Conn Creek 4-lnch Gas-Lift Re pl aceme nt Pip eline
Conn Creek 4-Inch Gas-Lift Replacement Pipeline
OXY USA WTP LP
Minor Grading Permit Application Narrative
OXY USA WTP LP (OXY) is pursuing a Minor Grading Permit for the Conn Creek 4-lnch Gas-Lift
Replacement Pipeline (CC4 Pipeline) in Garfield County. Approximately 6,6 70 square feet will be
graded within an existi ng ROW. The proposed site is located on private property, owned by OXY
USA WTP LP, approximately 12 miles north of De Beque, Colorado. The pipeline will not require a
land use change permit. The pipeline's main function will be to transfer high pressure natural gas to
increase natural gas production on existing wells.
1.1 Description
The site location is a previously developed right-of-way (ROW) for existing pipelines. The location
of the existing pipelines is detailed in the Pipeline Layout figure, located in the Grading Application.
The proposed site will have a disturbance area of 0.16 acres within an existing ROW. The site is
located within the 7,732 acre parcel. An access road to the site location is maintained and owned by
OXY.
The propos Q ipeline will allow natural gas to be transferred from the Conn Creek 1 Compresso~ (CCl CS) to the 608-41 well pad. The CC4 pipeline will provide gas -lift to the
608-41 well pad to increase gas production and reduce the decline curve of natural gas well s on the
well pad. Pressure for transferring natural gas through the pipeline will be provided from the CCl
CS. Gas lift is a form of artificial lift used in wells that have insufficient reservoir pressure to
produce the well. The process involves compressing produced gas and injecting it through the
tubing-casing annulus. Injected gas aerates the fluid in the tubing to reduce its density whic h then
allows the formation pressure to lift the water column out of the well bore. Gas may be injected
continuously or intermittently, depending on the producing characteristics of Lhe well and the
arrangement of the gas-lift equipment. The amount of gas to be injected to maximize production
varies based on well conditions.
The CC4 Pipeline section is the only above-ground portion of the entire Gas-Lift pipeline servicing
the 608-41 well pad. Oxy has determined that locating the subject pipeline underground will
reduce possible damage from above-ground elements.
The CC4 Pipeline will be 0.16 acres and will transfer 1.2 million cfs/daily (gas volume). The
maximum capacity for the subject pipeline is 6 million cfs/daily (gas volume). The pipeline will be
buried at a depth of 5 feet a nd require a trench of 12 inches wide for placement. The pipeline is the
Flexpipe Linepipe (FPLP) model FP601. The FPLP is composed of a thermoplastic ja cket and liner
with structural la yers which allows the pipe to flex and bend. The FPLP are corrosive resistant
which will reduce the need to replace sections of pipeline compared to traditional steel pipeline.
The FPLP can be installed with a narrower trench, reducing ground disturbance. The maximum
operating temperature is 140°F with a pressure of 1,500 PSI. The outside diameter is 5.11 inches
and inside diameter is 3.90 inches. The FPLP weighs 4 .6 pounds per foot. The pipeline will have two
a bove-ground 4 " T valve configurations provide access to the pipeline for routine maintenance or
future connections into the High Pressure Gas Pipeline System. FPLP FP601 specifications are
detailed in the Flexpipe Details provided in the Gra ding Application. The construction phase will be
approximately 5-7 days for the site grading a nd installation of the CC4 Pipeline.
The existing pipeline ROW has established vegetation a nd permanent erosion control features are
not needed. During grading activities the following erosion co ntrols will be impl emented:
Minor Grading Permit Application Narrative
Garfield County Minor Grading Permit Application, 2014 Page 1 o
OXY USA WTP LP
Conn Creek 4-lnch Gas-Lift Replacement Pipeline
Spoil pile will be stored on the up-gradient side of the trench. The trench will serve as a
catchment basin for the spoil pile in the event that weather conditions cause erosio n in the
area of the site.
Silt fence or straw waddles will be installed on the down-gradient side of the entire trench
to ensure sediment is not transported off the ROW area
Trenching within the area of the creek crossing will be completed and backfilled within the
same day, significantly reducin g the amount of time for potential erosion and sediment
transport into the creek.
