§ 591.232 How does OPM establish and review post differentials?

5 CFR 591.232(a)(a) OPM establishes a post differential by rulemaking if Government agencies require it for recruitment purposes and if one or more of the following conditions exist:

5 CFR 591.232(a)(1)(1) Extraordinarily difficult living conditions,

5 CFR 591.232(a)(2)(2) Excessive physical hardship, and/or

5 CFR 591.232(a)(3)(3) Notably unhealthful conditions.

5 CFR 591.232(b)(b) OPM periodically reviews with Federal agencies whether conditions of environment have changed in the post differential areas and whether payment of the post differential continues to be warranted as a recruitment incentive.
