Lawmakers have been anticipating the curtailment order for several weeks, since lower state revenues were forecast in November.

The Portland Press Herald reported that the announcement could come as early as Wednesday.

The administration also is preparing a supplemental budget to close a projected shortfall in the two-year budget that ends June 30. That gap is because of a projected $100 million shortfall in Health and Human Services.

Michael Allen, the state’s associate commissioner of tax policy, told lawmakers in November that the revenue shortfall comes from a convergence of events including the “fiscal cliff” negotiations in Congress and a Maine economy that is not growing as quickly as hoped.
