Objective: |
Two surveys of shippers and carriers affected by the Lock 27 closures in 2004 and 2005 were conducted for the purpose of discerning total costs incurred and operational changes made by industry associated with each closure event.. The survey for the 2004 closure was conducted between 25 February and 28 March 2005. The survey for the 2005 closure was conducted between 14 April and 12 May 2006. In addition to the industry surveys, an analysis of the OMNI data for Lock 27 was be conducted by the St. Louis and Rock Island districts for each closure. The analysis examined the detailed OMNI data for the Lock 27 facility, particularly for the closure periods, to identify changes in operating procedures attributable to the closure and to draw comparisons with the industry survey responses. Separate closure event reports were compiled for the 2004 and 2005 closures of Lock 27. |
