SITE SPECIFIC DEVELOPMENT PLAN AND USE BY SPECIAL
REVIEW (USR) QUESTIONNAIRE
John R. Moser-Morwai Water Project
The following questions are to be answered and submitted as part of the USR
application. If a question does not pertain to your use, please respond with "not
applicable", with an explanation as to why the question is not applicable.
1. Explain, in detail, the proposed use of the property.
The proposal is to utilize an existing water storage pond for a water transfer
station for the transfer and transport of water to commercial needs including
agriculture, construction and oil and gas production. The water storage pond is a
Use by Right but has been included in the USR application as part of the water
transfer facility. Upon termination of the water transfer station the storage pond
will remain in use for the agricultural needs of the owner.
The facility will have a liquid natural gas (LNG) transfer station for fueling
vehicles on site in conjunction with the water transfer. The LNG fueling facility will
make use of mobile LNG fueling trailers left on site. The LNG facility will
predominantly serve any LNG powered vehicles using the water transfer facility
described above, though there may be occasional usage by LNG powered fleets
(e.g. Weld County Public Works). The mobile facilities are designed to be
replaced and refilled off site. Typically LNG is stored in double walled, vacuum
insulated tanks for maximum safety. Any onboard equipment requiring fuel runs
on the natural gas in the main tank. Such facilities are becoming a common
stopgap as permanent LNG infrastructure is developed.
Vehicle and equipment storage is proposed on the north end of the facility. There
is also potentially a water storage tank to be located at the north end of the pond.
2. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 22 (Comprehensive Plan).
This USR application has been prepared utilizing the process outlined in the Weld
County Code and Procedural Guides. The Guiding Principles of the
Comprehensive Plan found in Section 22-1-120 states, "Land use changes must
afford flexibility based on the specific location and the particular circumstances
encountered within the locality. It is also important to weigh the cumulative
impacts that specific land use changes will have."
This proposal is respectful of surrounding uses. There is an existing dairy farm
immediately north and east of the property and an 1-3 zoned property including a
tire disposal site and salvage yard to the south.
The application is consistent with Section 22-2-20 G. A.Goal 7. "County land use
regulations should protect the individual property owner's right to request a land
use change. 2. A.Policy 7.2. Conversion of agricultural land to non urban
residential, commercial and industrial uses should be accommodated when the
subject site is in an area that can support such development, and should attempt
to be compatible with the region."
The site is located directly across from an 1-3 zone district and the regular truck
route along CR 39 and CR 41 between LaSalle and Hwy 52 and 1-76 at Hudson.
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.
The proposal is for an oil and gas support business in the Agricultural Zone. This
proposal is allowed in the Ag Zone as a Use by Special Review as called in
Chapter 23, 23-3-40.
23-3-40 A. Mineral resource development facilities including:
2. Oil and Gas Support and Service.
Adequate provision has been made to protect the health, safety and welfare of
the inhabitants of the neighborhood and the County. Operation Standards as
found in Section 23-2-260 of the Weld County Code were consulted in preparing
this application.
4. What types of uses surround the site? Explain how the proposed use is
consistent and compatible with surrounding land uses.
The surrounding area has multiple uses including production agriculture,
rangeland, oil and gas production, a USR property for dairy and the 1-3 industrial
zoned property with a salvage yard and a used tire disposal facility.
5. Describe, in detail, the following:
a. How many people will use this site?
It is proposed that 10 full time employees will use this site. The
employees will pick up water trucks and transfer and haul water at regular
intervals throughout the day as needed.
b. How many employees are proposed to be employed at this site?
It is proposed that 10 full time employees will be employed at this site in
the future depending on business conditions.
10 employees will be at the site less than 4 hours per day.
c. What are the hours of operation?
The facility is projected to be operational Monday -Sunday, twenty-four
hours per day.
d. What type and how many structures will be erected (built) on this site?
The only proposed structure not currently in place is a potential water
storage tank with a diameter of approximately 100 feet. There is no
determined timeline for this construction and is included for planning
purposes only.
e. What type and how many animals, if any, will be on this site?
No animals will be on this site.
f. What kind (type, size, weight) of vehicles will access this site and how
often?
Typical vehicles accessing this site include employee and owner vehicles
and water trucks. The following numbers are anticipated upon full build -
out of the site:
Water Trucks: 10 trucks= averaging 100 trips per day
Pickups and cars: 10 per day for full time employees.
g. Who will provide fire protection to the site?
Platteville-Gilcrest Fire Protection District
h. What is the water source on the property? (Both domestic and irrigation)
There are commercial well permits for industrial and irrigation use.
Portable toilet and hand washing systems will be utilized for sanitation for
drivers, if necessary.
What is the sewage disposal system on the property? (Existing and
proposed).
Portable toilet and hand washing systems will be utilized for sanitation for
drivers, if necessary.
J•
If storage or warehousing is proposed, what type of items will be
stored?
Storage and warehousing is not proposed to be a main activity of this
request; however, storage of water trucks and equipment, including tractors
and trailers, service and miscellaneous business supplies will be stored on
site to accommodate daily business requirements.
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. No additional landscaping is planned.
7. Explain any proposed reclamation procedures when termination of the Use by
Special Review activity occurs.
Reclamation procedures include compliance with applicable regulations. Should
the facility be permanently discontinued, the water storage pond will be utilized
for agricultural irrigation storage needs.
8. Explain how the storm water drainage will be handled on the site.
Please see the preliminary drainage report for details.
9. Explain how long it will take to construct this site and when construction and
landscaping is scheduled to begin.
Construction will commence upon approval of the Permit and should be
completed within 6 months to 1 year.
10. Explain where storage and/or stockpile of wastes will occur on this site.
There will be no storage of wastes on this site. All materials will be in the
production stream, recycled or collected in dumpsters and sent to the landfill. Any
wastes produced from employees will be contained in a dumpster and hauled off
regularly by a sanitation service.

