The black-footed ferret (Mustel niarioes) <br />t is the only listed species that may be present in the project area. <br />Historically, the black-footed ferret occurred throughout Colorado. Literature <br />and recent field studies document a close association between prairie dogs and <br />black-footed ferrets. The standard that is used by the Service for determining <br />possible project effects to black-footed ferrets is the disturbance of <br />currently occupied prairie dog habitat. Should any of the activities <br />associated with this project result in an impact fo prairie dogs, black-footed <br />ferret surveys may be necessary. As black-footed ferret surveys are considered <br />valid for one year, prairie dog towns surveyed more than one year prior to <br />construction may have to be resurveyed. <br />The Office of Surface Mining should review the proposed Federal action and <br />determine if the action would affect any listed species. If the determination <br />is "may affect" for listed species, your agency must request in writing formal <br />consultation from this office. At this time, your agency should provide this <br />office a biological assessment and/or any other relevant information used to <br />making the impact determil;ations. <br />C~ <br />
