Iowa Code § 479.26
Before any permit is granted under this chapter the applicant must satisfy the board that the applicant has property within this state other than pipelines, subject to execution of a value in excess of two hundred fifty thousand dollars, or the applicant must file and maintain with the board a surety bond in the penal sum of two hundred fifty thousand dollars with surety approved by the board, conditioned that the applicant will pay any and all damages legally recovered against it growing out of the construction or operation of its pipeline and gas storage facilities in the state of Iowa. When the pipeline company deposits with the board security satisfactory to the board as a guaranty for the payment of the damages, or furnishes to the board satisfactory proofs of its solvency and financial ability to pay the damages, the pipeline company is relieved of the provisions requiring bond.
