GARFIELD COUNTY
BUILDING AND PLANNING DEPARTMENT
FEE SCHEDULE
Garfield County, pursuant to Board of County Commissioners (“Board”) Resolution No.
98-09, has established a fee structure (“Base Fee”) for the processing of each type of
subdivision and land use applications.
The Base Fee is an estimate of the average number of hours of staff time devoted to
an application, multiplied by an hourly rate for the personnel involved. The Board
recognized that the subdivision and land use application processing time will vary and
that an applicant should pay for the total cost of the review which may require
additional billing. Hourly rates based on the hourly salary, and fringe benefits costs of
the respective positions combined with an hourly overhead cost for the office will be
used to establish the actual cost of County staff time devoted to the review of a
particular project.
Actual staff time spent will be charged against the Base Fee. After the Base Fee has
been expended, the applicant will be billed based on actual staff hours accrued. Any
billing shall be paid in full prior to final consideration of any land use permit, zoning
amendment or subdivision plan. If an applicant has previously failed to pay application
fees as required, no new or additional applications will be accepted for processing until
the outstanding fees are paid.
Checks, including the appropriate Base Fee set forth below, must be submitted with
each land use application, and made payable to the Garfield County Treasurer.
Applications will not be accepted without the required application fee. Base Fees are
non-refundable in full, unless a written request for withdraw from the applicant is
submitted prior the initial review of the application materials.
Applications must include a Payment Agreement Form (“Agreement”) set forth below.
The Agreement establishes the applicant as being responsible for payment of all costs
associated with processing the application. The Agreement must be signed by the
party responsible for payment and submitted with the application in order for it to be
accepted.
The following Base Fees shall be received by the County at the time of submittal of
any procedural application to which such fees relate. Such Base Fees shall be in
addition to and exclusive of any cost for publication or cost of consulting service
determined necessary by the Board for the consideration of any application or
additional County staff time or expense not covered by the Base Fee, which have not
otherwise been paid by the applicant to the County prior to final action upon the
application tendered to the County.

OWNER: Joan Savage ZONING: Rural
COMPREHENSIVE PLAN: Residential Medium High (2 to <6 DU/AC)
REPRESENTATIVE: Grant Griffin , Olsson Associates
PRACTICAL LOCATION: Section 8, T?S, R94W
TYPE OF APPLICATION: Limited Impact Review
GENERAL PROJECT DESCRIPTION
This site is located west of County Road 350 and bisected by a road that is labeled County Road
329 on Garfield County's ArcMap. The Applicant is trying to clarify whether this road is truly a
County Road . The site is existing and situated within a 663 acre parcel owned by Joan L. Savage.
The subject site currently contains two compressors, two atmospheric (liquid) tanks, and associated
pipelines . Olsson Associates indicated that the existing pipelines were never reviewed by the
County since they didn't trigger the Pipeline Development Plan Review process. On the other
hand, the two existing compressors and tanks required a County permit and are presently
considered illegal. The Applicant wishes to obtain permits for the existing facility along with four
additional compressors. New pipelines will be proposed in conjunction with the new compressors
but it is anticipated that these pipelines will not trigger the pipeline permit process .
No on-site storage is proposed. The compressor station will be unmanned with approximately two
visits per day for inspection/maintenance and data collection . It is anticipated that a water truck will
visit the area every few weeks for dust abatement.
There are no existing gas wells on the compressor pad and gas that is received at the site is from
wells in the surrounding area .
The approval process for the existing and new compressor stations will need to be processed
through a Limited Impact Review and obtain approval of a Land Use Change Permit for the Board
of County Commissioners . Standards for Industrial Uses (Section 7-810) will apply to development
of this site. Other items to be addressed (but not limited to) in a future application include: noise,
drainage, spill prevention, stormwater management, air quality, traffic, and wildlife impacts.

Project Description
As detailed in this application, Noble Energy Inc. (Noble) is requesting a Land Use Change approval for
the Noble Rulison Compressor Station. All applicable sections of the Garfield County Unified Land Use
Resolution 2008 as Amended have been addressed, and are located throughout the application,
including the Land Suitability Analysis, Impact Analysis, and Standards Narrative.
The Compressor Station is located approximately 3.5 miles southeast from the Rulison community at
an elevation of 6,740 feet There are two existing compressors, and the applicant is requesting four
additional compressors in order to accommodate Noble’s natural gas activities. The existing
compressors were constructed in 2008 and 2009. Additional compressors are needed to facilitate the
growth of Noble’s natural gas extraction in the surrounding area. All six compressors will be
complimentary and generate the same amount of noise.
The location and property ownership of the facility are provided in the following table:

PM Joan L. Savage 240508400024
This property is located within the Rural (R) zone district and is not within a platted subdivision.
Compressor stations are an allowed use in the subject zone district, provided a Limited Impact Review
is approved. The proposed facility meets all applicable standards for the Rural zoning district. The
adjacent properties are primarily undergoing oil and gas development and have limited residential and
agriculture operations. Due to the location of the facility, the expansion will have a minimal impact, if
any, to the surrounding area. Existing topography and hospital grade mufflers will limit sound impacts
in order to meet Garfield County and Colorado Revised Statue noise standards.
Surface disturbance at this location will be minimal. There will be no additional disturbance associated
with the addition of the four compressors. An area-wide Stormwater Management Plan (SWMP),
detailing the use of site-specific Best Management Practices (BMPs) associated with Noble’s
construction activities will be utilized for the proposed project. Implementation of the SWMP will ensure
that activities conducted at the site comply with stormwater management regulations as required by
Garfield County, the State of Colorado, and the United States Environmental Protection Agency.
Through this plan, disturbed soils will be reseeded to regain stability as soon as practical, and BMP’s
will be utilized to mitigate sediment erosion and transportation. Implementation of these plans also
ensures that installation and operation of this facility will not impact surface runoff, stream flow, or
groundwater.
The existing 20’’ pipeline connects the Rulison Compressor Station to the Savage #8-(11/12/21) Pad
Site, which is operated by Noble Energy Inc. The existing pipeline is approximately 5,500 feet long.
Once the proposed compressor station is constructed and operating at full build-out (six compressors),
approximately 500 feet of pipe will be required. The additional pipelines will not warrant a Pipeline
Development Plan. All grading permits will be obtained before the commencement of construction.
This location will be accessed from Garfield County Road (CR) 350. The proposed operations will
generate approximately five (5) light vehicles per week for maintenance/monitoring purposes. No new
accesses or auxiliary lanes onto a County or State roadway will be required as indicated in the Traffic
Study.
This facility will be in operation for approximately thirty (30) years, the expected lifespan of the
associated gas wells in the area. When the facility is no longer needed to support operation of the
wells in the area, this site will be reclaimed by removing all surface equipment and structures, grading
to restore original contours, replacing any topsoil that may have been removed, and revegetating the
reclaimed area with the applicable seed mix. See Reclamation Plan for further information.
Potential impacts to wildlife, natural environment, and the surrounding properties are expected to be
minimal, if any. The proposed facility will be located on an existing disturbed area. The remote location
of this facility and the type of operations which will occur should eliminate the majority of the impacts
required to be addressed in this application. No smoke, vibration, heat, radiation or fumes will be
produced as a result of the operation of this facility. The topography surrounding the facility acts as a
visual and sound barrier in most directions, and the facility will be partially visible from surrounding
properties and public roads. Adjacent properties will not be affected by the operations, and a public
nuisance or hazard will not be created.

Land Suitability Analysis
Article IV, 4-502 D.1. Public Access
This location will be accessed from Garfield County Road (CR) 350. According to the Garfield
County GIS Database, CR 329 crosses the subject property. However, Wyatt Keesbery,
Garfield County Road and Bridge, has indicated that CR 350 is a non-maintained roadway and
public road right-of-way does not exist. Road and Bridge will address this during the review
phase of the Limited Impact Review. No new accesses or auxiliary lanes onto a County or
State roadway will be required as indicated in the Traffic Study.
Article IV, 4-502 D.2. Access to Adjoining Roadways
Access to the subject property is from County Road 350. County Road 329 intersects with
County Road 350 approximately 1,600 ft. northeast from the compressor facilities. The
proposed compressors will not adversely impact adjoining roadways due to the anticipated low
operational traffic volumes. See Traffic Analysis for further information.
Article IV, 4-502 D.3. Easements
All easements within the vicinity of the project area are described in the provided deed. The
proposed compressor station will not impact existing easements located on the subject property.
The Surface Use Agreement has been included in this application.
Article IV, 4-502 D.4. Topography and Slope
The Compressor Station will be located on an existing pad site with an approximate 0-2% slope.
There are minimal topography issues in the surrounding area. See Site Plan for further
information concerning the site’s topography.
Article IV, 4-502 D.5. Natural Features
The project area is located within a relatively flat portion of the subject property. The significant
natural features located in close proximity to the project area are the Cache and Spruce Creeks.
BMP’s will be utilized during construction and operational phases to prevent potential impacts
from run-off activity.
Article IV, 4-502 D.6. Drainage
Due to the limited footprint of the facility, no natural drainage features will be impacted by the
construction or operation of the facility. Disturbance associated with the facility’s construction
and operations will be addressed by the area-wide Stormwater Management Plan.
Article IV, 4-502 D.7. Water
The proposed facility will not use domestic water.
Ar ticle IV, 4-502 D.8. Floodplain
The project site is not located within a floodplain.
Article IV, 4-502 D.9. Soils
According to information prepared by the Natural Resources Conservation Service (NCRS),
soils in these sections have been mapped as the Morval-Tridell complex, and Vale silt loams.
The Morval-Tridell complex consists of dominantly shallow to deep, well drained soils, on mesas
and alluvial fans. The Villa Grove-Zoltay loams complex consists of deep, well drained,
moderately sloping soils on mesas, and alluvial fans. The underlining soils will not significantly
affect the compressor’s foundation or associated equipment/structures. A copy of a Custom
Soil Resource Report and the Geologic and Soils Hazard Report is included under the
supplemental material tab.
Article IV, 4-502 D.10. Hazards
No geologic hazards have been mapped by Garfield County in this area and no faults or other
hazards are evident on the Geologic Map of Colorado. No other hazards have been observed
by Noble Energy Inc.
Ar ticle IV, 4-502 D.11. Natural Habitat
The Wildlife Assessment concluded that the facility will not create hazardous attractions to avian
or mammalian wildlife species, vegetation, block migration routes, or cause a change in habitat
use. No impacts to federally listed or locally significant plant or animals are anticipated. The
proposed Compressor Station will have a minimal impact, if any, to the surrounding flora and
fauna; the Reclamation Plan has addressed the restoration of the site to pre-facility conditions
by re-contouring and re-vegetating.
Article IV, 4-502 D.12. Resource Areas
Given the limited construction activity and small footprint of the proposed facility, no protected or
registered archaeological, cultural, paleontological or historic resources will be impacted. See
the Cultural Resources Report for additional details.

Article IV, 4-502 E.2. Adjacent Uses
The adjacent uses primarily consist of agricultural, natural gas extraction, and residential
activities. The surrounding properties will not be adversely impacted by construction and
operation of the additional compressors. The operator is not aware of complaints or adverse
impacts from the existing two compressors.
Article IV, 4-502 E.3. Site Features
The project area lies south of the Colorado River on Helms Mesa. The terrain is mostly rolling
hills and large mildly sloping benches bisected by small tributaries to the Colorado River
2
including Cache Creek, Cottonwood Creek, and Spruce Creek. The elevation at the proposed
site is approximately 6,740 feet above sea level. The Compressor Station will not affect the
surrounding vegetation and water resources. No major geologic hazard exists in the immediate
vicinity of the proposed facility due to the area being well drained with a low frequency of
flooding.
Article IV, 4-502 E.4. Soil Characteristics
According to information prepared by the Natural Resources Conservation Services (NCRS),
soils in these sections have been mapped as the Morval-Tridell complex, and Vale silt loams.
The Morval-Tridell complex consists of dominantly shallow to deep, well drained soils, on mesas
and alluvial fans. The Villa Grove-Zoltay loams complex consists of deep, well drained,
moderately sloping soils on mesas, and alluvial fans. The underlining soils will not significantly
affect the compressor’s foundation or associated equipment/structures. A copy of a Custom
Soil Resource Report and the Geologic and Soils Hazard Report is included under the
supplemental material tab.
Article IV, 4-502 E.5. Geology and Hazard
The Piceance Basin is the major structural geologic feature in the region. It is bound to the east
by the Grand Hogback monocline approximately 10 miles away, the White River Uplift to the
northeast, the Gunnison Uplift to the south, and the Uncompahgre Uplift to the southwest, the
Douglas Creek Arch to the west-northwest and the axial basin uplift to the north. The geology
poses a low risk of corrosion to concrete; therefore, the soils are suitable to the proposed
construction. No geologic hazards have been mapped by Garfield County in this area and no
faults or other hazards are evident on the Geologic Map of Colorado. No other hazards have
been observed by Noble Energy Inc. (Noble).
Article IV, 4-502 E.6. Effects on Exiting Water Supply and Adequacy of Supply
Construction and operation of the compressor station will not require access to water supplies in
the area. As a result, the proposed compressor station will not adversely impact existing water
supplies in the area.
Article IV, 4-502 E.7. Effects on Groundwater and Aquifer Recharge Areas
The proposed compressor station will require minimal surface disturbance and will not adversely
impact groundwater supplies or aquifer recharge areas.
Article IV, 4-502 E.8. Environmental Effects
The proposed Compressor Station will have a minimal impact, if any, to the surrounding flora
and fauna; the Reclamation Plan (see below) has addressed the restoration of the site to pre-
facility conditions by re-contouring and re-vegetating. The Class I Cultural Resources Study
concluded that no significant archaeological, cultural, or historical resources will be affect by this
development. The Wildlife Assessment concluded that the facility will not create hazardous
3
attractions to avian or mammalian wildlife species, vegetation, block migration routes, or cause
a change in habitat use. No impacts to federally listed or locally significant plant or animals are
anticipated. No potential radiation hazards have been identified. The SPCC plan has been
developed for this facility and covers all necessary control and counter measures.
Article IV, 4-502 E. 9. Traffic
During the operational phase, there will be an average of 5 light vehicles accessing the site to
maintain/monitor the facility on a weekly basis. Due to the limited impacts of traffic generated
by the proposed use, improvements to the County Road will not be required. The proposed use
will not increase traffic by 20% on any County or State roadway or intersection. See Traffic
Study for further information.
Article IV, 4-502 E.10. Nuisance
According to the Sound Level Study and Analysis, the noise level will not exceed the
Residential/Agricultural/Rural Zone Standards and Colorado Noise Statue 25-12-103
requirements. Adjacent lands will not be impacted by the generation of vapor, dust, smoke,
glare or vibration.
Article IV, 4-502 E.11. Reclamation Plan
Reclamation Plan
Noble estimates that the proposed Compressor Station will be in operation for an anticipated
period of approximately thirty (30) years during development and production of Noble’s Garfield
County operations. Upon termination of the development and production activities, the disturbed
site will be reclaimed, as outlined below:
• All equipment and structures will be removed.
• Noble will remove all safety and storm water BMPs, and other surface objects from the
premises.
• Noble will restore the site to pre-facility conditions by re-contouring and re-vegetating the
site. Top soil will be redistributed across the site and will be reseeded with an approved
seed mix (see attached seed mix recommendation).
• Noble will monitor the site to ensure that 70 percent of the pre-existing vegetation is
achieved.
Seedbed Preparation and Slope Reconstruction:
Cut and fill slopes will be backfilled and re-contoured to a slope of 3:1 – 2.5:1 or less in
instances where necessary to match the existing natural contours. Following final contouring, all
backfilled or ripped surfaces will be covered evenly with topsoil. Re-contouring should form a
complex slope with heavy pocking. In areas with slope greater than 3 percent, imprinting of the
seed bed is recommended. Final seedbed prep will consist of scarifying/imprinting the topsoil
4
prior to seeding. Imprinting can be in the form of dozer tracks or furrows perpendicular to the
direction of slope. When hydro-seeding or mulching, imprinting should be done prior to seeding,
unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing,
imprinting will be done as part of the harrowing. Furrowing can be done by several methods, the
most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed.
Other simple imprinting methods include deep hand raking and harrowing, always perpendicular
to the direction of slope. All compacted areas will be ripped to depth of 18” with max furrow
spacing of 2’. Where practicable, ripping will be conducted in two passes at perpendicular
direction.
Topsoil: Following final contouring, all backfilled or ripped surfaces will be covered evenly with
topsoil. The topsoil in the cut slope on the back of the pad will be heavily pocked using the
excavator bucket to form an uneven soil surface complex which will aid in revegetation and help
with slope stabilization. The fill slope, and remaining disturbed, and reclaimed areas will be track
walked to aid in revegetation and slope stabilization. In areas that may not have been disturbed
during the reclamation process or areas of suspected compaction that will be reseeded,
measures will be taken to loosen and spread the topsoil. These measures may include
scarifying the soil by racking or harrowing the soil.
Seed Mix: Seed mix used for reclamation will be taken from the approved seed mixtures
identified below:
5
6
Seeding Procedures: For best results and success, the recommended grass mixture reseeding
should be done in late autumn in order to take advantage of natural precipitation for the region.
The reseeding rate should be doubled for broadcast application. Preferred seeding method is
multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and
imprinting and waterbars, where applicable.
Alternative seeding methods include, but are not limited to:
• harrow with just enough soil moisture to create a rough surface, broadcast seed and
reharrow, preferably at a 90 degree angle to the first harrow;
• hydro-seeding (most economical in terms of seed cost); and
• hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking.
• These are not the only means of replanting the site. However, these methods have been
observed to be effective in similar landscapes.
The prepared soils will be seeded (weather permitting) no more than 24 hours following
completion of final seedbed preparation. The seeding will be conducted by means of drilling the
prescribed seed at prescribed seeding rate. The seed will be drilled with a common range drill at
a depth of 0.25 – 0.5” beneath the soil surface. The seed will be drilled horizontally across the
pad faces and perpendicular to the track walking when possible. When slope gradient less than
2.5:1 exists and drilling is not possible from a mechanical and safety standpoint the soils will be
broadcast seeded at twice the prescribed amount. The reseeding will be monitored and
reseeded as appropriate until the reclamation standards detailed above are met.
Mulch: With 24 hours of reseeding (weather permitting) hydromulch will be applied to all
reclaimed and reseeded surfaces. Areas where the erosion potential is such that biodegradable
blankets will be used will not be hydromulched.

Introduction
Noble Energy has proposed a compressor station that will be located on an existing Noble
Energy pad. This pad is located in Section 8, Township 7 South, Range 94 West, of the Sixth
Principal Meridian, and is located to the southeast of the town of Rulison, and south of Interstate
70, and the Colorado River, in Garfield County Colorado (Figure 3).
The Noble Energy compressor station project is located basically on the eastern edge of the
Piceance Basin near the Grand Hogback and consists of 2,200 acres. It lies adjacent to areas
undergoing natural gas development by Williams Production RMT. The natural gas resources
that are being developed lie within the Cretaceous age Williams Fork Formation and Mancos
Shale. The proposed location is:
• SE ¼ Section 8, T7S, R94W.
Geology
The proposed compressor station project is located near the eastern margin of the Piceance
Basin; an irregularly-shaped elongated basin formed by tectonic forces that downwarped the
earth’s crust as a result of the uplift of the Colorado Rocky Mountains. Areas on all sides of the
Piceance Basin have been uplifted by these same tectonic forces.
Structural Geology
The Piceance Basin is the major structural geologic feature in the region. It is bound to the east
by the Grand Hogback monocline approximately 10 miles away, the White River Uplift to the
northeast, the Gunnison Uplift to the south, and the Uncompahgre Uplift to the southwest, the
Douglas Creek Arch to the west-northwest and the axial basin uplift to the north (Grout and
Verbeek, 1992).
The Grand Hogback monocline is a sinuous feature comprised of Upper Cretaceous age
bedrock of the Mesaverde Group, which includes the Williams Fork Formation and the
underlying Mancos Shale. The Grand Hogback forms part of the boundary between two major
physiographic provinces, the Colorado Plateau and the Rocky Mountain foreland. The Grand
Hogback bends abruptly to the north of the Gibson Gulch Quadrangle and strata along the west-
to southwest-facing, steep limb of the monocline typically dip basinward at an angle of 45° or
are even overturned in some areas (Grout and Verbeek, 1992). A series of west-northwest
trending, broad, gentle anticlines and synclines, are present within the Piceance Basin to the
west of the Grand Hogback. The Wolf Creek Anticline and the Divide Creek Anticline are the
two closest of these structures.

