ENVIRONMENT, INC. PAGE 9 L.G. EVERIST, INC. - RAGSDALE RESERVOIR ADEQUACY RESPONSE 01 MAY 6, 2020 • Alfred Herman well (195505) - is located west of the railroad line and is no longer within 200 feet of the permit line. • Castle Pines well (15358R) -which is shown on the State Engineer's Map as being located on the southeast corner of Phase 4-A is not physically located there. It is actually located adjacent to Weld County Road 20 approximately 3050 feet to the southwest of the map location, so it is not located within 200 feet of the permit line. • Iona (Calvin) Wells-which are shown on the State Engineer's Map as being located in the very north east corner of the permit,area are not physically located there. A ground check was done for the 2 Iona (Calvin) Wells, and the wells were found 1000 feet from the permit area to the northeast. • Pacheco well - is a deep well having a total depth of 600 feet, so it will not be impacted by mining. • With the Herman, Castle Pines, and Iona (Calvin)wells physically located outside 200 feet from the permit area, there are only 3 shallow wells within 200 feet of the permit area. Of the 3 wells, only the McPeek well, located just on the north side of Phase 1-A will not be located next to a lined reservoir and could be impacted by dewatering. I added this information and made the necessary updated information and changes to Exhibit G Water Information, Table G-1 and Map Exhibit G-1 (revised 4/23/20). If during the course of mining or reclamation complaints from a well owner are received by the permittee, the permittee will commence an evaluation and investigation, including providing replacement water to the well owner if necessary, within 48 hours . DRMS shall be notified within two business days of the complaint and the proposed initial steps for the evaluation of the complaint . A written report will be submitted to DRMS within 30 days detailing the information collected during the investiga- tion of the complaint, and proposed mitigation activity, if required. Please make the appropriate edits to Exhibit G, and acknowledge the additional DRMS requirements listed above . I have made the edits to Exhibit G, and I presume you wanted this added to the Mitigation Plan, so it has been included there, too. EXHIBIT H - Wildlife Information Costs (Rule 6 .4 . 8) : Timely comments were received from Colorado Parks and Wildlife. This comment letter dated March 12 , 2020 has been forwarded to the permitting contact provided in the application via e-mail, and is also available for viewing through the imaged document data link provided at the end of this letter, or through the DRMS website . The primary topic of CPW concern is the proximity of the permit area to existing raptor nest (s) and habitat . CPW has provided suggested setbacks and date windows for activity restrictions in the comment letter. Please address how these suggestions will be implemented to minimize impacts to adjacent raptor nests and habitat . L.G. Everist, Inc. has retained Savage and Savage to investigate what needs to be done to
