. Honorable Nunzio J. Palladino March 17, 1986 that took place in this ama. The NRC Staff has engaged the services of U$65 to evaluate these hypotheses to see if there really may be a causal connection. and, if so, whether there is any likelihood of substantially larger earthquakes in the future. The NRC Staff will keep the ACR$

informed as to the progress of the USGS work.

One of the ACR5 consultants suggested that monitoring with sensitive seismological instruments over the next few years would be helpful in assessing the possible causal connection between the deep well injection and the January 31, 1986 earthquake. The USGS representatives attending our discussions agreed that such seismic monitoring would be valuable.

Therefore, unless the USGS and the NRC are able to decide that there is no causal connection or that earthquakes of a magnitude sufficient to be of concern can be ruled out from this cause, we recossend that The Cleveland Electric Illuminating Congany assure that appropriately sensitive monitoring be continued over the next few years.

We agree with the NRC Staff that the January 31, 1986 earthquake is unlikely to lead to any requirements that would significantly change the.

design of the Perry plant's structure or its equlpment. Based on the infonnation developed in these meetings and considering the above coments, we find no reason to alter the conclusions stated in the Comittee's report dated July 13, 1982 regarding operation of this nuclear plant.
