Steven A. Grossman, who has been majority counsel and health director of the Senate Labor and Human Resources Committee for the last three years, is expected to be named deputy assistant secretary for health in the Health and Human Services Department. Grossman originally had been slated to join HHS as associate administrator for policy of the Health Care Financing Administration. But when HCFA chief Carolyne K. Davis resigned, HHS officials decided to allow the next administrator to fill that slot.

At the Agriculture Department, Harris D. Blake, a Pinehurst, N.C., businessman and twice an unsuccessful Republican candidate for Congress, has been appointed associate administrator of the Farmers Home Administration.

Blake is president of Colonial Abrasives, a manufacturing company, and owner and developer of a shopping and professional center, an industrial park and a retirement village in Pinehurst. In 1982 and 1984, he ran unsuccessfully against Democratic Rep. W.G. (Bill) Hefner. Michael E. Brunner left the post last fall to return to the private sector.

Donald Derman, assistant secretary of transportation for budget and programs since May 1981, is resigning, effective Sept. 1. Derman will become vice president of the Washington office of Canyon Analysts, a policy analysis consulting firm. Derman has been in government for more than 30 years, serving previously at the Office of Management and Budget, the Atomic Energy Commission and the Office of Economic Opportunity.
