1.0 USR QUESTIONAIRE
Extraction Oil & Gas, LLC (Extraction) has prepared a Use by Special Review application
for the proposed Vetting 15-H well pad (Vetting) located in the Northwest 1/4 of Section 15,
Township 5 North, Range 65 West of the 6th P.M within unincorporated Weld County.
More specifically the proposed project is located northeast of 24th Street and Cherry
Avenue on a 35.823 acre parcel of land owned by 7N, LLC. Extraction has a surface use
agreement in place with the land owner to conduct oil and gas operations on a portion of
the property. Refer to the vicinity map included with this application.
Extraction is concurrently filing a Recorded Exemption application to resolve an illegal lot
subdivision regarding Lot A of RE -304. The proposed well pad will be on Lot B of the
current Recorded Exemption application.
1.1 Question #1: Explain in detail, the proposed use of the property.
It is our understanding the property is located within the USR boundary of application USR
665:85:3. This USR was approved in 1985 for oil and gas production facilities associated
with the Sandusky wells for Basin Exploration, Inc. Per the Use by Special Review plat,
the boundary of USR 665 was the south half of the northwest quarter of Section 15,
Township 5 North, Range 65 West. The existing USR included one existing well, the
Sandusky #1 and its associated production equipment consisting of a separator, tank
battery, and access road. Additionally, the existing USR allotted for a future well, the
Sandusky #2, a future separator, future tank battery, and separate access road. Per
Colorado Oil and Gas Commission (COGCC) records, the Sandusky #1 (API #05-123-
12218) is still a producing well now operated by Noble Energy, Inc. The well denoted as
the Sandusky #2 on the existing USR, appears to have been drilled as the Eisenman 22-
15 in 1993 and is also operated by Noble Energy, Inc. The associated production
equipment appears to have never been installed in the location depicted on the plat.
Extraction proposes a partial vacation of USR 665:85:3 to remove parcel number 0961-
15-2-00-014 (to be known as Lot B) from the USR boundary. Please refer to sheet 2 of
the Special Review Plat map which provides a limits of vacation exhibit.
This vacation is proposed so that a new USR application can be processed for this
property. Extraction is proposing to a multiple oil and gas well pad which would include up
to 24 horizontally drilled wells, 24 separators, a tank battery consisting of up to 22 tanks,
4 vapor recovery units, 8 emission control devices, and 2 vapor recovery towers. The
proposed facility would have internal access roads between the wellheads and production
equipment and would access onto Cherry Avenue. A new access onto Cherry Avenue is
proposed. The access road will be 24 feet wide and will be constructed with large radii to
facilitate truck turning movements. With the proposed well pad, the existing Sandusky #1
well would be plugged and abandoned and the associated production equipment would
be removed.
3
1.2 Question #2: Explain how this proposal is consistent with the intent of the Weld
County Code, Chapter 22 of the Comprehensive Plan.
The Vetting project is consistent with Section 22-5-90, Oil and Gas Deposits, and Section
22-5-100, Oil and Gas Goals and Policies, of Chapter 22 of the Weld County Code.
Section 22-5-90, Oil and Gas Deposits:
The proposed operation meets the intent of both Sections A and B. Section A states that
oil and gas development is an integral part of the County economy and Section B states
that in addition to in -state use, oil and gas resources are important exports for Colorado
and lessen the country's dependence on foreign supplies. This proposed use directly
aligns with both sections as this project will support the County's oil and gas industry and
promote local oil and gas exploration ultimately reducing the need for foreign import.
Section 22-5-100, Oil and Gas Goals and Policies:
The proposed operation meets the intent of Sections A through C as shown below.
• The proposed project promotes the reasonable and orderly exploration and
development of oil and gas mineral resources through coordinated communication
between the surface owner and the mineral owners (OG Goal 1).
• The proposed project promotes the use of directional (horizontal) drilling to protect
surface rights of agricultural lands and possible future land uses (OG Goal 2).
