SUBJECT: USR12-0046, Nelson Ranches
A Use by Special Review permit for an oil and gas processing facility along with equipment
storage and staging.
The Weld County Public Works Department has reviewed this proposal. This project falls under the Use
by Special Review Standard, Weld County Code, Chapter 23, Article II, Division 4, Section 23. Staff
comments made during this phase of the Use by Special Review process may not be all-inclusive, as
other issues may arise during the remaining application process.
COMMENTS:
CR 118 is a local gravel road and requires a 60-foot right-of-way at full build out. There is presently a 60-
foot right-of-way. This road is maintained by Weld County. Pursuant to the definition of SETBACK in the
Weld County Zoning (23-1-90), the required setback is measured from the future right-of-way line.
An access permit has been approved for this project. Please show the approved accesses on the Plat
and label them with the approved Access Permit number (AP12-00047).
Traffic to the gas plant is minimal. Due to the staging and storage of equipment and 3 semi trips per day
access improvements and a water quality feature will be required.
Access improvements are required and shall include 60' radiuses to accommodate turning trucks and
tracking control to prevent the tracking of mud and debris onto the County roadway. The standard
recommended tracking control for gravel roadways includes a double cattle guard at the exit of the site.
Other means of tracking control may also be proposed.
An improvements and road maintenance agreement is required for this site. Public Works will provide a
draft of the agreement after the Board of County Commissioners hearing for this project. Road
maintenance requiring dust control and repair of any damages to the County roadway due to hauling from
the site will be included in the agreement.
There shall be no parking or staging of vehicles on CR 118.
Please provide a water quality depression for this site downstream of the storage and equipment parking
area. This area will need to be shown on the plat and labeled as "Water Quality — No Build or Storage
Area". Please see the attached procedures for calculating the required Water Quality volume.
This area IS NOT in a Special Flood Hazard Area (SFHA) as determined by the Federal Emergency
Management Agency (FEMA).
REQUIREMENTS:
1. Add the following conditions of approval to the plat:
a. Show the access points on the Plat and label them with the Access Permit number
(AP12-00047).
b. An Improvements and Road Maintenance agreement is required. Access improvements
shall include 60' radiuses and tracking control including double cattle guards the exit of
the site.

c. Provide a water quality depression for the site. Show and label the depression on the
plat.
2. Add the following development standards to the plat:
a. Pursuant to Chapter 15, Articles I and II of the Weld County Code, if noxious weeds exist
on the property or become established as a result of the proposed development, the
applicant/landowner shall be responsible for controlling the noxious weeds. All
vegetation, other than grasses, needs to be maintained at a maximum height of 12
inches until the area is completely developed.
b. The historical flow patterns and run-off amounts will be maintained on site in such a
manner that it will reasonably preserve the natural character of the area and prevent
property damage of the type generally attributed to run-off rate and velocity increases,
diversions, concentration and/or unplanned ponding of storm run-off.
c. There shall be no parking or staging of vehicles on CR 118

From: Bethany Salzman, Zoning Compliance Officer
Subject: USR12-0046 Referral
Upon review of my case files and computer, an active Zoning Violation (ZCV12-00154)was noted. This
violation was initiated due to the operation of an oil & gas Support and Services business without first
completing the necessary Weld County Zoning Permits. This case has not been presented to the Weld
County Court Magistrate through the Violation Hearing process; therefore, an investigation fee is not
required at this time.
Due to records release laws, staff no longer tracks complainant information, but please be aware it is
staff's policy to no longer accept staff initiated complaints.
This application if approved by the Board of County Commissioners and once a plat is recorded will
correct the violation. If this application is denied, all oil &gas operations and associated activities and/or
storage shall be removed from the property within 30 (thirty)days of denial or the violation will proceed in
court accordingly.

A Site Specific Development Plan and Special Review Permit for a Mineral Resource Development Facility including Oil and
Gas Support and Service (gas plant) in the A(Agricultural) Zone District
Parcel: 028518100004
Dear Sir/Madam,
The Weld County Building Department has reviewed the history and investigated any complaints or violations
that accompany the parcel the establishment resides on. The findings are as followed:
There are no building permits on file forany of the structures on the site. A building permit will be required
for each structure as well as for the covers over the compressor units. An engineer will need to investigate
the foundations and provide a letter for each foundation stating that it meets the current adopted Weld
County Codes.
Electrical permits will also be required. Any existing electrical wiring that has not been permitted will need to
be inspected and the proper permits pulled.
Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change
the occupancy of a building or structure,or to erect, install, enlarge, alter, repair, remove, convert or replace
any electrical, gas, mechanical or plumbing system, or to cause any such work to be done, shall first make
application to the building official and Weld County to obtain the required permit.
For further information or comments please contact the Weld County Building Department.
Sincerely,
