31 USC 1512 - Apportionment and reserves

(a) Except as provided in this subchapter, an appropriation available for obligation for a definite period shall be apportioned to prevent obligation or expenditure at a rate that would indicate a necessity for a deficiency or supplemental appropriation for the period. An appropriation for an indefinite period and authority to make obligations by contract before appropriations shall be apportioned to achieve the most effective and economical use. An apportionment may be reapportioned under this section.
(b) 
(1) An appropriation subject to apportionment is apportioned by
(A) months, calendar quarters, operating seasons, or other time periods;
(B) activities, functions, projects, or objects; or

(2) The official designated in section 1513 of this title to make apportionments shall apportion an appropriation under paragraph (1) of this subsection as the official considers appropriate. Except as specified by the official, an amount apportioned is available for obligation under the terms of the appropriation on a cumulative basis unless reapportioned.
(c) 
(1) In apportioning or reapportioning an appropriation, a reserve may be established only
(A) to provide for contingencies;

Reserves established under this section shall be reported to Congress as provided in the Impoundment Control Act of 1974 (2 U.S.C. 681 et seq.).
(d) An apportionment or a reapportionment shall be reviewed at least 4 times a year by the official designated in section 1513 of this title to make apportionments.

(a) The official having administrative control of an appropriation available to the legislative branch, the judicial branch, the United States International Trade Commission, or the District of Columbia government that is required to be apportioned under section 1512 of this title shall apportion the appropriation in writing. An appropriation shall be apportioned not later than the later of the following:
(1) 30 days before the beginning of the fiscal year for which the appropriation is available; or
(2) 30 days after the date of enactment of the law by which the appropriation is made available.
(b) 
(1) The President shall apportion in writing an appropriation available to an executive agency (except the Commission) that is required to be apportioned under section 1512 of this title. The head of each executive agency to which the appropriation is available shall submit to the President information required for the apportionment in the form and the way and at the time specified by the President. The information shall be submitted not later than the later of the following:
(A) 40 days before the beginning of the fiscal year for which the appropriation is available; or
(B) 15 days after the date of enactment of the law by which the appropriation is made available.

(B) 30 days after the date of enactment of the law by which the appropriation is made available.
(c) By the first day of each fiscal year, the head of each executive department of the United States Government shall apportion among the major organizational units of the department the maximum amount to be expended by each unit during the fiscal year out of each contingent fund appropriated for the entire year for the department. Each amount may be changed during the fiscal year only by written direction of the head of the department. The direction shall state the reasons for the change.

The system shall be designed to
(1) restrict obligations or expenditures from each appropriation to the amount of apportionments or reapportionments of the appropriation; and
(2) enable the official or the head of the executive agency to fix responsibility for an obligation or expenditure exceeding an apportionment or reapportionment.
(b) To have a simplified system for administratively dividing appropriations, the head of each executive agency (except the Commission) shall work toward the objective of financing each operating unit, at the highest practical level, from not more than one administrative division for each appropriation affecting the unit.

31 USC 1515 - Authorized apportionments necessitating deficiency or supplemental appropriations

(a) An appropriation required to be apportioned under section 1512 of this title may be apportioned on a basis that indicates the need for a deficiency or supplemental appropriation to the extent necessary to permit payment of such pay increases as may be granted pursuant to law to civilian officers and employees (including prevailing rate employees whose pay is fixed and adjusted under subchapter IV of chapter 53 of title 5) and to retired and active military personnel.
(b) 
(1) Except as provided in subsection (a) of this section, an official may make, and the head of an executive agency may request, an apportionment under section 1512 of this title that would indicate a necessity for a deficiency or supplemental appropriation only when the official or agency head decides that the action is required because of
(A) a law enacted after submission to Congress of the estimates for an appropriation that requires an expenditure beyond administrative control; or
(B) an emergency involving the safety of human life, the protection of property, or the immediate welfare of individuals when an appropriation that would allow the United States Government to pay, or contribute to, amounts required to be paid to individuals in specific amounts fixed by law or under formulas prescribed by law, is insufficient.
(2) If an official making an apportionment decides that an apportionment would indicate a necessity for a deficiency or supplemental appropriation, the official shall submit immediately a detailed report of the facts to Congress.
