SMUD is proposing to develop a new substation in Sacramento on a 10.3-acre site at 1220 North B Street in a developed area of downtown Sacramento. The project would consist of demolition of existing on-site structures and construction on new infrastructure to support up to five 40 MVA (megavolt amperes) 115/21kV transformers for a total of up to 200 MVA.

Substations are critical links in the electrical distribution system. Electricity travels through SMUD’s transmission system to substations where it can be converted to a lower voltage before safely being delivered to homes and businesses. The Station J Substation would directly serve the midtown and downtown areas, improving energy reliability and capacity.

SMUD is proposing the construction and operation of a new substation and decommissioning and removal of outdated equipment at the existing Elverta Substation. The proposed El Rio Substation would include new transformers and circuit breakers, a control building, paved access, fencing, lighting, stormwater drainage, stormwater retention basin, and utilities. North of the substation, two existing electrical towers carrying 230-kilovolt (kV) transmission lines would be replaced with two or three steel monopoles (also known as steel tubular poles) to tie the substation into the existing grid. Following the energization of the proposed El Rio Substation, the existing Elverta Substation would be decommissioned, and the outdated substation equipment dismantled and removed from the site. Project construction is anticipated to begin during the first quarter of 2025 and would be completed by late 2026, involving active construction for approximately 24 months, and 3 months to decommission the Elverta Substation.

SMUD is the lead agency responsible for complying with the provisions of California Environmental Quality Act (CEQA). A draft initial study/mitigated negative declaration has been prepared by SMUD to evaluate potential environmental effects resulting from the El Rio Substation Construction Project (project). The document has been prepared in accordance with the CEQA (Public Resources Code [PRC] Section 21000 et seq.) and the State CEQA Guidelines (CCR Section 15000 et seq.).

SMUD proposes to install a full-scale soil vapor extraction (SVE) system to remediate volatile organic compound (VOC)-impacted soil gas as well as excavate and dispose soil contaminated with arsenic. In order to access the contamination, multiple buildings would require demolition. The “59^th Street Demolition and Remediation Project” or “project” would include building demolition, installation and operation of the SVE system, and excavation and disposal of contaminated soil. All remediation activities would be reviewed and, prior to implementation, must be approved by the California Department of Toxic Substances Control (DTSC) to ensure protection of human health and the environment. SMUD proposes to remediate the site to appropriate risk and exposure levels as determined by DTSC.

The Draft IS/MND analyzes the potential environmental effects associated with the proposed Project in accordance with the California Environmental Quality Act (CEQA). In accordance with Section 15072 of the CEQA Guidelines, SMUD has prepared this Notice of Intent (NOI) to provide responsible agencies and other interested parties with notice of the availability of the Draft IS/MND and to solicit comments and concerns regarding environmental issues associated with the proposed Project.

SMUD has prepared a Operations, Maintenance, and New Construction Habitat Conservation Plan (HCP) to support issuance of requested Incidental Take Permits (ITPs) from the California Department of Fish and Wildlife (CDFW) and U.S. Fish and Wildlife Service (USFWS). The HCP is a 30-year plan designed to avoid, minimize and mitigate impacts to HCP Covered Species that may be affected by SMUD’s various operation, maintenance and new construction activities. The HCP covers activities within SMUD’s service territory and in portions of Placer, Yolo, Amador and San Joaquin counties where SMUD’s facilities are present. The HCP Covered Species includes 7 state and federally endangered and threatened species — slender Orcutt grass, Sacramento Orcutt grass, vernal pool fairy shrimp, vernal pool tadpole shrimp, valley elderberry longhorn beetle, vernal pool tadpole shrimp, California tiger salamander and giant garter snake.

The Draft Environmental Impact Report (EIR) evaluates the potential impacts of issuance of the ITPs by USFWS and CDFW, implementation of those ITPs and approval and implementation of the proposed HCP (proposed Project). SMUD prepared the EIR to satisfy the requirements of the California Environmental Quality Act (CEQA) (Public Resources Code [PRC] Section 21000 et seq.) and serves as the lead agency for CEQA compliance. The purpose of the EIR is to inform agency decision makers and the public regarding the anticipated significant environmental impacts of the proposed Project, potential measures to mitigate these significant impacts and reasonable alternatives that could reduce the significant environmental impacts of the proposed Project to a less-than-significant level. The EIR will be used by SMUD to comply with CEQA.

The project involves the replacement of approximately 2 miles of existing underground 69kV cable within existing right-of-way and construction of up to 15 new manholes along the route to allow for improved access and maintenance of the power line. From the eastern terminus of the project alignment, the existing 69kV cable extends westward beneath I-5, as presented in Exhibit 1. It is unknown whether the cable beneath I-5 is encased in conduit or directly buried in the ground. If the cable is within conduit, it will be replaced by pulling through the conduit. If the existing cable is direct-buried, the project would include installing conduit and new cable beneath I-5, or overhead lines crossing I-5. After crossing I-5, the alignment runs northwest through an existing apartment complex parking lot to the northeast corner of the existing Nugget supermarket, along Florin Road just west of I-5.

The Draft IS/MND analyzes the potential environmental effects associated with the proposed Project in accordance with the California Environmental Quality Act (CEQA). In accordance with Section 15072 of the CEQA Guidelines, SMUD has prepared this Notice of Intent (NOI) to provide responsible agencies and other interested parties with notice of the availability of the Draft IS/MND and to solicit comments and concerns regarding environmental issues associated with the proposed Project.
