h. Threatened' and Endangered Species: In accordance with Section 7 of the
Endangered Species Act of 1973, as amended, CEMRO requested that the USFWS identify listed
or proposed-for-listing (candidate) federally threatened or endangered species that may occur
within the project area. The USFWS provided the list in Table 2.

The peregrine falcon, interior least tern, pallid sturgeon, and American burying beetle
are federally-listed endangered species that may occur in the project area. The bald eagle,
piping plover and western prairie fringed orchid are federally-listed threatened species that may
occur in the project area. No designated 'critical habitat' occurs within the project area.

The bald eagle may occur as a migrant and/or winter resident in the area. Peregrine
falcons are associated with wetlands and open areas and may follow the Missouri River Valley
during migration, The interior least tern and piping plover nest on sandbars and may occur
along the Missouri River during migration. The pallid sturgeon is apparently rare throughout
its historic range and only a few have been captured from the Missouri River in recent years.
The American burying beetle may be found along major watercourses, such as the Missouri
River, where deciduous forests with significant amounts of humus and top soil exist (U.S. Fish
and Wildlife Service 1994),

The western prairie fringed orchid was originally widespread in eastern Nebraska, but
its populations have declined due to conversion of habitat to cropland and overgrazing. The
orchid is restricted to native, upland, dry-mesic to wet-mesic tall-grass prairie hay meadow and
sedge meadow communities (USFWS 1986), It is an inhabitant of tall-grass calcareous silt loam
or sub-irrigated sand prairies (USFWS 1994).

Table 2 also lists Category I and 2 candidate species which may be found in Otoe
county. Category I candidate species are those for which the USFWS has data to support listing
as threatened or endangered, and listing is anticipated. Category 2 candidate species are those
for which the USFWS is seeking additional information in order to determine their biological
status. Candidate species have no legal protection under the Endangered Species Act.

i. Historic Properties and Archeological Resources: In order to assess the potential
for cultural resources on the project site, including both archeological resources and standing
structures, an investigation of historic maps, a number of historic documents, and site files was
conducted at the Nebraska State Historic Preservation Office (SHPO). A pedestrian cultural
resources reconnaissance was also conducted.

There are no standing structures located on the project site, and a review of the historic
structures survey files showed that there are no structures that are on the National Register of
Historic Places or that are considered eligible for listing on the National Register recorded near
the project site. No cultural resources that appeared to be potentially eligible for the National
Register of Historic Places were observed during the site reconnaissance,
