Whether the foreign owned company can get permission to mine arsenic laced fill jeopardizing Maury Island aquifer, Highline Aquifer and possibly the Vashon Island aquifer also needs to be established to determine feasibility. Also assumed pit run to be 3000 lbs per cubic foot. Considering all the cost and availability fill issues that have arisen subsequent to the release of the SEIS, other alternatives need to be seriously considered. I believe the risk to the world's food chain is greatest when destroying Sea-Tac's wetlands due to their close proximity to Puget Sound and their already marginal functionality. Airports should not exceed practical capacity.
Theoretical capacity is normally economically unacceptable.
See my SEIS comments for references. Angle Lake was lower than the residents have ever seen it and feared losing it. While at Miller Creek between 8 PM and 9 PM on 11 April 1998, there was visible pollution on the surface. By rocks it had accumulated into piles at least 1 inch by 14 inches wide. The creek was covered with these floating circles that were obvious in the moonlight.
