October 04, 2005

CALGARY--(CCNMatthews - Oct. 4) - AltaGas Income Trust (AltaGas or the Trust) (TSX: ALA.UN) announced today it will build a 15 MMcf/d sweet gas processing facility approximately 40 miles northwest of Clear Prairie, Alberta, extending its gathering and processing presence west of the sixth meridian. Construction of the $6 million Clear Prairie Gas Plant is expected to begin in early November, with commissioning anticipated in mid-December, subject to regulatory approvals being received.

Included in the cost to build the new processing facility is the acquisition of existing gathering lines and infrastructure from Warrior Energy Corporation (Warrior). The Clear Prairie Gas Plant will receive and process sweet natural gas from several active producers in the area and will include compression, dehydration and refrigeration.

Warrior has agreed to provide a term dedication that will underpin throughput at the facility. The plant is anticipated to be processing at capacity by spring 2006, and to be accretive to earnings.

David Cornhill, Chairman and CEO of AltaGas remarked, "I am excited by this significant expansion in northwest Alberta. The Clear Prairie Gas Plant showcases AltaGas' ability to grow internally and positions us to pursue further gathering opportunities in northwest Alberta and in British Columbia."

Marshal Thompson, Senior Vice President Gathering and Processing at AltaGas added, "There is significant activity in the Clear Prairie area of northwest Alberta. The construction of the Clear Prairie Gas Plant is in response to area producers' need for increased access to processing capacity."

The announcement of the Clear Prairie Gas Plant follows the September 30, 2005 announcement of plans to construct the 20 MMcf/d Princess Gas Plant, which will be connected to AltaGas' existing Bantry facility. AltaGas will spend $20 million on these two internal expansion opportunities.
