The principal of, and interest and premiums, if any, on any bonds issued by the State authority shall be secured by a pledge of the revenues and receipts out of which the same shall be made payable and may also be payable out of proceeds from the sale of the environmental facility acquired with proceeds of such bonds. The resolution under which the bonds are authorized to be issued, and any indenture executed as security for the bonds, may contain any agreements and provisions respecting the maintenance of the properties covered thereby, the fixing and collection of rents for any portions thereof leased by the State authority to others, the creation and maintenance of special funds from such revenues and the rights and remedies available in the event of default, including the designation of a trustee, all as the directing body shall deem advisable and not in conflict with the provisions hereof. Each pledge and agreement made for the benefit or security of any of the bonds of the authority shall continue effective until the principal of, and interest and premiums, if any, on the bonds for the benefit of which the same were made shall have been fully paid or provision for such payment duly made. In the event of default in such payment or in any agreements of the authority made as a part of the contract under which the bonds were issued, whether contained in the proceedings authorizing the bonds or in any indenture executed as security therefor, the payment or agreement may be enforced by mandamus, injunction, civil action or proceeding or the appointment of a receiver or any one or more of these remedies.
