Based on the information you provided to us, Nationwide Permits (NWP) 3, Maintenance and 18, Minor Discharges (Federal Register December 27, 2021 Vol. 86, No. 245), authorizes your proposal as depicted on the enclosed drawings dated June 17, 2024.

In order for this authorization to be valid, you must ensure the work is performed in accordance with the enclosed NWP’s 3 and 18, Terms and Conditions.

We have reviewed your project pursuant to the requirements of the Endangered Species Act, the Magnuson-Stevens Fishery Conservation and Management Act and the National Historic Preservation Act. We have determined this project complies with the requirements of these laws provided you comply with all of the permit general and special conditions.

The National Park Service completed National Historic Preservation Act (NHPA) and Section 7 Endangered Species Act (ESA) consultations for the proposed activities (U.S. Fish and Wildlife Service reference number 2023-0057170). For the purpose of this Department of the Army authorization, we have determined this project will comply with the requirements of these laws provided you comply with all of the permit conditions. We have determined the permit action is sufficiently addressed in their ESA

-2-and NHPA consultation documents. By this letter we are advising you and the U.S. Fish and Wildlife Service, in accordance with 50 CFR 402.07 and 50 CFR 600.920(b), that this agency has served as the lead Federal agency for the ESA consultation responsibility for the activities described above.

Please note that National General Condition 21, Discovery of Previously Unknown Remains and Artifacts, found in the Nationwide Permit Terms and Conditions enclosure, details procedures that must be followed should an inadvertent discovery occur. You must ensure that you comply with this condition during the construction of your project.

The authorized work complies with the U.S. Environmental Protection Agency’s (EPA) Water Quality Certification (WQC) requirements for these NWPs. No further coordination with EPA for WQC is required.

You have not requested a jurisdictional determination for this proposed project.

If one is requested, please be aware that we may require the submittal of additional information to complete the JD and work authorized in this letter may not occur until the JD has been completed.

Our verification of this NWP authorization is valid until March 14, 2026, unless the

NWP is modified, reissued, or revoked prior to that date.

You must also obtain all local, State, and other Federal permits that apply to this project.
