Special Use Permit for "Processing and
Material Handling ofNatural Resources" for a
Natural Gas Compressor Station
Encana Oil & Gas USA, Inc
The subject property is located at the end of
CR 215 northwest of Parachute (UNOCAL
Property)
Approximately 27,000 acres
Resource Lands (Gentle Slopes and Lower
Valley Floor)
I. DESCRIPTION OF THE PROPOSAL
The Building and Planning Department received a Special Use Permit (SUP) application for
"Processing and Material Handling of Natural Resource" for a natural gas compressor station (the
Compressor) on a 27 ,000-acre property owned by Encana Oil & Gas USA, Inc located at the end of
County Road 215 north of Parachute which is also formerly known as the old UNOCAL property
where considerable oil shale processing occurred in the 1980s. The Compressor is located just
beyond the private gate at the end of County Road 215 adjacent to a recently permitted produced
water storage facility.

More specifically, the Applicant, represented by Wagon Wheel Consulting, requests approval for a
Compressor which is presently under construction. This compressor will serve as a collector point
where gathered natural gas is sent for dehydration and compression of gas collected in the North
Parachute Ranch. Gathering systems in the area transport natural gas from wells to the proposed
Middle fork Compressor Station. Once compressed, the natural gas is delivered to a higher pressure
system and transported to a location where it is conditioned for sales.
Processing
The application indicates that natural gas producing wells require a gathering system operate at a low
enough pressure that optimizes well performance and deliverability. Without the boost in pressure
from a compressor station, most wells would not be able to produce into a high pressure system. The
wells would not flow. At the time when the natural gas is delivered to the compressor station, free
liquids including hydrocarbons and water are separated using conventional separation equipment.
This separation is critical to prevent damage to compression equipment. The hydrocarbon liquids are
measured and combined with other liquids and sold. The water is then hauled to an approved water
treatment and disposal facility.
The application describes the dehydration process where once the gas is compressed; it is then
dehydrated using a methylene glycol (TEG) dehydration system. As the gas is contacted with lean
TEG, the water is absorbed by the glycol, thus removing it from the gas. The glycol and water (rich)
solution is sent to a reboiler where the water is driven off as steam. The lean TEG is then sent back
to a contactor for a continuous removal of water from the gas stream. Once dehydrated the gas is
then delivered to a common high pressure line and sent to a facility for more conditioning. Once
conditioned, the gas is then sold and delivered to markets in the area.
Associated Pipelines
In order to send gas to and from the compressor, the Applicant intends to construct three segments of
pipeline. The first segment consists of a 1 O" pipeline (having a length of 1.2 miles) and will bring gas
from the existing gathering line network on the NPR to the compressor facility. The discharge
pipeline consists of two segments (12" in width and having a length of approximately I mile); the
first segment will leave the compressor and connect to an existing pipeline owned by Encana
purchased from American Soda and then the second segment will run from that line to the Roan Cliff
Interconnect which is an existing pipeline connection that delivers natural gas to the Rifle
Compressor Station. The total pipeline length of the three segments is approximately 2.2 miles and
ranges in width from 10" to 12".
II. BACKGROUND
As you will recall, at one time, the County did not "regulate" compressors as a stand-alone land use
Middle Fork Compressor Station
BOCC 08115105
Page3
due to a previous determination of the Colorado Oil & Gas Conservation Commission (COGCC).
However, more recently, the COGCC officially acknowledged thatlocal governments could regulate
compressors through their local zoning frameworks. As a result, Encana began construction of the
subject compressor under the COGCC' s former position which is why Staff discovered the project
"under construction" on a site visit for another project. So, technically, Encana could continue
construction without a land use permit since construction had already begun under the previous
COGCC determination. However; they wish to obtain the proper Special Use Permit for the facility.
It should be noted that proper building permits were sought through Garfield County at the correct
time for the project.
New Pipeline Regulations
As you are also aware, under the newly approved pipeline regulations this summer, this compressor
would require County review if the pipelines to which the compressor station is appurtenant to are
greater than 12" in diameter and over 2 miles in length or any width of pipeline over 5 miles in
length. However, in this case, there is 1.2 miles of a 10" pipeline and 1 mile of a 12" pipeline. As a
result, these pipeline segments and compressor would not require any review by the County.
Referral to Planning Commission
In light of the above, Staff brought the application to your attention so that you could determine if a
referral to the Planning Commission was necessary. You did not refer the application to the Planning
Commission due to 1) the limited nature of potential impacts to surrounding properties, 2) the remote
location of the property such that it is situated at the end of a dead-end county road which is used
primarily for industrial traffic serving the existing industrial uses in the area with very limited
general population traffic, and 3) the fact that the site itself will be situated in an industrial area
already characterized by intense industrial activity from the oil shale exploration I processing
activities.
III. SITE DESCRIPTION
The proposed site where the
Compressor is located is
situated on flat river basin
land that is situated at the
general confluence of the
West, East, and Middle
Forks of Parachute Creek.
