eh ESPEY, HUSTON b ASSOCIATES, INC. \~ Based on one yeaz of intensive baseline vegetation sampling and wildlife monitoring, no threatened or endangered species of plants or animals or their habitats are known to exist as permanent residents on the mine plan area or adjacent areas. If any threatened or endangered plant or animal or its habitat is discovered on the mine plan azea, the regulatory authority will be notified in writing. Bald Eagles winter in stands of cottonwoods along the White River • ,: approximately 7 miles away, but do not use the mine plan area (see attached letters from BLM and USFW5). Golden Eagles are common year round residents of Colorado and are known to hunt the mine plan azea. No Golden Eagles are known to nest in the mine plan azea, but the regulatory authority will be notified in writing if any are observed to do so in the future. Two active Red-tailed Hawk nests occur on the mine plan azea (see Exhibit L-1). One nest is located near the southeastern boundazy (within approximately 500 feet) of the refuse disposal site. It is possible that the nesting pair will abandon this site with construction of the refuse disposal site. This pair may return the following season to nest, because once construction is completed, only about two dump trucks per day will dump rock waste. The other active nest is in an isolated area of the mine plan azea and will not experience human intrusion. Both active nests occur in aspen trees. The subsidence caused by underground mining could cause some aspen to fall. Active nest trees will be guyed prior to underground wining that area to prevent their falling. Monitoring of the mine plan azea for active raptor nests will occur once each year in June after the young have hatched to minimize the possibility of nest desertion. All future active nest trees will be guyed prior to underground mining. 0-4