Surficial Geology
A copy of a NCRS Custom Soil Resource Report for the project site has been provided under
the supplemental material tab for Planning Staff review. The location for the proposed
compressor station is underlain by undivided Quaternary, landslide deposits, consisting of sand,
silt, clay and gravel (Figure 1). Primary soil is sand; secondary silt, followed by clay, mud and
gravel. These are the major soils that occur at this location. The Geological Hazards report
provides a soils map (Figure 2) for the location of the proposed facility. This location is
underlain by soils of the Morval-Tridell complex, 6 to 25% slopes (soil unit 45 on Figure 2) and
Vale silt loam, 12 to 25 % slopes (soil unit 70 on Figure 2). This soil unit is a well drained soil
that is typically more than 80 inches thick.
No major geologic hazard exists in the immediate vicinity of the proposed facility due to the area
being well drained with a low frequency of flooding.
Soils
According to information prepared by the Natural Resources Conservation Commission Soil
Survey soils in these sections have been mapped as the Morval-Tridell complex, and Vale silt
loams. The Morval-Tridell complex consists of dominantly shallow to deep, well drained soils, on
mesas and alluvial fans. The Villa Grove-Zoltay loams Complex consists of deep, well drained,
moderately sloping soils on mesas, and alluvial fans. The proposed project location lies in
areas where the following soil types are predominant:
• SE ¼ Section 8, T7S: R94W : Morval-Tridell complex, 6 to 25% slopes (Unit 45);
• SE ¼ Section 8, T7S, R94W : Vale silt loams 12 to 25 % slopes (Unit 70)
Morval-Tridell complex complex make up about 75 to 80 percent of the above complexes. The
Morval-Tridell soils have parent materials of reworked alluvium derived from sandstone and/or
reworked alluvium derived from basalt. These soils have a landform setting of mesas and
alluvial fans with slopes of 6 to 25 percent. Elevations range from 6,500 feet to 8,000 feet
above mean sea level. Morval-Tridell complex soils are generally clayey to loamy and contain
variable amounts of gravel, cobbles and stones. The surface is normally covered with stones
weathered from the high-lying rock outcrop. South of the Colorado River, stones and cobbles
of basalt are found on the surface. Some areas are covered with basaltic boulders and stones.
The erosion hazard is low due to the linear geology of the vicinity.
Vale silt loam soils are developed on 12 percent to 25 percent slopes, and consist of deep well
drained, gently sloping to rolling soil on mesas and the valley sides. Elevations range from
5,000 feet to 7,200 feet above mean sea level. These soils formed in reworked alluvium derived
from basalt and sandstone. Permeability and available water capacity are moderate. Surface
runoff is slow, and erosion hazard is slight.
Soil Hazards
Location Soil Hazard
Morval-Tridell complex, 6 Erosion SE Y. Section 8, T7S, R94W to 25 percent slopes Hazard Low (Unit 45)
SEY. Section 8, T7S, R94W Vale silt loam, 12 to 25 Erosion
percent slopes (Unit 70) Hazard Low
Olsson appreciates the opportunity to provide this information to Noble Energy pertaining to the
assessment of geologic and soil hazards associated with the proposed compressor station
location in Garfield County, Colorado. Olsson can conduct field work to assist Noble Energy
with the site specific assessments of the proposed communication tower location, roads, and
pipeline easements to determine the degree to which these hazards may affect the specific
locations.
Special siting, geotechnical testing, engineering controls, and stability analyses may be required
to complete the construction of these locations. If you have any questions or comments, please
contact me at (970) 263-7800.

Subject: Rulison Compressor Station Sound Level Study and Analysis
At the request of Noble Energy Inc (Noble), Olsson Associates (Olsson) has completed a sound
level study and analysis for the proposed expansion of the Rulison Compressor Station located
approximately 3.5 miles southeast of Rulison, CO.
Sound readings were collected on March 11, 2011 between the hours of 10:30 a.m. and 12:00
p.m. and on March 23, 2001 between the hours of 10:00 am and 2:00 pm for the sound level
study. Sound measurements were collected using a calibrated RION NL-21 sound level meter
set to collect general sound measurements (dB(A)). In accordance with Rule 802 of the
Colorado Oil and Gas Conservation Commission (COGCC) Rules and Regulation, entitled
“Noise Abatement”, sound measurements were collected each minute for 15 minutes and then
averaged. Winds speeds were measured with a Brunton ADC wind meter and were mostly
calm or very light (less than 5 mph). All measurements were taken at a distance of 4 feet from
the ground.
Sound Level Survey:
A total of 8 locations were surveyed with four of the locations being at the nearest property line
to the north, south, east, and west. The remaining four locations were approximately following
the north, south, east, and west quadrants of the compass at a distance of 350’ form the noise
source. Sound measurements ranged between 50.0 dB(A) and 52.2 dB(A) at 350’ and 33.7
dB(A) and 46.3 dB(A) at the property line. Table 1 below shows the 15-minute average at each
location.

A map identifying the sample locations and sound level averages is provided as Figure 1. The
individual measurements, averages at each location, and representative graph are provided as
Attachment 1.
Sound Level Analysis:
Along with the sound level study, a sound level analysis of potential sound impact has been
completed for the Rulison Compressor Station. The sound generating equipment that will be
associated with the facility is a total of 6 compressor units. The units are identified as Existing,
Proposed Compressors #1, and Proposed Compressors #2. Each unit consists of 2
compressors and associated equipment located inside building structures. Since all of the
equipment has not been installed, this analysis was prepared based on data collected during
the sound survey form the existing unit. It is assumed that the sound level generated by the
Proposed Compressors #1 and #2 will each be approximately equal to the measured levels
generated by the existing unit at each sample location.
The cumulative level of sound (CLN) from multiple noise sources at a given point can be
calculated using the following equation:
CLN = 10 * log10 ((10^(L1/10)+10^(L2/10)+…...+10^(Ln/10))
Where: L = sound level from a given source at the given point.
n = total number of noise sources
Sound level estimates range between 54.8 dB(A) and 56.9 dB(A) at 350’ and 38.5 dB(A) and
51.1 dB(A) at the property line. Table 2 below shows the estimated total sound level at each
sample location.

A map identifying the sample locations, sound-generating equipment locations, and estimated
sound levels is provided in Figure 2. The calculations for the estimated levels at each location
are provided in Attachment 2.
Rulison Compressor Station Sound Level Study and Analysis Page 3 of 3
Summary:
According to COGCC Residential/Agricultural/Rural Zone standards, the threshold levels are
55 dB(A) from 7:00 am to 7:00 pm at 350’ from the noise source or at the property boundary,
whichever is greater.
Colorado Noise Statute 25-12-103 for Residential standards, the threshold levels are 55 dB(A)
from 7:00 am to 7:00 pm at twenty-five (25) feet past the property line.
Based on the information provided above, it is reasonable to expect that the operation of the
equipment at the Rulison Compressor Station, between the hours of 7:00 am and 7:00 pm, will
not exceed the applicable COGCC standards at the property boundaries.

SECTION 3.0 INTRODUCTION
In January of 1974, the Environmental Protection Agency (EPA) adopted 40 CFR Part 112 as
the Oil Pollution Prevention Program, which was most recently amended on December 5, 2008.
These oil pollution prevention regulations require the preparation of a Spill Prevention Control
and Countermeasure (SPCC) Plan for facilities engaged in drilling, producing, gathering,
storing, processing, refining, transferring, distributing, using, or consuming oil and oil products,
and which due to their location, could reasonably be expected to discharge oil in harmful
quantities into or upon the navigable waters of the United States (40 CFR, Part 112.1(b)). The
SPCC regulations and additional information can be found at:
http://www.epa.gov/oilspill/spcc.htm.
The following sections of this plan are presented in the sequence of the SPCC rule, as required
by the rule. The substantive requirements (§112.7 and §112.9) are addressed in Sections 6
and 8, respectively. Throughout this plan, where applicable, references to the appropriate
subsections of 40 CFR Part 112 are provided, followed by an explanation of how the
requirements have been addressed.
4
SECTION 4.0 GENERAL APPLICABILITY
The Oil Pollution Prevention Regulations (40 CFR Part 112) require preparation of an SPCC
plan for facilities that have discharged or could reasonably be expected to discharge oil into or
upon navigable waters of the United States or adjoining shorelines. Specifically, §112.1(d)(2)
requires an SPCC plan to be developed for facilities where the buried below ground storage
capacity of oil is greater than 42,000 gallons or the aggregate aboveground storage capacity of
oil is greater than 1,320 gallons (inclusive of containers with thresholds of 55-gallons or greater).
Because the Piceance Area Production Unit near Parachute and Rulison, Colorado has a
collective potential maximum above ground storage capacity above the threshold amount,
Noble is required to develop, implement, and maintain an SPCC plan for this facility.
The purpose of this SPCC plan is to identify sources of oil at the Piceance Area Production Unit
and outline procedures to prevent the release of oil to navigable waters of the United States.
A release of oil is considered a discharge under this plan only if the release is into or upon the
navigable waters of the United States, adjoining shorelines, or waters contiguous with the
navigable waters of the United States. This is apparent if a release impacts surface water
quality by causing a film, sheen or discoloration of the water surface or adjoining shorelines, or
causes a sludge or emulsion to be deposited beneath the surface of the adjoining shorelines.
Impacts to groundwater also apply if the groundwater is contiguous with navigable waters of the
United States (i.e., groundwater discharges to/contributes to the total volume of a surface water
body that is itself contiguous with navigable waters of the United States).
Any facility that could, because of its location, be expected to cause substantial harm to the
environment by discharging oil into or on navigable waters or adjoining shorelines is required to
prepare and submit a facility response plan (FRP) to the USEPA Regional Administrator (RA) in
accordance with 40 CFR Part 112.20. The Piceance Area Production Unit is not considered
such a facility because it does not meet any of the substantial harm criteria specified in §112.20.
These criteria, and the associated applicability determination regarding the Piceance Area
Production Unit, are shown in Appendix A. This appendix is the Certification of the Applicability
of the Substantial Harm Criteria required by §112.20 and must be maintained at the facility.
Because submittal of an FRP is not required, except at the discretion of the RA, this SPCC plan
provides information and procedures for responding to discharges.

SECTION 5.0 SPCC PLAN ADMINISTRATION: §112.3, §112.4, AND §112.5
5.1 Requirement to Prepare: §112.3
This SPCC plan was prepared to comply with the SPCC rule (40 CFR Part 112) that was most
recently amended on December 5, 2008. In accordance with §112.3(a) and the most recent
compliance timeline extension announced by the EPA, this plan was completed prior to and will
be fully implemented prior to November 10, 2010.
In accordance with §112.3(e)(1) and (2), a complete updated copy of the SPCC Plan and
associated files will be maintained at the facility, and at the Noble district office in Denver,
Colorado. During normal working hours at the facility, the plan will be available to authorized
representatives of Local, State or Federal governing agencies for on-site review and a copy will
be submitted to the EPA if requested.
5.2 Amendment by Regional Administrator: §112.4
In accordance with §112.4(a), whenever more than 1,000-gallons of oil have been discharged in
a single incident or more than 42-gallons of oil have been discharged in each of two incidents
over a 12-month period, Noble will submit a report to the EPA RA within 60 days (refer to the
definition of a discharge previously provided in Section 4). The report must include the
following:
• §112.4(a)(1): Name of the facility;
• §112.4(a)(2): Name of the operator;
• §112.4(a)(3): Location of the facility;
• §112.4(a)(4): Maximum storage or handling capacity of the facility and the normal daily
throughput;
• §112.4(a)(5): Corrective action and countermeasures that have been taken, including a
description of equipment repairs and replacements;
• §112.4(a)(6): An adequate description of the facility, including maps, flow diagrams, and
topographical maps, as necessary;
• §112.4(a)(7): The cause of such discharge as described in 40 CFR 112.1(b), including a
failure analysis of the system or subsystem in which the failure occurred;
• §112.4(a)(8): Additional preventive measures taken or planned to minimize the
possibility of recurrence; and
• §112.4(a)(9): Such other information as the Regional Administrator may reasonably
require pertinent to the SPCC Plan or discharge.
6
In accordance with 40 CFR 112.4(c), copies of the incident report will also be forwarded to the
representative/case manager designated by the appropriate local or tribal agency. Should the
RA subsequently propose by certified mail or personal delivery that this SPCC plan be
amended, in accordance with §112.4(e) Noble will:
• Submit arguments and supporting information in response to the proposed amendments
within 30 days; or
• Amend this SPCC plan within 30 days and implement the amended plan within six
months, unless otherwise authorized by the RA.
5.3 SPCC Plan Amendment by Owner/Operator: §112.5
In accordance with §112.5(a), when there is a change in facility design, construction, operation,
or maintenance that materially affects the facility’s potential for a discharge, Noble will amend
this SPCC plan within six months of the change and implement the amended plan within six
months of its completion. Modifications which may require plan amendments and certification
include:
- Commissioning or decommissioning of containers or oil-filled equipment
- Replacement, reconstruction, or movement of containers or oil-filled equipment
- Reconstruction, replacement, or installation of piping systems
- Construction or other work that alters secondary containment structures
- Changes in stored materials or type of equipment service
- Changes in operating and maintenance procedures that affect SPCC compliance.
In accordance with §112.5(b), Noble will also review this plan at least once every five years from
the date of the last review. As a result of the review, the plan will be amended within six months
of the review if more effective prevention and control technology has been field-proven at the
time of the review and will significantly reduce the likelihood of a discharge. The amended plan
will be implemented within six months of its completion. The designated person accountable for
oil spill prevention at the facility (the Environmental Coordinator, see Section 6.1) will document
completion of each five year review, sign a statement as to whether the plan will be amended,
and record the results in Appendix B.
As required by §112.5(c), technical amendments to the plan will be certified by a Professional
Engineer. Any such amendments to this SPCC plan shall be noted on the Amendment Log
included in Appendix B of this SPCC plan. Entries into the log will indicate a general
description of the changes that were made to the facility, the corresponding changes that were
made to the SPCC plan, including plan section and page numbers, and the name and signature
of the person making the changes. A new certification page will be signed, sealed and inserted
into this plan to complete the amendment process.
Non-technical changes include, but are not limited to, such items as: contact lists, more
stringent requirements for stormwater discharges to comply with NPDES rules, phone numbers,
product changes if the new product is compatible with conditions in the existing tank and
secondary containment materials, and any other changes which do not materially affect the
facility’s potential to discharge oil. If Noble personnel are unsure whether the amendment is
technical or non-technical, the amendments should be reviewed and certified by a Professional
Engineer.

6.2 General Facility Description
The Piceance Area Production Unit is comprised of natural gas production well sites and
associated pipeline systems owned and operated by Noble Energy, Inc.. The facility is located
in western Colorado, in Mesa and Garfield Counties. The area surrounding the facility is
considered multiple-use land and area activities include oil and gas exploration and production.
The locations of the facilities and details of the individual sites and oil storage areas are
depicted in Appendix D.
Wallace Creek, Spring Creek, Spruce Creek, and several other unnamed ephemeral drainages
are located in the area of the Piceance Area Production Unit. All existing drainages in the
vicinity of the facility discharge to the Colorado River. Natural drainage varies with site location.
The well locations are typically graded flat level and cover a large area in relation to storage
tank areas. Downhill slope direction arrows on the site maps in Appendix D indicate the
predicted general direction of storm water flow at each site.
The facility consists of metering equipment, dehydration, separation, and processing equipment,
above ground storage tanks, and piping systems. Products related to the maintenance and
operation of the facility are stored in above ground storage tanks. Natural gas liquids are
occasionally taken from the facility via tank truck. The facility operates 24 hours per day and is
continuously manned by operations personnel. An inventory of all storage tanks at the facility is
provided in Section 6.5. Specific liquids stored at the facility are considered oils, as defined in
40 CFR §112.2, for the purpose of this SPCC plan. The facility is considered a production
facility and is hence subject to the specific SPCC requirements of 40 CFR §112.9 for onshore
production facilities.
6.3 SPCC Plan Conformance and Deviations: §112.7(a)(1) and (2)
This SPCC plan is intended to conform to the applicable requirements of CFR 40 §112.7, as
detailed in the subsequent sections of this SPCC plan. The Piceance Area Production Unit is
an onshore production facility and is therefore subject to §112.9.
9
6.4 Facility Layout: §112.7(a)(3)
Oil storage areas at the facility are identified in Appendix D. There are no completely buried or
bunkered tanks at the facility, or buried pipelines related to the handling of oil as defined by
§112.2 of the SPCC regulations, other than lines leading from the separation equipment to
storage tanks. Aboveground storage containers and oil-filled equipment applicable to this plan
are listed below in Section 6.5
6.5 Oil Storage Capacity: §112.7(a)(3)(i)
A summary of the substance, containers, and container capacities applicable to this plan is
provided in the following table. Although oil-filled equipment are not considered bulk storage
containers as defined by §112.2, the applicability criteria such as oil storage capacity and
potential for a discharge still pertain and the prevention of discharges from such equipment is
covered in §112.7(k) of the SPCC rule. Consequently, the type of oil and capacity of the oil-
filled equipment at the Piceance Area Production Unit are included in the summary.

