Geosyntec Consultants (2006b) as described in Section C2 of Appendix C, provide a technically defensible approach for deciding when discontinuation of care activities can occur. Both require a demonstration that safe conditions exist before a landfill can exit permitted post-closure care. Active operation Closure Active Post-Closure Care Minimal/No Regulatory Based Care Required An important component of the future of the managed landfill is use of proactive operational practices to enhance waste degradation and move quickly to reduce long-term impact potential. ”Wet” or bioreactor landfills designed and operated to enhance waste degradation through active treatment promise more sustainable landfill technology. These landfills provide the additional benefit of offering a wider range of reuse options for the property. This is discussed in terms of different landfill design types in Section 6.3 and more broadly in Section 7.4. 6.3 Environmentally Protective Landfill Designs Different types of modern performance-based landfill designs all feature integrated operational control systems to provide containment, environmental performance monitoring and data assessment, and rapid response to system upsets. Although each landfill features control systems appropriate to the particular site, most modern landfill designs can be categorized into one of the four main types, as outlined in Table 6-1. The key attributes and environmentally protective features of each of these four types of modern landfill designs listed in Table 6-1 are outlined in the remainder of this section using a series of five Tables 6-2 through 6-6. Table 6-0 provides an at-a-glance summary of the purpose of Tables 6-1 through 6-6. It is important to note, however, that this reference tool is provided as an example only and is not exhaustive; a number of variants on these four main types of landfills exist. The links to tables listed in Table 6-0 are intended to serve as quick cross-references to highlight how each landfill type provides the key attributes of modern landfills (i.e., containment, operations, waste treatment, maintenance, and monitoring) to protect the four main environmental media (i.e., groundwater, surface water, the vadose zone, and air). As previously discussed, no single attribute is the key to protection of human health and the environment for a specific design; it is the integration of design, component systems, operation and maintenance, and environmental performance monitoring that provides overlapping levels of environmental protection.
