1. Reclamation Plan
a. Water Storage Reservoir: Reclaimed shoreline slopes will be no steeper than 3:1.
b. Topsoil: All suitable soil material will be salvaged for topsoil replacement. Topsoil
will be used to reclaim the site. The topsoil will be segregated and stored separately
from the overburden material as required by Rule 3.1.9(1). Berms will be protected
from wind and water erosion by vegetative cover if in place more than one year.
Topsoil samples will be subjected to agricultural testing prior to reclamation to assess
fertilizer requirements. More information is provided in the DMG permit.
c. Re-vegetation: Recommendations have been incorporated into all existing
reclamation plans. The Soil Conservation Services (SCS) and/or the Adams County
Cooperative Extension will be contacted periodically throughout reclamation for
assistance with weed control. Detailed re-vegetation information, as well as seed-mix
information for upland and marsh areas, and for pond areas can be found in the Use-
by-Special Review plans.
2. Surface and subsurface water
a. Lafarge has been working to address all surface and sub-surface water issues as part
of their DMG application. As a condition of their DMG permit, Lafarge is required to
maintain the historic hydrologic balance. Lafarge has developed a comprehensive
groundwater monitoring and mitigation plan which has been submitted to the DMG
and is currently being finalized.
NEIGHBORING COMMUNITIES
1. City of Fort Lupton
a. Lafarge has presented their Riverbend application before the Planning Commission
and City Council at various points in the planning process. As a significant portion of
the property is located with the City of Fort Lupton's Urban Growth Boundary,
Lafarge is committed to working with City Staff and Officials to ensure minimal
impacts to the residents of Fort Lupton. To that end, Lafarge will:
• Install a vegetated berm on the south and east sides of the plant side area to shield
these operations from surrounding landowners and traffic on U.S. Highway 85.
The existing cottonwood gallery to the west and north of the plant site should act
as sufficient buffer to landowners located west of the site.
TETRA TECH RMC Ms. Jacqueline Hatch
November 1, 2005

• Use WCR 6 as the primary site access. The existing approved designated haul
route specifies that truck traffic must exit the site heading east on WCR 6 to U.S.
Highway 85. Weld County Public Works, CDOT, Aggregate Industries and
Lafarge collaborated on the improvements to the WCR 6 and U.S. Highway 85
interchange. These improvements were based on increased traffic projections for
this intersection caused by the two mining operations.
2. City of Brighton
a. Primary trail: The primary trail location is shown as "potential"based on the mine
life, which exceeds 35 years. Once reclamation is complete, Lafarge will
coordinate with the appropriate jurisdictions to develop the primary trail
alignment. To the extent that the primary trail location extends across properties
owned by Lafarge, Lafarge can and will provide the primary trail once
reclamation is complete. However, a number of the properties are not owned by
Lafarge and the future primary trail alignment will need to be negotiated with the
individual landowners.
b. Trail timing: None of the proposed trails will be constructed or opened to the
public until after reclamation of the Riverbend site is complete, as required by
MSHA regulations.
c. Potential trails: All trail alignments are shown as "potential"based on the
projected life of the project, which is anticipated to exceed 35 years. Once
reclamation is complete, Lafarge is committed to coordinating with the
appropriate jurisdictions and landowners to develop the trail network shown in the
Final Landscape and Reclamation Plan.

