Mr. Barry Breslow 120 Ryder Avenue Dix Hills, New York 11746

Dear Mr. Breslow:

This responds to your recent letter asking for information concerning the Federal and State regulations that would be applicable to conversions of gasoline-powered vehicles to run on LP gas. I am enclosing a copy of a letter of interpretation the agency issued last August which discusses the Federal requirements and implications of such conversions. You will have to contact the individual States to find out any requirements they may have, however.

If you have any questions after reviewing the enclosed information, feel free to contact Hugh Oates of my staff at 202-426-2992.

Sincerely,

Frank Berndt Chief Counsel

Ms. Debra Weiner National Highway Traffic Safety Administration Office of Chief Counsel 400 7 Street, S.W. Washington, D.C. 20590

Dear Ms. Weiner:

The White Plains Office of the NHTSA suggested I contact you to verify the national and state regulations and certifications relating to LP gas conversions for automobiles and light trucks.

We are planning to introduce a "dual fuel" conversion for passenger type vehicles and light trucks. This conversion will retain the standard type gasoline system, and have a switching mechanism to change-over to the independent propane system.

It is our understanding that the propane system is not regulated by standard # 301-75, as the regulation only governs fuel with a boiling point above 32oF. (propane boils at -44oF.)

I would sincerely appreciate your earliest response as to what Federal/State regulations and certifications are necessary to properly introduce this product to the U.S. market.

Very truly yours,

Barry Breslow 120 Ryder Avenue Dix Hills, New York 11746