URS Memorandum
Date: October 29, 2012
To: Weld County
From: URS - Nathan Walker, PE
Subject: URS Responses to Moser Dairy Comments from Weld County
Attachments: A — Moser Dairy Water Supply Construction Drawings C-03 through C -OS
B — Overflow spillway hydraulics calculation package
The following memorandum and associated attachments provide a formal response to the comments
provided by Weld County documented in the memorandum titled "GDR12-00015, Moser Dairy (4 May
2012).
Weld County Comment 1:
Sheet C-03 of the erosion control and grading plan set shows an overflow spillway at the south end of the
pond. However, no engineering sizing calculations of flow rates or velocities were provided for the
spillway. No invert elevations for the spillway are given on the grading plans. The width of the spillway is
not given on the plans. The plans show a rip -rap pattern for the spillway erosion protection; however no
riprap sizing was provided.
URS Response to Comment 1:
The spillway dimensions riprap sizing are as shown on drawing C-08 (see Attachment A). The spillway
dimensions and hydraulic performance can be summarized as follows:
• Spillway length 10 ft;
• Spillway side slopes 4H:1V;
• Spillway invert EL 4863.5 ft;
• Embankment crest EL 4865 ft;
• Riprap sizing: angular rock graded with 2 inch minimum and 6 inch maximum dimensions; and
• Peak discharge through the spillway during the design 100 year storm event is approximately 3.2
cfs (see Figure 1) which corresponds to hydraulic depth of 2.4 inches at the spillway crest and a
velocity of approximately 4.7 ft/s at the toe of the embankment. The calculations for these flows
are described in the enclosed calculation package (See Attachment 8).

