Army Corps Tweaks Permits to Ease Building While Protecting Waters
Published Date: 1/8/2026
Rule
Summary
The Army Corps of Engineers is updating 56 existing Nationwide Permits and adding one new permit to help protect our waters while making it easier to get approval for certain projects. These permits, which affect builders, developers, and utility companies, will start on March 15, 2026, and last until March 15, 2031. The changes aim to balance environmental care with smoother project approvals, with no big new costs expected.
Analyzed Economic Effects
6 provisions identified: 3 benefits, 2 costs, 1 mixed.
Nationwide Permits Reissued for Five Years
The Corps is reissuing 56 existing Nationwide Permits and issuing one new NWP; the full set of 57 NWPs goes into effect on March 15, 2026 and will expire on March 15, 2031. These NWPs replace prior versions so businesses that rely on NWP authorizations should plan under the 2026 NWPs for activities after March 14, 2026.
Faster Permit Review and 45‑Day Rule
In Fiscal Year 2024 the average processing time for an NWP pre-construction notification (PCN) was 55 days, compared with 253 days for a standard individual permit. If a Corps district does not respond to a complete PCN within 45 days, the project proponent may generally assume the activity is authorized, except for specified exceptions (e.g., certain Endangered Species, Historic Properties, Wild and Scenic Rivers, NWP 49, and activities under General Conditions 16, 18, 20, and 31).
One‑Year Grandfathering for Ongoing Projects
Activities authorized under the 2021 NWPs that have commenced or are under contract to commence by March 14, 2026 will have until March 14, 2027 to complete. Projects not commenced or not under contract by March 14, 2026 will need reauthorization under the 2026 NWPs or an individual permit if they no longer qualify.
Finfish Mariculture Permit Not Reissued
The Corps is not reissuing NWP 56 (finfish mariculture activities) in this final action. Operators or developers that relied on NWP 56 will need to seek other authorization pathways for those activities going forward.
Case‑by‑Case Conditions and Mitigation Risk
District engineers reviewing PCNs can add activity-specific conditions (for example, time-of-year restrictions, best management practices, or compensatory mitigation) or require an individual permit if they determine adverse effects will be more than minimal. Regional conditions may also require additional PCNs or limits.
New Permit for Fish Passage Projects
The Corps is issuing one new Nationwide Permit (NWP A) to authorize activities that improve the passage of fish and other aquatic organisms. This creates a nationwide authorization pathway for those specific restoration or infrastructure activities starting March 15, 2026.
