We initially transmitted our responses to youunder our serialized letter 56001-006 dated November 11, 2005. Unfortunately, the responsesattached to letter 56001-006 were not complete. Please discard them and replce them with thoseattached to this letter.We suggest we hold a Comment resolution Conference in the near future to discuss and developa mutual understanding of the modifications we will make to the Rev 0 planning documents.Because of leave time scheduled by BCS project staff, we suggest meeting either during theweek of December 5, 2005, or after January 2, 2006. We look forward to meeting with you todiscuss our responses.If you have questions or wish to discuss our responses, please call me at (907) 743-9322.Sincerely,Bristol Construction Services, LLC>~-{;,[ji~~C;'i!i~~Steven A.
