A tripartite committee to help the nation's ailing steel industry yesterday suggested no major changes in the government's handling of steel plant closings and their potential hardships on workers and the communities in which they live.

The committee also agreed that a subgroup should be set up to deal with the controversial area of international trade and possibly consider ways to keep some imported steel out of U.S. markets.

The tripartite committee members, including Commerce Secretary Philip M. Klutznick, Labor Secretary Ray Marshall and U.S. Trade Representative Reubin Askew, said that they expect to have all recommendations for the president by the third week of August. The committee had been expected to present those reports today.

A report on community and labor adjustment assistant recommended further use of the Commerce and Labor department's adjustment assistance committees, established in December when U.S. Steel and Jones & Laughlin closed steel plants.

The committee's draft report on steel imports suggested further discussion on subjects such as monitoring the promptness and effectiveness of U.S. trade law enforcement and the problems of non-market economies.

The committee yesterday recommended that a smaller group decide what can legally be done to help the steel industry compete with exports. Suggestions included modifying the trigger-price mechanism and laws that affect the numbers of imports.
