Prince George's County officials are preparing for the worst but expecting nothing to happen when the clocks roll over to announce a new century on Jan. 1.

Officials are advising residents to go to the nearest fire station if disaster strikes on New Year's Day. Among the potential scenarios: loss of power, telephone service or any number of worst-case possibilities that have been played out on the Internet, in the media and in a recent made-for-TV thriller about a catastrophic Y2K computer disaster.

Prince George's County Council member Audrey E. Scott (R-Bowie) said she has advised her constituents to have on hand plenty of batteries and a couple of days' worth of food--just in case. But she said she will be surprised if there are problems associated with the turn of the century.

"I don't anticipate airplanes will be falling out of the sky," she said. "I've had people from the community ask me about the automatic locks at the jail. We've tested all of them. I don't see suddenly all the jail doors are going to open up and all the prisoners are going to be wandering the streets."

The county has established a hot line for residents to call if they have questions or worries. The number is 301-Y2K-1999. The hot line is staffed with 15 to 18 county employees who have been specially trained to answer questions.

Libby Clapp, the county's information technology director, said that if the lines get flooded, more phones and operators will be added. But she said it's hard to predict how busy the hot line will be.

"Who's got the crystal ball on this one?" she said.

In the days leading up to New Year's Eve, county workers are backing up all computer systems and taking the data to the Largo government center on Landover Road, where it could be made available if there is a major power outage or other equipment failure. The information will be stored on stand-alone computers not linked to a network that could be affected by other problems.

At some point before Dec. 31--Clapp declined to say when for security reasons--the county will check for computer viruses on incoming e-mail. The system also will be rigged so that no files can be downloaded from the Internet--another precaution against viruses.

On New Year's Eve, County Executive Wayne K. Curry (D), all department directors and emergency preparedness and public safety officials will be at a command center in the county's 911 emergency dispatch center. The center is equipped with telephone and computer data lines.

A staff of 20 to 30 computer system specialists also will be on hand at the Largo government center, which houses the fire department's administrative offices.

The Largo government center was built with a special generator that has a 31-day supply of fuel. Special orange-coded electrical outlets in the building are connected to that generator.

"Our backup is that we keep doing business as usual," Clapp said. "The whole building can run on its own. We'd just deploy people there."

Clapp said county officials will start monitoring the Internet and reports from federal agencies at 8 a.m. on New Year's Eve, when officials in Australia get the first peek at the new year.

As an added precaution, there is limited time off for all county public safety personnel, which includes 1,385 police officers, 655 professional firefighters and medical technicians and 350 corrections officers.

The school system will dispatch workers at 6 a.m. Jan. 1 to make certain that everything is working in time for the schools to reopen Jan. 3.

"If something happens, we will just close the schools down and add another date to the end of the year," said school board Chairman James E. Henderson (Seabrook). But he isn't worried that there will be problems.

The county has spent about $23 million to replace and upgrade computer systems and parts that would not have worked in 2000.

That figure is small compared with other area jurisdictions. Montgomery County spent $50 million on Y2K preparations.

Even so, some County Council members criticized the amount spent on Y2K computer fixes.

"It seems to me too much money has been spent on it," said council member Isaac J. Gourdine (D-Fort Washington). "To be frank, I don't see the problem. A lot of the problems that people have are in their minds."

Council member Walter H. Maloney (D-Beltsville) said he is more concerned about what he calls the county's "Y1999 problem."

Maloney said the Y2K bug has been an excuse for the county to spend money. "We got new hardware, a color scanner," he said of his own office. "I could have gotten two or three other gadgets if I had asked. Maybe I could get my office painted."

Clapp, the county's information technology director, said her biggest worry is that people will overreact because of something unrelated to Y2K.

She said a snow or ice storm could cut power, a normal winter occurrence that wouldn't necessarily cause a panic. But a power outage near New Year's Eve could be blamed on Y2K glitches.

She noted that the county underwent an unplanned test of traffic signals during Hurricane Floyd when parts of the county were without power for four to five days in September.

She said traffic signals already are equipped with backup systems and are programmed to blink red or yellow in case the power fails.

One of the systems that had to be replaced was the computer that controlled the scales at the landfill. The component that logged the license and registration of a dump truck was not Y2K-compatible and would have rejected the vehicle after Dec. 31, believing its license or registration to be expired.

Council member Ronald V. Russell (D-Mitchellville) said the county has no choice but to take Y2K seriously.

"Hopefully we're going to be as prepared as any jurisdiction," he said.

"Is this a marketing scheme? I don't think so."

Just in Case: A Checklist of Y2K Helpful Hints and Phone Numbers

If the new year brings problems to Prince George's County, here is a list of places to go and phone numbers to call. In the case of a power outage, you should have extra batteries, a water supply (at least one gallon per person per day), at least three days' worth of canned goods and enough cash for a few days. Also make sure that your gas tank is more than half full and that computers, security systems, thermostats and other home equipment are Y2K-compatible.
