Depositing substance that will form obstruction to navigation.

Any person who shall deposit or cause to be deposited, in the waters of the Harbor of Mobile, any substance that will sink and form an obstruction to navigation, without first obtaining permission in writing, of the Alabama State Port Authority, which permission shall describe with an ordinary degree of certainty the place where such deposit shall be made, and which shall be recorded by the secretary-treasurer of the port authority, shall be guilty of a misdemeanor, and, upon conviction thereof, before a court of competent jurisdiction, shall be fined not less than $100.00 nor more than $500.00, or imprisoned for not less than 30 and not more than 90 days; but nothing herein shall be construed to prevent or interfere with the construction of work authorized by law to be done at any time in connection with the Mobile Harbor.
