Info

Paducah Site Upland mixed hardwoods contain a variety of upland and transitional species. Dominant species include oaks, shagbark and shellbark hickory, and sugarberry (CH2M Hill 1991a). Undergrowth may vary from open, with limited vegetation for more mature stands of trees, to dense undergrowth similar to that described for a scrub-shrub community. Wildlife Wildlife species indigenous to hardwood forests, scrub-shrub, and open grassland communities are present at the Paducah Site. Grassy fields are frequented by rabbits, mice, songbirds, and a variety of other small mammals and birds. Redwing blackbirds, killdeer, cardinals, mourning doves, bobwhite quail, meadowlarks, warblers, sparrows, and red-tailed hawks have been observed in such areas. Scrub-shrub communities support a variety of wildlife including opossums, voles, moles, raccoons, gray squirrels, killdeer, bluejays, redwing blackbirds, bluebirds, cardinals, mourning doves, shrike, warblers, turkeys, and meadowlarks. Deer, squirrels, raccoons, turkeys, songbirds, and great horned owls are found within the mature woodlands of the DOE reservation (CH2M Hill 1991a). In addition, the Ohio River serves as a major flyway for migratory birds which are occasionally seen on the Paducah Site (DOE 1995). Amphibians and reptiles are common throughout the Paducah Site. Amphibians likely to inhabit the area include the American and Woodhouse's toads. Reptiles include the eastern box turtle and several species of snakes. Also, fish populations in Bayou and Little Bayou creeks are numerically dominated by various species of sunfish (DOE 1995). Threatened and Endangered Species A threatened and endangered species investigation identified federally listed, proposed, or candidate species potentially occurring at or near the Paducah Site (COE 1994). Currently, potential habitat for ten species of federal concern exists in the study area (Table 2.2). Seven of these species are listed as endangered under the Endangered Species Act, one is listed as threatened, and two are candidate species which may later be proposed for listing. All are animal species, nine of which are associated with the Ohio River. Of note, significant potential summer habitat was identified for the Indiana bat, a federally listed endangered species. However, no federally listed or candidate species have been found on DOE property at the Paducah Site. Also, no property at the Paducah Site has been designated as critical habitat in accordance with the Endangered Species Act of 1973. Cultural Resources In a study area of about 4860 ha (12,000 acres) in and around the Paducah Site, there are 35 sites of cultural significance recorded with the State Historic Preservation Officer and several more unrecorded sites (COE 1994). Most of these sites are prehistoric and located in the Ohio River floodplain. Six of the sites are on DOE property at PGDP. None of the sites are included in, or have been nominated to, the National Register of Historic Places although some are potentially eligible. Further assessment is needed with regard to the historical significance of PGDP facilities. Site Program Missions DOE has three major programs at the Paducah Site - Environmental Restoration, Waste Management, and Enrichment Facilities. The mission of the Environmental Restoration Program is to ensure that releases from past operations and waste management at the Paducah Site are investigated and that appropriate remedial action is taken for protection of human health and 1-6 Site Operation and Overview
.- Annual Site Environmental Report for 1999 the environment in accordance with the Federal Facilities Agreement (FFA) (DOE 1998). The mission of the Waste Management Program is to characterize and dispose of the legacy waste stored on-site in compliance with various Federal Facilities Compliance Agreements. The primary mission of the Enrichment Facilities Program is to maintain safe, compliant storage of the DOE depleted UF 6 inventory pending final disposition of the material and to manage facilities and grounds not leased to USEe. The <strong>environmental</strong> monitoring summarized in this report supports all three programs. Site Operation and Overview 1-7
