US nonfuels minerals policy

Nonfuels minerals policy in the USA flows from the differential and unique reactions of these industries to general economic policies in the areas of taxation, land use, environment, and international trade. To search for nonfuels minerals policy as direct statements by the US government on nonfuels minerals is futile. Nevertheless, the industries are unique in many characteristics, and the application of these general policies to the minerals industries creates unique situations. This uniqueness has been recognized by a virtually constant policy review over the past 10 years. The current effort is just beginning, and to prejudge now the outcome of this discussion is premature. However, it is not premature to argue that because of the uniqueness of these industries, it may be expected that their problems will be receiving public attention for many years to come.     

Regional intergovernmental institutions: Participation benefits and costs

Evaluators frequently cite the absence of effective participation by constituent governments and the need for consensus or even unanimity prior to action as the causes of poor performance by regional resource management institutions. Major governments either will not join the regional institution, will not participate even if legally members, or will exercise a veto over many important management projects.This paper examines the variables that may cause these problems and provides an improved understanding of why rational political actors would act in ways that inhibit the efficient management of resources. Among the principal variables determining participation are expected benefits of collective decisions, perceived losses of autonomy and representation, the number and homogeneity of other participants, decision costs, and the decision rule used to determine actions. Analysis of these factors suggests why consensus and unanimity decision rules are frequently chosen and why participation is usually limited.     

Polychlorinated chemical residues in fish from major watersheds near the Great Lakes, 1979

Over 50 non-PCB polyhalogenated organic chemicals have been identified by GC/MS in fish from the Great Lakes and other major watersheds near the Great Lakes. p,p′-DDE, hexachlorobenzene, and components of tech-chlordane were the most frequently found chemicals. Also described are advances in sample preparation methodology which allow the identification of many frequently occuring unusual chemicals. Several chemicals not previously reported in environmental samples are identified.     

FUTURE SOURCES OF COOLING WATER FOR POWER PLANTS IN ARID REGIONS1

ABSTRACT: Electric generation facility water requirement will increase substantially in the future in the Western United States because new power plants are to be constructed at inland sites rather than on the coast. At the inland locations, power plants will have to compete with agriculture and public users for fresh water supplies, and will be constrained by environmental legislation to dispose of cooling waste water in lined evaporation ponds. The various options for power plant cooling are analyzed in respect to cost, water consumption, and environmental hazard, and also in respect to their compatibility with existing state and federal regulations. Several proposals for balancing the water requirements of various users in water-scarce areas are reviewed and criticized.