Notes: The “Required Containment Capacity” is required to contain the storage capacity of the largest
vessel in the specific containment plus at least 2.5 inches of freeboard to accommodate precipitation
associated with a 24-hour 25-year storm event. (Source: NOAA Atlas 2)
6.6 Discharge Prevention Measures: §112.7(a)(3)(ii)
The Piceance Area Production Unit relies on a number of measures to aide in the prevention of
a discharge. Descriptions of these measures are provided below.
• Routine maintenance of any oil-containing equipment is performed by trained personnel
at the location of the equipment utilizing soaker pads and the available secondary
containment structures and/or drip pans as warranted.
• Each storage tank or vessel has a system in place that has been designed and installed
in accordance with good engineering practice to prevent discharges. These features
may include: adequate containment volume to avoid overfill during normal operations,
and; high level sensors and controls to stop liquid flow. All discharge features are
inspected at regular intervals.
6.7 Discharge or Drainage Controls: §112.7(a)(3)(iii)
The products stored at the Piceance Area Production Unit (natural gas liquids, produced water,
and lubricating oil) are noncorrosive materials and are compatible with the materials with which
the storage containers and containment structures at the facility are constructed. The
containment structures at the facility are designed to provide adequate protection against the
discharge of oil. Secondary containment is provided for the atmospheric aboveground storage
tanks. Secondary containment details are provided in Sections 6.14 and 6.19.
20
Containment capacity calculations and/or specifications are provided in Appendix D. Each
secondary containment system, including the walls and floor of the respective system, is
capable of containing oil and has been constructed so that any discharge from a primary
containment system (such as a tank or pipe) will not permeate, drain, infiltrate, or otherwise
escape before cleanup occurs.
6.8 Countermeasures for Disch arge Discovery, Response and Cleanup:
§112.7(a)(3)(iv)
As part of routine facility procedures, visual exterior inspections of the oil storage containers and
equipment are made several times per week, at a minimum, for signs of deterioration or leaks.
Deficiencies noted from these examinations are entered on a check sheet and corrected in a
timely manner. Inspection check sheets are kept in a logbook in the facility office. In addition to
the regular checks, the oil storage equipment is inspected annually according to the written
procedures outlined in Section 6.16 of this plan
In the event of a release, the facility has trained personnel and equipment available to contain
and clean up minor volumes of oil. On-site equipment and materials include spill kits, shovels,
and sorbent materials (booms, pads, etc.) that may be used to dike, contain and remove minor
releases.
In the event of a larger release, specific response procedures have been developed (See
Appendix C). As part of these procedures, external resources (contractors) have been
identified to assist facility personnel. To ensure the commitment of these external resources,
Noble Energy, Inc. maintains a service agreement with each selected contractor. A list of
approved contractors is kept at the facility and at the Noble district office in Denver, Colorado.
At a minimum, contractors identified to assist in a spill response will have the capabilities to
provide emergency response, industrial power vacuuming, tank and pipeline cleaning,
equipment decontamination, excavation/earthmoving and waste transportation and disposal
services.
6.9 Recovered Materials Disposal: §112.7(a)(3)(v)
Materials recovered during a spill event will be appropriately containerized or will be remediated
on site in accordance with Colorado Oil and Gas Conservation Commission (COGCC)
stipulations. Soils and other solids will be placed in 55-gallon drums or roll-off containers, or in
other approved containers as warranted. Liquids will be placed in 55-gallon drums or will be
collected in a tank truck using industrial power vacuuming. Recovered materials will be labeled,
characterized and disposed/recycled in accordance with applicable federal, state and local
regulations.
6.10 Contact List and Notification Phone Numbers: §112.7(a)(3)(vi)
The contact list for oil spill response activities is provided in Appendix C, as part of the Oil Spill
Response Procedures developed for the Piceance Area Production Unit.
21
6.11 Reporting and Notification Procedures: §112.7(a)(4)
Reporting and notification requirements are outlined in the Oil Spill Response Procedures
provided in Appendix C.
6.12 Oil Spill Response Procedures: §112.7(a)(5)
Oil Spill Response Procedures for the Piceance Area Production Unit are provided in Appendix
C.
6.13 Discharge Analysis: §112.7(b)
Pursuant to §112.7(b), the reasonably expected modes of equipment failure or accidental fluid
release are:
- Failure modes: Corrosion, piping or valve failure, tank failure, pressure vessel
rupture, overflow, overfilling, vandalism, lightning strikes, and human error.
- Rate of discharge flow: the rate of flow of an accidental release will vary depending
on ambient conditions, the type of failure mode causing the release, the location of
the release, and the volume of material stored in the container or equipment. The
ambient temperature at the time of release can affect fluid viscosity and flow rates.
Piping or valve failures can result in flow rates ranging from 1 to several hundred
gallons per hour. Tank failures or lightning strikes can result in instantaneous
releases of entire container volumes.
- Discharge quantity: discharge quantities will vary depending on the type and location
of the failure. Tank release quantities will not exceed the storage volume of the tank.
Process equipment release quantities will be dependent on the length of time that
the release goes undetected.
- Preventative measures: Tanks and oil-filled equipment are constructed in
accordance with API, ASME, or other applicable industry standards. Where
practicable, diversionary or containment structures are in place to control or contain
released fluids as described in this document.
6.14 Spill Containment: §112.7(c)
Oil storage containers at the Piceance Area Production Unit are equipped with secondary
containment as noted in this document. Spill containment at the facility is described below:
• Secondary containment is typically provided for the lubricating oil, and condensate
above ground storage tanks in the form of earthen dikes or steel-wall containers.
Containment for the other oil-filled equipment and vessels is provided as described
below or in Section 6.19. Secondary containment deficiencies will be corrected by
November 10, 2010.
• Containment structures are, or will be, configured to contain the storage capacity of the
largest tank within the containment area, plus at least 2.5 inches of freeboard to
accommodate precipitation associated with a 24-hour 25-year storm event (Source: U.S.
Department of Commerce National Oceanic and Atmospheric Administration Atlas 2,
Volume II). The containment volume calculations associated with the secondary
containment structures are presented in Appendix D.

No discussions related to practicability are warranted because this SPCC plan either does not
deviate from the requirements of §§112.7(c), 112.7(h)(1), 112.8(c)(2), 112.8(c)(11), 112.9(c)(2),
112.10(c), 112.12(c)(2), and 112.14(c), or, where it does deviate, the deviations are not
practicability-caused issues.
6.16 Inspections, Tests and Records: §112.7(e)
Oil storage containers, oil-filled equipment and related containment structures at the Piceance
Area Production Unit are visually examined several times per week, at a minimum, for signs of
deterioration or leaks. These inspections are conducted as part of normal facility operations.
Deficiencies noted from these examinations are entered on a check sheet and corrected in a
timely manner. The equipment is also inspected annually according to the written procedure in
Appendix E.
Signed and dated records of all inspections and other pertinent information, such as spills,
removal and disposal of spill contaminated materials, replacement or repair of equipment, and
training are maintained for a minimum of 3 years.
6.17 Personnel Training and Discharge Prevention Measures: §112.7(f)
Oil-handling personnel operating the facility are required to have training in the operation and
maintenance of equipment to prevent the discharge of oil; discharge procedure protocols;
applicable pollution control laws, rules, and regulations; general facility operations; and the
contents of the facility SPCC plan. They are under the direct supervision of the Environmental
Coordinator, who is responsible for establishing performance and duty guidelines and is the
designated person accountable for spill prevention at the facility. Regular safety meetings are
held to discuss a variety of safety procedures and other pertinent job responsibility criteria. A
written record of all training is maintained for 3 years.
At a minimum, training is conducted annually and whenever new spill regulations are
promulgated, existing operating systems are modified, personnel responsibilities change, or the
SPCC plan is amended. In addition, regular safety meetings will be used as a forum to
reinforce understanding of SPCC procedures as necessary. An outline of the topics to be
covered during SPCC training is presented in Appendix F. Attendance rosters and other
training records will be maintained in the main office at the facility for a period of no less than
three years.
6.18 Security: §112.7(g)
The security requirements of the SPCC rule are not applicable to the Piceance Area Production
Unit, as the facilities are production facilities.
23
6.19 Facility Tank Car and Tank Truck Loading/Unloading: §112.7(h)
The tank and tank truck loading and unloading requirements of the SPCC rule are not
applicable to the Piceance Area Production Unit, as the facilities are production facilities.
6.20 Brittle Fracture Analysis: §112.7(i)
The Piceance Area Production Unit have no field-constructed aboveground oil-storage
containers that apply to this plan and therefore this section of the regulation is not applicable.
6.21 Applicable Requirements: §112.7(j)
Sections 6 and 8 of this plan provide detailed discussions of conformance with the applicable
requirements and other effective discharge prevention used at the facility.
6.22 Qualified Oil-filled Operational Equipment: §112.7(k)
This facility uses qualified oil-filled operational equipment (i.e. equipment that include an oil
storage container in which the oil is present solely to support the function of the device and that
have not had a single discharge exceeding 1,000 gallons or two discharges exceeding 42
gallons within a twelve month period in the three years preceding this plan).
The qualified oil-filled operational equipment are included in the facility inspection program
discussed in Section 6.16 of this plan to detect equipment failure and/or discharges. An oil spill
contingency plan following the provisions of 40 CFR Part 109 has been prepared, and Section
1.0 of this plan contains a written commitment of manpower, equipment, and materials required
to expeditiously control and remove any quantity of oil discharged that may be harmful.
24
SECTION 7.0 REQUIREMENTS FOR ONSHORE (NON-PRODUCTION) FACILITIES:
§112.8
The Piceance Area Production Unit are not onshore non-production facilities. Consequently,
the provisions in §112.8 do not apply.
25
SECTION 8.0 REQUIREMENTS FOR ONSHORE OIL PRODUCTION FACILITIES:
§112.9
8.1 Oil Production Facility Drainage: §112.9(b)
Precipitation that may accumulate in any contained area is normally allowed to evaporate. No
automatic pumps or ejector devices are present in any of the containment areas. If removal of
any water accumulated in the containment areas is necessary, it will be conducted under the
direct supervision of responsible personnel as described in this section.
Accumulated precipitation is removed, when necessary, from secondary containment areas
using a vacuum truck, pump, or other appropriate method. Removed water is disposed of in
accordance with applicable local, state, and federal regulations. Prior to removal of the water
from any containment area, the responsible personnel visually inspect the water in the
containment structure and note the appearance of the water in the facility logs. The name of the
person draining the containment, as well as the date, time, and approximate quantity of water
removed will also be recorded in the facility logs and kept on file with the SPCC documents for a
period of at least three years. A secondary containment drainage log is included in Appendix
E.
The drain systems at the Piceance Area Production Unit are of the ‘enclosed’ type. All process
effluents are routed through drain lines to storage tanks. No process effluents, untreated or
treated, are released off-site.
All field drainage systems (such as drainage ditches or road ditches) in the vicinity of the facility
are inspected at regular intervals for the presence of accumulated oil that may have resulted
from a small discharge. Any accumulated oil will be removed from these areas promptly upon
discovery.
8.2 Oil Production Facility Bulk Storage Containers: §112.9(c)
The products stored at the Piceance Area Production Unit are compatible with the materials with
which the storage containers and containment structures at the facility are constructed. Specific
secondary containment details are presented in Sections 6.14 and 6.19.
Oil storage containers at the Piceance Area Production Unit are equipped with secondary
containment as noted in this document. Spill containment at the facility is described in Section
6.14 and Appendix D.
Certain secondary containment structures at the facility are constructed with native soils or road
construction-grade fill material. The composition of the native soil is considered sufficiently
impervious to contain spilled oil until cleanup operations can commence.
Oil storage containers, oil-filled equipment and related containment structures at the Piceance
Area Production Unit are visually examined several times per week, at a minimum, for signs of
deterioration or leaks. These inspections are conducted as part of normal facility operations.
Deficiencies noted from these examinations are entered on a check sheet and corrected in a
26
timely manner. The equipment is also inspected annually according to the written procedure in
Appendix E.
Each storage tank or vessel at the Piceance Area Production Unit has a system in place that
has been designed and installed in accordance with good engineering practice to prevent
discharges. These features may include adequate container volume to avoid overfill and high-
level sensors and controls to stop liquid flow. All discharge prevention features are inspected at
regular intervals.
8.3 Facility Transfer Operations, Oil Production Facility: §112.9(d)
All above ground valves and pipelines are routinely inspected for the general condition of flange
joints, valve glands and bodies, drip pans, pipe supports, and other appurtenances. Integrity or
leak testing is also performed at the time of any installation, modification, construction,
relocation, or replacement of buried piping.
The following procedures and protocols are in place to maintain all flow lines in order to prevent
discharges from flow lines:
• All buried piping at the facility is protected by coating or wrapping. Any buried
equipment will be visually inspected for corrosion whenever exposed through
excavation. Further inspection and repair will be conducted on the affected metal
equipment if problems are identified to minimize the chance for a discharge from facility
transfer equipment.
• When a pipe that has potential for re-use is not in service, or it is in a standby service for
an extended period of time, any associated valves are kept closed and locked and lines
are sealed appropriately and marked as to their tie-in connection.
• All pipe supports at the facility are designed to minimize abrasion and corrosion and to
allow for expansion and contraction. Pipe supports are routinely inspected as part of the
general facility inspections described in this SPCC plan.
27
SECTION 9.0 REQUIREMENTS FOR ONSHORE OIL DRI LLING AND WORK OVER
FACILITIES: §112.10
The Piceance Area Production Unit are not onshore oil drilling or work over facilities.
Consequently, the provisions in §112.10 do not apply.
SECTION 10.0 REQUIREMENTS FOR OFFSHORE OIL DRILLING, PRODUCTION AND
WORK OVER FACILITIES: §112.11
The Piceance Area Production Unit are not offshore oil drilling, production or work over facilities.

Oil Spill Response Procedures
1. Response Management Structure
The Spill Coordinator and Alternate Spill Coordinator(s) are responsible for implementing response
procedures in the event of an oil spill or discharge emergency. These personnel have the authority to
commit the resources necessary to carry out a response. However, all operating personnel at the
Piceance Area Production Unit receive training to familiarize themselves with all aspects of the SPCC
Plan, facility operations, the location and characteristics of materials handled at the facility, and the
location of all records within the facility; and are responsible for proper implementation of response
procedures should the Spill Coordinator or Alternate Spill Coordinator(s) be unavailable.
2. Initial Response
Releases at the Piceance Area Production Unit will be discovered through observations made during
the course of normal work activities, inspections of work areas and equipment, monitoring devices, or
by chance. Discovering a release is the first step in initiating a response. Upon discovery, the
individual discovering a release should immediately:
1. Assess the basic situation.
2. Stop the source of the release if safely possible using available resources (including spill kits).
3. Restrict ignition sources if the material is flammable.
4. Secure the area as off limits.
5. In the event that the incident poses an immediate threat of fire, explosion, or other impact to
safety, health, or the environment, contact the local fire department at 911. DO NOT HANG
UP after completing the report, let the dispatcher hang up first.
6. Report the release to the Spill Coordinator or an Alternate Spill Coordinator (see attached Oil
Spill Incident Notification Phone Numbers).
7. The Spill Coordinator (or alternate) will determine whether the spill incident warrants
evacuation of the facility. If so, the procedures outlined in the facility Emergency Action Plan
will be followed.
8. The Spill Coordinator (or alternate) will determine whether the spill incident constitutes a
discharge as defined in §112.1(b) of the SPCC regulations (see Section 3, below) and will
notify appropriate federal, state, and local agencies of the spill/release incident if warranted.
9. If the spill involves a minor volume of oil, it can be cleaned up by facility personnel provided
that 1) they are OSHA trained and have received their current refresher training; 2) appropriate
material safety data sheets (MSDS sheets) are available for the material spilled; and 3)
appropriate personal protective equipment (PPE) is available.
10. If the spill involves a significant volume of oil, or any of the three criteria listed in (9) above are
not met, it should be cleaned up by a properly certified outside contractor (see attached Oil
Spill Incident Notification Phone Numbers).
3. Oil Spill Emergency Reporting
If the release constitutes a discharge as defined in §112.1(b) of the SPCC regulations, it will be
considered an Oil Spill Emergency. A release of oil is c onsidered a discharge under this Plan
only if: th e release i s into or upon the navigable waters of the United States, a djoining
shorelines, or waters contiguous with navigable waters of the United States. This is apparent if
a release impacts surface water quality by causing a film, sheen, or discoloration of the water surface,
or upon water or adjoining shorelines, or causes a sludge or emulsion to be deposited beneath the
surface of the adjoining shorelines. Impacts to groundwater also apply if the groundwater is
contiguous with navigable waters of the United States (i.e., groundwater discharges to/contributes to
the total volume of a surface water body that is itself contiguous with navigable waters of the United
States).
In summary, if a release directly affects surface water or groundwater at the facility, it must be
considered an Oil Spill Emergency. Federal and local authorities to be notified in the event of an Oil
Spill Emergency are outlined below.
State of Colorado
In Colorado, condensate and E&P wastes are to be reported within 24 hours if the spill has entered
waters of the state (any surface or groundwater) or entered navigable waters (any surface water) in
sufficient quantities to cause a sheen on the water or stain on the shore. Spills less than 5 barrels
which can be immediately contained and cleaned up do not need to be reported. Spills greater than
20 barrels must be reported with 24 hours.
All spills and releases of exploration and production waste or produced fluid exceeding five barrels,
including those contained within unlined berms, shall be reported in writing on the Colorado Oil and
Gas Conservation Commission (COGCC) Spill/Release Report Form 19 within 10 days of discovery
of the spill. In addition, spills or releases that exceed twenty barrels of exploration and production
waste or produced fluid shall be verbally reported to the COGCC within 24 hours of discovery. Spills
or releases of any size that impact or threaten to impact any waters of the state, residence or
occupied structure, livestock or public byway, shall be verbally reported to the COGCC as soon as
practicable after discovery. See COGCC Rule 906 for more information. If the spill may reach waters
of the State (which include surface water, ground water and dry gullies or storm sewers leading to
surface water), it must also be reported immediately to the Colorado Department of Public Health and
Environment.
Refined petroleum releases must be reported if they have entered navigable waters or if the quantity
release exceeds 25 gallons.
In general, verbal or telephone reports are to be made within 24 hours. The District Manager or
Environmental Coordinator will notify regulatory agencies as appropriate. As a practical matter, an
evaluation of the specifics of each spill and a determination of reporting requirements will be made. If
there is any question about reporting requirements, Noble will over-report rather than under-report.
Written, follow up reports are to be sent within 10 days to:
- Colorado Oil and Gas Conservation Commission
1120 Lincoln # 801
Denver, Colorado 80203
(Use COGCC Spill/Release Form)
- Bureau of Land Management - File an "Undesirable Event Form" with:
Glenwood Springs Resource Area Office
50629 Highways 6 and 24
P.O. Box 1009
Glenwood Springs, CO 81602
If the Local Emergency Planning Commission (LEPC) was notified of the spill (in the event of a
hazardous substance release) a report should also be sent to:
Chris Bornholdt Larry Chenoweth
Garfield County LEPC Mesa County LEPC
107 8th Street P.O. Box 2242
Glenwood Springs, Colorado 81601 Grand Junction, CO 81502
United States Environmental Protection Agency (EPA)
An oil spill is reportable to the EPA if any of the following criteria are met:
A) Is the spill to navigable waters or adjoining shorelines?
B) Could Water Quality Standards be violated?
C) Could the spill cause a film, “sheen”, or discoloration?
D) Could the spill cause a sludge or emulsion?
E) Do any of the reporting exemptions apply?
Exemptions include 1) Properly functioning vessel engines not deemed harmful, 2) Research
and Development Releases (approved on a case by case basis), 3) NPDES Permitted
Releases, and 4) Discharges Permitted Under the International Convention for the Prevention
of Pollution from Ships (MARPOL)
If the answer to any question A through D above is “yes” and none of the exemptions apply then the
release is reportable to the EPA.
To report an oil spill or hazardous substance release, call
• the National Response Center: (800) 424-8802
For information on EPA’s Oil Spill Program, call the Oil Spill Program Information Line at (800) 424-
9346.

4. Follow-up Activities
After the initial response, reporting, and notification associated with a spill incident, the Spill
Coordinator (or alternate) will prepare a written report which includes following:
1. Time and date of the incident;
2. Source and exact location of the spill;
3. Material involved;
4. Cause of the incident;
5. Estimated spill volume;
6. Names of any waterways involved;
7. Description of all media impacted by the spill;
8. Description of damages or injuries caused by the spill;
9. Actions taken to stop, remove, and mitigate the effects of the material spilled
10. Names of individuals and organizations contacted (time, day, who received call, who called
from Noble, and pertinent notes).
11. Who reported to the scene from Federal, State, and Local agencies (time, day, etc)?
In addition, whenever more than 1,000-gallons of oil are discharged in a single incident or more than
42-gallons of oil have been discharged in each of two incidents over a 12-month period, Noble will
submit a report to the United States Environmental Protection Agency (USEPA) Regional
Administrator (RA) as outlined in Section 5.2 of the SPCC Plan.
5. Sustained Actions
Where prolonged mitigation and recovery actions are required in response to a spill or release, the
Spill Coordinator (or alternate) will manage the activities with any or all of the following, as warranted:
1. An outside contractor.
2. An environmental/engineering consultant.
3. Any outside vendor responsible for the incident.
4. The appropriate local, state, and federal agencies.
Most release incidents at the Piceance Area Production Unit are expected to be handled without
implementing sustained actions.

Inspection Procedures and Records
1. Responsibilities
These procedures establish the requirements for periodic inspections and tests for the oil storage
vessels and oil-filled equipment listed at the Piceance Area Production Unit, to minimize the risk of a
spill incident. The Environmental Coordinator is responsible for the implementation of these
procedures. Specifically, the Environmental Coordinator is responsible for:
Conducting the inspections;
Producing documentation for deficiencies found during the inspections; and
Making certain that remediation or repair work is properly prioritized and completed in a timely
manner.
The Environmental Coordinator may designate another personnel member to complete the
inspections. Designated personnel will have the authority to commit the resources necessary to carry
out a response, if warranted. Operating personnel at the Piceance Area Production Unit receive
training to familiarize themselves with all aspects of the SPCC Plan, facility operations, the location
and characteristics of materials handled at the facility, and the location of pertinent records within the
facility.
2. Procedures
The Environmental Coordinator (or designee) will conduct an annual visual inspection of the oil
storage vessels and oil-filled equipment identified in Section 6.5 of the SPCC Plan. The inspections
will be documented using the attached inspection forms. The annual inspection includes a visual
examination of exterior surfaces for leaks and other deficiencies of the vessel, supports, connected
piping and valves and secondary containment. It also includes visual inspection and monitoring of
any leak detection system or other monitoring or warning systems (e.g., level indication/alarm or
interstitial space monitoring). If any inspection reveals a leak or equipment deficiency outside of
normal operating conditions, corrective action must be taken promptly to eliminate the leak or
deficiency. Deficiencies noted during the inspection are recorded as a work order. The inspector will
complete the following:
1. Visually inspect exterior surfaces of storage vessels and oil-filled equipment, along with
associated pipes, valves and other appurtenances and identify any leaks, cracks, area of
wear, external wall thinning, swelling, excessive corrosion or mechanical deficiency.
2. Visually inspect vessel/equipment supports and containment structures for excessive
settlement, apparent structural weakness, cracks or other deficiency that would allow the
secondary containment to leak.
3. Inspect and monitor existing leak detection systems (for example, observation ports on
double-bottom tanks), cathodic protection equipment and other warning systems such as
alarms and level gauges.
If, during the annual inspection, the inspector observes a spill of oil from any of the equipment the
inspector shall immediately initiate the oil spill response procedures outlined in Appendix C of this
SPCC Plan.

