May Day and Idaho Mine Complex 112 (d) Permit Application <br />6.4.5(2)(f)(iii) Fertilization <br />Irrigation and soil amendments will not be applied to reclaimed areas not specifically identified within the <br />affected lands. Soil tests will be conducted before seeding if deemed necessary to confirm fertilizers type <br />and quantity. It is not anticipated that any soil amendments other than nitrogen will be required at the <br />time of planting. Nitrogen fertilization may be required within the first 2 years of revegetation efforts <br />(Rule 6.3.4 (1) (c)) and will be verified prior to final seeding or transplanting. <br />On steep areas greater than 2(Horizontal): I (Vertical), erosion control blankets may be used in conjunction <br />with seeding if the downslope area is vulnerable (such as the augmentation pond) or the season of com- <br />pletion may result in the area remaining bare through the winter and spring snow melt. Instead, mulching <br />or a suitable alternative could be used per requirements of the USDA. Other graded areas will be <br />mulched with 4,000 lb /acre of certified weed -free native grass, hay or straw. <br />6.4.5(2)(f)(iv) Revegetation (transplanting) <br />The tree and shrub species identified in Table E -3 will be transplanted in appropriate revegetation areas. <br />This will be the exploration drill pads and the graded slopes of Operational Areas particularly former <br />benches and the augmentation pond. Shrub species may be substituted with similar species native and <br />abundant to the site. The plants will be purchased from a commercial nursery in quart sized containers. <br />Individual plants would be placed on approximately 10 foot centers, resulting in 360 plantings per acre of <br />a mixture of all transplanted species. Although spaced apart to avoid crowding of individual plants, <br />transplants should not be evenly spaced in a regular pattern. Regular patterns do not mimic the surround- <br />ing vegetation and are not conducive to survival of the transplants. Tree species should be spaced wider <br />from each other to account for their mature size. However, shrub species may be clumped closer together <br />and closer to the transplanted trees. <br />During the first two to four years, seeded grass plants will often out complete small containerized trees <br />and shrubs. Therefore, seed should not be spread adjacent to (within approximately 2 feet) transplanted <br />trees and shrubs. Trees and shrubs should be transplanted prior to seeding. <br />Table E -3.
