(2) The commission may, upon application of the telecommunications utility, after opportunity for hearing and for good cause shown, make such supplemental orders in the premises as the commission finds necessary or appropriate, and may by any such supplemental order modify the provisions of any previous order as to the particular purposes, uses, extent to which, or the condition under which, any security theretofore authorized or its proceeds may be applied. Such supplemental orders are subject to the requirements of ORS 759.315. The period of time permitted under subsection (1) of this section for disposing of applications shall not apply to supplemental orders.

(3) If a commission or other agency is empowered by another state to regulate and control the amount and character of securities to be issued by any telecommunications utility within such other state, the commission of Oregon has power to agree with such commission or agency of such other state on the issue of stocks, bonds, notes, other evidences of indebtedness or securities by a telecommunications utility owning or operating a telecommunications utility both in such state and in this state, and has power to approve such issue jointly with such commission or agency and to issue a joint certificate of such approval. However, no such joint approval is required in order to express the consent to and approval of such issue by the State of Oregon if the issue is separately approved by the Oregon commission.
