Item 1,2.
Tax ID number
Item 3.
The attached Figure 1 shows the plan view for the proposed quarry site. The azea to be actively mined will
be 300' by 300'. The land affected by the actively mined site and the overburden berm will be 350' by
350'. The total area of potential impact is 430' by 500' or 4,94 acres. The 4.94 acres includes land outside
of the berm that will be affected by reclamation activity of a dozer used to push the berm material back
over the site once the mining is completed.
The soils on the site include soil types #54 -Travelers Very Stony Loam and #18 - Garita Cobbly Loam.
The proposed impact surface is on a very arid, upland mesa with very, very sparse vegetation. The soils are
little more than an occasional patch of a thin veneer of soil surrounded by the exposed gravel and cobble
which is the overburden material. For all practical purposes, [here is no top soil to excavate and store.
The overburden will be piled in a berm immediately surrounding the excavation site. The berm will have a
2:1 slope.
LOCATION
The proposed quarry will be located in the SE '/< of the S W '/, of Section 18 as shown in the attached
Figure 2. The site in on top of, and near the edge of, a mesa. Mr. Porco's lease agreement is correct with a
description of the S '/~ of the S W '/, of Section 18. The Conejos County Resolution Number C-02-32 is also
correct and the pit is to be with the SE '/, of the S W %. of Section 18. Permit area boundaries will be posted
in the field with wooden posts.
EXIIIBIT C:
There will be no fuel, oil, lubricants or anti-freeze stored at the mine site.
Blasting will be performed by a licensed subcontractor. There will be no blasting materials stored at the
mine site.
EXEIIBIT D:
The attached Figure 1 shows the plan view for the proposed quarry site. The azea to be actively mined will
be 300' by 300'. The land affected by the actively mined site and the overburden berm will be 350' by
350'. The total area of potential impact is 430' by 500' or 4,94 acres. The 4.94 acres includes land outside
of the berm that will be affected by reclamation activity of a dozer used to push the berm material back
over the site once the mining is completed.
Please refer also to previously submitted EXFIIBIT D for per-acre reclamation cost estimates.
EXFIIBIT E:
Please see the attached Figure 3, About 36 inches of overburden will be pushed away from the mining
surface, which will have dimensions of 300' by 300', to expose the rock surface. The quarry will be mined
at a slope of 3:1, starting at the edge of the 300' by 300' square, to a depth of 12 feet below the exposed
rock surface. At twelve feet of depth, the surface will be mined flat.
It is estimated that approximately 50% of the mined material will be waste (with an expansion factor of up
[0 100%) and will be spread over the bottom of the pit and graded flat when mining is completed and will
raise the surface of the pit bottom by about six fee[. Then the overburden material will be pushed back over
the pit. This will create a flat, reasonably smooth, depression with 3:1 side slopes and a slope length of
about 20 feet from the edge of the unmined surface. Please see the cross section shown in the attached
Figure 3. Post mining use will be pastureland.
