Chevron North American Exploration and Production Company ii Piceance Basin Natural Gas Development Program
Introduction
Chevron North America Exploration and Production Company (Chevron) is submitting a Garfield
County Special Use Permit (SUP) application for the proposed construction of a temporary
Produced Water Management System (PWMS) needed for the disposal of excess produced water.
The facility will be located on the northern portion of an existing Colorado Oil and Gas
Conservation Commission (COGCC) approved well pad [Skinner Ridge 598- 35 -BV; American
Petroleum Institute (API) No. 05- 045 - 14909], which is currently being used as a centralized
service pad for hydraulic fracturing operations. The temporary PWMS is needed to support
current operations associated with the development of production wells that are necessary prior to
the construction of a permanent water management system [large volume tank(s) and associated
water transfer equipment]. The temporary PWMS transfers produce water through a 5.3 mile,
4.5 -inch nominal pipeline to a COGCC permitted injection well [Underground Injection Control
(UIC) Facility Number: 159,213] for disposal.
Chevron is currently developing its natural gas reserves located in the central Piceance Basin (see
Maps attachment — Figure 1). Chevron is the owner of about 54,000 contiguous acres north of De
Beque, Colorado. The company also controls additional surface and severed mineral rights in the
vicinity. Development of the natural gas field is referred to as the Piceance Basin Natural Gas
Development Program (Program), which also is known as the Skinner Ridge Field.
In 2006 Chevron installed exploratory delineation wells that proved the value of the Skinner
Ridge Field. Based on these favorable results, installation of production wells and supporting
infrastructure was initiated in 2007. Required infrastructure included well pads, roads, pipelines,
and construction offices needed to support the extraction and transfer of natural gas to market and
the management of condensate and produced water generated as part of the natural gas
production.
The Program drilling and construction activities are currently centered within the Clear Creek
(tributary to Roan Creek) drainage (see Maps attachment - Figures 2 and 3) where two state -of-
the -art directional drilling rigs are being utilized for production well installation. Existing
infrastructure includes: four well pads and associated access roads, temporary employee housing,
temporary construction offices, fresh water storage, and pipelines. The recently permitted Central
Production Facility (CPF) that performs separation, dehydration, and compression operations
needed to move the natural gas to market is currently under construction. Gas from the CPF will
be transferred to the previously permitted 30 -inch sales pipeline that delivers the natural gas to
regional pipelines for ultimate delivery to the marketplace place.
The Program development will require additional infrastructure including the following:
production wells (eventual field build out may include 2,000 or more wells over the next 20 to 30
years), access roads, construction / permanent offices, temporary housing, utilities (water,
sewage, and electricity), storage areas, water storage, pipelines (gas, condensate / produced water,
fresh water), and processing / treatment equipment (similar to the current CPF). Operational
activities needed to support the Program development will require: drilling, well installation and
development, equipment transfer, material management, road maintenance, and general
maintenance.
The following narrative has been generated to provide the necessary information for the requested
development of the temporary PWMS.

Chevron North American Exploration and Production Company 1 Piceance Basin Natural Gas Development Program
Nature and Character of Special Use Permit
Please submit, in narrative form, the nature and character of the Special Use requested. Submit
plans and supporting information (i.e. letters from responsible agencies). Include specifications
for the proposed use including, but not limited to, the hours of operation, the number and type of
vehicles accessing the site on a daily, weekly andlor monthly basis, and the size and location of
any existing and/or proposed structures that will be used in conjunction with the proposed use,
and provisions for electric power service and any other proposed utility improvements. Be
specific,
1.1 Temporary Produced Water Management System Purpose
The temporary PWMS purpose is to collect produced water from operational natural gas wells,
filter the produced water, and pump it into a proposed produced water disposal pipeline (A
Pipeline Development Permit application detailing the disposal pipeline will be submitted to
Garfield County). The temporary PWMS equipment would be located on the COGCC approved
well pad Skinner Ridge 598 -35 -BV (API Well Number: 05 -045- 14909), which will be referred to
as well pad 35 -BV for the remainder of this application. The disposal pipeline transfers the water
to a COGCC approved disposal well located on well pad Skinner Ridge (SKR)- 598 -8 -1 (API
Well Number: 05- 045 - 11975; UIC Facility Number: 159,213). The anticipated need for the
temporary PWMS facilities at well pad 35 -BV is expected to be less than 12 months when a
proposed permanent produced water management facility would be constructed.
Produced water passing through the temporary PWMS would come from two sources. Early
operations would involve the transfer of produced water from tanker trucks into the well pad 35-
BV storage tanks, which would reduce truck traffic and the related impacts going to the SKR-
598-8-1 injection well pad (SKR- 598 -8 -1 will be referred to as injection well 8 -1 for the
remainder of this application). When the currently under construction CPF becomes operational a
temporary pipeline will transfer water directly from the CPF separation equipment to the
temporary PWMS equipment. Both types of transfers would cease when the permanent produced
water management facility becomes operational.
COGCC permitted operations at well pad 35 -BV include drilling of up to 22 directional natural
gas production wells, placement of primary liquid / gas separation equipment (connected to
pipelines that transfer the gas and liquid to the CPF), and the placement of hydraulic fracturing
equipment including frac tanks [frac tanks are 500 barrel (bbl) (equivalent to 21,000 gallon)
mobile tanks typically used to store water used in hydraulic fracturing operations - see Typical
Frac Tank schematic provided as an attachment to this application], pumps, materials storage, and
control equipment. Hydraulic fracturing operations are currently in progress at well pad 35 -BV.
Drawing PBSR- 59835BVW- PIP- PLN -URS- 00000- 00002 -00 illustrates the general placement of
the hydraulic fracturing equipment and the relative position of the proposed temporary PWMS
(see Drawings attachment).
