1 <br />WILDLIFE RESOURCES ASSESSMENT <br />CEMEX "C" PIT AND CKD DISPOSAL SITE <br />1.0 PURPOSE OF THE REPORT <br />_ _ . - <br />1.1 Introduction <br />' This report describes the wildlife habitat types and potential wildlife species present at <br />the Cemex "C" Pit site, identifies federal and state wildlife species of concern in the <br />habitat types present, and discusses potential impacts to wildlife from the presence of <br />approximately 100 acre feet of water in "C" Pit. Wildlife mitigation issues are discussed <br />in Section 6.0, including mitigation options. <br />' 1.2 Regulatory Jurisdiction <br />Cemex operates "C" Pit under a 112 permit with the Colorado Mined Land Reclamation <br />Board (Permit No. M-77-208). No federal permits or funding are required to operate the <br />' pit. Therefore, wildlife resources regulatory jurisdiction for "C" Pit is under the authority <br />of the Colorado Division of Minerals and Geology, with the Colorado Division of <br />Wildlife (CDOW) providing technical assistance. Afield consultation was held on <br />' August 6, 2004 with Windi Lassiter, the current District Wildlife Manager for the cement <br />plant area, and Sharlene Haeger with the Lon Hagler State Wildlife Area office in <br />Loveland. <br />2.0 REPORT METHODOLOGY AND FORMAT <br />Determination of wildlife habitats and wildlife species of concern was accomplished as <br />follows: <br />1. Previous vegetation and wildlife studies completed at the site were reviewed to <br />ascertain the level of effort completed within the analysis area, and identify additional <br />issues to be addressed. <br />2. Field reconnaissance was conducted to determine the wildlife habitats present within <br />the Project site, and analyze the relationship of "C" Pit to these habitats. <br />3. Discussions were held with the staff of the Colorado Division of Minerals and <br />Geology (DMG), and the Colorado Division of Wildlife (DOW). <br />4. A potential wildlife species list (vertebrates only) for the property was compiled <br />beginning with the Natural Diversity Information Source database for Boulder <br />County for amphibians, birds, mammals and reptiles (NDIS 2004). This county list <br />was then edited by the report preparer for the habitats present on the Property, and <br />checked with appropriate literature review (Andrews and Righter 1992, Kingery <br />1998, Fitzgerald et al. 1994, and Hammerson 1999). <br />
