Dear Mr. Baca:

In conformance with my discussion with Mr. Cubia Clayton of your staff en flovember 8,1979, I have enclosed the up-ta-date letter reports by cur consultants on the safety review of the proposed addition to the northern embankment and cross dikes of the Church Rock tailings impound-ment.

These reports are not a final evaluation but they identify what con-clusions can be made now and include a compilation of outstanding issues to be resolved before a final stability determination can be made.

Please note that our safety evaluation did not include an independent assessment of the geological, seismological and hydrological considerations covered in Regulatory Guide 3.11.

As requested by Mr. Clayton, this report marks the termination of our technical assistance related to the stability evaluation of the existing Church Rock embankment.

Sincerely, l

.f" Ross A. Scarano, Chief Uranium Recovery Licensing Branch Division of Waste Management