MEMORANDUM
TO: Eric Reckentine
FROM: Sarah Foster, Project Engineer
RE: Riverbend Neighborhood Meeting
DATE/TIME: 9/12/05; 7PM
PLACE: Ft. Lupton Recreation Center
DATE: 9/13/05
Summary of the Riverbend Neighborhood Meeting
Mr. Eric Reckentine of Lafarge, Inc. welcomed attendees and began the meeting by introducing
key members of the development team. He went on to give background information about
Lafarge North America and local awards Lafarge has been honored with. Mr. Reckentine then
reviewed for those individuals present the future plans for the collective Riverbend properties, as
well as a brief overview of reclamation characteristics. He continued with explanations of the
site boundaries, mining areas, existing permit information, plant site characteristics, conveyance
of materials within the mine site, as well as floodplain and ditch information. Some members of
the audience were vocal and paused Mr. Reckentine several times to ask questions or express
concerns (summarized below). Mr. Reckentine then passed the microphone to Ms. Jennifer
Vecchi (Vecchi and Associates) to explain the reclamation plan.
Ms. Vecchi detailed components of the reclamation plan to include: silt basin wetlands, lined and
unlined ponds for water storage, creation of wildlife habitat and new vegetation, opportunities
for future development and/or civic use of the land, potential for trails and open space, and the
reclamation plan's relationship to county and local future development plans. Ms. Vecchi
utilized conceptual graphics and posters to illustrate the potential future of the site.
When the presentation was concluded questions from the audience were addressed. Following is
a summary of the questions and concerns:
Q: What will the traffic impacts on CR 6 be? How many trucks? Was CR 6 chosen because it
has a traffic signal?
A: There will be approximately 500 trucks per day working 10 hour shifts. CR 6 was chosen as
part of a collaborative process between multiple agencies (Lafarge, Aggregate Industries,
Asphalt Specialties, Weld County, and CDOT) in order to develop an improvement plan for CR
6. Lafarge will comply with this plan.
Q: How will the conveyor cross CR 8?
A: Over the road.
H:\4137_012_01\Neighborhood Meeting\R iverbend_NeighborhoodMeeting091205_memo.doc
Q: What will happen to the Bald Eagles and their habitat?
A: Mining will be restricted certain times of the year so as to not interrupt their natural cycles.
Specifically, the plant site will give the nesting grounds a '/ mile buffer where no mine operation
will occur during the roosting/nesting period.
Q: Does Lafarge own any shares of Brighton and/or Brantner Ditch water? If yes, what does
Lafarge plan to do with the water?
A: Lafarge owns three shares of Brighton, although only 1 % is currently recorded. They plan to
use the shares to augment evaporative losses.
Q: Who is responsible for long-term augmentation of unlined reservoirs?
A: The landowner.
Q: Will there be any impact to the water table in Wattenburg? What effect, if any, will occur on
the East side of the S. Platte River?
A: There should be no drawdown over 1000' of the site. The S. Platte should limit drawdown to
the east, but if the monitoring wells show drawdown then it will be handled the same as for the
properties to the west per DMG& SEC, regulations/requirements. Lafarge has developed a
groundwater monitoring and mitigation plan, which is being reviewed by the State of Colorado
Division of Minerals and Geology (DMG).
Q: When does Lafarge plan to break ground on CR6?
A: Approximately 10 years.
Q: What will be the first activities Lafarge undertakes?
A: Lafarge will first work on the plant site (map shown during meeting), and begin planting
vegetation and developing the berm.
Q: What kind/type of fencing will Lafarge use on site?
A: 6' fencing is what Lafarge commonly uses.
Q: How will impacts on bordering property be handled [affecting wetlands and/or wells]?
A: There are mitigation plans in the works, as well as many monitoring wells strategically
placed throughout the site that will allow Lafarge to be aware of any degradation of adjacent
areas that may occur. He indicated that they will indemnify any affected parties should
drawdown below allowed limits occur.
Q: Will Lafarge indemnify anyone with a pond or well that may be affected? If yes, what
remedies are being considered?
A: There are mitigation plans in the works, as well as many monitoring wells strategically
placed throughout the site that will allow Lafarge to be aware of any degradation of adjacent
areas that may occur. He indicated that they will indemnify any affected parties should
drawdown below allowed limits occur.
H:\4 137_012_01\Neighborhood Meeting\Riverbend_NeighborhoodMeeling091205_memo.doc
Q: Will retention basins be sealed, and if yes/no how was the decision made to seal or not seal?
If no, who will augment for evaporation?
A: Riverbend is going to be a dry-mining site. After mining, some of the retention basins will be
sealed with a compacted clay liner, and others will not, dependent upon the agreement and/or
wishes of the individual property owners.
Q: What will be done to prevent flooding?
A: There are no plans for changes to the floodplain.
Q: Will slurry walls be used? If slurry walls won't be used, what is the reason?
A: Slurry walls will not be utilized, but some water bodies will be lined. The selection was based
upon contract obligations/agreements and desires of the individual property owners.
Q: Will access on both sides of ditch remain open near Lupton Bottom?
A: Should not change from current access.
Q: How close to the river can Lafarge mine?
A: 400' unless there is a bank stabilization plan, then 200'.
Q: Will access on both sides of ditch remain open through Norden?
A: Should not change from current access.
Q: Who owns Lafarge?
A: Lafarge is French-owned.
Q: Where is Lafarge currently mining?
A: Off Old Brighton Rd. in Adams County.
Q: What steps does Lafarge still have to take before start on CR6?
A: The application to Weld County has been submitted, and it is anticipated that it will go
before the Planning Commission in November, 2005, and to the County Commissioners the
following month; and the DMG permit application has been filed and it is anticipated that
approvals will be received by year end (2005).
Comment: Property owner of adjacent landlocked property wanted to know how access to his
property will be handled.
A: In the case of the landlocked property, the individual was referred to meet with Mr.
Reckentine to make arrangements for access.

RE: Letter Agreement—Lafarge West, Inc. (Lafarge) Riverbend Operation 112c
Permit Amendment 01, Permit No. M-2000-016; AMUSR - 1259
Dear Mr. Wright:
This letter Agreement pertains to the Lafarge Riverbend Operation, as amended, and its potential
effect on the Brighton Ditch Company Ditch and associated facilities. The proposed sand and
gravel mine site is located in Weld County, Colorado. A vicinity map and the legal description
of the amended site boundary are attached. The Brighton Ditch traverses the property along its
west edge. This Agreement describes commitments made to Brighton Ditch Company by
Lafarge, related to its operations on the entire Riverbend Project.
The ditch will not be disturbed by the proposed mining plan. Mining and reclamation of the pits
will remain at least 200 feet from the ditch and headgate structure unless approved by the Ditch
Company, subsequent to review of plans and specifications by the Ditch Company's engineer.
Lafarge makes the following additional commitments to ensure the reasonable operation of the
Brighton Ditch.
1. No dewatering flows will be added to the ditch during mining operations unless there is
an agreement in place with the Ditch Company. This will require that plans and
specifications be reviewed and approved by the Ditch Company's engineer prior to
completion of a subsequent agreement.
2. To control seepage into the pits located on the west side of the South Platte River, pit
areas adjacent to the Brighton Ditch will be backfilled to create 3H:1 V slopes as soon as
practicable after mining near the ditch is complete. The backlit] adjacent to the ditch will
contain compacted material similar to pit liners constructed for water storage reservoirs
(as presented in the Riverbend Operation Regular 112c Reclamation Permit).
Alternatively, a setback distance equal to twice the pit depth will be maintained from the
bank or edge of the ditch to the crest of the pit excavation. In addition, Lafarge will add
monitoring devices to effectively assess and mitigate losses to the ditch due to seepage
from dewatering activities, including measuring weirs and continuous recorders as
approved by the Ditch Company's engineer. The monitoring devices will stay in place

