§924 Withdrawal or Limitation of Assignment to Federal Government Stations

Title 47 › CHAPTER 8 — NATIONAL TELECOMMUNICATIONS AND INFORMATION ADMINISTRATION › SUBCHAPTER II — TRANSFER OF AUCTIONABLE FREQUENCIES › § 924

Last updated Sep 22, 2026|Official source

Summary

The President must remove or limit a radio frequency’s use by Federal Government stations when the Secretary’s report calls for immediate reallocation or immediate mixed use. The President has 6 months from getting that report to act. If the Secretary sets a later effective date, the President must remove or limit the Federal use on that delayed date (unless an exception applies). The President may also assign different frequencies to Federal stations to make the change work. The President must send a notice and description of what was done to the Commission and to each House of Congress. If the President finds a serious problem, he may substitute a different frequency instead of the one named in the report. He must then explain the reasons to the Commission, the Committee on Energy and Commerce of the House of Representatives, and the Committee on Commerce, Science, and Transportation of the Senate. Reasons include threats to national defense, unique government needs, serious risks to health or safety, excessive government costs, or harm to amateur radio use. Any substitute frequency must meet the same criteria the Secretary used. If the action cannot be finished by the delayed date or would leave a frequency unused under the Commission’s plan, the President may delay the change (with notice) or substitute other frequencies.

(a)In general
The President shall—
(1)within 6 months after receipt of a report by the Secretary under subsection (a), (d)(1), or (f) of section 923 of this title, withdraw the assignment to a Federal Government station of any frequency which the report recommends for immediate reallocation;
(2)within any such 6-month period, limit the assignment to a Federal Government station of any frequency which the report recommends be made immediately available for mixed use under section 923(b)(2) of this title;
(3)by the delayed effective date recommended by the Secretary under section 923(e) of this title (except as provided in subsection (b)(4) of this section), withdraw or limit the assignment to a Federal Government station of any frequency which the report recommends be reallocated or made available for mixed use on such delayed effective date;
(4)assign or reassign other frequencies to Federal Government stations as necessary to adjust to such withdrawal or limitation of assignments; and
(5)transmit a notice and description to the Commission and each House of Congress of the actions taken under this subsection.
(b)Exceptions
(1)Authority to substitute
If the President determines that a circumstance described in paragraph (2) exists, the President—
(A)may substitute an alternative frequency or frequencies for the frequency that is subject to such determination and withdraw (or limit) the assignment of that alternative frequency in the manner required by subsection (a); and
(B)shall submit a statement of the reasons for taking the action described in subparagraph (A) to the Commission, Committee on Energy and Commerce of the House of Representatives, and the Committee on Commerce, Science, and Transportation of the Senate.
(2)Grounds for substitution
For purposes of paragraph (1), the following circumstances are described in this paragraph: (A)
(B)the frequency proposed for reassignment is uniquely suited to meeting important governmental needs;
(C)the reassignment would seriously jeopardize public health or safety;
(D)the reassignment will result in costs to the Federal Government that are excessive in relation to the benefits that may be obtained from commercial or other non-Federal uses of the reassigned frequency; or
(E)the reassignment will disrupt the existing use of a Federal Government band of frequencies by amateur radio licensees.
(3)Criteria for substituted frequencies
For purposes of paragraph (1), a frequency may not be substituted for a frequency identified and recommended by the report of the Secretary under section 923(a) of this title unless the substituted frequency also meets each of the criteria specified by section 923(a) of this title.
(4)Delays in implementation
If the President determines that any action cannot be completed by the delayed effective date recommended by the Secretary pursuant to section 923(e) of this title, or that such an action by such date would result in a frequency being unused as a consequence of the Commission’s plan under section 925 of this title, the President may—
(A)withdraw or limit the assignment to Federal Government stations on a later date that is consistent with such plan, except that the President shall notify each committee specified in paragraph (1)(B) and the Commission of the reason that withdrawal or limitation at a later date is required; or
(B)substitute alternative frequencies pursuant to the provisions of this subsection.
