Based on the proposed mine plan, there will be approximately 86.5 acres excavated for sand -~^~`~ , and gravel products. Assuming an average overburden depth of 5 feet, there will be 697,622 """'°-""~` cubic yards of overburden produced. The applicant states on page 13 that the overburden will be stockpiled along the perimeter of the azeas to be mined and ultimately used in reclaiming and sloping the shoreline. Please indicate the approximate volume or percentage of total overburden produced that will be used for the following: a) raising the elevation of the 9.5 acre Pod 5 Processing Area, b) backfilling the 7 acres of wetland bench areas to finish contours, and c) backfilling and grading the 15, 1561ineaz feet of shoreline. 7. The applicant states on page 16 of the application that they are in the process of applying for a well permit and required temporary substitute supply plan to augment evaporative loss from the mining operation. Please indicate if approval of either well permit or TSSP has been granted from the Office of the State Engineer (OSE). If not, please commit to obtaining approval of all required permits from the OSE prior to exposure of groundwater and/or dewatering at the Milliken Site. 8.

In order to demonstrate compliance with Rule 3.1.6 of the Construction Material Rules & Regulations the applicant will need to provide [he Division with one of the following items: A) A copy of the SEO's letter approving the proposed liner design and a copy of the design and specifications for inclusion into the applicant's application prior to the Division's recommendation date. B) A commitment to stay at least two (2) feet above the high water ground water level and an adequate means to monitor compliance until such time that written approval from the OSE for the liner design and specifications is achieved. C) Provide a financial warranty adequate to cover the cost of backfilling the pit to an elevation [ha[ is at least two (2) feet above the high ground water elevation.
