Mineral Depletion Allowances and U.S. Import Dependence.
MISSING :13 pages
This Bureau of Mines report examines the percentage depletion allowance rate structure in relation to several criteria that are indicative of U.S. mineral import dependence. These criteria are the minerals considered as strategic and critical for stockpiling purposes, the ratio of reserves to forecast cumulative demand (1976- 2000) for selected minerals, and the U.S. Net import reliance as a percentage of apparent consumption (1978), also for selected minerals. In general, it was found that there does exist a direct, although not perfect, relationship between the percentage depletion allowance rates and the degree of import dependence as indicated by these three criteria. The higher percentage rates tend to be associated with those minerals for which the United States is, or will likely be, heavily dependent on foreign sources. In addition, a basic discussion of the mineral depletion allowance is provided, including numerical examples illustrating the computation of the allowance under several assumptions. Also, the percentage depletion allowance rates for individual minerals are tabulated.
