sal in accordance with applicable Federal regulations. 2. Wet Wastes a. Liquid wet wastes such as evaporator and reverse osmosis concentrates should be rendered immobile by combining with a suit- able binding agent (cement, asphalt, etc.) to form a homogeneous solid matrix (absent of free water) prior to offsite shipment. Adsorbents such as vermiculite are not acceptable substitutes for binding agents. b. Spent resins and filter sludges may, if acceptable to the receiving burial site, be shipped dewatered. These dewatered wastes are subject to (1) items B.II.1.b. and B.II.2. below, (2) to the receiving burial site maximum free liquid criteria (upon receipt at the burial site), and (3) applicable DOT regulations. Furthermore, the activity level of the dewatered wastes may, subject to receiving burial site requirements, dictate the type of container to be used. Solidification of spent resins and filter sludges in a suitable binder is also an acceptable alternative. c. Spent cartridge filter elements may be packaged in a shielded container with a suitable absorber such as vermiculite, although it would be desirable to solidify the elements in a suitable binder. 11.4-8 Rev. 2 - July 1981 II. ASSURANCE OF COMPLETE SOLIDIFICATION OR DEWATERING Complete 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,