The overflow spillway outfall is not defined; there is no channel or natural flow path for any overflows.
Weld County Road 28 is downslope of the spillway in the path of potential releases; no information was
provided regarding risks to the roadway.
URS Response to Comment 2:
The spillway outfalls to a localized depression and west to the adjacent property and is also where a large
portion of the site discharged prior to development (see Figure 1). The intent of the pond and spillway
design is to limit the developed peak discharge to equal to or less than the undeveloped peak discharge
at this location. This is achieved by the attenuation of the storm event within the pond and by controlled
releases via the spillway. The peak discharge from the design 100 year storm event with undeveloped
conditions is 11.4 cfs and with developed conditions is 10.7 cfs. The peak discharge from the design 5
year storm event with undeveloped conditions is 4.7 cfs and with developed conditions is 4.2 cfs. The
calculations for these flows are described in Attachment B.
A section through the localized depression (see Figure 1) to the west that continues through Weld County
Road 28 is shown on Figure 2. As previously described this is where the spillway flows from the pond are
directed. Using the developed conditions peak discharge described above for the design 100 year storm
event, Manning's equation was used to estimate the depth of flow at the western property boundary
adjacent to Weld County Road 28. The depth of flow at this location is estimated as 0.6 inches. As
shown on Figure 2, Weld County Road 28 sits approximately 10 N higher than the invert of the depression

and is therefore not impacted by releases from the pond by floods up to and in excess of the design 100
year storm event.

A sump area downslope of the spillway extends into the adjacent property to the west; a drainage
easement for overflows to the neighbor may be needed.
URS Response to Comment 3:
Due to attenuation of flows within the pond the peak discharges to the adjacent property (neighbor) to the
west are less undeveloped conditions.
Weld County Comment 4:
Water storage ponds of this size may experience erosion of the intemal banks caused by wind -driven
waves.
URS Response Comment 4:
The pond liner (clay and geo-membrane composite) in the pond extends a minimum of 1 ft above the
maximum pool elevation which protects against erosion from wind driven waves. Above this elevation
there is up to 6 inches of aggregate base course to form the access track around the perimeter of the
pond. For the liner details refer to sheet C-09.
Weld County Comment 5:
The plan set was not wet stamped, signed, and dated by a registered professional engineer.
URS Response Comment 5:
The attached construction drawings in Appendix A have been signed and stamped by a registered
professional engineer. Wet signed and stamped construction drawings will be supplied upon notice that
pending comments have been satisfactorily addressed.

Summary
The Moser Dairy pond is about 6 acres and located at a rural area in the south of Weld County. According
to Weld County Engineering & Construction Criteria (2012), the rainfall depth -duration -frequency curve
maps in the UDFCD Manual arc to be used for determining the frequency storm precipitation depths. The
site location and the interpreted I -hour rainfall depths arc shown in the attached working maps. The
UDFCD CUHP 2005 v1.33 program was then used to generate the 2 -hr rainfall distributions with the given
one -hour rainfall depths. The calculation sheets are attached to this calculation package. For non -urban
areas, the HEC-HMS model is recommended by the County Criteria for determining the developed flow
from a proposed development site.
HEC-HMS program is recommended by County Criteria for the watershed hydrology modeling.
In this study. the generated precipitation distributions of frequency storms were imported into the HEC-
HMS model. The Snyder Unit Hydrograph procedure was used to compute the runoff from the excess
rainfall. Initial loss and uniform loss rate method was applied to estimate the rainfall losses. The required
inputs of the Snyder Unit hydrograph method are the storm lag time and peaking coefficient for each basin.
The basin boundaries were delineated based on the site survey and USGS DEM data. The storm lag time. I.
was defined by SCS in the following empirical relation.
tt=0.6•rt.
where t;= time of concentration and in this study, was computed using Kirpich's Equation (1940).
0.000131,°"
te(hr) Saws
where 1= total flow length in feet, and S= ground slope.
To estimate the discharge at the southwestern property boundary HEC-HMS models were built for both the
undeveloped and developed pond conditions (sec Figure I to 3).
The maximum infiltration rate of I.0 inch9tr, recommended in the UDFCD Criteria was adopted for all
pervious areas under the developed or undeveloped pond conditions. The new Moser Pond water surface
(at normal pool elevation) was assumed to be impervious under the developed conditions.
According to the HEC-HMS Users' Manual, the peaking coefficient typically ranges from 0.4 to 0.8 with
larger values associated with steep -rising hydrographs. Herein, a peaking coefficient of0.4 was selected for
the undeveloped conditions, and a peaking coefficient of 0.8 was selected for the developed conditions.
Table 2 summaries the HEC-HMS input parameters.

