• Revegeta Lion <br />Seeding and Planting. <br />A total of 25.9 acres were permanently seeded in the south mine block, 'A• pit area, of the <br />Seneca II-W Mine in 1995. Seedings included 25.9 acres seeded with Seed Mix No. 1 - Upland <br />Sites and Ephemeral Drainages and supplemented with additional forb and shrub seed (Table <br />95.3). There were no permanent revegetacion activities in [he north mine block. Seeded <br />areas are shown on Exhibit 95.2. The area which received topsoil from pile N was disced <br />prior to seeding. Seeding was completed with a Laird rangeland type drill seeder. All <br />permanent seedinge were comple [ed in late Sep [ember and early October. <br />Shrub seedling planting. <br />During September 1995. 1000 Serviceberry, 1000 Chokecherry, and 450 Scrub oak seedlings <br />were planted in shrub plot 95-1 2-W. Bitterroot Native Growers of Corvallis, MT grew these <br />seedlings from seed collected a[ Seneca Mine. The seedlings were B to 10 inches in height. <br />The shrub plot was treated with OUST herbicide to restrict the emergence of annual plants <br />• which compete with the newly transplanted shrubs Eor nutrients and water. The OUST was <br />applied at 3 ounces per acre with a boom spray rig two weeks prior to out planting of the <br />seedlings. This plot is located northeast of the live shrub clumps and near the center of <br />•A• pit reclaimed area. ISee Exhibit 95.3 for seeded area and shrub plots locations). No <br />mulching activities were conducted during 1995. <br />Monitoring. <br />Revegeta [ion monitoring was conducted at the Seneca II-W mine on the area seeded in 1993. <br />See 1995 Seneca II and II-W Revegetation Monitoring Report, ESCO, Inc. <br />Weed Control. <br />Survey of noxious weeds was carried out on the mine permit area during the 1995 Eield <br />season.

The applied herbicide consisted of a tank mix of 2.5 gallons of 22R Tordon <br />and 2.5 gallons of 2,4,-D with 250 gallons of water. A spot spray gun was used [o <br />concentrate control activities on target areas. See Exhibit 95.4 for locations of areas <br />• treated with [his herbicide during May 1995.
