<br /> <br />EXHIBIT E (Cont'd.) <br />' Seeding will be done between the last week of March and the <br /> first week of hiay. Seed will be drilled except where slopes <br /> exceed 3 to 1. On steeper slopes seed will be broadcast at <br /> twice the drill rate. The planned seed mixture is designed to <br />' be used without mulches or irrigation. hiulches would lower soil <br />' temperatures and maintain moisture better, but would also <br /> provide an environment more favorable for cool season grasses <br />' (unlike the predominant natives that occur in the area), cause <br /> nitrogen imbalances, require additional chemical fertilizers and <br /> possibly damage the soil microflora. <br /> The seed mixture recommended for the Pioneer Mine site is <br />' <br /> as follows: <br />t Species Rate (# P.L.S./Acre)* <br />Blue Grama 1.5 <br />t Sideoat Grama 3 <br />Western Wheatgrass 3 <br />Streambank Wheatgrass 2 <br />Little Bluestem 3 <br />' Fairway Crested Wheatgrass 2 <br />Cicer Milkvetch i <br />15.5 <br />' *Drilled rate at 33.12 P.L.S./ft.2. Double all rates, <br />except for Cicer !dilkvetch, if broadcast. <br />As a temporary stabilization measure for topsoil stockpiles <br />that are to remain for more than one year, the following mixture <br />' will be used: <br />1 <br /> <br />Species <br />Fairway Crested Wheatgrass <br />Russian Wildrye <br />Alfalfa <br />Broadcast Rate (#P.L.S./Acre <br />3 <br />3 <br />1 <br />7 <br />i1 <br />' 18 <br />
