Prince George's County Council members met yesterday to approve budgets for two bicounty agencies, but spent most of their time hurling unusually acrimonious remarks at each other.

One discussion, led by Anthony Cicoria, took place over whether employes of the Washington Suburban Sanitary Commission should be assigned cars to take home.

WSSC officals argued that the 33 employes who enjoy such a privilege need them to respond to emergency calls after hours. Eliminating the program might save no more than $10,000, council aides said, but Cicoria was not dissuaded.

"If an employe is spending so much time in the car, why does he need an office?" Cicoria demanded. Cicoria asked the council to delete any funds for the take-home cars, but other council members said the county would wind up paying the employes more money in mileage.

The council finally voted 6 to 1 to ask the WSSC to find its own way to cut down the number of cars assigned, and approved a $388 million budget that would eliminate cost-of-living raises for 2,000 agency employes.

County officials, in the face of a projected $30 million deficit, had already decided not to grant any raises to Prince George's county employes this year.

The fiscal 1984 budget approved yesterday represents an increase of approximately 5 percent over last year's WSSC budget. That budget would mean the average homeowner who uses 100,000 gallons of water a year would face a tax bill of about $268, or $14 higher than this year's.

Prince George's proposal must be reconciled with that of Montgomery County, which has proposed a 12 percent budget increase.

The council's proposed $31.8 million budget for the Maryland-National Capital Park and Planning Commission set up a shouting match between council members William Amonett and Floyd Wilson, who objected to Amonett's move to get money for a $300,000 community center in his district.

"Where you going to get the money for these projects? You just going to say eeny-meeny-miny-mo?" Wilson yelled at Amonett, who turned a bright red.

Money for the center was approved 6 to 0, with Wilson abstaining. Wilson and Amonett could be heard arguing after the meeting was adjourned.
