Oregon Revised Statutes Public Financial Administration § 291.244

The Oregon Department of Administrative Services shall act promptly upon all estimates required by ORS 291.242. If the estimate is within the terms of the appropriation as to amount and purposes, having due regard for the probable further needs of the agency for the remainder of the term for which the appropriation was made, and if the department determines that there is a need for the estimated amount for the allotment period, the department shall approve the estimate and allot the estimated amount for expenditures. Otherwise the department shall modify the estimate so as to conform with the terms of the appropriation and the prospective needs of the agency, and shall reduce the amount allotted accordingly.
