RE: NPR O04 Gathering Pipelines
Purpose:
The purpose of this letter is to present the calculated design pressures for the NPR O04
Gathering Pipelines.
Background:
Caerus Oil and Gas, LLC owns and operates natural gas facilities within the Piceance
Basin of Garfield County. Garfield County Development has requested certification of the
design pressures for new natural gas pipelines. This certification must be done by a
Professional Engineer registered within the state of Colorado.
ASME Design Pressure Formula:
The American Society of Mechanical Engineers Code for Pressure Piping (ASME 831-8-
2018) was used for calculating the design pressure, which is the calculated allowable
design pressure of the system. Section 841 Steel Pipe has a steel pipe design pressure
formula (Section 841. 1 . 1 ).
P = 2St FET
D
Where:
P = design pressure (psi)
g = pipe yield strength (psi)
1= pipe wall thickness (in)
¡ = pipe outside diameter (in)
F = design factor
E = longitudinaljoint factor
T = temperature derating factor
The input variables for each pipeline and the associated calculations were provided by
Caerus and are detailed on the attached spreadsheet.

2019.10.04.docx Page I of 2
Results:
Two pipe segments were analyzed using the design pressure formula from ASME 831-
8-2018 and the results are in Table 1 below.
Table 1 Theoretical Maximum Allowable Pressure

4,382
Conclusions:
River City Consultants, lnc. agrees with Caerus's choice of design variables and the
specified pipe materials for each line/application. The actual operating pressure of these
Caerus systems will be well below the calculated allowable design pressure. Further,
each of these pipelines will be hydrotested as part of Caerus's pipeline construction
quality assurance program.
Please let me know if you have further questions,

I.O INTRODUCTION
1.1 Project Description
At the request of Caerus Oil and Gas, LLC (Caerus), WestWater Engineering (WestWater) has prepared
this Noxious Weed Management, Vegetation and Reclamation Plan for the proposed O04 696 Pipeline
project that would be located on privately owned lands in Garfield County, Colorado in Section 4,
Township 6 South, Range 96 West (Figure l). This document reports the results and analysis of the
findings that are pertinent to Section 9-102-M of the Garfield County Land Use and Development Code
(as amended) as it applies to this project.
This Vegetation and Reclamation Plan applies to the areas where Caerus plans to cause surface
disturbance associated with the proposed pipeline installation. The current land uses include rangeland,
wildlife habitat, and oil and gas development.
1.2 General Survey Information
Pedestrian surveys of the project area were conducted by WestWater biologists on December ll,2019
within 30 meters of the pipeline centerline (Figure l). Surveys were conducted outside the annual
growing season for noxious weeds; however, plants were still able to be identified based on vegetative
structure that remained from the previous growing season. Identification of plant species was aided by
using pertinent published field guides (Ackerheld 2015, Brown 1976, Kershaw et al. 1998, Whitson et al.
2001, CWM A2007, Weber and Wittmann 2012). Noxious weed locations were recorded with the aid of
handheld global positioning system (GPS) receivers usingNADS3 map datum, with all coordinate
locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12. Mapped soil
types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of
Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics at the
project site (NRCS 2019).
2.0 Landscape Setting
2.1 Terrain
The proposed pipeline reroute would be located along foothills of the Roan Plateau at an elevation of
approximately 5,800 feet. The area surrounding the project is composed of steep sided ridges rising
rapidly to the Roan Plateau.
2.2Yegetation
The proposed pipeline would be located within existing disturbance associated with an access road to an
existing well pad and an existing pipeline corridor. Vegetation along the proposed pipeline route consists
of re-seeded native and non-native grasses, shrubs, and forbs. Common species observed along the
proposed pipeline route are described in Table l.

