RE: USR-1131
Dear Sirs:
Planning Commission for the City of Fort Lupton reviewed the above mentioned referral at our
regular meeting of August 10, 1996.
The Planning Commission had the following concerns:
The Planning Commission was concerned with how the use would impact the future site of the
Historic Village which is across the river from the proposed arena. The Planning Commission
would like to know if the road is a dedicated road or a private road and how will this use affect
the other users of the road. The commission is also concerned with how the increase in traffic
would affect the Historical Society. The commission also had a concern because the Historic site
currently has a shooting range which is across from the arena.
The application indicates that the roping arena will not be a commercial use but the applicant has
indicated that the arena will be used for team roping 3 days a week. The sketch of the site also
shows a parking area which would indicate there would be some commercial use of the site.
Another inconsistency in the application is the source of water. The applicant states that Deep
Rock water will be provided for the people attending the events. The application also indicates
that the applicant has applied with the State for a well permit. Dick Wolfe, a member of Planning
Commission, works for the State and he indicated that wells such as the one requested are not
962065
allowed for commercial use but are allowed for family roping. Dick felt the applicant might be
indicating that the arena is not a commercial use in order to drill the well.
The Planning Commission for the most part had no objection to the use but thought their
concerns should be addressed. If you have any questions or if we may be of further assistance
please call us at 346-0326.

Environmental Protection Services has reviewed this proposal; the following
conditions are recommended to be part of any approval:
1. The applicant shall remove, handle, and stockpile manure from the
livestock area in a manner that will prevent nuisance conditions. The
manure piles shall not be allowed to exist or deteriorate to a condition
that facilitates excessive odors, flies, insect pests, or pollutant

2. The facility shall be in compliance with the Colorado Guidelines for
Feedlot Runoff Containment and Weld County Zoning Ordinance, Section 47,
prior to final approval of the proposed use.
3. All liquid and solid wastes shall be stored and removed for final disposal
in a manner that protects against surface and groundwater contamination.
4. No permanent disposal of wastes shall be permitted at this site.
5. Waste materials shall be handled, stored, and disposed in a manner that
controls fugitive dust, blowing debris, and other potential nuisance
conditions.
6. Fugitive dust shall be controlled on this site.
7. The maximum permissible noise level shall not exceed the commercial limit
of 60 db(A) , as measured according to 25-12-102, Colorado Revised
Statutes.
8. Any existing septic system(s) which is not currently permitted through the
Weld County Health Department will require an I.S.D.S. Evaluation prior to
the issuance of the required septic permit(s) . In the event the system(s)
is found to be inadequate, the system(s) must be brought into compliance
with current I.S.D.S. regulations.

COLORADO From: Dave Sprague, Lead Electrical Inspector
SUBJECT: Steve Lance property located at SW4 SW4 Section 30 T02N
R66W
Steve Lance acquired an electrical permit for a pole barn to house his horses. Included in
permit EP45467 was the wiring for the structure, underground wiring to the pole barn, and a
permanent electrical meter to supply power to the barn. This permit has been finaled.
Nothing else on his property has been permitted nor inspected. This includes the wiring to the
arena lightning and the announcer's booth located at the NW portion of the arena. All the
electrical work has been completed and is in use. Once an electrical permit has been
approved, all inspections will need to be done. This will do doubt include uncovering trenches
which contain electrical wiring and removing portions of the wall coverings at the announcer's
booth.

Re: Case Number USR-1131
Dear Ms. Eastin:
Our Board of Directors wishes to go on record as cautioning the applicant, Steve Lance, that
directly east of the South Platte River from his proposed use, our organization operates a black
powder shooting range. Shoots are held monthly, at least, and he needs to be aware of this, in
case the noise would be a bother for any events he might hold.
The Society has contacted the applicant, and he indicates this will not be a problem for him.
This is for information only, and is not a letter of opposition.
Sincerely,

Dear Ms . Eastin:
We have received the application from Steve Lance for a
Site Specific Development Plan and a Special Review Permit
for a Roping Arena. After our review of the application and
a site visit by Natural Resources Conservation Service
personnel, we have the following comments :
SOILS
*****
While the roping arena is removing cropland from
production, none of this land is prime farmland. The arena
and parking area are now bare, presenting a potential soil
erosion problem. Also, there was standing water in the
parking area because of poor soil drainage . By paving the
parking area or covering it with gravel, soil erosion could
be prevented and vehicle safety improved.
WASTE HANDLING
**************
The applicant stated that manure produced by animals at
the facility would be applied to nearby hay fields . Soil
and manure testing should be performed to determine
appropriate rates of application. We are including
information on soil and manure testing for the applicant ' s
use . The high water table and close proximity of the Platte
River necessitate that precautions be taken to minimize the
hazard of ground and surface water pollution. There is also
visible crusting on the soil surface from accumulated salts,
which could become worse if manure is applied.
Weld County Planning Dept.
0CT 2 4 1996
ism tdr e L„„;
962065
The applicant also mentioned that the steers used for
roping are turned out to drink from the river. If this is
the case, the animal operation comes under Colorado' s
Confined Animal Feeding Regulations . These state that if
animals are confined for more that 45 days per year in an
area devoid of vegetative cover and come into contact with
waters of the state (i .e . the Platte River) , then the animal
operation must prevent manure discharge into state waters
and provide a beneficial use for the manure . This makes
soil and manure testing especially important .
STREAMBANK PROTECTION
*********************
If the steers are turned out to drink from the Platte
River, they should be confined to a small area of the
streambank. Frequent animal traffic will damage vegetation
along an area susceptible to erosion and interfere with
wildlife . If the steers are turned out to graze a pasture
adjacent to the Platte River, it should not be during times
when waterfowl will be using the streambanks for nesting.
Fencing can be used to prevent access to the river during
these times . If an alternative source of water is provided,
the river would be protected from animal traffic, and this
operation would no longer be considered a concentrated
animal feeding operation.
Thank you for giving us the opportunity to comment on
this matter. If you have
any
questions

Regulatory Controls
The Agricultural Chemicals and Groundwater Protec-
tion Act(SB 90-126)does not directly address the use of
manure because it is not classified as a commercial fertilizer.
However,the proper management of N fertilizer requires —
accounting for all N sources,including manure. Best Man-
agement Practices(BMPs)prescribed under SB 90-126 will
address manure management as a component of proper N ==
fertilizer management to reduce NOS leaching. Sewage

(5 CCR 1003-7),and is not directly addressed by these
BMPs.
