The California Environmental Quality Act or "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.
The Western Area Power Administration (Western) and Sacramento Municipal Utility District (SMUD) are studying environmental impacts of a new 500-kilovolt electric transmission line project in portions of Colusa and Sutter counties to help meet Northern California's energy needs. The Colusa-Sutter Transmission Line, or CoSu Line, would provide SMUD with a new connection to the existing California-Oregon Transmission Project (COTP) line in Colusa County by linking it to a new substation near the existing O'Banion Substation in neighboring Sutter County, with potential modifications to SMUD's existing Elverta Substation in Sacramento County.
For the most recent information and for announcements, please visit the Project website at: www.CoSuLine.com.
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.
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.
Sacramento Municipal Utility District (SMUD) has prepared a Final Initial Study/Mitigated Negative Declaration addressing the potential environmental effects of leasing SMUD owned land to a third party (contractor) to build and operate a 10-megawatt (MW) alternating current (ac) photovoltaic (PV) solar power facility (Rancho Seco PV Solar Project; proposed project).
The proposed project would be located in unincorporated Sacramento County within the boundary of the former Rancho Seco Nuclear Generating Station. A portion of the proposed project site is on land that previously supported PV facilities. SMUD proposes to lease its property to a third party for the construction and operation of a solar facility on approximately 75 acres associated with the former Rancho Seco Nuclear Generating Facility. Project features would include photovoltaic (PV) solar power plant infrastructure, a 45-foot- long overhead subtransmission line, and interconnection equipment, a substation, and switchgear. The proposed solar facility would generate up to 10 MW of electricity. Construction of the proposed project is anticipated to occur between October, 2015 and June, 2016.
Sacramento Municipal Utility District (SMUD) has prepared a Final Initial Study/Mitigated Negative Declaration (IS/MND) addressing the potential environmental effects of rehabilitating the SMUD Headquarters Building and site.
Sacramento Municipal Utility District Headquarters Building and Site Rehabilitation Project (Proposed Project) will be located at 6201 S Street, Sacramento, California. The Proposed Project would consist of rehabilitating the Headquarters Building and site. Key elements proposed include the expansion of the central core of the Headquarters building, the redesign of the main parking area, updated landscaping, and the development of increased physical security concepts (including fencing and cameras) surrounding employee parking areas. SMUD considers the Headquarters Building and site to be significant to their brand and image and desires to rehabilitate the Headquarters Building and 13.66-acre portion of the Headquarters site to support continued use for the foreseeable future. In doing so the building and grounds will be abated of hazardous materials, paths of travel will be updated to comply with ADA standards, traffic and circulation will be improved to provide better pedestrian safety as well as fire truck access and life safety systems will be upgraded to include full fire sprinklers. The Headquarters Building was listed in the National Register of Historic Places (NRHP) in 2010 as an excellent example of Modern International Style. The proposed project would maintain the building and site's place on the historic register. The Proposed Project is anticipated to occur between April 2015 and September 2017.

Sacramento Municipal Utility District (SMUD) has prepared a Final Initial Study/Mitigated Negative Declaration addressing the potential environmental effects of constructing and operating the Station E Substation Project (Proposed Project), located in the City of Sacramento in Sacramento County, California. The Proposed Project consists of installing a new substation with overhead and underground utility lines, steel structures, and electrical equipment to replace an existing substation. The Proposed Project would replace the existing North City Substation, which was constructed in the 1950s and has reached its planned operational end of life. The Proposed Project would meet SMUD's performance objectives by locating the new substation near the load center of the existing service area.
The Proposed Project would involve replacing the existing North City substation with a new substation and corresponding supporting infrastructure on an approximately 15.42 acre parcel. The Proposed Project includes dismantling the existing substation after the new substation enters operation. The Proposed Project does not include any future planned or proposed land uses on the existing substation site. The Proposed Project includes an expansion of capacity at the substation by 20,000,000 volt amperes (20MVA), would serve the same service territory as the existing North City Substation and step down transmission line voltage from 115 kilovolts (kV) to 21kV through power transformers. The existing seven 115kV overhead and underground transmission lines and seven 21kV overhead and underground distribution lines would be transitioned from the existing substation to the location of the new substation.
