The above introducetl species, as <br />well as all natives in the mixes are compatible with the plant and animal species of the region and are <br />not poisonous or noxious. These species are desirable and necessary to the achievement of the • <br />approved postmining land use. The introduced species proposed have been developed for, or used <br />in, a variety of agronomic situations in the western U.S. for many years and are well documented in <br />the technical literature. <br />Seeding and Planting Methods Seeding of the permanent seed mixes will be done the first fall <br />planting season after topsoil distribution. At the Seneca II Mine five miles to the east, seeding has <br />been done as early as late August with no winter kill problems. This is due to the insulating affects of <br />heavy snow cover. Cover crops may be seeded at any time from late spring to the fall planting <br />season to provide interim stabilization as necessary. Seeding of perennial mixes in areas with cover <br />crops will be timed to avoid direct competition with actively growing cover crop species. Cover crops <br />that may produce seed that would compete with the perennial mix will be mowed prior to seed <br />maturation. The normal planting season will run from August 15 to approximately November 1. <br />Weather conditions may require earlier termination of the fall planting season. Spring weather <br />conditions severely limit the opportunities for seeding of the permanent mixes. The month of May will <br />be the only consistent period available for spring seeding. All spring seeding activities will be <br />completed by June 1. Any transplanting, interseeding, or reseeding of permanent reclamation would <br />usually be accomplished <br />C~ <br />28 Revised 7/99 <br />
