1153Stone By Harold J. Drake' Production of stone increased 5% from 876 million tons in 1911 to 924 million tons in 1972. Total value increased to a new high of $1.7 billion. Crushed stone accounted for more than 99% of the total volume produced, but its value was only 95% of the total value. Production of crushed stone was 922 million tons valued at $1.6 billion compared with 874 million tons valued at $1.5 billion in 1971. The main uses of crushed stone were densegraded road-base stone, 23%; concrete aggregate (coarse), 14%; cement manufacture, 12%; unspecified construction aggregate and road stone, 12%; and bituminous aggregate, 9%. Output of dimension stone totaled 1.5 million tons valued at $90.8 million. Dimension stone accounted for less than 1% of total stone output. Production of stone was reported in all States except Delaware~ Pennsylvania, with a total stone production of 67 million tons, was the Nation's leader. Other large producers, in order of output, were Illinois, Florida, Texas, Ohio, and Missouri. These six leading States produced 317 million tons, or 34% of the Nation's Output. Prices of stone generally were stable in 1972; small increases were recorded for some types of stone. The average unit valise of all stone increased somewhat. In terms of value, imports were up 29%. whereas exports declined 3%. Legislation and Government Programs. —The United Steelworkers of America on behalf of workers of the Vermont Marble Co. plant at Rutland, Vt., filed a petition requesting certification of eligibility to apply for adjustment assistance. The request was made under the President's decision of January 28, 1972, pursuant to Sec. 302 (A) (3), of the Trade Expansion Act of 1962, that workers in the domestic marble and travertine industry were eligible to apply for adjustment assistance, under chapter 3, Title LIE of this act. - The Environmental Protection Agency (EPA) continued to study - dust emissions from aggregate-producing facilities and related plants. Dust emission standards are being developed and were expected to be implemented in the not too distant future. 1 Physical scientist, Division of Nonmetallic Minerals—Mineral Supply.
