6.4.4 EXHIBIT D - MINING PLAN
6.4.4 (A) DESCRIPTION OF THE METHOD(S) OF MINING
Mining conducted employs conventional aggregate mining techniques including the use of
excavators and loaders to excavate topsoil, overburden, and aggregate material. Mining is
accomplished by utilizing dewatering trenches around the perimeter of the toe of mining slope to
facilitate dry mining. Haul trucks move materials to be processed at a fixed gravel plant located
on -site. Finished materials are stockpiled where they are loaded into trucks for removal off -site or
to the concrete plant located in the southeastern corner of the site.
6.4.4 (B) EARTHMOVING
The mining operation strips topsoil and overburden to expose the underlying raw aggregate
material deposit. Topsoil is stockpiled on -site and seeded to establish a vegetated cover to
minimize erosion until future reclamation use. Overburden material will be utilized as part of the
mine backfill. Overburden material will typically be stockpiled temporarily (i.e., less than one [1]
year) and used as backfill of earlier mine excavation areas. However, should mining operations
call for overburden materials to be stored over one (1) year, the stockpiles will be seeded with
reclamation seed mix to establish a vegetated cover to minimize erosion until future backfill use.
The exposed raw aggregate material deposit will be excavated and processed.
The equipment used to conduct the earthmoving activities may include dozers, loaders, excavators,
articulated haul trucks, water trucks, and scrapers for the mining and earth moving operations.
Aggregate processing equipment includes feeders, a fixed plant gravel plant with crusher and
screens, sand screw, wash plant, conveyors, stackers, and other miscellaneous processing
equipment.
6.4.4 (C) WATER DIVERSIONS AND IMPOUNDMENTS
The following discusses water diversions and impoundments at the Site:
Mine Pit Dewatering: Mining of the Site utilizes dewatering trenches around the
perimeter of the toe of mining slope to facilitate dry mining. Water is directed into a
pump basin (i.e., sedimentation pond) within the pit to settle out fines prior to being
pumped for discharge (via enclosed pipe or dewatering trench) to the South Platte River
at approved Outfalls 001-A or 003-A.
Wash Plant: Wash plant water is recycled in a continuous loop using on -site
sedimentation ponds. Water for the wash plant is pumped from an on -site sedimentation
pond. The used wash plant water is directed to another on -site sedimentation pond to
allow suspended sediment to settle out. The settled wash plant water is then transferred
Chavers Mining Resource
DRMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
February 2023
Page 4
back to the initial sedimentation pond to be re -used by the wash plant. Settled fines from
used wash plant process water sedimentation pond will be excavated and used as backfill.
Industrial Well: In addition to sand and gravel pit mining, a concrete production plant is
located on Cell 1 at the Site. The concrete production plant utilizes groundwater from the
on -site industrial alluvial well (Well Permit No. 80120-F) located near the southeast
corner of the Site.
ASCI maintains replacement water lease(s) and approved Substitute Water Supply Plan (SWSP)
through the Division of Water Resources (DWR) annually to account for out -of -priority depletions
resulting from the water diversions and impoundments.
6.4.4 (D) SIZE OF AREA(S) TO BE WORKED ON AT ANY ONE TIME
The maximum size of pit areas to be worked on at any one-time is approximately 20 acres.
6.4.4 (E) APPROXIMATE TIMETABLE FOR MINING OPERATION
Approximately 75 -acres are mineable at the Chavers Mining Resource. The ±75 mineable acres
has been divided into six (6) mining cells (Cell 1 through Cell 6). Cell 1 (approx. 4 acres) has
already been mined and backfilled. The mining operation is estimated to last for another 8 years;
however, this could vary depending upon market conditions. Multiple cells may be exposed at
one-time for concurrent mining and backfilling operations.

6.4.5 EXHIBIT E — RECLAMATION PLAN
6.4.5 (1) PREPARATION OF THE RECLAMATION PLAN
This revised reclamation plan includes specific details related to final reclamation of the Site as
rangeland use after backfilling. Specific information contained in this document includes final
grading, seeding, fertilizing, revegetation, topsoiling, and weed control.
6.4.5 (2) RECLAMATION PLAN REQUIREMENTS
6.4.5 (2)(a) Description of Reclamation Plan
Reclamation of the Site will return the land to rangeland use after backfilling. The benefits of this
plan include:
Creating usable property for agriculture use.
Increasing the visual attractiveness of the Site and surrounding area.
Providing private entities an alternative for disposal of clean materials (e.g., basement
over -excavations for housing developments).
Increased employment opportunities created by the backfill operations and reclamation of
this Site.
Should ASCI decide to sell the property after reclamation is complete, this plan will
allow for long-term flexibility when evaluating future development options. This could
result in revenue to the City of Fort Lupton and the State in future taxes pending the
redevelopment plan by a new owner.
Of the 95 -acre permit area for the Chavers Mining Resource, approximately 75 of the acres are
mineable. ASCI is expanding the affected area ±75 acres to ±87 acres for surface use disturbances
only (no change to the ±75 acres to be mined will occur). The ±75 mineable acres has been divided
into six (6) mining cells (Cell 1 through Cell 6). Cell 1 (approx. 4 acres) has already been mined
and backfilled as it is the location of the existing concrete plant. With this amendment (AM -02),
reclamation of the remaining ±71 acres (i.e., Cells 2 - 6) will also be backfilled and the entire ±87
acres reclaimed for rangeland use.
Backfill Material: Backfill material will consist of on -site overburden, on -site crusher
fines, wash plant fines, and imported clean, uncontaminated material consistent with the
Construction Material Rule No. 1, Section 1.1 (22). It is ASCI's intention to use
primarily native/natural earth and aggregate materials (i.e., sand, gravel, and rock) for
backfill material. It is especially important to ASCI that only clean, uncontaminated
materials are delivered to the Site. All backfill materials generated off -site will be
delivered by reputable pre -approved contractors that have a history of working with
ASCI and will adhere to the Site rules and guidelines. ASCI will collaborate with the
Chavers Mining Resource
DRMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
February 2023
Page 7
contractors to obtain assurances that backfill materials are free of contaminants and are
native or natural materials. ASCI will exercise every effort to learn as much as
reasonably possible about the backfill materials received at the Site to ensure that those
materials are free of contaminants. All backfill materials will be inspected upon entry to
the Site and while being unloaded using visual and/or olfactory methods to ensure no
potentially contaminated materials are received. If evidence of possible contamination is
observed, loads will be rejected and will not be allowed to be left on -site by the
contractor. No contaminated materials will be accepted or allowed on -site. Any
asphalt or concrete materials received will continue to be diverted to the recycled
aggregate materials operation at the Site.
Backfilling Process: After an area of the property has been mined of sand and gravel,
backfilling operations will begin once they can be safely conducted. ASCI will conduct
backfill operations concurrent with mining operations whenever possible. ASCI will not
exceed exposed active mining and backfill pit areas of approximately 20 acres at any one-
time. Backfill material will be imported to the Site with articulated dump trucks and/or
highway dump trucks. The material will be placed and spread in one (1) to two (2) -foot
lifts using haul trucks, bulldozers, excavators, and/or loaders. Compaction will take place
during the filling process, as haul trucks and heavy equipment traverse over the fill.
Temporary excavation slopes and temporary stockpiled material slopes may range from
1:1 to 3:1 depending on soil conditions in the mine. All slopes will be maintained for site
safety and to minimize material erosion. Areas will be backfilled to a rough grade (i.e.,
within approximately 2 - 3 feet of final grade).
Grading and Topsoil: Once the backfill is near rough grade across the Site, the surface
contours of the affected area will be graded to approximately six (6) inches below the
final grade across the Site. After contour grading is complete, a topsoil cover
approximately six (6) inches thick will be placed on top of the backfill to reach
topographic elevations prior to mining (i.e., final grade). The final grade will control
water runoff, erosion, and siltation to protect all areas outside the mine and allow surface
drainage to flow gently as sheet flow to the northeast, consistent with pre -development
drainage.
To ensure grading requirements are met, elevations will be checked periodically by ASCI
during the reclamation process. This will continue until the final grade is achieved with
backfill materials and topsoil cover. A final topography survey will be conducted by
ASCI after topsoil has been placed, but before seeding occurs to ensure that the Site
topography is at pre -mining elevations and sloped for positive drainage. All surveys will
be conducted by aerial drone. The allowable vertical variation will be approximately one
(1) foot given that the final topography will be slightly undulating in areas to mimic the
original landform. Once topography across the Site is within acceptable limits, ASCI will

Amendment No. 2 (AM -02)
February 2023

proceed with the revegetation process. The approximate final contours of the Site are
shown on Exhibit F - Reclamation Plan Map.
