The Department may, in its discretion, prescribe methods and forms for keeping accounts, records and books to be used by an Authority, and prescribe accounts to which particular outlays and receipts shall be entered, charged, or credited. The Department may require an Authority to file periodical reports, but not more frequently than quarterly, covering its operations and activities in a form prescribed by the Department. The Department may also, from time to time, require an Authority to provide specific answers to questions on subjects when the Department desires information on those subjects.
The Department may investigate the conditions and affairs of an Authority, its dealings, transactions or relationships and the manner in which projects are managed, and may through its members or employees enter upon and inspect the property, equipment, buildings, plants and offices of an Authority and examine its books, contracts, records, documents and papers.
