This Guide provides a beneficial, acceptable use framework for the development of: (1) Inactive and pre-RCRA (or pre-regulatory) solid waste landfills that are considered orphan or latchkey to be repurposed, despite having offsite migration impacts of landfill gases and/or leachate, albeit at de minimis levels; (2) other types of unregulated waste landfills; (3) sites impacted by chemical releases; (4) legacy or ongoing, intentional, or unintentional fill placement; (5) closed, open, or operating post-RCRA landfills or landfills in the planning stages such that materials may be placed in ways that optimize a landfills use in future years; and (6) under-utilized or heavily used (e.g., pedestrian; recreational; or repetitive, entertainment, single event) chemically impacted sites. Also, this Guide identifies land usage and conditions of adjacent/non-waste portions of a landfill (i.e., buffer areas not within the footprint of an actual landfill or chemically impacted site itself) that should be evaluated before a site use is considered acceptable.
Over the last half-century, environmental protection programs have withdrawn from use properties posing significant adverse human health impacts, yet some with lesser potential impact continue to be heavily used [e.g., pedestrian; recreational; or outdoor entertainment-related, concert audience seating] without evaluation. Assessment of environmental conditions for properties undergoing ownership transfer is now common (and often required), yet those of historic ownership are not similarly evaluated. This Guide serves the need for a forward-looking program that allows a knowledgeable environmental professional to complete an evaluation of a proposed beneficial use, utilizing readily available information and her/his professional judgment whether property usage restrictions are necessary to be protective of human health. Two outcomes of such an evaluation include finding that the proposed beneficial use is acceptable, or a finding that the proposed beneficial use request is not acceptable. The environmental professional may condition her/his finding of acceptability of beneficial use with institutional and engineering controls based on actual or potential soil chemical concentrations, known background chemical concentrations, and other approaches that provide a barrier between a chemical and a site user or limit times of use.
