Dear Ms. Carlock:
Enclosed are 3 CDs containing the models requested in IPUC Staf Requests 78, 79, 86, 87, 94,
and 95 in PAC-E-10-07. All the enclosed models are commercially sensitive and are classified
either "stadard confidential" or "higWy confdentiaL." "Stadard confidential" models are
grouped on one CD, while "higWy confdential" models are grouped on the other two. The
Company has long maintained a distinction between confidential and highly confidential
documents and canot adequately protect certain tyes of commercially sensitive information in
the absence of this distinction. Accordingly, should other paries in this proceeding request to
see the highly confdential analyses, the Company will follow its standard practice of making the
analyses available for review at the Company's offces or the offices oflegal counsel, with a
monitor present, but would not allow the paries to take the analyses or have them in their
possession except in the presence of a monitor. The Company can agree that Staff retan the
higWy confidential analyses, subject to standard confdentiality treatment, for a limited period of
90 days. The Company requests that at the end of 90 days, Staff retu the highly confdential
analyses to the Company without makng copies.
Sincerely,"r ,/'
