9. Other than the use stage, the life cycle stages of the machinery used throughout the

 deconstruction or demolition process were not considered.

10. Sources of emissions included from the creation of virgin timber were harvesting,

 transporting the wood, milling the wood, and transporting the lumber to the

 construction site.

11. The data collected at the barracks in Ft. McClellan are applicable to all other

 barracks within U.S. EPA Region 4.

12. Methods for asbestos abatement and lead assessment are the same whether for

 demolition or deconstruction. The wood deposited into the landfill was untreated

 chemically, but most of it was painted with lead-based paint. Wood coated with

 lead-based paint produces lead-contaminated leachate; however; the effects of this

 wood were not accounted for in the leachate because there was the same amount in

 each barrack. Because the landfill is unlined, the leachate from all other materials

 contained within the barracks was accounted for using data reported in Jamback

 and Townsend (2004), the only available resource for this type of data.

13. The source of electricity was assumed to be the average U.S. mixture of 56% coal,

 21% nuclear, 10% hydropower, 10% natural gas, and 3% crude oil. The safety

 concerns of spent nuclear fuel were not considered.

 Sensitivity Analysis

 Assumptions and variables that were tested for their sensitivity to model impacts

included the time spent to both deconstruct and demolish the barracks, the distances the

workers traveled, the distances the materials and machinery were transported, the

recycling of the steel, and the time requirements for preparation of the materials for reuse.
