The Environmental Protection Agency (EPA or the Agency) is issuing a Direct Final Rule to revise the Land Disposal Restrictions (LDR) treatment standards for hazardous wastes from the production of carbamates and carbamate commercial chemical products, off- specification or manufacturing chemical intermediates and container residues that become hazardous wastes when they are discarded or intended to be discarded. Currently, under the LDR program, most carbamate wastes must meet numeric concentration limits before they can be land disposed. However, the lack of readily available analytical standards makes it difficult to measure whether the numeric LDR concentration limits have been met. Therefore, we are providing as an alternative standard the use of the best demonstrated available technologies (BDAT) for treating these wastes. In addition, this action removes carbamate Regulated Constituents from the table of Universal Treatment Standards.
