Preparation of Hazardous Waste for Disposal

(1) The following processes shall not be deemed "treatment" of hazardous waste and shall not be subject to 310 CMR 30.500 through 30.999 if such processes are done at the site of generation of the waste and are done solely for the purpose of making the waste more amenable to disposal in a hazardous waste facility, provided that the accumulation, collection, transport, storage, treatment and disposal of such hazardous waste before and after such processes are done shall be subject to 310 CMR 30.000: (a) The addition of an absorbent (e.g., sawdust) in which a chemical reaction does not occur; and (b) The use of a gelation process or similar technique in which a chemical reaction does not occur. (2) 310 CMR 30.603(1) shall not apply to, and all applicable requirements of 310 CMR 30.000 shall apply to, solidification techniques which employ cement-based processes, pozzolanic processes, thermoplastic techniques, organic polymer processes, surface encapsulating techniques, glassification processes, or similar processes. (Note: For a description of the above-listed processes see Guide to the Disposal of Chemically Stabilized and Solidified Waste, U.S. Environmental Protection Agency, SW-872, September 1982.)
