6V. “Gasoline vapor line liquid blockage testing (herein referred to as liquid blockage testing)” refers to the injection of nitrogen in place of gasoline vapor into the gasoline vapor line between the gasoline pump and the gasoline tank in order to measure the pressure drop produced in the line and thereby determine the ability of gasoline droplets to flow back to the gasoline tank.

7VI. “Refueling gun air intake volume and fuel filling volume ratio testing (herein referred to as the air to liquid volume ratio testing)” refers to the determination of the ratio between the volume of air taken in while filling gasoline through the refueling gun and the volume of filled gasoline.

8VII. “Gasoline vapor line pressure loss leak testing (herein referred to as vapor leak testing)” refers to gas-tightness testing of a gasoline vapor recovery facility’s gasoline vapor lines.

A gas station’s gasoline refueling guns and storage tanks shall be equipped with recovery facilities.

1A newly-established gas station shall submit the following documents to the local competent authority with a gasoline vapor recovery facility establishment application after obtaining a construction permit and before reporting the start of construction work.

2I. A photocopy of the construction permit

3II. A photocopy of a construction preparation permit issued by the industry competent authority or other relevant verification document

4III. A gasoline vapor recovery facility establishment plan (herein referred to as the plan) containing the following items:

5A. Basic information concerning the gas station

6B. The gasoline vapor recovery facilities and facility design drawings

7C. Type of refueling gun recovery equipment

8D. Liquid blockage testing steps or procedures; expected testing dates

9E. Air to liquid volume ratio testing steps or procedures; expected testing dates

1After accepting an application in the foregoing article, the industry competent authority shall complete a documentary review of the plan within fourteen days. The competent authority shall notify the enterprise to proceed with gasoline vapor line burial and relevant testing after the application passes review. If the plan or related documents are incomplete or fail to pass review, the competent authority shall immediately notify the enterprise to make corrections or improvements within a limited period. The number of days for making corrections shall not be included within the review period, but the total number of days for making corrections may not exceed ninety days.

2Liquid blockage testing shall be performed after the completion of gasoline vapor line burial in the foregoing paragraph. The competent authority shall be notified five days prior to testing, and the competent authority may send personnel to supervise testing. The gas station shall record the test results and submit them to the competent authority for review within fifteen days after completion of testing. The competent authority shall issue verification documents only after checking that the results comply with the regulations.

Newly-established gas stations shall complete installation of gasoline vapor recovery facilities and air to liquid volume ratio and gasoline vapor leak testing within six months after obtaining a business license respectively. All gas stations shall record the testing results and submit them to the local competent authority for reference within fifteen days after completion of testing.

1The maximum pressure drop found in liquid blockage testing of gasoline vapor lines from gasoline pumps to gasoline tanks at newly-established gas stations shall comply with the following regulations:

1When local competent authorities perform air to liquid volume ratio testing of gas station refueling guns, the number of sampled and tested samples shall be at least one-half of the number of refueling guns of each gasoline pump. The gas station shall be deemed to have been failed when any of the following situations involving test results apply:

21.The number of refueling guns meeting the air to liquid volume ratio test standards in the foregoing article is less than 70% of the total number of refueling guns tested.

32.When the number of refueling guns meeting air to liquid volume ratio test standards in the foregoing article is at least 70% of the refueling guns tested, the refueling guns that fail to meet the passing standards shall include those for which improvements have not been completed on time after the competent authority has ordered improvement within a limited time period.

4The air to liquid volume ratio test of the sampled and tested refueling guns provided for in the foregoing paragraph may be performed by volumetric instrument or differential pressure instruments. The methods determining the test results which fail to meet the test standards are set forth below:

51.Tested by volumetric instrument: Where the first detection value is lower or higher than the test standards within 10%, the test shall be consecutively conducted twice, and the value calculated by averaging the three test results (round off to the second decimal place) is still lower or higher than the test standards.

62.Tested by differential pressure instrument:

1Gas stations shall themselves perform, or commission professional testing personnel to perform vapor leak testing once every two years. Testing shall be performed during the period from one month before to one month after the month of the previous testing. Each refueling gun shall be subjected to air to liquid volume ratio testing at least once during the first half and also during the second half of each year. The interval between two consecutive tests shall be at least three months. The local competent authority may, when necessary, request a gas station to increase the frequency of testing.

2If the average amount of gasoline dispensed at a gas station is less than 200 kiloliters per month for three consecutive months, after the gas station has requested and obtained the competent authority’s approval, the frequency of vapor leak testing may be reduced to once every three years and the frequency of refueling gun air to liquid volume ratio testing may be reduced to once each year, where the interval between two consecutive tests shall be at least six months. However, testing shall be handled in accordance with the regulations of the foregoing paragraph when the amount of gasoline dispensed at a gas station during any one quarter exceeds 600 kiloliters.

3Gas stations that have received approval in accordance with the regulations of the foregoing paragraph shall report to the local competent authority for future reference the amount of gasoline dispensed during each month of the previous quarter before the end of each January, April, July, and October. Testing shall be handled in accordance with the regulations of Paragraph 1 when a gas station fails to report in accordance with the regulations.

4A gas station that has failed air to liquid volume ratio testing or vapor leak testing performed in accordance with the regulations of Paragraph 1 shall complete improvements within 20 days; a gas station that cannot complete improvements by the deadline shall apply to the local competent authority for an extension by the deadline.

The results of improvement, repair, and testing performed in accordance with these Regulations shall be recorded and preserved for two years for reference.

The central competent authority or a testing organization commissioned by the central competent authority that has passed training and received a qualification certificate shall perform professional testing of gas station gasoline vapor recovery facilities.

These Regulations shall take effect on the date of enforcement.
