RE: Submittal for change of USR Roggen Disposal, USR-481:81:27
Dear Ms. Chester:
As recently requested by Ms. Etcheverry, Weld County Department of Public
Health and Environment, the following request to change the USR for the former
Roggen Disposal facility is submitted.
The requested modifications pertain to item number 18 of the USR.
"Upon cessation of operations at the site all structures shall be removed to thirty(30)inches below grade and all
ponds or pits shall be filled and graded so as to conform with the surrounding terrain. The special use permit
area shall be reclaimed to the condition prior to this operation."
In the site Closure plan submitted to the Weld County Department of Public
Health and Environment, and the Colorado Department of Public Health and
Environment in November 2000, it was recommended that three former ponds be kept
in places following the completion of the other closure activities and subsequent
environmental investigations. The majority of these activities have been completed at
this time. Subsequent activities to be performed, after the certified closure related to
the soil environmental issues by the county and the state, include the regrading and
seeding of the pond embankments for stabilization purposes.
It is intended that these pond areas will ultimately be used as part of the
livestock grazing activity in the area. Such use and the shape and contours of the
existing ponds would conform to the landscape in the area.
If you have any questions or comments, please do not hesitate to contact me at
(970) 352-2644,cell 970-213-1279.

Subject: Roggen Disposal, USR-481:81:27
We have reviewed the September 24, 2001 letter from John Mahoney concerning the Roggen Disposal.
The letter requests that the existing ponds remain as they currently exist and not be regraded as required
by development standard#18. We have no concerns with allowing the ponds to remain and do not
consider this to be a substantial change from the permit. Please note that all other structures, piping, etc.
have been removed in accordance with standard#18.
If you have any questions, please call me at 2214. Thanks

1 l '47.. 6 MEMORANDUM
TO: Board of County Commissiower
igikp DATE: September 2001
COLORADO FROM: Trevor Jiri.4 & Cindi Etcheverry, Department of
Public Health and Environment
SUBJECT: Roggen Disposal, Recommendation
The Department of Public Health and Environment recommends that this hearing be
continued until March 5, 2002. Our recommendation is based upon progress made by the
facility owner towards closure of the facility and to allow adequate time for final closure
activities to occur.
The following activities have taken place since previous hearing:
• Sludges and contaminated soils were removed from the facility and disposed in an
approved facility. Confirmatory samples have been obtained by the facility's
consultant, John Mahoney, and results are pending.
The following items are expected to occur before the next scheduled hearing date:
• Results of the confirmatory samples will be provided to the Weld County and
Colorado Departments of Public Health&Environment. In the event sample results
are within established clean-up limits no additional removal will be required.
However, should the results indicate that unacceptable quantities of petroleum
products remain in the soils, additional sludge and soil removal will be required.
• The disposal ponds will be reseeded with a native grass seed mixture. The ponds
will be reseeded in January or February using a "cool" weather seed mixture as
recommended by Jerry Alldredge of the CSU Agricultural Extension Office.
Trevor Jiricek discussed each of the above with the facility's owner, Mike Cervi, and the
facility's consultant, John Mahoney. Both verbally indicated that they are in concurrence
with our recommendation.
Please do not hesitate to ask any questions that you may have.

MEMORANDUM

TO: Trevor Jiricek
COLORADO Department of Public Health & Environment
FROM: Kim Ogle, Planner Ill\p
SUBJECT: Roggen Disposal, USR 481
The Department of Planning Services has reviewed the letter from John Mahoney,
representative for Mike Cervi dated September 24, 2001 concerning Roggen Disposal. The
letter requests that the existing ponds remain as they currently exist and not be
regraded as required by Development Standard number 18 of USR 481. If the
Department of Public Health and Environment has no concerns with this modification,
the Department of Planning Services concurs with this request. That being said,
Staff has no concerns with allowing the ponds to remain so long as this modification
to the plan does not change the overall landscape plan required through the
reclamation permit. Further, Planning Staff does not consider this to be a substantial
change from the permit.
