of the permit applications information it is unclear whether the facility will be
manned. If the site is to be manned water and sanitation services will be necessary.
2. In review of the application it is unclear whether the
for proposed site disturbance, drainage patterns,
expansion of the existing facility modify these? If
measures will be necessary.

Site Inspection and Survey
A site inspection conducted by WestWater Engineering (WWE) occurred during a period of mild
weather on March 7,2006. The perimeter and adjoining lands were surveyed for plant
communities, listed noxious weeds, soils and wildlife.
Amount of Infested Land Needing Treatment
There are no listed noxious weeds on the Hyrup Amine Facility as of March 7,2006. There are
nearby areas with temporary and long-term soil and vegetation removal and disturbance. The
potential for noxious weeds is considered to be elevated due to the level of soil disturbing
activities in the immediate vicinity of the Hyrup Amine Facility.
Targeted Noxious Weeds and Control Methods
Table I lists Garfield County Noxious Weed Species for which careful and watchful monitoring
should be conducted and control initiated if observed. This information is included to facilitate
weed monitoring and control by Nobel Energy field staff.

+*A - Annual, B - biennial, P -perennial
Three species found on the State of Colorado'oC" list at 8CCRI203-19, but not Garfield County,
are found on site. Cheatgrass (Bromus tectorun't, BRTE), is common on margins (Photo 1) and
within disturbed areas for the compressor station and pipe and surplus materials storage yard
(Photo 2). As is common in the area, some pasture land and the pinyon pine-Utah juniper plant
community nearby also harbor cheatgrass. Other state listed species found on site are Russian
thistle (Salsola tragus, SATRI2) and a smallamount of field bindweed (Convolvulus atnensis,
coAR4).
Due to the intensive industrialnature of the site, it is recommended the 5.39 acre site be bare
ground treated with herbicides within the perimeter fence. The presence of production
equipment precludes any revegetation potential with the possible exception of areas around the
boundary along the access road.
There are hundreds of acres of mixed surface ownership land in the vicinity infested with
cheatgrass. Due to ownership and biology of cheatgrass it is not practical or recommended by
WWE for treatment to be extended to this species within the temporary disturbance area of this
project other than indirectly through revegetation of temporary disturbance. The exception
would be if the treatment were part of a larger, coordinated integrated vegetation and noxious
weed plan on adjoining lands between all affected owners.
The following tables summarize the most effective treatment strategies for noxious weeds,
depending upon their growth habits. This is particularly applicable to areas outside the perimeter
fence. These areas should not be bare ground treated. Table 2 includes annuals and biennials,
and Table 3 show strategies for perennial weeds.

Recommendations
Revegetation. There is little space for re-vegetation particularly if the temporary footprint is
rninimized. Where possible, we recommend that disturbed areas be re-seeded immediately with
the following seed rnix which is fonnulated in consideration of soils and plant communities:
Seed should be applied imrnediately upon completion of construction by broadcasting at an
application rate of approxirnately 47-seeds/square foot onto a roughened surface followed by
harrowing. Re-seeding may be required if future monitoring indicates lack of adequate
germination. Fall seeding (after October l and prior to ground frost) are generally much more
successful than other periods ofthe year.
Table 3. Treatment Strategies for Perennials
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.
2. Herbicide treatment at bud to bloom stage or in the fall. 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. Using two or more herbicides with different modes of action is most effective with
particularly difficult perennials. 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 the fallwill 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
may be reduced, however. 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;
lherefore, it is imperative to know the species and its biology.

Monitoring. Monitoring for targeted weeds and re-seeding success should be performed on a
weekly basis beginning at spring green-up and continuing through the growing season.
Monitoring by qualified personnel should be conducted using Table 5 as a general guide to key
plant growth periods and best control periods.
Mechanical
Observed weeds, particularly rosettes, should be controlled when possible and practical first by
mechanical means, primarily by hand grubbing or pulling.
Control of listed species in nearby areas is recommended to reduce the risk and rate of infestation
in the affected rightof-way.
Chemical
WestWater recommends bare ground herbicide treatment for the entire site. This is to prevent
storage areas and perimeter land frorn becoming a source of contamination for nearby
disturbance and due to the highly developed nature of the facility.
Spot treating may become necessary and should include areas immediately adjacent to the site on
adjoining lands.
Chernicals typically used include synthetic auxin growth regulators (e.g.,2,4D; picloram,
dicamba, and triclopyr), EPSP synthase inhibitors (e.g., glyphosate) or a mix of these. For
Canada thistle, Russian knapweed and other difficult perennials, a mix of two different modes of
actions performs best. In all cases, the certified applicator shall deem which chemical(s) and at
what concentration(s) shall be used at the time of application. It is anticipated the
aforementioned classes of chemicals will be first choice of most Certified Applicators or
Qualified Supervisors.
It is recommended a private contractor be engaged to conduct the weed control and monitoring,
or that a company representative with weed identification capabilities and pesticide application
knowledge (preferably with a certified applicator's license) be assigned this function.
Additional Information: Table 5 is a guide to timing of key biological processes and the best
time for control of the subject species on an annual basis.

Discussion
The site is adjacent to an open pasture at the junction of three roads including County Road 306.
The pinyon pine-Utah juniper woodlands on steeper, rugged slopes to the northeast provide
escape cover for mule deer and many of the above listed species. Within the overall landscape,
this iite is of low value to most wildlife species listed. Occasionally many species could wander
through or pass over the site. Grazing by mule deer or elk on perimeter vegetation is likely.
Sorne grazing by cattle was evident at the time of inspection. No wildlife use was observed on
the site and none is expected.
Although many well pads and small and large ranches are mixed throughout the local landscape,
wildlife is generally abundant in the area. During times of peak human activity wildlife will be
displaced from the immediate vicinity. Due to the nature of work at the site it has been
recommended the site be bare ground treated to reduce the potential for accidental ignition of
senescent weedy vegetation.
Wildlife Mitigation and Management Recommendations
Improve undisturbed sagebrush shrublands. Greater thang5oh of the site is developed and it
is a relatively small site compared to the surrounding landscape. Some methods to compensate
for the loss of wildlife habitat from development of the site is to improve nearby sagebrush
communities. Methods including mechanicalremovalof invasive pinyon pine or Utah juniper,
chopping or mowing a portion of the older, more senescent sagebrush, removing all or a portion
of domestic livestock grazing, and fertilization could be implemented. Fertilization of 125 lbs
available nitrogen/acre has been shown to have a positive affect for sagebrush plant community-
dependent wildlife for 5-7 years after fertilization. Mechanicalremovalof invasive woodlands
into sagebrush plant communities can have a positive impact for many years.
Minimize footprint of temporary disturbance. Reduce to the minimum level possible all soil
disturbing activities. Park construction vehicles on previously disturbed lands during
construction to further reduce temporary disturbance.
Re-seeding. The small temporary disturbances on site have been recommended to be re-seeded
with native grasses and shrubs as well as introduced, short-lived but highly wildlife-desirable,
non-bloating legumes. Due to the small area of such seeding, it is unlikely to provide significant
benefit for wildlife use. However, reducing the potential for noxious weeds is a positive measure
for wildlife. These measures are described in the Integrated Vegetation and Noxious Weed
Management Plan for this site.
Fence Maintenance. The perimeter fence should be rnaintained in a way to reduce the potential
for mule deer entrapment from entangling in the fence. Any unnecessary fence should be
removed to reduce potential wildlife entrapment in severe winters.
Surface Water or Fluid Ponds. Any surface pond containing fluids potentially detrimental for
wildlife should be protected by flagging or netting sufficient to deter use by birds or other
wildlife.
