                    SECOND THIRD

       The 1984 Hazardous and Solid Waste Amendments (HSWA) to the
       Resource Conservation and Recovery Act (RCRA) prohibit the continued
       land disposal of untreated hazardous waste beyond specified dates,
       unless a petitioner demonstrates that the hazardous constituents will
       not migrate from the land disposal unit for as long as the waste
       remains hazardous. The amendments require the Environmental
       Protection Agency to: (1) rank all listed hazardous wastes so that
       wastes with high intrinsic hazard and volume would be restricted from
       land disposal first, and wastes with low intrinsic hazard and volume
       would be dealt with last; (2) separate the list of wastes into a schedule
       of thirds; and (3) set treatment standards for all hazardous wastes
       that will diminish the toxicity of the wastes or reduce the likelihood of
       the migration of their hazardous constituents.

       EPA met the August 8, 1988, deadline for promulgation of treatment
       standards for the First Third of the listed hazardous wastes.  The
       deadline for the Second Third of the listed hazardous wastes is June 8

       This rulemaking presents EPA's final approach to implementing the
       land disposal restrictions for the Second Third hazardous wastes.
       Specifically, for 34 Second Third hazardous wastes, this rule
       establishes treatment standards based on treatment performance of
       the Best Demonstrated Available Technology (BDAT) and specifies
       when those standards will be effective.

       Most of the treatment standards in this rule are expressed as
       concentrations measured in the treatment residues. As such, any
       technology not: otherwise prohibited (e.g., impermissable dilution) may
       be used to meet the treatment standards. In some cases, due to
       difficulties with analytical methods, a treatment method

 (incineration or carbon absorption) has been specified as the treatment

 EPA's approach to waste analysis requires using both total constituent
 concentration and extract from the Toxicity Characteristic Leaching
 Procedure measures of the performance achievable by BDAT.

 EPA is delaying the  effective date of the following cyanide-containing
 wastes until July 8, 1989: F006, F007.  F008, and F009 (electroplating
 wastes), and F011 and F012 (heat treating wastes). In addition, the
 Agency is, in effect,  establishing a bifurcated treatment standard for
 F011 and F012 wastes:  between July 8 and December 8,  1989, the
 treatment standard  is 590 mg/kg for total cyanide and 30 mg/kg for
 amenable cyanide: after December 8, 1989, it is 110 mg/kg for total cya-
 nide and 9.1 mg/kg for amenable cyanide. EPA is delaying these effec-
 tive dates to allow time for facilities to adjust existing cyanide treatment
 processes to operate more efficiently.

 Second Third wastes for which standards are not proposed will be sub-
ject to the "soft hammer" provisions of RCRA, which will allow continued
 land disposal until May 8, 1990, if certain conditions are met. In
 addition, this rule determines the treatment standards for 19 First Third
 wastes that are currently subject to the "soft hammer" provisions, 14
 Third TTiird wastes,  and 4 "Newly Listed" wastes. EPA is also promulga-
 ting prohibitions and effective dates for wastes that are currently being
 disposed of by means of underground injection.
