5 CFR 531.609 - Adjusting or terminating locality rates.
(a) When an employee's official worksite is changed to a different locality pay area, the employee's entitlement to the locality rate for the new locality pay area begins on the effective date of the change in official worksite.
(2) An employee is no longer in a position covered by this subpart; or
(3) An employee separates from Federal service.
(d) In the event of a change in the geographic coverage of a locality pay area, the effective date of any change in an employee's entitlement to a locality rate of pay under this subpart is the first day of the first pay period beginning on or after the effective date indicated in the applicable final rule published in the Federal Register.
