Chrome-bearing hazardous waste

HSWA (Hazardous and Solid Waste Amendments) established statutory deadlines for prohibition of land disposal of three categories of waste which EPA has labeled the first-third, second-third, and third-third. Effective November 8, 1986, the statute prohibits the land disposal (except by deep-well injection) of dioxin-containing hazardous wastes and solvent-containing hazardous wastes (first-third rule wastes). Effective July 8, 1987, the statue prohibits disposal (except deep-well injection) for the second-third listing of hazardous wastes, called the California list. The third-third listing of hazardous wastes includes other scheduled and newly identified wastes considered hazardous under 400 CFR, 268.12. Third-third wastes can be disposed if respective treatment standards established by EPA are met. The focus of this paper is one particular waste on the third-third list, that is, land disposal restrictions for D007 chrome waste. The 200-plus page Final Rule for third-third waste was approved by EPA May 8, 1990, and was published in the June 1, 1990, Federal Register.
