(a) When we receive a sublease that meets the requirements of this subpart, we will notify the parties of the date we receive it. If our approval is required, we have 30 days from receipt of the executed sublease, proof of required consents, and required documentation to approve or disapprove the sublease.

(b) If we do not send a determination within 30 days from receipt of required documents, the sublease is deemed approved to the extent consistent with Federal law. Unless the lease provides otherwise, provisions of the sublease that are inconsistent with Federal law will be severed and unenforceable; all other provisions of the sublease will remain in force.