The subject pipeline will require a depth of cut less than 15 feet and the native slopes are less than
25%. Drainage patterns will not be altered in the existing ROW. The subject pipeline is not within a
floodplain and will not impact adjacent properties drainage. Drainage and erosion features are
detailed in the Site Plan and grading documents lo cated in the Grading Application. '
Facilities and Equipment Summary
The following section summarizes t h e structures and equipment that are currently existing and
proposed for the subject site.
Existing within ROW:
-Two Gas Gathering Pipelines
-Water Gathering Pipeline
-Water Distribution Pipeline
-Fiberglass Line
-Communication Line
Proposed:
-Conn Creek 4-lnch Gas -Lift Replacement Pipeline
-Two 4 -lnch T valve configurations
Purpose and Need
The CC4 pipeline will provide gas -lift to the 608-41 well pad to increase gas production and reduce
the decline c urv e of natural gas wells on the well pad. The proposed site is lo cated on OXY's
property and within the Cascade Creek field. CC4 Pipeline w ill increase production on existing wells
in the Cascade Creek field. The CC4 Pipeline s ite is critica l to OXY's ability to produce natu r a l gas in
Garfield County.
Location
The proposed CC4 Pipeline s ite plan is designed to be approximately 0.16 acres and will be
southerly located on parcel 2169-214-00-026, in the 29 and 32 Section s of Township 6 South,
Range 97 West of the 6th Principal Meridian, Garfield County. The subject parcel is approximately
7,732 acres. OXY USA WTP LP, the appli cant, is the owner of the property and the sole owner of
mineral rights for the subject parcel. The subject parcel is zoned resource lands-gentle s lopes . All
adjacent parcels are zoned reso u rce lands or public lands .

Noxious Weed Management Plan
for
Cascade Creek Operating Area
Mesa

OXY USA WTP LP
760 Horizon Drive, Suite 101
Grand Junction, Colorado 81506
Updated March 2013
Introduction
Noxious Weed Management Plan for
OXY USA WTP LP
Cascade Creek Operations
Garfield County, Colorado
OXY USA WTP LP ("Oxy") has developed this Noxious Weed Ma nagement Plan (Plan) to comply
with the Colorado Noxious Weed Act (C .R.S . Title 35, Article 5 .5) ("Act"), Colorado Oil and Gas
Conservation Act, local , and federal noxious weed management requirements, such as Garfield
County Planning Department and the Bureau of Land Management (SLM). The Plan also covers
specia l best management practices (BMP 's) for management of noxious weeds in two designated
State Natural Areas (SNA's) located on Oxy property .
The Act requires that "noxious weeds" be managed on private and public lands . The Act further
declares that control of noxious weeds sho uld use methods that are least damaging to the
environment but also practicab le and economica lly reasonable. The state requires management
of noxious weeds included on one of three lists (see Appendix A): List A -designated for
statewide eradication; List B -managed to prevent further spread and , for se lected species,
designated for eradication in large areas; and List C -of more localized concern, but for which
the state will provide education, research, and biological contro l assistance to jurisdictions that
choose to manage the species.
Oxy owns/leases and operates certain mineral properties in the Piceance basin , located in
Western Colorado. This Plan is intended to manage Oxy's oil and gas operational areas in order
to comply with all local , state and federal noxious weed management requirements including
Garfield County, Colorado Oil and Gas Conservation Commission (COGCC), and the BLM .
Compliance Statements
Oxy will manage all noxious weeds, as defined by the Act . the guidelines in the Garfield County
Noxious Weed Management Plan , the local BLM Pesticide Use Plan (PUP). any other approved
noxious weed management conditions of approva l (COA 's ) issued by a land management agency
in existing surface disturbed areas managed by Ox y as well as newly disturbed project areas.
Some noxious weed management COA's may be identified by a biological consu ltant at the time
of project specific inventories . The term , "disturbed area" includes all we ll pads. access roads,
easements, pipelines, and associated support facilities such as compressor stations, water
management facilities, and other areas disturbed by project activities . Disturbed areas also
include soil stockpi les, earthe n berms and other erosion control BMP's that require ground
disturbance for insta llation and maintenance. Oxy will co mply with COGCC noxious weed
management 1000 Series rules, which requires Oxy to keep all disturbed areas free of noxious
weeds .
