ys of the ground water environment under operating and accident conditions, with respect to present and future users, are important factors in site selection. DG-4034, Page 8 Industrial, Military, and Transportation Facilities Accidents at present or projected nearby industrial, military, and transportation facilities may affect the safety of a commercial nuclear power station. Accidents at nearby industrial facilities, such as chemical plants, refineries, mining and quarrying operations, oil or gas wells, or gas and petroleum product storage installations, may produce missiles, blast overpressure, fires, flammable vapor clouds, or toxic chemicals. These accidents may affect the station itself or the station operators in a way that jeopardizes station safety. Accidents at nearby military facilities, such as munitions storage areas and ordnance test ranges, may threaten station safety. An accident during the transport of hazardous materials (e.g., by air, waterway, railroad, highway, or pipeline) near a commercial nuclear power station may generate blast overpressure, missiles, and toxic or corrosive gases that could affect safe station operation. The consequences of such an accident will depend on the proximity of the transportation facility to the site, the nature and maximum quantity per shipment of the hazardous material, and the layout of the nuclear station. Airports and airways including military training routes and military airspaces pose hazards to nearby commercial nuclear power stations. Potential threats to stations from aircraft include aircraft impact and the secondary effects of a crash (e.g., fire). Ecological Systems and Biota The potential impact of station construction and operation on biota (plant or animal species) and on their habitats and supporting ecological systems needs to be assessed to fulfill NEPA requirements. Considerations may include preservation of habitats and migratory routes, as well as direct impacts (e.g., entrainment,