■ Seeding and Growth Monitoring: The topsoil layer will be seeded with a native grass
seed mix to return the property to rangeland use. Growth of the grass will be monitored
quarterly to ensure a successful transition back to rangeland use.
6.4.5 (2)(b) Land Uses in the Vicinity
Reclamation to rangeland land is a positive and useful post -closure land use that is compatible
with surrounding uses which include multiple sand and gravel mines, oil and gas industry sites,
and other rangeland/agricultural lands.
6.4.5 (2)(c) Reclamation Performance Standards
The following sections describe how this reclamation plan meets applicable requirements of
Construction Materials Rule No. 3, Section 3.1 Reclamation Performance Standards.
RULE 3: Section 3.1 - Reclamation Performance Standards
3.1.1 Establish Post Mining Land Use: The post -mining land use shall return the property to
rangeland use. The Site is currently zoned Agricultural by the City of Fort Lupton.
3.1.2 Reclaiming Substituted Land: Not Applicable
3.1.3 Time Limited and Phased Reclamation: A phased reclamation approach will be
implemented. Reclamation will occur in two (2) phases:
Reclamation Phase 1: Backfill — Reclamation Phase 1 will backfill excavated
Cells 2 — 6 with on -site overburden, crusher fines, wash plant fines, and imported
clean, uncontaminated material. Backfill will occur concurrently with mining
whenever possible; however, backfill will continue after mining is complete.
Reclamation Phase 1 will be complete when backfill of the entire Site is within
approximately 2 - 3 feet of final grade as indicated by ASCI survey. Should
completion of Reclamation Phase 1 not be feasible within five (5) years from the
date ASCI informs the DRMS that all material extraction and stockpile removal is
complete, an extension will be submitted based on the remaining backfill volume
required at that time.
Reclamation Phase 2: Grading, Topsoil, Seeding, and Growth Monitoring — In
Reclamation Phase 2, ASCI will remove existing structures, grade Site contours
for the +87 acres of affected area to approximately six (6) inches below the final
grade, and place a final cover topsoil layer approximately six (6) inches thick
across the affected area. Changes to topography will be made as necessary until the
final grade is within acceptable limits and returned to pre -mining elevations. Once
final grade is achieved, site seeding, fertilizing, and mulching will occur in the
Chavers Mining Resource
DRMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
February 2023
Page 9
subsequent fall season. Growth and progress of the grass will be monitored
quarterly to ensure a successful transition back to rangeland use. It is anticipated
that a successful transition will occur within five (5) years from the date ASCI
informs the DRMS that Reclamation Phase 2 has commenced.
3.1.4 Public Use: The public will not be allowed on the land while mining and reclamation
activities are in progress. After reclamation is complete and the bond released, the public
will only have access to the land adjacent to the South Platte River that will be dedicated
to the City of Fort Lupton.
3.1.5 Reclamation Measures — Materials Handling: Measures will be taken to meet the
following requirements.
(1) The Site will be graded to the approximate topographic elevations prior to mining.
The approximate final contours of the Site are shown on Exhibit F - Reclamation Plan
Map.
(2) No toxic or acid-forming materials will be included in backfill material. All backfill
materials will be compacted during the filling process.
(3) Grading will be done to control erosion and siltation on the affected lands and protect
outside areas from slides. No high walls will be left exposed.
(4) Once backfill activities are complete at the Site, grading will occur as quickly as
feasible.
(5) No acid-forming or toxic producing materials are associated with materials mined at
the Site. On -site refuse is maintained by contracted vendors to control unsightliness and
protect the South Platte River drainage system.
(6) No drill or auger holes, adits, or shafts are associated with the mining operation. All
monitoring wells will be properly abandoned prior to completing reclamation.
(7) Contouring the site back to approximate pre-existing topographic elevations will
result in maximum slope(s) that are compatible with surrounding conditions and
selected land use.
(8) The grade of the land will allow for use of farm machinery to traverse the Site.
(9) This document, Amendment No. 2 (AM -02), serves as ASCI's notice of intent to
backfill using clean, uncontaminated materials generated outside of the approved permit
area in addition to materials generated within the permitted area.
(a) The location of backfill will occur in Cells 2 — 6.
(b) The approximate total volume of backfill material is estimated to be + 3.0
million cubic yards.
