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 bulk gasoline plants.
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 a bulk gasoline plant.
(2) "Bulk gasoline plant" means a facility
for the storage and dispensing of gasoline that employs tank trucks, trailers,
or other mobile nonmarine vessels for both incoming and outgoing gasoline
transfer operations.
(3) "Gasoline"
means a petroleum distillate having a Reid vapor pressure of four (4.0) pounds
per square inch or greater used as a fuel for internal combustion
engines.
(4) "Bottom-fill system"
means a system of filling transport vehicle tanks through an opening that is
flush with the bottom of the transport vehicle tank.
(5) "Vapor balance system" means a
combination of pipes or hoses which create a closed system between the vapor
spaces of an unloading tank and a receiving tank such that vapors displaced
from the receiving tank are transferred to the tank being unloaded.
(6) "Submerged fill tube system" means a fill
tube the discharge of which is entirely submerged when the liquid level is six
(6) inches above the bottom of the transport vehicle tank.
(7) "Classification date" means June 29,
1979.
(8) "Transport vehicle" means
tank trucks, trailers, railroad or tank cars.
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
3. Standard for VOCs.
(1) The
owner or operator of an affected facility shall install, maintain, and operate:
(a) Stationary storage tank control devices
according to
401 KAR
59:050 or
401 KAR
61:050.
(b) A vapor balance system or an equivalent
control approved by the cabinet and the U.S. EPA for:
1. Filling of stationary storage tanks from
transport vehicle tanks; and
2.
Filling of transport vehicle tanks from stationary storage tanks.
(c) For loading into transport
vehicle tanks either:
1. A submerged fill tube
system; or
2. A bottom-fill
system.
(2) The
vapor balance system shall be equipped with fittings which are vapor tight and
automatically close upon disconnection so as to prevent the release of organic
material.
(3) The cross-sectional
area of the vapor return hose shall be at least fifty (50) percent of the
cross-sectional area of the liquid fill line and free of flow
restrictions.
(4) Transport vehicle
tank hatches shall be closed at all times during loading operations.
(5) There shall be no leaks from the
pressure-vacuum relief valves and hatch covers of the stationary storage tanks
during loading.
(6) The pressure
relief valves on storage vessels and tank trucks or trailers shall be set to
release at no less than seven-tenths (0.7) psig unless a lower setting is
required by applicable fire codes.
(7) The owner or operator shall not load
gasoline into any transport vehicle or receive gasoline from any transport
vehicle which does not have proper fittings for connection of the vapor balance
system, nor shall the owner or operator load or receive gasoline unless the
vapor balance system is properly connected and in good working order. Except as
provided in subsection (8) of this section the fittings on the transport
vehicle tanks shall be vapor tight and automatically close upon disconnection
so as to prevent the release of organic material.
(8) The following shall apply to the loading
of a transport vehicle tank by means of a submerged fill tube system:
(a) When inserted into the tank, the
submerged fill tube system shall form a vapor tight seal with the
tank.
(b) Tank hatches are to be
opened only for the minimum time necessary to insert or remove the submerged
fill tube system.
(9) No
owner or operator shall permit gasoline to be spilled, discarded in sewers,
stored in open containers, or handled in a manner that would result in
evaporation.
(10) No owner or
operator of a bulk gasoline plant subject to this administrative regulation
shall allow loading of a tank truck unless the following provisions are met:
(a) The tank truck has a valid Kentucky
pressure-vacuum test sticker as required by
401 KAR
63:031 attached and visibly displayed;
(b) The vapor balance system and associated
equipment are designed and operated to prevent gauge pressure in the tank truck
from exceeding 450 mm water (eighteen (18) in. water) and prevent vacuum from
exceeding 150 mm water (six (6) in. water);
(c) A pressure tap or equivalent system as
approved by the cabinet is installed on the vapor balance system so that a
liquid manometer can be connected by an inspector to the tap in order to
determine compliance with paragraph (b) of this subsection. The pressure tap
shall be installed by the owner or operator as close as possible to the
connection with the delivery tank, and shall consist of a one- quarter (1/4)
inch tubing connector which is compatible with the use of three-sixteenth
(3/16) inch inside diameter plastic tubing; and
(d) During loading operations there is no
reading greater than or equal to 100 percent of the lower explosive limit (LEL,
measured as propane) at a distance of two and five-tenths (2.5) centimeters
around the perimeter of a potential leak source associated with the vapor
balance system of a bulk gasoline plant as detected by a combustible gas
detector using the test procedure referenced in Section 5 of this
administrative regulation.
Section 4. The owner or operator may elect to
use an alternate control system if it can be demonstrated to the cabinet's
satisfaction that the alternate system shall achieve equivalent control
efficiency.
Section 5. Compliance.
The test procedure as defined in Appendix B to "Control of Volatile Organic
Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems" (OAQPS
1.2-119, U.S. EPA, Office of Air Quality Planning and Standards), which has
been incorporated by reference in
401 KAR
50:015, or an equivalent procedure approved by the
cabinet, shall be used by the cabinet to determine compliance with the standard
prescribed in Section 3(10)(d) of this administrative regulation during
inspections conducted pursuant to
KRS
224.10-100(10).
Section 6. Compliance Timetable.
(1) Affected facilities which were subject to

achieved final compliance.
(2) The
owner or operator of an affected facility that becomes subject to this
administrative regulation on or after September 28, 1994 shall be required to
