The PHS reorganizations of 1966–1973 were particularly turbulent for occupational health, as the organization would pass through seven operating agencies and bear four names during this time. In January 1967, the first wave of the reorganizations broke up the Bureau of State Services into three components, and the Division became the Occupational Health Program of the National Center for Urban and Industrial Health, which was part of the Bureau of Disease Prevention and Environmental Control. The National Center for Urban and Industrial Health also included programs for solid wastes, injury control, water supply and shellfish, and arctic health. As each national center was to be centralized in a specific city, the Occupational Health Program's administrative staff moved from Washington, D.C. to Cincinnati. Also, the Appalachian Laboratory for Occupational Respiratory Diseases was established in Morgantown, West Virginia in 1967 as an outgrowth of the coal pneumoconiosis studies.