• The proposed project encourages the clustering of oil and gas well sites through use
of directional (horizontal) drilling (OG Goal 2).
• The proposed project encourages the use of minimal drill window areas through use
of directional (horizontal) drilling (OG Goal 2).
• The proposed project will be designed to prevent surface and groundwater
contamination by providing secondary containment around tanks and other production
equipment (OG Goal 3).
• All oil and gas wells drilled will follow COGCC regulations pertaining to well cementing
to prevent commingling of water, oil, and gas into other formations (OG Goal 3).
1.3 Question #3: Explain how this proposal is consistent with the intent of Weld
County Code, Chapter 23 (Zoning) and the zone district in which it is located.
The proposed site is located in a Low -Density Residential (R-1) Zone District. According
to the Weld County Code Chapter 23, oil and gas production, storage, support and service
facilities are permitted on land zoned as R-1 when approved by the Use by Special Review
(USR) process. Currently, oil and gas operations are conducted on this property as part
of an existing USR. The proposed use will expand and replace the existing operations to
efficiently drill surrounding materials from one single location. This well pad will allow
minerals to be developed that may otherwise be stranded due to the COGCC and local
government regulations pertaining to well pad siting and setbacks from building units. The
proposed pad has been designed to maximize setbacks from surrounding homeowners
as well the nearby school building.
1.4 Question #4: What type of uses surround the site (explain how the proposed use
is consistent and compatible with the surrounding land uses).
4
• The 32.6 acre parcel to the south is located in Weld County and is zoned R-1. Current
use of the property is a mix of flood irrigated farm land, grazing land, and single family
residential property.
• The 15.7 acre parcel to the south is located in Weld County and is zoned R-1. Current
use of the property is as a single family residential property.
• The 1.0 acre parcel to the south is located in Weld County and is zoned R-1. Current
use of the property is as a single family residential property.
• The 47.6 acre parcel to the west, west of Cherry Avenue, is located in Weld County
and is zoned R-1. Current use of the property is flood irrigated farm land and as a
single family residential property.
• The 1.0 acre parcel to the north is located in Weld County and is zoned R-1. Current
use of the property is as a single family residential property.
• The 19.5 acre parcel to the north is located in Weld County and is zoned R-1. Current
use of the property is an elementary school (Bella Romero Academy 4-8 campus).
• The 9.8 acre parcel to the north is located in Weld County and is zoned R-1. Current
use of the property is flood irrigated farm land.
• The 29.0 acre parcel to the north is located in Weld County and is zoned R-1. Current
use of the property is flood irrigated farm land.
The proposed site is zoned Low Density Residential (R-1) and, per Weld County Code, oil
and gas production, storage, support and service facilities are permitted when approved
by the Use by Special Review process. Currently, oil and gas operations are conducted
on this property as part of the existing USR. The proposed use will expand and replace
those operations to efficiently drill surrounding minerals from one single location. This well
pad will allow minerals to be developed that may otherwise be stranded due to the COGCC
and local government regulations pertaining to well pad siting and setbacks from building
units. The proposed pad has been designed to maximize setbacks from surrounding home
owners as well as the nearby school building. Additionally, Extraction will implement
various best management practices (BMPs) during the drilling, completion, and production
phases of this project to minimize impacts to surround land owners. BMPs that will be
implemented include:
• Installation of temporary sound walls during drilling and completion activities.
• If feasible, powering the drilling rig off of a high line power line, which would eliminate
the noise caused by the generators on the rig. This noise mitigation solution requires
proper infrastructure supplied by the power company and therefore may be out of
Extraction's hands.
• During drilling, Green Completion Practices and a closed loop system will be used for
the drilling fluids. No open pits will be used.
• Use of a local or nearby water source to fill the Modular Large Volume Tanks (MLVTs)
during completions operations therefore reducing truck traffic by not hauling water to
5
the site.
