7. If equipment is in standby mode due solely to a documented NPS delay, established standby rate shall apply from the first day of the delay.

8. Equipment not used and on job site for up to five consecutive days may be classified at standby rates, provided the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work.
