(a) Not later than June 1 of each year, the governor shall require the head of each department, office, and agency of the state government to submit to the commissioner of finance and administration a work program for the ensuing fiscal year, such program to include all appropriations made by the general assembly to such department, office, or agency for its operation and maintenance and for capital projects, and to show the requested allotments of the appropriations by quarters for the entire fiscal year. The governor, with the assistance of the commissioner, shall review the requested allotments with respect to the work program of each department, office, or agency, and shall, if the governor deems it necessary, revise, alter, or change such allotments before approving them. The aggregate of such allotments shall not exceed the total appropriations made by the general assembly to the department, office, or agency for the fiscal year in question. The commissioner shall transmit a copy of the allotments as approved by the governor to the head of each department, office, or agency concerned. The commissioner shall thereupon authorize all expenditures to be made from the appropriations on the basis of such allotments and not otherwise.
