NWP 24: Indian Tribe or State Administered Section 404 Programs

Any activity permitted by a state or Indian Tribe administering its own section 404 permit program pursuant to 33 U.S.C. 1344(g)-(l) is permitted pursuant to Section 10 of the Rivers and Harbors Act of 1899. (Authority: Section 10) Note 1: As of the date of the promulgation of this NWP, only New Jersey and Michigan administer their own Clean Water Act Section 404 permit programs.

Acreage limit

The 2026 rule states no acreage limit for NWP 24. Eligibility turns on the activity description in the rule text and the general conditions that apply, not on a numeric cap.

Pre-construction notification: Not required

NWP 24 carries no notification clause in the 2026 rule. Activities authorised solely under this permit do not need to file a PCN under general condition 32.
