You may store your cart where you operate if you utilize a mobile support unit. In order to have a mobile support unit, you will be required to submit plans. The mobile support unit will be used to remove all food, utensils, water, waste water and other food contact surfaces and transport these items to an approved commissary for storage, cleaning or sanitation. Otherwise, the entire cart must be returned back to the commissary at the end of each operating day for storage, servicing and cleaning.