NOTE; The CPF removes the majority of water and condensate (a blend of low - density
hydrocarbons) from the extracted natural gas, which is not removed by the primary separation
equipment on the well pad, prior to gas transfer into the existing export pipeline. Water and
condensate removal is necessary to prevent pipeline corrosion, hydrate formation and multiphase
flow problems, and to collect the marketable commodity for sales (source of propane, butane,
pentane and heavier hydrocarbon fraction).
Pumping produced water to the frac tanks on well pad 35 -BV is expected to occur on a
continuous basis. From the frac tanks, the produced water would be pumped through 10 micron

Chevron North American Exploration and Production Company 2 Piceance Basin Natural Gas Development Program
filters, into the disposal pipeline, also on a continuous basis. The filtered, produced water would
then flow 5.3 miles, to the 8 -1 injection well for disposal.
A separate SUP application will be prepared and submitted to Garfield County for construction
and commissioning of a permanent water management system when the final site selection
process and design requirements are complete (mid - 2009). The temporary PWMS would be
removed from well pad 35 -BV when that facility is commissioned.
Additional details pertaining to the proposed temporary PWMS can be found in the following
sections.
1.2 Location
The proposed temporary PWMS would be located about 0.1 miles west of the intersection of two
existing ranch roads near the confluence of Clear Creek and Tom Creek (see Maps attachment -
Figure 2). This intersection is located about 2.5 miles north northwest of the end of County Road
(CR) 211 and within the Program area. The Chevron development can be accessed from
Interstate 70 (I -70), exit 62, by traveling north on local Road 45N north of De Beque, Colorado
(also known as Roan Creek Road or CR 204).
The footprint of the proposed temporary PWMS is about 0.86 acres of the northern end of the
COGCC approved well pad 35 -BV (well pad disturbance is about 3.4 acres). A general
coordinate for the facility is 39 °34' 19.77 "N latitude, 108 °21'0.18 "W longitude NAD 83 / WGS
84.
1.3 Equipment List and Operations Description
The following equipment would be placed on well pad 35 -BV to support operation and
maintenance of the temporary PWMS:
• Ten - 500 bbl (21,000 gallon) frac tanks,
• Two - duplex -type 10 micron filters,
• Two — 5,000 gallon diesel tanks
• Two - 10 horsepower (HP) filter /charge pumps,
• Two - 250 I-P water transfer pumps,
• One - 20 HP instrument air compressor package (only required when the CPF becomes
operational — will be powered by CPF gas turbine generator),
• One - 10 bbl buried sump -tank, and
• Temporary diesel generator ( <1200 HP) and related switchgear [on -site power supply
needed prior to the commissioning of the CPF gas turbine]
The temporary PWMS would be operated in accordance with the following requirements:
• All pumps would be electric -motor driven powered by the on -site diesel generator until
power is available from the CPF gas turbine,
• Injection pumps would be equipped with high pressure shutdown devices,
• All pumps would be equipped with sensors that will be constantly monitored from the
CPF control room (when the CPF becomes operational),
• All tanks would be equipped with level sensors that would be constantly monitored from
the CPF control room,

Chevron North American Exploration and Production Company 3 Piceance Basin Natural Gas Development Program
• Transfer lines at the temporary PWMS would be equipped with totalizing flow meters
(with remote monitoring capability) to record the volume of produced water being
transferred to the 8 -1 disposal well, and
• Monitoring equipment at the 8 -1 disposal well would include casing -head pressure and
totalizing flow meters that could be monitored remotely.
All equipment will be designed / installed in accordance with current engineering standards [e.g.,
API, American Society of Mechanical Engineers (ASME), American Society for Testing
Materials (ASTM), American Welding Society (AWS), International Fire Code (IFC), National
Electrical Code (NEC), National Electrical Manufacturers Association (NEMA), National Fire
Protection Association (NEPA), etc.].
1.4 Hours of Operation
Construction of the temporary PWMS will occur during the normal site working hours of 6:30
AM through 5:00 PM (6:30 PM for some supervisory personnel), Monday through Friday.
Once the temporary PWMS is in place and operational the system would be online 24- hours,
seven days a week. The system would have the capability to be controlled from the CPF, which
would minimize the need for on -site personnel. Personnel would visit the location as needed to
perform tasks such as system checks and routine maintenance.
1.5 Schedule
Upon approval, construction activities would begin in mid -June 2009 and require about 50 days
to complete (ending in early August 2009). Commissioning of the proposed temporary PWMS is
expected to take place in mid- August 2009.
1.6 Vehicles / Traffic / Regulatory Requirements
An overall traffic impact study (Traffic Impact Study for Valley and Mesa Development, see
Traffic Impact Study attachment) was completed in August, 2008, that formally addressed the
effects of the vehicles required for the first ten years of the Program. A copy of the study is
provided as an attachment (see Traffic Impact Study attachment). The study concluded that while
the Program would result in increased traffic on CR 204 and 211 (up to 3083 vehicles per day
during the simultaneous construction of multiple facilities), the existing roadway could handle the
loads without major improvements. The study was submitted to, reviewed and approved by the
Garfield County Assistant Engineer (August 2008). The study summary stated "The existing
roadway on CR 211 can accommodate the additional traffic volumes generated by the Chevron
Program with little or no impact to the existing level of service" (see page 16 of Traffic Impact
Study attachment).
The Program is currently under evaluation to determine if the development will progress as
represented in the Traffic Impact Study. The study assumed three drilling rigs operating in the
Clear Creek valley. Program planning is now anticipating the development to be downsized to a
one or two rig project. The one or two rig scenario would significantly reduce traffic volume on
area roads.
Periods of increased vehicle traffic would be expected during the proposed project as construction
materials (e.g., secondary containment material, gravel, storm water controls) and facility
equipment (e.g. pump skids, generator, filter assemblies, and tanks) would be delivered to the
Doc. No.: PBSR- ALL -RGL- PMT -URS- 000000- 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 4 Piceance Basin Natural Gas Development Program
site. Earthmoving equipment and the associated work force is currently in place at the CPF
construction site, so very little additional traffic would be expected during the construction phase
of the project. The well pad 35 -BV site is remote and is located approximately 2.7 miles north of
Hiner Gate, where CR 211 ends. The proposed project site is located a substantial distance from
general public traffic, and therefore traffic related impacts to CR 204 and 211 are expected to be
to minimal.
