RULE 461 - GASOLINE TRANSFER AND DISPENSING 

(a) Applicability 

This rule applies to the transfer of gasoline from any tank truck, trailer, or railroad 

tank car into any stationary storage tank or mobile fueler, and from any stationary 

storage tank or mobile fueler into any mobile fueler or motor vehicle fuel tank. 

(b) Definitions 

For the purpose of this rule, the following definitions shall apply: 

(1) ALTERED GASOLINE TRANSFER AND DISPENSING FACILITY is 

a Gasoline Transfer and Dispensing Facility with any of the following: 

(A) The removal or addition of storage tank(s), or changes in the 

number of fueling positions. 

(B) The replacement of storage tank(s), dispensing nozzle(s) or other 

equipment with different characteristics or descriptions from those 

specified on the existing permit. 

(2) BACKFILLING is the covering of the underground storage tank, piping or 

any associated components with soil, aggregate or other materials prior to 

laying the finished surface. 

(3) BELLOWS-LESS NOZZLE is any nozzle that incorporates an aspirator or 

vacuum assist system and a gasoline vapor capture mechanism at the 

motor vehicle filler neck, such that vapors are collected at the vehicle filler 

neck without the need for an interfacing flexible bellows. 

(4) BREAKAWAY COUPLING is a component attached to the coaxial hose, 

which allows the safe separation of the hose from the dispenser or the hose 

from the nozzle in the event of a forced removal such as in the case of a 

“drive-off.” 

(5) CARB CERTIFIED or certified by CARB means a Phase I or Phase II 

vapor recovery system, equipment, or any component thereof, for which 
Rule 461 (Cont.) (Amended April 6, 2012)

the California Air Resources Board (CARB) has evaluated its performance 

and issued a valid Executive Order pursuant to Health and Safety Code 

Section 41954. Each component of a system is a separate CARB certified 

item and cannot be replaced with a non-certified item or other items that 

are not certified for use with the particular system. Except for qualified 

repairs, a CARB certified component shall be as supplied by the qualified

component, as listed in California Code of Regulations, Title 17, Part III, 

Chapter 1, Subchapter 8, Section 94006. 

(22) MINOR DEFECT is a defect in any gasoline transfer and dispensing 

equipment, which renders the equipment out of good working order but 

which does not constitute a major defect.

would restore the function or performance of such equipment/component 

following the qualified manufacturer's instructions and using only the 

applicable CARB certified parts supplied by the qualified manufacturer. 

Unless otherwise authorized by CARB, a repair or maintenance shall not 

be considered a qualified repair if the action changes the size, shape or 

materials of construction of any gasoline vapor passage, or if it may 

otherwise obstruct, hinder, or reduce the recovery of gasoline vapors 

during operation. 

(30) REBUILD is an action that repairs, replaces, or reconstructs any part of a 

component of a vapor recovery system that forms the gasoline vapor 

passage of the component, or that comes in contact with the recovered 

gasoline vapors in the component. Rebuild does not include the 

replacement of a complete component with another CARB certified 

complete component; nor does it include the replacement of a spout,

notified at least 24 hours prior to the originally scheduled time. 

All notification under this subparagraph shall be provided by 

electronic mail or other District approved methods. 

Notwithstanding, the three-day notice may not be required for 

reverification tests conducted after a drive-off pursuant to clause 

(c)(2)(G)(i), provided that the person conducting the tests complies 

with all other applicable provisions of the rule.

weekend day provided that the retest meets the following 

conditions: 
Rule 461 (Cont.) (Amended April 6, 2012) 

461 - 19 

(I) The retest on a weekend day is necessary as the

repairs and retest following a failed reverification 

test cannot be completed by Friday. 

(II) The person conducting the test has notified the 

District pursuant to subparagraph (e)(4)(A) or left a 

phone notification before midnight of the day 

before the retest. 

(III) Tests shall be conducted from 7:00 a.m. through 

5:30 p.m. 

(IV) Upon request by the Executive Officer, the person 

who conducted the test on a weekend day for which

reverification testing at a mutually acceptable date 

but no later than 10 calendar days from the day the

test was conducted. The GDF shall pay the cost of 

the repeat reverification testing.

recovery regulations in such a manner that the violations could 

have affected the accuracy of a performance or reverification test. 

The tester shall cease conducting any performance or reverification 

test after receiving the second notice of violation until such time 

that the tester has successfully re-completed the District Tester 

Orientation class. 

(I) Not committed more than three violations of subparagraph 

(e)(3)(A) of this rule or CARB vapor recovery regulations in such 

a manner that the violations could have affected the accuracy of a 

performance or reverification test during any 12-month period. 

(4) Notwithstanding subparagraph (e)(3)(B), the owner/operator of a gasoline 

transfer and dispensing facility that has failed a reverification test or 

portions thereof may retest the facility prior to resuming operation 

provided that the person conducting the tests has complied with one of the 

following: 

(A) Notify the District by telephone or other District approved methods 

and obtain a confirmation number at least 12 hours prior to 

retesting (at least six of the hours shall be regular District business 

hours); or 

(B) When all necessary repairs are performed during the same day the 

facility has failed any of the applicable reverification tests, the 

owner/operator may retest the facility on the same day without renotification, provided that the reasons for the test failure and any 

repairs performed are properly documented in the test reports and 

the repair logs pursuant to subparagraphs (e)(6)(B) and (e)(6)(C). 

(5) The owner/operator shall not operate or resume operation of a gasoline 

transfer and dispensing facility, unless the facility has successfully passed 

the applicable performance or reverification tests. Notwithstanding the 

above, when a dispenser associated with any equipment that has failed a 

reverification test is isolated and shut down, the owner/operator may 

continue operation or resume operation of the remaining equipment at the 

facility, provided that test results demonstrate that the remaining 

equipment is in good operating condition. All test results and the method 

of isolating the defective equipment shall be documented in the test 
Rule 461 (Cont.) (Amended April 6, 2012)
