USR QUESTIONNAIRE
Planning Questions
1. Explain, in detail, the proposed use of the property:
The proposed use of this Right -of -Way is a loin natural gas pipeline.
This gas pipeline is approximately 6 miles long and will flow from the tie-in site approximately 1/2 mile east of the
Highway 52 and WCR 41 intersection to the Fort Lupton Gas Plant approximately 1 mile south of the WCR 12
and WCR 35 intersection.
2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the
Comprehensive Plan:
Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of
the economy of the County." The proposed 20in n natural gas pipeline will contribute to the expansion of t h e
county's industrial economic base by transporting valuable resources and contributing to the increased capacity
for future marketing of natural gas production in Weld County. In addition, the pipeline is below grade and,
therefore, will not affect anything above grade after construction.
Section 22-2-80(C) states that `The land use applicant should demonstrate that the roadway facilities associated
with the proposed industrial development are adequate in width, classification, and structural capacity to serve
the development proposal," The new development proposal will not affect traffic in such a way as to conflict
with current transportation infrastructure, as the pipeline will be built within a Right -of -Way and any roads will
be bored under, rather than trenched across. The pipeline will comply with all federal, state, and local policies
and legislation per Section 22-2-80(E).
Section 22-2-90(C) states that, due to the over capacity of pipelines and refineries in the state, there is an
increase in need for transportation and storage, The most efficient and safe way to transport natural gas is by
pipeline because it negates the need for the transportation of this resource by truck. This benefits the county by
allowing for less impact on county roads, minimal impact on land, better air quality, and the economic
advantages that pipeline infrastructure brings.
3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the
zone district in which it is located:
Section 23-3-40 indicates that oil and gas support, service, and pipelines are acceptable as a Use by Special
Review within the district.
4. Describe what type of lard uses surround the site. Explain how the proposed use is consistent and compatible
with surrounding land uses.
The surrounding land usage for the site in question is primarily agriculture. The new pipeline will be routed
within new rights -of -way and will not interfere with agricultural production. The pipeline will be compliant with
49 CFR 192.

Discovery Emergency Response Plan (DERP)
Section 2 — Incident Reporting and Management
Purpose of Plan
The purpose of this Discovery emergency response plan is to establish procedures and
responsibilities to all foreseeable emergencies that may occur at Discovery Midstream DJ
assets. An emergency is defined as any situation presenting a threat to human life, physical
well-being, and company or personal property.
The main objectives in any emergency response will be as follows (listed by order of
importance) :
• Protection of personnel and the public
• Protection of the environment
• Compliance with federal, state, and local laws and regulations
• Adhering to safety protocols
Restore normal operating conditions
Discovery Midstream works to prevent emergency situations from occurring by implementing
and adhering to a culture which values safety and by meeting and exceeding industry best safety
practices. Examples include:
• Use of all —steel pipe manufactured in the USA for Discovery oil and gas lines
• Pipelines buried further underground than standard three (3) feet
• Use of thicker, stronger, higher grade pipe than required by standard best practice
• Adherence to strict welding standards and 100% X -Ray of all welds
• Integration of a rigorous pipeline integrity management program
This plan is supported by the Discovery Midstream Leadership team. The plan furnishes
adequate emergency protection and provides training for the employees, contractors, and visitors
at the facility.
This plan applies to all employees, contract employees, guests and visitors to the facility during
normal office hours, unless otherwise noted below:
• Employees working outside normal hours will be responsible for carrying out the
appropriate actions of this plan.
Pre -Planning
During pre -planning it is important to remember that no two emergency incidents are alike. Look
at all the possibilities surrounding the emergency. This includes the size of the event,
community and environmental impact, and the possibility of several types of emergencies which
could occur at the same time.

DJ Asset Information
Emergency Planning & Response
The Fort Lupton Gas Plant, compressor stations and gathering system have various interlocks,
relief valves, and alarms which function to alert personnel and/or protect equipment against
process conditions exceeding design parameters. Many of these process safeguards are critical
equipment subject to regular testing and preventative maintenance as defined in facility
mechanical integrity program. The safeguards prevent emergency conditions from occurring.
The Discovery Midstream Gas Plant and compressor stations also have equipment and systems
available for personnel to actively respond to an emergency condition. These include:
Facility Emergency Shutdown System (ED)
Portable Fire Extinguishers placed at required intervals
• Fixed Gas Detectors with equipment shutdown capabilities
• First Aid Station
• Portable Gas Detectors
• Smoke Detectors in occupied buildings

