Asphalt Paving Co <br /> February 7, 2019 <br /> Page 2 of 4 <br /> boundaries of such area; Please include all structures and utilities within the permit and within 200 <br /> feet of the permit area. <br /> Show the owner's name, type of structures, and location of all permanent or man-made structures <br /> contained on the area of affected land and within two hundred(200) feet of the affected land. This <br /> includes roadways, fencing, and underground utilities. This information will need to correlate with <br /> the structure damage waiver agreement information provided in Exhibit S. <br /> Please also show the general locations of topsoil and product stockpiles to be maintained on-site. <br /> EXHIBIT D -Mining Plan(Rule 6.4.4): <br /> The mining plan shall supply the following information, correlated with the affected lands, map(s) and <br /> timetables: <br /> Figure C-3 Conceptual view of western slope profile, shows a bench height from 40-100 feet,but <br /> Detail A -East dipping slope information text, and the included Brierley report, states bench height <br /> will vary from 40-80 feet. Please edit for consistency as needed. <br /> There is also no description in the mining plan as to who is conducting the blasting of the basalt. Will <br /> this be blasting be done by the permittee/operator, or subcontracted to a licensed blasting contractor? I <br /> am inferring at this time, based on the reports provided, that the blasting work is being conducted by <br /> Buckley Powder Company. <br /> EXHIBIT G-Water Information (Rule 6.4.7): <br /> DRMS has reviewed the Brierley hydrologic report provided in Appendix 2, and acknowledges that this <br /> operation is located in a somewhat unique geologic setting with respect to groundwater issues. However, <br /> a review of historic aerial photography shows an approximately 5.5 acre area of standing water in the <br /> bottom of the quarry that has existed at a relatively constant level since the fall of 2013. This would seem <br /> to indicate that either the pit began to intercept groundwater at that level and has equalized, or that <br /> precipitation collected in the pit has not been discharged into the natural drainage system within 72 hours <br /> as required by the State Engineer's Office(SEO). <br /> Please demonstrate to DRMS that groundwater has not been exposed in the bottom of the existing pit, and <br /> will not be encountered during mining as proposed. If groundwater has already been exposed in the pit <br /> bottom, Asphalt Paving will either need to backfill the area exposed to at least 2 feet above static water <br /> level, or achieve compliance with the SEO requirements for a well permit and substitute water supply plan <br /> until the pit passes the test for a sealed reservoir. If Asphalt Paving has already addressed this issue with <br /> the SEO please provide documentation. <br /> Exposure of groundwater in an unlined excavation will also have significant bonding implications. <br /> DRMS will be required to bond for backfilling the excavation to above static water level, or lining the <br /> excavation to meet the SEO standards for a sealed reservoir. <br />
