<br />RECLAMATION PLAN NOTES AND RESTRICTIONS
<br />All final slopes shall be a maximum steepness of 3H:IV. A minimum of 6'
<br />of topsoil shall be placed on all slopes and any other disturbed and
<br />reconstructed areas above the existing water level,
<br />1, Any hardpacked areas shall be scarified prior to replacement of
<br />topsoil and seeding. After backfllling, grading of any area to final
<br />slopes and placement of topsoil, seeding will be initiated as soon as
<br />possible.
<br />2. Except for wetland establishment areas, the below grass drill seed mix
<br />below shall be used for re- seeding of slopes and disturbed areas, For
<br />broadcast seeding, the rate shall be doubled. Mulch shall consist of
<br />4,000 lbs. /acre weed free native grass crimped Into the soli surfaces.
<br />Planting shall occur between November 1 and April 30 when the ground is
<br />Frozen and be planted 1/4 to 3./4 Inches deep In 7' to 12' rows,
<br />Non - Irrigated grass planting of the non - wetland areas shall consist of
<br />the following:
<br />SPECIES VARIETY PLS4 'L PLS #/AC
<br />Western wheatgrass 'Arrlba or Barton' B.0 30 2.4
<br />Pubescent Wheatgrass 'Luna' 9.0 20 1.8
<br />Sideoats grama 'Vaughn or Butte' 4,5 30 1.4
<br />Blue grama 'Hachlta or Lovington' 1.5 10 0.2
<br />3. For wetlands creation, partial reclamation will begin with the
<br />backfllling of sediments created during the processing of the mined sand
<br />and gravel. At the termination of mining, at least 50% of the presently
<br />exposed lake area Is expected to been backfllled to a level to support
<br />wetland vegetation at the conclusion of all mining. Interim planting of
<br />wetlands vegetation shall be undertaken, whenever a minimum of 5 acres
<br />has been filled to within 3' to 5' above the original lake surface.
<br />Wetland planting shall first consist of broadcast seeding of the below
<br />or similar grass seed mix at an application rate of 20 lbs. /acre during
<br />the growing season (May through August):

<br />4. Per the Noxious Weed Control Plan in EXHIBIT D - MINING PLAN, noxious
<br />weeds will be controlled, particularly Diffuse Knapweed, Scotch Thistle,
<br />and Canada Thistle, which have been observed within the permit area and
<br />on adjacent property. All areas adjacent to roadways and waterways will
<br />be assessed every spring to determine the best management practice for
<br />weed control, At a minimum, all noxious weed areas will be mowed as
<br />needed, In heavily Invested areas, approved herbicides will be applied as
<br />needed to Include, but not limited to, Tordon 22K applied at 1 pt /ac at
<br />20 gpa or 2,4 -D 44 amine at 1 qt /ac at 20 gpa. Consultation with
<br />qualified vegetation managers and /or county weed control coordinators
<br />will be on -going to assist in the management of noxious weeds.
<br />5. Final amount of wetlands area expanded to vary from 50 to 75 percent
