Trusted by Los Angeles since 2008

At Terminal Island, our partner Advantek manages 20% of the biosolids from the City of Los Angeles and permanently locks them away thousands of feet underground—far from any drinking water source, in rock formations selected for their natural storage properties. This provides the city with a reliable, long-term disposal alternative to land application that keeps biosolids completely isolated from surface ecosystems. Unlike land application, which can be limited by wet weather, deep underground injection provides a reliable, year-round disposal option regardless of weather conditions.

Vaulted also generates carbon credits from this material stored deep underground, out of the atmosphere.

01

Regulated operations

Terminal Island operates under a Class V Underground Injection Control permit issued by the EPA. In 2019, the EPA issued a comfort letter confirming the safety of the facility’s operations, and the permit was renewed for a 10-year term in 2022. Operations are continuously monitored and reported to state and federal regulators.
02

Seismicity

Los Angeles sits in a seismically active region, and that’s exactly why Terminal Island’s specific geology was carefully screened and selected. The facility targets deep, stable rock formations not connected to active fault systems. Terminal Island has operated through numerous regional seismic events without incident, and there is real-time seismic monitoring to ensure rapid response.
03

Proven technology

This facility is operated by our partner Advantek Waste Management Services, which commercialized the core technology behind all of our sites, and later spun out Vaulted. Terminal Island’s long safety record under Advantek is a proof point for the subsurface approach Vaulted uses to manage organic waste across the country.
