1. No owner or operator shall transfer, allow the transfer, or provide equipment for the transfer of gasoline, and no other person shall transfer gasoline from a gasoline delivery tank equipped with a vapor recovery system into a stationary storage tank at a retail service station unless an ARB-certified Phase I vapor recovery system is installed on the stationary storage tank and used during the transfer. The ARB-certified Phase I vapor recovery system shall meet a 90% vapor recovery efficiency as determined by ARB Test Method 2-1 or equivalent.
2. The provisions of Rule 1-400 (a) (1) shall not apply to:
1. An existing retail service station with a gasoline throughput of 480,000 or fewer gallons during the calendar year 1988. If during any calendar year thereafter the gasoline throughput at any existing retail service station exceeds 480,000 gallons, this exemption shall cease to apply commencing with the first day of the following calendar year.
2. A transfer to a stationary storage tank at an existing retail service station which receives gasoline exclusively from delivery tanks that are not required to be equipped with vapor recovery systems.
3. At the time of modifications at any existing retail service station of any throughput, ARB-certified Phase I vapor recovery systems shall be installed and used thereafter on all of the station facilities, except those stations which are exempt from the Phase I requirement by Rule 1-400 (a) (2) (B).

(b) PHASE II VAPOR RECOVERY SYSTEM REQUIREMENTS.

1. No owner or operator shall transfer, allow the transfer or provide equipment for the transfer of gasoline from a stationary storage tank at a retail service station into a motor vehicle fuel tank unless an ARB-certified Phase II vapor recovery system is installed and used during the transfer. The ARB-certified Phase II vapor recovery system shall meet a 90% vapor recovery efficiency as determined by ARB Test Method 2-1 or equivalent.
2. The provisions of Rule 1-400 (b)(1) shall not apply to an existing retail service station which qualifies under the throughput exemption for Phase I requirements of Rule 1-400 (a) (2) (A).
3. At the time of modifications at any existing retail service station of any throughput, ARB-certified Phase II vapor recovery systems shall be installed and used thereafter on all of the station facilities.
