The Environmental Protection Agency (EPA) is establishing best demonstrated available technology (BDAT) treatment standards for the listed waste identified in 40 CFR 261.32 as K046 (wastewater treatment sludges from the manufacturing, formulation, and loading of lead-based initiating compounds). If the treatment standards presented in the document are promulgated, compliance will be a prerequisite for placement of certain types of K046 waste in units designated as land disposal units according to 40 CFR Part 268. The effective date of these treatment standards would be June 9, 1990. In August 1988, EPA established two subcategories for K046 waste--reactive and nonreactive--and promulgated a treatment standard for nonwastewaters in the nonreactive subcategory (see 53 FR 31138, August 17, 1988). The development of that treatment standard was described in the BDAT background document for the K046 nonreactive subcategory (USEPA 1988a). The treatment standard, a concentration-based standard for lead, was based on performance data from stabilization of a nonreactive K046 waste.
