- Purpose. To comply with the Air Resources Board's airborne toxic control measure for emissions of benzene from
retail service stations as required by California Health and Safety Code Section 39666. This Rule does not apply
to service stations with an annual gasoline throughput of less than 120,000 gallons.
- Definitions. For the purposes of this rule, the following definitions shall apply:
- "ARB-certified vapor recovery system" means a vapor recovery system which has been certified by the
state board pursuant to Section 41954 of the Health and Safety Code.
- "Excavation" means exposure to view by digging.
- "Gasoline" means any organic liquid (including petroleum distillates and methanol) having a Reid
vapor pressure of four pounds or greater and used as a motor vehicle fuel or any fuel which is commonly or commercially
known or sold as gasoline.
- "Motor vehicle" has the same meaning as defined in Section 415 of the Vehicle Code.
- "Owner or operator" means an owner or operator of a retail service station.
- "Phase I vapor recovery system" means a gasoline vapor recovery system which recovers vapors during
the transfer of gasoline from delivery tanks into stationary storage tanks.

the fueling of motor vehicles from stationary storage tanks.
- "Retail service station" means any new or existing motor vehicle fueling service station subject
to payment of California sales tax on gasoline sales.
- "Existing retail service station" means any retail service station operating, constructed, or under
construction as of December 14, 1988.
- "New retail service station" means any retail service station which is not constructed or under construction
as of December 14, 1988.
- "Tank replacement" means replacement of one or more stationary storage tanks at an existing retail
service station or excavation of 50 percent or more of an existing retail service station's total underground liquid
piping from the stationary storage tanks to the gasoline dispensers.
- "Throughput" means the volume of gasoline dispensed at a retail service station.
- Phase I - Gasoline Loading into Stationary Tanks
- Requirements: No owner or operator shall transfer, permit 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.
- A transfer to a stationary storage tank with a capacity of less than 260 gallons.
- A transfer to a stationary storage tank used the majority of the time for the fueling of implements of husbandry
as defined in Division 16, Chapter 1, of the Vehicle Code.
- A transfer to a stationary storage tank used exclusively to fuel motor vehicles with a fuel capacity of five
gallons or less.
- 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.
- An existing retail service station with an annual station gasoline throughput from tanks other than those described
above of 450,000 or fewer gallons during 1987. If during any calendar year thereafter the gasoline throughput from
such tanks at the existing retail service station exceeds 450,000 gallons, this exemption shall cease to apply,
commencing with the first day of the following calendar year. However, at the time of tank replacement at an existing
retail service station with an annual station gasoline throughput of 120,000 gallons or more, ARB-certified Phase
I vapor recovery systems shall be installed and used thereafter on all of the station facilities that are not exempt
under Sections 2 (a), (b), (c), or (d).
- Permit fee: All retail service stations subject to this rule shall obtain an Authority to Construct/Permit
to Operate at the time of installation of Phase I equipment, and shall pay a fee in accordance with Regulation
III, Schedule 5.
- Phase II - Transfer of Gasoline into Vehicle Fuel Tanks
- Requirements: No owner or operator shall transfer, permit 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.
- Exemptions: An owner/operator seeking an exemption from any section of this rule must supply the APCO with
all information necessary for the APCO to determine whether such an exemption should be granted. A photo copy of
the owner's/operator's Franchise Tax Board report will be sufficient to meet this requirement. Owners/Operators
seeking exemption on throughput criteria must petition annually to renew such exemptions. All information must
be certified to be correct under penalty of perjury by the applicant and should be supplied to the District within
60 days of the start of each calendar year.
- A transfer of gasoline from a stationary storage tank which is exempt from Phase I requirements under Sections
C. 2 (a), (b), or (c).
- An existing retail service station which is exempt from Phase I requirements under Section C. 2 e.
- Correction of Defects: No owner or operator shall use or permit the use of any Phase II system or any component
thereof containing a defect identified in Title 17, California Administrative Code, Section 94006, Part III, Chapter
1, Subchapter 8:
