The Environmental Protection Agency is today announcing a change in the Agency's interpretation of its rule that lists wastes from carbamate production as hazardous wastes under the Resource Conservation and Recovery Act (RCRA). Under this new interpretation, wastes from the production of non-carbamate intermediates that are used exclusively in the production of carbamates but are not produced at the ultimate site of manufacture of the carbamates will not be subject to the rule. These wastes are among those given the RCRA waste code designations K-156 and K-157 in the rule.
