An incorrect date was listed in yesterday's District Weekly for the public hearing on Metro fare increases being held April 9 at the Washington Metropolitan Area Transit Authority board room, 600 5th St. NW at 7:30 p.m. The hearing is one of several being held throughout the Washington area.

For the first time in three years, increases in both bus and subway fares appear likely for D.C. residents, effective June 29.

The Metro Board next Wednesday will begin a series of public hearings on proposals to raise fares. Metro is projecting a record $276 million operating budget for the fiscal year beginning July 1, and the expectation is that, without a fare increase, the District of Columbia subsidy of Metro could top $76 million.

Fare increases could cut that requirement for the financially pressed District government by $6 million to $10 million. Mayor Marion Barry has said he supports fare increases, although there is still opposition in the City Council. While the Metro Board technically sets fares, it does so with the approval and concurrence of the local government involved.

Two hearings are scheduled in the District; both begin at 7:30 p.m.:

Wednesday, March 26 -- Mary Church Terrell Elementary School, Wheeler Road and Savannah Street SE.

Wednesday, April 19 -- Washington Metropolitan Area Transit Authority board room, 600 5th St. NW.

The District of Columbia would continue its policy of reducing all rush-hour fares by 10 cents for all riders entering or leaving the subway at the Minnesota Avenue or Deanwood stations. Passengers using the Benning Road station, on the Blue Line segement scheduled for operation late this year, would also receive the 10-cent discount. The discount does not apply to the 50-cent "off-peak" fare. Bus Fares

The District is proposing a bus fare increase and new or increased surcharges on express routes.

Under the Barry administration proposal, the rush-hour D.C. bus fare would increase from 50 cents to 55 cents.

The 40-cent nonrush -- hour D.C. bus fare would increase to 50 cents, thus ending the 10-year-old 40-cent fare.

Premium fares would be charged on some express routes. The L-1 Capitol Hill express fare would be $1; the P-9 express from the South Capitol Street fringe parking lot would cost 75 cents, as would the B-9 express from the Carter Barron fringe parking lot.

Bus fare for the elderly and handicapped, for trips within the District of Columbia, will remain 20 cents at all times, except on the surcharged express routes, where the surcharges would have to paid.

School tokens will continue to be available, in lots of 10 for $1 or 20 for $2. Subway Fares

Two proposed subway fare schedules are up for discussion. One would raise rush-hour fares by about 11 percent for all trips; the other would raise rush-hour fares approximately 22 percent for all trips. Rush-hour fares are charged weekdays between 6 a.m. to 9:30 a.m. and between 3 p.m. and 6:30 p.m. Under the 11-percent solution, the basic rush-hour fare would increase from 45 cents to 50 cents for a three-mile trip. An additional 10.5 cents would be charged for each additional mile. The fair from Brookland to Farragut North would increase from 55 cents to 60 cents; a trip from Stadium Armory to Foggy Bottom would go from 60 cents to 70 cents.

Under the 22-percent suggestion, the minimum rush-hour fare for a three-mile trip would be 55 cents, and 11.5 cents would be charged for each additional mile. The fare from Brookland to Farragut North would jump from 55 to 65 cents; the fare from Stadium-Armory to Foggy Bottom would increase from 60 to 75 cents.

There would be no charge in the present 50-cent off-peak fare for all trips, regardless of length, which is charged at mid-day, at night and on weekends and holidays.

Fares for the elderly and handicapped would continue to be half the rush-hour fare, up to a maximum of 50 cents per trip.

The District of Columbia would continue its policy of reducing all rush-hour fares by 10 cents for all riders entering or leaving the subway at the Minnesota Avenue or Deanwood stations. Passengers using the Benning Road station, on the Blue Line segment scheduled for operation late this year, would also receive the 10-cent discount. The discount does not apply to the 50-cent off-peak fare. Rail-Bus Transfers

Transfers from bus to subway would continue to be prohibited.

Riders may transfer free from subway to bus within the District of Columbia.

At Maryland stations, the rail-to-bus transfer price would increase from 10 cents to 15 cents at all times, plus zone charges.

At Virginia stations, three proposals are under consideration. One would eliminate the rail-to-bus surcharge and make the transfer free, although zone charges would remain. Another would eliminate transfer privileges and charge full bus fares. The third would require a minimum 30-cent surcharge plus zones charges. Passes

A pass for use exclusively within the District of Columbia is being proposed. It would sell for $10, be good for two weeks, and allow unlimited bus trips within the District, as well as $6 worth of subway trips.
