# SUPPLEMENTARY INFORMATION:

## Background

                    Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361*et seq.*) direct the Secretary of Commerce (as delegated to NMFS) to allow, upon request, the incidental, but not intentional, taking of small numbers of marine mammals by U.S. citizens who engage in a specified activity (other than commercial fishing) within a specified geographical region if certain findings are made and either regulations are issued or, if the taking is limited to harassment, a notice of a proposed authorization is provided to the public for review.                

An incidental take authorization shall be granted if NMFS finds that the taking will have a negligible impact on the species or stock(s), will not have an immitigable adverse impact on the availability of the species or stock(s) for subsistence uses (where relevant), and if the permissible methods of taking and requirements pertaining to the mitigation, monitoring and reporting of such takings are set forth.

NMFS has defined “negligible impact” in 50 CFR 216.103 as an impact resulting from the specified activity that cannot be reasonably expected to, and is not reasonably likely to, adversely affect the species or stock through effects on annual rates of recruitment or survival.

The MMPA states that the term “take” means to harass, hunt, capture, kill or attempt to harass, hunt, capture, or kill any marine mammal.

Except with respect to certain activities not pertinent here, the MMPA defines “harassment” as: any act of pursuit, torment, or annoyance, which (i) has the potential to injure a marine mammal or marine mammal stock in the wild (Level A harassment); or (ii) has the potential to disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns, including, but not limited to, migration, breathing, nursing, breeding, feeding, or sheltering (Level B harassment).

## Summary of Request

On April 17, 2024, NMFS received an application from the USACE requesting authorization for take of marine mammals incidental to in-water construction activities associated with the DERP in Hood Canal. We provided comments on the application and the USACE submitted a revised version on September 27, 2024. The application was deemed adequate and complete on November 5, 2024. The requested regulations under which we would issue the requested LOA would be valid for 5 years, November 2025 through October 2029. The USACE's DERP would reconnect floodplain and intertidal wetlands to improve tidal exchange, sediment transport, and estuary development plans to restore the Duckabush River Estuary. Construction-related activities include building temporary work platforms, bridge demolition, bridge construction, road realignment, channel excavation, causeway and training berms demolition. Construction activities are expected to disturb nearby pinnipeds, resulting in incidental take by Level B harassment only. Therefore, the USACE requests authorization to incidentally take marine mammals.

## Specified Activities

The purpose of the DERP is to reconnect floodplain and intertidal wetlands to improve tidal exchange, sediment transport, and estuary development plans to restore the Duckabush River Estuary. Construction-related activities include building temporary work platforms, bridge demolition, bridge construction, road realignment, channel excavation, and causeway demolition.

                    The USACE anticipates construction will take up to 764 workdays across 48 months to complete. Time estimates assume that construction will operate 8 hours per day, 5 days per week for most of the project and 12 hours per day, 7 days per week for some components of the work. The number of work days per year would range from 28 (Year 1) to 263 (Years 2 and 3). Take by Level B harassment has been requested for harbor seal (                    *Phoca vitulina*). The USACE's application contains mitigation and monitoring measures designed to reduce impacts to marine mammals. The application also contains proposed marine mammal monitoring and reporting plans.                

## Information Solicited

                    Interested persons may submit information, suggestions, and comments concerning USACE's request (see                     **ADDRESSES**                    ). NMFS will consider all information, suggestions, and comments related to the request during the development of proposed regulations governing the incidental taking of marine mammals by USACE, if appropriate.
