On Itay 18, 1982 we had an extensive meeting with the Uf:P-2 applicant to resolve open issues with special emphasis on the Southeastn a tiCline fault.

This aspect of the review is progressing well and the applicant's new investigations have concluded that it is not capable. Their repcrt is expected on June 4, 1932.

The USGS attended this review meeting and discussed with us the interpretation of seismic reflection profiles currently under review for Skagit/Hanford site. They pointed out locations of faults in deeper horizons within 5 miles of the W!iP-2 site. This data was collected for the waste repository work and is generally not suitable to demonstrate continuity of units closer to the surface, i.e. to demonstrate non-capability. Uc have been aware of such faults at depth and have been. attempting to. handle this data completely under the Skagit/Hanford review and we have approached it as a confimatory item with the understanding that further work from the Skagit applicant may be needed to resolve any possible " suspect" areas where other data is insufficient to reach resolution.

The USGS. indicated, however, that they may indicate the presence of these

" unresolved" faults in their letter on ut:P-2. at the present time I do not know of any action we can take except to continue our discussion with the USGS. Uc will have to address this issue upon receipt of the USGS letter.

This could have an inpact on our SER input completion.
