1966 – Federal Metal and Nonmetallic Mine Safety Act passed

The Federal Metal and Nonmetallic Mine Safety Act of 1966 (Public Law 89-577) set up procedures for developing safety and health standards for metal and nonmetal mines. Standards could be advisory or mandatory. One annual inspection was required for underground mines, and Federal inspectors were given the authority to issue notices of violation and orders of withdrawal. Education and training programs were also expanded.