(c) A signed affidavit certifying that the material is clean and inert, as defined by
Rule 1.1(22) is provided as Attachment 1 of this document.

the completion of Reclamation Phase 1 (estimated 2035 - see Section
6.4.5(2)(e)).
(e) The backfilled Site will result in a post -mining configuration that is
compatible with the post -mining land use (i.e., rangeland) being requested for
approval by this Amendment No. 2 (AM -02).
(f) The material will be placed and spread in 1 -to -2 -foot lifts using haul trucks,
bulldozers, excavators, and/or loaders. Compaction will take place during the
filling process, as haul trucks and heavy equipment traverse over the fill.
(10) All mined material not compatible for off -site use (e.g., fines) will be backfilled to
prevent any release of unauthorized fine material to the surface drainage system.
(11) No unauthorized release of pollutants to groundwater will occur from materials
mined, handled, or used as backfill within the permit area. No toxic or acid producing
materials are used in the mining process.
3.1.6 Water — General Requirements: ASCI will minimize disturbances to the prevailing
hydrologic balance and water quality of systems (surface and groundwater) both during
and after mining and reclamation phases.
(1) Hydrology and Water Quality: ASCI will continue to comply with applicable
Colorado water laws and regulations to ensure no injury occurs to existing water rights
and maintain water quality standards of the Water Quality Control Commission

Notes:
pls = Pure Live Seed
Based on this seed mixture, an application rate of approximately 20.0 to 28.0 pls/ac will be used.
Due to the common use of these grass species in the area, the availability of viable seeds in
sufficient quantities is not considered to be an issue. Soil will be disced prior to seeding. Fertilizer
be utilized in conjunction with seeding. A standard application of fertilizer will be used and applied
at an appropriate rate (e.g., 250 lbs./acre). The total area to be seeded and fertilized is
approximately 75 acres. Seeding and fertilizing will be completed as soon as possible after the
overburden soil is backfilled, smoothed to conform to the reclamation topography, and the final
layer of topsoil is placed and disced. Optimal periods of seeding are in the fall, before the first
freeze (before November lst) or in the spring from late -March up to April 30th. A standard
application of straw mulch will be used and applied at an appropriate rate (e.g., 2 tons/acre) to the
approximately 75 acres.
Following revegetation, weed management strategies will be implemented to facilitate and achieve
native grassland. Quarterly inspections to monitor revegetation progress and identify weed
infestations will be conducted until the reclamation bond is released. ASCI will implement
cultural, mechanical, and biological control methods including an aggressive mowing program to
prevent the growth and establishment of weeds as mandated by Colorado State Law (C.R.S. Title
35 Article 5.5 Colorado Noxious Weed Act). If needed, chemical/herbicide application will be
applied to further control weed infestations.
6.4.5 (2)(e) Schedule for Implementation
Reclamation will occur concurrently with mining wherever possible to backfill material into
previously mined areas. However, temporary stockpiling may occur for short durations. The
anticipated reclamation schedule is presented in the following table.

6.4.7 EXHIBIT G - WATER INFORMATION
6.4.7(1) IF OPERATION IS NOT EXPECTED TO DIRECTLY AFFECT SURFACE OR
GROUNDWATER
Not applicable.
6.4.7(2) IF OPERATION IS EXPECTED TO DIRECTLY AFFECT SURFACE OR
GROUNDWATER
6.4.7(2)(a) Surface Water and Groundwater Systems Affected by Operation
With this Amendment (AM -02), no change will occur to the surface water and groundwater
systems directly affected previously identified. Operations at the Chavers Mining Resource affect
surface water associated with the South Platte River located to the west of the mine and
groundwater associated with the South Platte River alluvial aquifer (i.e., uppermost aquifer).
6.4.7(2)(b) Known Aquifers
South Platte River alluvial aquifer (unnamed aquifer).
6.4.7(2)(c) Dewatering Operations and Runoff
Mine process water, which includes groundwater from the dewatering operations and stormwater
that collects in the mine pit, is directed into a settling basin within the pit to allow fine sediments
to settle out before being pumped for discharge to the South Platte River. ASCI will maintain a
topography at the Site to direct stormwater runoff from disturbed areas, piled material, and
operating surfaces that is not collected in the mine pit to areas within the permit boundary where
the water can percolate into the ground.