For routing of the storm events through the new Moser Pond. the elevation -area relationship and spillway
geometry described in this calculation package were used in the HEC-HMS model for the developed
conditions. Table 3 suuunariies the site discharges for the undeveloped and developed pond conditions at

The spillway at the Moser Pond is 10 ft wide and protected by ripraps. The 100 year storm event would
result in an outflow of approximately 3.2 cfs from the spillway. The corresponding flow depth at the
spillway is approximately 2.4 inches. At the toe of the embankment slope (spillway chute), the velocity was
estimated to be approximately 4.7 fusee, based on the proposed 25% or 1 V:4H slope.
The riprap protection along the spillway was sited for the maximum velocity along the spillway chute.
which is 4.7 ft/sec at the toe of the embankment. Based on the Hydraulic Engineering Circular No. 14 by
U.S. Federal Highway Administration (FHA, 2006)_ a riprap site D5„ was estimated to be about 2 inches.
For conservativeness, a D,,, between 2 to 6 inches would be appropriate for this project.
The calculation sheets are attached for reference.

Weld County Comment 2:
The overflow spillway outfall is not defined; there is no channel or natural flow path for any overflows.
Weld County Road 28 is downslope of the spillway in the path of potential releases; no information was
provided regarding risks to the roadway.
URS Response to Comment 2:
The spillway outfalls to a localized depression and west to the adjacent property and is also where a large
portion of the site discharged prior to development (see Figure 1). The intent of the pond and spillway
design is to limit the developed peak discharge to equal to or less than the undeveloped peak discharge
at this location. This is achieved by the attenuation of the storm event within the pond and by controlled
releases via the spillway. The peak discharge from the design 100 year storm event with undeveloped
conditions is 11.4 cfs and with developed conditions is 10.7 cfs. The peak discharge from the design 5
year storm event with undeveloped conditions is 4.7 cfs and with developed conditions is 4.2 cfs. The
calculations for these flows are described in Attachment B.
A section through the localized depression (see Figure 1) to the west that continues through Weld County
Road 28 is shown on Figure 2. As previously described this is where the spillway flows from the pond are
directed. Using the developed conditions peak discharge described above for the design 100 year storm
event, Manning's equation was used to estimate the depth of flow at the western property boundary
adjacent to Weld County Road 28. The depth of flow at this location is estimated as 0.6 inches. As
shown on Figure 2, Weld County Road 28 sits approximately 10 ft higher than the invert of the depression

and is therefore not impacted by releases from the pond by floods up to and in excess of the design 100
year storm event.

Weld County Comment 3:
A sump area downslope of the spillway extends into the adjacent property to the west; a drainage
easement for overflows to the neighbor may be needed.
URS Response to Comment 3:
Due to attenuation of flows within the pond the peak discharges to the adjacent property (neighbor) to the
west are less undeveloped conditions.
Weld County Comment 4:
Water storage ponds of this size may experience erosion of the internal banks caused by wind -driven
waves.
URS Response Comment 4:
The pond liner (clay and geo-membrane composite) in the pond extends a minimum of 1 ft above the
maximum pool elevation which protects against erosion from wind driven waves. Above this elevation
there is up to 6 inches of aggregate base course to form the access track around the perimeter of the
pond. For the liner details refer to sheet C-09.
Weld County Comment 5:
The plan set was not wet stamped, signed, and dated by a registered professional engineer.
URS Response Comment 5:
The attached construction drawings in Appendix A have been signed and stamped by a registered
professional engineer. Wet signed and stamped construction drawings will be supplied upon notice that
pending comments have been satisfactorily addressed.

