How Vaulted Deep selects and permits new sites

Facilities like ours are built to last, which makes early decisions especially important. That long lifetime drives how Vaulted develops waste management infrastructure centered on stewardship and permanent containment.

Robust site selection is where we determine safety, environmental protection, and viability of any new potential site. Vaulted screens locations systematically to build our potential project pipeline, identifying sites that meet defined technical, environmental, and regulatory criteria and solve local waste challenges.

Below is a look at how we inform every Vaulted Deep project.

Identifying geology that can safely contain organic material

We start with the subsurface. Vaulted begins with areas where the geology and geomechanics support safe, permanent containment—fully isolated, and far away from drinking water sources. Injection zones are typically located thousands of feet beneath the lowermost underground source of drinking water, and injection zones must have thick, laterally continuous confining layers that serve as natural seals to keep the injected material in place for thousands of years.

Each region has unique geology, so the actual depth and specific rock formations may vary. In all cases, these geologic layers provide an impermeable barrier between the injection zone and drinking water resources.

We map faults, legacy wells (including potentially improperly plugged wells), and other subsurface features to identify and avoid potential leakage pathways or triggers of seismic activity. Historical well data, published studies, and geologic models are evaluated and integrated into containment modeling to validate long-term isolation before a site advances in the development process.

Designing projects to protect groundwater

Only sites with safe geology move into our site-specific design stage. At this stage, site design pairs the geology with engineering to provide multiple sources of protection between the well and the environment.

During design, we establish the parameters for a future well in this specific geology. We verify physical separation between injection zones and underground sources of drinking water in accordance with all applicable federal and state regulatory standards. Site design incorporates a pipe-in-pipe well design, with multiple casing strings cemented to the surface to protect drinking water aquifers over the long life of the well.

Once a site is permitted and operational, Vaulted continuously models pressure, flow, and injectate behavior to confirm containment within the target injection zone. These monitoring and modeling requirements are established during the design phase for each specific site.

In addition to ensuring our own safe operations, Vaulted projects go above and beyond to try and solve local environmental risks the community has historically faced. We prioritize sites where we can address real local waste challenges that threaten groundwater quality (such as PFAS and nutrient run off from land application of waste) and air quality (such as methane and odor from landfilled, incinerated, or land applied waste).

Following a multi-layered permitting and review process

Permitting is a formal, multi-agency review process. Candidate sites only advance to permitting if they meet defined technical, environmental, and regulatory thresholds. We prepare detailed technical and environmental analyses for review by the U.S. Environmental Protection Agency and/or State environmental regulatory agencies in full compliance with the Safe Drinking Water Act and the Underground Injection Control (UIC) program.

Operating a Vaulted site requires more than federal UIC authorization. Vaulted works closely with state agencies and local governments to obtain all necessary permits, which may include state water quality approvals, county land-use permits, and local operational authorizations. Each project must meet the full spectrum of federal, state, and local requirements.

Public participation is a required part of the permitting process. This includes formal public notice and comment periods, as well as Vaulted-initiated community engagement like town hall meetings and informational sessions.

From initial application through permit approval, the permitting process typically takes two years or longer, depending on the scope of technical review and community engagement.

Reassessing and prioritizing our portfolio of potential sites

Potential projects are evaluated continuously throughout the permitting and community engagement process. Vaulted reevaluates in-progress sites as new data, regulatory feedback, or local conditions emerge and compares projects across regions to determine where geology, permitting pathways, and local context best align.

If conditions change, Vaulted may pause, reprioritize, or step back from sites if they no longer support a viable scale or timeline. Resources are allocated to projects with the strongest long-term fundamentals.

Building durable projects for long-term stewardship

Long-term safety and oversight are paramount throughout the lifetime of a Vaulted site. Projects are designed to be monitored, maintained, and ultimately closed in accordance with long-term safety and regulatory requirements.

We monitor wells and site operations continuously, with real-time data transmission and instantaneous shut-in protocols if issues are detected. We are subject to comprehensive oversight and audits, with affirmative obligations to provide data, analysis, and notice of any issues.

This approach allows Vaulted to build a project pipeline across diverse regions while holding every site to strict technical, environmental, and regulatory standards. The result is infrastructure that protects our land, air, and water.
