Rules and regulations adopted under and in pursuance of the powers granted by Sections 8.10, 8.11 and 8.12 must be contained in an ordinance which shall be placed on file in the office of the Authority in typewritten or printed form for public inspection not less than 15 days before adoption. Such ordinance may prescribe such fines as the Board of Commissioners deems appropriate of not less than $1 nor more than $1,000 upon conviction for each offense, and may provide that, in case of continuing violation of any such rule or regulation, each calendar day that such violation continues constitutes a separate offense.
Notice of the filing of and public hearing upon any ordinance prescribing fines or penalties and of the date and time for its being publicly heard shall be published one time in a newspaper generally circulated within the Authority not more than 30 nor less than 15 days prior to the date of such hearing. Such ordinance may be amended at the public hearing and may be later amended where no new rule or regulation is adopted or existing fine or penalty modified, without pre-filing or publication of notice prior to the adoption of the amendatory ordinance. After adoption, typewritten or printed copies of each ordinance of an authority which prescribes fines or penalties shall be made available at the office of the authority for distribution upon request.
All fines, when collected, for violations of any such ordinance of an authority shall be paid into its treasury.
