Insufficient appropriations

If, for any fiscal year, the funds appropriated for payments under this subpart are insufficient to satisfy fully all entitlements, as calculated under subsections (b) and (c) (but at the maximum grant level specified in such appropriation), the Secretary shall promptly transmit a notice of such insufficiency to each House of the Congress, and identify in such notice the additional amount that would be required to be appropriated to satisfy fully all entitlements (as so calculated at such maximum grant level).
