ATTACHEMENTS:
• Technical Revision Submittal Fee — Check #: 25883 in the Amount of $216.00.
• Proof of Placement — Weld County Clerk to the Board

This Technical Revision (TR) is intended to satisfy the concerns expressed in the 20
January 2010 inspection report. Two copies of the TR are included along with the
required fee and proof of placement with the Weld County Clerk to the Board, and
related attachments (see above). As requested in Part 2 of the OMLR inspection report,
included with this submittal is a revised Reclamation Plan Map, since extraction is
essentially complete, except where necessary to effect complete reclamation of the
northwest basin and area fill activity.
1) The boundary determined under Weld County GIS shape file information defines
an area of affected land comprising 102.6± acres, and below the original 120.0± acres
permitted. The difference appears to be based upon differences in measurement from
the original application to the present submittal. The boundary shown with metes and
bounds description comprises the known permit boundary as we understand it today.
Existing contour information based upon physical survey is shown in red for the
southern reservoir; while projected contours for the balance of the affected lands,
including areas of fill and the northwest basin are shown in brown and green based
upon modified USGS Gowanda Quadrangle contour information. Once the northwest
basin is an established reservoir, and fill, soil and revegetation activities are completed,
a revised map will be submitted as part of this submittal showing finished contours
based upon physical survey at the time of release request for this permit.
2) Previously approved inert fill activity is proceeding over the northeast third of the
permit area (areas A & B). While area A fill is nearly complete, approximately 5.0±
acres remain to be filled (area B). All fill activity should be completed within the next
five (5) years, or approximately July 2015.
Since the combined basin areas comprise 45.0± acres, and approximately 0.6± acres
comprise permanent routes along the permit boundary and perimeters of basins, the
balance of lands will require resoiling and revegetation over a portion of the remaining
57.0± acres, including the area of fill, stockpiling and recycling activities. While
resoiling and revegetation will occur within the next year for the southern reservoir, and
within five years of completion of the northwest reservoir, correlated resoiling and
revegetation activities over the fill, stockpile, and recycling locations will be deferred
until all recycling of construction materials and the removal of construction materials
stockpiles is completed, which may continue indefinitely.
3) The southern reservoir is a completed basin of apx. 24.6± acres and has met the
liner construction and test requirements of the State of Colorado Division of Water
Resources Office of the State Engineer. The approval letter from the Office of the State
Engineer dated 28 November 2003 is included with this submittal.
4) The northwest basin is a reservoir presently under construction using the same
methods and standards approved for the southern reservoir. The reservoir lining is
completed over a majority of the location and the liner test is pending. Essentially,
construction of the liner utilized the following methods and standards:
a. Cut a 3 foot x 3 foot keyway at the toe of the basin outslope.
b. Backfill moist to wet shale to the required slope limits or flatter.
c. Compact in approximate 1 foot lifts with a sheepsfoot compactor.
5) Reclamation Status and Clarification of Future Activity:
a. 2.7± acres surrounding the northwest basin (area 2) will require six inches of
soil and vegetation.
b. 5.2± acres surrounding the planned farm storage area will be soiled and
vegetated as a filter strip.
c. 2.6± acres of the current stockpile area on the northeast corner of the
completed southeast reservoir (area 4) will require resoiling and revegetation.
The balance of the area surrounding the southeast reservoir has been soil
and only revegetation is pending.
Soil requirement total = 10.5± acres — total soil volume required = 8470.0± cu.yds.
Soils available on site are shown as:
Soil Stockpile i = 3100± cu.yds.
Varra Companies, Inc. Dakolios Pit — M1984-0036 2
Technical Revision #3 April 2010
Soil Stockpile ii = 5,000± cu. Yds.
Misc. and insitu soils = 500 - 1,000 yards.
Total onsite soil is estimated to be 8,600-9,000± cu.yds. — or sufficient to meet the
reclamation requirement.
Revegetation requirement total = 14.5± acres utilizing the revised mixture as attached.
The reclamation planning and design is further clarified to show permanent roads,
agricultural scalehouse area (area 1), and farm equipment and agricultural materials
stockpile area (area 2). The roadways, scalehouse operations area and farm storage
area will be covered by roadbase to a minimum depth of 4 inches.
An existing seep will be maintained as shown as area C. The seep channel forms and
will retain a near trapezoidal shape with an approximate three foot bottom at varying
depths to the extent necessary to maintain positive flows to the point of exit where
waters continue to St. Vrain Creek through established drainage ways. The waters and
drainage are pre-existing and the new seep segment will essentially assure continued
flows through a channel whose volume exceeds incoming culvert sizes and nominal
flows.
Finally, for clarification, the St. Vrain Sanitation District has plant operations to the
northeast of the permit location. Area E is a 50± wide area set aside for the existing
access and maintenance of this system by St. Vrain Sanitation District. The area will
not be soiled or vegetated to accommodate this system and District access and related
activities.
We trust our reply adequately addresses the concerns of the Office. Naturally, should
you require further clarification or additional information, we look forward to working
with you. Thank-you again for your cooperation and kind assistance.

