Top Prince George's County officials said yesterday they were shocked to learn of a Schaefer administration proposal to build a minimum-security prison in Prince George's County, which would be the first state penal facility in the Washington suburbs.

The proposal, reported yesterday in the Baltimore Sun, detailed Gov. William Donald Schaefer's $330 million, 11-year plan to raze the Maryland Penitentiary in Baltimore and build additional prison facilities that would include a 192-bed pre-release center in Prince George's.

State corrections officials will unveil the entire prison proposal Wednesday in Annapolis. Under the plan, which would be subject to legislative approval, the Prince George's facility would be built in three to six years along with a 720-bed medium-security facility to be opened by 1999, possibly in Allegany County.

While Maryland Senate President Thomas V. Mike Miller Jr. (D-Prince George's) and other county senators said they were not consulted about the plan, a high-level administration official said some county officials were informed that a proposal was going to be announced and that Prince George's might be affected.

Several Prince George's legislators, clearly angry to learn about the proposal through news reports, said Schaefer's failure to brief delegation members in advance may make it more difficult for the county to accept such a facility and some doubted that the plan will move forward.

"It comes as a complete surprise to me," said Sen. Frank J. Komenda (D-Prince George's), who sits on the Joint Executive Legislative Committee on Long Range Planning for Corrections and chairs the Senate's budget oversight committee for the Department of Correction. "I think the whole plan, whether we are talking about the Prince George's ingredient or all of it, is going to have to undergo intense scrutiny."

"At first blush, I'm violently opposed to it," said Sen. Arthur Dorman (D-Prince George's). "The governor should have made contact with the elected officials in {the county}. I don't think anybody in Prince George's County is waving a flag for it."

County Executive Parris Glendening's spokesman Tim Ayers said county officials also were surprised to read about the proposal. County legislative lobbyist Royal Hart said his office was contacted Thursday by the governor's staff and told that Schaefer would unveil his master plan for the prison system in the next few days and would arrange for a briefing of county and state officials. Hart said he was told Prince George's would be "impacted" in about the third or fourth year of the program.

Miller said he heard about the plan, including the Prince George's component, from reporters who called him Thursday for comment. But Miller said he doubted the proposal is a final draft and speculated that it might be a preliminary one "drafted by some low-level bureaucrat" who leaked it to the press.

"There has been no announcement from {Shaefer's} office regarding any plan," Miller said. "It is . . . a comprehensive package that involves several jurisdictions and includes the demolition of a major facility.

"Since the governor has come into office, we have collectively been trying to help him help Baltimore City," Miller said. "But you don't help Baltimore City by affecting other jurisdictions. This does not seem a polite way to reciprocate for that help."

The Prince George's Senate delegation plans to meet with Schaefer Tuesday in a previously scheduled meeting and will raise the prison plan then.

Prince George's County and state officials, while agreeing that all counties must share the burden of the state prison system, appeared divided over the wisdom of putting a facility in one of the most populous counties in the state.

"It is totally inconsistent with the quality of life in Prince George's," said Miller, who represents the rural southern section of the county, which some legislators suggested would be the most likely site of a prison facility. "We do have areas in the state that have them and are seeking additional prisons for economic development. We don't have that situation in Prince George's."

But Del. Timothy F. Maloney (D-Prince George's), who chairs the House Appropriations subcommittee that oversees the Correction Department budget, said the county sends the second highest number of inmates to the prison system, behind Baltimore.

"We need a transitional facility to make sure Prince George's prisoners coming back into the county are drug-free, have vocational skills and reading and writing skills," he said. "There will be a state prerelease center in Prince George's, but the question is when and where. No facility will be built until there is a political consensus on where."
