DAVID FRIEDMAN Office of Solid Waste, Environmental Protection Agency, Washington, DC 20460 Background RCRA mandates the EPA to i d e n t i f y those residuals which, if improperly managed, pose a hazard to either human health or the environment. In implementing the Act, EPA has promulgated regulations i n Parts 260 through 270 of T i t l e 40 of the Code of Federal Regulations. Parts 260 and 261 e s t a b l i s h the conditions under which a material becomes a waste and i d e n t i f y those wastes which are "hazardous wastes" and must be managed according to the management standards of Parts 262 through 270. Pesticide-containing materials may be c l a s s i f i e d as wastes subject to RCRA if they have served t h e i r intended use and are sometimes discarded, i r r e s p e c t i v e of whether they are being disposed of or are destined for r e c y c l i n g . A waste i s a "hazardous waste" if i t exhibits any of the c h a r a c t e r i s t i c s of a hazardous waste, or i s l i s t e d i n sections 261.31, .32, or .33. Pesticide wastes that are hazardous by reason of the c h a r a c t e r i s t i c s are those which are e i t h e r : solvent based and have a flash point AND LOGS IN EXISTING PART Β FACILITY
