Title 5 - Administrative Personnel
(a) The Secretary may establish local market supplements that apply in specified local market areas whose boundaries are set at the Secretary's sole and exclusive discretion, subject to paragraph (b) of this section and §9901.105(d)(4). Local market supplements apply to employees whose official duty station is located in the given local market area. The Secretary may establish standard or targeted local market supplements.

As provided by the non-waived provisions of 5 U.S.C. 5304(f)(2) (modified here to apply to DoD regulations issued under the authority of this paragraph), judicial review of any such regulation is limited to whether or not it was promulgated in accordance with such requirements. (2) Notwithstanding paragraph (b)(1) of this section, the Secretary's establishment of a standard local market area boundary or boundaries identical to those used for locality pay areas established under 5 U.S.C. 5304 does not require separate DoD regulations.
