309 SOURCE TESTING: 

309.1 Within 45 calendar days of the initial operation of a new or altered 

gasoline dispensing facility, the owner/operator shall conduct and 

successfully pass the source tests in accordance with the test methods 

specified in Section 600, and any additional tests required by the 

applicable CARB Executive Orders including the corresponding CARB 

approved Installation, Operation and Maintenance Manual and District 

Permits, to verify the proper installation and operation of Phase I and 

Phase II vapor recovery systems.

309.2 The owner/operator shall conduct and successfully pass the reverification 

tests in accordance with the test methods specified in Section 600, and any 

additional tests required by the applicable CARB Executive Orders 

including the corresponding CARB approved Installation, Operation and 

Maintenance Manual and District Permits, to verify the proper operation 

of the vapor recovery systems. The owner/operator of a gasoline 

dispensing facility with a Permit to Operate throughput limit of 4,000,000 

gallons per year or greater shall complete the reverification test 

semiannually. Each semiannual test shall be completed within 6 months of 

the previous successful test. No adjustments to the gasoline dispensing 

facility shall be made the day of the test and the test shall be conducted in 

an as-is-condition. Once non-compliance with a performance standard has 
Yolo-Solano AQMD

Revised January 14, 2015 Reg. II, Rule, 2.22, Page 15

been determined and documented, the facility may make the necessary 

adjustments to bring the facility back into compliance.

309.3 The owner/operator of a gasoline dispensing facility with a Permit to 

Operate throughput limit less than 4,000,000 gallons per year shall 

complete the reverification annually. Each annual test shall be completed 

within 12 months of the previous successful test. No adjustments to the 

gasoline dispensing facility shall be made the day of the test and the test 

shall be conducted in an as-is-condition. Once non-compliance with a 

performance standard has been determined and documented, the facility 

may make the necessary adjustments to bring the facility back into

compliance.

309.4 A person who conducts performance or reverification tests shall comply 

with all of the following:

a. Conduct tests in accordance with the applicable test methods 

specified in Section 600 and other CARB testing procedures. Tests 

shall be conducted using calibrated equipment meeting the 

calibration range and calibration intervals specified by the 

manufacturer.

b. Provide notification to the District at least 3 days prior to testing 

except for reverification tests conducted after a driveoff, provided 

that the person conducting the tests complies with all other 

applicable provisions of the rule.

required standards, and the name and signature of the person 

responsible for conducting the tests.

309.5 Notwithstanding Section 309.5.b, the owner/operator 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 at least 12 hours prior to retesting; or

b. When all necessary repairs are performed during the same day the 

facility has failed, the owner/operator may retest the facility on the 

same day without re-notification, 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 Sections 502.2 and 

502.3.

309.6 The owner/operator shall not operate or resume operation of a gasoline 

dispensing facility, unless the facility has successfully passed the 

applicable performance or reverification tests. Notwithstanding the above, 
Yolo-Solano AQMD

Revised January 14, 2015 Reg. II, Rule, 2.22, Page 16

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 

reports to be submitted to the APCO pursuant Section 502.3.

310 PROHIBITION OF USE: Whenever the Air Pollution Control Officer 

determines that a Phase II vapor recovery system, or any component thereof, 

contains a defect specified by the California Air Resources Board pursuant to 

Section 41960.2(c) of the California Health and Safety Code, the Air Pollution 

Control Officer shall mark such a system or component “Out of Order.” No 

person shall use or permit the use of such marked component or system until it 

has been repaired, replaced, or adjusted, as necessary, and the APCO has 

reinspected it or has authorized its use pending reinspection.

311 POSTING OF OPERATING INSTRUCTIONS: The owner/operator of each 

retail gasoline dispensing facility utilizing a Phase II system shall conspicuously 

post operating instructions for the system in the gasoline dispensing area. The 

instructions shall clearly describe how to fuel motor vehicles correctly with vapor 

recovery nozzles, and shall include a warning that topping off may result in 

spillage or recirculation of gasoline and is prohibited. Additionally the 

instructions shall include prominent display of the Yolo-Solano Air Quality 

Management District's or the California Air Resources Board's toll free telephone 

number for complaints. A dispenser that is never used to fuel motor vehicles shall 

have a sign posted on it restricting its use for motor vehicles. All required signs 

shall conform to the following:
