# 264.256 Special requirements for ignitable or reactive waste.
Ignitable or reactive waste must not be placed in a waste pile unless the waste and waste pile satisfy all applicable requirements of 40 CFR part 268, and:
(a) The waste is treated, rendered, or mixed before or immediately after placement in the pile so that:
(1) The resulting waste, mixture, or dissolution of material no longer meets the definition of ignitable or reactive waste under § 261.21 or § 261.23 of this chapter; and
(2) Section 264.17(b) is complied with; or
(b) The waste is managed in such a way that it is protected from any material or conditions which may cause it to ignite or react.
