Yesterday, I was with a small group from Cheung Chau who sat in public viewing room for meeting by EIA sub-committee of the Advisory Committee on the Environment, as they discussed environmental impact assessment for waste incinerator to be sited at Tsang Tsui, Tuen Muen District, or an artificial island to be constructed off Shek Kwu Chau, just west of Cheung Chau. Watched proceedings on a couple of tvs; only public session was presentations, then questions and answers.
