%
Shipment* of asbestos in the United Sute* inceased leas *ha 1% but estab lished anotha record h'gh in 1972. Thee was no nadily apparent single reason that could explain the increased demand for as bestos. Imports were 3% above 1971 levels.
The world's Iargmt producer, Canada, inceased shipments to its largot nn^, the United States, by 10%; its total ship, meats wee 3% over the 1971 total.
Legislation and Government Programs. --The Environmental Protection Agency (EPA) had not published its asbestos emission standards by ymrend. but their
latest proposal recognised the adequacy of Bureau of Mines* controls in mines and mills and would only control visible nislions from mill effluent gases. In 1972 the Goieral Services Administration (GSA) re duced government inventories by disposing of 1.040 short tons of amosite. 11.473 tons of anddolice, and 656 tons of cbrysodle. The strategic grades of asbestos formerly under the Rhodesian Sanctions began to -appear again on the U-S. market.

Environmental Impacts--The etpected toe Office of Safety and Hmlth Adminis I effects of smroaseatal regulations on the tration (OSHA) of the Department of
asbestos market were not apparent in 197 Labor did >t promulgate its regulations The effect may just be postponed, bemuse uadi June 7. 1972. and EPA had not pro*

mulgated its regulation by vearend. The
OSHA Threshold Limit Value (TL.V) w tained its previous emergency value of five fibers greater than 5 micrometers in length per milliliter. The five fiber TLV is sched uled for reduction to two fibms in 1978.
This schedule might be shortened if union and activist prssures continue.
The final prepubliation propools for
EPA regulations differed gratly from the originals aa far as asbestos mining was
concerned. The mine were omitted en tirely as not needing EPA regulation, and the'only standard applicable to mills petained to "visible emissions to the outside air.**
Some State, having written acceptable regulations, are now the environmental control regulating agency, with their regu lations superseding, at least partially, those of the Bureau of Mines. OSHA and EPA.
DOMESTIC PRODUCTION
U-S. mines shipped leas than 1% more asbotos in 1972 than in 1971. The value inerased 10%. Four States produced asba ins; California, with S9%, was the leader, followed in order by Vermont. .Arizona, and North Carolina.
The California segment of the asbestos industry continued to grow, with a 4% in
crease in production to 90,96? tons, and was led by the Pacific Asbestos Corp. mine in Calaveras County. The largest produc ing County was Fresno, with the Coalinga Asbotos Co- Inc. and Atlas Asbestos Corp. mines. Union Carbide Corp. had significant
production in San Benito County. The State's Increased production realized an $367,229 increase in value.
The GAF Corp. mine in Orleans County, Vl, remained the U-S. asbestos mine with the highest production and highest prod uct value. With only the Jaouays Mining Corp. mine in Gila County operating again in 1972. Arizona production increa#ed 2%. The production in North Car olina of Powhatan Mining Co. declined another 14% in 1972. U-S. asbestos produc ers and mine sites are as follows:

\ CONSUMPTION AND USES
la the 100th year of commociai asbestoe use in the United Sutea, some new dtfsreitive data on consumption have been col* lotted. These data, because they were collected on a greatly revised form from aa expanded list of consumers, bear so re* lationship to the estimatm of previous yean, and comparisons are inappropriate. They are shown in table 5. The chrysotile data hi the table have been adjusted to re* Sect 95% of the apparent consumption. The flthrr data are presented as reported.
It is no surprise that with a few thou* sand known end uses, 15% of consumption fails into minor categories or *Otbm.'' The eight major uses are coascructioa 42%. floor tile 11%, friction products 10%. paper 9%, asphalt felts 6%. packing and gaskets 4%. insulation 2%, and textiles 1%.
Analysis of the newly available data on U-S. consumption of asbotos will be fesdii* tated by some rather arbitrary combination of chrysotile grades. Table 4 shows these
combinations, which disregard chesaiod variances, strength, deerrimi properties, and otho differences other than uses based looaeiy on the Quebec Asbestos Mining As sociation standards.
Crudes, and Groups 1, 2. while not milled, have the same ultimate textile uses aa Group 3, and are combined as BM I (spinning). Group* 4 and 5 comprise BM U (shingle and paper). Groups 6 and 7 become BM III (shorts).
Note that the spinning grades (BM I) are found only hs lour of the major uses. Thee fibs comprised 3% of the reported tonnages. Sbingie aod paper grads (BM II) were 47% of the weight of the fibers reported and were in all the major uses but textiles. The remainder. 50% of the reported fibers, were shorn (SM III) and were found m every major use.
The construction field used 24% of the anchophyilice reported, and friction prod* ucts used 29%. These wre che only major uses reported, except for a tiny amount in textiles.
Sevenry-cwo percent of the amosite re* ported was used for insulation, 18% for construction, and 5% for asphalt felts.
Construction accounted for 88% of the cxoodolite and paper for 1%. ' OveaJl consumption in 1972 increased nearly ?% ov- that of 1971, with no usage trends apparent

