Eugene -Springfield Area Natural Hazards Mitigation Plan <br />6. Appendices <br />Table 1-2 Potential Impacts of Hazardous Material Incidents on the <br />Eu ene- S rin field Area <br />Probable Impa <br />Portion of Eugene- Would be localized, except for large spills which could <br />Springfield Metro Area have extensive evacuation zones and affect a significant <br />affected portion of the Eugene -Springfield Metro Area. <br />Buildings <br />Are negligible except for incidents which involve <br />explosive and flammable materials near <br />structures. <br />Streets within Metro Area <br />Could include temporary closures. <br />Roads to/from Metro Area <br />Could include temporary closures. <br />Electric power <br />Would be negligible except for incidents <br />involving e x p l o s iv e and flammable materials <br />near utilities. <br />Other Utilities <br />Would be negligible except for incidents impacting <br />rivers upstream from drinking water intakes for the <br />both communities. <br />Casualties <br />Would depend on location and identity of hazardous <br />(deaths and injuries) <br />material, time of day, and evacuation effectiveness. <br />Existing Hazard Mitigation Activities <br />The single most critical factor in enhancing both mitigation and emergency response <br />planning is specific inventory awareness of major hazardous materials sites within each <br />jurisdiction. Specific inventory awareness maintains detailed knowledge of the types <br />and locations of significant quantities of hazardous materials for every location in a <br />jurisdiction. What constitutes a significant quantity varies depending on the toxicity of <br />the material, dispersal characteristics, and the nature and population of the potential <br />affected areas. <br />The Office of State Fire Marshal (OSFM) conducts an annual Hazardous Substance <br />Information System Survey (HSIS) of Oregon facilities. The database created from the <br />survey contains the inventories of hazardous materials at fixed locations in the Eugene - <br />Springfield area. Transportation data of hazardous materials within or through the <br />Eugene -Springfield area and the HSIS data are the foundation for the specific inventory <br />awareness currently integrated into Eugene Springfield Fire Department. <br />Eugene and Springfield Fire has completed an Extremely Hazardous Substance (EHS) <br />pre -incident plans for all EHS sites, excluding towers due to their low level of risk. <br />Hazardous substance storage locations and transportation sites have been identified <br />detailing worst -case scenarios for risk. <br />6-151 January 2020 <br />
