The presentation looks at the risks posed by hazardous materials in Oregon.
The purpose of this study is to (1) evaluate datasets that describe the storage, transport and accidental release of hazardous materials and (2) provide emergency planners a broad picture of locations, volumes and characteristics of hazardous material exposure

Hazardous material exposure associated with storage at a fixed facility or transport over highways, railroads, or waterways. Depends upon many factors  Relative danger of the substance Size of the release People  affected Environment impacted  • State Hazmat Team 12–LaGrande  responded to a motor vehicle accident with a spill of 300 gallons of chromic acid.  $500,000 estimated loss. • State Hazmat Team 08–Southern Oregon responded to a motor vehicle accident with a  spill of 150 gallons of diesel fuel.  $250,000 estimated loss. • State Hazmat Team 09–Tualatin Valley F&R  responded to an incident where 680 pounds of Refrigerant 507 leaked from a chiller line. From the Oregon State Fire Marshal  2009 Annual Report Purpose of study – Evaluate datasets that describe the storage, transport and accidental release of hazardous materials.  – Provide emergency planners a broad picture of locations,  volumes and characteristics of hazardous material exposure. Risk Framework Risk Transport Hwy, RR, Water Fixed Facility stored Fixed Facility spill Transport spill Fixed Facility • ERIS  unplanned release • HSIS Transport • ERIS unplanned release • Highway • Railway • Waterborne Key Datasets •ERIS  Emergency Response Information System •HSIS Hazardous Substance Information System UN Risk Classification System http://www.phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/Hazmat/Training/Chart%2014.pdf 6: Poison  7: Radioactive 8: Corrosive 9: Miscellaneous 1: Explosive 2: Gas 3: Flammable Liquid 5: Oxidizer and Organic Peroxide 4: Flammable Solid Highway Transport • ODOT provided one year of records of hazardous materials at 158 weigh stations for 12 months (March 2009 to April 2010) • Gross Weight in pounds • ODOT reported that 3.33% of  crashes involved hazardous materials in 2008. Highway Transport: Weigh Stations Highway Transport: Weigh Stations and Hazard Classes Highway Transport: Summer/Winter Highway Transport: Limitations • Data are associated with points rather than a network or routes • Impossible to assign direction and route of material across state • Portland Region weigh stations are outside of city limits • Washington highway data not available • Data is a sample of  weigh events when scales are open • Make pertinent data publically available Rail Transport • Two years of rail transport (2008-2009) for UP and BNSF were provided by ODOT  • BNSF averages approximately 19,000 trains and 155,000 loads of hazardous freight annually • UP averages approximately 33,000 trains and 120,000 loads of hazardous freight annually Rail Transport: Routes and Yards Rail Transport: HC 3 and HC9 Hazard Class 3 Hazard Class 9 Rail Transport: UP vs. BNSF Rail Transport: Limitations • Data were reported by commodity between segments  without origin/destination • Data were not reported by hazard class • Yards are shared; yard names are inconsistent • Data for minor railroads were not available   • Better than highway data!  Waterborne Transport • Five years (2004-2008 ) of data were downloaded from the US Army Corps of Engineers Navigation Data Center • Material listed by product groupings  • Columbia, Snake, Willamette River and Oregon Coast ports considered Waterborne Transport: Ports Waterborne Transport: Ports Waterborne Transport: Columbia River System Waterborne Transport: Limitations • Not linked to highway or rail data • No hazard class designation  • No records of hazardous material transported along the coastline     • Better than highway and railroad data!! • Approximately 19,000 facilities with stored hazardous chemicals   • Multiple chemicals at each facility resulting in a total of approximately 108,000 records • 81 attributes associated per record  Fixed Facility: HSIS Fixed Facility: HSIS Fixed Facility: HSIS by County & Class Fixed Facility: HSIS Volume by County Gas Liquid Fixed Facility: HSIS Limitations • Need correct and complete geocoding or lat/long • Audit / qualify the completeness of data • Not publicly available    • This is a very rich and comprehensive dataset for analysis ERIS Spills 2000-2009 Spills 8900 Valid Location 8560 Unique  6576 More than Zero  4399 Gallons 4200 Pounds 199 Blank Less than zero 267 Duplicate 1984 ERIS Spills 2000-2009 Gallons 4200 Fixed 1961 Oil 1238 Chemical 484 Other 259 Transport 2114 Oil 1931 Chemical 99 Other 84 Sewer 125 ERIS Spills 2000-2009 ERIS Spills 2000-2009 Number of Spills by Material ERIS Spills 2000-2009 State-Wide and UGB by Transit/Fixed ERIS Spills 2000-2009 ERIS Spills 2000-2009 ERIS Spills 2000-2009 ERIS Spills 2000-2009 ERIS: Limitations •Duplicate records made summaries difficult •For some attributes 30% of values are blank •Locations not provided for all events •Outliers skew data •“Other” used indiscriminately   ERIS Spills 2000-2009 Additional Analysis Compounding chemical exposure are overlays of additional risks including;  • Fire, flood, and tsunami events  • Patterns of high traffic volumes and trends of crashes • Vulnerable populations such as school and elderly care facilities  Future Directions    This is a first attempt at determining broad patterns of risk of exposure to hazardous materials  This information will be provided to emergency responders and planners  There are many more research questions to ask Response and Planning Local Emergency Planning Committees (LEPC) Study Funded by the Office of State Fire Marshal        In partnership with the Oregon Department of Environmental Quality Don Pettit- Senior Emergency Response Planner and Steven Jett- GIS Analyst Extraordinaire  And in collaboration with fellow CSAR associate,  Christopher Rowlette  during the IRIS Project