Incident Levels
Discovery Midstream incorporates three incident levels as part of the "Incident Notification
Proce ure, " (ref. Document 2.1, Incident Notification) The Incident Notification Procedure
assures an incident is promptly addressed at appropriate level to provide resources and support to
control and mitigate incident. Implementation of a three tier system helps ensure notification of
State and Federal agencies (as applicable), while enabling Discovery Midstream to evaluate
impact of incident on employees, general public, and customers.
In order to properly respond to any emergency, incidents should be classified into one of three
levels. The incident level is determined by complexity of the incident, risks to company
personnel and public, and impact on the environment. The three level classifications will be
used and communicated to all personnel within the company.
Level I Incident
The most serious and highest level incident. Level 1 incidents are usually on going and typically
involve at least one of the following:
a. Any fatality
b. Event requires support of government or Emergency Responder agencies
c. A non -incipient fire, rupture or explosion involving a Discovery Facility that requires
assistance from Emergency Responders
d. Any media attention at a Discovery Incident
e. Results in more than $100,000 in estimated Property damage
*A Level 1 Incident will automatically activate the Corporate Emergency Support Team and
Emergency Operations Center.
Notification Protocol:
a. Immediately notify local Supervision, Discovery Operations Center (DOC), Director of
Operations, COO
b. Discovery Operations Center (DOC) will activate Discovery local First Responders) and
local city/county fire/emergency organization if needed.
c. Discovery Operations Center (DOC) will telephone local city/county officials,
landowners and/or local citizens if off -site impact.
d. Discovery Operations Center (DOC) will communicate (text, email or phone call) all
Corporate Personnel as appropriate.

Section 2 -- Incident Reporting and
Management
Incident Command System
Discovery Midstream follows an Incident Command System (ICS) structure when responding to
any incident. While most incidents are small enough that only limited incident command will be
required, larger incidents may require a full-scale ICS. The ICS is designed to enable effective
and efficientincident management by:
• Integrating a combination of facilities, equipment, personnel, etc. within a common
organizational structure
• Enabling response measures to be scaled according to nature and size of incident
• Involving only those functions required for level of response (i.e. operations, finance,
public relations)
• Allowing one person to take charge of incident for the company and determine size of
response required
• Merging into and working with ICS of responding agencies (most governmental agencies
use an ICS)
Discovery ICS matrices for Level 1, Level 2, and Level 3 incidents are provided. The formats are
for full-scale ICS, while normally only a portion of the ICS will be required. For Level 1 and
Level 2 incidents, personnel will assume responsibility for primary duties in ICS. One person
may assume various or all responsibilities for Level 3 incidents. The ICS structure is meant to be
flexible. The Incident Commander is responsible for establishing the size and strength of the
team. Primary jobs are:
• Incident. Commander
Director of Operations (Incident Response Leader)
• Operations Lead (Logistics — Calls contractors and field assistance)
• Manager of Engineering (Planning — Decides on response strategies/schedules events)
• Chief Operating Officer (Executive Lead)
• Finance Office (Receives invoices, approves and signs)
Media Relations Officer (Interacts with media, community, etc.
*Note — First on -scene employee is the incident commander until other employees or agency
responders arrive with increased training and experience in handling type of incident.

General Actions
The first person at the scene of an emergency may be faced with a complex situation. A "First
Responder" should try to remain calm, exercise decisiveness, and provide assurance. A First
Responder should take the following steps and improvise as needed:
1, Scan surroundings to ensure own safety and safety of those who may enter area. A
general assessment of situationwill help clarify actions required. If person(s) with
injuries are present, contact appropriate emergency services (if necessary) and if
comfortable, voluntarily treat injured person(s) to best of your training and abilities.
2. Evacuate people in immediate danger or with injuries if comfortable and if movement
will not cause further harm. If willing, administer first aid, if necessary, per training.
Arrange for traffic control as required. Be firm, explicit, and courteous with the public.
Exert positive leadership and give instructions calmly.
3. Isolate and eliminate any sources of ignition, such as running engines, sources of
sparks, etc. Check road crossings, public utilities, and overhead power lines for danger
from possible fire. Shut down operations as needed.
4. Open or close valves as necessary, if it can be done safely, to eliminate the flow of gas
to the affected area.
5. Contact your supervisor and Discovery Midstream Operations Center and give a brief
overview of the incident and your actions. Based on Level of incident will determine
emergency response plan going forward.
6. Maintain scene control until relieved by a supervisor or more experienced person.

