CC-94-052: Universal Treatment Standards for the LDR Program and Treatment Standards for Newly Identified Hazardous Wastes

Enclosed please find material that appeared in the Federal Register on September 19, 1994. In it EPA finalizes a set of Universal Treatment Standards (UTSs) that must be met before a hazardous waste can be land-disposed (including placement in a surface impoundment). This final rule also contains treatment standards for the "newly identified" hazardous wastes (those that are hazardous because they exceed the threshold concentrations that apply to the Toxicity Characteristic Leaching Procedure).