• Extraction contracts with a third party environmental compliance Specialist Company
to complete regular General Tank Battery and Fugitive Emissions Inspections and
Optical Gas Imaging Surveys at the proposed tank battery.
• Install Emission Control Devices (ECD) and Vapor Recovery Units (VRU) to reduce
the VOC vapors that are generated from crude oil condensate storage tanks. The ECD
and VRU units reduce VOC emissions by at least 95% through combustion and
sequestration.
• Silica dust suppression will be implemented during the completion process so that dust
generated from the silica sand used during hydraulic fracturing will be contained using
a vacuum system.
• Extraction utilizes technology that completely automates the facility. By using such
technology, Extraction can remotely monitor the location. In the event the facility is not
operating under normal conditions, the automation system will immediately notify
Extraction and has the ability to perform an emergency shut down if necessary.
• Extraction is committed to using Lease Automatic Custody Transfer (LACT) meters to
load trucks on this pad. The LACT meter has many advantages over traditional truck
loading including:
o Less likely to have spills because of improved connections,
o LACT pump is electric driven and enclosed, reducing noise,
o Truck loading times are at least two times faster, reducing the amount of time a
truck is on location,
o Truck vent lines are sent to the Emission Control Device which is 95% efficient
destruction of VOC,
o Oil haulers no longer need to climb to the top of tanks and open thief hatches to
gauge tanks. This eliminates the emissions from blowing down tanks and keep
drivers safe by not exposing them to tank vapors.
1.5 Question #5: Describe, in detail, the following:
1.5.1 Number of people who will use this site
During drilling and completion of the wells, Extraction will contract with various companies
to provide drilling, hydraulic fracturing, and general construction services. Upon
completion of the wells, an Extraction employee will monitor the wells daily. Extraction will
contract with a water pumper and oil gatherer to collect the produced water and oil. See
below for anticipated number of employees.
1.5.2 Number of employees proposed to be employed at this site
As stated above, Extraction will contract with various service providers to drill, complete,
and construct the wells and well pad. Additionally, Extraction personnel will be working on
site during these phases. Once the wells are completed, the facility will be monitored daily
by an Extraction employee. The site itself will not have any employees.
6
The following is an anticipated breakdown of number of employees per phase (either
Extraction or contract employee):
• Drilling: 20 employees working in two shifts
• Completions: 50 employees working in two shifts
• Flowback: 20 employees
• Production: 1 to 2 employees for monitoring
1.5.3 Hours of operation
The hours of operations will depend on the phase of the project. During the drilling phase,
operations will be 24 hours a day, seven days a week. It is estimated that one horizontal
well of this length would take up to 12 days to drill. During the completions phase of this
project, completions operations will be conducted 24 hours a day, seven days a week. It
is anticipated that completions operations will last up to 10 days per well. Construction of
the well pad, earthwork operations, and construction of the facilities will be conducted
during typical business hours but may occur seven days a week depending on schedule.
Once the facility has entered the production phase, operations will occur 24 hours a day,
seven days a week, however the site will only be accessed daily for inspections by an
Extraction employee.
1.5.4 Type and number of structures to be erected (built) on this site
The proposed well pad will consist of up to 24 directionally or horizontally drilled wells and
the following production equipment:
• 18 Oil Tanks: store produced oil, 500 bbl capacity, welded steel, 25 ft tall
• 2 Water Tanks: store produced water, up to 500 bbl capacity, fiberglass or welded
steel, 25 ft tall
• 24 Separators: separates production fluid into their constituent components of oil,
gas, and water
• 2 Meter Houses: meters produced gas, oxygen levels
• 4 Vapor Recovery Unit (VRU): compresses natural gas emitted off the oil
• 8 Emission Control Device (ECD): eliminates excess gas that cannot be recovered
by the VRU
• 2 Vapor Recovery Tower (VRT): Used to further separate gas entrained in the oil
1.5.5 Type and number of animals, if any, to be on this site
No animals are anticipated on site.