Location:
secured, the leak shall be stopped by suitable means (i.e1, Shut down compressors
or isolate the leak through the use of block valves).
F Initial Response for an Unexplained Gas Loss:
a. The initial response shall be to dispatch an operations employee to the site
suspected to search the area for the source of the leaking gas.
b. If there is difficulty locating a suspected leak, the following steps shall be
implemented:
i. Shut down the line in question under pressure and watch for a pressure
drop. Close intermediate valves to isolate leaking section.
ii. Look for signs of damage to vegetation, wilted leaves, etc.
iii. Use a probe bar to make holes above the line, taking care not to hit the line
itself, and sniff the holes with a leak detector.
iv. Using detection equipment, inspect the open end of casing vents.
v. Obtain more sensitive equipment to perform a flame -ionization survey.
vi. If required, shut down and isolate the line into sections and determine
which section is not holding pressure. See the Discover Pipeline tactical
Plan for valve locations.
3. Action to be taken
a. Determine if a 911 call is needed. If the leak is in the pipe itself, and is escaping
from a small hole or pit, the leak may be stopped with a repair clamp.
b. After this temporary repair has been made, the line should be permanently
repaired when conditions are safe to do so. If corrosion is suspected, a survey of
the immediate area should be made to check the effectiveness of the cathodic
protection in the area.
c. If the leak is too large for a temporary repair, the system should be shut down,
isolated from the stations, and the nearest isolation valves closed. The affected
segment of line should then be blown down to atmospheric pressure and repairs
made by qualified and approved personnel.
4. Returning to Service
a. The amount of time required for purging will depend on the pressure used to
purge, the location of the repair along the line, and the amount of air allowed into
the line during the repair procedure. As each incident may contain unique
elements, a plan for returning to service will be prepared for each incident, in
accordance with the Purging Procedures in the Discovery Midstream Pipeline
System Operations and Maintenance Manual (reference Gas O&M 1501).
b. After the line is back in operation, a thorough investigation of the cause of the
leak shall be made and action taken to prevent a re -occurrence. This may entail
sending a specimen of the pipe from the leak site to an independent laboratory for
examination, if the leak was due to failure of the pipe, a weld failure, or corrosion.
If the leak was caused by third party damage, analysis may not be necessary.
5. The Pipeline Operator, employee team member, or authorized designee shall:
a. Monitor line pressure at delivery and receipt points and station sites.
b. Open or close isolation valves as necessary to stop the supply of gas to the affected
area.

1.0 INTRODUCTION
Discovery Di Services, LLC, requested that SWCA Environmental Consultants (SWCA)
complete a delineation of potential waters of the 1.1,S., commonly referred to as "wetland
delineation," and an evaluation of the potential presence of federally listed species for the West
Milton pipeline located in Weld County, Colorado. SWCA conducted the wetland delineation
and species evaluation within a 200 -foot -wide survey corridor around the proposed centerline.
The wetland delineation includes the identification and recording of physical features that may
be considered waters of the U.S. as defined by the U.S. army Corps of Engineers (USACE).
Waters of the U.S. include most rivers, creeks, streams, lakes, and their associated special
aquatic sites. Special aquatic sites include sanctuaries, refuges, wetlands, mud flats, vegetated
shallows, coral reefs, and riffle and pool complexes. When applying for a Clean Water Act
permit, the USACE requires special aquatic sites to be addressed separately from other waters
of the US., if they are present.
Wetlands are the most common special aquatic site and are defined by the USACE as "areas
that are inundated or saturated by surface or groundwater at a frequency and duration sufficient
to support, and under normal circumstances do support, a prevalence of vegetation typically
adapted for life in saturated soil conditions" (USAGE 1987). For an area to be considered a
wetland, it must support the following under normal circumstances: 1) the presence of
hydrology showing regular inundation; 2) a predominance of hydrophytic (adapted to moist or
saturated soils) vegetation; and 3) soils characteristic of frequent saturation (i.e., hydric soils)
(USACE 1987, 2010).
2.0 PROJECT DESCRIPTION
The West Milton pipeline is approximately 5.0 miles in length, with the west terminus located
4.2 miles east of Fort Lupton and the east terminus located 1.4 miles west of Hudson, Colorado
(see Figure 1 in Appendix A). The land use along the pipeline is predominantly agriculture and
pasture. The project also crosses herbaceous native upland grassland generally in poor condition
due to anthropogenic disturbances.
Pipeline trenching activities will be completed using standard construction practices. The trench
will be positioned to one side of the construction right-sof-way (ROW) to allow for spoil to be
placed opposite of the wider working side. The 80 -foot -wide construction ROW is composed
of a 0 -foot -wide permanent easement and a 30 -foot -wide temporary construction easement.
All water features will be bored, thereby avoiding any impacts to waters of the U.S. No
permanent loss of wetlands or waters will occur as a result of constructing the pipeline.
3.0 METHODS
The methods described herein were implemented in the pre -fieldwork desktop review and field
surveys, and in the reporting of the results and production of all maps and information contained
in Section 4.0 and Appendix A, respectively.

