Expect the usual day shift and swing shift 1-3 Hz noise on Friday.  No weekend Hanford transportation activity is scheduled.  It's possible that Hanford hauling through the Wye barricade could decrease by 30-40% after March and make another significant decrease in July as excavation operations in the 300 area wind down.  Hauling from the 618-10 remediation area on Stevens will continue.  The uncertainty associated with these forecasts is large, however.