Noble Energy, Inc. -Traffic Study
Rulison Compressor Site
Page 2of4
A. EXISTING ROADS
Noble Energy, Inc.'s Rulison Compressor site is an already constructed site
approximately 13.7 miles east of Parachute, Colorado. In order to access the location,
one would take the I-70 frontage road east to CR 323 (Rulison Road), and then
proceed approximately 0.4 miles south to CR 320 (Rifle-Rulison Road), then
southeast approximately 3.79 miles to CR 329 (Spruce Creek Road), and finally
travelling southwest approximately 2.4 miles to the compressor station.
The attached map (Attachment A) depicts the site location, existing and proposed
roads (none) and access points, all County roads within a one (I) mile radius of the
site, and the nearest proximate intersections with state or federal highways; however
these are unlikely to receive traffic impacts from the site given the sparseness of any
such traffic . There will be no activity areas for construction of this existing site.
B. EXISTING LAND USES AT SITE
The property at the site is zoned Rural with light industrial application at the site
with the compressor facilities and associated equipment in place. All road systems in
this plan can be reviewed on the attached Map, herewith, as Attachment A.
Cu1Tent nip generation estimates (based on interviews with Noble Energy staff)
show two trip ends per day accessing/leaving the Rulison site. On a weekly basis,
there may be an average of 5 light vehicles accessing the site to monitor/maintain the
facility. The Average Daily Traffic Count Map is included herewith as Attachment
A.
The County dliveway pennit is currently being handled by Noble Energy, Inc.
This site includes no pe1mit requirements for access to a state highway or railroad
crossings.
Any required surface use, access or easement agreements required to access the
site have been separately agreed to with the surface owner.
No other traffic info1mation and/or legal constraints subjecting the subject site are
anticipated.
C. PROPOSED LAND USES AND TRIP GENERATION
PROJECTIONS
The Rulison Compressor site has been constructed, as understood between Noble
Energy, Inc., and the County's Planning and Zoning Office. Consequently no trip
projections are included herein for the construction phase of the project. CmTently,
the land use of the Rulison Compressor site is Rural.
Noble Energy, Inc. -Traffic Study
Rulison Compressor Site
Page 3of4
The site acreage, 5.74 acres, does not fall in data range of the Institute of
Transportation Engineer's (ITE's) Trip Generation Manual data plots (Code 110). As
a result, the ITE Trip Generation Handbook recommends collecting local data. Local
Data was conducted via interviews of Noble field personnel, which indicated that 1
light vehicle enters the site daily (2 trip ends/day). Table 1 below summarizes the
Garfield County 2002 ADT and Rulison Compressor Station ADT for each impacted
county road segment.

RE: Letter Report of Findings-Class I Cultural Resources Study for the proposed expansion of the Noble Energy
Rulison Compressor Station (Parcel #2405-084-00-024), Garfield County, Colorado
Dear Mr. Griffin,
This letter report of findings serves as documentation for the completion of a Class I Cultural Resources
Study of the proposed expansion of the Noble Energy Rulison Compressor Station in the NE SE of Section 8, T7S,
R94W, in Garfield County, Co lorado. The footprint of the existing facility is contained within Parcel Number
Z4U~-084 -0U-024. This report satisfies the requirements of the Garfield County Unified Land Use Resolution,
Article IV Section 4-502E part 8b: A determination of the effect on significant archaeological, cultural,
paleontological, historic resources. Cultural resource files for Sections 8, 9, and 17, T7S, R94W were reviewed tor
this study.
The existing compressor station is situated between Cache and Spruce Creeks, and is south of the
Colorado River. It is approximately 3.5 miles southeast of Rulison, Colorado . Access to the project area will
utilize existing roads.
The file search was conducted on January 17, 2011, by reviewing the Colorado Office of Archaeology and
Historic Preservation's COMPASS database. A total of 17 previous cultural resource inventory projects have
taken place in Sections 8, 9, and 17, T7S, R94W (Table 1); a total of 26 cultural resources have been recorded as
a result of these projects (Table 2). Si x of the cultural resources are officially eligible for inclusion on the
National Register of Historic Places (NRHP), including a historic habitation and prehistoric open camp site
{SGF875), a prehistoric open camp site (SGF4060), and the recorded segments of the Martin and Kennedy Ditch
Kae McDonald
Principal Investigator
f/attopsarchaeological99 @comcasf.net
(SGF4161.1 and SGF4162 .2) and the Blue Bird Ditch (SGF4162.1 and SGF4162.3). Based on the legal
descriptions of these sites, they are located outside of the currently proposed project area, and should not be
impacted. The remaining sites are either officially not eligible for inclusion on the NRHP, or field evaluated not
eligible. Thus, based on the results of this Class I inventory, Flattops Archaeological Consultants recommends a
finding of no historic properties affected. However, should cultural resources be unearthed during ground-
disturbing activities, a qualified archaeologist should be notified.
If you have questions or concerns, please do not hesitate to contact me at your convenience.

Preface
Soil surveys contain information that affects land use planning in survey areas. They
highlight soil limitations that affect various land uses and provide information about
the properties of the soils in the survey areas. Soil surveys are designed for many
different users, including farmers, ranchers, foresters, agronomists, urban planners,
community officials, engineers, developers, builders, and home buyers. Also,
conservationists, teachers, students, and specialists in recreation, waste disposal,
and pollution control can use the surveys to help them understand, protect, or enhance
the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil properties
that are used in making various land use or land treatment decisions. The information
is intended to help the land users identify and reduce the effects of soil limitations on
various land uses. The landowner or user is responsible for identifying and complying
with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some cases.
Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain
conservation and engineering applications. For more detailed information, contact
your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app?
agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/

Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic
tank absorption fields. A high water table makes a soil poorly suited to basements or
underground installations.
The National Cooperative Soil Survey is a joint effort of the United States Department
of Agriculture and other Federal agencies, State agencies including the Agricultural
Experiment Stations, and local agencies. The Natural Resources Conservation
Service (NRCS) has leadership for the Federal part of the National Cooperative Soil
Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil
Data Mart is the data storage site for the official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous areas
in a specific area. They include a description of the soils and miscellaneous areas and
their location on the landscape and tables that show soil properties and limitations
affecting various uses. Soil scientists observed the steepness, length, and shape of
the slopes; the general pattern of drainage; the kinds of crops and native plants; and
the kinds of bedrock. They observed and described many soil profiles. A soil profile is
the sequence of natural layers, or horizons, in a soil. The profile extends from the
surface down into the unconsolidated material in which the soil formed or from the
surface down to bedrock. The unconsolidated material is devoid of roots and other
living organisms and has not been changed by other biological activity.
Currently, soils are mapped according to the boundaries of major land resource areas
(MLRAs). MLRAs are geographically associated land resource units that share
common characteristics related to physiography, geology, climate, water resources,
soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically
consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that is
related to the geology, landforms, relief, climate, and natural vegetation of the area.
Each kind of soil and miscellaneous area is associated with a particular kind of
landform or with a segment of the landform. By observing the soils and miscellaneous
areas in the survey area and relating their position to specific segments of the
landform, a soil scientist develops a concept, or model, of how they were formed. Thus,
during mapping, this model enables the soil scientist to predict with a considerable
degree of accuracy the kind of soil or miscellaneous area at a specific location on the
landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented by
an understanding of the soil-vegetation-landscape relationship, are sufficient to verify
predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them to
identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character of
soil properties and the arrangement of horizons within the profile. After the soil
scientists classified and named the soils in the survey area, they compared the
5
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that have
similar use and management requirements. Each map unit is defined by a unique
combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components of
the map unit. The presence of minor components in a map unit in no way diminishes
the usefulness or accuracy of the data. The delineation of such landforms and
landform segments on the map provides sufficient information for the development of
resource plans. If intensive use of small areas is planned, onsite investigation is
needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape, and
experience of the soil scientist. Observations are made to test and refine the soil-
landscape model and predictions and to verify the classification of the soils at specific
locations. Once the soil-landscape model is refined, a significantly smaller number of
measurements of individual soil properties are made and recorded. These
measurements may include field measurements, such as those for color, depth to
bedrock, and texture, and laboratory measurements, such as those for content of
sand, silt, clay, salt, and other components. Properties of each soil typically vary from
one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists interpret
the data from these analyses and tests as well as the field-observed characteristics
and the soil properties to determine the expected behavior of the soils under different
uses. Interpretations for all of the soils are field tested through observation of the soils
in different uses and under different levels of management. Some interpretations are
modified to fit local conditions, and some new interpretations are developed to meet
local needs. Data are assembled from other sources, such as research information,
production records, and field experience of specialists. For example, data on crop
yields under defined levels of management are assembled from farm records and from
field or plot experiments on the same kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on such
variables as climate and biological activity. Soil conditions are predictable over long
periods of time, but they are not predictable from year to year. For example, soil
scientists can predict with a fairly high degree of accuracy that a given soil will have
a high water table within certain depths in most years, but they cannot predict that a
high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and
identified each as a specific map unit. Aerial photographs show trees, buildings, fields,
roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the landscape,
however, the soils are natural phenomena, and they have the characteristic variability
of all natural phenomena. Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if ever, can be mapped without including areas of other taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used.
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments
on the map provides sufficient information for the development of resource plans. If
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Each
description includes general facts about the unit and gives important soil properties
and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other characteristics that affect their use. On the basis of such
differences, a soil series is divided into soil phases. Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the soils or miscellaneous areas are somewhat similar in all
areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present or
anticipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform. An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material
and support little or no vegetation. Rock outcrop is an example.

Soil Information for All Uses
Suitabilities and Limitations for Use
The Suitabilities and Limitations for Use section includes various soil interpretations
displayed as thematic maps with a summary table for the soil map units in the selected
area of interest. A single value or rating for each map unit is generated by aggregating
the interpretive ratings of individual map unit components. This aggregation process
is defined for each interpretation.
Building Site Development
Building site development interpretations are designed to be used as tools for
evaluating soil suitability and identifying soil limitations for various construction
purposes. As part of the interpretation process, the rating applies to each soil in its
described condition and does not consider present land use. Example interpretations
can include corrosion of concrete and steel, shallow excavations, dwellings with and
without basements, small commercial buildings, local roads and streets, and lawns
and landscaping.
Corrosion of Steel
"Risk of corrosion" pertains to potential soil-induced electrochemical or chemical
action that corrodes or weakens uncoated steel. The rate of corrosion of uncoated
steel is related to such factors as soil moisture, particle-size distribution, acidity, and
electrical conductivity of the soil. Special site examination and design may be needed
if the combination of factors results in a severe hazard of corrosion. The steel in
installations that intersect soil boundaries or soil layers is more susceptible to
corrosion than the steel in installations that are entirely within one kind of soil or within
one soil layer.
The risk of corrosion is expressed as "low," "moderate," or "high."

Aggregation Method: Dominant Condition
Aggregation is the process by which a set of component attribute values is reduced
to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is either
some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being
aggregated, the first step of the aggregation process is to derive one attribute value
for each of a map unit's components. From this set of component attributes, the next
step of the aggregation process derives a single value that represents the map unit
as a whole. Once a single value for each map unit is derived, a thematic map for soil
map units can be rendered. Aggregation must be done because, on any soil map, map
units are delineated but components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding component
typically makes up approximately 60% of the map unit. Percent composition is a critical
factor in some, but not all, aggregation methods.
The aggregation method "Dominant Condition" first groups like attribute values for the
components in a map unit. For each group, percent composition is set to the sum of
the percent composition of all components participating in that group. These groups
now represent "conditions" rather than components. The attribute value associated
with the group with the highest cumulative percent composition is returned. If more
than one group shares the highest cumulative percent composition, the corresponding
"tie-break" rule determines which value should be returned. The "tie-break" rule
indicates whether the lower or higher group value should be returned in the case of a
percent composition tie.
The result returned by this aggregation method represents the dominant condition
throughout the map unit only when no tie has occurred.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Custom Soil Resource Report
18
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Corrosion of Concrete
"Risk of corrosion" pertains to potential soil-induced electrochemical or chemical
action that corrodes or weakens concrete. The rate of corrosion of concrete is based
mainly on the sulfate and sodium content, texture, moisture content, and acidity of the
soil. Special site examination and design may be needed if the combination of factors
results in a severe hazard of corrosion. The concrete in installations that intersect soil
boundaries or soil layers is more susceptible to corrosion than the concrete in
installations that are entirely within one kind of soil or within one soil layer.
The risk of corrosion is expressed as "low," "moderate," or "high."

Aggregation Method: Dominant Condition
Aggregation is the process by which a set of component attribute values is reduced
to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is either
some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being
aggregated, the first step of the aggregation process is to derive one attribute value
for each of a map unit's components. From this set of component attributes, the next
step of the aggregation process derives a single value that represents the map unit
as a whole. Once a single value for each map unit is derived, a thematic map for soil
map units can be rendered. Aggregation must be done because, on any soil map, map
units are delineated but components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding component
typically makes up approximately 60% of the map unit. Percent composition is a critical
factor in some, but not all, aggregation methods.
The aggregation method "Dominant Condition" first groups like attribute values for the
components in a map unit. For each group, percent composition is set to the sum of
the percent composition of all components participating in that group. These groups
now represent "conditions" rather than components. The attribute value associated
with the group with the highest cumulative percent composition is returned. If more
than one group shares the highest cumulative percent composition, the corresponding
"tie-break" rule determines which value should be returned. The "tie-break" rule
indicates whether the lower or higher group value should be returned in the case of a
percent composition tie.
The result returned by this aggregation method represents the dominant condition
throughout the map unit only when no tie has occurred.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Custom Soil Resource Report

Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.

Ecological Site Assessment
Individual soil map unit components can be correlated to a particular ecological site.
The Ecological Site Assessment section includes ecological site descriptions, plant
growth curves, state and transition models, and selected National Plants database
information.
All Ecological Sites — Rangeland
An "ecological site" is the product of all the environmental factors responsible for its
development. It has characteristic soils that have developed over time; a characteristic
hydrology, particularly infiltration and runoff, that has developed over time; and a
characteristic plant community (kind and amount of vegetation). The vegetation, soils,
and hydrology are all interrelated. Each is influenced by the others and influences the
development of the others. For example, the hydrology of the site is influenced by
development of the soil and plant community. The plant community on an ecological
site is typified by an association of species that differs from that of other ecological
sites in the kind and/or proportion of species or in total production.
An ecological site name provides a general description of a particular ecological site.
For example, "Loamy Upland" is the name of a rangeland ecological site. An
"ecological site ID" is the symbol assigned to a particular ecological site.
The map identifies the dominant ecological site for each map unit, aggregated by
dominant condition. Other ecological sites may occur within each map unit. Each map
unit typically consists of one or more components (soils and/or miscellaneous areas).
Each soil component is associated with an ecological site. Miscellaneous areas, such
as rock outcrop, sand dunes, and badlands, have little or no soil material and support
little or no vegetation and therefore are not linked to an ecological site. The table below
the map lists all of the ecological sites for each map unit component in your area of
interest.

Piceance Noxious Weed Management Plan January 2010 1-1
1.0 INTRODUCTION
Noxious weeds are often non-native plant species which have been introduced into an environment with
few, if any, natural biological controls, thus providing them a distinct competitive advantage in
dominating and displacing native plant species. They possess the ability to dominate plant communities
to the extent plant diversity and ecosystem integrity are threatened. Noxious weeds also threaten valuable
wildlife habitat, cause economic hardships to agriculture and are a nuisance for recreational activities.
Noxious weeds are difficult to eradicate or control because they readily become established in disturbed
areas, spread rapidly, possess a unique ability to reproduce profusely, and resist control.
In general, noxious weeds are most common in areas where human activity is having or has had the
greatest impact on the soil and vegetation and/or where human activities have resulted in the introduction
of seed sources. Previously disturbed land, where the plant cover has been removed is susceptible to
noxious weed establishment and invasion into adjacent native plant communities. These include
roadways, rock or borrow pits, heavily grazed areas, mining, gas and oil drilling areas, and irrigation
canals.
Species of noxious weeds that are known to occur in the Mesa/Garfield County area in Colorado are
listed in Table 1. There are state and federal laws that provide definitions of and guidance for the
management of noxious weeds (Colorado Department of Agriculture 2009a,b).
The Noxious Weed Management Plan (Plan) provides a process for implementing noxious weed
management strategies to be used by Noble Energy Inc. (NEI) during activities in the Piceance Field. The
guiding purpose of noxious weed management in this Plan is to preclude the inadvertent introduction,
establishment, or proliferation of noxious weed species as a result of NEI development activities. It is the
intent of NEI to cooperate with federal and state agencies, local landowners, county weed control agents,
and other parties in the management and control of noxious weeds in the area.

2.0 PLAN OVERVIEW
The primary goal of this Plan is to preclude the inadvertent introduction, establishment or proliferation of
any noxious weed species as a result of the proposed activities. The shared goals of: 1) prevention, 2)
treatment, 3) monitoring, and 4) cooperation form the framework of this Plan. Each goal is characterized
by specific management objectives intended to achieve the goal. Each objective has specific actions that
will be implemented by NEI.
The following summarizes the goals of this Plan.
1) Prevention
Preventive actions include conducting periodic weed surveys and the use of weed-free seed mixtures
during reclamation. Weed surveys of the field will be conducted by a local weed expert to identify
noxious species on a scheduled basis so that infestations can be treated quickly before they spread.
Revegetation activities will be completed in all disturbed areas not required to be vegetation-free. Proper
and timely revegetation with desirable species will create less favorable conditions for weed growth and
spread. Revegetation will be done with weed-free seed and mulch. Disturbances will minimize spread of
weeds by treating them prior to disturbance or avoiding them.
2) Treatment
Treatments will be developed using integrated weed management principles for each species and
situation. Treatments may include hand pulling, grubbing, mowing, mulching, seeding, burning,
herbicide application and soil management, as recommended by NEI’s local weed expert. All treatments
will follow the guidelines stipulated in this Plan. Large and/or widespread weed infestations that are
beyond the control and influence of NEI will be managed cooperatively with other parties. All treatments
will be monitored for effectiveness.
3) Monitoring
Monitoring will be conducted on a scheduled basis to detect new infestations, evaluate prevention and/or
treatment success, and identify the need for re-treatment.
4) Cooperation
NEI will cooperate with the U.S. Bureau of Land Management, Garfield and Mesa Counties and affected
landowners to manage noxious weeds in the project area.
Piceance Noxious Weed Management Plan January 2010 3-1
3.0 GOALS AND OBJECTIVES
Goal 1. Prevention
Objective 1: Forestall or hinder the introduction and spread of specific noxious weed species in areas
not currently infested.
Action:
Ensure that disturbed land adjacent to vegetation-free zones is revegetated immediately after
disturbance.
Although revegetation after ground disturbance is a guiding principle for the management of weeds,
NEI requires vegetation-free zones around their well pads and infrastructure for safety reasons. This
vegetation-free zone is approximately 250 feet by 300 feet or an estimated 1.6 acres for each well
pad.
Outside of the vegetation-free zones, NEI will revegetate bare ground regardless of whether noxious
weeds are in the local area. Native plant species (or domestic varieties of native species) will be
used instead of introduced species for seeding for site protection if the native species can accomplish
the site objectives in a reasonable time frame and costs are not excessive. Species and seed mixes
that will become established will be used for the reclamation of disturbed ground. Generally, the
addition of broadleaf species to seed mixes will be avoided as reseeded areas often require
herbicidal treatment of broadleaf weeds in the first year or two, which would also affect all desirable
broadleaf species in the treated area. All seed purchased for reclamation purposes will be free of
noxious weeds. If hay or straw will be used for mulching, erosion control, rehabilitation, or other
uses, it will be free of noxious weeds and their seeds. On national BLM Lands, reclamation will use
the approved BLM seed mixes listed in Tables 2-1 through 2-4.

