(a) A petition for designation of a service provider must:

(1) state with reasonable particularity the locations of the permanent residential or business premises for which the petitioners are requesting service;

(2) establish that those locations are within reasonable proximity to one another so that the petitioners possess a sufficient community of interest to warrant the designation of a provider and the expenditure of universal service funds necessary to establish service;

(3) except as provided by Subsection (b), be signed by at least five persons who:

(A) are not members of the same household;

(4) nominate as potential providers of service not more than five telecommunications providers serving territory that is contiguous to the location of the permanent residential or business premises using wireless or wireline facilities, resale, or unbundled network elements; and

(5) include as an attachment or an appendix documentation indicating the required residence or ownership, including a state-issued license or identification, tax records, deeds, or voter registration materials.

(b) The commission may accept a petition that is signed by fewer than five persons if a petitioner provides an affidavit stating that the petitioners have taken all reasonable steps to secure the signatures of the residents of permanent residential premises or the owners of permanent residential or business premises within reasonably close proximity to the petitioning premises who are not receiving telephone service when the petition is filed and who want telephone service initiated.
