==Dear Mr. Parrish:==
By letter dated October 9, 2008, to the U.S. Nuclear Regulatory Commission (NRC), Energy Northwest submitted Inservice Inspection (lSI) Program Request 31SI-09 for Columbia Generating Station. The request was for NRC approval of the alternative to ASME Section XI, Subarticle IWB-2500, to allow reduced percentage requirements for nozzle to vessel weld and inner radius examinations for the 3rd ten-year interval lSI program. The NRC staff is reviewing your submittal and has determined that additional information is required to complete its review. The specific information requested is addressed in the enclosure to this letter. Please provide a response by December 19,2008, to this request for additional information.
 
The NRC staff considers that timely responses to requests for additional information help ensure sufficient time is available for staff review and contribute toward the NRC's goal of efficient and effective use of staff resources.
