(A) Bonds may be secured by a trust indenture between the authority and a corporate trustee, which may be the State Treasurer or a bank having trust powers or a trust company designated by the State Treasurer. A trust indenture may contain provisions for protecting and enforcing the rights and remedies of the bondholders which are reasonable and proper, including covenants setting forth the duties of the authority in relation to the exercise of its powers and the custody, safekeeping, and application of its money. The authority may provide by the trust indenture for the payment of the proceeds of the bonds and all or any part of the revenues of the authority to the trustee under the trust indenture or to some other depository, and for the method of its disbursement with safeguards and restrictions prescribed by it.

(B) A bond resolution or trust indenture pursuant to which bonds are issued may contain provisions which are part of the contract with the holders of the bonds as to such matters relating to the terms of the bonds or the security or protection of the holders of the bonds which the authority considers appropriate.

(C) Bonds may be primarily secured by a pool of obligations issued by local governments when the proceeds of the local government obligations are applied to local environmental facility projects.