1.5.6 Kind of vehicles (type, size, weight) that will access this site and how often
The traffic associated with the proposed use will depend on the phase of the project. The
duration of each phase will ultimately depend on the number of wells drilled. The
anticipated daily traffic is as follows:
Daily Vehicle Activit Trips

5
It is anticipated that the majority of "trucks" accessing the site will be Combo Units (class
8-13), however some Single Units (class 4-7) are also expected. It is assumed supervisors
will be driving pickup trucks and contract employees will be driving personal vehicles.
During the completions phase it is anticipated that contracted employees part of the
hydraulic fracturing crew will be bused to and from the site, therefore the number of daily
trips by employees is reduced. Please refer to the traffic narrative for more information.
1.5.7 Who will provide fire protection to the site
This property is located in the Western Hills Fire Protection District. It is our understanding
that this district currently provides fire protection through a contract with the City of Greeley
Fire Department.
1.5.8 Water source on the property (both domestic and irrigation)
The proposed use will not require an on -site water source. During drilling and completion
operations, modular large volume tanks will be temporarily installed on -site to store water.
It is anticipated that these tanks will be filled from a local source through use of temporary
above ground water line. No trucking of water is anticipated.
1.5.9 Sewage disposal system on the property (existing and proposed)
There is no sewage disposal system on the property and one is not proposed. During
construction, drilling, and completion operations portable sanitary facilities will be provided
on -site pursuant to COGCC Rule 602.f.
1.5.10 If storage or warehousing is proposed, what type of items will be stored
After drilling and completion of the wells and construction of the facilities, no warehousing
or storage of equipment or materials is proposed. However, produced oil and water will be
stored within the tank battery until it is transported off -site.
1.6 Question #6: Explain the proposed landscaping for the site. The landscaping
shall be separately submitted as a landscape plan map as part of the application
submittal.
The proposed landscape plan will include perimeter fencing and additional tree barriers
along the west and north property lines. Along the west and north site of the property a
wood privacy fence will be installed to provide screening from Cherry Avenue and
surrounding property owners. Additionally, trees will be installed in front of the fence to
provide additional long term screening. Access to the site will be controlled by an
automatic gate that will control access via a key pad. The south and east sides of the
property will be fenced with chain link to ensure that no unauthorized personnel will be
8
able to access the facility. Please refer to the screening and landscape plan included with
this submittal.
1.7 Question #7: Explain any proposed reclamation procedures when termination of
the Use by Special Review activity occurs.
Termination of the Use by Special Review activity is not expected until the oil and gas
wells are no longer producing or until the wells are no longer financially viable. At that
time, the location will be reclaimed per COGCC Rule 1004. Final Reclamation of Well
Sites and Associated Production Facilities. Per COGCC regulations, the wells will be
plugged and abandoned and the all debris, abandoned gathering line risers and flowline
risers, and surface equipment shall be removed within three (3) months of plugging a well.
In addition, financial assurance has been posted with the COGCC to guarantee final
reclamation of the site is completed.
1.8 Question #8: Explain how stormwater drainage will be handled on the site.
The site will be re -graded to create a suitable pad to conduct oil and gas drilling operations
as well as to maintain historic drainage patterns. The property is nearly flat and therefore
minimal earthwork will be needed to create the drilling pad. The access road and
production facilities area will be graded to provide drainage from the road surface and
away from equipment. Since the road will be constructed of aggregate material, the access
road will be pervious allowing for stormwater infiltration. Per the Colorado Oil and Gas
Conservation Commission (COGCC), containment devices shall be constructed around
crude oil, condensate, and produced water storage tanks and shall enclose an area
sufficient to contain 150% of the largest single tank. On this site, an engineered
containment system will be utilized around the tank battery to meet the secondary
containment requirements. As a result, all stormwater that falls within the limits of the
proposed tank battery will be retained within the containment system. All retained
stormwater will be collected and hauled off -site for disposal.
