Notwithstanding any provision to the contrary in sections 403.21 to 403.40, the Statewide Radio Board has the final authority over technical and operational standards necessary to provide for the development and implementation of the ARMER system that maximizes the integration of the public safety radio communication system throughout the state, including the backbone previously established by the Metropolitan Radio Board. Technical and operational standards that do not interfere with the integration of the system may be established locally or regionally.