Dear Jay:
The purpose of this letter is to approve the lining of the above referenced gravel pit. This
approval is based on the site inspection conducted on July 29, 2003 and on the information
provided by you under a cover letter dated October 23, 2003. The estimated pit inflows
from precipitation and groundwater indicate that this pit has been lined to the design
standard referenced in the August 1999 State Engineer Guidelines for Lining Criteria for
Gravel Pits. Meeting the design standard requires that all water inflows and outflows
for this pond must be accounted for on a monthly basis.
Please call me if you have any questions.

RE: Requirements for site release where the site is subject to a Planned Unit Development
Dear Mr. Janes:
You have requested a determination of what would be required to secure bond release at a site
that is subject to a Planned Unit Development (PUD) issued by a county. Specifically, you posed
two questions in your email that I received the morning of April 9, 2008. These questions were:
1) At what point, and by what evidence, will the Division release a portion, or all, lands from a
Division Permit respective of an applicable PUD?
2) For greater clarity, must the PUD occupy all permitted lands or a portion, and should it cover
all permitted lands, can the release apply to just a portion of those permitted lands covered under
a PUD?
Generally, the Division of Reclamation, Mining and Safety (DRMS) will release a site from the
reclamation plan once a demonstration has been made by the operator through the city or county
that a PUD has been filed, reviewed and accepted and that adequate performance warranty has
been filed and accepted. This warranty must be sufficient to complete everything that would be
required to be reclaimed under the DRMS Reclamation Plan. A portion of the permitted area may
be released in this manner.
If you have any question, please do not hesitate to call me at 303-866-3863.
Sincerely,estirif

Reply to OMLR inspection of 20 January 2010.
ATTACHEMENTS:
• Technical Revision Submittal Fee — Check #: 25882 in the Amount of $216.00.
• Proof of Placement — Weld County Clerk to the Board
• Technical Revision — Map
• Revised Seed Mixture
• American West survey of soil stockpile of February 2008

