MONTPELIER (AP) - Budget writers in the Vermont House are getting to work more than a month ahead of the official legislative session to prepare a mid-year budget adjustment bill.

The House Appropriations Committee is due to meet Monday to begin deliberations on an estimated $13.5 million in upward changes on a budget passed spring that totaled more than $5 billion.

It's an annual process in which lawmakers are asked to respond to unforeseen needs in the middle of the fiscal year.

Finance and Management Commissioner Jim Reardon told lawmakers at a preliminary briefing earlier this month that some of the upward pressures are in the Corrections and Mental Health departments.