Water quality ponds will be constructed to improve water quality and allow for sediment
and contaminants to settle out prior to leaving the site. Please refer to the drainage
memorandum included with this submittal.
1.9 Question #9: Explain how long it will take to construct this site and when
construction and landscaping is scheduled to begin.
It is anticipated that this pad will be drilled in two phases. Phase one will consist of initial
well pad construction, drilling of 10 to 12 horizontal wells, completion of the wells, and
construction of the production facility. Initial pad construction and phase one drilling is
anticipated to last approximately 120 days. Completions operations and flowback of phase
one is anticipated to last an additional 120 days. Phase two of the project is expected to
have a similar timeline.
9
Perimeter landscaping will be installed after phase one is completed. Interim reclamation
of the location will be completed in accordance with COGCC Rule 1003. Interim
Reclamation.
1.10 Question #10 Explain where storage and/or stockpile of wastes will occur on this
site.
Storage and/or stockpiling of wastes are not expected on -site. During construction of the
pad, solid waste generated by the site will be collected and disposed of by a contracted
waste disposal company. Disposal will follow the rules and regulations as defined by the
CDPHE.
Please list all proposed on -site and off -site improvements associated with the use
(example: landscaping, fencing, drainage, turn lanes, etc.) and a timeline of when
you will have each one of the improvements completed.
No off -site improvements are proposed as a part of this project.
Onsite improvements will include perimeter fencing and landscaping along the west and
north property lines. Along the west and north sides of the property a wood privacy fence
will be installed to provide screening from Cherry Avenue and surrounding property
owners. Additionally, trees will be installed in front of the fence to provide additional long
term screening. The access to the site will be controlled by an automatic gate that will
control access via a key pad. The south and east sides of the property will be fenced with
chain link to ensure that no unauthorized personnel will be able to access the facility.
Please refer to the screening and landscape plan included with this submittal.

On -site Bio-Remediation for Drill Cuttings
This document outlines the operational requirements to be used when applying bio-remediation
techniques to maintain compliance with COGCC Rules 907 and 1000 Series Reclamation
Regulations, and the Drill Cuttings Management Policy (9/15/14).
1. Mixing and Treatment:
A. All cuttings shall be mixed on location
B. Cuttings shall be mixed with additives. The amount of additives shall be determined
based on laboratory analysis of untreated cuttings.
C. Mixing shall be performed with equipment to ensure contact between the cuttings and
additives
D. Additives
i. CMC — polymer absorbent, non-toxic, non -hazardous
ii. Oppenheimer Piranha — bioremediation of hydrocarbons
iii. Water soluble calcium —chemical reduction of SAR
2. Stockpile Management:
A. Treated, solidified cuttings shall be stored on location in individual well stockpiles. One
stockpile per well. Each stockpile shall be marked with the name of the well.
B. Stockpiles shall be windrows with a height as tall as practical. Taller windrows aid in
the retention of warmth increasing microbial activity
C. Leachate shall be managed by absorbent material. The inherent properties of CMC
reduces leachate levels of TDS to below standards based on laboratory analysis.
D. An earthen berm, one foot in height, shall be constructed around the stockpile(s) to
minimize storm water runoff
E. As the solidified cuttings dry, a protective crust layer will form on the surface of the
stockpile. This crust layer helps retain moisture and heat within the stockpile while
also protecting the native landscape from windborne contaminated particulate. Care
shall be taken by the Operator and all contractors to minimize stockpile disturbance
until a properly trained soil sampling technician visits the site.
3. Sampling & Testing:
A. The stockpile of treated cuttings will be sampled and tested according to standard
laboratory and sampling protocols and COGCC table 910-1. Stockpiles will be
sampled in increments no greater than 100 cubic yards. Ten samples shall be
taken from each segment of the stockpile of treated drill cuttings, mixed and then
one composite sample will be used for testing. Samples will be taken from the

stockpile in such a way as to preserve any potential volatile organic compounds. Ten
random samples shall be taken of the stockpile of subsoil for use as a source for
background data.
