b) No electric utility generation function employee shall have access to or receive any information described in subsection (a) unless verifiably authorized to do so by the non-affiliated ARES, other electric utility, customer of non-affiliated ARES or other electric utility, or retail customer, or unless required by tariff or by regulatory or judicial order.

c) If any information described in subsection (a) is accessible to or received by a generation function employee of the electric utility in violation of subsection (b), the electric utility shall notify the non-affiliated ARES, other electric utility, customers of non-affiliated ARES or other utility, or retail customer, whose data or information was disclosed, and the Commission's Energy Division Manager or his/her delegate, within 24 hours. The electric utility shall keep a log of all such instances. The log and entries in the log shall be kept confidential unless the Commission, after notice and hearing, determines that the data or information is not entitled to confidentiality. Entries in the log shall be retained for three years. The Commission or the electric utility shall inform the public, upon request, of the number of entries in the log.
