ATTACHMENT A SoCalGas Request for Confidentiality on the following information in its response to AL 5292 Attachment A Location of Protected Information Legal Citations Narrative Justification ltems Highlighted in grey in AL 5292 Attachment A CPRA Exemption, Gov‘t Code 6254(k) ('‘Records, the disclosure of which is exempted or prohibited pursuant to federal or state law”) Civil Code l798.80 el seq. (process for protecting customer records) Civil Code 1798.98 (protecting energy usage data) Evid. Code 1060 Civil Code 3426 etseq. CPRA Exemption, Gov't Code 6254,7(d) CPRA Exemption, Go\/t Code 6255(a) (Balancing Test) Cal. Pub. Util. Code 8380(d) (a utility “shall use reasonable security procedures and practices to protect a customer's electrical or gas consumption data from unauthorized access, destruction, use, modification, or disclosure”) and associated CPUC Decisions (D.1 1-07~0S6 and D. 12-08-045). Findings of Fact 23 and 27, D.l2« 08-045 Section 8380 of the Pub. Util. Code makes privacy protections for the usage data generated by AMI a basic consumer protection that both electrical and gas corporations must provide. 27. When curtailments are called, information regarding affected customers should be limited to a geographical area. Information regarding an individual customer's rate or gas reductions could influence competition in the gas market, signal customers about product continuity, and violate a customer’s privacy. Data is market-sensitive information that, if revealed, would place customers at an unfair business disadvantage because it provides market sensitive information regarding customer usage data. Private customer data related to energy usage and its implications and savings. Public disclosure of this information could compromise privacy to the potential harm of customers. For example, the detailed hourly energy use at a home could reveal if a customer is away from their home for long periods of time exposing them to home invasion robberies or other criminal acts. Customer equipment, processes, and operations provide competitive advantages in certain industries and

Since there are no obstacles that would prevent the extension of the privacy rules, and since such an extension is consistent with the provisions of Section 8380 of the Pub. Ulil. Code, it is reasonable to extend the piivacy rules adopted in Dill-O7-056(a.t1d contained in Attachment A herein) to gas corporations”) can be considered trade secrets. Allowing information detailing such information could cause financial harm to customers.
