   (6) Subject to any general or special directions given or conditions
 imposed by the Authority, any employee of the Authority to whom any
 functions or powers are delegated under this section may perform those

 the Authority for the actions of any employee of the Authority acting
 under the delegation.

   (10) Every delegation under this section shall, until it is revoked,
 continue in force according to its tenor, notwithstanding the fact that
 the employee of the Authority by whom it was made may cease to hold
 office, and shall continue to have effect as if made by the employee for
 the time being holding that office.

   (11) Every employee of the Authority purporting to act under any
 delegation under this section shall, when reasonably requested to do so,
 produce evidence of his or her authority to so act.
