Most wasproducers amounted to 2.2 million tons in in the form of rock and solar salt. 1979, as all types of salt displayed increases. Fifty companies produced salt at 90 plants in 17 States in 1979. Over 1 million tons of salt was sold or used by 11 of the companies, representing 81% of the national total. The five leading States in the amount of salt sold or used follow: State Percent 1978 of total 1979 Louisiana 33 31 Texas 21 25 NewYork 14 14 Ohio 9 9 Michigan 9 7 Total 86 86 The percentage of salt sold or used by domestic producers in 1978 and 1979 by type follows: Percent 1978 1979 Saltinbrine 52 Minedrocksalt 34 Vacuum-pan salt and graineror open-pan salt 9 Solar-evaporated salt 5 Cargill, Inc., announced plans to expand evaporated salt capacity by 40% at Breaux Bridge, La., and rock salt capacity by 50% at Lansing, N.Y.2 The company acquired Leslie Salt Co., the Nation's principal solar salt operation, based at Newark, Calif., for nearly $30 million in 1978.~ Great Salt Lake Minerals and Chemicals Corp. completed construction of a new salt plant at Ogden, Utah, in 1979. The facility has tripled the company's processed salt capacity.4 International Salt Co. reported capacity increases at Avery Island, La., with the introduction of new loading and hauling units, and at Retsof, N.Y., because of improvements in underground transportation and hoisting.~ Carey Salt Co. was purchased by Processed Minerals, Inc., a wholly owned subsidiary of Canadian Pacific Investments, Ltd.6 Mild weather at the onset of the 1979-80 winter diminished the possibility of a deicing salt shortage in the Midwest that was expected because of several factors affecting rock salt availability in 1979. An explosion closed the Patterson, La., mine of Cargill, Inc., from early June to the beginning of December. Production at Morton Salt Co.'s Weeks, La., operation was reduced coincident with the conversion of the mine to a strategic petroleum reserve storage site prior to the completion of a replacement salt mine. A strike of 3 mQnths' duration occurred at International Salt Co.'s Cleveland, Ohio, site. In addition rock salt stockpiles were reduced by heavy demand in the previous winter, and transportation was reportedly difficult to obtain. CONSUMPTION AND USES Domestic consumption of salt increased to 47.5 million tons in 1978. In the chemical industry production of chlorine and caustic soda increased, but synthetic soda ash output declined because of reduced capacity. Heavy demand for highway deicing salt at the beginning of 1978, coupled with transportation difficulties caused by frozen waterways, created shortages in certain regions. In 1979 salt consumption in the United States reached an estimated 50.3 million tons, primarily because of greater chlorine and caustic soda output. The decline in salt demand for synthetic soda ash production continued as only one plant remained onstream. Concern over the aforementioned possibility of a deicing salt shortfall prompted many consumers to attempt to secure supplies well in advance of the 197980 winter season. Salt usage by the water-conditioning and oil industries continued to climb significantly in both years. STOCKS
