bulldozers. After all the sand and gravel has been removed, the azea will 6e backfilled and
compacted using the stockpiled overburden material, the overburden from the next mining area,
and imported fill materials. The area will be backfilled to the approximate original site grades.
This will be the typical sequence of operation for the sand and gravel mining for the Phase I and
Phase 1l project areas.
Processing the sand and gravel will consist of screens and crushers located near the center of the
project area. Once the materials are processed, they will be stockpiled onsite or loaded into trucks
and trucked offsite.
After all sand and gravel mining has been completed, and stockpiled materials have been removed
from the project site, the entire project area will be regraded to reflect the final grades depicted on
the reclamation plan. Reclamation of the site is expected to be completed 12 years after the start of
sand and gravel mining operations.
(c) Al( water diversion and impoundment's
The project site is hydraulically isolated from upgradient and adjacent property surface flows. An
irrigation ditch located on the adjacent property to the east collects upgradient runoff and diverts it
to the south. Another irrigation ditch, located on the north property line, flows to the west along G
Road and drains into an existing catch basin located at the southeast corner of 23 Road and G
Road. Once the flows enter the catch basin, it is routed through a culvert pipe under G Road and
dump into a large drainage ditch located along the north side of G Road.
During the mining and reclamation process, all precipita[ion within the project site will 6e
collected and remain on the project site. A drainage Swale will be installed along the north, west
and south property lines, which will collect and divert surface flows into a new retention pond
located along the west property line. The retention pond has been sized in accordance with the
City of Grand Junction standards.
Other than the proposed retention pond, there will be no other surface water diversion or
impoundments.
(d) The size ojareas to be worked at arty one time;
During the sand and gravel mining, no more than 5 acres will be mined at any one time.
(e) An approximate timetable to describe the mining operation. The timetable is for the purposes of
establishing relationship between mining and reclamation during the di,~erent phases of the mining
operations. An Operator shall not be required to meet specific dates for initiation, or completion of
mining in a phase as may be identified in the time[able. This does not exempt an operator from
complying with the performance standards stated ojSection 3.1. Such timetable shall include:
• An estimate ojrhe periods of time which will be required jor the various stages of the
operation;
• A description of the size and location of each area to be worked during each phase; and
• Oarlining the sequence in which each stage or phase of the operation will be carried out
Sand and Gravel mining operations are anticipated [o begin in the spring or summer of 2000.
Mining for the sand and gravel will require approxima[ely 10 years, with each phase of the project
requiring five years to complete. Reclamation o(the site will be completed twelve years after the
start of mining operations. The addi[ional two yeah for reclamation are requested to allow time
to deplete all stockpiled materials and complete final site restoration work.
