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.
