A ERC UPG Site Threatened and Endangered Species Screening County. However, these species are not known to exist within the specific vicinity of the survey area and/or have specific habitat requirements (i.e., elevation range) that are not common in the vicinity of the survey area. common Nme iNerni Mexican spotted owl Strix occidentalis lucida Federally Threatened • The survey area does not contain the specific habitat characteristics necessary to support the species listed above.The species are not likely to occur within the survey area therefore any future land use changes would not likely adversely affect the continued existence or available habitat of the species. Water Depletions Species The USFWS under the ESA has determined that water depletions in the South Platte River Basin are considered an adverse effect to the listed species identified below. The survey area is considered to be located within the South Platte River Basin. OMMM Nme Scwwfic time stft" Least tern Sternula antillarium Federally Endangered Pallid sturgeon Scaphirhycchus albus Federally Endangered Piping plover Charadrius melodus Federally Threatened Western prairie fringed orchid Platanthera praeclara Federally Threatened Whooping crane I Grus Americana Federally Endangered Any water related project conducted in the Platte River Basin that has a federal nexus; such as federal funding or a federal permits (i.e., Clean Water Act (CWA) Section 404 Permit), is subject to ESA Section 7 Consultation with the USFWS. The consultation is a mandate for water depletion projects that may adversely affect threatened and endangered species that rely on the South Platte River. • The survey area does not contain the specific habitat characteristics necessary to support the species listed above.The species do not occur within the survey area therefore the proposed project and any future land use change will not directly adversely affect the continued existence or available habitat of the species. • The proposed project is an aggregate extraction operation (sand and gravel pit). As part of such operations, formalized augmentation plans are in place to ensure no water depletions occur. A hydraulically impermeable slurry wall is proposed to be installed around the perimeter of the mining operation impacts to ensure no depletions occur during project operations. It is assumed herein that proper augmentation plans are in place and the project will not result in a water depletion and therefore not be considered an adverse effect to these species. • Furthermore, it is assumed that no federal funding,federal permits, or federal authorization (federal nexus)would be required and therefore,South Platte River Basin depletion species are not concerned. • Based on these assumptions and our current understanding of the project, no adverse effect is likely to occur to these species. Species Potentially within Range of the Survey area The following federally listed threatened and endangered species are identified to occur or historically occur within Weld County(USFWS 2015). The Survey area is located within the potential known range for these species to occur. Further analysis was conducted to determine if the species or habitat has the 12
