Mike Boulay -10- April 11, 2011 <br />on page 2.04-18. Historic Colorado River flooding information is added to <br />2.04.7(2)(i), page 2.04-19. <br />17. In Section 2.04.7(4)(b) of page 2.04-26, it is stated that the current surface water <br />users are the landowners who irrigate the land west of Loma Drain and north of <br />State Highway 6 & 50. However, there does not appear to be a map that shows <br />who these landowners are. Map 02, "Surface Ownership", does not show <br />sufficient aerial extent to the west and north. Please revised Map 02 to show all <br />relevant surface water users. <br />CAM: Map-02 has been revised to show a greater aerial extent to the West and <br />North of the Loadout property. Pages 2.03-4 & 5 have been revised with land <br />ownership information. Page 2.03-6 has been revised due to page numbering. <br />18. Referring to Map 08, "Hydrologic Monitoring Locations", please explain why <br />surface water monitoring stations US-1-13 and DS-LD are located as far <br />upstream as they are. US-LD is located about 3,000 feet upstream from the <br />permit boundary and DS-LD is located not even midway along the western edge <br />of the permit boundary. The downstream Loma Drain surface water sample <br />location (DS-LD) is actually located upstream of all disturbance areas proposed <br />for the loadout. Please clarify this or provide justification for this site selection. It <br />appears that a better site for downstream sampling on Loma Drain would be <br />further to the south where it exits the permit boundary similar to the site selection <br />for downstream Reed Wash (DS-RW). <br />CAM: An additional monitoring point, Lower Downstream Loma Drain (LDS) has <br />been added, and is included in Exhibit 3. Map-08 has been revised and shows <br />new monitoring point LDS. The US-LD is a convenient monitoring point along <br />County Road 13.5. Loma Drain flows through a culvert at this location so flows <br />can be determined. Land ownership is an issue in this area. The Applicant does <br />not have any right of entry between the upstream Loma drain monitoring point <br />and the permit boundary which is a distance of about 0.6 miles along the stream <br />channel. <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 <br />influenced by the adjacent gravel pits and by the flow from the upriver <br />Grand Valley Canal. <br />CAM: The DS-CR point was chosen because it is below the Loadout operations, <br />and access is readily available via the Loma boat ramp. It is unknown which <br />gravel pits the DRMS is referring to, but if it is the Gravel pit shown north of DS- <br />CR, that is a dry pit approximately 80' above the monitoring point. If DRMS is <br />referring to the Gravel pit East of the Loadout operation, that pit will affect <br />downstream results regardless of where a monitoring point is chosen.
