Subject:
Maine Yankee Emergency Plan
Dear Sir:
A revised upgraded Maine Yankee Emergency Plan (enclosed) is hereby sub-mitted in accordance with the commitment made via Reference (f).
Development of the upgraded emergency plan has been underway for some time now in anticipation of promulgation of a revised rule on emergency plans, and has proceeded with cognizance of the progress made in devel-oping the revised rule.
This revision represents another step in the continuing evolution of the upgraded plan.
It also takes into account the thirty-six pages of detailed comments transmitted via Reference (g) which were generated during the thorough review of the previous revision performed by your staff and dis-cussed in the highly productive review meeting held at the Maine Yankee site during the week of June 1.
Several aspects of the upgraded plan require further development, refine-ment, or clarification.
Our intent is to continue development and inte-gration with the developing upgraded plans of state and local governments, and to develop and put into effect upgraded emergency plan implementing procedures as early as practicable, both without undue concern or hesi-tation with res eet to the progress made in promulgating and making the final rule effe,
.ve.
Those aspects requiring significant additional effort are discussed below.

MAINE YAbKEE A'TOMIC POWER COMPANY PAGE United States Nuclear Regulatory Cc==ission Attention: Office of Nuclear Reactor Regulation July 31, 1980 Public E=ereencv Alert Syste= (PEAS)
A public e=ergency alert syste= concept has been developed which is acceptable to and supported by the Maine Bureau of Civil E=ergency Preparedness and the Governor as well as Maine Yankee.
The concept involves three overlapping ele =ents 1) re=otely controlled fixed sirens covering an area within about five =iles of the plant and in addition, the Boothbay Harbor pen-insula which is felt to be unique in ter=s of evacuation
- 2) =obile sirens and public address syste=s installed in vehicles used by notifier tea =s in the areas identified in local govern-ment plans together with an aree wide paging syste= and pagers assigned to local officials and notifier tea =s to allow rapid
=obilization, each covering the entire plu=e exposure planning zone, and 3) a NOAA weather radio trans=itter, with tone alert and e=ergency condition and followup =essage capability to be installed in the
'41scasset area.
This will ensure clear, strong signals and reception by lcw cost in-ho=e tone alert / weather =enitors through-out the area for anyone who desires to purchase a =cnitor.
The entire plu=e exposure planning zone (which ext.nds well beyond the 10 mile standard in so=e directions) is covered by the =obile siren /pager syste= and the NOAA trans=1tter signal. The fixed siren syste= provides pri=ary coverage for area within about five =iles of the site and for special areas.
There are two =ajor objectives in the PEAS program. First, the design perfor=ance require =ents relating to efficiency of warning =ust be =et.
Also very i=portant is the necessity of offsetting the burdens i= posed upon local co== unities through new e=ergency planning require =ents and plan develop =ent by ensuring that the PEAS provides benefits to the affected co== unities on a continuing basis (of necessity, in circu= stances other than nuclear power plant e=ergencies).
In prac-tical ter=s, enhance =ent of non-nuclear related e=ergency protection e.g. fire, police, a bulance, stor= warnings, provides an incentive for the twenty co== unities involved to converge to a workable and desirable regional syste=.
The steps necessary to proceed further in developing and i=ple=enting this concept involve reaching agree =ent on the syste= concept and details of equip =ent location, usage, installation, =aintenance,etc.,

PAGE United States Nuclear Regulatory Commission Attention: Office of Nuclear Reactor Regulation July 31, 1980 with each of the twenty local governments involved, obtaining necessary regulatory approvals, then specification, procurement, installation, checkout, and acceptance of all necessary equipment. We are proceeding as best we can in this area.
Offsite Dose Proiections The current plan revision describes a method for estimating offsite doses utilizing nomograms which relate source and meteorological information to offsite dose rates.
We are currently investigating the feasibility of computerizing the offsite dose projection to relieve emergency response personnel from the data manipulation involved.
In the event it is in fact feasible to computerize the dose projection process, using real time data, the nomograms now indicated in the plan to be : he primary method would be relegated to a backup method.
Protective Action Recommendations Maine Yankee intends to further develop their capability to make recommendations on offsite protective actions to offsite authorities and to factor into these recommendations conditions which exist in the planning zone at the time where practical.
We are working with the Maine Bureau of Civil Emergency Preparedness and the Maine Division of Health Engineering in this area.
Emergency Action Levels We have noted numerous approaches to delineation of EAL's and assoc-iation of initiating events with EAL's.
Most are lengthy, detailed, complex and therefore have a high potential to be confusing, difficult to keep current, and difficult to integrate with operating and admin-istrative procedures.
Maine Yankee is striving to reconcile the requirements concerning EAL's with our existing procedural and diagnostic systems.
Our understanding is that the new rule on emergency planning in part 50.47(b)4 requires "A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters..."
We will continue to develop Table 4-1 of the current draft plan to meet this requirement and provide the appropriate level of detail.
MAINE YANKEE ATOMIC PC4VER COMPANY United States Nuclear Regulatory Commission Attention:
Office of Nuclear Reactor Regulation July 31, 1980 This letter and the enclosed revised draft represent the current status of upgraded emergency plans for Maine Yankee.
Additional information will be submitted from time to ti=e as it becomes available.
In the meantime, the current approved emergency plan and implementing procedures (of Maine Yankee as well as of state and local governments) remain in effect.
If there are any questions, please do not hesitace to call.
