				plant disposal activities, the vehicle is not required to be flushed or
				cleaned.

				and equipment shall be stored in a manner which will not cause a
				nuisance.

				following cases, minimum allowable tank capacity is 1,000 gallons:

				restrooms.

				approval of any trailer-mounted servicing equipment shall be on an individual
				basis for specific uses only.

				Portable tanks or containers used for servicing, other than approved
				trailer-mounted servicing equipment, are prohibited. All approvable tanks or
				containers shall be attached to the vehicle by welding or bolts and cannot be
				used for containing liquids that are intended for direct contact with humans or
				animals. Alternative equipment proposed for use to service septage on islands
				shall be evaluated by the department on a case-by-case basis.
(g) Each tank shall be strong enough for all
				conditions of operation, leakproof, contain inertia baffles and be designed to
				be kept tightly closed to prevent spillage or escape of odors while in transit
				or storage. Tanks shall be constructed of suitable metal or materials approved
				by the department and mounted permanently on a truck chassis, except where
				trailer-mounted equipment is approved.

				spreading of septage shall have a splash plate or some other department
				approved method or device to facilitate uniform septage application.

				shall be stored so as to prevent leakage or dripping of septage in transit, or
				the ends of hoses and pipes shall be connected or sealed with tightly fitted
				caps or covers, or the hoses and pipes shall be cleaned with water between uses
				so as not to cause a nuisance by leakage or dripping of septage during transit.
				On vehicles used solely for servicing portable restrooms, suction hoses used
				for cleaning portable restrooms may alternatively be provided with two shutoff
				valves with one located at the tank and the other shutoff valve located on the
				wand end of the suction hose.

				exception of vehicles used by farmers, used in servicing shall meet all of the
				following identification requirements:
1. No
				person, unless exempt by statute or this chapter, may operate a vehicle used
				for servicing unless a valid business license sticker is prominently displayed
				on the rear of the vehicle servicing tank. If the servicing vehicle is used
				only for servicing and transporting portable restrooms and the placement of the
				sticker on the rear of the vehicle servicing tank prevents the sticker from
				being visible when transporting portable restrooms, the sticker may be applied
				to an alternative location on the vehicle approved by the department.
2. Each licensee shall display on at least
				one side of the vehicle the words "Wisconsin Sanitary Licensee" and immediately
				under these words "License No. " with the number of its license in the space
				provided with letters and numbers at least 2 inches high and all lettering and
				numbering shall be in distinct color contrast to its background.
2m. Each business that uses a vehicle that is
				used by more than one business, whether under a single owner or separate
				owners, shall register the vehicle under each business's license and each
				business license number shall be displayed on the vehicle.
3. Each licensee shall display on each
				vehicle the capacity of the tank in gallons, in lettering and numbers at least
				2 inches high in a color distinct from the background and readily visible on
				the rear of any vehicle used in servicing. This display requirement does not
				apply if the capacity of the vehicle tank is 1,000 gallons or less and the
				servicing vehicle is used only for servicing and transporting portable
				restrooms. If a vehicle carries clear water and septage, only the septage
				capacity shall be listed.
(n) Starting July 1, 1997, all servicing
				equipment used for surface spreading of septage, including equipment in service
				prior to January 1, 1997, shall have a vehicle cab controlled discharge valve.
				New servicing equipment put into operation after January 1, 1997 shall be in
				conformance with this paragraph prior to use.
