Virginia Gov. Gerald L. Baliles, fulfilling a campaign pledge to seek better management and enforcement of environmental programs, today named John W. Daniel II to the new cabinet position of secretary of natural resources.

The position was created when the General Assembly, at Baliles' request, divided the position of secretary of commerce and natural resources into two secretariats, one for economic development and the other, natural resources.

Asked if the new secretary will lead a crackdown on polluters, Baliles said "the objective should be cleanup. Where deliberate violations occur, swift enforcement is in order."

Baliles said he wants Daniel to recommend how to "renew and strengthen" the cleanup of the Chesapeake Bay. The governor said he is concerned that the federal government may retreat from its commitment to the bay cleanup, as it is "backing away from its commitment to Metro."

The Reagan administration has said it does not support federal funding for completion of Metro, the 103-mile subway system in the Washington area.

The governor also said he wants Daniel to review water quality conditions with the state Water Control Board, the primary agency charged with keeping the state's waters clean. Baliles said he is "not satisfied with the reliability of the sampling system," especially on metals and toxic organic substances, and wants "corrective action taken."

Daniel, 36, who becomes the seventh member of the Baliles cabinet, is a lawyer who has been deputy secretary of commerce and resources since January. He was a special assistant to Bailies when the governor was attorney general. His appointment to the $78,412-a-year position is effective July 1.

As a staff attorney to the division of legislative services from 1977 to 1982, Daniel was counsel to the state water study commission and legislative committees that dealt with conservation, water, mining and mineral resources.

A Richmond native and father of two young children, Daniel said he and his family are backpackers who recycle cans and use phosphate-free liquid soap.

He said he plans to "debate" with Economic Development Secretary Richard M. Bagley the need to balance environmental concerns with economic growth.

Baliles named another of his former assistants, Cynthia V. Bailey, to be the $41,830-a-year director of the new Department of Waste Management.

The agency, another Baliles idea, consolidates the waste facilities siting council, the Health Department's division of solid and hazardous waste management, and the state's solid waste commission.
