Environmental Issues Discussion Attachments

  • Technical sub-group- International Joint Commission- 5- June 14, 2012. Graphs showing coastal impacts for Lake Ontario by county for first floor flooding, erosion damages and shore protection maintenance costs comparing Plans 58DD, Bv7 and E (unregulated)
  • Austin, John C.; Anderson, Soren; Courant, Paul N.; Litan, Robert E.- Brookings Institution- Sept 2007. This report summarizes the major findings of a more in-depth study—Developing America’s North Coast: A Benefit Cost Analysis of a Great Lakes Infrastructure Program—of the benefits and costs of the federal-state Great Lakes Regional Collaboration (GLRC) Strategy by the same authors. It begins by outlining the major elements of the restoration strategy, and the costs of cleaning and preserving the Great Lakes ecosystem. It then describes the results of a rigorous analysis of the GLRC Strategy, highlighting the economic benefits of its implementation. The report concludes by discussing the policy implications of this analysis, arguing that, because the restoration plan outlined in the GLRC Strategy is likely to produce economic benefits well in excess of its costs, federal and state policy makers should act on its recommendations.

Other Issues of Importance Attachments

  • A note regarding the cost of shore protection in the FEPS model used to evaluate regulation plans in the LOSLR study

Recreational Boating Discussion Attachments

  • Technical sub-group- Internatinal Joint Commission- 1- Jan 2012. Graph showing average Lake Ontario water levels under the historic 101 year water supply sequence for the current plan 1958DD, Plan Bv7 and unregulated levels.
  • Technical sub-group- International Joint Commssion- 37 pages- June 11 2012. Graphs and tables that show a comparison of Plan 58DD and Bv7 relative to the preferred boating range based on the economic analysis conducted for recreational boaters, charter boat and marina operators and yacht clubs during the Lake Ontario-St. Lawrence River Study.
  • Nancy A. Connelly, Jean-Francois Bibeault, Jonathan Brown, and Tommy L. Brown- Lake Ontario St. Lawrence River Water Level Study- HDRU Series No. 05-1- Mar 2005. The International Joint Commission established the International Lake Ontario –St. Lawrence River Study Board in 2000 and commissioned them to undertake a comprehensive five-year study to assess and evaluate the current criteria used to regulate outflows from Lake Ontario through the St. Lawrence River. The Study Board created technical work groups charged with gathering scientific data on different interests affected by water levels on Lake Ontario and the St. Lawrence River.
