provisions. In 1966, Congress extended coverage of the 1952 Coal Act to all underground coal mines. The first federal statute directly regulating non-coal mines did not appear until the passage of the Federal Metal and Nonmetallic Mine Safety Act of 1966. The 1966 Act provided for the promulgation of standards, many of which were advisory, and for inspections and investigations; however, its enforcement authority was minimal. Coal Act The Coal Mine Safety and Health Act of 1969, generally referred to as the Coal Act, was more comprehensive and more stringent than any previous federal legislation governing the mining industry. The Coal Act included surface as well as underground coal mines within its scope, required two annual inspections of every surface coal mine and four at every underground coal mine, and dramatically increased federal enforcement powers in coal mines. The Coal Act also required monetary penalties for all violations, and established criminal penalties for knowing and willful violations. The safety standards for all coal mines were strengthened, and health standards were adopted. The Coal Act included specific procedures for the development of improved mandatory health and safety standards, and provided compensation for miners who were totally and permanently disabled by the progressive respiratory disease caused by the inhalation of fine coal dust pneumoconiosis or "black lung." In 1973, the Secretary of the Interior, through administrative action, created the Mining Enforcement and Safety Administration (MESA) as a new departmental agency separate from the Bureau of Mines. MESA assumed the safety and health enforcement functions formerly carried out by the Bureau to avoid any appearance of a conflict of interest between the enforcement of mine safety and health standards and the Bureau's responsibilities for mineral resource development. (MESA was the predecessor organization to MSHA, prior to March 9, 1978.) Mine Act and creation of MSHA More recently, Congress passed the Federal Mine Safety and Health Act of 1977, the legislation which currently governs MSHA's activities. The Mine Act amended the 1969 Coal Act in a number of significant ways, and consolidated all federal health and safety regulations of the mining industry, coal as well as non-coal mining, under a single statutory scheme. The Mine Act strengthened and expanded the rights of miners, and enhanced the protection of miners from retaliation for exercising such rights. Mining fatalities dropped sharply under the Mine Act from 272 in 1977 to 45 in 2014. The Mine Act
