The D.C. Federation of Civic Associations and the D.C. League of Women Voters will sponsor a debate Aug. 13 for candidates to at-large D.C. Council seats and contenders for council chairman and mayoral candidates.

The forum will be held at the District Building in the Council Chambers beginnning at 6:45 p.m., according to Ronnie L. Edwards, an organizer of the event.

Edwards said the format will be the same for each set of candidates: a two-minute opening statement followed by a round of questions from representatives of the sponsoring organizations. Questions from the floor will be permitted before each candidate offers closing remarks.

In addition, the Fort Lincoln Civic Association will hold a series of candidate forums at the Fort Lincoln Community School gymnasium. A spokesman for the association said the forums will range from Ward 5 issues to citywide problems.

The dates and schedules for the meetings are: July 23, D.C. delegate to Congress and mayoral candidates; Aug. 6: D.C. Council chairman and council candidates, and Aug. 20, Ward 5 council candidates.

A uniform uniform is in the works for Metro subway and bus employes.

In more than 10 years since train service began -- supplementing the bus service that previously was acquired from four private companies -- bus drivers and other uniformed employes of the bus division have worn blue uniforms while train operators and station employes have worn tan. (One who knew him suspects with good reason that the late Maj. Gen. Jackson Graham, Metro's first general manager and an old Army man, was partial to his service's more drab monochromatic look.)

Last month, with the Army influence declining, the Metro board voted to adopt blue as the color for all uniformed employes. A contract was awarded to the Gale-Sobel Co. of St. Louis. The change will take place April 1.

"This contract culminates almost two years of efforts by the transit authority's employes to design a uniform that meets the requirements of management and the needs of our employes," said General Manager Carmen Turner.

The only difference between the two groups of employes will be a bus or rail patch worn on the sleeve of the jacket or shirt, much as military personnel wear insignia of their units.

Under Metro's union contract with its employes, the latter pay the cost of their own uniforms. Metro estimated that it will cost $331 for four pairs of trousers, 10 shirts, a tie and a sweater -- about the same as the old uniforms cost four years ago, but for better quality.

There will be one lingering group of tan-uniformed employes: the Metro police.

Transit Official Honored

Speaking of the Metro police, the announcement that its chief has received the transit authority's highest annual honor got lost in the shuffle during the July 4 weekend.

The award is the Jackson Graham Memorial Award, named for the previously mentioned official and given annually to recognize the highest standards of leadership, integrity, fairness and dedication to duty. Angus McLean, a former military police colonel who was chosen by Graham to head the Metro force when it was being formed in 1972, was the recipient.

A native of Lorain, Ohio, and a University of Maryland graduate, McLean lives in Burke.

Another top Metro prize, the General Manager's Award, went to Paul C. Gillum Jr., Metrobus director of quality assurance trainiing. He lives in Stafford.
