# 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                           ( print page 27991)                        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 September 3, 2020, NMFS received an application from the USACE requesting authorization for take of marine mammals incidental to confined blasting associated with the Port Everglades Harbor Deepening and Widening Project, Broward County, Florida. We provided comments on the application and the USACE submitted a revised version on April 3, 2021. We deemed the application adequate and complete on April 29, 2021. The requested regulations under which we would issue the requested LOA would be valid for five years, August 2024 and August 2029. The USACE plans to conduct confined underwater blasting to deepen and widen the Port Everglades harbor and entrance channel. Blasting may incidentally expose marine mammals to elevated levels of noise, thereby 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 proposed project is to provide for increased navigational safety, efficiency, and improved economic conditions for ships calling at Port Everglades. The existing federal channel project depth of 42 feet at Port Everglades does not provide an adequate, safe depth for large tankers and container ships currently visiting the harbor. Furthermore, the next generation of container ships and oil tankers requires significantly more channel depth to operate efficiently and a wider and deeper entrance channel will greatly improve the safety of navigation. To achieve the proposed deepening and widening of Port Everglades, pretreatment of rock areas may be required using confined underwater blasting where dredging or other rock removal methods are unsuccessful due to the hardness and massiveness of the rock. The USACE anticipates a maximum of 280 confined, stemmed blasts would occur over the life of the LOA, if issued, at a rate of one blast per day. Blasting operations may take place six days a week with a maximum of one blast occurring per day. Confined underwater blasting operations will be prohibited between November 15 and March 15 in order to avoid take of the West Indian Manatee (                    *Trichecus manatus*). Blasting would occur in six designated areas: The outer entrance channel, inner entrance channel, main turning basin, widener, south access channel, and turning notch. The USACE's application contains mitigation and monitoring measures designed to reduce impacts to marine mammals. The application also contains proposed marine mammal and acoustic 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.