B. After the cuttings have achieved the threshold limits specified in table 910-1, the
treated material will be thin spread on the well site and incorporated into the
reclamation fill material.
C. A permanent record of the laboratory analysis shall be maintained by the Operator.

Re: Traffic Analysis, Vetting 15-H Well Pad, Amended USR 665:85:3
Overview
As requested at the pre -application meeting by county staff, a summary of the traffic associated with the
proposed Vetting 15-H Amended USR application has been prepared.
As is stated in the project narrative, the proposed site will include up to 30 wells and the associated production
equipment including a tank battery, separators, and emission control devices. Ultimately the traffic associated
with the proposed project will depend on the number of wells drilled and the production of the wells. It is likely
that the wells will be drilled in phases. This traffic impact report has been prepared for a 12 well program. It is
anticipated that Extraction will drill 24 wells in two phases with any additional wells being drilled at a future time.
The traffic associated with the proposed project has been analyzed in four phases: construction and drilling,
completions, flowback, and production. The construction and drilling and completion phases will generate the
most traffic, however these phases represent a temporary condition. Long term traffic associated with the
production of the site will be minimal and will likely decrease as the wells age. Additionally, to reduce the traffic
associated with the completions phase of the project, Extraction is committed to using a local source to provide
water used during hydraulic fracturing. By using a local source, such as existing ditches or fire hydrants in the
area, water will not be trucked to this location.
Trip Generation
Since oil and gas production operations are not listed in the ITE Trip Generation Manual as a use, the anticipated
traffic trips provided are based on our knowledge and experience of operating other oil and gas facilities of this
scale in nearby areas.
Daily traffic associated with each phase is provided below, as is the estimated duration and operational hours of
each activity based on a 12 well program and no trucking of water for completions activities.

It is anticipated that the majority of "trucks" accessing the site will be Combo Units (class 8-13), however some
Single Units (class 4-7) are also expected. It is assumed supervisors will be driving pickup trucks and contract
employees will be driving personal vehicles. During the completions phase it is anticipated that contracted
employees part of the hydraulic fracturing crew will be bused to and from the site, therefore the number of daily
trips by employees is reduced. It is also anticipated that the employees working during the drilling and completion
phases will work in shifts. Two twelve hour shift are planned, the day shift will operate from 6:00 AM - 6:00 PM
with the night shift being from 6:00 PM - 6:00 AM. Approximately two thirds of the employees will work the day
shift with the remaining employees working the night shift. Therefore peak site trips will most likely occur at shift
change hours and will consist mostly of passenger cars or equivalent vehicles. Truck activity will occur randomly
throughout the 24 hour day.
Trip Distribution
A new access from Cherry Avenue is being proposed approximately 500' feet from the intersection of Cherry
Avenue and 24th Street. This is the most suitable access, as the existing oil and gas access road is located on
the adjacent property and is in close proximity to the residential home. The proposed access will keep traffic
further away from the surrounding homes and will be constructed to better accommodate truck turning
movements.
The anticipated haul route from the access is to travel south on Cherry Avenue (County Road 43) and turn east
onto 24th Street. From 24th Street traffic will turn south onto U.S. Highway Business 34. From U.S. Highway
Business 34 traffic will either head east or west on U.S. Highway 34 depending on their final destination.
It is anticipated that 100% of the trips will used the haul route proposed above. However, should Weld County
prefer an alternative route, Extraction is willing to discuss options with staff.
Impacts & Mitigation
The traffic associated with the production phase of the proposed project is minimal and therefore no roadway
improvements to Cherry Avenue or 24th Street are anticipated. The proposed access from Cherry Avenue will
be constructed with large turn radii to facilitate truck turning movements and double cattle guards will be

installed to minimize sediment tracking. If necessary a dust palliative will be applied to the access road as
needed.
