ete solidification or dewatering of wet wastes should be assured by the implementation of a process control program or by methods to detect free liquids within container contents prior to shipment. 1. Process Control Program a. Solidification (binding) agents and potential waste constituents should be tested and a set of process parameters (pH, ratio of waste to agent, etc.) established which provide boundary conditions within which reasonable assurance can be given that solidification will be complete, with essentially zero free liquid, and appropriate waste form characteristics. b. Dewatering procedures, equipment, and potential waste constituents should be tested and a set of process parameters (settling time, drain time, drying time, etc.) be established which provide boundary conditions within which reasonable assurance can be given that dewatering will be complete, with essentially zero free liquid. c. The solid waste processing system (or liquid waste processing system, as appropriate) should include appropriate instrumentation and wet waste sampling capability necessary to successfully implement and/or verify the process control program described in items B.II.1.a and/or B.II.1.b, above. d. The plant operator should provide assurance that the process is run within the parameters established under items B.II.1.a and/or B.II.1.b, above. Appropriate records should be maintained for individual batches showing conformance with the established parameters. 2. Free Liquid Detection Each container filled with solidified or dewatered wet wastes should be checked by suitable methods to verify the absence of free liquids if a process control program is not followed or an off-normal condition exists during processing. Visual inspection of the upper surface of the waste in the container is not alone sufficient to ensure that free water is not present in the container. Provisions to be used to verify the absence of free liquids should consider actual solidification
