NAVIGATION SEASON EXTENSION DEMONSTRATION PROGRAM, 1979: FINAL ENVIRONMENTAL STATEMENT

The purpose of the Demonstration Program is to determine the practicability of various methods for maintaining an extended navigation season on the Great Lakes-St. Lawrence Seaway System, and to obtain baseline data needed to determine the engineering practicability and environmental acceptability of an extended season. The Demonstration Program is therefore designed to: (a) Monitor, observe, analyze, predict, and disseminate ice data to the various user groups and program elements in the Great Lakes-St. Lawrence Seaway System. (b) Demonstrate practicability of overall safe and efficient movement of vessels through ice covered waters. (c) Assess and advance the state of the art in ice mechanics and engineering, develop adequate instrumentation and measurement techniques, and develop design criteria for structures to withstand ice forces. (d) Determine practicability of winter navigation in the International Section of the St. Lawrence River without adverse effects to other interests; locate methods to slow down the formation and to speed up the deterioration of ice in specific locations in the river. (e) Develop and implement tehcniques, operating procedures and ice control devices for effective and efficient ship operation. (f) Define items having economic feasibility for winter navigation by determining costs, benefits, and cost effectiveness of relevant projects and progress within the scope of the program. (g) Analyze environmental effects of specific demonstration projects for areas where projects involve physical contact or interaction with the immediate environment but have application for the entire Great Lakes system. (h) And to identify significant social effects of winter navigation, and to identify solutions or further investigations.
