From reading the article, I think this community group is confused. The EA was specifically about the tunnel, their beefs seem to mainly be with the increased traffic at the airport. "CommunityAIR argues that the airport traffic is too high, creates noise pollution, and makes life generally miserable for those who live near the busy hub."... What does that have to do with the tunnel EA at all?!?! Calling a very specific EA a sham, when your real problem is with the airport itself, isn't going to gain you much credibility. It just makes you sound like a NIMBY group who has no idea how the process works, or how to go about actually getting change. It was just an EA, not a feasibility study. You don't need that much public participation to prove that a tunnel underneath a harbour is not going to significantly damage the environment.
