AltaGas closes $46 million Edmonton Ethane Extraction Plant acquisition and becomes operator

August 25, 2004

CALGARY--(CCNMatthews - Aug. 25) - AltaGas Income Trust (AltaGas or the 
Trust) (TSX:ALA.UN) announced today that it has closed the acquisition of a 
48 2/3 percent interest in the Edmonton Ethane Extraction Plant (EEEP) from 
BP Canada Energy Resources Company ("BP"). The effective date of the 
acquisition is January 1, 2004. After adjusting for the economic benefit from 
the effective date to closing, the purchase price paid by AltaGas for the 
facility was approximately $42.5 million. In connection with the acquisition 
AltaGas has employed BP's employees at EEEP and will immediately assume 
operatorship of the plant.

EEEP straddles the ATCO Gas and Pipelines Ltd. system which transports 
natural gas into the City of Edmonton and the Ft. Saskatchewan area. A long 
term gas supply contract provides a secure feedstock supply to EEEP. EEEP is 
directly connected to the Alberta Ethane Gathering System, and to BP's Co-Ed 
NGL pipeline, providing safe and reliable outlets for the plant's products.

The plant has a licensed gross inlet capacity of 390 Mmcf/d of natural gas 
and gross natural gas liquids (NGLs) production of approximately 15,000 
Bbls/d of specification ethane and 6,000 Bbls/d of propane-plus product. 
AltaGas' share of the plant's products will be sold under long term 
contracts. The addition of EEEP will increase AltaGas' total net inlet 
extraction capacity to 539 Mmcf/d and total ethane and NGLs production to 
approximately 19,500 Bbls/d.

David Cornhill, Chairman and Chief Executive Officer said, "We now have 
ownership interests in four of the nine deep cut extraction plants in 
Alberta. With the addition of EEEP, we expect our extraction business annual 
operating margin will grow to be in the range of our natural gas distribution 
and transmission businesses." Mr Cornhill added, "We are excited by the 
opportunities presented as operator of the EEEP facility and by the addition 
of the EEEP employees. The expertise of the EEEP employees combined with the 
expertise of our existing 500 plus employees strengthens our position as a 
full midstream service provider and better positions us to capture
