pipelines are not symbolic targets with political, historical, and cultural significance, they are potentia~ targets for terrorist actions. Natural gas utilities and local emergency responders are generally well prepared to deal with natural gas breaks, because such incidents occur frequently enough to have well-standardized response procedures. Evacuations for natural gas distribution system pipeline ruptures are generally limited to the immediate area of the break. The Kinder Morgan petroleum pipeline transports refined petroleum products, including gasoline, diesel fuel and both commercial and military jet fuel. This pipeline runs from Portland to the Eugene terminal, with an intermediate truck-load/n9 terminal near Albany. From the terminals, petroleum products are transported by truck to customers. Major petroleum transmission lines, such as the Kinder Morgan line in Oregon, are heavily engineered and generally constructed of welded steel pipe that is strong and reasonably flexible. Major failures are rare, but may occur due to natural or human- related causes. Pipeline breaks due to natural causes may occur due to landslides or earthquakes. Earthquake induced pipe breaks for petroleum transmission lines are most likely to occur in areas of soft soils subject to liquefaction and/or lateral spreading which cause significant pipe displacements. The most likely locations for such breaks during an earthquake are on slopes of soft 9round near where pipelines cross rivers or streams. 14.7 Potentia~ Impacts of Hazardous Material Incidents The potential impacts of hazardous materials incidents on the Eugene/Springfield Metro Area are summarized below in Table 14.4 Table 14.4 Potentia~ impacts of Hazardous Mateda~ incidents on the Eugene/Springfield Metro Area Inventory Probable Impacts Most hazmat incident impacts would be Iocahzed near source of Portion of Eugene/Springfield Metro Area affected spdl, but major spills could have extensive evacuation zones and affect a significant port~on of the Eugene/Springfield Metro Area Negligible impact, except for very near incidents which revolve BuiMings explosions Streets within Metro Area Temporary street closures likely Roads to/from Metro Area Temporary road closures likely E~ectdc power Neghg~ble impact, except for very near incidents which involve explosions Negligible impacts, except for incidents which spdled hazmat into Other Utilities rivers upstream from water intakes for Eugene/Springfield water systems Potential for casualties (deaths and injuries), depending on Casualties location and identify of hazmat material(s) involved, bme of day and effecbveness of evacuations Public Review Draft: October 12, 2004 14-12
