prior to seeding will likely result in erosion and weed control issues that will need to be <br />addressed. <br />6.4.6 EXHIBIT F - Reclamation Plan Map <br />No final reclamation has been shown for the stockpile area located to the southwest of the <br />Cell 4 area. Acreage around the perimeter of the pond areas does not seem to have been <br />accounted for. How will these areas be seeded? Have all the post-mining structures been <br />included on Exhibit F? If not, they will need to be added. Also please show roads that <br />will remain and roads that will be reclaimed on the Exhibit F map. <br />6.4.7 EXHIBIT G - Water Information <br />It appears based on the information in Exhibit G that there are a significant number of <br />wells, including several municipal, domestic, irrigation and livestock wells within 600 <br />feet of the proposed amended areas of operation. Because this is going to be a "wet <br />mining" operation DRMS would like to see appropriate groundwater modeling data to <br />show that these wells will not be impacted by the operations proposed. <br />On page 2 of the Groundwater Monitoring and Mitigation Plan provided in Exhibit G, it <br />is stated in the last sentence of the third bullet point under Groundwater Mitigation that: <br />"If, however, a subject well has not been put to beneficial use prior to mining then <br />Aggregate Industries would have no responsibility to provide mitigation". Please <br />remove this language from the application. Aggregate Industries will be responsible for <br />mitigation of any licensed well that DRMS has determined to have been adversely <br />impacted by Aggregate Industries activities, regardless of the well's use prior to mining <br />activities. <br />Please be aware that you will need to commit to not exposing groundwater in the <br />amended areas until proof is provided that the Substitute Water Supply Plan has been <br />approved, or you will be required to post a bond for 100% of the cost to backfill the <br />operation. If the Substitute Supply Plan has been approved by the State Engineer, please <br />provide verifying documentation. <br />Also the reclamation plan for the site has been changed from lined to unlined <br />groundwater ponds. The long-term water augmentation plan for the proposed unlined <br />lakes to be left on site after reclamation must also be approved by SEO prior to permit <br />approval. Please provide verifying documentation.
