16 U.S. Code § 5955 - Reasonableness of rates
(a) In general
Each concessions contract shall permit the concessioner to set reasonable and appropriate rates and charges for facilities, goods, and services provided to the public, subject to approval under subsection (b) of this section.
(b) Approval by Secretary required
A concessioner’s rates and charges to the public shall be subject to approval by the Secretary. The approval process utilized by the Secretary shall be as prompt and as unburdensome to the concessioner as possible and shall rely on market forces to establish reasonableness of rates and charges to the maximum extent practicable. The Secretary shall approve rates and charges that the Secretary determines to be reasonable and appropriate. Unless otherwise provided in the contract, the reasonableness and appropriateness of rates and charges shall be determined primarily by comparison with those rates and charges for facilities, goods, and services of comparable character under similar conditions, with due consideration to the following factors and other factors deemed relevant by the Secretary: length of season, peakloads, average percentage of occupancy, accessibility, availability and costs of labor and materials, and type of patronage. Such rates and charges may not exceed the market rates and charges for comparable facilities, goods, and services, after taking into account the factors referred to in the preceding sentence.
(c) Implementation of recommendations
Not later than 6 months after receiving recommendations from the Advisory Board established under section 5958 (a) of this title regarding concessioner rates and charges to the public, the Secretary shall implement the recommendations or report to the Congress the reasons for not implementing the recommendations.