Because well pad 35 -BV has already been constructed (graded, etc.), heavy equipment use would
be limited to building the secondary containment berm and installing the tanks, pumps, filters,
generators, and control systems. This heavy equipment may include, but is not be limited to,
trucks and flat -bed trailers; dump trucks; loaders; bull dozers; backhoes; graders; scrapers; rollers;
dust suppression water tanker trucks; and off - loading equipment. This equipment would typically
operate 10 to 12 hours per day, 5 days per week.
Vehicles required for the proposed well pad 35 -BV temporary PWMS construction would include
heavy duty pickup trucks to oversized vehicles for transporting large equipment and components.
The majority of the vehicles would be sized to meet posted weight restrictions, however heavy
and wide loads may be required to deliver large equipment such as the tanks. Vehicles hauling
equipment and materials would abide by Garfield County Road and Bridge Departments oversize
/ overweight regulations. All oversize / overweight vehicles would obtain the necessary permits
and carry a letter showing proof that they can operate under a known bond holder on file with
Garfield and Mesa County Road and Bridge Departments. Because of the location, no vehicles
would be working within a Garfield County Right -of -Way.
An estimated ten vehicles will be required to deliver construction and site equipment with an
additional 20 vehicles for delivery of the temporary PWMS components. The proposed
construction is expected to take about 50 days to complete (dependant on weather delays), and
would require a workforce of approximately 20 employees. Efforts would be made to reduce
workforce vehicle trips by the use of carpooling, vans, and / or buses. Following construction,
two individuals will be required to service the temporary PWMS on an infrequent periodic basis.
Chevron has contracted with Hyland Enterprises, Inc. (see attached Hyland Contract) to
supplement the County snow removal operations (scheduled hours 5 am to 5 pm) and provide
general maintenance of the private access roads. Road closures are still possible during large
snowfall events, which should not be an issue with the proposed construction schedule.
1.7 Civil Specifications / Regulatory Requirements
Well pad 35 -BV has been graded for drilling operations in accordance with COGCC
requirements, which includes a re- vegetation plan and bond. The area of the pad affected by the
temporary PWMS will require re -work to install the secondary containment berm and equipment,
but the existing storm water controls should be adequate for the temporary PWMS modification.
Storm water / erosion controls were installed as part of the well pad 35 -BV construction and will
continue to be used and maintained in accordance with the best management controls specified by
the site Storm Water Management Plan (SWMP) (see attached SWMP and associated
Construction Storm Water Permit). An addendum to the SWMP for specific storm water controls
for this location has been provided in Geotechnical Engineering Group, Inc. (GEG) Drawings for
the 35 -BV Access Road Storm Water Management Plan and Storm Water Management Plan
Well Pad 598 -35 -BV (see Erosion Control Drawings attachment). Details of the site storm water
controls [best management practices (BMPs)] are provided on the GEG Drawing Storm Water
Doc. No.: PBSR - ALL -RGL- PMT -URS- 000000- 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 5 Piceance Basin Natural Gas Development Program
Management Plan Well Pad SKR 578 -35 -BV BMPs (see Erosion Control Drawings attachment).
Bi- weekly SWMP inspections are currently being conducted to ensure site stabilization measures
are adequate and / or identify areas that need repair / improvement. Any construction dewatering
activities will be implemented in accordance with the provisions of the existing Construction
Storm Water Permit with required information provided in the Site Specific SWMP.
Available topsoil has been stockpiled and stabilized for the eventual site reclamation in
accordance with specific SWMP requirements. Seed mixes used for site stabilization and
revegetation are provided in the Chevron Re- vegetation Specification (see Relevant
Specifications attachment). Noxious weeds were removed as part of the well pad construction
and berms / stockpiles will be monitored and controlled for noxious weeds throughout the life
cycle of well pad 35 -BV. General information concerning the area reclamation plan for the area
is provided in Section 9.2.
The proposed construction activities do not require a Colorado Department of Public Health and
Environment ( CDPHE) Air Pollution Emission Notice (APEN) for fugitive dust because of the
limited size of disturbance ( <25 acres) and limited site construction activities ( <six months).
1.8 Major Equipment Descriptions / Regulatory Requirements
A primary piece of large equipment that would be temporarily located at the site is the diesel
generator. The site generator is exempt from CDPHE, Air Pollution Control Division (APCD)
regulation because of the size <1200 HP and limited time it would be operational at the site ( <12
months). The unit would qualify as a temporary non -road engine (Colorado Regulation No. 3,
II.D.1.eeee).
The diesel and produced water tanks will be provided with secondary containment in accordance
with the site Spill Control and Countermeasures (SPCC) Plan (see SPCC attachment).
1.9 Structural Specifications / Regulatory Requirements
There will be no structures located on the well pad 35 -BV.
1.10 Electrical Utilities / Regulatory Requirements
As mentioned in Section 1.8, power for the site would initially come from the temporary
generator, which is exempt from CDPHE, APCD regulations. Once the gas - powered turbine
generator previously permitted at the CPF is operational, it will supply needed power to well pad
35 -BV. It is anticipated the temporary generator would be on -site for two to six months before
the CPF gas turbine comes online.
1.11 Floodplain
No Federal Emergency Management Agency (FEMA) flood map was available for the Program
area. To properly evaluate the area for flooding issues, a preliminary 100 -year floodplain was
developed for Clear Creek and its tributaries using HEC -RAS in accordance with FEMA
guidance and specifications. The model surface was generated from a combination of Light
Detection and Radar (LIDAR) (sampled with a 9 ft x 9 ft grid) and USGS topographic data. The
original floodplain indicated that the southern portion of well pad 35 -BV was impacted by the
floodway fringe.
