(a) Upon the hearing, if it appears that the United States Secretary of the Army, or such other federal agency as may have jurisdiction to consent to the construction of erections in navigable waterways, has approved or permissively authorized the proposed navigable water crossings, then the Arkansas Public Service Commission shall grant the prayer of the river crossing proprietor's petition unless the commission enters specific findings, based on a preponderance of the evidence, that:
(1) The proposed navigable water crossing, if constructed and operated as proposed, will jeopardize the public safety; or
(2) The construction of the proposed navigable water crossing at the point specified in the petition will result in an unlawful interference with some other paramount public or private use of the navigable waterway or its underlying bed at the point of the proposed crossing.
(b) In the event the commission finds that the proposed navigable water crossing would jeopardize the public safety if constructed and operated as proposed, it may grant the prayer of the river crossing proprietor's petition subject to such alteration of the proposed plans, specifications, and construction methods as may be in the interest of the public safety.
