The California Environmental Quality Act (CEQA) requires state and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts, if feasible. When SMUD is designated as a "lead agency," meaning it is in charge of those projects, we are required to file CEQA reports and obtain public comments on the projects when available.
Below is information on current or planned SMUD projects requiring CEQA reports. Click on an item for more information pertaining to it. Large documents are best viewed using the Google Chrome browser.
Pocket/Greenhaven Underground Cable Reliability Project
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 installation of 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.

Colusa-Sutter Transmission Line Project
SMUD and the Western Area Power Administration (WAPA) have been working on the proposed Colusa-Sutter (CoSu) 500-kilovolt transmission line project since 2014, evaluating potentially significant environmental impacts to decide whether to proceed with final design and construction.The proposed 500-kilovolt transmission line would have connected the California–Oregon Transmission Project (COTP) to SMUD’s or WAPA’s transmission facilities on the west side of the Sacramento Valley.
The proposed CoSu 500-kilovolt transmission line project is canceled, effective immediately. Accordingly, the release of the Draft Environmental Impact Statement/Environmental Impact Report, planned for public release in mid-2019, is also canceled.
Station A Substation Rebuild and Relocation Project
The Sacramento Municipal Utility District (SMUD) is proposing to rebuild, reconfigure, and relocate portions of the Station A Substation at 6th and H Streets in the City of Sacramento. The proposed project includes installing new electrical equipment on a 1.3-acre site located directly to the north of the existing substation, relocating existing underground transmission and distribution lines, and decommissioning portions of the equipment located at the existing substation.
SMUD has owned and operated the historic Station A since the 1940s and constructed the outdoor portion of the substation in the 1950s. The existing substation equipment is nearing the end of useful life and requires replacement, upgrade and additional space to maintain Station A as a reliable power source for downtown Sacramento. Additional space is required because it would not be feasible to rebuild the existing substation in place while maintaining electrical service in the downtown area currently provided by Station A.
The project also includes relocation of a Regional Transit substation at the new site, construction of a new SMUD control building that will house electrical equipment replacing equipment currently located inside the existing Station A building, and new gas insulated substation equipment, and the construction of two small open space areas on 6th Street and 7th Street.
New Slab Creek Powerhouse and Boating Flow Release Valve Project
Sacramento Municipal Utility District (SMUD) has prepared a Draft Initial Study/Mitigated Negative Declaration (IS/MND) addressing the potential environmental effects of constructing and operating the New Slab Creek Powerhouse and Boating Flow Release Valve Project (Proposed Project), located in El Dorado County, California. The proposed project would require site preparation, construction of a connection to White Rock Tunnel, a new powerhouse, an electrical connection, and a boating flow release valve on the southern banks of the South Fork American River (SFAR). During operations, boating flows would be released from the new valve, rather than from spilling water over Slab Creek Dam. The proposed project also would include reconfiguring the mouth of Iowa Canyon Creek and completing habitat improvements along the SFAR (i.e., moving boulders in the riverbed to create a low flow channel in a ¼ mile stretch of SFAR immediately downstream from Slab Creek Dam and placing gravel into SFAR to enhance habitat for fish).
The New Slab Creek Powerhouse and Boating Flow Release Valve would be located adjacent to the SFAR in El Dorado County, California, approximately 50 miles east of Sacramento and 3 miles north of the town of Camino. The new powerhouse would be part of the Slab Creek/White Rock Development, which consists of Slab Creek Dam and Reservoir, Slab Creek Powerhouse (at the base of the dam), White Rock Tunnel and Penstock, and White Rock Powerhouse at the upper end of Chili Bar Reservoir.
