  3. WHAT IS THIS PROJECT ABOUT… Determine where selected NOHM may intersect ODOT operations Assure that ODOT maintenance and construction activities take the presence of the selected NOHM into account Develop GIS datasets that inform ODOT personnel of the hazard characteristics of the selected NOHM ODOT Geo-Hydro-HazMat Technical Presentation, September, 2009 Clark Niewendorp