for a sufficient period after reclamation to effectively establish that there is no damage
from seepage to the ditch.
3. Prior to the start of mining and during the mining operations, Lafarge agrees to allow
access across the property for Brighton Ditch Company personnel or their representatives
to perform ditch maintenance and operation activities. Brighton Ditch Company will be
responsible for any fence repairs, other property damage, or personal injury related to or
arising from their operations on the Riverbend property as amended.
4. During mining and reclamation activities, which are estimated to take approximately 30-
35 years to complete, roads will be available and access will be allowed for the
maintenance and operation of the ditch. Lafarge further acknowledges the ditch
company's historic non-exclusive easement and all existing rights associated with the
ditch. Lafarge will be responsible for maintaining ingress and egress to the ditch and will
not place stockpiles or equipment within the easement that could block access for the
Ditch Company without written notification and approval of the Ditch Company.
5. The course of the South Platte within the permit boundary will not be changed due to
mining or reclamation activities.
6. Consistent with permitting requirements, Lafarge agrees to provide compensation for any
unforeseen damage to the Brighton Ditch or associated structures caused by mining
activities. However, prior to commencing mining, Lafarge will work with representatives
of the Brighton Ditch Company to specifically address the details needed to insure that
the ditch and appurtenant structures are protected.
7. Lafarge has the authority to represent the landowners within the Riverbend permit
boundary per their respective lease agreements for mining, permitting and reclamation of
their property. See attachment for copy of lease agreement.
8. Lafarge agrees to pay for the Ditch Company's legal and engineering fees associated with
this permit application and for fees related to future agreements.
9. Operator agrees that if by reason of its construction, operation or mining of said gravel pit
any damage, increased seepage or break in or to the Brighton Ditch occurs, Operator will
with all due diligence, repair and replace such property of The Brighton Ditch Company
in substantially the same condition as the same was in prior to such a break, increased
seepage or damage and will pay any and all monetary damages resulting from such break,
increased seepage or damage sustained or incurred by The Brighton Ditch Company or
its stockholders or water users.

RE: Letter Agreement - Lafarge West, Inc. (Lafarge) Riverbend Operation 112c Permit
Amendment 01, Permit No. M-2000-016; AMUSR- 1259
Dear Mr. Wagner:
This letter Agreement pertains to the Lafarge Riverbend Operation, as amended, and its potential
effect on the Lupton Bottom Ditch and associated facilities. The proposed sand and gravel mine
site is located in Weld County, Colorado. A vicinity map and the legal description of the
amended site boundary are attached. The property includes a portion of the South Platte River
and a headgate for the Lupton Bottom Ditch. The headgate and the ditch are located within the
Riverbend Project boundary. This Agreement describes commitments made to Lupton Bottom
Ditch Company by Lafarge, related to its operations on the entire Riverbend Project.
The headgate structure and the ditch will not be disturbed by the proposed mining plan. Mining
and reclamation of the pits will remain at least 200 feet from the ditch and headgate structure,
unless approved by the Ditch Company, subsequent to review of the plans and specifications by
the Ditch Company's engineer. This is consistent with the currently permitted and approved
Colorado Division of Minerals & Geology (DMG) mining and reclamation plan and the Weld
County zoning resolutions for the Riverbend project. Lafarge makes the following additional
commitments to ensure the reasonable operation of the Lupton Bottom Ditch.
I. No dewatering flows will be added to the ditch during mining operations unless there is a
written agreement in place with the Ditch Company. This will require that plans and
specifications be reviewed and approved by the Ditch Company's engineer prior to
completion of a subsequent agreement.
2. To control seepage into the pits located on the west side of the South Platte River, pit
areas adjacent to the Lupton Bottom Ditch will be backfilled to create 3H:I V slopes as
soon as practicable after mining near the ditch is complete. The backfill adjacent to the
ditch will contain compacted material similar to pit liners constructed for water storage
reservoirs (as presented in the Riverbend Operation Regular 112c Reclamation Permit).
Alternatively, a setback distance equal to twice the pit depth will be maintained from the
bank or edge of the ditch to the crest of the pit excavation. In addition, Lafarge will add

