Waste Management System; Testing and Monitoring Activities; Notice of Availability of Final Update V of SW-846

The Environmental Protection Agency (EPA or Agency) is providing notice of the availability of ``Final Update V'' to the Third Edition of the manual, ``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' EPA publication SW-846. Final Update V contains analytical methods, of which 8 are new and 15 are revised. The methods in Update V may be used in monitoring or complying with the Resource Conservation and Recovery Act (RCRA) hazardous waste regulations. This action includes revisions to the methods in response to comments received on a Notice published in the Federal Register on October 23, 2013 and finalizes the methods and guidance. In addition, the Agency is also finalizing revisions to Chapters One through Five of SW-846 and an Office of Resource Conservation and Recovery (ORCR) policy statement in the SW-846 methods compendium. The Agency is issuing this Update as guidance since the changes in this document to the SW-846 analytical methods are not required by RCRA's hazardous waste regulations. Any required analytical methods have not been changed.
