Project 001 · Understand How This Decision Was Made
Pilot domestic purification line
Approve a pilot-scale domestic purification line at the Imperial Valley site.
Approved
Everything below reflects exactly what was known as of 2026-06-07 — the evidence available, the risks on record, and the reasoning that followed. Nothing here has been revised with hindsight.
Decision Rationale
HighApproved based on available evidence at the time; alternatives carried materially higher near-term cost or schedule risk.
Supporting Evidence Cited
| ID | Date | Category | Confidence | Notes |
|---|---|---|---|---|
| EV-023 | 2026-03-11 | Geology | Medium | Preliminary economic assessment (2025) estimated a sustaining capital requirement roughly 15% below Deposit A due to shallower overburden, pending confirmation drilling. |
Evidence Available Then
86 records existed as of 2026-06-07| ID | Date | Category | Notes |
|---|---|---|---|
| EV-085 | 2026-06-05 | Supply Chain | Quoted delivered pricing from the engaged supplier is approximately $145–160 per tonne, consistent with regional industrial acid market data from early 2026. |
| EV-084 | 2026-06-04 | Supply Chain | Only one sulfuric acid supplier has been engaged in preliminary discussions; two additional regional suppliers were contacted but have not responded as of this evidence date. |
| EV-083 | 2026-06-03 | Market | Integrator has indicated openness to a shorter qualification cycle than cell manufacturers, given less stringent cycle-life requirements for stationary storage applications. |
| EV-082 | 2026-06-02 | Market | Grid Storage Integrator West's projected annual material demand, per its public capacity expansion announcements, is estimated at 8,000–12,000 tonnes by 2028 — meaningful but secondary to primary battery-cell offtake volume. |
| EV-081 | 2026-06-01 | Market | Consortium's technical qualification standard (per published supplier requirements) is broadly similar to Cell Maker A's protocol but includes an additional carbon-footprint disclosure requirement. |
| EV-080 | 2026-05-29 | Market | European Battery Consortium's public sourcing roadmap targets 30% non-Asian anode material supply by 2030, a stated policy goal consistent with program positioning but not yet a signed commitment. |
| EV-079 | 2026-05-28 | Environmental | No federally listed endangered species habitat has been identified within the immediate project footprint per the most recent U.S. Fish and Wildlife Service critical habitat mapping. |
| EV-078 | 2026-05-27 | Environmental | Colorado River Delta habitat review precedent from a comparable cross-border infrastructure project suggests binational environmental consultation could add 6–12 months to permitting if triggered. |
| EV-077 | 2026-05-26 | Environmental | Comparable processing facilities elsewhere have achieved PM10 compliance using baghouse filtration systems with a documented capture efficiency above 99.5%. |
| EV-076 | 2026-05-25 | Environmental | Salton Sea Air Basin is currently classified as nonattainment for PM10 under federal standards, which imposes additional emissions offset requirements on new industrial sources. |
| EV-075 | 2026-05-22 | Permitting | A preliminary wetlands delineation survey commissioned for this program identified no jurisdictional wetlands within the primary site boundary, though the adjacent water infrastructure corridor remains under review. |
| EV-074 | 2026-05-21 | Permitting | Army Corps jurisdictional determination requests for comparable water-adjacent industrial sites in the region have taken a median of 14 months to resolve per publicly available Corps case data. |
| EV-073 | 2026-05-20 | Permitting | County planning staff confirmed in a pre-application meeting that no general plan amendment would be required for the current site configuration, reducing procedural risk. |
| EV-072 | 2026-05-19 | Permitting | Imperial County's zoning approval process for the relevant land use classification has historically required a public hearing period of 60–90 days, per county planning department procedural guidelines. |
| EV-071 | 2026-05-18 | Permitting | DTSC pre-application consultation, where used by comparable applicants, correlated with an average 20% reduction in total review time in a sample of 14 similar California facility permits. |

Risks Known Then
44 risks logged as of 2026-06-07Madagascar jurisdictional policy risk
Madagascar's export policy for graphite has been broadly stable but is not contractually locked in.
LowMonitoring
Mozambique jurisdictional policy risk
Mozambique's regulatory and export policy environment for critical minerals is still developing.
MediumOpen
Production tax credit policy risk
The critical minerals production tax credit is subject to future policy change.
MediumMonitoring
Offtake prepayment structuring risk
Prepayment facility terms are still under negotiation and could affect capital structure assumptions.
LowMonitoring
Federal loan guarantee approval uncertainty
Department of Energy loan guarantee approval timing and terms remain uncertain.
MediumOpen
Synthetic feedstock cost volatility
Petroleum coke feedstock pricing for the synthetic hedge pathway has shown recent volatility.
LowMonitoring
Process chemical supplier concentration risk
Sulfuric acid supply for purification currently depends on a single candidate supplier.
MediumOpen
Grid storage customer volume uncertainty
Grid storage integrator demand volume is less certain than primary battery-cell offtake.
LowMonitoring
Unknown Factors
- ?Full-scale cost confirmation pending
- ?Long-term policy stability unconfirmed
