40 CFR § 265.140 - Applicability.
(1) Disposal facilities;
(c) States and the Federal government are exempt from the requirements of this subpart.
(d) The Regional Administrator may replace all or part of the requirements of this subpart applying to a regulated unit with alternative requirements for financial assurance set out in the permit or in an enforceable document (as defined in 40 CFR 270.1(c)(7)), where the Regional Administrator:
(1) Prescribes alternative requirements for the regulated unit under § 265.90(f) and/or 265.110(d), and
(2) Determines that it is not necessary to apply the requirements of this subpart because the alternative financial assurance requirements will protect human health and the environment.
