(a) Notwithstanding any other provision of this title, if a telecommunications utility installs facilities to serve customers located in a defined geographic area to provide telecommunications services, including basic local telecommunications service, before the holder of the certificate of convenience and necessity installs facilities to serve customers located in that defined geographic area, the holder of the certificate of convenience and necessity may petition the commission for an order relieving the utility of the utility’s designation as the provider of last resort in that defined geographic area.
(b) The commission shall relieve the holder of the certificate of convenience and necessity of the obligations of service as the provider of last resort for the defined geographic area, and the commission shall designate the facilities-based telecommunications utility as the provider of last resort if the commission determines that:
(1) the holder of the certificate of convenience and necessity does not have facilities in place to provide basic local telecommunications service to all customers within that defined geographic area;
(2) another certificated telecommunications utility has installed facilities adequate to provide that service throughout that area; and
(3) the public interest would be served by transferring the provider of last resort obligations for that area.

(c) The commission shall complete proceedings necessary to make the determinations prescribed by this section not later than the 91st day after the date the petition is filed under Subsection (a).