This Technical Revision (TR) is intended to satisfy the concerns expressed in the 20
January 2010 inspection report. Two copies of the TR are included along with the
required fee and proof of placement with the Weld County Clerk to the Board, and
related attachments (see above). As requested in Part 2 of the OMLR inspection report,
included with this submittal is a revised Reclamation Plan Map, since extraction is
essentially complete; except where necessary to effect complete reclamation of the
banks of the completed reservoir, and correlated finished grading, resoiling and other
operations necessary to prepare affected lands for revegetation.
1) The boundary determined by physical survey defines an area of affected land
comprising 154.4± acres, and below the original 160.5± acres permitted. The
difference appears to be based upon differences in measurement from the original
application to the present submittal, which includes measured parcels A (153.5 acres),
B (0.4 acres) and C (0.5 acres). The boundary shown with metes and bounds
description comprises the known permit boundary as we understand it today. Existing
contour information survey is shown, as determined by physical survey.
2) The southeastern reservoir (See area (1) as visible in the NE and SE quadrants of
the map) is a completed basin of approximately 48.9± acres (refer to cyan color
boundary on map — elevation 4830± static water level measured September 2006), that
has met the liner construction and test requirements of the State of Colorado Division of
Water Resources Office of the State Engineer. The approval letter from the Office of
the State Engineer dated 20 June 2003, is included with this submittal.
The Office of Mined Land Reclamation inspection report indicates extraction of the
reservoir has been completed and requires the lands above the static water level to the
perimeter of the surrounding roadway to be resoiled by 28 January 2011. In order to
attend to the erosion attendant to the angle of slope as intersected by wave action
relative to prevailing winds, we believe the erosion can be mitigated by lower this angle
of slopes by flattening those slopes to 5H:1V or flatter. This would entail moving the
perimeter road further back while cutting the existing slopes flatter prior to resoiling.
Subsequent to this work soiling could commence within the stated time, however, since
revegetation should follow, we respectfully request the balance of winter 2011 to
complete this task, or by 20 March 2011, followed no later than 20 May 2011 with
reseeding of the resoiled banks. Since revegetation may take up to three years to fully
express an adequate cover capable of self regeneration, we respectfully request a three
to five year extension for completion of reclamation of the embankments of the
reservoir, or no later than 20 September 2016.
The area requiring resoiling along the reservoir perimeter was determined by estimating
15 linear feet either side of center line (30 foot width total) from elevation 4840 (refer
to dark blue color boundary on map) surrounding the reservoir, or 5,764.0± linear feet,
or a total of 3,202* cu.yds. of soil, and 4.0± acres requiring revegetation.
3) The remaining lands outside of the completed reservoir basin comprise the
balance of affected lands. For purposes of this phase of operations, the areas outside
of the completed reservoir bank area (areas 2, 3, & 4 in the NW and SW quadrants of
the included map) should be considered a separate phase whose period of reclamation
does not commence until the removal of existing stockpiles, finished grading, and
resoiling operations are completed. The point commencing the end of this phase of
operations would occur either by a statement in the required Annual Report to the
Office, or by inspection by the Office at the location consistent with this understanding.
Some lands (area 5) were never disturbed and have an established cover of vegetation,
however, due to the presence of simple annuals, would benefit from more aggressive
weed management. More specifically, these lands occupy those areas south and east
of the green revegetation and resoiling line (D), as visible on the included map. No
other grading, resoiling or seeding efforts are needed here as the lands are essentially
unaffected by past operations.
Varra Companies, Inc. Firestone Pit 112 — M1984-079 2
Technical Revision April 2010
4) The balance of acres will require resoiling or revegetation or both. Specifically,
Area 2 (red-brown hatch in the NW quadrant of the site) is an active area of operations
comprising approximately 12.5± acres, where construction stockpiles and materials
will continue to be used either under agricultural or commercial purposes and will not
be resoiled or revegetated, but be maintained with an adequate cover of road base.
Area 3 (shown in grey-green hatch also in the NW quadrant) comprises 17.0± acres
and will require 13,723± cu.yds. of soil to return a depth of six inches prior to
seeding. The remainder of lands will require some limited grading and complete
seeding for revegetation, and comprise the balance of lands (area 4) lying north and
west of the green resoiling and revegetation line (D), comprising as visible on the
included map.
5) Oil and gas operations are designated within cyan colored envelopes (Areas
A and B) on the included map. These envelopes indicate where existing or future well,
support structures, and related activities may occur. Since the operator remains
responsible for the affected lands, these areas were not subtracted by previously
referenced totals. It is understood that any disturbance by these operations on the
surface are the separate responsibility of the oil and gas operation entities, and any
agreements existing or future with Varra Companies, Inc., or under the several state
and federal laws attending the same, and including any authority under the Colorado
Oil and Gas Conservation Commission (COGCC).
An incident involving contamination of underground waters by Kerr-McGee, was
reported by Kerr-McGee to COGCC on 31 May 2006. The present state of the plume of
contaminated groundwater was determined by CGRS Fort Collins in 2009 and is
reflected in the included map (area C).
6) The estimated route of urban transportation and development will occur
over the balance of lands. As indicated by (E) on the included map, adjacent Firestone
streets (street names may change from how they appear on the existing map) will
eventually course through the developed permit area. Future urban development of the
property for commercial and industrial use is nearly certain, and the location is
presently zoned for commercial and industrial uses by the Town of Firestone.
Once the operator files and a PUD is approved by the Town of Firestone, the operator
will request transfer of the financial warranty to the Town of Firestone and release of
the permit by the OMLR, consistent with Office policy detailed in correspondence from
Carl Mount, Senior Specialist (OMLR) dated 11 April 2008.
7) Summary:
The Soil Stockpile (Area S — in the SW Quadrant of the map) has apx. 22,747.5
cu.yds. as determined by American West's field survey of February 2008. The soil
stockpile has not been utilized since it was measured by American West, and should be
Varra Companies, Inc. Firestone Pit 112 — M1984-079 3
Technical Revision April 2010
more than sufficient to resoil Area 3 and the reservoir perimeter whose combined
replacement requirement to six inches in depth is 16,925* cu.yds. of soil in total
for the areas surrounding the reservoir and for Area 3.
The lands requiring revegetation along the reservoir perimeter and above the green
resoiling and revegetation line (D) is a combined 31.7+ acres in Area 4, plus 17.0±
acres in Area 3, plus 4.0± acres surrounding the reservoir; or a combine area of 52.7*
acres total to be seeded and revegetated with the included revised seed
mixture.

RE: Requirements for site release where the site is subject to a Planned Unit Development
Dear Mr.Janes:
You have requested a determination of what would be required to secure bond release at a site
that is subject to a Planned Unit Development (PUD) issued by a county. Specifically, you posed
two questions in your email that I received the morning of April 9, 2008. These questions were:
1) At what point, and by what evidence, will the Division release a portion, or all, lands from a
Division Permit respective of an applicable PUD?
2) For greater clarity,must the PUD occupy all permitted lands or a portion, and should it cover
all permitted lands, can the release apply to just a portion of those permitted lands covered under
a PUD?
Generally, the Division of Reclamation, Mining and Safety (DRMS) will release a site from the
reclamation plan once a demonstration has been made by the operator through the city or county
that a PUD has been filed, reviewed and accepted and that adequate performance warranty has
been filed and accepted. This warranty must be sufficient to complete everything that would be
required to be reclaimed under the DRMS Reclamation Plan. A portion of the permitted area may
be released in this manner.
If you have any question, please do not hesitate to call me at 303-866-3863.