monitoring devices to effectively assess and mitigate losses to the ditch due to seepage
from dewatering activities, including measuring weirs and continuous recorders as
approved by the Ditch Company's engineer. The monitoring devices will stay in place
for a sufficient period after reclamation to effectively establish that there is no damage
from seepage to the ditch.
3. Prior to the start of mining and during the mining operations, Lafarge agrees to allow
access across the property for Lupton Bottom Ditch personnel or their representatives to
perform ditch/headgate maintenance and operation activities. Lafarge understands these
activities may include reinforcing, by placing concrete-rubble armoring, the south bank
of the South Platte River on his property from time to time. Lafarge will use reasonable
efforts to obtain any necessary cooperation of Donald L. Rittenhouse,the owner of the
southernmost property, within the permit area. Lupton Bottom Ditch will be responsible
for any fence repairs, other property damage, or personal injury related to or arising from
their operations on the Riverbend property as amended.
4. During mining and reclamation activities, which are estimated to take approximately 30-
35 years to complete, roads will be available and access will be allowed for the
maintenance and operation of the ditch. Lafarge further acknowledges the Ditch
Company's historic non-exclusive easement and all existing rights associated with the
ditch.
5. The course of the South Platte within the permit boundary will not be changed due to
mining or reclamation activities. The South Platte River bank adjacent to the mining
operation north of Weld County Road 6 features significant existing concrete-rubble
armoring to stabilize the main channel alignment. The effectiveness of the existing
concrete rubble will be measured, monitored, and evaluated for channel stabilization. If
necessary, Lafarge Corporation will provide additional stabilization within the permit
boundary. However, outside the permit boundary, Lafarge Corporation cannot guarantee
the stability of the riverbank or the main channel alignment and will not be responsible
for its maintenance outside of the permit boundary.
6. Consistent with permitting requirements, Lafarge agrees to provide compensation for any
unforeseen damage to the Lupton Bottom Ditch or associated structures, as well as
secondary damages such as water replacement loss or crop damage related to water loss,
caused by mining activities. However, prior to commencing mining, Lafarge will work
with representatives of the Lupton Bottom Ditch Company to specifically address the
details needed to insure that the ditch and appurtenant structures are protected. If
however, a dispute arises over damages,then both parties agree to initially have an
unbiased, third party arbitrator, attempt to negotiate the dispute.
7. Lafarge has the authority to represent the landowners within the Riverbend permit
boundary per their respective lease agreements for mining, permitting and reclamation of
their property. See attachment for copies of lease agreements.

Attachment A
Lafarge North America — Riverbend Mine
Groundwater Monitoring and Mitigation Plan
PURPOSE
This Plan is prepared for incorporation into the Colorado Division of Minerals and Geology
(DMG) permit. Lafarge North America(Lafarge) has submitted a Temporary Substitute Water
Supply Plan to the State Engineer's Office for approval. The temporary substitute supply plan
protects senior vested water rights and mitigates depletions of flows in the South Platte River.
This Groundwater Monitoring and Mitigation Plan presents the methods for monitoring of
groundwater during mining and reclamation, and for mitigating groundwater impacts to wells
and trees due to mining at the Riverbend Mine in Weld County, Colorado.
BACKGROUND
The Riverbend Mine site is in Weld County, Colorado, southwest of the Town of Fort Lupton.
The site occupies approximately 1370 acres in portions of Sections 7, 18 and 19 of Township 1
North, Range 66 West and portions of Sections 12, 13 and 24 of Township 1 North, Range 67
West all of the 6th Principal Meridian. The South Platte River flows generally along the east side
of the site. The Lupton Bottom Ditch(an irrigation ditch) flows through the site. The extraction
of sand and gravel will be the"dry" mining method. That is, mine cells will be dewatered to
facilitate extraction of the gravel. The reclamation plan of the mine includes unlined cells and
lined cells for water storage.
Dewatering of the mine cells will lower the groundwater in the surrounding alluvial aquifer.
This will be a temporary impact that will cease after the dewatering phase. The lowering of the
groundwater levels may impact nearby wells and trees.
Historic Use
The site has been managed primarily for irrigated and non-irrigated agriculture using small
ditches and laterals. There are existing and proposed gravel mining operations north and south
of the site. There are also a few rural residences near the site.
Monitoring Well Installation
Thirty monitoring wells have been installed at the site and a water level monitoring program
began in May 2004. The wells were installed outside the limits of mining so that groundwater
can be monitored during and after mining. Locations of the wells are shown in Figure 1.
Additional monitoring wells will be installed as requested by the DMG in their Adequacy
Review No. 6 dated September 1, 2005.

