United States Office of Solid Waste CDACo« coo Environmental Protection and Emergency Response E. °Z« Agency (OS-305) May1993 Office of Solid Waste &EPA Environmental 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. ------- United States Office of Solid Waste CDAC™ c oo Environmental Protection and Emergency Response E.A53™ Agency (OS-305) May 1993 Office of Solid Waste c/EPA Environmental Fact Sheet EPA Issues New Treatment Standards For Certain Ignitable and Corrosive Wastes EPA is replacing the treatment standard of deactivation for certain ign'rtable and corrosive wastes with new standards that include numerical treatment standards for the hazardous constituents present in these wastes.