Weld 'out', Colorado
3.1 PRE -FIELD Lam.'
Prior to field surveys, SWCA performed a desktop analysis to review baseline data for
biological resources in the project area, including U.S. Geological Survey (TUGS) topographic
quadrangles, National Wetlands Inventory (NWI) data, USGUSGS National Hydrography Dataset
(NHD), Colorado Parks and Wildlife/Colorado Oil and Gas Conservation Commission wildlife
maps, and recent aerial imagery provided on Google Earth. SWCA also conducted a desktop
review for federally listed species and their critical habitats, if designated, in the project area.
3.2 FIELD SURVEY
An SWCA biologist conducted the field surveys in September 2017. The biologist performed
a pedestrian survey of a 200 -foot -wide corridor centered on the proposed pipeline. This survey
corridor, wider than the 80 -foot construction ROW, will allow slight adjustments to the
centerline without necessitating new surveys. Nevertheless, adjustments to the centerline
alignment occurring subsequent to the original field effort that might extend beyond the original
survey corridor would be subject to repeated field surveys.
The surveys focused on waters of the U.S. including, but not limited to, wetlands, ditches, and
streams, as well as federally protected plants and wildlife and their habitats. The biologist used
a hand-held TrimbleTM global positioning system (GPS) unit that was loaded with the project
centerline, 200 -foot -wide survey limits, roads, NHD lines, NWI polygons, and ownership
layers to ensure accurate survey and mapping of the project area. Photographs were taken of all
recorded features and are presented in Appendix B.
3.2.1 Wetlands
The presence/absence of wetlands was evaluated in the field using routine delineation methods
described in the U.S. Army `orps of n ineers Wetlands Delineation Manual (USACE 1987),
and in the Regional Supplement to the Corps o Engineers Wetland Delineation Manual: Great
Plains Region (Version 2. )) (USAGE 2010), hereinafter referred to as the Regional
Supplement. Wetlands are characterized by a predominance of hydrophytic vegetation,
presence of hydric soils, and presence of wetland hydrology. While surveying the alignment,
the biologist scanned the survey corridor for visual evidence of changes in vegetation
composition consistent with prolonged inundation or saturation, and changes in surface features
indicating the presence of wetland hydrology. If any of these circumstances were present, the
biologist recorded data necessary to complete a Regional Supplement Wetland Determination
Data Form, providing documentation of the presence or absence of wetlands. Determination of
wetland habitat type, if present, was based on the classification system developed by Cowardin
et al. (1979). Wetland boundaries, if observed, were recorded at the upland/wetland interface
on the GPS unit.
3.2.1.1 Vegetation
The predominance of hydrophytic vegetation for each wetland plot was determined in the field
by estimating the percent cover of the species present and assigning the appropriate wetland
indicator status, as listed in the National Wetland Plant List (Lichvar et al. 2014). Hydrophytic
4 SWCA

and non-hydrophytic (or upland) plant species were differentiated by their respective indicator
status, such as facultative AC), facultative wetland (FACW), obligate (OBL), facultative
upland (FACU), and upland (UPL). A plant community with greater than 50% dominant
hydrophytes (MC or wetter) was determined to meet the USACE criteria of a h droph tie
community.
3.2.1.2 S oils
Hydric soil determinations were made according to criteria listed in the Regional Supplement
and Field Indicators of Hydric Soils in the United States: A Guide for Identifyin - and
Delineating Hydric Soils, Version 7.0 (U.S. Department of Agriculture, Natural Resources
Conservation Service 2010). Where possible, soil pits were excavated to a depth of up to 20
inches, and the soil profile was then described by horizon. Each horizon was evaluated for soil
color; thickness; the color, abundance, and contrast of redoximorphic features; soil texture; and
comparison to mapped soils, Munsell soil color charts were used to determine the color of the
soil matrix and redo imorphic features (Munsell Color 200 9). The soil profile was studied for
hydric soil indicators listed in the Regional Supplement. If the soil profile displayed one or
more hydric soil indicators, a positive hydric soil determination was made.
.,1. Hydrology
Wetland hydrology was determined in the field by considering frequency and duration of
inundation, visual observation of saturation in the upper 12 inches of the soil profile, and the
presence of other primary wetland hydrology indicators, such as oxidized root channels, water -
stained leaves, water marks, sediment deposits, or algal matting. Secondary indicators used to
determine wetland hydrology included surface soil cracks, drift deposits, drainage patterns,
saturation signatures on aerial photographs, or the FAC-Neutral test. If the area displayed one
or more primary hydrology indicators or two or more secondary hydrology indicators, a positive
hydrology determination was made.
3.2.2 Waterbodies
The presence/absence of lotic systems (e4g4, creeks, rivers, arroyos, human -made ditches;
collectively "streams") was identified in the field pursuant to guidance provided in the USACE
Regulatory Guidance Letter No. 08-02 regarding ordinary high water mark (OHWM)
identification (USAGE 2005). An OHWM is a line on a shore established by fluctuations of
water and indicated by physical characteristics such as a clear, natural line impressed on the
bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the
presence of litter and debris; or other appropriate means that consider the characteristics of the
surrounding areas. The OHWM is the defining element for identifying the lateral limits of non -
wetland waters. Federal jurisdiction over a non -wetland water of the U.S. typically extends to
the OHWM. All waterbodies were recorded on a Trimble GPS unit and photographs were taken
at each site.
3, .3 Sensitive Species and Wildlife Habitats
SWCA reviewed the list of federally listed species for Weld County, Colorado, available
±rough the U.S. Fish and Wildlife Service (USFWS) website (USFWS 2017) to determine the
species that are evaluated in this report. In total, 10 species are listed for the project area (rabble

