EPA proposed treatment standards for the newly identified organic toxicity characteristic wastes (except those managed in Clean Water Act (CWA) systems, CWA-equivalent systems, or Class I Safe Drinking Water Act (SDWA) injection wells), and treatment standards for all newly listed coke by-product and chlorotoluene production wastes that must be met before these wastes are land disposed. EPA also proposed to require ignitable characteristic wastes with a high total organic carbon (TOC) content and toxic characteristic pesticide wastes, that are being disposed in Class I nonhazardous waste injection wells, to either be injected into a well that is subject to a no-migration determination, or be treated to meet the land disposal restrictions treatment standards prior to injection.
