  145Asbestos 
By R. A. Clifton1 
 Shipments of asbestos (mostly chrysotile) in 1977 from mines in the United
States decreased 11% from those in 1976. Imports were 8% lower than those
in 1976 because U.S. demand continued to lag well below the peak year of
1973. 
 Canadian production in 1977 was 8% 
lower than that for 1976, and shipments from Canada to the United States
were 6% less than those in 1976. Imports from the U.S.S.R. were 1% of total
U.S. imports, and those from the Republic of South Africa accounted for 4%.

 Legislation and Government Pro. grams.—Again, no date was set
by the
Occupational Safety and Health Administration (OSHA) for the public hearings
mandatory for the proposed revisions to its asbestos standard for manufacturing.
The proposal for a permissible-exposure level of 0.5 fibers per cubic centimeter
(0.5f/cc) is well into its third year without the hearings. 
 On March 18, 1977, President Carter signed Public Law 95-12. This act repealed
the Byrd Amendment, which had exempted strategic minerals from the economic
sanctions in force against Southern Rhodesia. 
 The Consumer Products Safety Commission (CPSC) banned all consumer patching
compounds and artificial emberizing mate- 
rials that contain respirable free-form asbestos. The ban on emberizing materials
became effective December 15, 1977, and that on patching compounds becomes
effective January 16, 1978, for all such compounds manufactured after that
date. 
 On November 10, 1977, the Environmental Protection Agency (EPA) gave advance
notice of intention to propose an asbestos standard for the production and
use of crushed stone. 
 Under a new State law, all California firms manufacturing asbestos products
or using asbestos in their processes had to register that fact prior to September
1, 1977. 
 As shown in table 2, there was little change in stockpile inventories in
1977. Crocidolite was sold from the stockpile at $301 per ton.
