The quantity of seed applied on-the-ground will be determined on a Pure <br />Live Seed (PLS) basis, PLS being defined as "tested purity rate" x "tested <br />rate of germination." For example, the quantity of western wheatgrass <br />seed (95 percent purity, 10 percent germination) needed to meet a <br />stipulated 1.0 pound PLS/acre application rate: <br />Actual applied seed rate = required PLS rate (lb per acre) / PLS index = <br />1.0 lb per acre / 0.9 x 0.70 = 1.5 Lb per acre <br />15. Site-adapted, testecl seed for the current year is required and is subject <br />to the approval of the authorized officer (copies of the seed labels will <br />be furnished to the authorized officer). <br />16. Specific cultural practices that promote the establishment and survival of <br />seeded forbs and shrubs will be employed where practicable, subject to the <br />approval of the authorized officer. <br />17. On-site burial of concrete or asphalt at the time of sodium mine site <br />decommissioning is subject to prior approval of the authorized officer. <br />13 <br />
