Kentucky Administrative Regulations › Title 401 - ENERGY AND ENVIRONMENT CABINET - DEPARTMENT FOR ENVIRONMENTAL PROTECTION › Chapter 65 - Mobile Source-Related Emissions › Section 401 KAR 65:005 - Liquefied petroleum gas carburetion systems

Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO: KRS Chapters 224, 234
NECESSITY, FUNCTION, AND CONFORMITY:
				KRS
				234.321 requires the Environmental and Public
				Protection Cabinet to establish emission standards for liquefied petroleum gas
				carburetion systems. This administrative regulation complies with that
				requirement.
Section 1. General
			 Provisions.
(1) Applicability. This
			 administrative regulation is applicable only to motor vehicles utilizing
			 liquefied petroleum gas for fuel which are required to be equipped with
			 carburetion systems approved by the cabinet in order to be eligible for tax
			 exemptions as set forth in
			 KRS
			 234.321.
(2) Definitions. As used in this
			 administrative regulation, all terms not defined herein shall have the meaning
			 given them in
			 401 KAR
			 50:010.
(a) "Exhaust
			 emissions" means substances emitted to the atmosphere from any opening
			 downstream from the exhaust port of a motor vehicle engine.
(b) "Light-duty vehicle" means any motor
			 vehicle either designed primarily for transportation of property and rated at
			 6,000 pounds gross vehicle weight or less or designed primarily for
			 transportation of persons and having a capacity of twelve (12) persons or
			 less.
(c) "Heavy-duty vehicle"
			 means any motor vehicle either designed primarily for transportation of
			 property and rated at more than 6,000 pounds gross vehicle weight or designed
			 primarily for transportation of persons and having a capacity of more than
			 twelve (12) persons.
(d) "Gross
			 vehicle weight" means the manufacturer's gross weight rating.
(3) Vehicle modification to use
			 liquefied petroleum gas.
(a) In addition to
			 all other standards or requirements imposed, any modification of a motor
			 vehicle which allows that vehicle to use liquefied petroleum gas (LPG) for fuel
			 shall not in its operation and function, or malfunction:
1. Cause any emission into the ambient air of
			 any noxious or toxic matter that would not be emitted in the operation of such
			 motor vehicle or motor vehicle engine operating without such a modification;
			 or
2. Cause any unsafe condition
			 which may endanger the motor vehicle, or its occupants or other persons or
			 property.
(b) In cases
			 where a modification of a vehicle has been made which enables gasoline and/or
			 liquefied petroleum gas to be used as fuel, evidence satisfactory to the
			 cabinet must be presented to the cabinet that the modification will not cause
			 increased emissions by the vehicle when that vehicle is being fueled by
			 gasoline.
(c) The reactivity of the
			 exhaust gases must not be increased by any modification to a carburetion
			 system, which modification allows the use of liquefied petroleum gas as a
			 fuel.
(4) Application for
			 approval.
(a) An application for approval of
			 any carburetion system which uses liquefied petroleum gas may be made to the
			 cabinet by any manufacturer.
(b)
			 The application shall be in writing, signed by an authorized representative of
			 the manufacturer, and shall include the following:
1. Identification and description of the
			 carburetion systems, vehicles and engines with respect to which approval is
			 required.
2. A complete description
			 of all modifications and additions to the engine or vehicle.
3. Emission data on such vehicles and engines
			 tested in accordance with the applicable exhaust emission test
			 procedures.
4. A description of
			 tests performed to ascertain compliance with the general standards, and the
			 result of such test.
5. A statement
			 listing the name and location of the testing facility, its qualifications to
			 perform such tests, a certification that such testing facility was at the time
			 the test was performed, approved to conduct such tests by the U. S.
			 EPA.
6. A statement of recommended
			 maintenance procedures and equipment necessary to assure that the carburetion
			 system, vehicle and engine in operation conform to the requirements of this
			 administrative regulation, and a description of the program for training of
			 personnel for such maintenance.
7.
			 An agreement that any modifications made to the system in the field will be
			 properly identified and reported to the cabinet. To meet this requirement, the
			 model number shall be permanently marked on the carburetor. An adhesive label
			 listing the information in subparagraphs 8 to 12 of this paragraph shall be
			 furnished for installation on the air cleaner.
8. Manufacturer's name and address.
9. Accepted by the Environmental and Public
			 Protection Cabinet for use on engine sizes ___ cubic inch to __ cubic
			 inch.
10. Spark timing.
11. Idle speed.
12. Mixture adjustment (if used).
(c) If, after a review of the data
			 submitted by the manufacturer, the cabinet determines that a carburetion system
			 to use liquefied petroleum gas conforms to this administrative regulation, it
			 will issue an approval with respect to such system.
