charges and other revenues, or any part thereof, (whether derived
from the auxiliary facility in connection with which the bonds of
any issue shall have been issued or from other auxiliary facilities)
designated as security for such bonds by the resolution authorizing
the issuance of such bonds or in the trust agreement securing the

needed to provide for the payment of such items (1), (2), (3) and
(4) may be used for any other lawful purpose to the extent provided
