Will the USACE complete the Donlin Gold SEIS by June 2027?
Current Prediction
Why This Question Matters
The SEIS remand is the primary remaining federal regulatory hurdle. The Regulatory Reader assessed ELEVATED but TRENDING POSITIVE exposure. Timely SEIS completion would reduce the regulatory overhang and move the assessment toward DIMINISHING. Delay would extend uncertainty by years and provide Earthjustice new grounds for legal challenge.

The USACE proposed mid-2027 completion under FAST-41, which provides schedule accountability. However, federal environmental reviews are notorious for delays. The SEIS is a supplemental analysis on a narrow issue (tailings facility impact), which should be more manageable than a full EIS. But Earthjustice will likely challenge the process at every step. The FAST-41 program adds accountability but doesn't prevent delays from public comment periods, agency coordination, or political changes. Historical base rate for federal environmental reviews completing on schedule is low.
Breaking this down: the SEIS was ordered June 2025, targeting mid-2027 completion — a 24-month timeline. Federal supplemental EIS processes typically take 18-36 months. The FAST-41 program helps but doesn't guarantee adherence. Key risks: (1) Earthjustice may file procedural motions to delay, (2) public comment period extensions, (3) scope creep if analysis reveals additional issues, (4) political administration changes affecting USACE priorities. The narrow scope (tailings facility analysis only) is the strongest argument for on-time completion.
The favorable factors: (1) FAST-41 program with published schedule, (2) narrow scope — supplemental, not full EIS, (3) Alaska Supreme Court track record favoring Donlin, (4) existing permits remain in effect (reducing urgency for opposition delay tactics). The unfavorable factors: (1) federal review delays are common, (2) Earthjustice is well-funded and persistent, (3) public comment periods can extend timelines, (4) USACE resource constraints. On balance, I give ~40% probability to on-time completion, acknowledging that federal timelines frequently slip by 6-12 months.
Federal environmental reviews almost never complete on time. The SEIS is supplemental (narrower scope) which helps, but the FAST-41 program is relatively new and its effectiveness at preventing delays is unproven. Earthjustice will challenge the process. The 24-month timeline from order to completion is ambitious for any federal environmental review involving a controversial project. Mid-2027 is the target — I expect a 6-12 month delay to early-mid 2028.
The SEIS scope is genuinely narrow — focused on potential release from the tailings storage facility, not a reopening of the full EIS. This significantly reduces the analysis required. The FAST-41 program creates a published schedule with federal accountability. The USACE has committed to this timeline publicly. However, the public comment period could extend the schedule, and Earthjustice will maximize procedural delays. I assign ~40% probability, higher than a typical federal review because the supplemental scope is limited.
The USACE's proposed mid-2027 date under FAST-41 is a genuine commitment, not just an aspiration. FAST-41 requires agencies to publish schedules and be accountable. However, 'mid-2027' could mean July 2027 — and the resolution date is June 30, 2027. This creates a narrow window. If 'mid-2027' means any time between May-August 2027, completion by June 30 specifically is a tighter bar than the stated target. Adjusting slightly downward for this timing precision issue.
Federal environmental reviews rarely complete on schedule. Even with FAST-41 and narrow scope, delays from public comments and Earthjustice opposition are likely. ~33% probability of completion by June 2027.
FAST-41 and narrow SEIS scope are the strongest factors favoring timely completion. But federal processes have inherent uncertainty. Earthjustice persistence adds delay risk. ~37% probability, slightly above base rate for federal reviews due to favorable factors.
The base rate for federal environmental reviews completing on time is low, probably 25-35%. FAST-41 and narrow scope add maybe 5-10pp. But Earthjustice opposition subtracts some of that. Net: ~34%.
Resolution Criteria
Resolves YES if the USACE publishes the final SEIS document by June 30, 2027. Resolves NO if the SEIS has not been published by that date.
