$10-Billion Transit Plan Advances

The Senate Appropriations Committee on Friday approved a bill allocating $10.6 billion to government transportation programs, although the Reagan Administration has threatened to veto the measure.

The plan for fiscal 1989, sent to the Senate floor on a voice vote, also would allow spending of an additional $14.4 billion of the revenues collected each year for aviation, highway and mass transit programs. The fiscal year begins Oct. 1.

Under the legislation, the government would spend $6.6 billion for the Federal Aviation Administration, an increase of $800 million over this year. Spending for the Coast Guard would be increased by $350 million, to $3 billion, of which $492 million would be set aside for drug-smuggling interdiction work.

Continuing the perennial dispute between the Administration and the Democratic-controlled Congress, the committee ignored a White House request that spending on mass transit be slashed and that federal aid to Amtrak, the passenger rail service, be ended.

James C. Miller III, director of the Office of Management and Budget, in letters sent to committee members Thursday, said he would urge President Reagan to veto the legislation.
