APA  Group (ASX:APA) notes that the Economic Regulation Authority (ERA) of Western Australia has today released its final decision on the proposed 2010-2014 access arrangement for the Goldfields Gas Pipeline (GGP).  The reference tariff charges in the access arrangement apply to approximately 40 per cent of the annual revenue APA receives from the GGP.  

The final decision specifies ERA’s required revisions to the proposed access arrangement. APA's response to the final decision, which includes submitting a revised access arrangement, is due on 4 June 2010.  Following this, the ERA will make its final determination on whether or not to approve the revised access arrangement.  

While APA notes that the final decision is an improvement compared to the draft decision issued in November 2009, APA will work through the final decision document in full prior to considering its response.  

APA Managing Director Mick McCormack said:  "We require some time to examine the final decision fully, but our initial review indicates that the outcome will not materially impact APA's overall revenue."
