; and (3) examine the effects of exposure to climate conditions across rail networks, including temperature, humidity, and any other factors that the Administrator of the Federal Railroad Administration determines could influence performance of rail tank cars and components of such rail tank cars. (c) Other factors To consider In conducting the evaluation under subsection (a), the Administrator of the Federal Railroad Administration shall evaluate the impact of a discharge of liquefied natural gas from a rail tank car on public safety and the environment, and consider— (1) the benefits of route restrictions, speed restrictions, enhanced brake requirements, personnel requirements, rail tank car technological requirements, and other operating controls; (2) the advisability of consist restrictions, including limitations on the arrangement and quantity of rail tank cars carrying liquefied natural gas in any given consist; (3) the identification of potential impact areas, and the number of homes and structures potentially endangered by a discharge in rural, suburban, and urban environments; (4) the impact of discharge on the environment, including air quality impacts; (5) the benefits of advanced notification to the Department of Transportation, State Emergency Response Commissions, and Tribal Emergency Response Commissions of routes for moving liquefied natural gas by rail tank car; (6) how first responders respond to an incident, including the extent to which specialized equipment or training would be required and the cost to communities for acquiring any necessary equipment or training; (7) whether thermal radiation could occur from a discharge; (8) an evaluation of the rail tank car authorized by the Secretary of Transportation for liquefied natural gas or similar cryogenic liquids, and a determination of whether specific safety enhancements or new standards are necessary to ensure the safety of rail transport of liquefied natural gas