(MBTA). The MBTA makes it illegal for anyone to take, possess, import, export, transport,
sell, purchase, barter, or offer for sale, any migratorybird, or the parts, nests, or eggs of such a
bird, except under the terms of a valid permit issued by the U F S. Several avian species
protected by the MBTA, including raptors, are likely to occur within the project area.

SWCA reviewed color aerial imagery of the project area and performed a desktop analysis of
potential federally listed species that might be present in the vicinity of the project area. SWCA
also conducted qualitative comparisons of the habitat requirements of listed species with
vegetation communities or landscape features observed in the project area during the field
surveys. When an area met the habitat requirements of a listed species, that area was mapped
in a geographic information system I) format using a handheld GPS unit (Trimble).
The Colorado -listed (Colorado Parks and Wildlife 2017) threatened western burrowing owl
(Athene cunicularia) nests in prairie dog (Cynomys sp.) colonies in northeast Colorado. All
prairie dog colonies located within the survey corridor were recorded and mapped during the
field surveys.
31.4 Noxious Weeds
Plant species listed on the Colorado Department of Agriculture's noxious weed list were
surveyed for in the field. A complete inventory of weed occurrences allows for proper planning
to control the spread of weeds in the project area. In the case that a noxious weed occurrence
was identified in the field, a GPS location or boundary, field notes, and photographs were
recorded to document this location.
3,3 FIELD MAPPING
The spatial extent of features was recorded in the field using Trimble GPS units with sub -meter
accuracy. Coordinates of vertices were recorded along the perimeter of each wetland and other
potential waters of the U.S. Field data were processed using Arcl" ap 1045 software. The acreage
of wetlands and other waters of the US. overlapping the survey corridor and construction ROW
was determined by calculating the area where the project footprint and any delineated features
overlap.

4.2 WATERBODIES
The project crosses three named, earthen ditches; the Speer Canal, Bowles Seep Canal, and
Beebe Seep Canal were delineated within the survey corridor. Additionally, an excavated pond
was delineated within the survey corridor. The pond has a hydrologic nexus with the Speer
Canal via additional excavated ponds to the north. The general characteristics and OHWMs of
each waterbody were recorded and are summarized in Table 2. The locations of these features
are illustrated in Figure 2 in Appendix A and a photograph of each surveyed waterbody is

4.3 SENSITIVE SPECIES IE D WILDLIFE HABITATS
Based on the desktop review and field surveys conducted by W A, federally listed threatened
and endangered species are unlikely to occur in the project area. No designated critical habitats
for endangered species are present in the project area and therefore the project will likely result
in "no effect" to federally listed species (USFWS 2017).
Two raptor nests were identified with 045 mile of the survey corridor during field surveys. The
two nests identified are summarized in Table 3 and their locations are illustrated in Figure 2 in
Appendix A.

