169 to the west, are currently operating as mines, thus the potential for affecting any surrounding sensitive resources is minimal. Are any state-listed (endangered, threatened or special concern) species, rare plant communities or other sensitive ecological resources such as native prairie habitat, colonial waterbird nesting colonies or regionally rare plant communities on or near the site? XYes m No If yes, describe the resource and how it would be affected by the project. Indicate if a site survey of the resources has been conducted and describe the results. If the DNR Natural Heritage and Nongame Research program has been contacted give the correspondence reference number: (NHNRP Contract # ERDB 20030175) The Natural Heritage and Nongame Research Program of the DNR was contacted to determine if there were any rare plant or animal species or significant natural features within an approximate one-mile radius of the Site. The database represents the most complete source of data on rare and significant natural features and species. The information in the database is generated from an ongoing county-by-county survey of such occurrences. A survey for Sherburne County has been completed. The DNR response is provided as Attachment C. The DNR information identifies three known occurrences of rare species or natural features for the area searched. The first is a rare feature occurrence noted as the Oak Woodland-Bmshland (Central #4). According to the DNR, this feature is located approximately 6,000 feet northwest of the Site and is not anticipated to be affected by the project at the Site. The two remaining occurrences are rare species identified as Emydoidea blandingii (Blanding's Turtle). Two occurrences of the Blanding's Turtle have been documented in area of the Site. The first occurrence was in 1996 and was located south of the Site. The second occurrence was in June 2002, east of the Site. According to the DNR, Blanding's Turtles spend much of their time in shallow wetlands and nest in open, sandy uplands up to one mile from wetlands. Nesting occurs in June and eggs hatch in September. The young turtles then enter deep wetlands where they spend the winter in soft sediments. According to the DNR no occurrences of the Blanding's Turtle have been documented on the Site. A site survey for Blanding's Turtles has not been conducted. Describe measures to minimize or avoid adverse impacts. As recommended by the DNR, flyers with an illustration of the Blanding's Turtle will be distributed to all site workers. If observed, any turtles in imminent danger will be moved by hand out of harms way to a safe location. Any turtles observed that are not in danger will be left undisturbed. All construction areas will be surrounded by silt fencing to keep turtles from entering construction areas. The silt fencing will be removed after the area is re-vegetated. Wetlands will not be dredged or filled and all wetlands will be protected from pollution sources. Graded areas will be re-vegetated with standard MN DOT seed mixtures and the terrain will be left with as much natural contour as possible upon · Jan-2003 · LIESCIq ASSOCIATES, INC.
