Between 1960 and 1970, the BEE field grew from around 100 to 150. However, beginning in 1970, with the formation of the Occupational Safety and Health Administration (OSHA), the U.S. Environmental Protection Agency (EPA), and the Nuclear Regulatory Commission, the career field experienced an exponential growth in Federal regulations. These laws require BEEs to monitor Air Force operations for their effects on personnel and the environment. Several major catastrophes and other events focused keen Congressional interest on environment, safety and occupational health (ESOH), leading to new, mandatory compliance programs. Love Canal, Bhopal, atmospheric ozone depletion, and other incidents spawned new laws governing the Installation Restoration Program; Hazard Communication; community-right-to-know; Process Safety Management; and hazardous material inventory, control and reduction. These have continually driven additional, corresponding requirements for BEEs.