Lafarge West,Inc.Riverbend - 1 - October 2005
Groundwater Monitoring and Mitigation Plan H\4137_012_02\Groundwata\Riverbend GW Mon&Mitigation Plan 8-26-0s.doc
The objectives of the well installation and monitoring program are to monitor the current
groundwater conditions and to provide a basis for assessing the future impacts of the proposed
mining on nearby wells and trees. Through the well monitoring program, pre-mining
groundwater elevations, flow patterns across and near the property, and seasonal fluctuations are
being documented.
The additional wells requested by the DMG will be installed in phases consistent with the mining
phases. The wells will be installed 18 months prior to the start of mining to allow the collection
of five quarters of monitoring data.
Well Inventory
A well inventory (AMEC 2005) of the site and adjacent areas was conducted to identify wells
near the project. The inventory involved review of well records (Registered Wells) on file with
the Colorado Department of Natural Resources, Office of the State Engineer(SEO).
The search area of the well inventory was 1,500 feet from the property boundary. As required by
the SEO, Lafarge will attempt to get a 600-foot well spacing agreement statement from the well
owners who have wells within 600 feet at least six months prior to the commencement of mining
of a relevant phase. The well inventory identified a total of 13 wells within 600 feet of the site
boundary. Lafarge either owns or has a lease agreement with 9 of the 13 wells. Consequently,
only four wells will require the 600-foot well spacing agreement and/or mitigation measures.
Prior to mining, Lafarge will field check the location of wells, registered and unregistered, and
document the location, ownership and contact information for the wells.
Modeling
During 2005, a numerical groundwater flow model was constructed of the site and surrounding
areas to assess the potential impacts that the mine operation may have on groundwater levels
(AMEC 2005). The U.S. Geological Survey's groundwater code MODFLOW(McDonald and
Harbaugh, 1988) was used for the modeling.
The groundwater investigation and modeling of the site concluded that the water table occurs at
depths of approximately five to ten feet below ground surface during the irrigation season. The
thickness of saturated alluvial sediments ranges from approximately 20 to 40 feet. The typical
groundwater flow direction is to the north along the South Platte River, but directions and
gradients vary locally and seasonally due to changing irrigation patterns and pumping of
irrigation wells.
MONITORING AND MANAGEMENT
Mining Plan
The Mining Plan has been designed to reduce groundwater impacts to adjacent properties to the
greatest practical extent. The extraction cells will be dewatered with each phase of mining.
Lafarge proposes to construct recharge basins along the boundaries of: Cell 1 Plant Area, Cell 1
Phase 4, Cell 1 Phase 2, Cell 1 Phase 3, Cell 1 Phase 5, Cell 1 Phase 6 to maintain pre-mine
Lafarge West,Inc.Riverbend - 2 - October 2005
Groundwater Monitoring and Mitigation Plan H\4137 012 02\Groundwater\Riverbend GW Mon&Mitigation Plan 8-26-05.doc
water levels beneath the trees near these cells(see Figure 1 for locations of recharge basins).
Pre-mine groundwater levels will be evaluated through groundwater monitoring.
Groundwater Monitoring
Thirty monitoring wells (AMEC 2005)have been installed at, and adjacent to, the site. Water
level monitoring in the 30 wells will be conducted on a monthly basis for five quarters prior to
mining to establish a site-wide baseline. Once mining begins, monitoring will be conducted on a
monthly basis until a steady state condition is reached (during dewatering), and on a quarterly
basis thereafter until two years after the mining in a particular phase ends. Each mining phase
will be evaluated on a case-by-case basis to determine if a less frequent monitoring schedule is
appropriate. If this is found to be the case,then Lafarge will submit a Technical Revision
request to the Division of Minerals and Geology to relax the groundwater monitoring
requirements in those certain areas. Table 1 presents the wells associated with each mine phase.
Reporting
Prior to mining, Lafarge will prepare and submit a report on baseline groundwater levels,
utilizing data from the 30 existing wells. Thereafter, groundwater monitoring data will be
submitted with the annual progress report to the DMG and copied to Weld County Planning and
Engineering Departments. At least five quarters of monitoring data will be obtained prior to
mining each phase. If any of the following trigger points are reached:
• A complaint from a well owner within 1,500 feet of the site boundary,
• The relative seasonal groundwater level at any of the domestic wells or monitoring wells
adjacent to domestic wells differs from the baseline conditions by more than two feet,
• Or the qualified individual inspecting adjacent off-site vegetation denotes stressed
vegetation,
then Lafarge will submit their groundwater monitoring data to the DMG immediately. Copies
will also be provided to Weld County Planning and Engineering Departments.
Wells Within 600 Feet
Owners of all water supply wells within 600 feet of extraction cells will be contacted and asked
to sign a 600-Foot Well Spacing Statement. If the owners indicate that the wells are in use,
Lafarge will attempt to measure well depth, pumping rate, pumping water level, and non-
pumping water level prior to mining. If well owners are unwilling to allow Lafarge access to
their wells to gather the necessary measurements,then Lafarge will install a monitoring well
between the well and the mine. Additionally,to establish a baseline, Lafarge will attempt to
measure water levels in these wells monthly prior to mining. After mining begins, Lafarge will
attempt to measure water levels in the existing water supply wells quarterly, until two years after
mining.
MITIGATION
Monitoring data will be used to identify potential changes in alluvial groundwater flow or
elevation associated with mining and reclamation activities. Baseline data collected from the
Lafarge West,Inc.Riverbend - 3 - October 2005
Groundwater Monitoring and Mitigation Plan H\4137_012_02\Groundwateiterbend GW Mon&Mitigation Plan 6-26-05 doc
monitoring program will provide a range of relative water levels associated with pre-mining
groundwater conditions. Experience at other sand and gravel mine sites in similar geologic
settings has found that groundwater levels tend to fluctuate between two to four feet each year,
being highest in the summer and lowest in the winter and early spring.
WELLS
• If, during mining, the relative seasonal groundwater elevation at any of the domestic
wells or monitoring wells adjacent to domestic wells differs from the baseline conditions
by more than two feet, and the condition was not observed during baseline monitoring, or
if Lafarge receives a complaint from any well owner within 1,500 feet from the site
boundary, then Lafarge will evaluate the cause,or take action within 7 days as indicated
below,and notify the DMG.
• If a well goes dry, Lafarge will implement mitigation measures within 7 days. Mitigation
measures would include providing a temporary alternative water supply that meets the
documented historic well production, or need, until further investigation can be
conducted to determine if the well condition is due to the mining operation. Historic
production will be documented as outlined in the above section `Wells Within 600 Feet'.
• After the DMG has been notified, Lafarge will review the available data and information
and submit a report to the DMG within 30 days. The evaluation will include discussions
with any well owner who has contacted Lafarge regarding a concern and review of
baseline data from the well and vicinity to evaluate whether changes may be due to
seasonal variations, climate, mining, or other factors. The report will identify the extent
of potential or actual impacts associated with the changes. If the extent of groundwater
changes due to mining or reclamation activities is determined to be a significant
contributing factor that has, or may create adverse impacts, the mining associated impacts
will be addressed to the satisfaction of the DMG.
• If, after review, the Division of Minerals and Geology determines that the impact on a
well, for which temporary mitigation has been initiated, is not a result of Lafarge's
activities, or is not solely a result of Lafarge's activities, then Lafarge shall reduce or
cease mitigation accordingly with the approval of the DMG.
• Lafarge will begin to implement one or more mitigation measures if mining and
reclamation activity is determined to be a significant contributing factor to groundwater
changes requiring mitigation. Lafarge has no responsibility to provide mitigation for
wells that are constructed after the permit is approved.
• Mitigation measures,divided into temporary and long term,may include, but are not
limited to:
Temporary:
Compensation for well owner to use their existing treated water system to replace
the well production loss;
Lafarge West,Inc.Riverbend - 4 - October 2005
Groundwater Monitoring and Mitigation Plan H:\4137_012_02 N GroundwaterVliverbend GW Mon&Mitigation Plan 8-26-05.doc
- Provide a water tank and deliver water as necessary to meet documented historic
well production or need;
- Other means acceptable to both the well owner and Lafarge.
Long-Term:
- Cleaning a well to improve efficiency.
- Providing an alternative source of water or purchasing additional water to support
historic well use in terms of water quantity and quality. If needed, water quality
parameters will be checked in affected wells to ensure alternative sources support
the historic use.
- Modifying a well to operate under lower groundwater conditions. This could
include deepening existing wells or lowering the pumps. All work would be done
at Lafarge's expense with the exception of replacing equipment that was non-
functional prior to mining.
- If existing wells cannot be retrofitted or repaired: replacing the impacted well
with a new well.
- Providing flood irrigation to address concerns over impacts to sub-irrigated lands
adjacent to the site.
• If a groundwater mitigation action is required, Lafarge will notify the Weld County
Engineer and the DMG of the condition, action taken, and result.
TREES AND WETLANDS
Two years prior to mining, Lafarge will hire a qualified expert to inventory the off-site
vegetation. Lafarge will attempt to obtain access agreements from adjacent landowners to install
shallow wells in the cottonwood galleries and identified wetlands. Impacts to trees will be
mitigated through monitoring and if necessary, managed recharge of the alluvial aquifer or
watering of the trees. The frequency of monitoring will be as described above. If the water level
data indicates that the water table beneath the trees declines by more than one foot of the pre-
mine water levels during the growing season, or the trees show signs of stress, Lafarge will
commence mitigation measures within 10 days of the determination of impacts. Lafarge will
hire a qualified expert to perform regular inspections of offsite vegetation. The inspection
frequency will be twice per year, once in the spring and once in the summer. The mitigation
measures would be by one of two methods:
1) Watering of the wetlands or trees using dewatering water, or
2) Managed recharge of the alluvial aquifers. The managed recharge would be
accomplished using basins positioned between the mine cells and the wetlands or
trees. The basins would be filled with dewatering water. The basins would
extend along the perimeter of the mine cell between the cell and the trees. The
basins would be excavated to the top of the gravel (about 5-8 feet) with side
slopes of 2:1 (horizontal:vertical). The bottom width would be about 4-8 feet.

