2. Any applicant that applies for a substantial modification of a wireless support structure within the jurisdiction of any authority, planning or otherwise, that has adopted planning and zoning regulations in accordance with sections 67.5090 to 67.5103 shall:

(1) Submit the necessary copies and attachments of the application to the appropriate authority. Each application shall include a copy of a lease, letter of authorization or other agreement from the property owner evidencing applicant's right to pursue the application; and

(2) Comply with applicable local ordinances concerning land use and the appropriate permitting processes.

3. Disclosure of records in the possession or custody of authority personnel, including but not limited to documents and electronic data, shall be subject to chapter 610 .

4. The authority, within one hundred twenty calendar days of receiving an application for a substantial modification of wireless support structures, shall:

(1) Review the application in light of its conformity with applicable local zoning regulations. An application is deemed to be complete unless the authority notifies the applicant in writing, within thirty calendar days of submission of the application, of the specific deficiencies in the application which, if cured, would make the application complete. Upon receipt of a timely written notice that an application is deficient, an applicant may take thirty calendar days from receiving such notice to cure the specific deficiencies. If the applicant cures the deficiencies within thirty calendar days, the application shall be reviewed and processed within one hundred twenty calendar days from the initial date the application was received. If the applicant requires a period of time beyond thirty calendar days to cure the specific deficiencies, the one hundred twenty calendar days' deadline for review shall be extended by the same period of time;

(2) Make its final decision to approve or disapprove the application; and

(3) Advise the applicant in writing of its final decision.

5. If the authority fails to act on an application for a substantial modification within the one hundred twenty calendar days' review period specified under subsection 4 of this section, or within such additional time as may be mutually agreed to by an applicant and an authority, the application for a substantial modification shall be deemed approved.

6. A party aggrieved by the final action of an authority, either by its affirmatively denying an application under the provisions of this section or by its inaction, may bring an action for review in any court of competent jurisdiction within this state.