Conclusion
The long term impacts of the traffic associated with the proposed project will be minimal and Extraction is
committed to working with Weld County and the City of Greeley to ensure that the most appropriate haul route
and proper mitigation measures are utilized. Please feel free to contact us if you have any questions.

Thanks for the email . What kind of documentation do we need from the City of Greeley?
Also — I talked with Morgan last week. As you know we are proposing a new access for Lot B, north of the existing shared
access between Lots A and B . After talking with Morgan we are going to discuss closing the shared access with the
owners of Lot A. Once we talk with the owners of Lot A I will be reporting back to Morgan .

The proposed access is in an acceptable location for the City. There would not be any negative impact to traffic in the
proposed location per our standards. The City does not do access permits so I hope this email will suffice for the
County's purposes. If they need additional documentation let me know.

Derek,
We in the process of going through a Recorded Exemption - RECX16-0043 (and a USR - USR 16-0009) with Weld County
for two lots located northeast of the intersection of Cherry Avenue and East 24th Street. It appears that a portion of
Cherry Avenue is owned by the City of Greeley. The two existing accesses, one for Lot A (2350 Cherry Ave) and the other
a shared access for both lots enter Cherry Avenue within the City of Greeley portion. Our planner, Diana Aungst has
asked that we coordinate the two existing accesses with the City.
Both accesses are existing and will remain the same. The existing access for Lot A will continue to be used for the
residence. The shared access along the property line between the two lots would continue to be used for
agriculture/ditch rider use. As part of the USR we are working with Weld County to obtain a new access for oil and gas
traffic, which would be located to the north. Please see attached exhibit.
Does the City have any concerns with the continued use of these accesses?
I wasn't sure who to coordinate this request with, so please forward on if Development Review is not the right
department.

RE: Drainage Analysis
Minor Amendment to USR 665:85:3
Vetting 15-G
OA Job Number: 015- 1882
Ms. Aungst,
Olsson Associates has completed an analysis of the stormwater drainage for the proposed
Vetting 15-G project located in the northeast corner of the intersection of E 24`h Avenue and
Cherry Avenue. For the following calculations a drainage area of approximately 36 acres was
defined . Please see the included exhibits for area designation.
The property is located within the South Delta Basin as defined in Figure 2 . 1 Basin Vicinity Map
from the City of Greeley Comprehensive Drainage Plan . The property currently drains from the
south to the north with an average slope of 0.5 percent. Currently, all stormwater that falls within
the property surface flows to the north and discharges in to the Greeley #3 Ditch , and ultimately
reaches the Cache la Poudre.
The existing conditions of the property were analyzed first to determine the percent impervious
of the site. Currently, this portion of the property is farmed and was therefore analyzed as
undeveloped open space. A field road access traverse the property, accessed from Cherry Ave
and bisecting the site as it turns north . The field access road was considered to be packed
gravel in the calculations. The property in its current condition was determined to be
approximately three percent impervious.
Next, the percent impervious was calculated for the developed condition . The proposed
improvements on the property consist of installing thiRy wells, associated production equipment,
and an access road . For the purposes of calculating the percent imperiousness of the
developed site, the access road was assumed to consist of packed gravel . The property in its
developed condition was determined to have a composite percent impervious of approximately
eight percent.
It was determined that the developed conditions of the proposed use will have little impact on
the imperviousness of the site, only increasing the percent impervious by five percent. Due to
the design and construction of the proposed use, stormwater that comes into contact with the

majority of the production equipment will be self-contained and prevented from leaving the site.
Therefore, due to the negligible increase in percent imperviousness and installation of
secondary containment devices, a full detention pond will not be provided on -site.
To protect water quality, a water quality pond located on the north side of both the well and tank
pads is proposed. The water quality capture volume (WQCV) was calculated in accordance with
the Urban Drainage and Flood Control District's (UDFCD) Urban Drainage Criteria Manual,
Volume 3, Chapter 3, Section 3.