Cascade Creek Noxious Weed Management Plan Page2
Weed Management Objectives and Implementation Strategies
The following are the overall objectives of the Plan:
• Inventory and monitor existing or new noxious weed infestation s using Global Positioning
System (GPS) equipment or other mapping techniques. In ventories shall occur at least
annually;
• Prevent new infestations of noxious weeds ;
• Utilize state certified contractors to implement an Integrated Weed Management (IWM)
protocol as recommended by the state or Garfield County Noxious Weed Management
plan to control or manage noxious weed populations ;
• Maintain a noxious weed inventory, herbicide application and mapping records;
• Restore disturbed areas to protect native plant ecosystems and watersheds from
degradation by noxious weeds.
Specific act ions to be taken to meet these objectives include :
• Bareground treatments will occur at existing facilities at the start of the spring season,
prior to noxious weed emergence to reduce the emergence potential of noxious weeds.
• Annual monitoring will occ ur at ex isting and new facilities, specifica lly looking for noxious
weeds. If noxious weeds are ide ntified, they will be mapped , treated, and the treatment
event will be logged .
• All treatment events will be logged by th e noxious weed treating contractor using a
Pesticide Application Record (PAR). See Appendix B for an example of what inform ation
should be collected; the contractor may choose their own format. The PAR will be use to
report noxious weed management activities to federal land managing agencies. In
addition to completing th e PAR, the noxious weed contractor will comp lete Oxy's noxious
weed tracking form , see Appendix C.
• Comp let ion of the PAR and Oxy's tracking form will serve as documentation of noxious
weed management activities .
• Where feasible implement area specific noxious weed management BMP's in the two
designated state management areas , see Appendix E.
Inventory and Monitoring
Before a new site is deve loped and when practical, Oxy will inventory th e site and adjacent areas
for noxious weeds, including access roads and other probable weed ingress route s. If
deve lopment activities are started in the winter months or when noxious weeds cannot be
identified, the new disturbance area will be inventorie d the next growing season . Noxious weed
locations (list A and List B species) will be collected with a GPS unit or mapped in relation to the
facility or landmark. Any noxious weed infestations found will be treated before site disturbance ,
if timing is approp ri ate. If the timing is not appropriate for noxious weed treatment , activities may
proceed and the weeds will be monitored and treated during the appropriate season. Weeds on
adjacent properties may be trea ted as appropriate with permission of the landowner. Populations
of Colorado or County List A and List B species (see Appendix A) will be reported to the County
Weed Manager. On federal lands or for federal projects , a Noxious Weed Inventory record w ill be

Plans for revegetation and reclamation of disturbed areas are site-specific , and will include a
plant list, method of seeding, how seeding success will be determined and how the revegetated
area will be monitored . Oxy will rely on existing surface use agreements , revegetation plan, or
Stormwater Management Plan, which has a recommended seed mix. BLM and FS seed mixes
are compiled on a site-specific basis, according to elevation and existing vegetation community
on the site. Non-native, non-persistent sterile grasses may be used to provide ground cover for
soil stabilization and weed suppression during temporary reclamation on both private and federal
land. See Appendix D for a sample Oxy Revegetation and Reclamation Plan .
Certified weed seed free straw, hay, mulch , seed or other materials will be used for soil
stabilization and/or revegetation purposes (Colorado Department of Agriculture certified inspector
to State standards). Seed tags will be available for inspection upon request of the Inspector.
Topsoil that is stock piled for more than one year will be seeded according to above standards at
the earliest practica l time to reduce the possibility of noxious weed establishment.
Revegetation efforts will be monitored annually until successful establishment of desirable or
intentionally planted seed or plants is confirmed . Noxious weeds found in revegetation will be
documented, and managed per guidelines in this Weed Management Plan .
Control and Management
The noxious weed contractor will follow the guidelines identified in the Nox ious Weed
Management Plan developed by the Colorado Department of Agriculture and the Garfield County
Noxious Weed Management Plan developed by the Garfield County Vegetation Management
department to identify, treat, and control noxious weeds. Treatments will include herbicide,
cultural , mechanical , revegetation , and biological control alone or i n combination as necessary for
efficient weed control. On federal lands, control and management methods (including herbicide
use) will be verified and approved with the appropriate land management agency representatives .
Noxious weed management activities on federal lands will comply with the BLM or other land
management agencies PUP. Annual reporting to the BLM or other land management agency will
be completed as prescribed in the PUP by the noxious weed contractor.
The accompanying treatment tables describe the management methods , rates, and timing of
control measures for specific targeted weeds (see Table 1 and Table 2). Treatment application
records will be retained by Oxy and available for inspection by agency personnel listed in ttie
contacts section below.