bate was expected to remain unchanged. Prices for Arizona chrpotile asbestos
have remained unchanged since August 1* 1968. Quotations. LqJj. Globe, were as foi* lows:
The inerased demand for asbmtos used in cement products (groups 5. 7) resulted in greater price increases in these categories. The last price rise for British Columbia emphasizes this poises

WORLD REVIEW
'
.Treod analyses such as those shown in
figure 1 <an reveal a great deal about the
change becoming apparest in the world
market. The data were derived by using
all the information available for the
last 10 yean to establish trends by linear
regression analysis. The full lOyear figures
were available for the United States and
and at least 4 yean were available
for each of the other countries.
If each of the major consuming coun
trie kept a near-constant share of an ex*
panding market, the result would be a
straight line, as shown by Canada. The
'U.S.SJL and Japan typify those countries
whose consumption rate has tnmeased
faster than the world production rate. The
United States and the United Kingdom
have gone the opposite way.
'
The United State* with a remarkably
stable consumption rate, is taking a
***n~r share of the etpanding market,
and it is apparent that it win soon be
supplanted by the U-S-S-R. as the world's
largest consume, if this has not already
happened.
Tile <arn'* kind of analysis of
data oa also be informative, as shown in
figure 2. Canada is both the world's largest
producer and mporter of asbestos, and a
major consuxnm as weiL The marked di-
vegence of the value and production lines
shows graphiailly the inflationary trends.
The upward slope of the production and
sport lines is indsauve of the etpanding
world market. The slight divqgence be*
tweet the production and sport lines 3*
Inmates that Canada's consumption
growth rate etaeds 'that of production
and fhag an inanasing' amount of Cana*
asbestos is bong used domatiafly.
_lTTTTniia --Thr Woodsreef mine and
wwn began operation in January 1972 and
had such promising prospects that its par*
ent Canadian company (formerly Pacific
Asbestos) is now officially Woodsreef Min
erals. Ltd. There was an official dedimtioo
in April and the mill was approaching full
capacity throughout by yearend. This c*
parity (70.000 tons per year fiber) is felt
to be inadequate, and plans for doubling
it by 1975 are underway.
Bolivia.--The 5-year United Nations De*
velopment Program (UNDP) to assist in
establishing an asbestos industry at Cocha*
bamba was terminated in 1972. UNDP
ailed the project a success and thought
the operation could function without fur*
the assistance.
Canada.--The world's larget produce
rebounded from last year's drop in produc
tion with a $% morose is 1972. Thee
wee note of aution from some industry
leaders saying that market expansion
would proceed at a slowe ram and that
new markets and ampliations wee esen*
rial to a hoitfay industry. These probably
weil-founded views, however, were offset by
the scurry of activity at producing mins
and at those with potentials. This activity
hints at a more optimistic viewpoint. Ex
ample of this are--
1. The eepassioo and modernization of
the Canadian Johns-Manvflle Go- Ltd.
mine
at Asbestos. Quebec has
not been curtailed. The project neared
completion at yearesd. and among the new
facilities was the world's larget ausho.

cance is the news that the tailing from
