PROJECT INFORMATION AND STAFF COMMENTS
REQUEST: Special Use Permit for the construction and
operation of a natural gas compressor.
APPLICANT: Questar Pipeline Company
LOCATION: A parcel of land located in Section 18, T6S
R93W and Section 13, T6S R94W of the 6th
P.M.; approximately 2 miles west of Rifle off
of CR 264.
SITE DATA: 9.64 Acres
WATER/SEWER: Will not be used
ACCESS: Direct access to CR 264
EXISTING/ADJACENT ZONING: R/L,
I. RELATIONSHIP TO THE COMPREHENSIVE PLAN
The subject property is located within District C - Rural Areas/Minor Environmental
Constraints and District D - Rural Areas/Moderate Environmental Constraints, as designated
by the Garfield County Comprehensive Plan's Management Districts Map.
H. DESCRIPTION OF THE PROPOSAL
A. Site Description: The subject tract is a 9.64 acre parcel located north of CR 264
approximately two (2) miles west of Rifle, among other industrial land uses. The site
has been previously leveled and little vegetation exists. There is an existing, permitted
compressor that is contained within a building currently on the parcel. See sketch
map on page — 6 -
Adjacent Land Uses: This area is an industrial site which supports a number of similar
uses for the oil and gas industry. Snyder Oil, Public Service, Northwest Pipeline and
Umetco Minerals, among others, all have operations in the immediate vicinity. See
vicinity map on pages
• •
C. Project Description: The applicant proposes the construction of a natural gas
compressor, which would supply natural gas from the applicant's existing transmission
line to the Rocky Mountain Natural Gas (RMNG) facility, located approximately
2000 feet to the west. The proposed compressor would be a Caterpillar/Worthington
Model G353TA/HBGG, natural gas-fired unit that would accompany a previously
approved compressor (See attached SUP, page - g - ), and set on a prepared pad
using portable surface mount bases, inside an existing, pre-engineered metal building.
The new compressor would operate in conjunction with the previously approved
compressor during the winter season and, during the rest of the year, the new
compressor would be the only machine in operation. Except for periodic
maintenance, it is assumed the facility would operate 24 hours/day, 365 days/year.
M. MAJOR ISSUES AND CONCERNS
A. Easements: The property where the compressor will be located is owned in fee by the
applicant and the deed is attached on page -/D - .
B. Zoning: The subject property exists within the R/L - Gentle Slopes Lower Valley
Floor - zone district, which does allow this type of facility, upon issuance of a Special
Use Permit.
C. Legal Access: Access to the facility is directly from CR 264 and, it appears, that no
additional easements are required.
D. State and Local Health Standards: An Air Pollution Permit from the Colorado
Department of Health has been issued for the existing compressor and a construction
permit has been issued for the new unit. See permits, pages - //- . The
construction permit has been issued for both units and allows the following annual
emission amounts:
NOx 23.2 tons/year;
CO 23.2 tons/year;
VOC 15.5 tons/year,
which more than doubles the allowed emissions from the previously approved unit.
Staff recommends the operation of the compressors be in accordance with the Terms
and Conditions of the approved construction permit, attached on pages /a aL. / 3 .
E. Noise: The noise generated by the existing compressor unit was measured in three
different locations, showing the following noise levels:
Inside of building, 5 feet from flywheel:
200 feet east of building (fence line):
500 feet southeast of building (entrance to property):
91.9 dBA
59.2
50.5
•
Sound Pressure Levels (in decibels, dB) have been calculated by the manufacturer of
the additional compressor and show that noise generated by the engine/compressor
unit will be approximately 104 dB at the source. The following table shows sound
levels at 20 foot intervals:
Distance From Machine, ft.
A -Weighted, dBA

62.42

59.92
180
X8.39
200
57 98
According to the "Handbook of Noise Control, 1979," when two (2) noise sources
are operating simultaneously, it is possible to calculate the noise levels produced. The
estimated noise levels, at the source within the building, would be 104.25 dBA. At
a distance of 200 feet, the noise level from the two sources is estimated to be 61.6
dBA. For comparison sake, normal human conversation at three (3) feet is in the 60
dB to 65 dB range.
Vibration: The operation of the unit will, most likely, create some vibration on and
near the site. It will be necessary to construct a foundation or pad that will make
vibrations imperceptible, except by instruments, at any point outside of the property
boundary line where the unit will be located. Staff visited the site on August 15,
1996, and was unable to detect any vibration outside of the metal building.
Soils: The Soil Conservation Service identifies the parcel of land to be used for this
proposal as being, in the Arvada loam class, having severe shrink -swell potential.
Conversations with the applicant's engineer have indicated that the proposed method
of setting, the compressor on a prepared pad will be adequate to mitigate any problems
associated with ,the shrink -swell potential of the soil.
• •
H. Wildlife Considerations: Impacts caused to wildlife from the construction and
operation of this facility should be minimal or non-existent as the site is already
industrial in nature and probably not a part of habitat or migration routes.
Fire Protection Measures: The applicant has submitted a list of fire control measures
which appear to be adequate in the event of a fire (see attached fire control measures,
page — / 41 — ). Additionally, the applicant will be required to adhere to the
provisions of the National Fire Code as it applies to this type of facility. Staff
recommends that the applicant file an updated emergency plan with the Rifle Fire
Protection District. In the event of a fire, adequate access to the site does exist.
J. Traffic: It is expected that traffic in the immediate area will increase during the
construction of the facility, estimated to last from two (2) to four (4) weeks. After
completion, it is assumed that traffic will return to pre -construction levels.
IV. SUGGESTED FINDINGS
That proper posting and public notice was provided as required for the meeting before
the Board of County Commissioners.
2. That the hearing before the Board of County Commissioners was extensive and
complete, that all pertinent facts, matters and issues were submitted and that all
interested parties were heard at that meeting.
3. That the application is in compliance with the Garfield County Zoning Resolution of
1978, as amended.
4. That for the above stated and other reasons, the proposed exemption is in the best
interest of the health, safety, morals, convenience, order, prosperity and welfare of
the citizens of Garfield County.
V. RECOMMENDATION
Staff recommends APPROVAL of the application, subject to the following conditions:
1. That all representations of the applicant, either within the application or stated at the
meeting before the Board of County Commissioners, shall be considered conditions
of approval.
The amount of noise to be generated by the operation of this facility be consistent
with the predicted decibels (dB) as indicated herein.
The construction of the foundation or pad for the engine -compressor unit be done in
a manner to prevent perceptible vibration from occurring outside of the property
boundary as it exists on the Property Survey Map. All construction will be done with
• •
respect to the shrink -swell potential of the soil, in order to mitigate any possible
problems associated with the shrink -swell potential of the soil.
4. Approval is subject to adherence to the Terms and Conditions under which the
construction permit, from the Colorado Department of Public Health and
Environment has been issued, as well as any other permits which may be required for
the construction or operation of this facility.
5. That the applicant will apply for and receive any and all building permits associated
with the modification of the building which will house the compressor facility, if
required by the 1994 Uniform Building Code.
6. That all out-of-state vehicles or equipment to be used for the construction of this
facility be registered or apportioned within the State of Colorado or the County of
Garfield.
7 That the applicant consult with the Rifle Fire Department and file an updated
emergency plan with said Department.
