Accidents (4) involving LPG cars were only considered during train movements in the rail yards <br />since no (4) lifting occurs with this car type. Overall, risk of transporting LPG was found to be <br />comparable to LNG within the rail yards and intermodal facilities and was found to be slightly <br />higher than LNG on the proposed routes. The overall risk for LNG ISOs in the Hialeah yard is <br />significantly influenced by the contribution from lifting risk, which is not present for LPG. The <br />risks between LNG and LPG are summarized in the tables below for mainline movements and <br />for the Hialeah facility. <br />Comparison of risk metrics for LNG ISOs and LPG rail car mainline train movements. <br />(4) <br />Comparison of risk metrics for LNG ISOs and LPG rail car movements and LNG ISO <br />lifting in the Hialeah Yard. <br />Risk Metric <br />Train Speed < 25 mph Train Speed from 25 — 60 mph <br />Risk Metric <br />SR Integral (total risk, yr-) <br />LNG <br />LPG LNG <br />LPG <br />SR Integral (total risk, yr') <br />Maximum Distance to Zone 1 - 1 x 10 IR (ft) <br />Maximum IR (y(') <br />Maximum Distance to Zone 2 - 1x10 IR (ft) <br />(4) <br />Maximum Distance to Zone 1 - 1x10-0 IR (ft) <br />(4) <br />Maximum Distance to Zone 2 - 1x10 IR (ft) <br />(4) <br />Maximum Distance to Zone 3 - 3x 10 IR (ft) <br />(4) <br />9 <br />(4) <br />Comparison of risk metrics for LNG ISOs and LPG rail car movements and LNG ISO <br />lifting in the Hialeah Yard. <br />Risk Metric <br />LNG <br />LPG <br />SR Integral (total risk, yr-) <br />Maximum IR (y(') <br />Maximum Distance to Zone 1 - 1 x 10 IR (ft) <br />Maximum Distance to Zone 2 - 1x10 IR (ft) <br />(4) <br />Maximum Distance to Zone 3 - 3x10 IR (ft) <br />(4) <br />(4) <br />E.2.5 Sensitive Targets for Routes 1 and 2 <br />The FRA requested that FECR perform an analysis of potentially sensitive establishments along <br />the proposed railway routes. There is no current regulatory quantitative risk criteria for Individual <br />Risk or Societal Risk of LNG transportation by rail, and the criteria used here were developed <br />from those applicable to stationary LNG plants. For stationary LNG plants, NFPA 59A does not <br />permit sensitive establishments, such as churches, schools, hospitals, and major public assembly <br />areas, to be located within an Individual Risk contour greater than 3x 10-7 per year (called Zone <br />1308194 001 - 5691 XXII <br />
