696 MINERALS YEARBOOK, 1972 Actual drawdown of government stocks during 1972 was 44,738 tons, leaving a total of 1,085,871 tons remaining in the stockpile on December 31. Of the total uncommitted inventory at yearend 547,615 tons was in excess of the 530,000-ton objective. GSA concluded contracts in May with primary producers for the disposal of 575,000 tons of surplus stockpile lead. Under terms of the contracts producers were obligated to purchase metal at the rate of 50,000 tons per year subject to suspension during quarters when producers' stocks exceed one-tenth of the preceding year~s shipment of primary metal. The long-term contracts were amended at yearend by reducing the point of suspension to one-twelfth of the preceding year's shipments and increasing the purchase requirement to 55,000 tons per year. The new rates were to become effective January 1, 1973. A bill (H.R. 16388) ' to provide for an adequate supply of lead and zinc for consumption in the United States from domestic and foreign sources was introduced in August and referred to the Committee on Ways and Means. The bill included a proposal to increase tariffs on lead in impor.ted concentrates, lead and zinc unwrought and wrought metals, lead and zinc waste and scrap, and manufactures of these metals when exceeding specified urniting quantities. The bill also provided for revising the quotas for lead and zinc in concert with changes in the annual consumption. The proposed act was designed to implement the Mining and Minerals Policy Act of 1970 by encouraging private enterprise. No further action was taken on the bill by the 92d Congress. Bills (S. 3136, H.R. 12958) were introduced in the 2d Session, 92d Congress to regulate ' the amounts of lead and cadmium that may be released from glazed ceramic or enamel dinnerware; other ' bills introduced in the Congress relating to the use of lead included the following: S. 607—which would reduce the amount of lead contained in lead-based paints for residential use and establish procedures to minimize hazards of lead-based paint in any existing housing; H.R. 15937—which would provide performance standards for emission control devices to reduce air pollution from used vehicles, which could affect the use of lead in gasoline. The enactment of the Noise Control Act of 1972, which sets limits on noise emission, could stimulate the use of lead as a noise suppressing material in construction and other equipment. On February 23 the Environmental Protection Agency (EPA) published guidelines Table 1.—Salient lead statistics (Short tons unless otherwise specified) 1968 1969 1970 1971 1972 United States: Production: Domestic ores, recoverable lead content Value thousands_ Primary lead (refined): From domestic ores and base 359,156 $94,903 509,013 $151,635 571,767 $178,609 578,550 $159,679 618,915 $186,046 bullion From foreign ores and base bullion Antimonial lead (primary lead content) Secondary lead (lead content) Exports of lead materials excluding scrap.