performed. Colorado Parks and wildlife guidelines recommend no surface occupancy (above
ground, permanent structures) within 0.3 mile of an active red-tailed hawk nest at any time and
no human encroachment of an active red-tailed hawk nest within 0.3 mile from February 15
through July 15 (Colorado Parks and Wildlife 2008). If construction activities are planned
between February 15 and July 31, follow-up surveys to confirm nest status are recommended
for these identified nests. If construction activities are to occur while raptors are actively
nesting, SWCA recommends additional mitigation measures such as nest monitoring or
consultation with Colorado Parks and Wildlife.
Migratory bird nesting (non -raptor) generally starts in northern Colorado on or shortly after
April 1 of each year. The META prohibits the take or destruction of all nests. Other federally
protected migratory bird species may nest in the project area, so any ground disturbance
activities commencing after April 1 should be preceded by nesting bird surveys to ensure
compliance with the MBTA.
One prairie dog colony, approximately 13 acres in size, is located partially within the survey
corridor and has the potential to support nesting burrowing owls. Colorado Parks and Wildlife
(2017) guidelines recommend burrowing owl protocol surveys to confirm the presence or
absence of nesting burrowing owls to avoid inadvertent take (Le., disturbance, harassment,
mortality) if construction is scheduled to occur between March 15 and October 31. If nesting
burrowing owls are observed, consultation with Colorado Parks and wildlife should occur to
determine any necessary protection measures. The colony is identified as PIS 1 AWEO5 5 in
Figure 2 in Appendix A.
4.4 NOXIOUS WEEDS
One noxious weed occurrence, spotted knapweed (Centaurea stoebe) T 1 AwEO 13) is located
within the survey area. The infestation is approximately 20 plants within a 0.25 -acre area and
its location is illustrated in Figure 2 in Appendix A. The species is considered a Colorado List
B noxious weed (Colorado Department of Agriculture 2017), required by state law to be
suppressed where found.
5.0 SUMMARY
Within the survey corridor, three named canals and one excavated pond were identified. The
pipeline will be installed viahorizontal bore technique under all water features. Two raptor
nests and one prairie dog colony were also located and documented during the field survey.
The identification of water features within the project area supporting OHWMs does not
necessarily indicate that these features are subject to Clean Water Act Section 404 jurisdiction.
SWCA biologists believe these features may have downstream connectivity which means they
are likely jurisdictional, however only the USACE can make determinations regarding the
status of waters of the U.S. For the purposes of this project, Discovery DJ Services assumes
that each of these features is subject to USACE jurisdiction and proposes to either avoid impacts
or to adhere to all terms and conditions of Nationwide Permit 12 for utility lines when working
within or adjacent to these features.

EXECUTIVE SUMMARY
Discovery Di Services, LLC, contracted SWCA Environmental Consultants to complete a
cultural resource review for 5.97 linear miles of proposed pipeline west of Hudson, Weld
County, Colorado (the Milton West pipeline). The resource review considered a 400 -foot -wide
corridor centered on the pipeline for potential direct project effects, and a 1 -mile -wide corridor
for potential indirect project effects. Discovery DJ Services, LLC, provided the centerline via
KMZ file format. As a part of this desktop review, a limited field reconnaissance was conducted
in proximity to wetland and waterbody crossings. No other field surveys were completed. The
purpose of this review is to identify any significant cultural resource constraints associated with
the development of the pipeline.
Three historic canals (Beebe Seep Canal, Bowles Seep Canal, and the Speer Canal) and six
potentially historic roads (Weld County Road 12, Weld County Road 35, Weld County Road
37, Weld County Road 41, Bowles Canal Road, and State Highway 52) are the only cultural
resources identified in this desktop review that may be adversely affected by this project.
SWCA Environmental Consultants recommends bring the pipeline below these resources to
avoid physical damage to the resources. No areas within the review area possess a high potential
of containing previously undocumented buried archaeological deposits.

INTRODUCTION
Discovery DJ Services, LLC, contracted SWCA Environmental Consultants (SWCA) to
complete a cultural resource review for 5.97 linear miles of proposd pipeline west of Hudson,
Weld County, Colorado (the Milton West pipeline) (Figure 1). The resource review considered
a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 -
mile -wide corridor for potential indirect project effects. SWCA conducted a review of cultural
resource records for the pipeline, including a file search through the Colorado Office of
Archaeology and Historic Preservation (OAHP) COMPASS database on September 13, 2017.
This review was performed to evaluate the nature of the historical occupation of the area and to
assess the potential for previously unrecorded cultural resources. Additionally, SWCA
reviewed General Land Office L) maps, maps from the U.S. Geological Survey (USGS)
U.S. Topo and Historical Topographic Map Collection, and aerial imagery.

o. .IIP FILE SEARCH RESULTS
The OAHP geographic information systems (GIS) records search identified eight previous
cultural resource inventories that have been conducted within 1 mile of the project centerline,
two of which are within 200 feet of the proposed pipeline centerline. One of these previous
inventories was conducted for the Front Range Pipeline project, and the other was conducted
for a fiber optic line build (Table 1).