The Compressor is located
on approximately 4 acres of ,
the total 27,000 acre parcel
owned by Encana. The area
where the Compressor is to
Middle Fork Compressor Station
BOCC-08115105
Page4
be located is surrotmded by steep slopes and canyons forming the general confluence of the three
creeks. Much of the area near the Compressor has been denuded by the former oil shale operations
and continues to be a location which contains staging areas for heavy machinezy, large water hauling
trucks, drilling rigs, and pipes associated with natural gas exploration. Dense mature riparian
vegetation exists along the creeks as they pass through the area.
IV. ZONING & ADJACENT USES
The subject property is zoned Resource Lands (Gentle Slopes and Lower Valley Floor). The type of
use requested falls tmder the definition of"Processing and Material Handling ofNatural Resources"
which are contemplated as special uses in the Resource Lands (Gentle Slopes and Lower Valley
Floor) zone district.
The property also now known as the North Parachute Ranch was the area where a majority of the oil
shale exploration and development occurred. The compressor is located on approximately 4 acres of
a 27,000 acre property which is surrotmded by properties also owned and utilized by the energy
industzy such as Chevron, Exxon/Mobile, Williams Production RMT, American Soda, etc.
Neighboring uses on those lands include rangeland grazing, farming, and resource extraction (natural
gas drilling).
V. AUTHORITY & APPLICABILITY
Pursuant to Section 9.03.04 of the Zoning Resolution, an application for a Special Use Permit shall
be approved or denied by the Board of Cotmty Commissioners after holding a public hearing thereon
in conformance with all provisions of the Zoning Resolution.
VI. REVIEW AGENCY AND OTHER COMMENTS
Comments have been received from the following agencies I community groups and are integrated
throughout this memorandum as applicable.
1. Town of Parachute: Posed three questions including: 1) Would the application be subject to
any road or traffic impact fees, 2) If so, are any of the funds collected dedicated to expansion
of the I-70 interchange at Parachute, and 3) Does the Cotmty review the direct impact of the
local jurisdiction? (See Exhibit E).
2. Garfield Cotmty Road and Bridge Department: Garfield Cotmty has no comments or requests
for this application. The road to the new compressor site is an existing road that meets the
Cotmty' s standards and does not foresee a major increase in traffic flow after the construction
period and the compressor is online. (See Exhibit G).
3. Garfield Cotmty Vegetation Management: See Exhibit J.
Middle Fork Compressor Station
BOCC -08115105

4. Garfield County Oil and Gas Auditor: In the "Impact Statement" section and elsewhere
where appropriate, I would recommend that the applicant indicate that they will also comply
with the COGCC's noise limits in addition to the CRS citation provided. Currently, both
sets of limits are consistent, however, there is the potential that the COGCC may revise their
noise rules and inclusion of a reference to the COGCC rules will ensure compliance with
both. (See Exhibit F).
5. Grand Valley Fire Protection District: No objections to the use. (See Exhibit I)
VII. REVIEW CRITERIA FOR SPECIAL USE PERMITS (SECTION 5:03)
Pursuant to Section 5. 03, as listed under the Zone District Regulations, special uses shall conform to
all requirements listed thereunder and elsewhere in the Zoning Resolution, as well as the following
standards:
1. Utilities adequate to provide water and sanitation service 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.
Response
The proposed Compressor is considered to be an unmanned facility. The operation of the facility
requires no water or sanitation services since it is an unmanned operation.
2. Street 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.
Response
The application states that the Compressor, once constructed, is expected to generate an average of 4
pick·up trips per day into and out of the facility. Most of this truck travel will be coming from and
going back to drilling sites on the North Parachute Ranch property on private roads constructed by
the industry or from Parachute on CR 215.
The Garfield County Road and Bridge Department has no comments or requests for this application.
The road to the Compressor site is an existing road that meets the County's standards and the County
does not foresee a major increase in traffic flow after the construction period and the Compressor is
online. No improvements to CR 215 are necessary as a result of this Compressor.
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 materials on the periphery of the lot and
by location of intensively utilized areas, access points, lighting and signs in such a manner as to
protect established neighborhood character.
Response
Middle Fork Compressor Station
BOCC -08115105
Page6
The property is located in an extremely secluded portion of the property which is practically screened
by adjacent steep topography and is located approximately 3 miles from the nearest residence. It
cannot be seen from CR 215. As noted earlier, the proposed use will have relatively limited impact to
surrounding properties. It is situated in a remote private location on the property such that it is
situated at the end of a dead-end county road which is used primarily for industrial traffic serving the
existing industrial uses in the area with very limited general population traffic. Further, the site itself
is situated in an industrial area already characterized by intense industrial activity from the oil shale
exploration I processing activities. No screening is necessary as it is already screened by steep
topography. While no lighting is proposed, any future lighting shall be directed inward and
downward towards. The Applicant plans to paint all the equipment beige in order to better blend in
with the surrounding environment.
Section 5.03.07 llndustrial Operations/
Pursuant to Section 5.03.07 of the Zoning Resolution, a permit for Industrial Operations requires the
submittal of an impact statement on the proposed use describing its location, scope, design and
construction schedule, including an explanation of its operational characteristics. The impact
statement is required to address the following:
(A) Existing lawful use of water through depletion or pollution of surface run-off, streamjlow
or ground water.
