The information we received from Hanford ops indicated that hauling would not occur on day shift or swing shift today, 12/19.  The 1-3Hz seismic trace during the day today looks pretty noisy, however, as if hauling is occurring.  I'll pursue this next week -- perhaps there's other activity underway nearby.  No hauling is scheduled for the weekend.  Next week the drivers are scheduled to work day and swing on Monday and Tuesday and then go out for the remainder of the week and the weekend.  I suspect that they'll use a similar schedule during the week of Jan 1.
