allations. 3.2.4 Construction Plans 3.2.4.1 Excavation and Engineering Modifications. Briefly discuss the design bases and construction plans required to enhance and improve the ability of the natural characteristics of the site to confine the waste after disposal. Using drawings as necessary, show the layout of the functional features of the burial facilities. 3.2.4.2 Waste Placement. Briefly describe the features of the burial facility that ensure placement of wastes with ease of operation, maximum utiliza- tion of space, and minimum deformation of waste packages and minimum potential subsidence of the disposal units. 3.2.4.3 Backfilling and Compaction. Briefly describe criteria, procedures, and methods that will be used to backfill and compact the fill and cover materials 12 during the operational phase. Include consideration of composition and specifi- cation of backfill, reconsolidation procedures, precautions to prevent water intrusion, thermal and radiological effects, waste or waste container interac- tions, and materials (e.g., clay) added to mitigate waste migration. 3.2.4.4 Trench Sealing and Use of Engineered Structures. Briefly describe measures to direct surface water away from disposal areas. Discuss any engineered methods or structures to be used to keep the possibility of infiltration of rain and surface water to a minimum. Describe water-proofing techniques to be used, including a discussion of the chemical and physical properties of materials selected. Include consideration of the thickness and types of cover to be used and the stabilization techniques to be used on the cover surface. 3.2.4.5 Site Drainage and Erosion (Operational and Postclosure). Briefly describe the drainage system and show how it will ensure efficient and rapid removal of precipitation waters and prevent flooding and erosion. Discuss surface treatment to be used to resist erosion and to prevent particulate releases via wind erosion. 3.3 Support Facilities 3.3.1 Types of
