No, it's not hearsay.
A considerable amount of effort was undertaken by agency staff in visiting with the railways at the main shops where the activity was undertaken. Part of the problem, which was discussed in the earlier proceedings, was that the railways do not collect detailed information with respect to the maintenance of the hopper cars, which made the assignment or study more difficult to undertake. The $1,800 determination was the best figure that could be determined under the circumstances.
Whether a better estimate can be undertaken remains to be seen, and it's something we will be looking at very closely in the next month or so.
