1.0 INTRODUCTION
The Olson Pit(DMG Permit M-1980-160)was originally permitted by Frontier
Materials,Inc.,and approved by the Mined Land Reclamation Board of the Colorado
Department of Natural Resources on October 23, 1980.
The original Permit area was 69.39 acres which was divided into three mining
stages with a total mining area of 22.2 acres. The Olson Pit Reclamation Plan called for
the creation of three groundwater-fed ponds corresponding to the three mining stages
with the primary future land use(post-reclamation)indicated to be general agriculture.
On July 15, 1991,the Colorado Mined Land Reclamation Board(MLRB)
approved the Succession of Operators from Frontier Materials, Inc.,to Western Mobile,
Inc.,and in 2002 the MLRB approved the Succession of Operators from Western Mobile,
Inc.,to Lafarge West,Inc. (Lafarge),the current permittee of the"Olson Pit."
On April 7,2003,the Colorado Division of Minerals and Geology(DMG)
approved Lafarge's request for release of 30 acres of the permit area that contained Stage
3 from any further reclamation responsibility. The permit area of M-1980-160 was
therefore reduced to 39.39 acres and contains Stages 1 and 2 of the original Olson Pit
Permit.
The purpose of this Permit Amendment is to revise Permit M-1980-160 as
follows:
First,change the Reclamation Plan for Stage 1 from an open water pond to
uplands and wildlife habitat;
• Second,add 13.35 acres to the currently permitted 39.39 acres for a total area of
52.74 acres;
Third,expand the approved Stage 2 mine area by 10.2 acres from the currently
approved 5.8 acres to 16 acres; and
Fourth,change the post-reclamation land use for Stage 2 from agricultural to
wildlife habitat.
This DMG permit amendment and the supporting documentation were prepared
based on the proposed revisions described above.

5.0 EXHIBIT D—MINING PLAN
5.1 General
The amended mining activities are anticipated to disturb an additional 10.2 acres of
land located in mining Stage 2.
The deposit consists of alluvial sand and gravel overlain by topsoil and overburden.
The topsoil layer and overburden layer will range from 3 to 5 feet in thickness,while the
sand and gravel deposit is 10 to 15 feet thick. The deposit is underlain by shale.The
maximum depth of excavation will be on the order of 20 feet.
The groundwater level lies 2 to 5 feet below natural ground level. The deposit is
therefore classified as a wet alluvial deposit. However,mining operations will be carried out
following dewatering. The sand and gravel deposit is cataloged in the report Sand, Gravel
' and Quarry Resources, Colorado Front Range Counties(Colorado Geologic Survey, 1974).
An estimate of overburden and resource volumes are as follows:
Stage 2
Overburden(yd3) 100,000
Resource(tons) 400,000
5.2 Mining Method
Dry mining techniques will be used. Initially, a dewatering ditch will be excavated
around the perimeter of the active mining area. Groundwater recovered in the dewatering
ditch will be discharged in accordance with Colorado/NPDES discharge permit regulations.
Topsoil and overburden will be placed in temporary stockpiles within the mining area
limits.Topsoil and overburden will be salvaged and stockpiled separately. Topsoil and
{
overburden stockpile areas are shown on the Mine Plan Map.
The deposit will be mined using front-end loaders.Mined material will be transported
by conveyors.All processing of mined materials will be accomplished off-site.
The access road to Stage 2 was previously constructed for access to the"Olson"
property by Frontier Materials, Inc.
5.3 Mining Schedule
Based on an estimated reserve of 400,000 tons,mining will be completed in
approximately 4 months from the start of operations.Mining is currently projected to
commence in 2004.
5.4 Surface Water Management
All mine areas will drain internally.Uncontrolled releases of surface water and
sediment from mining areas will not occur. Stormwater collected in the open pit will be I
managed in accordance with Colorado/NPDES discharge permit requirements. Sediment
generated from localized sormwater runoff and surface drainage will be detained in the
ponds created by the proposed mining operation.
5.5 Disturbance Areas
Disturbance area associated with the proposed permit amendment is as follows:
Disturbance Area Acres
Stage 2 expansion 10
The maximum area that will be disturbed at any point during the operation will be 20
acres.