Sacramento Municipal Utility District has prepared a Recirculated Initial Study/Mitigated Negative Declaration addressing the potential environmental effects of constructing and operating a neighborhood distribution substation that would relocate and expand an existing substation in order to accommodate the County of Sacramento's Hazel Avenue Widening Project.
SMUD is considering two optional locations for the proposed relocated substation. The proposed substation would be at the 4700 block of Hazel Avenue, which is situated on the west side of Hazel Avenue in between Sunset Avenue and Timm Avenue, in the community of Fair Oaks, in Sacramento County, California. The proposed project would also consist of dismantling an existing substation located at 4665 Hazel Avenue and altering the proposed alignment for the overhead 69kV subtransmission line that would connect to the relocated substation.
Sacramento Municipal Utility District (SMUD) has prepared an Initial Study/Mitigated Negative Declaration addressing the potential environmental effects of constructing a new overhead and underground utility line to provide electricity to an existing cellular tower.
The Arroyo Seco Twin Cities Utility Line Project (Proposed Project) would be located near the unincorporated community of Herald, Sacramento County, California. The Proposed Project would consist of installing approximately 7,260 feet (1.38 miles) of overhead and underground utility lines from an existing utility pole to an existing 145-foot cellular tower on the north side of Twin Cities Road, east of Clay Station Road. As part of this project, 13 new utility poles and 3 pull boxes would be installed. Approximately 3,422 feet of utility lines would be installed overhead and the remaining 3,838 feet would be installed underground in 4-inch diameter conduit. The underground trenching would occur within a five-foot wide utility easement and the overhead utility pole installation would occur within a ten-foot wide utility easement. The Proposed Project includes a 25-foot buffer area around the boundary of the utility easement to provide for construction equipment, lay down areas, and staging areas. Construction of new utility line is anticipated to occur between May 2013 and September 15, 2013.
Sacramento Municipal Utility District has prepared an Initial Study/Mitigated Negative Declaration addressing the potential environmental effects of dismantling an existing substation and constructing a new, replacement substation, and altering the proposed alignment for the overhead 69,000-volt (69kV) subtransmission line in order to accommodate the County of Sacramento's Hazel Avenue Widening Project.
The existing Hazel-Timm substation at 4665 Hazel Avenue in the community of Fair Oaks, Sacramento County, California, would be relocated approximately 600 feet to the north to 4733 and 4737 Hazel Avenue. The new, relocated and expanded substation would be called the Hazel-Sunset substation. In addition, as part of the relocation, the new substation location would include sufficient space to accommodate the future expansion of capacity from a single 20-MVA transformer to two 20-MVA transformers as electricity demand increases in the service area.
Construction of the new substation is anticipated to start in spring 2013 and would continue for approximately 5 months. Once the new substation is operational, the dismantling of the old substation would require approximately 3 months starting in fall 2013. Dismantling of the old substation would not start until the new substation is energized and in-service. The proposed change in the subtransmission line extension over Hazel Avenue will occur in spring 2014. Phase I from the American River Bridge to Sunset Avenue would occur in spring 2014, followed by Phase II from Sunset Ave. to Madison Ave. Each phase, replacing the poles and subtransmission line, would require approximately 1 month.
The Sacramento Municipal Utility District (SMUD) has prepared an Addendum to the Final Supplemental Environmental Impact Report #2 (FSEIR #2) for the Solano Wind Project (Phase 1 & 2).
The Addendum to the FSEIR #2 discloses the lack of potential environmental effects of associated with revising the biological resource mitigation measures for avian impacts proposed in the FSEIR #2. The addendum proposed to use mitigation bank credits that provides for long-term protection of special-status avian species and habitats impacted by the development of Solano Wind Project Phase 1 & 2.
