RCRA information pamphlet for laboratory managers This nine-page pamphlet will help those who generate laboratory wastes determine their responsibilities for disposing of them under forthcoming regulations of the Resource Conservation and Recovery Act of 1976 (RCRA). The pamphlet takes into consideration the unique nature of a laboratory environment and points out that wastes generated in laboratories can differ significantly from wastes generated at industrial production sites. Laboratories produce a variety of wastes, often in very small quantities, whereas industrial processes produce more uniform wastes. Proper handling and disposal of these wastes may require different procedures. One section, entitled "The Hazardous Waste Management System," includes a definition of the term laboratory. Another section tells how to determine whether a waste is hazardous, using various tests of ignitability, corrosivity, reactivity, and toxicity. A third section, "Generator's Responsibilities," includes information about wastes excluded from RCRA hazardous waste controls. The remaining two sections discuss transporting, treatment, and disposal. Also given is a table of state agencies and telephone numbers for the entire U.S. The first copy is free; additional copies cost $1 each. Write direct: Kathleen A. Ream, Manager, Federal Regulatory Programs, American Chemical Society, 1155 16th St., N.W., Washington, D.C. 20036.
