# PermitBird: the complete 2026 nationwide permit ruleset Source: 91 FR 768, published 2026-01-08, effective 2026-03-15, expires 2031-03-15. Docket COE-2025-0002. Compiled 2026-07-27. 57 permits. The 57 NWPs are numbered 1-25, 27-46, 48-55 and 57-60. NWPs 26, 47 and 56 are shown as [Reserved] in the final rule and are not active permits. 56 existing NWPs were reissued with modifications and one new NWP (60) was issued. ## General conditions compiled ### General Condition 32: Pre-Construction Notification Where required by the terms of the NWP, the prospective permittee must submit a pre-construction notification (PCN) to the district engineer as early as possible. The district engineer must determine whether the PCN is complete within 30 calendar days of receipt and, if incomplete, request the additional information within that 30-day period. The permittee may not begin work until either (1) written notice from the district engineer that the activity may proceed, or (2) 45 calendar days have passed from the district engineer's receipt of the complete PCN without written notice. Longer waits apply where general condition 18 (Endangered Species) or 20 (Historic Properties) notification was required, or where a written waiver to exceed NWP limits is needed. If the district or division engineer notifies the permittee in writing within 45 calendar days that an individual permit is required, work cannot begin until that permit is obtained. Review period: 45 calendar days. Confidence: verified.

Applies to: Per single and complete project, for those NWPs that carry an acreage loss limit (NWPs 12, 14 (non-tidal), 21, 29, 39, 40, 42, 43, 44, 50, 51, 52, 57, 58, 59). Not all NWPs have an acreage limit; several are self-limiting.. Confidence: verified. - 1/10-acre pre-construction notification threshold: 0.1 acres. Applies to: For NWPs that have an acreage PCN threshold, the Corps set that threshold at 1/10-acre (e.g. NWPs 12, 14, 51, 57, 58, 60). NWP 18 also carries a 1/10-acre loss limit as a permit condition.. Confidence: verified. - 3/100-acre stream bed compensatory mitigation threshold: 0.03 acres. Applies to: Losses of stream bed exceeding 3/100-acre will generally require compensatory mitigation. Established in the 2021 NWPs and retained in 2026.. Confidence: verified. - 1/10-acre wetland loss compensatory mitigation threshold: 0.1 acres. Applies to: Compensatory mitigation threshold for loss of wetlands, used together with the 3/100-acre stream bed threshold and the acreage impact limits.. Confidence: verified. - 45 calendar day district engineer PCN review period: 45 calendar days. Applies to: General condition 32(a). If no written response is received within 45 calendar days of the district engineer's receipt of a COMPLETE PCN, the permittee may proceed, subject to the GC 18 / GC 20 and waiver exceptions.. Confidence: verified. - 30 calendar day PCN completeness determination: 30 calendar days. Applies to: General condition 32(a). The district engineer must determine whether a PCN is complete within 30 calendar days of receipt and request any additional information within that period. The 45-day clock runs from receipt of the COMPLETE PCN.. Confidence: verified. - 300 linear feet of stream bed limit - NOT in force for the 2026 cycle: NOT IN FORCE / not compiled. Applies to: The 300 linear foot stream bed impact limit was REMOVED from 10 NWPs (21, 29, 39, 40, 42, 43, 44, 50, 51, 52) in the 2021 NWPs. Many commenters asked the Corps to reinstate it for 2026; the Corps declined and the limit was NOT reinstated. The Corps instead relies on the 1/2-acre impact limit, PCN requirements, and division/district engineer discretionary authority. Do not apply a 300 linear foot limit to 2026 NWP activities.. Confidence: verified. - 500 foot bank stabilization length limit (NWP 13): 500 linear feet. Applies to: NWP 13 only. Waivable by written district engineer determination; no waiver may be issued for a bulkhead greater than 1,000 feet in length along the bank..
