flammable and combustible liquids shall be periodically inspected for wear and
stress. Hose or fittings that are suspect or have the appearance of wear shall
be immediately replaced.
(f)
Emergency shutoff valve.
1. All new or replacement dispensing devices
for Class I liquids shall be provided with a double-poppet, heat-actuated
emergency shutoff valve that will stop the flow of fuel if the dispenser is
displaced from its base, or if the fusible link is activated.
2. Anytime an emergency shutoff valve is
replaced, the valve shall comply with subd. 1.
(fm)
Testing. Emergency
electrical disconnect shall be tested at least annually. Tests conducted on
underground storage tank dispensing systems shall be documented on
functionality verification form, TR-WM-139.
(g)
Water level in tanks.
1. Water may not exceed the following depths,
as measured with water-indicating paste, in any tank utilized in storing the
following fuels, except as otherwise approved by the department:
a. Gasoline-alcohol blends, biodiesel,
biodiesel blends, and E85 fuel ethanol- 1/4 inch.
b. Aviation gasoline and aviation turbine
fuel-one inch.
c. Gasoline, diesel,
gasoline-ether, kerosene, and other fuels -2 inches.
2. Tanks used to store motor fuels or
kerosene shall have the water level checked and recorded at least once per
month.
3. Anytime the water level
exceeds the levels in this paragraph, sale of the fuel shall be stopped. The
cause of the water ingress shall be determined and corrected and excess water
removed from the tank within 5 days.
4. Water levels in tanks at retail facilities
subject to the requirements of ch. ATCP 94 shall be maintained in accordance
with that chapter.
(2) PORTABLE CONTAINERS.
(a) Portable containers for the sale or
purchase of a flammable or combustible liquid shall be clearly marked with the
name of the product.
(b) Liquids
having a flash point of less than 100°F may not be dispensed into a
portable container or portable tank unless all of the following conditions are
met:
1. The container or tank is
substantially bright red in color.
2. The container or tank has a listing mark
from an independent testing agency.
(c) No kerosene, fuel oil, or similar liquids
having a flash point of 100°F or more may be filled into any portable
container or portable tank that is colored red.
(3) DISPENSING OPERATIONS.
(a) All dispensing areas shall be provided
with lighting where fueling operations are performed during hours of
darkness.
(b) Dispenser displays
shall be located to be fully visible to the person fueling the
vehicle.
(c) All surface area
within a 30 foot radius of the dispenser shall be maintained free of high
grass, weeds, and debris.
(cm) No

3 feet horizontally of the dispenser cabinet or tank.
(d) Fuel may not be dispensed using tank
pressurization.
(4)
DISPENSER LABELING. Dispensers at facilities subject to the requirements of ch.
ATCP 94 shall be labeled in accordance with the requirements of that
chapter.
(5) ATTENDED AND
UNATTENDED FUELING.
(a) To be considered as
being an attended fueling facility, there shall be at least one attendant
regularly on duty on a daily basis, but not necessarily during all hours of
operation, to supervise, observe, and control the actual dispensing of
fuel.
(b) All point-of-sale
dispensing systems, whether attended or not, shall meet the requirements in
NFPA 30A section 9.5 for unattended self-service motor fuel dispensing
facilities except a telephone or other means for contacting emergency services
available to the public is not required.
(c)
1. All
new fueling facilities that are not attended as specified in par. (a) shall
have pipeline catastrophic leak detection, and sump monitors if so equipped,
that will automatically shut down either the submersible pump or the dispenser
operation upon detection of a system leak.
2. All existing fueling facilities that are
not attended as specified in par. (a) shall have pipeline catastrophic leak
detection, and sump monitors if so equipped, that will do either of the
following upon detection of a system leak:
a.
Automatically shut down either the submersible pump or the dispenser
operation.
b. Send an alarm to a
facility that is staffed 24 hours a day, 7 days a week.
Note: As an example, par. (c) would not apply
to a convenience store and retail station that closes each day at 10:00 p.m.
and then continues to operate its point-of-sale, card-reader dispensers until
the store and station reopen the next day.
(6) OVERFILL PROTECTION.
Before delivery of product into a storage tank, the driver, operator or
attendant of the tank vehicle shall measure the available capacity of the tank.
The available capacity shall be more than the volume of the product to be
delivered.
(7) PRODUCT TRANSFERS.
Fuel from public access fueling dispensers may only be transferred into
integral vehicle and equipment fuel supply tanks, contractor pickup mounted
cross-over tanks, and approved portable containers that have a capacity of 10
gallons or less.
(8) SEPARATION
FROM GASEOUS FUELS. A motor fuel dispenser shall be separated from storage
vessels and dispensers for liquefied petroleum gas, liquefied natural gas,
compressed natural gas, gaseous hydrogen, and liquefied hydrogen that are
regulated by ch. SPS 340. Separation distances shall be the distances that are
required by NFPA 30A chapter 12.
Based on definitions of "dispenser," "dispensing area,"
and "dispensing system" in s.
ATCP 93.050(38), (40), and
(41), respectively, the distances under this
subsection are measured to the body of the device that measures and dispenses
the liquid product, rather than to the distal end of the hose and nozzle which
can be extended away from that device.