The OAHP file search results identified eight previously recorded sites or site segments within
1 mile of the proposed centerline. Only one site, a historic corral, water pump, and windmill
that has been determined not eligible for the National Register of Historic Places (NRHP)
(5WL7296), was mapped in the OAHP records within 200 feet of the proposed centerline. Of
the seven other sites between 200 feet and 1 mile from the proposed centerline, none are
determined or recommended to be eligible for NRHP nomination.
SWCA therefore recommends that none of the cultural resources identified in the OAHP file
search results within 1 mile of the proposed centerline will be adversely affected by the project,
and no further work is recommended for these resources.
HISTORIC PROPERTY REVIEW
In an attempt to identify significant historic properties not present in the OAHP records, SWCA
reviewed historic maps of the project area, including the 1863 GLO plat for Township (T) 1
North (N), Range (K) 66 West (WT), the 1867 GLO plat for T1N, R65 , and the 1869 plat for
the Denver Pacific Railway (Bureau of Land Management 2016) . Historic topographic maps
containing information mapped between 1949 and 1971 were also reviewed. The GLO plats
depict no features of potential. significance.
Many of the first roads in the region tended to follow property lines and the section lines
surveyed by the GLO (Autobee and Dobson -Brown 2003:E-52). In 1885, the Colorado General
3 A
Desktop Cultural Resource Review

Weld County, _ Colorado
Assembly passed legislation that allowed county commissioners to declare any section or
township line on the public domain a public highway.
Six potentially historic named roads weld County Road 12, Weld County Road 35, Weld
County Road 37, Weld County Road 41, Bowles Canal Road, and State Highway 52 have
been mapped in proximity to the proposed centerline (U. S . Census Bureau, Geography Division
2016). Five of the six roads have been upgraded and/or paved; all remain in use today. Based
on the historic topographic maps, Bowles Canal Road appears to have originally functioned as
a service road for the Bowles Seep Canal (5WL4843), but this road does not appear to have
been formally recorded. To avoid adverse effects to any of these potentially historically
significant roads, SWCA recommends avoidance by boring the pipeline under these roads.
Given the amount of modem infrastructure in the immediate vicinity, indirect adverse effects
caused by pipeline construction on either side of these roads are unlikely.
Several buildings and canals are mapped on the historic topographic maps within the project
vicinity (USGS and Esri 1949a, 1949b, 1950, 1951, 1969, 1971) . The canals are still intact and
include segments that have yet to be formally recorded and are therefore not contained in the
OAHP files. Where these corresponded with potential U.S, Army Corps of Engineers
jurisdictional waters of the United States, field reconnaissance was performed and the
canals/ditches were recorded accordingly (discussed below).
By 1949, several farmsteads had occupied the project vicinity (USGS and Esri 1949a, 1949b,
1950, 1951), and these are represented by mapped buildings on the historic topographic maps.
The number of mapped buildings remains consistent without substantial increase through 1971
(USGS and Esri 1969, 1971) . Undocumented historic farm complexes can best be understood
within the context of the Historic Farms and Ranches of Weld County multiple property listing
(Whitacre and Simmons 1990). The historic buildings cannot be entirely confirmed to be extant,
but OAHP records for the few that have been formally documented indicate that farmsteads
primarily not eligible for the NRHP are present in the vicinity. Considering the current level of
modem visual disturbance in the area, the proposed pipeline is unlikely to result in significant
indirect adverse effects to any NRHP-eligible historic buildings in the vicinity of the project.
Aside from the ditch segments and scattered historic buildings, the historic map review
identified one north -trending transmission line west of the project and several unnamed,
unimproved roads on the 1949 topographic map (USGS and Esri 1949a). No other potential
historic resources were identified in the project area vicinity that are not already identified in
the OAHP records.
The land patent search of the eight sections crossed by the proposed pipeline identified three
that were patented by the Union Pacific Railway Company and one that was patented by the
Denver Pacific Railway and Telephone Line/Union Pacific Railroad under the Union and
Central Railroad Grant of 1862. Portions of four sections were patented under the Sale -Cash
Entry Act of 1820 and the Homestead Act of 1862.