6.0 EXHIBIT E--RECLAMATION PLAN
6.1 Post-Mining Land Use
The majority of the site is within the 100-year floodplain of Boulder Creek.Weld
County Department of Planning Services considers land located in the 100-year floodplain to
be suitable for agriculture,recreation, and wildlife uses.The post-mining land uses as
proposed in this Reclamation Plan is wildlife habitat. This use is compatible with the
surrounding land uses and with the Weld County planning goals.
Stage 2 reclamation will commence once all mining has been completed in this stage.
Stage 1 mining and reclamation work is ongoing.All reclamation,inchuling regrading and
seeding will be completed in 1 to 3 years following the completion of mining operations.
Note that the original reclamation plan for Stage 1 called for a pond;however,under
the amended reclamation plan the pond has been eliminated.
6.2 Reclamation Measures—Material Handling
Site reclamation measures are illustrated on Exhibit F. Reclamation of Stage 2 will
result in the creation of a 16-17 acre pond.All pit walls will be regarded with stockpiled
overburden. Slopes within 5 feet above to 10 feet below the post-mine water level will be no
steeper than 3H:1 V. Topsoil will be spread over the surface of the regraded slopes in all areas
above the post-mining lake level,and the topsoil-covered surfaces will be revegetated.
Site grading will be performed to create stable topography that will be consistent with
post-closure land uses.Reclamation quantities and costs are summarized in Exhibit L.
6.3 Water
Overburden and mine materials will be inert and impacts to local surface water or
groundwater quality are not anticipated to occur as a result of the development or reclamation
of the proposed expansion area in Stage 2. The applicant will comply with all applicable
State water quality laws and regulations.
6.4 Wildlife
Historically,the area was used for livestock gra7ng. However, some indigenous
wildlife species may be temporarily displaced by the proposed mining activities.Existing
riparian habitat areas will be undisturbed by the operation.
6.5 Topsoiling
Topsoils in the proposed mine areas are predominantly aquolls,aquents and sandy
loam. These soils will be stripped and stockpiled during overburden removal,and retained
for replacement during site reclamation.At reclamation,topsoil will be spread over areas to
be reclaimed.
Topsoil stockpiles will be protected from erosion and other damage by best
management practices. Soil amendments are not expected to be required due to the nature of
the soils.However,topsoil samples will be subjected to agricultural testing prior to
reclamation to assess fertilizer requirements. SCS soil fertilizer recommendations,if any,will
be followed.
6.6 Revegetation -
Following topsoil replacement,reseeding will be performed according to SCS
recommended practices.Based on SCS guidance for other local projects having similar
surficial soils,the following revegetation procedures are anticipated:
• Grass seed will typically be planted in unfrozen soil between October 1 and April
30.
• Grass seed will be planted with a grass drill or,where necessary,with a broadcast
seeder.
• The proposed seed mix and application rates in pounds of pure live seed per acre
are described on the following pages.
• If necessary, critical areas may be covered with straw or hay mulch to control
erosion during germination.
• Weed-control practices will be implemented as required.
The above procedures may be modified as conditions dictate.
In areas that are peripheral to the post-mining lake,marsh and aquatic plants will
establish themselves.The species of plants anticipated to naturally occur along the lake
shoreline include cattails,willows,cottonwoods, and various rushes.These plants should
minimize shore erosion potential.
6.7 Buildings and Structures
No buildings will be constructed during the operation,as processing and .
administrative functions will be carried out in existing structures located off-site.Only
mobile equipment will be used in the mine area. The overland conveyor system required for
•
transport of sand and gravel is portable.

8.1 General
Mining at the Olson Pit will intercept shallow groundwater,which lies from 2 to 5
feet below the current ground level. Deeper bedrock aquifers that underlie the site will be
unaffected by the mining operation because of the shallow depth of excavation.
Upon completion of mining,one 16-17 acre pond will be created for wildlife habitat.
Local surface water ponds,ditches,water courses, and tributaries are shown h wn on the
pre-mining map. The nearest water course is Boulder Creek.No impact to Boulder Creek is
expected as a result of mining.
8.2 Potential Water Resource Impacts
• The Olson Pit sand and gravel operation will have minimal impacts on the water
resources in the area.The nearest domestic wells are part of the St.Vrain and Left-Hand
water service area. Similar wells in the area are closer in proximity to other existing sand and
gravel mining activities and are therefore not likely to be impacted by Olson Pit mining
operations.
8.3 Discharge Permits
Like Stages 1 and 3, Stage 2 of the Olson pit will be dewatered and operated as a dry
mine.Alluvial groundwater from pit dewatering will be discharged into either Boulder or
Idaho Creek. The applicant has a Colorado/NPDES discharge permits for the Olson Pit and
-
will discharge in accordance with permit conditions.
8.4 Surface Water Management
A surface water management plan is in effect for the currently permitted operations
this plan will be updated to incorporate the Olson Pit.

