(c) In computing a lump-sum payment for accumulated annual leave under 5 U.S.C. 5551 and 5552 for firefighters with an uncommon tour of duty established under § 630.210 of this chapter for leave purposes, an agency must use the rates of pay for the position held by the firefighter that apply to hours in that uncommon tour of duty, including regular overtime pay for such hours.

(d) A firefighter compensated under this subpart shall receive basic pay and overtime pay for his or her regular tour of duty in any week in which attendance at agency-sanctioned training reduces the hours in the firefighter's regular tour of duty, as provided in § 410.402(b)(6) of this chapter.
