The proposed permit area includes a significant deposit of sand and gravel located in the
alluvium of the South Platte River in Weld County. The site is located west and east US-85.
The western portion is west of State High 60 and east of Weld County Road 25.5. The
eastern portion is directly east of the BNSF Rail Road and north of Weld County Road 36. It
encompasses 113 acres+/-on the west and 26 acres+/-on the east.
Site Preparation:
Initial disturbance of the property will include:, stripping the topsoil and overburden material,
constructing the slurry wall.
Mining:
After the slurry wall installation,scrapers will strip the topsoil and overburden material from a
given phase and place them as berms surrounding the site. Any excess material not needed
for reclamation may be sold or hauled off-site during the life of the mine.
The sand and gravel material will be excavated down 10 feet maximum. Each phase will be
dry-mined using scrapers, bulldozers,front-end loaders, excavators,or similar equipment.
The mining on this site will progress in four phases, ranging in size from 21-23 acres and
proceeding from east to the west.
The operator will develop and comply with a Stormwater Management Plan and Spill,
Prevention, Control and Countermeasures Plan. The operator will notify the Division of
Reclamation and Mine Safety and in the event of a reportable spill.
Processing:
The material will be dry screened or not screened at all and transported by offset by truck.
The processing area will be located on the north side of the site.
Import Material:
Bestway Concrete&Aggregates may import material from and export material to other sites.
The applicant is aware that in accordance with Rule 3.1.5(9)of the Construction Material
Rules and Regulations, if any offsite material is used as backfill, a notarized letter will be
submitted to the Division indicating the materials are inert. The applicant will supply such a
letter to the Division if,at the time of Reclamation,the applicant intends to use off-site material
as backfill.
(b) Earthmoving,
Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in
segregated piles at the edge of the active mine phase. Excavators,front-end loaders, and
bulldozers will be used to excavate the material. Haul trucks will be utilized to transport the
raw material from the active mine phase to the processing area. The phases will be mined at
a 3HAV slope.