6.4.7(3) PROJECT WATER REQUIREMENTS
ASCI submits SWSPs annually to the Colorado Division of Water Resources (DWR) for approval
to refine the estimated project water requirements each year based upon the anticipated site
conditions as mining and/or reclamation progresses. The current approved SWSP estimates project
water requirements will be 51.20 acre-feet over the 12 -month period covered by the plan (August
2022 to July 2023).
6.4.7(4) REPLACEMENT WATER SOURCES
ASCI utilizes a long-standing relationship with the City of Aurora to supply the project water
requirements. Currently, ASCI holds a water lease with the City of Aurora to supply replacement
water for the Site from 2022 through 2026. ASCI will continue to utilize this relationship
throughout mining and reclamation of the mine.

6.4.4 EXHIBIT D - MINING PLAN
6.4.4 (A) DESCRIPTION OF THE METHOD(S) OF MINING
Mining conducted employs conventional aggregate mining techniques including the use of
excavators and loaders to excavate topsoil, overburden, and aggregate material. Mining is
accomplished by utilizing dewatering trenches around the perimeter of the toe of mining slope to
facilitate dry mining. Haul trucks move materials to be processed at a fixed gravel plant located
on -site. Finished materials are stockpiled where they are loaded into trucks for removal off -site or
to the concrete plant located in the southeastern corner of the site.
6.4.4 (B) EARTHMOVING
The mining operation strips topsoil and overburden to expose the underlying raw aggregate
material deposit. Topsoil is stockpiled on -site and seeded to establish a vegetated cover to
minimize erosion until future reclamation use. Overburden material will be utilized as part of the
mine backfill. Overburden material will typically be stockpiled temporarily (i.e., less than one [1]
year) and used as backfill of earlier mine excavation areas. However, should mining operations
call for overburden materials to be stored over one (1) year, the stockpiles will be seeded with
reclamation seed mix to establish a vegetated cover to minimize erosion until future backfill use.
The exposed raw aggregate material deposit will then be excavated and processed.
The equipment used to conduct the earthmoving activities may include dozers, loaders, excavators,
articulated haul trucks, water trucks, and scrapers for the mining and earth moving operations.
Aggregate processing equipment includes feeders, a fixed plant gravel plant with crusher and
screens, sand screw, wash plant, conveyors, stackers, and other miscellaneous processing
equipment.
6.4.4 (C) WATER DIVERSIONS AND IMPOUNDMENTS
The following discusses water diversions and impoundments at the Site:
Mine Pit Dewatering: Mining of the Site utilizes dewatering trenches around the
perimeter of the toe of mining slope to facilitate dry mining. Water is directed into a
pump basin (i.e., sedimentation pond) within the pit to settle out fines prior to being
pumped for discharge (via enclosed pipe or dewatering trench) to the South Platte River
at approved Outfalls 001-A or 003-A.
Wash Plant: Wash plant water is recycled in a continuous loop using on -site
sedimentation ponds. Water for the wash plant is pumped from an on -site sedimentation
pond. The used wash plant water is directed to another on -site sedimentation pond to
allow suspended sediment to settle out. The settled wash plant water is then transferred
Chavers Mining Resource
DRMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
November 2022
Page 3
back to the initial sedimentation pond to be re -used by the wash plant. Settled fines from
used wash plant process water sedimentation pond will be excavated and used as backfill.
Industrial Well: In addition to sand and gravel pit mining, a concrete production plant is
located on Cell 1 at the Site. The concrete production plant utilizes groundwater from the
on -site industrial alluvial well (Well Permit No. 80120-F) located near the southeast
corner of the Site.
ASCI maintains replacement water lease(s) and approved Substitute Water Supply Plan (SWSP)
through the Division of Water Resources (DWR) annually to account for out -of -priority depletions
resulting from the water diversions and impoundments.
6.4.4 (D) SIZE OF AREA(S) TO BE WORKED ON AT ANY ONE TIME
The maximum size of pit areas to be worked on at any one-time is approximately 20 acres.
6.4.4 (E) APPROXIMATE TIMETABLE FOR MINING OPERATION
Of the 95 -acre permit area for the Chavers Mining Resource, approximately 75 of the acres are
mineable. The ±75 mineable acres has been divided into six (6) mining cells (Cell 1 through Cell
6). Cell 1 (approx. 4 acres) has already been mined and backfilled. The mining operation is
estimated to last for another 8 years; however, this could vary depending upon market conditions.
