||Best demonstrated and available technology (BDAT) background document for wastes from the production of dinitrotoluene, toluenediamine, and toluene diisocyanate, K027, K111-K116, U221, U223 : proposed.
The document provides the background for EPA's rationale and technical support for the proposed treatment standards for the listed wastes identified in 40 C.F.R. 261.31 as K027, K113, K114, K115, K116, U221, and U223. K027, which is generated from the production of toluene diisocyanate (TDI), is part of the 2nd third of the scheduled listed wastes to be evaluated by the Agency for land disposal restrictions. Wastes listed as K111, K112, K113, K114, K115, and K116, which are generated from the production of dinitrotoluene (DNT), toluenediamine (TDA), or toluene diisocyanate (TDI), are 'newly listed' (i.e., listed after the effective date of HSWA). Treatment standards for K113-K116 are being proposed as part of this 2nd third's rulemaking. The Agency is not proposing treatment standards for the newly listed wastes K111 and K112 at this time. In addition, the Agency is proposing treatment standards for soft-hammered 1st third U wastes, U221 & U223. This proposed regulation also addresses K027, K113-K116, U221, and U223 wastewaters generated from RCRA corrective actions and CERCLA remedial orders (as either contaminated ground or surface water).