Piceance Noxious Weed Management Plan January 2010 3-3
Piceance Noxious Weed Management Plan January 2010 3-4
Objective 2: Prevent the spread or proliferation of existing infestations.
Action:
Conduct ground disturbing actions consistent with the goals and objectives of this Plan.
Where road shoulders or drainage ditches are covered by desirable herbaceous cover, consider
leaving it in place rather than clearing it off, if such a practice can be done without causing excessive
damage to the road or ground surface or cause significant public safety hazards.
Use the following guidelines for existing infestations to be disturbed:
(1) if the weed is not in flower, or will not reproduce through damaged plant parts (i.e.,
vegetatively), proceed with maintenance/road work,
(2) if the weed has flowered, either hand pull or cut all tops, bag in a plastic bag (and dispose of
appropriately), then proceed with road work; or flag the site for avoidance by the machinery
until the infestation is treated; and
(3) if the weed is known or suspected to sprout vegetatively from cut parts, flag the site to ensure
avoidance by machinery until the weed can be treated by proper means.
Goal 2. Treatment
Objective 1: Evaluate treatment options for established infestations.
Actions:
Evaluate each infestation for causal factors and appropriate treatment employing integrated weed
management principles.
Integrated Weed Management (IWM) is a decision-making process used to select the most
appropriate actions from an assortment of options and apply them to each unique situation. IWM
Piceance Noxious Weed Management Plan January 2010 3-5
evaluates, integrates, and implements noxious weed management strategies based on predicted
ecological, sociological, and economic consequences. IWM includes the use of naturally occurring
weed controls including biological diversity, competition, and plant succession. In addition, IWM
utilizes various mechanical, biological, cultural and chemical controls, and habitat modification
techniques.
Objectives will be set for each infestation and will include reasonable and attainable time frames for
management. Management objectives may include: control (to prevent reproduction), containment
(to prevent off site movement), reduction (to shrink the population in number, density, and/or area
covered); and/or eradication (to eliminate permanently from the site).
In cases where infestations extend beyond the areas affected by NEI’s activities and/or are
contributed to by management of surrounding lands, NEI will coordinate with adjacent landowners
to determine the appropriateness and anticipated effectiveness of treatment options. If adjacent lands
are not treated, NEI may decline to treat infestations on their areas or to limit their treatments to non-
chemical methods or to roadsides only. This will minimize the use of herbicides where results may
be poor.
The greatest priority for treatment will be placed on species in Garfield and Mesa County classified
as Class I. Class II species located outside of public roadways will be given less emphasis for
treatment and will not be managed if treatments are predicted to have little effect.
Prepare and Implement Treatment Plans
Treatment options appropriate for use by NEI are limited to physical, mechanical, cultural, and
chemical methods. Specific methods include hand pulling, grubbing, mowing, mulching, burning,
herbicide application, and soil management. Appropriate herbicides are a function of the target
noxious weed species and are not listed in this Plan. Specific herbicides will be determined in
conjunction with the BLM, as appropriate, in order to ensure the best, most current information is
applied. Guidelines to be followed for all treatment activities are listed in Appendix C.
All treatments will be conducted in a manner consistent with the guidelines and measures in this
Plan including all appendices. On BLM land, all treatments will be developed in coordination with
the BLM.
Piceance Noxious Weed Management Plan January 2010 3-6
Goal 3. Monitoring
Objective 1: Implement a sound monitoring program to track prevention and treatment activities and to
determine the effectiveness of such practices to meet stated objectives.
Actions:
Conduct field surveys to detect new infestations and/or changes in existing infestations.
Field surveys will be conducted periodically throughout the NEI Piceance field to monitor changes
and determine the need for new treatments and re-treatments.
Goal 4. Cooperation
Objective 1: To coordinate and integrate inventory, prevention and management of noxious weeds with
private parties; federal, state and local governments; and other agencies.
Actions:
Manage established infestations in full coordination with BLM and landowners.
Objectives for each established infestation are determined in an integrated manner and are applied
through a process based on an assessment of risks, costs/benefits, appropriate strategies and tactics.
Determine treatment options cooperatively with affected parties. (See Goals 2 and 4.)

Introduction
This report fulfills the requirements set forth in Section 4-502 of the Garfield County Unified Land Use
Resolution of September 2008. Section 4-502 requires that the Impact Analysis provide a description of
the impacts that the proposed land use change may cause, based upon the standards that the proposed
use must satisfy. This report specifically determines the cumulative effect of additional compressors on
wildlife habitat, the creation of hazardous attractions, the alteration of existing native vegetation,
blocking of migration routes, and changes in habitat use or a disruption of habitat use by wildlife.
Location and Landform
The Rulison Facility Site A Compressor Station (Compressor Station) is located approximately 5 miles
south of the Interstate 70 Rulison exit and approximately 12.8 kilometers (km - 8 miles) east of Parachute,
Colorado. The Compressor Station is located in the NE ¼ SE ¼ Section 8, Township 7 South, Range 94
West, 6th Principal Meridian (Figure 1).
Climate
Weather patterns in the project area are a result of climatic conditions interacting with the local
topography. Mild summers and cold winters are characteristic and temperatures and precipitation vary
with elevation. Mean summer temperatures range from approximately 18°C to 21°C (65 to 70°F) and
mean winter temperatures range from -4°C to -1°C (25°F to 30°F). Annual precipitation averages 32
centimeters (12.75 inches) with October being the wettest and June being the driest months respectively,
receiving 3.3 centimeters and 2.2 centimeters (1.31 and 0.87 inches) of precipitation, typically in the form
of rain during both months. Winds are typically out of the southeast, averaging approximately 12.9
kilometers per hour) (8 miles per hour). There are no significant seasonal shifts in mean wind directions
or velocities.
Wildlife Habitat
The predominant vegetation of the project area is typical of the eco-region identified as the southern
Rocky Mountain Steppe—open woodland, coniferous forest, and alpine meadow province of the dry
domain (Bailey 1995). Soils within the project area are predominantly aridisols common to foothill and
lower mountain elevations. Habitat types are determined by dominant vegetation types.
Vegetation around the Compressor Station is comprised of Gambel oak (Quercus gambelii)shrublands;
there is no vegetation located on the compressor station (Photo 1). Gambel oak shrublands often include
serviceberry (Amelanchier alnifolia)and snowberry (Symphoricarpos albus)shrubs; however,
chokecherry (Prunus virginiana ssp.melanocarpa)and mountain mahogany (Cercocarpus montanus)are
also commonly found. In the understory, elk sedge (Carex geyeri)is the most common herbaceous plant.
Other grasses and forbs include sticky false starwort (Pseudostellaria jamesiana), Nuttall’s larkspur
(Delphinium nuttallianum), lambstongue groundsel (Senecio integerrimus), and northern bedstraw
(Galium septentrionale).
Gambel oak shrublands generally do not provide habitat for federally listed species. Table 1 provides the
federally threatened, endangered, and candidate species (USFWS 2011) which may occur in Garfield
County.

The Compressor Station as it currently exists and prior to its construction and operation, does/would not
impact any federally listed species or designated critical habitat.
American elk (elk -Cervus elaphus nelsoni)and mule deer (deer -Odocoileus hemionus)are the
dominant wildlife species in Oak shrubland habitats near the Compressor Station. The Compressor
Station is mapped by the Colorado Division of Parks and Wildlife (CDOPW) as elk winter range and
concentration area, and as deer winter range. The Compressor Station sets on the southern edge of these
critical habitat types. The majority of the critical habitat is north of the Compressor Station where
agricultural lands (i.e. hay fields) are common. These agricultural lands provide winter and early spring
forage of greater quality than oak shrublands and the winter snow depth is much less.
The location of the Compressor Station does not exist within any CDOPW mapped migration corridors or
wildlife habitat linkages. The initial construction and operation of the Compressor Station likely did
cause a decrease in habitat use by deer and elk within at a minimum of 400 meters. Research shows that
deer and elk will avoid human use areas, but with time use of these areas can return to near pre-
disturbance levels if habitat conditions are capable of providing hiding cover (e.g. in areas clear of
vegetation wildlife will have a reaction to humans, noise, etc. at a greater distance than if the same
disturbance was occurring in heavy shrublands).
Additional development at the compressor station will not create hazardous attractions to avian or
mammalian wildlife species, alter additional native vegetation, block migration routes, or cause a change
in habitat use. The cumulative effect of the addition of more compressors will not result in an impact to
wildlife for the following reasons:
The Rulison Facility Site A Compressor Station is existing and is devoid of wildlife habitat.
Noble Energy, Inc. Cache Creek Master Development Plan Biological Evaluation

Wildlife has become accustomed to the presence of the compressor station, human activity
associated with the compressor station, and the noise of the compressor station.
Additionally, it is preferred to ‘cluster’ impacts and human activity within one area to reduce the total
direct impacts (loss of habitat) and indirect impacts (human activity and avoidance of areas) to wildlife.
The addition of compressors at this location will help to cluster impacts and eliminate the need for
additional compressor locations in habitat that is not impacted and developed.

2.0 INTRODUCTION
On June 30, 2005, the State of Colorado stormwater regulation went into effect to require
Colorado Discharge Permit System (CDPS) permits from the Colorado Department of Public
Health and Environment (CDPHE) Water Quality Control Division (WQCD) for stormwater
discharges from construction activities associated with small construction activity for oil and gas
sites that disturb between one and five acres. As part of that requirement, this Stormwater
Management Plan (SWMP) has been prepared to identify possible pollutant sources to
stormwater and to set out Best Management Practices (BMPs) to reduce or eliminate possible
water quality impacts.
The five-year stormwater general permit COR-030000 was re-issued and became effective on
July 1, 2007. Noble applied for coverage under the stormwater general permit and was re-issued
COR-039527 for the Piceance Drilling Program Area. Copies of the permit documents are
included in this SWMP as Appendix A.
Noble utilizes a database called SWIM (Oil Field Facility Environmental Compliance) to record
many of the reporting requirements of the stormwater permit. SWIM is web-based and consists
of an online database of up-to-date site-specific information, including records of all inspection
reports, site maintenance and repairs, site maps and site specific narratives. While SWIM allows
Noble to better manage its stormwater program, it does require some training to navigate
properly. Access and navigation instructions for SWIM are provided in Appendix C of this
document. It is suggested that anyone wishing to utilize the web-based database first review the
contents of Appendix C.
This stormwater management plan document is general in nature as it applies to a large field
made up of many unique sites in various stages of construction and remediation. More specific
and detailed information for each individual site can be found in the site maps and site specific
narratives found in the SWIM database, described above.
3.0 SWMP ADMINISTRATOR
The SWMP Administrator for Noble is responsible for the developing, implementing, maintaining,
and revising the SWMP. The SWMP Administrator has the authority to dedicate the financial and