3.0 NOXIOUS WEEDS
3.1 Introduction to Noxious Weeds
Most noxious weed species in Colorado were introduced, mostly from Eurasiao either unintentionally or
as omamentals that established wild populations. These plants compete aggressively with native
vegetation and tend to spread quickly because the environmental factors that normally control them are
absent. Disturbed soils, altered native vegetation communities, and areas with increased soil moisfure
often create prime conditions for weed infestations. The primary vectors that spread noxious weeds
include humanso animals, water, and wind.
The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop
noxious weed management plans. Both the State of Colorado and Garfield County maintain a list of
plants that are considered to be noxious weeds (Garfield County 2019). The State of Colorado noxious
weed list segregates noxious weed species based by priority for control:
WestV/ater Engineering Page 2 of 12 December 2019
L List A species must be eradicated whenever detected.
2. List B species spread should be halted; may be desigrated for eradication in some counties.
3. List C species are widespread and the State will assist local jurisdictions which choose to manage
those weeds.
The Garfield County V/eed Advisory Board has compiled a list of 40 plants considered to be noxious
weeds within the county (Appendix A). The Garfield County Weed Advisory Board has duties to:
1. Develop a noxious weed list;
2. Develop a weed management plan for designated noxious weeds; and,
3. Recommend to the Board of County Commissioners that identified landowners submit an
integrated weed management plan for their properties (Garfield County 2016).
3.2 Observations
Weed species listed by the State of Colorado (2005) detected in the project area included cheatgrass
(Bromus tectorum),common mullein (Verbascum thapsus), plumeless thistle (Carduus acanthoides),and
musk thistle (Carduus nutans). Weeds were thinly scattered along areas of previous disturbance (Figure
2). No dense infestations of noxious weeds were observed during the survey.
In areas where soil disturbances have created growing conditions that favor non-native vegetation, several
unlisted nuisance weed species are present. These plants can impact revegetation efforts and cause
financial losses due to decreased seeding success and associated costs ofreplanting. The presence of
these plants creates increased competition for resources and can negatively affect desirable native plant
species. Plants in this category observed or known to exist in the project area include Russian thistle
(Salsolø tragus) and tall tumble mustard (Sisymbrium altissimum).
3.3 Integrated Weed Management
Control of invasive species is a diffrcult task and requires intensive on-going control measures. Care
must be taken to avoid negatively impacting desirable plant communities and inviting infestation by other
pioneer invaders. Weed management is best achieved by employing varied methods over several growing
i"asons, including inventory (surveys), direct teatments, prevention through best management practices,
monitoring of treatment efficacy, and subsequent detection efforts. Weed management is often limited to
controlling existing infestations and prevention of further infestations, rather than eradication, but through
effective weed management practices eradication can be possible in small to medium sized weed
populations.
Assessment of the existence and extent of noxious weeds in an area is essential for the development of an
integrated weed management plan. This report provides an initial assessment of the occurrence of
noxious weeds for the project area. In order to continue effective management of noxious weeds, further
inventory and analysis will be necessary to 1) determine the effectiveness of the past treatment strategies;
2) modifu the treatment plan, if necessary; and 3) detect new infestations early, which would result in
more economical and effective treatments.
3.4 Prevention of Noxious Weed Infestations
tweed management can be costly, and heavy infestations may exceed the economic threshold for practical
treatment. Prevention is an especially valuable and economical strategy for noxious weed management.
Several simple practices should be employed to prevent weed infestations. The following practices will
prevent infestation and thereþ reduce costs associated with noxious weed control:
o Prior to delivery to the site, all equipment and vehicles, including maintenance vehicles, should
be thoroughly cleaned of soils from previous sites which may be contaminated with noxious weed
seeds.
'WestWater Engineering Page 3 of 12 December 2019
o If working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially
seed-bearing soils and vegetative debris at the infested area prior to moving to uncontaminated
terrain.
o Avoid driving vehicles through areas where weed infestations exist.
o Use of weed-seed-free reclamation materials such as mulch and seed.
3.5 Treatment and Control of Noxious Weed Infestations
The treatment method and timing will be determined by the project proponent and their contracted
licensed pesticide applicators. The recommendations provided in this report will be considered when
developing annual treatment plans. General control methods for the species detected in the project area
are provided for reference in Table 2.
Table 2. General noxious weed control methods for in the
Bold : Ga¡field County List
3.6 Recommended Treatment Strategies
The following treatment strategies are presented for reference. It is important to know whether the weed
species being managed is an annualo biennial, or perennial to select strategies that effectively contol and
eliminate the target. Treatment strategies vary depending on plant type, which are summarized in Table
3. Herbicides should not always be the first treatment of choice when other methods can be effectively
employed.