Summary
The Moser Dairy pond is about 6 acres and located at a rural area in the south of Weld County. According
to Weld County Engineering & Construction Criteria (2012), the rainfall depth -duration -frequency curve
maps in the UDFCD Manual are to be used for determining the frequency storm precipitation depths. The
site location and the interpreted 1 -hour rainfall depths are shown in the attached working maps. The
UDFCD CUHP 2005 v1.33 program was then used to generate the 2 -hr rainfall distributions with the given
one -hour rainfall depths. The calculation sheets are attached to this calculation package. For non -urban
areas, the HEC-HMS model is recommended by the County Criteria for determining the developed flow
from a proposed development site.
HEC-HMS program is recommended by County Criteria for the watershed hydrology modeling.
In this study, the generated precipitation distributions of frequency storms were imported into the HEC-
HMS model. The Snyder Unit Hydrograph procedure was used to compute the runoff from the excess
rainfall. Initial loss and uniform loss rate method was applied to estimate the rainfall losses. The required
inputs of the Snyder Unit hydrograph method are the storm lag time and peaking coefficient for each basin.
The basin boundaries were delineated based on the site survey and USGS DEM data. The storm lag time, td,
was defined by SCS in the following empirical relation.
=0.6•te
where tc=-- time of concentration and in this study, was computed using Kirpich's Equation (1940).
0.00013L° 77
t (hr) = pies
where L= total flow length in feet, and S ground slope.
To estimate the discharge at the southwestern property boundary HEC-HMS models were built for both the
undeveloped and developed pond conditions (see Figure 1 to 3).
The maximum infiltration rate of 1.0 inch/hr, recommended in the UDFCD Criteria was adopted for all
pervious areas under the developed or undeveloped pond conditions. The new Moser Pond water surface
(at normal pool elevation) was assumed to be impervious under the developed conditions.
According to the HEC-HMS Users' Manual, the peaking coefficient typically ranges from 0.4 to 0.8 with
larger values associated with steep -rising hydrographs. Herein, a peaking coefficient of 0.4 was selected for
the undeveloped conditions, and a peaking coefficient of 0.8 was selected for the developed conditions.
Table 2 summarizes the HEC-HMS input parameters.

For routing of the storm events through the new Moser Pond, the elevation -area relationship and spillway
geometry described in this calculation package were used in the HEC-HMS model for the developed
conditions. Table 3 summarizes the site discharges for the undeveloped and developed pond conditions at
the southwestern property boundary.

The spillway at the Moser Pond is 10 ft wide and protected by ripraps. The 100 -year storm event would
result in an outflow of approximately 3.2 cfs from the spillway. The corresponding flow depth at the
spillway is approximately 2.4 inches. At the toe of the embankment slope (spillway chute), the velocity was
estimated to be approximately 4.7 ft/sec, based on the proposed 25% or 1 V:4H slope.
The riprap protection along the spillway was sized for the maximum velocity along the spillway chute,
which is 4.7 ft/sec at the toe of the embankment Based on the Hydraulic Engineering Circular No. 14 by
U.S. Federal Highway Administration (FHA, 2006), a riprap size D50 was estimated to be about 2 inches.
For conservativeness, a D50 between 2 to 6 inches would be appropriate for this project.
The calculation sheets are attached for reference.

