State management: funds; work project appropriations; require legislative approval for, and prohibit the expenditure of the funds under certain circumstances. Amends sec. 451a of 1984 PA 431 (MCL 18.1451a).

HB 4800 amends Michigan's budget law to regulate how state funds for specific projects ("work projects") are managed. It requires that new work projects must have a clear purpose, detailed plan, estimated cost, and completion date, and must be approved by budget committees within 30 days. The bill sets a 24-month limit for project funds to remain available (after which unused funds return to the state), mandates quarterly reports from the budget director to lawmakers on project balances and lapses, and allows committees to halt spending if funds are misused or not used timely. This directly affects state agencies receiving project funds and budget committees overseeing fiscal accountability.