FROM: Jennifer E. Vecchi, AICP
RE: Riverbend Use By Special eview Application
DATE: March 28, 2006
Attached please find revised maps for the Riverbend Use By Special Review Application. As you
may recall from your previous review of this application, Riverbend is a proposed mineral resource
development facility including a concrete and asphalt batch plant, concrete casting facility, recycling
plant, materials blending, import of materials and gravel mining. The site is located in Weld County
south of State Highway 52, east of Weld County Road 23, north of Weld County Road 6, and west of
State Highway 85. Since you last reviewed the application, some changes have been made to the
application that we wanted to bring to your attention for review prior to the Public Hearing on this
application. The changes are outlined below:
1. The boundary of the area included in the application has changed to remove the two
northernmost parcels that were owned by the Freda L. Dreiling Living Trust (parcel
146901000021)and D&S Mining(parcel 146912000037). This change decreased the overall
acreage of the site by 67± acres so that the total area being permitted is now 1,152± acres.
2. As a result of removing these two parcels,there will no longer be access to Riverbend off of State
Highway 52. Instead, access will be taken off of Weld County Road 23 at Weld County Road
10.
3. In response to the boundary change, a trail that was originally planned to go through the project
up to Highway 52 has now been rerouted to loop through the property and connect to County
Road 23 via County Road 10.
4. Cell 5 in Phase 5 was reconfigured to change an open water pond into an augmentation recharge
pond.
5. In response to floodplain concerns, a berm south of the proposed water storage pond in Cell!, the
Plant Area was split into two separate berms to allow for the flow of water.
6. Two water storage ponds in Cell 1,the Plant Area were combined into one large pond.
7. Technical changes that were made in conjunction with the Division of Minerals and Geology
(DMG) permit are included in this revised set of maps.
8. Note 17 of the Development Standards has been modified to state that the hours of operation will
comply with Section 23-4-290 of the Weld County Code.
9. The number of acres to be mined at the site per year has changed from approximately 25-30 to
approximately 40-50.

