California Code of Regulations › Title 13 - Motor Vehicles › Division 2 - Department of the California Highway Patrol › Chapter 4 - Special Equipment › Article 2 - Compressed and Liquefied Gas Fuel Systems › Section 937 - Exemptions

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The Commissioner may grant exemptions from any of the
					 requirements of this article except those requirements governed by the
					 California Air Resources Board when, in his judgement, the request appears
					 reasonable or the results intended by these regulations can be accomplished by
					 alternate methods of compliance. However, no exemption will be granted if, in
					 the opinion of the Commissioner, the exemption would compromise the safety
					 requirements of these regulations. In addition, any exemption granted by the
					 Commissioner is nontransferable and may be rescinded at any time for cause. The
					 California Highway Patrol shall within 90 days of receiving a request for
					 exemption, respond in writing informing the requesting party whether the
					 exemption has been denied or granted. The reason(s) for denial of the request
					 will be included in the written response and the California Highway Patrol's
					 decision is final. No exemptions will be given for motor vehicles manufactured
					 after the effective date of Federal Motor Vehicle Safety Standards addressing
					 gaseous fuel systems.
(1) Application
				  for Exemption. An application for exemption shall be made in writing to the
				  Commissioner, and it shall include the following data:
Reason for requesting an exemption.
Alternate method(s) of compliance.
Make, model and identification number of the vehicle for
					 which the exemption is being requested.
The application shall be mailed to:
CALIFORNIA HIGHWAY PATROL
ENFORCEMENT SERVICES DIVISION
POST OFFICE BOX 942898
SACRAMENTO, CA 94298-0001
(2) Copy of exemption. A copy of any
				  exemption shall be carried in the vehicle(s) for which it was issued at all
				  times, and shall be presented for inspection upon demand by any authorized
				  representative of the Department.
