In order to assist the process safety <br />management of the overall design, testing, and implementation project, the focus of the study <br />was to evaluate the risk _for movement of the ISO tank containers by intermodal rail <br />transportation. This Executive Summary highlights Exponent's findings in the <br />QRA. Note that this Executive Summary does not contain all of Exponent's technical <br />evaluations, analyses, conclusions, and recommendations. Hence, the main body of this report is <br />at all times the controlling document. <br />E.1 QRA Overview <br />Movements were evaluated along three proposed routes: (1) from Hialeah Yard to Port of <br />Miami, (2) from Hialeah Yard to Port Everglades, and (3) from Hialeah Yard to Bowden Yard in <br />Jacksonville. ISO Lift On/Lift Off activities and train movements were evaluated in four <br />yards/intermodal facilities: (1) Hialeah Yard, (2) Bowden Yard, (3) Port Everglades, and (4) Port <br />of Miami. <br />,308, 94.00, - 5691 x1V <br />
