Dear George:
This will confim my request to you on the telephone today that Babcock and Wilcox provide us with copics of the Site Problem Reports and.
Preliminary Safety Concerns listed below.
If it would be overly burdensome to provide photocopics of all of these documents, and if fiche is not a quick solution, I suggest that where files are quite thick the cover meno describing the PSC or SPR could be copied and sent to us; when we are down in Lynchburg conductir.g depositions, we can then review follow-up and other material for those files that appear to be most relevant.

These are drawings which were Deposition Exhibits 73 throur,h S4, inclusive.
(The drawing numbers are 136019 through 136027E, inclusive; 30755F; and 30765F, Rev. 4).
Also, Exhibit 71 to the Stevens Depositic i, a Standard Guide Spec., contains a drawing, of the control roca console layout (on page 4 of the spec) which makes it impossibic on our copy to make out names and numbers. Could we get a better or larger copy of this page?
'lhank you for your assistance.
S'incerely, C