Doc. No.: PBSR- ALL-RGL- PMT -URS- 000000- 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 6 Piceance Basin Natural Gas Development Program
In order to validate the findings of the preliminary floodplain analysis, the model was rerun using
surveyed cross sections collected from the vicinity of well pad 35 -BV and the LIDAR data set re-
sampled as a 1 ft x 1 ft grid. Updated, area specific volumetric stream discharge data also was
incorporated into the revised analysis.
Findings of the revised analysis indicated that the floodplain remains within the existing Clear
Creek stream channel. The revised floodplain is shown on Figure 3 (see Maps attachment). A
detailed analysis of the entire Clear Creek floodplain is currently in progress and will be provided
to the County as a final report in 2009. Interim reports will be generated on an as needed basis
for facilities that are proposed for construction in areas in the vicinity of the preliminary
floodplain analysis. Facilities will be placed to avoid the floodplain when practical. Floodplain
permits will be applied for when it is necessary to build structures in those areas.
1.12 Noxious Weeds
Information on noxious weeds was reported in a Clear Creek biological survey completed by
WestWater Engineering during May 2007 (see Section 9.1.3). The survey involved the majority
of Clear Creek basin including the surrounding steep talus slopes. Survey results indicated that
the entire drainage is affected by noxious weeds.
More recently, WestWater Engineering was asked to generate a noxious weed analysis and plan
to specifically address the facility areas that are proposed for development. The findings from
that study were captured in the Chevron — Tom Creek Integrated Vegetation and Noxious Weed
Management Plan (IVNWMP) (dated April 2008). The study evaluated a project area of
approximately 400 acres in size that includes the well pad 35 -BV site. The study indicated that
the most prevalent State of Colorado and Garfield County listed weeds were common mullein
(Verbascum Thapsus), musk thistle (Carduus nutans), houndstongue (Cynoglossum officinale),
and downy brome (Bromus tectorum). Within the exact location of well pad 35 -BV the most
common noxious weed species found include areas containing Tamarisk (Tamarix sp.), common
mullein, and houndstongue, and weed patches of musk thistle. The IVNWMP is provided as an
attachment for reference.
In general terms, all identified noxious weeds were already removed during the initial site grading
for construction of well pad 35 -BV. Maintenance operations will include continuing control of
all noxious weeds using a combination of removal and re- vegetation techniques.
Recommended weed control measured were detailed in the IVNWMP, which are currently being
implemented by Brady Construction for the Program. Chevron is engaging in a proactive, long-
term weed management program to address the noxious weed issue.
1.13 Safety / Security / Emergency Response
Chevron has initiated coordination activities to ensure that local fire departments, medical
facilities, and emergency response providers are aware of the Program activities and hazards.
Detailed Program facility maps along with the associated GPS coordinates have been provided to
the Garfield County Sheriff's Office and local fire departments as part of the Program Emergency
Response Plan (ERP). Multiple meetings have been held with the De Beque and Rifle fire
departments and associated Emergency Management System (EMS) Response Agents to discuss
hazards specific to a natural gas production field. Field trips and tours (as recent as spring 2007)
have also been also been conducted with the De Beque and Rifle fire departments and EMS
teams, and members of the Bureau of Land Management (BLM) Rocky Mountain Coordinating
Doc. No.: PBSR - ALL -RGL- PMT -URS- 000000 - 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 7 Piceance Basin Natural Gas Development Program
Group. The BLM Rocky Mountain Coordinating Group is an interagency fire management group
that includes six federal agencies and the Colorado State Forest Service. Site emergency
response personnel have also worked with the Rifle Fire department and the BLM Rocky
Mountain Coordinating Group on a joint Fire Fighters / Oil Field Operators Orientation that the
BLM presented in the fall of 2007. Follow up meetings will be held with these organizations as
the various facilities are constructed and become operational.
Members of the De Beque emergency response team have also completed Chevron's safety
orientation for the Program. Efforts have been made to provide safety training to local
landowners.
Chevron safety personnel have also had extensive discussions with local emergency medical
service providers including St. Mary's Hospital and Medical Center (Grand Junction), CareFlight
Air Ambulance (associated with St. Mary's), and Grand River Heath and Safety Center.
Additional meetings with Community Hospital (Grand Junction) and Grand River Hospital
(Rifle) are being planned. Personnel also have met with a local physicians group (including Dr.
Krueger and Dr. Papenfus) that was organized to address the increasing demands on emergency
response.
All site personnel are trained to report fires or other emergencies in accordance with the Chevron
ERP (see ERP attachment). The ERP is a living document that incorporates changes to facilities
and operations as the various systems come on line. Coordination meetings have been held with
the De Beque Fire Chief and other emergency agencies to address site specific issues.
Due to the fact that well pad 35 -BV will be used for natural gas production and handling
activities, no smoking will be permitted at the site during or following construction.
All employees and contractors will comply with the provisions of the Chevron Piceance Basin
Skinner Ridge Hazard Elimination / Health and Safety (HES) Plan (see attached HES Plan).
Applicable requirements will be detailed in Master Service Agreements established with
contractors and must be met prior to commencement of any activity. Noncompliance with the
policy will result in immediate dismissal and termination of the contract.
2 Water Supply / Wastewater Management Systems
If you will be using water or will be treating wastewater in conjunction with the proposed use,
please detail the amount of water that would be used and the type of wastewater treatment. If
you will be utilizing well water, please attach a copy of the appropriate well permit and any
other legal water supply information, including a water allotment contract or an approved water
augmentation plan to demonstrate that you have legal and adequate water for the proposed use.
Temporary portable sanitary facilities (port -o -lets) may be supplied and located at the proposed
PWMS site during the facility construction. No permanent restroom facilities will be provided at
that location. Because of limited follow on service requirements at the location, workers would
use adjacent restroom facilities (e.g., well pad 35 -BV facilities or the CPF), as needed, once the
facility has become operational.