The Sacramento Municipal Utility District (SMUD) has issued this Notice of Intent of the Draft Initial Study/Mitigated Negative Declaration (MND) for the SMUD Station A Network 1 Reconductor Project. The purpose of the MND is to identify the potentially significant effects on the environment from the Project; to identify mitigation measures for those potential effects on the Project; and to indicated the manner in which significant effects can be mitigated or avoided. SMUD is the Lead Agency for the Project, including the preparation of the MND. As required by the California Environmental Quality Act (CEQA), under Division 13 of the California Public Resource Code, the Draft MND is being circulated to responsible State and federal agencies and made available to the public for a 30-day review period. This Notice of Intent announces the completion of the Draft MND, where it can be reviewed; the date, time and location of the public meeting and public hearing; and the starting and end date of the public review period.
SMUD proposes the Station A Network 1 Reconductor Project in order to upgrade and replace existing conduit and 12-kilovolt electric lines that connect the substation, Station A, to the 12-KV underground lines at the manhole at 7th and K streets in downtown Sacramento, Ca. The project would consist of installing approximately 1,850 linear feet of conduit in trenches, one 20-foot manhole/vault and three 8-foot by 14-foot manholes through downtown Sacramento. The project route starts at Station A (substation) at 6th and H streets, heads south on 6th Street, turns east on J Street, and then turns south on 7th Street to tie into manhole MH-760 by K Street. A cut-over will be constructed at the intersection of 7th and J streets that will intercept the existing conduits. This project would be constructed in three phases over a period of 165 days.
The Sacramento Municipal Utility District (SMUD) has prepared a Final Initial Study/Mitigated Negative Declaration (FIS/MND) for the SMUD Nature Preserve Mitigation Bank project (Project).
The FIS/MND analyzes the potential environmental effects of constructing and operating the Project. The Project would establish the SMUD Nature Preserve Mitigation Bank (Proposed Project) on approximately 1,132 acres of SMUD-owned property located in southeastern Sacramento County. The Proposed Project will create a multi-species/multi-habitat mitigation bank that provides for long-term protection of special-status species and habitats found with SMUD's service territory (majority of Sacramento County and a portion of Placer County). Bank credits would be used to offset future unavoidable impacts to special-status species and their habitats, wetlands, and oak trees that could result from future public or private agency-approved projects. Elements of the Proposed Project will preserve, enhance, restore and create wetlands and special-status wildlife and plant habitats.
The Sacramento Municipal Utility District (SMUD) has prepared a Final Draft Environmental Impact Report (FEIR) for the SMUD East Campus - Operations Center project (Project). The FEIR is being circulated to commenters and can be viewed on this Web site. A Revised Public Notice was mailed to nearby property owners that announces a change for one of the public meeting dates (see link below).
The Draft Environmental Impact Report (EIR) analyzes the potential environmental effects of constructing and operating the Project in Sacramento County. The EIR identifies potentially significant unmitigated environmental impacts for traffic and air quality. All other potential impacts have been determined to be less than significant after mitigation.
The Project would relocate the existing impacted Corporate Yard that is undersized, provide more efficient operations, and provide a central location to service SMUD's electric infrastructure. The Project would include offices, mechanical shops, maintenance and warehouse buildings, open storage space, fuel island and vehicle wash station, parking for visitors and employees, and flee vehicles. The Project is being designed as a U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) Rating System with the goal of Platinum Certification.
In its continuing commitment to clean renewable power, Sacramento Municipal Utility District (SMUD) proposes to construct and operate the third phase of the Solano Wind Project. SMUD operates and maintains an existing wind project in Solano County (phases 1 and 2) which has installed 102 megawatts (MWs) of wind energy since 2007. Phase 3 will add an additional maximum of 128 MW, totaling up to 230 MWs of clean renewable power.
The project consists of installing up to 75 wind turbine generators and associated facilities in the Montezuma Hill region of southern Solano County, southwest of the town of Rio Vista.
