6.4.1 Completed Projects

There are two Tracking Numbers that were reported in the 2007 Biennial Report in the West Central Zone that have been addressed. Information about each of the completed projects is summarized briefly in the table below, and those matters will be removed from the list of inadequacies that are discussed in the 2009 Report. More detailed information about these projects and inadequacies can be found in the 2005 and 2007 Reports and in the PUC Docket for the matter if the project fell within the jurisdiction of the Public Utilities Commission, in which case the Docket Number is shown below. Also, additional information is available by contacting the designated person for the utility that was responsible for constructing the project.
