RULE 424. GASOLINE DISPENSING FACILITIES

(Adopted 2/23/88; Revised 1/10/89;7/18/89)

A. Definitions. For the purposes of this Rule, the following definitions shall apply:

1. "ARB-certified vapor recovery system" means a vapor recovery system which has been certified by the State Air Resources Board pursuant to Section 41954 of the Health and Safety Code.

2. "Excavation" means exposure to view by digging.

3. "Existing gasoline dispensing facility" means any gasoline dispensing facility operating, constructed, or under construction as of January 10, 1989.

4. "Gasoline" means any organic liquid (including petroleum distillates and methanol) having a Reid vapor pressure of four (4) pounds or greater and used as a motor vehicle fuel or any fuel which is commonly or commercially known or sold as gasoline.

5. "Gasoline Dispensing Facility" means any stationary facility which dispenses gasoline directly into the fuel tanks of motor vehicles. This facility shall be treated as a single source which includes all necessary equipment for the exclusive use of the facility, such as nozzles, dispensers, pumps, vapor return lines, plumbing, and storage tanks.

6. "Hold-Open Latch" means the integral component of a gasoline dispensing nozzle which permits the nozzle to remain open without a sustained effort on the part of the refueler.

7. "Leak":

a. The dripping at a rate of more than three (3) drops per minute of liquid containing reactive organic compounds; or

b. An emission of gaseous reactive organic compound which causes an appropriate analyzer sampling one (1) centimeter from a source to register at least 10,000 ppm, as methane, as determined by EPA Reference Method 21; or

c. An emission of gaseous reactive organic compounds which causes a soap bubble score of 3 or greater using the alternative screening procedure in EPA Reference Method 21.

d. The following are exceptions to the above definition and are not considered by this rule to be leaks:

1) Liquid leaks from a well maintained disconnecting transfer fitting of not more than 10 milliliters per disconnect, averaged over three disconnects.

2) Gaseous emissions from pressure relief devices on tanks when the process pressure exceeds the limit setting specified for the device.

8. "Motor vehicle" has the same meaning as defined in Section 415 of the Vehicle Code.

9. "New gasoline dispensing facility" means any gasoline dispensing facility which is not constructed or under construction as of January 10, 1989.

10. "Owner or operator" means the owner or operator of a facility which dispenses gasoline.

11. "Phase I vapor recovery system" means a gasoline vapor recovery system which recovers vapors during the transfer of gasoline from delivery tanks into stationary storage tanks.

12. "Phase II vapor recovery plumbing" means all portions of an ARB-certified Phase II vapor recovery system excluding those components installed above ground.

13. "Phase II vapor recovery system" means a gasoline vapor recovery system which recovers vapors during the fueling of motor vehicles from stationary storage tanks.

14. "Soap Bubble Score" means the magnitude of a leak as indicated by the size of bubble formation resulting from spraying the suspected area with a standard solution. The solution shall consist of 100 ml of rug shampoo in 1 gallon of distilled water or 100 ml of rug shampoo in 1 gallon of a 50/50 mixture of glycol and distilled water. Soap scores are assigned following six seconds of observation as follows:

Score Estimated Bubble Volume (cubic centimeters in 6 seconds)

0 No detectable bubble

1 Up to 1 cc in 6 seconds

2 Greater than 1 cc but less than 10 cc in 6 seconds

3 Greater than 10 cc but less than 100 cc in 6 seconds

4 Greater than 100 cc in 6 seconds

15. "Tank replacement" means replacement of one or more stationary gasoline storage tanks at an existing gasoline dispensing facility or excavation of 50 percent or more of an existing gasoline dispensing facility's total underground liquid gasoline piping from the stationary storage tanks to the gasoline dispensers.

16. "Throughput" means the volume of gasoline dispensed at a gasoline dispensing facility.

B. Phase I Vapor Recovery System Requirements

1. No owner or operator shall transfer, or permit the transfer, or provide equipment for the transfer of gasoline, and no other person shall transfer gasoline from a gasoline delivery vehicle into a stationary storage tank at a gasoline dispensing facility unless an ARB-certified Phase I vapor recovery system is installed on the stationary storage tank and used during transfer.

2. The installation provisions of Subsection B.1 shall not apply to:

a. Storage tanks with a capacity of less than 1,500 gallons.

b. Storage tanks used the majority of the time for the fueling of implements of husbandry as defined in Division 16, Chapter 1, of the Vehicle Code.

c. Storage tanks used exclusively to fuel motor vehicles with a fuel capacity of five gallons or less.

d. Storage tanks at an existing gasoline dispensing facility which receives gasoline exclusively from delivery tanks that are not required to be equipped with vapor recovery systems as described in Rule 407.B.3.

e. The temporary storage of gasoline in flexible containers to support equipment responding to an emergency or for the purposes of training to support such equipment.

3. The usage provisions of Subsection B.1 shall not apply to:

a. Storage tanks at an existing gasoline dispensing facility while receiving gasoline from delivery tanks that are not required to be equipped with vapor recovery systems as described in Rule 407.B.3.

b. Deliveries made and equipment used to completely fill stationary tanks for the purpose of leak testing, provided that such deliveries do not exceed 1,000 gallons at each tank.

4. Any Phase I vapor recovery system, installed pursuant to the provisions of this Rule, shall be maintained and operated in accordance with the procedures used when that system type was certified by the California Air Resources Board. All vapor recovery equipment shall be maintained in good working order and shall not leak.

5. Any person storing or transferring gasoline shall follow good operating practices including, but not limited to: preventing spills, storing gasoline in closed containers, and disposing of gasoline in compliance with all state and local regulations. C. Phase II Vapor Recovery System Requirements

1. No owner or operator shall transfer, permit the transfer or provide equipment for the transfer of gasoline from a stationary storage tank at a gasoline dispensing facility into a motor vehicle fuel tank unless an ARB-certified Phase II vapor recovery system is installed and used during the transfer.
