ii PLEASE NOTE

Addenda to this Guide will also be issued periodically to enable users to keep the Guide up-to-date

by replacing the pages that have been revised with the new pages. It is advisable, however, that

pages which have been revised be retained so that the chronological development of the Federal

Regulations and the Guide is maintained.

CAUTION

As part of document purchase, GPTC (using AGA as Secretariat) will try to keep purchasers

informed on the current Federal Regulations as rel eased by the Department of Transportation (DOT).

This is done by periodically issuing addenda to update both the Federal Regulations and the guide

material. It is the responsibility of the purchaser to obtain a copy of any addenda. Addenda are

posted on the Committee’s webpage at www.aga.org/gptc. The GPTC assumes no responsibility in

the event the purchaser does not obtain addenda. The purchaser is reminded that the changes to

the Regulations can be timely noted on the Federal Register's web site.
