(a) This Code section shall apply in counties where the governing authorities of more than one local government have adopted a resolution to impose a wireless enhanced "911" charge in accordance with the provisions of subsection (a) of Code Section 46-5-133 and notwithstanding any contrary provision of Code Section 46-5-133 or 46-5-134.

(b) A wireless service supplier may certify to any of the governing authorities described in subsection (a) of this Code section that the wireless service supplier is unable to determine whether the billing addresses of its subscribers are within the geographic area that is served by such local government. Upon such certification, the wireless service supplier shall be authorized to collect the wireless enhanced "911" charge from any of its subscribers whose billing address is within the county and is within an area that is as close as reasonably possible to the geographic area that is served by such local government. The wireless service supplier shall notify such subscribers that if such subscriber's billing address is not within the geographic area served by such local government, such subscriber is not obligated to pay the wireless enhanced "911" charge.

(c) Unless otherwise provided in an agreement among the governing authorities described in subsection (a) of this Code section, the charges collected by a wireless service supplier pursuant to this Code section shall be remitted to such governing authorities based upon the number of calls from wireless telecommunications connections that each such individual local government receives and counts relative to the total number of calls from wireless telecommunications connections that are received and counted by all of such local governments.

(d) The authority granted to a wireless service supplier pursuant to this Code section shall terminate (1) on the date that the wireless service supplier certifies to a governing authority described in subsection (a) of this Code section that the wireless service supplier is able to determine whether the billing addresses of its subscribers are within the geographic area that is served by such governing authority or (2) on the date which is 180 days from the date that any of its subscribers were first billed under this Code section, whichever is earlier. Upon termination of such authority, the wireless service supplier shall collect the wireless enhanced "911" charge as provided in Code Section 46-5-134.
