Utah Code § 73-18a-8

The owner or whoever is lawfully vested with the possession, management, or control of a public marina or other public waterside facility used by a vessel for launching, docking, mooring, and related purposes shall be required to have, and properly maintain, waste receptacles or similar devices of proper design for the depositing of waste, litter, and human body waste, as required at locations where they can be conveniently used by a vessel's occupants. Waterside toilet facilities may be required if their absence contributes to or creates unsightliness or a hazard to the public health and welfare.