1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If
flowers or seeds develop, cut and bag seed heads.
2. Cut roots with a spade 2"-3" below soil level.
3. Treat with herbicide in seedling, rosette or bolting stage, before flowering.
4. Mow biennials after bolting stage but before seed set. Mowing annuals will not prevent flowering
but can reduce total seed production.
'WestWater Engineering Page 4 of 12 December 2019
Some weeds, particularly annuals and biennialso can develop resistance to herbicides. The ability to
quickly develop immunity to herbicides, especially when they are used incorrectl¡ makes it imperative to
use the proper chemicals at the correct time in the specified concentration according to the product label.
Excessive application, either in frequency or concentration, can result in top kill without significantly
affecting the root system. Repeated excessive applications may result in resistant phenotypes.
3.7 NoxÍous Weed Management - Best Management Practices
Construction: The following practices should be adopted for any construction project to reduce the costs
of noxious weed control and aid in prevention efiforts. The practices include:
o Prior to delivery to the site, equipment should be cleaned of soils remaining from previous
construction sites which may be contaminated with noxious weeds.
o Equipment and material handling should be done on established sites to reduce the area and
extent of soil compaction.
o In all cases, temporary disturbance should be kept to a minimum.
. Top soil, where present, should be segregated from deeper soils and replaced as top soil on the
final grade, a process known as live topsoil handling.
o If stored longer than one growing season, topsoil stockpiles should be seeded with non-invasive
sterile hybrid grasses.
o If working in weed infested sites, equipment should be cleaned of potentially seed-bearing soils
and vegetative debris prior to moving to uncontaminated terrain.
o After construction, disturbed areas outside the fooþrint of the development should be
immediately reseeded with an appropriate seed mix.
Herbicides: Many of the listed noxious weed species in Colorado can be controlled with commercially
available herbicides. Annual and biennial weeds are best controlled at the pre-bud stage after germination
or in the spring of the second year. Selective herbicides are recommended to minimize damage to
desirable grass species.
It is important that applicators adhere to concentrations specified on herbicide containers. Herbicides
generally do not work better at higher concentrations. Herbicide failures are frequently related to high
concentrations that result in top kill before the active ingredient can be transported to the roots tluough
the nutrient translocation process. If directed on the herbicide label, a surfactant or other adjuvant should
be added to the tank.
Grazing: In the event grazing is allowed in the projectare4 it should be deferred in reclaimed areas until
revegetation ofdesirable species has been successfully established and seeded plants have had
opportunity to reproduce.
Monitoring: Areas where noxious weed infestations are identified and treated should be inspected over
time to ensure that control methods are working to reduce and suppress the identified infestation. The
sites should be monitored until the infestations are eliminated. These inspections can then be used to
prioritize future weed control efforts.
3.8 Commercial Applicator Recommendations
A certified commercial pesticide applicator licensed in rangeland andlor right-of-way/industrial weed
control (depending on site characteristics) is a necessary choice for herbicide control efforts. An
applicator has the full range of knowledge, skills, equipment, and experience desired when dealing with
tough noxious weeds. ln addition, the purchase and use of restricted use herbicides requires a Colorado
pesticide applicator license.
V/estWater Engineering Page 5 of 12 December 2019
4.0 REVEGETATION - RDCLAMATION
Successful reclamation ofthe projectarea is dependent upon soil type and texture, slope gradient and
aspect, proper weed control, available water, and revegetation with suiøble plant species. Site-specific
reclamation plans utilizing native species should be developed with a qualified reclamation contractor.
Reclamation services using multiple seed bin range drills and specialized equipment are available and
should be used for reclamation seeding projects.
Soil Preparation
Compaction can reduce water infiltration and also hinder the penetration of the sprouting seed. Practices
that will reduce compaction and prepare the seedbed include: scarification, tillage, or harrowing
(Colorado Natural Areas Program et al. 1998).
ln areas with slope greater than three percent or where laminar flows from runoff could affect reseeding
success, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or
furrows perpendicular to the direction of slope. When utilizing hydro-seeding followed by 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 should be done as part of the hanowing. Furrowing can be
done by several methods, the simplest 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.
Soil Ämendments
The addition of soil amendments in rangeland reclamation projects can create more optimal growing
conditions for non-native or invasive plant species, with which native plants compete poorly. There is
potential that the use of soil amendments (fertilizer) containing nitrogen will disproportionately benefit
undesirable annual plants (Perry et al. 2010). If the company determines the use of soil amendments to be
beneficial, the type and rate should be based on results from lab analysis of soil samples collected at the
site.
A potentially beneficial alternative method to enhance reclamation success, particularly where there is
poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi (AMF). These
fungi, mostly of the genus Glomus, are symbiotic with about 80 percent of all vegetation. Endo-
mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful in reclamation. In
symbiosis, the fungi can increase water and nutrient transfer capacity of the host root system (Barrow and
McCaslin 1995). Over-the-counter commercial products are available, and the best products should
contain more than one fungus species.
Compacted soils respond well to fossilized humic substances and by-products called humates. These
humates, including humic and fulvic acids and humin were formed from pre-historic plant and animal
deposits and can benefit reclamation efforts on compacted soils when applied as directed.
Seed Mixture
The recommended seed mix (Table 4) is adapted from the Bureau of Land Management's Colorado River
Valley Field Office seed menu recommendations (BLM 2013). This seed mix is well suited for pinyon
juniper woodlands, mountain sagebrush and Wyoming sagebrush shrublands common along the foothills
of the Roan Plateau. The mix includes perennial native grasses and forbs that should establish well,
protect topsoil, and provide a basis for rehabilitation of the site upon reclamation. Since the project area
is privately owned, the landowners may request a different seed mixture.