Three ditch/canal segments were newly recorded for the current project: the Bebee Seep Canal
(5WL275312), the Bowles Seep Canal (5WL4843.5), and the Speer Canal (5WL1485123).
The Beebe Seep Canal segment (5WL2753.12) was recorded between Weld County Road 12
on the south, and Colorado State Highway 52 on the north. This segment is approximately 0.5
mile long. The Beebe Seep Canal is a significant part of the historically complex Standley
Irrigation System from 1909-1910 crossing Adams and Weld Comities. Given this association
with early agriculture, thecanal is eligible for NRHP nomination, and this segment contributes
to this eligibility. The canal segment is located outside of the proposed project -related
disturbance, but at its closest is approximatelyapproxirnately 15 feet from proposed disturbance. SWCA
recommends avoidance of project -related disturbances by maintaining an avoidance buffer of
at least 50 feet from this historic canal segment. If this avoidance buffer cannot be maintained,
SWCA recommends fencing of the historic canal segment to limit disturbance to the resource.
The segment is located adjacent to a two -track road, pasture, and cultivated and formerly
cultivated fields, and the disturbance associated with pipeline construction will be temporary
and wall not result in indirect effects to this historic canal segment.
The Bowles Seep Canal segment (5WL4843.5) was recorded through a pasture in Sections
and 7, T1 , R65W. W. The segment extends from approximately 200 feet north of Weld County
Road 12 to 200 feet south of Weld County Road 12 for a distance of approximately 400 feet.
The Bowles Seep Canal is the western bifurcation of the Beebe Seep Canal (Neely et aL 2004;
Wilson et al. 2007), and as such is eligible for NRHP nomination due to its significant
association with early agriculture in the region, including the aforementioned Standley
Irrigation. System; the newly recorded segment is intact and contributes to this eligibility.
SWCA recommends avoidance of project -related disturbances by boring to place the pipeline
at a sufficient depth under this canal. The segment is located in a pasture and passes underneath
Weld County Road 12, and the disturbance associated with pipeline construction will be
temporary and will not result in indirect effects to this historic canal segment.
The Speer Canal segment (5WL,1485.23) was also recorded through pasture and a fallow field
in Sections 11 and 12, TIN, R6 W. The segment extends for approximately 0.35 mile and is
bounded by a material yard to the west-southwest and the edge of the survey corridor to the
east-northeast. The Speer Canal was originally constructed in 1889 by the Hudson Ditch and
Reservoir Company as the Western. Hudson Lateral, but was later renamed the Speer Canal and
became a significant part of the historically complex Standley Irrigation System from 1909
1910 crossing Adams and Weld Counties (Driver and Kerns 2015). Given this association with
early agriculture, the canal is eligible for NRHP nomination, and this segment contributes to
this eligibility. SWCA recommends avoidance of project -related disturbances by boring to
place the pipeline at a sufficient depth under this canal. The segment is located in a pasture and
adjacent to a heavily disturbed materials yard and ranching complex, and the disturbance
associated with pipeline construction will be temporary and will not result in indirect effects to
this historic canal segment.

GEOLOGIC FACTORS AFFECTING SITE POTENTIAL
The project area is located in an area of predominantly low relief. Alfisols, Aridisols, and
Entisols are the most common soil orders across the project area, but Mollisols are also
represented along the far north -trending eastern end of the p j ect area (Esri and Natural
Resources Conservation Service 2014). The upland plains, which are characteristic of the
eastern half of the project area and contain predominantly Alfisois and Axidisols, are prime
farmland when irrigated (Esri and Natural Resources Conservation Service 2014), and the
major factor affecting the preservation of buried archaeological material is the agricultural and
urban development in the area. The western two-thirds of the project area contain
predominantly Entisols that have weathered from underlying Cretaceous- and Tertiary -aged
sedimentary rocks (Tweto 1979) and are unsuitable farm land. As a result, much of this area
appears to remain uncultivated, with oil and gaswells and associated pipelines and roads being
the major disturbance through this area. In the cultivated uplands, a mantle of soil may have
buried archaeological deposits, but cultivation has disturbed the upper soil horizons. The intact
Entisols in thewestern project area are likely not sufficiently stable to have encased significant
cultural deposits. Depositional settings favorable to the preservation of buried archaeological
material are also commonly associated with floodplains and terraces, however the proposed
centerline does not cross major drainages associated with such deposits. Given this depositional
setting and extensive cultivation, the project area is interpreted as having a low potential to
contain significant buried archaeological deposits.
SUMMARY AND RECOMMENDATIONS
Three historic canal segments (Beebe Seep Canal, Bowles Seep Canal, and the Speer Canal)
and six potentially historic roads (Weld County Road 12, Weld County Road 35, Weld County
Road 37, Weld County Road 41, Bowles Canal Road, and State Highway are the only
cultural resources identified in this desktop review that may be adversely affected by this
project. Although these resources are located in their historical agricultural setting with limited
residential and oil and gas developments, the proposed Milton West pipeline alignment largely
follows section lines and roadways with existing disturbance. As a result, the visual settings of
these historic resources are unlikely to be compromised by the proposed pipeline, especially
once the pipeline corridor has been revegetated. SWCA recommends using boring to avoid
physical damage to the majority of these resources, and avoidance within 50 feet and/or fencing
of the Beebe Seep Canal at the eastern end of the project area. By adhering to these avoidance
measures, construction and operation of the Milton West pipeline should result in no adverse
effects to significant known historic properties. No areas within the review area possess a high
potential of containing previously undocumented buried archaeological deposits. However, in
the event that such a discovery is made, SWCA recommends that the resource be formally
recorded and evaluated for NRIIP eligibility by a permitted archaeologist.
