Welcome to the Mitigation Monitoring Compliance and Reporting Program page for the East County (ECO) Substation Project in southeastern San Diego County, California.

Pursuant to the California Public Utilities Commission’s (CPUC) approval of the Project, San Diego Gas & Electric (SDG&E) is required to implement the Applicant Proposed Measures (APMs) and mitigation measures identified in the Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) and the Mitigation Monitoring, Reporting, and Compliance Program (MMRCP). The CPUC, as the lead agency, is responsible for ensuring that the APMs and mitigation measures, as well as plans reviewed and approved by other agencies, are implemented throughout the construction phase of the Project. Below are Project documents related to mitigation monitoring that are available for public review.

Mitigation Monitoring, Compliance and Reporting Program

The program’s goal is to ensure compliance with CPUC and Bureau of Land Management (BLM) adopted mitigation. The CPUC and BLM, in conjunction with SDG&E, drafted a Mitigation Monitoring Compliance and Reporting Program (MMCRP) to ensure compliance with mitigation measures approved in the Final EIR/EIS. A link to view a complete copy of the MMCRP is provided below.

MMCRP

Notices to Proceed (NTPs)

NTPs are issued contingent upon SDG&E’s compliance with pre-construction requirements as specified by the approved mitigation measures and responsible agency permitting requirements. A link to the approved pre-compliance reports, permit applications, and other documents is provided below.

CPUC - Minor Project Refinement Requests

The Commission decision approving the permit to construct authorizes Energy Division staff to approve requests by SDG&E for minor project refinements. The decision states that minor project refinements may be approved so long as such minor project refinements are located within the geographic boundary of the study area of the Environmental Impact Report/Environmental Impact Statement and do not, without mitigation, result in a new significant impact or a substantial increase in the severity of a previously identified significant impact based on the criteria used in the environmental document; conflict with any mitigation measure or applicable law or policy; or trigger an additional permit requirement. Below are SDG&E's Minor Project Refinement Requests that have been approved by the CPUC to date.

BLM - Variance Requests

As defined by the MMCRP, at various times throughout project construction, the need for workspace modifications or changes to the project requirements may be needed to facilitate construction or provide more effective protection of resources. The BLM will implement the variance procedures defined in the MMCRP to evaluate each proposed project variance for its potential for creating adverse environmental effects to determine whether supplemental NEPA review is required.

Variance Request Description Variance Request Submitted Variance Issued
001 Reroute a portion of the 138 kV underground transmission route and associated transition poles from BLM-managed land to private land. 7/5/13 7/12/13