Multiple cells may be exposed at one-time for concurrent mining and backfilling operations.

6.4.5 EXHIBIT E - RECLAMATION PLAN
6.4.5 (1) PREPARATION OF THE RECLAMATION PLAN
This revised reclamation plan includes specific details related to final reclamation of the Site as
general agricultural use after backfilling. Specific information contained in this document includes
final grading, seeding, fertilizing, revegetation, topsoiling, and weed control.
6.4.5 (2) RECLAMATION PLAN REQUIREMENTS
6.4.5 (2)(a) Description of Reclamation Plan
Reclamation of the Site will return the land to agricultural use after backfilling. The benefits of
this plan include:
Creating usable property for agriculture use.
Increasing the visual attractiveness of the Site and surrounding area.
Providing private entities an alternative for disposal of clean materials (e.g., basement
over -excavations for housing developments).
Increased employment opportunities created by the backfill operations and reclamation of
this Site.
Should ASCI decide to sell the property after reclamation is complete, this plan will
allow for long-term flexibility when evaluating future development options. This could
result in revenue to the City of Fort Lupton and the State in future taxes pending the
redevelopment plan by a new owner.
Of the 95 -acre permit area for the Chavers Mining Resource, approximately 75 of the acres are
mineable. The ±75 mineable acres has been divided into six (6) mining cells (Cell 1 through Cell
6). Cell 1 (approx. 4 acres) has already been mined and backfilled as it is the location of the
existing concrete plant. With this amendment (AM -02), reclamation of the remaining ±71 acres
(i.e., Cells 2 - 6) will also be backfilled and the entire Site returned to general agricultural use.
Backfill Material: Backfill material will consist of on -site overburden, on -site crusher
fines, wash plant fines, and imported clean, uncontaminated material consistent with the
Construction Material Rule No. 1, Section 1.1 (22). It is ASCI's intention to use
primarily native/natural earth and aggregate materials (i.e., sand, gravel, and rock) for
backfill material. It is especially important to ASCI that only clean, uncontaminated
materials are delivered to the Site. All backfill materials generated off -site will be
delivered by reputable pre -approved contractors that have a history of working with
ASCI and will adhere to the Site rules and guidelines. ASCI will collaborate with the
contractors to obtain assurances that backfill materials are free of contaminants and are
native or natural materials. ASCI will exercise every effort to learn as much as
Chavers Mining Resource
DRMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
November 2022
Page 6
reasonably possible about the backfill materials received at the Site to ensure that those
materials are free of contaminants. All backfill materials will be inspected upon entry to
the Site and while being unloaded using visual and/or olfactory methods to ensure no
potentially contaminated materials are received. If evidence of possible contamination is
observed, loads will be rejected and will not be allowed to be left on -site by the
contractor. No contaminated materials will be accepted or allowed on -site. Any
asphalt or concrete materials received will continue to be diverted to the recycled
aggregate materials operation at the Site.
Backfilling Process: After an area of the property has been mined of sand and gravel,
backfilling operations will begin once they can be safely conducted. ASCI will conduct
backfill operations concurrent with mining operations whenever possible. ASCI will not
exceed exposed active mining and backfill pit areas of approximately 20 acres at any one-
time. Backfill material will be imported to the Site with articulated dump trucks and/or
highway dump trucks. The material will be placed and spread in one (1) to two (2) -foot
lifts using haul trucks, bulldozers, excavators, and/or loaders. Compaction will take place
during the filling process, as haul trucks and heavy equipment traverse over the fill.
Temporary excavation slopes and temporary stockpiled material slopes may range from
1:1 to 3:1 depending on soil conditions in the mine. All slopes will be maintained for site
safety and to minimize material erosion. Areas will be backfilled to a rough grade (i.e.,
within approximately 2 - 3 feet of final grade).
Grading and Topsoil: Once the backfill is near rough grade across the Site, the surface
contours will be graded to approximately six (6) inches below the final grade across the
Site. After contour grading is complete, a topsoil cover approximately six (6) inches thick
will be placed on top of the backfill to reach topographic elevations prior to mining (i.e.,
final grade). The final grade will control water runoff, erosion, and siltation to protect all
areas outside the mine and allow surface drainage to flow gently as sheet flow to the
northeast, consistent with pre -development drainage. The final grade will allow general
agriculture operations, farm machinery, and livestock to traverse the area.
