The U.S. Environmental Protection Agency (EPA) is issuing a final decision not to list wastes generated from the use of 14 chemicals as solvents as hazardous under the Resource Conservation and Recovery Act (RCRA). The determinations in this rule are limited to specific solvent wastes. This rule is a determination only that the solvent wastes considered will not be added to the list of hazardous wastes and is not a determination that the underlying chemicals are nontoxic in all circumstances in which they are used or discarded.
