• season. Peabody will continue [o selvage, store, and replace soil as described and <br />approved in Permit C-80-005. Peebody~s soil scientist and reclamation supervisor will <br />continue to closely monitor soil handling activities at Seneca II, verifying that scraper <br />operators ere salvaging ell viable soil materials end redistributing soil at the specified <br />thickness. <br />Revegetation. Revegetation activities in 1990 included temporary and permanent <br />revegetation of disturbance areas et the Seneca [I Mine. Only permanently seeded areas <br />are shown on Exhibit 90.2, 1990 Seeding, Planting, and Noxious Weed Control Locations. <br />Temporary revegetation using Seed Mix p3 (page 13-19 of Tab 13) was Completed at topsoil <br />stockpile P. Seed Mix #3 was drill seeded at the specified rate. <br />Permanent seeding was competed on 87.1 acres in [he Yolf Creek and Yadge mining areas, in <br />the vicinity of the landfill, on reclaimed portions of haul road Eb, and at all recently <br />constructed stock ponds. There were no seedbed preparation operations Conducted prior to <br />permanent seeding in order to maintain the viability of establishing native species in <br />replaced topsoil materials. Seed Mix # 1 with supplemental species, presented in Table <br />• 3, was submitted to the Division for review on April 5, 1990 and was approved on May 18, <br />1990. Seed Mix p 1 was used for all permanent seeding conducted et the Seneca II Nine in <br />1990. <br />No mulching activities were conducted during 1990. However, all permanently revegetated <br />areas were cover cropped with barley in the spring and winter wheat in the fall at en <br />approximate drilled rate of 15 pounds per acre. <br />A total of 11,081 seedlings were planted in six concentrated shrub planting areas in 1990 <br />(See Exhibit 90.2 for locations). Table 4 lists the species planted end total numbers <br />planted for each species by area. All plant materiels were one year old stock developed <br />from regional native sources. The seedlings were grown and planted by Bitterroot Native <br />Growers, Inc. of Hamilton, Montana. Plantings vere completed in the fall of 1990 in <br />unseeded strips within the six reclaimed areas. Deer-Away repellent wos placed on <br />approximately one half of the planted seedlings. Initial late fall observations indicate <br />that this repellent may be effective in reducing browse damage following planting. <br /> <br />4 <br />
