2. (b)The contractor responsible for a new Hazard Category 1, 2, or 3 DOE nuclear facility must submit for DOE approval a procedure for its USQ process on a schedule that allows DOE approval in a safety evaluation report issued pursuant to § 830. 207(a) of this part.
3. (c)The contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must implement the DOE-approved USQ procedure in situations where there is a:

   1. (1)Take action, as appropriate, to place or maintain the facility in a safe condition until an evaluation of the safety of the situation is completed;
   2. (2)Notify DOE of the situation;
   3. (3)Perform a USQ determination and notify DOE promptly of the results; and
   4. (4)Submit the evaluation of the safety of the situation to DOE prior to removing any operational restrictions initiated to meet paragraph (f)(1) of this section.
