Any resolution or trust indenture authorizing the issuance of securities or any other instrument appertaining thereto may contain covenants and other provisions, notwithstanding such covenants and provisions may limit the exercise of powers conferred by the Solid Waste Authority Act, in order to secure the payment of such securities in agreement with the holders and owners of such securities, as the board may determine, including without limiting the generality of the foregoing, all such acts and things as may be necessary or convenient or desirable in order to secure the authority’s securities, or in the discretion of the board tend to make the securities more marketable, notwithstanding that such covenant, act or thing may not be enumerated in that act, it being the intention of that act to give the authority power to do all things in the issuance of securities and for their security except as specifically limited in that act.
