n. Procedural Schedule: On September 30, 2009, Seattle City Light filed an agreement-in-principle and a request to suspend processing of the license application until February 1, 2010 to complete settlement negotiations. The negotiations also involve measures linking the Boundary relicense with the surrender of Pend Oreille County Public Utility District's Sullivan Creek Project No. 2225. In the interest of furthering settlement negotiations and resolution of both proceedings, we are agreeing to delay the issuance of our ready for environmental analysis notice. Therefore, the application will be processed according to the following Hydro Licensing Schedule. Revisions to the schedule may be made as appropriate and a more detailed schedule will be issued with the ready for environmental analysis notice.