MEMORANDUM
TO: Trevor Jiricek, Lin Dodge, Planning Services
DATE: May 4, 2012
FROM: David Bauer, P.E., CFM
SUBJECT: GRD12-00015, Moser Dairy
On April 24, 2012, Public Works received two copies of an erosion control and grading plan set
labeled as Moser Dairy Water Supply Project. The pond has already been constructed for use by
Noble Energy as a source of water for oil well drilling and completions. Per Weld County Code
Chapter 8, Article XII, a grading permit is required for land disturbance of over one acre. Agricultural
tillage is exempt.
The grading plans show a rectangular pond with a bottom elevation of 4853 feet and a top of berm
of 4865 feet. A twelve foot high water impoundment may be under the jurisdiction of the State
Engineer's office. The base of the west slope of the pond embankment is 17 feet from the west
property line. The south end of the pond embankment is shown as covering an existing gas line.
The site generally slopes in a southeasterly direction.
Sheet C-03 of the erosion control and grading plan set shows an overflow spillway at the south end
of the pond. However, no engineering sizing calculations of flow rates or velocities were provided
for the spillway. No invert elevations for the spillway are given on the grading plans. The width of
the spillway is not given on the plans. The plans show a rip -rap pattern for the spillway erosion
protection; however no riprap sizing was provided. The overflow spillway outfall is not defined; there
is no channel or natural flow path for any overflows. Weld County Road 28 lies downslope of the
spillway in the path of potential releases; no information was provided regarding risks to the
roadway. A sump area downslope of the spillway extends into the adjacent property to the west; a
drainage easement for overflows to the neighbor may be needed. Water storage ponds of this size
may experience erosion of the internal banks caused by wind -driven waves. The plan set was not
wet stamped, signed, and dated by a registered professional engineer.
The applicant is requested to submit engineering calculations and sizing information for the overflow
spillway including peak flows, invert elevations, rip -rap sizing, and downstream conveyance
capacity. The applicant is requested to provide mitigation for erosion of the internal banks caused
by wind -driven waves. The applicant is requested to provide information on the potential risks to
County road 28 in the event of emergency release from the pond.

Morwai Water Project Traffic Narrative
Morwal Water will transport water from the existing storage pond to commercial users
such as agriculture, construction and oil and gas producers. This use will be supported
by an on -site liquid natural gas (LNG) transfer station for fueling transport vehicles.
Water will be transported seven days per week, twenty four hours per day based on
customer needs. Ten tractor -trailer trucks will be based on site as will ten drivers.
Drivers are expected to work an extended shift with flexible start and end times
depending on route travel times. It is expected that each truck will typically make ten
round trips per day. On a daily basis, the water transport facility is expected to
generate 100 truck round trips, 10 truck driver round trips, and 1 - 2 miscellaneous
round trips. LNG trucks are included in this estimate and are expected at a rate of 2 -
3 per week with random arrivals and departures. Accordingly, daily traffic is expected
to be in the range of 115 round trips per day.
Peak hour traffic is expected to occur at the beginning and end of the shift. Since
trucks (and drivers) will depart and arrive at the site based on varying route times, it is
estimated peak hour site traffic will consist of half the trucks arriving at the site and half
the drivers departing the site during the same hour.
All site traffic will use the existing CR 28 access to the dairy. Based on the expected
service area, about 60% of the trucks will turn right onto CR 28 and go west to CR 39.
The remaining 4O% will be equally split between going east on CR 28 or south on CR
41. Since the site driveway functions as an extension of CR 41, albeit slightly offset
north of CR 28, these vehicles essentially travel straight when they enter or exit the
site.
Given that traffic on the area street system is modest, it appears that site traffic can be
easily accommodated.

Re: Moser USR/Water Transfer Facility
Special Use Permit and Site Specific Development Plan
Township 3 North, Range 65 West
Section 29: portion of the E/2SE/4 being a portion of Lots A and 13
Weld County, Colorado
Dear Tim:
This letter is written on behalf of Anadarko E&P Company LP and Anadarko Land
Corp. (`Anadarko Entities") and also Kerr-McGee Oil & Gas Onshore LP ("Kerr-McGee")
with respect to your request for a waiver concerning correct notice of a hearing for an
application for a site specific development plan and special review permit that has been filed
by John Moser ("Applicant") with Weld County ("County) for property located within a
portion of the Ei2SE/4 of Section 29, Township 3 North, Range 65 West, specifically
described as a portion of Lot A and Lot B of RE 2570 ("Property").
The Anadarko Entities own minerals that underlie the Property, and Kerr-McGee own
oil and gas leasehold interests in the Property.
As we discussed in our telephone conversation on March 4, the Anadarko entities
received notice of a hearing before the Weld County Planning Commission by letter dated
January 29, 2013; however the notice letter indicated that the date of the hearing was March 5,
2012, instead of the correct date of March 5, 2013.
This letter constitutes a waiver by the Anadarko Entities and Kerr-McGee as mineral
interest owners to the receipt of correct notice of a hearing scheduled to be held on March 5,
2013 before the Planning Commission for Weld County pursuant to Colorado Revised
Statutes §§ 24-65.5-103, 30-28-133, and 31-23-215 as follows:
Tim Naylor
March 5, 2013
Page 2
1. The Anadarko Entities and Kerr-McGee waive notice pursuant to C.R.S. § 24-
65.5-102(2) of the March 5, 2013 hearing.
2. Notice is waived to the extent that the application applies to the Property so
that Notice is not waived for subsequent applications for development that include other or
additional property for which the Anadarko Entities or Kerr-McGee own minerals or oil and