RE: CASE #AmUSR 1259, RIVERBEND/LAFARGE WEST INC.
Dear Mr. Dent:
On behalf of Lafarge West, Inc., I am responding to your letter dated August, 19, 2005.
Although the Riverbend site includes approximately 1152 acres, a majority of the
property is not owned by Lafarge but is being leased for purposes of gravel mining and
reclamation. The permitted property will be an active mine site for approximately 34
years, depending upon market conditions. Access to the site will be restricted during the
life of the mine.
However, representatives of Lafarge are available to discuss your future needs and would
be happy to meet with you. Please provide us with more specifics about the timing and
location of proposed facilities and contact me at(303-774-0173) to set up an
appointment. Thank you for your consideration.

RE: RIVERBEND, AmUSR-1259
Dear Ms. Prather:
On behalf of Lafarge West, Inc., I am responding to your referral comments dated August
5, 2005 regarding the Riverbend Use by Special Review#1259. The potential primary
and secondary trails identified on the Reclamation Plans will be developed in conjunction
with the final reclamation of the site. However, the site will be mined over a period of
approximately 34 years, dependent upon market conditions. Although concurrent
reclamation will take place in increments of 40-50 acres throughout the life of the mine,
the property will be an active mine and will not be open to the public during that time.
Further the specific location of the trails will be refined as mining and reclamation
proceed. We have met with the trails committee for the South Platte River Heritage Plan
and they supported our Reclamation Plan in conjunction with their plans to extend the
trails along County roads.
Please contact me if you have any questions. Thank you for your consideration.
Sincerely,

RE: Response to correspondence to Weld County dated September 13, 2005 for the
Specific Development Plan and Special Use Permit for Riverbend AmUSR-1259 by
Lafarge West,Inc.
Dear Mr. Danny and Mr. Adams:
We would like to take this opportunity to respond to concerns raised in your letter to Weld
County. Below you will find a listing of your concerns with Lafarge's response below.
1. Noise Pollution
Based on previous noise studies that have been conducted for other gravel mining
operations, it has been shown that constructing berms around the plant site operations is
the most effective way to reduce the noise levels heard off-site. Lafarge will construct
berms along WCR 6 (on the south side of the plant site area) as well as along the eastern
side of the plant site area (roughly parallel to U.S. Highway 85).
As a reference, the noise level measured for a passenger car or diesel truck traveling 40
mph is between 75dB(A) and 80 dB(A) at 25' and 50', respectively. The ambient noise
from traffic along Highway#85 will continue to be the primary source of noise that will
affect the residents of the Rocky Mountain Vista Mobile Home Park. With the
construction of berms and material stockpiles located around equipment in the processing
area, the maximum noise levels heard offsite typically range between 40 and 50 dB(A).
For the average human an increase of the measured noise level of 10 dB is subjectively
perceived as being twice as loud or half as loud for a 10dB decrease. Under Colorado
Statute, maximum permissible noise levels adjacent to a residential area is 55dB(A)
during daytime hours (defined as 7 AM to 7 PM) and 50 dB(A) during evening hours
(defined as 7 PM to 7 AM).

2. Fugitive airborne dust
Lafarge prepared a Dust Abatement Plan which was included with their application to
amend the existing Use by Special Review application to Weld County. Lafarge will
incorporate a number of measures at the Riverbend site to minimize the release of
fugitive particulate emissions from the site. These measures include, but are not limited
to:
• Adequate soil moisture will be maintained during soil removal with water applied
as necessary;
• Berms or stockpiles which will remain in place for longer than six months will be
compacted and revegetated;
• Water will be applied during material handling unless the natural moisture is
sufficient to control emissions;
• Vehicle speed on unpaved roads and disturbed areas shall not exceed a maximum
of 20 mph (speed limit signs will be posted);
• The use of water and/or a chemical stabilizer on unpaved haul roads;
• Reclamation will occur concurrently to minimize the total area disturbed at any
lime;
• Material stockpiles will be watered as necessary; and
The entrance to the site will be paved.
3. Visibility
To minimize the visibility of the plant site and other mining operations at the Riverbend
site, Lafarge West, Inc. has committed to install a berm on the north side of WCR 6
which runs parallel to WCR 6 from the site entrance to the eastern property line and a 20'
tall berm north of WCR 6 which roughly parallels U.S. Highway 85 along the eastern
property line. These berms will shield neighbors to the south and east from the visibility
of the plant site operations. This berm will be installed as soon as mining operations
commence and will be vegetated with native grasses, trees and shrubs. Lafarge West,
Inc. has prepared a view study to show what the Riverbend plant site area will look like
from the vantage point at the intersection of U.S. Highway 85 and WCR 6.
4. Truck Traffic
The main entrance to the site will be off WCR 6 at the plant site. Lafarge will use
conveyors to deliver material from the various mine phases to the plant site, so there will
not be haul truck traffic generated from this project on adjacent roadways. The
designated haul route for truck traffic from this site will be east bound on WCR 6 to U.S.
Highway 85. Trucks will head either north or south on U.S. Highway 85 as the
designated haul route does not include WCR 6 east of U.S. Highway 85. The only truck
traffic crossing U.S. Highway 85 and heading east on WCR 6 would be for local
deliveries. Therefore the Rocky Mountain Vista Mobile Home Park entrance should not
be affected by the daily truck traffic generated from the Riverbend site.

