ITEM III. A.2 IMPROVING LICENSEE DER-GENCY PREPAREDNESS - LONG TEPJ4 Consumers Power Company submittal dated December 19, 1980 provided our then current positions on items in NUREG-0737 dated October 31, 1980, entitled
" Clarification of T'4I Action Plan Requirements". Our response to Item III.2.A of NUREG-0737 indicated our intent to provide complete interim meteorological capability as defined by NUEEG-0737 by April 1,1981.
The results of the Big Rock Point Probabilistic Bish Assessment indicate no need for immediate warning of the public vithin the EPZ for any postulated accident.
The meteorological program proposed in Attachment 1 amply provides the infor-mation necessary to determine the appropriate protective actions for the public.
This meteorological program provides National Weather Service data through an This automated computer system maintained by Weather Services International.
meteorological capability including plant procedures revision and personnel training vill be provided by April 1, 1981. Therefore, it is Consumers Power Company's position that additional meteorological capability beyond those Information relating to this concit sion vill proposed herein are unnecessary.
be provided in the near future with submittal of the Big Rock Point Probabilistic Risk Assessment.
Consumers Power Company is currently investigating supplemental meteorological capabilities which might be necessary for ingress and egress of personnel involved in necessary recovery and cleenup activities resulting from postulated accidents.
These investigations and their resulting modifications, if any will be evaluated on the basic of ALARA.

ATTACH E T 1 Big Rock Point Plant Meteorological Capability Consumers Power Co=pany has completed the Big Rock Point Probabilistic Risk P
Assessment (PRA). The FRA results indicate no need for immediate warning of the public within the EPZ for any postulated accident. Nevertheless, the Charlevoix County Emergency Plan identifies eighty-six (86) residences and two (2) industrial establishments within two miles of the plant, all of which will be notified of e=ergencies and be requested to take emergency actions based on the alternative meteorological data described below. Therefore, specific conformance with the NUREG-0737 position associated with ceteorolo-gical capability is unnecessary.
Arrangements have been made to provide meteorological information by eccessing National Weather Service (NWS) data through an automated cceputer system tain-tained by Weather Services International (WSI). This information vill te used to determine the appropriate protective actions for the public in the event of any postulated accident. Access to this system is accomplished by use of a dial-up remote terminal at the plant site.
The reliability of the system is assured through the use of redundant computers and multiple telephone access ports. Table 1 contains examples of display formats for the NWS data. The data recorded at Pellston (PLN) and Traverse City (TVC) Michigan vill be used as the primary data sources. Procedures have been established which allow the calculation of Pasquill stability categories from the NWS data.
In addition to providing most recent and historic vcather data as displayed in Table 1, WSI will provide a display of the NWS recent forecast for the Big Rock Plant area; Figurea 1 and 2.
The forecast will be printed on the remote terminal upon request, WSI forecasters also are available for providing meteorological data interpretation and evaluation on a 2h-hour basis. In the event this system becomes inoperable, plant emergency procedures provide an alternate source of meteorological information by calling the National Weather Service at Sault Ste. Marie and Ann Arbor, Michigan. These information sources are available on a 2k-hour basis and provide current meteorological information as well as long range detailed forecasts.
The meteorological program, as presented above and the notificatien of the 68 residences within 2 miles of the plant on a 2L-hour basis provide adequate compensating actions for Big Rock Point in accordance with 10CFR 50.L7(c)(1).
This program is adequate in view of the FRA findings for the protection of the public for both the present and future.
