Whenever the Office of Personnel Management finds that the Government’s recruitment or retention efforts with respect to 1 or more occupations in 1 or more areas or locations are, or are likely to become, significantly handicapped due to any of the circumstances described in subsection (b), the Office may establish for the areas or locations involved, with respect to individuals in positions paid under any of the pay systems referred to in subsection (c), higher minimum rates of pay for 1 or more grades or levels, occupational groups, series, classes, or subdivisions thereof, and may make corresponding increases in all rates of the pay range for each such grade or level. However, a minimum rate so established may not exceed the maximum rate of basic pay (excluding any locality-based comparability payment under section 5304 or similar provision of law) for the grade or level by more than 30 percent, and no rate may be established under this section in excess of the rate of basic pay payable for level IV of the Executive Schedule. In the case of individuals not subject to the provisions of this title governing appointment in the competitive service, the President may designate another agency to authorize special rates under this section.

The head of an agency may determine that a category of employees of the agency will not be covered by a special rate authorization established under this section. The head of an agency shall provide written notice to the Office of Personnel Management (or other agency designated by the President to authorize special rates under the last sentence of paragraph (1)) which identifies the specific category or categories of employees that will not be covered by special rates authorized under this section. If the head of an agency removes a category of employees from coverage under a special rate authorization after that authorization takes effect, the loss of coverage will take effect on the first day of the first pay period after the date of the notice.

rates of pay offered by non-Federal employers being significantly higher than those payable by the Government within the area, location, occupational group, or other class of positions under the pay system involved;

the remoteness of the area or location involved;

the undesirability of the working conditions or the nature of the work involved (including exposure to toxic substances or other occupational hazards); or

any other circumstances which the Office of Personnel Management (or such other agency as the President may under the last sentence of subsection (a)(1) designate) considers appropriate.

a statutory pay system; or

any other pay system established by or under Federal statute for civilian positions within the executive branch.

The benefit of any comparability payments under section 5304 shall be available to individuals receiving rates of pay established under this section to such extent as the Office of Personnel Management (or such other agency as the President may under the last sentence of subsection (a)(1) designate) considers appropriate, subject to paragraph (2) and subsection (h).

Payments under this subsection may not be made if, or to the extent that, when added to basic pay otherwise payable, such payments would cause the total to exceed the rate of basic pay payable for level IV of the Executive Schedule.

First, determine the rate of pay to which such employee would be entitled at the new official duty station based on such employee’s position, grade, and step (or relative position in the rate range) before the move.

Then, if (in addition to the change in pay schedule) the move also involves any personnel action or other change requiring a rate adjustment under any other provision of law, rule, or regulation, apply the applicable rate adjustment provisions, treating the rate determined under paragraph (1) as if it were the rate last received by the employee before the rate adjustment.
