                   Treatment Standards Proposed For
                   20 Newly Listed Hazardous Wastes
                   and Contaminated Debris

       Background

       The Hazardous and Solid Waste Amendments (HSWA) to the Resource
       Conservation and Recovery Act (RCRA) enacted in 1984 prohibit
       the land disposal of untreated hazardous wastes. HSWA requires
       EPA to set levels or methods of treatment for hazardous wastes to
       substantially diminish the short-term and long-term threats to human
       health and the environment.  Wastes that meet the treatment
       standards established by EPA may be land disposed (i.e., placed in a
       landfill, surface impoundment, waste pile, injection well, land
       treatment facility, salt dome formation, salt bed formation, or
       underground mine or cave).

       The statutory schedule for land disposal restriction (LDR) rules
       covered by HSWA was completed on May 8, 1990. However, a number
       of hazardous wastes have been newly listed or identified since 1984
       and LDR treatment standards must be promulgated for these wastes.

       Action

       EPA is proposing LDR treatment standards for 20 newly listed wastes
       that are based on identified best demonstrated available technologies
       for the treatment of these wastes. The 20 newly listed wastes are:

          • Recent petroleum refining wastes (F037 and F038)

          • Wastes from the production of unsymmetrical demethydrazine
            (K107-K110)

          • Wastes from the production of dinitrotoluene and toluenediamine
            (KlllandK112)

          • Wastes from the production of Ethylene Dibromide (Kl 17, Kl 18,
            and K136)

-------
   •  Wastes from the production of Ethylenebisdithiocarbamic
     acid (K123 - K126)

   •  Wastes from the production of Methyl Bromide (K131 and K132)

   •  Additional organic U wastes (U328, U353, and U359)

EPA is also proposing to amend the treatment standards for debris
contaminated with prohibited listed or prohibited characteristic
hazardous wastes.  Under the proposal, debris must be treated
 prior to land disposal using specific technologies from one or more
 of the following families of debris treatment technologies:  extraction,
destruction, or immobilization.  EPA is also proposing that
contaminated debris that is treated by extraction and destruction
technology and no longer exhibits a hazardous characteristic would
 no longer be subject to regulation  as a hazardous waste.

In addition, EPA is proposing revisions to a number of current LDR
treatment standards, including:  organic constituents of F001- F005
wastes: wastewaters for certain listed hazardous wastes, basing the
new treatments standards on actual wastewater treatment
technologies, rather than incineration scrubber waters;  alternate
treatment standards for K006 and K062 wastes and extending the
K061 generic exclusion to F006 and K062 wastes treated by high
temperature metal recovery: adding vanadium to Appendix VIII;
simplifmg notification and certification rules for characteristic wastes
and clarifying the status under the land disposal restriction program of
wastes that are listed due to being characteristicly hazardous. EPA is
also proposing to establish a new waste management unit known as a
containment building.
