CDOW's concerns <br />focused around limiting the amount of suspended sediments being deposired in the Gunnison <br />River below Crystal: therefore. water quality issues were focused below Crystal. Preliminary <br />water quality data has been added to the Appendices. <br /> <br />Comment 3: Page 4, paragraph 4. Land and Facilities Resources: Will the road be closed to the <br />public during the entire two-month dredging process. or just during the 6 hour per day that <br />dredging activities are taking place? <br /> <br />Response: Traffic control measures (signing. flagging. and road closures) will be used to address <br />public safety issues associated with the narrow road and haul trucks. When equipment and <br />loaded trucks are using the road. the road will be closed to the public. When hauling is not <br />occuring. the road will be open to the public. <br /> <br />Comment 4: Page 5.

Do the impacts associated with <br />the off-site storage area need to be evaluated" <br /> <br />Response: The Colorado Department of Transponation will provide the off-site storage area and <br />impacrs associated with the olf-site storage area need to be evaluated. It is anticipated that the <br />gravel will be stored at an existing COOT storage site. however, if a new storage site is <br />developed. appropriated NEPA compliance would be needed. <br /> <br />Comment 6: Page 6, Statement 3: Should you be minimizing negative effects to trout resourses <br />"within" as well as below Crystal Reservoir. <br /> <br />Response: Concerns identified associated with trout resources focused around sediments being <br />deposited in the Gunnison River affecting trout spawning success. Trout do not spawn in Crystal <br />Reservoir. Temporary changes in water quality in Crystal as a result of the dredging is not <br />predicted to adversely affect trout resources in Crystal. <br /> <br />Comment 7: Page 9. Paragraph 9, Sentence I: should read "in conjunction with the construction <br />of the Aspinall Unit. <br /> <br />Response: "the" was added. <br /> <br />Comment 8: Page 9, Paragraph 5, Sentence I: should read ..... below the Black Canyon of the <br /> <br />25 <br />