For the purposes of providing water quality for the proposed improvements, the site was divided
into two basins. Basin 1 encompasses the proposed well pad and Basin 2 contains the
production facilities pad. For both basins the WQCV was computed based on the
imperviousness of the catchment area.
For Basin 1 the composite percent imperviousness was determined to be seven percent, the
required WQCV using a 40 hour drain time was computed to be 2,572 cubic -feet. The water
quality pond designed for Basin 1 has a capacity to detain approximately 9,303 cubic -feet of
stormwater runoff, as designed the WQCV will be at a depth of 1.6 feet and the water quality
pond will have approximately 1.5 feet of freeboard. Refer to the attached exhibits and
calculations for additional information.
Basin 2 was determined to have a composite percent imperviousness of twelve percent; the
required WQCV using a 40 hour drain time was computed to be 1,697 cubic -feet. The pond
designed for the WQCV of Basin 2 has the capacity to detain approximately 10,155 cubic -feet of
stormwater; as designed the WQCV will be about 1.75 feet deep. Refer to the attached exhibits
and calculations for additional information.
Both these water quality ponds are designed to discharge through infiltration. Utilizing this
discharge method the water quality pond for Basin 1 will completely discharge within
approximately six hours and the water quality pond for Basin 2 is designed to have a drain time
of approximately seven and a half hours. Refer to the attached exhibits and calculations for
additional information.
Please contact us if you require any further information.
Sincerely,
Chris Hill

Preface
Soil surveys contain information that affects land use planning in survey areas. They
highlight soil limitations that affect various land uses and provide information about
the properties of the soils in the survey areas. Soil surveys are designed for many
different users, including farmers, ranchers, foresters, agronomists, urban planners,
community officials, engineers, developers, builders, and home buyers. Also,
conservationists, teachers, students, and specialists in recreation, waste disposal,
and pollution control can use the surveys to help them understand , protect, or enhance
the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil properties
that are used in making various land use or land treatment decisions. The information
is intended to help the land users identify and reduce the effects of soil limitations on
various land uses. The landowner or user is responsible for identifying and complying
with existing laws and regulations.
Although soil survey information can be used for general farm, local , and wider area
planning, onsite investigation is needed to supplement this information in some cases.
Examples include soil quality assessments (http://www.nres. usda.gov/wps/portal/
nres/main/soils/health/) and certain conservation and engineering applications. For
more detailed information, contact your local USDA Service Center (http://
offices.sc.egov. usda.gov/locator/app?agency=nres) or your NRCS State Soil
Scientist (http://www.nres. usda.gov/wps/portal/nres/detail/soils/contactus/?
cid=nres142p2_053951 ).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic
tank absorption fields. A high water table makes a soil poorly suited to basements or
underground installations.
The National Cooperative Soil Survey is a joint effort of the United States Department
of Agriculture and other Federal agencies, State agencies including the Agricultural
Experiment Stations, and local agencies. The Natural Resources Conservation
Service (NRCS) has leadership for the Federal part of the National Cooperative Soil
Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

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

Soil Map
The soil map section includes the soil map for the defined area of interest, a list of soil
map units on the map and extent of each map unit, and cartographic symbols
displayed on the map. Also presented are various metadata about data used to
produce the map, and a description of each soil map unit.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the landscape,
however, the soils are natural phenomena, and they have the characteristic variability
of all natural phenomena . Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if ever, can be mapped without including areas of other taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used .
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments
on the map provides sufficient information for the development of resource plans. If
10
Custom Soil Resource Report
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions. Each
description includes general facts about the unit and gives important soil properties
and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other characteristics that affect their use. On the basis of such
differences, a soil series is divided into soil phases. Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the soils or miscellaneous areas are somewhat similar in all
areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present or
anticipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform. An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material
and support little or no vegetation. Rock outcrop is an example.
