These species are not lrnown to occur in Routt <br />County, and therefore on site or adjacent to the mine site, due to the lack of sightings and/or <br />habitat. <br />As the mine is in permanent cessation no impact to the species in Colorado that are <br />threatened, endangered or species of special concern at the state and/or federal levels or habitat is <br />expected. <br />2.7-63c Revised 11/06 <br />
