By Robert T. MacMillan1 
 Production of salt in 1972 declined slightly ' for the second consecutive
year following a 12-year period of steady growth. The quantity actually sold
or used by producers, however, increased 2% compared with the 1971 figures.
This increase was attributed to a large inventory of unused rock salt carried
over from the previous year. The average value of salt sold or used in 1972
declined 4% compared with the 1971 value. 
 Exports increased 30% in quantity and 33% in value compared with correspond-
ing 1971 figures. Imports, however, declined 10% in quantity and 17% in value.
 Legislation and Government Programs. 
—Tightened antipollution standards set by Federal and State environmental
pollution control agencies resulted in the final closing of Olin ' Corp.'s
chlorine-caustic soda plant, Virginia's lone salt producing company. The
cost of modernizing the plant to meet more stringent effluent standards was
considered too high, and pToduction was phased out early in 1972.

DOMESTIC PRODUCTION 
 Seventeen States recorded salt production in 1972. The two leading States,
Louisiana and Texas, produced 52% of the total output. Ohio, New York, and
Michigan contributed 36%. Salt was produced by 54 companies at 96 plants
in the United States and Puerto Rico in 1972. Eleven companies, each producing
more than 1 million tons in 1972, operated 42 plants and accounted for 85%
of the total salt output. Eighteen companies with a production of less than
1 million tons but more than 100,000 tons operated 28 plants and accounted
for 14% of the total production. Twenty-five other companies whose mdi- 
vidual production was less than 100,000 tons operated 26 plants and supplied
the remaining 1% of the total salt output. 
 Fifteen plants, each with a production of over 1 million tons, accounted
for 64% of the total salt output. Ten plants, each producing between 500,000
and 1 million tons, accounted for 14% of the total. The remaining 22% was
supplied by 71 plants. 
A trend toward consolidation in the salt industry continued with Solar Salt
Co. of Utah being sold to American Salt Corp. Dakota Salt Co. of North Dakota
