Lifelines are vital to the health and safety of the community and the functioning of an urban and industrialized society. Lifelines are critical for the emergency response and recovery of a community after a disaster. Lifelines include electric power, communications, transportation (highways, airports, railroads and harbors), water, sewage, natural gas, and liquid fuel systems. A discussion of hospital lifelines is included here. See also the chapters on nonstructural components and highways.

This paper describes the first completely gas-turbine powered stations used for supplying primary power for military installations. The stations, with one exception, are equipped with waste-heat boilers which supply steam for use in all heating including barracks. Gas turbines were specified as the most economical means of satisfying the electric power and central heating requirements. The stations are completely self-contained with no connection to any commercial power. The gas turbines, with one exception, use natural gas as the primary fuel and No. 2 diesel fuel as standby fuel. Changeover to liquid fuel is automatic. Change back to gas is manual.

Natural gas is an increasingly vital U.S. energy source that is presently being tapped and transported across state and international boundaries. Controversy engulfs natural gas, from the hydraulic fracturing process used to liberate it from massive, gas-laden Appalachian shale deposits, to the permitting and construction of new interstate pipelines bringing it to markets. This case explores the controversy flowing from the proposed 256-mile-long interstate Nexus pipeline transecting northern Ohio, southeastern Michigan and terminating at the Dawn Hub in Ontario, Canada. As the lead agency regulating and permitting interstate pipelines, the Federal Energy Regulatory Commission is also tasked with mitigating environmental risks through the 1969 National Environmental Policy Act's Environmental Impact Statement process. Pipeline opponents assert that a captured federal agency ignores public and scientific input, inadequately addresses public health and safety risks, preempts local control, and wields eminent domain powers at the expense of landowners, cities, and everyone in the pipeline path. Proponents counter that pipelines are the safest means of transporting domestically abundant, cleaner burning, affordable gas to markets that will boost local and regional economies and serve the public good. Debates over what constitutes the public good are only one set in a long list of contentious issues including pipeline safety, proposed routes, property rights, public voice, and questions over the scientific and democratic validity of the Environmental Impact Statement process. The Nexus pipeline provides a sobering example that simple energy policy solutions and compromise are elusive—effectively fueling greater conflict as the natural gas industry booms.

NERIS is the European platform on preparedness for nuclear and radiological emergency response and recovery. Created in 2010 with 57 organisations from 28 different countries, the objectives of the platform are to: improve the effectiveness and coherency of current approaches to preparedness; identify further development needs; improve ‘know how’ and technical expertise; and establish a forum for dialogue and methodological development. The NERIS Strategic Research Agenda is now structured with three main challenges: (i) radiological impact assessments during all phases of nuclear and radiological events; (ii) countermeasures and countermeasure strategies in emergency and recovery, decision support, and disaster informatics; and (iii) setting up a multi-faceted framework for preparedness for emergency response and recovery. The Fukushima accident has highlighted some key issues for further consideration in NERIS research activities, including: the importance of transparency of decision-making processes at local, regional, and national levels; the key role of access to environmental monitoring; the importance of dealing with uncertainties in assessment and management of the different phases of the accident; the use of modern social media in the exchange of information; the role of stakeholder involvement processes in both emergency and recovery situations; considerations of societal, ethical, and economic aspects; and the reinforcement of education and training for various actors. This paper emphasises the main issues at stake for NERIS for post-accident management.

<p>Waiho – (verb) (-ngia,-tia) <i>to let be, leave alone, put, place, ignore.</i></p><p>SH6 Waiho Bailey Bridge is located just south of Franz Josef township in the South Island of New Zealand and is a critical connection for the West Coast. The Bailey bridge was first constructed in 1990 and has since been raised and extended three times due to significant aggradation of the riverbed. During a massive storm event on March 26, 2019 the northern abutment and northern- most pier were washed out leading to collapse of several spans of the bridge. The cost caused by the loss of the bridge was estimated to be in the order of $2-3M per day. Consequently, there was intense pressure on Waka Kotahi NZ Transport Agency to restore access across the river.</p><p>As Team Leader and Deputy Team Leader of the West Coast Bridge Management Contract, Jeremy Waldin and Ben Baty led the $6.5M emergency recovery managing an emergency response team which worked across multiple organisations to recover this 170m long bridge in just 18 days.</p>
