The Board may investigate conditions in which it has an interest
within the area of the District, the enforcement of its ordinances, rules and
regulations, and the action, conduct and efficiency of all officers, agents
and employees of the District. In the conduct of such investigations the
Board may hold public hearings on its own motion, and shall hold public
hearings on complaint of any municipality within the District.
Each member of the Board shall have power to administer oaths, and the
secretary, by order of the Board, shall issue subpoenas to secure the

papers relevant to such investigations and to any hearing before the Board
or any member thereof.
Any circuit court of this State, upon application
of the Board or any member thereof, may compel the attendance of witnesses,
the production of books and papers, and giving of testimony before the
Board or before any member thereof or any officer's committee appointed by
the Board, by attachment for contempt or otherwise in the same manner as
the production of evidence may be compelled before the court.