4.0 SITE DESCRIPTION
The following section describes aspects of the entire Piceance Drilling Program Area. More
detailed descriptions of individual sites within the Piceance Drilling Program Area can be found
in the Site Specific Narrative documents, located in the SWIM database (see Appendix C for
SWIM access and navigation instructions).
4.1 Nature of Construction Activity
Noble is one of the nation’s leading independent energy companies engaged in the exploration,
development, production, and marketing of crude oil and natural gas. Noble currently owns or
leases oil and natural gas mineral rights in the Piceance Basin, Garfield and Mesa Counties,
Colorado. Noble’s Piceance Basin Drilling Program Area lies within Sections 1, 2, 7, 8, 11, 12,
14, 15, & 18 of Township 8 South, Range 96 West; Sections 5, 7, 17, 18, 19, 20, 21, 23, 24, 26, 27,
31, 32, 33, 34 of Township 7 South 94 West; and Sections 12, 24, 25, 26, 27, 32, 33, 34, 35, 36 of
Township 7 South 95 West of Garfield and Mesa Counties in Colorado. The town of Parachute,
Colorado is the nearest population center.
The Noble Piceance field is currently comprised of three separate areas: Rulison, South Grand
Valley and Battlement Mesa. A sitewide map of the Piceance field is provided as Figure 1, with
the different areas depicted in Figures 2-4 (Rulison), Figures 5-7 (South Grand Valley) and
Figures 8-10 (Battlement Mesa).
The current drilling and development plan includes pad construction, access road
improvement/construction, reserve pit construction, installation of associated production facilities,
well drilling, well completion, well fracing/testing and pipeline construction. The estimated total
area covered under the CDPS General Permit, COR-039527, is 20,000 acres, of which up to 200
acres may be classified as disturbed at any one time. The permitted area also includes field and
site-specific access roads and pipelines.
The Piceance Basin wells will be constructed using conventional cut and fill earthmoving
techniques. Typically, the working pad surface will have dimension of approximately 200 feet by
400 feet. Each pad may have a reserve pit that is approximately 60 feet by 250 feet. Specific pad
dimensions vary depending on the planned drill rig, number of wells to be drilled from each pad,
4
and local conditions. Reserve pits will be used during activities to contain drilling fluids and
cuttings. The reserve pits will be designed, constructed, and reclaimed according to Colorado Oil
and Gas Conservation Commission (COGCC) requirements.
Regional precipitation amounts vary from 11.59 inches per year in Rifle, Colorado to 14.8 inches
in Colbran, Colorado (Western Regional Climate Center).
Due to regional climate conditions, lack of surface water or near-surface ground water, and well
pad construction design, construction dewatering is not expected for Piceance Basin development
activities.
4.2 Sequence of Major Activities
This section outlines the progression from one construction stage to another for a site. These
stages differ depending on the type of site (well pads, pipeline right-of-ways, and access roads).
Below the sequence of major activities for these sites is outlined along with the general
stormwater controls utilized during each stage. Information regarding the specific BMPs used at
each site during each construction stage can be found on respective site maps and site specific
narrative documents, located in the SWIM database (see Appendix C for SWIM access and
navigation instructions).
4.2.1 Well Pads
4.2.1.1 Construction Stages
The process of planning, constructing and reclaiming a well pad is broken down into seven distinct
construction stages. The stages are New Site, Pre-Build, Construction, Completed, Interim
Reclamation, Final Reclamation and Returned. Each stage and the steps taken to manage
stormwater are briefly discussed below.
New Site
The New Site stage is a planning stage that includes investigation of proper pad placement and
orientation, as well as identification of sensitive areas and stormwater BMP planning. Once
locations are selected for well or facility pads, and associated access roads and pipeline right-of-
ways, engineered designs are drawn which include the stormwater BMPs to be installed for the
Construction, Completed and Interim Reclamation pad stages. Electronic versions of the new site
design drawings are added to the site map files located in the SWIM database at this stage.
Specific location information, including legals, is also entered into the SWIM database at this stage
(see Appendix C for SWIM access and navigation instructions).
Site specific BMPs will be engineered to contain/control the anticipated flow of surface water at
each location and to adequately control erosion and sediment discharge. Such BMPs will address
proper slope stabilization, diversions, perimeter control, armoring and stormwater filtering, and
will be specifically designed for the unique conditions anticipated at each construction site. To the
5
extent possible, BMPs that will be utilized to control stormwater throughout the life of the wells
will be designed during this stage.
A pad will remain in the New Site stage until BMPs have been engineered and a date planned for
site construction, at which point the site will enter the Pre-Build stage.
Pre-Build
During the Pre-Build stage, protective measures are taken to protect sensitive areas that have been
identified in the New Site stage. Perimeter control BMPs are installed around the area to be
disturbed, which generally include filter or diversion BMPs installed downgradient of the
disturbance area. In regions where the local conditions warrant it, diversion BMPs may be
installed upgradient from the disturbance area prior to construction to prevent excessive
stormwater runon during construction activities.
A pad will remain in the Pre-build stage until earthwork or disturbance is initiated at the site, after
which the site will enter the Construction stage.
Construction
The Construction stage includes the construction of the well pad surface and any associated access
roads or pipelines. Further details pertaining to access road and pipeline construction and
associated stormwater management can be found in Section 4.2.2. Most work will be performed
using traditional cut-and-fill construction but may also involve blasting. Reserve pits are generally
constructed at this time to store certain fluids and solids during later stages of drilling and
completion operations. The pad surface will be built with a slight grade to drain surface water into
the reserve pit or to other capture devices. No fluids or solids, excluding any accumulated
stormwater, will be stored in the reserve pits during this stage. The initiation of the construction
stage also initiates the regular stormwater inspection schedule (see Section 8.2 for inspection
details).
The basic construction activities that are conducted during this stage include clearing and
grubbing; segregation of topsoil for use in reclamation; grading and excavation; compaction of
well pad and road surfaces; final grading and contouring; installation of gravel or other materials
on well pads and road surfaces; and construction of engineered and non-engineered stormwater
BMPs according to the pad designs.
Sediment discharge is the main potential pollutant of concern during this stage of construction. No
chemicals or fuels will be stored on the pad during this stage, however, attention will be paid to the
potential for spills that might occur during the refueling and use of construction equipment.
Structural BMPs will be installed and maintained according to the pre-build design during this
stage to reduce erosion and eliminate sediment discharges. Changes to the pre-build design may
6
need to be made to reflect changing field conditions or objectives, and may include changes to
designed stormwater BMPs. Certain non-structural BMPs may be utilized to assist in managing
stormwater compliance such as limiting traffic; conducting training and inspections; minimizing
the disturbed area to only the required dimensions; preservation of mature vegetation, such as
protective trees; standard procedures for refueling and maintaining equipment to prevent spills;
and re-vegetation, where practicable.
A pad will remain in the Construction stage until it is determined that no more active construction
is planned in the immediate future at the site, after which the pad will be moved to the Completed
stage or Interim stage.
Completed
After a pad is constructed and no additional construction is planned in the immediate future, a pad
is prepped for the Completed stage. The inspection schedule and details for Completed sites can
be found in Section 8.2. A site in the Completed stage has not the slopes reseeded yet due to
seasonal conditions, but is otherwise prepped for final stabilization.
Stormwater BMPs in place during the Completed stage generally include most or all of the BMPs
utilized during construction, and generally divert runon stormwater, contain sediment discharges
and filter stormwater. Additional long-term stabilization BMPs may be added to slopes and other
disturbed areas depending on the planned length of time between the location’s Construction stage
and Interim Stabilization stage, depending largely on when the next seeding season is (spring or
fall). Slope stabilization BMPs include mulching, tacking, blanketing, armoring and terracing.
Mulching BMPs may include various flexible growth medium products, blown and crimped straw,
and chipped branches or brush. Site specific mulches can be found on the site maps located in
SWIM database (see Appendix C for SWIM access and navigation instructions).
Disturbed areas reasonably needed for production operations that do not require restoration and
revegetation in accordance with COGCC Rule 1003.e will not be immediately revegetated, but will
be stabilized as stabilized unpaved surfaces. The term “stabilized unpaved surfaces” includes dirt
road surfaces and the portions of the well pad surfaces that cannot be revegetated due to
operational necessity, but does not include slopes, ditches, and other areas where revegetation is
necessary. Stabilized unpaved surfaces will be prepared in such a way as to minimize erosion,
including constructing surfaces with crushed rock, road base, gravel, and/or compaction, and
utilizing insloping, outsloping and crowning grading techniques to prevent rilling.
For well pads, the initiation of the Completed stage generally coincides with the initiation of the
Well Development Phases outlined in Section 4.2.1.2. Supplementary structural and non-structural
BMPs may be added during the Completed stage to address any additional stormwater concerns
associated with the site’s current Well Development Phase. See Section 4.2.1.2 for more details.
7
A pad will remain in the Completed stage until seasonal conditions allow for reseeding of the
disturbed slopes. Seeding seasons occur in the spring after snow melt is completed and site slopes
are dry enough to support seeding equipment, and in the fall just prior to snowfall.
Interim Stabilization
A site enters the Interim Stabilization stage if the installation of all BMPs required for attaining
Final Stabilization have been installed, including the initial seeding of the disturbed slopes and
stabilization of all stabilized unpaved surfaces, but for which the revegetation has not yet achieved
70% of pre-disturbance levels. If the site is a well pad the Interim Stabilization stage may also
include reducing the size of the pad to a smaller working area that will be needed for long-term
production and ongoing routine maintenance of the well(s), depending on whether or not the pad
will be drilled again in the near future. Reduction of pad size is called interim reclamation, and
generally includes recontouring of the site, spreading of topsoil on recontoured areas and reseeding
those areas, and installation of BMPs that will be present during the life of the wells (see Section
7.0 for details on reclamation procedures). Interim reclamation generally isn’t initiated at a well
pad site until the site has reached the Production Well Development Phase (see Section 4.2.1.2).
Sediment discharge, produced fluids and small amounts of equipment operational lube or fuel or
corrosion inhibitors or other chemicals are potential pollutants of concern during this stage of
construction. As indicated in the Production Well Development Phase (Section 4.2.1.2), the
presence of tanks for storage of produced fluids will require implementation of an SPCC plan to
prevent and control possible leaks from those tanks. In addition, secondary containment will be
provided for any tanks storing chemicals that are utilized during the life of the wells.
If the site undergoes interim reclamation, temporary BMPs may need to be installed during
earthwork, as needed, to eliminate sediment, chemical or other non-stormwater related discharges
during regrading activities. Temporary BMPs utilized may include perimeter control and
temporary slope stabilization BMPs. The inspection schedule will change from monthly to every
14 days, including post-precipitation inspections (see Section 8.2), until the reclamation earthwork
is completed and all long-term stabilization BMPs are in place.
Long-term slope stabilization BMPs that may be utilized during this stage include revegetation,
mulching, tacking, blanketing, armoring and terracing. Seeding methods for re-establishing
vegetation usually include hydroseeding, drill seeding or broadcast seeding. Selection of seed
mixes is coordinated with the landowners and/or selected based on soil and climate conditions and
desired vegetative properties. Site specific seed mixes can be found on the site maps located in the
SWIM database (see Appendix C for SWIM access and navigation instructions). Mulching BMPs
may include various flexible growth medium products, blown and crimped straw, and chipped
branches or brush.
8
Final Stabilization
Final stabilization is reached when all ground surface disturbing activities at the site have been
completed, and uniform vegetative cover has been established with an individual plant density of
at least 70 percent of predisturbance levels, or equivalent permanent, physical erosion reduction
methods have been employed.
Permit coverage will be needed for any areas undergoing disturbance as required under the field-
wide permit. Once stabilization is achieved, defined as uniform vegetative cover established with
a density of at least 70 percent of pre-disturbance levels, permit coverage under the CDPHE for the
well pad and associated roads and pipelines may be inactivated if all other conditions of the permit
are met (See Section 7.3 for more details).
Returned
The Returned stage applies to sites that have been returned to the landowner and are effectively
removed from coverage under this permit. Returned sites may be reclaimed to various levels,
depending on the landowner’s wishes and the original land use.
Some landowners refuse to allow additional stormwater work or reclamation on their property and
have effectively prohibited access to stormwater and reclamation crews. Depending on their level
of cooperation, these landowners may or may not have signed a contract or the CDPHE
“Construction Transfer Form” stating that they will assume all responsibilities related to this
stormwater permit for the site in question. With uncooperative landowners, all efforts are made by
Noble to continue stormwater and reclamation work or to have the landowner contractually assume
permit responsibilities for the site. If these efforts fail, stormwater inspections, BMP maintenance
and reclamation work is ceased at the site until the landowner again allows this work to continue.
4.2.1.2 Well Development Phases
The development of natural gas wells is generally accomplished in three distinct well development
phases. These phases include Well Drilling, Well Completion, and Production. Specific BMPs
will be utilized to address the unique aspects of each phase and are in addition to the construction
BMPs already in place on the pad, and may change over time according to the current activities on
the well pad.
Well Drilling
The Well Drilling phase includes the drilling of one or more natural gas wells at each location.
The basic activities associated with the drilling phase include:
Mobilization of the drilling rig and associated equipment, including generators and
drilling-mud handling equipment – in some instances a smaller drilling rig may be used
9
to drill the initial stages of each well prior to the larger drilling rig mobilizing to the
location
Installation of storage, office and housing trailers
Storage of downhole chemicals, fuels and lubricants
Installation of potable water tanks and sewage-handling equipment (e.g., portable
toilets or sewage vaults)
Well drilling activities including the installation and cementing of well casing
Demobilization of the drilling rig and all other equipment at the completion of this
phase
Sediment discharge, unused and used chemicals and drilling water/mud are potential pollutants
of concern during this phase of construction. During drilling, drilling mud and water will be
used to maintain appropriate downhole pressures and lubrication. Unused fresh water and mud
chemicals will be stored on the pad. Used materials will either be discharged to the reserve pit or
captured in tanks for closed-loop drilling processes. Petroleum products are used for the
duration of the drilling process to fuel or lubricate equipment and include: fuel, gear oil,
hydraulic oil, brake fluid, and grease. Materials to be used to cement casing placed in the well
may also be stored and prepared on location or may be transported to the site.
Structural BMPs specific to the drilling phase may be installed to control discharges associated
with specific pieces of equipment or facilities for storage of materials on the location. Such
BMPs may include non-construction related stormwater diversions; secondary containment
structures around chemical storage areas and equipment, such as berms, collection ditches and/or
water bars; and water bars at the pad entrance. With the presence of chemicals onsite, some
active BMPs may be temporarily disabled during the drilling phase to prevent unmonitored SW
discharges from occurring. Appropriate replacement BMPs will be installed, if needed.
Certain non-structural BMPs may be utilized during this phase to assist in managing stormwater
compliance such as limiting traffic, conducting training and inspections, providing equipment and
procedures to prevent spills of sewage or other materials, and ensuring that good material
management practices are being implemented. Procedures will also be implemented for prompt
containment and remediation of any spills that may occur during the drilling phase.
As equipment is demobilized at the completion of this phase, the well pad and surrounding areas
will be carefully inspected to identify any spills or leaks that may have occurred so that those areas
can be remediated prior to initiation of the well completion phase. All structural BMPs will also
be inspected and maintained during the demobilization of equipment to insure that any damage to
these BMPs resulting from demobilization is promptly repaired.
10
Well Completion
The Well Completion phase includes hydraulic fracturing (fracing), cementing, and other
processes that stimulate the well and prepare it for production. The basic activities that are
conducted during this phase include:
Mobilization of equipment required for well completion
Storage of downhole chemicals, fuels and lubricants
Installation of potable water tanks and sewage-handling equipment (e.g., portable
toilets or sewage vaults) or continued maintenance of such equipment installed during
the drilling phase
Fracing and other well-stimulation processes
Drill out of any plugs placed during well completion with a work-over rig
Flowback of the well to remove frac water, sand and other impurities
Demobilization of equipment when this phase has been completed
Several temporary facilities/structures will be placed on site during this phase. These will
include: frac trucks, storage and office trailers, generators, and frac tanks. During completions,
certain chemicals may be used to stimulate the formation for the extraction of natural gas.
Unused water and chemicals will be stored on the pad. Used water will be stored in the reserve
pit or cleaned up and recycled in other operations. Sediment discharge, unused and used
chemicals and frac water are potential pollutants of concern during this phase of construction.
Structural BMPs specific to the well completion phase may be installed to control discharges
associated with specific pieces of equipment or facilities for storage of materials on the location.
Such BMPs may include non-construction related stormwater diversions; secondary containment
structures around chemical storage areas, tanks and equipment, such as berms, collection ditches
and/or water bars; and water bars at the pad entrance. With the presence of chemicals onsite,
some active BMPs may be temporarily disabled during the drilling phase to prevent unmonitored
SW discharges from occurring. Appropriate replacement BMPs will be installed, if needed.
Certain non-structural BMPs may be utilized during this phase to assist in managing stormwater
compliance such as limiting traffic, conducting training and inspections, providing for equipment
and procedures to prevent spills of sewage or other materials, and ensuring that good material
management practices are being implemented. Procedures will also be implemented for prompt
containment and remediation of any spills that may occur during the completion phase.
As equipment is demobilized at the completion of this phase, the well pad and surrounding areas
will be carefully inspected to identify any spills or leaks that may have occurred so that those areas
can be remediated prior to initiation of the production phase. All structural BMPs will also be
inspected and maintained during the demobilization of equipment to insure that any damage to
these BMPs resulting from demobilization is promptly repaired.
11
Production
The Production phase includes the installation of long-term facilities such as permanent well
heads, storage tanks, gas processing equipment, flow measurement equipment, and any
associated flow lines needed to produce natural gas from the formation. An actively producing
gas well produces fluid phase along with gas phase products. Storage tanks may be placed on
site during this phase to hold any produced water and/or fluid phase hydrocarbons (condensate).
Sediment discharge, produced fluids, and small amounts of equipment operational lube or fuel or
corrosion inhibitors or other chemicals are potential pollutants of concern during this phase of
construction. The installation of tanks for storage of produced water and/or condensate triggers
the requirement to include the site under the Spill Prevention Control and Countermeasure
(SPCC) plan. Any stored chemical, including produced fluids, are required to have appropriate
secondary containment.
Structural BMPs specific to the Production phase may be installed to control discharges
associated with specific pieces of equipment or facilities for storage of materials on the location.
Such BMPs may include non-construction related stormwater diversions; secondary containment
structures around tanks and equipment, such as earthen berms or steel containment. BMPs that
may have been temporarily disabled during the drilling or well completion phases to prevent
unmonitored SW discharges from occurring may be re-enabled during this phase as there is less
risk of chemical discharge.
Certain non-structural BMPs may be utilized during this phase to assist in managing stormwater
compliance such as limiting traffic, conducting training and inspections, providing for equipment
and procedures to prevent spills of sewage or other materials, and ensuring that good material
management practices are being implemented. Procedures will also be implemented for prompt
containment and remediation of any spills that may occur during the production phase.
4.2.2 Access Roads and Pipeline Right-of-Way Construction
Access roads and pipeline right-of-ways (ROWs) offer unique challenges for construction and
stormwater management due to their linear nature and ability to intersect large drainage areas.
For these main reasons, stormwater for these two construction activities is generally managed
differently than for well and facility pads. This section offers more detail on how stormwater is
managed for access roads and pipeline ROWs.
4.2.2.1 Access Road Construction
The development of natural gas wells also requires the construction of access roads. Access road
construction is generally accomplished by using traditional cut and fill techniques but may also
require blasting and other techniques. Size and maintenance requirements for each road are based
on road location, traffic level and/or landowner’s stipulations. Extra care and planning is taken to
identify and protect sensitive areas, such as stream or drainage crossings, prior to construction.
12
BMPs will be implemented before and during construction of roads and will be maintained
throughout the lifetime of the road or until stabilization reaches a point that they are not needed.
Structural BMPs used during road construction and maintenance will include, at a minimum,
cut and fill slope stabilization and revegetation;
diversion of non-project water through armored culverts or other appropriate BMPs;
road surface stabilization techniques, including utilizing crushed rock, road base, gravel,
paving and/or compaction;
grading, including insloping, outsloping and crowning;
and collection and management of onsite stormwater through ditches, drainage dips, waterbars,
dams, traps, and perimeter controls.
BMPs will be selected and placed with consideration given to the unique aspects of each access
road.
Seeding methods for re-establishing vegetation on cut and fill slopes usually include hydroseeding,
drill seeding or broadcast seeding. Selection of seed mixes is coordinated with the landowners
and/or selected based on soil and climate conditions and desired vegetative properties. Site
specific seed mixes can be found on the site maps located in the SWIM database (see Appendix C
for SWIM access and navigation instructions). Mulch or blanketing BMPs may or may not be
added to reseeded areas in coordination with landowner stipulations and/or slope conditions.
Mulching BMPs may include various flexible growth medium products, blown and crimped straw,
and chipped branches or brush.
Certain non-structural BMPs may be utilized to assist in managing stormwater compliance such as
limiting traffic while wet or muddy conditions exist, planning for and proper maintenance during
winter conditions, sediment tracking controls and contractor education.
Once stabilization is achieved on the cut and fill slopes and surface of an access road, an access
road may be removed from permit coverage. Stabilization is defined as uniform vegetative cover
established with a density of at least 70 percent of pre-disturbance levels OR successful installation
of an effective stabilized unpaved surface or other long-term stabilization BMP (See Section 7.0
Final Stabilization for more details).
4.2.2.2 Pipeline Construction
The development of natural gas wells also requires the construction of pipelines used to transmit
natural gas and other related fluids. Pipeline construction is generally accomplished by trenching.
The area of disturbance for each pipeline is determined by location and pipeline size, and is
generally referred to as the right-of-way (ROW). Extra care and planning will be taken to identify
and protect sensitive areas, such as stream or drainage crossings, prior to construction.
13
BMPs will be implemented before and during construction of pipelines and will be maintained
throughout the lifetime of the pipeline or until stabilization reaches a point that they are not
needed. Structural BMPs used during pipeline construction and maintenance will include, at a
minimum, slope stabilization; diversion of non-project water through armored drainage or other
appropriate BMPs; water bars; traps; and perimeter controls. BMPs will be selected and placed
with consideration given to the unique aspects of each ROW disturbance.
All disturbed areas along the ROW will be reseeded immediately or once the area is not needed for
the project. Seeding methods for re-establishing vegetation usually include hydroseeding, drill
seeding or broadcast seeding. Selection of seed mixes is coordinated with the landowners and/or
selected based on soil and climate conditions and desired vegetative properties. Site specific seed
mixes can be found on the site maps located in the SWIM database (see Appendix C for SWIM
access and navigation instructions). Mulch or blanketing BMPs may or may not be added to
reseeded areas in coordination with landowner stipulations. Mulching BMPs may include various
flexible growth medium products, blown and crimped straw, and chipped branches or brush.
Certain non-structural BMPs may be utilized to assist in managing stormwater compliance such as
limiting traffic along the ROW, especially if wet or muddy conditions exist, route planning to
minimize runoff potential, minimizing the disturbed areas, and contractor education.
Once stabilization is achieved, defined as uniform vegetative cover established with a density of at
least 70 percent of pre-disturbance levels, a pipeline ROW may be removed from permit coverage
(See Section 7.0 Final Stabilization for more details). However, if petroleum hydrocarbons or
other chemicals impact stormwater as a result of industrial activities onsite, all or portions of the
ROW will maintain permit coverage and ensure SPCC plan BMPs are maintained.
4.3 Area Disturbed
The specific area disturbed at each individual pad site, access road or pipeline ROW is listed on
the respective site map in the SWIM database (See Appendix C for SWIM access and navigation
instructions). A total of all current acreage disturbed under this permit is also kept in the SWIM
database.
4.4 Soil Description
Soils in the project area consist of Cochetopa loam, Bucklon-Inchau loams, Nihill channery
loam, Potts loam, and Potts –Ildefonso complex. The elevation for these soil types range from
5,000 to 9,500 feet above mean sea level. The slopes typically range from 1 to 50 percent. Site
specific soil descriptions can be found on the site specific narratives, located in the SWIM
database (see Appendix C for SWIM access and navigation instructions).
The Battlement Mesa area consists of the following soil types:
Cochetopa loam, 9 to 50% slopes – is on mountainsides and alluvial fans. The native vegetation
mainly consists of Gamble oak, bromes, and elk sedge. The permeability is slow, and the
14
available water capacity is high. Runoff is slow, and the hazard of water erosion is severe.
Elevations range from 7,000 to 9,000 feet above mean sea level.

native vegetation mostly consists of wheatgrass, needleandthread, and sagebrush. The
permeability is moderately rapid, and the available water capacity is low. Runoff rate is slow,
and the hazard of water erosion is moderate. Elevations range from 5,000 to 6,500 feet above
mean sea level.
Potts loam, 6 to 12% slopes – is formed on mesas, benches, and sides of valleys. The native
vegetation mostly consists of wheatgrass, needleandthread, and sagebrush. The permeability is
moderate, and the available water capacity is high. Runoff rate is medium, and the hazard of
water erosion is severe. Elevations range from 5,000 to 7,000 feet above mean sea level.
Potts–Ildefonso complex, 12 to 25% slopes – is formed on mesas, alluvial fans, and sides of
valleys. The native vegetation mostly consists of wheatgrass, needleandthread, and sagebrush.

