Deployment Area Selection and Land Withdrawal/Acquisition. M-X/MPS (M-X/Multiple Protective Shelter) Environmental Technical Report. Construction

摘要

The M-X system would directly affect the area in which it is constructed and cause many indirect impacts on the environment. To evaluate these indirect impacts, it is necessary to determine specifically what the construction effects are, and when, where, and to what extent they occur. This report identifies the environmental effects caused directly by construction of the system. Indirect environmental impacts are described in the FEIS and detailed in other ETRs. Major effects due to construction are the requirements for land, water, materials, and personnel, as well as the location, timing, and magnitude of each of these resource requirements. The proposed and alternative systems are described in Section 2 of this ETR. Section 3 describes, in more detail, each of the individual components which must be constructed. The sequencing of construction of the various parts of the system is contained in Section 4. Section 5 describes the method of construction of each of the components. The impacts and their possible mitigations are discussed in Section 6. The overall project effects, evaluated in terms of land and material resources required, are similar for each of the alternatives. Appendices A through E present a system layout, a construction plan and schedule, and a breakdown of the construction resources for the Proposed Action and each alternative. Appendix F presents a discussion of the latest design of the M-X system facilities as it relates to the Proposed Action, and compares this latest design to that used in this FEIS for analysis. Appendix G presents the background and documentation for the construction manpower estimates made by Task Force I and Task Force II.
