CALGARY, ALBERTA--(CCNMatthews - May 24, 2007) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced that it will construct a new gas processing facility and associated gathering and sales lines near Acme, Alberta, approximately 85 kilometres northeast of Calgary. Capable of processing 10 Mmcf/d of natural gas, the facility will process coal bed methane (CBM) for Ember Resources Inc. (Ember). The construction of the pipelines and facility is expected to cost approximately $11 million.

"We are pleased to partner with Ember, an existing AltaGas customer," said David Cornhill, Chairman, President and CEO of AltaGas. He added, "The Acme project is in a prolific CBM area with significant reserves potential. This project is part of the $50 million AltaGas expects to spend in our Field Gathering and Processing segment this year, over and above the 90 Mmcf/d Noel Pipeline and Pouce Coupe gas processing plant expansion project we announced in April."

AltaGas will own 100 percent of the Acme plant, which will consist of 21 kilometres of 10-inch plastic gathering pipelines and 10 kilometres of 6-inch steel sales pipelines, as well as compression and dehydration facilities. The Trust will operate the plant, which is expected to be in service in the fourth quarter of 2007. The project is subject to provincial regulatory approvals.

Underpinning the project is a binding agreement for firm gas gathering and processing capacity with Ember, including a dedication of reserves provision which covers approximately 165 sections of land.