of the Zoning Regulations:
(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
he constructed in conjunction with the proposed use.
8.1 Water and Sanitation Service
As discussed in Section 2, no permanent water or wastewater services will be provided at the
proposed location due to adjacent facilities being adequate for normal operations. Temporary
portable sanitary facilities (port -o -lets) may be supplied and located at well pad 35 -BV during
construction and drilling / completions operations, however no permanent restroom facilities will
be provided at the pad. Workers will use adjacent restroom facilities (e.g., nearby well pads or
the CPF), as needed, once the facility has become operational. Bottled water will be provided as
needed for construction crews.
8.1.1 Sanitation Services
The well pad and the proposed temporary PWMS area will be maintained in a clean, safe, and
sanitary condition, free of weeds or refuse at all times.
Down Valley Septic provides trash collection services for the Program (see Down Valley Septic
Service Agreement attachment). At least one 30 -cubic yard, "bear- proof', roll -off container will
be provided on -site to manage miscellaneous solid waste. The roll off will be constructed of steel .
including the lid(s). The container lid will be secured using a steel bar across the top of the lid
with positive connection and a hasp lock at the sidewalis to restrict entry (or equivalent). Site
personnel will be informed of the proper closure procedures. No hazardous materials will be

8.2 Road Improvements / Issues
Submit a statement that specifically responds to each of the following criteria from Section 5.03
of the Zoning Regulations:
See Section 8.1 above regarding the establishment of utilities adequate to provide water and
sanitation service;
(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.
As mentioned in Section 3, a Garfield County driveway permit would not be required for this
location. Chevron and the Garfield County Road and Bridge Department coordinate activities
needed to maintain the surface of CR 211 to allow continuous access to the site. Additional
coordination with the County Engineering Department is currently underway for planned
improvements to CR 204.
All private roads associated with the Program are maintained by Hyland Enterprises, Inc. to
ensure year round access to all facilities. A copy of the Hyland contract is provided as an
attachment (see Hyland Contract attachment).
The Colorado River Bridge that provides access to De Beque from 1 -70 was recently
reconstructed and reopened to traffic in the summer of 2008. The bridge is capable of handling
vehicle loads up to 180,000 pounds (lbs). According to Eric Eruton, Road Supervisor with Mesa
County, there are no restrictions for vehicles crossing the new bridge weighing 180,000 lbs or
less. Vehicles that exceed 180,000 lbs may be able to cross the bridge but would require an
engineering analysis to do so. The other option for vehicles exceeding the 1 80,000 Ibs weight
restriction that exit I -70 at De Beque (Exit 62) is to travel east on the frontage road to W.5 road
and back to 45 Road (Roan Creek). However, due to low bridge overpasses there is a height
restriction of 15 -ft on this route. Operators of vehicles greater than 180,000 lbs and 15 -ft high
that wish to avoid the Colorado River Bridge in De Beque need to exit 1 -70 at Exit 75 (Parachute)
and continue west on the frontage road toward De Beque to W.5 road and back to 45 Road (Roan
Creek) north of De Beque. AlI overweight/oversized regulations would be followed and the
appropriate permits would be secured prior to dispatch.
8.3 Visual Effects
Submit a statement that specifically responds to each of the following criteria from Section 5.03
of the Zoning Regulations:
(1) See Section 8.1 above regarding the establishment of utilities adequate to provide water
and sanitation service;
(2) See Section 8.2 above regarding street improvements adequate to accommodate traffic
volume generated by the proposed use;
(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.
The proposed project is located in a remote region of Garfield County and will have no direct
visual effect on adjacent landowners. Visual effects include the physical presence of the facility,
equipment, and operational traffic. No outdoor lighting would be required to construct or operate
the proposed temporary PWMS. No permanent facilities will be constructed as part of this
development.

9 Use Specific Standards
Depending on the type of Special Use Permit requested, you may need to respond to additional
review standards in the Garfield County Zoning Resolution Section 5.00 [Supplementary
Regulations]. This may include uses such industrial uses [section 5.03.07 & 5.03.08], Accessory
Dwelling Units [section 5.03.21], Utility line/Utility Substations, etc. Specific sections of the
Zoning Resolution which can be located on the Garfield County web site at
hnp:// www. garfieldcounty. com/ building oand_planning /index.htm, or information can be
obtained from this office.
Because well pad 35 -BV supports operations associated with the development of natural gas,
additional requirements must be met for Garfield County approval. The following details the
applicable information not provided in Sections 1 through 8 that are required by the supplemental
regulations.
9.1 Well Pad 35 -BV and Proposed Temporary Produced Water Management System Impacts
5.03.07 industrial Operations: Industrial Operations, including extraction, processing,
fabrication industrial support facilities, mineral waste disposal, storage, sanitary landfill, salvage
yard, access routes and utility lines; water impoundment as defined in Section 2.02.53 (added
2008-68), shall be permitted, provided:
(I) The applicant for a permit for industrial operations shall prepare and submit to the Planning
Director ten (10) copies of an impact statement on the proposed use describing its location,
scope, design and construction schedule, including an explanation of its operational
characteristics. One (1) copy of the impact statement shall be filed with the County
Commissioners by the Planning Director. The impact statement shall address the following:
A preliminary plan of development that included a discussion of possible Program impacts was
provided to the County in April, 2007. However, site conditions, capital constraints, and
procurement delays have resulted in a number of changes to that original plan. Supplemental
updates to the original plan have been included in interim permit applications. The following
addresses the impacts associated with the proposed temporary PWMS.
9.1.1 Water Use and Water Quality Control
(A) Existing lawful use of water through depletion or pollution of surface run -off,
stream flow or ground water;
No water will be discharged from any of the State's waters without applicable permits (Colorado
Division of Natural Resources, Colorado Water Quality Control Commission and CDPHE). Any
discharge will meet the drinking water standards controlled by the CDPHE.