*Based on 60 pure live seeds (PLS) per square foot, drill-seeded. Double this rute (120 PLS per square
foot) ifbroadcast or hydroseeded.
For best results and success, reseeding should be done in late autumn. The seed application rate should be
doubled for broadcast applications such as hydroseeding or hand broadcasting of seed (CI.llf 1998).
Seeding Methods
The preferred seeding method would be with a multiple seed bin range drill with no soil preparation other
than simple grading to slope and imprinting and water bars where applicable. This method would likely
also be the most economical method. Hydroseeding or hand-broadcast seeding at twice the recommended
drill seed rate is recommended for steep slopes or for smaller areas where drill seeding would be
impractical or dangerous.
Alternative seeding methods include, but are not limited to:
o harrow with just enough soil moisture to create a rough surface, broadcast seed and re-harrow,
preferably at a 90-degree angle to the frst harrow;
. hydroseeding; 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. Howevero these methods have been observed to be
effective in similar landscapes. After desired grasses are established and control of target weed species is
successful, then shrubs, forbs, and trees can be planted without concern for herbicide damage. Few native
forb seeds are available commercially as cultivars. Most are collected from natural populations. Native
shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past
experience has shown that stabilizing the soil with grasses, accomplishing weed control, and then coming
back to plant live, containerized woody species in copses has been the most cost-effective method for
establishing the woody species component of the plant community.
For sites where soil disturbance will be temporary, grasses should be drilled after construction activities
cease and the equipment is removed from the site. After two years of controlling weeds (with herbicides)
and allowing the grasses to become established, forbs and woody species should be inter-seeded or hand-
planted to increase the diversity and value of the reclamation plantings.

Mulching
Crimped straw mulch would be the most cost effective and practical method of mulching areas prone to
erosion after drill seeding this site. No mulching is recommended for areas that are hydroseeded. Potential
detrimental effects of mulching include the introduction of weed species and the establishment of non-
native cereal grains. Use of a certified weed-free sterile wheat hybrid straw mulch would limit these
effects.
BMPs
Excelsior wattles or straw bales at the toe of steep slopes and water discharge points are appropriate to
help control water velocity flowing offthe alignment during storms and spring runoff. Terracing slopes
near or exceeding 3: I will reduce erosion, benefitting topsoil and seed retention and thereby improving
revegetation success.
