NECESSITY, FUNCTION, AND CONFORMITY:
KRS
224.10-100 requires the Environmental and
Public Protection Cabinet to prescribe administrative regulations for the
prevention, abatement, and control of air pollution.
42
U.S.C. 7410 likewise requires the state to
implement standards for national primary and secondary ambient air quality.
This administrative regulation provides for the control of volatile organic
compound emissions from existing service stations.
Section 1. Definitions. As used in this
administrative regulation, all terms not defined in this section shall have the
meaning given to them in
401 KAR
61:001.
(1)
"Affected facility" means the gasoline storage tanks at a service
station.
(2) "Classification date"
means June 6, 1979.
(3) "Service
station" means a public or private establishment except farms which dispenses
gasoline into vehicle fuel tanks.
(4) "Submerged fill pipe" means a fill pipe
the discharge of which is entirely submerged when the liquid level is six (6)
inches above the bottom of the tank; or when applied to a tank which is loaded
from the side, shall mean a fill pipe the discharge opening of which is
entirely submerged when the liquid level is two (2) times the fill pipe
diameter above the bottom of the tank.
(5) "Vapor balance system" means a system
which conducts vapors displaced from storage tanks during filling operations to
the storage compartment of the transport vehicle delivering the fuel.
(6) "Vent line restriction" means:
(a) An orifice of one-half (1/2) to
three-quarters (3/4) inch inside diameter;
(b) A pressure-vacuum relief valve set to
open at not less than eight (8) oz. per square inch pressure and not less than
one-half (1/2) oz. per square inch vacuum unless a different vacuum relief
setting is required by safety or fire authorities; or
(c) A vent shutoff valve which is activated
by connection of the vapor return hose.
Section 2. Applicability. This administrative
regulation shall apply to each affected facility commenced before the
classification date defined in Section 1 of this administrative regulation
which is located in a county or portion of a county which is designated ozone
nonattainment, for any nonattainment classification except marginal, under
401 KAR
51:010.
Section

(1) The
owner or operator of an affected facility shall install, maintain, and operate
the following devices:
(a) Submerged fill
pipe;
(b) Vent line restriction on
the affected facility vent line; and
(c) Vapor balance system and vapor tight
connections on the liquid fill line and the vapor return line. The
cross-sectional area of the vapor return hose must be at least fifty (50)
percent of the liquid fill hose, and free of flow restrictions to achieve
acceptable recovery. The size and design of the vapor return line and
connections, including coaxial systems, are subject to the approval of the
cabinet.
(d) If the gasoline
storage tank is equipped with a separate gauge well, a gauge well drop tube
shall be installed which extends within six (6) inches of the bottom of the
tank.
(2) The owner or
operator may elect to use an alternate control system if that system can be
demonstrated to the cabinet's satisfaction to achieve an equivalent control
efficiency.
(3) The owner or
operator shall not allow any transport vehicle to deliver fuel to an affected
facility until the transport vehicle is properly connected to the vapor balance
system or alternate control system.
Section 4. Compliance Timetable.
(1) Affected facilities which were subject to
this administrative regulation as in effect on December 3, 1980, shall have
achieved final compliance upon start-up.
(2) The owner or operator of an affected
facility which becomes subject to this administrative regulation because it is
located in a county or portion of a county previously designated nonurban
nonattainment or redesignated in
401 KAR
51:010 after November 15, 1990, shall comply with this
administrative regulation in the following manner;
(a) Facilities with monthly throughput of
100,000 gallons or more of gasoline shall comply within one (1) year of
February 8, 1993.
(b) Facilities
with a monthly throughput between 10,000 and 100,000 gallons, shall comply
within two (2) years of February 8, 1993.
(c) Facilities shall be considered to comply

into effect by the date of compliance.
Section 5. Exemptions. An affected facility
shall be exempt from the provisions of Section 3 of this administrative
