479.12  Final order — condition.
  The board may grant a permit in whole or in part upon terms, conditions, and restrictions as to safety requirements and as to location and route as determined by it to be just and proper. Before a permit is granted to a pipeline company, the board, after a public hearing as provided in this chapter, shall determine whether the services proposed to be rendered will promote the public convenience and necessity, and an affirmative finding to that effect is a condition precedent to the granting of a permit.
