                     EPA Issues New Treatment Standards
                     For Certain Ignitable and Corrosive
                     Wastes
                     EPA is replacing the treatment standard of deactivation for certain
                     ignitable and corrosive wastes with new standards that include numerical
                     treatment standards for the hazardous constituents present in these
                     wastes.
        Background
        In the 1984 Hazardous and Solid Waste Amendments (HSWA) to the
        Resource Conservation and Recovery Act (RCRA), Congress instructed
        EPA to ban untreated wastes from land disposal because it was
        concerned about improper land disposal practices and about the high
        volume of hazardous waste being land disposed.  EPA had to establish
        treatment standards for all hazardous wastes destined for land
        disposal which substantially reduces the toxicity or mobility of the
        hazardous constituents in the waste.

        On May 8, 1990, EPA finalized land disposal restrictions (LDRs) for
        ignitable, corrosive, and reactive (ICR) wastes. The rule  established a
        treatment standard of "deactivation," which requires removal of the
        hazardous characteristic through any type of treatment, including
        dilution. The rule did not require treatment of any hazardous
        constituents that might be present in ICR wastes.

        To ensure successful integration of the LDR program with the Clean
        Water Act (CWA) and the Safe Drinking Water Act's Underground
        Injection Control (UIC) program, special dilution provisions were
        established. These provisions included allowing aggregation of
        hazardous ICR wastes with nonhazardous wastes (dilution) in
        treatment systems regulated under the CWA, and allowing ICR wastes
        which, through deactivation, no longer exhibit the characteristic at the
        point of disposal to be deep well injected under the UIC  program.
