S. To minimize risks to the federally threatened West Indian manatee (Trichechus manatus), the NPS would implement the Manatee Protection Measures for South Carolina proposed by the USFWS (presented in EA, Appendix A).

T. Refer to U.S. Army Corps of Engineers (USACE) permit provided by NPS for additional conditions.

U. To minimize risks to sea turtles, Contractor shall utilize turbidity booms to mitigate impacts to water quality.

V. Park biologists to conduct a survey for West Indian manatee and federally listed sea turtles in the project area prior to construction. If signs of these species are identified within the project area, mitigation measures to avoid impacts to the manatee and sea turtles would be employed, including restricting construction to periods of inactivity (typically November through March) to the extent possible.

W. Contractor personnel would be responsible for observing all water-related activities for the presence of protected species.

X. If a sea turtle is observed within 150 feet of the construction area, construction would cease until the sea turtle is observed departing the project area on its own or after 20 minutes have passed since the sea turtle is last observed within the construction area.

BB. Bird Protection Acts

1. In order to protect birds under the Migratory Bird Treaty Act (MBTA, 16 U.S.C. 703–712), all construction work performed between February 1 and August 31 requires a site survey, to be performed by trained NPS staff. The survey must be completed within two weeks prior to the start of construction. Additional surveys will be required after periods of no work exceeding two weeks. The Contractor will be required to avoid cutting down trees with active nests, however, other work would be permitted to continue. Some species may also require a buffer around active nests where work cannot occur.

a. Contractor shall request a site survey a minimum of one month prior to mobilization.

CC. Fort Sumter and Fort Moultrie - Piping Plover. At Fort Sumter, piping plovers use the intertidal wetlands for foraging. During construction, piping plovers may be impacted due to noise disturbance and may avoid the area. Potential nesting habitat for piping plover occurs in the sandy beach area well south of the project area. To minimize impacts on the piping plover, if this species enters the construction area while construction operation is underway, construction would cease until the bird has left the area. In addition, park staff would ensure no active nests are located in the beach area south of the project area from mid- March through August.

DD. Fort Sumter and Fort Moultrie - Red Knot. The red knot has been observed at Fort Sumter;

however, this species is not common. Red knots will use tidal flats in the winter, but they migrate to summer breeding habitat in tundra environments. If red knots are in the vicinity of the project area during construction, there is potential for impacts due to noise disturbance. Like the piping plover, if this species enters the construction area while construction operation is underway, construction would cease until the bird has left the area.

EE. Floodplains

1. The entirety of the park is located in the Federal Emergency Management Agency (FEMA)
