Agenda Item 5 Attachment A Errata CEQA Initial Study/Mitigated Negative Declaration PG&E Transmission Pipeline L-114 Replacement Project This errata document is prepared for the PG&E Transmission Pipeline L-114 Replacement Project Initial Study/Mitigated Negative Declaration (IS/MND). It lists sections of the IS/MND that are the subject of minor revisions or modifications since the release of the document for public review. None of the modifications noted below result in a “substantial revision” requiring recirculation. Rather, these errata provide clarifying information, as specified in §15073.5 of the CEQA Guidelines, to an adequate IS/MND. Further, these minor revisions or modifications to the IS/MND do not substantially change the setting, impacts, or mitigation measures identified. In addition to the listed revisions, please note for clarification that IS/MND references to the “project proponent” or “project applicant” both refer to PG&E and that this errata document does not propose revisions with respect to these references.
