Dear Mr. Keppler:

Coc:monwealth Edison notified your office on May 8, 1979 of a possible deficiency in the steel ventilation stack at LaSalle County Station. That notification was made in accordance with 10 CFR 50.55 (e) . This letter fulfills the 30-day reporting requirement impos M by that regulation.

As was reported, defects identified in the bottcsa ring of the stack led to the comprehensive non-destructive examination of the affected areas of the stack. A stmaury of the results of the inspection conducted is provided as an attachment to this letter.

Although it has been determined that no i::nnediate remedial. action is required, the permanent repair or re-enforcement of the vent stack is now being studied. It is expected that a final report on this deficiency can be provided by October 1, 1979 at which time sufficient evaluation of alternative modification schemes will have been ccznpleted, s

Please address any questions on this suhaittal to this office.
