-I5- In the case of drill seeding, the seeder is followed by a chain drag which covers the seed. Broadcasted seed is covered with soil using a chain harrow or similar implement. Item: Fertilizing. Response: On page 5 of the Amendment, fertilizer application procedures are explained. All seeded slopes will be fertilized as suggested by the review comments, i.e., fertilizer will be added separately from seed application to avoid exposing seed to direct contact with fertilizer. This procedure provides for seed coverage and slow release of the fertilizer with precipitation. The Annual Reports document success with various fertilizer applications. The only topsoiled area is on the 10800 level. All other work has been performed on subsoil. Thus the results are directly applicable to the reclamation plan. Additional fertilization needs may be assessed by the plant inspection that will occur during reclamation activities. Item: Mulch on 2:1 slopes. Response: Hydromulch will be used on 2:1 slopes as was previously noted in response to the question regarding seed application. Item: Grass-shrub mixture and uptake of radionuclides. Response: The site-specific mixture of grasses and shrubs is to be determined upon completion of the reclamation plot work currently being conducted with the SCS. Planting was completed at the shrub plot this summer. As discussed in Supplemental Report S-4, plants are not known to be concentrators of uranium or its daughters. R.G. Menzel ("Radioactivity Uptake in Plants," p. 43-97, Proceedin s of the National Conference on Dis osal of Residues on Land, September 13-1 19 c asst ies uranium and ea in a "strongly excluded" (from concentration) group and radium as in the "not concentrated" group. Thorium is also considered to be "strongly excluded." Item: Pond Slopes. Response: The South Pit lake is designed to provide water for wildlife and to reduce the potential impact of peak flows in drainage channels located immediately downstream of the South Pit. In the Technical Revision to the Pitch Project permit submitted on June 9, 1982, and which was subsequently approved, the same general configuration for a pond was shown. Portions of the slopes of that pond, in areas where the pit walls were steeper, were on the order of 1.6:1. The application for the permit submitted in 1977 showed a similar lake in the North Pit. The applications have consistantly recognized the need to provide access to such a pond. The access is provided along the ramp that enters the pond from the north, and in the spillway area on the southwest. The slopes beneath the anticipated water level will be cut slopes, not fill slopes; and will therefore be relatively stable. The steeper slopes are aligned with the steeper portions of the South Pit.