' THIS AGREEMENT is made this ,2, day of , 1980, between
Lee Ervin Olson and Florence M. Olson, hereinafter to ed OLSONS, and THE WATER
USERS ASSOCIATION OF DISTRICT ND. 6, a Colorado nonprofit corporation, herein-
after termed WATER USERS:
WITNESSETH:
WHEREAS, OLSONS own the property described ..n the attached Exhibit A
for which Frontier Materials has applied for a Special Use Permit from Weld
County and for a Mining Permit from the Mined Land Reclamation Board of the State
of Colorado to enable it to conduct sand and gravel mining activities on the
property; and
WHEREAS, OLSONS shall be responsible for maintenance of the reclama-
tion plans as completed by Frontier Materials, Inc., which plans include the
creation of one or more lakes; and
WHEREAS, the WATER USERS have no objection to the mining and reclama-
tion plans if an augmentation plan for Boulder Creek is entered-into for the pur-
pose of compensating for potential additional evaporation which may result from
the lakes created by the mining, and the parties have agreed upon such an augmen-
tation
plan as set forth herein.
NOW, THEREFORE, it is mutually agreed as follows:
I. OLSONS Agree as follows:
A. To allow Frontier Materials, Inc. to conduct a mining operation
in accordance with the requirements set forth in the Mining and Recla-
mation Plan as finally approved by Weld County and the Mined Land
Reclamation Board of the State of Colorado as per a separate agree-
ment on OLSONS land; -
B. That neither they nor their successors nor assigns will
claim, or attempt in any way to appropriate any water which is
assertedly developed, or which assertedly augments stream flow,
as a result of the contemplated mining operation and reclamation
plan. The foregoing sentence shall not preclude OLSONS from
[_ raising any such claim as a defense to any judicial or administra-
tive proceeding brought by either a governmental agency or a water
jj user not bound hereby, so long as the water which OLSONS assert
jt has been so developed or so augments the streamflow is not claimed
to exceed that necessary to compensate for the injury to the

manner, and in a manner that will have inlet and outlet structures which
can be controlled by the State Engineer of the State of Colorado and his
representatives.
D. Frontier Materials, Inc. will reconstruct historical wasteways
and ditches in such a manner as to assure that no ditch user or person
affected by such ditch or ditches shall be injured and in such a manner
that the water and wastewater flowing in such ditches will flow in the
same manner and at the same time as it has historically flowed. In
addition, written approval from the owners of each ditch affected
by the mining activities shall be received, and copies furnished
to the WATER USERS prior to the commencement of mining activities.
E. To reimburse the WATER USERS for its necessary and reason-
able expenses incurred in connection with its review of the Mining
and Reclamation Plan and the preparation of this Agreement, which
the parties agree is $500.00
F. OLSONS, for themselves, their successors and assigns, fur-
ther 'agree to augment Boulder Creek, thereby preventing injury to
other water users, by allowing all water attributable to their entire
1/10th ownership in the Carr and Tyler Ditch and one-half share of
the common capital stock of the Godding Dailey and Plumb, not to
be diverted through the ditch headgates, thereby allowing such
water to remain a part of the water of Boulder Creek, or if diverted
at the ditch headgates, not to be used for irrigation or any other
purpose, but to be allowed to flow back into Boulder Creek. The
decision as to whether or not such water shall be diverted at the
respective ditch headgates, and if diverted, at which point it shall
be allowed to flow back into Boulder Creek, shall be made by the
WATER USERS. In any case, this water shall be used to augment
evaporation from the lake resulting from OLSONS mining and reclama-
tion plans and shall never be used for any other purpose. The
land heretofore irrigated by, and the water heretofore attributable
to, such shares shall no longer be irrigated by such shares.
G. In order to implement the provisions of this Agreement,
OLSONS agree that the Certificates described in the preceeding para-
graph shall be endorsed as follows:
"These shares and the uses of water a tributable thereto
are restricted by an Agreement dated /96'0 ,

The subject site area has a high plains, continental climate. With the mountains to the
west,variations in temperature are wide. The average annual temperature is lower than in the
high plains, and the temperature increases from east to west in the plains area.Average
annual precipitation also increases from east to west. In the high plains area,rainfall is light
and humidity is low.
Differences in altitude and exposure create great variations in both temperature and
precipitation. In general,temperatures are cooler at higher elevations,and northern exposures
are cooler than southern exposures. The average frost-free period ranges from 225 to 270
days.Annual precipitation ranges from abut 13 to 24 inches and increases with elevation. i
In the eastern high plains area,the climate is modified considerably from that
expected of a typical high plains because of the nearby mountains to the west. The winds
characteristic of the plains are reduced somewhat by the shielding effect of the mountains.
