<br />Section 4 <br />4-44 Ramsey County Multijurisdictional Hazard Mitigation Plan | July 2012 <br />Ramsey County is also at risk to transportation related hazardous materials incidents. This is directly <br />attributable to the presence of multiple highways (Interstate 35E, 35W, 94, 494, 694; U.S. Hwy 10, 52, <br />61;, MN Hwy 5, 13, 36, 51, 96, 120, 149, 156, 280) running through portions of the County as well as the <br />several railroads that carry materials through the County. <br />Vulnerability Assessment <br />Ramsey County averages approximately 90 hazardous materials spill occurring in any given year. <br />Assets Exposed to Hazard <br /> Property Risk/Vulnerability: With multiple highway system, all critical facilities have the <br />possibility of being affected by a hazardous materials incident. <br /> People Risk/Vulnerability: In evaluating vulnerability of the population in Ramsey County, it was <br />determined that risk/vulnerability includes the entire population of the County since there is no way <br />to determine the impact/magnitude of a hazardous materials incident and no way to predict where <br />and when a hazardous materials incident will occur. People are vulnerable to hazardous materials <br />incidents through effects on transportation routes, establishment of shelters, etc. <br /> Environment Risk/Vulnerability: Risks to the environment are high should a hazardous materials <br />accident occur. Environmental concerns would be interruption of water supply and secondary events <br />such as fires and hazardous materials accidents (such as gas pipelines rupturing, rupture of hazardous <br />material containers at facilities, etc.). When spills do occur, whether inside or outside facilities or <br />along roadways, shutdowns, lost time, and expended man-hours are all factors mitigation planners <br />must take into account. <br />Damage Assessment <br />It is difficult to determine the damage to the environment associated with hazardous materials spills. <br />Ramsey County has no recorded instances of critical facilities and/or other property being damaged as a <br />result of hazardous materials spills. <br />Land Use and Development Trends <br />Ramsey County currently has no land use or development trends related to hazardous materials spills.
