SDG&E sought protection for Appendix D of the Draft Environmental Assessment. Appendix D contains detailed information containing the location and contents of historic and prehistoric sites within the project area. The protection request is consistent with that required of Native American graves, cemeteries, and sacred places under Government Code § 6254(r) and we will approve the requested protection. Unlike most information for which protection is sought, the information included in Appendix D will continue to remain sensitive over time. Therefore we will retain the material under seal in perpetuity without requiring SDG&E to renew its request for protection.
