<br />RECLAMATION PLAN NOTES AND RESTRICTIONS - Phase 6A 8 6B
<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 scarlfled prior to replacement of
<br />topsoil and seeding. After backfIIIIng, 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 l as. /acre weed free native grass crimped Into the soil 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 PLS# % PLS # /AC
<br />Western wheatgrass 'Arriba or Barton' 8.0 30 2.4
<br />Pubescent Wheatgrass 'Luna' 9.0 20 1.8

<br />3. For wetlands creation, partial reclamation wlIt 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 backFI(Ied 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 6' above the original lake surface. Wetland planting
<br />shall first consist Of broadcast seeding of the below or similar grass
<br />seed mix at an application rate of 20 lbs. /acre during the growing season
<br />(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 herblcldes will be applied as
<br />needed to include, but not limited to, Tordon 22K applied at I pt /ac at
<br />20 gpa or 2,4 -D 4# 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 expected to be a minimum of 25t acres
