A Washington limousine company has been refused the right to enter into contracts to provide shuttle van service for two U.S. government agencies because a regulatory agency found it "impossible to make the affirmative finding of the company's fitness to do the job."

In turning down an application by International Limousine Service Inc., the Washington Metropolitan Area Transit Commission said the firm had a record of conducting operations without legal authority, failing to abide by the level of fares set by the commission and ignoring commission warnings on at least two occasions.

International applied last month for a certificate permitting it to run shuttle service for the Energy Department and the Interior Department's Bureau of Mines, carrying employes and agency mail among their offices. According to the transit commissioner, the firm submitted lower bids for the contract than those of the present operator, Beltway Limousine Service.

Beltway protested, and submitted figures contending that International would lose money on the contracts, requiring it to make up losses by overcharging other customers. To buttress its case, Beltway cited two instances of alleged overcharges by International -- $145 for a chartered trip that should have cost $75.90 under International's tariff and $202 for a sightseeing tour that should have cost $114. The Transit Commission, in its order, agreed with Beltway.

The commission also scheduled a formal hearing Jan. 11 into International's conduct of its business.

J.W. Glover, lawyer for Remi Fogliarino, International's president, said the prices charged for the two disputed trips were identical to those quoted when the charters were arranged. Glover, saying he was newly retained, offered no comment on the commission decision.

Elsie Munsell, who has served as federal magistrate for two years in Alexandria, was sworn in yesterday as U.S. attorney for the eastern judicial district of Virginia. She is the first woman to hold the job.

Munsell, 42, will be responsible for federal prosecutions at courts in Alexandria, Richmond, Norfolk and Newport News. She was appointed by President Reagan from a list of five candidates submitted by Sen. John W. Warner (R-Va.), who attended the swearing-in ceremony. She replaced Justin Williams, the U.S. attorney since 1979.

If you're looking for an important Maryland politician today, you'll likely find him in Rockville. At 1 p.m., Montgomery County will dedicate its new courthouse and government office complex, and everyone who is anyone in state affairs is expected to attend -- Gov. Harry Hughes, the two U.S. senators, Montgomery's congressman and the chief judge of the state's highest court, Robert E. Murphy.

The twin-towered $33 million complex occupies a five-acre site near Rockville Mall and houses 1,575 employes.

There's bad news for turkeys in Maryland this Thanksgiving, which means there's good news for turkey growers. The state's seven large turkey farms will sell about 100,000 of the birds this year, up from 86,000 last year, according to an estimate by the state Department of Agriculture.

Most Maryland turkeys are sold unfrozen, a condition that commands a premium price -- from $1.10 to $1.20 a pound compared with 52 cents to 89 cents frozen. Evelyn Schramm, who has helped run her family's farm at Pasadena in Anne Arundel County for 35 years, said one Washington man picked up seven turkeys on Sunday.

The Fairfax County Board of Supervisors has put the issue of the Springfield Bypass route on the back burner until after Charles S. Robb takes office as governor in January.

Outgoing Gov. John N. Dalton has agreed with the State Highway Commission that a route proposed by the Virginia Department of Highways and Transportation should be chosen for the proposed cross-county artery. It differs from the county's proposed alignent, mainly on the sections that would intersect with I-95 and I-66. Robb, a Fairfax County resident, has sided with the county position.

On Monday night, the county board voted unanimously to postpone further discussion on the issue until February. Within 90 days, the board must decide whether to amend the county master plan by changing the road's proposed route.
