Section 591.304 - Criteria for determining remoteness(a) Except as provided by paragraphs (b) and (c) of this section, a duty post shall be determined to be a remote duty post for basic allowance eligibility purposes when:(1) Normal ground transportation (e.g., automobile, train, bus) is available on a daily basis and the duty post is 80 kilometers (50 miles), or more, one way from the nearest established community or suitable place of residence. Distance shall be computed in road or rail kilometers (miles) over the most direct route traveled from the center of the city, or other appropriate point for large cities or areas; or(2) Daily commuting is impractical because the location of the duty post and available transportation are such that agency management requires employees to remain at the duty post for their workweek as a normal and continuing part of the conditions of employment; or(3) Transportation may be accomplished only by boat, aircraft, or unusual conveyance, or under extraordinary conditions, and the distance, time, and commuting conditions result in expense, inconvenience, or hardship significantly greater than that encountered in metropolitan area commuting. A determination may only be made on an individual location basis.(b) Except when the criteria in paragraph (a)(2) or (3) of this section are met, the criteria in paragraph (a)(1) of this section are not met: (1) When the duty post is within the boundary of a metropolitan area, a developed urban area, or community of sufficient size to provide adequate consumer facilities; and(2) When the duty post is within 80 kilometers (50 miles) of the center of, or other appropriate point for large cities or areas, a metropolitan area, a developed urban area, or community of sufficient size to provide adequate consumer facilities. (This generally excludes a post of duty within 80 kilometers (50 miles) of any city of 5,000 or more population.)(c) A determination of remoteness for a duty post outside the 50 United States will be made on an individual location basis, taking into consideration the distance, time, and commuting conditions, and the extent to which these factors result in significant expense, inconvenience, or hardship.44 FR 55134, Sept. 25, 1979, as amended at 58 FR 32278, June 9, 1993
