    NONSTRUCTURAL MEASURES FOR CONSIDERATION BY THE GLMRIS PROGRAM

    1 INTRODUCTION As part of the overall U.S. Army Corps of Engineers (USACE) Great Lakes Mississippi River Interbasin Study (GLMRIS) program and its objectives, a technology report was prepared that identified and evaluated technological approaches that may reduce the potential for the movement of aquatic nuisance species (ANS) between the Great Lakes and Mississippi River basins (GLMRIS 2012). This technology evaluation considered both engineering-based structural approaches (i.e., those that require the construction and operation of technology-based infrastructure) and nonstructural measures (i.e., those that do not require engineered construction for implementation and operation) for controlling interbasin transfer of ANS through the Chicago Area Waterways System (CAWS). The GLMRIS program also prepared a risk assessment report (Grippo et al. 2013) that evaluated the potential risks of ANS for undergoing successful interbasin transfer through the CAWS and causing unacceptable environmental, economic, and sociopolitical consequences. The risk assessmen