SITE SPECIFIC DEVELOPMENT PLAN AND USE BY SPECIAL
REVIEW (USR) QUESTIONNAIRE
John R. Moser-Morwai Water Project
The following questions are to be answered and submitted as part of the USR
application. If a question does not pertain to your use, please respond with "not
applicable", with an explanation as to why the question is not applicable.
1. Explain, in detail, the proposed use of the property.
The proposal is to utilize an existing water storage pond for a water transfer
station for the transfer and transport of water to commercial needs including
agriculture, construction and oil and gas production. The pond is roughly 7 acres
in size and is designed to store approximately 36 acre-feet of water. The water
storage pond is a Use by Right but has been included in the USR application as
part of the water transfer facility. Upon termination of the water transfer station,
the storage pond will remain in use for the agricultural needs of the owner.
The facility will have a liquid natural gas (LNG) transfer station for fueling
vehicles on site in conjunction with the water transfer. The LNG fueling facility will
make use of mobile LNG fueling trailers left on site. Typically LNG is stored in
double walled, vacuum insulated tanks for maximum safety. Any onboard
equipment requiring fuel runs on the natural gas in the main tank. Such facilities
are becoming a common stopgap, as permanent LNG infrastructure is
developed. The current mobile units are provided by EnCana and contain roughly
800 diesel gallon equivalent. The current facility is refilled from a tanker truck
every two weeks.
The LNG facility will predominantly serve any LNG powered vehicles using the
water transfer facility described above, though there may be occasional usage by
LNG powered fleets (e.g. Weld County Public Works). LNG powered vehicles will
be able to proceed up the access road to refuel at the LNG fueling facility, turn
around on the circle drive, and proceed to fill at the water transfer facility.
Traditional decal powered vehicles can bypass the LNG fueling facility
completely.
Vehicle and equipment storage is proposed on the north end of the facility.
2. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 22 (Comprehensive Plan).
This USR application has been prepared utilizing the process outlined in the Weld
County Code and Procedural Guides. The Guiding Principles of the
Comprehensive Plan found in Section 22-1-120 states, "Land use changes must
afford flexibility based on the specific location and the particular circumstances
encountered within the locality. It is also important to weigh the cumulative
impacts that specific land use changes will have."
This proposal is respectful of surrounding uses. There is an existing dairy farm
immediately north and east of the property and an 1-3 zoned property including a
tire disposal site and salvage yard to the south.
The application is consistent with Section 22-2-20 G. A. Goal 7. "County land use
regulations should protect the individual property owner's right to request a land
use change. 2. A.Policy 7.2. Conversion of agricultural land to nonurban
residential, commercial and industrial uses should be accommodated when the
subject site is in an area that can support such development, and should attempt
to be compatible with the region."
The site is located directly across from an 1-3 zone district and the regular truck
route along CR 39 and CR 41 between LaSalle and Hwy 52 and 1-76 at Hudson.
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.
The proposal is for an oil and gas support business in the Agricultural Zone. This
proposal is allowed in the Ag Zone as a Use by Special Review as called in
Chapter 23, 23-3-40.

this application.
What types of uses surround the site? Explain how the proposed use is
consistent and compatible with surrounding land uses.
The surrounding area has multiple uses including production agriculture,
rangeland, oil and gas production, a USR property for dairy and the 1-3 industrial
zoned property with a salvage yard and a used tire disposal facility.
