AltaGas Submits Harmattan Co-stream Application to Regulators

April 23, 2009

CALGARY, ALBERTA--(Marketwire - April 23, 2009) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) announced today that it has submitted its application for the Harmattan Co-stream Project to the Alberta Energy Resources Conservation Board (ERCB).  "The Co-stream Project will use spare, highly efficient ethane and natural gas liquids (NGL) extraction capacity at the Harmattan Complex deep cut facilities to produce a cost effective, stable long-term supply of ethane to Alberta's petrochemical industry," said David Cornhill, Chairman and CEO of the Trust. "It will also provide a competitive supply of propane, butane and condensate to local Alberta markets."  If approved, the Co-stream Project would allow 250 million cubic feet per day (Mmcf/d) of rich, sweet natural gas sourced from the NGTL Western Alberta System to be processed using spare capacity at the Harmattan Complex to recover ethane and NGLs. The Project involves constructing and operating two new large-diameter high-pressure sweet natural gas pipelines and one small-diameter high vapour pressure product pipeline, as well as modifying existing equipment for processing gas at the Complex. The application was submitted under the Trust's indirect, wholly-owned Taylor Processing Inc. entity.  The current throughput at the Harmattan Complex is approximately 150 Mmcf/d, or 30 percent of the licenced plant capacity. Upon approval from the ERCB, construction of the project would take approximately 14 months to complete. The project is expected to begin contributing to operating income in late 2010. Capital cost estimates for the Co-stream Project are $100 to $120 million.  AltaGas Income Trust is one of Canada's largest and fastest growing energy infrastructure organizations.
