SUBJECT:
SUSPENSION OF SALEM SALP
- i 1
In accordance with MC 0350, Region I recomends that the SALP process be i
suspended for the Salem facility until one year after the restart of the i
units. An assessment of licensee performance between the June 1995 shutdowns I and the restart will be developed to provide a basis for closure of the Confirmatory Action Letter and NRC agreement that the facility is ready to restart. Interim assessments will be developed in the form of Senior Management Neeting full discussion papers. During this time period, oversight l of the inspection planning and scheduling for the site will be done by the )
l Salem Assessment Panel which currently meets monthly.

- 1. PURPOSE i It is recognized that for both the safety and reassurance of the public of the Township of Lower Alloways Creek (LAC), a mechanism must be established for communication between Public Service Electric and Gas Company (PSE&G) and responsible officials of LAC regarding conditions or events at, or related, to the PSE&G facilities on Artificial Island. It l _ is also recognized that in the event of labor contingencies, ie. labor disputes, involving a potential threat to the public l
peace and good order, a plan must be in effect. The purpose of this Memorandum of Understanding (M.O.U.) is to set l forth those conditions, plans or events under which PSE&G will notify LAC, and the mechanics by which such ' notification will be carried out. De responsibilities of LAC are also determined in this M.O.U.
- 11. AGREEMENT l x s
~' ' The following terms have been agreed upon by PSE&G and LAC-l l
- 1. PSE&G will notify LAC by telephone with regard to each and every, condition or event listed in Enclosure (1) and in regard to any drill concemed in the time frame indicated. Notification will be by means of a dedicated telephone line to j the Township Municipal Building for Type 1 Events of Enclosure (1).
! 2. LAC will maintain rquipment and/or personnel in the Municipal Building at all times to record and transmit to responsible LAC Officials the message described in Paragraph (1)
- 3. LAC will not make public announcements or initiate contacts with the media on the sole basis of the messages described in Paragraph (1) except to prevent panic, injury to persons or damage to property.
- 4. PSEAG will keep available, on a 24-hour basis, an employee or a designated subtitute who will be able to notify and/or respond to inquires,from the LAC Officials listed in Enclosure (2) regarding conditions or events at or related to the j PSE&G facilities on Artifical Island. In the event that said employee is unable to respond immediatly to the inquiry, he or
- she will acek out the necessary information and respond to the inquiring official as soon as possible. PSE&G will provide l the names and telephone numbers of the foresaid ernployees 11
- Enclosure (3) to each of the LAC Officials listed in l Enclosure (2) or to their successors in office whose names shall be transmitted to PSE&G from time to time. l
- 5. This section 5 of the M.Q.U. sets forth guidelines for both parties in the event of a labor contingency involving a potential threat to the public peace and good order. ' Ibis Section shall become effective when it becomes necessary for l either party to take any action contained herein regarding a potentiallabor contingency as a foresaltl. This section of the M.O.U. shall remain in effect until such time as both parties agree that conditions are such that it need not be in force.

NOTIFICATION PSE&G agrees to notify. LAC of any potential labor contingency which affects the normal operations at Artifical Island as soon as PSE&O becomes aware of the problem. LAC agrees to notify PSE&O of any potential labor contingency which will affect the normal operations at Artificial Island as soon as LAC becomes aware of the proble'r% B. INJUNCTION HEARINGS PSE&G agrees to notify LAC of injunction meetings or hearings as soon as they are scheduled as a result of a labor contingency at Artificial Island. LAC agrees that it will endeavor to have those officials who are responsible for the policing of the labor contingency present at all injunction meetings or hearings. In the event that it is necessary, LAC agrees to furninsh testimony at any injunction hearing as to conditions at the strike line and the conduct of the pickets. Both parties agree that close coordination during the meetings or hearings be maintained to minimize the problems of l enforcing the terms of any injunction throughout the duration of the dispute, C. LIAISON 1 N ' I Whenever this section of the M.O.U. becomes effective the communication between PSE&G and LAC will be accomplished by the Government Relations Manager for PSE&G and the Chief of Police for LAC or their designees. l t Additional linea of communication may be arranged upon the concurrence of the Vic'e President - Nuclear and the Mayor of LAC. MEETINGS PSE&tl and LAC agree to schedule meetings to address problems during the term of the contingency. 'Ihe frequency of the meetings may increase or decrease as conditions warrant. E. PAYMENT OF EXPENSES Whenever it is deemed necessary 'bj the Chief of Police to enlist mutual aid assistance from other municipal police departments or forces to protect the public pense and good order during a labor contingency, the PSE&G Government Relations Manager'shall be so advised. PSE&G shall assume the responsibility for reimbursement to LAC for payment of all such reasonable and necessary mutual aid assistance provided during the term of the contingency. Reimbursement shall be in an amout equal to 100% of the expenditures for wages and food. Wages paid to mutual aid personnel will be one and one-half times each officer's basic hourly rate. In the even of a disagreement between the parties to this M.O.U. over the necessity for mutual aid, the question shallbe referred for resolution to the Salem County Prosecutor, wlmse response shall be determinative. LAC agrees to provide the Government Relations Manager with a daily report which shall set forth the number of mutual aid persbanel committed to the dispute. LAC further agrees to furnish a weekly report which shall set forth the names of all mutual aid personnel and the hours worked during that leriod. Upon termination of the contingency, LAC will submit an invoice to the Government Relations Manager for payment of said expenses within 60 days of receipt. If the need for mutual aid exceeds 30 days in duration, invoices will be submitted epr 30alays.
