Potential enviornmental, health, and safety (E,H and S) concerns associated with all phases of the photovoltaic (PV) energy system life cycle are identified and assessed. E,H and S concerns affecting the achievement of National PV Program goals or the viability of specific PV technologies are emphasized. The report is limited to near-term manufacturing process alternatives for crystalline silicon PV materials, addresses flat-plate and concentrator collector designs, and reviews system deployment in grid-connected, roof-mounted, residential and ground-mounted central-station applications. The PV life-cycle phases examined include silicon refinement and manufacture of PV collectors, system deployment, and decommissioning. The primary E,H and S concerns that arise during collector fabrication are associated with occupational exposure to materials of undetermined toxicity or to materials that are known to be hazardous, but for which process control technology may be inadequate. Stricter exposure standards are anticipated for some materials and may indicate a need for further control technology development. Minimizing electric shock hazards is a significant concern during system construction, operation and maintenance, and decommissioning.

Newsletter of the Texas Bureau of Disease Control and Epidemiology discussing the news, activities, and events of the organization and other information related to health in Texas.

This paper reviews the initiatives of the Reagan Administration to control cost overruns during the last 2 and a half years and the actions taken by the Congress to strengthen its oversight role. Particular attention is directed at the critical need to enhance management incentive and accountability at all level of the acquisition process. If recently instituted reform in the Department of Defense fail to control cost overruns, pressure may grow for a more sweeping and radical approach. Serious consideration in such an event might even be given to removing responsibility for weapons acquisition management for the military service and assigning it to a civilian-operated supply agency.
