(i) The requirements of 40 CFR 264, Subpart CC do not apply to a waste management unit that is used solely for on-site treatment or storage of hazardous waste that is placed in the unit as the result of implementing remedial activities required under the corrective action authorities of RCRA §§3004(u), 3004(v), or 3008(h), CERCLA authorities, similar federal authorities, or these rules.

(ii) For the owner and operator of a facility subject to Subpart CC who received a final permit under RCRA §3005 or these rules prior to December 6, 1996, the requirements of this subpart shall be incorporated into the permit when the permit is reissued in accordance with the requirements of 40 CFR 124.15 or reviewed in accordance with the requirements of 40 CFR 270.50(d).
