(a) Within 30 days after receiving a letter of intent, or a documented petition if a letter of intent has not previously been received and noticed, the Assistant Secretary shall acknowledge such receipt in writing and shall have published within 60 days in the Federal Register a notice of such receipt. This notice must include the name, location, and mailing address of the petitioner and such other information as will identify the entity submitting the letter of intent or documented petition and the date it was received. This notice shall also serve to announce the opportunity for interested parties and informed parties to submit factual or legal arguments in support of or in opposition to the petitioner's request for acknowledgment and/or to request to be kept informed of all general actions affecting the petition. The notice shall also indicate where a copy of the letter of intent and the documented petition may be examined.
(b) The Assistant Secretary shall notify, in writing, the governor and attorney general of the state in which a petitioner is located. The Assistant Secretary shall also notify any recognized tribe and any other petitioner which appears to have a historical or present relationship with the petitioner or which may otherwise be considered to have a potential interest in the acknowledgment determination.
