can use parametric estimating to define the material composition within each vessel and the estimated value of recyclable materials that were dumped at sea.
Referencing Appendix B, the 2001 Rand Report recovery indices, and the current commodity price index, one can estimate the total material value lost over the past decade to the Federal government’s ocean dumping programs. With 95 vessels weighing a combined 674,318 tons, only 9% of which was waste, 613,629 tons of material was recyclable, worth an estimated
government dumped more than half a billion dollars at sea without accounting for any material value loss. On top of this astonishing figure, the Navy also paid substantial amounts to conduct each ocean dumping exercise.
The USS ARLINGTON is under construction using steel salvaged from the September 11, 2001 attack on the Pentagon. The sister ship, USS NEW YORK, was partially constructed of salvaged steel from the Twin Tower site, and the USS SOMERSET was partially constructed using steel from the crash site of Flight 93. Reusing salvaged scrap materials from retired naval vessels to build the new fleet would not only give tribute to those lost and those who served, but it would also reduce environmental impacts associated with primary metals mining to respect the needs of future generations.

Air Pollution Costs
The ocean disposal of naval vessels discards valuable material that would otherwise be recycled to reduce virgin resource extraction and refining and related CO2 emissions, as
discussed in the previous section. Under a cap and trade model, carbon is a factor in assigning monetary value to various activities. Increasing value is assigned to activities or products that