Use of produced water current falls outside of the regulation of the Colorado Division of Water
Resources (Department of Natural Resources), but is regulated by the COGCC.
Discharges associated with this facility would be limited to possible ground water dewatering
operations associated with construction. If ground water dewatering operations are required (not
expected because of the elevation difference between the site and the creek) a Minimal Industrial
Discharge permit will be obtained and provisions of the SWMP will be followed.
The PWMS frac tanks and fuel pumps associated would be placed in a secondary containment
structure to minimize the possibility migration to the waters of Colorado in the event of a spill.

A separate SUP will be prepared and submitted to Garfield County for construction and
commissioning of a permanent water management system. Once the permanent water
management system is approved, the temporary PWMS and associated equipment will be
decommissioned.
Although temporary portable sanitary facilities (port -o -lets) may be supplied and located at the
proposed project location during construction of the temporary PWMS, no permanent restroom
facilities will be provided at the pad. Following pad construction and well drilling / development,
this facility will be used intermittently, for limited amounts of time and will not require long -term
service. Therefore workers will use adjacent restroom facilities (e.g., nearby well pads or the
CPF), as needed, once the facility has become operational.
9.1.2 Vapor, Smoke, Noise, Glare, and Vibration
(B) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or
vibration, or other emanations;
The proposed activities are not expected to generate significant amounts of vapor or smoke.
Potential sources would be from the temporary diesel generator (to supply power to the pumps for
short periods of time, less than 12 months, prior to start -up of the CPF turbine), and diesel
powered trucks and / or heavy equipment. The temporary diesel generator and all vehicles will
receive appropriate maintenance to minimize emissions.
Construction activities on the gravel pad will generate a limited amount of dust in the vicinity of
the project site, but this would be controlled in accordance with the designated Rust Constructors
Fugitive Dust Plan (see Fugitive Dust Control Plan attachment). The Plan also addresses dust
control measures to be used on access roads to limit dust generated by construction vehicles.
A limited amount of welding may be performed at this location but all welding activities are
strictly governed by Chevron's Hot Work Specifications, and screens will be used as necessary.
Noise sources at the site include the temporary diesel generator, general truck traffic, material
handling, and limited amounts of maintenance activities and small scale fabrication. Truck
traffic, material handling, and maintenance / fabrication activities will occur during normal
working hours and the associated noise levels will fall well within the current Colorado Revised
Standards. The only continuous noise source is the temporary diesel generator that will be used
to supply power to the pumps for a short period of time, Tess than 12 months, prior to start -up of
the CPF turbine. Findings of a noise study generated for the CPF installation addressed possible
noise sources in the area are summarized in Section 9.3.1.
9.1.3 Wildlife and Domestic Animal Ilnpacts
(C) Impacts on wildlife and domestic animals through the creation of hazardous
attractions, alteration of existing native vegetation, blockade of migration routes, use
patterns or other disniptions;
The Skinner Ridge Field is located in a remote area of Garfield County where the valley floor is
used for Natural Gas extraction, agriculture and cattle grazing. The Clear Creek valley is a steep
canyon cut into the Roan Plateau that has limited public access. Populations of elk, deer, bear,
wild turkeys, raptors, and game birds are present in the area.
Doc. No,: PBSR- ALL-RGL- PMT -URS- 000000 - 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 13 Piceance Basin Natural Gas Development Program
Chevron has an on -site land manager who monitors and maintains the agricultural and grazing
operations.
Information about wildlife in the area is included in the following studies / documents (reference
copies provided in the Biological Survey attachment):
• Clear Creek Biological Survey, WestWater Engineering, May 2007, 24 pages;
• Biological Survey for Chevron / Texaco 8 -inch Natural Gas Pipeline, Clear Creek,
Garfield County, Colorado, WestWater Engineering, July 11, 2006, Letter Report, 6
pages; and
• Wildlife Use Area Determination, Natural Diversity Information Source, Colorado
Division of Wildlife, November 30, 2008, 14 pages.
The findings of the surveys revealed some sensitive plant species and raptor populations
surrounding the project site, however, no sensitive populations were identified in the direct
vicinity of the proposed project. The Wildlife Use Area Determination report identifies the
Skinner Ridge Field as:
• American Elk Winter Range, Winter Concentration, and Severe Winter Range,
• Mule Deer Summer and Winter Range,
• Black Bear Overall Range, and
• Wild Turkey Overall Range
No specific wildlife corridors were identified in the vicinity of the proposed project although
wildlife crossings are frequently noted throughout the Program area. Chevron strictly enforces
the speed limit along the CR 204, CR 211, and their private access roads to minimize wildlife /
vehicle collisions.
Sufficient open ground surrounds well pad 35 -BV that will allows wildlife to move through the
area to feeding areas. Elk and deer typically use riparian areas for feeding, which are located
west of the site along Clear Creek.
Outdoor food storage will be prohibited to prevent the attraction of animals. No animals or pets
will be housed at any Chevron facility.
9.1.4 Traffic Impacts
(D) Affirmatively show the impacts of truck and automobile traffic to and from such
uses and their impacts to areas in the County;
A Program traffic impact study titled "Traffic Impact Study for Valley and Mesa Development"
was completed in August, 2008 (see Traffic Impact Study attachment). The study formally
addressed the effects of the vehicles required to support the Program development for the first ten
years. The study projected up to 3083 vehicles per day would use CR 211 during peak operations
in the Clear Creek Valley during 2009. However, that projection was made using an assumption
of three operational drill rigs in the valley. Current planning for 2009 would reduce the number
of rigs in the valley to a maximum of two, which would reduce the peak traffic volumes.
Using current federal and state roadway design guidance, the Traffic Impact Study concluded
(assuming the three rig scenario) that "the existing roadway on CR 211 can accommodate the
additional traffic volumes generated by the Program with little or no impact to the existing level
of service" (see page 16 of Traffic Impact Study attachment).

