Title: Response to Petition for Site-Specific Variance for Elemental Mercury Wastes (D009 and U151) Under the Land Disposal Restrictions 
Abstract:

EPA is considering establishing an alternative treatment standard for high-concentration mercury wastes. The Agency is reviewing Republic Services’ petition for a Land Disposal Restrictions (LDR) treatment variance that would allow it to stabilize elemental mercury extracted from high-level mercury-containing wastes through a process of conversion to mercuric sulfide followed by double encapsulation and monofill disposal. To approve the petition, EPA will go through a notice and comment process and issue a variance from the LDR regulations.
