A review of the data available indicates that world demand in 1971 exceeded world production of phosphate rock. This caused a much needed reduction in producers' stock inventories. Estimated total world sales for consumption in 1971 were nearly 5 percent greater than in 1970, whereas world production increased less than 2 per

cent.

Although the average value of domestic phosphate rock remained steady at $5.26 per ton for that sold or used, phosphatic fertilizers were much more in demand

than in the previous 3 years. The demands for phosphoric acid and ammonium phosphates were especially good. However, because of rising costs and decreasing demand for industrial purposes, elemental phosphorus producers were not as fortunate as those producing for the fertilizer market.

Legislation and Government Programs. -Most legislation and Government actions during the year were related to environmental problems. Perhaps the most publicized legislation has been concerned with phosphorus in detergents. Federal legislation was introduced in Congress to ban phosphates in detergents, but by yearend none of the bills introduced had been enacted into law. Because newly developed substitutes for phosphates in detergents were stated to be health hazards by Federal officials, housewives were advised to continue to use phosphate detergents. This advice in September did not deter some States, counties, and cities from passing laws to limit or ban the use of phosphate detergents. Indiana was the first State to ban almost all phosphate detergents. The law, effective January 1, 1973, will outlaw the sale, use or disposal of any detergent

"containing more than 3 percent phosphorus by weight."2 A listing of other State and local legislation restricting the use of phosphate detergents and a discussion of the subject was published.3

On July 25, 1971, Florida Attorney General Robert Shevin filed suit in U.S. District Court, Washington, D.C., charging that the Secretary of the Interior, the Secretary of Agriculture, the Director of the Bureau of Land Management, and the Chief of the Forest Service had committed "unconstitutional and illegal action" by approving phosphate prospecting permits in the Osceola National Forest. The court was asked for an injunction to prevent the issuance of permits to mine in the Forest and to order the Federal agencies to undertake thorough ecological and economic studies of the effect of phosphate mining in the Osceola National Forest.

A public hearing was held July 27 and 28 in Ventura, Calif., concerning the environmental impact of mining phosphate in Los Padres National Forest. United States Gypsum Co. proposed developing a phosphate deposit on Pine Mountain in the national forest and applied for a preferential right lease to mine and process the mineral. An environmental statement, pursuant to Sec. 102(2)(c) (Public Law 90-190, 83 Stat. 852) was directed to be prepared by the Department of the Interior's Bureau of Land Management and the Department of Agriculture's Forest Service.
