In the initial permitting timetable, Commission staff included a project sponsor dependency stating that the Commission’s “milestone target dates . . . are dependent on the project sponsor resolving all application deficiencies, additional information needs, and required studies by July 10, 2023.”  However, after the permitting timetable was published, the project sponsor agreed to conduct additional studies requested by the Bureau of Land Management and other agencies and proposed to file the study results by “November 2023,” and Commission staff issued a letter requiring the corresponding study reports and additional information to be filed with the Commission by November 30, 2023.  The Commission’s milestone target dates are being modified to account for the additional time needed for the project sponsor to complete the studies and file the additional information.
