ENTUCKY—1990 217THE MINERAL INDUSTRY OF KENTUCKY This chapter has been prepared under a Memorandum of Understanding between the U.S. Bureau of Mines, U.S. Department of the Interior, and the Kentucky Geological Survey for collecting information on all nonfuel minerals. By L. J. Prosser, Jr.,1 and Garland R. Dever, Jr.2 The value of nonfuel mineral production in Kentucky in 1990 of $359 million was the highest reported in State history. Substantial increases in output and value were reported for clays, lime, and construction sand and gravel. Nationally, Kentucky ranked 30th in the value of nonfuel mineral production. The State was a major producer of aluminum and coal, ranking second in output in the United States in both of those commodities. TRENDS AND DEVELOPMENTS Traditionally, Kentucky's mining industry has been dominated by coal. The State has produced in excess of 160 million short tons of coal each year since 1984. In 1990, about 179 million tons was reported by the Kentucky Department of Mines and Minerals. The State has accounted for about 20 % of U.S. production annually since 1966. Future coal production in Kentucky was expected to be affected by enactment of amendments to the Federal Clean Air Act late in 1990. The amendments would ~ require reduced sulfur dioxide emissions ~ from coal-burning plants and were ~ expected to result in increased competition between Kentucky coal and the low-sulfur coal mined in the Western ~ United States, particularly in Wyoming. ~ The installation of scrubbing systems for flue gas desulfurization at coal-fired plants, however, would permit the continued burning of higher sulfur coals and would increase the demand for lime and limestone used as reagents in sulfur dioxide removal. During the past 5 years, the State's industrial mineral producers and metal TABLE 1 manufacturers increased production and expanded operations. In 1990, Kentucky was among the leading States in production of a number of mineral commodities, ranking 1st in ball clay, 2d in aluminum, 4th in lime, 6th in ferroalloys, and 10th in crushed stone. LEGISLATION AND GOVERNMENT PROGRAMS In 1990, the Kentucky Revenue Cabinet began sending assessment notices for ad valorem taxation of unmined coal reserves in Kentucky. The Cabinet started its assessment program in 1989, after the Kentucky Supreme Court ruled in March 1988 that the State must tax unmined coal at the same rate as other real estate. That decision raised the State rate from one-tenth of 1 cent for every $ 1 00 of assessed value to about 2 1 cents NONFUEL MThIERAL PRODUCTION IN KENTUCKY' xx 118,616 XX XX 344,979 XX ~Estimaied.
