Pinyon <br /> 4. Conclusions and Mitigation Recommendations <br /> Pinyon has completed this Biological Resources Report for the Thunderbird Property Project in Pueblo County, <br /> Colorado. The study area was assessed for the presence of biological resources including federally and state- <br /> listed species, migratory birds, non-wetland waters and wetlands, and noxious weeds. <br /> 4.1 Threatened and Endangered Species <br /> 4.1.1 Federally Listed Species <br /> The study area was assessed for the federally listed species with the potential to occur in the study area or be <br /> impacted by the project. Based on the habitat present, the project would have no effect on federally listed <br /> species. Therefore, no further consultation or mitigation for this resource is required. <br /> 4.1.2 State-Listed Species <br /> The study area was assessed for ST, SE, and SC species with the potential to be impacted by the project. The <br /> Bald Eagle was identified as having potential to occur in the project area and is discussed below. <br /> 4.1.2.1 Bald Eagle <br /> Per CPW data, no Bald Eagle nests or winter roosts are located within 0.5 mile of the study area. However, <br /> Bald Eagles can build new nests and expand their winter roost habitat Because the site visits were conducted <br /> during the growing season, which reduces visibility, Pinyon recommends that the project perform additional <br /> nesting surveys prior to the commencement of work. If new (unmapped) Bald Eagle nests are noted, <br /> coordination with USFWS and/or CPW may be warranted. <br /> 4.2 Migratory Birds <br /> Potential habitat for nesting birds, including potential raptor nests, were identified in and within a 0.5-mile <br /> buffer of the study area.The nesting season for most birds generally occurs from April through August,although <br /> raptors may nest as early as February and nests are protected at all times. Pinyon recommends that the project <br /> complies with the MBTA at all times,as well as follow recommended guidelines set by CPW for nesting raptors. <br /> If active raptor nests are confirmed to occur within a 0.5-mile buffer of the project area prior to the onset of <br /> construction, it is recommended that a qualified wildlife biologist coordination with USFWS and/or CPW to <br /> identify an appropriate actions to ensure that project activities do not disrupt nesting activities. Pinyon also <br /> recommends that nesting surveys be completed for non-raptor species prior to construction if project activities <br /> occur during the nesting season. <br /> 4.3 Non-wetland Waters and Wetlands <br /> Non-wetland waters and wetlands occur in the study area. Martin Marietta intends to limit impacts to WUS, <br /> to the extent practical. The project will submit a request for a Jurisdictional Determination to the USACE to <br /> determine areas under the jurisdiction of the USACE. Prior to the beginning of work and after design is <br /> complete, impacts to WUS will be determined. If impacts to WUS are anticipated to occur, Section 404 <br /> permitting would be required. The type of permitting (Nationwide Permit or Individual Permit) will be <br /> dependent on the amount and type of impacts to WUS. If no impacts to WUS are anticipated,then no further <br /> action is required. <br /> Biological Resources Report <br /> Thunderbird Property <br /> Pueblo County, Colorado Page 12 <br />
