SMUD is planning to build a new substation in Sacramento at the north end of 20th Street, north of C Street and the Union Pacific Railroad tracks. The new Station E Substation will replace the North City Substation. Constructed in the 1950s, the North City Substation is nearing the end of its planned operational use.

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 safe delivery to homes and businesses. The Station E Substation will directly serve the midtown and downtown areas, improving energy reliability and capacity.

Environmental enhancements

Environmental leadership is one of SMUD’s core values. Our environmental clean-up effort will leave the area significantly cleaner and safer than its current condition.

SMUD plans to invest up to $13 million to haul away burn waste that has been on the site for decades and to prepare the site for substation construction currently planned for the end of the year. An impermeable cap will be installed on a portion of the site that will not be used to construct the substation. The cap will seal the ground area to prevent waste from being uncovered and posing a risk to public health or the environment.

Anticipated activities

  • Excavate and remove approximately 64,000 tons of waste material; fill excavated area with new or existing soil that meets safety standards
  • Utilize a haul route that minimizes truck traffic impacts
  • Implement dust control strategies
  • Continuously monitor, inspect and manage all operations for health and safety
  • Continue to collaborate with Sacramento County Environmental Department and State agencies, including CalRecycle, Central Valley Regional Water Quality Control Board and
  • Department of Toxic Substances Control to ensure compliance with the approved soils management plan
  • Ensure the site design and all waste removal activities comply with state and local solid waste regulations
  • Provide ongoing communication with nearby residents and interested stakeholders to ensure the community is well informed about waste removal and substation construction

Project timeline and status

Environmental clean-up efforts are expected to begin in the spring of 2018 and continue throughout the summer of 2018. Substation construction is expected to begin by the end of 2018 and be complete in 2020.

Phase 1B construction status: 8/8/18

Construction has been underway for just over 100 days, mainly focused on excavation and removal of waste materials. Project excavation is nearly 90% complete and progressing well.  Contaminated/non-suitable material removed from the site to date is approximately 15,000 cubic yards and broken down by class below:

Material Type

Cubic Yards

Number of Truckloads

Class I

12,227

696

Class II

1,919

147

Backfill and additional materials using haul route

With the excavation nearing completion, we'll begin importing 45,000 cubic yards from Bell Marine, using internal roads we connected between the two locations. After the Bell Marine material is exhausted, we'll import from another local source less than 2 miles away. The import from the second source is anticipated to begin at the end of August and continue for approximately 18 working days.

We anticipate utilizing approximately 20 trucks per day, making 10 trips each for this final soil import. We have estimated an additional 60,000 cubic yards of soil is needed to bring this phase of the project to grade.  These trucks will utilize the designated haul route as planned.
