Major Grading Permit Application Narrative
OXY USA WTP LP (OXY) is pursuing a Major Grading Permit for the Mesa 4 -Inch Water Gathering
Replacement Pipeline (M4WG Pipeline) in Garfield County. Approximately 5, 837 feet will be
replace and 11,690 square feet graded within an existing pipeline right-of-way (ROW). The
proposed site is located on private property, owned by OXY USA WTP LP, approximately 15 miles
north of DeBeque, Colorado. The pipeline will not require a land use change permit. The pipeline's
main function is to transfer produced water to and from OXY's facilities within the Cascade Creek
Field.
1.1 Description
The proposed project is to upgrade current fiberglass pipe with Flexpipe. All grading activities will
be conducted within a previously developed pipeline ROW. Replacement will occur in sections and
new pipe will be placed in the current alignment. The proposed site will have a disturbance area of
0.27 acres within an existing ROW. The site is located within the 7,732 acre parcel. An access road
to the site location is owned and maintained by OXY.
The proposed M4WG pipeline will allow produced water from well pads on the Mesa area to be
transferred to the valley for treatment at the OXY Central Water Handling Facility. After treatment,
the water is transported to the Mesa area for storage, reuse, or disposal.
The M4WG Pipeline will be 0.27 acres and will transfer 1000 bbl per day per well. The amount of
water to be transported varies based on well production. The pipeline will be buried at a depth of
4.5 feet and require a trench of 8 inches wide for placement. A surface disturbance of 2 feet ROW
was used for grading calculations. Every 1968 feet of pipe a coupling will be installed, requiring a 6 '
foot wide disturbance area.
7
The pipeline is the Flexpipe Linepipe (FPLP) model FP601. The FPLP is composed of a
thermoplastic jacket and liner with structural layers which allows the pipe to flex and bend. The �1 icy
FPLP are corrosion 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 above -ground 4" T -valve configurations which provides 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 Grading
Application. The construction phase will be approximately 15 days for the site grading and
installation of the M4WG Pipeline and one week for re -seeding.
The existing pipeline ROW has established vegetation and permanent erosion control features are
not needed. During grading activities the following erosion controls will be implemented:
- 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 erosion 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.
Major Grading Permit Application Narrative
Garfield County Major Grading Permit Application, 2015 Page 1 of 3
OXY USA W'rP LP
Mesa 4 -Inch Water Gathering Replacement Pipeline
- Trenching within the area of the creek crossing will be completed and backfilled within the
same day, significantly reducing 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 located in the Grading Application.
Facilities and Equipment Summary
The following section summarizes the structures and equipment that are currently existing and
proposed for the subject site.
Purpose and Need
The M4WG pipeline will provide transportation of produced water to and from the Mesa area of the
OXY's Cascade Creek Field. The proposed site is located an OXY's property and within the Cascade
Creek field. M4WG pipeline allows and supports facilities to efficiently reuse and treat produced
water. Replacing the current fiberglass pipe with Flexpipe will significantly increase pipe strength
and reduce risk of pipeline failure. The M4WG Pipeline site is critical to OXY's ability to produce
natural gas in Garfield County.
Location
The proposed M4WG Pipeline site plan is designed to be approximately 0.27 acres and will be
southerly located on parcel 2169-214-00-026, in Sections 4, 9 and 16 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 applicant, is the owner of the property and the sole owner of mineral
rights for the subject parcel. The subject parcel is zoned resource lands -plateau. All adjacent parcels
are zoned resource lands or public lands.

Oxy has proposed replacing sections of existing 4 -inch fiberglass pipeline with new 4 -inch
flexpipe, specifically, Pipe Sections 9.2, 15, 17, and 20 of the Mesa Water Gathering Pipeline
System. Revegetation activities are anticipated to take no longer than forty (40) days. Upon
completion of the installation, the pipeline trench will be backfilled, topsoil replaced on the entire
right-of-way and re -graded as closely as possible to pre -disturbance conditions. The entire
right-of-way will be reseeded by drilling the following seed mixtures:

To Soil Manaciment
Topsoil will be stockpiled so that it will not interfere with construction activities or cause potential
environmental problems. Should the construction phase of this project exceed forty (40) days,
appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding,
windbreaks, etc.).
Following final contouring, all backfilled surfaces will be covered evenly with the stockpiled
topsoil. The topsoil will be heavily pocked using the excavator bucket to form an uneven soil
surface complex which will aid in revegetation. Soil amendments or import of new topsoil is not
anticipated. Review of the vegetation establishment will be required to determine whether soil
amendments are required at a later date. (Attachment A).
Seedinq_Procedures and Schedules
As recommended by ERO Resources seeding shall be applied as soon as possible following
surface grading. The reseeding rate should be doubled for broadcast application. Oxy's
contractor will utilize surface roughing to create microclimates conducive to seed establishment
1
and growth. It is anticipated that the disturbed areas will be returned to match the original
vegetative state.
Seeding will be conducted by means of drilling the prescribed seed mix according to the
recommended rate. The seed will be drilled with a common range drill at a depth of 0.25 — 0.5
inch beneath the soil surface. The reseeding will be monitored and reseeded as appropriate
until the reclamation standards are acceptable to Garfield County Vegetation Management.
Disturbance area
The project has an anticipated total disturbance of approximately 4.0 acres (172,410 square
feet).

Drainage and Erosion Control Plan
The primary disturbance anticipated with the construction of this project is soil stockpile. Topsoil
will be stockpiled so that it will not interfere with construction activities or cause potential
environmental problems. Should the construction phase of this project exceed forty (40) days,
appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding,
windbreaks, etc.). The construction of the project is anticipated to return the grades to pre -
construction elevations as closely as possible. The construction plans prepared by D.R. Griffin
and Associates, Inc illustrate the anticipated grades.
Drainage
Nolte Associates prepared the Regional Drainage Analysis. The proposed pipeline route
associated with this project is located within the CON06 and CA03 drainage basins as
described within the Regional Drainage Analysis. This project is not anticipated to alter the
drainage patterns or flow rates described within the Regional Drainage Analysis. It is expected
that existing drainage measures will be maintained. Deviation from the Regional Drainage
Analysis is not expected, however, if site conditions dictate a deviation then a Colorado
Registered Professional Engineer shall be consulted. The Regional Drainage Analysis
prepared by Nolte Associates demonstrating drainage patterns for the project area is included
as Attachment B.
Erosion Control Measures
Olsson Associates prepared a Stormwater Management Plan for Cascade Creek Development.
It is anticipated that the project will be in conformance with the Stormwater Management Plan
(permit no. COR038414). The Stormwater Management Plan will be revised accordingly. An
exhibit demonstrating approximate locations of anticipated erosion control measures is included
as Attachment C.
The recommendations associated with the Reclamation Plan and review of the Drainage and
Erosion Control Plan were prepared on behalf of Olsson Associates under the supervision of:

Noxious Weed Management Plan for
OXY USA WTP LP
Cascade Creek Operations
Garfield County, Colorado
Introduction
OXY USA WTP LP ("Oxy") has developed this Noxious Weed Management 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 (BLM). The Plan also covers
special 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 should use methods that are least damaging to the
environment but also practicable and economically 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 selected 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 control 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 approval (COA's) issued by a land management agency
in existing surface disturbed areas managed by Oxy as well as newly disturbed project areas.
Some noxious weed management COAs may be identified by a biological consultant at the lime
of project specific inventones. The term, "disturbed area" includes all well 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 stockpiles, earthen berms and other erosion control BMP's that require ground
disturbance for installation and maintenance. Oxy will comply 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 Page 2
Oxy will report all State List A and List B noxious weed populations inventoried and treated and
any other species identified by Garfield County for eradication upon discovery to the appropriate
County designee
The Colorado Natural Areas Program (CHAP), which manages the designated SNA's have
provided Oxy with recommended noxious weed management BMP's that will aide in protecting
native plant species The recommended BMP°s will be applied where feasible.
Local Contacts
The local contact for Oxy's Plan include the Regulatory Advisor, who serves as Oxy's noxious
weed management coordinator and manages the noxious weed contractors.
• Regulatory Advisor — Daniel 1. Padilla, 970.263.3637
Garfield County's Vegetation Management contact number is 970.625.8601. Addition contact
information is listed in local contacts section of the Plan.
Operating Area
Oxy manages active and inactive leases associated with natural gas exploration in the fol:owing
areas of Garfield County.
• Cascade Creek Operating Area, which is separated into three primary fields:
Valley
▪ Mesa
▪ Logan Wash, this area contains two SNA's:
• Mount Callahan SNA
• Mount Callahan Saddle SNA
Oxy operates on split estate where surface lands may be wholly federal (BLM) and minerals
wholly fee owned and vice versa
Land Use Objectives
Oxy conducts natural gas exploration and production activities on fee and federal lease holdings
in Western Colorado. Land uses and types of facilities to be developed include access roads,
pipelines, well pads.. compressor stations, staging/storage areas for equipment and supplies, and
other associated natural gas development activities Some of the developments are short-term
temporary disturbances, such as staging areas and pipelines, while the access roads, well pads,
and other support facilities remain in active use for an estimated 20-30 years
Cascade Creek Noxious Weed Management Plan
Pogo 3
Weed Management Objectives and Implementation Strategies
The following are the overall objectives of the Plan:
• Inventory and monitor existing or new noxious weed infestations using Global Positioning
System (GPS) equipment or other mapping techniques. Inventories 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 actions 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 occur at existing and new facilities, specifically looking for noxious
weeds. If noxious weeds are identified, they will be mapped, treated, and the treatment
event will be logged.
• All treatment events will be logged by the noxious weed treating contractor using a
Pesticide Application Record (PAR). See Appendix B for an example of what information
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 the PAR, the noxious weed contractor will complete Oxy's noxious
weed tracking form, see Appendix C.
• Completion 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 developed and when practical, Oxy will inventory the site and adjacent areas
for noxious weeds, including access roads and other probable weed ingress routes. If
development activities are started in the winter months or when noxious weeds cannot be
identified, the new disturbance area will be inventoried 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 appropriate. If the t.ming is not appropriate for nox,ous weed treatment, activities may
proceed and the weeds will be monitored and treated dunng the appropriate season Weeds on
adjacent properties may be treated 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 will be
Cascade Creek Noxious Weed Management Plan Page 4
completed each time a List A or B weed infestation is inventoried (with the exception of redstem
filaree and quackgrass), and the populations will be reported.
Monitoring will be conducted at least annually, early in the growing season, by Oxy staff or
contractors, and in coordination with BLM staff on federal lands. For most of Oxy's operation
areas, monitoring will occur between May and July. All previously treated noxious weed sites will
be monitored for regrowth and scheduled for re -treatment as necessary. All disturbed areas
under Oxy management will also be monitored to ensure there are no new weed infestations.
Prevention
The purpose of prevention measures is to preclude the introduction of new or existing noxious
weeds from the project area to un -infested areas or from adjacent land into the project area.
Construction Prevention Measures
Construction equipment entering project areas (backhoes, trackhoes, dozers, blades,
rollers, lowboys, equipment trailers, etc.) will be power washed or otherwise cleaned.
"Equipment" is defined as any earth moving and any other machinery, trucks or vehicles,
trailers and tools. On Federal property, equipment may be inspected by BLM or Forest
Service (FS) personnel. Pickup trucks, SUVs, vans, water trucks, and pipe trucks should
also be clean but do not require inspection prior to entering federal lands. Where
required, track pads, gravel beds or rumble strips will be installed at ingress/egress points
to the site to limit weed seed from entering or leaving the site.
Soils from infested areas of the project site will not be moved off site, but will be
stockpiled and treated for weeds as necessary. If infested soils are moved off site, they
will be kept on Oxy -managed property, monitored, and treated as necessary. Stockpiled
soils will be monitored and treated to control noxious weeds. All purchased products
used in development and reclamation of a site will be inspected or certified as weed -free
whenever possible, including soils, rock and gravel. seeds, mulch and erosion control
products.
Operational Prevention Measures
Existing facilities such as well pads, valve/meter sites, and compressor stations that
require work areas to be free of vegetation shall have bareground treatments at the start
of spring. Existing facilities such as access roads and reclaimed pipeline right-of-ways
shall be monitored through the growing season for noxious weeds and noxious weeds
identified will be treated.
Revegetation
The goal of reclamation and revegetation of a site after disturbance is timely establishment of a
desirable native plant community and prevention of noxious weed infestation. Elements of
successful revegetation include the use of topsoil that was set aside during construction and kept
weed -free, reseeding with appropriate species to establish plant cover, and stabilization of the
soil surface with the appropriate mulches, lackifiers, and erosion control products as needed.

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 practical 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 Noxious 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 in 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 the
contacts section below.

Sample Revegetation and Reclamation Plan
The proposed facility will be in operation for an anticipated period of approximately
during development and production of Oxy's natural gas production operations. Upon termination
of the development and production activities, the facility will be reclaimed, as outlined below.
• All equipment and structures will be removed.
• OXY will remove all safety and storm water BMPs, and other surface objects from the
premises.
• OXY 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).
• OXY will monitor the site to ensure that 70 percent of the pre-existing vegetation is
achieved, per the requirements of the area wide CDPHE Stormwater Permit for Cascade
Creek and Collbran Developments.
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 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 attached seed mixtures.
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
Cascade Creek Noxious Weed Management Pian Page 19
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:
• No -till -drill (no soil preparation required);
• 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 Tess 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.