To ensure grading requirements are met, elevations will be checked periodically by ASCI
during the reclamation process. This will continue until the final grade is achieved with
backfill materials and topsoil cover. A final topography survey will be conducted by
ASCI after topsoil has been placed, but before seeding occurs to ensure that the Site
topography is at pre -mining elevations and sloped for positive drainage. All surveys will
be conducted by aerial drone. The allowable vertical variation will be approximately one
(1) foot given that the final topography will be slightly undulating in areas to mimic the
original landform. Once topography across the Site is within acceptable limits, ASCI will
proceed with the revegetation process. The approximate final contours of the Site are
shown on Exhibit F - Reclamation Plan Map.

■ Seeding and Growth Monitoring: The topsoil layer will be seeded with a native grass
seed mix to return the property to general agricultural use. Growth of the grass will be
monitored quarterly to ensure a successful transition back to agricultural use.
6.4.5 (2)(b) Land Uses in the Vicinity
Reclamation to general agricultural land is a positive and useful post -closure land use that is
compatible with surrounding uses which include multiple sand and gravel mines, oil and gas
industry sites, and other agricultural lands.
6.4.5 (2)(c) Reclamation Performance Standards
The following sections describe how this reclamation plan meets applicable requirements of
Construction Materials Rule No. 3, Section 3.1 Reclamation Performance Standards.
RULE 3: Section 3.1- Reclamation Performance Standards
3.1.1 Establish Post Mining Land Use: The post -mining land use shall return the property to
general agricultural use. The Site is currently zoned Agricultural by the City of Fort
Lupton.
3.1.2 Reclaiming Substituted Land: Not Applicable
3.1.3 Time Limited and Phased Reclamation: A phased reclamation approach will be
implemented. Reclamation will occur in two (2) phases:
Reclamation Phase 1: Backfill — Reclamation Phase 1 will backfill excavated
Cells 2 — 6 with on -site overburden, crusher fines, wash plant fines, and imported
clean, uncontaminated material. Backfill will occur concurrently with mining
whenever possible; however, backfill will continue after mining is complete.
Reclamation Phase 1 will be complete when backfill of the entire Site is within
approximately 2 - 3 feet of final grade as indicated by ASCI survey. Should
completion of Reclamation Phase 1 not be feasible within five (5) years from the
date ASCI informs the DRMS that all material extraction and stockpile removal is
complete, an extension will be submitted based on the remaining backfill volume
required at that time.
Reclamation Phase 2: Grading, Topsoil, Seeding, and Growth Monitoring — In
Reclamation Phase 2, ASCI will remove existing structures, grade Site contours to
approximately six (6) inches below the final grade, and place a final cover topsoil
layer approximately six (6) inches thick across Cells 1 - 6. Changes to topography
will be made as necessary until the final grade is within acceptable limits and
returned to pre -mining elevations. Once final grade is achieved, site seeding,
fertilizing, and mulching will occur in the subsequent fall season. Growth and
progress of the grass will be monitored quarterly to ensure a successful transition
Chavers Mining Resource
DBMS Permit No. M-2015-030
Amendment No. 2 (AM -02)
November 2022
Page 8
back to agricultural use. It is anticipated that a successful transition back to
agricultural use will occur within five (5) years from the date ASCI informs the
DRMS that Reclamation Phase 2 has commenced.
3.1.4 Public Use: The public will not be allowed on the land while mining and reclamation
activities are in progress. After reclamation is complete and the bond released, the public
will only have access to the land adjacent to the South Platte River that will be dedicated
to the City of Fort Lupton.
3.1.5 Reclamation Measures — Materials Handling: Measures will be taken to meet the
following requirements.
(1) The Site will be graded to the approximate topographic elevations prior to mining.
The approximate final contours of the Site are shown on Exhibit F - Reclamation Plan
Map.
(2) No toxic or acid-forming materials will be included in backfill material. All backfill
materials will be compacted during the filling process.
(3) Grading will be done to control erosion and siltation on the affected lands and protect
outside areas from slides. No high walls will be left exposed.
(4) Once backfill activities are complete at the Site, grading will occur as quickly as
feasible.
(5) No acid-forming or toxic producing materials are associated with materials mined at
the Site. On -site refuse is maintained by contracted vendors to control unsightliness and
protect the South Platte River drainage system.
(6) No drill or auger holes, adits, or shafts are associated with the mining operation. All
monitoring wells will be properly abandoned prior to completing reclamation.
