Such petition shall specify the plan or program of the district and the uses to which it is proposed to put the proceeds of such issue and such other matters as are necessary fully to advise said department of the nature of the corporate purpose, in furtherance of which such issue is proposed, and said petition shall include such other information as may be required by the rules of the Department of Finance. The Department of Finance shall grant such consent only after it finds that such issue or sale serves some public need and is in the public interest. It shall be unlawful for the district to use the proceeds of any such issue or sale contrary to the plan and purposes presented to the Department of Finance in obtaining its consent thereto. The district applying for such consent is authorized to pay such fees as shall be lawfully assessed against it by the Department of Finance.
