Hazardous wastes from non-specific sources

Hazardous wastes from non-specific sources. (1) Listed hazardous waste from non-specific sources. The following solid wastes are listed hazardous wastes from non-specific sources unless they are excluded under ss. NR 660.20 and 660.22 and listed in 40 CFR part 261 , Appendix IX: (2) Listing specific definitions. (a) For the purposes of the F037 and F038 listings, oil or water or solids is defined as any combination of oil, water, or solids. (b) 1. For the purposes of the F037 and F038 listings, aggressive biological treatment units are defined as units which employ one of the following 4 treatment methods: activated sludge; trickling filter; rotating biological contactor for the continuous accelerated biological oxidation of wastewaters; or high-rate aeration. High-rate aeration is a system of surface impoundments or tanks, in which intense mechanical aeration is used to completely mix the wastes, enhance biological activity, and the units employ a minimum of 6 hp per million gallons of treatment volume; and either the hydraulic retention time of the unit is no longer than 5 days; or the hydraulic retention time is no longer than 30 days and the unit does not generate a sludge that is a hazardous waste by the Toxicity Characteristic. 2. Generators and treatment, storage and disposal facilities have the burden of proving that their sludges are exempt from listing as F037 and F038 wastes under subd. 1. Generators and treatment, storage and disposal facilities shall maintain, in their operating or other on-site records, documents and data sufficient to prove that the unit is an aggressive biological treatment unit as defined in this subsection; and the sludges sought to be exempted from the definitions of F037 or F038 were generated in the aggressive biological treatment unit. (c) 1. For the purposes of the F037 listing, sludges are considered to be generated at the moment of deposition in the unit, where deposition is defined as at least a temporary cessation of lateral particle movement. 2. For the purposes of the F038 listing, sludges are considered to be generated at the moment of deposition in the unit, where deposition is defined as at least a temporary cessation of lateral particle movement and floats are considered to be generated at the moment they are formed in the top of the unit. (d) For the purposes of the F019 listing, the following apply to wastewater treatment sludges from the manufacturing of motor vehicles using a zinc phosphating process: 1. Motor vehicle manufacturing is defined to include the manufacture of automobiles and light trucks or utility vehicles, including light duty vans, pick-up trucks, minivans, and sport utility vehicles. Facilities shall be engaged in manufacturing complete vehicles, body and chassis or unibody, or chassis only. 2. A generator shall maintain in its on-site records documentation and information sufficient to prove that the wastewater treatment sludges to be exempted from the F019 listing meet the conditions of the listing. These records include all of the following: the volume of waste generated and disposed of off-site; documentation showing when the waste volumes were generated and sent off site; the name and address of the receiving facility; and documentation confirming receipt of the waste by the receiving facility. A generator shall maintain these documents on site for no less than 3 years. The retention period for the documentation is automatically extended during the course of any enforcement action or as requested by the department.
