The document supports the proposed rule for the Third Third of the wastes scheduled for restriction from land disposal under Section 3004(m) of RCRA. It presents the estimates of the quantities of wastes that will require alternative treatment and recovery prior to land disposal. It also presents estimates of alternative treatment and recovery capacity available to manage wastes restricted from land disposal, taking into account the demands already placed on that capacity by previous land disposal restrictions. Volume 2 presents the results of the analyses of required capacity for each alternative technology on a waste-specific basis for the wastes in the proposed Third Third rule.