April 13, 2006
S. Water Quality and Quantity
Lafarge West, Inc. developed and submitted a Groundwater Monitoring and Mitigation
Plan to the Division of Minerals and Geology (DMG) with the state of Colorado as part
of the gravel mining permit. The DMG approved the Plan which includes an extensive
monitoring plan to ensure that surrounding property owners are not impacted by
fluctuations to the groundwater elevation. In the Plan, Lafarge commits to implement
mitigation measures if mining or reclamation activities are determined to be a significant
contributing factor to groundwater changes. Given the location of the Rocky Mountain
Vista Mobile Home Park's water supply on the east side of the South Platte River and the
fact that the river will provide a hydrologic barrier which will help to maintain historic
groundwater elevations east of the Riverbend mining operations, Lafarge West, Inc. does
not anticipate there will be adverse impacts to the quality or quantity of water the Park
receives.
We appreciate the opportunity to address your concerns. Please take the time to review these
responses and if you have any further questions or concerns please feel free to contact us. Thank
you for your time.
Sincerely,

1. Reclamation Plan
a. Water Storage Reservoir: Reclaimed shoreline slopes will be no steeper than 3:1.
b. Topsoil: All suitable soil material will be salvaged for topsoil replacement. Topsoil
will be used to reclaim the site. The topsoil will be segregated and stored separately
from the overburden material as required by Rule 3.1.9(1). Berms will be protected
from wind and water erosion by vegetative cover if in place more than one year.
Topsoil samples will be subjected to agricultural testing prior to reclamation to assess
fertilizer requirements. More information is provided in the DMG permit.
c. Re-vegetation: Recommendations have been incorporated into all existing
reclamation plans. The Soil Conservation Services (SCS) and/or the Adams County
Cooperative Extension will be contacted periodically throughout reclamation for
assistance with weed control. Detailed re-vegetation information, as well as seed-mix
information for upland and marsh areas, and for pond areas can be found in the Use-
by-Special Review plans.
2. Surface and subsurface water
a. Lafarge has been working to address all surface and sub-surface water issues as part
of their DMG application. As a condition of their DMG permit, Lafarge is required to
maintain the historic hydrologic balance. Lafarge has developed a comprehensive
groundwater monitoring and mitigation plan which has been submitted to the DMG
and is currently being finalized.
NEIGHBORING COMMUNITIES
1. City of Fort Lupton
a. Lafarge has presented their Riverbend application before the Planning Commission
and City Council at various points in the planning process. As a significant portion of
the property is located with the City of Fort Lupton's Urban Growth Boundary,
Lafarge is committed to working with City Staff and Officials to ensure minimal
impacts to the residents of Fort Lupton. To that end, Lafarge will:
• Install a vegetated berm on the south and east sides of the plant side area to shield
these operations from surrounding landowners and traffic on U.S. Highway 85.
The existing cottonwood gallery to the west and north of the plant site should act
as sufficient buffer to landowners located west of the site.
Mb TETRA TECH RMC Ms. Jacqueline Hatch
November 1,2005

• Use WCR 6 as the primary site access. The existing approved designated haul
route specifies that truck traffic must exit the site heading east on WCR 6 to U.S.
Highway 85. Weld County Public Works, CDOT,Aggregate Industries and
Lafarge collaborated on the improvements to the WCR 6 and U.S. Highway 85
interchange. These improvements were based on increased traffic projections for
this intersection caused by the two mining operations.
2. City of Brighton
a. Primary trail: The primary trail location is shown as "potential"based on the mine
life, which exceeds 35 years. Once reclamation is complete, Lafarge will
coordinate with the appropriate jurisdictions to develop the primary trail
alignment. To the extent that the primary trail location extends across properties
owned by Lafarge, Lafarge can and will provide the primary trail once
reclamation is complete. However, a number of the properties are not owned by
Lafarge and the future primary trail alignment will need to be negotiated with the
individual landowners.
b. Trail timing: None of the proposed trails will be constructed or opened to the
public until after reclamation of the Riverbend site is complete, as required by
MSHA regulations.
c. Potential trails: All trail alignments are shown as "potential"based on the
projected life of the project, which is anticipated to exceed 35 years. Once
''' reclamation is complete,Lafarge is committed to coordinating with the
appropriate jurisdictions and landowners to develop the trail network shown in the
Final Landscape and Reclamation Plan.
