...concern. On Monday night an atmospheric inversion settled over the city. The sky turned reddish-brown, as clouds of ash, soot, and foundry dust produced by the city's factories were trapped beneath. By Tuesday, the pollution level had risen to 771 micrograms of particulate matter per cubic meter of air, nearly four times the level considered safe by the Environmental Protection Agency...
...Government into contracts that do not allow for changes in either technology or demand. Under terms of the agreements with four helium producers (Northern Helex, Cities Service Helex, National Helium and Phillips Petroleum), the Bureau of Mines must annually buy from them increasingly large amounts of helium (4 billion cubic feet this year) at $12 per thousand cubic feet. But because of new production techniques, the companies can now produce helium, which is found in natural-gas fields, for far less than that. Furthermore, the Bureau of Mines is committed under law to sell the gas at $35 per thousand...
...result, civilian users, who formerly relied on federal supplies, have begun to buy on the private market. (Government agencies are required to buy from the Bureau of Mines and are forced to pay the federal price of $35 per thousand cubic feet.) Helium producers, making handsome profits, have refused to renegotiate their contracts. Thus the Government has been forced to continue buying helium in the same quantities as were needed when it was a monopoly seller, though it has fewer customers to sell it to. Result: it has acquired a massive oversupply of the gas. The stockpile rests...
INDUSTRY emits most sulfur oxides and particulates (soot, fly ash, heavy metals). Clean air now means a maximum 80 micrograms of sulfur oxides per cubic meter of air and 75 micrograms p.c.m. of particulates as an annual mean. Both sources emit about the same amounts of nitrogen oxides, which the rules now limit to .05 p.p.m. of air. Both also contribute to photochemical oxidants, which are formed by the action of sunlight on hydrocarbons and nitrogen oxidants. The new rules limit photochemical oxidants to .08 p.p.m. of air. All this could sharply reduce present levels of air pollution. CO levels...
...Vernon-sized nuclear reactor requires about 1100 to 1200 cubic feet of water per second, all of which is heated to about 18 F above its original temperature. Although over 900 reactors are expected in the U. S. by the year 2000, just 120 of them would require more water than the total annual runoff from the continental U. S. Coastal power stations which use ocean water are being offered as a solution to this problem...