soil is moderately rapid, and the available water capacity is low. Runoff rate is medium, and the
hazard of water erosion is moderate. Elevations range from 5,000 to 6,500 feet above mean sea
level.
The Rulison area consists of the following soil types:
Vale silt loam, 6 to 12% slopes – is formed on mesas, benches, and alluvial fans. The native
vegetation mostly consists of wheatgrass, needleandthread, muttongrass, and sagebrush. The
permeability is moderate, and the available water capacity is high. Runoff rate is medium, and
the hazard of water erosion is moderate. Elevations range from 5,000 to 7,200 feet above mean
sea level.
Morval loam, 3 to 12% slopes – is formed on mesas and sides of valleys. The native vegetation
mostly consists of neadleandthread, wheatgrass, sagebrush. The permeability is moderate, and
the available water capacity is moderate. Runoff rate is slow, and the hazard of water erosion is
slight. Elevations range from 6,500 to 8,000 feet above mean sea level.
4.5 Vegetation Description
A vegetation description for each Piceance Basin facility is provided on each site map, including
pre-disturbance vegetation type and estimated basal percentage. Current site maps are located in
15
the SWIM database (see Appendix C for SWIM access and navigation instructions). Vegetation
group types found in the Piceance Basin are categorized as follows:
Low-Elevation Salt-Desert Scrub/Basin Big Sagebrush
Pinion-Juniper Woodland and/or Mountain/Wyoming Big Sagebrush Shrubland
Mixed Mountain Shrubland, Including Oakbrush
Spruce-Fir Forest, Including Mountain Meadows
Agricultural Fields/Grassland
4.6 Description of All Potential Pollution Sources
The location and description of all potential pollution sources are discussed in detail in Section
6.1. A list of all down-hole chemicals used during the Well Drilling and Well Completion
phases are listed in Appendix B. Site specific pollution sources are described in the site specific
narratives and their locations depicted on the site maps, both found in the SWIM database (see
Appendix C for SWIM access and navigation instructions)
4.7 Non-Stormwater Discharges
The following is a summary list of non-stormwater discharges which are allowed under the
stormwater permit:
Discharges from emergency fire-fighting activities or a fire hydrant
Landscape irrigation or return flow
Uncontaminated springs
Noble does not anticipate any non-stormwater discharges at the pad sites.
4.8 Receiving Waters
Receiving water bodies within the permitted area include unnamed tributaries of Wallace Creek,
Spring Creek, Bill and Pete Creek, Little Alkali Creek, Monument Gulch, Stone Quarry Gulch,
Dry Creek, Battlement Creek, Cache Creek, and Spruce Creek. The ultimate receiving water
body in the area is the Colorado River.
Information regarding the specific receiving waters and their respective distances from each site
are also found on the site maps and site specific narratives located in the SWIM database (see
Appendix C for SWIM access and navigation instructions).
The majority of Noble’s pads, pipeline ROWs or access roads do not intrude or encroach on any
wetland acreage. If a wetland is designated to be within a pad construction area, Noble will
obtain permits from Army Corp of Engineers, as appropriate.
5.0 SITE MAPS
Site maps are located on the SWIM web-based database, and are updated regularly to reflect
current site conditions (see Appendix C for SWIM access and navigation instructions). Site
maps are stored in Microsoft® Office Visio® format, and require Visio® to view. One site map
16
file exists for each site, with maps depicting the site conditions during each of the construction
stages (where applicable) on different “tabs” in the file. Additionally, every time a site changes
(BMPs, equipment, storage, etc. are changed onsite), even if the construction stage hasn’t
changed, a new revised site map is added to the file under a new tab with the revision date.
Historical site maps are never removed but are stored on different tabs in the same file for
reference and record-keeping.
Site maps generally include: pad construction site boundaries; ground surface disturbances; areas
of cut and fill; storage areas for building materials, equipment, soil, chemicals or waste; locations
of dedicated asphalt or concrete batch plants (if applicable); structural BMP locations; non-
structural BMP locations (as applicable); locations of springs, streams, wetlands or other surface
waters; wellhead locations; vegetation information and other pertinent site specifics.
Additional site specific information can be found on the site specific narratives, also located in
the SWIM database (see Appendix C for SWIM access and navigation).
6.0 STORMWATER MANAGEMENT CONTROLS
This section outlines the general potential pollutant sources in the Noble Piceance Field as well
as the BMPs utilized to mitigate them. Site specific information on these topics can be found on
the site specific narratives located in the SWIM database (see Appendix C for SWIM access and
navigation).
6.1 Identification of Potential Pollutant Sources
To identify, evaluate, and assess potential sources of stormwater runoff pollutants that may be at
a pad site, the following activities and pollutant sources are evaluated:
Disturbed and stored soils;
Vehicle tracking controls;
Management of contaminated soils;
Loading and unloading operations;
Outdoor storage activities, including chemicals;
Vehicle and equipment maintenance and fueling;
Dust or particulate generating processes or activities;
Routine maintenance activities;
On-site waste management practices;
Concrete truck washing;
Dedicated concrete and asphalt batch plants;
Non-industrial waste sources; and
Potential spills.
6.1.1 Disturbed and Stored Soils
Disturbed soil and excavated materials will be incorporated into fill slopes, or stored on or next
to the pad. Topsoil and other soils will be stockpiled separately, usually as diversion or
containment berms around the edges of the disturbance. Excavation in especially sensitive areas
may be conducted using special techniques as specified by the landowner/agency representative.
17
Materials excavated will be utilized as backfill when practical. An exception may be excess rock
generated by rock blasting excavation activities. In these areas, some select backfill materials
may be required to protect the project area. Excess rock may be pushed into rock filter dikes,
used in energy dissipation zones below culverts, constructed into rock check dams within grassed
swales, or distributed over a portion of the project area.
All cut slopes made in steep rolling terrain during construction will be re-graded and contoured
to blend into the adjoining landscape and natural drainage patterns will be reestablished.
Temporary workspace areas will be restored to approximate pre-construction conditions.
6.1.2 Vehicle Tracking Controls
Properly constructed roads and pads provide the best off-site tracking control. Roads and pad
surfaces are usually stabilized as unpaved stabilized surfaces, and utilize crushed rock, road base,
and/or soil compaction, as well as grading techniques like insloping, outsloping and crowning, to
control runoff, erosion and tracking. Additionally, access road entrances adjacent to paved
county roads are often graveled to prevent or minimize any off-site soil tracking from pad areas
or access roads. In some instances, cattle guards are used to drop off caked mud before the
vehicle exits the site area. In addition, minimizing site access during wet conditions, contractor
education, and other sediment control BMPs are utilized. Locations of vehicle tracking control
BMPs are specified on the individual site specific narratives and maps, found in the SWIM
database (see Appendix C for SWIM access and navigation instructions).
6.1.3 Management of Contaminated Soils
If contaminated soils are excavated at a Noble site, additional BMPs will be employed to ensure
containment of any stormwater runoff. Contaminated soils will either be disposed of offsite or
will be landfarmed onsite within a containment berm. Landfarm locations will be noted on site
maps and in site specific narratives, found in the SWIM database (see Appendix C for SWIM
access and navigation instructions).
6.1.4 Loading and Unloading Operations
The majority of loading and unloading activities occur during well drilling and well completion
activities. Well drilling and completion surfactants, friction reducers, dilute hydrochloric acid,
potassium chloride solutions, drilling mud, condensate, and other fluids are transported or
unloaded directly into the well from trucks, on site tanks, and/or the reserve pit. Dry drilling
mud components are contained in paper bags and are stacked on pallets which are unloaded
using a forklift or by hand. In the event of a spill, the SWMP material handling and spill
prevention procedures will be followed (see Section 6.2.4) as well as the procedures in Noble’s
Spill Prevention Control and Countermeasure (SPCC) plan, considered part of this SWMP.
Other activities include unloading of drill pipe, completion pipe (casing), and natural gas line
pipe, which are not potential pollution sources.
18
6.1.5 Outdoor Storage Activities
The most common substances that are stored on a pad area are: 1) fuel and lubricants used by
vehicles and construction equipment; 2) frac fluids (surfactants, friction reducers, hydrochloric
acid, and potassium chloride) used during well completion procedures; 3) production water from
the well; 4) produced crude oil and condensates; and 5) down-hole chemicals associated with
drilling procedures.
Down-hole chemicals during the drilling and completion well development phases are stored in
tanks and drums, or in bags on pallets for dry chemicals, and within secondary containment.
Response to spill incidents involving down-hole chemicals may require specialized training due to
health and safety concerns. For a list of down-hole chemicals used during development activities
please refer to Appendix B.
6.1.6 Vehicle and Equipment Maintenance and Fueling
As a general rule, Noble does not allow vehicle maintenance at its sites; however, minor repairs
in the field are occasionally allowed. Additionally, fueling of construction equipment is
occasionally performed at some construction locations. Refueling and lubrication of vehicles
and equipment will be conducted a minimum of 100 feet from flowing streams and wetlands.
Any spills will be promptly remediated and contaminated materials will be hauled off-site and
disposed of/recycled properly. Quantities of fuel and lubricates will be limited to “as-needed”
for the immediate operations underway.
6.1.7 Dust or Particulate Generating Processes or Activities
Dust and/or particulates generated from vehicle traffic on graveled access roads may produce
fugitive emissions. Dust and particulate generation is at its highest during dry and hot times of
the year. If dust from vehicle traffic on graveled access roads becomes significant, dust
suppression procedures will be implemented that include road watering or the application of dust
suppressants.
Magnesium chloride solution or other chemical dust suppressants may be applied during the
summer to unpaved roads to order to reduce fugitive dust generation. Magnesium chloride
solution is used in the winter for roadway deicing and in the summer for dust suppression by
county and state government entities. The solution is typically delivered to the site by
contractors in DOT approved tanker trailers and generally is quickly applied to the road surface.
Occasionally, depending on work site conditions, the tanker trailers may be staged along the road
until ready for application (typically no longer than overnight).
6.1.8 Routine Maintenance Activities
Routine maintenance activities involving fertilizers, detergents, fuels, solvents and oils are not
completed at the Noble pad sites. Herbicides will be applied annually in some areas to control
noxious weeds. Herbicide application will always be conducted by certified and trained
individuals, and with consideration for runoff potential to nearby surface waters.
19
6.1.9 On-site Waste Management Practices
All waste from materials imported to the construction site are placed in appropriate containment
and then removed for disposal/recycling to an appropriate licensed disposal/recycling facility.
No waste materials will be buried, dumped, or discharged to waters of the state.
6.1.10 Concrete Truck Washing
Concrete truck/equipment washing, including the concrete truck chute and associated fixtures
and equipment, is not conducted within the Noble Piceance Basin Drilling Program Area.
6.1.11 Dedicated Concrete and Asphalt Batch Plants
No dedicated concrete or asphalt batch plants are located within the Noble Piceance Basin
Drilling Program Area.
6.1.12 Non-Industrial Waste Sources
Cleanup of trash and discarded materials will be conducted at the end of each work day.
Cleanup will consist of patrolling the roadway, access areas, and general work areas in order to
pick up trash, debris, scrap, or other discarded materials.
All waste from materials imported to the construction site are placed in appropriate containment
and then removed for disposal/recycling to an appropriate licensed disposal/recycling facility.
This also includes sanitary sewage facilities (typically portable). No waste materials will be
buried, dumped, or discharged to waters of the state.
6.1.13 Potential Spills
Spills or leaks will be handled by Noble personnel or contractors, according to the Noble’s Spill
Prevention Control and Countermeasure (SPCC) plan, considered part of this SWMP. Materials
handling is discussed in detail in Section 6.2.4 of this plan.
All spills and releases of exploration and production waste or produced fluid exceeding 5 barrels
(210 gallons) including those contained within unlined berms, shall be reported in writing on the
COGCC Spill/Release Report Form 19 within 10 days of discovery of the spill.
All spills/releases that exceed 5 barrels (210 gallons) of exploration and production liquids/waste
shall be verbally reported to the COGCC at (303) 894-2100 within 24 hours of discovery.
Spills or releases of any size that impact or threaten to impact any waters of the state, residence
or occupied structure, livestock or public byway, shall be verbally reported to the COGCC as
soon as practical after discovery (COGCC Rule 906). If the spill may reach waters of the state
(which includes surface water, ground water and dry gullies or storm sewers leading to surface
water), it must also be reported immediately to the Colorado Department of Public Health and
Environment (CDPHE) at 1-877-518-5608.
20
Spills or releases of more than 25 gallons of refined petroleum crude oil products such as
gasoline, diesel fuel, oil, or derivatives of mineral, animal or vegetable oil shall be reported to the
state of Colorado Division of Oil and Public Safety at (303) 318-8547 within 24 hours.
A hazardous substance release in any amount which enters or threatens to enter waters of th e
state shall be reported to Colorado Department of Public Health & Environment (CDPHE).
For all information regarding material/waste management application, limitation, standards,
maintenance and inspection refer to the supporting document “Best Management Practices
(BMPs) for Stormwater Management,” material/waste management section.
6.2 Best Management Practices (BMPs)
BMPS for sediment and erosion control will be accomplished through a combination of
construction techniques, vegetation and re-vegetation, administrative controls, and structural
features. Typical configurations of structural controls discussed below and technical drawings
with references are provided in the Noble BMP Manual “Best Management Practices (BMPs) for
Stormwater Management,” considered part of this SWMP. BMP selection is guided by the
decision tree shown in Figure 11; however, the decision tree is only used as a guide and is
deviated from when deemed appropriate.
Structural and non-structural BMPs are discussed in the following sections.
6.2.1 Structural Practices for Erosion and Sediment Control
Structural practices primarily include physical attributes of a pad site, access road or pipeline
designed to reduce erosion and control stormwater or sediment movement.
6.2.1.1 Erosion Reduction and Control
Construction of a pad, access road or pipeline requires the removal of vegetative cover and
topsoil, thereby increasing peak flood flows, water velocity, and the volume of stormwater
runoff. An increase in water runoff volume and velocity results in increased erosion. Erosion
reduction and control will be accomplished by using all or combinations of various erosion
control methods. These methods include, but are not limited to the following:
Check Dam (CD)
A small dam constructed across a swale or drainage ditch which slows the velocity of a
concentrated flow within a channel. Check dams may be constructed using gravel, rock, and
straw bales, or wattles.
Culverts (C)
Culverts are typically used to move ditch water under the road or to direct stream flow under the
access road. Culverts are typically constructed out of concrete, steel, aluminum, or plastic pipe.
21
Diversion (D)
A diversion consists of a channel and dike or ridge constructed across the slope to collect and
divert runoff. The purpose of this practice is to divert excess surface water from one area to a
safe disposal location.
Drainage Dip (DD)
Drainage dips intercept and remove surface water from access roads, pads, facilities, pipelines,
and roadside ditches before the combination of water volume and velocity begin to erode.
Erosion Control Blanket (ECB)
Erosion control blankets are porous fabrics and are manufactured by weaving or bonding fibers
made from organic or synthetic materials. They are installed on steep slopes, over berms, or in
channels to prevent erosion during vegetation established.
Hydromulch (HM)
Hydromulch consists of applying a mixture of shredded wood fiber or a hydraulic matrix, and a
stabilizing emulsion or tackifier with hydromulching equipment, which temporarily protects
exposed soil from erosion by raindrop or wind.
Mulch Tackifier (MT)
An organic soluble powder adhesive used in the form of a water slurry to adhere native hay,
straw, Hydromulch, or seed to a surface and together.
Mulching (M)
Mulching is a temporary erosion control practice in which materials such as grass, straw, hay,
wood fibers or wood chips are placed on exposed or recently planted soil surfaces. Mulching
stabilizes soils by minimizing rainfall impact and reducing stormwater runoff velocity. When
mulching is used in combination with seeding, surface soils retain moisture, promote seed
germination and help insulate roots from extremes temperatures.
Revegetation (RV)
Revegetation involves planting seed to establish a vegetative cover on disturbed areas.
Revegetation reduces erosion and sedimentation by stabilizing disturbed areas in a manner that is
economical and adaptable to site conditions. It also reduces runoff volumes by increasing water
percolation into the soil, binds soil with roots, and protects soil from wind erosion. The permanent
seed mix, rate, application method, and supplemental materials will be selected by the
Revegetation contractor or the BLM representative for Federal sites.
Riprap (R)
22
Riprap is a layer of large, hard, angular stones used to protect soil from erosion in areas of
concentrated runoff. Riprap can also be used on slopes that are unstable because of seepage
problems.
Roadside Ditches (RSD)
Roadside ditches are channels constructed parallel to roads. The ditches convey concentrated
runoff of surface water from roads and surrounding areas to a stabilized outlet.
Slope Drain (SD)
A slope drain is a conduit extending the length of a disturbed slope and serving as a temporary
outlet for a diversion. Slope drains convey runoff without causing erosion on or at the bottom of
the slope.
Stabilized Construction Entrance (SCE)
A stabilized construction entrance is temporary stabilization of on-site roadway by placement of
gravel roadbase.
Stabilized Construction Roadway/Surface (SCR)
Stabilized construction roadways incorporate gravel surfacing and proper grading on access
roads, but are also incorporated on pad surfaces. Gravel surfacing may be used to cover soil in
areas of high traffic, such as, roads, facility areas, and areas near the well heads. Gravel
surfacing forms a layer that protects and minimizes soil erosion and vehicle soil tracking.
Grading involves reshaping the ground surface to planned grades as determined by an
engineering survey, evaluation, and layout. Grading provides more suitable topography for well
pads, pipelines, facilities and access roads and helps to control surface runoff, soil erosion, and
sedimentation during and after construction in these areas. Grading also includes road crowning
and sloping to properly route runoff off the access roads.
Surface Roughening (SR)
Soil surface roughening is a temporary erosion control practice often used in conjunction with
grading. Soil roughening involves increasing the relief of a bare soil surface with horizontal
grooves (corrugating) or tracks (tracking) using construction equipment. Slopes that are not fine
graded and that are left in a roughened condition can reduce erosion, trap sediment, and prepare
ground surfaces for seeding.
Terracing (T)
Slope construction with benches or terraces spaced at regular intervals perpendicular to the slope
which intercept and collect sheet flow and direct it to a stable outfall point.
Turnouts (TO)
23
Turnouts are used to effectively remove run-off water from the roadside ditch into well-
stabilized areas before it reaches a waterway.
Water Bar (WB)
A water bar is a ridge of compacted soil, loose rock, or gravel constructed across disturbed right-
of-ways and similar sloping areas.
Wind Erosion Control (WEC)
Consists of applying water or other dust palliatives as necessary to prevent or alleviate dust
nuisance generated by construction activities. Covering small stockpiles or areas is an
alternative to applying water or other dust palliatives.
Existing vegetation cover and topsoil are removed only where necessary for the operation of
equipment and construction of the pad. Trees and large shrubs that are not cleared from the pad
area will be protected from damage during construction by avoiding them with equipment. For
example, the blade of a bulldozer will be in a raised position except for designated areas.
Trees will be cut or trimmed only to facilitate clearing, grading, and safe installation of a pad.
Trees outside the area of disturbance will not be cut, but may have overhanging limbs trimmed,
if necessary.
6.2.1.2 Sediment Reduction and Control
The control and reduction of sediment contained in stormwater runoff will be accomplished by
the use of sediment containment systems. Sediment containment systems are hydraulic controls
that allow the detention of suspended particles via gravity, filtering or entrapment. Sediment
controls that will be used to mitigate and control sediments generated from the erosive transport
forces of stormwater during and after construction of a pad will include but will not be limited to
the following:
Berms (B)
A berm is a ridge of compacted soil located at the top or base of a sloping disturbed area to
contain or divert surface runoff. The purpose of a berm is to control runoff velocity, divert
onsite surface runoff to a sediment trapping or filtration device and/or divert clean water away
from disturbed areas.
Brush Barriers (BB)
A temporary sediment barrier constructed at the perimeter of a disturbed area from the residue
materials available from clearing and grubbing the site, and generally covered with filter fabric.
Culvert Protection (CP)
Culvert protection may be required at the inlet to the culvert (upstream side) and /or the outlet to
the culvert (downstream side). Inlet protection will reduce the velocity of stormwater flows and
thereby erosion and help protect the inlet structure. Outlet protection will also reduce the
24
velocity of stormwater flows and thereby prevent scouring at the culvert outlet, protect the outlet
structure, and minimize the potential for erosion downstream.
Filter Berm (FB)
A filter berm is temporary ridge made up of gravel, stone, or crushed rock. Filter berms are
placed along a level contour to slow, filter, and divert flows and act as an efficient form of
sediment control.
Sediment Trap (ST)
Sediment traps are intended to intercept, trap, and retain sediment from runoff while allowing
detained runoff to slowly drain, infiltrate, or both. They are usually installed in a drainage way or
other point of discharge from a disturbed area. This BMP is formed by excavating below grade
and/or constructing an earthen embankment with a protected spillway to slow the release of
runoff.
Straw Bale Barrier (SBB)
A straw bale barrier is a series of entrenched and staked straw bales placed on a level contour to
intercept sheet flows. The barrier reduces runoff velocity and filters sediment laden runoff from
small drainage areas of disturbed soil.
Vegetative Buffer (VB)
Vegetative buffers are areas of either natural or established vegetation that are maintained to
protect the water quality of neighboring areas. Vegetative buffers reduce stormwater runoff
velocity, prevent soil erosion, promote infiltration and act as a filter to remove sediment.
Wattles (W)
Straw or similar material, wattles or rolls are intended to intercept runoff, reduce flow velocity,
release runoff as sheet flow, and provide removal of sediment.
Silt Fence (SF)
Silt fences are used as temporary perimeter control structures that are designed to slow,
temporarily impound, and filter sediment laden water.
6.2.1.3 Detailed Structural Practices
The following structural and administrative site management practices are expected to reduce,
minimize and control erosion and sediment transport:
In order to minimize disturbances associated with installation of pads, level and gently
sloping terrain outside the construction project area will not be graded, except where
necessary.
25
To prevent tracking of sediment, mud and rocks onto public roads, portions of access
roads may be graveled, as appropriate. Other means such as track pads/angular rock or
cattle guards may be utilized, if appropriate.
Silt barriers (e.g. brush dams, rock filter dikes, silt fences, hay bales, straw wattles, or
water bars) will be installed, as needed, on down-gradient portions of project areas.
Side hill cuts (cut slopes) will be kept to a minimum to protect local resources while
providing a safe and stable plane for the efficient and safe use of equipment.
Where conditions warrant, erosion control structures such as berms, water bars, diversion
