... ith a landfill disposal capacity of approximately 510,000 yd 3 . The ICDF Complex is designed and authorized to accept INL CERCLA-generated waste and includes the necessary subsystems and support facilities to provide a complete waste management system. The ICDF Complex comprises the landfill, evaporation pond (two cells), leachate collection system, staging and storage areas, decontamination facility, administrative facility, and other systems necessary for operations. This O&M Plan presents the operational approach and requirements for operating the various systems/components that are a part of the ICDF. Appendix A to this O&M Plan presents detailed procedure overviews describing key operational procedures used at the ICDF Complex. Each procedure overview is numbered to align with the corresponding section of the O&M Plan and will continue to be used to develop detailed operating procedures for the ICDF Complex. Appendix B to this O&M Plan identifies the anticipated equipment needs for ICDF operations. This O&M Plan presents the planned operational process based upon an evaluation of the remedial action requirements set forth in the Final Record of Decision, Idaho Nuclear Technology and Engineering Center, Operable Unit 3-13.
