(a) Before we approve a residential lease, we must determine that the lease is in the best interest of the Indian landowners. In making that determination, we will:

(1) Review the lease and supporting documents;

(2) Ensure compliance with applicable laws and ordinances;

(3) If the lease is being approved under 25 U.S.C. 415,assure.S.C. 415(a); and

(4) Require any lease modifications or mitigation measures necessary to satisfy any requirements including any other Federal or tribal land use requirements.

(b) Upon receiving a residential lease package, we will promptly notify the parties whether the package is or is not complete. A complete package includes all the information and supporting documents required under this subpart, including but not limited to, NEPA review documentation and valuation documentation, where applicable.

(1) If the residential lease package is not complete, our letter will identify the missing information or documents required for a complete package. If we do not respond to the submission of a residential lease package, the parties may take action under § 162.363.

(2) If the residential lease package is complete, we will notify the parties of the date of receipt. Within 30 days of the receipt date, we will approve or disapprove the lease or return the package for revision.

(c) If we do not meet the deadlines in this section, then the parties may take action under § 162.363.

(d) We will provide any lease approval or disapproval and the basis for the determination, along with notification of any appeal rights under part 2 of this chapter, in writing to the parties to the lease.

(e) Any residential lease issued under the authority of the Native American Housing Assistance and Self-Determination Act, 25 U.S.C 4211(a), whether on tribal land or on individually owned Indian land, must be approved by us and by the affected tribe.

(f) We will provide approved residential leases on tribal land to the lessee and provide a copy to the tribe. We will provide approved residential leases on individually owned Indian land to the lessee, and make copies available to the Indian landowners upon written request.
