Adequacy Items <br />SIiB AGRA Project E92-7075 <br />i~i Page 16 <br />• ~~ 9i <br />Exhibit H -Wildlife Information <br />~, Please comment on the progress and results, if completed, of the black-footed ferret study <br />and the burrowing owl study. These studies will need to be completed and evaluated before <br />mining activity can begin. <br />You imply that raptor habitat enhancement substitutes for prairie dog town loss. Would <br />this create an imbalance of the raptors to prey ratio (i.e. too many raptors for the prey <br />base)? <br />Are the highwalls at the Lyons Quarry inhabited by cliff-nesting raptors? <br />v <br />Attachment 17 contains Rick Thompson's (project wildlife biologist) response to the wildlife <br />questions. Also attached (bound separately) is the Burrowing Owl report. <br />/)!-Iow will the speed be monitored ou haul trucks on haul roads (35 mph or less)? <br />The air quality permit requires vehicle speeds to be less than 20 mph (to control dust emissions). <br />S.8 down will self-monitor vehicle speeds for compliance purposes. <br />• ~ Exhibit .i -Vegetation Information <br />The Division will require that areas that have been seeded with the final mix be teoced for <br />at least 3 years or until new vegetation is established. <br />Sou~own accepts this requirement as discussed by Buchner (Attachment 9). <br />,Page 5 -you refer to a wetland study report noted as AWC 1987. Please provide this <br />V report to the Division. <br />Attachment 18 contains the referenced report. <br />., /9. Exhibit L -Reclamation Costs <br />As per the comments on the Mining and Reclamation Plans, please provide a bond <br />calculation at the time of maximum disturbance during the life of the mine. In completing <br />the reclamation cost estimate, please include; acreages of areas affected by each activity, <br />volumes of materials to be moved, haul distances, haul grades, a map showing a "snapshot" <br />of maximum disturbance on site, seed mixes and acreages to be seeded, building demolition <br />at conclusion of mining (including dimensions and compositions of superstructure, floor, <br />footings, quantities in linear feet, cubic feet, square feet where applicable), fencing <br />reclaimed areas, removing fence when revegetation is established, equipment to be used for <br />reclamation, and mob/demob charges. <br />AGRA <br />EerM & fmironmente/Croup <br />
