Title: ●Land Disposal Restrictions: Revision of the Treatment Standard for Carbamates 
Abstract: The Environmental Protection Agency is considering revising the Land Disposal Restrictions (LDR) treatment standards for hazardous wastes from the production of carbamates and carbamate commercial chemical products that become hazardous wastes when they are discarded or intended to be discarded. There may be no analytical standards available with which to measure compliance with the LDR requirements. An analytical standard is a reference material with a known concentration of a target chemical that is used to calibrate analytical instruments in order to confirm detection and quantification of that chemical. Currently under the LDR program, most carbamate wastes must be treated to meet numeric concentration limits before the wastes can be land disposed. The lack of analytical standards makes it impossible to measure whether the numeric concentration limits have been met. Therefore, we are considering providing as an alternative standard the use of the best demonstrated available technologies for treating these wastes. This will provide significant treatment to minimize threats to human health and the environment while avoiding the problems that result from the lack of analytical standards to determine if the numeric concentration limits have been met. In addition, we are considering removing hazardous carbamate wastes from the table of Universal Treatment Standards at 40 CFR 268.48. By doing so, these wastes would not be classified as underlying hazardous constituents that require treatment to meet numeric concentration limits in wastes that display the characteristic of ignitability, reactivity, corrosivity or toxicity at the point of generation. This overall action would allow hazardous waste management facilities to certify that wastes have been treated in compliance with applicable LDR requirements. These facilities face potential curtailment of operations when they are unable to demonstrate waste and treatment residual content through analytical testing.
