November 23, 1999 • • (14)(e) The acid or base potential of soils is not anticipated to be excessively high, and no metal leaching from any exposed materials is anticipated. Reclamation of the site after operations is fully expected to achieve the post -mine land use. (15) Construction Schedule Information (15)(a) Facilities designed to transport designated chemicals will be constructed in the second quarter of 2000. (15)(b) No potential for acid mine drainage exists on the site. (16) Quality Assurance and Quality Control Environmental protection facilities will be designed by professional engineer(s). All construction quality control will be done by representatives of the design engineer(s). Design engineers must document that the facilities are constructed to their specifications before submitting the constructed facilities to the owner for operation. (17) Plant Growth Medium (Soils) (17)(a) A soil survey map and narrative delineating the soil mapping units and providing standard soil parameters from the Soil Conservation Service (National Resource Conservation Service -NRCS) was submitted in Exhibit E of the Application. (17)(b) The above information was obtained from the NRCS and was based on previous site specific work conducted by the NRCS. (17)(c) Soils data are presented in Table I -2 and Exhibit I in the Application. In certain locations on the Rock School Lease, notably the production well field area, topsoil is thin, and extreme care will be taken in salvaging sufficient plant growth medium to achieve proper reclamation. When stockpiled plant growth medium is used for reclamation, the medium will be tested for requirements for any amendments, and the proper amendments will be added. This procedure is described in the Reclamation Plan, submitted as Exhibit E in the Application. (18) Wildlife Protection (18)(a) The BLM requires wildlife mitigation on the Rock School Sodium Lease, and AmerAlia is committed to working with the Colorado Division of Wildlife and the Bureau of Land Management in mitigating wildlife impacts. Specific mitigation measures will be determined based upon consultations with those two agencies. (18)(b) Designated chemicals will not be routinely available to wildlife on the Project. The only potential contact facility would be the well field drainage pond which may contain mining solution for short periods of time during pipeline draindown. The pond will be fenced to exclude large mammals. The pond may also be replaced with a tank as stated in the Responses to DMG Comments letter of November 23, 1999. 7 AmerAlia, Inc.
