AltaGas Income Trust to Build New Pipeline From B.C. and to Expand Pouce Coupe Plant by 90 Mmcf/d

April 10, 2007

CALGARY, ALBERTA--(CCNMatthews - April 10, 2007) - AltaGas Income Trust (TSX:ALA.UN) (AltaGas or the Trust) today announced that it will construct a new natural gas pipeline to bring 90 Mmcf/d of natural gas from the Noel region of British Columbia to its Pouce Coupe gas processing facility in northwest Alberta. AltaGas will also add 90 Mmcf/d of sour gas processing capability to the Pouce Coupe facility, which currently processes approximately 8 Mmcf of sweet gas daily. The acid gas recovered from the sour gas processed at the Pouce Coupe facility will be re-injected into existing wells in the vicinity of the facility, minimizing the facility's sulphur emissions. The Noel pipeline construction project and the Pouce Coupe facility expansion project are in total expected to cost approximately $90 million.

"AltaGas is excited about the Noel pipeline construction project and the Pouce Coupe facility expansion project," said David Cornhill, Chairman, President and CEO of AltaGas. He added, "The Noel region is an under-developed area with significant potential for reserves of sour gas. These projects will provide producers in the Noel region with the most competitive, economic and environmentally friendly option to process their gas. The Pouce Coupe facility will use acid gas injection to minimize the emissions that result from gas processing."

"These projects fit AltaGas' strategy for our Field Gathering and Processing segment and when completed should increase our throughput in this segment by over ten percent."

Underpinning the project is a binding contract for firm gas gathering and processing capacity with Devon Canada Corporation (Devon). Devon has active development plans for drilling wells within the gathering area of the pipeline system. The binding contract is subject to certain economic and regulatory conditions precedent. Additional capacity in the Noel pipeline and the expanded Pouce Coupe facility is available for other gas producers.

As currently proposed, a 12-inch pipeline will be built from the north Noel region. The diameter of the pipeline will increase to 16 inches for the portion crossing the Alberta-B.C. border and ending at the Pouce Coupe plant in Alberta.

The projects are subject to provincial and federal regulatory approvals, are expected to begin construction in mid-2007 and are expected to be in service by April 2008.
