An addenda to the Second Adequacy review addressed several items from Exhibit G —Water Information and these are further considered in a separate Third Adequacy review from Leigh Simmons dated February 14, 2023. These items are addressed by exception per the item number in the February 14 review. Item 4. (additional review) Eight wells are listed, including two that are owned by Varra Companies and three more that are on the south side of the South Platte River which can be considered a groundwater divide. The three remaining wells (Shable, Dos Rios and Lafarge) are each within the modeled cone of depression, which suggests that there is the potential for their yield to be impacted by the proposed operation. The data presented suggests that the water level in the Shable well could be reduced by around 10', and a bit less in the Dos Rios and Lafarge wells. Since impacts to three existing wells are predicted, please address in Exhibit G how such impacts will be mitigated. It is likely that this will take the form of a signed agreement with the well-owner that can be included in the Exhibit. The three wells are all more than 200-feet from affected land included in this application. Physically, the Dos Rios well is north of the Big Thompson River which can also be considered a groundwater divide. In order to operate Raptor will need to obtain a well permit through the Colorado Division of Water Resources. This may or may not necessarily involve agreements with neighbors. Raptor commits to obtaining a well permit prior to operation. Item 5. (additional review) Several symbols are used on the map but are not identified in the key or labelled on the map, these include (by exception): • Dashed brown line (as shown in figure 2) • Blue marks(as shown in figure 3) —partially removed The map has not been signed, stamped, or otherwise certified by a registered land surveyor, professional engineer, or other qualified person. The revised map addresses some of the points from the previous adequacy review, but not all. In particular,the scale at which some of the labels are drawn renders them illegible, even at 300% zoom. The map has been digitally signed by Peter Christensen, but his qualifying credentials are not given. As mentioned above, an upload error inadvertently resulted in the Exhibit G map not being included in the supplemental response to Second Adequacy capture on the DRMS file system. The revised Exhibit G —Water Information Map, we believe addresses both the labeling of the Settling Basin (brown line), blue marks, and other extraneous feature that were unimportant to the intent of the map but nonetheless distracting. Efforts have been made to ensure labels are not obscured and legibility improved. We believe first and foremost that the important information required is clear and legible.