(7) Contouring the site back to approximate pre-existing topographic elevations will
result in maximum slope(s) that are compatible with surrounding conditions and
selected land use.
(8) The grade of the land will allow for use of farm machinery to traverse the Site.
(9) This document, Amendment No. 2 (AM -02), serves as ASCI's notice of intent to
backfill using clean, uncontaminated materials generated outside of the approved permit
area in addition to materials generated within the permitted area.
(a) The location of backfill will occur in Cells 2 — 6.
(b) The approximate total volume of backfill material is estimated to be ± 3.0
million cubic yards.
(c) A signed affidavit certifying that the material is clean and inert, as defined by

Based on this seed mixture, an application rate of approximately 20.0 to 28.0 pls/ac will be used.
Due to the common use of these grass species in the area, the availability of viable seeds in
sufficient quantities is not considered to be an issue. Soil will be disced prior to seeding. Fertilizer
be utilized in conjunction with seeding. A standard application of fertilizer will be used and applied
at an appropriate rate (e.g., 250 lbs./acre). The total area to be seeded and fertilized is
approximately 75 acres. Seeding and fertilizing will be completed as soon as possible after the
overburden soil is backfilled, smoothed to conform to the reclamation topography, and the final
layer of topsoil is placed and disced. Optimal periods of seeding are in the fall, before the first
freeze (before November 1st) or in the spring from late -March up to April 30th. A standard
application of straw mulch will be used and applied at an appropriate rate (e.g., 2 tons/acre) to the
approximately 75 acres.
Following revegetation, weed management strategies will be implemented to facilitate and achieve
native grassland. Quarterly inspections to monitor revegetation progress and identify weed
infestations will be conducted until the reclamation bond is released. ASCI will implement
cultural, mechanical, and biological control methods including an aggressive mowing program to
prevent the growth and establishment of weeds as mandated by Colorado State Law (C.R.S. Title
35 Article 5.5 Colorado Noxious Weed Act). If needed, chemical/herbicide application will be
applied to further control weed infestations.
6.4.5 (2)(e) Schedule for Implementation
Reclamation will occur concurrently with mining wherever possible to backfill material into
previously mined areas. However, temporary stockpiling may occur for short durations. The
anticipated reclamation schedule is presented in the following table.

6.4.7 EXHIBIT G - WATER INFORMATION
6.4.7(1) IF OPERATION IS NOT EXPECTED TO DIRECTLY AFFECT SURFACE OR
GROUNDWATER
Not applicable.
6.4.7(2) IF OPERATION IS EXPECTED TO DIRECTLY AFFECT SURFACE OR
GROUNDWATER
6.4.7(2)(a) Surface Water and Groundwater Systems Affected by Operation
With this Amendment (AM -02), no change will occur to the surface water and groundwater
systems directly affected previously identified. Operations at the Chavers Mining Resource affect
surface water associated with the South Platte River located to the west of the mine and
groundwater associated with the South Platte River alluvial aquifer (i.e., uppermost aquifer).
6.4.7(2)(b) Known Aquifers
South Platte River alluvial aquifer (unnamed aquifer).
6.4.7(2)(c) Dewatering Operations and Runoff
Mine process water, which includes groundwater from the dewatering operations and stormwater
that collects in the mine pit, is directed into a settling basin within the pit to allow fine sediments
to settle out before being pumped for discharge to the South Platte River. ASCI will maintain a
topography at the Site to direct stormwater runoff from disturbed areas, piled material, and
operating surfaces that is not collected in the mine pit to areas within the permit boundary where
the water can percolate into the ground.
6.4.7(3) PROJECT WATER REQUIREMENTS
ASCI submits SWSPs annually to the Colorado Division of Water Resources (DWR) for approval
to refine the estimated project water requirements each year based upon the anticipated site
conditions as mining and/or reclamation progresses. The current approved SWSP estimates project
water requirements will be 51.20 acre-feet over the 12 -month period covered by the plan (August
2022 to July 2023).
6.4.7(4) REPLACEMENT WATER SOURCES
ASCI utilizes a long-standing relationship with the City of Aurora to supply the project water
requirements. Currently, ASCI holds a water lease with the City of Aurora to supply replacement
water for the Site from 2022 through 2026. ASCI will continue to utilize this relationship
throughout mining and reclamation of the mine.
