(a) Enforcement
(1) Sequestration Within 15 calendar days after Congress adjourns to end a session and on the same day as a sequestration (if any) under section
902 of this title and section
903 of this title, there shall be a sequestration to eliminate a budget-year breach, if any, within any category.
(2) Eliminating a breach Each non-exempt account within a category shall be reduced by a dollar amount calculated by multiplying the baseline level of sequestrable budgetary resources in that account at that time by the uniform percentage necessary to eliminate a breach within that category; except that the health programs set forth in section
906 (e) of this title shall not be reduced by more than 2 percent and the uniform percent applicable to all other programs under this paragraph shall be increased (if necessary) to a level sufficient to eliminate that breach. If, within a category, the discretionary spending limits for both new budget authority and outlays are breached, the uniform percentage shall be calculated by
(A) first, calculating the uniform percentage necessary to eliminate the breach in new budget authority, and
(B) second, if any breach in outlays remains, increasing the uniform percentage to a level sufficient to eliminate that breach.
(3) Military personnel If the President uses the authority to exempt any military personnel from sequestration under section
905 (f) of this title, each account within subfunctional category 051 (other than those military personnel accounts for which the authority provided under section
905 (f) of this title has been exercised) shall be further reduced by a dollar amount calculated by multiplying the enacted level of non-exempt budgetary resources in that account at that time by the uniform percentage necessary to offset the total dollar amount by which outlays are not reduced in military personnel accounts by reason of the use of such authority.
(4) Part-year appropriations If, on the date specified in paragraph (1), there is in effect an Act making or continuing appropriations for part of a fiscal year for any budget account, then the dollar sequestration calculated for that account under paragraphs (2) and (3) shall be subtracted from
(A) the annualized amount otherwise available by law in that account under that or a subsequent part-year appropriation; and
(B) when a full-year appropriation for that account is enacted, from the amount otherwise provided by the full-year appropriation.
(5) Look-back
If, after June 30, an appropriation for the fiscal year in progress is enacted that causes a breach within a category for that year (after taking into account any sequestration of amounts within that category), the discretionary spending limits for that category for the next fiscal year shall be reduced by the amount or amounts of that breach.
(6) Within-session sequestration
If an appropriation for a fiscal year in progress is enacted (after Congress adjourns to end the session for that budget year and before July 1 of that fiscal year) that causes a breach within a category for that year (after taking into account any prior sequestration of amounts within that category), 15 days later there shall be a sequestration to eliminate that breach within that category following the procedures set forth in paragraphs (2) through (4).
(7) Estimates
(A) CBO estimates
As soon as practicable after Congress completes action on any discretionary appropriation, CBO, after consultation with the Committees on the Budget of the House of Representatives and the Senate, shall provide OMB with an estimate of the amount of discretionary new budget authority and outlays for the current year (if any) and the budget year provided by that legislation.
(B) OMB estimates and explanation of differences
Not later than 7 calendar days (excluding Saturdays, Sundays, and legal holidays) after the date of enactment of any discretionary appropriation, OMB shall transmit a report to the House of Representatives and to the Senate containing the CBO estimate of that legislation, an OMB estimate of the amount of discretionary new budget authority and outlays for the current year (if any) and the budget year provided by that legislation, and an explanation of any difference between the 2 estimates. If during the preparation of the report OMB determines that there is a significant difference between OMB and CBO, OMB shall consult with the Committees on the Budget of the House of Representatives and the Senate regarding that difference and that consultation shall include, to extent practicable, written communication to those committees that affords such committees the opportunity to comment before the issuance of the report.
(C) Assumptions and guidelines
OMB estimates under this paragraph shall be made using current economic and technical assumptions. OMB shall use the OMB estimates transmitted to the Congress under this paragraph. OMB and CBO shall prepare estimates under this paragraph in conformance with scorekeeping guidelines determined after consultation among the House and Senate Committees on the Budget, CBO, and OMB.
(D) Annual appropriations
For purposes of this paragraph, amounts provided by annual appropriations shall include any new budget authority and outlays for the current year (if any) and the budget year in accounts for which funding is provided in that legislation that result from previously enacted legislation.
