Corey Heaps <br />CAM Colorado LLC <br />June 21, 2011 Page 54 <br />Please provide a map and discussion of agricultural activities including flood irrigated <br />lands, pasture lands and undeveloped rangelands. <br />CAM Response: New Map -22 shows the agricultural Iands. Vegetation measurement in <br />terms of productivity and type are shown on page 2.04 -32 and discussed in Volume 1 Tab <br />S, Vegetation. <br />Division Response: Response accepted. <br />108. The narrative in the permit application in Section 2.06.8 says the proposed permit area is <br />considered undeveloped rangeland. (This land use term is not used in the AVF report and <br />is not consistent with the land use information in Section 2.04.3). The same narrative also <br />references two topsoil samples indicating high sodic values. Please reference where the <br />samples are found in the permit. High sodic levels would be a limiting factor to agriculture <br />activities and should also be referenced in the AVF report. Please use consistent land use <br />types in Sections 2.04.3 and 2.06.8 of the permit application. Need to address undeveloped <br />rangeland and sodic comment sample location. <br />CAM Response: Page 2.06 -2 has been revised for consistency with PAP as well as AVF <br />report. TLO -2 and TLO -3 are part of the soils report and can be found in Exhbit 7. Table <br />1 discusses the 'strongly saline, and very highly sodic' nature of the soils samples, and test <br />results immediately follow Table 1. <br />Division Response: The narrative in the permit application in Section 2.06.8 states that two <br />out of three topsoil samples are very strongly saline. To strengthen this point, please <br />amend the text to include the additional topsoil sample TLO -4 which was taken in the <br />borrow area to the south of the main permit area. Also, please include a reference in the <br />text to Tab 7, Soil Resource Information (Baseline Survey) to clarify and support the <br />statement of poor soil conditions. <br />109 -110. Responses accepted and all items resolved. <br />111. Based on 2.06.8(3)(b)(vi), an analysis of a series of aerial photographs, including color <br />infrared imagery flown at a time of year to show any late summer or fall differences <br />between upland and valley floor vegetative growth and of a scale adequate for <br />reconnaissance identification of areas that may be alluvial valley floors need to be <br />submitted. ERO's report states they used an aerial photo from 1937 and a review of current <br />aerial photos. Please describe the results of the aerial photos as they relate to AVF <br />determinations. <br />CAM Response: CAM did not provide a specific response. <br />Division Response: ERO's report (page 3) states they used aerial photos of Mesa County <br />from 1937 to confirm NRCS's conclusion that the area was not cultivated prior to the <br />
