The EPA announced that new restrictions should be placed on carbamate wastes.

The EPA has proposed revising 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 be treated to 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, the agency has proposed an alternative and would require the use of the best demonstrated available technologies (BDAT) for treating these wastes. In addition, this action proposes to remove the carbamate Regulated Constituents from the table of Universal Treatment Standards.

Carbamates are typically used in insecticides (such as the commercially named Furadan and Sevin), polyurethanes and medicines. For more information, read the entire Federal Register announcement.
