Mike Boulay <br />14. Division Response: Response accepted. <br />15. Division Response: Response accepted. <br />15a. On page 2.05 -59 of the April 11, 2011 submittal, the first sentence states <br />that the Colorado River will not be monitored. Please correct this statement <br />since the river is part of the water monitoring program. <br />CAM - The statement now on page 2.05 -63 was clarified. The Colorado River is part of <br />the baseline monitoring program. CAM does not intend to perform routine <br />monitoring of the Colorado River beyond baseline collection. Please also see <br />response in item number 93. <br />16. Division Response: Response accepted. <br />17. Division Response: Response accepted. <br />18. Division Response: Response accepted. <br />-8- July 8, 2011 <br />19. Referring to Map 08, "Hydrologic Monitoring Locations ", please explain why <br />surface water monitoring station DS -CR is located where it might be influenced <br />by the adjacent gravel pits and by the flow from the upriver Grand Valley Canal. <br />CAM Response: The DS -CR point was chosen because it is below the Loadout <br />operations, and access is readily available via the Loma boat ramp. It is <br />unknown which gravel pits the DRMS is referring to, but if it is the Gravel pit <br />shown north of DS -CR, that is a dry pit approximately 80' above the monitoring <br />point. If DRMS is referring to the Gravel pit East of the Loadout operation, that <br />pit will affect downstream results regardless of where a monitoring point is <br />chosen. <br />In regard to potential impacts from the Grand Valley Canal, the person who <br />performs the monitoring will indicate when the Canal is flowing. <br />Division Response: In the submittal dated April 11, 2011, CAM responded that <br />the adjacent gravel quarry should not be a problem since it is 80 feet higher in <br />elevation than the river and is dry. CAM also responded that the water monitoring <br />sampler will note if the Grand Valley Canal is flowing. This may still be a problem <br />since noting the flow does not eliminate the problem of contaminating the river <br />sample with irrigation water. Please consider moving the river sampling <br />station upstream of the canal or show that the contribution of canal water <br />to the river will not measurably contaminate the sample. <br />CAM - The monitoring point will remain at the currently selected location because <br />the Colorado River will not be included in the long term monitoring plan. The <br />Colorado River upstream and downstream monitoring locations will be sampled <br />
