In order to insure that proper preparation and implementation of such systems can be accomplished as provided in Section 2803 of this title, the Oklahoma 9-1-1 Management Authority may develop an overall plan prior to development of any system and shall coordinate the implementation of systems to be established pursuant to the provisions of Section 2803 of this title. Any such plan shall contain an estimate of the costs of installing alternate 911 systems and an estimate of the first year's additional operating expenses, if any. The Authority may formulate a plan by which it and the public agencies and public safety agencies involved may share proportionately the costs of any system and method from their current funds. The Authority may aid such agencies in the formulation of concepts, methods and procedures which will improve the operation of systems and which will increase cooperation between public safety agencies. The Authority may consult at regular intervals with the State Fire Marshal, the Oklahoma State Bureau of Investigation, the State Department of Health, the Department of Emergency Management and the public utilities in this state providing telephone service.
