Period within which certain claims must be filed

Notwithstanding any other provision of this chapter (but subject to subsection (b)), any claim by a State for payment with respect to an expenditure made during any calendar quarter by the State— The Secretary shall waive the requirement imposed under subsection (a) with respect to the filing of any claim if he determines (in accordance with regulations) that there was good cause for the failure by the State to file such claim within the period prescribed under subsection (a). Any such waiver shall be only for such additional period of time as may be necessary to provide the State with a reasonable opportunity to file such claim. A failure to file a claim within such time period which is attributable to neglect or administrative inadequacies shall be deemed not to be for good cause.