or collection channels, terraces, or culverts will be constructed to divert water away from
project areas. These control structures will also reduce soil erosion along and adjoining
areas disturbed during construction.
During construction near perennial streams, lakes or wetlands, the utilization of
sedimentation (detention) basins, silt fences, straw bales, or fabric filters may be
considered in order to prevent suspended sediments from reaching downgradient
watercourses, streams, lakes or wetlands.
Where appropriate, water bars or sediment filters, such as staked straw bales or silt
fences, will be constructed adjacent to crossings to reduce potential sedimentation in
streams or wetlands.
In areas that have steep slopes, water bars or runoff diversions may be installed.
Culverts inlet protection may include inlet aprons and rock armoring around the culvert
perimeter while below grade inlet sumps may be installed to enhance sediment
deposition. Outfall protection may include the use of a rock barrier to slow the discharge
of runoff water. Culvert pipe or outfall protection will be extended to the toe of the slope
on the discharge end.
During the reclamation of a pad, all cut and fill slopes in steep terrain will be graded and
contoured to blend into the adjoining landscape. Natural drainage patterns will also be
reestablished. When possible cut and fill slopes will be constructed so they are no steeper
than a 1 to 3 ratio.
Reclaimed pads may have a fence constructed around areas that have been seeded. These
fences will be installed in order to keep livestock and vehicles off reseeded areas.
The “Best Management Practices (BMPs) for Stormwater Management” manual is considered
part of this SWMP, and includes details and explanations on BMP installation procedures.
6.2.1.4 Implementation of Structural Practices
Structural BMPs will be installed according to the details in the “Best Management Practices
(BMPs) for Stormwater Management” manual, which is considered part of this SWMP, or will
be installed according to the specific engineered designs provided on the “New Site” tab of the
26
site maps (site maps are located in the SWIM database – see Appendix C for SWIM access and
navigation instructions).
The following sediment controls may be utilized at disturbed areas: vegetative buffers, brush
dams, rock filter berms, silt fences, straw bale dikes, water bars, sediment traps, sediment basins,
or equivalent sediment controls. These sediment control structures will be installed so as to
protect down gradient surface waters, wetlands and roads from sediment flow due to runoff from
a precipitation or snow melt event.
All graded surfaces, walls, dams and structures, vegetation, erosion and sediment control
measures and other protective devices identified in the site plan will be maintained, repaired, and
restored as necessary.
Table 2 contains a summary list of structural and non-structural BMPs used in each construction
stage and site type (pads, pipelines, and access roads).
6.2.2 Non-Structural Practices for Erosion and Sediment Control
Sediment and erosion control can be implemented via non-structural BMPs. Non-structural
BMPs are BMPs that are not engineered and are not “constructed”, but are capable of controlling
erosion and sediment just as effectively as structural BMPs.
Non-structural BMPs include physical BMPs in the field like tracking, revegetation, blanketing
and mulching. Pad sites can include a slope to the reserve pit or a buffer zone of natural
vegetation used as a non-structural BMP to inhibit sediment travel offsite and minimize the
footprint of the pad.
Non-structural BMPs also include administrative controls. Noble has implemented
administrative controls for stormwater management into pad site development, including
program oversight, construction site planning and management, and materials management, all
which are aspects of this SWMP.
6.2.3 Phased BMP Implementation
The stages of construction and phases of well development are linked to the implementation of
structural and non-structural BMPs. Descriptions of the construction stages and well
development phases, along with the applicable structural and non-structural BMPs for each stage
and phase are explained in Section 4.2.1 for well pads and Section 4.2.2 for access roads and
pipeline right-of-ways.
6.2.4 Material Handling and Spill Prevention
Hazardous materials and petroleum products used in construction of a pad include fuel and
lubricants for construction equipment and vehicles; small quantities of paints and solvents; water
or gel based frac fluids (surfactant, friction reducer, dilute hydrochloric acid, potassium chloride)
used during well completion; produced water; and crude oil/condensate. Material Safety Data
Sheets (MSDS) for materials to be used or that are produced, are maintained on Noble’s online
company database.
27
Refueling and lubrication of vehicles and equipment will be conducted a minimum of 100 feet
from flowing streams and wetlands. Any spills will be promptly remediated and contaminated
materials will be hauled off-site and disposed of/recycled properly. Quantities of fuel and
lubricates will be limited to “as-needed” for the immediate operations underway.
Additional information regarding material handling and spill prevention can be found in the
Noble Energy Piceance Basin Spill Prevention, Control and Countermeasure (SPCC) Plan
located with this SWMP.
6.2.5 Dedicated Concrete or Asphalt Batch Plants
Noble does not have or subcontract any dedicated concrete or asphalt batch plants for its pad site
development or construction in the Piceance Basin Drilling Program Area, nor will stormwater
encounter concrete or asphalt batch plant activities.
6.2.6 Vehicle Tracking Control
Noble will employ BMPs to minimize vehicle tracking. Further discussion on this topic is in
Section 6.1.2 of this SWMP.
6.2.7 Waste Management and Disposal, Including Concrete Washout
Waste disposal is further discussed in Sections 6.1.9 and 6.1.12 of this plan. Concrete washout
does not occur at Noble’s sites, and therefore, will not be a potential pollutant to stormwater.
6.2.8 Groundwater and Stormwater Dewatering
Construction dewatering may take place on a limited basis at Noble sites. The permit allows for
conditional discharge of construction dewatering to the ground (to infiltrate), however no
groundwater from construction dewatering can be discharged as surface runoff or to surface
waters. For large construction projects with planned dewatering activity, Noble will apply for a
separate dewatering permit from the state, as required.
7.0 FINAL STABILIZATION AND LONG-TERM STORMWATER MANAGEMENT
7.1 Reclamation
Whole or parts of sites are reclaimed in accordance with the COGCC 1000-Series Reclamation
Regulations. Interim reclamation at sites is initiated and completed in accordance with COGCC
Rule 1003 and final reclamation is initiated and completed in accordance with COGCC Rule 1004.
Please see the latest revision of the COGCC rules at http://cogcc.state.co.us.
Most disturbed areas not designated as working areas will be seeded and mulched during interim
or final reclamation to stabilize the soils. Table 1 contains approved seed mixtures and distribution
rates that are generally used in the Piceance Basin; however, Noble is not bound to using these
seed mixtures and application rates only. Seed mixtures and application rates are based upon
several factors including facility and well pad surrounding vegetation, desired vegetative
28
properties, soil types, elevation, surface relief and landowner specifications. Typical Pure Live
Seed (PLS) application rates are recommended to be doubled if seeding is performed by hydroseed
or broadcasting.
Well sites and areas which are identified as Bureau of Land Management (BLM) sites require
specific seed mix approval as directed by the Glenwood Springs, CO, Energy Office. BLM
reclamation requirements and policy revisions are updated periodically and can be reviewed in
Appendix D. For areas of disturbance that are on private land, the land owner may specify a
specific seed mix. Please refer to Table 1 and the site maps in the SWIM database for site-specific
seed mixes (see Appendix C for SWIM access and navigation instructions).
Disturbed areas reasonably needed for production operations that do not require restoration and
revegetation in accordance with COGCC Rule 1003.e will not be immediately revegetated, but will
be stabilized as stabilized unpaved surfaces. The term “stabilized unpaved surfaces” includes dirt
road surfaces and the portions of the well pad surfaces that cannot be revegetated due to
operational necessity, but does not include slopes, ditches, and other areas where revegetation is
necessary. Stabilized unpaved surfaces will be prepared in such a way as to minimize erosion,
including constructing surfaces with crushed rock, road base, gravel, and/or compaction, and
utilizing insloping, outsloping and crowning grading techniques to prevent rilling.
7.2 Post-Construction Structural Measures
Permanent water bars, culverts and/or other permanent structural measures may be installed on
steep slopes and at wetland and stream crossing boundaries.
After restoration and reclamation work is complete, required repairs to vegetation and erosion
and sediment control BMPs will be completed, as required.
7.3 Finally Stabilized
According to stormwater regulations, “finally stabilized means that all ground surface disturbing
activities at the site have been completed and all disturbed areas have been either built on, paved,
or a uniform vegetative cover has been established with an individual plant and a density of at
least 70 percent of pre-disturbance levels, and the vegetation cover is capable of providing
erosion control equivalent to pre-existing conditions, or equivalent permanent, physical erosion
reduction methods have been employed.”
A special condition exists for oil and gas pad sites regarding stabilized unpaved surfaces.
According to the CDPHE Stormwater Fact Sheet dated July 2007:
Areas developed as stabilized unpaved surfaces as needed for operation of the facility
after interim reclamation also qualify as “finally stabilized”. The term “stabilized
unpaved surfaces” includes dirt road surfaces and the portions of the well pad surfaces
that cannot be revegetated due to operational necessity, but does not include slopes,
ditches and other areas where revegetation is necessary. Stabilized unpaved surfaces
29
must be prepared in such a way as to minimize erosion, such as preventing rill erosion on
pad surfaces or roads.
Another special condition exists for pad sites within crop lands. According to the CDPHE
Stormwater Fact Sheet dated July 2007:
When portions of an oil and gas site are restored to crop land in accordance with
the COGCC rules, and returned to the control of the farmer following interim
reclamation, permit coverage is no longer required for those areas, and it is not
necessary for the oil and gas site to either stabilize or reassign permit coverage
for the area restored to crop land.
When this condition exists for a pad site, inspections will be discontinued and the site will be
removed from the stormwater construction permit program by submitting an Amendment Notice
Form to the CDPHE. Regulation of NEI’s stormwater management at the site will then fall
under Colorado Oil and Gas Conservation Commission (COGCC) rules and stormwater at the
location will be managed with NEI’s Stormwater Management Plan for Post Construction
Activities (SWMP-PCA).
8.0 INSPECTION AND MAINTENANCE PROCEDURES
8.1 Preventative Maintenance
Preventing stormwater from passing through pad areas where contamination may occur is a key
element of preventative maintenance. Another key element of preventative maintenance is the
routine inspection and repair of erosion and sediments control structures. Regular cleaning of
diversion ditches and other BMPs to keep them free of debris and sediment will be practiced.
Spillways and culvert systems will also be routinely cleaned and inspected. These maintenance
procedures will help to insure that the stormwater does not leave disturbed areas via unintended
channels.
The following preventive maintenance procedures will be implemented to reduce or eliminate
potential stormwater contamination sources that may exist on a site:
Storage containers, fuel tanks, and equipment used during construction activities should
be visually inspected routinely for obvious leaks. These inspections should be conducted
by site and contractor personnel as they perform their routine duties;
Drums will be properly labeled so an enclosed substance can be quickly identified.
OSHA-approved labeling and sign systems will be followed for all secondary containers;
Erosion damage to the earthen berms, outfalls, silt barriers, collection channel,
containment ponds, and any erosion and sediment control will be repaired as soon as
practical;
30
Areas of stained soil will be inspected in order to identify the sources of the staining.
Contaminated soil will be removed and properly disposed;
Energy dissipating material, such as riprap, cobbles or gravel will be placed, or existing
materials will be utilized at the stormwater outfalls to prevent erosion damage. Barrow
ditches should be free from vegetation and debris which may cause impounding of
stormwater; and
Stormwater management structures will be cleared of debris and repaired when
necessary; and surface runoff controls such as curbing, culverts, and ditches will be used
to control runoff.
8.1.1 Good Housekeeping
In accordance with BMPs that provide procedures to eliminate contamination, and direct, divert,
and contain stormwater, Noble has implemented a number of housekeeping practices. These
practices will help prevent soil sediment, trash, and toxic or hazardous substances from entering
navigable waters.
Housekeeping practices include regular cleaning, organization and maintenance of pad
equipment and erosion and sediment control structures throughout the project. Areas where
chemicals are stored and used at the project are stored in weather-proof buildings or containers
and/or contain secondary containment to prevent stormwater contact or runoff. These areas
include producing pads that typically consist of wellheads, separator units, dehydration units, and
300-barrel capacity aboveground stock tanks.
The following items will be addressed in order to maintain a clean and orderly pad during the
development, production, and abandonment phases of work:
Inspect pad areas routinely;
Correct deficiencies noted during inspections;
Clean and maintain stormwater management structures and components;
Routine trash collection and proper disposal;
Familiarize employees and contractors with spill clean-up equipment and storage
locations; and
Familiarize employees and contractors with good housekeeping procedures and pad
pollution prevention procedures.
8.1.2 Material Storage
The following good housekeeping practices will be followed at the material storage areas:
31
Storage containers will be stored away from direct traffic to prevent accidents. They will
also have proper labels;
Dumpsters and trash receptacles will be enclosed in order to prevent the dissemination of
refuse;
Storage areas will be kept free of refuse;
Chemical substances used at pads will be properly labeled and will have proper spill
containment; and
Chemical substance containers will be clearly labeled with an MSDS kept on file.
8.1.3 Waste Removal
All waste from materials imported to the construction site will be removed for disposal/recycling
to an appropriate licensed disposal/recycling facility, including sanitary sewage facilities
(typically portable). No wastes of imported materials shall be buried, dumped, or purposely
discharged to waters of the state. There are no other pollutant sources from areas other than
construction areas.
8.2 Inspections
To meet the requirements of CDPHE Stormwater General Permit No. COR-039527, inspection
and maintenance of erosion and sediment controls must occur during the construction project.
Continued inspection and maintenance is required for specific structures after construction is
completed. As of August 2008, Noble utilizes the SWIM database to report and record the
results of stormwater inspections, BMP installations, and repairs/maintenance. A complete list
of active inspection locations, site maps and site specific stormwater BMPs are provided in the
SWIM database. Please refer to Appendix C for more information on how to access and
navigate the SWIM database.
The inspection program includes the following:
1. A trained and qualified person familiar with the SWMP and stormwater controls conducts
facility inspections and enters inspection results into the SWIM database.
2. Inspections cover these areas:
· Evidence of surface erosion for disturbed areas;
· Material and chemical storage areas;
· Best Management Practices (BMPs);
· Surface water diversions and downgradient areas;
· New access roads and ditches; and
· Locations where vehicles enter or exit the site.
32
3. Inspections occur at least once every 14 calendar days and after a precipitation events or
snowmelt events that cause surface erosion.
4. Permanently stabilized areas are inspected at least once per month.
5. A physical log of inspections has been completed for all inspections prior to August 2008
and is located in Noble’s Rifle, Colorado, office for a minimum of three years.
Inspections occurring after August 2008 are recorded and maintained electronically in the
SWIM database. Access to the SWIM database and directions for its navigation are
reviewed in Appendix C.
6. Inspections are not required for disturbed areas when snow cover exists over the entire
site for an extended period as long as melting conditions do not exist.
7. Water quality is visually assessed for all receiving streams and discharge areas during
each inspection, if present.
8. Disturbed areas and material storage areas that are exposed to precipitation are inspected
for evidence of pollutants entering nearby drainages.
9. Check dams, wattles, and other BMPs are inspected for evidence of deterioration, under-
cutting, and build up of sediment. Sediment needs to be removed when it has built up
one-third to one-half the height of the BMP structure.
10. Roads used for vehicle access are inspected for evidence of off-site sediment transport.
11. The SWMP is modified, as necessary, whenever there is a change in design, construction
or operation that changes the potential for pollutant discharge to waters of the state.
12. An electronic inspection report summarizing the scope of the inspection, the name of the
person conducting the inspection, date of inspection, and observations relating to the
implementation is prepared and stored electronically utilizing the SWIM database.
Access to the SWIM database and directions for its navigation are reviewed in Appendix
C.
13. Actions taken to correct deficiencies associated with an inspection are recorded in the
SWIM database, including the date the deficiency was corrected, the company
responsible for the correction, and correction comments. Access to the SWIM database
and directions for its navigation are reviewed in Appendix C.
14. If no deficiencies are found during the inspection, or when all deficiencies relating to an
inspection have been corrected, the report contains a certification statement and an
electronic signature that the site is in compliance with the SWMP and the General Permit.
33
Personnel performing facility inspections for access roads, pipeline right-of-ways, well pads or
other operational facilities will record site conditions in the SWIM database. When deficiencies
are discovered, work orders are generated and reviewed by Noble to direct designated
subcontractors to perform maintenance or replacement of existing BMPs, or installation of
additional BMPs. Maintenance will include prompt adjustments and repairs to erosion and
sediment control structures that are found to be performing inadequately or deteriorating. Signs of
rill or gully surface erosion shall be repaired as quickly as practical. New BMP installations will
be in accordance with this SWMP and the BMP manual Best Management Practices for
Stormwater Management, considered part of this SWMP.
8.2.1 14-day Inspection/Active Construction Stage
During the construction stage, the inspection frequency for Noble sites is at least every 14 days
and after any precipitation or snowmelt event that causes surface erosion.
The pad perimeter, disturbed areas, and any stored materials that are exposed to precipitation will
be inspected for evidence of, or the potential for pollutants to enter the drainage system. Erosion
and sediment control systems that are identified on the electronic site-specific SWMP Inspection
Report (in the SWIM database) will be inspected to ensure that they are in good condition and
operating properly (see Appendix C for SWIM access and navigation instructions).
8.2.2 Monthly Inspection/Completed Stage
For sites or portions of sites that meet the following criteria, but final stabilization has not been
achieved due to a vegetative cover that has not become established, Noble will make a thorough
inspection of their stormwater management system at least once every month, and post-storm
event inspections are not required. This reduced inspection schedule is only allowed if:
i) all construction activities that will result in surface ground disturbance are completed (Note:
only construction activities that result in a disturbance of the ground surface must be completed.
Construction activities that can be conducted without disturbance of the ground surface, such as
certain well completion activities, would not prohibit a site from otherwise);
ii) all activities required for final stabilization, in accordance with the SWMP, have been
completed, with the exception of the application of seed that has not occurred due to seasonal
conditions or the necessity for additional seed application to augment previous efforts; and
iii) the SWMP has been amended to indicate those areas that will be inspected in accordance
with the reduced schedule allowed for in this paragraph.
8.2.3 Monthly Inspection/Interim Stabilization Stage
For sites that meet the conditions of Section 8.2.2 and the slopes of the site have been seeded for
revegetation, the site is considered to be in the interim stabilization stage and is also eligible for
the same reduced inspection schedule as for sites in the completed stage.
34
8.2.4 Final Stabilization Stage
When a pad site has reached final stabilization, it will be removed from the CDPHE stormwater
permit by submitting an Amendment Notice Form to the CDPHE. Regulation of NEI’s
stormwater management at the site will then fall under Colorado Oil and Gas Conservation
Commission (COGCC) rules and stormwater at the location will be managed with NEI’s
Stormwater Management Plan for Post Construction Activities (SWMP-PCA).
8.2.5 Winter Conditions
Inspections will not be required at pads, access roads and pipeline right-of-ways where snow
cover exists over the entire site for an extended period, as long as melting conditions and
construction activities do not exist at the site. Sites are generally assumed in compliance if
BMPs are not visible due to snow cover, unless previous repairs or maintenance issues are still
outstanding. Snow covered sites without open repairs are recorded as “In Compliance” on the
associated stormwater inspection reports maintained in the SWIM database (see Appendix C for
SWIM access and navigation instructions). The beginning snow cover dates, dates of
construction activity and dates when melting conditions began are recorded for each site on the
inspection reports where the snow cover inspection exclusion is utilized.
8.2.6 Precipitation Event Inspections
Active site inspections of sites in the Construction stage will be conducted within 24 hours after
a precipitation or snowmelt event that causes surface erosion. If no construction activities will
occur at a pad site following a storm event, post-storm event inspections will be conducted prior
to re-commencing construction activities, but no later than 72 hours following the storm event.
Surface erosion generally occurs when precipitation or snowmelt results in surface water flow.
If the precipitation infiltrates, then no inspection is required. In order to determine if surface
erosion or surface water flow resulted from a precipitation or snowmelt event, pumpers and other
field personnel are consulted immediately following a precipitation event as to the field
conditions in each of the areas (Rulison, South Grand Valley and Rulison). If field personnel
observe new erosion or BMPs that need maintenance following a precipitation event, post-
precipitation stormwater inspections are initiated immediately.
9.0 EMPLOYEE TRAINING
Noble will inform and train employees who are involved with SWMP activities, including
stormwater inspectors, stormwater administrator(s), BMP contractors, construction foreman and
BMP designers. Training will be conducted on an as-needed basis and will cover information
and procedures contained in the SWMP as described below. A Training Log can be found in
Appendix E recording the training dates and attendees.
The following topics are presented and discussed during SWMP training:
Introduction to CDPS Stormwater Permit;
Stormwater regulations;
Purpose of stormwater permit;
Requirements of stormwater permit;
35
Components of the SWMP;
Identification of potential pollutant sources;
BMPs and proper construction;
Preventative maintenance;
Good housekeeping;
Inspections and maintenance; and
Record keeping (SWIM database purpose and navigation).
10.0 RECORD KEEPING
The following record keeping procedures are implemented in order to provide accurate and
complete documentation of events associated with the stormwater management program.
Routine inspections will include the 14-day, monthly, and post precipitation event inspections.
Stormwater related inspection reports, site maps, and site narratives are maintained electronically
in the SWIM database after August 2008 (see Appendix C for SWIM access and navigation
instructions). Prior to this date, inspection reports and site maps are maintained in hard copy
form. All stormwater related records will maintained by Noble for a minimum of three years.
Site-specific records will be kept a minimum of three years from final stabilization.
11.0 SWMP REVIEW/CHANGES
Noble will amend the SWMP whenever there is a significant change in design, construction,
operation, or maintenance which has a significant effect on the potential for the discharge of
pollutants to water of the state, or if the SWMP proves to be ineffective in achieving the general
objectives of controlling pollutants in stormwater discharges associated with pad activities. The
SWMP is considered a “living document”.