Response
The facility site has been designed to insure protection of ground water and nearby streams through
the development and implementation of a Storm Water Management Plan specific to the area which
is contained at the rear of the application. Staff notes that while this plan is specific to the
Compressor site, Encana has also submitted a larger Storm Water Management Plan for the general
area. Further, containment facilities are designed into the facility for any hazardous material stored or
used during operations. There will be no sewage or solid waste generated on the site.
(B) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or
vibration, or other emanations.
Response
Compressors produce considerable volumes of noise and vibration but whose acceptable levels are
regulated by the Colorado Revised Statutes. The application states the Compressor is initially
planned to be powered by natural gas which will not exceed the noise or vibration limits set forth by
the State of Colorado Revised Statute 25-12-103. EnCana plans to convert the new compressor to
electric powered motors as produced natural gas volumes increase and as economics warrant and
Middle Fork Compressor Station

those negotiations are underway with Excel Energy to provide three phase power service to the
proposed facility site.
Noise generated will have very little impact on adjacent properties since the compressor is located in
a canyon-like area that will prevent any sound from traveling as well as being located well within the
. boundaries of the subject property far from adjacent properties. In any event, EnCana shall adhere to
the noise standards specified by the Colorado Revised Statutes and the Colorado Oil and Gas
Conservation Commission rules. Given the remote location of the new facility, Staff agrees that
noise will not be a nuisance to area residents.
(C) Impacts on wildlife and domestic animals through the creation of hazardous attractions,
alteration of existing native vegetatii>n, blockade of migration routes, use patterns or other
disruptions.
Response
The site is located within winter rangeland for mule deer, elk, and turkey as identified on the
Division of Wildlife's wildlife distribution maps. Staff referred the application to the Department of
Wildlife (DOW) which provided no comments on the proposal. The Applicant plans to fence the
entire site to minimize conflicts with wildlife.
(D) Affirmatively show the impacts of truck and automobile traffic to and from such uses and
their impacts to areas in the County.
Response
As noted earlier, the Compressor, once filly operational, is expected to generate an average of 4 pick-
up trips per day into and out of the facility because most of the monitoring of the Compressor's
performance will be done remotely. Also as mentioned above, most of this truck travel will be
coming from Parachute on CR 215 which can accommodate the trips according to the Road and
Bridge Department.
The Garfield County Road and Bridge Department has no comments orrequests for this application.
The road to the new compressor site is an existing road that meets the County's standards and does
not foresee a major increase in traffic flow after the construction period and the compressor is online.
No improvements to CR 215 are necessary as a result of this compressor station.
(E) That sufficient distances shall separate such use from abutting property which might
otherwise be damaged by operations of the proposed use(s).
Response
The operations at the facility will not involve any abutting property. The proposed facility will not
encroach upon existing setbacks or reduce current separation distances to abutting properties. Staff
Middle Fork Compressor Station
BOCC-08115105
Page8
agrees that the existing facility is located well within required setbacks and is sufficiently separated
from adjacent properties in all directions.
(F) Mitigation measures proposed for all of the foregoing impacts identified and for the
standards identified in Section 5.03.08 of this Resolution
Special Use 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/or conditional or special use will be issued;
Response
The application includes a reclamation plan that would govern treatment of the site once the useful
life of the facility (20+ years) has expired which includes:
1) Removal of all surface equipment;
2) Restoration and re-contouring of grade to approximate original conditions;
3) Replacement of stockpiled topsoil; and
4) Compliance with all prevailing Colorado Oil and Gas Conservation Commission and
Garfield County regulations governing final reclamation.
Staff recommends the Applicant, as a condition of approval, obtain an approved "Weed Management
and Revegetation Plan" from the County Vegetation Manager that specifically addresses weed
management and revegetation of the site. This plan needs to quantify the amount of surface area to
be disturbed by the Compressor construction. Once this is done we will be able to determine an
amount for a revegetation security.
The security shall be held by Garfield County until vegetation has been successfully reestablished
according to the Reclamation Standards in the Garfield County Weed Management Plan. It is the
responsibility of the Applicant to contact the County, upon successful revegetation establishment, to
request an inspection for bond release consideration.
(B) The County Commissioners may require security before a permit for special or conditional
use is issued, if required. The applicant shall furnish evidence of a bank commitment of credit,
bond, certified check or other security 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 specifu:ations 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;
Response

In the past, the Board has required, as a condition of approval that "A sufficient monetary security,
determined by the Board of County Commissioners, to ensure rehabilitation of the site once
operation has ceased shall be provided by the Applicant. "
Tue Application contains a Performance Bond for $50,000 filed with the COGCC for an E&P Waste
Facility. However, note this BOND is not specifically for the Compressor and is for E&P waste only
such as an evaporation pond. Tue Board may wish to consider some type of security intended to
address proper reclamation, closure and abandomnent of such facility.
