(Hazardous waste removed from the tank system is subject to the requirements of this Title.)009.04 Comply with the following special requirements for ignitable or reactive waste: 009.04A Ignitable or reactive waste must not be placed in a tank, unless: 009.04A1 The waste is treated, rendered, or mixed before or immediately after placement in a tank so that the resulting waste, mixture, or dissolution of material no longer meets the definition of ignitable or reactive waste under Chapters 3, 007 and 009 and Chapter 16, 001. 02 is complied with; or009.04A2 The requirements in Chapter 16, 002. 02 are complied with.009.05 Comply with the special requirements for incompatible wastes in Chapter 16, 001.03 and 001. 04 .128 Neb.
