Describes a method for evaluating post-closure care performance—a systematic and hierarchical evaluation of leachate, landfill gas, groundwater, and the final cap—based on criteria established for a defined end-use strategy.

This document focuses on the decisions and facilitating the decision processes related to design, evaluation, construction, and monitoring associated with bioreactor landfills.

Focuses on the decisions and facilitating the decision processes related to design, evaluation, construction, and post-closure care associated with alternative final covers.

Presents examples of flexibility used in regulatory frameworks for approving alternative landfill cover designs, current research information about the use of alternative covers, and examples of approved designs and constructed covers.
