Fact Sheet
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.
