Obsolescence of 1973 Army Corps of Engineers flow and mapping data of the Dolores <br />River used by DMG in recommending approval of Line Camp Gravel Application <br />2, State has no data on effects of multiple gravel operations and pits in proximity in the <br />flood plain and into the aquifer on river and ground water quality and quantity. We <br />have found current monitoring of the existing Tam Pits inadequate and questionable. <br />There is no monitoring of the aquifer. <br />3. There will be approximately 28 restored and operational pits within a 5 mile stretch of <br />the river. We have hoted the death of Cottonwood trees and woody flora at the Tam <br />Pits, which diminishes the stability of the flood plain. <br />4. Increased serious flooding potential. Ponds abound, from Twin Spruce on downriver <br />and are the proposed reclamation for both the Tam and Line Camp Pits, Ponds greatly <br />diminish flood plain function and are subject to capture. We are also concerned about <br />silting of McPhee with resultant diminished water in the lower Dolores. <br />5. The presence of mercury has been documented in McPhee Resevoir. A most recent <br />E.P.A. report confInns significant mercury release from abandoned mines in Rico. Is <br />there mercury in the river bed? Has mercury been deposited in the flood plain? Does <br />gravel mining and discharge remobilize the mercury? <br /> <br />We look forward to meeting with you and possibly discussing these issues further during your <br />forthcoming visit to the Dolores area. Please feel free to call me, if we can be of assistance, <br /> <br />We would appreciate you sharing this information with the Board, since we have decided not to <br />take up their time at the next meeting. <br /> <br />71'- <br /> <br />Pa Kantor, Chairperson CF AR (Citizens for <br />Accountability & Responsibility) <br /> <br /> <br />A.,..,........'h_.......+- 1 <br />
