By my letter to you dated December 15, 1977, you were requested to complete a
questionnaire to provide data for a study we are performing on the reliability
of standby diesel generators.

Due to a clerical oversight, parts 6 and 7 of item Q on page 18 were omitted
from the questionnaire sent to you.  Please utilize the enclosed page 17 (the
unchanged reverse side) and corrected page 18 in preparing your response.

We regret any inconvenience this may cause you.

                                    Sincerely,


                                    Karl R. Goller, Assistant Director
                                      for Operating Reactors
                                    Division of Operating Reactors
