The final key body of data involves the operating costs for a refinery at each potential
site. Estimating these costs requires site visits by several members of the task force
to collect detailed information about local labor costs, taxes, and so forth. Comparisons
then are made with the operating costs of the current refineries to help refine these data.
In addition, the task force gathers information on one-time site costs for land, construction,
and so forth, and amortizes these costs on an equivalent uniform annual cost basis. This
process leads to the estimates shown in Table 6
