ACCESS ARRANGEMENT INFORMATION FOR PRINCIPAL AND WESTERN TRANSMISSION PIPELINES BY 
TRANSMISSION PIPELINES AUSTRALIA PTY LTD AND 
TRANSMISSION PIPELINES AUSTRALIA (ASSETS) PTY LTD

1.	Introduction
Energy Projects Division of the Victorian Department of Treasury and Finance (“EPD”) on behalf of Transmission Pipelines Australia Pty Ltd and Transmission Pipelines (Assets) Pty Ltd (together “TPA”) submitted to the Australian Competition and Consumer Commission (“ACCC”):
•	on 3 November 1997 Access Arrangement Information (“original AAI”);
•	on 13 March 1998 supplementary Access Arrangement Information (“supplementary AAI1”); and
•	on 16 March 1998 additional supplementary Access Arrangement Information (“supplementary AAI2”).
On 6 October 1998, the ACCC issued its Final Decision (“Final Decision 1”) on the Access Arrangements for TPA.
This Access Arrangement Information (“final AAI”) is submitted together with the revised Access Arrangements for TPA as required by Final Decision 1.
The final AAI must be read together with the original AAI, supplementary AAI1 and supplementary AAI2.
The final AAI updates all relevant tables contained in the original AAI, supplementary AAI1 and supplementary AAI2 having regard to Final Decision 1.
Words and phrases defined in the revised Access Arrangements, original AAI, supplementary AAI1 and supplementary AAI2, as the case may be, have the meaning given to them in those documents unless the context otherwise requires.
Except as varied by Final Decision 1, or except where expressly set out in the final AAI or revised Access Arrangements, as the case may be, the statements of methodology contained in the original AAI, supplementary AAI1 or supplementary AAI2 apply to the tables contained in the final AAI.
All financial values in the tables are in nominal terms unless otherwise stated.
