Gas Station Gasoline Vapor Recovery Facility Management Regulations Article 9

Gas 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.If 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.Gas 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.A 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.A gas station refueling gun that is not in use for six months or more due to some reason must pass air-to-liquid volume ratio testing; a report must be made to the local competent authority before the refueling gun can be used again.