Chevron has contracted with Hyland Enterprises, Inc. to provide ongoing maintenance to CR 211
that will support the continuing traffic loads. The contract includes dust control measures that are
being implemented in accordance with the Rust Constructors Fugitive Dust Control Plan (see
Fugitive Dust Control Plan attachment). Sections of CR 211 that are identified as having safety
issues will be upgraded as needed in coordination with the Garfield County Road and Bridge
Department.
Chevron is providing funding to upgrade CR 204 (primary site access road from I -70), which will
include realignment of portions of the road to address safety concerns and surface material
improvements to increase the life of the road.
9.1.5 Adjacent Owner Impacts
(E) That sufficient distances shall separate such use from abutting property which might
otherwise be damaged by operations of the proposed use(s);
Well pad 35 -BV is adjacent to Colorado Nature Ranch LP property (Garfield County Parcel
Number Parcel No. 2139- 342 -00 -009), lying approximately 0.5 miles to the west. The
Colorado Nature Ranch LP property is zoned as Resource Land and is currently used primarily
for seasonal hunting. There are no adjacent permanent facilities or operations that would be
affected by proposed construction and operation. The proximity of the Colorado Nature Ranch
LP property was addressed as part of the CPF noise study.
9.1.6 Mitigation Measures
(F) Mitigation measures proposed for all of the foregoing impacts identified and for the
standards identified in Section 5.03.08 of this Resolution
General mitigation measures have been discussed in Sections 9.1.1 through 9.1.5. Specific
mitigation measures are discussed in more detail in Sections 9.3.1 through 9.3.6.
9.2 Site Reclamation / Bonding
(2) Permits may be granted for those uses with provisions that provide adequate mitigation for
the following:
9.2.1 Reclamation Plan
(A) A plan for site rehabilitation must be approved by the County Commissioners
before a permit for conditional or special use will be issued;
The temporary generator will be removed from the site as soon as the CPF gas turbine becomes
operational. When the temporary PWMS is no longer required, the equipment will be removed
and the secondary containment berm will be removed or re- graded as necessary to allow fracing
and drilling operations to proceed. Gravel from operational areas may be stockpiled and reused
for the final grade. Final reclamation of well pad 35 -BV will be in accordance with the COGCC
guidelines.
When the Skinner Ridge Field is depleted, the entire Clear Creek Valley will be reclaimed. The
reclamation process will include removal of equipment, foundations, and gravel or paved pads.
The area then will be graded to the original contours, stockpiled topsoil will be replaced, and the
area will be planted with native vegetation. Reclamation and re- vegetation activities will be in
accordance with requirements outlined in Garfield County Zoning Resolution 5.02.21 (11).

Specific details of the re- vegetation / reclamation activities are provided in Section 4.0 of the
IVNWMP (see page 13 of the IVNWMP attachment), the URS Specification for Revegetation of
Disturbed Areas (see Relevant Specs attachment), and the SWMP (see the SWMP attachment).
9.2.2 Reclamation Bond
(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 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;
Reclamation and associated bonding requirements are covered by and have been met through
COGCC regulations. The County will need to make the determination if additional bonding is
required for the temporary disturbance of the 0.86 acre PWMS site.
9.2.3 Impact Mitigation /Standards Compliance
(C) Impacts set forth in the impact statement and compliance with the standards
contained in Section 5.03.08 of this Resolution. (A. 93 -061)
Mitigation and compliance measures for the proposed project are provided in Section 9.3.
9.3 Industrial Performance Standards Applicable to the Proposed Project
5.03.08 Industrial Performance Standards: All industrial operations in the County shall comply
with applicable County, State, and Federal regulations regulating water, air and noise pollution
and shall not be conducted in a manner constituting a public nuisance or hazard. Operations shall
be conducted in such a manner as to minimize heat, dust, stroke, vibration, glare and odor and
all other undesirable environmental effects beyond the boundaries of the property in which such
uses are located, in accord with the following standards;
The proposed project has been evaluated to determine compliance with all applicable County,
State, and Federal regulations. The following details specific areas of concern.
9.3.1 Sound
(I) Volume of sound generated shall comply with the standards set forth in the Colorado
Revised Statutes at the time any new application is made. (A, 93-061)
As discussed in Section 9.1.2 noise sources at the proposed PWMS would be limited to
the temporary generator, general truck traffic, material handling, and limited amounts of
maintenance activities and small scale fabrication. This area would be classified as light
industrial under the Colorado Revised Statute 25 -12 -103, which has allowable noise
levels of 70 decibels [db(A)] from 7:00 AM to 7:00 PM and 65 db(A) from 7:00 PM to
7 :00 AM. Material handling and general vehicle noise often generates short-term loud
noises but these would be well within the allowable limits specified by the statute [up to
10 db (A) above the allowable Tight industrial limits for up to 15 minutes of any one
hour period].
Olsson Associates / Cordilleran generated a letter report of expected noise levels
generated by an on -site generator located at the CPF (see Noise Assessment Study
Doc. No.: PBSR- ALL-RGL- PMT -URS- 000000 - 00004 -00, Rev. 0 Produced Water Management System - Special Use Permit
Chevron North American Exploration and Production Company 16 Piceance Basin Natural Gas Development Program.
attachment). The analysis indicated that the operation of the CPF generator would not
exceed the light industrial standards. It is anticipated that the noise emitted from the
temporary generator at well pad 35 -BV would be significantly less than that from the
CPF generator, and therefore, also would not exceed the light industrial standards. This
conclusion is supported by the following statement found in the Noise Assessment
Study: "it is anticipated that any other facilities associated with the project, such as the
operation of booster compressors in the project area and / or well drilling operations on
well pads, will generate lower sound levels than the CPF during full load operation ".
There also are no public noise receptors within several miles of the proposed project
site.
9.3.2 Vibration
(2) Vibration generated: every use shall be so operated that the ground vibration inherently and
recurrently generated is not perceptible, without instruments, at any point of any boundary line of
the property on which the use is located;
Operations that would generate vibration include the temporary generator and truck
traffic. Vibration from the generator is dampened by the system mounting and would
not be perceptible within a few feet of the unit. Truck traffic vibration is transient in
nature and would not be transmitted beyond the property boundaries.
9.3.3 Smoke and Particulate Matter
(3) Emissions of smoke and particulate matter: every use shall be operated so as to comply with
all Federal, State and County air quality laws, regulations and standards;
All vehicles / equipment are, or would be equipped with required emission control
devices and will be maintained to ensure compliance with applicable standards. There
are no public receptors within several miles of the proposed project site.
9.3.4 Heat, Glare, Radiation and Fumes
(4) Emission of heat, glare, radiation and fumes: every use shall be so operated that it does not
emit heat, glare, radiation or fumes which substantially interfere with the existing use of
adjoining property or which constitutes a public nuisance or hazard. Flaring of gases, aircraft
warning signals, reflective painting of storage tanks, or other such operations which may be
required by law as safety or air pollution control measures shall be exempted from this provision;
The proposed project would not generate noticeable emissions of heat, glare, radiation,
or fumes. There are no public receptors within several miles of the proposed project
site.
9.3.5 Storage
(5) Storage area, salvage yard, sanitary landfill and mineral waste disposal areas: (A97- 112)
No storage, salvage, sanitary landfill, or mineral waste disposal areas would be
constructed at the proposed site.

9.3.5.1 Flammable or explosive solids or gases
(A) Storage of flammable or explosive solids or gases shall be in accordance with
accepted standards and laws and shall comply with the national, state and local fire
codes and written recommendations/comments from the appropriate local
protection district regarding compliance with the appropriate codes; (A97 -112)
No flammable or explosive solid will be located at this site.
9.3.5.2 Visual Screening
(B) At the discretion of the County Commissioners, all outdoor storage facilities may
be required to be enclosed by fence, landscaping or wall adequate to conceal such
facilities from adjacent property; (A97 -112)
The facility is located in a remote portion of Garfield County along CR 211, which is
primarily accessed by personnel associated with the Program. Screening is not required
at this remote location. There are no public receptors within several miles of the
proposed project site.
9.3.5.3 Material Control
(C) No materials or wastes shall be deposited upon a property in such form or manner
that they may be transferred off the property by any reasonably foreseeable natural
causes or forces; (A97 -112)
The following measures would be implemented to keep materials and wastes from
leaving the property.
• Although no petroleum products or wastes are expected to be used during
normal operations, any of these materials that are on -site during construction
activities will be kept in a designated area that is provided with secondary
containment (part of SPCC Plan — see SPCC Plan attachment).
• Vehicles and equipment will be properly maintained to minimize oil / fluid
leaks.
Secondary containment would be installed around the ten frac tanks, tanks and pumps as
specified by regulations promulgated from the Oil Pollution Act and the Clean Water
Act. The earthen containment berm will consist of a 4 to 6 -inch thick bentonite -clay
liner that will be covered by road -base aggregate. Any spills collected in the berm will
be removed by vacuum truck or re- introduced into the frac tanks for disposal.
Specific information about the area would be provided to local fire department officials
for review. The site SPCC plan would be updated during the next scheduled plan update
to include details related to the berm (see SPCC Plan attachment).
9.3.5.4 Heavy Equipment Storage
(D) Storage of Heavy Equipment will only be allowed subject to (A) and (C) above and
the following standards: (A97 -1 12)
1. The minimum lot size is five (5) acres and is not a platted subdivision.
2. The equipment storage area is not placed any closer than 300 ft from any
existing residential dwelling.

Chevron North American Exploration and Production Company 18 Piceance Basin Natural Gas Development Program
3. All equipment storage will be enclosed in an area with screening at least eight
(8) feet in height and obscured from view at the same elevation or lower.
Screening may include berming, landscaping, sight obscuring fencing or a
combination of any of these methods.
4. Any repair and maintenance activity requiring the use of equipment that will .
generate noise, odors or glare beyond the property boundaries will be conducted
within a building or outdoors during the hours of 8 a.m. to 6 p.m., Mon. -Fri.
5. Loading and unloading of vehicles shall be conducted on private property and
may not be conducted on any public right -of -way.
Prograrn needs may periodically require the storage of heavy equipment at this location.
The lot size is greater than five acres and the closest residence is about 2.3 miles
southeast of the site. Because of the remote location and limited public access, screening
is not needed. No loading or unloading operations would occur on County roads.
9.3.5.5 Storage Area Limitations
(D) Any storage area for uses not associated with natural resources shall not exceed
ten (10) acres in size. (A97 -I12)
Any natural resource storage would be contained within the existing well pad site.
9.3.5.6 Lighting
(E) Any lighting of storage area shall be pointed downward and inward to the property
center and shaded to prevent direct reflection on adjacent property (A97 -112)
No outside lighting would be required for the proposed project
9.3.6 Water Pollution Sources
(6) Water pollution: in a case in which potential hazards exist, it shall be necessary to install
safeguards designed to comply with the Regulations of the Environmental Protection Agency
before operation of the facilities may begin. All percolation tests or ground water resource tests
as may be required by local or State Health Officers must be met before operation of the
facilities may begin.
As noted, no petroleum products or wastes are expected to be used during normal construction or
operations of the proposed temporary PWMS, any of these materials that are on -site during
construction activities will be kept in a designated area that is provided with secondary
containment (part of SPCC Plan - see SPCC Plan attachment). In addition, vehicles will be
properly maintained to minimize oil / fluid leaks.
Secondary containment for all water storage and storm water management controls would be
installed as previously described to eliminate potential pollutants from infiltrating the soils and/or
escaping into waters of the State of Colorado.
All trash generated by construction activities will be contained within the 30 -cubic yard, bear
proof containers provided and maintained by Down Valley Septic.
