July 06, 2009

CALGARY, ALBERTA--(Marketwire - July 6, 2009) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced that it has entered into a Memorandum of Understanding (MOU) with NOVA Chemicals Corporation (NOVA Chemicals). As part of the proposed Harmattan Co-Stream Project, AltaGas is planning to process an initial 250 Mmcf/d of additional natural gas using spare capacity at the Harmattan Complex to extract ethane and natural gas liquids (NGL). Currently, AltaGas processes approximately 150 Mmcf/d at the Harmattan Complex.  "The Harmattan Co-Stream Project will allow AltaGas to realize an initial incremental 250 Mmcf/d of existing processing and extraction capacity at our highly efficient Harmattan Complex," said David Cornhill, Chairman and CEO of the Trust. "Furthermore, the Harmattan Co-Stream Project will expand the availability of valuable feedstock for Alberta's petrochemical industry, and retain extraction revenues and value in Alberta in a most economical manner."  The MOU provides that the definitive agreements between AltaGas and NOVA Chemicals would be for an initial term of 20 years, would have AltaGas deliver all liquids or co-stream gas products on a full cost-of-service basis to NOVA Chemicals, and would provide that all capital expenditures and operating costs related to the proposed project will be fully recovered through fees under normal operations. The MOU is subject to normal conditions precedent, including execution and delivery of mutually satisfactory definitive agreements between AltaGas and NOVA Chemicals, a favourable decision on the Harmattan Co-Stream application made by AltaGas and currently before the Alberta Energy Resources Conservation Board, and approval by the boards of directors of AltaGas and NOVA Chemicals.  The proposed Harmattan Co-Stream Project promotes responsible competition by creating a competitive option for shippers similar to the competitive environment at Empress, Alberta, where shippers have multiple extraction options.
