b.
The licensee has receive'd and reviewed IEBs through IEB 80-02 at the site. The project manager and construction engineer review all IEBs for site applicability and coordinate a response if needed with cor-porate design and licensing personnel. The following IEB's are not applicable to the site or require no action (issued for information only):
.
IEB 79-24 IEB 80-01 IEB 79-26 IEB 80-02 IEB 79-27 The bulletins listed above are closed.
