History: CR 17-092: cr. Register October 2019 No. 766, eff. 11-1-19.

ATCP 93.605 General fuel dispensing requirements.

(1) Standards and inspections.

(a) General. Periodic and annual inspections and maintenance shall be conducted in accordance with PEI RP500 and RP900, except that PEI RP 900, Section 6, Daily UST Inspection Checklist items may be performed at least monthly rather than daily.

Note: In addition to the PEI RP500 and RP900 maintenance requirements, further criteria on maintaining USTs is available in standard STI R-111, Storage Tank Maintenance, from the Steel Tank Institute, at www.steeltank.com. This standard is applied to USTs under ss.

(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.

(cm) No combustible materials, including pallets and packaging material, may be within 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.

Note: 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.
