(a) The public entities that participate in a public utility agency may by concurrent ordinances:
(1) add a public entity to, or delete a public entity from, participation in the public utility agency; or
(2) dissolve the public utility agency and transfer all obligations, assets, permits, and licenses of the public utility agency to the remaining public entities.
(b) A public entity that is the only remaining participant in a public utility agency may by ordinance dissolve the public utility agency in accordance with Subsection (a)(2).
(b) A participating public entity may withdraw from a public utility agency by providing an ordinance or resolution of the governing body of the participating public entity to the agency not later than the 180th day before the proposed date of withdrawal. A participating public entity may not withdraw from a public utility agency under this subsection if bonds, notes, or other obligations of the agency are secured by the revenues of the participating public entity, unless the agency adopts a resolution approving the withdrawal. Upon withdrawal, a participating public entity assumes the outstanding debt attributable to that entity from the agency on a prorated basis equal to that entity's benefit and has, without compensation from the agency, no further rights, duties, or obligations relating to the agency or ability to receive service from the facilities of the agency.
