.OUISIANA—1990 225THE MINERAL INDUSTRY OF LOUISIANA 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 Louisiana Geological Survey for collecting information on all nonfuel minerals, By Doss H. White, Jr. ,~ John Johnston,2 and W. E. Marsalis3 Louisiana's 1990 nonfuel mineral production was valued at $367.9 million. This was an $ 1 1 . 8 million decline below that reported to the U.S. Bureau of Mines by the State's mineral producers in 1989 and $215.9 million below the $583.8 million record for nonfuel mineral output established in 1980. The decrease in the 1990 mineral value below that reported in 1989 was due to a decline in sales of clays, gypsum, stone, and sulfur. Nationally, Louisiana dropped one position to 29th in nonfuel mineral value. The State, accounting for 1. 1 % of the $33.3 billion of mineral commodities produced in the United States in 1990, led the Nation in salt output and ranked second in sulfur production. TRENDS AND DEVELOPMENTS Louisiana has a sparsity of hard-rock resources because of the State's geological setting in the Gulf Coastal Plain ; surface and near-surface strata are predominantly clays, gravels, and sands. For many decades, oyster shells dredged from State lakes and coastal waters have been used as a substitute for crushed stone in the construction of road foundations. During the past several years, dredges operating on Lake Pontchartrain have supplied the bulk of the shell used in Louisiana highway construction. Shell dredging leases were issued by the Louisiana Department of Wildlife and Fisheries. In 1983, an environmental group sued the Wildlife and Fisheries Department and asked that the court declare dredging TABLE I leases illegal. Four years later, in 1987, the trial court issued a judgment stating that the leases were illegal because public bidding was not involved. In 1988, the 4th Circuit Court affirmed the decision. Later in 1988, the Louisiana Legislature passed and the Governor signed Act 41 of 1988, which authorized shell dredging without lawful leases until new leases were issued after public bidding. In September 1988, a preliminary injunction against dredging was issued by the original trial court. The injunction stated that dredging rights must be issued according to Louisiana law. On the same day the injunction was issued, the Wildlife and Fisheries and industry signed new shell dredging leases that the industry contended complied with the State bid law. In January 1990, the 4th Circuit Court issued a ruling that terminated dredging NONFUEL MINERAL PRODUCTION IN LOUISIANA' Mineral 1988 1989 1990 . Quantity Value (thousands) .
