DATE: April 6, 1990 RE: Accountability During Emergencies O

V Log: NOV-00426 Exhibit ,page of FROM: G. Bockhold, Jr.

TO: All Emergency Directors and Site Personnel In the event of site emergency conditions, we will implement the following revised procedures. These changes will enhance personnel accountability and safe'ty and ensure better information flow for employees. They will also provide flexibility to the plant when responding to emergency situations.

When the Emergency Director (ED) makes an emergency classification, he will make the appropriate tone and page announcement on the plant PA system. He will direct site personnel to the appropriate locations.

If you can not hear the page, report to your supervisor. He or she will direct you appropriately. Normally non-essential personnel will report to the Admin. Building auditorium or parking lot. David Phillips, the Financial Services Supervisor, has authority to coordinate with the ED and control the disposition of non-essential personnel.

In his absence, the senior person present will contact the Security Captain for additional assistance.

Emergency Response Organization (ERO) personnel should report immediately to the appropriate facility. Other shift personnel, supervisors, and managers on-site should report initially to the f]

(, OSC. Overflow personnel will assemble in the maintenance machine shop area.

When directed by the ED, the security department will initiate accountability. The security department cannot account for personnel who fail to log into the appropriate ERF (e.g., control roce. TSC, or OSC) so it is essential we comply with the ED's instructions as soon as possible.

Your assistance implementing these instructions will ensure we manage emergencies better and provide plant personnel with sufficient information to keep them infomed of abnormal plant activities.

Thank you for your assistance.
