We maintain several permits to govern cleanup operations at Hanford, but the primary permit is the Hanford dangerous waste (site-wide) permit. Or, across most of Hanford, known simply as "The Permit." The site-wide permit has been comprehensively revised several times. Currently we're operating with Revision 8C, but we are working toward release of Revision 9.
In addition, we administer individual permits for facilities that handle mixed (radioactive and hazardous chemical) waste in Washington.
