| Customers of a local exchange carrier who receive local, flat- |
rate, basic service within a single exchange area may petition |
the commission to expand their basic service calling area.__Upon |
written petition by 5 or more customers of a local exchange |
carrier, the commission shall open a proceeding to expand the |
basic service calling area.__The commission shall hold at least |
one public hearing.__The commission, within 4 months of the |
filing of the written petition, shall issue an order establishing |
an expanded basic service calling area for the area served by the |
petitioning customers.__The commission's order must direct the |
carrier to file within one year a financial report on the costs |
of expanding the basic service calling area.__Upon receipt of the |
carrier's filing, the commission shall conduct an investigation |
to determine the costs, if any, attributable to the expansion.__ |
The commission may only allow recovery of these costs if the |
carrier demonstrates that nonrecovery of the costs will result in |
the carrier earning less than a reasonable rate of return. |
