6) Please provide damage waivers or agreements with Excel Energy and Western Slope
Gas for the installation of (5) 4' culverts through the identified easements for water
pass through from Lakes 2 & 3 to Lake 1 per Rule 6.4.19(c).
7) Mining Map, C -2 shows 2 culverts between Mining Area 1 and Mining Area 3.
These culverts are not shown on Map F, The Reclamation Map. Staff cannot
identify in the text where and when these will be removed. Please Clarify if the
culverts are to remain or be removed.
8) Please identify on Map C -2, the exact location of the proposed dike cut, back to the
original drainage, in the Area 1 Lake. Also address erosion control and construction
details for this structure.
9) The Mining Plan states that Lake 1 or 2 will be temporarily drained to facilitate the
construction of industrial pads. Water from the drainage project will be pumped into
the constructed sedimentation pond. Please clarify that outflows and inflows will be
balanced since it is obvious that there is not enough capacity in the sediment pond
for water from either lake.
10) Please specify if explosives will or will not be used per Rule 3.4.4(1).
11) Exhibit E, The Reclamation Plan states a volume of 90,088cy of topsoil is
required to cover 83.76 acres. Staff's calculation of 83.76 X 43560 / 27 X .75 (8"
cover) = 101,350 CY. Please clarify the difference of 11,261.6 CY of topsoil.
12) The seed mix for the reclaimed wetland / slope areas do not contain any
shrubs or trees. Please clarify the justification for this or add in some compatible
woody species for wetlands / wildlife benefit.
13) The Mining of Area 5 will require the movement of topsoil and overburden to
other areas. It is understood that some will be used to construct other pads in other
areas. However, where will excess topsoil /overburden be stored, once these other
areas are constructed, for Area 5 reclamation? Please clarify and note on Mining
Maps if necessary.
14) The Mining Plan states that Areas 1,2 or 3 will be used as a processing area
during mining of Area 5. If these areas are already reclaimed is it the operator's
intent to re- disturb these areas? If these areas are not reclaimed or re- disturbed,
then the cost for reclamation should be reflected in the "worse case" as additional
reseeding areas. Please clarify. Staff will need to know approximate surface area
for processing area for bond calculations.
15) Please supply documentation of an agreement with Grand Junction Drainage
District concerning the relocation and disturbance of their irrigation return canal
system per Rule 6.4.1 9(a).
16) The Geotechnical Stability Exhibit states that a 30' buffer will be maintained
around the permit boundary line. Please clarify if this pertains to all easements
within the boundary as well.
17) Enclosed is a copy of the State Engineer's "conditions for approval ". Please
address the concerns of this Office.
