RICHMOND, DEC. 28 -- Virginia Gov. L. Douglas Wilder cut an additional $150 million from state spending today, a move that will affect virtually every function of government, from the courts to higher education and social services.

The latest round of cuts, following Wilder's announcement two weeks ago that Virginia's budget gap had grown by $491 million since August, takes 7.5 percent from the budgets of most state agencies. The total revenue shortfall for the two-year budget cycle now stands at $1.9 billion.

Among the largest cuts affecting Northern Virginia are a $2.8 million reduction in state aid to George Mason University and a $6 million statewide cut in the state's share of operating costs for sheriffs, commonwealth's attorneys and other constitutional officers, which will require local governments to contribute more.

The state departments of Health and Social Services -- two agencies that participate jointly with local governments in many programs -- were cut by $5.6 million and $6.4 million respectively. Those cuts raised fears among Northern Virginia officials that services will lag just as the number of people who need the programs is rising rapidly because of the weak economy.

Wilder told members of the General Assembly's money committees on Dec. 17 that a new round of spending reductions -- on top of cuts of 5 percent to 10 percent that already have been made by most agencies -- would be required. But the specifics were not made public until today.

Debate in the General Assembly session starting Jan. 9 will center on whether to accept Wilder's program of deep spending cuts with no new taxes or to look for other solutions.

Wilder has said his cuts have not hurt the delivery of essential government services. As in the previous reductions, the new spending plans today exempted welfare payments from the budget ax.

But others who rely on state government say they are feeling pain.

"It's starting to get pretty ragged and it'll get raggedier," George Mason University President George W. Johnson said of the impact of cuts on his campus.

The latest cuts there will require leaving 103 positions unfilled, a staffing level that is 82 percent of what school officials consider to be ideal. Johnson said the cuts mean some routine maintenance isn't getting done, and such things as research labs and computer software aren't being properly monitored.

Local governments fear the impact of state cuts at a time when the soft economy has created more demand for social services and the slumping real estate market has reduced their property tax revenue.

"In the area of human services, {cuts} are felt more at the local level than anyplace else," said Prince William Supervisor Edwin C. King (D-Dumfries). "It hurts, but we'll survive."

In other spending cuts unveiled today:The State Department of Education is losing more than $1.7 million, requiring the elimination of a program designed to give training to beginning teachers.

The state's community college system was targeted for a $9.1 million cut. In budget documents, the system said it will have to lay off 138 employees and eliminate classes at several campuses unless it is given permission to continue a tuition surcharge ($55.50 per semester for full-time, in-state students) that was implemented earlier this year. Education Secretary James W. Dyke Jr. said he was still studying whether to support tuition surcharges.

The state police are facing an $840,000 cut, which officials plan to meet in part by delaying purchase of new patrol cars.

The Department of Rehabilitative Services said it will trim $1.1 million from a program designed to help learning disabled youngsters.

The State Health Department's $5.6 million cut includes $267,000 that would have gone to hire more health inspectors, and $482,000 for AIDS education and treatment programs.

The Office of the Governor is targeted for almost $160,000 in cuts, which will be made up in part by reducing food and entertainment costs at the Executive Mansion.
