Hazardous Waste Management System; Testing and Monitoring Activities

The Environmental Protection Agency (EPA or Agency) is amending its hazardous waste regulations under subtitle C of the Resource Conservation and Recovery Act (RCRA) of 1976, as amended, for testing and monitoring activities. This amendment adds new and revised methods as Update II to the Third Edition of the EPA-approved test methods manual ``Test Methods for Evaluating Solid Waste, Physical/ Chemical Methods,'' EPA Publication SW-846. It also incorporates the SW-846 Third Edition, as amended by Updates I (promulgated August 31, 1993), II, and IIA (promulgated January 4, 1994 as part of the wood surface protection rule), into 40 CFR 260.11(a) for use in complying with the requirements of subtitle C of RCRA. The intent of this amendment is to provide better and more complete analytical technologies for RCRA-related testing and thus promote cost effectiveness and flexibility in choosing analytical test methods.
