(1) No charge shall be imposed for a customer's initial selection of a primary intraLATA carrier. Each local exchange carrier shall allow customers to change their selection of a primary intraLATA carrier one time only at no charge within 90 days following implementation of intraLATA dialing parity in an exchange. Any charges for subsequent changes shall be the same as those imposed for changing interLATA carriers.

(2) In cases in which customers change both their intraLATA PIC and their interLATA PIC at the same time to either the same carrier or to separate carriers, only one of the following PIC change charges shall apply:

(a) the associated intraLATA PIC change charge;

(b) the associated interLATA PIC change charge; or

(c) the total of one-half of the associated intraLATA PIC change charge plus one-half of the associated interLATA PIC change charge.

(i) Each one-half charge may be shown separately on the customer bill.

(3) No PIC change order shall be submitted to a local exchange carrier unless and until the order has been confirmed in accordance with 69-3-1303 , MCA and the rules adopted by the commission in ARM 38.5.3801 through 38.5.3810.
